Abstract

The utility model discloses an automatic cable clamp which is used for connecting the end with a fixed equipment in wire constructing operation. A clamping mechanism is composed of a casing tube whose inner is of a conical cavity, and clamping blocks which are arranged in the conical cavity and are adaptively matched with the conical cavity. The clamping blocks are at least two and are corresponding with each other, and the size and the shape are the same. The end surface of the extending end of the casing tube to the surface of the inner cavity is an arc smooth surface. The utility model has the advantages of simple structure, automatic clamping wire, convenient operation, quick construction, labour saving and time saving.

Description

Automatic cable clamp

The utility model belongs to and sets up the clamping device that lead is used, and particularly a kind of lead terminal is connected the automatic strain clamp of usefulness with permanent plant.

Current, when the wire erection operation, its terminal all is to adopt bolt type strain clamp or crimp type wire clamp to be connected and fixed.The shortcoming of this wire clamp is construction and maintenance trouble, operates inconvenience, time-consuming.Disclosing the strain insulator upside-down mounting wire clamp of CN2112899U on China's utility model patent communique, is the improvement to above-mentioned bolt type strain clamp, brings certain convenience to construction, but still in various degree exist above-mentioned shortcoming.

The purpose of this utility model provides a kind of tension by lead, makes between the wire clamp member automatic strain clamp that slide relative takes place and lead is clamped.It has simple in structure, and is easy to operate, fast and the advantage of saving of work and time, has overcome the shortcoming of prior art existence.

The technical solution of the utility model is formed by clamp system with its hanging mechanisms that can be fastenedly connected.Clamp system is to be the sleeve pipe of cone-shaped cavity and to be contained in its inside fixture block that cooperates that adapts with it and to constitute by inside.Fixture block is corresponding two of being provided with at least, and size is identical with shape, and its section is an arcwall face, and side-looking face is a taper surface.

Sleeve pipe is a cone, also can be Cylinder or cuboid.Be provided with screw thread with the link of hanging mechanisms, the end face of its other end to inner cavity surface is an arcwall face.

One end of hanging mechanisms is the swivel nuts with internal thread, and the other end is the link plate that has mount hole, and is corresponding two.

In swivel nut, also be provided with back-up ring, in order to place restrictions on the position of fixture block.

The utility model compared with prior art has simple in structure, and lead can be clamped automatically, and is easy to operate, constructs fast and the advantage of saving of work and time.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1: topology view of the present utility model.

Fig. 2: 2 A-A cutaway view Amplified image among Fig. 1.

(accompanying drawing) makes following detailed description to the utility model in conjunction with the embodiments:

As described in Figure 1, the utility model is made up of clamp system and hanging mechanisms.Clamp system is threaded cone sleeve pipe 1 to be set and to be contained in two corresponding fixture blocks 2 that adapt to cooperation in its inner cone chamber 8 with it by an end to constitute.The other end end face of sleeve pipe to inner cavity surface is the sliding arcwall face in garden.The section of fixture block 2 is arcwall face (Fig. 2).One end of hanging mechanisms is thread bushs 4, and the other end is the link plate with mount hole 65 that becomes one with it.On the wall of thread bush 4, also be respectively arranged with trip bolt 3 and back-up ring 7 with its inside.

Operation principle of the present utility model is: when air line working, fixture block 2 is installed between cone sleeve pipe 1 and the lead 9, because under the deadweight of lead 9 and the effect of the frictional force between tension and lead 9 and the fixture block 2, fixture block 2 is slided to draw direction (promptly boring 8 tips, chamber) with lead 9, be subjected to displacement with respect to cone sleeve pipe 1 and produce clamping force, with its automatic clamping lead 9.

Claims

1, a kind of automatic strain clamp, by clamp system with can tighten up the hanging mechanisms that are connected with it and form, it is characterized in that clamp system is is that the sleeve pipe and being arranged in the chamber of cone-shaped cavity constitutes with its fixture block that cooperates that adapts by inside, fixture block is at least corresponding two, and its size, shape are identical.

2, automatic strain clamp according to claim 1 is characterized in that the end face of sleeve pipe external part is the garden arcuation to boring the chamber inner face.

3, automatic strain clamp according to claim 1 is characterized in that hanging mechanisms one end is the thread bush with internal thread, and its other end is the link plate that has mount hole.

4, claim 1 or 3 described automatic strain clamps is characterized in that also being provided with in the described thread bush spacing back-up ring.
