[0099] As shown in Figures 1-5 , Figures 12-16 , the tensioning lock 21 is provided with a pressing handle, the pressing handle is provided with a pull ring, the pull ring is connected with the fixed hook 22, and the front-back direction connection and positioning of the center floor module 10 and the side floor module 11 are realized; the positioning card 31 is provided with a pin column, the pin column is connected with the corner card 32, and the connection and fixing of the side floor module 11 adjacent to the left and right sides of the center floor module 10 and the connection and fixing of multiple side floor modules 11 on the right side are realized.

[0100] As shown in Figure 12 , Figure 14 , the support protrusion under the left side edge of the side floor module 11 is not recessed, the bottom surface thereof is located on the upper plane of each cross support after assembly, and abuts against the upper plane of each cross support, so that the gravity and impact force occurring on the side edge of the side floor module 11 can be quickly transmitted to each cross support, gravity support outside the tongue and groove is formed, the tongue and groove are mutually reinforced, the impact resistance and long-term deformation resistance of the left side edge of the side floor module 11 are greatly reduced, and the stability and firmness of the application under the impact of intense sports are greatly enhanced.

[0101] As shown in Figure 1 , Figure 2 , Figure 15 , the front end and the rear end of the left cross support 102 and the right cross support 103 of the center floor module 10 are provided with matching recesses and protrusions, when multiple center floor modules 10 are assembled in the front-back direction to form a single-row center floor module 10, the matching recesses and protrusions can ensure that the left and right side edges of the single-row center floor module 10 are straight, neat and consistent, serving as the assembly reference line of the side floor module 11; the matching recesses and protrusions enable the single-row floor module 10 not to be displaced due to the impact and pulling of the side floor module 11 when the side floor module 11 is assembled in the left-right direction of the single-row floor module 10, and ensure that the large-area paving of the application is carried out smoothly.

[0102] When multiple center floor modules 10 are assembled in the front-back direction, the front end recesses of the left and right cross supports of the center floor module 10 are connected with the rear end protrusions of the left and right cross supports, so that when multiple center floor modules 10 are combined to form a single-row center floor module 10,

[0103] As Figure 1 , Figure 2 , Figures 4-10 , the lower bracket 44 and the upper cover plate 43 together accommodate the support seat 12, and the lower bracket 44 and the upper cover plate 43 have a horseshoe-shaped mounting hole, which forms a through-horseshoe-shaped hole with the horseshoe hole 131 of the support seat 12. After the horseshoe-shaped screw rod 47 passes through the through-horseshoe-shaped hole, it can only move up and down in the horseshoe-shaped hole under the action of the large gear tray 46, and cannot rotate in the left and right directions under the action of any external force, because the horseshoe-shaped hole is limited by the horseshoe-shaped screw rod 47. After the horseshoe anti-loose piece 42 passes through the horseshoe-shaped screw rod 47, it cannot rotate around the horseshoe-shaped screw rod 47 with the horseshoe-shaped screw rod 47 as the center, because the horseshoe-shaped hole is limited by the horseshoe-shaped screw rod 47. After the hexagonal nut 41 is locked, the hexagonal nut 41 cannot rotate and cannot be loosened, which ensures that the horseshoe-shaped screw rod 41 cannot move up and down in the horseshoe-shaped hole under the action of the external force caused by the loosening of the hexagonal nut 41, so that the elastic leveling support 4 loses stable support; the large gear tray 46 is engaged with the pinion 455, and the large gear tray 46 is lifted on the horseshoe-shaped screw rod 47 to realize precise leveling through the rotation of the pinion 455; the U-shaped anti-loose pad 452 locks the hexagonal head 451, so that the leveling pinion 45 is in a static state, and the large gear tray 46 cannot change the height position on the horseshoe-shaped screw rod 47 due to any external force; through the above arrangement, the elastic leveling support 4 does not lose the leveling level due to any external force after leveling is completed, thereby ensuring the long-term stable support required by the sports venue.

[0104] As Figure 10 , Figures 12-16 shown, after the elastic leveling support 4 is leveled and locked, the lower bracket 44 and the upper cover plate 43 accommodate the support seat 12 and the cross braces on both sides of the support seat 12, and under the locking of the large gear tray 46 and the hexagonal nut 41, the cross braces on both sides of the support seat 12 are clamped and held, so that the application obtains stable support.

[0105] As Figures 6-11 shown, the large gear tray 46 has a dual role, one is as a load-bearing tray, and the other is to realize precise leveling through engagement with the pinion 455; the extension protrusion at the center position of the lower surface of the large gear tray 46 lengthens the length of the screw hole and increases the length of the thread contact with the horseshoe-shaped screw rod 47, thereby increasing the stability and load-bearing capacity of the large gear tray 46.

[0106] As Figures 6-9 , Figure 12 , Figure 13As shown, the upper half of the elastic rubber pad 49 is in the rubber pad seat 48, which contains the upper half of the elastic rubber pad 49, ensures that the elastic rubber pad 49 does not displace and disengage under the action of vibration and gravity, affects the stability support of the application and the elasticity, shock absorption and shock absorption required for sports; the rubber pad seat 48 does not limit the elastic rubber pad 49 under the action of vibration and gravity impact, provides the elasticity, shock absorption and shock absorption required for sports of the application.

[0107] As shown in Figures 6-11 , the large gear tray 46 is larger and the small gear 455 is smaller, and after the two are engaged, the arbitrary rotation of the large gear tray 46 is permanently limited by the small gear 45; in mechanics, the large gear drives the small gear to rotate, which requires a large force to be applied to the large gear, while the small gear drives the large gear to rotate, which only requires a small force to be applied to the small gear; Therefore, only a small force is required to rotate the hexagonal head 451, which can easily make the small gear 455 drive the large gear tray 46 to rotate, achieving fast and accurate leveling; The U-shaped anti-loose pad 452 locks the hexagonal head 451 and indirectly locks the large gear tray 46, thereby ensuring that the application realizes long-term stable support under the action of any impact force and gravity.

[0108] As shown in Figures 6-11 , the horseshoe anti-loose piece 42 and the U-shaped anti-loose pad 452 need to be bent to play a locking effect and a contact locking effect during installation and removal. The horseshoe anti-loose piece 42 can be replaced immediately after being damaged after disassembly and use or after being disassembled and used multiple times. The U-shaped anti-loose pad 452 can be bent flat with pliers on one side of the U-shaped opening, pulled out from the other end, and then a new U-shaped anti-loose pad 452U is inserted into the space between the hexagonal head 451 and the upper wing of the gear seat 454, and then the part protruding from the U-shaped opening on the upper wing of the gear seat 454 is bent downward to fit the vertical surface of the upper wing of the gear seat 454. This can maintain the anti-loose locking of the application during repeated installation and removal at a very small cost.

[0109] As shown in Figure 12 , Figure 16 , after the single-row central floor module 10 is assembled, the left and right sides of the single-row central floor module 10 can be simultaneously assembled with the side floor modules 11. When disassembly is required, the left and right sides of the single-row central floor module 10 can also be simultaneously disassembled. Double-sided assembly and double-sided disassembly greatly improve the installation and disassembly efficiency of the application. Each row of floor modules 1 is staggered with the previous row of modules in the left-right direction, enhancing the overall stability and stability of the application. Embodiment
