Description

a spray gun

technical field

The utility model relates to a spray gun, in particular to a two-component manual spray gun for fluid spraying, referred to as "double-head spray gun".

Background technique

It is a two-component manual spray gun used for spraying paint, corrosion inhibitor, pickling liquid and other fluids.

Connect the air switch assembly to control air entry, the gun needle is set at a slightly higher position than the air switch assembly, its end is located in the gun head, and the tail is connected to the paint volume adjustment assembly. The disadvantages of this traditional two-component manual spray gun are that, first, because the gun needle and the paint adjustment assembly are arranged separately, and the air switch assembly is also arranged separately, resulting in a relatively complicated structure and many required parts, The processing procedure is more cumbersome, and the production cost is higher; second, due to the complex structure and many parts, it is more prone to failure, and it is not easy to maintain, the service life is shorter, and the operation is more cumbersome.

Utility model content

The technical problem to be solved by the utility model is to provide a two-component manual spray gun with simpler and more practical structure, more convenient maintenance and operation, and lower production cost.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions: a spray gun, including a gun head assembly, a gun body, a gun handle, a trigger, an air pipe, an air pipe joint, a paint amount adjustment assembly, a style adjustment assembly and a gun needle, The gun head assembly, gun handle, paint volume adjustment assembly and style adjustment assembly are installed on the gun body, the trigger is fixed on the gun body and connected with the gun needle, and the air tube is arranged in the gun handle, one end of which is connected to the air pipe joint and the other end is connected to the The air channel in the gun body; the gun body is also provided with a paint channel, the paint channel is connected to the paint pipe joint, the paint pipe joint is connected to the paint pipe, and the gun needle is connected to the oil seal gasket and passes out of the gun body. It is characterized in that: the spray gun is also provided with Copper sleeve, the front end of the copper sleeve is connected to the trigger, the rear end is sleeved with a spring, and the spring presses against the paint volume adjustment assembly; the gun needle passes through the trigger and the copper sleeve to connect the paint volume adjustment assembly; the copper sleeve is equipped with an air valve, and the air valve is set in the air passage.

Further, the air valve has a frustum-shaped structure, and a neck matching the structure of the air valve is provided in the air passage. When the trigger is released, the air valve blocks the neck of the air passage, and the air passage is closed. When the trigger is triggered the air passages open and compressed air enters.

Further, the connection between the copper sleeve and the gun body is provided with an air seal gasket for preventing air leakage.

Further, a venting screw is provided at the joint between the gun handle and the gun body.

Further, the gun head assembly includes an adjusting cap and an outer muzzle, the adjusting cap connects the gun head assembly and the gun body, the outer muzzle is provided with an inner core of the outer muzzle, and an inner core of the outer muzzle is arranged between the outer muzzle and the inner core of the outer muzzle. There is a small inner mouth for materials, and the end of the small inner mouth for materials exposed to the inner core of the outer mouth cover is sleeved with a sealing gasket.

The utility model is used to control the switch of the air passage by setting the air valve and the copper sleeve together, and the gun needle is arranged in the copper sleeve and connected with the paint volume adjustment assembly, so that the gun needle, the paint volume adjustment assembly and the air switch assembly are integrated. Together, it changes the traditional way of setting the gun needle, the paint volume adjustment assembly and the air switch assembly separately. The product structure is simpler, the parts are reduced, and the production cost is reduced.
