Abstract

A spray gun comprises a gun barrel, a handle with trigger arranged at the back-end of the gun barrel, a high voltage electrostatic generating device. The gun barrel comprises an upper powder spray pipe and a lower electrostatic generating pipe. A projecting gun head is arranged on the end of the powder sprat pipe. A metal ring with an electrostatic needle is arranged inside the gun head and a cap with a jet is arranged outside the gun head to fix the metal ring inside the gun head. The high voltage electrostatic generating device is arranged inside the lower electrostatic generating pipe. A switch controlled by the trigger is arranged on the handle. The utility model is characterized in that: the upper powder spray pipe and the lower electrostatic generating pipe are made of plastic materials and two pipe are connected together with a connecting block; a head sleeve comprising a upper head sleeve and a lower head sleeve is arranged on the end of the gun head; the cavity of the upper head sleeve communicates with the cavity of the lower head sleeve and the gun head is arranged on the upper head sleeve communicating with the cavity of the upper head sleeve. Compared to the prior technique, the utility model has the advantages that: the whole gun can not be scrapped even if the gun head is fractured; the control switch is easy to be assembled and changed; the shape is beautiful.

Description

A kind of spray gun

Technical field:

The utility model relates to a kind of spraying spray gun.Existing high pressure electrostatic painting is made with lucite with the rifle body of spray gun, its structure mainly is made of gun barrel, the handle that has trigger, high-voltage electrostatic generator, gun barrel is made of last discharge tube, following electrostatic generator pipe, the termination of discharge tube is provided with outstanding rifle head, be provided with the becket that has the static pin in the rifle head, the rifle head is provided with outward becket is fixed on the lid that has spout in the rifle head, high-voltage electrostatic generator is arranged on down in the electrostatic generator pipe, and a switch by spanner control is set on handle.During use; by the work of spanner control high-voltage electrostatic generator; produce high-pressure electrostatic around making the static pin on the discharge tube of rifle head; the powder that is driven by air-flow that spray part pipe inspection is come out flows high-pressure electrostatic on the interior powder belt; when the powder that has high-pressure electrostatic is run into the metal works surface that needs electrostatic spraying; will stick in securely on the metal works, make the metal works surface form a firm protective layer.This kind spray gun during use, is subjected to the influence of environment for use because the rifle head is reinstated lucite integral body with gun barrel one and made, and the rifle head is often bumped and knocks, and it is disconnected that the rifle head is often bumped, if the rifle head disconnects, a then whole spray gun is just ineffective.Handle is clamped together by two blocks of lucite and forms, and switch just is installed in two formed cavitys of lucite, as if assembling, replacing switch, just two blocks of lucite separately just can must be carried out, and like this, assembles, repairs just very inconvenient.In addition, adopt lucite to process spray gun, be subjected to the restriction of cost and processing technology, spray gun outward appearance water caltrop is clearly demarcated, moulding is stiff, attractive in appearance inadequately.

Summary of the invention:

Even goal of the invention of the present utility model is to provide a kind of rifle head rupture, can not cause the spray gun that whole rifle scrapped, gauge tap assembles, replacing is easy, handsome in appearance yet.

The utility model is to realize like this, comprise gun barrel, be connected gun tube rear end and have the handle of trigger, high-voltage electrostatic generator, gun barrel is by last discharge tube, following electrostatic generator pipe constitutes, the termination of discharge tube is provided with outstanding rifle head, be provided with the becket that has the static pin in the rifle head, the rifle head is provided with outward becket is fixed on the lid that has spout in the rifle head, high-voltage electrostatic generator is arranged on down in the electrostatic generator pipe, one switch by spanner control is set on handle, its special feature is discharge tube, the material of following electrostatic generator pipe is plastic cement and connects in aggregates by contiguous block each other, on the termination of rifle, be provided with headgear, headgear is by last headgear, following headgear constitutes, last headgear, following headgear inner chamber communicates up and down, the rifle head be arranged on the higher authorities put and with last headgear intracavity inter-connection.During work, pull trigger, connect the power supply of high-voltage electrostatic generator, the becket that has the static pin that has that is communicated with high-voltage electrostatic generator by lead obtains high pressure, form the high-voltage electrostatic field around making the static pin, just be with static when the powder in the powder stream that is driven by air-flow that spray part pipe inspection comes out is flowed through the high-voltage electrostatic field, just can be bonded in the surface of the work of metal when making powder run into the metal works surface securely.Because the rifle head is arranged on the headgear, even the rifle head in use disconnects, as long as changing headgear just can change the rifle that damages first watch, avoided whole spray gun to scrap because of the damage of rifle head, simultaneously, because last discharge tube, down the electrostatic generator pipe is a tube completely, made things convenient for last discharge tube, the electrostatic generator pipe comes out with plastic injection-moulded together with contiguous block is whole down.Make the handsome in appearance of spray gun.

Here, in order to strengthen the integral rigidity of gun barrel, the firm degree that discharge tube, following electrostatic generator pipe connect in the raising is provided with reinforcement on contiguous block.

In order to assemble easily and simplified structure, handle is made of two unit of plastics in front and back, is provided with the perforation corresponding with gun barrel above the handle, is provided with interlayer in the handle of trigger back, is provided with clip in the interlayer, and switch is arranged in the clip.Like this, when assembling, service switch, only need trigger is removed, clip is taken out in the interlayer of handle, just can carry out, and need not take apart by handle.

Be inlaid with short copper pipe in the termination of last discharge tube, short copper pipe is connected with high-voltage electrostatic generator by lead.During use, when being enclosed within the gun barrel termination right overhead, becket that has the static pin on the headgear and copper pipe fluid-tight engagement together, like this, high-voltage electrostatic generator just is connected with the becket that has the static pin, makes and forms the high-voltage electrostatic field around the static pin.When the rifle head damages, whole rifle is changed first watch, because the existence of copper pipe, when changing the rifle head, need not be connected with high-voltage electrostatic generator by the becket that lead will have a static pin, like this, just made things convenient for replacing, the maintenance of rifle head.

Compared with the prior art the utility model even have the rifle head rupture, can not cause the advantage that whole rifle scrapped, gauge tap assembles, replacing is easy, handsome in appearance yet.
