Description

A kind of pipeline anti-theft device

One, technical field

The utility model belongs to the pipe installation technical field, especially relates to a kind of pipeline anti-theft device.

Two, background technology

Development along with urban construction, the laying of various pipelines more and more widely, because the needs of beautifying urban environment, various pipelines are generally all laid with burying, because pipeline contains various metal materials, thereby stolen phenomenon happens occasionally, the stolen economic loss that causes of pipeline, annual arriving up to more than one hundred million units, though be provided with burglar alarm in the existing pipeline and be equipped with the tour personnel, but because pipeline is longer, the stolen phenomenon of pipeline still can't be avoided.

Three, summary of the invention

The purpose of this utility model be to improve the deficiency of prior art and provide a kind of simple in structure, cost is low, the pipeline anti-theft device of good anti-theft effect, easy installation and removal.

The purpose of this utility model is to realize like this, a kind of pipeline anti-theft device, be characterized in being provided with the pipeline hole at the center of disk body, be provided with the dop main body on disk body, dop main center is penetrating hole, the from bottom to top contraction gradually of the diameter in hole, the wall in hole is provided with expansion slot vertically, conical dop rises by external diameter that core can put into the hole inner chamber and the core that rises greater than the hole internal diameter, and the core center of rising is provided with the hole of band boss, and fastening bolt can be connected as a single entity the dop main body and the core that rises by two holes.

In order further to realize the purpose of this utility model, can be that the hole outer wall of dop main body is provided with anti-slip tank.

In order further to realize the purpose of this utility model, can be that described disk body is that a pair of disk body butt joint becomes one, the disk body joint is provided with the pipeline hole.

In order further to realize the purpose of this utility model, can be that the side, hole of the dop main body on disk body is provided with penetrating removal hole.

In order further to realize the purpose of this utility model, can be on disk body, to be provided with at least 4 dop main bodys and evenly distribution.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts and is provided with the pipeline hole at the center of disk body, the dop main body is arranged on disk body, dop main center is penetrating hole of from bottom to top shrinking gradually, the wall in hole is by axially being divided into the two parts that link together, the conical dop core that rises can be put into the external diameter of the hole inner chamber and the core that rises greater than the hole internal diameter, draw in the hole of dop main body by core that dop is risen like this, the hole wall that is the dop main body separates, tightly pipeline and penetration pipe are lived in extruding, make it to interfix, guaranteed that pipeline can not pulled out in penetration pipe, the hole outer wall of dop main body is provided with the screw thread anti-slip tank, increased frictional force, guaranteed interfixing of pipeline and penetration pipe, disk body is divided into two parts, made things convenient for the installation and removal construction, increase work efficiency, the side, hole of dop main body is provided with penetrating removal hole, the core that can easily dop be risen like this takes out from the dop main body, so that field-strip, disk body is provided with at least 4 dop main bodys and evenly distributes, and has guaranteed the fixed-site of pipeline in penetration pipe, be unlikely to because the position deviation of pipeline influences the effect of anti-theft device.
