The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] See also Figures 1 to 4 The court marking device of the present invention includes at least two connected underground fixing members, wherein the underground fixing members include a telescopic rebounder 10 and a winding box 20. The winding box 20 is arranged in a pre-dug pit on the ground through the telescopic rebounder 10. The telescopic rebounder 10 can be switched between an extended and a retracted state so that the winding box 20 is hidden in the pit or exposed on the ground surface.

[0027] A side tape 30 with a male buckle 31 is wound in one of the winding boxes 20, and a side tape 30 with a female buckle (not shown) is wound in the other winding box 20. The male buckle 31 cooperates with the female buckle to connect the side tapes 30 of the two buried fixing parts into one.

[0028] By digging pits at multiple specific locations on the lawn or flat ground and installing underground fixings in the pits, when in use, two adjacent winding boxes 20 are pulled out of the pits and connected to each other's edge tapes 30, which can quickly, conveniently and non-destructively mark lines, which is conducive to carrying out various sports activities. At the same time, by changing the pulling method, rapid conversion between multiple courts can be achieved, meeting the diverse needs of venues for different time periods and different types of sports activities.

[0029] See Figure 1 In this embodiment, the wire reel box 20 is a cubic structure with a length, width and height of 6 cm. A cavity running through the front and back is provided inside the cube. The side tape 30 is wound in the cavity and can be pulled out from the front or back of the wire reel box 20 to connect with the side tape 30 of another wire reel box 20, without being limited to one side, making it more flexible and convenient to use.

[0030] Specifically, the telescopic rebounder 10 includes a fixed section 11 and a telescopic section 12 that cooperates with the fixed section 11. The telescopic section 12 is rotatably connected to the bottom of the winding box 20, so that when the winding box 20 pops out of the pit, it can rotate 360° and connect to the winding box 20 in different directions.

[0031] It should be noted that when installing the underground fixing parts in this embodiment, it is necessary to open a square pit on the ground and a cylindrical pit on the bottom of the square pit, wherein the cylindrical pit is used to install the fixing section 11 of the telescopic rebounder 10, and the square pit is used to accommodate the wire winding box 20. It should be noted that the height of the square pit should be slightly higher than the wire winding box 20 to ensure that the wire winding box 20 can be pressed and rebounded.

[0032] Furthermore, a sliding sleeve 40 is provided at the bottom of the winding box 20, which is slidably connected to the fixed section 11. This sleeve 40 not only improves the stability of the winding box 20 during its upward and downward sliding, but also protects the telescopic section 12, extending the service life of the telescopic rebounder 10. It should be noted that after adding the sleeve 40, the diameter of the cylindrical pit should be adjusted to avoid interference with the sliding of the sleeve 40.

[0033] For details, see Figure 3The inside of the winding box 20 is provided with a fixed shaft 51, a clockwork box 52 connected with the fixed shaft 51, and a shell 53 surrounding the clockwork box 52. An opening 54 is arranged on the shell 53. The edge line belt 30 is wound on the clockwork box 52. One end of the edge line belt 30 is fixed to the clockwork box 52, and the other end is connected with the male buckle 31 or the female buckle and passes through the opening 54. It can be understood that the design of the clockwork box 52 makes the winding of the edge line belt 30 more convenient. Specifically, when the edge line belt 30 needs to be wound, the connection between the male buckle 31 and the female buckle is only needed to be disconnected, and the edge line belt 30 can be automatically retracted under the action of the elastic force.

[0034] In addition, it is worth mentioning that, in actual use, when the edge line belt 30 is deformed by external force, the clockwork box 52 can also timely straighten the edge line belt 30, thereby ensuring the integrity of the field planning.

[0035] In combination with Figure 3 and Figure 4 , a slit is arranged on the fixed shaft 51. The clockwork box 52 comprises a bottom plate 521 and a surrounding plate 522 arranged on the periphery of the bottom plate 521. An axle hole 523 is arranged on the bottom plate 521 and rotationally matched with the fixed shaft 51. A clockwork spring 524 is wound in the surrounding plate 522. One end of the clockwork spring 524 is fixed to the inner wall of the surrounding plate 522, and the other end is clamped in the slit of the fixed shaft 51. Under normal circumstances, the clockwork spring 524 is in a tightened state and does not generate a pulling force on the edge line belt 30, and the edge line belt 30 can be in a normal storage state. After the edge line belt 30 is pulled out, the clockwork spring 524 is in an expanded state, and at this time, the elastic force of the clockwork spring 524 can generate a pulling force on the edge line belt 30, thereby maintaining the winding trend of the edge line belt 30.

[0036] Further, referring to Figure 1 , the top surface of the winding box 20 is provided with an LED light panel 60. The winding box 20 is more conspicuous in the night or in an environment with insufficient light. This helps people quickly identify and locate the winding box 20. In addition, when the winding box 20 is hidden in a pit, the LED light panel 60 can also serve as a ground light.

[0037] Further, a reflective sticker (not shown in the figure) is arranged on the outer side wall of the winding box 20. The reflective sticker can reflect the surrounding light, so that the winding box 20 is more prominent in vision after being pulled out, and the surrounding people are more likely to notice the existence of the winding box 20, thereby avoiding safety accidents such as collision or tripping.

[0038] The working principle of the present invention is as follows: first, press down multiple wire reel boxes 20 in a specific area, so that the wire reel boxes 20 bounce up under the action of the telescopic rebounder 10, and then, according to needs, connect the edge tapes 30 in two adjacent wire reel boxes 20 in turn through male and female buckles until the required court boundary is built. After the construction is completed, press down all the wire reel boxes 20 again to bury them back in the pit. At this time, the edge tapes 30 are in contact with the ground, completing the construction of the court boundary.

[0039] In summary, the court marking device in the above-mentioned embodiment of the present invention digs pits at multiple specific locations on the lawn or flat ground and installs underground fixings in the pits. When in use, two adjacent winding boxes 20 are pulled out of the pits and connected to each other's edge tapes 30, which can quickly, conveniently and non-destructively mark the lines, which is conducive to carrying out various sports activities. At the same time, by changing the pulling method, rapid conversion between multiple courts can be achieved, meeting the diverse needs of venues for different time periods and different types of sports activities.
