Description

Technical Field

[0001] The utility model relates to the technical field of lamp pole processing, in particular to a spray nozzle. Background Art

[0002] After light poles, such as composite light poles, are processed and formed, they need to be coated with an anti-corrosion layer on the outside to improve their corrosion resistance. Currently, when spraying the anti-corrosion layer, operators directly apply it using a spray gun. This spraying method easily allows the anti-corrosion coating to enter the air, causing air pollution. Furthermore, this spraying method also has poor uniformity during the spraying process. Utility Model Content

[0003] The utility model provides a spray nozzle to solve the deficiencies of the above-mentioned prior art, solves the problem that the anti-corrosion paint easily pollutes the air when spraying, and also improves the uniformity during spraying, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A spray nozzle includes an outer ring plate, with end rings provided at the upper and lower ends of the outer ring plate, respectively. The upper end ring is provided with two pairs of locking screws, and an upper baffle is movably mounted on the locking screws. The inner end of the upper baffle is provided with an arcuate groove, and the upper baffle is provided with a pair of guide holes, through which the locking screws pass. A conical cover is provided on the inner circumference of the lower end ring, with the upper end of the conical cover being the small end. A connecting ring is provided on the inner wall of the outer ring plate, and the inner circumference of the connecting ring is connected to multiple nozzles. The connecting ring is connected to a connecting pipe, which passes through the outer ring plate. The space formed by the outer ring plate, the end rings, and the conical cover prevents the anti-corrosion coating from diffusing outward and causing environmental pollution during spraying. The nozzles arranged in a circular array can improve spray uniformity during spraying. To further enhance the uniformity of the coating and the protective effect, a baffle is also provided.

[0006] Furthermore, the conical cover is made of rubber to improve the sealing effect between the conical cover and the rod body.

[0007] Furthermore, the lower end of the outer ring plate is provided with a convex edge, on which multiple rotating shafts are rotatably mounted, and gears are mounted on the rotating shafts, which are meshed with racks, which are covered with limit sleeves, which are mounted on the convex edge, and the gears are meshed with a gear ring, which is provided with an L-shaped ring inside the gear ring, which is mounted on the end ring at the lower end, and an L-shaped head is provided on the inner end of the rack, and a roller is rotatably mounted on the inner end of the L-shaped head. The roller facilitates the operator to move the spray head during spraying, and because the movement of the roller is driven by a gear ring, it ensures that each nozzle is at an equal distance from the rod body, thereby improving the uniformity of the spraying.

[0008] Furthermore, a screw rod is provided on one of the rotating shafts, and a tightening sleeve is provided on the screw rod. The inner end of the tightening sleeve is tightened on the convex edge. The setting of the tightening sleeve facilitates the locking of the rotating shaft, thereby improving the stability during spraying.

[0009] The advantages of the above technical solution are:

[0010] The utility model facilitates the uniform spraying of the composite lamp pole and can also prevent a large amount of paint from entering the air during the spraying process, thereby affecting the production environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0014] Figure 3 Shows a three-dimensional structure of one embodiment Figure 3 . DETAILED DESCRIPTION

[0015] like Figures 1 to 3 As shown, a spray nozzle for spraying includes an outer ring plate 1, and end rings 10 are respectively provided at the upper and lower ends of the outer ring plate 1. Two pairs of locking screws 2 are provided on the end ring 10 at the upper end. An upper baffle 30 is movably provided on the locking screw 2. An arc groove is provided at the inner end of the upper baffle 30, and a pair of guide holes 21 are provided on the upper baffle 30. The locking screws 2 pass through the guide holes 21. A conical cover 13 is provided on the inner periphery of the end ring 10 at the lower end. The upper end of the conical cover 13 is a small end, and the conical cover 13 is made of rubber.

[0016] A connecting ring pipe 14 is provided on the inner wall of the outer ring plate 1 . The inner periphery of the connecting ring pipe 14 is connected to a plurality of nozzles 15 . The connecting ring pipe 14 is connected to a connecting pipe which passes through the outer ring plate 1 .

[0017] The lower end of the outer ring plate 1 is provided with a flange 11, on which a plurality of rotating shafts 3 are rotatably mounted. A gear 40 is mounted on the rotating shaft 3, which is meshed with a rack 31. A limiting sleeve 32 is mounted on the rack 31. The limiting sleeve 32 is mounted on the flange 11. The gear 40 is meshed with a gear ring 37. An L-shaped ring 38 is mounted within the gear ring 37. The L-shaped ring 38 is mounted on the end ring 10 at the lower end. An L-shaped head 35 is mounted on the inner end of the rack 31. A roller 36 is rotatably mounted on the inner end of the L-shaped head 35. A screw 33 is mounted on one of the rotating shafts 3, which is provided with a tightening sleeve 34. The inner end of the tightening sleeve 34 is tightened against the flange 11.

[0018] When operating this embodiment, the operator first sets the nozzle on the circular composite lamp pole.

[0019] Then adjust the position of the upper baffle 30, and lock the upper baffle 30 by locking the screw 2. After the upper baffle 30 is fixed, there is a small gap between its inner circumference and the rod body, and the thicker coating can be scraped evenly after the spraying is completed.

[0020] Then the operator rotates one of the rotating shafts 3 through the screw 33. The rotation of one of the rotating shafts 3 will drive the gear 40 to rotate, and the rotation of the gear 40 will drive the gear ring 37 to rotate. The rotation of the gear ring 37 will drive each gear 40 to rotate. When the gear 40 rotates, it will drive the rack 31 to move inward. When the rack 31 moves inward, the roller 36 will be tightly attached to the outer periphery of the lamp pole.

[0021] Finally, the anti-corrosion paint is pumped into the connecting ring pipe 14 through the pump, and then sprayed out from the nozzle 15, and the nozzle 15 is sprayed onto the rod body. During the spraying process, the operator moves the nozzle until the spraying operation is finally completed.

[0022] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Therefore, if such modifications and variations fall within the scope of the claims and their equivalents, the present invention is intended to include such modifications and variations.
