Description

Technical Field

[0001] This utility model relates to the field of insulator clamps, and in particular, to a clamping structure for clamping and insulators. Background Technology

[0002] Insulator clamps are used for insulator maintenance. When several insulators in an insulator group are damaged or broken, two clamps are placed at both ends of the damaged insulators. The clamps at both ends are tightened using a screw assembly to facilitate the replacement of the damaged or broken insulators. Most existing insulator structures use connected steel caps and magnetic components. The steel cap of the insulator has a protrusion, and the connection between the steel cap and the magnetic component has an annular abutment. The abutment is connected to the protrusion and gradually decreases in size from top to bottom. The connection between the abutment and the magnetic component has an annular accommodating gap.

[0003] Traditional clamps with claws at both ends (one end fits onto the protrusion correctly, and the other end fits onto the protrusion incorrectly) often lock onto the protrusions on the steel cap, such as... Figure 3 The upper end is the positive sleeve, and the lower end is the negative sleeve, which achieves limiting. However, firstly, because most steel cap bodies are designed with components increasing in size from top to bottom, after the screw assembly is tightened, one end of the positive sleeve is not easy to slip off due to the shape of the steel cap body, while the other end of the negative sleeve is easy to slip off, resulting in poor limiting and fixing effect; secondly, insulator manufacturers are different, and they all use the same traditional double clamping. The positive sleeve clamps from the outside to the inside, so there is enough space, while the negative sleeve opens from the inside to the outside, so the negative sleeve may not have enough space; thirdly, the claw position of the traditional hinge has a large range of motion, and the claw needs to be manually moved to make the claw fall into the correct position, close the clamp, and achieve fixing. Therefore, it is relatively laborious and poses a safety hazard when working at height. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology, at least to a certain extent, the technical problems in the related technology, and to provide solutions to the problems of serious safety hazards, poor limiting effect, and poor universal adaptability of existing clamps.

[0005] A clamping structure for a clamp and an insulator includes a first clamp, a second clamp, and an insulator assembly. The insulator assembly includes several insulators that are interlocked. Each insulator includes a connected steel cap and a magnetic component. The steel cap of the insulator has a protrusion. The two ends of the first clamp and the second clamp are connected by a lead screw assembly. The connection between the steel cap and the magnetic component has an annular abutment portion, which is connected to the protrusion. The abutment portion gradually decreases in size from top to bottom. The connection between the abutment portion and the magnetic component has an annular receiving gap. The first clamp includes a first clip. The first clamp includes a first clamp body and a first clamp cover connected to the first clamp body, characterized in that: both the first clamp body and the first clamp cover are provided with a plurality of first clamp claws, and the first clamp claws are provided with an open groove adapted to one side of the protrusion to limit and fix one end of the insulator assembly; the second clamp includes a second clamp body and a second clamp cover connected to the second clamp body, both the second clamp body and the second clamp cover are provided with a plurality of second clamp claws, the second clamp claws are provided with a first clamping part adapted to the protrusion, and the first clamping part is provided with a limiting groove adapted to the protrusion to limit and fix the other end of the insulator assembly.

[0006] Furthermore, the first engaging portion includes a hook portion, which extends into the receiving gap and abuts against the abutting portion.

[0007] Furthermore, after the first card body and the first card cover are closed, a square receiving groove is formed. Both the first card body and the first card cover are hinged with two first card claws, and the four card claws are respectively located at the four corners of the receiving groove.

[0008] Furthermore, after the second card body and the second card cover are closed, a square receiving groove is formed. Both the second card body and the second card cover are hinged with two second card claws, and the four card claws are respectively located at the four corners of the receiving groove.

[0009] Furthermore, a notch is provided in the lower middle part of the first and second jaws.

[0010] The main technical effects of this utility model are reflected in the following aspects: 1: One end of the insulator assembly is clamped by a first clamp, which clamps the gradually increasing steel cap from the outside to the inside through the open groove, and is limited by the protruding side. The other end is clamped by a second clamp, which limits the protruding periphery through the limiting groove. Compared with the traditional two sets of clamps, it prevents the phenomenon of insufficient position at the end clamped from the inside to the outside, so as to adapt to insulators produced by various manufacturers and have wider versatility.

[0011] 2: The first engaging part includes a hook, which extends into the receiving gap and abuts against the abutting part. Through the above design, because the abutting part is an inverted frustum design, on the one hand, the limiting groove clamps the protruding periphery; on the other hand, the hook extends into the receiving gap and abuts against the top surface of the abutting part, achieving double limiting to prevent slippage and making the stability after limiting stronger, ensuring effective limiting.

[0012] 3: The two claws on the card body are limited on both sides by the square receiving groove wall, and the two claws are also mutually limited, which restricts the range of motion of the two claws on the first and second card bodies. The two claws on the card cover are limited on both sides by the square receiving groove wall, and the two claws are also mutually limited, which restricts the range of motion of the two claws on the first and second card covers. When working at height, it is convenient and efficient to make each group of four claws fall into place. Attached Figure Description

[0027] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. This application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12The diagram shows a clamping structure for an insulator, comprising a first clamp 1, a second clamp 2, and an insulator assembly 3. The insulator assembly 3 includes several insulators 3 that are interlocked. Each insulator 3 includes a connected steel cap 31 and a magnetic component 32. The steel cap 31 of the insulator 3 has a protrusion 33, and an annular abutment 34 is provided at the connection point between the steel cap 31 and the magnetic component 32. The abutment 34 gradually decreases in size from top to bottom. The connection point between the abutment 34 and the magnetic component 32 has an annular receiving gap 35, which is a conventional insulator 3 structure. The two ends of the first clamp 1 and the second clamp 2 are respectively connected by a lead screw assembly 4, which is used for... The first clamp 1 and the second clamp 2 are tightened. The first clamp 1 includes a first clamp body and a first clamp cover connected to the first clamp body. The first clamp body and the first clamp cover adopt an existing connection structure. Both the first clamp body and the first clamp cover are provided with a plurality of first clamp claws 101. The first clamp claws 101 are provided with an open groove 102 adapted to one side of the protrusion 33 to limit and fix one end of the insulator assembly. The second clamp 2 includes a second clamp body 21 and a second clamp cover 22 connected to the second clamp body 21. The second clamp body 21 and the second clamp cover 22 adopt an existing connection structure. Preferably, both the second clamp body 21 and the second clamp cover 22 are provided with a plurality of second clamp claws 23. The second clamp claws 23 are provided with a first locking part 24 adapted to the protrusion 33. The first locking part 24 is provided with a limiting groove 103 adapted to the protrusion 33. After the second clamp body 21 and the second clamp cover 22 are closed, the protrusion 33 is limited in the limiting groove 103 to limit and fix the other end of the insulator assembly.

[0030] One end of the insulator assembly is secured by a first clamp, which clamps the gradually enlarging steel cap from the outside in through an open groove and is limited by one side of the protrusion 33. The other end is secured by a second clamp, which limits the periphery of the protrusion 33 through a limiting groove 103. Compared with the traditional two sets of clamps, this design prevents the phenomenon of insufficient position at one end when clamped from the inside out, thus adapting to insulators produced by various manufacturers and having wider versatility.

[0031] The first engaging portion 24 includes a hook portion 104, which extends into the receiving gap and abuts against the abutting portion. Through this design, because the abutting portion is an inverted frustum, on the one hand, the limiting groove 103 clamps and limits the periphery of the protrusion 33; on the other hand, the hook portion 104 extends into the receiving gap and abuts against the top surface of the abutting portion, achieving double limiting to prevent slippage and making the stability after limiting stronger, ensuring effective limiting.

[0032] When the first card body and the first card cover are closed, they form a square receiving groove. Both the first card body and the first card cover are hinged with two first card claws, and the four card claws are located at the four corners of the receiving groove.

[0033] When the second card body 21 and the second card cover 22 are closed, a square receiving groove 5 is formed. The second card body 21 and the second card cover 22 are each hinged with two second card claws 23, and the four card claws are respectively located at the four corners of the receiving groove 5.

[0034] Through the above design, the two claws on the card body are respectively limited by the square receiving groove 5 on both sides, and the two claws are also mutually limited, which restricts the range of motion of the two claws on the first and second card bodies. The two claws on the card cover are respectively limited by the square receiving groove wall on both sides, and the two claws are also mutually limited, which restricts the range of motion of the two claws on the first and second card covers. During high-altitude operations, it is convenient and efficient to make each group of four claws 23 fall into place.

[0035] The first and second jaws have a notch at their lower center. The notch 6 design makes it easier for the four jaws of each jaw to automatically center after the first and second jaws are tightened.

[0036] Of course, after assembly, once the second clamp 2 is engaged and closed, the hook will not touch the magnetic component 32 due to the limiting position between the protrusion 33 and the limiting groove 103, thus preventing damage to the magnetic component.

[0037] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
