Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to a foldable wire and cable tube. Background Art

[0002] The power cable protection tube refers to a metal protection tube with a certain mechanical strength that is laid on the outer layer of the cable to prevent the cable from being damaged. The power cable protection tube is mainly installed in the area where the communication cable and the power line intersect to prevent the power line from being broken and causing a short circuit accident, causing the communication cable and wire rope to be energized, so as to protect the cable, switch, movement board, and even the whole machine from being burned out, and it also plays a certain isolation role in the magnetic field interference of the power line.

[0003] In the prior art, for example, the Chinese patent number is: CN117638758A, which is a foldable wire and cable protection tube, and relates to the field of cable protection technology. The foldable wire and cable protection tube includes two protection tube bodies, and the protection tube body includes a first connecting tube body, one end of the first connecting tube body is fixedly connected to an extended movable tube body, and the outer surface of the extended movable tube body is slidably connected to a second connecting tube body. Loosen the limit nut, and the first fixed connecting block and the corresponding second fixed connecting block can be rotated at this time, so that the first connecting tube body and the second connecting tube body in another protective tube body can be folded to adjust the angle. After the adjustment is completed, loosen the third locking bolt, adjust the length between the second fixed connecting rod and the extended mounting rod body, and then tighten the third locking bolt, and then thread the second locking bolt with the corresponding threaded hole on the side wall of the connecting mounting block. At this time, the fixation after the angle adjustment can be completed, which is suitable for non-straightly laid wires and cables and has strong practicality.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that although it can adjust the length between the second fixed connecting rod and the extended mounting rod body by loosening the third locking bolt, and then tightening the third locking bolt, and then threading the second locking bolt with the corresponding threaded hole on the side wall of the connecting mounting block, the fixation after angle adjustment can be completed at this time, but at this time, a triangle state is formed between the adjacent first connecting tube body, second connecting tube body, first fixed connecting rod, second fixed connecting rod and extended mounting rod body, so that when the protective tube is laid on the ground, it needs to occupy a larger area, and when the wires and cables need to be laid in a bend, part of the reason may be that due to terrain restrictions, they cannot be laid in a straight line, which makes the laying of the protective tube more troublesome and has lower applicability.

[0008] Preferably, the two clamping mechanisms include a plurality of movable rods, and the outer surfaces of the plurality of movable rods are symmetrically and movably embedded in the outer surface of the two protective tubes near one end in pairs. A clamping block is fixedly installed at one end of the plurality of movable rods, and the outer surfaces of the plurality of clamping blocks are symmetrically and movably embedded in the inner wall of the two protective tubes in pairs.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] 1. The present invention pulls the limiting rod outward by hand to disengage it from the inside of the limiting hole, and simultaneously stretches the compression spring to release the limiting of the disc 2. At this time, one of the groups of protection tubes 1 and 2 can be pushed to make the disc 2 rotate around the outer surface of the connecting shaft. When it rotates to a suitable distance, the limiting rod is released again to insert it into the limiting hole under the restoring force of the compression spring to limit the disc 2. The two groups of protection tubes 1 and 2 can be kept in a relatively fixed state. In this way, when the two groups of protection tubes 1 and 2 are folded and laid at a certain angle, they do not need to occupy a large area, thereby facilitating the laying of the protection tubes 1 and 2, thereby improving the applicability of the device.

[0018] 2. The present invention makes the support plate contact with the ground, and then presses the second protective tube downward, so that the two adjacent movable bars rotate in opposite directions around the outer surface of the third fixed rod, so that the distance between the bottom and the top of the two adjacent movable bars gradually increases, so that the support plate slides on the ground, and with the cooperation of the rotating rod, the support plate can always fit the ground. Through the rotation of the movable bar, a force can be applied to the round rod three and the L-shaped bar, so that the L-shaped bar rotates around the outer surface of the second round rod, so that the third round rod slides appropriately inside the second movable groove, and the L-shaped bar is synchronously used to rotate the round rod one. A force is applied to make the movable rod slide toward the inside of the second protective tube, driving the clamping block to clamp and fix the wires and cables, and simultaneously making the round rod one slide appropriately inside the movable groove one. Through the setting of the elastic rubber pad, a certain protective effect can be played on the wires and cables, and under the action of the gravity of the first and second protective tubes and the wires and cables themselves, the clamping effect of the clamping block on the wires and cables can be guaranteed. In this way, when the wires and cables are laid, the wires and cables can be prevented from being pulled out of the first and second protective tubes, thereby improving the protection effect of the wires and cables.

[0019] 3. The present invention fixes the support plate by passing the insertion rod through the support plate and inserting it into the soil, thereby fixing the protection tube 1 and the protection tube 2. Due to the rotation of the movable bar, the distance between the two relative support plates becomes longer, so that the support plate has a better supporting effect on the protection tube 2 and the protection tube 1. In this way, the position displacement of the protection tube 1 and the protection tube 2 can be avoided after the laying is completed, thereby ensuring the overall effect of the laying of the wires and cables.

At this time, the protection tube 2 2 can be slid along the outer surface of the protection tube 1, and can be appropriately adjusted according to the length of the wire and cable. The locking bolt 201 is then rotated in the opposite direction to make it press against the outer surface of the protection tube 1, so that the protection tube 1 and the protection tube 2 2 can be relatively fixed. The limiting ring 4 is then set to limit the protection tube 1 to prevent the protection tube 1 from colliding with the clamping mechanism 3.

[0031] Embodiment 2, as Figure 1 - Figure 6As shown, the two clamping mechanisms 3 include a plurality of movable rods 301, the outer surfaces of the plurality of movable rods 301 are symmetrically and movably embedded in the outer surfaces of the two protective tubes 2 near one end, one end of the plurality of movable rods 301 is fixedly installed with a clamping block 304, the outer surfaces of the plurality of clamping blocks 304 are symmetrically and movably embedded in the inner wall of the protective tube 2, the outer surfaces of the two protective tubes 2 near the movable rod 301 are symmetrically and fixedly installed with two fixing bars 306, a side of the plurality of fixing bars 306 away from the protective tube 2 is fixedly installed with a round rod 2 307, the outer surfaces of the plurality of round rods 2 307 are movably sleeved with an L-shaped bar 308, a side of the plurality of L-shaped bars 308 near the top is provided with a movable groove 1 309, the other end of the plurality of movable rods 301 is fixedly installed with a connecting block 302, and one side of the plurality of connecting blocks 302 is fixedly installed with a round rod 1 303, the outer surfaces of the multiple round rods 303 are movably embedded in the inner walls of the multiple movable grooves 309 respectively, the outer surfaces of the two protective tubes 2 are located below the fixed bar 306 and are symmetrically fixed with two fixed blocks 311, the multiple fixed blocks 311 are evenly divided into two groups, the opposite sides of the two groups of fixed blocks 311 are fixedly installed with fixed rods 312, the outer surfaces of the two fixed rods 312 are staggered and symmetrically movably sleeved with two movable bars 313, the multiple movable bars 313 are provided with movable grooves 2 314 on one side near the top, the multiple fixed bars 306 are fixedly installed with round rods 310 on one side near the bottom, the outer surfaces of the multiple round rods 310 are movably embedded in the inside of the multiple movable grooves 2 314 respectively, the multiple clamping blocks 304 are arranged in an arc shape, and the inner side of the arc surface of the multiple clamping blocks 304 is fixedly installed with elastic rubber pads 305.

[0032] In this embodiment, by making the support plate 316 contact with the ground, and then pressing the protection tube 2 downward, the two adjacent movable bars 313 rotate in opposite directions around the outer surface of the fixed rod 312, so that the distance between the bottom and the top of the two adjacent movable bars 313 gradually becomes longer, so that the support plate 316 slides on the ground, and with the cooperation of the rotating rod 315, the support plate 316 can always fit the ground. Through the rotation of the movable bar 313, a force can be applied to the round rod 310 and the L-shaped bar 308, so that the L-shaped bar 308 rotates around the outer surface of the round rod 2 307, so that the round rod 310 slides appropriately inside the movable groove 2 314, and synchronously passes through The L-shaped bar 308 applies a force to the round rod 303, causing the movable rod 301 to slide toward the inside of the protective tube 2, driving the clamping block 304 to clamp and fix the wires and cables, and simultaneously causing the round rod 303 to slide appropriately inside the movable groove 309. Through the provision of the elastic rubber pad 305, a certain protective effect can be played on the wires and cables. Under the action of the gravity of the protective tube 1 and the protective tube 2 as well as the wires and cables themselves, the clamping effect of the clamping block 304 on the wires and cables can be guaranteed. In this way, when the wires and cables are laid, the wires and cables can be prevented from being pulled out of the protective tube 1 and the protective tube 2, thereby improving the protection effect on the wires and cables.

[0034] In this embodiment, the support plate 316 is fixed by passing the insertion rod 317 through the support plate 316 and inserting it into the soil, so that the protection tube 1 1 and the protection tube 2 2 can be fixed. Due to the rotation of the movable bar 313, the distance between the two relative support plates 316 becomes longer, so that the support plate 316 has a better supporting effect on the protection tube 2 2 and the protection tube 1 1. In this way, the position offset of the protection tube 1 1 and the protection tube 2 2 after laying is completed can be avoided, thereby ensuring the overall effect of the laying of wires and cables.

[0035] Working principle: When in use, first pass the wires and cables through the protection tube 1 and the protection tube 2, and then adjust them according to the angle at which the wires and cables need to be laid. Pull the limit rod 204 outward by hand to make it disengage from the inside of the limit hole 104, and simultaneously stretch the compression spring 205 to release the limit on the disc 203. At this time, one set of protection tube 1 and protection tube 2 can be pushed to make the disc 203 rotate around the outer surface of the connecting shaft 103. When it rotates to a suitable distance, release the limit rod 204 and insert it into the inside of the limit hole 104 under the reset force of the compression spring 205 to limit the disc 203, so that the two sets of protection tubes 1 and 2 can remain in a relatively fixed state. When the protective tube 1 and the protective tube 2 are folded and laid at a certain angle, they do not need to occupy a large area, which makes it convenient to lay the protective tube 1 and the protective tube 2, thereby improving the applicability of the device. By turning the locking bolt 201 by hand, the limit on the protective tube 2 can be released. At this time, the protective tube 2 can be slid along the outer surface of the protective tube 1, and can be appropriately adjusted according to the length of the wire and cable. Then, the locking bolt 201 is rotated in the opposite direction to make it press against the outer surface of the protective tube 1, so that the protective tube 1 and the protective tube 2 can be relatively fixed. Then, through the setting of the limiting ring 4, the protective tube 1 is limited to avoid the collision of the protective tube 1 with the clamping mechanism 3. When the protective tube 1 and the protective tube 2 need to be laid on the ground, By making the support plate 316 contact with the ground, and then pressing the protection tube 2 downward, the two adjacent movable bars 313 rotate in opposite directions around the outer surface of the fixed rod 312, so that the distance between the bottom and the top of the two adjacent movable bars 313 gradually becomes longer, so that the support plate 316 slides on the ground, and with the cooperation of the rotating rod 315, the support plate 316 can always fit the ground, and through the rotation of the movable bar 313, a force can be applied to the round rod 310 and the L-shaped bar 308, so that the L-shaped bar 308 rotates around the outer surface of the round rod 2 307, so that the round rod 310 slides appropriately inside the movable groove 2 314, and simultaneously a force is applied to the round rod 1 303 through the L-shaped bar 308, so that the movable rod 301 moves toward the protection tube 2 2, driving the clamping block 304 to clamp and fix the wires and cables, and synchronously making the round rod 1 303 slide appropriately inside the movable groove 1 309, and through the setting of the elastic rubber pad 305, it can play a certain protective role on the wires and cables, and under the action of the gravity of the protection tube 1 and the protection tube 2 and the wires and cables themselves, the clamping effect of the clamping block 304 on the wires and cables can be guaranteed, so that when the wires and cables are laid, the wires and cables are prevented from being pulled out of the protection tube 1 and the protection tube 2, thereby improving the protection effect of the wires and cables, and finally, the support plate 316 is fixed by passing the insertion rod 317 through the support plate 316 and inserting it into the soil, so that the protection tube 1 and the protection tube 2 can be fixed,Due to the rotation of the movable bar 313, the distance between the two opposite support plates 316 becomes longer, so that the support plate 316 has a better supporting effect on the protection tube 2 2 and the protection tube 1 1, which can avoid the position deviation of the protection tube 1 1 and the protection tube 2 2 after laying, thereby ensuring the overall effect of laying wires and cables.
