Description

Technical Field

[0001] The utility model relates to the field of road sign drawing, in particular to a road sign drawing device. Background Art

[0002] A road sign drawing device is a drawing device that sprays paint on the road to form road signs. Generally, road signs are formed by moving the device in conjunction with continuous spraying of paint. It is a commonly used device for drawing road signs. When the existing road sign drawing device is in use, the road signs are generally straight-line structures, so the device needs to move in a straight line to spray and draw the road signs. However, when the device moves, the uneven road surface will affect the accuracy of the movement, and the movement accuracy of the device itself is also poor, so the road sign drawing is not accurate enough and the operation is more troublesome. At the same time, the integrated structure of the device cannot disassemble and maintain the pump and the nozzle, and adjust the spraying angle, which is not convenient for the use of the device.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 4 As shown, a road sign drawing device includes a mounting plate 1, a supporting moving wheel 3 is movably mounted on the lower end of the mounting plate 1, a power box 6 is fixedly mounted on the upper end of the mounting plate 1, a paint storage tank 7 is fixedly mounted on the upper end of the mounting plate 1 behind the power box 6, a sealing tank cover 8 is fixedly mounted on the upper end of the paint storage tank 7, movable card slots 9 are opened on both sides of the mounting plate 1, a mounting rod 10 is movably mounted inside the mounting plate 1, two movable connecting rods 11 are movably penetrated inside the mounting rod 10, connecting bolts 12 are threadedly mounted on both ends of the movable connecting rod 11, a docking sleeve 13 is welded to the rear of the upper end of the mounting rod 10, a docking rod 14 is movably inserted into the docking sleeve 13, a spray box 15 is fixedly mounted on the rear end of the docking rod 14, a drawing nozzle 16 is fixedly mounted on the rear end of the spray box 15, a paint pumping pump 17 is fixedly mounted on the upper end of the spray box 15, and a spring connecting pipe 18 is fixedly mounted on the input port of the paint pumping pump 17.

[0020] In this embodiment, a tractor 2 is fixedly installed at the front end of the mounting plate 1, a pushing handle 4 is fixedly installed at the upper end of the mounting plate 1 in front of the power box 6, a control box 5 is fixedly installed on the inner side of the pushing handle 4, the tractor 2 is used to connect to the traction vehicle to tow and move the device, the pushing handle 4 has a pushing and pulling effect, and the control box 5 has the effect of controlling the main power switch.

[0021] In this embodiment, the mounting rod 10 extends backward to the rear of the mounting vehicle plate 1, and the spray box 15 is located behind the mounting vehicle plate 1. The mounting rod 10 slides left and right around the movable connecting rod 11. The movable connecting rod 11 passes through the movable card slot 9 and slides back and forth around it. The connecting bolts 12 at both ends of the movable connecting rod 11 are fitly connected with the two sides of the mounting vehicle plate 1. The movable connecting rod 11 has the effect of sliding and positioning the mounting rod 10 forward and backward and left and right.

[0022] In this embodiment, the docking rod 14 is arranged in an L shape, and the docking rod 14 rotates around the interior of the docking sleeve 13, so that the docking rod 14 has the effects of active connection and quick disassembly and assembly.

[0023] In this embodiment, the front end of the spring connecting tube 18 is connected to the paint storage tank 7, and the output end of the paint pump 17 is connected to the spray box 15. The spring connecting tube 18 is designed with a spring structure so that it can be stretched and maintained connected when the spray box 15 moves.

[0024] It should be noted that the utility model is a road sign drawing device. When in use, the mounting plate 1 is the main part, and the supporting and moving wheels 3 play a supporting and moving role. The paint required for road sign drawing is stored in the paint storage tank 7. When the device moves to the position where the road sign drawing is required, the paint pumping pump 17 is operated to make the paint pumping pump 17 draw the paint in the paint storage tank 7 through the spring connecting pipe 18 and transport it to the spray box 15, thereby increasing the paint pressure in the spray box 15. Then the paint is sprayed downward through the drawing nozzle 16 and sprayed on the ground to draw the road sign, and the overall movement of the device is coordinated to drive the drawing nozzle 16 to perform mobile spray drawing of the road sign.

[0025] When the drawing nozzle 16 needs to be moved for spraying and drawing, the spray box 15 can be pulled backward, thereby pulling the mounting rod 10 to move backward in the mounting vehicle plate 1, and at the same time driving the movable connecting rod 11 to slide backward around the movable card slot 9, so that when the mounting vehicle plate 1 does not move, the spray box 15 and the drawing nozzle 16 move backward to perform linear spraying and drawing, and at the same time, the mounting rod 10 can also slide left and right around the movable connecting rod 11 to perform linear spraying and drawing at multiple positions;

[0026] By utilizing the splicing structure of the docking rod 14 inserted into the docking sleeve 13, the docking rod 14 can be quickly inserted into the docking sleeve 13 for installation and pulled out for separation, and the spray box 15 and the paint pump 17 can be quickly disassembled and assembled, which is convenient for the maintenance of the paint pump 17 and the replacement of the drawing nozzle 16. At the same time, when the spray box 15 is rotated, the docking rod 14 can also be rotated around the docking sleeve 13 to drive the drawing nozzle 16 to rotate, adjust the angle of the nozzle drawing, and make it more convenient to use spray drawing at different angles.

[0027] 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. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
