Description

Technical Field

[0001] The utility model relates to the technical field of nozzle installation, in particular to an auxiliary installation structure for a spray gun nozzle. Background Art

[0002] In traditional spray gun nozzle installation, installation often relies on the operator's experience and simple manual alignment methods. It is easy for the nozzle to be not completely aligned with the internal flow channel of the spray gun. This misalignment may cause uneven distribution of the spraying liquid or gas, affecting the spraying quality. At the same time, the spray liquid in the spray gun is prone to contain impurities, causing the nozzle to be blocked. When the nozzle is not in use, dust is easily introduced, affecting the use of the nozzle. In order to solve the above problems, a spray gun nozzle auxiliary installation structure is needed.

[0003] The existing spray gun nozzle is not easy to install accurately during operation, cannot filter the spray liquid, and cannot prevent dust from entering the front end of the nozzle. Therefore, an auxiliary installation structure for the spray gun nozzle is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a spray gun nozzle auxiliary installation structure to solve the problems that the existing spray gun nozzle auxiliary installation structure is not convenient for precise installation, cannot filter the spray liquid, and cannot prevent dust from the front end of the nozzle when in use.

[0005] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: an auxiliary installation structure for a spray gun nozzle, comprising a spray gun rod, a side wall of the spray gun rod being provided with a limiting groove, an outer wall of the spray gun rod being provided with a clamping groove, a nozzle body being installed on the outer wall of the spray gun rod, a fixing frame being installed on the outer wall of the nozzle body, a limiting rod being installed on the inner wall of the fixing frame, and a limiting spring being installed on the outer wall of the limiting rod.

[0006] A sealing plate is installed on the inner wall of the nozzle body, and a filter screen is installed on the inner wall of the sealing plate.

[0007] A positioning rod is installed on the outer wall of the nozzle body, a dustproof plate is installed on the outer wall of the positioning rod, and a return spring is installed on the outer wall of the positioning rod.

[0008] Preferably, the spray gun rod is plugged into the nozzle body, and the limiting rod forms a telescopic structure with the fixing frame through a limiting spring.

[0009] Preferably, the limiting rods are distributed in a ring array with the central axis of the nozzle body as the center, and the limiting rods are engaged with the limiting grooves.

[0010] Preferably, the sealing plate is plugged into the slot, and the outer wall of the sealing plate is tightly fitted with the inner wall of the nozzle body.

[0011] Preferably, the positioning rod is movably connected to the dustproof plate, and the dustproof plate forms a telescopic structure with the positioning rod through a return spring.

[0012] Preferably, the dustproof plate is snap-connected to the nozzle body, and the dustproof plate is arranged as a convex shape.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a limit groove, a nozzle body, a fixing frame, a limit rod and a limit spring. The limit rod is pulled outward, and then the spray gun rod is inserted into the nozzle body. After the limit rod is released, the limit rod is squeezed inward by the elastic force of the limit spring, so that the limit rod and the limit groove are engaged and fixed. The coordinated use of the limit rod and the limit groove improves the disassembly and assembly efficiency of the nozzle body and facilitates replacement.

[0015] 2. The utility model is provided with a card slot, a sealing plate and a filter screen. The sealing plate is aligned with the card slot and inserted, and then the spray gun rod and the nozzle body are fixed. The setting of the sealing plate increases the sealing of the connection between the spray gun rod and the nozzle body to prevent water leakage, and the setting of the filter screen filters impurities in the water to prevent clogging inside the nozzle body.

[0016] 3. The utility model is provided with a positioning rod, a dustproof plate and a reset spring. When in use, the dustproof plate is pulled outward and then rotated. The nozzle body can be used normally. When the nozzle body is out of use, the dustproof plate is reset. The dustproof plate is squeezed by the reset spring to seal and block the front end of the nozzle body to prevent dust from entering. BRIEF DESCRIPTION OF THE DRAWINGS
