[0002] In the field of bicycle design and manufacturing, a frame folder is a key component that allows users to fold the bicycle frame to reduce its size for easy carrying and storage. However, the traditional bicycle frame folder design has significant limitations, which mainly come from its fixed installation method.

[0003] Traditional frame folders are usually fixed to specific positions of the frame by direct welding. Although this design ensures a firm connection between the folder and the frame, it also brings significant maintenance and replacement problems. Once the folder is damaged due to long-term use, accidental collision or other reasons, the user will face the dilemma of being unable to disassemble and replace the folder alone. This is because the connection between the folder and the frame is achieved by welding.

And they are connected by fixing bolts 20; connecting parts 30 are respectively provided at the positions corresponding to the other end surface of the left socket 21 and the other end surface of the right socket 22, and are connected by a hinge seat 40, and through holes 50 are symmetrically opened on the surface of the connecting part 30; the inner support component 23 is arranged on the inner wall of the left socket 21; the limiting component 24 is symmetrically arranged on the surface of the left frame 11, and the limiting seat 25 is symmetrically fixedly connected to the surface of the right frame 12 and corresponds to the position of the limiting component 24; one end of the limiting component 24 is connected to one end of the inner support component 23, and the other end of the limiting component 24 passes through the through hole 50 into the interior of the limiting seat 25.

[0029] It should be noted that the outer diameter of the connecting portion 30 is larger than the outer diameters of the left frame 11 and the right frame 12 .

[0030] Specifically, when in use, first connect the two groups of connecting parts 30 through the hinge seat 40, and then fit the two groups of connecting parts 30 together, and then insert one end of the left socket 21 and one end of the right socket 22 into the left frame 11 and the right frame 12 respectively until they abut against the surface of the connecting part 30, and then connect the fixing bolt 20 with the fixing hole 10, so that the left socket 21 and the right socket 22 are fixed on the left frame 11 and the right frame 12 respectively. After fixing, loosen the fixing screw 243 in the limiting assembly 24 so that the slide seat 242 in the limiting assembly 24 can move on the surface of the left frame 11, and then move the slide seat 242 to the side of the limiting seat 25, and the movement of the slide seat 242 synchronously drives the fixing screw in the limiting assembly 24 243 and the limiting rod 244 move, the movement of the fixed screw 243 synchronously drives the threaded cylinder 233 and the inner support seat 231 in the inner support assembly 23 to move, the movement of the inner support seat 231 allows one end of it to enter the right socket 22, thereby supporting the inside of the right socket 22, and the movement of the limiting rod 244 allows one end of it to pass through the through hole 50 and be inserted into the limiting seat 25, and then the limiting rod 244 is rotated to make the limiting rod 244 and the inner wall of the limiting seat 25 screwed and fixed, thereby connecting the left frame 11 and the right frame 12, with good use effect. When folding, the limiting rod 244 is rotated to separate it from the inner wall of the limiting seat 25, and then the slide seat 242 is moved, and the inner support seat 231 and the limiting rod 244 are linked to reset.

[0031] In one embodiment of the present invention, Figure 1-Figure 2 As shown, an elastic clamp 60 and a clamping hole 70 are respectively provided at a position where one end surface of the left socket 21 corresponds to the inner wall position of the left frame 11 and at a position where one end surface of the right socket 22 corresponds to the inner wall position of the right frame 12. The elastic clamp 60 is located on the inner side of the fixing hole 10, and the elastic clamp 60 is clamped and fixed with the clamping hole 70.

[0032] Specifically, the elastic clamp 60 and the clamp hole 70 are designed to facilitate quick connection between the left socket 21 and the left frame 11 and between the right socket 22 and the right frame 12, and to quickly and accurately position the fixing hole 10, so as to facilitate the connection and use of the fixing bolt 20.

[0033] In one embodiment of the present invention, Figure 2-Figure 3 As shown, the inner support assembly 23 includes an inner support seat 231, an inner strip groove 232 and a threaded cylinder 233, wherein the inner support seat 231 is slidably connected to the inner wall of the left socket 21, the inner strip groove 232 is opened on the surface of the left socket 21 and is connected to the interior of the left socket 21, and the threaded cylinder 233 is slidably connected to the inner wall of the inner strip groove 232 and is fixedly connected to the surface of the inner support seat 231.

[0034] Specifically, the structure and connection relationship of the inner support assembly 23 are further explained. When in use, loosen the fixing screw 243 so that the slide seat 242 can move on the surface of the left frame 11. The movement of the slide seat 242 synchronously drives the fixing screw 243 and the limiting rod 244 to move. The movement of the fixing screw 243 synchronously drives the threaded cylinder 233 and the inner support seat 231 to move. The movement of the inner support seat 231 allows one end of it to enter the interior of the right socket 22, thereby supporting the interior of the right socket 22. The movement of the limiting rod 244 allows one end of it to pass through the through hole 50 and be inserted into the interior of the limiting seat 25. Then, the limiting rod 244 is rotated to screw and fix the limiting rod 244 to the inner wall of the limiting seat 25, thereby connecting the left frame 11 and the right frame 12, and the use effect is good.

[0035] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the limiting assembly 24 includes an outer strip-shaped groove 241, a slide seat 242, a fixed screw 243 and a limiting rod 244, wherein the outer strip-shaped groove 241 is opened on the surface of the left frame 11 and corresponds to the position of the inner strip-shaped groove 232, the slide seat 242 is slidably connected to the inner wall of the outer strip-shaped groove 241, the fixed screw 243 is threadedly connected to the surface of the slide seat 242, and is threadedly connected to the inner wall of the threaded cylinder 233, the limiting rod 244 is threadedly connected to the surface of the slide seat 242, and one end of the limiting rod 244 passes through the through hole 50 into the interior of the limiting seat 25 and is threadedly connected to the inner wall of the limiting seat 25.
