[0025] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that a more thorough understanding of the invention will be achieved and that the full scope of the invention will be conveyed to those skilled in the art.

[0026] like Figure 1 , 2 As shown, this embodiment of a conveniently assembled and disassembled roller conveyor includes a roller 1 and two side plates 2, with the roller 1 installed between the two side plates 2. Multiple rollers 1 are interconnected via multi-wedge belts 6. The two side plates 2 are fixedly connected by two transverse supports 7 located at the bottom. A multi-wedge belt guard plate 3 is installed above the multi-wedge belt 6, mounted on one side plate 2. Guardrail brackets 4 are installed on both side plates 2, and guardrails 5 are installed on the guardrail brackets 4. Driven by an electric roller, all rollers 1 rotate simultaneously to achieve the conveying action of goods.

[0027] The roller 1 and the side plate 2 are installed using a snap ring locking mechanism.

[0028] Cooperate Figure 3 As shown, bosses 11 are provided on both sides of the roller 1. Next to the bosses 11 are multi-wedge pulleys 12 and roller surfaces 13. The bosses 11 are preferably quasi-cylindrical bosses, having two parallel side surfaces. Figure 4 As shown, the upper end of the side plate 2 is bent outward, and slots 21 are evenly distributed at the bend. The slots 21 preferably adopt a structure that is wider at the top and narrower at the bottom.

[0029] Cooperate Figure 5As shown, the clamping spring 8 is in a H-like structure, the upper part of the H-like structure is two elastic ears 81, the upper end of each elastic ear 81 is bent to one side, the bent end is in a right triangle shape, and a round hole 82 is arranged on the bent end of each elastic ear 81, the round hole 82 is used to accommodate the tip of the pliers. The middle part of each elastic ear 81 extends outwardly with a clamping jaw 83, and the lower end of the H-like structure of the clamping spring 8 is bent to one side, and the bending direction is the same as that of the elastic ear 81. The clamping spring 8 can realize six degrees of freedom constraint through the bent end of the elastic ear 81, the clamping jaw 83 and the lower part of the H-like structure.

[0030] Cooperation Figure 6 、 7 As shown, when installed, the protrusions 11 on both sides of the roller 1 are just placed in the clamping grooves 21 of the side plates 2 and extend from one side of the side plates 2, and the protrusions 11 can be locked in the clamping grooves 21 by the clamping spring 8. Specifically, when installed, the round holes 82 on the two elastic ears 81 are clamped (clamped inward) by the pliers, and are placed in the clamping grooves 21 of the side plates 2 from top to bottom, so that the lower part of the H-like structure clamps the extending end of the protrusions 11, and the mutually parallel side surfaces of the protrusions 11 are respectively attached to the lower part of the H-like structure; at this time, the two clamping jaws 83 are clamped on the side surface of the side plate 2 close to the roller 1; after the pliers are released, the two elastic ears 81 of the clamping spring 8 are loosened, the bent end of the elastic ear 81 passes through the clamping groove 21, so that the upper surface of the bent end of the elastic ear 81 is in contact with the lower surface of the bent end of the side plate 2 and is clamped, at this time, the six degrees of freedom of the clamping spring 8 are constrained, so that the clamping spring 8 will not fall off in the natural state, thereby fixing the roller 1. After the clamping spring 8 is locked, the round holes 82 are exposed from the upper part of the clamping grooves 21. When the roller 1 is disassembled, the clamping spring 8 can be easily taken out by clamping the round holes 82 with the pliers and pulling the clamping spring 8 upward.
