Description
[technical field]
The utility model relates to pneumatically follow closely field, and in particular to a kind of pneumatic nail with cavity.
[background technique]
Nail used in compressed-air power rifle is referred to as pneumatic gun nail, referred to as pneumatic nail.With the day of pneumatic tool
Benefit is universal, and the nail that people use changes there has also been corresponding.The common nails such as the most common iron nail, steel nail in the past, now with
More more options are had the type pneumatically followed closely by appearance point: straight nail, volume nail, flat nail, pneumatic nail, wave follow closely, steel nail, Gan Bi
Nail etc. is had by model point: J sprig, F sprig, K-type nail, T-type nail, ST sprig, N-type nail etc. according to different purposes, are matched
Different air guns is covered to be used.
However, pneumatic nail in the prior art is usually rigid contact with fixated body, it is under vibrating conditions, pneumatic to follow closely
Lack stress release approach, easily cause pneumatic nail fracture, or fixated body is caused to crack with the contact position pneumatically followed closely,
Damping capacity can be assigned in such a way that rubber material package is pneumatically followed closely, but there are rubber material with pneumatically follow closely combined it is insecure,
And rivet nut and the larger problem of fixated body frictional force during nailing.
Therefore, how to provide it is a kind of be easy to nailing and can satisfy damping property demand it is pneumatic nail be that this field urgently solves
Certainly the technical issues of.
[utility model content]
The purpose of this utility model is to provide a kind of pneumatic nails for being easy to nailing and can satisfy damping property demand, should
The special construction pneumatically followed closely allows user in the demand for having vibration-damping function, can meet this by injection thermoplastic elastomer (TPE)
Demand, while not increasing the resistance of nailing again.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of pneumatic nail with cavity, including the head of a nail, rivet nut and ailhead, wherein rivet nut includes stem and cylindrical housing,
Stem is made of the cylindrical body for being located at rivet nut center with the multiple fan-shaped cylinders for being evenly distributed on cylinder circumference, cylindrical body and circle
Cylindrical outer casing is connected by fan-shaped cylinder, and cylindrical body, fan-shaped cylinder and cylindrical housing are an integral molding structure, cylindrical body and circle
Between cylindrical outer casing have a plurality of cavities as made of fan-shaped cylinder interval, also, the cylindrical housing of cavity area have engrave
Hollow structure, the head of a nail have the identical axial pass-through holes of multiple sizes, and the axle center of multiple axial pass-through holes is evenly distributed on along circle
On the head of a nail, and axial pass-through holes are connected to cavity.
Preferably, the axial length ratio of the head of a nail, rivet nut and ailhead is 1:5:3.
Preferably, the outer surface of the head of a nail, rivet nut and ailhead has silicon nitride coating.
Preferably, the quantity of fan-shaped cylinder is 4-6.
Preferably, the quantity of axial pass-through holes is identical as number of cavities.
Preferably, engraved structure is the circular hole along axial spaced set.
Preferably, engraved structure is axially disposed slot.
The pneumatic nail with cavity of the utility model uses the rivet nut of special construction, while ensure that rivet nut intensity,
Rivet nut can be made to have several for injecting the cavity of thermoplastic elastomer (TPE), in nailing, rivet nut enters after fixated body again
Thermoplastic elastomer (TPE) is injected, nailing resistance is effectively reduced, while pneumatic nail vibration-damping function, hollow out knot can be assigned according to demand
The setting of structure enables thermoplastic elastomer (TPE) to overflow cavity and contact with fixated body, is improving rivet nut and fixated body knot
While resultant force, the damping pneumatically followed closely can be further enhanced, in addition, what silicon nitride coating can effectively prevent pneumatically following closely
Corrosion.
