Abstract
Description
Technical Field
[0001] This utility model relates to the field of zebra crossing construction, and more specifically, to a zebra crossing marking device for coating. Background Technology
[0002] In the construction and maintenance of road traffic facilities, the coating of zebra crossings is an important task. Before the coating of zebra crossings, it is usually necessary to use a line marking device to set the indicator lines in order to accurately determine the position and boundary of the zebra crossing. At present, the common way to set the indicator lines is to use a cotton rope to attach powder, such as titanium dioxide, and then use a snap-line operation to snap the powder attached to the cotton rope onto the ground, thereby forming a clear indicator line, which provides accurate positioning for the subsequent coating of zebra crossings.
[0003] However, existing line marking devices have significant drawbacks in practical use. During device transport, due to the lack of an effective sealing structure, powder easily leaks from the outlet. This not only wastes powder resources and increases construction costs, but the leaked powder may also contaminate other construction tools. Therefore, we have made improvements and proposed a zebra crossing coating line marking device. Utility Model Content

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0029] For an example, please refer to... Figures 1-7 A zebra stripe marking device includes a box body 1. A partition 101 is fixedly installed inside the box body 1, dividing the box body 1 into a powder storage chamber 103 and a winding chamber 102. The powder storage chamber 103 is used to store powder, such as titanium dioxide. A threaded hole is provided on the side of the box body 1, and a second external threaded tube 108 is threadedly connected to the inner wall of the threaded hole. One end of the second external threaded tube 108 is fixedly connected to a first hollow hexagonal plate 104 located outside the box body 1. The end of the first hollow hexagonal plate 104 away from the second external threaded tube 108 is fixedly connected to a first external threaded tube 105. A winding section is provided on the box body 1 at the winding chamber 102. A hollow cotton rope 2 is wound on the winding section. One end of the hollow cotton rope 2 passes through the second external threaded tube 108, the first hollow hexagonal plate 104, and the first external threaded tube 105. The hollow cotton rope 2 extends to the outside of the box body 1, and a second hollow hexagonal plate 106 located outside the box body 1 is fixedly connected to the outer surface of the hollow cotton rope 2. An internal threaded tube 107 is fixedly connected to the side of the second hollow hexagonal plate 106 near the first external threaded tube 105. By setting the second hollow hexagonal plate 106 and the internal threaded tube 107 on the hollow cotton rope 2, after the hollow cotton rope 2 is wound up, the internal threaded tube 107 is connected to the first external threaded tube 105 to achieve the sealing of the first external threaded tube 105, thereby preventing the powder from seeping out from the first external threaded tube 105, reducing the waste of powder resources, reducing construction costs, and reducing the amount of powder that will contaminate other construction tools by successfully preventing the powder from seeping out. This also protects other tools from contamination and reduces the maintenance and replacement costs caused by tool contamination.
[0030] Furthermore, the hollow cotton rope 2 has a knot 201 at one end outside the box body 1. The knot 201 is designed to provide a gripping point for the user's hand, making it easy for the user to pull.
[0031] Furthermore, a threaded hole is also provided on the partition 101, and a third external threaded tube is threadedly connected to the threaded hole. One end of the third external threaded tube is fixedly connected to a third hollow hexagonal plate 109. The hollow cotton rope 2 passes through the third external threaded tube and the third hollow hexagonal plate 109. By rotating the third hollow hexagonal plate 109, the third external threaded tube can be separated from the threaded hole on the partition 101, and the third hollow hexagonal plate 109 and the third external threaded tube can be removed and replaced.
[0032] Furthermore, the winding section includes two bearings 5 mounted on the housing 1, with a winding spool 501 inserted between the two bearings 5. The end of the hollow cotton rope 2 away from the knot 201 is tied to the outer surface of the winding spool 501, and the hollow cotton rope 2 is wound around the winding spool 501. The hollow cotton rope 2 can be wound up by rotating the winding spool 501.
[0033] Furthermore, a handwheel 504 is fixedly connected to one end of the winding spool 501. The end of the winding spool 501 away from the handwheel 504 is a threaded end, and a limit nut 502 is threadedly connected to the threaded end of the winding spool 501. A retaining ring 503 is fixedly connected to the outer surface of the end of the winding spool 501 near the handwheel 504. The retaining ring 503 and the limit nut 502 respectively contact the opposite sides of the two bearings 5. The handwheel 504 facilitates the rotation of the winding spool 501. The winding spool 501 can be limited between the two bearings 5 through the cooperation of the limit nut 502 and the retaining ring 503.
[0034] Furthermore, a first cover plate 110 is installed on the top of the box body 1 via a hinge, located above the powder storage chamber 103. A buckle 112 is provided between the first cover plate 110 and the box body 1. The first cover plate 110 can protect the area on the top of the box body 1 corresponding to the powder storage chamber 103, reducing the exposure of powder.
[0035] Furthermore, a second cover plate 111 is installed on the top of the box body 1 via a hinge, located above the winding chamber 102. A buckle 112 is also provided between the second cover plate 111 and the box body 1. The second cover plate 111 can protect the area on the top of the box body 1 corresponding to the winding chamber 102.
[0036] Furthermore, an auxiliary component is provided at one end of the box body 1 near the first hollow hexagonal plate 104. The auxiliary component includes a powder receiving box 3. The powder receiving box 3 is located at one end of the box body 1 near the first hollow hexagonal plate 104 and is located below the first hollow hexagonal plate 104. During the process of the hollow cotton rope 2 being pulled outward, the powder receiving box 3 can collect the powder that is carried out and spilled by the hollow cotton rope 2.
[0037] Furthermore, the powder receiving box 3 is provided with a fixing bolt 301, and the box body 1 is provided with a threaded groove 4. The fixing bolt 301 is threadedly connected to the inner wall of the threaded groove 4. The fixing bolt 301 and the threaded groove 4 cooperate with each other to achieve a detachable connection between the powder receiving box 3 and the box body 1. After rotating the fixing bolt 301, the powder receiving box 3 can be removed and the powder can be poured back into the powder storage chamber 103 for reuse.
[0038] Furthermore, the first hollow hexagonal plate 104, the first externally threaded tube 105, and the second externally threaded tube 108 are integrally formed; the second hollow hexagonal plate 106 and the internally threaded tube 107 are integrally formed; and the third hollow hexagonal plate 109 and the third externally threaded tube are integrally formed. All of the above components are made of Teflon material. Teflon material has low friction characteristics, which can reduce the wear of the hollow cotton rope 2. After the hollow cotton rope 2 passes through the second hollow hexagonal plate 106, sealant, such as epoxy resin, is applied between the hollow cotton rope 2 and the second hollow hexagonal plate 106. This not only fixes the second hollow hexagonal plate 106 and the hollow cotton rope 2, but also seals the connection between the hollow cotton rope 2 and the second hollow hexagonal plate 106.
[0039] The partition 101 is welded inside the housing 1. The bearing 5 is installed by making a hole in the housing 1, inserting the bearing 5 into the hole, and then welding the outer ring of the bearing 5 to the housing 1. The retaining ring 503 and the handwheel 504 are both connected to the winding shaft 501 by welding.
[0040] The latch 112 is a commonly used locking component. Its specific structure and usage are existing technologies, and will not be described in detail in this application.
[0041] In use, rotate the second hollow hexagonal plate 106 to separate the internally threaded tube 107 from the first externally threaded tube 105, and then pull the knot 201 outward. The knot 201 drives the hollow cotton rope 2 to move outward. When the hollow cotton rope 2 passes through the powder storage chamber 103, the powder adheres to the hollow cotton rope 2. Two workers work together to place the hollow cotton rope 2 on the road surface where zebra crossings need to be coated, and then perform an elastic operation to make the powder on the hollow cotton rope 2 bounce onto the ground.
[0042] After use, turn the handwheel 504 to drive the winding shaft 501 to rotate, so that the winding shaft 501 can wind up the hollow cotton rope 2 and return the hollow cotton rope 2 back into the box 1. Finally, screw the inner thread tube 107 onto the outer surface of the first outer thread tube 105.
