DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] See also Figure 1-3A road marking device for urban road traffic includes a base plate 1, and the four corners of the bottom of the base plate 1 are fixedly connected to universal wheels 2. The arrangement of the universal wheels 2 facilitates the movement of the entire device. A storage mechanism 3 is connected to the top of the base plate 1. The storage mechanism 3 includes a storage barrel 32 that is detachably connected to the top of the base plate 1. The interior of the storage barrel 32 can hold paint required for marking. A limit ring 31 is fixedly connected to the top of the base plate 1. The storage barrel 32 is inserted into the interior of the limit ring 31. The circumference of the limit ring 31 is threadedly connected with a plurality of limit bolts 34 in an annular array. Each group of limit bolts 34 abuts against the outer wall of the storage barrel 32. The limit bolts 34 can play a role in limiting and fixing the storage barrel 32, so as to facilitate the subsequent disassembly and replacement of the storage barrel 32 containing paints of different colors.

[0021] A pump 5 fixedly connected to the bottom plate 1 is provided on one side of the material storage mechanism 3. A first hose 4 is fixedly connected to the input end of the pump 5. The first hose 4 extends to the inner bottom of the material storage barrel 32. When the pump 5 is started, the paint inside the material storage mechanism 3 can be extracted through the first hose 4. A top cover 33 adapted to the material storage barrel 32 is fixedly connected to the outside of the first hose 4. The top cover 33 can cover the top of the material storage barrel 32 to reduce the probability of dust and debris falling into the material storage barrel 32. A U-shaped handle 35 is symmetrically fixedly connected to the top of the top cover 33. The U-shaped handle 35 can be easily taken and placed.

[0022] The output end of the pump 5 is fixedly connected to a connecting pipe 6, and one side of the connecting pipe 6 is evenly fixedly connected to a second hose 8, which can guide the paint extracted by the pump 5. A valve 7 is fixedly connected between each group of second hoses 8 and the connecting pipe 6, and the valve 7 can control whether the paint inside the connecting pipe 6 flows into the second hose 8. The second hose 8 is fixedly connected to a nozzle 13 on one side away from the connecting pipe 6, and the nozzle 13 can spray the paint discharged from the second hose 8 on the road surface to achieve road marking construction.

[0023] The outer side of each group of nozzles 13 is fixedly connected with a hollow slider 10, and one side of the bottom plate 1 is fixedly connected with a fixed beam 9, and a guide hole 11 is provided inside the fixed beam 9. Each group of hollow sliders 10 is sleeved on the outer side of the fixed beam 9, and the fixed beam 9 can guide the sliding of the hollow slider 10, so as to adjust the position of the nozzle 13. Each group of hollow sliders 10 is slidably connected with the fixed beam 9, and a rotating shaft 14 rotatably connected with the fixed beam 9 is provided inside the guide hole 11. A cam rod 12 is fixedly connected to the outer side of the rotating shaft 14, and the cam rod 12 abuts against the outer wall of each group of hollow sliders 10. When the rotating shaft 14 rotates, it can drive the cam rod 12 to rotate accordingly. When the cam rod 12 rotates to abut against each group of hollow sliders 10, it can play a role in limiting and fixing each group of hollow sliders 10.

[0024] One end of the rotating shaft 14 is fixedly connected to a connecting block 15, and an insert rod 16 is slidably connected inside the connecting block 15. A slot 19 adapted to the insert rod 16 is provided on one side wall of the fixed beam 9, and the insert rod 16 is inserted into the inside of the slot 19. After the cam rod 12 rotates to be tightly pressed against each group of hollow sliders 10, the insert rod 16 can be inserted into the inside of the slot 19, thereby achieving the function of limiting the connecting block 15 and the rotating shaft 14. A pull block 17 is fixedly connected to the end of the insert rod 16 away from the fixed beam 9, and a spring 20 is fixedly connected between the pull block 17 and the connecting block 15. Specifically, the spring 20 is in a compressed state, so that the elastic action of the spring 20 can be used to pull the pull block 17 and the insert rod 16 to move to one side of the fixed beam 9, thereby reducing the probability of the insert rod 16 being separated from the inside of the slot 19. A pull ring 18 is fixedly connected to the end of the pull block 17 away from the insert rod 16, and the setting of the pull ring 18 can facilitate the pulling and adjustment of the insert rod 16.

[0025] When in use, the insertion rod 16 is pulled out from the inside of the slot 19, and then the connecting block 15 is rotated so that the connecting block 15 drives the rotating shaft 14 and the cam rod 12 to rotate, so that the cam rod 12 is separated from the tight contact with each group of hollow sliders 10, and then the groups of hollow sliders 10 are slid as needed to adjust the distance between two adjacent nozzles 13 to the required size, and then the connecting block 15 is rotated again so that the connecting block 15 drives the rotating shaft 14 and the cam rod 12 to rotate until the cam rod 12 is rotated again to be tight against the outer wall of each group of hollow sliders 10, and at the same time, the pull block 17 and the insertion rod 16 are elastically released by the spring 20. Under the action of the force, it moves to one side of the fixed beam 9, so that the insertion rod 16 is inserted into the slot 19 again, thereby limiting the rotation of the connecting block 15, and then the valve 7 corresponding to the unused nozzle 13 is closed, and then the pump 5 can be started, so that when the pump 5 starts working, the paint inside the storage barrel 32 can be extracted into the inside of the connecting pipe 6 through the first hose 4, and then discharged into the corresponding second hose 8 and the inside of the nozzle 13 through each group of opened valves 7, and finally sprayed on the road through the corresponding nozzle 13, and at the same time, the whole device can be pushed to move, so as to realize the road marking construction.

[0026] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
