Description

Technical Field

[0001] This utility model relates to the field of cable chain technology, specifically to a small-pitch, highly protective enclosed cable chain. Background Technology

[0002] Cable chains are widely used in automated equipment to protect and guide built-in cables, oil pipes, etc.

[0003] Existing enclosed cable chains typically divide the internal space into different channels by incorporating separators within the chain links to achieve orderly cable separation. However, in actual operation, especially during long-stroke, high-frequency reciprocating motion, the cable chain constantly bends and stretches. Undue contact and interference can easily occur between the separators and the enclosed sections located inside the cable chain. This continuous hard friction and scraping not only generates noise and wear debris but also causes premature wear, deformation, or even damage to the separators or enclosed sections, severely impacting the overall stability and lifespan of the cable chain and increasing equipment maintenance costs. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defect of easy interference between the separator and the closed plate located inside the cable chain in the prior art, thereby providing a small-pitch, highly protective closed cable chain with a long service life.

[0005] Therefore, this utility model provides a small-pitch, high-protection enclosed cable chain, which is formed by splicing multiple chain links. Each chain link includes an outer enclosing plate and an inner enclosing plate, as well as a separator plate installed between the outer enclosing plate and the inner enclosing plate. The inner enclosing plate has a closing body, and a first closing part and a second closing part respectively disposed on both sides of the closing body. The first closing part extends into the interior of the chain link, and the separator plate has a first clearance groove for avoiding the end of the first closing part.

[0006] The contact surface between the first enclosure and the cable is arc-shaped.

[0007] During operation, the multiple arc-shaped contact surfaces of the multiple first closed portions of the curved section of the cable chain belong to different parts of the same circumference.

[0008] A first groove is provided between the first sealing part and the sealing body, and the first groove faces the inside of the chain link.

[0009] Both the outer and inner sealing plates have locking blocks on their inner sides, and the upper and lower sides of the separator are formed with locking grooves that are adapted to and connected to the corresponding locking blocks.

[0010] The first clearance groove is formed on both the upper and lower sides of the separator.

[0011] The main body of the separator is elliptical.

[0012] The cable chain is fitted with connectors at both ends, the connectors having screw mounting holes arranged vertically and an arc-shaped second clearance groove for avoiding the screws.

[0013] The technical solution of this utility model has the following advantages: 1. The small-pitch, high-protection enclosed cable chain provided by this utility model has a first clearance groove on the separator plate to avoid the end of the first enclosure, thereby avoiding direct interference and wear between the separator plate and the inner enclosure plate when the cable chain is bent, and extending the overall service life of the cable chain.

[0014] 2. The small-pitch, high-protection enclosed cable chain provided by this utility model has an arc-shaped contact surface between the first enclosed part and the cable. The arc-shaped contact surface is more compatible with the shape of the circular cable, and the guidance is smoother. Furthermore, the first enclosed parts of the inner enclosed plates of multiple chain links can jointly form a smooth and continuous guide surface, so that the cable will not be rubbed when the cable chain has a smaller bending radius, further reducing the stress and wear on the cable.

[0015] 3. The small-pitch, high-protection enclosed cable chain provided by this utility model has a first groove facing the inside of the chain link between the first enclosing part and the enclosing body, thereby reducing the contact area between the enclosing plate and the cable and reducing wear.

[0016] 4. The small-pitch, high-protection enclosed cable chain provided by this utility model has joints installed at both ends of the cable chain. The joints have screw mounting holes set at the top and bottom, as well as arc-shaped second clearance grooves for avoiding screws, thereby providing operating space when installing screws.
