Description
Technical Field
[0001] The utility model relates to the technical field of seat installation, in particular to a seat installation component of a rail transit vehicle. Background Art
[0002] Rail transit is one of the important modes of transportation for people at present. Rail transit usually refers to transportation modes such as subways. In order to improve people's riding experience, seats are generally set on both sides of the subway car. However, since subway cars are different from train cars and lack luggage racks, most of the seats in subway cars are currently installed close to the car walls, and the space under the seats is used for passengers to place luggage.
[0003] This results in the seats in rail transit subway cars being basically fixed to the car walls and the support plates on both sides using angle irons. With this installation method, when passengers sit on the seats, the main load-bearing point of the seats is the range of the angle iron fixed installation. In long rows of seats, the middle area cannot get effective support. Therefore, the common way for seats in subway cars to be damaged is that the middle part of the long row of seats sinks and bends. Therefore, relying solely on angle irons for installation will reduce the service life of the seats and also pose certain safety hazards.
[0004] Therefore, it is necessary to provide a new seat installation assembly for rail transit vehicles to solve the above technical problems. Utility Model Content

Figure 3 As shown, the two avoidance holes 17 communicate with the limiting grooves 16, and the two avoidance holes 17 are respectively close to the front and rear sides of the limiting grooves 16. A clamping column 24 is movably installed on the outer wall of one side of any one extension plate 20. One end of the clamping column 24 extends into the corresponding avoidance hole 17.

One end of the threaded rod 10 passes through the rotating sleeve 14 and the threaded cylinder 15, and the threaded rod 10 is threadedly connected to the inner wall of the threaded cylinder 15. During actual use, it is necessary to limit the threaded rod 10 so that the threaded rod 10 cannot rotate on its own and can only slide horizontally.

[0027] A clamping cylinder 7 is fixedly installed on the horizontal plate 6, and a pin rod 8 is movably installed on the outer wall of the clamping cylinder 7.

[0028] The working principle of the seat installation assembly of the rail transit vehicle provided by the utility model is as follows:
[0029] First, when using the present device to install seats in a rail transit subway car, the support plate 1 can be first fixed to the car wall by means of two fixing anchor bolts 3 on the support plate 1, and multiple support plates 1 can be installed on the car wall, while making the fixing plates 2 on the multiple support plates 1 at the same height. Then, the seat can be placed on the multiple fixing plates 2, and preparations can be made for connection between the seat bottom and the fixing plates 2.
[0030] When connecting, the staff can press the two spring plates 18 on the first fixing plate 2 close to the support plate 1. The two spring plates 18 are gradually flattened after being stressed, so that the two abutment columns 19 enter the corresponding avoidance holes 17, thereby pushing out the two clamping columns 24 located in the two avoidance holes 17. When the two clamping columns 24 are pushed out, the two sliding plates 22 are also stressed, so that the two springs 23 are in a compressed energy storage state. At this time, the staff can pull the second fixing plate 2 (combined with Figure 1 As shown, the fixing plate 2 close to the supporting plate 1 is the first one, and the subsequent ones are similar), so that the two extension plates 20 located in the first fixing plate 2 slide out, and at this time, the two holding columns 24 are respectively supported on the inner walls of the two limiting grooves 16 by the effect of the two springs 23, and when the two holding columns 24 move to another avoidance hole 17, the two holding columns 24 enter the two avoidance holes 17 respectively under the effect of the springs 23, and at this time the second fixing plate 2 is stretched to the maximum distance. According to the above method, multiple fixing plates 2 can be spread out in a linear array, and the installation and fixation of the seat can be completed by connecting the multiple fixing plates 2 and the positioning plates 4 to the bottom of the seat through the fixing anchor bolts 3.
[0031] At the same time, the staff can also swing the rotating cylinder 9. After rotating the rotating cylinder 9 to a suitable angle, they can hold the rotating sleeve 14 and rotate it. The rotation of the rotating sleeve 14 will drive the threaded cylinder 15 to rotate, thereby driving the threaded rod 10 to extend horizontally from the rotating cylinder 9, thereby changing the position of the connecting frame 11. Through continuous adjustment, the connecting frame 11 is rotated to a vertical state to correspond to the clamping cylinder 7. At this time, the anchor rod 12 can be inserted, and the pin rod 8 is used to cross the clamping cylinder 7 to limit the anchor rod 12. In this way, the connecting frame 11 is connected to the cross plate 6, and the entire rotating cylinder 9 and the threaded rod 10 are inclined at a certain angle, which has a further reinforcement effect.
[0032] Compared with the related art, the seat installation assembly for rail transit vehicles provided by the utility model has the following beneficial effects:
[0033] The utility model provides a seat installation component for a rail transit vehicle. During the installation of the seat in the rail transit vehicle, the limiting effect between adjacent fixing plates 2 can be quickly released by pressing the spring sheet 18, so that the fixing plates 2 can be evenly arranged at the bottom of the seat, increasing the support range and making the force range of the seat more uniform. At the same time, the inclined setting of the rotating cylinder 9 and the threaded rod 10 can further play a supporting effect, thereby improving the service life of the seat and increasing the safety of the seat to a certain extent.
