Description

Technical Field

[0001] This utility model relates to the field of spray gun nozzles, specifically a corrosion-resistant spray gun nozzle. Background Technology

[0002] The spray gun nozzle is a key component of the spray gun. Structurally, spray gun nozzles are usually made of metal and have specific shapes and sizes. They are generally conical or cylindrical with a very small spray hole at the front end. Spray gun nozzles are widely used in various fields, such as automobile manufacturing, furniture painting, and building decoration. Spray gun nozzles are needed when spraying workpieces. Currently, spray gun nozzles are often fixed by bolts, which makes disassembly and assembly inconvenient. Therefore, a corrosion-resistant spray gun nozzle is needed.

[0003] Existing spray gun nozzles are inconvenient to replace and install according to actual spraying needs. Operators often cannot quickly and easily change to the appropriate nozzle according to actual needs, which greatly limits the flexibility of spray gun use. In addition, the current nozzles have poor corrosion resistance, which affects the service life of the nozzles. Therefore, there is an urgent need for a corrosion-resistant spray gun nozzle. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a corrosion-resistant spray gun nozzle to solve the problems of existing spray gun nozzles being inconvenient to replace and install according to actual spraying needs and having poor corrosion resistance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a corrosion-resistant spray gun nozzle, comprising a spray gun mounting block, a retaining ring fixedly connected to the outer wall of the spray gun mounting block, a nozzle cylinder mounted on the outer wall of the spray gun mounting block, a receiving plate fixedly connected to the outer wall of the nozzle cylinder, a rotating shaft movably connected inside the receiving plate, a limit rod fixedly connected to the outer wall of the rotating shaft, and a nut movably connected to the outer wall of the limit rod.

[0006] The inner wall of the nozzle cylinder is fixedly connected to a ceramic composite coating, and the inner wall of the ceramic composite coating is fixedly connected to a polyurethane coating.

[0007] Preferably, the spray gun mounting block is engaged with the nozzle cylinder, and the limiting rod is movably connected with the retaining ring.

[0008] Preferably, the limiting rod forms a rotating structure with the receiving plate via a rotating shaft, and the limiting rod is T-shaped.

[0009] Preferably, the outer wall of the limiting rod is provided with threads, and the limiting rod is threadedly connected to the nut.

[0010] Preferably, the nozzle barrel and the ceramic composite coating are in close contact, and the nozzle barrel and the ceramic composite coating are arranged in parallel.

[0011] Preferably, the ceramic composite coating and the polyurethane coating are tightly bonded together, and the ceramic composite coating and the polyurethane coating are arranged in parallel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of a spray gun mounting block, retaining ring, nozzle cylinder, receiving plate, rotating shaft, limiting rod and nut, allows one end of the spray gun mounting block to be inserted into the nozzle cylinder by moving the nozzle cylinder. Pulling the limiting rod, under the action of the rotating shaft, can cause the limiting rod to flip along the receiving plate and be locked into the groove of the retaining ring. Rotating the nut can cause the nut to squeeze the outer wall of the retaining ring, which can facilitate the replacement and installation of the nozzle cylinder according to the actual spraying needs, thereby improving the flexibility of the spray gun.

[0014] 2. This utility model, through the setting of a nozzle cylinder, a ceramic composite coating, and a polyurethane coating, with the ceramic composite coating fixedly connected to the inner wall of the nozzle cylinder, can improve the impact resistance of the nozzle cylinder, and the polyurethane coating fixedly connected to the inner wall of the ceramic composite coating can improve the corrosion resistance of the nozzle cylinder, thereby extending the service life of the nozzle cylinder.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4 A corrosion-resistant spray gun nozzle includes a spray gun mounting block 1, a retaining ring 2 fixedly connected to the outer wall of the spray gun mounting block 1, a nozzle cylinder 3 mounted on the outer wall of the spray gun mounting block 1, a receiving plate 4 fixedly connected to the outer wall of the nozzle cylinder 3, a rotating shaft 5 movably connected inside the receiving plate 4, a limiting rod 6 fixedly connected to the outer wall of the rotating shaft 5, and a nut 7 movably connected to the outer wall of the limiting rod 6. The spray gun mounting block 1 and the nozzle cylinder 3 are engaged, and the limiting rod 6 is movably connected to the retaining ring 2. The limiting rod 6 forms a rotating structure with the receiving plate 4 through the rotating shaft 5, and the limiting rod 6 is T-shaped. The outer wall of the limiting rod 6 is threaded, and the limiting rod 6 is threadedly connected to the nut 7, which facilitates the replacement and installation of the nozzle cylinder 3, so that the diameter of the nozzle cylinder 3 can be adapted to the corresponding spraying process.

[0023] Please see Figure 1-4 A corrosion-resistant spray gun nozzle has a ceramic composite coating 8 fixedly connected to the inner wall of the nozzle cylinder 3, and a polyurethane coating 9 fixedly connected to the inner wall of the ceramic composite coating 8. The nozzle cylinder 3 and the ceramic composite coating 8 are tightly bonded and arranged in parallel. The ceramic composite coating 8 and the polyurethane coating 9 are also tightly bonded and arranged in parallel, which can improve the corrosion resistance of the nozzle cylinder 3.

[0024] Working principle: In use, select the nozzle cylinder 3 of the required diameter, move the nozzle cylinder 3 so that one end of the spray gun mounting block 1 is inserted into the nozzle cylinder 3, rotate the nozzle cylinder 3 so that the position of the limiting rod 6 corresponds to the groove of the retaining ring 2, pull the limiting rod 6, and under the action of the rotating shaft 5, the limiting rod 6 can be flipped along the receiving plate 4 and locked into the groove of the retaining ring 2. Rotate the nut 7, since the nut 7 is threadedly connected to the limiting rod 6, the nut 7 can squeeze the outer wall of the retaining ring 2 after rotation, so that the spray gun mounting block 1 and the nozzle cylinder 3 are tightened and installed. The ceramic composite coating 8 is fixedly connected to the inner wall of the nozzle cylinder 3, which can improve the impact resistance of the nozzle cylinder 3. The polyurethane coating 9 is fixedly connected to the inner wall of the ceramic composite coating 8, which can improve the corrosion resistance of the nozzle cylinder 3.
