Specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In order to solve the technical problem set forth in the background art, in one example of the present application, an auxiliary mounting device for a detector is provided, which is used for moving the detector in the stages of PET equipment production and maintenance, etc., so as to facilitate the mounting of the detector.

Referring to fig. 1 to 4, for example, the auxiliary mounting device generally includes: the locking mechanism 100, the unlocking mechanism 200 and the moving mechanism 300 may further comprise a cross beam 400, a distance adjusting mechanism 500 and other structures. The locking mechanism 100 is used for locking the detector 001 before moving the detector 001, the moving mechanism 300 is used for moving the detector 001, the unlocking mechanism 200 is used for releasing the detector 001 when the detector 001 is moved into place, the cross beam 400 is a main supporting structure, and the distance adjusting mechanism 500 is used for adjusting the size of the locking mechanism 100. The auxiliary installation device can replace the manual lifting of the detector 001, so that the safety and the efficiency of the detector 001 in the installation process are greatly improved, the detector 001 with different sizes can be adapted, and the application range of the auxiliary installation device is further improved.

Specifically, the locking mechanism 100 has a first state (see fig. 2) in which the locking mechanism 100 locks the detector 001, and a second state (see fig. 1 and 3). More specifically, the locking mechanism 100 includes a fixed plate 110 and a movable plate 120, and locking members 130 are disposed on both the fixed plate 110 and the movable plate 120, and the locking members 130 are disposed adjacent to the detector 001. In one example, the locking member 130 includes a hanging pin having one end connected to the fixed plate 110 or the movable plate 120 and the other end for connection to the detector 001. Further, the fixed plate 110 and the movable plate 120 are both connected with two hanging pins, and the hanging pins are adapted to preset holes on the detector 001 and can be directly connected with each other, wherein the preset holes are reserved in the production stage of the detector 001, and the preset holes can be used for connecting the detector with other positions such as preset mounting positions except for the adaptation of the hanging pins. Illustratively, in the first state, the fixed plate 110 and the movable plate 120 are both connected to the detector 001 via the corresponding locking members 130; in the second state, the fixed plate 110 is connected to the detector 001 through the corresponding locking member 130, and the locking member 130 corresponding to the movable plate 120 is separated from the detector 001. It will be appreciated that, in the first state, the movable plate 120 and the fixed plate 110 are respectively connected to opposite sides of the probe 001, so as to achieve the purpose of clamping the probe 001.

In one example, referring to fig. 5 to 9, the locking mechanism 100 further includes a pull rod hook 140, where the pull rod hook 140 has a first end 141 and a second end 142 opposite to each other, the second end 142 is provided with a drag hook, and the movable plate 120 is provided with a clip 121 that mates with the drag hook. The first end 141 is directly or indirectly connected to the unlocking mechanism 200, and the first end 141 is controlled by the unlocking mechanism 200 to move so as to drive the draw hook and the clamping piece 121 to switch from the connection state to the separation state, so that the locking mechanism 100 is switched from the first state to the second state. It will be appreciated that, here, the connection state of the draw hook to the latch 121 corresponds to the first state, and the disconnection state of the draw hook to the latch 121 corresponds to the second state. The pull rod hook 140 is used for fixing the movable plate 120 in the first state, so as to avoid the movable plate 120 loosening when clamping the detector 001 to cause the detector 001 to fall off.

More specifically, the locking mechanism 100 further includes a first return torsion spring 150 for urging the locking mechanism 100 to the second state when the connection state of the retractor and the clip 121 is released, and releasing the probe 001 more automatically.

More specifically, the locking mechanism 100 includes a mounting structure 160, where the mounting structure 160 is connected to the movable rod 520, and may be connected to other mechanisms or structures, for example, to the cross beam 400, and the mounting structure 160 is used to mount the draw bar hook 140.

More specifically, the locking mechanism 100 further includes a second return torsion spring 143 (see fig. 8), the second return torsion spring 143 is connected to the pull rod hook 140, and the second return torsion spring 143 is configured to drive the pull rod hook 140 to return to the initial position when the unlocking mechanism 200 releases the control of the first end 141. Alternatively, the second return torsion spring 143 is disposed between the mounting structure 160 and the pull rod hook 140, and is used to drive the pull rod hook 140 to return to the initial position when the unlocking mechanism 200 releases the control of the first end 141, so as to connect the pull rod hook 140 with the movable plate 120 when the detector 001 is mounted and moved next time.

It will be appreciated that the second return torsion spring 143 is typically sleeved on the shaft to enhance its stability.

Specifically, the unlocking mechanism 200 is configured to actuate the locking mechanism 100 to the second state to unlock the detector 001. More specifically, the unlocking mechanism 200 is connected to the movable plate 120, and it is understood that the connection of the unlocking mechanism 200 to the movable plate 120 may be direct or indirect. Further, in one example, referring to fig. 9, the unlocking mechanism 200 includes an unlocking block 220, an unlocking buckle 210, and an unlocking pull cord 230 (fig. 4). The unlocking block 220 includes a connection portion and a body 221, and the unlocking buckle 210 is connected to the connection portion, where the connection portion may be understood as a connection portion between the unlocking block 220 and the unlocking buckle 210. The unlocking pull rope 230 is connected to the unlocking buckle 210, and the unlocking pull rope 230 controllably pulls the unlocking buckle 210 in a first direction, so that the body 221 abuts against the first end 141 and drives the first end 141 to move, so as to drive the draw hook and the clamping piece 121 to switch from a connection state to a separation state, and further switch the locking mechanism 100 from the first state to the second state. It will be appreciated that pulling of the release pull cord 230 may be manual or automatic, preferably automatic, such as motor driven. Illustratively, the first end 141 is disposed higher than the second end 142 as shown in fig. 8, and the first direction is a direction away from the movable plate 120, illustratively, the first direction is a direction along the axial direction of the guide rod 320 and away from the movable plate 120. When the first end 141 is driven by the body 221, the pull rod hook 140 rotates, and the first end 141 and the second end 142 rotate counterclockwise around the second return torsion spring 143, so that the connection state between the drag hook and the clamping piece 121 is released.

It should be noted that, in the present application, the unlocking pull cord 230 may be fixed in various manners. In some examples, the unlocking pull cord 230 may be fixed as shown in fig. 1, and the unlocking pull cord 230 is fixed by a pull buckle cooperating with other structure of the auxiliary installation device; in some examples, the unlocking pull cord 230 may be further fixed by a pulley and other various structures, as shown in fig. 3, and the fixing manner shown in fig. 3 will be described in detail below.

More specifically, the bottom of the body 221 is provided with a first inclined surface, the first end 141 is provided with a second inclined surface, the first inclined surface and the second inclined surface are adapted, and the unlocking pull cord 230 is controlled to pull the unlocking buckle 210 in a first direction, the first inclined surface is abutted against the second inclined surface (see fig. 5), so that the pull rod hook 140 is rotated.

In a specific example, with continued reference to fig. 9, the unlocking mechanism 200 further includes a guide rail 250 and a slider 260.

Specifically, the unlocking block 220 is connected to the slider 260, and the unlocking block 220 is configured to be relatively movable with the slider 260 under the pulling of the unlocking pull rope 230, so as to realize the abutment of the first inclined plane and the second inclined plane.

In some examples, the unlocking block 220 is disposed above the slider 260.

Specifically, the guide rail 250 has one end fixed and the other end connected to the slider 260, and the guide rail 250 is configured to allow the slider 260 to controllably slide in the first direction. Further, the unlocking mechanism 200 is connected to the movable plate 120 through the slider 260, the slider 260 is connected to the movable plate 120 through a rotation shaft 261, so that the movable plate 120 can be rotated around a shaft, and the movable plate 120 is rotated to a third state (see fig. 16 and 17) in which the movable plate 120 does not interfere with the probe 001 as the unlocking pull cord 230 is pulled, so that a side of the probe 001 near the movable plate 120 is exposed, so that the probe 001 is mounted to a predetermined mounting area.

Illustratively, the first return torsion spring 150 is sleeved on the rotating shaft 261, and the first return torsion spring 150 is configured to be compressed when the locking mechanism 100 is in the first state, so as to urge the movable plate 120 to spring to the second state when the connection state of the draw hook and the clamping piece 121 is released.

Specifically, in one example of the present application, the manner of fixing the unlocking pull cord 230 is the manner shown in fig. 3, and referring to fig. 10 to 13, the unlocking mechanism 200 further includes a pull cord tensioning wheel 241, a limit housing 242, a pull cord connection block 243, an unlocking pull rod 246, and a shift shaft 247. The pull cord tensioning wheel 241 is used to tension the unlocking pull cord 230. At least two pin holes 244 (fig. 2) are formed in the limit housing 242, and the pin holes 244 are communicated, for example, the number of the pin holes 244 is three, and the three pin holes 244 are on a straight line. The pull cord connection block 243 is connected to an end of the release pull cord 230 remote from the movable plate 120. The function of the cord connection block 243 is to facilitate the securement of the release cord 230. The unlocking pull rod 246 is a hollow barrel body, the unlocking pull rod 246 can be connected with the limit housing 242 through any pin hole 244, when the unlocking pull rod 246 is connected with the limit housing 242, the unlocking pull rope 230 is fixed, and when the unlocking pull rod 246 is separated from the limit housing 242, the unlocking pull rope 230 is released. The transposition shaft 247 is arranged in the unlocking pull rod 246 in a penetrating manner, both ends of the transposition shaft 247 extend out through the unlocking pull rod 246, one end of the transposition shaft 247 is connected with the pull rope connecting block, and the unlocking pull rod 246 can be switched between different pin holes 244 by controlling the unlocking pull rod 246 and/or the transposition shaft 247, so that the tightness of the unlocking pull rope 230 is adjusted.

For example, referring to fig. 12 and 13, a spring 2453 is disposed between the index shaft 247 and the unlocking pull rod 246, as shown in fig. 12, the unlocking pull rod 246 is inserted into a pin hole 244 under the action of the spring 2453, and the unlocking pull rod 246 cannot move up and down; when the index shaft 247 is forced, the unlocking pull rod 246 is pulled out and separated from the pin hole 244, the spring 2453 is compressed to reach the state shown in fig. 13, at this time, the unlocking pull rod 246 can move up and down, the position of the unlocking pull rod 246 is adjusted according to the requirement, and after the unlocking pull rod 246 is in place, the unlocking pull rod 246 can be connected with the current pin hole 244 to be fixed under the action of the spring 2453.

In one example of the present application, taking the number of the pin holes 244 as two, the two pin holes 244 are named as a second pin hole 2442 and a third pin hole 2443 according to the tightness degree of the unlocking pull rope 230 from tight to loose, when the unlocking pull rope 246 is disposed in the second pin hole 2442, the unlocking pull rope 230 is loose, and no or little force is generated on the unlocking lock 210 (the force cannot realize unlocking), so that the detector 001 can be locked in the second pin hole 2442; when the unlocking pull rod 246 is disposed in the third pin hole 2443, a large force is applied to the unlocking buckle 210 (the force is sufficient to unlock), and the unlocking buckle 210 is pulled to move the unlocking block 220 along the first direction, so as to drive the pull rod hook 140 to rotate, thereby unlocking.

In one example of the present application, taking the number of the pin holes 244 as three as an example, the three pin holes 244 are named as a first pin hole 2441, a second pin hole 2442, and a third pin hole 2443 in order from tight to loose in terms of tightness of the unlocking pull cord 230.
