Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model can be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
As shown in Figure 1-3, the utility model includes gun body 1, is set in the gun body 1 and is integrated with 1 die casting of gun body
Rifle core 2, be set to the rifle valve seat 3 of 2 front end of rifle core and be set to 2 inside of the rifle core and can only integral disassembly, assembly rifle
Needle assemblies；2 rear end of rifle core is provided with sealing screw 15 and cap 19.The rifle needle assemblies include rifle needle 7, be set to it is described
The spool 5 of 7 front end of rifle needle, embedded at 5 front end of spool valve ball 4 and from front to back set gradually be sleeved on rifle needle
Preloading spring 8, preceding retaining ring 9, interior seal pipe 10, bushing 11, outer sealed tube 12, rear retaining ring 13 and tail screw 14；The rifle needle 7
Front-end and back-end pass through after holding screw 6 is connected as an entirety with spool 5 and tail screw 14 and deforms the top of rifle needle 7 not respectively
Detachably.When the abrasion of valve ball 4 causes spray gun to be not closed completely to need replacing, can quickly by rifle needle assemblies integral disassembly, assembly, from
And the influence by maintenance of equipment to spraying application is preferably minimized.
It is set with top plate 16 on the tail screw 14 and axial position, 16 rear end of top plate and institute are adjusted by nut 17
It states and is provided with reset spring 18 between cap 19.One plane is set on 14 cylindrical surface of tail screw, on the sealing screw 15
One pin 21 is set, the end of the pin 21 is corresponding with the plane on 14 cylindrical surface of tail screw and there are gap, this
Sample can prevent from when dismounting nut 17 tail screw 14 to rotate skidding, and the axial direction of tail screw 14 moves back when not influencing to switch spray gun
It is dynamic.Trigger 23 is provided in the gun body 1, the trigger 23 passes through lateral pin 22 hingedly with the gun body 1, the trigger 23 and institute
It states and is provided with thimble 24 between top plate 16.
The S-shaped bending of feed pipe 20 in the gun body 1, bending design can make gun handle by moving back, allow
The finger of cocking is more farther with a distance from muzzle, and the coating leaked when spray gun being prevented to be not closed completely drips to operator's
On finger.
1 upper end of gun body is provided with the C-shaped hook 1A of opening backward, can hang up spray gun when not used, just
It is managed in storage.
The course of work of the utility model is as follows:
When finger pulls spray gun trigger 23, trigger 23 is elapsed top plate 16 by thimble 24 backward, and top plate 16 overcomes multiple
Position spring 18 resistance by nut 17 drive rifle needle assemblies overcome the resistance of preloading spring 8 to elapse backward, thus make valve ball 4 and
Gap occur between rifle valve seat 3 opens spray gun.When finger unclamps spray gun trigger 23, effect of the top plate 16 in reset spring 18
It is elapsed forward under power, rifle needle assemblies is driven to elapse forward, close spray gun so that the gap between valve ball 4 and rifle valve seat 3 be made to disappear
It closes.
When valve ball 4 or the abrasion of rifle valve seat 3, which cause spray gun to be not closed completely, needs replacing rifle needle assemblies, cap is removed first
19, reset spring 18 is taken away, nut 17 and top plate 16 are removed, can use after then removing rifle valve seat 3 to preceding tapping tail screw 14
Rifle needle assemblies out.After the rifle needle assemblies and rifle valve seat 3 that more renew, loading by above-mentioned order backward can restore to work normally.It is whole
A replacement process used time greatly shortens, and the influence to spraying application is preferably minimized, and avoids delaying spraying application progress.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
