Description
Technical field
The utility model relates to a kind of combustion-type driver, particularly a kind of gas staple gun.
background technology:
At present, at gas staple gun on the market, be all to bear hitting power with plastic casing, wherein the endoporus of plastic casing bottom coordinates location with the cylindrical of cylinder bottom, and the bottom of cylinder is to be positioned on the step of plastic casing, because the not machinability of plastic casing and the distortion after plastic shaping and change in size all can cause the axial line disalignment of cylinder axial line and plastic casing, and can cause cylinder to change in axial size, and make the installation of cylinder and ailhead seat also axial deviation can occur.In addition, the cylinder head of all gas staple guns is to be all connected with the pre-buried screw on plastic casing top in the market, causes like this cylinder head and the skew of cylinder occurrence positions.The high temperature causing due to igniting, burning, blast in the use procedure of whole gas staple gun can make its plastic casing occur softening and expand, and has caused this product that change in size in use all can occur, or length variations.And more seriously: each igniting blast all can make plastic casing axially impact, and has the trend of drawing crack.After general nailing tens0000 times, this plastic casing will break.
The patent No. is to be that the utility model patent on April 25th, 2013 discloses a kind of gas staple gun the ZL201320216465.1 applying date, following feature is disclosed in the structure of this gas staple gun: " on the circumference external diameter of described cylinder block, being provided with plural connection boss; connect between boss and have the passage that air-flow passes through; connect boss and be connected with terminal pad by bolt; the bar-shaped trough that wherein has air-flow to pass through on terminal pad; one end of joint pin is connected on terminal pad, the other end is connected with the cylinder head that is positioned at cylinder block top ".In this patent, by being fixed on the terminal pad connecting on boss, come the mode of fastening connecting column to have following drawback: the first, although have hole on terminal pad, airflow effect is not fine.Meanwhile, if increase hole count or increase aperture, reduced the intensity of terminal pad self.The second, the existence of terminal pad, has increased the step of processing, and has improved production cost.
Utility model content
The purpose of this utility model is just to provide that a kind of can to cancel plastic casing stressed, improves service precision and the gas staple gun in service life.
To achieve these goals, by the following technical solutions:
A gas staple gun, is characterized in that: on the circumference external diameter of described cylinder block, be provided with plural connection boss, connect between boss and have the passage that air-flow passes through.
On the connection boss of described cylinder block excircle, have be connected boss one to one joint pin be connected boss and be connected.
The upper end of joint pin is connected with the cylinder head that is positioned at cylinder block top.
Described gas staple gun has and the joint pin retainer of half opening one to one, and this retainer is arranged on the inwall of heat insulation guard shield of gas staple gun and becomes as a whole with heat insulation guard shield.
Described heat insulation guard shield armrest has a side chamber that gas cylinder and the lever of calming the anger are installed.
Between the upper end of described heat insulation guard shield and cylinder head cover and cylinder head, there is end play, between heat insulation guard shield lower end and the outer wall of cylinder block, there is radial clearance.
This utility model project organization is compact, easy, and accurate positioning between parts, positioning precision are high, and antifatigue impulsive force is strong, is conducive to air-flow flowing between heat shield and cylinder block, can extend the service life of product, cuts down finished cost.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figures 1 to 5, a kind of gas staple gun, the adiabatic outer cover that comprises cylinder block 4 and cylinder block outside, on the circumference external diameter of described cylinder block 4, be provided with plural connection boss 4-1, connect between boss 4-1 and there is the passage that air-flow passes through, connect on boss and be drilled with hole, one end of joint pin 6 fixes with being connected boss through hole, and the other end is connected with the cylinder head 2 that is positioned at cylinder block top.Joint pin 6 directly fixes with being connected boss 4-1, has reduced processing technology, has reduced processing charges, passes through experiment test simultaneously, and this kind of connected mode can still can guarantee the bonding strength between two kinds.And reduced after terminal pad, the circulation of gas more smoothly, is conducive to air-flow flowing between heat shield and cylinder block.
The bottom of cylinder block has boss, the adiabatic guard shield armrest of cylinder block outside has a side chamber 3-2 that gas cylinder and the lever of calming the anger are installed, this chamber and heat shield are a monolithic construction, because the retainer of half opening makes its this chamber can well guarantee the position of gas cylinder with the firm connection of joint pin and cylinder head.
During installation, heat insulation lower shield is installed from bottom to up, just can be fixed.The retainer 3-1 that is provided with the half opening that holds joint pin on the inwall of heat insulation upper shield, joint pin can be embedded in retainer like this, has guaranteed the fixing of heat insulation guard shield.Between the upper end of heat insulation guard shield and cylinder head cover and cylinder head, there is end play, between heat insulation guard shield lower end and the outer wall of cylinder block, there is radial clearance.So in use because the raise expansion of the heat insulation guard shield of plastics cause of temperature can not affect the serviceability of this product, and change in size.
In this utility model, heat insulation guard shield only plays heat insulation effect, there is no support function, even if namely heat insulation guard shield is removed, does not also affect the function of nail gun at all.
Owing to having adopted technique scheme, the utlity model has design ingenious, easy to process, make precision high, extend the service life of whole nail gun.
