DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1

[0027] In one embodiment, Figure 1-Figure 7 As shown, a detachable nozzle of a road marking machine includes a connecting pipe 100, a connecting assembly 200 and a nozzle assembly 300. The connecting pipe 100 is threadedly connected with the connecting assembly 200 below, and the nozzle assembly 300 is plugged into the connecting assembly 200. The connecting pipe 100 is connected to the connecting device 200 through a thread 104. The connecting device 200 can be removed by holding both ends of the nozzle 300 and rotating downward, thereby completing the disassembly and replacement of the nozzle conveniently and quickly.

[0028] In one embodiment, Figure 1-Figure 3 As shown, the connecting pipe 100 includes a pipe body 101, an air inlet 102, a paint inlet 103, a thread 104 and a pipe mouth 105. The top of the pipe body 101 is connected to the bottom of the road marking machine. The air inlet 102 and the paint inlet 103 are arranged on the left side of the pipe body 101. The bottom surface of the pipe body 101 is also provided with a thread 104. The pipe mouth is arranged at the bottom of the pipe body. During use, gas and paint enter the pipe body 101 through the air inlet 102 and the paint inlet 103 respectively, and then enter the connecting assembly 200 through the pipe mouth 105.

[0029] In one embodiment, Figure 4-Figure 7As shown, the connection assembly 200 includes a connection body 201, a thread groove 202, a through hole 204, a nozzle 205, a fastening assembly 206 and a reaming hole 207. The connection body 201 is provided with a thread groove 202 on the top, and a fastening assembly 206 is provided on the right side of the connection body 201. The through hole 204 runs through the left and right sides of the connection body, and the through hole 204 matches the nozzle assembly 300. The nozzle 205 runs through the upper and lower ends of the connection body 201, and the center of the bottom of the connection body 201 is provided with a reaming hole 207. The nozzle assembly 300 includes a nozzle 1 301, a nozzle 2 302, and a nozzle 3 303, a slider 307 and a protective cover 308, the spray hole 1 301, the spray hole 2 302 and the spray hole 3 303 are arranged on the slider 307 in sequence at the same interval, and protective covers 308 are provided at both ends of the slider 307. The fastening assembly 206 includes a fastening screw 208 and a fastening plate 209, and the fastening screw 208 is threadedly connected to the fastening plate 209. The nozzle assembly 300 is pushed left and right by pressing the protective cover 308 to switch different spray holes. After the switching is completed, the fastening screw 208 is rotated downward to fix the nozzle assembly 300 to prevent the nozzle assembly 300 from sliding left and right, so as to adapt to different construction environments;

[0030] In one embodiment, Figure 5 As shown, the spray hole 1 301, spray hole 2 302 and spray hole 303 are respectively provided with a hole plate 1 304, a hole plate 2 305 and a hole plate 3 306 of corresponding sizes. After the paint enters the spray hole, it is evenly sprayed on the road surface under the action of the hole plate, thereby improving the construction quality.

[0031] Example 2

[0032] In one embodiment, Figure 4 As shown, a sealing ring is provided at the bottom of the threaded groove 202 at the top of the connection component 200, which can effectively prevent gas and paint from leaking when the paint and gas enter the connection component 200 through the connection pipe 100, save resources, and improve construction quality.

[0033] The above example discloses a detachable nozzle for a road marking machine. When in use, the road marking machine is pushed on the construction road surface by the handle, and the engine drives the air compressor and the barrel to transport gas and paint to the connecting pipe 100 through the air pipe and the material pipe. The paint is sprayed out from the nozzle 205 under the action of the air pressure to complete the line drawing work. When it is necessary to disassemble and replace the nozzle, the two ends of the nozzle 300 can be held and rotated downward to remove the connecting device 200 together with the nozzle assembly 300. In addition, when it is necessary to use spray holes of different sizes, the nozzle assembly 300 can be switched by pressing the protective cover 308 to push the nozzle assembly 300 left and right. After the switching is completed, the fastening screw 208 is rotated downward to fix the nozzle assembly 300 to prevent the nozzle assembly 300 from sliding left and right, so as to adapt to different construction environments.

[0034] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
