Technical Field

[0001] This utility model belongs to the field of bus seat technology, and in particular relates to a seat cushion cover. Background Technology

[0002] Bus seat covers are components installed on bus seats to cover and protect specific parts of the seats or to achieve specific functions.

[0003] Existing seat cover panels have some drawbacks in use, such as requiring workers to use tools and numerous bolts for assembly and fixing to the seat, making the process more cumbersome and time-consuming. Therefore, we propose a new type of seat cover panel. Utility Model Content

[0004] The purpose of this utility model is to provide a seat cover to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a seat cover, comprising two fixing plates and a bus seat, and further comprising:

[0006] Two limiting plates are inserted and installed between two fixed plates. A rectangular plate and a back plate are respectively inserted and installed on both sides of the two limiting plates. A maintenance door is rotatably installed on the rectangular plate. A sliding groove is opened in the back plate. Two sliding plates are slidably installed in the sliding groove. The two sliding plates extend through the sliding groove and into the two fixed plates respectively on the side that is away from each other. The two sliding plates are respectively inserted and engaged with the two fixed plates.

[0007] A drive assembly, located within the backplate, is used to drive two sliding plates to slide.

[0008] A limiting groove is formed in the upper fixing plate, and two fixing strips are inserted and installed in the limiting groove. The tops of the two fixing strips pass through the limiting groove and extend to the outside. The bus seat is fixedly installed on the tops of the two fixing strips.

[0009] A fixing component is located within the upper fixing plate and is used to fix the positions of the two fixing strips.

[0010] In this technical solution, when installing the overall device, the lower fixed plate is first fixed to the bus with bolts. Then, two limiting plates are inserted into the lower fixed plate. Subsequently, the rectangular plate and the back plate are inserted into the two limiting plates. At the same time, the rectangular plate and the back plate are in contact with the two fixed plates. Through the set drive component, the two sliding plates can be driven to slide and move closer to each other. After the two sliding plates are completely in the sliding groove, the upper fixed plate is inserted into the rectangular plate and the back plate. Through the set drive component, the two sliding plates can be driven to slide and move away from each other. The two sliding plates are respectively inserted into the two fixed plates. The two fixed plates, two limiting plates, rectangular plate and back plate can be assembled. The operation is simple and quick.

[0011] By using the pre-installed fixing components, two fixing strips are then inserted into the upper fixing plate. The fixing components secure the two fixing strips, thus fixing the bus seat in place. This makes it easy and quick to install and fix the bus seat.

[0012] In the above technical solution, the driving component further includes:

[0013] A sliding bar is slidably installed in a sliding groove. The sliding bar has four guide grooves, and guide posts are slidably installed in each of the four guide grooves. The four guide posts are respectively fixedly connected to two sliding plates.

[0014] A plurality of fixed posts are fixedly installed on one side of the sliding bar, and a first spring fixedly installed at one end of each of the fixed posts and fixed to the inner wall of the sliding groove.

[0015] In this technical solution, the sliding bar is then pulled to slide, causing several fixed posts to slide. Simultaneously, several first springs are compressed and contracted. The sliding bar drives four guide posts to slide through four guide grooves. The four guide posts drive two sliding plates to slide and move closer to each other. After both sliding plates are fully inserted into the sliding grooves, the fixed plate located above is inserted into the rectangular plate and the back plate. Then, the sliding bar is released. Under the rebound force of the first springs, several fixed posts slide, causing the sliding bar to slide. The sliding bar drives four guide posts to slide through four guide grooves. The four guide posts drive two sliding plates to slide and move away from each other. The two sliding plates are inserted into the two fixed plates. The two fixed plates, two limiting plates, rectangular plate, and back plate can be assembled. The operation is simple and quick.

[0016] In the above technical solution, the fixing component further includes:

[0017] A sliding rod is slidably installed in a limiting groove. Four connecting rods are rotatably installed on the sliding rod. Limiting blocks are slidably installed in the limiting groove on both sides of the sliding rod. The four connecting rods are rotatably connected to two limiting blocks respectively. The two limiting blocks extend into two fixing strips on the opposite sides of each other, and the two limiting blocks are respectively inserted into the two fixing strips.

[0018] Two guide rods are fixedly installed in the limiting groove, and one end of each guide rod passes through a sliding rod. The sliding rod is slidably connected to the two guide rods, and a second spring is sleeved on each of the two guide rods.

[0019] In this technical solution, the operator pulls the sliding rod to slide, which compresses two second springs and causes them to contract. Simultaneously, the sliding rod pulls four connecting rods to rotate, and the four connecting rods pull two limiting blocks to slide and move closer to each other. When both limiting blocks have slid to the appropriate positions, two fixing strips are inserted into the upper fixing plate. Then, the sliding rod is released. Under the rebound force of the two second springs, the sliding rod slides and drives the four connecting rods to rotate. The four connecting rods compress the two limiting blocks to slide and move away from each other. The two limiting blocks are then inserted into the two fixing strips, which fixes the position of the two fixing strips. Finally, the position of the bus seat is fixed, facilitating the installation and fixing of the bus seat. The operation is simple and quick.

[0020] In the above technical solution, furthermore, the two ends of the two second springs are welded to the inner wall of the limiting groove and the sliding rod, respectively.

[0021] In this technical solution, it is ensured that both second springs can be used stably.

[0022] In the above technical solution, a fixing block is further fixedly installed on the sliding bar, one end of the fixing block passes through the sliding groove and extends to the outside, and the fixing block is slidably connected to the sliding groove.

[0023] In this technical solution, the fixed block facilitates the movement of the sliding bar by the operator.

[0024] In the above technical solution, both limiting blocks are slidably connected to the limiting groove, and the sliding strip and several fixed posts are slidably connected to the sliding groove.

[0025] In this technical solution, it is ensured that both limiting blocks can slide within the limiting groove, and that the sliding strip and several fixed posts can slide within the sliding groove.

[0026] Furthermore, in the above technical solution, a through hole is provided inside the sliding rod.

[0027] In this technical solution, it is convenient for workers to pull the sliding rod through the through hole.

[0028] The beneficial effects of this utility model are:

[0029] 1. This seat cover is first fixed to the bus with bolts using a lower fixing plate. Then, two limiting plates are inserted into the lower fixing plate. Subsequently, a rectangular plate and a back plate are inserted into the two limiting plates, with both the rectangular plate and the back plate in contact with the two fixing plates. Through a set drive component, the two sliding plates can be driven to slide and move closer to each other. After both sliding plates are fully inserted into the sliding groove, the upper fixing plate is inserted into the rectangular plate and the back plate. Through the set drive component, the two sliding plates can be driven to slide and move away from each other. The two sliding plates are respectively inserted into the two fixing plates. The two fixing plates, two limiting plates, rectangular plate, and back plate can be assembled, making the operation simple and quick.
