DETAILED DESCRIPTION

[0020] Figures 1 to 5 The utility model provides a schematic structural diagram of an embodiment of a quick-release mechanism for a conveyor belt bottom roller, comprising a spring-type lock 1 and a roller mounting seat 2. The roller mounting seat 2 is an L-shaped structure, which is divided into a vertical section 3 and a horizontal section 4. The horizontal section 4 is clamped on the bottom wall of the conveyor belt lower frame 5, and a hook 6 is provided at the end of the horizontal section 4, and the hook 6 protrudes from the outer wall surface of the conveyor belt lower frame 5. The vertical section 3 is located on the inner side of the conveyor belt lower frame 5, and the vertical section 3 is provided with a mounting portion 8 for mounting a roller 7. The spring-type lock 1 is fixed to the outer wall of the conveyor belt lower frame 5, and the spring-type lock 1 and the hook 6 cooperate with each other to realize the installation or removal of the roller 7.

[0021] The spring-type lock 1 includes a handle 9, a connecting seat 10, and a buckle rod 11. The connecting seat 10 is fixed to the outer side wall of the lower frame 5 of the conveyor belt. The handle 9 is hinged on the connecting seat 10. The buckle rod 11 is movably arranged in the connecting seat 10 through an elastic reset member 12, and the bottom end of the buckle rod 11 is an elliptical ring structure 13 and extends from the bottom of the connecting seat 10. The handle 9 and the buckle rod 11 are located on the same straight line, and the hook 6 is bent downward. The handle 9 is driven to buckle or leave the hook 6 by the elliptical ring structure 13 at the bottom end of the buckle rod 11.

[0022] The connecting seat 10 includes a fixing plate 14 and a mounting frame 15, the mounting frame 15 is fixed on the fixing plate 14, the fixing plate 14 is fixed to the outer side wall of the lower frame 5 of the conveyor belt, and slide grooves are respectively arranged on both sides of the mounting frame 15. The top of the buckle rod 11 extends a slide rod 16 to both sides, and the slide rod 16 is movably arranged in the slide groove, and the elastic reset member 12 is sleeved on the buckle rod 11.

[0023] It also includes a limit block 17 with an L-shaped structure. The limit block 17 is arranged on the bottom wall of the lower frame 5 of the conveyor belt, and a fixed slot 18 is formed between the limit block 17 and the bottom wall of the lower frame 5 of the conveyor belt. The horizontal section 4 is clamped in the fixed slot 18.

[0024] It further includes a stopper 19 which is arranged on the outer side wall of the lower frame of the conveyor belt, and the stopper 19 is located beside the left side of the elliptical ring structure 13 at the bottom end of the fastening rod 11.

[0025] Since the conveyor belt has two working states of forward and reverse rotation, by blocking beside the left side of the bottom end of the fastening rod 11 with the stopper 19, it can prevent the idler mounting seat 2 from moving leftward during reverse rotation, resulting in the horizontal section 4 of the idler mounting seat 2 falling off from the fixed card slot 18.

[0026] The elastic reset member 12 is a spring.

[0027] The installation part 8 is a U-shaped groove.

[0028] During installation, align the installation part 8 on the vertical section 3 of the idler mounting seat 2 with the end shaft of the idler 7, and snap the end shaft of the idler 7 into the installation part 8. At the same time, make the right side of the horizontal section 4 stuck in the fixed card slot 18. Then, bend the handle 9 downward. The handle 9 presses the fastening rod 11 downward, causing the fastening rod 11 to move downward, and making the elliptical ring structure 13 at the bottom end of the fastening rod 11 buckle on the hook 6. At this time, the elastic reset member 12 is compressed. Then, bend the handle 9 upward to make it in a vertical state. At this time, through the acting force of the elastic reset member 12 restoring deformation, the elliptical ring structure 13 tightly buckles on the hook 6, thereby realizing the installation of the idler 7 and increasing the installation stability.

[0029] During disassembly, bend the handle 9 downward. The handle 9 presses the fastening rod 11 downward, causing the fastening rod 11 to move downward, and making the elliptical ring structure 13 disengage from the hook 6, separating the idler mounting seat 2 from the spring-type lock 1, and disassembling the idler mounting seat 2 from the lower frame 5 of the conveyor belt, thereby realizing the disassembly of the idler 7.

[0030] The above detailed description is a specific description of the feasible embodiments of the present invention. This embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification without departing from the present invention shall be included in the patent scope of this case.
