The locking assembly 3 includes a retainer 31 and a second roller 32. The power cord 4 is wound around the first roller 23 and the second roller 32, and the holding member 31 is movably disposed on one side of the second roller 32. The power cord 4 wound around the second roller 32 is interposed between the chucking member 31 and the second roller 32. When the holding member 31 moves away from the second roller 32, the sliding block 22 moves toward the fixed block 21 by an elastic force to drive the power cord 4 to be accommodated in the housing 1.
Still be connected with elevating system 5 below casing 1, power cord 4 certainly elevating system 5 is inside stretches into in the casing 1. In an alternative embodiment, the lifting mechanism 5 can be used as a leg of a lifting table, the table top of which is arranged above the housing 1. With reference to fig. 2, the locking assembly 3 further includes a pushing member 33, a rotating member 34, a rotating shaft 37 and a second elastic member 35, all disposed on a side of the holding member 31 away from the second roller 32. One end of the pushing element 33 extends out of the side of the casing 1, the other end of the pushing element abuts against one end of the rotating element 34 in the casing 1, and the other end of the rotating element 34 abuts against the clamping element 31. The rotating member 34 is rotatably mounted on the rotating shaft 37, one end of the second elastic member 35 is connected to the retaining member 31, and the other end is fixed on the inner side wall of the housing 1. The pushing member 33 drives the rotating member 34 to rotate to press the holding member 31, and the second elastic member 35 is compressed to make the holding member 31 away from the second roller 32.
Further, the locking assembly 3 further includes a third elastic element 36, and the third elastic element 36 is used for driving the rotating element 34 to return. One end of the third elastic element 36 is fixed in the housing 1, and the other end is connected to one end of the rotating element 34 close to the pushing element 33. Pressing one end of the pushing member 33 extending out of the housing 1 moves the pushing member 33 into the housing 1, so as to drive the rotating member 34 to rotate around the rotating shaft 37 toward the holding member 31, the third elastic member 36 is compressed, and the holding member 31 is pressed by the rotating member 34.

Further, the locking assembly 3 includes a first limiting member 38 and a second limiting member 39, where the first limiting member 38 and the second limiting member 39 are respectively disposed on two opposite sides of the rotating member 34, and are spaced from the rotating member 34 to limit the rotation range of the rotating member 34. Specifically, the first limiting member 38 is detachably disposed on a side of the rotating member 34 away from the side wall of the housing 1, and the second limiting member 39 is detachably disposed on a side of the rotating member 34 facing the side wall of the housing 1. When the two ends of the rotating member 34 respectively abut against the first limiting member 38 and the second limiting member 39, the rotating member 34 presses the holding member 31 to move to the farthest position to release the power cord 4.
Referring to fig. 1 and 4, a guide plate 11 is disposed on the bottom surface of the housing 1, and the guide plate 11 is spaced from the bottom surface of the housing 1. A through groove 12 is formed in the guide plate 11, the through groove 12 is approximately formed in the middle of the guide plate 11, and the sliding block 22 is movably installed in the through groove 12. Specifically, the slide block 22 is provided with a slide portion 221 on a side (bottom) facing the guide plate 11, and the slide portion 221 is received in the through groove 12 and is movable along the through groove 12. A limiting plate 222 is arranged on one side of the guide plate 11, which is away from the sliding block 22, and the width of the limiting plate 222 is greater than that of the through groove 12. The sliding portion 221 is coupled to the stopper plate 222 by a fastener, thereby preventing the sliding portion 221 from coming out of the through groove 12. One side of the sliding block 22 facing the fixed block 21 is further provided with a pull ring 223, and the first elastic element 24 is connected with the pull ring 223 to drive the sliding block 22 to reset.
The first roller 23 is rotatably mounted in the sliding block 22 and is located approximately in the middle of the sliding block 22. A first receiving groove 231 is formed on the circumferential surface of the first roller 23, and the power cord 4 drawn to the first roller 23 is wound in the first receiving groove 231. The automatic power line take-up mechanism 100 further includes a third roller 41 installed in the housing 1. The guide plate 11 is further provided with a through hole 13, and the power cord 4 extending out of the top end of the lifting mechanism 5 enters the shell 1 through the through hole 13. The third roller 41 is disposed at an end of the housing 1 away from the sliding assembly 2, the power cord 4 extending from the through hole 13 is wound around the third roller 41, drawn from the third roller 41 to the first roller 23, and wound from the first roller 23 to the second roller 32, and a plug end of the power cord 4 extends out of the housing 1.
In the embodiment of the present application, the second roller 32 and the third roller 41 correspond to a fixed pulley, and the first roller 23 corresponds to a movable pulley. When the clamping member 31 does not abut against the power cord 4, the plug end of the power cord 4 can be dragged to pull out the power cord 4 for use, the first roller 23 and the sliding block 22 move along the through groove 12 along with the dragging out of the power cord 4, and the first elastic member 24 connected between the sliding block 22 and the fixed block 21 is stretched. When the power cord 4 is pulled out by a required length, the pushing force on the pushing member 33 is removed, so that the holding member 31 again abuts against the power cord 4, and the power cord 4 is prevented from retracting. When the power cord 4 is not needed to be reused, the pushing member 33 is directly pressed, the holding member 31 is separated from the power cord 4, and the sliding block 22 moves towards the fixed block 21 under the action of the elastic force, so that the power cord 4 is driven to be accommodated in the housing 1 again.
The automatic power line take-up mechanism 100 provided by the invention has the advantages that the power line 4 can be orderly and automatically accommodated in the shell 1 through the mutual matching of the clamping piece 31, the sliding block 22, the first roller 23 and the second roller 32, so that the power line 4 is effectively protected, and the damage of the power line 4 caused by the fact that the redundant power line 4 is exposed outside the shell 1 is avoided.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention.
