There is a lack of structure to limit and clamp the counterweight blocks.

[0003] The Chinese patent with publication number CN218174347U discloses a counterweight device for a traction elevator, comprising a lower plate, the upper surface of which is fixedly connected to a connecting plate, the inner wall of which is slidably connected to a counterweight block, the upper surface of which is provided with a mounting hole, the inner wall of which is sleeved with a fixing rod, the bottom end of which is threadedly connected to the upper surface of the lower plate, the surface of which is threadedly connected to a nut, the front of which is fixedly connected to a fixing plate, and the front of which is threadedly connected to a threaded limiting rod. The limiting plates are sequentially inserted into the limiting holes in the support columns, and then the support columns are welded to the upper plate. The limiting holes of the limiting plates separate each limiting plate, and rubber rings are provided on the limiting plates to reduce friction caused by direct contact between the limiting plates during operation, thereby enabling the device to limit each return rope.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0012] Optionally, the pushing structure includes a sleeve fixedly connected to the bottom wall of the box body, the top surface of the sleeve is fixedly connected to a spring, the top surface of the spring is fixedly connected to a sliding rod, the sliding rod is slidably connected to the inside of the sleeve, the top surface of the sliding rod is fixedly connected to a push rod, and the surface of the push rod is provided with a conical push block.

[0013] Optionally, both ends of the clamping rod are provided with a rotation groove, the side surfaces of the rotation groove are provided with rotation holes in an axially symmetrical manner, and the interior of the rotation groove is rotatably connected to a roller through the rotation holes.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0015] 1. Through the setting of the connection component, the weight sensor inside the elevator detects the change of weight, and the controller electrically connected controls the drive motor to start working. The screw rod fixedly connected to the output end of the drive motor rotates, and the screw rod moves downward inside the threaded hole opened on the top surface of the counterweight block, so that the screw rod moves downward and gradually threads through more counterweight blocks until the counterweight blocks are stacked to fit the internal weight of the elevator.
