[0020] 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. Embodiment

[0021] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: A guide positioning bracket for highway marking construction, including a handheld spraying assembly 1, a positioning bracket assembly 2, and a guide wheel assembly 3. The handheld spraying assembly 1 includes a connecting rod 101, a nozzle 102, a positioning ring 103, and a handle 104. The nozzle 102 is fixedly installed at the lower end of the connecting rod 101. The positioning ring 103 is sleeved on the outer surface of the lower end of the connecting rod 101. The handle 104 is sleeved on the outer surface of the upper end of the connecting rod 101. The positioning bracket assembly 2 includes a steering connection block 201, a pressure plate 202, and a scale cross bar 203. A connection slot hole 204 is opened in the middle of the steering connection block 201. The positioning ring 103 is clamped in the connection slot hole 204. The pressure plate 202 is installed on the upper surface of the steering connection block 201 by a hand-tightening screw. Two scale cross bars 203 are symmetrically and fixedly installed on both sides of the steering connection block 201. The guide wheel assembly 3 includes a guide plate 301, a guide shaft 302, a roller 303, and an O-ring 304. A slide hole 305 that is in clearance fit with the scale cross bar 203 is opened above the guide plate 301. A socket head cap bolt 306 for pressing the scale cross bar 203 is threadedly connected to the upper end of the guide plate 301. The guide shaft 302 is fixedly installed on one side below the guide plate 301 by a screw. A deep groove ball bearing 307 is provided between the guide shaft 302 and the roller 303.

[0022] Specifically, the connecting rod 101 is a hollow tube. A feeding hose is connected above the nozzle 102. The feeding hose passes through the upper end of the connecting rod 101 and is connected to the cold spray marking machine. When the cold spray marking machine works, it provides high-pressure paint for the nozzle 102. The handheld spraying assembly 1 can be connected to the positioning bracket assembly 2 through the positioning ring 103, and then pushed on the ground by the support of the guide wheel assembly 3. At this time, changing the installation height of the positioning ring 103 can change the distance between the nozzle 102 and the ground. The farther the distance between the nozzle 102 and the ground, the larger the spraying range. On the contrary, the closer the distance between the nozzle 102 and the ground, the smaller the spraying range. Rotating the handheld spraying assembly 1 can change the spraying angle of the nozzle 102. Swinging the handheld spraying assembly 1 back and forth can change the tilting angle of the nozzle 102. The handheld spraying assembly 1 can also be used alone without being connected to the positioning bracket assembly 2. At this time, the usage method of the handheld spraying assembly 1 is the same as that of the traditional handheld spraying.

[0023] Please refer to Figure 6 , the positioning ring 103 is in clearance fit with the connecting rod 101. A notch is provided on one side of the positioning ring 103, and a countersunk screw is arranged in the middle of the notch. Tightening the countersunk screw can make the positioning ring 103 hold the connecting rod 101 tightly.

[0024] Specifically, the material of the positioning ring 103 is preferably aluminum alloy with low hardness, which is convenient for plastic deformation to occur on both sides of the notch under the axial tension of the countersunk screw to realize holding the connecting rod 101 tightly. The whole countersunk screw is hidden in the positioning ring 103, so that the positioning ring 103 can be smoothly inserted into the connecting slot hole 204.

[0025] Please refer to Figure 3 , the handle 104 includes a collar in clearance fit with the connecting rod 101 and a handle with rubber coating on the surface. A wing bolt is arranged on one side of the collar. Tightening the wing bolt can fix the handle 104 to the connecting rod 101.

[0026] Specifically, after loosening the wing bolt, the handle 104 can slide and rotate on the outer surface of the connecting rod 101 to adapt to workers of different heights and different working scenarios.

[0027] Please refer to Figure 2 and Figure 6 , the connecting slot hole 204 is a stepped slot hole with a broken edge in the front. The width of the broken edge slot is the same as the diameter of the connecting rod 101. The inner diameter of the upper slot is the same as the diameter of the positioning ring 103 and the depth is the same as the thickness of the positioning ring 103.

[0028] Specifically, the width of the broken-edge groove is the same as the diameter of the connecting rod 101, so that the connecting rod 101 can be directly pushed into the connecting slot hole 204 from the side. The inner diameter of the upper slot hole is the same as the diameter of the positioning ring 103, so that the positioning ring 103 can rotate within the connecting slot hole 204. The depth of the upper slot hole is the same as the thickness of the positioning ring 103, so that after the fixing pressing plate 202 is fixed above the steering connecting block 201, the positioning ring 103 can only rotate within the connecting slot hole 204 and cannot move up and down.

[0029] Please refer to Figure 1 , the scale cross bar 203 is a vertically arranged flat long plate, and the upper surfaces of the two scale cross bars 203 are provided with scales that are symmetrically arranged at the same intervals.

[0030] Specifically, the scale cross bar 203 in the shape of a flat long plate can ensure its strength and will not block too much of the staff's vision, enabling the staff to better observe the position of the roller 303 and the spraying effect. The function of the scale is to facilitate the adjustment of the symmetry of the two guiding wheel assemblies 3.

[0031] Please refer to Figure 5 , the roller 303 includes a wheel body with a thin thickness dimension and a bearing seat connected to the guiding shaft 302 on the outside. A semi-circular groove is formed on the outer circumferential surface of the wheel body, and the O-ring 304 is clamped in the semi-circular groove.

[0032] Specifically, the thin thickness dimension of the wheel body can reduce the blocked vision of the staff, and it is light and convenient for operation and carrying. The material of the O-ring 304 is rubber that is wear-resistant and has a certain elasticity. The diameter of the O-ring 304 is smaller than the outer diameter of the wheel body, and the wire diameter is the same as that of the semi-circular groove. After stretching the O-ring 304 to become larger, it is sleeved in the semi-circular groove, and the O-ring 304 tightly holds the wheel body through elastic force.

[0033] In use, first adjust the distance between the two rollers 303 according to the width of the line to be drawn on the road. For example, if a 20-cm-wide line needs to be drawn, then the distance between the two rollers 303 is adjusted to 20 cm. When adjusting, use the scale on the scale crossbar 203 as a reference to ensure that the two rollers 303 are symmetric with the steering connection block 201. Further, connect the handheld spraying assembly 1 to the positioning bracket assembly 2 through the positioning ring 103. The specific operation is to first remove the pressure plate 202, then push the connecting rod 101 located below the positioning ring 103 into the connecting slot hole 204 from the broken-edge groove of the connecting slot hole 204, and then insert the connecting rod 101 downward so that the positioning ring 103 is inserted into the connecting slot hole 204. Then use a hand-tightening screw to re-fix the pressure plate 202 to the upper surface of the steering connection block 201. At this time, the positioning ring 103 can rotate in the connecting slot hole 204 but cannot move up and down. Further, rotate the handheld spraying assembly 1 so that the countersunk head screw for locking the positioning ring 103 turns to the break of the connecting slot hole 204 and loosen the countersunk head screw. At this time, the connecting rod 101 can slide up and down in the positioning ring 103. By sliding the connecting rod 101 up and down, change the height of the nozzle 102 from the ground to change the width of the spray painting of the nozzle 102 on the ground. It is required that the width of the spray painting is 1 cm greater than the distance between the rollers 303. For example, if the distance between the rollers 303 is 20 cm, then the width of the spray painting is 21 cm. However, due to the blockage of the rollers 303, the actual width of the spray painting on the ground is also 20 cm. At this time, it exceeds 0.5 cm on one side. The exceeding part will hit the inner side of the roller 303, and some spray liquid will stick to the roller 303, but most of it will bounce down to the ground. At this time, the edge of the drawn line will be very clear. After adjusting the distance between the rollers 303 and the height of the nozzle 102, the staff pushes the guiding and positioning bracket to walk on the ground through the handle 104, and sprays a line with the same distance as the distance between the two rollers 303 between the two rollers 303. At this time, the staff can easily spray the required line with the landing point of the roller 303 as the guide. Because it is a pushing spray painting, the labor intensity of the staff can be greatly reduced, and the thickness of the spray painting line will not be inconsistent due to the shaking of the staff's hand or visual error. Since the guiding and positioning bracket is small and compact, it is light and easy to operate and does not occupy space. Furthermore, it can be operated in a narrow place. If the operating place is really narrow, the handheld spraying assembly 1 can also be removed from the positioning bracket assembly 2 and used alone, which is very flexible.

[0034] In summary, since the positioning bracket assembly 2 and the guide wheel assembly 3 of the highway marking construction guiding and positioning bracket are simple and compact in structure, they are not only convenient to carry but also easy to operate, and can thus move in a narrow space. At the same time, due to the detachable design of the hand-held spraying assembly 1 and the positioning bracket assembly 2, the spraying work becomes more flexible. Through the clamping of the positioning bracket assembly 2 and the support of the guide wheel assembly 3, the hand-held spraying assembly 1 can be pushed and pulled on the ground to move forward, which can not only reduce the labor intensity of workers but also prevent any shaking, thus achieving the effect of reducing the labor intensity of workers and ensuring uniform spraying.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
