Technical Field

[0001] The utility model relates to the technical field of courts, in particular to an anti-aging and detachable court. Background Art

[0002] As a common venue for sports, hard courts are the most common. During the construction of hard courts, a cement leveling layer must be laid first, and then waterproof asphalt and silicone PU rubber layers must be laid in sequence on top of the cement leveling layer. After each laying, it is necessary to re-level. Courts can be divided into indoor and outdoor types according to their location of use. They can be divided into football fields, tennis courts, badminton courts, etc. according to the usage scenarios. There are various court surfaces, usually three types: grass, hard ground and red clay.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1 - Figure 7 A detachable court resistant to aging comprises a detachable plate 1, wherein the four corners of the bottom surface of the detachable plate 1 are provided with ground plugs 2, and the four ground plugs 2 are connected with external threaded rods 3 on one side close to the detachable plate 1, and the four corners of the bottom surface of the detachable plate 1 are provided with rotation grooves 101, and the four rotation grooves 101 are penetrated with adjustment holes 102 on the side away from the ground plugs 2, and the four adjustment holes 102 are connected with limiting components, and the four rotation grooves 101 are slidably connected with internal threaded tubes 4, and the four external threaded rods 3 are respectively threadedly connected with the four internal threaded tubes 4, and the ends of the four internal threaded tubes 4 away from the external threaded rods 3 are fixedly connected with adjustment plates 5, and the four limiting components are respectively connected with the four adjustment plates 5, and the center position of the side of the adjustment plate 5 away from the internal threaded tube 4 is provided with a rotation groove 501.

[0026] like Figure 1 - Figure 7As shown, the anti-aging detachable court in the utility model is similar to the existing anti-aging detachable court structure, such as the anti-aging detachable court disclosed in the patent with publication number CN218373129U. The main improvement of the utility model is that it can make the installed court more flat as a whole, and improve the safety of the constructed court. Figures 1 to 7 As shown, when the aging-resistant detachable court of the utility model is in use, the four ground plugs 2 at the four corners of the detachable plate 1 are inserted into the installation ground, and then a tool is used to extend into the adjustment hole 102, and the adjustment plate 5 is rotated through the rotating groove 501, thereby driving the internal threaded tube 4 below to rotate, and cooperating with the external threaded rod 3 to adjust the distance between the detachable plate 1 and the ground plug 2, so that the four corners of the detachable plate 1 are consistent in height with the connection between the adjacent detachable plates 1, thereby making the entire court layout more flat, and further improving the safety of the court when in use.

[0027] like Figure 1 - Figure 7 As shown, the limiting assembly includes a sealing plate 6 and a limiting column 7. A plurality of evenly arranged limiting holes 502 are provided on the outer edge of the adjusting plate 5 away from the internal threaded tube 4. The limiting column 7 is matched with the plurality of limiting holes 502. The side of the limiting column 7 away from the adjusting plate 5 is fixedly connected to the sealing plate 6. The sealing plate 6 is matched with the adjusting hole 102 and is slidably connected to the adjusting hole 102. The sealing plate 6 is non-circular in design. After completing the height adjustment of the four corners of the removable plate 1 by rotating the internal threaded tube 4, use the sealing plate 6 to insert into the adjustment hole 102, and insert one of the multiple limiting holes 502 through the limiting column 7, so as to limit the position of the adjusting plate 5 to prevent the internal threaded tube 4 from automatically rotating when the removable plate 1 is subjected to force and presses the internal threaded tube 4 downward, causing the removable plate 1 to sink downward. The non-circular design of the sealing plate 6 can cooperate with the limiting column 7 to limit the adjusting plate 5 to prevent the adjusting plate 5 from rotating. At the same time, the sealing plate 6 can block the adjusting hole 102 to prevent dust, water stains, etc. from entering the adjusting hole 102.

[0028] like Figure 5 and Figure 7 As shown, the limiting column 7 is perpendicular to the lower surface of the sealing plate 6. The limiting column 7 and the sealing plate 6 are in a vertical state, so that the sealing plate 6 is easier to insert into the adjustment hole 102.

[0029] like Figure 1 - Figure 7 As shown, the upper surface of the sealing plate 6 is flush with the upper surface of the removable plate 1. Designing the upper surface of the sealing plate 6 to be flush with the upper surface of the removable plate 1 can enable the sealing plate 6 to form a better blocking effect on the adjustment hole 102, thereby preventing the adjustment hole 102 from affecting the use of the court.

[0030] like Figure 1 - Figure 7 As shown, an annular anti-slip groove 103 is provided at one end of the rotating groove 101 close to the adjusting hole 102, and the adjusting plate 5 is matched with the annular anti-slip groove 103 and slidably connected with the inner wall of the annular anti-slip groove 103. Through the connection and cooperation between the adjusting plate 5 and the annular anti-slip groove 103, the connection position between the internal threaded tube 4 and the detachable plate 1 can be made more stable, and the risk of falling off is not easy to occur.

[0031] like Figure 1 - Figure 7 As shown, both sides of the ground plug 2 away from the end of the external threaded rod 3 are provided with inclined surfaces. Designing the two sides of the end of the ground plug 2 inserted into the bottom surface as two inclined surfaces can make it easier to insert the ground plug 2 into the ground, and at the same time, when the internal threaded tube 4 and the external threaded rod 3 are rotated to adjust the height, the ground plug 2 is prevented from rotating with the external threaded rod 3, thereby improving the operational stability when adjusting the height of the detachable plate 1.

[0032] like Figure 1 - Figure 7 As shown, the ground plug 2 is fixedly connected to the baffle 8 on one side close to the external threaded rod 3, and the other side of the baffle 8 is fixedly connected to the external threaded rod 3, and the diameter of the baffle 8 is larger than the diameter of the external threaded rod 3. When the internal threaded tube 4 rotates on the external threaded rod 3, when the bottom of the internal threaded tube 4 contacts the baffle 8, the baffle 8 blocks the internal threaded tube 4 that rotates downward, preventing the top of the external threaded rod 3 from penetrating the adjustment plate 5, thereby improving the stability of the adjustment structure.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
