Description

Hidden nozzle type paint spray gun

Technical Field

The utility model belongs to the technical field of the spray gun, concretely relates to hide nozzle type paint spray gun.

Background

The spray gun utilizes compressed air generated by an air compressor, when the compressed air is sprayed out through an air cap at the front part of the spray gun, a low-pressure area lower than the atmospheric pressure is generated at the front part of a paint spray nozzle connected with the spray gun, the paint is sucked out of a paint storage tank through the pressure difference generated at the nozzle of the spray gun, and the paint is atomized into particles and sprayed on the surface of an object to be coated under the action of high-speed jet force of the compressed air. The existing spray gun is usually communicated with the spray gun through a paint pipe for continuous spraying, so that continuous paint is obtained. However, during operation, the long length of paint tube can interfere with gun movement and operation; furthermore, the existing spray gun is usually placed on a table top after use, which may cause nozzle contamination and affect the spraying quality, and chinese patent 201620612996.6 discloses a spray gun for spraying operation, which can solve certain technical problems, but the nozzle of the spray gun is still prone to contamination, so the applicability and the practicability are limited.

Disclosure of Invention

The utility model aims at providing a structure sets up reasonable and suitability strong hidden nozzle type paint sprayer.

The technical scheme for realizing the purpose of the utility model is a hidden nozzle type paint spray gun, which comprises a paint spray gun, a handle arranged on the paint spray gun and a trigger arranged on the handle, wherein a paint pipe and an air pipe are fixed on the paint spray gun, a mixing cavity is arranged in the paint spray gun, the paint pipe is communicated with the mixing cavity, the air pipe is communicated with the mixing cavity through the handle, a nozzle is arranged at the outlet of the paint spray gun, a spraying circular pipe communicated with the mixing cavity is arranged in the paint spray gun, the length of the spraying circular pipe is less than the distance between the mixing cavity and the spraying end of the paint spray gun, a convex ring is fixed at the outer end of the spraying circular pipe, a circular groove is arranged on the inner wall of the nozzle, the width of the circular groove is greater than that of the convex ring, the convex ring is positioned in the circular groove, and a reset spring is fixed between the convex ring and the end wall of the circular groove, the nozzle is in shrink in paint spray gun under the effect of spring paint spray gun is last to be provided with L shape and to stick up the pole, paint spray gun is last to be provided with vertical spout, the L shape sticks up the corner of pole and is in through round pin hub connection in the vertical spout, the L shape sticks up the one end of pole and passes through the loose axle and connect on the nozzle and the other end is fixed on the trigger during the trigger lock, thereby L shape sticks up the pole and uses the round pin axle to remove as the center rotation and in vertical spout and drive the nozzle and outwards stretch out paint spray gun.

And a rubber sealing layer is adhered to the inner wall of the annular groove, and the convex ring is positioned in the annular groove and is attached to the rubber sealing layer.

The inner diameter of the spray gun is the same as that of the spraying circular tube.

And a hanging ring is fixed at the upper end of the paint spray gun.

The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, the simple operation, and its nozzle contracts when not using, when pulling at the trigger and making the air hose switch on, makes the nozzle stretch out the paint spray gun to can realize the protection to the nozzle, use reliable and stable, the suitability is strong and the practicality is good.
