Description

A kind of lever wire clamp suitable for wide cut across footpath scope

Technical field

Electric armour clamp technical field is the utility model is related to, more particularly, to a kind of lever suitable for wide cut across footpath scope Wire clamp.

Background technology

Switching and fixing device of the wire clamp as a kind of common electric power facility power transmission line, are widely used in various transmissions of electricity Power supply facilities.At present, universal most of wire clamps all exist：Installation and the operation safeguarded are relatively complicated, its clamp when wire clamp uses Narrow scope, it is impossible in order to ensure the stability of facility and subtract when being common to power transmission line line style similar in model, and installing The resistance of small wire clamp so that mounting torque is larger, virtually adds the labor intensity and workload of operating personnel, installation and dimension The cost of shield is larger.

Utility model content

In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide a kind of safe to use and energy It simultaneously can effectively lower the lever wire clamp of mounting torque and resistance suitable for wide cut across footpath scope.

In order to achieve the above object, the utility model is achieved through the following technical solutions：One kind is suitable for wide cut across footpath model The lever wire clamp enclosed includes matrix and clamp arm, and wherein clamp arm is riveted on the upper and lower of matrix respectively with the midpoint of matrix is in a center of symmetry It is then corresponding respectively with clamp mouth on matrix and mounting hole that both sides, the clamp mouth being located in clamp arm and end open up connecting hole, Bolt is installed with mounting hole and is anchored, the silk mouth end of bolt is then connected through connecting hole and with moment of torsion nut.It is through clamp arm and base Also be coated with compression spring on the body of rod of bolt between body, the both ends of spring respectively with clamp arm and matrix apical grafting.

The technical principle of this programme is：Using lever principle carry out structure design, using the articulated section of clamp arm and matrix as Fulcrum, the connecting portion of another movable end of clamp arm and the distance of fulcrum are then several times as much as distance of its clamp mouth apart from fulcrum, therefore pacify Only less lower pressure need to be used to produce larger thrust to the power transmission line in clamp mouth during dress, so as to reduce wire clamp Resistance, advantageously reduces power Transmission loss, ejects clamp arm in installation and while safeguarding in the spring of bolt upper sleeve through in addition so that It is more time saving and energy saving when installing and safeguarding.

Compared with prior art, the beneficial effects of the utility model are：The utility model is designed reasonably, applicable electric wire Model is in extensive range, and the wire range that can be clamped is big, while utilizes lever principle, increases the torque arm length of stress, and be aided with Spring supporting clamp arm so that it is more time saving and energy saving when installing and safeguarding, and clamp arm and base mate more can effectively increase clamping Power, so as to reduce the resistance of wire clamp, reduces the transport loss of electric power energy.

Other optimizations of the technical program or preferred embodiment further include：

1st, the clamp mouth in the middle part of the clamp arm and on matrix is arc-shaped, its radius size is not less than 6.5mm.

2nd, the bolt is with the midpoint of matrix arrangement in a center of symmetry.

Brief description of the drawings

The utility model will illustrate by example and with reference to the appended drawing, wherein：

Fig. 1 is the utility model structure diagram；

Fig. 2 is the utility model side structure schematic diagram.

Marked in figure：Matrix 1, clamp arm 2, clamp mouth 3, clamp mouth 4, connecting hole 5, mounting hole 6, bolt 7, moment of torsion nut 8, Compress spring 9.

Embodiment

Below in conjunction with the accompanying drawings, the utility model is described in detail.

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining The utility model, is not used to limit the utility model.

As shown in Figures 1 and 2,：A kind of lever wire clamp suitable for wide cut across footpath scope includes matrix 1 and clamp arm 2, its Middle clamp arm 2 with the midpoint of matrix 1 both sides in a center of symmetry up and down for being riveted on matrix 1 respectively, clamp mouth 3 in clamp arm 2 with And the connecting hole 5 that end opens up is then corresponding respectively with the clamp mouth 4 on matrix 1 and mounting hole 6, and spiral shell is installed with mounting hole 6 Bolt 7 simultaneously anchors, and the silk mouth end of bolt 7 is then connected through connecting hole 5 and with moment of torsion nut 8.It is through between matrix 1 and clamp arm 2 Also be coated with compression spring 9 on the body of rod of bolt 7, the both ends of spring respectively with 2 phase apical grafting of matrix 1 and clamp arm.First twisted during use Move and unclamp the connection of torque nut 8 and bolt 7, after torque nut 8 leaves bolt 7, since compression spring 9 is in compression shape State, compression spring 9 resiliently returns to natural length after torque nut 8 leaves, at this time can be by power transmission line with this open-top clamp arm 2 Transverse direction is put into the clamp mouth 4 on matrix 1, then the connecting hole 5 of clamp arm 2 is sleeved on to the silk mouth end pushing of bolt 7, in lever principle The lower mounting torque of effect is smaller, can be easily so that clamp mouth 3 and clamp mouth 4, which are harmonious, compresses power transmission line, its thrust can be with applying The torque increase that adds and increase, to achieve the purpose that reduction wire clamp resistance, finally the torque nut 8 in the silk mouth end cap of bolt 7 And tighten, so as to complete the installation of wire clamp.

In order to make the present apparatus be suitable for the power transmission line compared with Long span, the radius of the clamp mouth 3 and clamp mouth 4 is not less than 6.5mm, suitable for the requirement of the power transmission line of larger line footpath, meets the trend demand of power Transmission；In addition to improve line Total tune, stability and stress equalization after folder installation, the bolt 7 is with the midpoint of matrix arrangement in a center of symmetry.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
