Description

Technical Field

[0001] The utility model relates to the technical field of marking spraying, in particular to a ground marking spraying device. Background Art

[0002] Grounding mark spraying devices are widely used in construction, electricity and other fields. They are mainly used to spray eye-catching grounding marks on grounding equipment or components to improve safety and recognition. The currently commonly used spraying device is to fit the hollow font plate to the position where spraying is required, and then spray it through a spray bottle.

[0003] However, in conventional spraying equipment, most hollow lettering plates are made of hard plate material. This creates gaps when encountering curved equipment or components, preventing adhesion. This, in turn, causes excess paint to enter through the gaps during spraying, resulting in poor spraying results. Furthermore, the hard hollow lettering plates are prone to misalignment, resulting in an unsightly final spraying effect. Therefore, those skilled in the art have provided a ground marker spraying device to address the problems raised in the aforementioned background art. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the utility model provides a grounding mark spraying device to solve the problem that in traditional spraying equipment, most hollow font plates are made of hard plate materials, which will produce gaps when encountering equipment or components with curved surfaces and cannot fit, thereby causing excess paint to enter through the gaps during spraying, resulting in poor spraying effect, and the hard hollow font plates are prone to offset, resulting in an unsightly final spraying effect.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a ground mark spraying device, comprising a spray gun body and a support plate, wherein the spray gun body includes a spray head, a through slot is opened in the middle of the support plate, and bolts are threadedly connected to the upper and lower sides of the through slot, and one end of the bolt is rotatably engaged with a pressure plate, and the pressure plate is in pressure contact with the spray head. The spray head of the spray gun body is inserted into the through slot, and then the bolt is rotated to cause the pressure plate to squeeze and fix the upper and lower sides of the spray head, thereby fixing the support plate at the spray head;

[0008] Through holes are vertically opened at both ends of the support plate, and placement grooves are opened at the upper and lower ends of the through hole. A positioning rod is rotatably inserted in the through hole, and connecting plates are installed at both ends of the positioning rod. A coil spring is provided on the inner side of the connecting plate. A fixed shaft is installed at the other end of the connecting plate, and a roller is sleeved on the circumference of the fixed shaft. A hollow plate is provided on one side of the roller, and clips are installed at both ends of the hollow plate. A support rod is horizontally inserted in the middle of the connecting plate, and springs are sleeved at both ends of the support rod.

[0009] Preferably, the hollow plate is made of a flexible material and can be bent, and the hollow plate is squeezed into contact with the curved surface of the equipment or component that needs to be sprayed with the mark. When the hollow plate contacts the surface of the equipment or component, the flexible hollow plate fits the curved surface of the equipment or component.

[0010] Preferably, slide grooves are provided on both sides of the support plate, and the hollow plate is vertically plugged into the slide grooves through a clamping strip. The inner side of the hollow plate contacts the support rod and the roller in turn, and in the process of the hollow plate fitting the curved surface, the roller presses the two ends of the hollow plate.

[0011] Preferably, one end of the spring is in pressure contact with the connecting plate, and the other end of the spring is in pressure contact with the bend of the support rod. When the side of the hollow plate at the support rod squeezes the support rod, the support rod is still squeezed toward the inner side of the connecting plate under the support of the spring, thereby giving sufficient compensation to the hollow plate and preventing the hollow plate from being unable to fit.

[0012] Preferably, the inner layer of the coil spring is fixedly connected to the end of the positioning rod, and the outer layer of the coil spring is fixedly connected to the inner wall of the placement groove, so that the positioning rod has the characteristic of rotating outward and rebounding.

[0025] See also Figure 3 、 Figure 4 、 Figure 5, through holes 6 are vertically opened at both ends of the support plate 2, and mounting grooves 601 are opened at the upper and lower ends of the through hole 6. A positioning rod 8 is rotatably inserted in the through hole 6, and a connecting plate 10 is installed at both ends of the positioning rod 8. A coil spring 9 is provided on the inner side of the connecting plate 10, and a fixed shaft 1001 is installed at the other end of the connecting plate 10. A roller 11 is sleeved on the circumference of the fixed shaft 1001, and a hollow plate 14 is provided on one side of the roller 11. A card strip 15 is installed at both ends of the hollow plate 14, and a support rod 12 is horizontally inserted in the middle of the connecting plate 10, and a spring 13 is sleeved at both ends of the support rod 12. The hollow plate 14 is made of flexible material and can be bent. The hollow plate 14 is squeezed into contact with the curved surface of the equipment or component that needs to be sprayed with the mark. When the hollow plate 14 contacts the surface of the equipment or component, the flexible hollow plate 14 fits the curved surface of the equipment or component.

[0026] See also Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 When the cam 14 is in the process of being fitted with the curved surface, the roller 11 presses the two ends of the hollow plate 14, and one end of the spring 13 is pressed against the connecting plate 10, and the other end of the spring 13 is pressed against the bent part of the support rod 12. When the side of the hollow plate 14 at the support rod 12 squeezes the support rod 12, the support rod 12 is still squeezed toward the inner side of the connecting plate 10 under the support of the spring 13, thereby giving the hollow plate 14 sufficient compensation and preventing the hollow plate 14 from being unable to fit. The inner layer of the coil spring 9 is fixedly connected to the end of the positioning rod 8, and the outer layer of the coil spring 9 is fixedly connected to the inner wall of the placement groove 601, so that the positioning rod 8 has the characteristic of rotating outward and rebounding.

[0027] The ground mark spraying device in this utility model is composed of a spray gun body 1, a support plate 2 and a hollow plate 14, wherein the hollow plate 14 is made of a flexible material and can be bent;

[0028] A through slot 3 is provided in the middle of the support plate 2. Bolts 4 are threadedly sleeved on the upper and lower sides of the through slot 3. The opposite ends of the two bolts 4 are rotated and clamped with a pressure plate 5. The nozzle 101 of the spray gun body 1 is inserted into the through slot 3. Then, the bolts 4 are rotated to make the pressure plate 5 squeeze and fix the upper and lower sides of the nozzle 101, thereby fixing the support plate 2 to the nozzle 101.

[0029] Through holes 6 are vertically opened on both sides of the support plate 2, and placement grooves 601 are opened at the upper and lower ends of the through hole 6. A positioning rod 8 is rotatably inserted in the through hole 6, and two ends of the positioning rod 8 are installed with coil springs 9. After the positioning rod 8 is inserted into the through hole 6, the coil spring 9 is in the placement groove 601, and the outer layer of the coil spring 9 is connected to the inner wall of the placement groove 601, so that the positioning rod 8 has the characteristic of rotating and rebounding outward. A connecting plate 10 is installed at the two ends of the positioning rod 8, and a fixed shaft 1001 is installed at the other end of the connecting rod. A roller 11 is sleeved on the circumference of the fixed shaft 1001, and a support rod 12 is further inserted in the middle of the positioning rod 8. The horizontal parts of the upper and lower ends of the support rod 12 are sleeved with springs 13, and one end of the spring 13 is in pressure contact with the connecting plate 10;

[0030] The two ends of the hollow plate 14 are equipped with clips 15, and the hollow plate 14 is slidably connected with the slide grooves 7 on both sides of the support plate 2 through the clips 15. Since the hollow plate 14 is made of flexible material, the hollow plate 14 contacts the support rod 12 and the outer wall of the roller 11 in turn. When the spray gun body 1 and the support plate 2 are installed, the hollow plate 14 is squeezed into contact with the curved surface of the equipment or component that needs to be sprayed. When the hollow plate 14 contacts the surface of the equipment or component, the flexible The hollow plate 14 is fitted with the curved surface of the equipment or component, and in the process of fitting the hollow plate 14 with the curved surface, the roller 11 presses the two ends of the hollow plate 14. When the hollow plate 14 is deformed during fitting, the side of the hollow plate 14 at the support rod 12 squeezes the support rod 12, so that the support rod 12 is still squeezed toward the inner side of the connecting plate 10 under the support of the spring 13, thereby giving the hollow plate 14 sufficient compensation to avoid the hollow plate 14 from failing to fit;

[0031] In the spraying equipment, the font plate and the spray gun are combined, so that when the spray gun body 1 is spraying the hollow plate 14, there is no need to separately support and fix the hollow plate 14, thereby avoiding deviation and resulting in an unsightly final spraying effect. In addition, the flexible hollow plate 14 cooperates with the compensation assembly composed of the support rod 12 and the roller 11, which can perfectly fit with the curved surface of the equipment or component when spraying, avoiding the generation of gaps, resulting in excess paint entering through the gaps during spraying, resulting in poor spraying effect.
