Description

Technical Field

[0001] This utility model relates to the field of chain connecting plate technology, and in particular to a wear-resistant chain connecting plate. Background Technology

[0002] Chains are a versatile mechanical product. Combining the characteristics of gears and belts, they are widely used in transmission, conveying, and other specialized applications. Chain products are categorized according to their basic structure, including the shape of components, the parts meshing with the chain, and the dimensional proportions between components. Among these, the chain connecting plate is a crucial component, used to connect the chain pin and the bushing.

[0003] However, existing chain connectors have certain shortcomings:

[0004] First, the existing chain connecting plates have poor wear resistance. During long-term operation, their edges are easily worn, resulting in uneven stress on the connecting plates and subsequent damage.

[0005] Secondly, existing chain connecting pieces are usually integral metal structures, which are relatively heavy. When the chain is working, the overall weight of the chain will increase, thus affecting the chain's working efficiency.

[0006] Finally, the existing chain connectors have a fixed length. If the chain spacing needs to be adjusted, the connectors of the corresponding length need to be replaced, which is a rather cumbersome operation. Utility Model Content

[0007] The purpose of this application is to provide a wear-resistant chain connector to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this application provides the following technical solution: a wear-resistant chain connecting piece, comprising a chain piece, each chain piece comprising chain segments, two chain segments combined to form a chain piece, the chain segments having the same shape, adjusting components provided on the outer walls of adjacent sides of each chain segment, the adjusting components being adapted to the chain segments, a wear-resistant pad covering the outer wall of the chain piece, the wear-resistant pad being made of wear-resistant rubber material, the wear-resistant pad being bonded to the chain piece, the chain piece being made of high manganese alloy material, and weight-reducing grooves provided on the outer walls of adjacent sides of each chain segment, the weight-reducing grooves being adapted to the chain segments and adjusting components respectively, the weight-reducing grooves having a square structure, and the weight-reducing grooves being located in the middle of the chain segments.

[0009] Preferably, the adjustment component includes adjustment grooves formed on the outer walls of adjacent sides of the chain segment, an adjustment block is slidably installed on the inner wall of the adjustment groove, the adjustment block is slidably connected to the inner wall of the adjustment groove, and the length of the adjustment block is twice the depth of the adjustment groove.

[0010] Preferably, the outer wall of the adjusting block has equally spaced limiting holes, and the top and bottom of the outer wall of the chain segment are threaded with limiting pins, which are adapted to the limiting holes, and the length of the limiting pins is greater than the thickness of the adjusting block.

[0012] Preferably, the chain link has fixing holes at both ends of its outer wall. The fixing holes are arranged in a ring with the center of the mounting hole as the center. The fixing holes penetrate the chain link. A fixing pin is installed on the inner wall of the fixing hole by means of a thread.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, during the operation of the chain links, the wear-resistant pad protects the edges of the chain links to prevent them from wearing out during operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] Example: Reference Figure 1-4 The wear-resistant chain connector shown includes a chain piece 1, which includes chain segments 2. Two chain segments 2 are combined to form a chain piece 1. The chain segments 2 have the same shape. Adjustment components are provided on the outer walls of adjacent sides of the chain segments 2. The adjustment components are adapted to the chain segments 2. The outer wall of the chain piece 1 is covered with a wear-resistant pad 3. The wear-resistant pad 3 is made of wear-resistant rubber and is bonded to the chain piece 1. The chain piece 1 is made of high manganese alloy. Weight reduction grooves 4 are provided on the outer walls of adjacent sides of the chain segments 2. The weight reduction grooves 4 are adapted to the chain segments 2 and the adjustment components, respectively. The weight reduction grooves 4 have a square structure and are located in the middle of the chain segments 2. Mounting holes 5 are provided at both ends of the outer wall of the chain piece 1. The mounting holes 5 penetrate the chain piece 1 and are located at the center of both ends of the outer wall of the chain piece 1.

[0024] Through the above structure: during the operation of chain link 1, the wear-resistant pad 3 protects the edge of chain link 1 to prevent wear during operation. At the same time, chain link 1 is made of high manganese alloy, which has better wear resistance. By combining the wear resistance of chain link 1 itself with the wear resistance of wear-resistant pad 3, the wear resistance of chain link 1 is further improved, making chain link 1 more durable and less prone to wear, which helps to improve its service life. The hollow groove design of weight reduction groove 4 reduces the weight of chain link 1, making chain link 1 lighter. Compared with traditional chain connecting pieces, the wear resistance of chain link 1 is significantly improved, and at the same time, chain link 1 is lighter, which is more in line with the lightweight design of chain.

[0025] like Figure 3As shown, the adjustment assembly includes adjustment grooves 6 formed on the outer walls of adjacent sides of chain segment 2. Adjustment blocks 7 are slidably installed on the inner wall of adjustment grooves 6. Adjustment blocks 7 are slidably connected to the inner wall of adjustment grooves 6. The length of adjustment blocks 7 is twice the depth of adjustment grooves 6. Restriction holes 8 are evenly distributed on the outer wall of adjustment blocks 7. Restriction pins 9 are threadedly installed on the top and bottom of the outer wall of chain segment 2. Restriction pins 9 are adapted to restriction holes 8. The length of restriction pins 9 is greater than the thickness of adjustment blocks 7. Adjustment blocks 7 are slidably connected to the inner wall of adjustment grooves 6. During use, if it is necessary to adjust the chain spacing, it is only necessary to release the restriction pins 9 from the adjustment blocks 7 so that the adjustment blocks 7 can slide along the inner wall of adjustment grooves 6 to adjust the length of chain segments 1, thereby achieving the adjustment of chain spacing.

[0026] like Figure 2 As shown, fixing holes 10 are provided at both ends of the outer wall of the chain link 1. The fixing holes 10 are arranged in a ring with the center of the mounting hole 5 as the center. The fixing holes 10 penetrate the chain link 1. A fixing pin 11 is installed on the inner wall of the fixing hole 10 by means of a thread. The length of the fixing pin 11 is greater than the depth of the fixing hole 10. The fixing holes 10 and the fixing pin 11 facilitate further reinforcement of the inner connecting piece and the outer connecting piece. The chain link 1 will not fall off during long-term operation, the chain is more secure, and the chain can be used for a long time.

[0027] The working principle of this practical application is as follows:

[0028] During the operation of chain link 1, wear-resistant pad 3 protects the edge of chain link 1 to prevent wear during operation. At the same time, chain link 1 is made of high manganese alloy, which has better wear resistance. The wear resistance of chain link 1 itself is combined with the wear resistance of wear-resistant pad 3 to further improve the wear resistance of chain link 1, making chain link 1 more durable and less prone to wear, which helps to improve its service life. The hollow groove design of weight reduction groove 4 reduces the weight of chain link 1, making chain link 1 lighter. Compared with traditional chain connecting pieces, the wear resistance of chain link 1 is significantly improved, and chain link 1 is lighter, which is more in line with the lightweight design of chain.

[0029] During use, if it is necessary to adjust the chain spacing, simply release the restriction pin 9 from the adjustment block 7 and slide the adjustment block 7 along the inner wall of the adjustment groove 6 to adjust the length of the chain piece 1, thereby adjusting the chain spacing. The fixing hole 10 and the fixing pin 11 facilitate further reinforcement of the inner connecting piece and the outer connecting piece. The chain piece 1 will not fall off during long-term work, the chain is more secure, and the chain can be used for a long time.
