Abstract
The utility model provides a kind of bullet nail.The utility model includes tip nut, screw rod, elastic component and casing, tip nut center is circular cavity, the screw front end is connect with the tip nut, it is arranged with the elastic component and described sleeve pipe on the screw rod successively from front to back, the elastic component includes vertical tube part and hangnail portion, which is open towards the spiro rod rear end.Viscosity or fastness are stronger after the utility model makes it hammer into unlike material equipped with elastic component, and hangnail portion scatters to one end far from tip nut, and shock resistance and stretching resistance can be improved.
Description
Technical field
The utility model is related to a kind of bullet nails.
Background technology
Currently, universal nail is generally made of expansion sleeve, the screw rod with conehead and nut etc. in building, when installation
It drills on wall first, screw rod, expansion sleeve is put into hole and then is tightened nut and pulls screw rod, the conehead extruding of screw rod swollen
Mounted object is fixed on the wall by expansion set pipe so that the swelling that drills on expansion sleeve expanding end and wall.And it is general
Logical cylindrical either screw thread iron, steel nail are directly to squeeze into or be screwed into insert.The common bullet nail stretching resistance of above two,
Shock resistance is poor.
Invention content
The purpose of this utility model is to provide a kind of bullet nail, to overcome the above shortcomings.
To achieve the above object, the technical solution of the utility model is：A kind of bullet nail, including tip nut, spiral shell
Bar, elastic component and casing, tip nut center are circular cavity, and the screw front end is connect with the tip nut, should
It is arranged with the elastic component and described sleeve pipe on screw rod successively from front to back, the elastic component includes vertical tube part and hangnail portion, is somebody's turn to do
Hangnail portion is open towards the spiro rod rear end.
Further, the screw front end is equipped with screw thread, is equipped on screw thread, with screw rod in the circular cavity of the tip nut
Screw-thread fit, this kind of connection type be simply common.
Further, the elastic component and the tip nut are welded with the screw rod.
Further, described sleeve pipe is equipped with chamfering close to the one end in elastic component hangnail portion, and vertical tube part is sleeved on screw rod,
Thorn portion can be that petal-shaped is scattered outward.
Further, the elastic component vertical tube part and the diameter of described sleeve pipe are more than the diameter of tip nut rear end.
Further, the elastic component be elastic steel at.
Further, described sleeve pipe is duroplasts or aluminium alloy sleeve barrel.
The utility model has the beneficial effects that：Equipped with elastic component so that the utility model hammers into viscosity or jail after unlike material
Solidity is stronger, and hangnail portion scatters to one end far from tip nut, and shock resistance and stretching resistance can be improved；Making is simple, at
This is cheap, with obvious effects.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the vertical view of elastic component in the utility model.
In figure：1- tip nuts, 2- screw rods, 3- elastic components, 4- casings, 31- vertical tube parts, 32- hangnails portion.
Specific implementation mode
The utility model and its specific implementation mode are described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 to Fig. 2, the utility model includes tip nut 1, screw rod 2, elastic component 3 and casing 4, in tip nut 1
Centre is circular cavity, which connect with tip nut 1, is arranged with casing 4 and elasticity on the screw rod successively from front to back
Part 3, casing 4 is close to the rear end of screw rod 2.Elastic component 3 includes vertical tube part 31 and towards the hangnail portion 32 of 2 open rearward end of screw rod, screw rod 2
Rear end integrally formed with the head of a nail or can be screwed with the nut of cooperation, and the frictional force between hangnail portion 32 and insert can prevent whole
A bullet nail is pulled out.
2 front end of screw rod is equipped with screw thread, the screw-thread fit being equipped in the circular cavity of tip nut 1 on screw thread, with screw rod 2.
As another embodiment, can also be welded between elastic component 3 and tip nut 1 and screw rod 2.
1 front end of tip nut is tapering, and rear end is slightly justified, and facilitates entire bullet nail under external force, has huge kinetic energy, with
It can smoothly enter into insert.3 vertical tube part 31 of elastic component and the diameter of described sleeve pipe 4 are more than the diameter of 1 rear end of tip nut, are convenient for
Reinforce the viscosity of elastic component 3 and casing 4 and insert.
Elastic component 3 be elastic steel at.Casing 4 is equipped with chamfering close to the one end in elastic component hangnail portion 32.Casing 4 is hard plastic
Material or aluminium alloy sleeve barrel.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other relevant technical fields, are equally included in the patent within the scope of the utility model.
