Description
Technical field
The utility model belongs to the structural member interconnection technique field of nail, and in particular to a kind of steel nail for being easy to extract.
Background technology
Steel nail is a kind of widely used connection firmware, since its role is to be connected and fixed, people are often desirable to
Connecting material is fixed surely and secured by steel nail.204,572,679 204755520 U and CN of U, CN of patent document CN
205244064 U are all based on this purpose and are improved to the structure of steel nail.
But on the other hand in some cases, connecting material can be securely fixed using steel nail is not intended merely to when steel nail, together
When also want to easily pull out after steel nail hammers into material.Existing steel nail will be pulled out after hammering into material not only to be compared
It is harder, and connecting material may be damaged.
Utility model content
Extract relatively elaborate and the problem of may be damaged to connecting material after being hammered into for above-mentioned steel nail, this practicality is new
Type provides a kind of steel nail for being easy to extract, its object is to：Make steel nail that can firmly fix connecting material but also easily pull out
Out.
The technical solution adopted in the utility model is as follows：
A kind of steel nail being drawn out easily, including steel nail point, steel nail bar and steel nail head have a cavity, steel nail head inside steel nail bar
On be provided with cavities open, cavity includes cavity epimere and cavity hypomere, and the cavity epimere is located adjacent to one end of steel nail head,
The cavity hypomere is located adjacent to one end of steel nail point, and cavity hypomere shape is cone, conical zenith directions and steel nail
The direction of point is consistent, and steel ball is provided in cavity, and connecting rod is provided on steel ball, and connecting rod is stretched out outside cavities open.
After the technical solution, when steel nail hammers into, steel ball is allowed to head into cavity hypomere, circular cone of the steel ball to cavity hypomere
The cavity wall in face generates extruding, causes steel nail point and steel nail bar that slight expansion occurs close to the position of steel nail point, therefore can be secured
Ground hammers into the material for needing to connect.When needing to extract steel nail, steel ball is set to retract cavity epimere connecting rod force, at this moment
The extruding that the cavity wall of the circular conical surface of cavity hypomere is subject to disappears, to make steel nail point and steel nail bar close to the light of the position of steel nail point
Microdilatancy also disappears, and steel nail point and steel nail bar are sized to be slightly smaller than the nail being tufted on material close to the position of steel nail point at this time
Hole, therefore be very easy to extract, when extraction, is very laborsaving and will not destroy the material being tufted into.
Preferably, one end of connecting rod stretching cavities open is provided with connecting-rod cap.Be arranged connecting-rod cap can conveniently pair
Connecting rod exerts a force to control the position of steel ball.
Preferably, steel ball is spherical or elliposoidal, the cone that the diameter of steel ball cross section is formed with the cavity hypomere
Basal diameter match.The cavity wall of the circular conical surface preferably to cavity hypomere may be implemented in steel ball selected by the preferred embodiment
The effect squeezed.
Preferably, the length of connecting rod is consistent with the length of cavity epimere.The length of connecting rod needs to ensure to make steel ball can
To head into cavity hypomere and squeeze the cavity wall of circular conical surface.
It is further preferred that cavity epimere shape is the cone of vertex opening, the direction of vertex opening and steel nail are first
It causes, the cavities open is located at the vertex opening of the cone of cavity epimere formation, the circle that in other words cavity epimere is formed
The vertex opening of taper is exactly cavities open.When using the preferred embodiment, during extracting steel nail, when steel ball is retracted into cavity
When epimere, the circular conical surface cavity wall of cavity epimere can be squeezed, cause the epimere of steel nail bar that slight expansion occurs.On steel nail bar
The expansion of section disappears with the expansion of steel nail bar hypomere causes nail hole integrally to become a kind of taper of transversal inward-facing reduction, further makes
It is very convenient to obtain steel nail extraction.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：
1. when steel nail hammers into, steel ball generates extruding to the cavity wall of the circular conical surface of cavity hypomere, causes steel nail point and steel nail
Close to the position of steel nail point slight expansion occurs for bar, therefore can hammer into the material for needing to connect securely.
2. when needing to extract steel nail, steel ball is set to retract cavity epimere connecting rod force, at this moment cavity hypomere
The extruding that the cavity wall of circular conical surface is subject to disappears, to make steel nail point and steel nail bar also disappear close to the slight expansion at the position of steel nail point
It loses, steel nail point and steel nail bar are sized to be slightly smaller than the nail hole being tufted on material close to the position of steel nail point at this time, therefore very
It is easy to extract, when extraction is very laborsaving and will not destroy the material being tufted into.
3. cavity epimere is shaped to the cone of vertex opening.During extracting steel nail, when steel ball is retracted into sky
When chamber epimere, the circular conical surface cavity wall of cavity epimere can be squeezed, cause the epimere of steel nail bar that slight expansion occurs.Steel nail bar
The expansion of epimere disappears with the expansion of steel nail bar hypomere causes nail hole integrally to become a kind of taper of transversal inward-facing reduction, further
So that steel nail extraction is very convenient.
4. the steel nail extracted is reusable, material is saved.
