Description

Technical Field

[0001] The present invention relates to the technical field of insulators, and particularly to an insulator wire fixator. Background Art

[0002] An insulator is a special insulating control component that plays an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles. Gradually, many disc-shaped insulators are hung at one end of the high-voltage wire connection tower. It is used to increase the creepage distance and is usually made of glass or ceramic.

[0003] The traditional fixation of insulators and cables mostly adopts a binding method, that is, the aluminum binding wire is wound from the inner side of the insulator neck to the outer side of the left wire, passes over the top of the insulator to the inner side of the right wire; from under the right wire, passes over the outer side of the insulator neck to the inner side of the left wire, and passes over the top of the insulator to the outer side of the right wire to form a cross; the aluminum binding wire is wound from under the right wire to the inner side of the insulator neck, and the two ends of the aluminum binding wire are twisted 3 - 4 times, cut off and flattened. This fixation method is relatively complex, has high requirements for operators, and the insulators are generally located at a high position, so there is a greater risk in high-altitude operations.

[0004] Therefore, the traditional method of fixing insulators and wires can be improved to enable quick and simple fixation of insulators and wires, and avoid the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an insulator wire fixator to solve the above problems.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An insulator wire fixator includes:

[0008] An insulator part, on which a cable groove and an annular groove are provided;

[0009] The annular groove is sleeved by a first sleeve ring and a second sleeve ring, and the first sleeve ring and the second sleeve ring are rotatably connected. A rotating block is rotatably connected to the first sleeve ring, and a sliding groove is provided on the rotating block. The sliding groove is rotatably connected to a connecting rod fixed on the cover plate, and the connecting rod can also be slidably connected to the sliding groove;

[0010] A pressure wire groove matching the cable groove is provided on the cover plate, and a first fixing rod and a second fixing rod are fixed at the end of the cover plate. Through holes one and two adapted to the first fixing rod and the second fixing rod are respectively provided on the first sleeve ring and the second sleeve ring, and a limiting member for limiting the first fixing rod and the second fixing rod is provided on the first sleeve ring.

[0011] Preferably, the limiting member includes a first sliding hole and a second sliding hole formed in the first collar, and the first sliding hole and the second sliding hole are slidably connected to a first cross bar and a second cross bar fixed to the pulling block. A first clamping block and a second clamping block are respectively fixed on the first cross bar and the second cross bar. A first clamping groove and a second clamping groove adapted to the first clamping block and the second clamping block are respectively formed on the first fixing rod and the second fixing rod. The cover plate is further provided with a cooperating member cooperating with the pulling block to keep the first fixing rod and the second fixing rod stable.

[0012] Preferably, the cooperating member includes a round rod slidably connected to the cover plate. One end of the round rod is fixed with a handle, and the other end is fixed with a connecting block. The connecting block is also slidably connected to the cover plate. A side block is fixed on the connecting block. An inclined groove slidably connected to the side block is formed on the pulling block, and a transverse groove cooperating with the inclined groove is further formed on the pulling block. A second spring is sleeved on the first cross bar, and a third spring is sleeved on the second cross bar. One end of the second spring is fixedly connected to the inner wall of the bent portion of the first collar, and the other end is fixedly connected to the first clamping block. One end of the third spring is fixedly connected to the inner wall of the bent portion of the first collar, and the other end is fixedly connected to the second clamping block. A first spring is sleeved on the round rod.

[0013] Preferably, the connecting block is L-shaped, and one end of the connecting block is slidably connected to the upper surface of the cover plate, and the other end is slidably connected to the side surface of the cover plate.

[0014] Preferably, the height of the side block on the connecting block is lower than that of the first fixing rod and the second fixing rod. That is, when the first fixing rod and the second fixing rod respectively extend into the first through hole and the second through hole, the side block first contacts the inclined groove formed on the pulling block. As the cover plate continuously approaches the first collar and the second collar, the side block, the first fixing rod and the second fixing rod also continuously move downward, and the side block will push the pulling block to move, so that the pulling block moves away from the side wall of the first collar, that is, the first fixing rod and the second fixing rod will not contact the first clamping block and the second clamping block during the downward movement until the cover plate fits with the first collar and the second collar and the first fixing rod and the second fixing rod cannot continue to move downward, and the side block just reaches the transverse groove.

[0015] Preferably, a gasket protrudes on the part of the wire pressing groove in contact with the cable.

[0016] Preferably, a positioning groove is formed on the insulator member, and a positioning block adapted to the positioning groove is fixed to the bottom of the cover plate.

[0017] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0018] 1. In the present application, the first collar and the second collar can clamp the annular groove during rotation, so that the first collar and the second collar are fixed to the insulator as a whole. The cable in the cable groove can be firmly fixed by the cover plate. When the first fixing rod and the second fixing rod at the bottom of the cover plate penetrate through the first through hole and the second through hole, the first clamping block and the second clamping block will extend into the first clamping groove and the second clamping groove under the elastic force of the second spring and the third spring, resulting in the position of the cover plate being fixed. Then, the cover plate can stably exert the effect of firmly fixing the cable. This process is relatively simple, and the staff can quickly get started with the operation.

[0019] 2. In the present application, since the connecting block is slidably connected to the upper surface and the side surface of the first collar, the connecting block cannot rotate. At this time, the pulling block cannot be forced to move, resulting in the first clamping block and the second clamping block disengaging from the first clamping groove and the second clamping groove. Therefore, the cover plate can stably maintain its position, effectively preventing non-professionals from disassembling the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1 - 7 , the present invention provides a technical solution:

[0031] An insulator wire fixer includes:

[0032] An insulator component 1, on which a cable groove 2 and an annular groove 4 are provided, which is a direct reference to the prior art and will not be elaborated here;

[0033] The annular groove 4 is sleeved by a first collar 5 and a second collar 6, and the first collar 5 and the second collar 6 are rotatably connected. A rotating block 7 is rotatably connected to the first collar 5, and a chute 8 is provided on the rotating block 7. The chute 8 is rotatably connected to a connecting rod 10 fixed on the cover plate 9, and the connecting rod 10 can also be slidably connected to the chute 8; A positioning groove 3 is provided on the insulator component 1, and a positioning block 12 adapted to the positioning groove 3 is fixed at the bottom of the cover plate 9. With the cooperation of the positioning block 12 and the positioning groove 3, the positions of the first collar 5 and the second collar 6 can be fixed, which results in the position of the cover plate 9 being fixed. Therefore, even if the first collar 5 and the second collar 6 are subjected to external forces, they will not rotate in the annular groove 4;

[0034] A cable pressing groove 11 cooperating with the cable groove 2 is provided on the cover plate 9. A gasket protrudes from the part of the cable pressing groove 11 in contact with the cable, and a first fixing rod 13 and a second fixing rod 14 are fixed at the end of the cover plate 9. A first through hole 22 and a second through hole 23 adapted to the first fixing rod 13 and the second fixing rod 14 are respectively provided on the first collar 5 and the second collar 6, and a limiting member for limiting the first fixing rod 13 and the second fixing rod 14 is provided on the first collar 5.

[0035] Specifically, asFigure 1 As shown, the limiting member includes a first sliding hole 24 and a second sliding hole 25 formed in the first collar 5, and the first sliding hole 24 and the second sliding hole 25 are slidably connected to a first cross bar 27 and a second cross bar 28 fixed on the pulling block 26. A first clamping block 31 and a second clamping block 32 are respectively fixed on the first cross bar 27 and the second cross bar 28. A first clamping groove 15 and a second clamping groove 16 adapted to the first clamping block 31 and the second clamping block 32 are respectively formed on the first fixing rod 13 and the second fixing rod 14. A cooperating member cooperating with the pulling block 26 is further provided on the cover plate 9, so that the first fixing rod 13 and the second fixing rod 14 are kept stable.

[0036] Specifically, as Figure 1 and Figure 7 shown, the cooperating member includes a round rod 17 slidably connected to the cover plate 9. One end of the round rod 17 is fixed with a handle 18, and the other end is fixed with a connecting block 20. The connecting block 20 is also slidably connected to the cover plate 9. A side block 21 is fixed on the connecting block 20. An inclined groove 33 slidably connected to the side block 21 is formed on the pulling block 26, and a transverse groove 34 cooperating with the inclined groove 33 is further formed on the pulling block 26. A second spring 29 is sleeved on the first cross bar 27, and a third spring 30 is sleeved on the second cross bar 28. One end of the second spring 29 is fixedly connected to the inner wall of the bent part of the first collar 5, and the other end is fixedly connected to the first clamping block 31. One end of the third spring 30 is fixedly connected to the inner wall of the bent part of the first collar 5, and the other end is fixedly connected to the second clamping block 32. A first spring 19 is sleeved on the round rod 17. The connecting block 20 is L-shaped, and one end of the connecting block 20 is slidably connected to the upper surface of the cover plate 9, and the other end is slidably connected to the side surface of the cover plate 9.

[0037] The height of the side block 21 on the connecting block 20 is lower than that of the first fixing rod 13 and the second fixing rod 14, that is, when the first fixing rod 13 and the second fixing rod 14 respectively extend into the first through hole 22 and the second through hole 23, the side block 21 first contacts the inclined groove 33 formed on the pulling block 26.

[0038] As the cover plate 9 continuously approaches the first collar 5 and the second collar 6, the side block 21, the first fixing rod 13 and the second fixing rod 14 also continuously move downward, and the side block 21 will push the pulling block 26 to move, so that the side wall of the pulling block 26 away from the first collar 5. That is, it causes the first fixing rod 13 and the second fixing rod 14 not to contact the first clamping block 31 and the second clamping block 32 during the downward movement until the cover plate 9 fits with the first collar 5 and the second collar 6, and when the first fixing rod 13 and the second fixing rod 14 cannot continue to move downward, the side block 21 just reaches the transverse groove 34.

[0039] In summary, after the first collar 5 and the second collar 6 provided in this embodiment are rotated and opened, they are sleeved on the annular groove 4 formed on the insulator member 1. The first collar 5 and the second collar 6 are rotated so that the first collar 5 and the second collar 6 clamp the annular groove 4.

[0040] Subsequently, the cover plate 9 can be rotated so that the cover plate 9 is parallel to the upper surface of the insulator member 1. Push the cover plate 9 downward. The connecting rod 10 on the cover plate 9 is slidably connected to the chute 8 until the wire pressing groove 11 on the cover plate 9 presses the wire at the wire groove 2 tightly.

[0041] At the same time, as the cover plate 9 moves downward close to the upper surface of the insulator member 1, the side block 21 on the connecting block 20 moves downward accordingly. The side block 21 is slidably connected to the inclined groove 33. Since the side block 21 can only move in the vertical direction. Therefore, during the downward movement of the side block 21, it will push the pulling block 26 to move through the inclined groove 33, that is, the pulling block 26, the first cross bar 27 and the second cross bar 28 move together, and the second spring 29 and the third spring 30 are compressed. Until the first locking block 31 and the second locking block 32 move close to the edge bending part of the first collar 5 and the side block 21 is about to align with the horizontal groove 34.

[0042] When the cover plate 9 continues to move close to the insulator member 1, the first fixing rod 13 and the second fixing rod 14 on the cover plate 9 are slidably connected to the first through hole 22 and the second through hole 23. The positioning block 12 at the bottom of the cover plate 9 is engaged with the positioning groove 3 opened on the insulator member 1, and the cover plate 9 abuts against the upper surface of the insulator member 1. Then at this time, the first locking block 31 and the second locking block 32 are respectively aligned with the first locking groove 15 and the second locking groove 16 opened on the first fixing rod 13 and the second fixing rod 14.

[0043] When the side block 21 moves to the horizontal groove 34, under the elastic force of the second spring 29 and the third spring 30, the side block 21 moves in the horizontal groove 34 until the side block 21 abuts against the inner side wall of the horizontal groove 34. As the pulling block 26 moves, the first cross bar 27 and the second cross bar 28 move together until the first locking block 31 at the end of the first cross bar 27 and the second locking block 32 at the end of the second cross bar 28 respectively extend into the first locking groove 15 and the second locking groove 16. At this time, the positions of the first fixing rod 13 and the second fixing rod 14 are fixed. That is, the position of the cover plate 9 is fixed. The cover plate 9 cooperates with the first collar 5 and the second collar 6 to fix the wire at the wire groove 2 opened on the insulator member 1. Since the connecting block 20 is slidably connected to the upper surface and the side surface of the first collar 5, the connecting block 20 cannot rotate, and at this time, the pulling block 26 cannot be forced to move to cause the first locking block 31 and the second locking block 32 to disengage from the first locking groove 15 and the second locking groove 16. Therefore, the cover plate 9 can stably maintain its own position.

[0044] When the device needs to be disassembled, the connecting block 20 can be pushed to move by pulling the handle 18, so that the second spring 29 is compressed until the side block 21 on the connecting block 20 disengages from the transverse groove 34. At this time, a force can be applied to the pulling block 26, so that the pulling block 26 moves under the force until the first clamping block 31 and the second clamping block 32 disengage from the first clamping groove 15 and the second clamping groove 16. Subsequently, the staff can lift the cover plate 9 upward, so that the cover plate 9 is away from the insulator part 1, and when the connecting rod 10 contacts the inner top wall of the sliding groove 8, the first fixing rod 13 and the second fixing rod 14 also disengage from the first through hole 22 and the second through hole 23. Subsequently, the cover plate 9 can be rotated so that the cover plate 9 rotates away from the cable. Finally, the first collar 5 and the second collar 6 can be rotated so that the first collar 5 and the second collar 6 disengage from the annular groove 4 formed on the insulator part 1 during rotation.

[0045] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
