Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling rods, in particular to an anti-falling rod for elevator maintenance. Background Art

[0002] As people's quality of life improves, elevators are used in more and more places. Elevators need regular maintenance and repairs. During maintenance and repairs, users need to fix the safety rope to the anti-fall rod installed at the elevator door when conducting inspections in the elevator shaft.

[0003] When the elevator needs to be repaired, it needs to be repaired in the elevator shaft. The user fixes the safety rope on the anti-fall rod, but during the repair process, the anti-fall rod is easy to shake, causing the anti-fall rod to tilt, and it is easy to cause the anti-fall rod to fall, thereby causing injuries to the user. If the user unfortunately steps on the air and falls, the impact force generated by the safety lock is easy to cause injuries to the user;

[0004] The utility model with the search announcement number CN220537256U discloses an anti-fall rod for elevator maintenance. By setting a stabilizing mechanism, the anti-fall rod can be fixed on both sides of the elevator door. During the user's maintenance process, the anti-fall rod can be fixed on the walls on both sides of the elevator door, which increases the stability of the anti-fall rod and prevents the anti-fall rod from shaking when the user is inspecting the elevator shaft, and is prone to tilting or even falling into the elevator shaft, thereby ensuring the safety of the user.

[0005] The device uses a motor-driven method to adjust the position of the rotating block using a threaded connection. Firstly, the energy supply of the motor has certain usage limitations during elevator maintenance. Secondly, the device has a relatively complex structure and a large size, which is not convenient to carry around and cannot meet the user's usage needs. Summary of the invention

[0006] The purpose of the utility model is to provide an elevator maintenance anti-fall rod. The present application can form a stable structure to stabilize the locking and fixing holding device at the corner of the elevator door through the vertical distribution of the support rod and the square tube, and also has a storage structure that can rotate and displace the support rod to be stored in the storage groove, and then completely store the telescopic rod into the square tube, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator maintenance anti-fall rod, including a connecting shaft, both ends of the connecting shaft are fixedly connected with square tubes, a notch is formed at the connecting shaft between the two square tubes, the interior of the square tube is designed as a hollow structure, and the two ends are designed as open structures, a telescopic rod is movably connected to the opening at one end of the square tube away from the connecting shaft, and a support rod is arranged at the lower end of the telescopic rod, and a rotating assembly is arranged between the telescopic rod and the support rod.

[0008] Preferably, a storage groove is formed on the lower end surface of the telescopic rod, and the storage groove matches the support rod.

[0009] Preferably, the rotating assembly comprises a sleeve fixedly connected in the receiving groove, and a rotating shaft is rotatably connected inside the sleeve.

[0010] Preferably, a displacement groove is provided at a position on the upper end surface of the support rod corresponding to the rotating shaft, and the top of the rotating shaft is fixedly connected to the displacement groove.

[0011] Preferably, the rotating shaft is designed in a T-shaped structure and matches with the sleeve.

[0012] Preferably, engaging teeth are fixedly connected to the outside of the rotating shaft at equal distances, and an engaging groove matching the engaging teeth is provided at the position where the rotating shaft passes through the upper end surface of the sleeve.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The present application forms a stable structure by vertically distributing the support rod and the square tube to stabilize the clamping and fixing device at the corner of the elevator door, and also has a storage structure that can rotate and displace the support rod into the storage groove, and then completely store the telescopic rod into the square tube;

[0015] 2. The movable connection between the square tube and the telescopic rod makes it convenient for the user to adjust the overall length of the device according to the width of the elevator door on site, and the present application has a simple structure, is easy to carry and transport, and is convenient for users to use.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 5 , the utility model provides a technical solution:

[0026] The elevator maintenance anti-fall rod includes a connecting shaft 1, and is characterized in that: both ends of the connecting shaft 1 are fixedly connected with square tubes 2, a notch is formed at the connecting shaft 1 between the two square tubes 2, the interior of the square tube 2 is designed as a hollow structure, and the two ends are designed as open structures, a telescopic rod 7 is movably connected to the opening at one end of the square tube 2 away from the connecting shaft 1, and a support rod 3 is arranged at the lower end of the telescopic rod 7, and a rotating component 6 is arranged between the telescopic rod 7 and the support rod 3.

[0027] Specifically, a receiving groove 5 is formed on the lower end surface of the telescopic rod 7 , and the receiving groove 5 matches the supporting rod 3 .

[0028] Specifically, the rotating assembly 6 includes a sleeve 10 fixedly connected to the receiving groove 5, and the interior of the sleeve 10 is rotatably connected to the rotating shaft 9.

[0029] Specifically, a displacement groove 8 is provided on the upper end surface of the support rod 3 at a position corresponding to the rotating shaft 9 , and the top of the rotating shaft 9 is fixedly connected to the displacement groove 8 .
