Description

Technical Field

[0001] This utility model relates to the field of cable chains, specifically a buffer-type silent cable chain that is easy to assemble and disassemble. Background Technology

[0002] Currently, cable chains are widely used in many fields such as CNC machine tools, stone machinery, glass machinery, door and window machinery, injection molding machines, robotic arms, lifting and transportation equipment, and automated warehouses. Cable chains can provide traction and protection for the internal cables, oil pipes, air pipes, water pipes, etc. of machinery, while making the overall machinery look more aesthetically pleasing.

[0003] A typical cable chain consists of several links. In existing technology, each link is assembled in a "U" shape using two side plates and two crossbars. The crossbars are fixed to the left and right side plates of the link, but the overlapping area has a latch and insufficient space to insert tools for disassembly, resulting in excessive time wasted during disassembly and reassembly. Several links can be connected by elastic bodies with round shafts at both ends. When the cable chain rotates relative to each other, the elastic body undergoes elastic deformation. A limiting block of one link inserts into a limiting groove of another link. The limiting groove limits the rotation trajectory of the limiting block, i.e., the movement trajectory of the cable chain. When the cable chain reciprocates at high speed, the limiting block impacts the inner walls of the limiting grooves, generating noise. Utility Model Content

[0004] To achieve the above objectives, the purpose of this utility model is to provide a buffer-type silent cable chain that is easy to assemble and disassemble, which can solve the shortcomings of existing cable chains such as general noise reduction effect and high assembly time and cost, thereby providing a silent cable chain with good noise reduction effect and convenient assembly and disassembly. This utility model provides the following technical solution:

[0005] A soft-close, silent cable chain that is easy to assemble and disassemble includes multiple links connected end-to-end. Each link includes a left side plate, a right side plate, an elastomer, and a crossbar. The left and right side plates form a main body and are mirror images of each other. The elastomer and crossbar are detachably mounted on the main body. Two branch plates made of elastic material extend from the middle of the elastomer, and the two branch plates are located above and below the central circular holes on the inner cavities of adjacent main body connections, respectively. The main body is provided with limit blocks and limit grooves that fit the limit blocks. The links move... During reciprocating motion, the limiting block of the chain link will make a certain angle of circular motion in the limiting groove of the adjacent chain link. When it moves to the maximum and minimum angles, the limiting block will collide with the edge of the limiting groove and stop rotating. At the same time, when two adjacent chain links rotate relative to each other, the main body will rotate and first contact the branch plate, causing the branch plate to undergo elastic deformation. The two then rotate together to another adjacent chain link, thereby colliding and squeezing, reducing the rotation speed of the main body. The movement process occurs before the limiting block collides with the edge of the limiting groove, thereby achieving the purpose of buffering and reducing the noise during the operation of the cable chain.

[0006] As a further embodiment of this utility model: both ends of the elastic body are provided with round shafts, and both sides of the left side plate and the right side plate of the chain link are provided with shaft holes, and the chain links are connected by the cooperation of the round shafts and shaft holes.

[0007] As a further embodiment of this utility model, disassembly holes are provided at the connection points of the crossbar and the left side plate of the chain link, and at the connection points of the crossbar and the right side plate of the chain link, for easy insertion of disassembly tools. The disassembly tools and disassembly holes utilize the lever principle, requiring only slight force to disassemble the crossbar from the left side plate or the right side plate of the chain link, reducing structural damage to the fastening points caused by forceful disassembly and reducing the user's wiring time cost.

[0008] As a further embodiment of this utility model, the limiting groove and the limiting block are both located on the left side plate of the chain link or both on the right side plate of the chain link, which facilitates the cooperation of the same side plates of two adjacent chain links.

[0009] As a further embodiment of this invention, the elastomer is made of one of polypropylene, thermoplastic polyurethane elastomer rubber, thermoplastic elastomer or EPDM rubber.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This product reduces the instantaneous speed of chain link impact by adding buffered branch plates between the main body of the chain links, thereby reducing the noise of the cable chain operation; by modifying the structure of the crossbar, disassembly tools can be easily inserted, and the buckle structure can be easily pried open using the lever principle, reducing the time cost of cable chain assembly.

[0021] Example 1, please refer to Figure 1 and Figure 4This utility model provides a shock-absorbing silent cable chain that is easy to assemble and disassemble. It includes multiple chain links connected end-to-end. Each chain link includes a left side plate 1, a right side plate 2, an elastic body 3, and a crossbar 4. The left side plate 1 and the right side plate 2 form a main body and are mirror images of each other. The elastic body 3 and the crossbar 4 are detachably mounted on the main body. Two branch plates 5 made of elastic material extend from the middle of the elastic body 3. The two branch plates 5 are located above and below the central circular hole on the inner cavity surface of the connection between two adjacent main bodies, respectively. The branch plates 5 provide a buffering effect, reducing the instantaneous speed of the chain link during impact, thereby reducing noise. The chain link is equipped with a limiting block 7 and a limiting groove 8 that matches the limiting block 7. When the chain link reciprocates, the limiting block 7 of the chain link will make a certain angle of circular motion in the limiting groove 8 of the adjacent chain link. When the chain link moves to the maximum angle and the minimum angle, the limiting block 7 will collide with the edge of the limiting groove 8 and stop rotating. At the same time, when two adjacent chain links rotate relative to each other, the main body will rotate and first contact the branch plate 5, causing the branch plate 5 to undergo elastic deformation. The two then rotate together to the adjacent chain link, thereby colliding and squeezing, reducing the rotation speed of the main body. The movement process occurs before the limiting block 7 collides with the edge of the limiting groove 8, thereby achieving the purpose of buffering and reducing the noise during the operation of the cable chain.

[0022] In one embodiment of this utility model, both ends of the elastic body 3 are provided with round shafts, and both sides of the left side plate 1 and the right side plate 2 of the chain link are provided with shaft holes.

The disassembly tool and the disassembly hole 6 utilize the lever principle, and only a slight force is needed to disengage the crossbar 4 from the left side plate 1 or the right side plate 2 of the chain link, reducing structural damage to the fastening joint caused by forceful disassembly and reducing the user's wiring time cost.

[0024] In one embodiment of this utility model, the limiting groove 8 and the limiting block 7 are both located on the left side plate 1 of the chain link or both located on the right side plate 2 of the chain link, so as to facilitate the cooperation of the same side plates of two adjacent chain links.

[0025] In one embodiment of this utility model, the elastomer 3 is made of one of polypropylene, thermoplastic polyurethane elastomer rubber, thermoplastic elastomer or EPDM rubber. The material is readily available, easy to process, and has good performance.
