[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Referring to Figures 1-3 , a multi-angle adjustable nozzle for a spraying device includes a nozzle body 1. An extended mounting ring 2 is screwed outside the nozzle on one side of the nozzle body 1. A flow cavity and a through cavity are sequentially provided in the middle of the extended mounting ring 2. A fixed seat 32 is arranged on one side in the through cavity. The periphery of the outer wall of the fixed seat 32 is connected to the extended mounting ring 2 through a limit fixing screw 33. An extension rod is installed on the top of the fixed seat 32. A limit block 31 is installed on the top of the extension rod. Guide plates 34 are rotatably installed around the periphery of the outer wall of the limit block 31, and the other side of the guide plate 34 is movably connected to the limit fixing screw 33. Limit nuts 35 are screwed on both sides of the outer wall of the limit fixing screw 33 where the guide plate 34 is located.

[0020] Moreover, a guide block is installed on the top of the limit block 31. The guide block is conical, and the top of the guide block is an inclined surface from the center to the outside.

[0021] Meanwhile, grooves are formed around the outer wall of the limit block 31, a fixed shaft is arranged in the grooves, and a guide plate 34 is rotatably installed on the outer wall of the limit block 31 through the fixed shaft.

[0022] Meanwhile, limit fixing screws 33 are fixedly and horizontally installed around the outer wall of the fixed seat 32, and the other ends of the limit fixing screws 33 are connected to the extended installation ring 2.

[0023] Furthermore, the diameter of the flow cavity is larger than that of the through cavity, and the diameter of the through cavity gradually increases from the side close to the flow cavity to the side away from the flow cavity.

[0024] Furthermore, an activity cavity is formed in the guide plate 34 at the position of the limit fixing screw 33, and the diameter of the activity cavity is larger than that of the limit fixing screw 33.

[0025] An external thread portion 21 is arranged on the outer wall of the side of the extended installation ring 2 away from the fixed seat, and an installation groove 11 is formed on one side of the nozzle body 1 at the position of the extended installation ring 2. An internal thread portion is adaptively arranged in the installation groove 11 at the position of the external thread portion 21, and the internal thread portion is in threaded connection with the external thread portion.

[0026] In this embodiment, by rotating the limit nut 35, the guide plate 34 rotates under the action of the fixed shaft, so as to guide the paint sprayed by the nozzle through the guide plate 34, change the coverage range and spraying angle of the paint, and ensure the uniformity of the paint spraying distribution within a certain range.

[0027] Among them, when the limit nut 35 is rotated towards one side of the fixed seat 32, the guide plate 34 gradually moves towards the fixed seat 32, so as to gradually increase the space for the paint to flow and gradually reduce the spraying range of the paint. When the limit nut 35 is rotated towards the other side of the fixed seat 32, the guide plate 34 gradually moves away from the fixed seat 32, so as to gradually reduce the space for the paint to flow, and guide the paint sprayed by the nozzle through the guide plate 34, gradually change the coverage range and spraying angle of the paint, and gradually increase the spraying range of the paint.

[0028] In the present utility model, by rotating the limit nut 35, the guide plate 34 rotates under the action of the fixed shaft, so as to guide the paint sprayed by the nozzle through the guide plate 34, change the coverage range and spraying angle of the paint, and ensure the uniformity of the paint spraying distribution within a certain range.
