Description

Technical Field

[0001] This utility model relates to the field of chain link connection technology, specifically a flat chain link for compact chains. Background Technology

[0002] As a chain connecting device, the connecting link has the characteristics of fast and stable connection. Flat connecting links are mostly made of two half-links spliced ​​together. Flat connecting links must be used in complete cooperation with the chain. Flat connecting links can pass through sprockets just like the chain, so their outer contours are almost exactly the same as the chain.

[0003] To reduce the opening volume and enhance the strength of a flat connecting link, a flat connecting link (see patent number: 201921459992.9) is provided, comprising a first half-link, a second half-link, and a limiting block. The first half-link is provided with a first engaging block and a first engaging groove, and the second half-link is provided with a second engaging block and a second engaging groove. The first engaging groove is provided with a first air hole, and the second engaging groove is provided with a second air hole. The first engaging block is provided with a first pin hole, and the second engaging block... The upper part is provided with a second pin hole, and the limiting block is provided with a third pin hole; the first pin hole, the second pin hole, the third pin hole, the first air hole and the second air hole are coaxial, the first pin hole, the second pin hole, the first air hole and the second air hole have the same diameter and are connected by a pin shaft; the first air hole and the second air hole can be used as both air holes and pin holes, avoiding the need to drill holes again on the first half link and the second half link; the axis of the first pin hole is perpendicular to the force direction of the flat connecting link, which improves the strength of the first half link and the second half link.

[0004] However, some compact chain-type flat connecting links currently used on the market are inconvenient to disassemble. Disassembling the connecting link usually requires hammering the cylindrical pin out of the connecting link, which is time-consuming and laborious. Frequent hammering can also deform the cylindrical pin, affecting subsequent use and increasing maintenance costs. Utility Model Content

In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0022] like Figures 1 to 3 As shown, this utility model provides a flat connecting link for compact chains, including a connecting link 1, a locking assembly 2 inside the connecting link 1, and a locking ring 3 on one side of the connecting link 1.

[0023] The snap-fit ​​assembly 2 includes two sets of limiting blocks 201. Both sides of the two sets of limiting blocks 201 are provided with elastic elements 202. A rotating frame 203 is provided between the two sets of limiting blocks 201. A knob 208 is provided at one end of the rotating frame 203. Grooves 206 are provided on both sides of the rotating frame 203. A connecting rod 205 is provided at one end of the two sets of grooves 206. A locking post 207 is provided on the side of the two sets of connecting rods 205 near the rotating frame 203. A locking block 204 is provided at the end of the two sets of limiting blocks 201 away from the rotating frame 203.

[0024] like Figures 1 to 3 As shown, both the connecting ring 1 and the retaining ring 3 are made of high manganese steel.

[0025] In this embodiment, the wear resistance and corrosion resistance of high manganese steel ensure the service life of the device, while its impact resistance, toughness, and plasticity ensure that the device is not easily deformed and facilitate the manufacture of the device.

[0026] like Figures 1 to 3 As shown, the locking block 204 is connected to the limiting block 201 by locking teeth.

[0027] In this embodiment, the locking block 204 and the limiting block 201 provide a secure and tight engagement between the retaining ring 3 and the connecting ring 1, preventing separation during use.

[0028] like Figures 1 to 3 As shown, both sets of limiting blocks 201 are elastically connected to the internal connection ring 1 through elastic elements 202.

[0029] In this embodiment, the elastic element 202 is also called a spring. A spring is a mechanical part that works by utilizing elasticity. A part made of elastic material deforms under the action of external force and returns to its original shape after the external force is removed. It is also called a "spring". It is generally made of spring steel. There are many types of springs. According to their shape, they mainly include helical springs, spiral springs, leaf springs, and special-shaped springs. This embodiment mainly uses helical springs to achieve self-locking operation.

[0030] like Figures 1 to 3 As shown, both sets of limiting blocks 201 are internally movablely connected to the connecting chain ring 1 via connecting rod 205, rotating frame 203, groove 206 and locking post 207.

[0031] In this embodiment, the above structure allows the two sets of limiting blocks 201 to move inward by rotating the rotating frame 203, causing the limiting blocks 201 to disengage from the locking block 204, thereby separating the locking ring 3 and the connecting ring 1.

[0032] like Figures 1 to 3 As shown, the retaining ring 3 is detachably connected to the connecting ring 1 via the retaining block 204 and the limiting block 201.

[0033] In this embodiment, multiple sets of devices can be connected quickly and easily, and the connection is secure, thereby increasing the worker's work efficiency.

[0034] The working principle of this utility model is as follows: When multiple sets of devices need to be connected, a set of retaining rings 3 are inserted into another set of connecting rings 1, and then the retaining rings 3 are inserted into the corresponding connecting rings 1. While pushing inward, the retaining block 204 presses the limiting block 201 inward to compress the elastic element 202, thereby performing the retaining ring 3 and connecting ring 1 to engage and fix them. This operation is repeated to connect multiple sets of connecting rings 1.

[0035] When it is necessary to separate the retaining ring 3 from the connecting ring 1, rotate the knob 208. The knob 208 drives the rotating frame 203 to rotate, causing the grooves 206 on both sides to rotate as well. The retaining pins inside the grooves 206 move inward, which in turn drives the connecting rod 205 to move inward. The two sets of limiting blocks 201 also move inward, causing the retaining block 204 to disengage from the limiting block 201. Then the retaining ring 3 can be removed to perform the separation work.

[0036] The snap-fit ​​component 2 in this device can quickly connect multiple devices, and the operation is convenient and the connection is firm, thereby increasing the worker's work efficiency.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
