Description

Technical Field

[0001] This utility model relates to the field of elevator shaft technology, specifically to an elevator shaft protection device. Background Technology

[0002] An elevator shaft is the shaft through which elevators are installed. Elevator shafts are usually pre-reserved during building construction. To prevent falls from elevator shafts, current technology involves installing protective railings at the entrances to the walls connected to the elevator shaft.

[0003] While existing technologies can facilitate fall protection by installing temporary fences, they inevitably have shortcomings in actual installation. One such shortcoming is the lack of a non-destructive installation mechanism, which means that traditional fences require drilling for fixing, making installation inconvenient. Therefore, an elevator shaft protection device is proposed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an elevator shaft protection device that solves the problem of inconvenient installation caused by the lack of a non-destructive installation mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator shaft protection device, comprising a first L-shaped plate and a second L-shaped plate, wherein the second L-shaped plate is slidably disposed on the rear side of the first L-shaped plate, and an internally threaded cylinder is rotatably connected to one side of the inner cavity of the first L-shaped plate. A threaded rod is threadedly connected to the inner side of the internally threaded cylinder, and one end of the threaded rod is fixedly connected to a support column via a bracket. One side of the support column is fixedly connected to the inner wall of the second L-shaped plate. A bracket is fixedly connected to the top and bottom of the opposite sides of the first L-shaped plate and the second L-shaped plate. Ball bearings are provided on the front and rear sides of the bottom of the first L-shaped plate and the second L-shaped plate.

[0006] Preferably, a cover plate is rotatably provided on the front side of the first L-shaped plate, and a lock hole seat is fixedly connected to one side of the cover plate and the front side of the first L-shaped plate.

[0007] Preferably, the rear side of the card holder is threadedly connected to a threaded adjusting rod via a threaded groove, and one end of the threaded adjusting rod extends into the interior of the card holder, with a movable plate rotatably connected to the end of the threaded adjusting rod.

[0008] Preferably, a limiting groove is fixedly provided at the top and bottom of the rear side of the first L-shaped plate, and a limiting slider is slidably connected inside the limiting groove, and the rear side of the limiting slider is fixedly connected to the front side of the second L-shaped plate.

[0009] Preferably, the inner wall of the card holder has two symmetrically formed guide grooves, and a guide slider is slidably connected inside the guide groove, and the guide slider is fixedly connected to the side of the movable plate.

[0010] Beneficial effects

[0011] This utility model provides an elevator shaft protection device. Compared with the prior art, it has the following advantages: This utility model sets a bracket on the opposite side of the first L-shaped plate and the second L-shaped plate, and sets an internal threaded cylinder and a threaded rod between the first L-shaped plate and the second L-shaped plate. This allows the first L-shaped plate and the second L-shaped plate to be expanded through the internal threaded cylinder and the threaded rod. Correspondingly, the first L-shaped plate and the second L-shaped plate can also be engaged with the wall through the bracket, making it easy and non-destructive to fix the device to the wall at the entrance of the elevator shaft, achieving the effect of non-destructive and convenient installation. Secondly, a threaded adjustment rod and a movable plate are set inside the bracket, so that the engagement gap inside the bracket can be easily adjusted to adapt to walls of different thicknesses.
