Description

Technical Field

[0001] This utility model relates to the field of elevator car handrails, and more particularly to a telescopic elevator car handrail. Background Technology

[0002] Retractable elevator car handrails are an innovative elevator safety aid designed to improve the convenience and safety of elevator passengers, especially when used by the elderly, disabled, or passengers requiring additional support.

[0003] In existing elevator cars, handrails are usually fixed to the side walls of the car with bolts to provide auxiliary support for passengers.

[0004] However, existing fixed handrails are usually fixed tube frames, which cannot be extended or adjusted when used by the elderly, disabled or passengers who need extra support, resulting in passengers not being able to get comfortable support. Therefore, a telescopic elevator car handrail is proposed to solve the above problems. Utility Model Content

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up a handrail, a telescopic rod, a limiting groove, a limiting spring, a limiting rod, a limiting block, and a mounting plate, when it is necessary to extend the handrail to the middle of the car, the limiting rod is manually pressed to drive the limiting block to release the limiting position. Then, the handrail is moved to slide on the outer wall of the telescopic rod to the desired position. After releasing the limiting rod, the limiting spring will cause the limiting block to spring back into the corresponding limiting groove and engage, thereby realizing the rapid adjustment of the extension distance of the handrail and providing different usage needs for passengers.

[0023] 2. In this utility model, by setting up an installation plate, a telescopic rod, a return spring, a fixed rod, a fixed block, and a fixed groove, when passengers of different heights use the handrail, they can manually pull the fixed rod to release the fixed block from its limit position, and then manually raise or lower the handrail to the required height along the hinge of the installation plate. Afterwards, they can push the limit rod inward to make the fixed block engage with the corresponding fixed groove, thereby changing the angle of the handrail to accommodate passengers of different heights.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a telescopic elevator car handrail, including a handrail 1, which is a conventional elevator car handrail used to provide auxiliary support for passengers. Telescopic rods 2 are snapped onto the inner walls of both ends of the handrail 1. The telescopic rods 2 slide along the inner wall of the handrail 1, changing the distance between them through a limiting mechanism. A mounting plate 7 is hinged to the end of the telescopic rod 2, with holes on the outside of the mounting plate 7 for installation inside the elevator car using screws. A limiting rod 5 is elastically connected to the inner wall of the end of the handrail 1 via a limiting spring 4. The limiting rod 5 extends to a limiting block 6 at the top of the handrail 1 for easy manual release of the limiting position. A limiting block 6 is fixedly connected to the bottom of the limiting rod 5, and the limiting block 6 engages with a limiting groove 3 to restrict the handrail. 1. The telescopic rod 2 moves with the support rod 2. A limiting groove 3 is opened on the top of the outer wall of the telescopic rod 2. Several sets of limiting grooves 3 are provided for multiple locking limiting blocks 6 to change the distance between the support rod 1 and the telescopic rod 2. One end of the limiting spring 4 is fixedly connected to the inner wall of the end of the support rod 1, and the other end of the limiting spring 4 is fixedly connected to the upper surface of the bottom end of the limiting rod 5. Through the opposing pressing force between the limiting spring 4 and the support rod 1, the limiting block 6 is always locked on the inner wall of the limiting groove 3 without being affected by external force. The limiting rod 5 is slidably connected to the inner wall of the support rod 1 and the inner wall of the telescopic rod 2. The limiting block 6 is locked on the inner wall of the limiting groove 3 and slidably connected to the inner wall of the telescopic rod 2.

[0033] Reference Figures 4-5A fixing rod 9 is elastically connected to the inner wall of the mounting plate 7 via a return spring 8. The fixing rod 9 extends the fixing block 10 to the outer side of the inner side of the mounting plate 7, facilitating manual release of the limit and ensuring stable lateral movement of the fixing block 10. A fixing block 10 is fixedly connected to the bottom end of the fixing rod 9. The fixing block 10 is rectangular and is used to engage with the fixing groove 11 to restrict the rotation of the telescopic rod 2. The outer wall of the end of the telescopic rod 2 has a fixing groove 11, which is provided in several sets for multiple engagements with the fixing block 10 to change the extension. The angle between the retractable rod 2 and the support rod 1 is such that one end of the return spring 8 is fixedly connected to the inner wall of the mounting plate 7, and the other end of the return spring 8 is fixedly connected to the bottom end of the fixed rod 9. Through the opposing pressing force between the return spring 8 and the mounting plate 7, the fixed block 10 is always locked onto the inner wall of the fixed groove 11 without being affected by external force. The fixed rod 9 is slidably connected to the inner wall of the mounting plate 7, the fixed block 10 is slidably connected to the inner wall of the mounting plate 7, and the fixed block 10 is locked onto the inner wall of the fixed groove 11.

[0034] Working principle: When it is necessary to extend the handrail 1 to the middle of the car, the limit rod 5 is pressed manually to drive the limit block 6 to disengage from the limit groove 3 and release the limit. Then, the handrail 1 is moved to slide on the outer wall of the telescopic rod 2 to the desired position. After releasing the limit rod 5, the limit block 6 is rebounded into the corresponding limit groove 3 by the limit spring 4 and locked. This realizes the quick adjustment of the extension distance of the handrail 1, thereby providing different usage needs for passengers and improving the convenience and comfort of use.

[0035] When passengers of different heights use the handrail 1, the fixed block 10 is disengaged from the fixed groove 11 by manually pulling the fixed rod 9 to release the limit. Then, the handrail 1 is manually raised or lowered to the required height along the hinge of the mounting plate 7. After that, the fixed rod 9 is pushed inward to make the fixed block 10 snap into the corresponding fixed groove 11, so as to quickly change the angle of the handrail 1 for passengers of different heights and improve the adaptability of the handrail.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
