Abstract

The utility model discloses a cable antitheft fixture, which is characterized in that the fixture comprises a guide inner tube, a guide outer tube arranged out of the guide inner tube, and a guide tube sleeved at the rear end of the guide outer tube, the guide tube further includes a guide portion and a connecting portion, and the cross-section diameter of the guide portion is greater than the guide outer tube. The cable antitheft fixture reduces risks of stolen cable well, brings significant economic effects for the country, and brings good social order for the rapid development of urban construction.

Description

Cable anti-theft clamp

Technical field

The utility model relates to the anti-theft device in the fields such as street lamp control cables, telecommunications control cables, especially a kind of cable anti-theft clamp.

Background technology

Current, in the cable application field, widely used is screw link mode, if installer's screw is twisted not tightly, the offender is the theft of the easy enforcement of energy just, and the national loss that has produced is inestimable thus.In prior art, not yet find effectively to prevent the device that cable is stolen.In all kinds of engineerings, be laid in outdoor cable easily stolen, after the cable two ends are cut off, just can easily from an extraction, the property of the people and country be sustained losses severely.

Chinese utility model patent application ZL200520040831.8 has also disclosed a kind of cable anti-theft clamp, the operation principle of this fixture is: before upper loose-leaf and lower loose-leaf close up, upper loose-leaf and lower loose-leaf are filled the span of a man's arms cable between upper containing cavity and lower containing cavity, upper loose-leaf and lower loose-leaf are exerted pressure to cable respectively, make cable be pressed between containing cavity and lower containing cavity, ratchet shaft is with after nut is connected, upper loose-leaf and lower loose-leaf are realized fixing, continuing rotary actuation ratchet axial nut direction advances, pressure between loose-leaf and lower loose-leaf is increased, ratchet is snapping under the effect of spring between the double wedge of ratchet, make the ratchet can't counter-rotating, therefore, ratchet shaft can't reverse rotation to withdraw from from nut, like this, cable has just been realized fixing with fixture of the present utility model, fixture is fixedly connected with immovable job facilities, cable can be fixed.

But this structure is relatively complicated, and manufacturing cost is higher, and is not suitable for a large amount of cable theft-prevention fields of using of large tracts of land.

Summary of the invention

, in order to solve the field operation workman after the operation that conscientiously fulfils assignment, still there is the stolen hidden danger of cable.Simultaneously, simple for reaching execute-in-place, the lasting purpose reliably of anti-theft feature, the utility model provides a kind of cable anti-theft clamp, can bring obvious economic effect for country, is the fast development of urban construction, brings good civil order.

In order to realize the foregoing invention purpose, the utility model discloses cable anti-theft clamp, it is characterized in that, described fixture further comprises:

One guiding inner tube, be set in the outer guiding outer tube of described guiding inner tube, and a guide pipe that is set in described guiding outer tube back-end, described guide pipe further comprises a guide part and a junction, and the Zhou Jing of described guide part is greater than described guiding outer tube.

Reasonablely be, cable anti-theft clamp of the present utility model, described guiding outer tube further comprises:

be arranged on a guide part and an extension of described guiding outer tube front end, described guide part is hollow tubular, with the concentricity axle of described guiding inner tube, and be set in the outside of described guiding inner tube, described extending part is in the rear end of described guide part and be gradually open shape, tapered bottom end flange processing at described extension, the connecting portion vertical center axis of described guide pipe also is fixed on the periphery wall of the described guide part of described guide pipe, by described extension, form a cone space between described guide part and described guiding inner tube, also be provided with some lock balls and a flexible member in the zone of described cone space, wherein said lock ball is embedded in some shrinkage pools that symmetry is offered on the caliber of described guiding inner tube, one end of described lock ball is near the inwall of described extension, the other end is fixed described flexible member, the other end of described flexible member is fixed on described guide part.

Reasonable is that cable anti-theft clamp of the present utility model, the connecting portion of described guide pipe are steel plates.

Reasonablely be, cable anti-theft clamp of the present utility model, symmetry is offered 4 shrinkage pools on the caliber of described guiding inner tube, and correspondence arranges 4 lock balls.

Reasonablely be, cable anti-theft clamp of the present utility model, described flexible member further comprises spring.

The utility model uses in often stolen highway section and uses, and can avoid occurring the stolen situation of cable again.Thus, can be country and save a large amount of rehabilitation expense (cable material expense, reparation labour cost, traffic expense etc.).

Description of drawings

Below, with reference to accompanying drawing, for those skilled in the art that, to detailed description of the present utility model, above and other purpose of the present utility model, feature and advantage will be apparent.

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

Embodiment

Shown in Figure 1, cable anti-theft clamp of the present utility model comprises guiding inner tube 1, is set in the outer guiding outer tube 2 of this guiding inner tube 1, an and guide pipe 5 that is set in guiding outer tube 2 rear ends, guide pipe 5 comprises guide part 51 and connecting portion 52, and the Zhou Jing of guide part 51 is greater than guiding outer tube 2.wherein, this guiding outer tube 2 comprises a guide part 21 and an extension 22 of front end, guide part 21 is hollow tubular, with the concentricity axle of guiding inner tube 1, and be set in the guiding inner tube 1 outside, gradually open and be the extension 22 that radiates taper in the rear end of guide part 21, tapered bottom end flange processing at extension 22, the connecting portion of guide pipe 5 is steel plates 51, these steel plate 51 vertical center axis also are fixed on the periphery wall of the guide part 51 of guide pipe 5, like this, by extension 22, form a cone space between guide part 51 and guiding inner tube 1, also be provided with four lock balls 3 and spring 4 in the zone of this cone space, wherein four lock balls 3 are embedded in four shrinkage pools that symmetry is offered on the caliber of guiding inner tube 1, one end of lock ball 3 is near the inwall of extension 22, the other end is fixed a spring 4, the other end of this spring 4 is fixed on guide part 51.

The utility model is when assembling, with extension 22 one ends sheathed enter of guiding inner tube 1 from guide pipe 2, simultaneously, when sheathed, four lock balls 3 are embedded in shrinkage pool, then, with between the sheathed end and guide part 51 that is fixed on lock ball 3 of spring 4, then, in the tapered bottom end flange processing of extension 22, with guide part 51, be integral structure.

When using, this fixture is embedded on cable 7, and namely cable 7 is located in guiding inner tube 1 from left to right,, due to spring 4 pretension compressions, ejects lock ball 3, and clamping cables 7, under the forwards effect of inertia, cause the cable firm grip, releases and draw tighter and tighter.

Spring of the present utility model can also replace with other and play the flexible member of said function.
