Description

Technical Field

[0001] The utility model relates to the technical field of length-adjustable elevator pull rods, in particular to a length-adjustable universal elevator pull rod. Background Art

[0002] The elevator inclined tie rod is an important component connecting the car bottom beam and the car frame straight beam, which plays a stabilizing role in the connection between the car and the car frame. In the actual use of the elevator, different car heights and car depths often have different length requirements for the elevator inclined tie rod. In order to achieve the goals of unified procurement, management, and delivery, manufacturers often design the tie rod into a universal structural mode. At present, the means to achieve universal use of the tie rod is to design the tie rod into two adjustable connected sections, one of which is provided with a threaded connection hole, and the other section is connected to the threaded connection hole through a connecting thread. The length of the tie rod can be adjusted by the threaded connection method. The weight distributed in the car is heavier as it is farther away from the straight beam in the front and rear directions, and the car bottom beam is more likely to bend downward. Correspondingly, the tie rod has a tendency to bend downward with the connection between the tie rod and the straight beam as the fulcrum. Reflecting on the above-mentioned universal tie rod, the entrance of the threaded connection hole is easy to be expanded relative to other parts on the tie rod, and the threads on the connecting threads and the threaded connection holes are easy to fail, and the probability of tie rod failure increases.

[0003] However, in the prior art, when the prior art is actually used, the elevator pull rod cannot be adjusted in length and cannot adapt to elevator doors of different sizes, which reduces the flexibility of use and makes installation and maintenance more complicated. The installers need to cut and process according to the length requirements. Utility Model Content
