Abstract
The utility model discloses a spray gun which comprises a gun body, a spray mouth and a trigger. The trigger is connected with a gas switch valve rod, a needle plug sleeve and a needle plug respectively. The gas switch valve rod, a gas switch valve and a gas switch spring are connected in sequence. A gas switch screw and a gas switch sealing pad are arranged on the connection portion of the gas switch valve rod and the gun body. A needle plug sealing screw and a needle sealing pad are arranged on the needle plug, and sealing performance is improved. An amplitude adjusting rod is arranged above the needle plug sleeve and the needle plug. The spray gun is simple in structure and convenient to operate, the sealing structure is optimized, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of spray gun, particularly a kind of spray gun for industries such as spraying, spray paint.
Background technology
Spray gun is a kind of common spraying equipment, it is mainly processed the atomization of coating by spray gun, then spray painting in surface of the work, can be so that surface to be machined obtains attractive in appearance, uniform coat, it is unreasonable that some present spray guns arrange because of structure, and parts are various, not easy to assemble, poor sealing causes the phenomenons such as gas leakage or leakage body, has reduced the qualification rate of production efficiency and product.
Utility model content
The purpose of this utility model is to provide a kind of parts less in order to solve above-mentioned the deficiencies in the prior art, and good airproof performance is simple and easy to the spray gun filling.
To achieve these goals, the spray gun that the utility model is designed, comprise rifle body, nozzle, trigger, the gentle switch spring of air cock valve, it is characterized in that: described trigger is connected with air cock valve rod, pin plug sleeve and pin plug respectively, the gentle controlled valve of described air cock valve rod, air cock spring connect successively, the junction of air cock valve rod and rifle body is provided with air cock screw, air cock sealing gasket, increases thus sealing property; Pin is provided with pin plug sealed screw and pin plug sealing gasket beyond the Great Wall, is provided with an amplitude adjusted bar above pin plug sleeve and pin plug, is convenient to thus regulate the size of air-flow.Amplitude adjusted bar is to be threaded with gas flow-regulating screw; Pin plug is to be threaded with pin plug sleeve, and connected mode is convenient to adjust.The other end of pin plug spring is provided with pin plug adjusting nut and pin plug set screw, is convenient to for regulating the size of nozzle.Pin plug sleeve is placed on pin plug spring the inside, and simple in structure being convenient to dismantled.
The spray gun that the utility model obtains, reasonable in design simple in structure, easy to operate, thereby optimized hermetically-sealed construction, improved the efficiency of assembling and the qualification rate of product.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1:
As shown in Figure 1, the spray gun that the present embodiment provides, comprise rifle body 1, nozzle 2, trigger 6, the gentle switch spring 12 of air cock valve 11, trigger 6 respectively with air cock valve rod 7, pin plug sleeve 13 is connected with pin plug 3, the gentle controlled valve 11 of described air cock valve rod 7, air cock spring 12 connects successively, when cocking 6, air cock valve rod 7 can utilize the elastic force of air cock spring 12 to make air cock valve 11 separated with air cock seat 18 under the effect of external force, same hour hands plug sleeve 13 at cocking 6 also can utilize the elastic force of pin plug spring 16 to drive pin plug 3 under the effect in external force, open nozzle 2.Pin plug 3 is to be threaded with pin plug sleeve 13, and pin plug sleeve 13 is placed on pin plug spring 16 the insides.When air cock valve 11 is opened, gas flows into gas channel.As shown in Figure 2, for preventing that gas from leaking outside, air cock valve rod 7 is provided with air cock screw 8, air cock sealing gasket 9 with the junction of rifle body 1, and as shown in Figure 4, pin plug 3 is provided with pin plug sealed screw 4 and pin plug sealing gasket 5, increases thus sealing property; Above pin plug sleeve 13 and pin plug 3, be provided with an amplitude adjusted bar 17, as shown in Figure 3, amplitude adjusted bar 17 is to be threaded with gas flow-regulating screw 10, the other end of pin plug spring 16 is provided with pin plug adjusting nut 15 and pin plug set screw 14, when gas flows to the gas channel at amplitude adjusted bar 17 places, can regulate by gas flow-regulating screw 10 size of valve.Below pin plug 3, near nozzle 2 places, have into painting screw 19, innerly during near gas channel gas flows to nozzle 2 can produce siphonage, coating is sucked in, then together with gas from nozzle 2 ejections.
