Description

A kind of strain clamp

Technical field

The utility model relates to line of power equipment technical field, specially a kind of strain clamp.

Background technique

Strain clamp refers to for fixing conducting wire, to bear wire tension, and conducting wire is hung to strain insulator-string group or shaft tower Fitting.Strain clamp presses the difference of structure and mounting condition, can generally be divided into two classes.The first kind: strain clamp will be born Whole pulling force of conducting wire or lightning conducter, grip of clamp, which is not less than, is mounted the 90% of conducting wire or the specified stretching resistance of lightning conducter, but not As electric conductor.This kind of wire clamp can also remove after conducting wire installation, separately use.Such wire clamp have bolt-type strain clamp and Wedge shape strain clamp etc..Second class: strain clamp is in addition to the whole pulling force for bearing conducting wire or lightning conducter, and as electric conductor.Cause This this kind of wire clamp cannot go disassembly after installation again, also known as dead wire folder.Due to being electric conductor, the installation of wire clamp is necessary It is conscientiously carried out in accordance with the regulation in relation to installing operating instruction.

Wire rod in winter with summer when, be easy expanded with heat and contract with cold by external environment impression, traditional strain clamp lacks reply Measure, there is wire rod in winter because the reason of shrinkage causes to snap, since thermal expansion leads to wire rod height not when summer Up to standard to cause Danger Electric shock risk, the design can be protected for the present flexible replacement tension spring of different spans, unlike material Wire rod will not be damaged, while can guarantee that it has certain tensile force, guarantee the height of wire rod, avoid electric shock danger Danger.

Utility model content

(1) the technical issues of solving

In view of the deficiencies of the prior art, the utility model provides a kind of strain clamp, solves traditional strain clamp and lacks Measure to Different climate reply, in winter wire rod because the reason of shrinkage cause to snap, since thermal expansion causes when summer Wire rod height the problem of causing Danger Electric shock risk not up to standard.

(2) technical solution

In order to achieve the above object, the utility model is achieved by the following technical programs: a kind of strain clamp, including U Type bolt, U-bolt middle upper portion position are provided with fixed plate, and side medium position is fixedly connected below the fixed plate There is connecting rod, the connecting rod bottom position is fixedly connected with tension spring, and the tension spring bottom position is fixedly connected with pull rod, described U-bolt is located at pull rod the same horizontal position and is provided with limit plate, and the pull rod is provided with through limit plate side bottom position Fixing lock.

Preferably, the U-bolt outer wall and it is located at limit plate and is provided with location nut in two sides up and down, the limit plate is left Right both ends are fixedly connected by location nut with U-bolt, and the location nut inner wall position is threadedly coupled with U-bolt.

Preferably, the tension spring external position is provided with rubber seal cover.

Preferably, U-bolt bottom outer wall position is threaded with fixture nut, between the fixture nut (10) It is provided with gasket.

Preferably, there are four the location nut and fixture nut are respectively provided with, there are two the gasket settings.

Preferably, the fixing lock lower middle position is provided with conducting wire.

(3) beneficial effect

The utility model provides a kind of strain clamp.Have it is following the utility model has the advantages that

(1), the strain clamp is provided with fixed plate, a middle side part below fixed plate by U-bolt middle upper portion position Position is fixedly connected with connecting rod, and connecting rod bottom position is fixedly connected with tension spring, and tension spring bottom position is fixedly connected with pull rod, Tension spring can control the tension of wire rod, reach the weather conditions for making wire rod flexible adaptation different, can voluntarily control it Length and tension avoid snapping because tension is much, and tension is too small to lead to wire rod sagging the problem of leading to electric shock.

(2), the strain clamp is located at pull rod the same horizontal position by U-bolt and is provided with limit plate, and limit plate can Play the role of protecting tension spring, preventing it, excessive tensile leads to its damage under the effect of external force, has reached protection tension spring, extends The purpose of its service life.

Fig. 2 the utility model stretching structure enlarged drawing.

In figure: 1U type bolt, 2 fixed plates, 3 connecting rods, 4 tension springs, 5 pull rods, 6 limit plates, 7 fixing locks, 8 location nuts, 9 Rubber seal cover, 10 fixture nuts, 11 gaskets, 12 conducting wires.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1~2 are please referred to, the utility model provides a kind of technical solution: a kind of strain clamp, including U type bolt 1, U 1 middle upper portion position of type bolt is provided with fixed plate 2, and 2 lower section side medium position of fixed plate is fixedly connected with connecting rod 3, even 3 bottom position of extension bar is fixedly connected with tension spring 4, and 4 bottom position of tension spring is fixedly connected with pull rod 5, and it is same that U-bolt 1 is located at pull rod 5 One horizontal position is provided with limit plate 6, and pull rod 5 is provided with fixing lock 7 through 6 side bottom position of limit plate, outside U-bolt 1 Wall and it is located at about 6 two sides of limit plate and is provided with location nut 8,6 left and right ends of limit plate passes through location nut 8 and U-bolt 1 It is fixedly connected, 8 inner wall position of location nut is threadedly coupled with U-bolt 1, and 4 external position of tension spring is provided with rubber seal cover 9, U 1 bottom outer wall position of type bolt is threaded with fixture nut 10, and gasket 11, location nut 8 are provided between fixture nut 10 There are four being respectively provided with fixture nut 10, there are two the settings of gasket 11, and 7 lower middle position of fixing lock is provided with conducting wire 12.It reaches Lack the measure to Different climate reply to traditional strain clamp is solved, wire rod causes to stretch tight because of the reason of shrinkage in winter It is disconnected, since thermal expansion leads to wire rod height the problem of causing Danger Electric shock risk not up to standard when summer.

In use, 1 or so bottom bolts position of U-bolt is fixed on the mounting bracket by fixture nut 10, top The effect that fixture nut 10 positions, the fixture nut 10 of lower section play the purpose of locking, and gasket 11 can protect fixture nut 10 It is not scratched, conducting wire 12 inside pull rod 5 by fixing lock 7 via being pierced by, and fixing lock 7 plays the role of locking, and tension spring 4 is not according to Same span and wire rod is selected in advance sets, and tension spring 4 stretches under the action of present self weight and reserved pulling force, when summer Wire rod is waited due to the hotter scene elongation of weather, reserved pulling force becomes smaller at this time, and tension spring 4 is shunk, and conducting wire 12 is shunk, when winter It waits wire rod to shorten, pulling force becomes larger, and tension spring 4 is elongated, wire rod elongation, and location nut 8 can play protection tension spring 4 due to external force The purpose that excessive tensile causes it to damage, fixture nut 10 can play fixed effect, reach the traditional strain clamp of solution Lack the measure to Different climate reply, in winter wire rod because the reason of shrinkage cause to snap, due to thermal expansion when summer Lead to wire rod height the problem of causing Danger Electric shock risk not up to standard.
