DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example

[0020] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0021] A rotating handrail mechanism for a wheelchair area of ​​a bus comprises a handrail body 1, a rotating sleeve 2 is rotatably connected to the outer side of the handrail body 1, and a column handrail rod 3 is arranged at one end of the rotating sleeve 2 away from the handrail body 1, and further comprises:

[0022] The rotating assembly 4 is located on the top of the rotating sleeve 2, and the rotating assembly 4 is used to drive the handrail body 1 to rotate;

[0023] The limiting component 5 is located at one end of the armrest body 1 close to the rotating sleeve 2, and the limiting component 5 is used to connect the armrest body 1.

[0024] Furthermore, the rotating component 4 is composed of a sleeve 6, a rotating rod 7, a shell 8, a spiral groove 9 and a sliding block 10. The sleeve 6 is located at the top of the rotating sleeve 2, the rotating rod 7 is rotatably connected to the inside of the sleeve 6, the shell 8 is located on the outside of the rotating rod 7, the spiral groove 9 is opened on the outside of the rotating rod 7, and the sliding block 10 is fixedly connected to the inside of the shell 8 and close to one end of the spiral groove 9. When the armrest body 1 needs to be stored, the armrest body 1 can be rotated by the rotating component 4 to prevent standing passengers from entering the wheelchair area when there is no disabled person using the wheelchair area, and to have a certain impact on the passability of the passageway in the vehicle.

[0025] Among them, the rotating rod 7 passes through the sleeve 6 and is fixedly connected to the armrest body 1. The sleeve 8, the sleeve 6 and the rotating rod 7 are all slidably connected. The rotating rod 7 is fixedly connected to the armrest body 1. When the sleeve 8 drives the rotating rod 7 to move, the rotating rod 7 can drive the armrest body 1 to rotate, so that it can be stored. When the wheelchair area is not used by disabled people, it is convenient for standing passengers to enter the wheelchair area, preventing a certain impact on the passability of the passage in the vehicle.

[0026] Secondly, the internal structure size of the spiral groove 9 is designed to correspond to the external structure size of the sliding block 10. The housing 8 is connected to the spiral groove 9 through the sliding block 10. The sliding block 10 is rotatably connected to the end of the spiral groove 9 close to the spiral groove 9 with a ball 11. When the sliding block 10 is displaced inside the spiral groove 9, the ball 11 can increase the smoothness of the displacement of the sliding block 10 inside the spiral groove 9, so that the rotating rod 7 can rotate better. Pressing the housing 8 drives the sliding block 10 to move, so that the sliding block 10 can be displaced inside the spiral groove 9, and the spiral groove 9 can drive the rotating rod 7 to rotate, so that the armrest body 1 can rotate.

[0027] Furthermore, a first compression spring 12 is provided inside the sleeve 8 and at the top of the rotating rod 7, and fixed grooves 13 are provided on the outside of the rotating rod 7 and at both ends of the spiral groove 9. Two groups of elastic limit blocks are provided inside the fixed groove 13, and the fixed groove 13 is connected to the sliding block 10 through the elastic limit blocks. When the armrest body 1 is in use, the sleeve 8 is driven to move by the first compression spring 12, so that the sliding block 10 can move to the inside of the fixed groove 13 at the top of the rotating rod 7, and it is limited in the inside of the fixed groove 13 by the elastic limit blocks, and cooperates with the sliding connection between the sleeve 8 and the sleeve 6 to prevent the handrail body 1 from being rotated by the relative force when the user uses the armrest body 1, thereby driving the rotating rod 7 to rotate.

[0028] Furthermore, the limiting assembly 5 is composed of a clamping block 14 and a second compression spring 15. Both sets of clamping blocks 14 are slidably connected to the interior of the armrest body 1 and close to one end of the rotating sleeve 2. The second compression spring 15 is fixedly connected to the outer side of the clamping block 14 and is located at one end inside the armrest body 1. When the armrest body 1 is in use, the armrest body 1 can be limited by the limiting assembly 5 to prevent the armrest body 1 from being offset, which affects its use.

[0029] Furthermore, two groups of clamping grooves are provided at one end of the rotating sleeve 2 close to the clamping block 14, and the internal structure size of the clamping groove is designed to correspond to the external structure size of the clamping block 14. The second compression spring 15 is connected to the clamping groove through the clamping block 14. When the armrest body 1 is in use, the second compression spring 15 drives the clamping block 14 to move, and moves the clamping block 14 to the inside of the clamping groove, so that the armrest body 1 can be limitedly connected with the rotating sleeve 2 to prevent the armrest body 1 from being offset, which affects the use. When the armrest body 1 needs to be stored, the armrest body 1 is rotated, and the end of the clamping block 14 away from the armrest body 1 is designed with a semicircular structure, which drives the clamping block 14 to move, so that the clamping block 14 can be moved out from the inside of the clamping groove.

[0030] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the armrest body 1 needs to be stored, the sleeve shell 8 is pressed to drive the sliding block 10 to move, so that the sliding block 10 can move inside the spiral groove 9, and the spiral groove 9 can drive the rotating rod 7 to rotate, so that the armrest body 1 can rotate. When the wheelchair area is not used by disabled people, it is convenient for standing passengers to enter the wheelchair area to prevent the passability of the vehicle passage from being affected to a certain extent. When the armrest body 1 is in use, the sleeve shell 8 is driven to move by the first compression spring 12, so that the sliding block 10 can move to the top of the rotating rod 7. The inside of the fixing groove 13 is limited in the fixing groove 13 by an elastic limiting block, and the sliding connection between the sleeve shell 8 and the sleeve 6 is cooperated to prevent the user from rotating the armrest body 1 under the relative force when using the armrest body 1, driving the rotating rod 7 to rotate, and at the same time cooperating with the second compression spring 15 to drive the clamping block 14 to move, and move the clamping block 14 to the inside of the clamping groove, so that the armrest body 1 can be connected with the rotating sleeve 2 for limiting position, further preventing the armrest body 1 from being offset, resulting in affecting the use. Compared with the existing wheelchair area armrests, the utility model can improve the overall practicality of the wheelchair area armrests through design.
