Abstract
The utility model discloses a spray gun comprising a body and a head part, wherein the head part is detachably connected with the body and comprises a nozzle, an airflow cap and a parallel cap; the tail end of the nozzle is communicated with the liquid path of the spray gun; the spray-head part of the nozzle is sleeve-jointed in the center hole of the airflow cap; the parallel cap is detachably connected with the body; the airflow cap is in press fit with the body through the parallel cap; the spray gun also comprises a rotation positioning disc and a spring; the rotation positioning disc is in press-fit between the airflow cap and the body through the spring; one end of the spring presses against one side, facing the body, of the rotation positioning disc; the other end of the spring presses against the body; a positioning structure is arranged between the rotation positioning disc and the airflow cap to lead the two to be circumferentially positioned; and one side of the rotation positioning disc, facing the body, is provided with a circumferential limiting structure. The spray gun has the following advantages: when rotating the airflow cap, the rotation positioning disc can not rotate due to the circumferential limiting of the body, at the same time, the positioning structure arranged between the rotation positioning disc and the airflow cap functions to realize circumferential accurate positioning of the airflow cap.
Description
Technical field
The utility model relates to a kind of spray gun, specifically is a kind of spray gun that is used to industries such as spraying, spray paint.
Background technology
The existing spray gun that is used to industries such as spraying, spray paint, generally include body and head, described head is connected with body is detachable, described head comprise nozzle, air-flow cap and and cap, the tail end of described nozzle communicates with the liquid road of spray gun, the showerhead of described nozzle is socketed in the centre bore of air-flow cap, and described and cap is connected with body is detachable, and described air-flow cap is by also cap and body interference fit.There is a problem in this structure, between the air-flow cap of existing gun head and the body is that face contacts, when on regulating the air-flow cap, being distributed in the circumferential position of typing pore of shower nozzle the right and left, be difficult to accurate location, the typing air-flow of certain position such as horizontal direction or vertical direction can't be accurately located, and then the coating of vertical direction or horizontal direction can't be sprayed accurately.
The utility model content
Technical problem to be solved in the utility model is that a kind of spray gun that can accurately circumferentially locate the air-flow cap is provided.
For solving the problems of the technologies described above, the spray gun that the utility model provides, comprise body and head, described head is connected with body is removable, described head comprises nozzle, the air-flow cap and and cap, the tail end of described nozzle communicates with the liquid road of spray gun, the showerhead of described nozzle is socketed in the centre bore of air-flow cap, described and cap is connected with body is removable, described air-flow cap is by also cap and body interference fit, it also comprises rotational positioning disc and spring, described rotational positioning disc is force-fitted between air-flow cap and the body by spring, one end of described spring and rotational positioning disc offset towards the one side of body, the other end and the body of described spring offset, be provided with between described rotational positioning disc and the air-flow cap and make both circumferentially location structures of location, described rotational positioning disc is provided with circumferential position limiting structure towards the one side of body.
After adopting above structure, a kind of spray gun of the utility model compared with prior art has the following advantages:
Spring offsets rotational positioning disc and air-flow cap, rotate the air-flow cap, but the rotational positioning disc is because of by circumferential spacing can not the rotation of body, and the location structure that be arranged between rotational positioning disc and the air-flow cap this moment plays a role, and realizes circumferentially accurately locating of air-flow cap.
As preferably, being provided with the location structure that both are circumferentially located between described rotational positioning disc and the air-flow cap is meant, the one side of described rotational positioning disc object gas flow cap along the circumferential direction on average is provided with projection, and described air-flow cap along the circumferential direction on average is provided with the depression that matches and use with projection towards the one side of rotational positioning disc.
Described projection is a spherical surface hill, and described depression is the sphere depression.This structure makes in the relative slip of basic overdraught cap that guarantees the location and rotational positioning disc more smooth and easy.
Described rotational positioning disc is provided with circumferential position limiting structure towards the one side of body and is meant that described rotational positioning disc is provided with projection towards the one side of body, and described body is provided with the groove that matches with projection.
Described projection is two, is separately positioned on the two ends up and down of rotational positioning disc, and described groove is two, is separately positioned on the two ends up and down of body and head junction.
