Description

Technical Field

[0001] This utility model relates to the field of chain technology, and in particular to a modular chain structure that can be quickly disassembled and assembled. Background Technology

[0002] Chains, as a common mechanical transmission component, are widely used in various industrial fields, such as bicycles, motorcycles, and automobile engines. In traditional chains, the outer and inner chain plates are usually connected by pins. To ensure the connection is firm, the pin ends are often fixed by an expansion and outward turning process.

[0003] However, when the chain is damaged or needs maintenance, this fixing method makes it difficult to remove the pin from the chain plate because the end of the pin is deformed. Therefore, it takes time to cut and clean the end of the pin, which makes the disassembly of the chain structure difficult and time-consuming.

[0004] Therefore, in order to solve the above problems, this invention proposes a modular chain structure that can be quickly disassembled and assembled. Utility Model Content

[0005] The purpose of this invention is to provide a modular chain structure that can be quickly disassembled and assembled, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular chain structure that can be quickly disassembled and assembled, comprising:

[0007] The outer chain plate, and multiple outer chain plates are symmetrically arranged, with inner chain plates symmetrically arranged at both ends of opposite sides of each outer chain plate;

[0008] A fixing component is used to fix the outer chain plate and the inner chain plate. The fixing component includes an insert part, the end of which is inserted and connected to the connection between the outer chain plate and the inner chain plate. A rolling part for transmission is sleeved on the outside of the insert part. A locking part for fixing the insert part and the outer chain plate is inserted and connected to one end of the insert part.

[0009] Preferably, the insert portion includes a pin, one end of which is inserted and connected to the connection between the outer chain plate and the inner chain plate.

[0010] Preferably, the locking part includes:

[0011] A retaining ring is disposed on the side of the outer chain plate and near one end of the pin.

[0012] A fixing bolt, one end of which is sequentially inserted and connected to the middle of the fixing ring, the side of the outer chain plate, and one end of the pin.

[0013] An anti-loosening component is provided at the intersection of the fixing bolt and the pin, and is used to prevent the fixing bolt from loosening.

[0014] Preferably, the anti-loosening component includes:

[0015] A compression spring is disposed at the intersection of the fixing bolt and the pin;

[0016] A positioning bolt is fitted onto the middle of a compression spring, and the positioning bolt is used to limit the movement of the compression spring.

[0017] Preferably, one end of the pin has a fixed cavity, the compression spring is disposed inside the fixed cavity, and the end of the positioning bolt is fixedly connected to the inner wall of the fixed cavity.

[0018] Preferably, an indicator is provided on the outer side of both the fixing ring and the fixing bolt, and the indicator is used to observe the loosening of the fixing bolt.

[0019] Preferably, the rolling part includes:

[0020] A sleeve, which is fitted onto the outside of the pin and located on the opposite side of the inner chain plate;

[0029] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figure 1-4 As shown:

[0031] Example 1,

[0032] A modular chain structure that can be quickly disassembled and assembled includes: an outer chain plate 1 and a fixing component;

[0033] Specifically, multiple outer link plates 1 are symmetrically arranged, and inner link plates 2 are symmetrically arranged at both ends of opposite sides of the outer link plates 1. The fixing components are used to fix the outer link plates 1 and the inner link plates 2.

[0034] It should be noted that the fixing component includes an insert part, the end of which is inserted and connected to the connection between the outer chain plate 1 and the inner chain plate 2. A rolling part for transmission is sleeved on the outside of the insert part, and a locking part for fixing the insert part and the outer chain plate 1 is inserted and connected to one end of the insert part.

[0035] Specifically, the inserting part includes a pin 3, one end of which is inserted and connected to the connection between the outer chain plate 1 and the inner chain plate 2. The locking part includes a retaining ring 7, a retaining bolt 6, and an anti-loosening component.

[0036] It should be noted that the other end of the pin 3 is expanded and turned outward, while the other end is not turned outward. The fixing ring 7 is set on the side of the outer chain plate 1 and close to one end of the pin 3. One end of the fixing bolt 6 is sequentially inserted and connected to the middle of the fixing ring 7, the side of the outer chain plate 1 and one end of the pin 3. The anti-loosening component is set at the intersection of the fixing bolt 6 and the pin 3. The anti-loosening component is used to prevent the fixing bolt 6 from loosening.

[0037] Specifically, the anti-loosening components include: a compression spring 601 and a positioning bolt 302;

[0038] It should be noted that the compression spring 601 is located at the intersection of the fixing bolt 6 and the pin 3, and the positioning bolt 302 is sleeved on the middle of the compression spring 601. The positioning bolt 302 is used to limit the compression spring 601.

[0039] It should be noted that a fixing cavity 301 is provided at one end of the pin 3, and a compression spring 601 is provided inside the fixing cavity 301. The end of the positioning bolt 302 is fixedly connected to the inner wall of the fixing cavity 301. The inner wall of the fixing cavity 301 is provided with threads for fixing the bolt 6. The compression spring 601, when compressed, generates a thrust on the fixing bolt 6, so that the fixing bolt 6 is in close contact with the threads on the inner wall of the fixing cavity 301, thus preventing the fixing bolt 6 from becoming loose.

[0040] Specifically, indicator marks 8 are provided on the outer side of the fixing ring 7 and the outer side of the fixing bolt 6. After tightening, the two indicator marks 8 are aligned. The loosening of the fixing bolt 6 can be observed by observing the misalignment of the two indicator marks 8.

[0041] Example 2,

[0042] A rolling element is applied to the modular chain structure that can be quickly disassembled and assembled in Embodiment 1;

[0043] The rolling part includes: sleeve 5 and roller 4;

[0044] Specifically, the sleeve 5 is sleeved on the outside of the pin 3 and located on the opposite side of the inner chain plate 2, and the roller 4 is sleeved on the outside of the sleeve 5 and located on the opposite side of the inner chain plate 2. When the roller 4 is sleeved on the sleeve 5, it replaces sliding friction with rolling friction when meshing with the sprocket, which significantly reduces the wear of the sprocket tooth surface.

[0045] In actual use, a fixing component is provided at the connection between the outer chain plate 1 and the inner chain plate 2. The insert part in the fixing component limits the outer chain plate 1 and the inner chain plate 2, and the locking part limits and fixes the insert part to the outer chain plate 1. When disassembling, the fixing bolt 6 is loosened to disengage the fixing ring 7, thereby separating and assembling the pin 3 from the outer chain plate 1 and the inner chain plate 2. Compared with the direct use of the pin end expansion and outward turning process to fix the pin and the chain plate, the locking design of the locking part in this design avoids the time-consuming manual disassembly of the pin end expansion and outward turning, and facilitates quick disassembly and replacement after chain damage.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
