Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and relates to a quick fixing device for porcelain insulator conductors. Background Technology

[0002] For current line work involving overhead line work, it is necessary to bind the conductors to the insulators. In the current operation, the worker holds the conductor with one hand and uses wire to fix the conductor to the insulator. This often results in the conductor not being bound securely or the binding becoming loose, requiring rebinding, which often consumes a lot of time to complete this task.

[0003] Therefore, in order to overcome the shortcomings of the existing technology, it is necessary to design a simple ceramic bottle wire fast fixing device. Utility Model Content

[0004] This invention provides a quick fixing device for ceramic insulator wires to solve the problems of the prior art.

[0005] The purpose of this utility model can be achieved through the following technical solution: A quick fixing device for ceramic insulator wires includes: a lower cover, an upper cover, ceramic insulator claws, and a rubber pressure plate. The ceramic insulator claws are symmetrically arranged and have a metal rod at the upper end. The rubber pressure plate is inserted into the inner side of the corresponding ceramic insulator claw. The upper cover is rotatably set on the upper end of the lower cover. The upper cover has two sets of arc-shaped sliding grooves in the middle. An elastic lever is provided on the inner side of the arc-shaped sliding groove. The lower end of the metal rod is slidably set in the sliding groove of the lower cover and the upper end is placed in the arc-shaped sliding groove. The inner side of the lower cover has a non-reverse groove that matches the elastic lever for engagement.

[0006] In a further improvement, two sets of anti-reverse grooves and elastic levers are symmetrically arranged. The elastic lever includes an elastic element and a locking rod. The inner side of the elastic element is provided with a clearance groove. The locking rod is fixed to the front end of the elastic element. The end of the locking rod is engaged in the anti-reverse groove. The locking rod and the anti-reverse groove have the same inclined guide surface. The distance between the center of the arc-shaped slide groove and the center of the upper cover is increased in the counterclockwise direction. The anti-reverse groove is disconnected in the middle.

[0007] In a further improvement, the inner side of the lower cover is provided with a rotating groove, the rotating groove is located above the sliding groove and has a break opening, and the inner side of the upper cover is provided with a limiting block that matches the inner side of the rotating groove.

[0008] In a further improvement, the chute has a cross-section resembling a racetrack trough, the upper end of the metal rod has a cross-sectional diameter larger than the width of the chute, the lower end of the metal rod passes through the chute and is inserted into the guide hole of the ceramic bottle clamp, and the upper and lower ends are fixedly connected by threads.

[0009] In a further improvement, four sets of dovetail-shaped inserts are provided on both sides of the bottom of the lower cover. The dovetail-shaped inserts are located on both sides of the slide groove, and two sets of dovetail-shaped slide grooves matching the dovetail-shaped inserts are provided at the upper end of the porcelain bottle clamp.

[0010] In a further improvement, a protrusion is provided in the middle of the inner side of the porcelain bottle clamp, and two sets of symmetrically arranged insertion holes are provided on the inner side of the porcelain bottle clamp. The insertion holes are located on the outer side of the protrusion, and a groove matching the protrusion is provided in the middle of the outer side of the rubber pressure plate. An insertion rod matching the insertion hole is provided on the outer side of the rubber pressure plate.

[0011] In a further improvement, the upper cover is provided with a backflow preventer switch, the lower end of which is fixed with a bolt, and the bottom of the lower cover is provided with a nut. The bolt passes through the center hole of the upper and lower covers and is connected to the nut of the lower cover.

[0012] Compared with the prior art, the advantages of this utility model's rapid fixing device for ceramic insulator wires are as follows:

[0013] By rotating the top cover, the arc-shaped groove inside the top cover causes the metal rod to slide within the groove inside the bottom cover. Simultaneously, this causes the two sets of ceramic grippers below to move inward and clamp the ceramic bottle. At the same time, the synchronously moving rubber pressure plate pushes the wire tightly into the groove of the ceramic bottle, achieving rapid clamping and installation of the wire on the ceramic bottle, improving the efficiency of the construction operation. Meanwhile, the elastic lever inside the top cover, in conjunction with the anti-reverse groove inside the bottom cover, enables the ceramic grippers below to move in one direction, preventing loosening and retraction. The anti-reverse switch locks the position of the top cover on the bottom cover, further improving the stability and clamping effect. At the same time, the rotation of the elastic lever in the initial state does not engage with the anti-reverse groove, preventing accidental tightening and preventing retraction, allowing the ceramic bottle grippers to extend and retract a certain distance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The following is a description of the embodiments and appendices. Figures 1 to 8 The technical solution of this utility model will be further described below.

[0026] Example 1

[0027] A quick-fixing device for ceramic insulator wires includes: a lower cover 1, an upper cover 2, a check switch 3, ceramic insulator grippers 4, and a rubber pressure plate 5. The ceramic insulator grippers 4 are symmetrically arranged and each has a metal rod 41 at its upper end. The lower end of the metal rod 41 is slidably disposed within a groove 11 of the lower cover 1, and the upper end of the metal rod 41 is located above the groove 11. The rubber pressure plate 5 is inserted into the inner side of the corresponding ceramic insulator gripper 4. The upper cover 2 is rotatably disposed above the lower cover 1. The middle portion of the upper cover 2... Two sets of arc-shaped sliding grooves 22 are provided. An elastic lever 21 is provided on the inner side of the arc-shaped sliding groove 22. The distance between the center of the arc-shaped sliding groove 22 and the center of the upper cover 2 increases in the counterclockwise direction. The upper end of the metal rod 41 is placed in the arc-shaped sliding groove 22. The inner side of the lower cover 1 is provided with a backstop groove 12 that matches the elastic lever 21. The backstop groove 12 is disconnected in the middle. The backstop switch 3 is provided on the upper end of the upper cover 2 and is used to clamp and release the lower cover 1 and the upper cover 2.

[0028] like Figures 1-2 As shown, the working principle of this utility model is as follows: The relaxed porcelain bottle clamp 4 is fitted onto the ceramic bottle 8, and the wire 7 is placed in the groove at the upper end of the ceramic bottle 8. The rubber pressure plate 5 is located above the wire 7. Rotating the upper cover 2 clockwise moves the metal rod 41 located in the arc-shaped slide groove 22. Since the distance between the center of the arc-shaped slide groove 22 and the center of the upper cover 2 increases in the counterclockwise direction, the metal rod 41 moves towards the inner side of the arc-shaped slide groove 22. At the same time, the metal rod 41 slides close to the center in the slide groove 11 on the lower cover 1, so that the lower porcelain bottle clamp 4 pre-tightens the ceramic bottle 8, and the porcelain bottle clamp 4 moves inward, causing the rubber pressure plate 5 located on the inner side to... Further tighten the wire 7 to stably fix it to the ceramic insulator 8. The rotation of the upper cover 2 causes the inner elastic lever 21 to be in the middle of the anti-reverse groove 12, where it is not engaged, preventing accidental tightening and preventing it from retracting. This allows the ceramic insulator clamp 4 to extend and retract a certain distance. When the upper cover 2 rotates beyond a certain angle (approximately 45 degrees), it enters the anti-reverse stroke. The front end of the elastic lever 21 engages in the anti-reverse groove 12 and can no longer reset, only continuing to rotate and unable to rotate in the opposite direction. This prevents the upper cover 2 from loosening, thus preventing it from retracting and consequently preventing the ceramic insulator clamp 4 from loosening. Finally, rotating the anti-reverse switch 3 further clamps and fixes the upper cover 2 to the lower cover 1. This wire fixation device enables rapid clamping and installation of wires on ceramic insulators, achieving high-efficiency installation of ceramic insulator wires, reducing the power outage area, shortening the power outage time during construction, and improving the reliability of the power distribution network.

[0029] As a further preferred embodiment, two sets of the anti-reverse groove 12 and the elastic lever 21 are symmetrically arranged. The elastic lever 21 includes an elastic element 211 and a locking rod 212. The elastic element 211 has an inner clearance groove 213. The locking rod 212 is fixed to the front end of the elastic element 211, and the end of the locking rod 212 is engaged in the anti-reverse groove 12. The locking rod 212 and the anti-reverse groove 12 have the same inclined guide surface. Figure 4 and Figure 5 As shown, when the porcelain bottle clamp 4 needs to be tightened, the elastic element 211 has a certain elasticity during the clockwise rotation of the upper cover 2. When the upper cover 2 rotates beyond a certain angle (about 45 degrees), the guide surface of the clamp 212 cooperates with the guide surface of the elastic element 211. When the clamp 212 can be pushed into different anti-reverse tooth grooves 12 in sequence, the clamp 212 needs to rotate a certain angle and avoid a certain distance before it can be pushed into the next anti-reverse tooth groove 12. The elastic element 211 restricts the clamp 212 from rotating within a certain angle. When the clamp 212 is pushed into the anti-reverse tooth groove 12 after being pushed into the designated position, the stability of the clamping is ensured, and the reverse anti-loosening and anti-reverse function is played.

[0030] As a further preferred embodiment, the inner side of the lower cover 1 is provided with a rotating groove 14, the rotating groove 14 is provided with a break opening 15 above the sliding groove 11, and the inner side of the upper cover 2 is provided with a limiting block 23 that matches the inner side of the rotating groove 14. Figure 4 and Figure 5 As shown, the limiting block 23 of the upper cover 2 enters downward along the opening 15, so that the upper cover 2 can move downward relative to the lower cover 1. Then, the limiting block 23 is rotated into the rotating groove 14, which can ensure that the upper cover 2 can rotate within a certain angle range and the lower cover 1 cannot be separated.

[0031] As a further preferred embodiment, the chute 11 has a cross-section resembling a racetrack groove, and the upper end 411 of the metal rod 41 has a cross-sectional diameter larger than the width of the chute 11. The lower end 412 of the metal rod 411 passes through the chute 11 and is inserted into the guide hole 45 of the porcelain bottle clamp 4. The upper end 411 and the lower end 412 are fixedly connected by threads. Figure 5 and Figure 7 As shown, the runway groove 11 is matched with a circular metal rod 41, allowing the metal rod 41 to extend a certain distance along the groove 11 on the limited area of ​​the lower cover 1, thus making the overall design more ingenious. The metal rod 411 has different widths at the top and bottom, and the lower end of the metal rod 411 is inserted into the ceramic bottle clamp 4, ensuring that the ceramic bottle clamp 4 and the lower cover 1 can move relative to each other but cannot detach. The metal rod 41 is connected by threads, and the split design is for easy disassembly during the early design process. Verification shows that a section of the lower end 412 of the printed metal rod 41 can be unscrewed from the ceramic clamp 4, thereby detaching the ceramic clamp 4 from the upper cover 2.

[0032] As a further preferred embodiment, the bottom of the lower cover 1 is provided with four sets of dovetail-shaped inserts 13 on both sides, the dovetail-shaped inserts 13 being located on both sides of the slide groove 11, and the upper end of the porcelain bottle clamp 4 is provided with two sets of dovetail-shaped slide grooves 46 matching the dovetail-shaped inserts 13. Figure 6 and Figure 7 As shown, the dovetail-shaped insert 13 and the dovetail-shaped slide 46 are matched to ensure that the porcelain bottle clamp 4 can only slide horizontally relative to the lower cover 1, restricting vertical and front-back movement, thereby improving the overall stability and adjustment accuracy. At the same time, the four sets of dovetail-shaped inserts 13 can improve the stability of the movement of the two sets of porcelain bottle clamps 4.

[0033] As a further preferred embodiment, the inner center of the porcelain bottle clamp 4 is provided with a protrusion 42, and the inner side of the porcelain bottle clamp 4 is provided with two sets of symmetrically arranged insertion holes 43, the insertion holes 43 being located outside the protrusion 42. The outer center of the rubber pressure plate 5 is provided with a groove 51 matching the protrusion 42, and the outer side of the rubber pressure plate 5 is provided with an insertion rod 52 matching the insertion hole 43. Figure 7 and Figure 8 As shown, the rubber pressure plate 5 is connected to the ceramic bottle clamp 4 by the groove 51 and the protrusion 42, so that the rubber pressure plate 5 is installed on the ceramic bottle clamp 4 and will not fall off; at the same time, the plug rods 52 on both sides can further improve the stability of the connection by inserting into the plug hole 43 of the ceramic bottle clamp 4, and at the same time, it can prevent the front and rear sides of the rubber pressure plate 5 from sagging due to gravity, and improve the smoothness of the wire fixation device being installed on the ceramic bottle.

[0034] As a further preferred embodiment, such as Figure 7 and Figure 8 As shown, the inner side of the ceramic bottle clamp 4 is provided with an arc-shaped groove 44 that matches the shape of the ceramic bottle, so that it fits the shape of the ceramic bottle better and thus improves the clamping effect; the inner side of the rubber pressure plate 5 is provided with an arc-shaped pressure groove 53 that matches the wire, so that it fits the shape of the wire better and thus improves the clamping effect.

[0035] As a further preferred embodiment, the lower end of the anti-reverse switch 3 is fixed with a bolt 31, and the bottom of the lower cover 1 is provided with a nut 32. The bolt 31 passes through the center hole of the upper cover 2 and the lower cover 1 and is connected to the nut 32 of the lower cover 1. Figure 3 As shown, by rotating the anti-reverse switch 3, the bolt 31 is rotated, which reduces the distance between the bolt 31 and the nut 32, thereby clamping and fixing the lower cover 1 and the upper cover 2. The upper cover 2 cannot rotate on the lower cover 1, which further pre-tightens the lower porcelain bottle clamp 4 and prevents it from loosening.

[0036] As a further preferred embodiment, the top cover 2, the anti-reverse switch 3, and the porcelain bottle gripper 4 are provided with anti-slip grooves 6 to improve the friction of the gripper, thereby making the pre-tightening more effortless and convenient.

[0037] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
