[0002] Handrails are typically suspended auxiliary facilities commonly found in public transportation vehicles such as buses and subway cars. They generally consist of hanging rings and handrails connecting the rings. Passengers can hold onto the handrails to maintain their balance while standing, providing support and stability during vehicle movement. They are particularly effective in preventing passengers from falling when the vehicle is turning or braking, providing convenience and safety for passengers. In addition, similar handrails may also be found in some special places such as rehabilitation training rooms to assist in rehabilitation training.

[0003] Most of the handrails commonly found on the market are designed with a fixed height, which makes it difficult to meet the needs of people of different heights and has poor applicability. In addition, the handrails are easily affected by factors such as vehicle shaking and unintentional touch by passengers, which can cause shaking and interference, potentially interfering with passengers' normal activities, occupying public space, and even colliding with passengers. Therefore, improvements are needed. To this end, an automatic reset structure for handrails is proposed. Utility Model Content

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] An automatic reset structure for a hanging handrail includes a hanging handrail body 1. A crossbar 2 is arranged directly above the hanging handrail body 1. A box 3 is arranged at the end of the crossbar 2. A motor 4 is fixedly installed inside the box 3. A slide rail 5 is provided on the crossbar 2. A bidirectional lead screw 6 is rotatably arranged inside the crossbar 2. The output shaft end of the motor 4 is fixedly installed with the end of the bidirectional lead screw 6. Symmetrical movable blocks 7 are slidably arranged on the crossbar 2 and the slide rail 5. The movable blocks 7 are threadedly connected to the bidirectional lead screw 6. A frame 8 is fixedly installed at the bottom of each movable block 7. A suspension strap 9 is provided on each frame 8. The bottom ends of the two sets of suspension straps 9 are hinged to the side of the hanging handrail body 1.

[0028] When in use, the crossbar 2 supports the entire device and provides a base for the installation of each component. The two sets of slings 9 provide support from both sides of the lifting ring body 1, keeping the lifting ring body 1 stable. Personnel can improve their body stability during movement by holding the lifting ring body 1.

[0029] When the height of the lifting ring body 1 needs to be adjusted, the motor 4 inside the box 3 is started. The output shaft of the motor 4 drives the double-acting screw 6 inside the crossbar 2 to rotate. Since the double-acting screw 6 is threadedly connected to the movable block 7, and the crossbar 2 is provided with a slide rail 5 for the movable block 7 to slide, as the double-acting screw 6 rotates, the two movable blocks 7 will slide relative to each other or away from each other along the slide rail 5 on the crossbar 2. The frame 8 fixed at the bottom of the movable block 7 moves accordingly. The sling 9 on the frame 8 pulls the lifting ring body 1 up or down, thereby realizing the adjustment of the height of the lifting ring body 1 to meet the gripping needs of people of different heights.

[0030] After the lifting ring body 1 is used up, the motor 4 is started again to make the double-sided lead screw 6 rotate. The movable block 7 drives the frame 8 and the sling 9 to rise, driving the lifting ring body 1 to automatically reset and rise to the initial state, so as to avoid the lifting ring shaking interference.

[0031] The automatic reset structure of the handrail can adjust the height of the handrail body 1, making it easy for people of different heights to hold. It is highly applicable. After use, it can drive the handrail to rise and automatically reset to the initial state, ensuring that the handrail is in a standardized and orderly state, avoiding shaking and interference, and is highly practical.

[0032] A connecting rod 10 is fixedly installed on the frame 8 by screws, and the top end of the sling 9 is hinged to the connecting rod 10.

[0033] A connecting rod 10 is fixedly installed on the frame 8 by screws, and the top of the sling 9 is hinged to the connecting rod 10, which facilitates the installation of the connecting rod 10 and the sling 9.

[0034] Flanges 11 are fixedly installed at both ends of the crossbar 2, and the box body 3 is fixedly installed to the flanges 11 by screws;

[0035] Both ends of the crossbar 2 are fixedly installed with flanges 11. The box body 3 is fixedly installed with the flanges 11 by screws. Multiple crossbars 2 and the box body 3 are connected in sequence by flanges 11 and screws, which can extend the length of the entire crossbar 2 to adapt to different sizes of carriages or installation spaces.

[0036] Both the box body 3 and the movable block 7 are circular.

[0037] Both the box 3 and the movable block 7 are designed to be circular, which can reduce injuries caused by accidental collisions.

[0038] The lifting ring body 1 is set as a ring;

[0039] The ring body 1 is designed as a ring for easy gripping.

[0040] The outer wall of the lifting ring body 1 is provided with a grip sleeve, which is made of rubber.

[0041] The outer wall of the lifting ring body 1 is equipped with a rubber grip, which can improve the stability of personnel holding the lifting ring body 1.

[0042] Working principle:

[0043] When in use, the crossbar 2 supports the entire device and provides a base for the installation of each component. The two sets of slings 9 provide support from both sides of the lifting ring body 1, keeping the lifting ring body 1 stable. Personnel can improve their body stability during movement by holding the lifting ring body 1.

[0044] When the height of the lifting ring body 1 needs to be adjusted, the motor 4 inside the box 3 is started. The output shaft of the motor 4 drives the double-acting screw 6 inside the crossbar 2 to rotate. Since the double-acting screw 6 is threadedly connected to the movable block 7, and the crossbar 2 is provided with a slide rail 5 for the movable block 7 to slide, as the double-acting screw 6 rotates, the two movable blocks 7 will slide relative to each other or away from each other along the slide rail 5 on the crossbar 2. The frame 8 fixed at the bottom of the movable block 7 moves accordingly. The sling 9 on the frame 8 pulls the lifting ring body 1 up or down, thereby realizing the adjustment of the height of the lifting ring body 1 to meet the gripping needs of people of different heights.

[0045] After the lifting ring body 1 is used up, the motor 4 is started again to make the double-sided lead screw 6 rotate. The movable block 7 drives the frame 8 and the sling 9 to rise, driving the lifting ring body 1 to automatically reset and rise to the initial state, so as to avoid the lifting ring shaking interference.

[0046] The automatic reset structure of the handrail can adjust the height of the handrail body 1, making it easy for people of different heights to hold and making it highly applicable. After use, it can drive the handrail to rise and automatically reset to the initial state, ensuring that the handrail is in a standardized and orderly state, avoiding shaking and interference, and making it highly practical.
