[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 5As shown, this application provides a combined gear, including: a combined gear 100, including a gear body 10, a gear ring 20, and a connecting hole 50, the outer side of the gear ring 20 is provided with teeth 30, and the connecting hole 50 is provided with a positioning hole 60; an assembly component 40, disposed at the connection between the gear body 10 and the gear ring 20, including a plurality of sets of locking blocks 41 fixed to the inner side of the gear ring 20, each set of locking blocks 41 having a positioning groove 42 on its outer side, the outer side of the gear body 10 having a locking groove 43, and the inner side of the locking groove 43 having a moving groove 44, the inner side of the gear body 10 having a rotating groove 45, and the inner side of the rotating groove 45 being provided with a rotating ring 46, the outer side of the rotating ring 46 being provided with a support column 47, and one side of the support column 47 being provided with a positioning block 48.

[0028] After adopting the above technical solution, since the assembly component 40 is set at the connection between the gear body 10 and the gear ring 20, when disassembling the gear ring 20, the user only needs to use the assembly component 40 to release the gear body 10 from the gear ring 20 and quickly disassemble the gear ring 20. This can solve the problem that when a single tooth is damaged, the entire gear assembly usually needs to be replaced, which has certain shortcomings: First, the gear body and the tooth are an integrated structure, resulting in insufficient material utilization; second, replacement requires disassembling the entire transmission system, with an average downtime of 4-8 hours, leading to maintenance difficulties; and finally, most of the undamaged gear parts are forced to be scrapped, causing a waste of resources.

[0029] It should be noted that when a group or several groups of teeth 30 are damaged, and the user disassembles the tooth ring 20, by applying force clockwise to the hand-held disassembly block 411, the hand-held disassembly block 411 moves along the inside of the auxiliary groove 412, which in turn drives a group of support columns 47 to move along the inside of the moving groove 44. During the movement of the support columns 47, the positioning blocks 48 are disengaged along the inside of the positioning groove 42, and the rotating ring 46 is rotated along the inside of the rotating groove 45. When the rotating ring 46 rotates, all the support columns 47 and positioning blocks 48 move along the inside of the moving groove 44 and the positioning groove 42. At the same time, all the support springs 410 are squeezed along the inside of the moving groove 44 until one side of the hand-held disassembly block 411 contacts the other side of the auxiliary groove 412. At this time, all the positioning blocks 48 are disengaged from the inside of the positioning groove 42, and the tooth ring 20 is pulled along one side of the gear body 10, thereby driving several groups of locking blocks 41 to disengage from the inside of the locking groove 43, thus quickly disassembling the tooth ring 20.

[0030] Similarly, when the toothed ring 20 needs to be installed, simply align all the locking blocks 41 with the locking slots 43, and forcefully press the toothed ring 20 so that all the locking blocks 41 contact all the rounded corners 49, pressing all the positioning blocks 48 so that the positioning blocks 48 are squeezed into the interior of the moving groove 44, thereby locking the locking blocks 41 into the bottom of the locking slot 43. At this time, the positioning groove 42 corresponds to the positioning block 48. Under the elastic potential energy of the support spring 410, the support column 47 and the positioning block 48 are driven to reset, locking the positioning block 48 into the interior of the positioning groove 42, thereby positioning the locking block 41 inside the locking slot 43. Similarly, the remaining locking blocks 41 are positioned simultaneously through the above steps. The structure is simple and the operation is convenient.

[0031] In one optional embodiment, the teeth 30 and the toothed ring 20 are an integral structure, and the number of teeth 30 is several groups and distributed in an array, so as to ensure that the toothed ring 20 can be replaced when the teeth 30 are damaged.

[0032] In an optional embodiment, the connecting hole 50 penetrates the middle of the gear body 10, and the positioning hole 60 is connected to the connecting hole 50. The positioning hole 60 has a rectangular structure and can be used to install the gear body 10. The corresponding drive shaft can be inserted into the interior of the connecting hole 50, and a buckle can be inserted into the positioning hole 60 to install the gear body 10.

[0033] In an optional embodiment, the positioning groove 42 is a rectangular structure, which facilitates the insertion and positioning of the positioning block 48, and the thickness of the positioning groove 42 is less than the thickness of the card block 41, ensuring the overall strength of the card block 41.

[0034] In an optional embodiment, the inner edge of the slot 43 has an arc-shaped structure. The number of slots 43 is equal to the number of blocks 41, and the two are compatible to facilitate the connection between the slots 43 and blocks 41, ensuring that the gear ring 20 does not wobble along the outer side of the gear body 10, thus providing stability for the subsequent use of the gear. The number of moving slots 44 is equal to the number of slots 43, and the two are connected. The moving slots 44 correspond to the positioning slots 42, and the moving slots 44 are connected to the rotating slots 45, facilitating the subsequent movement of the rotating ring 46 and the support column 47.

[0035] In one optional embodiment, the rotating ring 46 and the support column 47 are an integral structure, and the number of support columns 47 is several groups arranged in an array. The support columns 47 are adapted to the moving groove 44, and the rotating ring 46 is adapted to the rotating groove 45. During the movement of the support column 47, the rotating ring 46 can be driven to rotate, and then the rotating ring 46 can drive the other support columns 47 to rotate, ensuring the linkage of the support columns 47.

[0036] In an optional embodiment, the positioning block 48 and the support column 47 are an integral structure. The positioning block 48 has a rounded corner 49 on one side edge, which can be inserted into the positioning groove 42 to position the card block 41 inside the groove 43.

[0037] In an optional embodiment, a support spring 410 is installed on one side of the support column 47, and the number of support springs 410 is equal to the number of moving slots 44. It can store force during the compression process of the support column 47 and the positioning block 48, and pop the support column 47 and the positioning block 48 back to their original positions when the positioning slot 42 is aligned with the positioning block 48.

[0038] In one optional embodiment, a hand-held disassembly block 411 is fixedly connected to the outer side of one set of support columns 47. An auxiliary groove 412 adapted to the hand-held disassembly block 411 is opened on the outer side of the gear body 10. The auxiliary groove 412 is connected to the moving groove 44, which can easily drive the support columns 47 to rotate. This allows all the support columns 47 to drive the positioning block 48 out of the positioning groove 42, release the locking block 41 from the positioning in the locking groove 43, and quickly disassemble the gear ring 20.
