Description

Technical Field

[0001] This utility model relates to the field of cable chain technology, specifically to a closed-structure, easy-to-open, quiet cable chain. Background Technology

[0002] Cable chains are suitable for reciprocating motion applications and are widely used in automated equipment such as CNC machine tools, robotic arms, lifting and transportation equipment, and automated warehouses. They can provide traction and protection for built-in cables, oil pipes, air pipes, water pipes, etc.

[0003] A cable chain is formed by connecting several links. Each link includes two parallel chain plates and two sealing plates located between the two chain plates to connect them. The two sealing plates are arranged vertically and horizontally. Currently, disassembling the sealing plates is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the existing technology, which is relatively cumbersome, time-consuming and labor-intensive to disassemble the closed plate, so as to provide a closed structure that is quick and easy to disassemble and open, and a silent cable chain.

[0005] Therefore, this utility model provides a closed-structure, easy-to-open, silent cable chain, formed by splicing multiple chain links. Each chain link includes a first chain plate and a second chain plate arranged left and right, and an outer sealing plate and an inner sealing plate arranged vertically to connect the first chain plate and the second chain plate respectively. One end of the outer sealing plate is rotatably connected to the second chain plate, and the other end is connected to the first chain plate through a first buckle structure. The first buckle structure includes: a first locking block, disposed on the inner wall of the first chain plate and extending toward the second chain plate arranged opposite to it; the first locking block has a first groove near the first chain plate for inserting an external screwdriver, and a slot disposed in the middle; the side wall of the first groove is provided with a first inclined surface; and a first slot, disposed at one end of the outer sealing plate, which can be adapted to engage with the first locking block; the first slot has a first abutment block located at its end that can extend into the first groove, and an insertion block disposed in the middle that is adapted to engage with the slot.

[0006] The top of the second chain plate has a first connecting block and rotating shaft grooves disposed on both sides of the first connecting block. The inner wall of the first connecting block is provided with an arc-shaped groove. The other end of the outer sealing plate has a second groove corresponding to the first connecting block and two rotating shafts disposed on both sides of the second groove. The two rotating shafts are rotatably installed in the corresponding rotating shaft grooves. The bottom of the second groove is provided with a limiting block that is movably installed in the arc-shaped groove.

[0007] Both ends of the inner sealing piece are connected to the corresponding first chain plate or second chain plate through a second snap-fit ​​structure. The second snap-fit ​​structure includes: a second snap block, which is disposed on the inner wall of the first chain plate or the second chain plate and extends toward the chain plate to which it is disposed; and a second snap groove, which is disposed at both ends of the inner sealing piece and can be adapted to snap-fit ​​with the second snap block.

[0008] The bottom of the second card block is provided with a protrusion, and the two sides of the protrusion are provided with second inclined surfaces. The middle of the second card slot is provided with a through hole for the protrusion to be inserted. When the second card block is engaged with the second card slot, there is a gap between the second inclined surfaces on both sides of the protrusion and the inner wall of the through hole for the insertion of an external screwdriver.

[0009] Each of the chain links has an outer closure piece having a first closure portion on one side thereof, the first closure portion extending into the interior of an adjacent chain link, and each of the chain links has an inner closure piece having a second closure portion on one side thereof, the second closure portion extending into the interior of an adjacent chain link, the first closure portion and the second closure portion being located on both sides of the chain link in the width direction.
