Detailed Description

A pneumatic training equipment launching mechanism comprises a launcher box, a trigger spring, a connecting rod spring, a release rod spring, a sear spring, a sear top spring, a positioning handle, a continuous sear spring, a short-in-place safety, a trigger shaft, a handle spring, a positioning handle head, a launcher shaft, an elastic pin 2 multiplied by 4 and a speed machine. The sear top spring is a compression spring, and the other springs are torsion springs. The transmitter box is provided with a pin hole, a trigger spring, a sear spring, a sear top spring, a positioning handle, a continuous sear spring and a short-of-place safety are arranged on the transmitter box through the transmitter shaft, and a fast and slow machine mounting hole is arranged to fix the fast and slow machine on the transmitter box; the trigger is provided with two holes, one hole is used for being fixed with the transmitter box, and the other hole is used for being connected with the connecting rod, the release rod, the connecting rod spring and the release rod spring; the positioning handle is provided with a positioning handle head and a handle spring mounting hole and is fixed on the positioning handle through an elastic pin 2 multiplied by 4, so that the positioning handle moves up and down. The speed machine is provided with 3 positions (0, 1 and 2), and the rotation stroke of the trigger and the connecting rod is limited by utilizing the structure on the speed machine through converting different positions, so that the shooting mode of the training equipment is controlled, and the functions of single shot, continuous shot and insurance are realized.

The transmitter box is designed with 5 pin shaft holes for assembling a trigger, a trigger spring, a sear spring, a sear top spring, a positioning handle, a continuous sear spring, an out-of-place safety and a speed machine. Under the premise that the internal space of the pneumatic training equipment is enough, the pneumatic transmitter mechanism is suitable for all pneumatic training equipment designs.

When the product is ventilated, the firing release block is hung by a sear part in the launching mechanism. When the speed reducer rotates to the 0 number position (namely, the 0 number on the speed reducer is opposite to the horizontal position), the trigger cannot rotate through the corresponding limiting structure of the speed reducer, so that the sear cannot rotate, the firing release block is released, and the safety function is realized; when the speed reducer rotates to the '1' position (namely, the '1' on the speed reducer faces the horizontal position), the trigger and the connecting rod rotate together by a certain angle through the corresponding limiting structure of the speed reducer, after the connecting rod rotates by a certain angle, the connecting rod is limited by the speed reducer and cannot rotate continuously, but the trigger can still rotate continuously, the sear is propped against and rotates by the release rod, and after the trigger continues to buckle a certain stroke, the trigger releases the firing release block, so that firing is realized; after the trigger is triggered, a notch is arranged on the sear, the sear is reset under the action of the sear top spring, the trigger release block is hung by the sear again, and the trigger can be triggered only after the trigger is released, so that the single-shot function is realized. When the speed regulator rotates to the No. 2 position, the connecting rod is limited by the speed regulator and cannot rotate, at the moment, the trigger independently rotates, the sear is propped against and rotated after rotating by a certain angle, the trigger is released to trigger the trigger release block to realize triggering, at the moment, the trigger is locked, and the trigger rotation angle is smaller than that of a single trigger, the sear is still propped against by the release rod after being reset and cannot be reset, and the trigger release block reciprocates under the action of gas to realize the continuous triggering function.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in FIG. 1, the speed machine rotates to the 0 position, the limiting surfaces of the connecting rod and the trigger are blocked by the excircle of the speed machine and cannot rotate, the release rod cannot push the sear upwards, the firing release block is released, and the safety function is realized.

As shown in fig. 2, when the speed regulator is rotated to the 1 position, the trigger is pulled at this time, the connecting rod rotates along with the trigger, and after the connecting rod rotates for a certain angle, the connecting rod is blocked by a limiting structure on the speed regulator, and the trigger can continue to rotate to drive the release rod to push up the sear, so that the sear rotates, and the firing release block is released, and firing is realized; as shown in fig. 3, when the firing release block moves forward under gas pressure, the sear returns to the original position under the action of the sear top spring, and is caught by the sear when the firing release block is seated again. At this time, only when the trigger is released, the trigger release block can be released again after the trigger is triggered again, so that the single-shot function is realized.

As shown in FIG. 4, when the speed regulator is rotated to the 2 position, the trigger is pulled at this time, the connecting rod is limited by the speed regulator, the trigger rotates by a certain angle (smaller than the rotation angle in the single shot state), and the release rod props against the sear along with the rotation of the trigger, so that the trigger limiting block is released to realize the trigger. As shown in FIG. 5, when the trigger continues to be locked, the trigger release block is not limited by the iron and reciprocates due to the fact that a < b, namely, the front and back strokes of the release rod against the sear are larger, the sear cannot return to the initial position due to the fact that the stroke of the sear, which cannot be reset under the action of the sear top spring, is shorter, and the continuous firing function is achieved.

Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
