Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3In this embodiment of the utility model, the seat frame with positioning and clamping function that can be quickly disassembled at different positions includes a long track 1, a seat frame side plate 3, a connecting plate 10, and a connecting rod 11. The bottom frame side plate has a vertical "U"-shaped structure. Two upper rectangular tubes 5 and two lower rectangular tubes 6 are welded between the two bottom frame side plates. A trolley 2 is fixedly connected to the bottom of the bottom frame side plate. Two sliding sleeves 7 are threadedly connected to the middle of the trolley 2. A first spring pin 8 and a second spring pin 9 are slidably connected in the two sliding sleeves 7 respectively. A spring 14 is provided between the first spring pin 8, the second spring pin 9 and the sliding sleeve 7. A connecting plate 10 is provided in the groove in the middle of the first spring pin 8 and the second spring pin 9. The top of the connecting plate 10 is rotated with the first spring pin 8. The second spring pin 9 has a bolt at its top, and the connecting plate 10 is located below the bolt. The other ends of the two connecting plates 10 are fixedly connected by a connecting rod 11. A long track 1 is provided below the trolley 2. The long track 1 has an inverted "T"-shaped groove inside. Multiple circular positioning holes 18 are evenly distributed on the top of the long track 1. A positioning post 13 is provided at the bottom of the second spring pin 9. The positioning post 13 is slidably connected to the positioning hole 18. Short sliders 15 and long sliders 16 are respectively provided at the center of the bottom two sides of the trolley 2. Both short sliders 15 and long sliders 16 are slidably connected to the grooves in the long track 1. The seat frame position is easy to adjust, the operation is simple, the sliding is smooth and stable, and it is suitable for various models with a wide range of applications.

[0022] Both the short slider 15 and the long slider 16 are T-shaped structures. The short slider 15 is located on the side of the trolley 2 near the connecting rod 11. Both the short slider 15 and the long slider 16 are fixedly connected to the seat frame side plate 3 by bolts installed from the bottom, which facilitates the disassembly and installation of the trolley 2 and makes it easy to use.

[0023] Among them, the top of the groove of the long track 1 is provided with a long strip-shaped disassembly groove 20 on the side where the connecting rod is located. The width of the disassembly groove 20 is equal to the width of the short slider 15 and the long slider 16. The seat frame side plate 3 and the trolley 2 can be removed from the disassembly groove 20 as a whole using the disassembly groove 20. It is convenient to use and simple to operate.

[0024] The top of the connecting plate 10 is provided with an inclined sliding groove 12. The bolt on the top of the first spring pin 8 is slidably connected to the sliding groove 12. By changing the relative position of the connecting plate 10 and the first spring pin 8, it is easier to lift the connecting rod 11 to release the locking of the positioning post 13 at the bottom of the second spring pin 9, making it easier to use.

[0025] Among them, the bottom sides of the seat frame side plate 3 are provided with "L"-shaped lower mounting plates 4. The horizontal side of the lower mounting plate 4 is threadedly connected to the mounting bolts of the short slider 15 and the long slider 16. The vertical side of the lower mounting plate 4 is welded to both ends of the lower rectangular tube 6 to avoid interference and improve the structural strength.

[0026] Among them, pulleys 17 are rotatably connected to the inside of both ends of the trolley 2. The width of the pulleys 17 is greater than the width of the top of the groove of the long track 1. The pulleys 17 are slidably connected to the top of the long track 1 to reduce the friction between the trolley 2 and the long track 1, ensuring smooth and noiseless long-distance movement.

[0027] The long track 1 has mounting holes 19 at both ends of the groove bottom. The mounting holes 19 correspond to the positioning holes 18 at both ends. The long track 1 is fixedly connected to the vehicle by bolts passing through the mounting holes 19, which facilitates the fixed connection of the long track 1 and makes it easy to use.

[0028] The working principle of this utility model is as follows: First, the long track 1 is fixedly connected to the vehicle by bolts through the mounting hole 19. The long track 1 is made of aluminum profile with a thickness of 14mm to avoid installation interference caused by track thickness limitations, while ensuring that the long track 1 has sufficient rigidity and load-bearing capacity. The long slider 16 and short slider 15 at the bottom of the trolley 2 are sent into the long track 1 from the disassembly groove 20 position of the long track 1, so that the long slider 16 slides with the short slider 15 and the groove of the long track 1, which facilitates the disassembly and installation of the seat frame, making it convenient to use and easy to maintain. When adjusting the position of the trolley 2, the connecting rod 11 is pushed first to make the sliding groove 12 on the connecting plate 10 slide with the bolt at the top of the first spring pin 8, which facilitates lifting. Link 11 saves energy. Lifting link 11 causes the connecting plate 10 to rotate and connect with the bolt at the top of the first spring pin 8. Under the action of the connecting plate 10, the second spring pin 9 is lifted, and the positioning post 13 at the bottom of the second spring pin 9 is unlocked from the positioning hole 18 of the long track 1. This pushes the trolley 2 to move, thereby adjusting the position of the seat frame side plate 3. During this process, the pulley 17 of the trolley 2 slides and connects with the top of the long track 1, reducing friction and making the seat move smoothly and quietly. When the position is adjusted to a suitable position, press down link 11. The second spring pin 9 slides down under the action of spring 14, so that the positioning post 13 slides and connects with the nearest positioning hole 18, thereby locking the position of the seat frame side plate 3. The adjustment is convenient and the operation is simple.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
