Abstract

The utility model discloses an expansion nail including a nail body and an expansion pipe. The expansion nail is characterized in that one half pipe wall of the expansion pipe is a stamping wave pipe wall, and the other half pipe wall of the expansion pipe is a plane pipe wall. The expansion pipe is provided with a whole expansion seam and at least a half expansion seam. The expansion nail has the advantages that the expansion pipe is formed by performing one-step die stamping to a sheet iron; when the nail body enters the expansion pipe, the whole expansion seam and the half expansion seam are pressed to expand, at the same time the waves on the pipe wall can brace the inner hole of a fixture, and the wave structure of the expansion pipe enables the pipe wall of the expansion pipe to have a certain elasticity and prevents the nail body from getting loose from the fixture, while the other half pipe wall is designed to the plane pipe wall, thereby having the tensile resistance function to the nail body and enabling the fastening effect to be more obvious.

Description

A kind of expandable nail

Technical field

The utility model relates to a kind of nail, especially a kind of expansion nail.

Background technique

Nail is one of requisite object in the daily production of people, the life, especially building field, decorate industry, furniture manufacturing industry, to consume number considerable.In the market at the nail of selling all size size, it generally is the metal body that roughly is the T type, nose circle face and the cylindrical body below it had both been comprised, and the end apicule of this cylinder, during actual the use, knock the nose circle face with hard thing such as hammer, this nose circle face will be taken advantage of a situation and be hammered in the object body, and is this traditional fixing cylindrical of an object time, after the end of nail is knocked in this body of wall, produce pressure can't for the cylindrical body of nail because of lacking elasticity around the body of wall, so when practical application, nail is drawn out easily, both the stretching resistance of nail was weak, of long duration, nail itself also becomes flexible easily and deviates from, and adopts the fixing fastness of nail not strong.Existing a kind of expandable nail on the market, as shown in Figure 2, at the external expansion tube that increased of nail, but because expansion tube is the plane tube wall, the fixing fastness effect of this expandable nail still is not ideal enough.

Summary of the invention

Development purpose of the present utility model is to overcome the deficiencies in the prior art, and a kind of effective expandable nail simple in structure, fastening is provided.

A kind of expandable nail of the present utility model comprises nail body, expansion tube, and it is characterized in that: half tube wall of described expansion tube is a punching press ripple glaze tube wall, and second half tube wall is the plane tube wall.

Described expansion tube has the halfbody dilatation joint of an entire body dilatation joint and at least one.

The beneficial effects of the utility model are: expansion tube is to utilize a punch die moulding of iron sheet, when the nail body enters in the expansion tube, the entire body dilatation joint and the halfbody dilatation joint of expansion tube are extruded expansion, the tube wall ripple can be at fixture endoporus stretching simultaneously, and the ripple struction of expansion tube makes the expansion tube tube wall have certain elasticity, makes the nail body can not become flexible on fixture, and second half tube wall is the design of plane tube wall, can have the tension effect to the nail body, make fastening effect more obvious.

Among the figure: 1: nail body, 2: expansion tube, 3: entire body dilatation joint, 4: halfbody dilatation joint, 5: ripple glaze tube wall, 6: plane tube wall.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further elaborated, as shown in Figure 1: a kind of expandable nail of the present utility model, comprise nail body 1, expansion tube 2, it is characterized in that: described expansion tube 2 half tube wall are punching press ripple glaze tube wall 5, and second half tube wall is a plane tube wall 6.

Described expansion tube 2 has the halfbody dilatation joint 4 of an entire body dilatation joint 3 and at least one.

The beneficial effects of the utility model are: expansion tube 2 is to utilize a punch die moulding of iron sheet, when nail body 1 enters in the expansion tube 2, the entire body dilatation joint 3 and the halfbody dilatation joint 4 of expansion tube 2 are extruded expansion, the tube wall ripple can be at fixture endoporus stretching simultaneously, and the ripple struction of expansion tube 2 makes the expansion tube tube wall have certain elasticity, makes the nail body can not become flexible on fixture, and second half tube wall is 6 designs of plane tube wall, can have the tension effect to the nail body, make fastening effect more obvious.

Claims

1, a kind of expandable nail comprises nail body, expansion tube, and it is characterized in that: half tube wall of described expansion tube is a punching press ripple glaze tube wall, and second half tube wall is the plane tube wall.

2, a kind of expandable nail according to claim 1 is characterized in that: described expansion tube has the halfbody dilatation joint of an entire body dilatation joint and at least one.
