Abstract

The utility model relates to a screw with a hole, which belongs to a fastener. The utility model is characterized in that a small hole with a certain depth and a certain diameter is arranged along the axial direction of the screw in the center of a nut. The main purpose is that after the screw is used with a corresponding screw cone, the screw is convenient to be accurately and quickly aligned with a screw thread hole, and assembly efficiency is improved.

Description

Bleed screw

The utility model relates to a kind of fastening piece, refers to screw especially.

At present, known screw in assembly process because can not be freely, location exactly, at small space, can't be directly with the place of finger alignment screw, it is very difficult to aim at screw, in the deep and long hole of apart from each other, or on non-horizontal surface during to the hole, its difficulty is bigger.Like this, greatly limited the efficient of assembling work.

The purpose of this utility model, be design a kind of can any space angle can both be exactly, freely on the screw of screw.

The purpose of this utility model is achieved like this: at the nut center of screw, along the axle center aperture that certain depth and certain diameter are arranged is arranged, its size can be arranged or standardization.And on the axle center of gimlet, a flexible freely little pin being arranged, the diameter of pin and extrusion with the diameter and the degree of depth coupling of aperture on the screw, after this gimlet is magnetized, produce certain suction to screw.Screw and gimlet form a same axis body like this, can aim at tapped hole in the small space of any work surface exactly, freely.

It is convenient and reliably that the utility model implements, and its great advantage is with after corresponding gimlet coupling is used, and can improve the working efficiency of some assembling works exponentially.This effect in some electrical equipment or machinery assembling is very tangible.

Below, the utility model is described in further detail with exemplary embodiments in conjunction with the accompanying drawings.

Fig. 1 is the plan view of exemplary embodiments;

Fig. 2 is the axial sectional view of exemplary embodiments;

Among the figure, 1, nut, 2, " one " word groove, 3, positioning hole, 4, screw thread.

Exemplary embodiments is example with cutting on the nut for " one " font, and positioning hole has axially locating and radial location effect in actual applications simultaneously, and it is much simple that the processing of " one " word groove is wanted, and its Economy, practicability are obvious.The positioning hole processing of its alloytype nut also is the same, no longer enumerates at this.

Claims

1, bleed screw, its structure, shape, size are identical with corresponding standard screws, are primarily characterized in that: at the center of nut, along the screw axis direction aperture that certain depth and certain diameter are arranged is arranged.
