[0027] While installing the side floor modules 11 on the right side of the single-path center floor module 10, install the first side floor module 11 on the left side of the single-path center floor module 10 in a front-to-back sequence; align the left edge of the first side floor module 11 with the left edge of the single-path center floor module 10; first lift the first side floor module 11, and fit the pin hole of its left front corner corner clip 32 into the pin of the positioning clip 31 on the left side of the single-path center floor module 10, thus completing the positioning clip 31. The first side floor module 11 of the first path is connected to the corner card 32. At the same time, the first side floor module 11 of the first path can rotate and move within a certain range around the pin of the positioning card 31. At this time, the rear end of the first side floor module 11 of the first path is pushed towards the single-path center floor module 10, so that the tenon groove on the left side edge of the first side floor module 11 fits into the tenon tongue on the left side edge of the single-path center floor module 10, thus completing the docking with the single-path center floor module 10. The leveling and anti-loosening locking of the elastic leveling support 4 are completed according to the method of the first center floor module 10. Furthermore, a second side floor module 11 is installed at the rear end of the first side floor module 11. Following the same method as the first module, the corner clip 32 at the lower left corner of the second side floor module 11 is connected to the positioning clip 31 of the single-path center floor module 10, completing the connection between the second side floor module 11 and the center floor module 10. The rear end of the first side floor module 11 is then pushed towards the center floor module 10, causing the tenon on its left edge to engage with the tenon on the right edge of the single-path center floor module 10, thus completing the connection with the center floor module. The board module 10 is connected, and at the same time, the tenon on its rear edge engages with the tenon on the front edge of the previous side floor module 11, thus completing the connection with the previous side floor module 11; the pull ring of the tensioning buckle 21 at the rear end of the second side floor module 11 is hooked onto the hook head of the right rear corner fixing hook 22 of the first side floor module 11, and then the clamping handle is pressed down to complete the connection and fixation of the first side floor module 11 and the second side floor module 11; the leveling and anti-loosening locking of the elastic leveling support 4 are performed in the same way as the first one; Furthermore, following the same method as the second side floor module 11, a third side floor module 11 is installed at the front end of the second side floor module 11 at the rear end, and a fourth side floor module 11 is installed at the rear end of the third side floor module 11. The modules are assembled and leveled one by one until the first side floor module 11 on the left side of the single-path center floor module 10 is installed.

[0028] Install the second side floor module 11 on the right side of the single-path center floor module 10; on the right side of the first side floor module 11, install the second side floor module 11 in front-to-back order; first connect the corner clip 32 at the left front corner of the first side floor module 11 of the second side floor module 11 to the positioning clip 31 of the first side floor module 11, push the rear end of the first side floor module 11 so that the tenon groove on its left edge fits into the tenon tongue on the right edge of the previous side floor module 11, and complete the docking with the previous side floor module 11; Further, install the second side floor module 11 at the front end of the first side floor module 11, connect the corner clip 32 at the lower left corner of the second side floor module 11 to the positioning clip 31 of the previous side floor module 11, push the rear end of the second side floor module 11 to the left so that the tenon groove on its left edge engages with the tenon tongue on the right edge of the previous side floor module 11, completing the docking with the previous side floor module 11. At the same time, the tenon tongue on the rear edge engages with the tenon groove on the front edge of the previous side floor module 11, completing the docking with the previous side floor module 11. Hook the pull ring of the tensioning buckle 21 at the rear end of the second side floor module 11 onto the hook head of the fixing hook 22 at the right rear corner of the first side floor module 11, and then press down the clamping handle to complete the connection and fixation of the first side floor module 11 and the second side floor module 11. Level and lock the elastic leveling support 4 according to the method of the first module. Furthermore, following the installation method of the second side floor module 11, a third side floor module 11 is installed at the front end of the second side floor module 11, and then a fourth one is installed. The modules are assembled and leveled one by one until the second side floor module 11 is installed.

[0029] Furthermore, following the method of the second route, a third side floor module 11 is installed on the right side of the second side floor module 11; a fourth side floor module 11 is installed on the right side of the third side floor module 11, and so on, assembling and leveling each route until the entire area to the left of the single-route center floor module 10 is fully installed.

[0030] Another objective of this application is to provide a construction method for a universal indoor / outdoor removable, levelable, nail-free sports floor. The construction method includes the following installation, leveling, and removal steps: S1. Material preparation: The center floor module 10 and side floor modules 11, and elastic leveling support 4, are installed in the corresponding quantity and size of the site, including fasteners 2, connecting clips 3, and other components. S2. Starting from the beginning position on one side of the middle of the site, install one central floor module 10 in reverse order from back to front to form a single central floor module 10. Then, install side floor modules 11 on both sides of the single central floor module 10 one by one. Adjust the horizontal height of each floor module by turning the hexagonal head 451 with a wrench. After the horizontal adjustment is completed, connect the adjacent central floor modules 10 and the adjacent side floor modules 11 with fasteners 2. Connect the single central floor module 10 and the adjacent side floor modules 11 with connecting clips 3. Connect the adjacent side floor modules 11 with fasteners 2 until the installation of the entire site is completed. S3. Draw basketball, badminton, volleyball, tennis and other sports field lines on the upper surface of floor module 1. If the factory completes the drawing of sports field lines at the same time when painting or laying the anti-slip and wear-resistant layer, this step is not required.

[0031] In installation method S1, the elevation difference of the installation site is measured, and the elevation of the upper surface of the floor module 1 is determined based on the elevation difference. The length of the horseshoe bolt 47 is determined based on the elevation and the ground elevation difference, ensuring that when the elastic pad 49 touches the ground after leveling, the upper end of the horseshoe bolt 47 is completely exposed above the hexagonal nut 41. The standard height of this application is determined when the floor module 1, after installing the elastic leveling support 4, is placed on a level surface, and the large gear tray 46 descends to its lowest position on the horseshoe bolt 47, at which point the bottom surface of the elastic pad is above the panel. The height of the surface is the elevation of this application itself; the height of the highest point of the site ground plus the standard height of this application is used as the uniform upper surface elevation of the floor module 1 of this application; the height of the lowest point of the site ground plus the uniform upper surface elevation of this application, plus five centimeters, is the length of the horseshoe screw 47; this length ensures that during and after the leveling process of each elastic leveling support 4, regardless of the height difference of the site ground, the upper end of the horseshoe screw 47 is always fully exposed above the hexagonal nut 41, ensuring the rapid progress of the leveling and fixing locking process.

[0032] In installation method S1, after leveling, if the upper end of the horseshoe screw 47 is higher than the lower edge of the panel, cut off the part that is higher than the lower edge of the panel to prevent the horseshoe screw 47 from obstructing the assembly of the floor module 1.

[0033] In installation method S2, if the floor module 1 needs to be cut at the beginning and end, it should be cut according to actual needs. After the installation is completed, use a large strip to cover the edge of the floor for aesthetic purposes. Connect and fix the floor module 1 that is missing due to cutting at the edge of the site by drilling through holes in the strip and inserting steel bolts into the through holes.

[0034] Another objective of this application is to provide a method for removing indoor and outdoor universal detachable, levelable, nail-free sports flooring. The removal method includes the following steps: S01. At the left and right edges of the site, remove the edge trim strips, open the tensioning handle of the tensioning lock 21, and release the fastener 2 from the connection and fixation of the adjacent side floor modules 11. In the reverse order of installation, pull the side floor module 11 outward from one end of the tensioning lock 21 to lift the side floor module 11, so that the pin hole of the corner clip 32 is disengaged from the pin of the positioning clip 31, and the connection and fixation with the previous floor module is released. Remove the floor modules one by one and one by one until all the floor modules 1 are removed. S02. Using tools such as flathead screwdrivers and pliers, release the locking of the U-shaped anti-loosening washer 452 to the hexagonal head 451, release the locking of the horseshoe anti-loosening plate 42 to the hexagonal nut 41, remove the hexagonal nut 41, and remove the elastic leveling support 4 from the support base 12. S03. Place the center floor module 10, side floor module 11 and elastic leveling support 4 in a designated location for storage and replace the U-shaped anti-loosening pad 452 and horseshoe anti-loosening plate 42. At this time, the center floor module 10, side floor module 11 and elastic leveling support 4 are in a state that can be reinstalled at any time.

[0035] This application uses fasteners 2 and connecting clips 3 to connect and fix the individual floor modules 1 horizontally and vertically, ensuring the integrity of large-area installation; the application achieves a flat surface required for sports by quickly and accurately leveling the elastic leveling support 4; the application provides stable support for sports by locking the elastic leveling support 4 with anti-loosening pads; this application realizes the rapid installation, precise leveling, and rapid removal of indoor and outdoor universal nail-free sports flooring technology, as well as the reusability and re-disassembly of indoor and outdoor universal nail-free sports flooring technology.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. The specific implementation of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0039] like Figures 1-17As shown in the figure, an embodiment of this application provides an indoor and outdoor universal detachable and levelable nail-free sports floor, including a central floor module 10, side floor modules 11, fasteners 2, connecting clips 3, and elastic leveling supports 4. The central floor module 10 is connected to the side floor modules 11 on both sides by fasteners 2 and connecting clips 3. The elastic leveling supports 4 are connected and support the central floor module 10 and the side floor modules 11 from below. By connecting adjacent floor modules with fasteners 2 and connecting clips 3 and easily detachable, and by using the precise gears of the elastic leveling supports 4 for leveling, this application can be quickly installed, precisely leveled, and quickly disassembled, making it both levelable and reusable.

[0040] Obtaining the central floor module 10 and the side floor module 11: The organic and inorganic materials that can be molded in one piece are solidified and molded into one piece products by using a special one-piece molding mold; After solidification and molding, the one-piece product is taken out from the mold, which is a single one-piece molded module without through holes without protruding supports and without tenons and grooves on the left and right sides and rear facade of the central floor module 10 and the side floor module 11. Use a drilling machine to drill holes at the designated positions of each through hole to create each through hole; use a grooving machine to create grooves at the designated positions of the tenon grooves to create tenon grooves; thus obtaining the center floor module 10 and the side floor module 11; The central floor module 10 and the side floor modules 11 are placed on the painting production line and painted or covered with anti-slip and wear-resistant layers according to customer requirements. Repeat the above steps to obtain multiple center floor modules 10 and side floor modules 11.

[0041] like Figures 1-5 As shown, the upper end of the central floor module 10 and the side floor module 11 are provided with a panel, and the lower end and the back of the panel are provided with multiple protruding supports to enhance the load-bearing performance and integration of the integrated nail-free floor module 1. As an enhancement measure of this application, steel strips are built into the interior of each protruding support and cross brace to further enhance and strengthen the longitudinal and transverse deformation resistance, seismic resistance, and tensile strength of the central floor module 10 and the side floor module 11. Before molding production, the steel strips are placed in the corresponding positions of the designated parts in the special molding die of the central floor module 10 and the side floor module 11, and the steel strips can be built into the mold by normal molding production.

[0042] like Figures 1-5As shown, the central floor module 10 has fixing hooks 22 on the outer support protrusions of the lower edges of the left and right sides of the front end of the central panel 101, and tensioning buckles 21 on the outer support protrusions of the lower edges of the left and right sides of the rear end. A positioning clip 31 is provided on the outer support protrusion at the middle position of the lower edge of the left side, with the pin of the positioning clip 31 facing forward. A positioning clip 31 is also provided on the outer support protrusion at the middle position of the lower edge of the right side, with the pin of the positioning clip 31 facing backward. The side floor module 11 has corner clips 32 on the outer support protrusion at the left end of the front end, tensioning buckles 21 on the outer support protrusion at the rear end of the lower edge of the right side, fixing hooks 22 on the outer support protrusion at the front end of the lower edge of the right side, and positioning clips 31 on the outer support protrusion at the middle position of the lower edge of the right side, with the pin of the positioning clip 31 facing backward. Through these features, the application achieves quick and reusable assembly and disassembly.

[0043] like Figures 1-5 , Figure 12 As shown, the central floor module 10 has a left horizontal brace 102 on the left and a right horizontal brace 103 on the right; the side floor module 11 has a side horizontal brace 112 on the right; the left horizontal brace 102, the right horizontal brace 103, and the side horizontal brace 112 are all outside the edge of the panel, providing the necessary working space for the installation and leveling locking of the elastic leveling support 4, so that the floor module 1 of this application can be quickly leveled during assembly; like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the central floor module 10 has a left horizontal brace 102 on the left and a right horizontal brace 103 on the right; the side floor module 11 has a side horizontal brace 112 on the right; the inner surfaces of the left horizontal brace 102, right horizontal brace 103, and side horizontal brace 112 are all connected to the lower plane of the adjacent support protruding in the form of an inclined plane to ensure that the left horizontal brace 102, right horizontal brace 103, and side horizontal brace 112 protruding outside the floor module 1 provide firm support for the floor module 1; like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figures 12-16 As shown, the central floor module 10 has tenons protruding from the front facade and the left and right side facades of the central panel 101, and a tenon groove recessed into the rear facade. After multiple central floor modules 10 are assembled in the front, back, left and right horizontal directions, the front tenon connects to the rear tenon groove. The side floor module 11 and the side panel 111 have mortises recessed into the left and front facades, and tenons on the right and rear facades. When the side floor module 11 is assembled with the center floor module 10, the left mortise connects to the tenons on the left and right sides of the center floor module 10. When multiple side floor modules 11 are assembled front-to-back and on the right, the left mortise connects to the right tenon, and the front tenon connects to the rear mortise. The interlocking mortises and tenons ensure that the horizontal level, instantaneous deformation, and vibration frequency of the upper surface of the floor on both sides of the edges of adjacent floor modules 1 and the panel edges are always in the same state. This prevents athletes from being injured by shoe impacts due to different horizontal heights of adjacent panel edges during intense competition, and avoids different instantaneous deformations and vibration frequencies affecting their performance.

[0044] like Figure 4 , Figure 5 , Figure 12 , Figure 14 As shown, the support protrusions at the rear end of the back side panel 111 and the lower edge of the left side of the side panel 111 are all recessed into the rear end of the back side panel 111 and the lower edge of the left side. The recessed space accommodates the fasteners 2 and the connecting clips 3 after the floor module 1 is assembled in the front, back, left and right directions, so that the fasteners 2 and the connecting clips 3 protruding from the outer edge of the panel of the floor module 1 do not affect the smooth assembly of the floor module 1 in all directions. like Figure 5 As shown, the support protrusion below the lower edge of the left side panel 111 of the side floor module 11 forms a recessed layout to the right at the position corresponding to the support base 12; the length of the recess in the left-right direction is greater than the distance between the outer edge of the support base 12 and the right edge of the side panel 111, and the width of the recess in the front-back direction is greater than the distance between the two edges of the two limiting holes 13, ensuring that when the side floor module 11 is assembled, the part of the elastic leveling support 4 that is higher than the support base 12 and the upper surface of each cross brace will not affect the assembly of the floor module 1 due to conflict with the support protrusion.

[0045] like Figures 1-5 , Figures 12-16 As shown, the tensioning buckle 21 is equipped with a clamping handle, and the clamping handle is equipped with a pull ring. The pull ring is connected to the fixing hook 22 to realize the connection and positioning of the center floor module 10 and the side floor module 11 in the front and rear directions. The positioning card 31 is equipped with a pin, and the pin is connected to the corner card 32 to realize the connection and fixing of the side floor modules 11 adjacent to the center floor module 10 on the left and right sides, and the connection and fixing of multiple side floor modules 11 on the right side.

[0046] like Figure 12 , Figure 14As shown, the support protrudes from the lower edge of the left side of the side floor module 11. The bottom surface of the part that is not recessed is located on the upper plane of each cross brace after assembly and abuts against the upper plane of each cross brace. This allows the gravity and impact force occurring on the edge of the side floor module 11 to be quickly transmitted to each cross brace, forming a gravity support outside the mortise and tenon joint. This support complements the mortise and tenon joint, greatly reducing the impact resistance and long-term deformation resistance of the left side of the side floor module 11, and greatly enhancing the stability and robustness of this application under the impact of intense sports competitions.

[0047] like Figure 1 , Figure 2 , Figure 15 As shown, the left and right cross braces 102 and 103 of the central floor module 10 have matching recesses and protrusions at their front and rear ends. When multiple central floor modules 10 are assembled into a single row of central floor modules 10 in the front-to-back direction, the matching recesses and protrusions ensure that the left and right edges of the single row of central floor modules 10 are straight, neat, and consistent, serving as the assembly reference line for the side floor modules 11. The matching recesses and protrusions ensure that the side floor modules 11 do not shift due to the impact and pulling of the side floor modules 11 when the single row of floor modules 10 is assembled in the left and right directions, thus ensuring the smooth progress of the large-area paving of this application.

[0048] When multiple center floor modules 10 are assembled in the front-to-back direction, the front ends of the left and right cross braces of the center floor module 10 are recessed and connected to the rear ends of the left and right cross braces, which allows multiple center floor modules 10 to be assembled into a single-path center floor module 10. like Figure 1 , Figure 2 , Figures 4-10After the lower support 44 and the upper cover plate 43 jointly accommodate the support base 12, the horseshoe-shaped mounting holes of the lower support 44 and the upper cover plate 43, together with the horseshoe hole 131 of the support base 12, form a horseshoe-shaped through hole that runs vertically through the body. After the horseshoe screw 47 passes through the horseshoe-shaped through hole, due to the restriction of the horseshoe-shaped through hole, it can only move up and down in the horseshoe-shaped through hole under the lifting and lowering drive of the large gear tray 46. It cannot rotate left and right under any external force. After the horseshoe anti-loosening plate 42 passes through the horseshoe screw 47, it cannot rotate around the horseshoe screw 47 with the horseshoe screw 47 as the center because its horseshoe-shaped inner hole is restricted by the horseshoe screw 47. After rotating and locking the hexagonal nut 41, the hexagonal nut 41 cannot be rotated and cannot loosen, ensuring that the horseshoe screw 41 does not move up and down in the horseshoe-shaped through hole due to the external force of the hexagonal nut 41 loosening, thus preventing the elastic leveling support 4 from losing stable support. The large gear tray 46 meshes with the small gear 455. The rotation of the small gear 455 drives the large gear tray 46 to rise and fall on the horseshoe screw 47 to achieve precise leveling. The U-shaped anti-loosening pad 452 locks the hexagonal head 451, so that after the leveling small gear 45 is in a stationary state, the large gear tray 46 cannot change its height position on the horseshoe screw 47 due to any external force. Through the above settings, the elastic leveling support 4 will not lose its leveling level due to any external force after leveling, thus ensuring the long-term stable support required for sports fields.

[0049] like Figure 10 , Figures 12-16 As shown, after the elastic leveling support 4 is leveled and locked, the lower support 44 and the upper cover plate 43 accommodate the support base 12 and the horizontal supports on both sides. Under the locking of the large gear tray 46 and the hexagonal nut 41, the support base 12 and the horizontal supports on both sides are clamped and held, so that this application obtains stable support.

[0050] like Figures 6 to 11 As shown, the large gear tray 46 has a dual function: firstly, it serves as a load-bearing tray, and secondly, it achieves precise leveling through meshing with the small gear 455. The extended protrusion at the center of the lower plane of the large gear tray 46 lengthens the screw hole and increases the thread contact length with the horseshoe screw 47, thereby increasing the stability and load-bearing capacity of the large gear tray 46.

[0051] like Figures 6-9 , Figure 12 , Figure 13 As shown, the upper half of the elastic pad 49 is located within the pad seat 48. The pad seat 48 accommodates the upper half of the elastic pad 49, ensuring that the elastic pad 49 does not shift or detach under vibration and gravity, thus affecting the stable support of this application and the elasticity, shock absorption, and shock dissipation required for sports activities. The pad seat 48 does not restrict the elastic pad 49 from providing the elasticity, shock absorption, and shock dissipation required for sports activities under vibration and gravity impact.

[0052] like Figures 6 to 11 As shown, the large gear tray 46 is larger, and the small gear 455 is smaller. After they mesh, any rotation of the large gear tray 46 is permanently restricted by the small gear 45. Mechanically, the large gear needs to apply a large force to drive the small gear to rotate, while the small gear only needs to apply a small force to drive the large gear to rotate. Therefore, only a small force is needed to rotate the hexagonal head 451 to easily make the small gear 455 drive the large gear tray 46 to rotate, achieving rapid and precise leveling. The U-shaped anti-loosening pad 452 locks the hexagonal head 451, thereby locking the small gear 455 and indirectly locking the large gear tray 46, thus ensuring that this application can achieve long-term stable support under any impact force and gravity.

[0053] like Figures 6-11 As shown, both the horseshoe-shaped anti-loosening plate 42 and the U-shaped anti-loosening pad 452 require bending during installation and removal to achieve locking and contact locking functions. The horseshoe-shaped anti-loosening plate 42 can be replaced immediately if damaged after disassembly and repeated use. If the U-shaped anti-loosening pad 452 is damaged after disassembly and repeated use, the open side of the U-shape can be flattened with pliers and pulled out from the other end. Then, a new U-shaped anti-loosening pad 452U can be taken, inserted between the hexagonal head 451 and the upper plane of the gear seat 454, and then the part of the U-shape protruding from the upper wing of the gear seat 454 can be bent downwards to fit against the vertical surface of the upper wing of the gear seat 454. This maintains the anti-loosening locking mechanism of this application during repeated installation and removal at minimal cost. like Figure 12 , Figure 16 As shown, after the single-row center floor module 10 is assembled, the side floor modules 11 can be assembled simultaneously on its left and right sides. When dismantling is required, it can also be dismantled simultaneously on both the left and right sides of the site. The double-sided assembly and double-sided dismantling greatly improve the installation and dismantling efficiency of this application. Each row of floor modules 1 is assembled with the previous row of modules in a staggered manner in the left and right directions, which enhances the integrity and stability of this application.

Install the center floor module 10 one by one in the order from back to front; first, level and lock the first one, use a wrench to turn the hexagonal head 451 to adjust the support height of the elastic leveling support (4) one by one, adjust the horizontal height of the center floor module 10, after leveling, make the U-shaped anti-loosening pad 452 lock the hexagonal head 451, use a wrench to tighten the hexagonal nut 41, and then make the horseshoe anti-loosening plate 42 lock the hexagonal nut 41, lock the leveling state of the elastic leveling support (4) and the hexagonal nut 41; S03. Install the second center floor module 10 at the front end of the first center floor module 10, and connect and fix the adjacent center floor modules 10 with fasteners 2; after completing the leveling and locking the leveling state of the elastic leveling support (4) and the hexagonal nut 41, splice the next center floor module 10; until the entire road is installed and leveled, forming a single-road center floor module 10. S04.
