Description

Technical Field

[0001] This utility model relates to mechanical parts, and more particularly to bicycle sprockets and their components, specifically a plastic chain cover fixing structure. Background Technology

[0002] Currently, the following problems exist when fixing plastic chain covers:

[0003] Fasteners are required for fixing: Traditional fixing methods usually require the use of fasteners such as screws and nuts, which increases material costs and assembly time;

[0004] Assembly is relatively complicated: using fasteners for fixing requires multiple steps, such as aligning the holes and tightening the screws, which makes the assembly process complicated and time-consuming;

[0005] High cost: The high labor costs in the procurement and assembly of fasteners lead to an increase in overall costs;

[0006] Complex assembly structure: In some cases, specialized locking tools or pressing pressure equipment may be required, which further increases the complexity of the equipment and operation;

[0007] Therefore, it is necessary to provide a plastic chain cover fixing structure to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a plastic chain cover fixing structure.

[0009] The technical solution is as follows:

[0010] A plastic chain cover fixing structure includes a sprocket, a sprocket body, an outer ring, and a plurality of evenly arranged plastic chain cover fixing grooves. A plastic chain cover is fixedly mounted on the sprocket. The plastic chain cover includes a cover body and a plurality of fixing buckles corresponding to the plastic chain cover fixing grooves. The fixing buckles are fastened to the evenly arranged plastic chain cover fixing grooves to form a quick-fixing structure for the plastic chain cover.

[0011] Furthermore, the sprocket body has a sprocket center section, which is fixedly connected to the outer ring of the sprocket by several connecting support plates, and the plastic chain cover fixing groove is located between adjacent connecting support plates.

[0012] Furthermore, the number of plastic chain cover fixing slots is 4-6.

[0013] Furthermore, the fixing buckle includes an elastically deformable part body, which has a fastening boss.

[0014] Furthermore, the fastening boss has an outward expansion that facilitates the deformation of the main body of the elastic deformation section and pushes it into the slope.

[0015] Furthermore, the slope of the outward-expanding incline is 45-60°.

[0016] Furthermore, a positioning platform for the fixing buckle fastening part is provided in the fixing groove of the plastic chain cover.

[0017] Compared with existing technologies, this invention enables rapid fixing of plastic chain caps without the need for traditional fasteners, resulting in high assembly efficiency, excellent assembly quality, and easier control of production costs. Attached Figure Description

[0021] Example:

[0022] Please see Figure 1-3 This embodiment demonstrates a plastic chain cover fixing structure, including a sprocket, a sprocket body 1, a sprocket body 1 having a sprocket outer ring 2, a plurality of evenly arranged plastic chain cover fixing grooves 3 on the sprocket outer ring 2, a plastic chain cover 4 fixedly mounted on the sprocket, the plastic chain cover 4 including a chain cover body 41 corresponding to the plastic chain cover fixing grooves, a plurality of fixing buckles 5 evenly arranged on the chain cover body, the plurality of fixing buckles 5 corresponding to the plurality of evenly arranged plastic chain cover fixing grooves 3 to fasten, forming a quick fixing structure for the plastic chain cover.

[0023] The sprocket body 1 has a sprocket center part 11, and the sprocket center part 11 is fixedly connected to the sprocket outer ring 2 by a number of connecting support plates 12. The plastic chain cover fixing groove 3 is located between adjacent connecting support plates 12.

[0024] The number of plastic chain cover fixing slots 3 is 4-6.

[0025] The fixing buckle 5 includes an elastically deformable part body 51, and the elastically deformable part body 51 has a fastening boss 52.

[0026] The fastening boss 52 has an outward-expanding ramp 53 that facilitates the deformation of the main body of the elastic deformation part.

[0027] The slope of the outward-expanding push-in ramp 53 is 45-60°.

[0028] The plastic chain cover fixing groove 3 is provided with a fixing buckle fastening part positioning platform 6.

[0029] Compared with existing technologies, this invention enables rapid fixing of plastic chain caps without the need for traditional fasteners, resulting in high assembly efficiency, excellent assembly quality, and easier control of production costs.
