[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following combines the drawings and examples, and further specifically describes the chain belt easy dismounting and connecting structure of the utility model. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more than two;The orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and is not intended to indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the utility model, it is necessary to point out that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected;It can be mechanically connected, or it can be electrically connected;It can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements.For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0023] As Figure 1 , Figure 2 , Figure 3 shown, a chain belt easy disassembly and connection structure, comprising a plurality of chain belt blocks 100, constituting a ring or arc shape, the chain belt block 100 includes a one end of the bolt part 110 and chain belt block main body 120, the bolt part 110 and chain belt block main body 120 are integrally formed, the chain belt block main body 120 is away from the bolt part 110 one end of the recess type C type groove 122;The whole chain belt easy disassembly and connection structure is connected by a plurality of groups of two adjacent bolt part 110 and another adjacent C type groove 122 mortise joint.
