Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Embodiment 1

[0023] As Figures 1 - 4 shown, the present invention provides a technical solution: a plastic gearbox convenient for maintenance, including: an auxiliary mechanism 2, the auxiliary mechanism 2 includes a top cover 21, a side plate 22 is provided on one side of the top cover 21, a connecting block 25 is fixedly connected to the bottom side of the side plate 22, an installation mechanism 3 is provided at the bottom of the connecting block 25, the installation mechanism 3 includes a retaining groove body 31, a limiting groove 32 is opened inside the retaining groove body 31, the inner walls of the limiting groove 32 are slidably connected to the outer surfaces of two slide blocks 33, pushing blocks 34 are fixedly connected to one sides of the slide blocks 33 respectively, one ends of spring members 36 are fixedly connected to the other sides of the slide blocks 33 respectively, clamping blocks 35 are fixedly connected to the top sides of the slide blocks 33, the outer surfaces of the clamping blocks 35 are snap - connected to the inner walls of the anti - detachment grooves 26, and the anti - detachment grooves 26 are respectively opened at the bottom side of the connecting block 25, the outsides of the clamping blocks 35 are respectively arranged inside the inlet grooves 37, the inlet grooves 37 are opened at the top of the retaining groove body 31, and the inner walls of the inlet grooves 37 are snap - connected to the outer surface of the connecting block 25.

[0024] In this embodiment, the auxiliary mechanism 2 provided can observe the operation of the internal gear parts and provide the utility of positioning installation. The installation mechanism 3 provided can provide convenient disassembly and assembly operations. The top cover 21 and the side plate 22 are integrally formed. The integrally formed top cover 21 and side plate 22 can provide an operating space for the user during disassembly and assembly. The retaining groove body 31 can enable the slider 33 to slide on its inner wall through the provided limiting groove 32. The slider 33 provides the utility of retaining the pushing block 34. The pushing block 34 can slide in the established slot opened in the retaining groove body 31. And during the process that the pushing block 34 is forced to slide in the established slot opened in the retaining groove body 31, the pushing block 34 will exert pressure on the slider 33. When the slider 33 is under pressure, it will slide in the limiting groove 32 opened in the retaining groove body 31. Since the slider 33 provides the utility of retaining the clamping block 35, and the sliders 33 are connected to each other by the spring member 36. During the process that the slider 33 slides under pressure, it will exert a sub-force on the spring member 36 and cause it to deform. During the deformation of the spring member 36, a relative acting force will be provided. During the process that the slider 33 slides in the limiting groove 32 under pressure, the clamping block 35 connected to it will perform a synchronous displacement. During the displacement process of the clamping block 35, it will perform a displacement operation on the inner side of the inlet groove 37. The inlet groove 37 is opened at the top of the retaining groove body 31. The retaining groove body 31 can enable the connecting block 25 to be inserted therein through the provided inlet groove 37, and the clamping block 35 connected to the slider 33 is engaged with the anti-displacement groove 26 opened in the connecting block 25, thereby realizing the anti-displacement connection.

[0025] Embodiment 2

[0026] As Figures 1 - 4 shown, the inner side of the retaining groove body 31 is fixedly connected to the bottom side of the gearbox body 1. Two positioning slots 12 are opened on one side of the gearbox body 1. The inner walls of the two positioning slots 12 are both engaged with the outer surface of the positioning block 23. The inner sides of the positioning blocks 23 are both fixedly connected to one side of the side plate 22. Connecting grooves are opened on one side of the side plates 22. The inner walls of the connecting grooves are fixedly connected to the outer surface of the observation window 24. The inner sides of the side plates 22 are arranged on one side of the gearbox body 1. The top of the gearbox body 1 is joined and connected to the bottom side of the top cover 21. Shaft holes 11 are opened on both sides of the gearbox body 1. Bearings 13 are arranged outside the shaft holes 11. The inner sides of the bearings 13 are both fixedly connected to one side of the gearbox body 1.

[0027] In this embodiment, the gearbox body 1 provides the function of retaining the retaining groove body 31. When the slider 33 arranged in the retaining groove body 31, its connecting components and the anti - detachment groove 26 opened in the connecting block 25 are in a snap - fit connection state, at this time, the gearbox body 1 and the connecting components of the connecting block 25 will form a relative retaining state. The gearbox body 1 can enable the side plate 22 connected to the positioning block 23 to perform a positioning installation operation during the installation process through the two positioning slots 12 opened. The side plate 22 provides the function of retaining the observation window 24 through the connecting groove opened on one side. By providing the observation window 24, the operation condition of the gear set can be observed. When the positioning slot 12 opened in the gearbox body 1 and the positioning block 23 connected to the side plate 22 are in a snap - fit connection state, the top cover 21 and the side plate 22 will form an integrated connection state with the gearbox body 1. The gearbox body 1 can enable the shaft rod to be placed therein through the shaft hole 11 opened, and the bearing 13 connected to the outside of the shaft hole 11 provides the function of rotating the shaft rod. The gearbox body 1 provides the function of retaining the bearing 13.

[0028] Working principle:

[0029] As Figures 1 - 4 shown, when working inside the gearbox body 1, at this time, the inside can be observed through the observation window 24 connected by the connecting groove opened on the side plate 22. The gearbox body 1 can enable the shaft rod to rotate through the shaft hole 11 and the bearing 13 opened. When it is necessary to repair the gear set, at this time, the push block 34 can be pressed inward. When the push block 34 is under pressure, the slider 33 connected to it will slide in the limit groove 32 opened in the retaining groove body 31. During the sliding process of the slider 33, the clamping block 35 connected to it will gradually disengage from the anti - detachment groove 26 opened in the connecting block 25 connected to the side plate 22. And during the sliding process of the slider 33, the spring member 36 will be gradually deformed and provide a relative acting force. When the connection between the clamping block 35 and the anti - detachment groove 26 opened in the connecting block 25 is disengaged, at this time, the connection between the positioning block 23 connected to the top cover 21 and the side plate 22 and the positioning slot 12 opened in the gearbox body 1 can be disconnected, and the outside of the connecting block 25 can be disengaged from the inlet groove 37 opened in the retaining groove body 31. It should be noted that when installing, the push block 34 needs to be pressed inward.

[0030] The above - mentioned is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above - mentioned embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
