Abstract
The utility model discloses a kind of firing pin with cartridge chamber, the end of the firing pin is provided with cartridge chamber and tapped the head.The utility model sets cartridge chamber on firing pin, can provide expansion space for nail shooting pill explosion time, be finally reached the purpose of smooth ejection.
Description
Technical field
The utility model is related to nailing tightening technology field, relates in particular to a kind of firing pin with cartridge chamber, firing pin master
It is used for the percussion that box hat is penetrated.
Background technology
Nailing device is a kind of by the use of the powder gas for launching nail shooting pill generation as power, and nailing is squeezed into building body
Instrument.It is a kind of advanced modern tightening technology that nailing device, which is used for nailing tightening technology, with traditional pre-buried fixation, burrows and pours
Note, bolt-connection, the method such as welding is compared, and is had many advantages：The energy is carried, the burden of electric wire and airduct has been broken away from, has been easy to
Scene and work high above the ground；Operation is quick, short time limit, can largely mitigate the labor intensity of workmen；Saving fund, drop
Low construction cost.
In the prior art, nailing device generally uses plastic housing nail shooting pill for power or uses box hat nail shooting pill for power, and leads to
Cross firing pin to fire nailing, such as Chinese patent notification number is the prior art of " CN205704031 " in public affairs on November 23rd, 2016
A kind of push type nailing device is driven, its technical scheme is：Including firing lock and trigger mechanism, the firing lock includes percussion
Seat and the percussion post being arranged in percussion seat, the trigger mechanism include gun barrel, gun barrel fixed cover, gun barrel stage clip and firing pin, rifle
Pipe is slidably located in one end of gun barrel fixed cover, and the other end of gun barrel fixed cover, which is fixed, to be set on percussion seat, and firing pin includes hitting
Head, the body of rod and pedestal, tap the head with pedestal and to connect integral by the body of rod, tap the head in gun barrel, pedestal is located at percussion post
Percussion end, gun barrel stage clip is set on the body of rod, and gun barrel stage clip is located between gun barrel and pedestal.The principle of the patent is：In nail
Nail shooting pill is ignited by firing pin in pipe, so that nailing is fastened on matrix.But in actual application, due in nail pipe
Footpath is identical, and nail shooting pill, particularly box hat nail shooting pill can expand after blast and be close on the inwall of nail pipe, and this will result in
Shell case is stuck in nail pipe, and then causes shell case not exit smoothly.
Utility model content
The purpose of this utility model is solution the above-mentioned problems in the prior art, and there is provided a kind of hitting with cartridge chamber
Pin, the utility model sets cartridge chamber on firing pin, can provide expansion space for nail shooting pill explosion time, be finally reached smooth ejection
Purpose.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of firing pin with cartridge chamber, it is characterised in that：The end of the firing pin is provided with cartridge chamber and tapped the head.
The cartridge chamber is bellmouth.
The taper of the cartridge chamber is 0.8-1.2 degree.
Described to tap the head as sharp cone distal structure, the quantity tapped the head is at least one.
The end of the firing pin is fixedly connected with the cylinder that external diameter is more than firing pin external diameter, and the cartridge chamber and tapping the head is respectively provided with
On the cylinder.
Using the utility model has the advantage of：
First, the utility model is provided with Conical Projectile bore on firing pin, can be exploded by Conical Projectile bore for nail shooting pill
When expansion space is provided, reduce the frictional force between shell case and cartridge chamber, be finally reached easily the smoothly purpose of ejection.Meanwhile, lead to
The frictional force between nail shooting pill in the prior art and nail inside pipe wall can also be reduced by crossing cartridge chamber, be conducive to the use longevity of extension nail pipe
Life.
2nd, the taper of cartridge chamber is set to 0.8-1.2 degree by the utility model, is particularly suitable for use in the percussion of box hat nail shooting pill, is made
The ejection for obtaining box hat nail shooting pill is lighter.
3rd, the utility model sets tapping the head at least one sharp cone distal structure, is conducive to accurately igniting nail shooting pill.
4th, cartridge chamber and tapping the head is arranged at external diameter more than on the cylinder of firing pin external diameter by the utility model, is conducive to subtracting
The external diameter of small firing pin, reaches that reduction firing pin prepares the purpose of cost.

Embodiment
Embodiment 1
Cartridge chamber 2 is provided with a kind of firing pin with cartridge chamber, the end face of the end of the firing pin 1 and tap the head 3, the cartridge chamber 2
For bellmouth, the taper of the cartridge chamber 2 is 0.8-1.2 degree, and described tap the head 3 is sharp cone distal structure, it is described tap the head 3 quantity extremely
It is one less.
In the present embodiment, it is described tap the head 3 quantity for it is multiple when, multiple 3 ends for being symmetricly set on firing pin 1 of tapping the head.
Embodiment 2
Cartridge chamber 2 is provided with a kind of firing pin with cartridge chamber, the end face of the end of the firing pin 1 and tap the head 3, the cartridge chamber 2
For bellmouth, the taper of the cartridge chamber 2 is 0.8-1.2 degree, and described tap the head 3 is sharp cone distal structure, it is described tap the head 3 quantity extremely
It is one less.
In the present embodiment, the end of the firing pin 1 is fixedly connected with the cylinder 4 that external diameter is more than the external diameter of firing pin 1, the bullet
Thorax 2 and tapping the head 3 is arranged on cylinder 4.
Further, the cylinder 4 is integrally formed with firing pin 1 is made.
The utility model is mainly used in the percussion of box hat nail shooting pill 6, in use, box hat nail shooting pill 6 is counter mounted on into firing pin 1
In cartridge chamber 2（I.e. the explosive sealing end of box hat nail shooting pill 6 is located in cartridge chamber 2）, the nailing and plastics for being reloaded into integral structure be close
Block 5 is sealed, firing pin 1 makes box hat nail shooting pill 6 explode under the impact of spring force, because box hat nail shooting pill 6 is reverse installation, and
Cartridge chamber 2 is bellmouth, therefore under the promotion of gases at high pressure so that shell case goes out nail together with plastic seal block 5 and nailing
Pipe 7, so as to realize light ejection.
