Description

Technical Field

[0001] This utility model relates to the field of cable conduits, specifically a high-strength braided pultruded cable conduit. Background Technology

[0002] Cable conduits are pipes used in electrical installations to protect wires and cables, allowing them to be inserted and replaced. They are primarily installed where communication cables cross power lines to prevent short circuits caused by power line breaks, which could energize communication cables and steel ropes, thus protecting cables, switches, circuit boards, and even the entire device from burnout. They also provide some isolation against magnetic field interference from power lines. With the development of power and communication industries, the use of wires and cables has become extremely widespread. However, cables are easily damaged for various reasons, making the use of cable conduits essential.

[0003] According to Chinese Patent No. CN220382698U, a corrosion-resistant cable conduit is disclosed. This utility model utilizes a first fixing ring, a collar, a second fixing ring, and multiple compression blocks. After the second fixing ring is inserted into the collar, the compression blocks move to press against the second fixing ring, thereby connecting the first and second cable conduits. In this method, the movement direction of the compression blocks is perpendicular to the axial direction of the cable conduit, making the movement of the compression blocks more convenient. At the same time, the arrangement of multiple compression blocks prevents the first and second cable conduits from rotating to align the flange holes during the connection process, thus improving the convenience of cable conduit connection.

[0004] Regarding the aforementioned patent content, a connection structure is provided to connect the first cable conduit and the second cable conduit. However, the connection and fixing method requires the use of multiple bolts, and it is cumbersome to tighten the bolts one by one, which takes a lot of time. This makes it inconvenient to quickly connect and fix the first cable conduit and the second cable conduit, and reduces the connection efficiency of the first cable conduit and the second cable conduit. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a high-strength braided pultruded cable conduit to solve the technical problem of the inconvenience of quickly connecting the first cable conduit and the second cable conduit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength braided pultruded cable conduit, comprising a first cable conduit and a second cable conduit. A first fixing ring is installed at one end of the first cable conduit, and a connecting assembly is provided on the first fixing ring. The connecting assembly includes multiple slots opened on one side of the first fixing ring, multiple grooves opened inside the first fixing ring, and a limiting ring sleeved on the outer wall of the first fixing ring. A plug is inserted into the slot, and a locking hole is opened on the plug. A spring is installed inside the groove, and a movable plate is connected to the end of the spring. A clamping rod extending through to the outside of the limiting ring is installed on the side of the movable plate away from the plug. A locking post is installed on the side of the movable plate near the plug. A clamping groove is opened on the inner wall of the limiting ring.

[0007] By adopting the above technical solution, when the clamping rod moves towards the insertion block, it will squeeze the spring, causing the spring to be compressed, and at the same time, it will drive the movable plate and the locking post to move.

[0008] Furthermore, a second fixing ring is installed at one end of the second cable conduit, and one side of the second fixing ring is in contact with one side of the first fixing ring.

[0009] By adopting the above technical solution, it is convenient to connect the second cable conduit and the first cable conduit.

[0010] Furthermore, a sealing groove is provided on one side of the first fixing ring, and a sealing gasket is fixed on one side of the second fixing ring.

[0011] By adopting the above technical solution, when the second cable conduit is connected to the first cable conduit, the sealing gasket can be inserted into the sealing groove, thereby improving the sealing performance.

[0012] Furthermore, the sealing gasket is located inside the sealing groove, the sealing gasket is adapted to the sealing groove, and the sealing gasket is made of rubber material.

[0013] By adopting the above technical solution, the sealing gasket can improve the sealing performance between the second cable conduit and the first cable conduit.

[0014] Furthermore, the insert is mounted on one side of the second fixing ring, and the insert is adapted to the slot.

[0015] By adopting the above technical solution, the second cable conduit and the first cable conduit can be positioned after the insert block is inserted into the slot.

[0016] Furthermore, one end of the locking pin is located inside the locking hole, and the locking pin is adapted to the locking hole.

[0017] By adopting the above technical solution, once the locking pin is inserted into the locking hole, the insertion block can be locked and limited, thus completing the connection between the second cable conduit and the first cable conduit.

[0018] Furthermore, both the outer wall of the first fixing ring and the inner wall of the limiting ring are threaded, and the limiting ring is threadedly connected to the first fixing ring.

[0019] By adopting the above technical solution, when rotating the limiting ring, the limiting ring can move on the first fixed ring, thereby adjusting the position of the limiting ring.

[0020] Furthermore, the end of the abutting rod near the limiting ring is set at an angle, and one end of the abutting rod is in contact with the inner wall of the abutting groove.

[0021] By adopting the above technical solution, the limiting ring can tighten and limit the clamping rod, preventing the clamping rod from popping up at will.

[0022] Furthermore, the locking pin is slidably connected to the groove via a movable plate.

[0023] By adopting the above technical solution, the movable plate can slide inside the groove and drive the locking pin to move.

[0024] Furthermore, the outer wall of the limiting ring is equipped with multiple anti-slip protrusions.

[0025] By adopting the above technical solution, it is convenient for workers to rotate the limiting ring through the anti-slip protrusion, so that the limiting ring can move on the first fixed ring.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, by providing a connecting component, allows the operator to insert the plug on the second fixing ring into the slot when connecting the first and second cable conduits. After the first and second fixing rings are in contact, the locking pin aligns with the locking hole. The operator can then rotate the limiting ring, causing it to move. The limiting ring pushes the clamping rod towards the plug, simultaneously moving the movable plate and locking pin, and compressing the spring. When the locking pin is engaged in the locking hole, it can lock and limit the plug, preventing the first and second fixing rings from separating. This completes the connection between the first and second cable conduits. This connection method eliminates the need to rotate multiple bolts to achieve the limiting effect, simplifying the operation and improving the efficiency of connecting the first and second cable conduits.

[0028] 2. This utility model is equipped with anti-slip protrusions, which make it convenient for workers to rotate the limiting ring by means of the anti-slip protrusions. Also, because the end of the clamping rod near the limiting ring is set at an angle, one end of the clamping rod is in contact with the inner wall of the clamping groove, so that the clamping rod can be pushed to move when the limiting ring moves.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A high-strength braided pultruded cable conduit, such as Figures 1-6As shown, the cable conduit includes a first cable conduit 1 and a second cable conduit 2. Both are made of alkali-free glass fiber impregnated with unsaturated polyester resin through braiding, winding, and pultrusion, thereby improving the strength of the cable conduit. For details, refer to the existing patent CN216751055U. A first fixing ring 3 is installed at one end of the first cable conduit 1, and a connecting component 5 is provided on the first fixing ring 3. The connecting component 5 includes multiple slots 510 formed on one side of the first fixing ring 3, multiple grooves 504 formed inside the first fixing ring 3, and a limiting ring 501 sleeved on the outer wall of the first fixing ring 3. An insert block 509 is inserted inside the groove 504, and a locking hole 508 is provided on the insert block 509. A spring 506 is installed inside the groove 504, and a movable plate 505 is connected to the end of the spring 506. A pressing rod 503 is installed on the side of the movable plate 505 away from the insert block 509, which extends to the outside of the limiting ring 501. A locking post 507 is installed on the side of the movable plate 505 close to the insert block 509. A pressing groove 502 is provided on the inner wall of the limiting ring 501. When the pressing rod 503 moves toward the insert block 509, it will squeeze the spring 506, causing the spring 506 to be compressed. At the same time, it will drive the movable plate 505 and the locking post 507 to move.

[0040] See Figures 2-6 The locking post 507 is slidably connected to the groove 504 via the movable plate 505. The movable plate 505 can slide inside the groove 504 and drive the locking post 507 to move. The outer wall of the limiting ring 501 is equipped with multiple anti-slip protrusions 511, which facilitates the operator to rotate the limiting ring 501 through the anti-slip protrusions 511, so that the limiting ring 501 can move on the first fixed ring 3. One end of the second cable conduit 2 is equipped with a second fixed ring 4, and one side of the second fixed ring 4 is in contact with one side of the first fixed ring 3. The insert 509 is installed on one side of the second fixed ring 4. The insert 509 is adapted to the slot 510. When the insert 509 is inserted into the slot 510, the second cable conduit 2 and the first cable conduit 1 can be positioned.

[0041] Specifically, one end of the locking pin 507 is located inside the locking hole 508. The locking pin 507 is adapted to the locking hole 508. When the locking pin 507 is inserted into the locking hole 508, the insert block 509 can be locked and limited, thus completing the connection between the second cable conduit 2 and the first cable conduit 1. The outer wall of the first fixing ring 3 and the inner wall of the limiting ring 501 are both threaded. The limiting ring 501 is threadedly connected to the first fixing ring 3, so that when the limiting ring 501 is rotated, the limiting ring 501 can move on the first fixing ring 3, thereby adjusting the position of the limiting ring 501. The end of the abutting rod 503 near the limiting ring 501 is set with an inclined surface. One end of the abutting rod 503 is in contact with the inner wall of the abutting groove 502. The limiting ring 501 can abut and limit the abutting rod 503 to prevent the abutting rod 503 from popping up at will.

[0042] Example 2:

[0043] Based on the above embodiment 1, in order to improve the sealing performance at the connection between the second cable conduit 2 and the first cable conduit 1, the following structure will be provided.

[0044] See Figures 2-4 A sealing groove 7 is provided on one side of the first fixing ring 3, and a sealing gasket 6 is fixed on one side of the second fixing ring 4. When the second cable conduit 2 is connected to the first cable conduit 1, the sealing gasket 6 can be inserted into the sealing groove 7. The sealing gasket 6 is located inside the sealing groove 7 and is adapted to the sealing groove 7. The sealing gasket 6 is made of rubber material. The setting of the sealing gasket 6 can improve the sealing between the second cable conduit 2 and the first cable conduit 1.

[0045] The working principle of this utility model is as follows: First, when it is necessary to connect the first cable conduit 1 and the second cable conduit 2, the operator can insert the plug 509 on the second fixing ring 4 into the slot 510. When the first fixing ring 3 and the second fixing ring 4 are in contact, the locking post 507 is aligned with the locking hole 508. Then, the operator can rotate the limiting ring 501 to move the limiting ring 501. The limiting ring 501 can push the clamping rod 503 to move towards the plug 509. At the same time, it will drive the movable plate 505 and the locking post 507 to move. The movable plate 505 squeezes the spring 506, so that the spring 506 is compressed. When the locking post 507 is inserted into the locking hole 508, the plug 509 can be locked and limited to prevent the first fixing ring 3 and the second fixing ring 4 from separating. In this way, the connection of the first cable conduit 1 and the second cable conduit 2 can be completed. The first cable conduit 1 and the second cable conduit 2 are made of alkali-free glass fiber impregnated with unsaturated polyester resin through weaving, winding and pultrusion, thereby improving the strength of the cable conduit.
