Rapid assembly and disassembly electric spray gun

Abstract

The invention relates to a rapid assembly and disassembly electric spray gun which comprises a container, a tuyere, an enclosure, a motor and the like. A rapid assembly and disassembly structure comprises a gun body seat (1), an inner pipe (3) and a button (9) sleeved on the outer wall of the inner pipe (3); the outer diameter of the gun body seat (1) is less than the inner diameter of the inner pipe (3); the outer wall of the gun body seat (1) is provided with two bumps (11); the inner wall of the inner pipe (3) is provided with axial guide slots (31) and radial through holes (39), which are matched with the bumps (11); the button (9) consists of a button part (91) and two lug parts (92); the button part (91) is connected with the top end of the inner pipe (3) by an elastic part (8); the lug parts (92) are provided with convex strips (94) towards the side of the inner pipe (3); each convex strip (94) is divided into an upper convex strip and a lower convex strip (95) by a cross slot (93); and a lateral surface (951) of each lower convex strip (95), which faces the corresponding upper convex strip, is matched with the corresponding bump (11). According to the invention, by utilizing a simple mechanical structure, rapid installation or disassembly between the gun body seat and the inner pipe of the electric spray gun is implemented and the spray gun can be conveniently washed and maintained.

Description

technical field [0001] The invention relates to a spray gun, in particular to a quick loading and unloading electric spray gun which can atomize paint, paint or similar media to workpieces through airflow. Background technique [0002] The common structure of existing electric spray gun is made up of parts such as container, gun body seat, inner tube, casing, motor. Among them, the gun body seat, motor and inner tube are directly fixed in the casing, and the gun body seat and the inner tube are mostly connected in one piece. The disadvantage of this structure is that the cleaning and maintenance of the spray gun is extremely inconvenient, and because the motor is directly fixed Inside the casing, there is a safety hazard when cleaning the gun body seat of the spray gun. In response to this shortcoming, a connection structure in which the gun body seat and the inner tube are separated gradually appeared. Adopt threaded connection as CN202162104, although can effectively sol...
