Description

Technical Field

[0001] The utility model relates to the technical field of paint spray nozzles, in particular to a uniform spray nozzle for spraying paint on automobile sheet metal. Background Art

[0002] Automotive sheet metal spray painting is a common automotive restoration technique, primarily used to repair deformed parts of a vehicle's metal exterior. During the painting process, a spray nozzle is a common application tool. The nozzle operates by evenly spraying paint at high pressure, creating tiny droplets that coat the surface of the sheet metal, not only repairing damage but also improving safety and reducing oxidation.

[0003] However, existing nozzles often spray unevenly during use, resulting in uneven thickness on the surface of sheet metal parts, affecting the painting effect. In addition, the nozzle aperture is fixed and cannot be selectively sprayed according to the particle size of the paint, which has low practicality. Utility Model Content

[0029] Through the above structure, the rotating head 2 is rotated, and the positioning rod 9 is inserted into the positioning groove 7 at different positions under the action of the telescopic spring 10. When the fine-pore spray hole 1 3 and the fine-pore spray hole 2 5 are aligned, the aperture is small at this time, which is suitable for spraying paint with fine particles and suitable for spraying in fine places. When the coarse-pore spray hole 1 4 and the coarse-pore spray hole 2 6 are aligned, the aperture is large, which is suitable for spraying paint with coarse particles and suitable for wide spraying. This design can adjust the aperture size according to the paint, has strong practicality, and makes the spraying more uniform.

[0030] Combined with attachment Figure 2 As shown, the fine-hole spray hole 1 3 and the fine-hole spray hole 2 5 are each provided with two circles, the coarse-hole spray hole 1 4 and the coarse-hole spray hole 2 6 are each provided with two circles, and the number of each circle is six. The angle between the centers of two adjacent coarse-hole spray holes 1 4 and coarse-hole spray holes 2 6 is 30°, and the angle between two adjacent positioning grooves 7 is 30°. A threaded groove 16 is provided on the outer surface of the end of the nozzle body 1 away from the rotating head 2.

[0031] Through the above structure, the staggered arrangement of coarse hole spray hole 1 4 and coarse hole spray hole 2 6 can control whether the paint is sprayed from the coarse hole. The design of the threaded groove 16 at one end of the nozzle body 1 is convenient for connection with the feed pipe on the paint spraying device and is easy to disassemble and clean.

[0032] Example 2

[0033] On the basis of embodiment 1, combined with the attached Figures 2 to 5 As shown, a sealing groove 11 is provided between the adjacent fine-pore spray hole 3 and the coarse-pore spray hole 4, a sealing ring 12 is provided in the rotating head 2 at a position corresponding to the sealing groove 11, and the sealing ring 12 is rotatably arranged in the sealing groove 11, a rotating groove 13 is provided on the nozzle body 1, and an annular clamping plate 14 is provided on the inner wall of the rotating head 2, and the clamping plate 14 is slidably located in the rotating groove 13, and a splash-proof shell 15 is provided on the rotating head 2, and the depth of the splash-proof shell 15 is 20-40 cm.

[0034] Through the above structure, the setting of the sealing ring 12 ensures the sealing of the connection between the rotating head 2 and the nozzle body 1, preventing leakage of paint or other fluids. The cooperation between the clamping plate 14 and the rotating groove 13 ensures the stability of the rotation of the rotating head 2 on the nozzle body 1, preventing the rotating head 2 from falling off. The setting of the splash-proof shell 15 prevents paint from splashing during spraying and contaminating surrounding objects.

[0035] The specific usage is as follows:

[0036] Thread one end of the nozzle body 1 into the threaded end of the feed pipe on the paint spraying device. When in use, the paint spraying device delivers paint to the nozzle body 1. If you spray coarse-grained paint, rotate the rotating head 2 so that the coarse-hole spray hole 1 4 and the coarse-hole spray hole 2 6 are aligned. At this time, the paint is sprayed from the larger aperture, the spraying speed is faster, and the paint flow rate is large, which is suitable for rough spraying of sheet metal parts.

[0037] If you are spraying paint with fine particles, rotate the rotating head 2 to align the fine-pore spray hole 1 3 and the fine-pore spray hole 2 5. The positioning rod 9 is inserted into the positioning groove 7 at the corresponding position under the action of the telescopic spring 10. At this time, the paint is sprayed out from a smaller aperture, the spraying is fine, and the paint flow rate is relatively small. It is suitable for fine spraying of the details of sheet metal parts, making the coating more uniform.

[0038] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
