Abstract

The utility model relates to a tensioning clamp for installing cables, which is used for installing the cables for industries such as electric power, telecommunication, etc., and comprises a clamp main body, a pressing block, a connecting plate and a draw rod, wherein the connecting plate forms a triangular; three corners are respectively hinged with the clamp main body, the pressing block and the draw rod through hinging shafts; springs are respectively arranged between the connecting plate, the clamp main body and the pressing block so that the pressing block automatically presses downward under the natural state; the draw rod passes through an oblong hole of the clamp main body; the end part of the draw rod is made into an annular shape which is used for tying a draw rope; the bottom face of the pressing block is matched with the face of the clamp main body into a rope clamping port; the rope can be put in the face of the clamp main body; the bottom face of the pressing block is carved with saw teeth for preventing a clamping rope from sliding; the hinging shaft of the pressing block is hinged with a cable baffle plate; the baffle plate can rotate along the hinging shaft, baffle the outer margin of the rope clamping port and lead the rope clamping port not to slide outward. The utility model has the characteristics of reasonable integral structure, convenient use, etc. The utility model does not need large force for clamping cables tightly. The clamping port does not slide. The utility model can be used for the cables which are coated with rubber as well as the bare conducting wires. The utility model can tightly clamp the cables with large range of the diameter.

Description

The cable stretching device is installed

Technical field

The utility model relates to the mounting technique field of cable or wire, especially relates to the erecting tools technical field that is used to strain cable or wire.

Background technology

The transmission of electricity of electric power system, telecommunication, etc. industry all need cable laying or lead, cable or wire must be strained during installation, be a kind of fixing-line device as what the cable tensioning tool was installed at present, it can realize straining cable preferably, but because global design, especially the structure of bayonet socket is not very desirable, and it is very big to exert oneself when often blocking, and also the phenomenon that backguy is skidded can occur sometimes.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned defective, improves on the basis of existing fixing-line device, provides a kind of handsome in appearance, easy to use, need not change very energetically during chucking, and bayonet socket is non-slip, and installation cable stretching device applied widely.

For achieving the above object, the technical solution of the utility model is such: a kind of installation cable stretching device comprises jig main body, briquetting, connecting plate and pull bar; Wherein connecting plate is triangular in shape, and three corner location are hinged with jig main body, briquetting and pull bar respectively by hinge; Between connecting plate and jig main body and briquetting, be respectively equipped with spring, so that press down automatically at the nature lower lock block; Pull bar passes the oblong aperture of jig main body, and the end is done circlewise, the cross-under puller system; The bottom surface of the briquetting formation wire blocking port that matches with the line face of putting of jig main body, said briquetting bottom surface is the inner concave of tile, on be carved with sawtooth, skid with the anti-sticking line; Also be hinged with a cable baffle plate on the hinge of briquetting, this baffle plate can rotate along hinge, and the wire blocking port outer rim is blocked, and does not make outer sliding.

Owing to adopted technique scheme, a kind of installation cable stretching device of the present utility model has reasonable integral structure, and characteristics easy to use need not changed very energetically during chucking, and bayonet socket is non-slip, both can be used for cabtyre cable, also can be used for plain conductor; Owing to adopt three hinges, make bayonet socket can Zhang Degeng big, thereby the line footpath all can clamp in a big way, applied widely.

Among the figure: 1, pull bar, 2, hinge, 3, connecting plate, 4, the cable baffle plate, 5, hinge, 6, hinge, 7, jig main body, 8, briquetting, 9, put the line face, 10, wire blocking port, 11, the briquetting bottom surface, 12, the wedge mouth.

Embodiment

By Fig. 1-shown in Figure 4, a kind of installation cable stretching device of the present utility model comprises jig main body 7, briquetting 8, connecting plate 3 and pull bar 1; Wherein connecting plate is triangular in shape, and three corner location are hinged with jig main body, briquetting and pull bar respectively by

hinge

5,6,2; Between connecting plate and jig main body and briquetting, be respectively equipped with spring, so that press down automatically at the nature lower lock block; Pull bar passes the oblong aperture of jig main body, and the end is done circlewise, in order to connect puller system; Match with the line face 9 of putting of jig main body and form wire blocking port 10 in briquetting bottom surface 11, said briquetting bottom surface 11 is the inner concave of tile, on be carved with sawtooth, skid with the anti-sticking line; Also be hinged with a cable baffle plate 4 on the hinge 6 of briquetting, this baffle plate can rotate along hinge, and wire blocking port 10 outer rims are blocked, and does not make outer sliding;

After making completion, cable makes the side of deviating from from wire blocking port 10, makes a wedge mouth 12 on briquetting bottom surface 11.

Claims

1, a kind of installation cable stretching device, comprise jig main body (7), briquetting (8), connecting plate (3) and pull bar (1), it is characterized in that: said connecting plate is triangular in shape, and three corner location are hinged with jig main body, briquetting and pull bar respectively by hinge (5,6,2); Between connecting plate and jig main body and briquetting, be respectively equipped with spring; Pull bar passes the oblong aperture of jig main body, and the end is done circlewise; Match with the line face of putting (9) of jig main body and form wire blocking port (10) in briquetting bottom surface (11), said briquetting bottom surface (11) is the inner concave of tile, on be carved with sawtooth; On the hinge (6) of briquetting, also be hinged with a cable baffle plate (4).
