Description

[Technical Field]

[0001] This invention relates to cable protection chains, and in particular to a detachable cable protection chain structure. [Previous Technology]

[0002] Cable protection chains are mainly used for the protection of cables or pipelines in automated machinery. They ensure that cables or pipelines can move smoothly when the machinery is in motion, preventing them from getting tangled or knotted due to the movement, thereby avoiding damage and breakage.

[0003] Referring to Figure 1, the cable protection chain 10 currently on the market is usually composed of a series of interconnected links 11. The first link 12 and the last link 13 are fixed to the base or slide (not shown in the figure) to form a channel 14 for protecting cables or pipelines. However, when it is necessary to replace or repair the cables or pipelines in the cable protection chain 10, since the first link 12 is integrally formed into a ring and has a plurality of locking parts 121 that are locked on the slide, the first link 12 must be completely removed from the slide in order to remove the cable or pipeline from the first link 12 for repair, highlighting the inconvenience of repair. [Summary of the Invention]

Implementation Method

[0014] Referring to Figures 2 to 4, the detachable cable protection chain structure provided in the first embodiment of the present invention mainly consists of a chain link seat 20 and a chain link cover 30, wherein:

[0015] The link seat 20 has a longitudinal cross-section that is generally U-shaped, and has a bottom 21, two seat sides 22 extending upward from both sides of the bottom 21, and two first connecting structures 23 respectively provided on the two seat sides 22; in this embodiment, each of the first connecting structures 23 includes a connecting groove 231 recessed downward from the top surface of the seat side 22, and a positioning hole 2 transversely provided on the side of the seat side 22 and communicating with the connecting groove 231. 32, but not limited thereto, the connecting groove 231 and the positioning hole 232 may also be in the form of protrusions; in addition, the link seat 20 also has a first locking part 24 connecting the bottom 21 of the seat and an outer pivot part 25 extending rearward from each side 22 of the seat; the first locking part 24 has two first locking holes 241 for locking onto the slide 91 (as shown in Figure 6), and the outer pivot part 25 is used to pivotally connect other links 96; referring to Figures 6 and 7, the bottom 21 of the link seat 20 is provided with a horizontal U-shaped mounting groove 211, which does not penetrate the first locking part 24. A cable guide plate 40 is installed in the mounting groove 21; the cable guide plate 40 provides guidance for the neat arrangement of the machine's cables, making it easy to see the wire markings.

[0016] The link cover 30 is detachably assembled on the link seat 20 and has one side covering the top 31 of the bottom 21 of the seat, two cover side portions 32 respectively provided on both sides of the top 31 of the cover, two second connecting structures 33 respectively provided on the two cover side portions 32 and detachably connected to the first connecting structure 23, and two notches 34 respectively recessed at the junction of the bottom surface and the side surface of the cover side portion 32; in this embodiment, each of the second connecting structures 33 includes an insertion portion 331 protruding downward from the bottom surface of the cover side portion 32 and detachably inserted into the connecting groove 231, and a positioning protrusion 332 protruding from the side of the insertion portion 331 and positioned in the positioning hole 232 (as shown in FIG5), but not limited thereto, the insertion portion 331 and the positioning protrusion 332 may also be concave. The second connecting structure 33 of the link cover 30 and the first connecting structure 23 of the link seat 20 can be in a concave-convex fit. In addition, the link cover 30 also has a second locking part 35 connecting the top of the cover 31, and the side 351 of the second locking part 35 and the top surface 311 of the top of the cover 31 form an obtuse angle θ, so that the second locking part 35 is slightly inclined from bottom to top in the right direction of Figure 4, forming a structure that is thinner at the bottom and thicker at the top. At the same time, the second locking part 35 has two second locking holes 352 for locking onto the slide 91 (as shown in Figure 6). Through the slightly inclined structural design of the second locking part 35, it has a spring-loaded effect, making the link cover 30 more securely locked onto the slide 91 and easier to detach from the slide 91 when disassembling.

[0017] The above description constitutes an explanation of the main components of the first embodiment of the present invention. The operation and effects of the present invention are explained below:

[0018] Referring to Figures 2 and 3, when the link seat 20 and the link cover 30 are combined, firstly, the two insertion portions 331 of the link cover 30 are aligned with the two engagement grooves 231 of the link seat 20. Then, the link cover 30 is pressed down towards the link seat 20, so that the insertion portions 331 are inserted into the engagement grooves 231, and the positioning protrusion 332 is positioned in the positioning hole 232 (as shown in Figure 5), thereby completing the assembly of the link seat 20 and the link cover 30 to form an annular channel A for protecting the cable 92 or pipeline. Finally, referring to Figure 6, the first locking portion 24 of the link seat 20 and the second locking portion 35 of the link cover 30 are locked to the side of the slide 91 to protect the cable 92 or pipeline.

[0019] Referring to Figures 4, 6 and 7, when it is necessary to replace or repair the cable 92 or pipeline in the cable protection chain, in addition to removing the upper guard plate 961 of the other links 96 of the cable protection chain, the link cover 30 can also be removed from the slide 91 and the link seat 20. The link cover 30 can be removed from the link seat 20 by, but is not limited to, inserting a flathead screwdriver (not shown in the figure) into the notch 34 of the link cover 30, and then turning the screwdriver upwards to remove the link cover 30 from the link seat 20. At this time, the cable 92 or pipeline can be repaired or replaced.

[0020] Accordingly, the present invention uses the first coupling structure 23 of the link seat 20 and the second coupling structure 33 of the link cover 30 to make the link seat 20 and the link cover 30 detachable from each other. Therefore, when it is necessary to replace or repair the cable 92 or pipeline in the cable protection chain, the cable 92 or pipeline can be removed from the link after the link cover 30 is removed from the link seat 20, so as to carry out repair or replacement, thus having the effect of convenient repair and replacement.

[0021] Referring to Figure 8, the detachable cable protection chain structure provided in the second embodiment of the present invention is also composed of a chain link seat 20 and a chain link cover 30, but differs from the first embodiment in that:

[0022] The link seat 20 extends rearward from each of the seat side portions 22 to form an inner pivot portion 26, that is, the two inner pivot portions 26 are in a face-to-face state, so as to pivotally connect different types of links. [Simplified Explanation of the Diagram]
