Description

Technical Field

[0001] The utility model relates to the technical field of elevator connecting plates, in particular to a self-locking and anti-loosening elevator connecting plate. Background Art

[0002] Vertical lifts are now an essential means of transportation for high-rise residences. When installing a vertical lift, the elevator guide rails need to be fixed first, and a connecting plate is required to cooperate with the installation of the elevator guide rails in the elevator shaft.

[0003] The existing general elevator guide rail connecting plates are connected by bolt structures. When fixing with bolts, the bolts need to be inserted into the through holes and then tightened with nuts to fix the connecting plate and the guide rails. When tightening the screws, the connection position of the connecting plate and the elevator guide rails must be calibrated at all times, which is inconvenient to install and has low installation efficiency. If the nuts loosen and fall off from the bolts, the elevator guide rails may also loosen and fall off from the connecting plates, posing a safety hazard. For this reason, we have designed a self-locking and anti-loosening elevator connecting plate to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and a self-locking and anti-loosening elevator connecting plate is proposed, which allows multiple support rods to pass through the corresponding mounting holes on the elevator guide rails respectively, and the self-locking block can be abutted against the upper surface of the elevator guide rails to connect and self-lock the elevator guide rails. The elevator guide rails are initially fixed to the connecting plate body, and the internal threaded ring is screwed on the threaded rod and the annular clamping plate is extended into the groove on the self-locking block. The self-locking block can be stably fixed so that it cannot move horizontally, and the elevator guide rails are further stably connected to the connecting plate body to prevent the elevator guide rails and the connecting plate body from loosening and falling off, and the operation is simple.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] Preferably, a groove is formed at the upper end of the self-locking block, and an annular clamping plate is fixedly connected to the bottom of the internal threaded ring, and the annular clamping plate extends into the groove.

[0011] Preferably, the cross section of the screwing block is polygonal.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The self-locking and anti-loosening elevator connecting plate makes multiple support rods face the corresponding mounting holes on the elevator guide rails respectively, and makes the support rods pass through the corresponding mounting holes. When the elevator guide rail abuts against the upper end of the self-locking block, the self-locking block can be pushed to slide into the horizontal slide groove.
