Description

Technical Field

[0001] The present application relates to the technical field of sports wood floors, and in particular to a nail-free sports wood floor that can be assembled for indoor and outdoor use. Background Art

[0002] Ball games such as basketball, volleyball, and badminton are people's main sports and fitness activities. The physical and mechanical properties of sports wood floors such as shock absorption and rebound 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 force from the ground caused by intense running and jumping when performing basketball, volleyball, badminton and other sports and fitness activities on sports wood floors. At the same time, it helps athletes and sports and fitness enthusiasts to perform and improve their sports and competitive levels normally.

[0003] Application document 2024118972139 discloses a universal nailless sports wooden floor for indoor and outdoor use, which consists of a floor module with leveling holes and a fixing seat, a leveling hole blocking plate and an elastic eccentric support. Elastic eccentricity is used to solve the reasonable force support of venues with large inclination angles and large height differences, and screws, leveling holes, fixing seats and leveling hole blocking plates are used to achieve fast and accurate leveling of the floor module; however, on a flat ground with no inclination angle, no height difference, and no need to level the floor, the leveling function and eccentric support function formed by the combination of the leveling holes, fixing seats, leveling hole blocking plates and elastic eccentric supports in the disclosed technology are wasted and rendered useless.

Axis; the clamp 232 is connected to a spring slide 233 by welding in the middle of the front end facade, and the spring slide 233 is provided with a base and a special-shaped spring sheet, the rear end of the base is in the middle of the front end facade of the clamp 232, and the front end is inclined to the left front at 45°; the special-shaped spring sheet is transitioned with a semicircular and arc-shaped long side, the semicircular end is fixedly connected to the base with a screw, and the arc-shaped long side end is overlapped at the middle position of the semicircular facade on the right side of the clamp 232; the special-shaped spring sheet and the clamp 232 are arranged in a フ shape, the leftmost facade of the semicircular end exceeds the left end of the clamp 232 in the direction perpendicular to the bottom beam 21; the rightmost facade of the arc-shaped long side exceeds the right end of the clamp 232 in the direction perpendicular to the bottom beam 21; the intersection of the semicircular and arc-shaped long sides is flush with the left end of the clamp 232 in the direction perpendicular to the bottom beam 21.

[0017] The outer swing arm 231 is provided with a rectangular long push rod hole 2311 passing through the left and right facades between the special-shaped joint and the clamp head 232. The long push rod hole 2311 is provided with a symmetrical shaft hole passing through the outer swing arm 231 and the long push rod hole 2311 up and down, and a shaft matching the shaft hole. The front end of the left facade of the long push rod 234 is an arc-shaped facade, and the rear end facade is an inclined surface with a lower left side and a higher right side. The long push rod 234 is provided with a protruding protrusion protruding from the left facade. The protruding part is provided with an axial hole that matches the axial hole and the axis of the long push rod hole 2311. After the axial hole of the protruding part is connected to the outer swing arm 231, the long push rod hole 2311 can rotate around the axis within a certain range; under the push of external force, the arc-shaped vertical surface of the front end is flush with the left vertical surface of the connecting arm 221, and the rear end contacts the inner vertical surface 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 for the push-lock arm 23.

[0018] The small magnet 235 is glued to the upper plane of the long push rod 234 and is adsorbed on the left side of the outer swing arm 231 by magnetic force, 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 behind the inner side of the right end of the clamp 232, and does not hinder the secondary supporting foot that comes to dock; the rear end is stably located in a position where it does not touch the thrust device 24, and the rear end of the long push rod 234 is not affected by the inner side of the bottom beam 21 when the outer swing arm swings outward around the axis and expands. The small magnet 235 is inserted into the long fork 211 without any obstruction due to the obstruction of the side elevation, and does not restrict the outer swing arm 231 from swinging outward and expanding; when the arc-shaped elevation at the front end of the long top rod 234 is pushed and squeezed by external force, the small magnet 235 is disengaged from the left elevation of the outer swing arm 231, and loses the restrictive positioning function on the long top rod 234; when the arc-shaped elevation at the front end of the long top rod 234 is flush with the right elevation of the connecting arm 221, the rear end of the long top rod 234 contacts the inner side elevation of the bottom beam 21; The thrust device 24 includes a thick hollow tube 241, a baffle 2411, a thin hollow tube 242, a limiting plate 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 axis hole of the large fork 211, and the front end of the through hole is provided with a baffle 2411, and the baffle 2411 is connected and fixed 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 axis hole of the short fork 2321, and the rear of the through hole is provided with a limiting plate 2421, and the limiting plate 2421 is connected and fixed to the thin hollow tube 242 by welding; the baffle 2411 and the limiting plate 2421 are used to limit the front and rear ends of the thrust spring 243 to enable it to exert thrust.

[0019] The thrust spring 243 is inserted into the thick hollow tube 241 from the front end of the thick hollow tube 241, and the end thereof abuts against the blocking 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 axial hole and the axis of the long fork 211, and the through hole at the front end of the thin hollow tube 242 is connected to the bottom beam 21 through the axis and the axis hole of the short fork 2321, so that the thrust device 24 generates a thrust to the external swing arm 231.

[0020] 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.

[0021] When the spring slide 233 is impacted, squeezed and pushed by the external forces from the front and right sides, the rebound force or elastic thrust generated by its arc-shaped long side is greater than the thrust applied to the push-lock arm 23 by the thrust device 24, thus driving and forcing the push-lock arm 23 to swing outward around the axis of the first through hole 212 and expand to unload the force; when the external force of the spring slide 233 disappears and the reset obstacle of the push-lock arm 23 disappears, the thrust of the thrust device 24 pushes the push-lock arm 23 to quickly return to its original position; because the thrust of the thrust spring 243 is greater than the magnetic attraction of the small magnet 235 on the outer swing arm 231, the arc-shaped vertical surface at the front end of the long push rod 234 is pushed and squeezed by the external force, so that when the small magnet 235 is disengaged from the left vertical surface of the outer swing arm 231, the reset action of the push-lock arm 23 and the static state after reset are not affected; The small magnet 235 is disengaged from the left side facade of the outer swing arm 231, losing its positioning effect on the long push rod 234; when the arc-shaped facade at the front end of the long push rod 234 is flush with the right side facade of the connecting arm 221 under the action of external force, the rear end also contacts the inner side facade of the bottom beam 21, forming a limit positioning for the push-lock arm 23, so that the push-lock arm 23 can no longer expand or swing outward due to any external force.

[0022] Multiple elastic floor modules 1 are assembled horizontally in the front and back and left and right directions at the edge of the panel 10: the tenon at the front edge of the first elastic floor module 1 and below the panel 10 is inserted into the tenon groove at the rear edge of the second elastic floor module 1 and below the panel 10; the tenon groove at the left edge of the third elastic floor module 1 and below the panel 10 is simultaneously sleeved with the tenon at the right edge of the first elastic floor module 1 and the second elastic floor module 1; The front support foot 13 of the first elastic floor module 1 and the rear support foot 17 of the second elastic floor module 1 form a docking support foot of the same size as the main support foot 11, and the front limit groove 131 and the rear limit groove 171 also form a limit arm accommodating cavity for accommodating the limit arm 222; 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 right support foot 15; The left front support foot 12 of the first elastic floor module 1 and the left rear support foot 18 of the second elastic floor module 1 form a docking support foot of the same size as the left support foot 19; The left support foot 19 of the first elastic floor module 1 and the right support foot 15 of the third elastic floor module 1 form a docking support foot of 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 accommodating chamber for accommodating the limit arm 222; The left supporting foot 19 of the third elastic floor module 1, the right front supporting foot 14 of the first elastic floor module 1, and the right rear supporting foot 16 of the second elastic floor module 1 form a docking supporting foot of the same size as the main supporting foot 11; the left limiting groove 191 and the right front limiting groove 141 also form a limiting arm accommodating cavity for accommodating the limiting arm 222;.

[0023] Multiple floor modules 1 are assembled horizontally in the left and right and front and back directions at the edge of the panel 10: the mortise and tenon at the right edge of the first elastic floor module 1 and below the panel 10 are sleeved with the mortise and tenon at the left edge of the second elastic floor module 1 and below the panel 10; the mortise and tenon at the left edge and rear edge of the third elastic floor module 1 and below the panel 10 are sleeved with the mortise and tenon at 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; The right support foot 15 of the first elastic floor module 1 and 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 limit groove 191 and the right limit groove 151 also form a limit arm accommodating cavity for accommodating the limit arm 222; The left supporting foot 19 of the first elastic floor module 1, the left front supporting foot 12 of the second elastic floor module 1, and the left rear supporting foot 18 of the third elastic floor module 1 constitute a docking supporting foot with the same size as the main supporting foot 11, and the left limiting groove 191 and the left front limiting groove 121 also constitute a limiting arm accommodating cavity for accommodating the limiting arm 222;.

[0024] Installation and application of the locking device 2 on the elastic floor module 1; install the locking device 2 on the front supporting foot 13 and the right supporting foot 15, and do not install the locking device 2 on the other supporting feet; stand up the elastic floor module 1, place the self-locking arm 22 of the locking device 2 on one side of the limiting 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 outward so that the front supporting foot 13 is between the push-locking arm 23 and the self-locking arm 22, and at the same time, insert the positioning pin 214 into the front positioning hole 132, and the bottom beam 21 fits the rear side of the front supporting foot 13, then release the push-locking arm 23, press the self-locking arm 22 to make the limiting arm 222 completely fit into the limiting groove 131; When the limiting arm 222 is fully engaged in the limiting groove 131, the front arc-shaped surface of the top rod 223 is flush with the left side surface of the connecting arm 221 and is in close contact with the right side surface of the supporting foot 13. The rear end of the top rod 223 also contacts the inner side surface of the bottom beam 21, thereby locking the self-locking arm 22 so that it can no longer swing or expand outwards around the axis due to any external force, thereby clamping the front supporting foot 13. Furthermore, the rear end of the top rod 223 abuts against the bottom beam 21, and the bottom beam 21 is also locked in position, thereby positioning and fixing the lock link 2 on the front support leg 13; unless the bottom beam 21 slides to the right along the rear end vertical surface of the front support leg 13, the self-locking arm 22 will be displaced, loosened and lose the self-locking function, causing the lock link 2 to fall off the front support leg 13; Furthermore, the positioning pin 214 in the front positioning hole 132 forms a restriction on the bottom beam 21, so that the bottom beam 21 that is close to the rear end elevation of the front support leg 13 cannot rotate backward around the axis under the restriction of the self-locking arm 22, and cannot be displaced in any direction on the rear end elevation of the front support leg 13; Furthermore, under the locking and positioning joint action of the self-locking arm 22 and the positioning pin 214, the locking link 2 firmly locks the front supporting leg 13. At this time, unless the front supporting leg 13 or the locking link 2 is violently damaged, the locking link 2 will not change the position of the bottom beam 21 due to the impact and extrusion of the spring slide 233 at the front end of the push-locking arm 23 by other supporting legs during assembly and docking, resulting in the oblique and backward force, which drives the self-locking arm 22 to lose its self-locking function, thereby causing the locking link 2 to loosen, fall off, and fail. Furthermore, at this time, the arc-shaped vertical surface on the left side of the front end of the long push rod 234 is not touched or displaced by external force, so under the magnetic limit of the small magnet 235, the long push rod 234 does not restrict the outward swing expansion of the push-lock arm 23.

[0025] 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.

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. The right rear support foot 16 of the second elastic floor module 1 is also connected to the right front support foot 14 of the first elastic floor module 1. The lock connector 2 is taken out to place the self-locking arm 22 on the side of the right front limit groove 141, and the positioning pin 214 is on the side of the right rear positioning hole 161. The lock connector 2 is placed on the inner rear of the right rear and right front docking support feet through the space between the arch support and the ground, and the push lock arm 23 and the self-locking arm 22 are pulled outward to expand the right rear and right front support feet.

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are 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 to facilitate a full understanding of 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 violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below; the specific implementation of the present application is described in detail below in combination with the drawings and specific embodiments. Example

[0037] like Figure 1 to Figure 15 As shown, an embodiment of the present application provides a general-purpose indoor and outdoor assembled nailless sports wooden floor, including an elastic floor module 1 and a locking connector 2; a plurality of supporting feet are provided at the lower end of the elastic floor module 1, and the locking connector 2 realizes permanent connection, limiting, locking, fixing of adjacent elastic floor modules 1 and large-area assembly and paving of the elastic floor modules 1 by permanently connecting, limiting, locking and fixing adjacent supporting feet, thereby forming a large plane required for sports and fitness exercises.

[0038] like Figure 2~Figure 5 As shown, the elastic floor module 1 is composed of a floor module and an elastic rubber pad; the floor module is a polymer composite wood-plastic product, which is environmentally friendly and non-toxic, and is friendly to human health and the ecological environment. As a tough and elastic material, it has the advantages of strong plasticity, pressure resistance, impact resistance, high and low temperature resistance, moisture resistance, and long service life. As a product form of polymer composite wood-plastic, wood-plastic flooring is widely used. At the same time, it can also prevent insects and termites, so wood-plastic flooring can be used in complex environments where traditional solid wood products cannot be used.

[0039] Compared with extrusion production, which can only produce products with simple structural shapes like narrow strips, the advantages of using the plasticity of plastic materials for molding production are: good repeatability, simple operation, and product quality is not affected by the operator and external conditions; the product molding cycle is short, complex structures are molded in one time, the size of the pressed products is precise, the surface of the pressed products is smooth and smooth, and the surface treatment is more convenient; high-intensity pressure makes the mass density of the pressed products larger and stronger, the product stability is better, the cold and hot expansion rate is low, the bending and compression resistance is stronger, the load-bearing capacity is better, and the overall cost of materials is lower.

[0040] like Figure 2~Figure 5 As shown, the elastic floor module 1 includes a floor module and an elastic rubber pad; a panel 10 is provided at the upper end of the floor module, and the upper surface of the panel 10 is the use surface for sports and fitness activities in this application; a plurality of main supporting feet 11 and a plurality of secondary supporting feet are provided at the lower end of the floor module and the back of the panel; the plurality of secondary supporting feet include a left front supporting foot 12, a front supporting foot 13, a right front supporting foot 14, a right supporting foot 15, a right rear supporting foot 16, a rear supporting foot 17, a left rear supporting foot 18, and a left supporting foot 19; The bottom surface of the main support foot 11 is provided with four square protrusions, 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, and 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; Elastic rubber pads are provided under the main supporting feet and each secondary supporting foot, and the upper plane of each elastic rubber pad is provided with a square recess corresponding to the square protrusion; each supporting foot is connected to its own elastic rubber pad by gluing, and the square protrusion is plugged into the square recess; the purpose of providing the square protrusion and the square recess is to increase the contact area between the supporting foot and the elastic rubber pad, thereby increasing the firmness of the gluing, and the connection with the square protrusion and the square recess can ensure that when the elastic floor module 1 is pushed for assembly, the elastic rubber pad is prevented from rotating or other position changes on the bottom surface of the supporting foot due to the friction resistance of the ground, thereby affecting the docking of the secondary supporting foot.

[0041] like Figure 2~Figure 5 , Figure 12~Figure 15 As shown, the front supporting foot 13 is provided with a front limiting groove 131 and a front positioning hole 132, the rear supporting foot 17 is provided with a rear limiting groove 171, the left front supporting foot 12 is provided with a left front limiting groove 121, the right front supporting foot 14 is provided with a right front limiting groove 141, and the right rear supporting foot 16 is provided with a right rear positioning hole 161; a plurality of elastic floor modules 1 are butted together in the front and rear horizontal directions, the front supporting foot 13 and the rear supporting foot 17 form a butt-jointed supporting foot of the same size as the main supporting foot 11, the front limiting groove 131 and the rear limiting groove 171 form a limiting arm accommodating cavity for accommodating the limiting arm 222; the left front supporting foot 12 and the left rear supporting foot 18 form a butt-jointed supporting foot of the same size as the left supporting foot 19; the right front supporting foot 14 and the right rear supporting foot 16 form a butt-jointed supporting foot of the same size as the right supporting foot 15; The right support foot 15 is provided with a right limiting groove 151 and a right positioning hole 152, and the left support foot 19 is provided with a left limiting groove 191; the plurality of elastic floor modules 1 are butted together in the left and right horizontal directions, and the right support foot 15 and the left support foot 19 form a butted support foot of the same size as the main support foot 11, and the right limiting groove 151 and the left limiting groove 191 form a limiting arm accommodating cavity for accommodating the limiting arm 222; The right supporting foot 15, the left front supporting foot 12 and the left rear supporting foot 18 form a docking supporting foot of the same size as the main supporting foot 11, and the right limiting groove 151 and the left front limiting groove 121 form a limiting arm accommodating chamber for accommodating the limiting arm 222; the left supporting foot 19, the right front supporting foot 14 and the right rear supporting foot 16 form a docking supporting foot of the same size as the main supporting foot 11, and the left limiting groove 191 and the right front limiting groove 141 accommodate the limiting arm accommodating chamber for accommodating the limiting arm 222; The rear limit slot 171 is different from other limit slots in that it runs through the rear end elevation of the entire rear support foot 17 and is twice as long as other limit slots; the purpose is to eliminate the obstruction of the limit arm 222 to the right push when multiple elastic floor modules 1 are assembled and docked and need to be pushed to the right.

[0042] By setting the above-mentioned secondary support feet, limiting grooves and positioning holes, it is ensured that after the multiple elastic floor modules 1 are assembled in the front-to-back and left-to-right horizontal directions, the locking connector 2 with a single size specification is installed on each secondary support foot and the docking support foot through the limiting grooves and positioning holes. When the multiple elastic floor modules 1 are assembled, the secondary support feet below the edges of the multiple elastic floor modules 1 are connected, limited, locked and fixed, thereby realizing the connection, limitation, locking and fixation of the multiple elastic floor modules 1 as individual individuals by the locking connector 2, so that the present application can obtain the large-area floor venue required for sports.

[0043] like Figure 2~Figure 5As shown, matching tongues and grooves are provided below the edge of the panel 10, and the tongues and grooves are provided below the edge of the panel 10 without destroying the strength of the edge of the panel 10; after multiple elastic floor modules 1 are spliced ​​in the horizontal direction of front, back, left, and right, the tongues and grooves are inserted and inserted, so that adjacent elastic floor modules 1 can restrict and support each other, thereby enhancing the integrity of multiple elastic floor modules 1 after large-area paving; the difference between the upper and lower thicknesses of the tongues and the upper and lower widths of the grooves is ≤0.2mm. Under the influence of the external environment of high temperature, low temperature, air humidity, and seasonal climate changes, the tongues and grooves that are inserted and inserted have a margin for contraction and expansion, and avoid the tongues and grooves that are inserted and inserted in the front and back directions when multiple elastic floor modules 1 are spliced. The elastic floor module 1 cannot be pushed to the right or is difficult to push to the right due to excessive bite, thereby ensuring that multiple elastic floor modules 1 are smoothly and smoothly assembled.

[0044] Furthermore, when athletes walk, run, jump, and step on the upper surfaces of the panels 10 of two adjacent elastic floor modules 1 that have been assembled in the front and back and left and right directions, and the soles of their feet generate downward gravity and impact force on the edges of the adjacent panels 10, the tenon and mortise joint supports limit and restrict each other, and jointly disperse the gravity and impact force transmitted to the edges of the panels 10, thereby preventing the edges on either side from bearing the gravity and impact force alone and generating different instantaneous deformations and vibration frequencies, thereby ensuring that the edges of the adjacent panels 10 of the adjacent elastic floor modules 1 assembled and connected in the front and back and left and right directions, and the upper surfaces of the floor on both sides of the edges of the adjacent panels 10 are always in the same state in terms of level, instantaneous deformation, and vibration frequency, thereby preventing the edges of the adjacent panels 10 of the adjacent elastic floor modules 1 and the upper surfaces of the floor on both sides of the edges of the adjacent panels 10 from having different horizontal heights during intense competitive sports, thereby preventing the soles of athletes from colliding and endangering personal safety, and different instantaneous deformations and vibration frequencies from affecting technical performance.

[0045] like Figure 4 , Figure 5 As shown, on the back of the panel 10, arch supports are provided between each supporting foot, and reinforced supports arranged in a tic-tac-toe pattern and intersecting and connecting with each arch support vertically; when athletes walk, run, jump, and step on the upper surface of the panel 10 of the elastic floor module 1, and the soles of their feet generate downward gravity and impact force between the parallel arch supports, in addition to the panel 10 directly dispersing it to the surroundings, the reinforced supports also directly transmit it to each arch support intersecting and connecting with it vertically, so as to avoid collapse and deformation between the parallel arch supports caused by long-term gravity impact; and quickly feed back 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 arch supports; avoid different shock absorption effects and rebound forces at the position with arch support and the position without arch support at the bottom of the upper surface of the panel 10 of the floor module 1, so as to promote the uniform display of the elasticity and shock absorption physical and mechanical properties of the floor module 1; 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] like Figure 6 , Figure 7 As shown, the limiting arm 222 of the self-locking arm 22 has two upper and lower outer corners at the front end and an outer corner at the left end thereof set as bevels, which is beneficial to reduce the corner collision when the limiting grooves are butt-jointed with the limiting arm 222; Furthermore, when athletes walk, run, jump or step on the upper surface of the panels 10 of two adjacent elastic floor modules 1 that have been assembled in the front-to-back and left-to-right directions, and the soles of their feet generate downward gravity and impact force on the edges of the adjacent panels 10, the limiting arm 222 in the limiting arm accommodating cavity, due to the limiting restriction of the limiting groove, forms a common limiting restriction on the adjacent elastic floor modules 1 with the mortise and tenon grooves that are mutually fitted and plugged on the lower edge of the panel 10, thereby further enhancing the long-term stability of the present application after large-area paving.

[0050] The top rod 223 of the self-locking arm 22 and the long top rod 234 of the push-lock arm 2 have arc-shaped vertical surfaces facing the inside of the front end. When the lock connector 2 is installed, the arc-shaped vertical surface contacts and is squeezed with the vertical surface of the support foot, and can slide and displace on the vertical surface of the support foot with very small friction resistance, so that the top rod can smoothly rotate around the axis in the top rod hole, driving the rear end to contact the inner vertical surface of the bottom beam 21, and quickly realizing the limit locking of the self-locking arm 22 and the push-lock arm 23 by the top rod; like Figure 8~Figure 15 As shown, the small magnet 235 arranged on the long push rod 234 ensures that when the long push rod 234 is in a static state without the action of external force, its front end is stably located on the left side of the right end of the clamping head 232 in a direction perpendicular to the bottom beam 21, and does not hinder the secondary supporting foot that comes to dock; the rear end is stably located in a position where it does not touch the thrust device 24, ensuring that the rear end of the long push rod 234 is not hindered by the inner side surface of the bottom beam 21 when the outer swing arm 231 swings outward around the axis and expands. The push rod 223 can be inserted into the long fork opening 211 without hindrance because the self-locking arm 22 is manually installed without setting a position. Therefore, the push rod 223 can rotate around the axis without hindrance before the lock link 2 is installed on the secondary support leg, and does not limit the self-locking arm 22 from expanding outward around the axis. The setting of the push rod 223 enables the lock link 2 to form a self-locking effect on the lock link 2 through the self-locking arm 22 clamping the secondary support leg after the lock link 2 is installed on the secondary support leg, and then form a stable self-locking position together with the positioning pin 214. like Figure 8~Figure 11 As shown, the small magnet 235 positions the long push rod 234 and the long fork 221, so that when the lock connector 2 accepts the docking of the secondary support leg, the axial outward swing and expansion of the push-lock arm 23 are not restricted by the long push rod 234, and after accepting the docking of the secondary support leg, under the thrust of the thrust device 24, the lock connector 2 completes the access locking and automatic locking.

[0051] The rear end of the push rod (223) is a sloped surface with a higher left side and a lower right side, and the rear end of the long push rod (234) is a sloped surface with a lower left side and a higher right side, so as to ensure that the rear ends of the two push rods can smoothly move to a position that contacts the bottom beam 21.

[0052] like Figure 8~Figure 15 As shown, the special-shaped spring piece of the spring slide 233 is arranged in a フ shape with the clamping head 232, with a semicircular and arc-shaped long side transition, and the end of the arc-shaped long side overlaps the middle position of the semicircular vertical surface on the right side of the clamping head 232; the spring piece, as an elastic material, has the performance of bearing pressure and rapid rebound. The special-shaped spring piece transitions to the long side of the semicircular vertical surface on the right side of the clamping head 232, and is set to be an arc transition rather than a straight line transition, because the arc can better transmit the force to the outward swing arm 231 quickly and rebound instantly to release elastic potential energy after being squeezed and collided by the external force from the secondary support foot, forcing the outward swing arm 231 to be pressed and collided. The arm 231 quickly swings and expands outward around the axis, opens the docking channel of the secondary support leg, and enables the secondary support leg to dock smoothly; the end of the arc-shaped long side overlaps the middle position of the semicircular vertical surface on the right side of the clamp 232, and the overlap method is adopted instead of the fixed method. Because the arc-shaped long side of the special-shaped spring sheet is squeezed and collided by the external force from the secondary support leg, it is instantly deformed from an arc to a straight line, and the length increases instantly. The overlap method does not hinder the end of the arc-shaped long side from instantly stretching and extending on the semicircular vertical surface of the clamp 232, and it quickly retracts when rebounding to restore the arc, and does not hinder the docking of the secondary support leg; Furthermore, multiple elastic floor modules 1 are assembled in the horizontal direction of front, back, left and right. When installing the second block of the second road, first push back to make the front and back dock, and then push left to make the left and right dock; after the front and back dock, the front end elevation and corner of the left secondary supporting foot that is about to move to the left for docking are on the same straight line in the left-right direction with the right side elevation of the outer swing arm 231 of the locking connector 2 on the right secondary supporting foot; the leftmost elevation of the semicircular end of the special-shaped spring sheet exceeds the left end of the clamp 232 in the direction perpendicular to the bottom beam 21; the intersection of the semicircular and arc-shaped long sides is flush with the left end of the clamp 232 in the direction perpendicular to the bottom beam 21; these position settings are far beyond the right side elevation of the outer swing arm 231, expanding the range of action of the arc-shaped long side and thereby increasing the access range of the left secondary supporting foot, ensuring that when there is a limited position deviation between the left and right supporting feet during docking, they can still be docked smoothly; 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.

[0053] 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.

[0054] 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.

[0055] like Figure 1 , Figure 6~Figure 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; After the large-scale assembly and docking of the present application is completed, the locking connector 2 is in a state that cannot be displaced and cannot be disassembled, forming a permanent connection, limitation, locking and fixing effect on the adjacent elastic floor modules 1; unless the structure of the elastic floor module 1 and the locking connector 2 is violently destroyed, the secondary supporting foot of the elastic floor module 1 is missing, and the positioning and limiting effect of the locking connector 2 is lost, the structure of the locking connector 2 is damaged and the connection, limitation, locking and fixing effect on the adjacent elastic floor modules 1 is lost; ensure that the large-area venue of the present application is used for the long-term stability and tight connection required for sports, competitive fitness.

[0056] The general indoor and outdoor assembled nailless sports wooden floor provided in the above embodiment realizes simple installation and positioning and limiting of the self-locking device 2 through the reasonable arrangement of the secondary supporting feet, positioning holes and limiting grooves; through the positioning, push locking, self-locking, limiting, top rod limiting locking, special-shaped spring sheet, thrust reset access locking automatic locking and locking settings of the self-locking device 2, the simple assembly of multiple elastic floor modules 1 in a large area of ​​the present application and the permanent connection, limiting, locking, fixing 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 competition and fitness purposes; Compared with the existing general indoor and outdoor nailless sports wood floor technology, the present application has no leveling holes, leveling hole blocking plates, and elastic eccentric supports other than elastic rubber pads. The structure is simpler, and the installation is easier and faster. It can be used on a flat site that does not require leveling with lower material and installation costs.
