Technical Field

[0001] The utility model relates to the technical field of interior equipment of subway vehicles, in particular to a subway seat convenient for maintenance. Background Technique

[0002] The subway is a rapid mass urban rail transit mode developed gradually along the form of the ground railway system, and its lines are usually laid in underground tunnels. Some are outside the city center and are laid from underground to the ground or on viaducts. With the rapid development of the economy, green travel is accepted by more and more people. More and more people choose public transportation facilities such as buses, bicycles, and subways instead of cars. As the main means of transportation in the city, the subway is very convenient and fast.

[0003] At present, the existing urban rail subway seats are generally designed with multiple seats in a row, but they are all integrally formed and fixed structures. When a single seat is damaged, the entire row of seats needs to be replaced, resulting in waste. Content of the Utility Model

[0004] The purpose of the utility model is to address the deficiencies of the prior art and provide a subway seat convenient for maintenance, so as to solve the problem that the existing urban rail subway seats are generally designed with multiple seats in a row, but they are all integrally formed and fixed structures.

[0025] Embodiment

[0026] Refer to Figures 1 - 4, a subway seat convenient for maintenance, comprising a seat base 1 and a plurality of seats 2 detachably arranged on the seat base 1. The seat base 1 includes a bottom plate 11 in a long strip rectangular structure. A plurality of equally spaced installation grooves 111 are opened on the top end face of the bottom plate 11. A fixing groove 112 corresponding to the installation groove 111 one by one is opened on the top end face of one side of the bottom plate 11. On the other side of the bottom plate 11, there is a support plate 12 extending along the length direction of the bottom plate 11 and perpendicular to it. A guiding groove 121 corresponding to the installation groove 111 one by one is opened on the top of the side of the support plate 12 close to the bottom plate 11. The side of the support plate 12 far from the bottom plate 11 is fixedly connected to the side wall 3 of the subway carriage.

[0027] Wherein, a linkage hole 113 is penetrated and opened on the bottom plate 11 at the bottom of the fixing groove 112. A linkage rod 114 is slidably connected in the linkage hole 113. A first limit disc 115 is arranged at the bottom of the linkage rod 114. A tension spring 116 is sleeved on the outer side of the linkage rod 114 between the first limit disc 115 and the bottom plate 11. One end of the tension spring 116 is fixedly connected to the top end face of the first limit disc 115, and the other end of the tension spring 116 is fixedly connected to the bottom end face of the bottom plate 11.

[0028] Furthermore, a bearing seat 118 is arranged on the bottom plate 11 between two adjacent fixing grooves 112. An armrest 4 in an arc structure is arranged on the bearing seat 118. One end of the armrest 4 is fixedly connected to the bearing seat 118, and the other end of the armrest 4 is fixedly connected to the side wall 3 of the subway carriage.

[0029] Furthermore, a leaning board 5 for passengers to lean on is arranged in the middle of the armrest 4 at both ends of the seat base 1.

[0030] Reference Figure 3 , the seat 2 includes a seat board 21. An installation plate 211 that fits with the installation groove 111 and a fixing seat 212 that can be inserted into the fixing groove 112 are arranged on the bottom end face of the seat board 21. A back board 22 that is matched with the seat board 21 is arranged on the side of the seat board 21 far from the fixing seat 212. The seat board 21 and the back board 22 are of an integrally formed structure. A guiding board 221 that fits with the guiding groove 121 is arranged on the top of the side of the back board 22 far from the bottom plate 11. Through the arrangement of the guiding board 221 and the guiding groove 121, the installation of the seat 2 and the seat base 1 can be guided and connected.

[0031] Among them, a driving groove 213 is formed on one side of the fixing base 212 away from the back plate 22. A driving rod 214 is slidably connected in the driving groove 213. One end of the driving rod 214 extends outside the driving groove 213 and is provided with a second limiting disc 215. The other end of the driving rod 214 is provided with a compression spring 216. One end of the compression spring 216 is fixedly connected to the inner side wall of the driving groove 213, and the other end of the compression spring 216 is fixedly connected to the driving rod 214. A locking block 217 with an L-shaped structure is fixedly connected to the bottom of the driving rod 214 near one end of the compression spring 216.

[0032] Further, a locking groove 117 into which the locking block 217 can be inserted is formed at the top of the linkage rod 114.

[0033] Furthermore, a movable groove 218 for the front-back displacement of the locking block 217 is formed in the fixing base 212. The movable groove 218 communicates with the driving groove 213. A linkage groove 219 into which the top of the linkage rod 114 can be inserted is formed on the bottom end face of the fixing base 212. The linkage groove 219 communicates with the movable groove 218.

[0034] The working principle of the present utility model:

[0035] During installation, the staff inserts the connection plate 221 on the seat 2 into the connection groove 121 on the seat base 1. During the insertion process, when the fixing base 212 at the bottom of the seat 2 approaches the fixing groove 112 on the seat base 1, the first limiting disc 115 on the seat base 1 is pulled downward to drive the linkage rod 114 to move downward. At the same time, the tension spring 116 is stretched and deformed until the top of the linkage rod 114 is completely received in the linkage hole 113 on the seat base 1. After the fixing base 212 at the bottom of the seat 2 is completely inserted into the fixing groove 112 on the seat base 1, then the second limiting disc 215 on the fixing base 212 is pushed inward to drive the driving rod 214 to move inward. At the same time, the compression spring 216 is squeezed and deformed. The first limiting disc 115 is released, and the tension spring 116 is reset under the elastic action to drive the linkage rod 114 to be inserted into the linkage groove 219 on the fixing base 212. Then the second limiting disc 215 is released, and the compression spring 216 is reset under the elastic action to drive the locking block 217 on the driving rod 214 to be inserted into the locking groove 117 on the linkage rod 114, thereby tightly locking the linkage rod 114 in the fixing base 212, making the seat 2 and the seat base 1 firmly connected. When a single seat 2 is damaged, the reverse operation above can be performed to complete the disassembly of the single seat 2.

[0036] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" 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.

[0037] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the utility model patent. It should be noted 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.
