Abstract

The utility model discloses a fixing clamp for parallel service wires, used for transferring power from an outdoor place to a user. The utility model comprises an upper clamping plate, a lower clamping plate, a bottom plate, and a hanging hook, wherein, the upper clamping plate and the lower clamping plate clamp power lines, and the hanging hook is movably connected with the upper part of the bottom plate. The upper clamping plate, the lower clamping plate, and both sides of the bottom plate are provided with connecting holes, and the clamping plates are connected with the bottom plate through screws which pass through the two connecting holes. The fixing clamp has the advantages of reasonable stress, reliable fixation for the power lines, and prevention of damage caused by the pulling of wind force for the power lines. The fixing clamp uses the hanging hook, and thereby, the utility model has the advantages of simple and convenient installation and operation and convenient construction.

Description

Parallel service conductor is clip fixedly

The utility model relates to fixedly clip of a kind of power line.

When outdoor electric power is transported to the user, need use the power line fixture.The normal porcelain knob that adopts Wound-rotor type in the prior art, this porcelain knob be installed on the wall or with the support of wall mounted on.Owing to there is following defective during porcelain knob and wall for fixedlying connected, therefore use: power line stretches tight too tightly or is too loose, cannot stand high wind and blows to shake and pull, and causes dangerous accident; Porcelain knob needs and wall mounted, increases labor strength, causes construction and inconvenient maintenance.

The someone has designed a kind of formula wire clamp of hanging up for this reason, and it is made up of a pair of electric wire clamping plate, base plate, hook.The electric wire clamping plate are connected with two screws in vertical midline with base plate, and hook is connected with the top movable of base plate.Because the right tie point of its electric wire clamping plate is on the vertical center line of clamping plate, and the power line that is fixed is positioned at the both sides of clamping plate, and when screwing screw, the dual-side of electric wire clamping plate has the trend of outside perk, when causing wind-force excessive, electric wire is pulled this wire clamp and loses fixation by wind-force.

In view of above-mentioned, but the purpose of this utility model just provides a kind of convenient construction, prevents that power line is blown by high wind and shakes the service conductor geometrical clamp of pullling and damaging.

For achieving the above object, the utility model is by the following technical solutions:

A kind of parallel service conductor is clip fixedly, a pair of folder is established clamping plate, base plate, the hook of power line about comprising, hook is connected with the base plate top movable, it is characterized in that: connecting hole is established in described both sides of going up lower plate and base plate, and clamping plate are connected by the screw that passes this two connecting hole with base plate.

Ear is extended in described both sides of going up lower plate and base plate, and ear opens connecting hole, and last lower plate is connected by the screw that passes this two connecting hole with base plate.

Described train wheel bridge is made of the stiffening piece on plate body and the plate body, and the both sides of stiffening piece are established connecting hole or extended ear, and ear opens connecting hole.

The utlity model has following advantage: because connecting hole is positioned at the clamping plate both sides, stressed rationally thereby power line grips reliably, can prevent that power line from being pullled and damaging by wind-force; Owing to adopt hook, thereby fitting operation is easy, easy construction; Because hook flexibly connects with base plate, makes connected power line that certain degree of freedom be arranged, thereby has improved anti-pull ability.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is a structural representation of the present utility model.

See also Fig. 1.The utility model is a fixedly clip of parallel service conductor, comprises a pair of clamping plate 4 and 5, metal base plate 2, metal hanger 1 up and down, and train wheel bridge 5 is by metal reinforced 5 on plate body 5 ' and the plate body 5 ' " constitute.Base plate 2, lower plate 4, stiffening piece 5 " both sides extend ear, ear opens connecting hole, two screws 6 of connecting hole link together by passing separately for base plate 2, clamping plate 4 and 5, and the power line 3 that is located between the lower plate 4,5 is fixing.Hook 1 flexibly connects by square hole and the base plate 2 that the one end penetrates base plate 2 tops, and buffering leeway is arranged in the time of can making power line 3 pullled by external force like this.

Base plate 2, clamping plate 4 and 5 also can not established ear and are opened connecting hole in both sides.

Stiffening piece 5 " be to establish for reinforced company's relay, under the enough situation of connection power (as plate body 5 ' thicker or screw 6 thicker etc.), also can be without this stiffening piece, promptly train wheel bridge only is made of plate body.

The utility model is applicable to 4-16mm ²Fixing of power line.

The foregoing description is only enumerated for explanation the utility model, is not to be used to limit the utility model, and any equivalents based on the foregoing description all should be within scope of patent protection of the present utility model.
