Description

Technical Field

[0001] This application relates to the field of one-piece molded nail-free sports flooring technology, specifically to a universal indoor and outdoor nail-free sports flooring that is detachable, levelable, and adjustable. Background Technology

[0002] Invention patent 2025118797469 discloses an integrated molding nail-free sports flooring technology. The flooring module consists of a central flooring module and side flooring modules. The central flooring module is used to start the first run, and the side flooring modules are assembled and installed on the left and right sides of the central flooring module. The production of the flooring modules requires an integrated molding mold. However, this dual-flooring module setup, with both the central and side flooring modules, requires the purchase / manufacturing of two different integrated molding molds, which significantly increases the investment in production equipment and production costs.

[0003] The central floor module and side floor modules, connected by clips, fasteners, and flexible leveling supports, enable a one-piece, nail-free sports floor that can be repeatedly disassembled and reassembled, and can be quickly and accurately leveled. The fasteners are equipped with tension locks and fixing hooks, which are connected by pull rings. The connecting clips include positioning clips and corner clips, which are connected by pins. Through holes need to be set on the support protrusions at relative positions, and bolts are used to install and fix the connecting clips and fasteners at the through holes. This method has the problems of too many connecting components, complicated setup, and high material and installation costs.

[0004] Invention patent 2026100908743 discloses a one-piece molded nail-free sports flooring technology that does not rely on any connecting parts outside the floor modules, such as bolts, screws, connecting clips, fasteners, etc., for connecting and fixing the floor modules. It achieves three-dimensional interlocking between adjacent floor modules in the front-back, left-right, and up-down directions after assembly, forming a complete, flat, and firmly connected large plane required for sports activities. This achieves extreme simplification of the floor modules in the one-piece molded nail-free sports flooring technology, significantly reducing material and installation costs. However, it cannot be leveled and can only be applied to flat surfaces that do not require leveling. In summary, existing detachable and levelable one-piece molded sports flooring technologies suffer from high production costs due to high investment in floor module manufacturing equipment, excessive connecting components, cumbersome setup, and high material and installation costs. Furthermore, existing simplified one-piece molded nail-free sports flooring technologies lack the functions of leveling and rapid reassembly / redisassembly, failing to meet the requirements for rapid leveling and reassembly / redisassembly when installed on uneven surfaces requiring leveling. Summary of the Invention

[0005] This application provides the following technical solution: an indoor and outdoor universal detachable and leveling nail-free sports floor, including multiple self-locking floor modules 1 and multiple leveling supports 2 disposed below the self-locking floor modules 1.

[0006] The self-locking floor module 1 is integrally formed without through holes. It has a panel 10, and a main support is provided on the back of the panel 10. The supports are connected by reinforcing supports. The main support is connected to the left and right sides of the panel 10 with a snap connector 11 and a receiving connector 12 respectively. The snap connector 11 protrudes from the left edge of the panel 10, and the receiving connector 12 protrudes from the right edge of the panel 10. The upper surfaces of the snap connector 11 and the receiving connector 12 are parallel to the upper surface of the panel 10 and flush with the back of the panel 10.

[0007] The snap-fit ​​connector 11 has a recessed clearance recess 111 on the right side of the upper surface. The right edge of the clearance recess 111 is flush with the lower edge of the left side facade of the panel 10. The bottom surface of the snap-fit ​​connector 11 has a snap-fit ​​protrusion 112 protruding from the lower surface of the main support. The snap-fit ​​protrusion 112 is trapezoidal with the left slope being higher on the left and the right slope being higher on the right and the left slope being lower on the left. The bottom of the left slope and the right slope are connected and transitioned by a bottom surface parallel to the upper plane of the panel 10. The left edge of the bottom surface is flush with the left edge facade of the panel 10.

[0008] A crossbeam 13 is provided on the lower outer side of panel 10, between the connectors 12. The bottom surface of the connector 12 is flush with the bottom surface of the crossbeam 13 and has the same width, and is connected to the bottom surface of the main support by a slope. The crossbeam 13 has multiple latches. The multiple latches include a small latch 131 between the first and second connectors 12 and a large latch 132 between the second and third connectors 12. The upper part of the small latch 131 opens into the inner side of the upper surface of the crossbeam 13 and is obliquely recessed through the left side of the crossbeam 13. The front-to-back opening width of the small latch 131 matches the front-to-back width of the latching protrusion 112, and its slope angle matches the angle of the right slope of the latching protrusion 112. The length of the inclined surface of the small latch 131 is greater than the length of the right inclined surface of the latch protrusion 112. The shortest distance between the inclined surface of the small latch 131 and the lower edge of the right side of the panel 10 is greater than the thickness from the bottom surface of the latch protrusion 112 to the lower edge of the left side of the panel 10. The large latch 132 is the same as the small latch 131 except that the opening width is twice the width of the small latch 131.

[0009] Below the inner side of the small bayonet 131, there is a small inclined platform 134 protruding from the left side of the crossbeam 13. The bottom surface of the small inclined platform 134 is flush with the lower surface of the crossbeam 13, the vertical surface is parallel to the left side of the crossbeam 13, the upper surface follows the inclined surface of the small bayonet 131, and the width in the front-to-back direction is greater than that of the small bayonet 131. Below the inner side of the large bayonet 132, there is a large inclined platform 135. Except that the width of the large inclined platform 135 in the front-to-back direction is greater than that of the large bayonet 132, the other settings of the large inclined platform 135 are the same as those of the small inclined platform 134.

[0010] The crossbeam 13 also includes a screw recess 133 recessed on the upper surface, located between the receiving joint 12 and the small bayonet 131, and between the receiving joint 12 and the large bayonet 132.

[0011] A single self-locking floor module 1 is on the left, and two self-locking floor modules 1 with their front and rear ends abutting and left and right edges aligned are assembled on the right. The large snap-fit ​​132 of the single self-locking floor module 1 matches and accommodates two parallel snap-fit ​​connectors 11 at the front and rear end joints of the two self-locking floor modules 1 on the right. The small snap-fit ​​131 matches and accommodates a single snap-fit ​​connector 11 of the self-locking floor module 1 on the right, and the lower plane of the main support on the right side of the snap-fit ​​connector 11 abuts against the upper plane of the crossbeam 13 of the single self-locking floor module 1 on the left.

[0012] The leveling support 2 includes an elastic rubber pad 21, a rubber pad seat 22, a lower connector 23, a lower screw tube 24, a fastening nut 25, an adjusting cylinder 26, an upper screw tube 27, an upper connector 28, and a clamp. The bottom of the leveling support 2 is the elastic rubber pad 21, which contacts the ground. The rubber pad seat 22 is located above the elastic rubber pad 21, and the bottom opening of the rubber pad seat 22 accommodates the upper part of the elastic rubber pad 21, thus limiting the movement of the elastic rubber pad 21. The upper surface of the rubber pad seat 22 is provided with a lower connector 23, which is a tubular circular hole. The inner wall of the circular hole is provided with a right-hand thread, and there is a threaded hole that penetrates the inner and outer walls and a pointed bolt that matches the threaded hole; the bottom of the lower connector 23 is welded and fixed to the center of the upper plane of the rubber pad 22, and a lower screw tube 24 is connected to it through the right-hand thread on the inner wall. The outer wall of the lower screw tube 24 is provided with a right-hand thread, and the upper end is flat with a rectangular hole at the center of the plane; the lower screw tube 24 is above the lower connector 23, and a fastening nut 25 and an adjusting cylinder 26 are connected to it through the thread on the outer wall. The fastening nut 25 is located below the adjusting cylinder 26.

[0013] The adjusting cylinder 26 has a hexagonal outer wall and a hollow inner wall with a circular hole. The upper half of the inner wall has a left-hand thread, and the lower half has a right-hand thread. An upper screw tube 27 is connected to the upper screw tube 26 via the left-hand thread in the upper half. The upper screw tube 27 includes a probe 271, which has a circular top and a rectangular bottom. The circular end of the probe 271 has a diameter slightly smaller than the diameter of the hollow inner hole of the upper screw tube 27 and is located within the hollow inner hole of the upper screw tube 27. A rectangular strip matching the rectangular holes at the lower end of the upper screw tube 27 and the upper end of the lower screw tube 24 is welded to the center of the lower plane of the circular end. A soft spring 272 is located inside the hollow inner hole of the upper screw tube 27 and on the upper surface of the circular end of the probe 271. The diameter of the soft spring 272 is smaller than the diameter of the circular end of the probe 271, and its lower end abuts against the probe 271. The round end has a flat top, and the upper end abuts against the lower surface of the holder base plate to exert a pushing force on the probe 271; the outer wall of the upper helical tube 27 is provided with a left-hand thread, and the upper end is connected to the upper connector 28 through the thread on the outer wall; the bottom end is flat and has a rectangular hole at the center that corresponds to the rectangular hole at the upper end of the lower helical tube 24; the rectangular holes at the lower end of the upper helical tube 27 and the upper end of the lower helical tube 24 together accommodate the rectangular strip of the probe 271;

[0014] Preferably, the length of the adjusting cylinder 26 is the sum of the length of the lower screw tube 24 exposed outside the lower connector 23 and the length of the upper screw tube 27 exposed outside the lower connector 23; the lengths of the lower screw tube 24 and the upper screw tube 27 exposed outside the lower connector 23 are both half the length of the adjusting cylinder 26; the length of the rectangular strip of the probe 271 exposed outside the bottom surface of the lower screw tube 24 is slightly greater than the length of the adjusting cylinder 26; the natural length of the soft spring 272 is greater than the length of the upper screw tube 27; the thrust of the soft spring 272 is greater than the sum of the frictional resistance generated when the circular end of the probe 271 slides freely in the circular hollow of the upper screw tube 27 and when its rectangular strip slides freely in the rectangular holes of the upper screw tube 27 and the lower screw tube 24; the soft spring 272 The thrust strength generated after arbitrary compression is less than the welding connection strength between the upper connector 28 and the lower plane of the clamp base plate, and between the lower connector 23 and the rubber pad seat 22; less than the threaded connection strength between the upper screw tube 27 and the upper connector 28, and between the lower screw tube 24 and the lower connector 23; and less than the threaded connection strength between the adjusting cylinder 26 and the upper screw tube 27 and the lower screw tube 24.

[0015] The upper connector 28 is identical to the lower connector 23 except that the inner wall of the circular hole has a left-hand thread. A clamp is located above the upper connector 28. The clamp includes a beam clamp 29, a small clamp 209, and a large clamp 2009. The beam clamp 29 has a base plate, and the upper end of the lower connector 23 is welded and fixed to the center of the lower plane of the base plate. The two long sides of the base plate of the beam clamp 29 have two upright plates 291 and two curved upright plates 292. The upright plates 291 are trapezoidal with a circular through hole at the top. The lower part of the curved upright plates 292 is trapezoidal, bent outwards from the upper edge of the trapezoid into an arc shape, and has a long through hole at the middle of the upper edge of the trapezoid. The space formed by the two upright plates 291 and the two curved upright plates 292 with the base plate is used to accommodate the beam 13. The lower plane of the base plate is located at the lower connector 23. Each side is provided with a reinforcing plate 294, which is welded to the lower plane of the bottom plate of the crossbeam clamp 29 and the outer wall facades of both sides of the lower joint 23.

[0016] T-bolt 293 is equipped with a screw rod, one end of which is welded with a cylindrical base rod, and the other end is threaded and connected to an anti-loosening nut via the thread. The arc plate 292 of the beam holder 29 is on the left and the vertical plate 291 is on the right. After the beam 13 is fitted under the connector 12, the circular through hole of the vertical plate 291 and the elongated through hole of the arc plate 292 correspond to the screw recess 133 on both sides of the connector 12 and the upper plane of the beam 13. The lower edge of the circular through hole of the vertical plate 291 is in line with the screw recess 133. The arc-shaped bottom surface is flush with the top edge of the arc-shaped plate 292 and the height of the bottom of the long through hole are lower than the arc-shaped bottom surface of the screw recess 133. When installing the T-bolt 293, the cylindrical bottom rod of the T-bolt 293 is on one side of the arc-shaped plate 292. The screw passes through the long through hole of the arc-shaped plate 292 and the circular through hole of the upright plate 291. The screw is connected to the anti-loosening nut on the outer wall of the upright plate 291 by threads. The arc-shaped bottom surface of the screw of the T-bolt 293 is fitted with the screw recess 133. At this time, tightening the anti-loosening nut will allow the crossbeam holder 29 to clamp and lock the crossbeam 13.

[0017] The small clamp 209 for snap-fit ​​connectors has a base plate that fits against the left, bottom, and right inclined surfaces of the snap-fit ​​protrusion 112. Symmetrical upright plates are provided on both sides of the base plate. The space between the upright plates and the floor is used to accommodate the snap-fit ​​connector 11 and the snap-fit ​​protrusion 112. A through hole is provided at the upper end of the upright plate for installing a T-bolt 293. After the small clamp 209 for snap-fit ​​connectors 11 and the snap-fit ​​protrusion 112 are fitted together, the lower edge of the through hole is flush with the lowest point of the recess 111. The only difference between the small clamp 209 for snap-fit ​​connectors and the large clamp 2009 for snap-fit ​​connectors is that the width of the base plate of the small clamp 209 matches the width of a single snap-fit ​​connector 11, while the width of the base plate of the large clamp 2009 matches the width of two parallel snap-fit ​​connectors 11.

[0018] The leveling support 2 is matched with the small clamp 209 and the large clamp 2009, and is used only for locking, leveling and supporting the left edge of the first self-locking floor module 1 at the beginning of the installation of this application.

[0019] The leveling support 2 is made of metal with a rust-proof surface or stainless steel. All components are manufactured in the factory and assembled in the following order: the lower connector 23 is welded to the upper surface of the rubber pad seat 22; the upper connector 28 is welded to the lower surface of the clamp's base plate; the reinforcing plate 294 is welded to both sides of the upper connector 28 and the lower surface of the clamp's base plate; the rubber pad seat 22 fits onto the elastic rubber pad 21; the lower end of the lower screw tube 24 is rotated to connect to the lower connector 23 until its end touches the upper surface of the rubber pad seat 22; the rectangular probe 271 passes downwards through the rectangular opening at the bottom of the upper screw tube 27, with its rounded top positioned on the upper screw tube 27. The soft spring 272 is inserted into the inner hole of the upper screw tube 27 and sinks to the bottom. Its bottom end touches the circular end of the probe 271, while its upper end is exposed outside the upper screw tube 27. The upper end of the upper screw tube 27 is rotated to connect to the upper connector 28 until its end touches the lower plane of the clamp base plate. At this time, the upper end of the soft spring 272 also touches the lower plane of the clamp base plate, generating a downward pushing force on the probe 271.

[0020] Next, tighten the pointed bolts of the lower connector 23 and the upper connector 28 so that their pointed ends limit and lock the lower screw tube 24 and the upper screw tube 27, preventing the lower screw tube 24 and the upper screw tube 27 from spinning out under any gravity and impact force; tighten the nut 25 from the upper end of the lower screw tube 24 downward until it touches the lower connector 23; the rectangular strip of the probe 271 passes through the inner hole of the adjusting cylinder 26, and the pointed end is inserted into the rectangular hole at the top of the lower screw tube 24. The lower screw tube 24 and the upper screw tube 27 are simultaneously connected to the adjusting cylinder 26. After rotating the adjusting cylinder 26 to the left to connect the lower screw tube 24 and the upper screw tube 27, continue to rotate the adjusting cylinder 26 to the left until its lower end touches the tightening nut 25. The T-bolt 293 is packaged separately and is not assembled. The assembly is now complete.

[0021] Because the upper screw tube 27 restricts the rotation of the lower screw tube 24 due to the tongue 271, when the adjusting cylinder 26 is rotated to the right, the lower screw tube 24 and the upper screw tube 27 extend out of the adjusting cylinder 26 at the same time in a stationary state, raising the height of the clamp; when the adjusting cylinder 26 is rotated to the left, the lower screw tube 24 and the upper screw tube 27 retract into the adjusting cylinder 26 at the same time in a stationary state, lowering the height of the clamp, thereby achieving precise leveling of the self-locking floor module 1 by the leveling support 2;

[0022] Furthermore, after adjusting to the desired height, rotate the locking nut 25 upwards until it contacts the adjusting cylinder 26, bringing the adjusting cylinder 26 to a stationary state. Then, tighten the locking nut 25 by 60 to 90 degrees to lock the leveling height. When adjusting the height by rotating the adjusting cylinder 26 to the right, ensure that the connection length of the lower screw tube 24 and the upper screw tube 27 in the adjusting cylinder 26 is at least one-third of their total length. This prevents the lower screw tube 24 and the upper screw tube 27 from coming out of the adjusting cylinder 26 and ensures that the adjusting cylinder 26 provides a firm connection and stable support for the lower screw tube 24 and the upper screw tube 27 under the action of gravity and impact.

[0023] Obtaining the self-locking floor module 1: Place organic or inorganic materials that can be molded in one piece into a special one-piece molding mold for the self-locking floor module 1. After curing and molding, remove the one-piece molded product from the mold to obtain a single self-locking floor module 1. Repeat the above steps to obtain multiple self-locking floor modules 1. Place the self-locking floor module 1 on the painting production line and paint or lay an anti-slip and wear-resistant layer according to customer requirements.

[0024] The completed self-locking floor modules 1 and the assembled leveling supports 2 are transported to the construction site. At the designated starting position on the construction site, the first row of self-locking floor modules 1 is installed in the order from back to front. After the first row of self-locking floor modules 1 is installed, the second row of self-locking floor modules 1 is installed to the right of the first row of self-locking floor modules 1. Then, the third row and the fourth row are installed to the right of the second row, until the installation of the entire site is completed.

[0025] First, install the first path; install the assembled leveling support 2 onto the first self-locking floor module 1 of the first path; take the leveling support 2 with the assembled beam clamp 29 and the corresponding number of T-bolts 293, and fasten the beam clamp 29 onto the beam 13 from below the beam 13 of the connector 12. The through holes of the upright plate 291 and the arc upright plate 292 correspond to the screw recess 133. The bottom rod of the T-bolt 293 is on the left and the screw is on the right, so that the screw passes through the long through hole of the arc upright plate 292 to the right, and passes through the through hole of the upright plate 291 along the screw recess 133 to the right. Install and tighten the anti-loosening nut at the end of the screw.

[0026] Furthermore, the leveling support 2 located below the first receiving joint 12 on the right rear side is tightened with its front-end T-bolt 293. The part exposed on the self-locking floor module 1 is cut off at the junction of the rear outer wall of the joint 28 and the reinforcing plate 294 without damaging the joint 28. The leveling support 2 located below the first receiving joint 12 on the right front side of the self-locking floor module 1 has its rear-end T-bolt 293 not tightened, and the exposed part at the front end is not fitted with T-bolt 293, waiting for the next self-locking floor module 1 to be connected at the front end.

[0027] Next, stand the self-locking floor module 1 upright with the left side facing upward, take the leveling support 2 of the small clamp 209 of the assembly clamp connector and install it on the second, third and fourth clamp connectors 11 from front to back on the left side, and tighten the T-bolt 293; lay the self-locking floor module 1 flat, take the leveling support 2 of the large clamp 2009 of the assembly clamp connector and fit it onto the clamp connector 11 at the front left corner, so that its rear end plate is attached to the rear end surface of the clamp connector 11, do not install the T-bolt 293, and wait for the next self-locking floor module 1 to be connected at the front end;

[0028] Further, leveling; on the left and right sides of the first self-locking floor module 1, use your hand or a wrench to turn the adjusting cylinder 26 of each leveling support 2 to the right; if this application is installed indoors, use a corner wrench to turn the adjusting cylinder 26 of each leveling support 2 to the right between the left edge of the panel 10 and the site wall to level; after adjusting the first self-locking floor module 1 to the required horizontal height, turn the locking nut 25 to the right so that it abuts against the lower end of the adjusting cylinder 26, fix the adjusting cylinder 26 with a wrench, and then tighten the locking nut 25 to the right by thirty to sixty degrees to form a height lock and anti-loosening of the adjusting cylinder 26, so that the leveling support 2 provides stable support for the self-locking floor module 1.

[0029] Install the second self-locking floor module 1 of the first path; following the method of the first module, install the leveling support 2 onto the crossbeam 13 and each clamping joint 11, except that the leveling support 2 is not installed on the left and right sides of the rear end; lift the second self-locking floor module 1, and place its rear end against the front end of the first self-locking floor module 1; place the clamping joint 11 at the left rear corner of the first self-locking floor module 1 in the clamping joint large clamp 2009 of the leveling support 2 at the left front corner of the first self-locking floor module 1; place the crossbeam 13 below the right rear corner receiving joint 12 in the crossbeam clamp 29 of the leveling support 2 at the left front corner of the first self-locking floor module 1; after leveling and locking the other leveling supports 2, install the T-bolts 293 on the leveling supports 2 at the front and rear end joints and tighten them.

[0030] Furthermore, following the same method as the second block of the first path, install the third and fourth blocks until the installation of the first self-locking floor module 1 is completed.

[0031] On the right side of the first self-locking floor module 1, install the second self-locking floor module 1 in reverse order from back to front. Due to the setting of the small latch 131 and the large latch 132, the front and rear end seams of the first and second adjacent self-locking floor modules 1 are staggered from the front and rear end seams of the first and second adjacent self-locking floor modules 1, and are assembled in a staggered manner. Therefore, the first self-locking floor module 1 of the second line needs to be cut into two halves in a straight line from left to right along the rear end edge of the first self-locking floor module 1 of the first line. The first half of the self-locking floor module 1 is taken as the first piece of the second line, and the second half is used for the end.

[0032] Furthermore, following the method of the first self-locking floor module 1 of the first path, the leveling support 2 of the assembly beam clamp 29 is installed on the beam 13 of the first self-locking floor module 1 of the second path; the right side of the first self-locking floor module 1 of the second path is raised to a tilted position with the left side lower and the right side higher. The locking connectors 11 located at the left front corner and the left rear corner correspond to the large locking slots 132 of the first self-locking floor module 1, and the remaining locking connectors 11 correspond to the small locking slots 131. They are inserted and placed flat below the panel 10 of the first self-locking floor module 1, in accordance with the large locking slots 132 and the small locking slots 131. During the flattening process, a pushing force is continuously applied to the left until it is flattened, thus completing the docking and assembly of the first self-locking floor module 1 of the second path with the first self-locking floor module 1.

[0033] Further, following the method of the first self-locking floor module 1 in the first path, after operating the leveling support 2 of the first self-locking floor module 1 in the second path, install the second self-locking floor module 1 at the front end of the first self-locking floor module 1 in the second path; following the method of the second self-locking floor module 1 in the first path, install the leveling support 2 of the beam clamp 29 onto the beam 13 of the second self-locking floor module 1 in the second path; lift the right side of the second self-locking floor module 1 in a tilted position with the left side lower than the right side, with the locking connectors 11 located at the left front corner and left rear corner corresponding to the large locking slots 132 of the first self-locking floor module 1, and the remaining locking connectors 11 corresponding to the small locking slots 131. Insert and flatten the module below the panel 10 of the first self-locking floor module 1, in accordance with the large locking slots 132 and the small locking slots 131, and continuously apply a pushing force to the left during the flattening process until the docking and assembly of the second self-locking floor module 1 in the second path and the first self-locking floor module 1 are completed.

[0034] Following the method of the first self-locking floor module 1 of the second path, after operating the leveling support 2 of the second self-locking floor module 1 of the second path, the third self-locking floor module 1 of the second path is installed at the front end of the second self-locking floor module 1 of the second path.

[0035] Furthermore, following the same method as the second self-locking floor module 1 of the second path, install the third and fourth modules until the installation of the second self-locking floor module 1 of the second path is completed.

[0036] Furthermore, following the method of the second self-locking floor module 1, the third and fourth channels are installed on the right side of the second channel until the installation of the entire site is completed.

[0037] 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:

[0038] S1. Material preparation: Self-locking floor modules 1 and T-bolts 293 of the appropriate quantity and installation quantity matching the site area and leveling support 2;

[0039] S2. Starting from the beginning position on any side of the site, install the first self-locking floor module 1 in the order from back to front, and then install the self-locking floor modules 1 one by one to the right of the first self-locking floor module 1; adjust the horizontal height of the self-locking floor module 1 one by one by turning the adjusting cylinder 26 with a wrench, and lock the height of the adjusting cylinder 26 with the fastening nut 25 until the installation of the entire site is completed.

[0040] S3. Draw basketball, badminton, volleyball, tennis and other sports field lines on the upper surface of the self-locking 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.

[0041] In installation method S1, the elevation difference of the installation site is measured, and the elevation of the upper surface of the self-locking floor module 1 after leveling is determined based on the elevation difference. The measurement value at the lowest point of the site is subtracted from the measurement value at the highest point of the site, and the resulting value is the total height adjustment stroke of the lower screw tube 24, the adjusting cylinder 26, and the upper screw tube 27. After completing the total height adjustment stroke, the connection length of the lower screw tube 24 and the upper screw tube 27 in the adjusting cylinder 26 is at least one-third of their own length, and the elastic rubber pad 21 touches the ground for support. At this time, the height of the upper surface of the self-locking floor module 1 is the unified upper surface elevation of this application. Since the thickness of the fastening nut 25 is relatively thin, the thickness of the fastening nut 25 is ignored and not included in the length calculation. At this time, the sum of the lengths of the lower screw tube 24 and the lower connector 23 is the length of the lower screw tube 24 and the upper screw tube 27. Twice the length of the upper screw tube 27 is the length of the adjusting cylinder 26. If the length of the adjusting cylinder 26 is set to six centimeters, then the lengths of the lower screw tube 24 and the upper screw tube 27 are three centimeters, and the total adjustment stroke is four centimeters, which can handle ground height differences of four centimeters. By increasing the lengths of the adjusting cylinder 26, the lower screw tube 24, and the upper screw tube 27 accordingly, the leveling requirements for greater height differences can be met.

[0042] In installation method S2, if the self-locking 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 edges of the self-locking floor module 1 for aesthetic purposes.

[0043] 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:

[0044] S01. On the right side of the site, remove the self-locking floor modules 1 one by one from right to left in the reverse order of installation; remove the edge trim strips, remove the T-bolts 293 of the crossbeams 13 on both sides of the front and rear end joints to release the leveling support 2 to lock the connection between the adjacent self-locking floor modules 1, lift the right side of the self-locking floor module 1 so that the right side is higher than the left side, so that the locking connectors 11, small locking slots 131, and large locking slots 132 that are interlocked with the self-locking floor module 1 of the previous row are disengaged, and the self-locking floor module 1 can be removed; remove the self-locking floor modules one by one from right to left in this way until all the self-locking floor modules 1 are removed, so that all the self-locking floor modules 1 are restored to a state where they can be reinstalled at any time;

[0045] S02. Remove all leveling supports 2; rotate the adjusting cylinder 26 to the right to disengage it from the fastening nut 25, then rotate the fastening nut 25 downward to contact the upper end of the lower connector 23. Rotate the adjusting cylinder 26 to the left to lower it until it contacts the fastening nut 25. Repeat this process to restore all leveling supports 2 to a state where they can be reinstalled at any time.

[0046] This application tilts the subsequently laid self-locking floor modules 1, causing their locking connectors 11 to extend below the panel 10 of the already laid self-locking floor modules 1, corresponding to the small locking slots 131 and large locking slots 132. Then, through a leveling action, utilizing the module's own weight and lateral thrust, the locking protrusions 112 of the subsequently laid self-locking floor modules 1 slide into the small locking slots 131 and large locking slots 132 along the inclined bottom surface of the guide slope, completing the self-fitting and self-locking of the self-locking floor modules 1. Due to the reasonable arrangement of the locking connectors 11, small locking slots 131, and large locking slots 132, forced staggered assembly is achieved, enhancing the self-locking and anti-displacement of adjacent self-locking floor modules 1, completely eliminating the need for the use or operation of any independent connecting parts. The leveling support 2 connects and fixes the individual self-locking floor modules 1 in the front-to-back direction, further enhancing the self-locking of adjacent self-locking floor modules 1. The ability to lock and fix each other ensures the integrity and wholeness of large-area paving; through the rapid and precise leveling of the leveling support 2 and the anti-loosening lock in the leveled state, this application can obtain a firm and flat large surface required for sports activities; due to its simple structure, this application can be applied to uneven ground that needs leveling indoors and outdoors with lower material costs, lower labor costs, and more efficient installation and dismantling operations.

[0073] It should be noted that, in order to achieve a precise guide slope for the snap-fit ​​protrusion 112 and a precise angled receiving surface for the small snap-fit ​​opening 131 and the large snap-fit ​​opening 132, the integral molding mold used in this application has corresponding molding cavities designed in the corresponding parts; those skilled in the art know that preparing the corresponding integral molding mold according to the product design drawing is a conventional technical means.

[0074] It is understood that the number and layout of the snap-fit ​​connector 11, snap-fit ​​protrusion 112, small snap-fit ​​opening 131, and large snap-fit ​​opening 132 are not limited to those shown in the attached drawings; for example, in another embodiment, at least two pairs or more snap-fit ​​units can be provided on both sides of the self-locking floor module 1; the core is that: the left and right adjacent self-locking floor modules 1 achieve assembly and self-locking through the integrally formed, mutually matching protrusions and recesses on the body, by tilting-flattening action.

[0075] The technical solutions in 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.

[0076] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application or its application or use; the specific implementation of this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0077] Example 1

[0078] like Figures 1-22 As shown in the figure, an embodiment of this application provides an indoor and outdoor universal detachable and leveling nail-free sports floor, including multiple self-locking floor modules 1 and multiple leveling supports 2 disposed below the self-locking floor modules 1.

[0079] Obtaining the self-locking floor module 1: Place organic or inorganic materials that can be molded in one piece into a special one-piece molding mold for the self-locking floor module 1. After curing and molding, remove the one-piece molded product from the mold to obtain a single self-locking floor module 1. Repeat the above steps to obtain multiple self-locking floor modules 1. Place the self-locking floor module 1 on the painting production line and paint or lay an anti-slip and wear-resistant layer according to customer requirements.

[0080] Steel strips are built into the internal parts of the snap-fit ​​connector 11, each main support, the connector 12, and the crossbeam 13 to further enhance and strengthen the longitudinal and transverse deformation resistance, seismic resistance, and tensile strength of the self-locking floor module 1. Before production, the steel strips are placed in the corresponding positions of the designated parts in the special one-piece molding mold of the self-locking floor module 1, and the steel strips can be built into the internal parts through normal one-piece molding production.

[0081] The advantages of using the plasticity of malleable materials for one-piece molding production are: good repeatability, simple operation, product quality is not affected by the operator and external conditions; short product molding cycle, one-time molding of complex structures, accurate product dimensions, smooth and easy surface treatment, better product stability, and better bending and compressive strength.

[0082] like Figures 1-5As shown, the self-locking floor module 1 has no through holes in any direction such as up and down, left and right, front and back, making the structure simpler. The through-hole-free molding design of the one-piece molding mold used to produce the self-locking floor module 1 further reduces the manufacturing cycle and capital cost of the one-piece molding mold and increases the production speed of the self-locking floor module 1.

[0083] like Figures 1-5 As shown, the self-locking floor module 1 has a panel 10 at the upper end and multiple main supports at the lower end and the back of the panel 10. The main supports are connected by reinforcing supports to enhance the load-bearing capacity and integration of the self-locking floor module 1.

[0084] like Figures 1-5 As shown, the snap-fit ​​protrusion 112 of the subsequently laid self-locking floor module 1 slides into the small snap-fit ​​131 and large snap-fit ​​132 along the inclined bottom surface of the guide slope, thus completing the self-fitting and self-locking of the self-locking floor module 1. Due to the reasonable setting of the snap-fit ​​connector 11, small snap-fit ​​131 and large snap-fit ​​132, the forced staggered assembly is achieved, realizing self-locking and anti-displacement in the front and rear directions.

[0085] like Figures 6-8 As shown, the shortest distance between the inclined surface of the small latch 131 and the lower edge of the right side of the panel 10 is greater than the thickness from the bottom surface of the latching protrusion 112 to the lower edge of the left side of the panel 10; the length of the right inclined surface of the latching protrusion 112 is shorter than the length of the inclined surface of the small latch 131, which also reduces the thickness from the bottom surface of the latching protrusion 112 to the lower edge of the left side of the panel 10; this setting ensures that when the self-locking floor module 1 is assembled, the latching connector 11 can be smoothly and obliquely inserted between the inclined surface of the small latch 131 and the upper panel 10 without obstruction; the latching connector 11 is provided with a relief recess 111 recessed into the right side of the upper surface, and the right edge of the relief recess 111 is flush with the lower edge of the left side of the panel 10.

[0086] Furthermore, if the distance between the crossbeam 13 and the lower edge of the panel 10 is relatively large, and there is no avoidance recess 111, the self-locking floor module 1 can still be assembled. Usually, in order to save materials and shorten the width of the self-locking floor module 1 in the left and right directions, and reduce the weight of the self-locking floor module 1 to facilitate the stacking and transportation of the self-locking floor module 1, the crossbeam 13 is usually closer to the lower edge of the right side of the panel 10. If there is no avoidance recess 111, when the assembly is leveled, because the bottom surface of the snap-fit ​​protrusion 112 and the right slope meet the intersection, when sliding down the slope of the small snap-fit ​​131, the upper surface of the snap-fit ​​joint 11 will be restricted by the lower edge corner of the upper panel 10, so that the snap-fit ​​protrusion 112 cannot fit into the small snap-fit ​​131, and thus cannot be leveled and cannot be assembled. When the self-locking floor module 1 is leveled, the avoidance recess 111 allows the upper surface of the snap-fit ​​joint 11 to avoid the restriction of the lower edge corner of the upper panel 10, so that the assembly can be completed smoothly.

[0087] like Figures 1-11 As shown in Figure 20, the self-locking floor modules 1 that are adjacent in the front-to-back and left-to-right directions, with matching and interlocking snap-fit ​​protrusions 112 and small snap-fit ​​slots 131 and large snap-fit ​​slots 132, interlock and abut against the snap-fit ​​connectors 11 and receiving connectors 12 on the back of the adjacent panels 10, not only form mutual connection and positioning in the left-to-right and up-down directions for the adjacent self-locking floor modules 1, but also, due to the reasonable setting of the small snap-fit ​​slots 131 and large snap-fit ​​slots 132, allow the self-locking floor modules 1 to be assembled only in a staggered left-to-right direction, forming mutual connection and positioning in the front-to-back and up-down directions for the adjacent self-locking floor modules 1. This achieves the three-dimensional locking effect of mutual locking, positioning, and limiting in the front-to-back, up-down, and left-to-right directions through the assembly of the self-locking floor modules 1 alone, enhancing the robustness, integrity, and completeness required for large-area sports scenarios in this application; Figures 3-6 , Figures 9-11 As shown, due to the small latches 131 and 132, the load-bearing capacity of the crossbeam 13 is weakened at these locations. The small ramps 134 and 135, wider than the small latches 131 and 132, reinforce these locations, ensuring that the crossbeam 13 is not affected by the gaps in the small latches 131 and 132, thus ensuring the load-bearing performance and stable support of the self-locking floor module 1 after assembly. The upper ramps of the small ramps 134 and 135 follow the ramps of the small latches 131 and 132, facilitating demolding after production. The bottom surfaces of the small ramps 134 and 135 are flush with the bottom surface of the crossbeam 13, facilitating the stacking of the self-locking floor module 1 after production.

[0088] like Figures 1-6 , Figures 9-22 As shown, the self-locking floor module 1 has a snap-fit ​​connector 11 on its left long side, with a snap-fit ​​protrusion 112 on the snap-fit ​​connector 11. A crossbeam 13 is provided on the right side, with a small snap-fit ​​slot 131 and a large snap-fit ​​slot 132 that match and engage with the snap-fit ​​connector 11. This allows adjacent self-locking floor modules 1 to connect and mutually limit each other in the left and right directions. By raising the right self-locking floor module 1 to make its left side lower than its right side, the left-right connection and positioning can be released. The leveling support 2 has clamps located below the crossbeam 13 and on both sides of the joint between adjacent self-locking floor modules 1, and below the edges of the first row of adjacent self-locking floor modules 1 on the left side of the site, supporting and connecting adjacent self-locking floor modules 1. Removing the T-bolts 293 allows the crossbeam 13 and snap-fit ​​connector 11 to be released from the clamps, thus releasing the connection and fixation in the front-to-back direction. Through the above settings, the rapid and repeated assembly and disassembly of this application can be achieved.

[0089] like Figures 12-22As shown, the leveling support 2 is provided with a lower screw tube 24, an upper screw tube 27 and a matching adjusting cylinder 26. The self-locking floor module 1 can be quickly leveled during assembly by simply rotating the adjusting cylinder 26 to adjust the height of the upper surface.

[0090] like Figures 12-19 As shown, the leveling support 2 is equipped with a crossbeam clamp 29. On the right side of the joint between adjacent self-locking floor modules 1, it connects and fixes the adjacent self-locking floor modules 1. The crossbeam clamp 29 spans the joint between adjacent self-locking floor modules 1 and connects the two crossbeams 13. When the self-locking floor modules 1 form a three-dimensional lock that is mutually locked, positioned, and limited in the front-to-back, up-down, and left-to-right directions, it strengthens the connection and locking of adjacent self-locking floor modules 1 in the front-to-back direction, ensuring the flatness of the joint in the front-to-back direction and enhancing the flatness, firmness, reliability, and durability of this application for sports scenarios.

[0091] like Figure 12 Figure 14~ Figure 19 As shown, the elastic rubber pad 21, in contact with the ground, provides elasticity, rebound, and cushioning for the entire flooring system. The rubber pad seat 22 limits the elastic rubber pad 21 to prevent displacement under the vibration and impact forces during sports activities. The lower connector 23 is welded to the upper surface of the rubber pad seat 22 and connects to the lower screw tube 24 via a right-hand thread on the inner wall. The upper connector 28 is welded to the lower surface of the clamp base plate and has a left-hand thread on the inner wall for connecting to the upper screw tube 27. Both the lower connector 23 and the upper connector 28 have threaded holes that penetrate the outer wall and pointed bolts that match the threaded holes. The lower connector 23 connects to the lower screw tube 24, and the upper connector 28 connects to the upper screw tube 27. Afterwards, tighten the pointed bolts so that the pointed ends penetrate the upper and lower threaded tubes. This prevents the lower threaded tube 24 and the upper threaded tube 27 from rotating in the lower connector 23 and the upper connector 28 under the vibration and violent impact generated by sports activities, which would affect the level of the self-locking floor module 1 after leveling, or cause them to come loose from the lower connector 23 and the upper connector 28, causing the leveling support 2 to lose stable support for the self-locking floor module 1. If the length of the lower threaded tube 24 and the upper threaded tube 27 cannot meet the requirements of the new site due to changes in elevation, the pointed bolts can be removed to quickly replace the lower threaded tube 24 and the upper threaded tube 27.

[0092] like Figure 12 , Figure 13 , Figure 15 , Figure 19As shown, the outer wall of the adjusting cylinder 26 is hexagonal. Compared with a cylindrical shape, the hexagonal shape has stronger support capacity and is easier to rotate with a wrench. The upper half of the inner wall of the adjusting cylinder 26 is provided with a left-hand thread and is connected to the upper threaded tube 27 through the left-hand thread. The lower half is provided with a right-hand thread and is connected to the lower threaded tube 24 through the right-hand thread. When the adjusting cylinder 26 is rotated to the left, the lower threaded tube 24 and the upper threaded tube 27 extend out of the adjusting cylinder 26 at the same time. When the adjusting cylinder 26 is rotated to the right, the lower threaded tube 24 and the upper threaded tube 27 retract into the adjusting cylinder 26 at the same time, forming a bidirectional extension and retraction in both directions.

[0093] Furthermore, the circular top end of the probe 271 is inside the upper screw tube 27, and the rectangular strip at the bottom end is in the corresponding rectangular hole at the upper end of the lower screw tube 24 and the bottom end of the upper screw tube 27; after the leveling support 2 is installed, before leveling, the crossbeam 13 or the clamping joint 11 restricts the clamp, the clamp restricts the upper joint 28, the upper joint 28 restricts the upper screw tube 27, and the upper screw tube 27 restricts the lower screw tube 24 through the rectangular strip of the probe 271, so that the lower screw tube 24 cannot rotate in any direction under the influence of external force;

[0094] Furthermore, during the leveling process, the adjusting cylinder 26 rotates. Because the upper screw tube 27 restricts the lower screw tube 24 through the rectangular strip of the probe 271, the lower screw tube 24 cannot rotate with the adjusting cylinder 26. It can only extend and retract synchronously with the upper screw tube 27 in the adjusting cylinder 26, ensuring the smooth leveling process of this application.

[0095] Furthermore, after leveling, under any gravity, vibration, or impact in a motion scenario, the lower screw tube 24 cannot rotate in any direction due to the restriction formed by the rectangular strip of the upper screw tube 27 through the probe 271, causing a change in the leveling height state of the self-locking floor module 1. This, in turn, restricts the rotation and displacement of the rubber pad seat 22 and the elastic rubber pad 21 under any gravity, vibration, or impact in a motion scenario, ensuring the firmness, flatness, and durability of this application in a motion scenario.

[0096] Furthermore, the rectangular strip of the probe 271 protruding from the bottom surface of the lower screw tube 24 is slightly longer than that of the adjusting cylinder 26. When the adjusting cylinder 26 touches the lower screw tube 24 and the upper screw tube 27 during assembly, before they are rotated together, the rectangular strip of the probe 271 passes through the adjusting cylinder 26 and inserts into the rectangular hole of the lower screw tube 24, restricting the rotation of the lower screw tube 24. This allows the adjusting cylinder 26 to synchronously connect the lower screw tube 24 and the upper screw tube 27 to achieve accurate synchronization of subsequent leveling, and to ensure that the lower screw tube 24 and the upper screw tube 27 are the same length in the adjusting cylinder 26 after leveling. This ensures that the adjusting cylinder 26 provides the same reasonable rigid connection support to the lower screw tube 24 and the upper screw tube 27, thereby achieving long-term and firm support for the self-locking floor module 1 by the leveling support 2 after leveling, enhancing the strength and durability required for sports scenarios.

[0097] like Figure 12 , Figure 13 , Figure 15 , Figure 19 As shown, a soft spring 272 is installed inside the circular hollow of the upper solenoid 27; the lower end of the soft spring 272 abuts against the circular end of the probe 271, and the upper end abuts against the lower plane of the clamp base plate, thus supporting the probe 271. A downward thrust is generated; when the adjusting cylinder 26 rotates to the right to the maximum height adjustment stroke, and the upper and lower solenoids extend out of the adjusting cylinder 26 synchronously, the distance between them in the adjusting cylinder 26 gradually increases. The thrust of the soft spring 272 on the probe 271 ensures that the rectangular strip of the probe 271 is always in the rectangular hole of the lower solenoid 24 under any circumstances, and always maintains the rotation restriction on the lower solenoid 24. This prevents the rectangular strip of the probe 271 from being dislodged from the rectangular hole of the lower solenoid 24 during the assembly process of the leveling support 2 due to shaking, bumping, or reversal of the upper and lower positions by the assembly operator, or sliding friction resistance between the rectangular hole and the rectangular strip. This would cause the synchronous action in the inner hole of the adjusting cylinder 26 to fail without being visible to the naked eye, creating a hidden danger and causing serious consequences or even rework for the subsequent leveling and stable support of the leveling support 2.

[0098] Furthermore, when the adjusting cylinder 26 rotates to the left, the lower end of the rectangular strip of the probe 271 also gradually descends. When the adjusting cylinder 26 rotates to the lowest position, the lower end of the rectangular strip of the probe 271 touches the upper surface of the rubber pad 22, and the top end is basically level with the lower edge of the upper connector 28. The height space of the upper connector 28 becomes the storage space for the soft spring 272.

[0099] Furthermore, the thrust of the soft spring 272 is greater than the sum of the frictional resistance generated when the circular end of the probe 271 slides freely in the circular hollow of the upper screw tube 27 and its rectangular strip slides freely in the rectangular holes of the upper screw tube 27 and the lower screw tube 24, ensuring that the thrust of the soft spring 272 on the probe 271 is not affected by the sliding frictional resistance.

[0100] Furthermore, the thrust strength generated by the soft spring 272 after arbitrary compression is less than the welding connection strength between the upper connector 28 and the lower plane of the clamp base plate, and between the lower connector 23 and the rubber pad seat 22; less than the threaded connection strength between the upper screw tube 27 and the upper connector 28, and between the lower screw tube 24 and the lower connector 23; and less than the threaded connection strength between the adjusting cylinder 26 and the upper screw tube 27 and the lower screw tube 24, so as to prevent the soft spring 272 from damaging the connection strength and support rigidity of the leveling support 2.

[0101] like Figure 12 , Figure 15 , Figure 18 , Figure 19As shown, under the weight of the self-locking floor module 1 and the gravity generated by the sports competition, the adjusting cylinder 26 will not rotate to the right due to gravity, but will only rotate to the left to lower its position, shortening the completed leveling stroke and changing the leveling state. The locking nut 25 is usually used to tighten and prevent loosening of bolts and nuts in wind power facilities. Its characteristic is that after contacting the adjusting cylinder 26, tightening it by 60 to 90 degrees will exert its anti-loosening property, preventing the adjusting cylinder 26 from rotating to the left to change its downward position. After rotation locking, it can only be loosened by manual rotation. When releasing the anti-loosening locking of the locking nut 25, it cannot be loosened and disassembled by directly rotating the locking nut 25. The adjusting cylinder 26 must first be rotated to the right to raise it and remove it from contact with the locking nut 25 before the locking nut 25 can be rotated. Therefore, after the adjusting cylinder 26 is locked and leveled by the locking nut 25, no vibration or gravity can cause the adjusting cylinder 26 to lower its position. The downward position change caused by the rotation renders the leveling state ineffective, affecting the leveling locking and long-term stable support of this application.

[0102] like Figure 14 , Figure 15 As shown, the reinforcing plate 294 is welded to both sides of the upper connector 28 and the lower plane of the clamp base plate to enhance the load-bearing strength of the base plate and the connection strength between the upper connector 28 and the clamp. For example, the beam clamp 29 needs to clamp a long beam 13 to increase clamping stability, so the base plate is long. The reinforcing plate 294 is on the lower plane of the base plate to enhance the lifting capacity of the beam clamp 29 for the beam 13 and enhance the long-term load-bearing performance and durability of the base plate.

[0103] like Figure 12 , Figure 14 , Figure 15 , Figures 18-20 As shown, after the beam clamp 29 is fitted under the connector 12 to accommodate the beam 13, the lower edge of the circular through hole of the upright plate 291 is flush with the arc-shaped bottom surface of the screw recess 133. The height of the trapezoidal upper edge of the arc-shaped upright plate 292 and the bottom of the long through hole is lower than the arc-shaped bottom surface of the screw recess 133. The cylindrical bottom rod of the T-bolt 293 is located on one side of the arc-shaped upright plate 292, and the anti-loosening nut is connected to the outer wall of the upright plate 291 by thread. The arc-shaped bottom surface of the screw of the T-bolt 293 is fitted into the screw recess 133. The tension force generated when tightening the anti-loosening nut of the T-bolt 293 pulls the crossbar on one side of the arc-shaped upright plate 292 through the screw. Because the height of the bottom of the long through hole of the arc-shaped upright plate 292 is lower than the screw recess 133, the arc-shaped wings that bend outward on both sides of the arc-shaped opening exert pressure on the crossbar that is pulled inward, causing it to slide downward along the arc-shaped wings, forcing the T-bolt 293 to... The screw is recessed into the screw 133, which forms a limit on the crossbeam clamp 29, preventing the crossbeam clamp 29 from shifting left and right on the crossbeam 13 due to vibration, gravity and impact, and enhancing the stable support capability of the leveling support 2 for the self-locking floor module 1.

[0104] Furthermore, under the tension of the T-bolt 293, the outward bending of the arc-shaped wings of the arc plate 292 generates elastic arch tension rebound force, which superimposes and enhances the tension of the T-bolt 293, enabling the crossbeam clamp 29 to exert a greater clamping force on the crossbeam 13.

[0105] Further improve the ability of the leveling support 2 to provide stable support for the self-locking floor module 1 through the crossbeam 13; enhance the stability, durability and flatness of this application in sports scenarios under high-frequency violence and high-frequency gravity impact by setting T-bolts 293, screw recesses 133 and arc-shaped upright plates 292;

[0106] Furthermore, during large-scale installation, the T-bolt 293 at the rear end of the crossbeam clamp 29 below the right front corner of the first self-locking floor module 1 on the second path is not tightened, and the T-bolt 293 is not installed at the front end, to facilitate the docking of the second self-locking floor module 1. When the second self-locking floor module 1 is assembled at the front end of the first module, during the tilting and leveling process, the left side corner of the bottom surface of the crossbeam 13 at the right rear corner will first touch the curved plate 292. At this time, if a straight plate is used without the curved setting, even if the T-bolt 293 at the rear end of the first module on the crossbeam 13 is not tightened, the upper edge of the straight plate will still obstruct the left side corner of the bottom surface of the crossbeam 13 at the right rear corner of the second module, preventing it from being leveled and thus preventing the assembly and docking. The curved setting of the curved plate 292 avoids obstructing the assembly, allowing the second self-locking floor module 1 to be leveled smoothly, and the bottom surface of the crossbeam 13 at the right rear corner to smoothly enter the crossbeam clamp 29, completing the assembly.

[0107] like Figure 12 , Figure 15 , Figure 16 , Figures 20-22 As shown, the leveling support 2 is matched with the small clamp 209 for locking, leveling, and supporting the single clamp 11 on the left edge of the first self-locking floor module 1 during installation; the leveling support 2 is matched with the large clamp 2009 for locking, leveling, and supporting the first self-locking floor module 1 during installation. On the left side edge, two locking connectors 11 are arranged side by side for locking, leveling, and supporting the adjacent front and rear self-locking floor modules 1; the difference between the two is that they match a single locking connector 11 and match two parallel locking connectors 11; the base plate fits against the left, bottom, and right inclined surfaces of the locking protrusion 112, which is also trapezoidal, and can prevent the base plate of the small clamp 209 or the large clamp 2009 of the locking connector from sliding in the left and right directions; the lower edge of the through hole on the upright plate is flush with the lowest point of the relief recess 111, so that the T-bolt 293 cannot be moved after being locked by the constraint of the relief recess 111; through the double displacement setting of the trapezoidal base plate and the relief recess 111, the support stability of the left side edge of the first self-locking floor module 1 at the beginning of this application is ensured after leveling.

[0108] like Figures 9-11 As shown in Figures 18 and 20, after assembly, the snap-fit ​​connector 11 on the left side of panel 10, the receiving connector 12 on the right side of panel 10, and the small snap-fit ​​131 and large snap-fit ​​132 on the crossbeam 13 form a two-sided interconnection, two-sided mutual support, two-sided mutual limiting and positioning, and two-sided mutual locking between adjacent self-locking floor modules 1 after assembly, thereby enhancing the overall connection strength after large-area paving of this application; the structure is simple, which is conducive to the rapid assembly of self-locking floor modules, simplifies the installation process, reduces the technical content of installation, and realizes the simple and rapid installation operation of this application;

[0109] Furthermore, the snap-fit ​​protrusion 112 of the self-locking floor module 1 and the small snap-fit ​​131 and large snap-fit ​​132 of the adjacent self-locking floor modules 1 on the left and right are all in a fitted state. Under the resistance and restriction of the panel 10 against the snap-fit ​​connector 11, the small snap-fit ​​131 and large snap-fit ​​132 on either side in the left and right directions cannot change their own height by moving up and down, so that the small snap-fit ​​131 and large snap-fit ​​132 will change their height, causing the fitted state to change or to disengage. This will cause the adjacent self-locking floor modules 1 to lose mutual restraint and positioning after assembly, resulting in positional changes or even disengagement.

[0110] Furthermore, after assembly, starting from the second row, multiple locking connectors 11 of adjacent self-locking floor modules 1 are all located below the panel 10 of the left self-locking floor module 1, and the upper surface of the locking connectors 11 abuts against the lower surface of the panel 10 of the adjacent self-locking floor modules 1; multiple receiving connectors 12 are all located below the panel 10 of the right self-locking floor module 1. The locking connectors 11 and receiving connectors 12 that probe into each other, at this time, due to the abutment and restriction of the panel 10 and the crossbeam 13, each self-locking floor module 1 exerts the same multiple limiting effect on the self-locking floor modules 1 on its left and right sides in terms of up and down, front and back, and left and right.

[0111] Furthermore, the edges of the left and right long side panels 10 of a single self-locking floor module 1 differ from the edges of the short side panels 10 at the front and rear ends. The edges of the panels 10 between adjacent locking joints 11 on the left and right long sides are the weakest parts of the entire self-locking floor module 1 structure because they lack rigid support underneath. After assembly, adjacent self-locking floor modules 1 interlock and abut against the locking joints 11 and bearing joints 12 on the back of adjacent panels 10, reinforcing the weakest edges of the panels 10 they abut against, forming strong support in both directions. Gravity and violent impacts occurring on either side of the long side of the panel 10 and between two adjacent locking joints 11 are borne and quickly dispersed by the locking joints 11 and bearing joints 12 of the adjacent floor modules below, thus strengthening the structural strength and overall service life of this application in sports scenarios against long-term violent impacts.

[0112] Furthermore, the interlocking connectors 11 and 12 ensure the consistency of flatness of adjacent panels 10 after assembly; when athletes walk, run, jump, and step on the upper surfaces of the panels 10 in the front-back direction of the adjacent self-locking floor modules 1 after assembly, and on the sides of the panel 10, the same instantaneous deformation and vibration frequency, as well as the same physical and mechanical properties such as elasticity, shock absorption, buffering, and rebound are generated at the edge joints of the adjacent panels 10 when the feet generate downward gravity and impact force at the edge joints of the adjacent panels 10, the edge joints and the sides of the edge joints generate the same physical and mechanical properties such as elasticity, shock absorption, buffering, and rebound, ensuring that the athletes can perform their competitive skills normally in the large venues of this application when conducting sports competitions and fitness activities;

[0113] Furthermore, after assembly, due to the restriction of the locking connector 11, the self-locking floor module 1 is disconnected from its adjacent self-locking floor modules 1 on the left and right. It can only be disengaged by tilting the locking protrusion 112 from the small locking slot 131 and the large locking slot 132. If two adjacent self-locking floor modules 1 on the left and right are disconnected from the self-locking floor module 1 on the right, it can only be done by tilting the right side to make the locking connector 11 on the left side disengage from the resistance restriction of the panel 10 of the self-locking floor module 1 on the left side, and the locking protrusion 112 disengage from the small locking slot 131 and the large locking slot 132 of the self-locking floor module 1 on the left side. At this time, since all the self-locking floor modules 1 assembled in the right direction are connected and limited to form a whole, they all need to be disconnected from the ground and tilted at the same angle with the same horizontal plane. This is obviously impossible and cannot happen.

[0114] Furthermore, all the self-locking floor modules 1 are laid in a staggered pattern, with mutual positioning and limiting between each other, transforming from individual units into a whole. When the joints of all the self-locking floor modules 1 on the left and right sides are subjected to vertical violent impact, the interlocking connection between the interlocking protrusion 112 and the small and large locking slots 131 will fail unless all the self-locking floor modules 1 directly or indirectly connected to it tilt together on the left, right, front, and rear sides. This is obviously impossible and cannot happen. Therefore, under the impact of any force in a sports scenario, adjacent self-locking floor modules 1 will not experience interlocking connection failure or mutual limiting failure.

[0115] Furthermore, after assembly, because the lower plane of the main support below the left and right edge joints abuts against the crossbeam 13, the gravity and impact force occurring at the left and right edge joints of the self-locking floor module 1 can be directly and quickly transmitted to the crossbeam 13, greatly reducing the impact of gravity and violent impact on the left and right edge joints, improving impact resistance and long-term deformation resistance, and greatly enhancing the long-term stability and firmness of this application under the impact of intense sports competitions; the crossbeam 13 protrudes from the right edge of the panel 10 and is located at the far right of the self-locking floor module 1, which can maximize the performance of resisting violent impact from the left side; based on the above, in addition to the connection, fixation and locking of the leveling support 2 at the right front and rear edge joints of adjacent self-locking floor modules 1, in sports scenarios with large-area paving, when any violent impact or gravity generated by any movement acts on the splicing edge of adjacent self-locking floor modules 1, it will not cause the adjacent self-locking floor modules 1 to tilt at any angle, thus preventing connection and positioning limit failure.

[0116] Example 2.

[0117] The difference between this embodiment and Embodiment 1 is that: the length of the adjusting cylinder 26 remains unchanged, while the lengths of the lower screw tube 24 and the upper screw tube 27 are increased, so that after the lower screw tube 24 and the upper screw tube 27 abut in the adjusting cylinder 26, the length of the lower screw tube 24 exposed in the adjusting cylinder 26 can accommodate the probe 271, and the upper screw tube 27 exposed in the adjusting cylinder 28 can accommodate the soft spring 272 in a compressed state. The lower screw tube 24 is directly fixed to the rubber pad 22 and the upper screw tube 27 is directly fixed to the clamp through welding or other fixed connection methods. This embodiment does not include the lower connector 23 and the upper connector 28, and the rest of the structure is the same as that of Embodiment 1.

[0118] The above embodiment provides an indoor / outdoor universal detachable and adjustable nail-free sports floor. Through the single-module self-locking floor module 1 and the absence of through holes in any direction (up, down, left, right, front, back), the manufacturing cycle and cost of the integrated molding die are further reduced, while the production speed of the self-locking floor module 1 is increased. The self-locking floor module 1 is secured using the snap-fit ​​connector 11, snap-fit ​​protrusion 112, small snap-fit ​​slot 131, and large snap-fit ​​slot 132. The self-locking and self-embedding mechanism does not rely on any connecting parts independent of the self-locking floor module 1 for connection and positioning between floor modules. It only requires simple operations such as raising, pushing in, and leveling, achieving a three-dimensional locking effect where the self-locking floor module 1 itself quickly assembles and forms mutual locking, positioning, and limiting in all directions. The small inclined platform 134 and large inclined platform 135 reinforce the small latch 131 and large latch 132, ensuring the load-bearing capacity and stable support of the crossbeam 13. Removing the T-bolt 293 allows the crossbeam 13 to be released from the crossbeam clamp 29, enabling rapid disassembly. The adjusting cylinder 26 and the lower screw tube 24 are connected by reverse threads to the upper screw tube 27, and the probe 271 synchronously restricts the lower screw tube 24 and upper screw tube 27, achieving synchronous bidirectional extension and retraction of the leveling support 2. The adjusting cylinder 26 provides the same reasonable rigid connection support to the lower screw tube 24 and upper screw tube 27, thus enabling the leveling support 2 to provide the same reasonable rigid connection support to the self-locking floor module 1. The system provides precise and rapid leveling and long-term stable support, and locks the leveled state through pointed bolts and fastening nuts 25. The arc effect of the arc plate 292, the tension locking of the T-bolt 293, and the limiting of the screw recess 133 achieve and enhance the firm and stable clamping support of the leveling support 2 on the crossbeam 13. The arc setting of the arc plate 292 and the recess setting of the avoidance recess 111 eliminate assembly obstacles, enabling smooth assembly of the self-locking floor module 1. The setting of the leveling support 2 matching the small clamp 209 and the large clamp 2009 of the clamp joint achieves locking, leveling, and support of the left edge of the first self-locking floor module 1 during installation. This application, through the self-interlocking and self-locking between single floor modules, precise leveling, and repeated disassembly and assembly, can be quickly installed on uneven ground that needs leveling, further reducing material and production costs, improving the utilization efficiency of nail-free sports flooring materials, and improving the utilization efficiency of the site.

For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
