specific Embodiment approach

[0012] The retractable grasping device used on the public transportation tool of the present invention, its preferred embodiment is:

[0013] It includes a gripping handle and a belt. A rotating built-in spring device is provided inside the gripping handle. The rotating built-in spring device includes a hollow cylindrical body with an open left end and a closed right end. The left end of the hollow cylindrical body is provided with a button. The interior of the hollow column is provided with a built-in spring, one end of the built-in spring is fixedly connected to the right end of the hollow column, and the other end of the built-in spring is fixedly connected to the button;

[0014] The hollow cylindrical body is flexibly connected to the grasping handle, the button is flexibly connected to the hollow cylindrical body, a positioning device is arranged between the button and the grasping handle, and the hollow cylindrical A return spring is provided between the bottom right en...

specific Embodiment

[0020] Such as figure 1 As shown, it includes grip handle 01, button 02, rotating internal spring device 03 (including hollow cylinder 33, internal spring 31, external gear 22, etc.), ball bearings 11 and 12, internal gear 21, return spring 32, left-handed cover 41 and right end cap 42, belt 04 etc., be provided with positioning device 23 between button 02 and left-handed cap 41. One end of the belt 04 is fixed on the handle bar 05 in the car, and the other end is wound on the rotating inner spring device 03, the outer gear 22 of the rotating inner spring device 03 engages with the inner gear 21, and the inner spring 31 of the rotating inner spring device 03 One end of the belt is connected to the button 02. During the elongation and shortening process of the belt 04, the rotating internal spring device 03 rotates but the button 02 does not rotate, so that the spring 31 rotates together with the rotating internal spring device 03 to store elastic potential energy;

Abstract

The invention discloses a stretchable grabbing device for public transport means. A grabbing handle is internally provided with a rotary built-in spring device which comprises a hollow cylindrical body. A button is arranged at the left end of the hollow cylindrical body and a built-in spring is arranged inside the hollow cylindrical body. One end of the built-in spring is connected fixedly with the right end of the hollow cylindrical body while the other end of the built-in spring is fixedly connected with the button. The hollow cylindrical body is connected with the grabbing handle moveably. The button is connected with the hollow cylindrical body moveably. A positioning device is arranged between the button and the grabbing handle. A restoring spring is arranged between the bottom at the right end of the hollow cylindrical body and the grabbing handle. An outer gear is arranged at the right end of the hollow cylindrical body and the grabbing handle is provided with an inner gear corresponding to the outer gear. One end of a belt is winded on the hollow cylindrical body. The stretchable grabbing device for public transport means can be suspended and adjusted in height according to height or degree of comfort of a user so as to alleviate the feeling of fatigue of the user and reduce unnecessary accidents, and increase the comfort and safety of public transport means.

Description

technical field [0001] The invention relates to a built-in accessory of a public vehicle, in particular to a retractable grasping device used on a public vehicle. Background technique [0002] The suspension height of the gripping device of existing buses, subways, etc. is fixed, and the suspension height is determined according to the average height of the crowd. However, this height is very inconvenient for people with short stature, and it is easy to cause user fatigue, especially when the driving distance is long or relatively bumpy. Contents of the invention [0003] The object of the present invention is to provide a retractable gripping device for public transportation that can adjust the suspension height according to the user's height or comfort level, and is convenient to use, safe and comfortable. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The retractable grasping device used on public transpor...
