[0027] An auxiliary device for a road marking machine, such as Figure 1 and Figure 2 As shown, including:

[0028] The main body 10 forms a U-shaped frame structure, and rollers are rotatably connected to both sides of the main body 10;

[0029] The limiting rod 11 is fixedly arranged at the bottom of the main body 10 for support, and a rack 12 is fixedly arranged on one side of the limiting rod 11. Specifically, a hole for connecting a vehicle is opened on the top surface of the main body 10, and the main body 10 can be towed by the vehicle. The limiting rod 11 is arranged on the top surface of the abdomen of the main body 10 for installing a nozzle, and the paint is sprayed on the ground through the nozzle to form a road sign. This is an existing well-known technology and will not be described in detail here;

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the mounting structure is movably arranged on the limiting rod 11 and can slide along the limiting rod 11 to adjust the position. The mounting structure includes a sliding sleeve 20, a locking plate 21 and a pressing portion 22. The locking plate 21 is fixedly connected to the pressing portion 22. The pressing portion 22 is elastically connected to the sliding sleeve 20. A window is opened on the wall of the sliding sleeve 20. The locking plate 21 can pass through the window and engage with the rack 12. The sliding sleeve 20 is slidably connected to the limiting rod 11. The limiting rod 11 forms a rectangular rod body structure. Both ends are fixed with vertical rods, which are fixedly connected to the bottom of the main body 10. The sliding sleeve 20 forms a frame structure with a U-shaped cross section. The sliding sleeve 20 is adapted to the limiting rod 11. The inner wall of the sliding sleeve 20 is slidably connected to the limiting rod 11. The sliding sleeve 20 is provided with a window on the wall of the rack 12. The size of the window is larger than the size of the locking plate 21. The wall of the locking plate 21 close to the rack 12 is provided with an integrally formed triangular prism-shaped convex rib. The convex rib of the locking plate 21 is engaged with the rack 12, and the pressing portion 22 forms The rod body structure has a Z-shaped cross section, and the pressing portion 22 is fixedly connected to the wall surface of the sliding sleeve 20 and the locking plate 21, and the pressing portion 22 extends toward one side of the locking plate 21 and forms a gap with the sliding sleeve 20, and the gap is used to avoid the flipping movement of the pressing portion 22 to avoid motion interference. The sliding sleeve 20 slides along the limiting rod 11 to adjust the position of the sliding sleeve 20. A plurality of identical sliding sleeves 20 can be slidably arranged on the limiting rod 11 and then a plurality of nozzles can be installed. The interval at which the nozzles spray road signs is adjusted by adjusting the spacing of the sliding sleeves 20. When adjusting the position of the sliding sleeve 20, the pressing portion 22 is pressed, and the pressing portion 22 drives the locking plate 21 away from the sliding sleeve 20. When the sliding sleeve 20 reaches the predetermined position, the pressing portion 22 is released. Since the pressing portion 22 is elastically connected to the sliding sleeve 20, the pressing portion 22 can drive the locking plate 21 to reset and engage with the rack 12, thereby locking the position of the sliding sleeve 20. The sliding sleeve 20 has the characteristics of flexible and convenient adjustment of the position, which is beneficial to actual operation and use.

[0031] like Figure 4 and Figure 5 As shown, the mounting structure also includes a connecting rod 24 and a spring. The connecting rod 24 is fixedly connected to the sliding sleeve 20, the pressing portion 22 is rotatably connected to the connecting rod 24, and the spring is fixedly connected to the pressing portion 22. The spring is close to the end of the pressing portion 22 away from the locking plate 21. By pushing the pressing portion 22, the connection position of the pressing portion 22 and the connecting rod 24 is close to the locking plate 21. Under the action of the lever, the pressing portion 22 will drive the locking plate 21 to flip and then separate from the rack 12. At this time, the sliding sleeve 20 can slide freely, and the pressing portion 22 will compress the spring when flipping. When the sliding sleeve 20 stops sliding, the pressing portion 22 is released, and the spring pushes the pressing portion 22 to flip and reset, and then the locking plate 21 is engaged with the rack 12 again to achieve the positioning of the sliding sleeve 20, simplifying the steps of locking the sliding sleeve 20, and making the adjustment simple and fast and efficient in locking the sliding sleeve 20.

[0032] like Figure 5As shown, a side plate 23 is fixedly mounted on one side of the sliding sleeve 20, a mounting hole is opened on the wall of the side plate 23, the nozzle is fixed and locked by screws and threaded connection with the mounting hole, and the side plate 23 extending toward one side of the sliding sleeve 20 provides support for the nozzle.

[0033] The working principle of the utility model is as follows: the pressing part 22 is pushed, and the connection position between the pressing part 22 and the connecting rod 24 is close to the locking plate 21. Under the action of the lever, the pressing part 22 will drive the locking plate 21 to flip and then separate from the rack 12. At this time, the sliding sleeve 20 can slide freely, and the sliding sleeve 20 slides along the limiting rod 11. The pressing part 22 will compress the spring when flipping. When the sliding sleeve 20 stops sliding, the pressing part 22 is released, and the spring pushes the pressing part 22 to flip and reset, and then the locking plate 21 is again engaged with the rack 12 to achieve the positioning of the sliding sleeve 20. To adjust the position of the sliding sleeve 20, a number of identical sliding sleeves 20 can be slidably arranged on the limiting rod 11 to install a plurality of nozzles. The interval between the nozzles spraying road signs is adjusted by adjusting the spacing between the sliding sleeves 20. The nozzle is fixed and locked by threaded connection with the mounting hole through a screw, and the nozzle is supported by the side plate 23 extending toward one side of the sliding sleeve 20 to achieve the installation and fixation of the nozzle.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
