Abstract

The utility model provides a structure of a low-pressure high-flow spray gun and particularly relates to the structural design of the spray gun, which can adjust air flow and exert pressure on a paint cup. The low-pressure high-flow spray gun is mainly characterized in that an air flow adjustment component is arranged on the side edge close to a gun head; a rotatable pressurization connector is arranged at the back end and in a position close to a gun hook; the air flow adjustment component can be closed or can adjust the flow of air passing through the connector, changes the spraying area and spraying distance of the spray gun head; the rotatable pressurization connector can provide an optimal angel when a paint cup pressurization pipe is connected with the pressurization connector, and ensures that the paint cup stably provides the amount of paint required when the spray gun works.

Description

The structure of low-pressure high-flowrate spray gun for paint

[technical field]

The utility model is the structure about a kind of low-pressure high-flowrate spray gun for paint, espespecially a kind of spray gun for paint is adjusted the structural design of air-flow and pressurization paint cup, be bordering on rifle head side, be provided with an air-flow adjustment group and nearly rifle hook rear end be provided with one can turn pressurizing adaptor, the flow that air-flow passes through can be closed or adjust to this air-flow adjustment group, and the area and the distance that change lance head ejection are provided; Pressurizing adaptor that can turn can provide the paint cup best angle that forcing pipe connects, and required paint amount when guaranteeing that paint cup is stable spray gun for paint work being provided.

[background technology]

Existing spray gun for paint, as shown in No. 241571st, Taiwan notification number, its air-flow adjustment and rifle header structure are combined into one, adjust when air-flow flow required when user can spray compared with instinct type adjustment, but as shown in its Fig. 1, it can be by the aperture of air-flow and area little, under the state of low pressure, to maintain high flow capacity and will have certain difficulty, due to low pressure relation, the paint vehicle of paint bottle is under siphon principle, its paint vehicle flow is relatively not high, and spray gun for paint fails to provide the supply of pressurization, easily produces paint vehicle feeding deficiency in painting process, and for example shown in Taiwan certificate number M315117 patent, the rifle body first half is located in its air-flow adjustment, adjust knob and be located at body of a gun rear, during for user's operation adjustment, a hand-held gun, another hand adjustment is whole, the relevant position space of two hands is not quite enough, therefore while adjustment, there is its not part smoothly, and because adjustment extends to nearly rifle head place with a straight-bar by rifle rear with part, except affecting flow, also may cause sinuous flow, and then stability while hindering spray gun jet-impingement, though this is commonly used product and is provided with paint cup pressurization joint, but because fixing position, in the time that hindering to some extent, operation cannot give suitable adjustment and inconvenience to some extent.

[utility model content]

Holder, is arranged with the first drop-stopping ring and is fixed at the approximate flow channel of the falling Y shape end of rifle body group;

Pressurizing adaptor seat, its one end is arranged with the second drop-stopping ring, is hubbed in holder, and anchors position with an E shape, and other end periphery proximal end face place spiral shell is established a pressurizing adaptor.

Wherein, middle rifle body group, its nearly rifle head rear adjusting seat, this seat mouthful inner side spiral shell is provided with screw thread, and nearly screw thread place is provided with a plane; Rifle head extends back approximate fall the flow channel of Y shape, one runner connects with the seat end of the adjusting seat of nearly rifle head rear side, the approximate flow channel of falling Y shape end medial margin spiral shell is provided with screw thread.

Wherein, air-flow is adjusted assembly, its one end is hubbed in the adjusting seat of rifle body group, this end is an approximate tubular, be concaved with by its end the breach that air feed stream passes through, nearly outer peripheral edges place is provided with the first plane and the second plane, and mutually at angle, this two plane is just corresponding to the near plane at screw thread place in the adjusting seat of rifle body group for the first plane and the second plane.

Wherein, holder one end is concaved with one, and the seat end has provided a hole.

Wherein, pressurizing adaptor seat, one end-face pivot place is concaved with a pore, and other end periphery proximal end face place is provided with a screw that runs through pore, and spiral shell is established pressurizing adaptor.

The utility model advantage and effect are: 1. the flow channel sectional area in rifle body group is not subject to mechanics limit, can obtain larger air flow rate.2. the sinuous flow that can reduce therein air current flow in runner without too many mechanism, improves the steady quality of the work of spraying paint.3. adjust knob-operated space enough, and meet the operating position of ergonomics.4. when a paint cup forcing pipe connects pressurizing adaptor, can angle-adjustable to meet the demand that operates spray gun.
