Description

Technical Field

[0001] The utility model relates to the technical field of leakage cable clamps, in particular to a leakage cable clamp for preventing unclamping. Background Technique

[0002] The wireless system of urban rail transit requires more reliable safety to ensure the safe operation of the line. The laying of leakage cables along the rail transit line has become a key task to ensure smooth communication. A large number of cable clamps are used in the laying construction of various lines to fix the cables on the tunnel wall. How to improve the reliability of cable clamp fixation, the convenience of disassembly and assembly, and the wide applicability, while ensuring the safe operation of trains and fully reflecting the economy of manpower, financial resources and material resources, has always been the goal pursued by people.

[0003] However, there are still deficiencies in the use of leakage cable clamps in the related art. The locking end of the leakage cable clamp in the related art adopts a single-locking elastic buckling method, which not only easily fails to buckle firmly, but even unclamping and flying off may occur, reducing the stability and safety of cable fixation. Therefore, we propose a leakage cable clamp for preventing unclamping to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned drawbacks and propose a leakage cable clamp for preventing unclamping.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A leakage cable clamp for preventing unclamping, including a fixed seat on the leakage cable clamp. The bottom of the fixed seat is fixedly connected with an upper clamping ring. The bottom of the upper clamping ring is rotatably connected with a lower clamping ring. A fixing mechanism for automatically clamping and fixing the cable is arranged between the lower clamping ring and the upper clamping ring. A connecting seat is fixedly connected to one side of the upper clamping ring. A locking tongue is fixedly connected to the bottom of the lower clamping ring. An anti-unclamping mechanism is arranged among the locking tongue, the upper clamping ring and the connecting seat.

[0007] Specifically, a locking groove is opened at the bottom of the upper clamping ring. The anti-unclamping mechanism includes a clamping and fixing component and a locking component. The clamping and fixing component is a lower spring fixedly connected to the inner wall of one side of the connecting seat. One end of the lower spring is fixedly connected with a sliding plate. One side of the sliding plate is fixedly connected with a clamping rod. The locking tongue is movably inserted into the locking groove. A clamping groove is opened on one side of the locking tongue. The clamping rod is movably clamped in the clamping groove. A pulling plate is connected to the top of the sliding plate.

[0008] Specifically, a rectangular opening is formed in the top of the connecting seat, the pulling plate is slidably sleeved in the rectangular opening, a cavity is formed in the pulling plate, the locking assembly includes guide rods fixedly arranged on the inner walls of both sides of the rectangular opening and an upper spring fixedly connected to the inner wall of the top of the cavity, the pulling plate is slidably sleeved on the outer sides of the guide rods, the bottom end of the upper spring is fixedly connected with a moving plate, the bottom of the moving plate is fixedly connected with a locking rod, locking holes are formed in the tops of the guide rods, the locking rod is movably clamped in the corresponding locking holes, and a vertical rod is fixedly connected to the top of the moving plate.

[0009] Specifically, a pulling ball is fixedly connected to the top end of the vertical rod.

[0010] Specifically, the moving plate is slidably sleeved in the cavity, and the upper spring is sleeved on the outer side of the vertical rod.

[0011] Specifically, the fixing mechanism includes two elastic rings, both elastic rings are fixedly connected to the inner wall of the bottom of the lower clamping ring, and the tops of the two elastic rings are fixedly connected with the same arc-shaped clamping plate, and the arc-shaped clamping plate is matched with the upper clamping ring.

[0012] Specifically, a lower rubber pad is fixedly connected to the top of the arc-shaped clamping plate, and two upper rubber pads are fixedly connected to the inner wall of the top of the upper clamping ring.

[0013] Specifically, two fixing holes are formed in the top of the fixing seat, and the two fixing holes are symmetrically distributed based on the fixing seat.

[0014] In the utility model, for the leaky cable clamp with anti-disengagement, through the arrangement of the fixing seat and the fixing holes, it is beneficial to fix the device on the tunnel wall. The cable is placed into the upper clamping ring and abuts against the upper rubber pad. Then, through the arrangement of the pulling ball and the vertical rod, the locking rod can be pulled upward to compress the upper spring. At this time, the locking rod moves upward to disengage from the locking hole and does not fix the pulling plate. At this time, the pulling plate and the sliding plate can be pulled to the right to compress the lower spring. The sliding plate drives the clamping rod to move to the right and retract into the connecting seat without hindering the operator from pressing the lower clamping ring and the locking tongue into the locking groove. When the lower clamping ring is buckled, through the elasticity of the elastic ring, the position of the arc-shaped clamping plate can be adjusted, and thus cables with different diameters can be fixed and used, improving the versatility of the device. Then, the pulling plate is released. At this time, under the elastic force of the lower spring, the clamping rod moves to the left and is clamped in the clamping groove, and thus the locking tongue and the lower clamping ring can be clamped and fixed.

[0015] In the present utility model, for the anti-disengagement leaky cable clamp, in order to prevent disengagement, when the slide plate moves leftward, it drives the pull plate to move leftward and reset to align with the locking hole. At this time, when the pulling ball is released, under the elastic force of the upper spring, the locking rod moves downward and is clamped in the locking hole, thereby achieving the purpose of locking the pull plate, the slide plate and the clamping rod, so that the clamping rod cannot disengage from the card slot to the right, resulting in the inability to firmly fix the locking tongue and the lower snap ring. This greatly improves the stability of the fixation of the lower snap ring and makes the anti-disengagement effect better.

[0016] The structure of the present utility model is reasonably designed. Under the double snap-fastening of the clamping connection between the clamping rod and the card slot and the clamping connection between the locking rod and the locking hole, the locking tongue and the lower snap ring can be firmly fixed, making the anti-disengagement effect better, improving the stability and safety of the cable fixation. Through the fixing mechanism, when the lower snap ring is fastened, the cable with different diameters can be automatically clamped and fixed, improving the practicability of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Reference Figures 1-5 , an anti-disengagement leaky cable clamp, including a fixed seat 1 on the leaky cable clamp. The bottom of the fixed seat 1 is fixedly connected with an upper clamping ring 3. The bottom of the upper clamping ring 3 is rotatably connected with a lower clamping ring 5. A fixing mechanism for automatically clamping and fixing the cable is arranged between the lower clamping ring 5 and the upper clamping ring 3. One side of the upper clamping ring 3 is fixedly connected with a connecting seat 9. The bottom of the lower clamping ring 5 is fixedly connected with a locking tongue 2. An anti-disengagement mechanism is arranged among the locking tongue 2, the upper clamping ring 3 and the connecting seat 9.

[0025] Further, a locking groove 17 is opened at the bottom of the upper clamping ring 3. The anti-disengagement mechanism includes a clamping and fixing component and a locking component. The clamping and fixing component is a lower spring 14 fixedly connected to the inner wall of one side of the connecting seat 9. One end of the lower spring 14 is fixedly connected with a sliding plate 13. One side of the sliding plate 13 is fixedly connected with a clamping rod 16. The locking tongue 2 is movably inserted into the locking groove 17. A clamping groove 19 is opened on one side of the locking tongue 2. The clamping rod 16 is movably clamped in the clamping groove 19. A pulling plate 12 is connected to the top of the sliding plate 13.

[0026] Further, a rectangular opening 18 is opened at the top of the connecting seat 9. The pulling plate 12 is slidably sleeved in the rectangular opening 18. A cavity 24 is opened in the pulling plate 12. The locking component includes a guiding rod 11 fixedly arranged on the inner walls of both sides of the rectangular opening 18 and an upper spring 22 fixedly connected to the inner wall of the top of the cavity 24. The pulling plate 12 is slidably sleeved on the outside of the guiding rod 11. The bottom end of the upper spring 22 is fixedly connected with a moving plate 10. The bottom of the moving plate 10 is fixedly connected with a locking rod 20. A locking hole 21 is opened at the top of the guiding rod 11. The locking rod 20 is movably clamped in the corresponding locking hole 21. A vertical rod 23 is fixedly connected to the top of the moving plate 10. Through the arrangement of the vertical rod 23, the locking rod 20 can be pulled upward to compress the upper spring 22. At this time, the locking rod 20 moves upward to disengage from the locking hole 21 and does not fix the pulling plate 12. At this time, the pulling plate 12 and the sliding plate 13 can be pulled to the right to compress the lower spring 14. The sliding plate 13 drives the clamping rod 16 to move to the right and retract into the connecting seat 9 without hindering the operator from pressing the lower clamping ring 5 and the locking tongue 2 into the locking groove 17. Release the pulling plate 12. At this time, under the elastic force of the lower spring 14, the clamping rod 16 moves to the left and is clamped in the clamping groove 19, and then the locking tongue 2 and the lower clamping ring 5 can be clamped and fixed. In order to prevent the occurrence of disengagement, at the same time, the leftward movement of the sliding plate 13 drives the leftward movement and reset of the pulling plate 12 to align with the locking hole 21. Release the vertical rod 23. At this time, under the elastic force of the upper spring 22, the locking rod 20 moves downward and is clamped in the locking hole 21, so as to lock the pulling plate 12, the sliding plate 13 and the clamping rod 16, so that the clamping rod 16 cannot move to the right to disengage from the clamping groove 19 and cause the locking tongue 2 and the lower clamping ring 5 to be unable to be fixed stably, greatly improving the stability of the fixation of the lower clamping ring 5 and making the anti-disengagement effect better.

[0027] Furthermore, a pulling ball 15 is fixedly connected to the top end of the vertical rod 23. The moving plate 10 is slidably sleeved in the cavity 24, and the upper spring 22 is sleeved on the outer side of the vertical rod 23, which facilitates pulling the vertical rod 23 and can guide the moving plate 10 and the upper spring 22 at the same time, making its movement smoother.

[0028] Furthermore, the fixing mechanism includes two elastic rings 6. Both of the two elastic rings 6 are fixedly connected to the bottom inner wall of the lower clamping ring 5. The same arc-shaped clamping plate 7 is fixedly connected to the tops of the two elastic rings 6. The arc-shaped clamping plate 7 is matched with the upper clamping ring 3. When the lower clamping ring 5 is buckled, the position of the arc-shaped clamping plate 7 can be adjusted through the elasticity of the elastic rings 6, and then cables with different diameters can be fixed and used, improving the versatility of the device.

[0029] Furthermore, a lower rubber pad 8 is fixedly connected to the top of the arc-shaped clamping plate 7, and two upper rubber pads 4 are fixedly connected to the top inner wall of the upper clamping ring 3. Through the arrangement of the upper and lower rubber pads, not only the anti-slip effect is achieved, making the fixing effect better, but also the purpose of buffering and protecting the cable is achieved.

[0030] Furthermore, two fixing holes are formed in the top of the fixing seat 1, and the two fixing holes are symmetrically distributed based on the fixing seat 1. Through the arrangement of the fixing seat 1 and the fixing holes, it is beneficial to fix the device on the tunnel wall.

[0031] In the present utility model, when fixing a cable, through the arrangement of the fixing base 1 and the fixing hole, it is beneficial to fix the device on the tunnel wall. Then, the cable is placed into the upper clamping ring 3 and abuts against the upper rubber pad 4. Then, through the arrangement of the pulling ball 15 and the vertical rod 23, the locking rod 20 can be pulled upward to compress the upper spring 22. At this time, the locking rod 20 moves upward and disengages from the locking hole 21 without fixing the pull plate 12. At this time, the pull plate 12 and the sliding plate 13 can be pulled to the right to compress the lower spring 14. The sliding plate 13 drives the clamping rod 16 to move to the right and retract into the connecting seat 9 without hindering the operator from pressing the lower clamping ring 5 and the locking tongue 2 into the locking groove 17. When the lower clamping ring 5 is buckled, through the elasticity of the elastic ring 6, the position of the arc-shaped clamping plate 7 can be adjusted, so as to fix cables with different diameters, improving the versatility of the device. Then, the pull plate 12 is released. At this time, under the elastic force of the lower spring 14, the clamping rod 16 moves to the left and is clamped in the clamping groove 19, so as to clamp and fix the locking tongue 2 and the lower clamping ring 5. To prevent the occurrence of tripping, at the same time, the leftward movement of the sliding plate 13 drives the leftward movement and reset of the pull plate 12 to align with the locking hole 21. At this time, when the pulling ball 15 is released, under the elastic force of the upper spring 22, the locking rod 20 moves downward and is clamped in the locking hole 21, so as to lock the pull plate 12, the sliding plate 13 and the clamping rod 16, preventing the clamping rod 16 from moving to the right and disengaging from the clamping groove 19, which may lead to the inability to stably fix the locking tongue 2 and the lower clamping ring 5, greatly improving the stability of the fixation of the lower clamping ring 5 and making the anti-tripping effect better. Similarly, when the cable needs to be disassembled, the above steps can be reversed to quickly disassemble the cable from the device, improving the use effect.
