[0021] Embodiment

[0022] Reference Figures 1 - 5, A subway grab bar with high adaptability, including a grab bar body 1. The grab bar body 1 includes a fixing plate 101. On both sides of the bottom of the fixing plate 101, connecting columns 102 are symmetrically arranged. Between the bottoms of the two connecting columns 102, there is a first handrail 103. The fixing plate 101, the two connecting columns 102 and the first handrail 103 are of an integrally formed structure. When a passenger with a relatively tall height uses the grab bar body 1, they can directly hold the first handrail 103 on the grab bar body 1 for use. On the bottom end face of the connecting column 102, a receiving cavity 104 is opened. Inside the receiving cavity 104, there is a transmission frame 105 in a hollow rectangular structure. In the middle of the transmission frame 105, a transmission gear 106 is rotatably connected. Inside the transmission frame 105, there is a first transmission tooth plate 107 meshing with the transmission gear 106. Between the bottoms of the two first transmission tooth plates 107, there is a second handrail 108. Outside the transmission frame 105, there is a second transmission tooth plate 109 installed on the inner side wall of the receiving cavity 104 and meshing with the transmission gear 106. When a passenger with a relatively short height uses the grab bar body 1, by holding the second handrail 108 on the grab bar body 1 and pulling it downward, the height of the second handrail 108 can be reduced, thereby reducing the height of the grab bar body 1, which is convenient for passengers with a relatively short height to hold the grab bar body 1 and keep their body stable.

[0023] In a further optimized solution, on the top side of the first transmission tooth plate 107 close to the transmission frame 105, a first stop plate 110 is fixedly connected. On the bottom side of the second transmission tooth plate 109 close to the transmission frame 105, a second stop plate 111 is fixedly connected. And both the first stop plate 110 and the second stop plate 111 are located inside the transmission frame 105. Through the settings of the first stop plate 110 and the second stop plate 111, the movement of the first transmission tooth plate 107 and the transmission frame 105 can be limited.

[0024] Furthermore, on the top of the first stop plate 110, a first tension spring 112 with one end connected to the inner top end face of the receiving cavity 104 is fixedly connected. On the top of the transmission frame 105, a second tension spring 113 with one end connected to the inner top end face of the receiving cavity 104 is fixedly connected. Through the settings of the first tension spring 112 and the second tension spring 113, when a passenger does not use the second handrail 108 on the grab bar body 1, the second handrail 108 can automatically contract and reset, and after the grab bar body 1 returns to the highest position, it does not occupy too much space and does not affect other passengers.

[0025] Among them, on the top of the fixing plate 101, there is a fixing sleeve 114. Between the fixing sleeve 114 and the fixing plate 101, there is a connecting belt 115.

[0026] The working principle of the present utility model:

[0027] When a passenger with a relatively tall height uses the hanging ring body 1, they can directly hold the first handrail 103 on the hanging ring body 1 for use. When a passenger with a relatively short height uses the hanging ring body 1, they hold the second handrail 108 on the hanging ring body 1 and pull it downwards, thereby driving the first transmission gear plate 107 to move downwards. At the same time, the transmission gear 106 meshing with the first transmission gear plate 107 starts to rotate. Since the transmission gear 106 also meshes with the second transmission gear plate 109, the transmission frame 105 is driven by the first transmission gear plate 107 connected to it to move downwards synchronously. At the same time, the first tension spring 112 and the second tension spring 113 undergo elastic deformation. At this time, the height of the second handrail 108 is reduced, thereby reducing the height of the hanging ring body 1, facilitating a passenger with a relatively short height to hold the hanging ring body 1 and keep their body stable. When a passenger with a relatively short height does not use the hanging ring body 1, they release the second handrail 108, and the first tension spring 112 and the second tension spring 113 reset under the elastic action, driving the first transmission gear plate 107 and the transmission frame 105 to move upwards. The transmission gear 106 starts to rotate in the opposite direction to when it is stretched until the first transmission gear plate 107 and the transmission frame 105 contract into the accommodation cavity 104 on the hanging ring body 1.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
