Description

Technical Field

[0001] This invention relates to the field of cable protection pipe technology, specifically to a cable protection pipe with a protective structure. Background Technology

[0002] Cable protection pipes are a type of conduit system used to wrap, support, and protect power cables or communication cables. Their main function is to prevent cables from being damaged by external factors such as mechanical damage, environmental corrosion, and animal bites during laying, operation, and maintenance, while also providing cable fixation and path guidance.

[0003] Existing cable protection pipes are generally divided into single pipes and seven-hole clover pipes. For thick cables, single pipes are usually used, while multiple thin cables are usually placed in different pipes of a seven-hole clover pipe. In the process of laying a combination of thick and thin cables, multiple single pipes and multiple seven-hole clover pipes are used in combination, and then multiple protection pipes are placed in a series of pipe supports in an orderly manner.

[0004] A pipe support typically consists of two plates joined together to form a circle. When a seven-hole swivel tube is placed inside the support, the small contact area between the tube and the inner wall makes it prone to shifting and twisting. This can easily cause the thin cable inside to twist, and excessive twisting can damage the cable. Furthermore, the size of the seven-hole swivel tube varies depending on the size of the thin cable. Smaller diameter tubes are more likely to shift inside the support, affecting the cable protection. Summary of the Invention

[0005] The purpose of this invention is to provide a cable protection pipe with a protective structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable protection pipe with a protective structure, comprising a first protection pipe and a second protection pipe, both of which are provided with pipe supports on their exteriors. The top and bottom of the second protection pipe are respectively provided with a first limiting bracket and a second limiting bracket. The ends of the first and second limiting brackets that are close to each other are rotatably connected. Both ends of the first and second limiting brackets are provided with limiting mechanisms. The first and second limiting brackets are provided with a fixing mechanism. An extension plate is fixedly installed on one side of both the first and second limiting brackets. Both extension plates are provided with a connecting mechanism on their exteriors.

[0007] The limiting mechanism includes a limiting block. Two symmetrically arranged connecting rods are fixedly installed on the end of the limiting block away from the second protective tube. A connecting plate is fixedly installed on the side of the two connecting rods away from the limiting block. A spring is fixedly installed on the side of the connecting plate close to the limiting block.

[0008] Preferably, the connecting mechanism includes a first side plate, a second side plate, two L-shaped slides, and two fixing components. The first side plate is fixedly installed at one end of the extension plate. The two L-shaped slides are symmetrically opened at the end of the extension plate away from the first side plate. Both ends of the bottom of the second side plate are fixedly installed with L-shaped sliders. The two L-shaped sliders are slidably installed inside the two L-shaped slides respectively.

[0009] Preferably, the pipe support includes two support plates. Two pin holes are symmetrically provided on the side of the two support plates that are far apart from each other and on the side that are close to each other. Pin holes are provided on both sides of the two support plates. A positioning pin is provided between two adjacent pin holes and between two adjacent pin holes.

[0010] Preferably, the fixing mechanism includes an arc-shaped plate one, an arc-shaped plate two, multiple sets of slots, and an adjustment component. The arc-shaped plate one is slidably fitted inside the limiting bracket one, and the arc-shaped plate two is slidably fitted inside the limiting bracket two. A top rod is fixedly installed on one side of the arc-shaped plate one. Grooves are formed at the ends of the limiting bracket one and the limiting bracket two that are close to each other. Both grooves cooperate with the top rod. The top rod cooperates with the arc-shaped plate two. A spring two is fixedly installed between one side of the arc-shaped plate two and the inner wall of the limiting bracket two. Multiple sets of slots are respectively formed at one end of multiple connecting rods. Two sets of locking strips are fixedly installed at both ends inside the arc-shaped plate one and the arc-shaped plate two. Multiple sets of locking strips cooperate with multiple sets of slots.

[0011] Preferably, the adjusting assembly includes a threaded rod, which is threadedly connected to the top of the limiting bracket. An adjusting block is threadedly connected to the outside of the threaded rod. An adjusting frame is slidably installed on the outside of the adjusting block. The bottom of the adjusting frame is rotatably connected to the arc-shaped plate. Both ends of the adjusting frame are provided with strip grooves. Both ends of the adjusting block are slidably installed inside the two strip grooves. Guide rods are slidably sleeved on both ends of the adjusting block. Both guide rods are fixedly installed inside the limiting bracket.

[0012] Preferably, the fixing component includes a fixing rod and a fixing groove. The fixing groove communicates with a corresponding L-shaped slide groove. The fixing rod and the fixing groove cooperate with each other. The fixing rod is slidably fitted to one end inside the second side plate. A spring is fixedly installed between one side of the fixing rod and the inner wall of the second side plate. A push block is fixedly installed on one side of the fixing rod.

[0013] Preferably, multiple insertion slots are provided on the side of adjacent side plates one and side plates two that are close to each other, and multiple insertion plates are fixedly installed inside both ends of the multiple trays, and the multiple insertion plates cooperate with the multiple insertion slots respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the limiting bracket one and the limiting bracket two are sleeved on the outside of the protective tube two, the multiple limiting blocks are respectively inserted into different positions of the protective tube two. With the help of the fixing mechanism, the multiple limiting blocks are fixed, which solves the problem that the seven-hole plum blossom tube is easy to shake and displace inside the tube support in the existing technology, which can easily cause the twisting of the thin cable inside. This prevents the cable from being damaged by excessive twisting.

[0016] By setting a limiting mechanism consisting of a limiting block, a connecting rod, a connecting plate, and a spring, the limiting block can be adjusted according to the specifications and dimensions of the second protective tube, thus achieving the effect of limiting the seven-hole plum blossom tubes of different diameters. This solves the problem in the existing technology that the seven-hole plum blossom tubes with smaller diameters are more likely to shift inside the tube support, and avoids affecting the protection effect on the cable.

[0017] The two connecting mechanisms allow for quick and easy fixing of the two extension plates, limit bracket one, and limit bracket two to the pipe support. At the same time, it also facilitates the disassembly of limit bracket one and limit bracket two, making it convenient for subsequent replacement of components. Attached Figure Description

[0032] This invention provides a technical solution: such as Figures 1-12 The cable protection pipe shown includes a first protection pipe 1 and a second protection pipe 2. Both the first protection pipe 1 and the second protection pipe 2 are provided with pipe supports on their exteriors.

A connecting plate 11 is fixedly installed on the side of the two connecting rods 10 away from the limiting block 9.

[0034] The connecting mechanism includes a first side plate 25, a second side plate 26, two L-shaped slides 27, and two fixing components. The first side plate 25 is fixedly installed at one end of the extension plate 24. The two L-shaped slides 27 are symmetrically opened at the end of the extension plate 24 away from the first side plate 25. Both ends of the bottom of the second side plate 26 are fixedly installed with L-shaped sliders 28, and the two L-shaped sliders 28 are slidably installed inside the two L-shaped slides 27 respectively.

[0035] The pipe support includes two support plates 3.

Pin holes 5 are opened on both sides of the two support plates 3. A positioning pin 6 is provided between two adjacent pin holes 4 and between two adjacent pin holes 5.

[0036] The fixing mechanism includes an arc-shaped plate 13, an arc-shaped plate 15, multiple sets of slots 17, and an adjustment component. The arc-shaped plate 13 is slidably fitted inside the limiting bracket 7, and the arc-shaped plate 15 is slidably fitted inside the limiting bracket 8. A top rod 14 is fixedly installed on one side of the arc-shaped plate 13. Grooves 35 are opened at the ends of the limiting brackets 7 and 8 that are close to each other. Both grooves 35 cooperate with the top rod 14. The top rod 14 cooperates with the arc-shaped plate 15. A spring 2 16 is fixedly installed between one side of the arc-shaped plate 15 and the inner wall of the limiting bracket 8. Multiple sets of slots 17 are respectively opened at one end of multiple connecting rods 10. Two sets of locking strips 18 are fixedly installed at both ends inside the arc-shaped plate 13 and the arc-shaped plate 15. The multiple sets of locking strips 18 cooperate with the multiple sets of slots 17.

[0037] The adjustment assembly includes a threaded rod 19, which is threadedly connected to the top of the limiting bracket 7. An adjustment block 20 is threadedly connected to the outside of the threaded rod 19. An adjustment frame 21 is slidably installed on the outside of the adjustment block 20. The bottom of the adjustment frame 21 is rotatably connected to the arc plate 13. Both ends of the adjustment frame 21 are provided with strip grooves 22. Both ends of the adjustment block 20 are slidably installed inside the two strip grooves 22. Guide rods 23 are slidably sleeved on both ends of the adjustment block 20. Both guide rods 23 are fixedly installed inside the limiting bracket 7.

[0038] The fixing component includes a fixing rod 31 and a fixing groove 32. The fixing groove 32 is connected to the corresponding L-shaped slide groove 27. The fixing rod 31 and the fixing groove 32 cooperate with each other. The fixing rod 31 is slidably fitted to one end inside the side plate 26. A spring 33 is fixedly installed between one side of the fixing rod 31 and the inner wall of the side plate 26. A push block 34 is fixedly installed on one side of the fixing rod 31.

[0039] Multiple insertion slots 29 are provided on the side of adjacent side plates 1 25 and side plates 26 that are close to each other. Multiple insertion plates 30 are fixedly installed inside both ends of multiple support plates 3, and the multiple insertion plates 30 cooperate with the multiple insertion slots 29 respectively.

[0040] Working principle: When using multiple protective tubes 1 and multiple protective tubes 2 in combination, first lay the support plate 3 from the bottom, insert the positioning pin 6 between the adjacent pin holes 5 to achieve splicing between the left and right support plates 3, then place the protective tubes 1 and 2 inside the support plate 3 in sequence, then lay the multiple support plates 3 on top of the laid support plates 3, and finally insert the positioning pin 6 between the adjacent pin holes 4 to achieve splicing between the upper and lower support plates 3.

[0041] After placing the protective tube 2, which is shaped like a seven-hole plum blossom tube, into the tube support, first, the limiting bracket 7 and the limiting bracket 8 are fitted onto the outside of the protective tube 2. After the limiting bracket 7 and the limiting bracket 8 are in a combined state, the two extension plates 24 are pushed into the tube support. When pushing in the two extension plates 24, the insertion slots 29 on one side of the two side plates 25 need to be aligned with the multiple insertion plates 30 in the support plate 3. Continue to push the two extension plates 24 so that the multiple insertion plates 30 are inserted into their respective insertion slots 29. Then, operate the two connecting mechanisms to connect the two extension plates 24 with the tube support. The operation process of one of the connecting mechanisms is as follows: insert the two L-shaped sliders 28 at the bottom of the side plate 26 into the two L-shaped sliding grooves 27, and push the side plate to one side of the tube support. Side plate 26 moves to its limit position until the two fixing rods 31 correspond to the two fixing slots 32 respectively. At this time, the two fixing rods 31 are inserted into the corresponding fixing slots 32 under the action of their respective springs 33. At this time, the insertion slot 29 on one side of side plate 26 is also sleeved on the outside of the corresponding insertion plate 30, cooperating with side plate 1 25 to fix the position between the extension plate 24 and the pipe support. The operation process of the other connecting mechanism is the same as above, thereby fixing the two extension plates 24 and the limiting bracket 1 7 and limiting bracket 2 8. Through the two connecting mechanisms, the two extension plates 24, the limiting bracket 1 7 and the limiting bracket 2 8 are quickly fixed to the pipe support. At the same time, it is also convenient to disassemble the limiting bracket 1 7 and the limiting bracket 2 8, which facilitates the replacement of subsequent parts.

[0042] When the limiting bracket 1 7 and limiting bracket 2 8 are then fitted onto the outside of the protective tube 2 2, the multiple limiting blocks 9 are engaged in different positions of the protective tube 2 2 under the action of their respective corresponding springs 1 12. The multiple springs 1 12 deform accordingly under the force, and the multiple connecting rods 10 slide inside the limiting brackets 1 7 and limiting bracket 2 8. Subsequently, by rotating the threaded rod 19, the adjusting block 20 moves along the two guide rods 23 under the action of the guide rod 23, thereby driving the adjusting frame 21 to move. As the adjusting frame 21 moves, The arc-shaped plate 13 at its bottom moves synchronously inside the limiting bracket 7. The adjusting frame 21 moves up and down outside the adjusting block 20 through two strip grooves 22. As the arc-shaped plate 13 moves, the top rod 14 on one side moves synchronously. The top rod 14 passes through the groove 35 in the limiting bracket 7 and acts on the arc-shaped plate 15 along the groove 35 in the limiting bracket 8. The arc-shaped plate 15 slides inside the limiting bracket 8 under force and compresses the spring 16. At this time, the arc-shaped plate 13 and the arc-shaped plate 15 move synchronously. The 2nd 15 moves in the same direction, causing multiple sets of locking strips 18 to move synchronously. These locking strips 18 insert into their corresponding slots 17, fixing the multiple connecting rods 10 and thus the multiple limiting blocks 9. When the limiting bracket 1 7 and the limiting bracket 2 8 are fitted onto the outside of the protective tube 2, the multiple limiting blocks 9 are respectively engaged in different positions on the protective tube 2. Combined with the fixing mechanism, this achieves the fixation of the multiple limiting blocks 9, solving the problem of easy shaking and displacement of the seven-hole plum blossom tube inside the tube support in the existing technology. This can easily cause the internal thin cable to twist, thus preventing excessive twisting from damaging the cable. Furthermore, through the limiting mechanism consisting of limiting block 9, connecting rod 10, connecting plate 11, and spring 12, the limiting block 9 can be adjusted according to the specifications of the protective tube 2, achieving the effect of limiting the seven-hole plum blossom tubes of different diameters. This solves the problem in the prior art that the seven-hole plum blossom tubes with smaller diameters are more likely to shift inside the tube support, thus avoiding affecting the protection effect on the cable.
