Abstract

The utility model discloses a U-shaped non-standard line clamp which comprises a U-shaped sleeve (1), a U-shaped pressing plate (2), a square nut (3) and a step bolt (4). A hole (101) corresponding to the square nut (3) is formed in the U-shaped sleeve (1). The U-shaped pressing plate (2) can only move in the axial direction of the step bolt (4) under the combined effect of the U-shaped sleeve (1), the square nut (3) and the step bolt (4). An abrasion-resisting layer (201) is arranged on the U-shaped pressing plate (2). A screw groove is formed above the step bolt (4) which is connected with the square nut (3) through threads. A fixing mode through one bolt is used, line clamping efficiency is improved, and the reliability of the line clamp is improved, and the service life of the line clamp is prolonged.

Description

A kind of U-shaped nonstandard line card

Technical field

The utility model relates to a kind of line card, is specifically related to a kind of U-shaped nonstandard line card.

Background technique

Line card is mechanical field application fastening piece very widely, the existing a kind of line card generally adopting is made up of a U-shaped reinforcing bar, pressing plate and two pieces of nuts, when use, line is put into U-shaped reinforcing bar and overlapped again top board, then the nut of screwing on respectively at two of U-shaped reinforcing bar, thus reach the object of fixed cable; But it need to be screwed at every turn, two pieces of nuts are wasted time and energy, and easily because uneven working life that affects line card firmly when nutting.

Model utility content

The utility model, for prior art deficiency, provides a kind of U-shaped nonstandard line card simple in structure, easy to use, can complete comparatively easily the fixing work of cable, increases work efficiency; Because it adopts one piece of fixing mode of bolt to avoid because unbalance stress affects line card working life.

For solving the problems of the technologies described above, the utility model provides a kind of U-shaped nonstandard line card, comprises U-shaped cover (1), U-shaped pressing plate (2), square nut (3) and half-round head square neck bolt (4); On described U-shaped cover (1), offer the hole (101) corresponding with square nut (3); Described U-shaped pressing plate (2) is realized it and can only on the axial direction of half-round head square neck bolt (4), be moved under U-shaped cover (1), square nut (3) and half-round head square neck bolt (4) acting in conjunction; Described square nut (3) is threaded connection with half-round head square neck bolt (4).

Wherein, the inwall width of described U-shaped pressing plate (2) is consistent with the width of square nut (3).

Wherein, described U-shaped pressing plate (2) is provided with wearing layer (201).

Wherein, described half-round head square neck bolt (4) top offers flight.

Wherein, U-shaped nonstandard line card surface adopts chromium plating processing.

Compared with prior art, one piece of fixing mode of bolt of the utility model employing improves the efficiency of clamp, has increased reliability and the working life of wire clamp.

Brief description of the drawings

Fig. 2 is the erection drawing of the U-shaped nonstandard line card of the utility model.

Fig. 3 is the partial sectional view of the U-shaped nonstandard line card plan view of the utility model.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.

The structure of the U-shaped nonstandard line card of the utility model as Figure 1-3, comprises U-shaped cover 1, U-shaped pressing plate 2, square nut 3 and half-round head square neck bolt 4; On described U-shaped cover 1, offer the hole corresponding with square nut 3 101; Described U-shaped pressing plate 2 is realized it and can only on the axial direction of half-round head square neck bolt 4, be moved under U-shaped cover 1, square nut 3 and half-round head square neck bolt 4 actings in conjunction; Described square nut 3 is threaded connection with half-round head square neck bolt 4.

In the present embodiment, the inwall width of described U-shaped pressing plate 2 is consistent with the width of square nut 3, thereby limits the movement of U-shaped pressing plate 2 on nut 2 width directions and the rotation taking nut as axle center.

In the present embodiment, described U-shaped pressing plate 2 is provided with wearing layer 201, while its role is to clamp cable, between half-round head square neck bolt 4 and U-shaped pressing plate 2, there is larger pressure, therefore in the time that half-round head square neck bolt 4 is screwed into and U-shaped pressing plate 2 there is very large frictional force, this wearing layer can improve the scurf resistance of U-shaped pressing plate 2, improves its working life.

In the present embodiment, described half-round head square neck bolt (4) top offers flight, therefore in the time being screwed into half-round head square neck bolt 4, not only can adopt spanner but also can adopt screw-driver to tighten, and has strengthened operability.

In the present embodiment, U-shaped nonstandard line card surface adopts chromium plating processing, has greatly strengthened hardness and the wear resistance of line card, the working life of having improved product.

When use, the cable first needs being clamped is put into U-shaped cover 1, then puts into U-shaped pressing plate 2, then square nut 3 is passed in the hole 101 of correspondence with it from U-shaped cover 1, finally half-round head square neck bolt 4 is screwed in square nut 3.Along with being constantly screwed into of half-round head square neck bolt 4, because square-head nut 4 is relatively fixing in the U-shaped position putting, therefore U-shaped clamping plate constantly step up the cable in U-shaped cover 1 under the effect of half-round head square neck bolt 4.

These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
