Description

Expansion screw propulsion device

Technical Field

The utility model relates to a advancing device specifically indicates an inflation screw advancing device.

Background

At present, most expansion screws mainly comprise a screw rod, an expansion pipe and other parts, wherein the tail part of the screw rod is conical, and the inner diameter of the cone is larger than that of the expansion pipe. When the nut is screwed down, the screw rod moves outwards, the conical part moves through the axial movement of the threads, so that a large positive pressure is formed on the peripheral surface of the expansion pipe, and the angle of the cone is small, so that friction self-locking is formed among the wall body, the expansion pipe and the cone, and the fixing effect is achieved. The fastening device is generally used for fastening guard rails, rain canopies, air conditioners and the like on materials such as cement, bricks and the like, and is also commonly used in underground places, house decoration and the like.

The following situations are often encountered during the installation of expansion screws, which result in difficult or poor installation: firstly, when the diameter of a drill hole is smaller or the drill hole is not formed at one time, the expansion screw plug cannot enter the hole; secondly, the sleeve pipe that the drilling diameter is greater than the inflation screw is too much, and the screw rod rotates with the nut during installation equally and is difficult to the installation, and the master worker often adopts the mode of hammering to pound into by force, and the mode of hammering often leads to the inflation screw card downthehole, can not reach the predetermined degree of depth promptly and also is difficult to pull out again, leads to the installation failure.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide an inflation screw advancing device.

In order to solve the technical problem, the utility model provides a technical scheme is an inflation screw advancing device, including the body of rod, connector, the body of rod just is overall structure with connector fixed connection, the body of rod is kept away from connector one end and is the body of rod head, the body of rod is close to body of rod head department and is equipped with symmetrical and evenly distributed's location spout, the body of rod one end is kept away from to the connector is equipped with the spread groove.

As an improvement, an anti-skid key protruding outwards is arranged in the positioning sliding groove.

As an improvement, the shape and the size of the rod body and the head of the rod body are matched with the shape and the size of the drill bit of the electric hammer.

As an improvement, the longitudinal section of the connecting groove is a closed circular arc.

As a refinement, the connecting body is in the shape of a cylinder.

Compared with the prior art, the utility model the advantage lie in: this device simple structure, reasonable in design, it is practical convenient, through the cooperation of this device and electric hammer drill, can squeeze into the wall body with the inflation screw quick, accurate, firm, effectively improve work efficiency.
