Description

A kind of electrostatic gun

Technical field

The utility model relates to a kind of coating spraying equipment.Be specifically related to a kind of electrostatic gun.

Background technology

At present, the electrostatic gun of selling on the market mainly is made up of rifle body, handle, trigger.The thimble that also comprises fluid hose, paint valve, paint in the described rifle body.This normally used liquid electrostatic spray gun, opening the paint valve is to rely on Bearing Angle to move backward directly to retract the thimble of oil sealing lacquer, thereby opens paint.The Bearing Angle power of moving backward wherein derives from operating personnel's hand, and the size of power can influence the size of amount of paint.As inhomogeneous may the causing that exert oneself the inhomogeneous of amount of paint, again because the thimble rear end of oil sealing lacquer has spring that it is made the power that adds forward (in order to seal paint when the not triggering pulling).So can relatively require great effort during operative employee's cocking, and this normally used liquid electrostatic spray gun cannot convert automatic job to and use, can only manual working.

The utility model content

The purpose of this utility model provides a kind of easy to operate, stability of flow, and the electrostatic gun that can freely change of automatic or manual.

In order to achieve the above object, the utility model has following technical scheme:

A kind of electrostatic gun of the present utility model, comprise the rifle body, rifle body handle, trigger, the touching switch of handle top, be positioned at the paint valve of rifle body front end, the paint pump that is connected with paint valve by fluid hose, source of the gas, also comprise electrostatic generator, magnetic valve in the electrostatic generator, automatic/hand change-over switch on the electrostatic generator, power supply, cylinder, the cylinder expansion link, wherein, the coil of the magnetic valve of electrostatic generator is connected with the touching switch by power supply, the coil of the magnetic valve of electrostatic generator is connected with the automatic/hand change-over switch again by power supply, magnetic valve is connected with cylinder with source of the gas respectively by air hose, one end of cylinder expansion link is connected with the piston of cylinder, and the other end is connected with paint valve.

Wherein, the touching switch of described rifle body handle top comprises swivel nut, button, spring, push rod, binding post, lead-in wire, line cover, wherein, push rod passes swivel nut and is connected with button, spring housing contacts on push rod and with button, swivel nut is fixed on rifle body handle top, and binding post is fixed on and the corresponding rifle body of swivel nut handle top, and the line cover is enclosed within on the lead-in wire of binding post.

Wherein, described swivel nut comprises is with externally threaded screwed pipe, nut, and screwed pipe is connected with an end of nut or makes one, the junction of nut and screwed pipe be provided with the annular that is used to keep out spring every.

Wherein, spray gun is by the touching touching switch on the Bearing Angle touching handle, open the magnetic valve in the electrostatic generator, have air flow stream to go in the interior cylinder of electrostatic gun handle after magnetic valve is opened, the expansion link of cylinder moves backward at once, thus the thimble of pulling oil sealing lacquer, realize opening paint, because trigger only to the touching switch application of force, so the operator only need use the valve that very little power just can realize opening paint, has the labour-saving characteristics.

Wherein, the power of the pulling oil sealing thimble of described spray gun is that cylinder applies, so the operator can not influence the size of amount of paint to the size variation of the trigger application of force, so oil pump capacity is even.

Wherein, described touching switch is two switches in parallel with the automatic/hand change-over switch.So can realize automatic and manual conversion.When the automatic/hand change-over switch rotates to when automatic, spray gun does not need operating personnel's cocking just can spray paint work..When the automatic/hand change-over switch rotates to when manual.Need operating personnel's cocking just can spray paint work, operating personnel automatically, manually can select on demand.

Owing to taked above technical scheme, advantage of the present utility model is:

1 the utility model is by the touching switch on the Bearing Angle touching handle, open magnetic valve, after opening, magnetic valve have air flow stream to go in the interior cylinder of electrostatic gun handle at once, active cylinder expansion link at air pressure moves backward, thereby the thimble of pulling oil sealing lacquer, realize opening paint, because trigger is only to the touching switch application of force, so the operator only need use the valve that very little power just can realize opening paint; Have the labour-saving characteristics.

2 and because the power of pulling oil sealing thimble is that cylinder applies, so the size variation of operator's application of force can not influence the size of amount of paint, oil pump capacity is even.

3 described touching switches are two switches in parallel with the automatic/hand change-over switch.So can realize automatic and manual conversion. when the automatic/hand change-over switch rotates to when automatic, spray gun does not need operating personnel's cocking just can spray paint work. when the automatic/hand change-over switch rotates to when manual. need operating personnel's cocking just can spray paint work. operating personnel automatically, manually can pacify to be needed to select.
