Description

Technical Field

[0001] This application relates to the technical field of sports wood floors, and particularly to an indoor and outdoor universal assembled nail-free sports wood floor. Background Art

[0002] Ball sports such as basketball, volleyball, and badminton are the main sports and fitness activities for people. The physical and mechanical properties of sports wood floors, such as shock absorption, shock rebound, etc., can enable athletes and sports and fitness enthusiasts to avoid or reduce the irreversible impact damage to the ankle joints, knee joints, hip joints, spine, and even the brain caused by the impact from the ground during intense running and jumping on the sports wood floor, and at the same time help athletes and sports and fitness enthusiasts to give full play to and improve their sports competition levels.

[0003] Application document 2024118972139 discloses an indoor and outdoor universal nail-free sports wood floor, which consists of a floor module with leveling holes and fixing seats, a leveling hole plugging plate, and an elastic eccentric support device. The elastic eccentricity solves the reasonable force support for large inclination angles and large height differences, and the floor module can be quickly and accurately leveled by screws, leveling holes, fixing seats, and leveling hole plugging plates; however, on a flat ground without inclination angles, height differences, and without the need for floor leveling operations, the leveling function and eccentric support function formed by the combination of the leveling holes, fixing seats, leveling hole plugging plates, and elastic eccentric support devices in this disclosed technology are wasted and rendered useless. Applying this disclosed technology to a flat ground without inclination angles, height differences, and without the need for floor leveling operations is obviously too costly.

[0024] Repeat the above molding and post-treatment steps to obtain multiple elastic floor modules 1.

[0025] The locking device 2 is made of metal and is galvanized for rust prevention. The locking device 2 includes a bottom beam 21, a self-locking arm 22, a push-locking arm 23, and a thrust device 24. The bottom beam 21 is a rectangular parallelepiped, and a long fork 211 is provided at the left end. The fork of the long fork 211 opens at the vertical surface of the left end of the bottom beam 21. The upper and lower wing edges of the fork are provided with shaft holes that are symmetrical up and down and pass through the two wings, and shafts that match the shaft holes. The bottom beam 21 is also provided with two corresponding ┫-shaped through holes of the same size: a first through hole 212 and a second through hole 213. The ┫-shaped through holes penetrate the bottom beam 21 and open at the upper and lower corners on the inner side of the bottom beam 21. The second through hole 213 is provided at the right end of the bottom beam. The first through hole 212 is provided between the second through hole 213 and the long fork 211, close to the long fork 211. The spacing between the through hole 212 and the second through hole 213 is the same as the bottom width of the main supporting foot 11; the first through hole 212 and the second through hole 213 are both provided with symmetrical axial holes and matching shafts that pass through the bottom beam 21 from top to bottom at the edge of the ┫-shaped opening; a screw hole and a positioning pin 214 are provided at a quarter of the spacing between the first through hole 212 and the second through hole 213, close to one side of the first through hole 212, and the outer wall at the bottom of the positioning pin 214 is provided with a thread, which is threadedly connected to the screw hole and fixed to the inner vertical surface of the bottom beam 21; the positioning pin 214 matches the front positioning hole 132, the right positioning hole 152, and the right rear positioning hole 161.

[0026] The self-locking arm 22 includes a connecting arm 221, a top rod hole 2211, a limiting arm 222, and a top rod 223; a semi-elliptical special-shaped joint is provided at the rear end of the connecting arm 221, and the special-shaped joint is provided with an axial hole matching the axial hole and the axis of the second through hole 213; the connecting arm 221 is connected to the bottom beam 21 through the special-shaped joint, and can swing around the axis outward within a certain range, and the front end is vertically connected to the limiting arm 222 at 90 degrees to form a 𠃎 shape;

[0027] The connecting arm 221 is provided with a rectangular top rod hole 2211 that passes through the left and right side facades. The top rod hole 2211 is provided with a symmetrical shaft hole that passes through the connecting arm 221 and the top rod hole 2211 up and down, and a shaft that matches the shaft hole. The front end of the right side facade of the top rod 223 is an arc-shaped facade, and the rear end facade is an inclined surface that is higher on the left and lower on the right. The top rod 223 is provided with a protruding portion that protrudes from the right side facade, and the protruding portion is provided with a shaft hole that matches the top rod hole 2211. The shaft hole and the shaft that match, the shaft hole of the protruding part, the shaft hole corresponding to the push rod hole 2211 and the shaft are connected to the connecting arm 221, so that the push rod 223 can rotate around the axis within a certain range; when the arc-shaped vertical surface of the front end of the push rod 223 is flush with the right vertical surface of the connecting arm 221 under the push of external force, the rear end contacts the inner vertical surface of the bottom beam 21, so that the self-locking arm 22 can no longer swing outward around the axis to expand, forming a limit lock for the self-locking arm 22.

[0028] The limiting arm 222 is matched with the left front limiting groove 121 of the elastic floor module 1. The left-right length of the limiting arm 222 is the same as the length of the left front limiting groove 121, and the front-back width is twice the depth of the left front limiting groove 121. The upper and lower outer corners at the front end of the limiting arm 222 and the outer corner at the left end are provided with inclined surfaces.

[0029] The push-lock arm 23 includes an outer swing arm 231, a long ejector rod hole 2311, a chuck 232, a short fork 2321, a spring piece slider 233, a long ejector rod 234, and a small magnet 235. At the rear end of the outer swing arm 231, there is a special-shaped joint same as the special-shaped joint of the connecting arm 221. The special-shaped joint of the outer swing arm 231 is inserted into the first through hole 212 and connected to the bottom beam 21 through a shaft, and the outer swing arm 231 can swing around the shaft within a certain range outwards. At the front end of the outer swing arm 231, there is a chuck 232 integrally and vertically connected thereto. The chuck 232 is connected to the outer swing arm 231 at the middle position. The right end is a semi-circular vertical surface, and the left end is provided with a short fork 2321. The fork opening of the short fork 2321 is on the left end vertical surface of the chuck 232. Inside the upper and lower wings of the fork, there are symmetrically arranged and through-axis holes and shafts matching the axis holes. At the middle position of the front vertical surface of the chuck 232, a spring piece slider 233 is connected by welding. The spring piece slider 233 is provided with a base and a special-shaped spring piece. The rear end of the base is at the middle position of the front vertical surface of the chuck 232, and the front end is inclined 45° to the left front. The special-shaped spring piece is transitioned by a semi-circular and a circular arc long side. The semi-circular end is fixed to the base with a screw, and the end of the circular arc long side is lapped at the middle position of the right semi-circular vertical surface of the chuck 232. The special-shaped spring piece and the chuck 232 are arranged in an L shape. The leftmost vertical surface of the semi-circular end exceeds the left end of the chuck 232 in the direction perpendicular to the bottom beam 21. The rightmost vertical surface of the circular arc long side exceeds the right end of the chuck 232 in the direction perpendicular to the bottom beam 21. The junction of the semi-circular and circular arc long sides is flush with the left end of the chuck 232 in the direction perpendicular to the bottom beam 21.

[0030] Between the special-shaped joint and the chuck 232 of the outer swing arm 231, there is a rectangular long ejector rod hole 2311 penetrating the left and right vertical surfaces. Near the side of the long ejector rod hole 2311 close to the special-shaped joint, there are symmetrically arranged and through-axis holes and shafts matching the axis holes between the outer swing arm 231 and the long ejector rod hole 2311. The front end of the left vertical surface of the long ejector rod 234 is a circular arc vertical surface, and the rear end vertical surface is an inclined surface with the left end lower and the right end higher. The long ejector rod 234 is provided with a protruding part protruding from the left vertical surface. The protruding part is provided with an axis hole matching the axis hole and shaft of the long ejector rod hole 2311. After connecting with the outer swing arm 231 through the axis hole of the protruding part, the long ejector rod hole 2311 can rotate around the axis within a certain range. When the circular arc vertical surface at the front end is flush with the left vertical surface of the connecting arm 221 under the push of an external force, the rear end abuts against the inner vertical surface of the bottom beam 21, so that the push-lock arm 23 can no longer swing and expand outwards around the axis, forming a limit lock for the push-lock arm 23.

[0031] The small magnet 235 is adhesively attached to the upper plane of the long ejector rod 234 and magnetically adsorbs to the left vertical surface of the outer swing arm 231. When the long ejector rod 234 is in a static state without external force, the front end of it is stably located behind the inner side of the right end of the chuck 232, without obstructing the incoming secondary support feet; the rear end is stably located at a position where it does not touch the thrust device 24. When the outer swing arm swings and expands outward around the axis, the rear end of the long ejector rod 234 is not blocked by the inner vertical surface of the bottom beam 21 and is inserted into the long fork opening 211 without obstruction, without restricting the outward swing and expansion of the outer swing arm 231. When the circular arc vertical surface at the front end of the long ejector rod 234 is pushed and squeezed by an external force, the small magnet 235 disengages from the left vertical surface of the outer swing arm 231 and loses its limiting and positioning effect on the long ejector rod 234; when the circular arc vertical surface at the front end of the long ejector rod 234 is flush with the right vertical surface of the connecting arm 221, the rear end of the long ejector rod 234 abuts against the inner vertical surface of the bottom beam 21;

[0032] The thrust device 24 includes a thick hollow tube 241, a retaining piece 2411, a thin hollow tube 242, a limiting piece 2421, and a thrust spring 243; the rear end of the thick hollow tube 241 is provided with a through hole matching the axis and the shaft hole of the large fork opening 211, and a retaining piece 2411 is provided at the front end of the through hole. The retaining piece 2411 is fixedly connected to the thick hollow tube 241 by welding; the front end of the thin hollow tube 242 is provided with a through hole matching the axis and the shaft hole of the short fork opening 2321, and a limiting piece 2421 is provided behind the through hole. The limiting piece 2421 is fixedly connected to the thin hollow tube 242 by welding; the retaining piece 2411 and the limiting piece 2421 are used to limit the front and rear ends of the thrust spring 243 to make it exert a thrust.

[0033] The thrust spring 243 is sleeved on the thick hollow tube 241 from the front end of the thick hollow tube 241, and the end abuts against the retaining piece 2411. The rear end of the thin hollow tube 242 passes through the spring 243 and is inserted into the thick hollow tube 241, and the limiting piece 2421 abuts against the thrust spring 243; the through hole at the rear end of the thick hollow tube 241 is connected to the bottom beam 21 through the shaft hole and the shaft of the long fork opening 211, and the through hole at the front end of the thin hollow tube 242 is connected to the bottom beam 21 through the shaft and the shaft hole of the short fork opening 2321, so that the thrust device 24 generates a thrust on the outer swing arm 231.

[0034] Let the assembly thrust of the elastic floor module 1 be A, the rebound thrust generated by the elastic piece slider 233 under the impact and extrusion of an external force be W, the thrust of the thrust device 24 be X, the magnetic attraction of the small magnet 235 be Y, and the rotational frictional resistance of the long ejector rod 234 around the axis be Z. The magnitude relationship of the five forces is: A > W > X > Y > Z.

[0035] When the elastic slide 233 is impacted, squeezed, and pushed by external forces from the front and right on its arc-shaped long side, the resulting rebound force or elastic thrust force is greater than the thrust force exerted by the thrust device 24 on the push-lock arm 23. Therefore, it drives and forces the push-lock arm 23 to swing axially outward and expand to relieve force around the first through-hole 212; when the external force acting on the elastic slide 233 disappears and the reset hindrance of the push-lock arm 23 disappears, the thrust force of the thrust device 24 pushes the push-lock arm 23 to quickly return to its original position; because the thrust force of the thrust spring 243 is greater than the magnetic attraction force of the small magnet 235 on the outer swing arm 231, when the arc-shaped vertical surface at the front end of the long push rod 234 is pushed and squeezed by an external force and the small magnet 235 disengages from the left vertical surface of the outer swing arm 231, it does not affect the reset action of the push-lock arm 23 and its subsequent static state after reset.

[0036] When the small magnet 235 disengages from the left vertical surface of the outer swing arm 231 and loses its positioning effect on the long push rod 234; when the arc-shaped vertical surface at the front end of the long push rod 234 is flush with the right vertical surface of the connecting arm 221 under the action of an external force, the rear end also abuts against the inner vertical surface of the bottom beam 21, forming a limit and positioning for the push-lock arm 23, so that the push-lock arm 23 can no longer expand and swing outward due to any external force.

[0037] Multiple elastic floor modules 1 are assembled horizontally in the front-back and left-right directions along the edge of the panel 10: the tenon at the front edge of the front end of the first elastic floor module 1 and below the panel 10 is inserted into the mortise at the rear edge of the second elastic floor module 1 and below the panel 10; the mortise at the left edge of the third elastic floor module 1 and below the panel 10 simultaneously sleeves the tenons at the right edges of the first elastic floor module 1 and the second elastic floor module 1.

[0038] The front support feet 13 of the first elastic floor module 1 and the rear support feet 17 of the second elastic floor module 1 form a docking support foot with the same outer dimension as the main support foot 11, and the front limit groove 131 and the rear limit groove 171 also form a limit arm receiving cavity for accommodating the limit arm 222.

[0039] The right front support feet 14 of the first elastic floor module 1 and the right rear support feet 16 of the second elastic floor module 1 form a docking support foot with the same outer dimension as the right support foot 15.

[0040] The left front support feet 12 of the first elastic floor module 1 and the left rear support feet 18 of the second elastic floor module 1 form a docking support foot with the same outer dimension as the left support foot 19.

[0041] The left support feet 19 of the first elastic floor module 1 and the right support feet 15 of the third elastic floor module 1 form a docking support foot with the same size as the main support foot 11, and the left limit groove 191 and the right limit groove 151 also form a limit arm receiving cavity for accommodating the limit arm 222.

[0042] The left support foot 19 of the third elastic floor module 1, together with the right front support foot 14 of the first elastic floor module 1 and the right rear support foot 16 of the second elastic floor module 1, form a docking support foot of the same size as the main support foot 11; the left limiting groove 191 and the right front limiting groove 141 also form a limiting arm receiving cavity for receiving the limiting arm 222;

[0043] Multiple floor modules 1 are assembled horizontally in the left-right and front-back directions along the edge of the panel 10: the mortise groove below the right edge of the first elastic floor module 1 and below the panel 10 sleeves the tenon tongue below the left edge of the second elastic floor module 1 and below the panel 10; the mortise grooves below the left edge and the rear edge of the third elastic floor module 1 and below the panel 10 sleeve the tenon tongues on the right edge of the first elastic floor module 1 and the front edge of the third elastic floor module 1 at the same time;

[0044] The right support foot 15 of the first elastic floor module 1, together with the left support foot 19 of the second elastic floor module 1, form a docking support foot of the same size as the main support foot 11, and the left limiting groove 191 and the right limiting groove 151 also form a limiting arm receiving cavity for receiving the limiting arm 222;

[0045] The left support foot 19 of the first elastic floor module 1, the left front support foot 12 of the second elastic floor module 1, and the left rear support foot 18 of the third elastic floor module 1 form a docking support foot with the same external dimensions as the main support foot 11, and the left limiting groove 191 and the left front limiting groove 121 also form a limiting arm receiving cavity for receiving the limiting arm 222;

[0046] Installation and application of the locking connector 2 on the elastic floor module 1; install the locking connector 2 on the front support foot 13 and the right support foot 15, and do not install the locking connector 2 on other support feet; erect the elastic floor module 1, place the self-locking arm 22 of the locking connector 2 on one side of the limit groove 131, and the positioning pin 214 on one side of the positioning hole 132. Pull the push-locking arm 23 and the self-locking arm 22 to expand outwards so that the front support foot 13 is between the push-locking arm 23 and the self-locking arm 22. At the same time, insert the positioning pin 214 into the front positioning hole 132, and the bottom beam 21 fits against the rear vertical surface of the front support foot 13. Then release the push-locking arm 23 and press the self-locking arm 22 so that the limit arm 222 is completely fitted into the limit groove 131; during the process of the limit arm 222 being fitted into 131, the distance between the connecting arm 221 and the right vertical surface of the front support foot 13 gradually becomes smaller. The front end arc-shaped vertical surface of the ejector rod 223 is squeezed by the right vertical surface of the front support foot 13, and drives the rear end of the ejector rod 223 to displace leftward around the axis. When the limit arm 222 is completely fitted into the limit groove 131, the front end arc-shaped vertical surface of the ejector rod 223 is flush with the left vertical surface of the connecting arm 221 and simultaneously abuts against the right vertical surface of the support foot 13. The rear end of the ejector rod 223 also abuts against the inner vertical surface of the bottom beam 21, forming a positioning lock on the self-locking arm 22, so that it can no longer swing or expand outwards around the axis due to any external force, forming a clamping on the front support foot 13;

[0047] Further, the rear end of the ejector rod 223 abuts against the bottom beam 21, also forming a positioning lock on the bottom beam 21, and further forming the positioning and fixing of the locking connector 2 on the front support foot 13; unless the bottom beam 21 slides to the right along the rear vertical surface of the front support foot 13, it will cause the self-locking arm 22 to displace and loosen, losing the self-locking function, resulting in the locking connector 2 falling off the front support foot 13;

[0048] Further, the positioning pin 214 in the front positioning hole 132 restricts the bottom beam 21, so that the bottom beam 21, which cannot rotate around the axis backward and fit against the rear vertical surface of the front support foot 13 under the restriction of the self-locking arm 22, cannot displace in any direction on the rear vertical surface of the front support foot 13;

[0049] Further, under the combined action of the locking and positioning of the self-locking arm 22 and the positioning pin 214, the locking connector 2 firmly holds the front support foot 13. At this time, unless the front support foot 13 or the locking connector 2 is violently damaged, the locking connector 2 will not be affected by the oblique rear and backward acting forces generated by the impact and extrusion of the elastic slider 233 at the front end of the push-locking arm 23 when assembling and docking with other support feet, causing the position of the bottom beam 21 to change, driving the self-locking arm 22 to lose the self-locking function, and then causing the locking connector 2 to loosen, fall off and fail;

[0050] Further, at this time, the left front arc-shaped vertical surface of the long ejector rod 234 is not touched or displaced by external force. Therefore, under the magnetic attraction limit of the small magnet 235, the long ejector rod 234 does not restrict the outward swing and expansion of the push-locking arm 23.

[0051] Take the locking device 2 and install it on the right supporting foot 15; place the self-locking arm 22 on the side of the right limit groove 151, and the positioning pin 214 on the side of the positioning hole 152. At the same time, pull the push-lock arm 23 and the self-locking arm 22 to expand outward so that the right supporting foot 15 is between the push-lock arm 23 and the self-locking arm 22, insert the positioning pin 214 into the front positioning hole 152, and the bottom beam 21 fits the left vertical surface of the right supporting foot 15. Release the push-lock arm 23 and press the self-locking arm 22 to make the limit arm 222 completely fit into the limit groove 151.

[0052] Further, the locking connector 2 is installed on the right front supporting foot 14 and the right rear supporting foot 16 after docking; when the elastic floor module 1 is assembled on the site, the first route is assembled in the order of front and rear docking assembly. After the first route is assembled, the second route is assembled on the right side of the first route, and the third route is assembled on the right side of the second route, and the entire site is paved by assembling routes from right to left; to assemble the first route of elastic floor modules 1, first take the first elastic floor module 1 with the locking connector 2 installed, place it at the designated position at the beginning of the first route, lift the second elastic floor module 1 and place its rear supporting foot 17 on the right side of the front supporting foot 13 of the first elastic floor module 1, first push the second elastic floor module 1 backwards, insert the mortise and tenon at the rear end of the second elastic floor module 1 into the mortise and tenon of the first elastic floor module 1, and then push the second elastic floor module 1 to the right to align the left and right edges of the two elastic floor modules 1; the rear limiting groove 171 of the second elastic floor module 1 runs through the entire During the alignment process, the rear limit groove 171 of the second elastic floor module 1 fits the limit arm 222 exposed on the outer facade of the front support foot 13 of the second elastic floor module 1; when the left side facade of the rear support foot 17 of the second elastic floor module 1 enters the inner side of the clamping head 232 of the locking connector 2 on the front support foot 13 of the first elastic floor module 1, it contacts and squeezes the front end arc facade of the long push rod 234 to the right, so that the small magnet 235 is moved from the outer swing arm 231. The left side elevation is disengaged, and the positioning function of the long push rod 234 is lost. The front end of the long push rod 234 moves to the right until the front end elevation of the long push rod 234 is flush with the right side elevation of the outer swing arm 231 and is close to the front end elevation of the left support foot 19. At this time, the rear end also contacts the inner side elevation of the bottom beam 21, and the push lock arm 23 is locked to prevent it from swinging outward around the axis and expanding. It always holds the front support foot 13 and the rear support foot 17 after docking to prevent the two from detaching and displacing in the front and rear directions.

[0053] The right rear support foot 16 of the second elastic floor module 1 is also docked with the right front support foot 14 of the first elastic floor module 1. Take the locking connector 2 and place the self-locking arm 22 on one side of the right front limit groove 141 and the positioning pin 214 on one side of the right rear positioning hole 161. Place the locking connector 2 behind the inner sides of the right rear and right front docking support feet through the space between the arched support and the ground. Pull the push-lock arm 23 and the self-locking arm 22 to expand outwards, so that the docking support feet formed by the right rear and right front support feet are between the push-lock arm 23 and the self-locking arm 22. Insert the positioning pin 214 into the right rear positioning hole 161, and the bottom beam 21 fits against the inner vertical surfaces of the right rear and right front support feet. Release the push-lock arm 23 and press the self-locking arm 22 to make it fully fit into the right front limit groove 141, completing the installation and connection locking of the locking connector 2 on the right rear and right front docking support feet, and waiting for the docking of the next elastic floor module 1 at the front end and the docking of the second row of elastic floor modules 1 on the right side;

[0054] Through the connection, locking and fixing of the front support feet 13 and the rear support feet 17, the right rear support feet 16 and the right front support feet 14 by the locking connector 2, the connection and locking of the first elastic floor module 1 and the second elastic floor module 1 in the front-rear direction are completed;

[0055] According to the assembly method of the second elastic floor module 1 in the first row, complete the assembly of the elastic floor modules 1 in the first row.

[0056] Further, install the second row of elastic floor modules 1; place the first elastic floor module 1 in the second row on the right side of the elastic floor module 1 in the first row, and stagger the front edge of the front end from the front edge of the first one in the first row for staggered joint assembly, and linearly cut off the part that exceeds the rear edge of the first one in the first row at the rear end;

[0057] Lift the first elastic floor module 1 that has been cut and installed with the locking connector 2, place its left support foot on the right side of the elastic slide head 233 of the locking connector 2 on the right side of the elastic floor module 1 in the first row without touching the elastic slide head 233, and push it to the left so that its left mortise groove fits the right tenon of the elastic floor module 1 in the first row, and each left support foot is stuck into the corresponding locking connector 2 to complete their respective docking;

[0058] Further, for the locking connector 2 on the right side of the elastic floor module 1 in the first row, the elastic slide head 233 at the front end of the push-lock arm 23 is impacted and squeezed by the edge of the left support foot 19 of the second row of elastic floor modules 1, generating an outward oblique force on the circular arc inclined surface of the elastic slide head 233, forcing and driving the push-lock arm 23 to swing and expand outwards around the axis at the first through hole 212, quickly opening the docking channel between the right support foot 15 and the left support foot 19. The front corner of the right support foot 15 slides past the corners of the elastic slide head 233 and the chuck 232 and then completes the docking with the left support foot 19, and the left limit groove 191 of the left support foot 19 fits the part of the limit arm 222 exposed outside the right limit groove 151;

[0059] Meanwhile, the reset obstruction of the push-lock arm 23 disappears, and it quickly resets under the thrust of the thrust device 24. The inner vertical surface fits the front vertical surfaces of the right support foot 15 and the left support foot 19, and the rear vertical surface of the chuck 232 fits the right vertical surface of the left support foot 19. During the reset process of the push-lock arm 23, the front vertical surface of the long ejector rod 234 is displaced to the left due to the extrusion of the front vertical surface of the left support foot 19, causing the small magnet 235 to disengage from the left vertical surface of the swing arm 231 and losing its positioning effect on the long ejector rod 234. When the reset of the push-lock arm 23 is completed, the front vertical surface of the long ejector rod 234 is flush with the inner vertical surface of the swing arm 231 and simultaneously presses against the front vertical surface of the left support foot 19, and the rear end touches the inner vertical surface of the bottom beam 21, forming a positioning lock on the push-lock arm 23, preventing it from swinging or expanding out of the axis, and always tightly holding the butted right support foot 15 and left support foot 19 to prevent them from disengaging and displacing in the left-right direction.

[0060] The lock connector 2 completes the connection and locking of the first-way elastic floor module 1 and the first elastic floor module 1 of the second way in the left-right direction through the right support foot 15 and the left support foot 19.

[0061] The left front support foot 12 of the first elastic floor module 1 is butted against the right support foot 15 of the first-way elastic floor module 1, and the left front limit groove 121 fits the limit arm 222 exposed outside the right limit groove 151. At this time, for the lock connector 2 on the right support foot 15 of the first-way elastic floor module 1, its push-lock arm 23 is not in the locked state and waits for the docking of the left rear support foot 18 of the next elastic floor module 1.

[0062] Further, install the second elastic floor module 1 of the second way; lift the second elastic floor module 1 with the installed lock connector 2, place its left support foot on the right side of the elastic slide head 233 of the lock connector 2 on the right side of the first-way elastic floor module 1 without touching the elastic slide head 233, and place the rear support foot on the right side of the front support foot 13 of the first elastic floor module 1 of the second way. Then push the second elastic floor module 1 backward so that its rear mortise fits the front tenon tongue of the first elastic floor module 1, and then push it to the left so that its left mortise fits the right tenon tongue of the first-way elastic floor module 1, and the left edges of each support foot are snapped into the corresponding lock connector 2 to complete the docking.

[0063] According to the assembly method of the second elastic floor module 1 of the second way, complete the assembly of the second-way elastic floor module 1;

[0064] According to the assembly method of the second-way elastic floor module 1, complete the assembly of the third-way elastic floor module 1;

[0065] Assemble the fourth way on the right side of the third way, and assemble the fifth way on the right side of the fourth way until the assembly of the entire site is completed.

[0066] The locking connector 2 completes the connection and locking in the left - right direction of the first - row elastic floor modules 1 and the second - row elastic floor modules 1 by connecting and locking the docking support feet composed of the right support foot 15 and the left support foot 19, the right support foot 15 and the left front support foot 12, the left rear support foot 18, the right rear support foot 16, the right front support foot 14 and the left support foot 19;

[0067] The locking connector 2 is produced, assembled and batch - packaged in the factory, and transported to the construction site together with the elastic floor module 1.

[0068] Another object of the embodiment of the present application is to provide an installation method for an indoor - outdoor universal assembled nail - free sports wooden floor. The installation method includes the following steps:

[0069] S1. Prepare the required tools, equipment and materials;

[0070] Tools and equipment: There are 2 people in an installation team, and each team is equipped with two handheld lithium - battery cutting machines, two rubber hammers and two tape measures;

[0072] S2. Complete the installation of the first - row elastic floor modules 1 of the site in the order from front to back; on the right side of the first - row elastic floor modules 1, dock and assemble the second - row elastic floor modules 1. The front edge of the first elastic floor module 1 in the second row is staggered from that of the first elastic floor module 1 in the first row for staggered joint assembly. Use a handheld lithium - battery cutting saw for cutting if necessary; when assembling, if necessary, use a rubber hammer to tap the front end and the left side of the elastic floor module 1 to adjust it in place; install the third, fourth, etc. in the same way as the second one until the assembly of the second - row elastic floor modules 1 is completed; dock and assemble the third row on the right side of the second row in the same way as the second row; install the fourth row on the right side of the third row; complete the installation of the entire site according to this installation sequence;

[0073] S3. Clean the floor surface and paint or lay a non - slip and wear - resistant layer; if the paint or non - slip and wear - resistant layer has been applied in the factory by pushing lines, this process is not required;

[0075] In S2, for the indoor venue, there is no need to place construction lines. Place the first floor module 1 of the first row on the ground at any one of the four corners of the venue. The left edge and the rear edge are respectively close to the walls on both sides of the corner, and a certain gap is reserved between the two walls to prevent the elastic floor module 1 from rubbing against the walls. For the outdoor open-air venue, if there is a sports fence, place the first floor module 1 of the first row on the base ground at any one of the four corners of the venue. The left edge and the rear edge are respectively close to the fence columns on both sides of the corner of the venue, and a certain gap is reserved between the two fence columns to prevent the floor module 1 from rubbing against the fence columns. For the outdoor open-air venue without a sports fence, it is necessary to place the boundary lines of the sports venue in advance. Place the first elastic floor module 1 of the first row on the base ground at any one of the four corners of the venue, and the left edge and the rear edge are respectively aligned with the boundary lines on both sides of the corner of the venue.

[0076] With the reasonable settings of the support feet, limit slots, and positioning holes in this application, the locking connector 2 realizes the connection, limitation, locking, and fixation of adjacent elastic floor modules 1 by connecting, limiting, locking, and fixing each support foot, ensuring the large-area paving of this application.

[0097] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way serves as a limitation to the present application and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below. The following is a detailed description of the specific implementation of the present application with reference to the accompanying drawings and specific embodiments. Embodiment

[0098] As Figures 1 to 15 shown, an indoor and outdoor universal assembled nail-free sports wooden floor is provided for an embodiment of the present application, including an elastic floor module 1 and a lock connector 2. A plurality of support feet are provided at the lower end of the elastic floor module 1. The lock connector 2 realizes the permanent connection, limitation, locking and fixing of adjacent elastic floor modules 1 by permanently connecting, limiting, locking and fixing adjacent support feet, and the large-area assembly and paving of the elastic floor module 1, forming a large plane required for sports and fitness.

[0099] As Figures 2 to 5As shown, the elastic floor module 1 consists of two parts: the floor module and the elastic rubber pad. The floor module is a wood-plastic product made of polymer composite materials, which is environmentally friendly, non-toxic, and friendly to human health and the ecological environment. As a ductile and elastic material, it has the advantages of strong plasticity, pressure resistance, impact resistance, resistance to high and low temperatures, resistance to moisture and water immersion, and long service life. As a product form of wood-plastic in polymer composite materials, wood-plastic floors are widely used. At the same time, they can also prevent insects and termites. Therefore, wood-plastic floors can be used in complex environments where traditional solid wood products cannot be used.

[0100] Compared with the products with simple structural shapes such as ribbon-shaped narrow strips produced by extrusion production, the advantages of using the plasticity of plastic materials for compression molding production are: good repeatability, simple operation, and the product quality is not affected by the operator and external conditions; the product molding cycle is short, complex structures are formed in one step, the dimensions of the pressed products are accurate, the surface of the pressed products is smooth and more convenient for surface treatment, the high-intensity pressure makes the quality density of the pressed products larger and stronger, the stability of the products is better, the thermal expansion and contraction rate is low, the anti-bending and anti-compression capabilities are stronger, the load-bearing capacity is better, and the comprehensive cost of the materials is lower.

[0101] As Figures 2 to 5 As shown, the elastic floor module 1 includes a floor module and an elastic rubber pad. The upper end of the floor module is provided with a panel 10, and the upper surface of the panel 10 is the use surface of this application for sports and fitness activities. At the lower end of the floor module and the back of the panel, there are multiple main support feet 11 and multiple secondary support feet. The multiple secondary support feet include a left front support foot 12, a front support foot 13, a right front support foot 14, a right support foot 15, a right rear support foot 16, a rear support foot 17, a left rear support foot 18, and a left support foot 19.

[0102] The bottom surface of the main support foot 11 is provided with four square protrusions, and the bottom surfaces of the front support foot 13, the rear support foot 17, the left support foot 19, and the right support foot 15 are each provided with two square protrusions. The bottom surfaces of the left front support foot 12, the left rear support foot 18, the right front support foot 14, and the right rear support foot 16 are each provided with a single square protrusion.

[0103] Elastic rubber pads are provided in a matching manner under the main support foot and each secondary support foot. The upper planes of the respective matching elastic rubber pads are provided with square recesses corresponding to the square protrusions. Each support foot and its respective matching elastic rubber pad are connected by an adhesive method, and the square protrusions are inserted into the square recesses. The purpose of setting the square protrusions and square recesses is to increase the contact area between the support feet and the elastic rubber pads, thereby increasing the firmness of the adhesion. Moreover, with the connection of the square protrusions and square recesses, it can be ensured that when the elastic floor module 1 is pushed and assembled, the elastic rubber pad is prevented from rotating and other position changes on the bottom surface of the support feet due to the ground friction resistance, which affects the docking of the secondary support feet.

[0104] As Figures 2 to 5 、Figures 12 to 15 As shown in the figure, the front support feet 13 are provided with front limit grooves 131 and front positioning holes 132, the rear support feet 17 are provided with rear limit grooves 171, the left front support feet 12 are provided with left front limit grooves 121, the right front support feet 14 are provided with right front limit grooves 141, and the right rear support feet 16 are provided with right rear positioning holes 161; multiple elastic floor modules 1 are butt-jointed in the front-back horizontal direction. The front support feet 13 and the rear support feet 17 form butt-joint support feet with the same external dimension as the main support feet 11. The front limit grooves 131 and the rear limit grooves 171 form a limit arm accommodation cavity for accommodating the limit arms 222; the left front support feet 12 and the left rear support feet 18 form butt-joint support feet with the same size as the left support feet 19; the right front support feet 14 and the right rear support feet 16 form butt-joint support feet with the same size as the right support feet 15;

[0105] The right support feet 15 are provided with right limit grooves 151 and right positioning holes 152, and the left support feet 19 are provided with left limit grooves 191; multiple elastic floor modules 1 are butt-jointed in the left-right horizontal direction. The right support feet 15 and the left support feet 19 form butt-joint support feet with the same external dimension as the main support feet 11. The right limit grooves 151 and the left limit grooves 191 form a limit arm accommodation cavity for accommodating the limit arms 222;

[0106] The right support feet 15, the left front support feet 12 and the left rear support feet 18 form butt-joint support feet with the same external dimension as the main support feet 11. The right limit grooves 151 and the left front limit grooves 121 form a limit arm accommodation cavity for accommodating the limit arms 222; the left support feet 19, the right front support feet 14 and the right rear support feet 16 form butt-joint support feet with the same external dimension as the main support feet 11. The left limit grooves 191 and the right front limit grooves 141 form a limit arm accommodation cavity for accommodating the limit arms 222;

[0107] The difference between the rear limit groove 171 and other limit grooves is that it penetrates the rear vertical surface of the entire rear support foot 17 and its length is twice that of other limit grooves; the purpose is to eliminate the obstructive influence of the limit arms 222 on the right push when multiple elastic floor modules 1 are assembled and butted and need to be pushed to the right.

[0108] Through the above settings of the secondary support feet, limit grooves and positioning holes, it is ensured that after multiple elastic floor modules 1 are assembled in the front-back and left-right horizontal directions, as a single-size coupler 2, it is installed on each secondary support foot and butt-joint support foot through the limit grooves and positioning holes. When multiple elastic floor modules 1 are assembled, the secondary support feet located below the edges of multiple elastic floor modules 1 are connected, limited, locked and fixed, thereby realizing the connection, limitation, locking and fixation of the coupler 2 to multiple elastic floor modules 1 as individual units, so that the present application obtains a large-area floor site required for sports.

[0109] Such as Figures 2 to 5As shown in the figure, below the edge of the panel 10, there are matching tenons and mortises. The tenons and mortises are arranged below the edge of the panel 10 without damaging the strength of the edge of the panel 10. After multiple elastic floor modules 1 are spliced horizontally in the front-back, left-right directions, the tenons and mortises that are sleeved and inserted make the adjacent elastic floor modules 1 restrict and support each other, enhancing the integrity after large-area paving of multiple elastic floor modules 1. The difference between the upper and lower thickness of the tenon and the upper and lower width of the mortise is ≤0.2mm. Under the influence of external environmental factors such as high temperature, low temperature, air humidity, and seasonal climate changes, the tenons and mortises that are sleeved and inserted have a margin space for contraction and expansion, and to avoid that when the tenons and mortises that are sleeved and inserted first in the front-back direction during the splicing of multiple elastic floor modules 1 are too tightly engaged, resulting in the elastic floor module 1 being unable to be pushed to the right or being difficult to push to the right, ensuring the smooth and unobstructed assembly of multiple elastic floor modules 1.

[0110] Further, when athletes walk, run, jump, and step on the upper surface of the panel 10 of two adjacent elastic floor modules 1 after being assembled in the front-back and left-right directions, when the sole of the foot generates downward gravity and impact force at the edge of the adjacent panel 10, due to the mutual limiting and restricting effects of the tenon and mortise joints for support, they jointly disperse and bear the gravity and impact force transmitted to the edge of the panel 10, avoiding any one edge alone bearing the gravity and impact force, resulting in different instantaneous deformations and tremor frequencies, ensuring that the edges of the adjacent panels 10 of the adjacent elastic floor modules 1 assembled and docked in the front-back, left-right directions, the horizontal degrees, instantaneous deformations, and tremor frequencies of the upper surfaces of the floors on both sides of the edges of the adjacent panels 10 are always in the same state, avoiding that during intense competitive sports of athletes, due to the different horizontal heights of the edges of the adjacent panels 10 of the adjacent elastic floor modules 1 and the upper surfaces of the floors on both sides of the edges of the adjacent panels 10, the soles of the shoes collide, endangering personal safety, and different instantaneous deformations and tremor frequencies affecting the technical performance.

[0111] As Figure 4 、 Figure 5 As shown in the figure, on the back of the panel 10, there are arched supports between each support foot, and a cross-shaped layout of strengthening supports that are vertically and intersectingly connected to each arched support; when athletes walk, run, jump, and step on the upper surface of the panel 10 of the elastic floor module 1, when the sole of the foot generates downward gravity and impact force between the parallel arched supports, in addition to the panel 10 directly dispersing to the surroundings, it is also directly conducted by the strengthening supports to each arched support that they are vertically and intersectingly connected to, avoiding long-term gravity impact resulting in collapse and deformation between the parallel arched supports; and quickly feedback the shock absorption, rebound and other reaction forces from the elastic rubber pad to the upper surface of the panel 10 between the adjacent parallel arched supports; avoiding different shock absorption effects and rebound strengths at the positions on the upper surface of the panel 10 of the floor module 1 where there are arched supports and where there are no arched supports below, promoting the uniform display of the elastic and shock-absorbing physical and mechanical properties of the floor module 1.

[0112] The mutual gain between the arch supports connecting the supporting feet and the reinforcing supports arranged in a tic-tac-toe pattern and perpendicularly intersecting the arch supports enhances the integrated strength of the elastic floor module 1 and strengthens the overall load-bearing performance, impact resistance and deformation resistance of the elastic floor module 1.

[0113] As a benefit measure of the present application: steel bars are built into the arch supports connecting the supporting feet and the reinforcing supports in a tic-tac-toe layout that are perpendicular to and connected to the arch supports, so as to further enhance and strengthen the longitudinal and lateral deformation resistance of the elastic floor module 1 and enhance the seismic resistance and tensile strength of the elastic floor module 1; before the floor module of the elastic floor module 1 is molded, the steel bars are placed at the corresponding positions of the designated parts in the special molding mold for the floor module, and the steel bars can be built in through normal molding production.

[0114] like Figure 6 , Figure 7 As shown, the locking device 2 includes a bottom beam 21, a self-locking arm 22, a push-locking arm 23, and a thrust device 24; the self-locking arm 22 and the push-locking arm 23 are connected to the bottom beam 21 through the axis of the first through hole 212 and the second through hole 213 provided on the bottom beam 21; one end of the thrust device 24 is connected to the bottom beam 21 through the axis of the long fork 211 at the left end of the bottom beam 21, and the other end is connected to the push-locking arm 23 through the axis of the short fork 2321, and is connected to the bottom beam 21 through the axis of the bottom beam 21. The limit exerts an elastic thrust toward the push-lock arm 23; the first through hole 212 and the second through hole 213 pass through the bottom beam 21, and open at the inner upper and lower corners of the bottom beam 21, forming a ┫ shape; the ┫-shaped opening setting ensures that after the bottom beam 21 is connected with the self-locking arm 22 and the push-lock arm 23, it does not conflict with the rear ends of the self-locking arm 22 and the push-lock arm 23, thereby preventing the self-locking arm 22 and the push-lock arm 23 from being unable to expand outward around the axis due to the conflict limitation of the bottom beam 21.

[0115] like Figure 7 As shown in the figure, the rear end ends of the self-locking arm 22 and the push-locking arm 23 are both provided with a semi-elliptical special-shaped joint, so as to avoid the special-shaped joint generating friction resistance with the bottom beam 21 in the ┫-shaped through hole when the self-locking arm 22 and the push-locking arm 23 expand outward around the axis, so that the self-locking arm 22 and the push-locking arm 23 can expand outward around the axis more smoothly; the self-locking arm 22 and the push-locking arm 23 are both provided with oblique corners at the outer corners of the connection with the special-shaped joint to the upper plane of the special-shaped joint. Compared with the right angle, the oblique corner The corners increase the oblique distance from the ┫-shaped through hole, so that the self-locking arm 22 and the push-locking arm 23 can obtain a larger expansion range when expanding outward around the axis; the combination of the ┫-shaped through hole, the special-shaped joint, and the oblique corners enables the self-locking arm 22 and the push-locking arm 23 to achieve unobstructed and sufficient expansion space around the axis, ensuring that the locking device 2 can be easily installed on each secondary supporting foot and realize smooth docking with other secondary supporting feet, thereby playing an important role in connecting adjacent elastic floor modules 1.

[0116] likeFigure 6 , Figure 7 As shown in Figure 7 , for the limiting arm 222 of the self-locking arm 22, the upper and lower outer corners at the front end and the outer corner at the left end are set as inclined planes, which is beneficial to reducing corner bumps when each limiting groove is butted and sleeved with the limiting arm 222.

[0117] Furthermore, after the athlete walks, runs, jumps, and tramples on the upper surface of the panel 10 of two adjacent elastic floor modules 1 assembled in the front-back and left-right directions, when the sole of the foot generates downward gravity and impact force at the edge of the adjacent panel 10, the limiting arm 222 in the limiting arm accommodation cavity, due to the limitation of the limiting groove, forms a common limiting restriction on the adjacent elastic floor modules 1 with the tenon and mortise grooves sleeved and inserted with each other at the lower edge of the panel 10, further enhancing the long-term stability after large-area paving of this application.

[0118] For the ejector rod 223 of the self-locking arm 22 and the long ejector rod 234 of the push-lock arm 2, the vertical surfaces at the front ends facing the inside are all arc-shaped vertical surfaces. When installing the lock connector 2, when the arc-shaped vertical surface contacts and is squeezed by the vertical surface of the support foot, it can slide and displace on the vertical surface of the support foot with extremely small frictional resistance, enabling the ejector rod to smoothly rotate around the axis in the ejector rod hole, driving the rear end to abut against the inner vertical surface of the bottom beam 21, and quickly realizing the limiting and locking of the ejector rod to the self-locking arm 22 and the push-lock arm 23.

[0119] As Figures 8 to 15 shown in Figures 8 to 15 , the small magnet 235 provided on the long ejector rod 234 makes the front end of the long ejector rod 234 stably located on the left side of the right end of the chuck 232 in the direction perpendicular to the bottom beam 21 when it is in a static state without external force, without hindering the incoming secondary support foot; the rear end is stably located at a position where it does not touch the thrust device 24, ensuring that when the outer swing arm 231 swings and expands outward around the axis, the rear end of the long ejector rod 234 can be inserted into the long fork 211 without being blocked by the inner vertical surface of the bottom beam 21; since the ejector rod 223 does not need to be positioned due to the manual installation of the self-locking arm 22, the ejector rod 223 can rotate around the axis without hindrance before the lock connector 2 is installed on the secondary support foot, without restricting the outward expansion of the self-locking arm 22 around the axis; the setting of the ejector rod 223 enables the lock connector 2 to form a self-locking effect on the lock connector 2 by clamping the secondary support foot through the self-locking arm 22 after the lock connector 2 is installed on the secondary support foot, and then jointly forms a stable self-locking and positioning with the positioning pin 214.

[0120] As Figures 8 to 11 shown in Figures 8 to 11 , the positioning of the long ejector rod 234 by the small magnet 235 and the long fork 221 enable the push-lock arm 23 to swing and expand outward around the axis without being restricted by the long ejector rod 234 when the lock connector 2 accepts the docking of the secondary support foot, and after accepting the docking of the secondary support foot, under the thrust of the thrust device 24, the lock connector 2 completes the access and locking, and automatically locks and locks.

[0121] The vertical surface of the rear end of the ejector rod (223) is an inclined surface with a higher left side and a lower right side, and the vertical surface of the rear end of the long ejector rod (234) is an inclined surface with a lower left side and a higher right side, ensuring that the rear ends of the two ejector rods can smoothly move to the position where they contact the bottom beam 21.

[0122] As Figures 8 to 15 shown, the special-shaped spring piece of the spring piece slider 233 is arranged in an "フ" shape with the chuck 232, and is transitioned by a semi-circular and an arc-shaped long side, and the end of the arc-shaped long side is lapped at the middle position of the right semi-circular vertical surface of the chuck 232; the spring piece, as an elastic material, itself has the properties of bearing pressure and rapid rebound. The long side of the special-shaped spring piece transitioning to the right semi-circular vertical surface of the chuck 232 is set as an arc transition instead of a linear transition. Because after the arc is extruded and collided by the external force from the secondary support foot, it can better conduct the acting force to the outer swing arm 231 quickly and instantaneously rebound to release the elastic potential energy, forcing the outer swing arm 231 to swing and expand outward around the axis quickly, opening the docking channel of the secondary support foot and enabling the secondary support foot to complete the docking smoothly; the end of the arc-shaped long side is lapped at the middle position of the right semi-circular vertical surface of the chuck 232, and the lapping method is adopted instead of the fixed method. Because the arc-shaped long side of the special-shaped spring piece instantaneously deforms after being extruded and collided by the external force from the secondary support foot, changing from an arc to a straight line, and the length increases instantaneously. The lapping method does not hinder the instantaneous extension and expansion of the end of the arc-shaped long side on the semi-circular vertical surface of the chuck 232, and does not hinder the rapid retraction when rebounding back to the arc shape, which does not hinder the docking of the secondary support foot.

[0123] Furthermore, multiple elastic floor modules 1 are assembled in the horizontal directions of front, back, left, and right. When installing the second piece in the second row, first push it backward to make the front and back dock, and then push it leftward to make the left and right dock; after the front and back docking, the front vertical surface and the corners of the left secondary support foot that are about to move leftward for docking are on the same straight line in the left-right direction as the right vertical surface of the outer swing arm 231 of the locking connector 2 on the right secondary support foot; the leftmost vertical surface of the semi-circular end of the special-shaped spring piece extends beyond the left end of the chuck 232 in the direction perpendicular to the bottom beam 21; the junction of the semi-circular and the arc-shaped long sides is flush with the left end of the chuck 232 in the direction perpendicular to the bottom beam 21; these positions are set far beyond the right vertical surface of the outer swing arm 231, expanding the action range of the arc-shaped long side and thus increasing the access range of the left secondary support foot, ensuring that when there are limited position deviations during the docking of the left and right support feet, they can still be smoothly docked.

[0124] Furthermore, when the corner of the left secondary supporting foot contacts and collides with the arc-shaped long side of the spring slide 233 of the locking connector 2 on the right secondary supporting foot and continues to slide to the right along the rightmost vertical surface of the arc-shaped long side for docking, the rightmost vertical surface of the arc-shaped long side exceeds the right semicircular end of the clamp 232 in the direction perpendicular to the bottom beam 21, ensuring that the arc-shaped long side continuously feeds back the maximum elastic thrust to the external swing arm 231, while avoiding the delay of the right semicircular end of the clamp 232 in docking with the left secondary supporting foot, thereby sending the left secondary supporting foot into the docking position at a better angle.

[0125] Furthermore, the vertical surface where the long arc side contacts and collides with the corners of the secondary supporting foot is an obstacle-free plane, which can ensure that the corners of the secondary supporting foot can slide smoothly on the vertical surface of the long arc side, thereby successfully docking; the semicircular vertical surface on the right side of the clamping head 232 does not cause any obstruction or collision to the corners of the secondary supporting foot sliding from the long arc side, ensuring that the push-locking arm 23 is quickly reset and completes the clamping and locking of the secondary supporting foot at the moment when the reset obstacle caused by the secondary supporting foot disappears, so that the locking device 2 can realize the connection and locking of the docking supporting feet, and then realize the connection, limitation, locking and fixation of the adjacent elastic floor modules 1 by the locking device 2.

[0126] Assume that the assembly thrust of the elastic floor module 1 is A, the rebound thrust generated by the spring slider 233 under the impact, extrusion and push of the external force is W, the thrust of the thrust device 24 is X, the magnetic attraction of the small magnet 235 is Y, and the friction resistance of the long push rod 234 rotating around the axis is Z. The magnitude relationship of the five forces is: A>W>X>Y>Z; the force size setting ensures that the self-locking device 2 can smoothly complete the reception, connection, locking and fixation of the secondary supporting feet when each secondary supporting foot is docked.

[0127] like Figure 1 , Figures 6 to 15 As shown, after the lock connector 2 completes the connection and locking of the docking support foot, the rear end of the long push rod 234 is restricted by the contact between the bottom beam 21, so that the push lock arm 23 cannot expand or move outward in any way, and the inner side of the clamping head 232 firmly hugs the docking support foot, so that the adjacent elastic floor modules 1 cannot be separated and displaced in the front-to-back and left-to-right directions; the positioning pin 214 in the positioning hole prevents the bottom beam 21 from being displaced in the right-to-right direction, and the limiting arm accommodating cavity composed of the limiting groove clamps and constrains the limiting arm 222, and the rear end of the push rod 223 is restricted by the contact between the bottom beam 21, so that the self-locking arm 22 cannot expand or move outward in any way; the left side elevation of the limiting arm 222 in the limiting groove of the right secondary support foot is in conflict with the front side elevation of the limiting groove of the left secondary support foot, forming positioning and limiting for the adjacent elastic floor modules 1 assembled in the left and right horizontal directions, so that the adjacent elastic floor modules 1 assembled in the left and right horizontal directions cannot be displaced in the front-to-back direction;

[0128] After the large-area assembly and docking of the present application are completed, the locking connector 2 is in a state where it cannot be displaced and is non-detachable, forming a permanent connection, limit, locking, and fixation effect on the adjacent elastic floor module 1; unless the structures of the elastic floor module 1 and the locking connector 2 are violently damaged, causing the secondary support feet of the elastic floor module 1 to be missing and losing the positioning and limiting effect on the locking connector 2, resulting in damage to the structure of the locking connector 2 and losing the connection, limit, locking, and fixation effect on the adjacent elastic floor module 1; ensuring the long-term stability and tight connection required for sports and fitness activities in the large-area site of the present application.

[0129] The indoor and outdoor universal assembled nail-free sports wooden floor provided by the above embodiment realizes the simple installation and positioning and limiting of the self-locking device 2 through the reasonable setting of the secondary support feet, positioning holes, and limiting grooves; through the positioning, pushing lock, self-locking, limiting, ejector rod limiting lock, special-shaped spring piece, thrust reset access locking and automatic locking settings of the self-locking device 2, the simple assembly of multiple elastic floor modules 1 in the large-area site of the present application and the permanent connection, limit, locking, fixation, and anti-loosening between adjacent floor modules 1 are realized, ensuring the integrity of the large-area paving of the present application and the reliability and firmness for sports and fitness purposes; compared with the existing indoor and outdoor universal nail-free sports wooden floor technology, the present application has no leveling holes, leveling hole plugging plates, and the settings of the elastic eccentric support device other than the elastic rubber pads, with a simpler structure, easier and faster installation, and can be applied to flat sites that do not require leveling at a lower material cost and installation cost; the floor module of the present application is a wood-plastic molded product, which is friendly to the environment and human health, can be recycled and reused, improves the use efficiency of materials, and saves a large amount of solid wood and solid wood products in the existing sports wooden floor technology, reducing the consumption of forest tree resources and being beneficial to the sustainable development of the ecological environment.

[0130] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

When the spring slide head (233) is impacted, squeezed and pushed by external forces from the front and right, a rebound force or elastic thrust force is generated, which drives and forces the push lock arm (23) to swing outward and expand around the axis of the first through hole. The long push rod hole (2311) is located between the special-shaped joint and the clamping head (232) and passes through the left and right side elevations of the outer swing arm (231). An axial hole and an axis that pass through from top to bottom are provided on the side close to the special-shaped joint. The long push rod (234) is provided with a protruding portion protruding from the left side elevation.

When the arc-shaped elevation of the front end is pushed by an external force and the elevation is flush with the left side elevation of the outer swing arm (231), the rear end contacts the inner side elevation of the bottom beam (21), so that the push-lock arm (23) can no longer swing outward around the axis to expand, thereby forming a limit lock on the push-lock arm (23). The small magnet (235) is glued to the upper plane of the long push rod (234) and is magnetically adsorbed on the left side elevation of the outer swing arm (231), so that when the long push rod (234) is in a static state without the action of external force, its front end is stably located above and inside the right end of the clamp (232), and its rear end is stably located at a position that does not touch the thrust device (24). When the outer swing arm swings outward around the axis and expands, the rear end of the long push rod (234) can be inserted into the long fork (211) without hindrance, and the outer swing arm (231) is not restricted from swinging outward and expanding. When the arc-shaped elevation at the front end of the long push rod (234) is pushed and squeezed by external force, the small magnet (235) is separated from the left side elevation of the outer swing arm (231), and the positioning function of the long push rod (234) is lost.
