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 for indoor and outdoor use. Background Art

[0002] Basketball, volleyball, badminton and other ball games are the main sports and fitness activities for people, and sports floor materials are the best elastic carriers for sports venues. The physical and mechanical properties of sports wood flooring, such as shock absorption and rebound, can allow 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 due to intense running and jumping when playing basketball, volleyball, badminton and other sports and fitness activities on sports wood flooring, while helping athletes to perform and improve their sports and competitive levels.

[0003] The existing sports wood floor technology includes: one is a levelable sports wood floor; for example, CN107013011A discloses a traditional solid wood sports wood floor with a double-layer keel structure, US201615146607A discloses a traditional solid wood sports wood floor with a multi-board stacked structure, CN111910487A discloses an outdoor sports wood floor with a double-layer keel structure and a construction method, CN217924615U discloses a double-layer oblique cross-keel structure that can be used for outdoor sports wood flooring, and CN212897386U discloses an outdoor sports wood floor with a double-layer keel structure; the existing levelable sports wood floor, the leveling method is to cut and make different thicknesses of boards, wood squares, plastics and other materials into different thicknesses Small pieces of leveling materials are manually filled between the floor and the base layer to eliminate the height difference of the base layer and serve as the supporting structure between the floor and the base layer to serve as the supporting point of the sports wooden floor. In some base layers with large height difference and large inclination angle due to drainage needs, such as roof base layers, outdoor concrete base layers, outdoor marble base layers, etc., a large amount of leveling materials need to be filled between the floor and the base layer. The greater the height difference of the base layer and the greater the inclination angle, the more materials need to be filled and the more labor is required. Moreover, the lower plane of the support point cannot fit the base layer with an inclination angle, resulting in a situation where one side of the support point is grounded and the other side is suspended in the air with uneven force, which affects the stability and service life of the floor.

[0004] The second is a detachable sports wooden floor that cannot be leveled, such as CN217128841U which discloses a detachable traditional solid wood sports wooden floor with a single-layer keel structure, US19980081799A which discloses a detachable traditional solid wood sports wooden floor, and JPH05113025A which discloses a double-layer plate structure of traditional solid wood sports wooden floor. None of them are provided with leveling pads and have no leveling function. They have high requirements on the flatness of the base layer. The use of this type of sports wooden floor will result in a higher investment in the flatness of the base layer. Because it cannot be leveled, it is not suitable for base layers with large height differences and large inclination angles.

[0005] The structure of the existing sports wood floor technology is that each component is stacked layer by layer. Different types of nails must be used between the stacked components for complex connection and fixing operations. In addition, the amount of nails used and the number of nail insertion points are huge. If a nail is not nailed deep enough and fails to produce the desired connection and fixing effect, or if a nail is nailed into the wrong position and fails to produce the desired connection and fixing effect, or if a nail at a certain position has quality problems and breaks or bends and loses its connection and fixing effect, it will cause the component at that position to loosen, becoming a quality hazard of the sports wood floor. After the sports wood floor venue is put into use, due to the connection and fixing reasons of the above-mentioned nails, the elastic The failure, loosening and displacement of the connection between rubber pads, leveling pads and keels causes the keel above that position to lose support and become suspended in the air, the upper and lower keels to loosen, and the connection and fixation between the keel and the bearing plate / multi-layer plate / subfloor fails, and the connection and fixation between the surface plate and the lower component fails, causing structural damage and abnormal noise when stepped on. The loss of stable support directly leads to hollowing of the floor, further endangering the personal safety of athletes and sports and fitness participants. When the above problems occur and repairs are carried out, at least the original surface floor must be destroyed, and the bearing plate / multi-layer plate / subfloor must be destroyed if necessary, and replaced with new materials, resulting in resource loss and labor cost loss.

[0006] To sum up, the existing sports wood floor technology has problems such as structural stacking, large material consumption and high material costs, large leveling workload and inability to quickly and accurately level, inability to level and no leveling function, poor applicability to indoor and outdoor venues with large height differences and large inclination angles, large consumption of metal nails, cumbersome installation procedures and high installation costs. The existing sports wood floor technology uses a large number of solid wood surface layers, solid wood keels and other solid wood products, which consume forest resources and do not meet the requirements of ecological environmental protection and sustainable development.

Under the action of gravity, the two card groove support protrusions 1111 on the back side of the leveling hole sealing plate 111 are pressed between the card plates 261, and the fastening card grooves 1112 are held and clamped from the outside to the inside by the card heads on both sides of the card plate 261, so as to realize the connection and fixation of the elastic eccentric support 2 to the leveling hole sealing plate 111.

[0060] The tray mounting hole 242 , the buckle cover mounting hole 254 , the gasket mounting hole 262 , together with the mounting holes of the main fixing seat or the docking fixing seat in the tray 24 and the buckle cover 25 , form a through hole, which is convenient for the long barrel nut 232 to penetrate.

[0061] The inverted T-shaped support screw 22 and the long-barrel nut 232 pass through the through holes of the tray 24, the main fixing seat 121 or the docking fixing seat, the buckle cover 25, and the gasket clamp 26, so as to abut the upper plane of the load-bearing chassis 231 against the lower plane of the tray 24; the long-barrel nut 232 is connected to the hexagonal nut 27 through the right-handed thread on the outer wall on the plane of the bottom plate of the gasket clamp 26, and the cube quadrilateral head 233 is completely exposed above the hexagonal nut 27, and the rectangular quadrilateral head 2223 is completely exposed above the cube quadrilateral head 233.

[0062] After the long barrel nut 232 is connected to the hexagonal nut 27, the hexagonal nut 27 is not locked, so that the inverted T-shaped adjusting nut 23 is in a rotatable state; first, use a wrench to clamp the rectangular four-sided head 2223 of the screw rod 222, and adjust the direction of the direction indicating arrow 2224. If the base layer 3 is an indoor or outdoor concrete base layer, an outdoor marble slab base layer, or an outdoor roof base layer with a large height difference, adjust the arrow 2224 to point to the direction of the high ground. At this time, due to the position limit of the eccentric shaft seat 213 of the elastic eccentric support 2, one side of the half of the long five-part division of the elastic eccentric shaft seat 21 is on the side of the high ground of the base layer 3; if the height difference of the base layer 3 is within a range of 15 meters ≤5cm, all the direction indicating arrows 2224 point to the same direction; use another wrench to clamp the cube four-sided head 233 of the inverted T-shaped adjusting nut 23, and rotate the inverted T-shaped adjusting nut 2 3, while keeping the screw rod 222 in a stationary state, the floor module 1 is driven to rise or fall by the clockwise or counterclockwise rotation of the inverted T-shaped adjusting nut 23 on the screw rod 222, and the floor module 1 is leveled; after the upper surface of the panel 10 is adjusted to the required horizontal height, the wrench on the rectangular quadrilateral head 2223 is removed, and the hexagonal nut 27 is clamped with the wrench, and the inverted T-shaped adjusting nut 23 is kept in a stationary state while the hexagonal nut 27 is rotated counterclockwise, and the hexagonal nut 27 is locked to realize the connection, locking and fixation of the elastic eccentric support 2 to the main fixing seat 121 or the docking fixing seat, and then realize the connection, locking, fixation and stable support of the elastic eccentric support 2 to the floor module 1 below the main leveling hole 11, and realize the connection, locking, fixation and stable support of the adjacent floor module 1 below the docking leveling hole.

[0063] The inverted T-shaped adjusting nut 23 is connected to the left-handed coarse thread of the inverted T-shaped supporting screw 22 through the left-handed coarse thread of the inner hole of the long barrel nut 232, and is connected to the hexagonal nut 27 through the right-handed thread set on the outer wall. The rotation directions and locking forces of the two threads are opposite and restrain each other. After the hexagonal nut 27 is locked with the inverted T-shaped adjusting nut 23, the inverted T-shaped adjusting nut 23 can only be loosened in the clockwise direction by rotating the hexagonal nut 27 in the clockwise direction. The weight of the floor module 1 itself and the gravity and impact force generated by sports make the inverted T-shaped adjusting nut 23 always in a load-bearing state, and can only generate a downward unloading force on the left-handed thread of the inverted T-shaped supporting screw 22 by counterclockwise rotation. However, the right-handed thread connection between the outer wall thread and the hexagonal nut 27 is locked by counterclockwise rotation. Therefore, the counterclockwise unloading force of the inverted T-shaped adjusting nut 23 is offset and restricted by the hexagonal nut 27, and the position change on the inverted T-shaped supporting screw 22 cannot occur.

[0064] After the elastic eccentric support 2 is leveled and tightened, the long barrel nut 232 and the screw 222 that are higher than the upper plane of the hexagonal nut 27 are cut off with a handheld lithium-electric cold-cutting saw, and then the flat head of the flat-headed triangular locking block 2222 is aligned and inserted into the locking groove 2221, with the bottom surface fitting the bottom surface of the vertical surface of the locking groove 2221, and the back of the beveled tooth tip facing the inner hole thread of the adjusting nut 232, and the triangular plane of the flat-headed triangular locking block 2222 is hit with a hammer to make it completely wedge into the locking groove 222 1. The oblique tooth tip back of the flat-head triangular locking block 2222 is cut off and embedded in the inner thread of the long barrel nut 232, so that the inverted T-type adjusting nut 23 and the inverted T-type supporting screw 22 are completely stuck, so that the inverted T-type supporting screw 22 cannot produce any position change on the screw 222 through self-rotation under the action of gravity and impact force, and cannot produce any position change on the base ground with a large inclination angle through self-rotation of the elastic eccentric shaft seat 21 to affect the eccentric support effect.

[0065] The length of the flat-headed triangular locking block 2222 is the same as the height of the hexagonal nut 27. After it is completely wedged into the locking groove 2221, the portion where the long barrel nut 232 and the hexagonal nut 27 are connected is pushed outward, so that the long barrel nut 232 changes from a round shape to an irregular shape, and the hexagonal nut 27 is completely stuck, so that the hexagonal nut 27 cannot rotate at all under the gravity and impact force generated by the dead weight of the floor module 1 and physical fitness exercises, thereby completing and realizing the permanent positioning, locking, and anti-loosening between the threads of the elastic eccentric supporter 2, so that the upper surfaces of the panels 10 of the multiple floor modules 1 after installation are kept in the same horizontal state for a long time.

[0066] S4. Further, the two card slot support protrusions 1111 on the back of the leveling hole plugging plate 111 are placed in the direction of the card plate 261 of the gasket card plate 26, and are placed in each main leveling hole 11 or the docking leveling hole. The outer bevels of the bottom surfaces of the two card slot support protrusions 1111 are placed on the upper bevels of the clamping heads respectively. The leveling hole plugging plate 111 is stepped on with the foot to apply downward gravity, so that the two card slot support protrusions 1111 are squeezed outward, and the two clamping heads expand outward and slide in to tighten. The card slot 1112 forms a firm lock of the gasket clamping plate 26 on the leveling hole blocking plate 111 to prevent the leveling hole blocking plate 111 from loosening under external force; at the same time, the lower plane of the protrusion 1111 supported by the two card slots is tightly attached to the upper plane of the bottom plate of the gasket clamping plate 26, so that the elastic eccentric support 2 and the support platform 101, and the docking combined support platform composed of the left support platform 1011 and the right support platform 1012, together form a double support for the leveling hole blocking plate 111.

[0067] The elastic eccentric support 2 is manufactured in the factory. After the production is completed, the inverted T-shaped support screw 22 and the elastic eccentric shaft seat 21 are assembled, so that the direction indicator arrow 2224 points to the short side of the plane on the elastic rubber pad limit seat 212 close to the eccentric shaft seat 213; the shaft 214 and the eccentric shaft seat 213 are spot welded on the outer surface of one side of the eccentric shaft seat 213 to prevent the shaft 214 from loosening and causing the elastic eccentric shaft seat 21 to lose the connection support to the inverted T-shaped support screw 22; the gasket clamp 26 is fixed on both sides of the clamp 261 in accordance with the buckle cover 2 5, the gasket mounting holes 262 are aligned with the buckle cover mounting holes 254, and the gasket clamping plate 26 and the buckle cover 25 are spot-welded and fixed on the short sides of the buckle cover 25, so that the buckle cover 25 and the gasket clamping plate 26 become one body, and the gasket clamping plate 26 is positioned to prevent the hexagonal nut 27 from rotating and locking on the bottom plate plane of the gasket clamping plate 26, which drives the gasket clamping plate 26 to rotate, thereby affecting the smooth connection between the leveling hole blocking plate 111 and the gasket clamping plate 26 when installing.

[0068] The factory state of the elastic eccentric support 2 is: the inverted T-shaped adjusting nut 23 is rotated and assembled onto the inverted T-shaped support screw 22, so that it is at the bottom of the inverted T-shaped support screw 22; the buckle cover 25 and the gasket clamp 26 are spot welded and fixed; the assembled elastic eccentric shaft seat 21, inverted T-shaped support screw 22, and inverted T-shaped adjusting nut 23 are separately packaged as the factory combination of the elastic eccentric support 2; other components are not assembled and packaged separately.

[0073] Supplies: corresponding number of floor modules 1 and elastic eccentric supports 2;

[0074] S3: Before leveling, at the site with large height difference of base 3, first use a wrench to adjust the direction indicator arrow 2224 to point to the direction of high terrain; if the height difference of the base 3 is within 15 meters or less than 5cm, all the direction indicator arrows 2224 point to the same direction, and then assemble, level and fix the floor modules 1 piece by piece from back to front, complete the installation of the first route, assemble the second route on the left side of the first route, and after completing the installation of the second route, assemble the third route on the left side of the second route, and gradually complete the assembly, leveling and fixing of the floor modules 1 of the entire site by assembling and docking on the left side of each route;

[0075] S5: Use a handheld lithium-electric cold-cut saw to cut off the long-barrel nut 232 and the screw 222 that are higher than the upper plane of the hexagonal nut 27 on the upper plane of the hexagonal nut 27; align the oblique tooth tip back of the flat-headed triangular locking block 2222 with the long-barrel nut 232, insert the flat head into the locking groove 2221, and use a claw hammer to completely smash the flat-headed triangular locking block 2222 into the locking groove 2221;

[0076] S6: Use self-spraying anti-rust paint to spray the cutouts of the long-barrel nut 232 and the screw rod 222; put the leveling hole sealing plate 111 into the leveling hole, and step down on the leveling hole sealing plate 111 with your foot to connect and fix it with the gasket clamping plate 26.

[0077] In S1, the standard height of the present application is that after the elastic eccentric support 2 is installed on the floor module 1, the inverted T-shaped adjusting nut 23 is lowered to the lowest position on the inverted T-shaped support screw 22, and the bottom surface of the elastic rubber pad 211 is parallel to the upper surface of the panel 10, at this time, the height from the bottom surface of the elastic rubber pad 211 to the upper surface of the panel 10 is the self-elevation of the present application; the height of the highest point of the base layer 3 plus the standard height of the present application is used as the unified upper surface elevation of the present application; the height of the lowest point of the base layer 3 plus the unified upper surface elevation of the present application, the value obtained plus 5cm is the length of the inverted T-shaped support screw 22; this length ensures that during and after the leveling process of each elastic eccentric support 2, no matter how big the ground height difference of the base layer 3 is, the rectangular four-sided head 2223 at the top of the inverted T-shaped support screw 22 is always completely exposed above the cube four-sided head 233, ensuring the rapid progress of the leveling and fixing and locking processes.

[0139] 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, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit 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 this application.

[0140] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. 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.

[0141] The specific implementation of the present application is described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0142] like Figure 1 to Figure 21 As shown, an embodiment of the present application provides a universal indoor and outdoor nailless sports wooden floor; the universal indoor and outdoor nailless sports wooden floor includes: a floor module 1, a leveling hole blocking plate 111 and an elastic eccentric supporter 2; the elastic eccentric supporter 2 is arranged on a base layer 3, connecting and supporting the floor module 1 and the leveling hole blocking plate 111.

[0143] The floor module 1 and the leveling hole plugging plate 111 are made of a plastic material made of high-molecular polyethylene, wood powder, fiber and other additives, which are uniformly mixed and stirred. After granulation, they are melted into a semi-fluid state at high temperature and placed in a special die-casting mold for the integrated molded floor module in a three-beam four-column hydraulic press with a pressure of ≥500T. The high-molecular composite wood-plastic floor is obtained by one-time molding under the strong pressure of the hydraulic press; it 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 high-molecular composite wood-plastic, wood-plastic flooring has been 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.

[0144] 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.

[0145] like Figure 2 , Figure 4 , Fig.11 , Figure 14~Figure 17 As shown, the main leveling hole 11, and the left front corner secondary leveling hole 112, the right front corner secondary leveling hole 113, the left rear corner secondary leveling hole 115, the right rear corner secondary leveling hole 114, the front secondary leveling hole 116, the rear secondary leveling hole 117, the left secondary leveling hole 118, and the right secondary leveling hole 119 are arranged on the edge of the panel 10; when multiple floor modules 1 are assembled on the edge of the panel 10, the multiple secondary leveling holes on the edge of the adjacent panels 10 form a docking and combining leveling hole of the same size as the main leveling hole 11; The main fixing seat 121 and the circular main mounting hole 1211 below the main leveling hole 11; the left front corner fixing seat 132 and the left front corner secondary mounting hole 1321, the right front corner fixing seat 142 and the right front corner inclined secondary mounting hole 1421, the left rear corner secondary fixing seat 133 and the left rear corner inclined secondary mounting hole 1331, the right rear corner fixing seat 143 and the right rear corner secondary mounting hole 1431, the front secondary fixing seat 122 and the front secondary mounting hole 1221, the left secondary fixing seat 131 and the left secondary mounting hole 1311, the right secondary fixing seat 141 and the right inclined secondary mounting hole 1411, the rear secondary fixing seat 123 and the rear inclined secondary mounting hole 1231 below the secondary leveling hole; multiple secondary fixing bases and multiple secondary mounting holes, under the docking and leveling holes, form a docking and fixing seat with the same size as the main fixing seat, and the docking and mounting holes, which are convenient for the tray 24 and the buckle cover 25 to carry and accommodate.

[0146] Through the arrangement of the above-mentioned main leveling holes 11 and secondary leveling holes, it is ensured that after the multiple floor modules 1 are assembled in the front-to-back and left-to-right horizontal directions, the leveling hole blocking plate 111 of a single size specification blocks the main leveling hole 11 and the docking leveling hole, so that the present application obtains a complete and flat large surface required for sports; on the other hand, it is ensured that the present application can realize the leveling, locking, fixing and supporting of the floor module 1 by the elastic eccentric supporter 2 on the upper surface of the panel 10 of the floor module 1;

[0147] By setting the above-mentioned main fixing seat 121, secondary fixing seat and secondary mounting hole, it is ensured that after the multiple floor modules 1 are assembled in the front-back and left-right horizontal directions, the tray 24 and the buckle cover 25 of a single size specification are buckled into an inner cavity to accommodate the main fixing seat 121 or the docking fixing seat, so that the elastic eccentric supporter 2 can support the single floor module 1 below the single floor module 1 and support the multiple floor modules 1 below the edges of the panels 10 adjacent to the multiple floor modules 1; by connecting and locking the docking fixing seat below the docking leveling hole, the multiple floor modules 1 as separate individuals are connected and locked, so that the present application can obtain the large-area floor venue required for sports.

[0148] like Figure 11~Figure 18 As shown, the length and width of the upper plane of the main fixing seat 121 are smaller than the length and width of the main leveling hole 11; correspondingly, the length and width of the upper plane of the docking fixing seat are smaller than the length and width of the docking leveling hole; through this arrangement, it is convenient to put the buckle cover 25, the gasket clamp plate 26, and the hexagonal nut 27 downward from the main leveling hole 11 or the docking leveling hole to complete the accommodation of the main fixing seat 121 or the docking fixing seat, and complete the buckle with the tray 24, thereby realizing the connection, fixation, locking and support of the floor module 1 and the edges of the adjacent panels 10 of multiple floor modules 1 by the elastic eccentric supporter 2.

[0149] Such as 12, Fig.13 , Fig.18 As shown, the space between the upper surface of the main fixing seat 121 and the main leveling hole 11, and the space between the upper surface of the docking fixing seat and the docking leveling hole are used to accommodate the upper plate of the buckle cover 25, the gasket clamping plate 26, the hexagonal nut 27 and the leveling hole sealing plate 111. Through this arrangement, the upper plate of the buckle cover 25, the gasket clamping plate 26, and the hexagonal nut 27 will not affect the leveling hole sealing plate 111 to block the main leveling hole 11 and the docking leveling hole, so that the present application can obtain a complete and flat large surface required for sports.

[0150] like Figure 8 , Fig. 9 , Fig.13As shown, the high-frequency gravity, impact force, vibration, and offset force of sports fitness exercises will be repeatedly transmitted to the main fixing seat 121 and the docking and coupling fixing seat. The buckle cover 25, as the main component for accommodating, restricting, and constraining the main fixing seat 121 and the docking and coupling fixing seat, directly affects the long-term stable support of the elastic eccentric support 2 for the entire floor system. The large accommodating openings 252 symmetrically arranged on the vertical plates on both long sides of the buckle cover 25 weaken the overall strength of the buckle cover 25 to a certain extent, making the upper plate of the buckle cover 25 above the large accommodating opening 252 the weakest part of the buckle cover 25. The bottom plate of the gasket clamping plate 26 acts as a gasket for the hexagonal nut 27, making the locking force of the hexagonal nut 27 spread more evenly on the upper plate of the buckle cover 25. Second, the U-shaped shape formed by the bottom plate of the gasket clamping plate 26, the clamping plates 261 on both sides of the bottom plate, and the clamping heads at the upper ends of the two side clamping plates 261 that are inclined downward at 45° inward gives the gasket clamping plate 26 strong anti-deformation ability. The gasket clamping plate 26 is fixedly connected to the buckle cover 25 by spot welding on the upper plane of the upper plate of the buckle cover 25, directly enhancing the strength and anti-deformation ability of the upper plate of the buckle cover 25 and the buckle cover 25 itself, and forming a greater gain for the long-term stable support of the elastic eccentric support 2 for the entire floor system.

[0151] As Figure 2 , Figure 4 , Fig.11 , Figure 14~Figure 17 As shown, the support platform 101 is used to respectively abut against both sides of the back of the leveling hole plugging plate 111 when the leveling hole plugging plate 111 plugs the main leveling hole 11, providing support for the leveling hole plugging plate 111; when the leveling hole plugging plate 111 plugs the docking and coupling leveling hole, it respectively abuts against both sides of the leveling hole plugging plate 111, providing support for the leveling hole plugging plate 111; through the settings of the left support platform 1011 and the right support platform 1012, after multiple floor modules 1 are assembled horizontally left and right, the left support platform 1011 and the right support platform 1012 form a docking and coupling support platform of the same size as the support platform 101, providing support for the leveling hole plugging plate 111 when the leveling hole plugging plate 111 plugs the docking and coupling leveling hole.

[0152] As Figure 7 , Fig.18As shown, two symmetrical card slot support protrusions 1111 are provided on the back of the leveling hole plugging plate 111, and a recessed fastening card slot 1112 is provided on the outer vertical surface, corresponding to the card head of the gasket card plate 26, the length of the fastening card slot 1112 is the same as the length of the card slot support protrusion 1111, and the two corners on the outer side of the bottom surface are inclined surfaces; when installing the leveling hole plugging plate 111, the two card slot support protrusions 1111 of the leveling hole plugging plate 111 are downwardly directed and placed into the leveling hole in accordance with the direction of the two card plates 261, so that the two card slot support protrusions After the two inclined surfaces on the outer side of the bottom surface of the protrusion 1111 butt against the 45° inclined surfaces on the upper edges of the clamping heads of the two clamping plates 261, you only need to step on the upper plane of the leveling hole blocking plate 111 with your feet, so that the 45° inclined clamping heads on the top of the clamping plates 261 on both sides can be pushed outward by the clamping groove supporting protrusion 1111, and then smoothly slide into the fastening clamping groove 1112 on the outer side vertical surface of the clamping groove supporting protrusion 1111, so as to complete the clamping and fixing of the leveling hole blocking plate 111, and realize the simple, easy and fast installation of the leveling hole blocking plate 111;

[0153] like Figure 7 As shown, the length of the fastening slot 1112 is the same as the length of the slot supporting protrusion 1111, and the clamping head of the gasket clamping plate 26 is completely embedded in the fastening slot 1112, which maximizes its role in clamping and fixing the leveling hole blocking plate 111; the opening of the outer facade of the fastening slot 1112 is a trapezoid with a large outer opening, a small inner bottom surface, and upper and lower inclined surfaces. After the clamping heads on both sides of the gasket clamping plate 26 slide in, the upper inclined surface of the fastening slot 1112 does not hinder the sliding of the clamping heads and does not affect The clamping head plays a clamping role on the leveling hole plugging plate 111; the lower inclined surface with a low outer side and a high inner side makes the clamping heads on both sides slide into the corresponding fastening slots 1112 and contact the lower inclined surface, not only clamping and fixing the leveling hole plugging plate 111, but also because the clamping heads on both sides squeeze the inclined surface inward, a downward pulling force on the leveling hole plugging plate 111 is generated on the lower inclined surface; the clamping and fixing of the leveling hole plugging plate 111 and the downward pulling of the leveling hole plugging plate 111 make the elastic eccentric support 2 form a direct contact with the leveling hole plugging plate 111 The connection, fixation and locking prevent the leveling hole blocking plate 111 from loosening upward under any force; after the leveling hole blocking plate 111 blocks the main leveling hole 11 or the docking leveling hole, the two side planes on the back side and the support platform 101, or the docking support platform of the left support platform 1011 and the right support platform 1012 offset each other to produce a supporting effect, and the lower planes of the two slot support protrusions 1111 on the back side and the upper plane of the gasket card plate 26 also offset each other to produce a supporting effect. The double support makes the gravity and impact force occurring on the leveling hole blocking plate 111 be directly transmitted to each arch support through the support platform to disperse to the periphery, and directly transmitted to the elastic eccentric support 2 by the lower plane of the slot support protrusion 1111 to disperse downward, so as to avoid the leveling hole blocking plate 111 as a single individual from falling off and being damaged due to gravity and impact force, thereby realizing the use surface of the present application, which is used for the integrity, flatness, firmness, durability and reliability required for sports competitive fitness activities.

[0154] like Figure 4 , Figure 5 , Figure 6 As shown, the upper ends of the main arch support 12, the left arch support 13, and the right arch support 14 are connected to the panel 10, and the front and rear ends are connected between the main fixing seats 121 and the secondary fixing seats; the main arch support 12 is connected to the main fixing seat 121, the front fixing seat 122, and the rear fixing seat 123 at the front and rear ends; the left arch support 13 is connected to the left fixing seat 131, the left front corner fixing seat 132, and the left rear corner fixing seat 133 at the front and rear ends; the right arch support 14 is connected to the right fixing seat 141, the right front corner fixing seat 142, and the right rear corner fixing seat 143 at the front and rear ends; the middle position between the main fixing seats 121 and the secondary fixing seats is the highest position where the curved surface arches upward; and the starting position of the curved surface arching and the visible thickest position are connected to the main fixing seat 121 and the secondary fixing seats;

[0155] Furthermore, the main arch support 12, the left arch support 13, and the right arch support 14, as the main supports on the back of the present application, have an arched setting so that the impact of the force on the upper plane can be better dispersed and transmitted to the fixed seats on both sides, and then transmitted to the elastic eccentric support 2 by the fixed seats; as an arched anti-deformation setting, it is evenly distributed on the back of the floor module 1 at equal intervals, which helps the floor module 1 to maintain long-term anti-deformation ability under the large amount of intensive and continuous gravity impacts generated by sports, competitive fitness activities; using the arch as the main support saves materials and reduces material costs compared to the rectangle.

[0156] like Figure 2~Figure 5 , Fig.19 As shown, the first left limiting protrusion 134 and the second left limiting protrusion 136 are provided with a ┒-shaped inclined surface occupying the outer side of the upper plane, the rear end of the outer facade, and the outer side of the rear facade; the first left limiting recess 135 and the second left limiting recess 137 are provided with a front end facade inclined surface occupying the outer side of the front end facade; the first right limiting protrusion 145 and the second right limiting protrusion 147 are provided with a ┎-shaped inclined surface occupying the outer side of the upper plane, the front end of the outer facade, and the outer edge of the front facade; the first right limiting recess 144 and the second right limiting recess 146 are provided with a rear end facade inclined surface occupying the outer side of the rear end facade;

[0157] like Figure 3~Figure 6 , Figure 14~Figure 17 As shown, the rear ends of the right front corner inclined secondary mounting hole 1421 of the right front corner fixing seat 142 and the right inclined secondary mounting hole 1411 of the right fixing seat 141 are both provided with inclined vertical surfaces;

[0158] The left rear corner inclined secondary mounting hole 1331 of the left rear corner fixing seat 133 and the rear inclined secondary mounting hole 1231 of the rear fixing seat 123 are both provided with inclined vertical surfaces on the left side;

[0159] The distance between the rear limiting protrusion 18 and the front limiting protrusion 17 after the offset connection is at least twice the width of the left limiting protrusion 134 protruding from the outer facade of the left arch support 13;

[0160] Without the above configuration, the floor module 1 cannot be assembled and docked over a large area; Fig.21 As shown, the floor module 1 is installed in a large area. When the second floor module 1 of the second route is assembled, the elastic eccentric shaft seat 21, the inverted T-shaped support screw 22, the inverted T-shaped adjustment nut 23 and the tray 24 have been installed to the front end of the first floor module 1 of the second route and the respective secondary fixing seats on the left side of the first floor module 1. At this time, the second floor module 1 of the second route needs to be connected to the front end of the first floor module 1 of the second route at the rear end and the left side of the third floor module 1 at the right side.

[0161] Each secondary fixing seat at the rear end of the second floor module 1 of the second road needs to be on the front of each secondary fixing seat at the front end of the first floor module 1 of the second road and on the flat surface of the bottom plate of the tray 24, and then pushed back to complete the front-to-back direction docking; each secondary fixing seat on the right side of the second floor module 1 of the second road needs to be on the left side of each secondary fixing seat on the left side of the first floor module 1 and on the upper surface of the tray 24, and then pushed right to complete the left-right direction docking;

[0162] At this time, the long barrel nut 232 at the secondary mounting hole of each secondary fixing seat at the front end of the second-row first floor module 1 will collide with the right edge of the secondary mounting hole of the rear fixing seat 123 and the left rear corner fixing seat 133 at the rear end of the second-row second floor module 1 and the outer vertical surface of the rear fixing seat 123 and the left rear corner fixing seat 133, forming an assembly conflict in the front-to-back direction; the front-to-back direction docking cannot be completed by pushing the second-row second floor module 1 backward;

[0163] The long barrel nut 232 at the secondary mounting hole of each secondary fixing seat on the left side of the first floor module 1 also abuts against the outer vertical surface beside the rear edge of the secondary mounting hole of the right fixing seat 141 and the right front corner fixing seat 142 of the second floor module 1, forming a left-right assembly conflict; the left-right connection cannot be completed by pushing the second floor module 1 to the right;

[0164] The left side of each limiting protrusion of the first floor module 1 has a rear end of the facade that conflicts with the outer edge of the front end facade of each limiting recess on the right side of the second floor module 1; the outer edge of the rear end facade of each limiting recess conflicts with the front end edge of the facade of each limiting protrusion on the right side of the second floor module 1, and a corresponding connection cannot be made, resulting in a left-right assembly conflict;

[0165] Furthermore, the right side bevels of the second floor module 1, the left rear corner fixing seat 133 and the rear fixing seat 123 secondary mounting holes are set to eliminate the edge conflict of the long barrel nuts 232 at the front end of the first floor module 1 of the second road; the right side bevels of the second mounting holes of the right fixing seat 141 and the right front corner fixing seat 142 are set to eliminate the edge conflict of the long barrel nuts 232 on the left side of the first floor module 1;

[0166] Furthermore, the ┒-shaped inclined surface setting of each limiting protrusion on the left side of the first floor module 1 and the front end vertical surface inclined surface of each limiting recess eliminate the edge conflict with each limiting protrusion and each limiting recess on the right side of the second floor module 1 of the second road; the ┎-shaped inclined surface of each limiting protrusion on the right side of the second floor module 1 of the second road and the rear end vertical surface inclined surface of each limiting recess further eliminate the edge conflict with each limiting protrusion and each limiting recess on the left side of the first floor module 1;

[0167] Furthermore, the spacing between the front limiting protrusion 17 and the rear limiting protrusion 18 after the staggered connection is at least twice the width of the left limiting protrusion 134 protruding from the left side elevation of the floor module 1 and the outer side elevation of the left arch support 13. Therefore, the front limiting protrusion 17 and the rear limiting protrusion 18 will not have any influence on the corresponding connection between each limiting protrusion and each limiting recess, whether before or after the staggered connection.

[0168] At this time, it is only necessary to apply a push force to the second floor module 1 in the right and rear direction, so that the right side and the rear end can be assembled and docked with the left side of the first floor module 1 and the front end of the second floor module 1;

[0169] Furthermore, the inclined surface of the inclined secondary installation hole, the protruding ┒-shaped inclined surface and the ┎-shaped inclined surface, and the limiting recessed inclined surface are arranged to avoid or reduce corner collisions when multiple floor modules 1 are assembled.

[0170] like Figure 2~Figure 5 , Fig.19 As shown, each limiting protrusion and each limiting recess are located at the lower edge of the panel 10, and the strength of the panel 10 as the upper end bearing body of the floor module 1 is not damaged; when multiple floor modules 1 are assembled in the left and right horizontal directions, the left arch support 13 and the right arch support 14 are also combined into a docking combined arch support of the same size as the main arch support 12, and at the same time, the left limiting protrusion, the left limiting recess and the right limiting recess, the right limiting protrusion are also correspondingly connected, thereby forming a mutual connection support of the left arch support 13 and the right arch support 14;

[0171] Furthermore, when an athlete walks, runs, jumps, or steps on the upper surface of the panels 10 of two adjacent floor modules 1 that have been assembled in the left and right directions, and the soles of the feet generate downward gravity and impact force on the side of the left arch support 13 along the edge of the adjacent panel 10, the gravity and impact force transmitted to the left arch support 13 are supported by the right limit protrusion of the right arch support 14 and the left limit recess of the left arch support 13, and are jointly borne by the left arch support 13 and the right arch support 14, so as to avoid the left arch support 13 bearing the gravity and impact force alone, so that the panel on the side of the left arch support 13 is not affected. 10, generating instantaneous deformation and tremor frequency different from the side of the right arch support 14, ensuring that the edges of the adjacent panels 10 of the two floor modules 1 assembled and connected in the left and right directions, and the upper surface of the floor on both sides of the edges of the adjacent panels 10 are always in the same state, so as to avoid that the edges of the adjacent panels 10 in the left and right directions of the adjacent floor modules 1, and the upper surface of the floor on both sides of the edges of the adjacent panels 10, have different horizontal heights, and the soles of athletes are prevented from bumping and endangering personal safety, and different instantaneous deformation and tremor frequencies affect the performance of skills during fierce competitive sports;

[0172] Furthermore, when an athlete walks, runs, jumps, or steps on the upper surface of the panels 10 of two adjacent floor modules 1 that have been assembled in the left and right directions, and the soles of the feet generate downward gravity and impact force on the side of the right arch support 14 along the edge of the adjacent panel 10, the gravity and impact force transmitted to the right arch support 14 are supported by the left limit protrusion of the left arch support 13 and the right limit recess of the right arch support 14, and are jointly borne by the right arch support 14 and the left arch support 13, so as to avoid the right arch support 14 bearing the gravity and impact force alone, so that the panel on the side of the right arch support 14 is not tilted. 10 upper surface, generating instantaneous deformation and tremor frequency different from the left arch support 13 side; ensuring that the edges of the adjacent panels 10 of the two floor modules 1 assembled and connected in the left and right directions, and the floor upper surface on both sides of the edges of the adjacent panels 10 are always in the same state, so as to avoid athletes in fierce competitive sports from having shoe soles bumping and endangering personal safety, and different instantaneous deformation and tremor frequencies affecting technical performance due to different horizontal heights of the edges of the adjacent panels 10 in the left and right directions of the adjacent floor modules 1 and the floor upper surface on both sides of the edges of the adjacent panels 10;

[0173] Furthermore, due to the connection support, the gravity and impact force generated on the upper surface of the panel 10 on the right arch support 14 side are transmitted by the right arch support 14 to the right fixing seat 141, the right front corner fixing seat 142, and the right rear corner fixing seat 143 connected thereto, and are also transmitted by the left arch support 13 to the left fixing seat 131, the left front corner fixing seat 132, and the left rear corner fixing seat 133 connected thereto, thereby reducing and dispersing the gravity and impact force received and borne by the right fixing seat 141, the right front corner fixing seat 142, and the right rear corner fixing seat 143 on the right arch support 14 side, which is beneficial to the long-term system stability and anti-deformation ability of the floor module 1;

[0174] Furthermore, due to the connection support, the gravity and impact force generated on the upper surface of the panel 10 on the side of the left arch support 13 are transmitted by the left arch support 13 to the left fixing seat 131, the left front corner fixing seat 132, and the left rear corner fixing seat 133 connected thereto, and are also transmitted by the right arch support 14 to the right fixing seat 141, the right front corner fixing seat 142, and the right rear corner fixing seat 143 connected thereto; the gravity and impact force received and borne by the left fixing seat 131, the left front corner fixing seat 132, and the left rear corner fixing seat 133 on the side of the left arch support 13 are reduced and dispersed, which is beneficial to the long-term system stability and anti-deformation ability of the floor module 1;

[0175] Furthermore, the left arch support 13 and the right arch support 14 and the connected fixing seats jointly bear the gravity and impact force applied from the edge and both sides of the edge of the upper adjacent panel 10, and transmit the gravity and impact force to the connected elastic eccentric support 2 at the same vibration frequency and vibration frequency through the left fixing seat 131, the left front corner fixing seat 132, the left rear corner fixing seat 133, and the docking combination fixing seat of the right fixing seat 141, the right front corner fixing seat 142, and the right rear corner fixing seat 143. 2 is transmitted to the ground, and the shock absorption and rebound reaction force generated by the elastic rubber pad 211 in the gravity and impact force are fed back to each docking and fixing seat, and each docking and fixing seat evenly feeds back to the left arch support 13 and the right arch support 14; the edges of the adjacent panels 10 in the left and right horizontal directions of two adjacent floor modules 1 and the upper surface of the floor on both sides of the edges of the adjacent panels 10 present the same shock absorption and rebound reaction, ensuring that the edges of the adjacent panels 10 of multiple floor modules 1 and both sides of the edges of the adjacent panels 10 present the same physical and mechanical properties;

[0176] Furthermore, when the edges of the adjacent panels 10 in the horizontal direction of two adjacent floor modules 1 and the upper surface of the floor on both sides of the edges of the adjacent panels 10 generate downward gravity and impact force, due to the integrated structure of the floor module 1, the gravity and impact force are also dispersed and transmitted to the surroundings, and the left arch support 13, the right arch support 14 and the secondary fixing seats connected thereto do not bear all the gravity and impact force;

[0177] Furthermore, when athletes walk, run, and jump on the upper surfaces of the panels 10 of two adjacent floor modules 1 that have been assembled in the left and right directions, the friction, rubbing, sudden stop, sudden turn, and force exerted by the soles of their feet on the upper surfaces of the panels 10 of the floor modules 1 will not only generate vertical downward gravity and impact force, but also generate downward oblique gravity and impact force in multiple directions; the limit protrusions and the limit recesses correspond to the limit generated by the connection, preventing the left arch support 13 and the right arch support 14 that are connected in the left and right directions from being misaligned and displaced in the front and back directions, and at the same time preventing downward oblique gravity and impact force from multiple directions, all of which are concentrated on the left arch support 13, the right arch support 14, their respective secondary fixing seats, and the single docking combined fixing seat;

[0178] Furthermore, under the influence of uncontrollable environmental factors such as outdoor temperature, humidity, weather, and climate, since the sizes of the left arch support 13 and the right arch support 14 are only half of the main arch support 12, the probability of deformation of the left arch support 13 and the right arch support 14 is twice the probability of deformation of the main arch support 12; for example, when one side of the left arch support 13 generates an upward arching deformation force under the influence of uncontrollable environmental factors, due to the limiting effect of the limiting recess of the right arch support 14 on the limiting protrusion of the left arch support 13, the upward force on the side of the left arch support 13 is suppressed and restricted by the side of the right arch support 14, thereby limiting the upward arching deformation of one side of the left arch support 13;

[0179] Furthermore, when one side of the right arch support 14 generates an upward arch deformation force under the influence of uncontrollable environmental factors, due to the limiting effect of the limiting recess of the left arch support 13 on the limiting protrusion of the right arch support 14, the upward force of the right arch support 14 is suppressed and restricted by the left arch support 13, thereby limiting the upward arch deformation of the left arch support 13.

[0180] Furthermore, when the left arch support 13 generates a force for downward concave deformation under the influence of uncontrollable environmental factors, the force for the downward deformation of the left arch support 13 is offset and restricted by the right arch support 14 due to the limiting support of the limiting protrusion on the right arch support 14 on the left arch support 13, thereby limiting the downward concave deformation of the left arch support 13.

[0181] Furthermore, when one side of the right arch support 14 generates a force for downward concave deformation under the influence of uncontrollable environmental factors, due to the limiting support effect of the limiting protrusion of the right arch support 14 on the limiting concave of the left arch support 13, the force for the downward deformation of the one side of the right arch support 14 is offset and restricted by the one side of the left arch support 13, thereby limiting the downward concave deformation of the one side of the right arch support 14;

[0182] Furthermore, the limiting protrusions and limiting recesses of the left arch support 13 and the right arch support 14 are spaced apart by a limiting recess between two adjacent limiting protrusions; and spaced apart by a limiting protrusion between two adjacent limiting recesses, and are arranged in an interlaced manner, supported in an interlaced manner, and clamped in an interlaced manner to form an integrated effect; the limiting protrusions are in the cavity of the limiting recesses, and the two adjacent limiting protrusions jointly limit the angle and spacing of the two limiting recesses, so there is no room for any deformation, and any force for upward and downward deformation can only be applied by forcing the limiting recesses to deform and squeeze the limiting protrusions, or by changing the angle and distance of the limiting recesses to break the limiting protrusions, so as to obtain deformation space by crushing or squeezing the limiting protrusions or collapsing the limiting recesses; therefore, in an integrated structure with the same material and the same production process, the probability of upward and downward deformation is greatly limited;

[0183] Furthermore, the butt-jointed fixing seat formed by the secondary fixing seats connected to the left arch support 13 and the right arch support 14, due to the mutual support and limitation of the left and right limiting protrusions and limiting recesses, the edges of the adjacent panels 10 of the adjacent floor modules 1 are always in the same horizontal state, avoiding the edges of the adjacent panels 10 being at different heights, and causing personal injuries to athletes who slip or fall in fierce competitions due to their bodies being at the edge of the adjacent panels 10;

[0184] Furthermore, the docking-combined fixing seat formed by the secondary fixing seats connected to the left arch support 13 and the right arch support 14 can avoid uneven and different up and down offset vibration reactions of gravity and impact force on each secondary fixing seat as a separate individual due to the mutual support and limitation of the left and right limiting protrusions and limiting recesses; the connection and locking limit of the tray 24 and the buckle cover 25 form mutual gain, ensuring the long-term and stable support of the elastic eccentric supporter 2 under the edges of the left and right adjacent panels 10 of the multiple floor modules 1; and forming an integrated structural effect of mutual gain, mutual restraint and mutual reinforcement for the multiple floor modules 1 spliced ​​in the left and right horizontal directions, thereby ensuring and promoting the integrity of the entire floor system required for sports, long service life, high deformation resistance, personal safety in competitive fitness sports, and uniform presentation of physical and mechanical properties.

[0185] like Figure 4 As shown, the arched reinforcing support 15 at the lower end of the floor module 1 and the back of the panel 10 has a curved arch height at an oblique position with the main arched support 12, which is lower than the arch surface of the main arched support 12 and higher than the lower surface of the main fixing seat 121, so as not to hinder the neat stacking and packaging of the floor module 1 after production, and is conducive to batch transportation;

[0186] The arched reinforcement support 15 is connected at an angle of 45 degrees at the lowest position of the arched curve and the highest position of the arched curve of the main arched support 12, which can also be regarded as the thinnest position, to strengthen the anti-bending ability of the main arched support 12 and reduce the vibration frequency of the thinnest position of the arched curve of the main arched support 12 when it is subjected to a rapid gravity impact; The arched reinforcement support 15 arranged at an angle of 45 degrees enhances the anti-deformation ability of the floor module 1 in the oblique, left-right and front-back directions; The arched reinforcement support 15 arranged at an angle of 45 degrees provides a constant connection between the left arched support 13 and the main arched support 12, each main arched support 12, and the main arched support 12 and the right arched support 14, thereby enhancing the integrated strength of the floor module 1;

[0187] Furthermore, the arched reinforcement support 15 arranged at an angle of 45° is arched at the lowest position of the curved surface and crosses the middle position of the left arched support 13 and the right arched support 14 on the left and right sides of the floor module 1, thereby strengthening the ability of the left arched support 13 and the right arched support 14 to resist bending and deformation toward the inner side of the back of the panel 10, and quickly conducts and disperses the gravity and impact force on the left arched support 13 and the right arched support 14 to the inner side of the floor module 1, thereby reducing the influence of gravity and impact force on the left arched support 13 and the right arched support 14;

[0188] Furthermore, the two ends of the arched reinforcement support 15 are located in the middle between the parallel main arched supports 12, between the arched support 13 and the main arched support 12, and between the right arched support 14 and the main arched support 12; the gravity and impact force between the arched supports on the upper surface of the panel 10 of the floor module 1 are directly transmitted by the arched reinforcement support 15 to the arched supports that are obliquely intersected with it, so as to avoid collapse and deformation between the parallel arched supports caused by long-term gravity impact; and the reaction force from the elastic eccentric supporter 2 is fed back to the upper surface of the panel 10 between the adjacent parallel arched supports; to avoid different shock absorption effects and rebound forces at the position with arched support and the position without arched support at the lower part 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;

[0189] The mutual gain between the multiple arched reinforcement supports 15 and the multiple left arched supports 13, the multiple main arched supports 12, and the multiple right arched supports 14 enhances the integrated strength of the floor module 1 and strengthens the overall load-bearing performance, impact resistance, and deformation resistance of the floor module 1.

[0190] like Figure 4As shown, the rectangular reinforcement support 16 at the lower end of the floor module 1 and the back of the panel 10 is connected to the left arch support 13, the main arch support 12, and the right arch support 14 at 45 degrees, and is connected to the two ends of the arch reinforcement support 15 at 90 degrees, thereby enhancing the anti-deformation ability of the floor module 1 in the oblique direction, left-right direction, and front-back direction; the rectangular reinforcement support 16 arranged at an oblique angle of 45 degrees constantly connects the left arch support 13 with the main arch support 12, the right arch support 14, and the arch reinforcement support 15, thereby improving the integrated strength of the floor module 1;

[0191] Furthermore, the rectangular reinforcing support 16 arranged at an angle of 45° is connected to the middle position of the left arch support 13 and the right arch support 14 on the left and right sides of the floor module 1, and together with the arch reinforcing support 15, supports and reinforces the left arch support 13 and the right arch support 14, thereby enhancing the anti-deformation ability of the left arch support 13 and the right arch support 14, and quickly conducts and disperses the gravity and impact force on the left arch support 13 and the right arch support 14 to the inner side of the floor module 1, thereby reducing the influence of gravity and impact force on the left arch support 13 and the right arch support 14; the mutual gain between the multiple rectangular reinforcing supports 16 and the multiple left arch supports 13, the multiple main arch supports 12, the multiple right arch supports 14, and the multiple arch reinforcing supports 15 further enhances the overall load-bearing performance, impact resistance, and anti-deformation ability of the floor module 1;

[0192] Furthermore, the gravity and impact force generated between the parallel arch supports on the upper surface of the panel 10 of the floor module 1 are directly transmitted to the connected arch reinforcement protrusions 15 and each arch support through the reinforcing support of the rectangular reinforcing support 16, so as to avoid collapse and deformation between the parallel arch supports caused by long-term gravity impact; and the reaction force from the elastic eccentric support 2 is fed back to the upper surface of the panel 10 between the adjacent arch supports, so as to avoid different shock-absorbing effects and rebound forces at the positions with arch supports and without arch supports below the upper surface of the panel 10, and reinforce each other with the arch reinforcement support 15, so as to further promote the uniform display of the elasticity and shock-absorbing function of the floor module 1.

[0193] As a benefit measure of the present application: steel bars are built into the rectangular reinforcement 16 and the main arch support 12, the left arch support 13, the right arch support 14 and the connected main fixing seats and secondary fixing seats to further improve and strengthen the longitudinal and lateral deformation resistance of the floor module 1 and improve the seismic resistance and tensile strength of the main fixing seats and secondary fixing seats; before the floor module 1 is molded, the steel bars are placed at the corresponding positions of the designated parts in the special molding mold of the floor module 1, and the steel bars can be built-in during normal molding production.

[0194] like Figure 2 , Figure 4 , Fig. 20 As shown, after the multiple floor modules 1 are assembled along the front and rear horizontal directions at the edge of the panel 10, the front limiting protrusion 17 and the rear limiting protrusion 18 are also staggered and connected; after the front limiting protrusion 17 and the rear limiting protrusion 18 are staggered and connected, when the upper plane on one side of the front limiting protrusion 17 generates gravity and impact force, the rear limiting protrusion 18 limits the deformation, vibration and vibration frequency of the upper plane on one side of the front limiting protrusion 17, driving the upper surface of the panel 10 on the side of the rear limiting protrusion 18 to generate the same deformation, vibration and vibration frequency as the side of the front limiting protrusion 17, and jointly bear and disperse the gravity and impact force with the side of the front limiting protrusion 17;

[0195] Furthermore, after the rear limiting protrusion 18 and the front limiting protrusion 17 are misaligned and connected, when the upper plane on one side of the rear limiting protrusion 18 generates gravity and impact force, the front limiting protrusion 17 limits the deformation, tremor and vibration frequency of the upper plane on one side of the rear limiting protrusion 18, driving the upper surface of the panel 10 on the side of the front limiting protrusion 17 to generate the same deformation, tremor and vibration frequency as the side of the rear limiting protrusion 18, and jointly bear and disperse the gravity and impact force with the side of the rear limiting protrusion 18; when the upper plane on one side of the front limiting protrusion 17 generates gravity and impact force, the rear limiting protrusion 18 jointly bears and quickly disperses and transmits it inward to the arched reinforcement support 15 and the rectangular reinforcement support 16 connected thereto, and the arched reinforcement The support 15 and the rectangular reinforcing support 16 are then quickly transmitted and dispersed to the connected arch supports, driving the upper surface of the panel 10 on the side of the rear limit protrusion 18 to produce the same deformation, tremor and vibration frequency as the side of the front limit protrusion 17; when the upper plane on the side of the rear limit protrusion 18 produces gravity and impact force, the front limit protrusion 17 bears them together and quickly disperses and transmits them inward to the arch reinforcing support 15 and the rectangular reinforcing support 16 connected thereto, and the arch reinforcing support 15 and the rectangular reinforcing support 16 are then quickly transmitted and dispersed to the connected arch supports, driving the upper surface of the panel 10 on the side of the front limit protrusion 17 to produce the same deformation, tremor and vibration frequency as the side of the front limit protrusion 17;

[0196] Furthermore, after multiple floor modules 1 are assembled along the front-to-back horizontal direction at the edge of the panel 10, the edges of the adjacent panels 10 of two adjacent floor modules 1 and the upper surface of the floor on both sides of the edges of the adjacent panels 10 always present the same deformation, tremor and vibration frequency when subjected to gravity and impact force; ensuring that the horizontality, instantaneous deformation and tremor frequency of the edges of the adjacent panels 10 of the two floor modules 1 assembled and docked in the front-to-back direction and the upper surface of the adjacent panels 10 on both sides are always in the same state, so as to avoid the athletes in fierce competitive sports from having different horizontal heights due to the edges of the adjacent panels 10 on the left and right edges of the adjacent floor modules 1 and the upper surface of the floor on both sides of the edges of the adjacent panels 10, causing shoe soles to collide and endanger personal safety, and different instantaneous deformation and tremor frequencies to affect technical performance;

[0197] Further, under the influence of uncontrollable environmental factors such as outdoor temperature, humidity, weather and climate, when one side of the front limit protrusion 17 generates an upward arching deformation force, due to the limiting effect of the rear limit protrusion 18 on the side of the front limit protrusion 17, the upward force on the side of the front limit protrusion 17 is suppressed and restricted by the side of the rear limit protrusion 18, thereby limiting the upward arching deformation of the side of the front limit protrusion 17; when one side of the rear limit protrusion 18 generates an upward arching deformation force under the influence of uncontrollable environmental factors, due to the limiting effect of the front limit protrusion 17 on the side of the rear limit protrusion 18, the upward force on the side of the rear limit protrusion 18 is suppressed and restricted by the side of the front limit protrusion 17, thereby limiting the upward arching deformation of the side of the rear limit protrusion 18;

[0198] Further, when one side of the front limit protrusion 17 generates a force for downward concave deformation under the influence of uncontrollable environmental factors, due to the limiting support effect of the rear limit protrusion 18 on the one side of the front limit protrusion 17, the force of the downward deformation of the one side of the front limit protrusion 17 is offset and restricted by the one side of the rear limit protrusion 18, thereby limiting the concave deformation of the one side of the front limit protrusion 17 downward; when one side of the rear limit protrusion 18 generates a force for downward concave deformation under the influence of uncontrollable environmental factors, due to the limiting support effect of the front limit protrusion 17 on the one side of the rear limit protrusion 18, the force of the downward deformation of the one side of the rear limit protrusion 18 is offset and restricted by the one side of the front limit protrusion 17, thereby limiting the concave deformation of the one side of the rear limit protrusion 18 downward;

[0199] Furthermore, due to the recessed opening, the panel 10 on both sides of the front leveling hole 116 and the rear leveling hole 117 of the floor module 1, on the right side of the left front corner leveling hole 112 and the left rear corner leveling hole 115, and on the left side of the right front corner leveling hole 113 and the right rear corner leveling hole 114 of the floor module 1 is slightly weak. The rear limit protrusion 18 reinforces the strength of the panel 10 on both sides of the front and rear leveling holes and the inner side of each corner leveling hole, and is integrally connected with the front limit protrusion 17 through the arched reinforcement support 15 and the rectangular reinforcement support 16, thereby jointly reinforcing the strength of both sides of the edges of the front and rear ends of the floor modules 1 adjacent to each other.

[0200] Furthermore, the front limiting protrusion 17 supports and limits the rear limiting protrusion 18, so that the edges of the adjacent panels 10 at the front and rear ends of the adjacent floor modules 1 and the upper surfaces of the floor on both sides of the edges are always in the same horizontal state, so as to avoid the edges of the adjacent panels 10 of the two adjacent floor modules 1 and the upper surfaces of the floor on both sides of the edges being at different heights, so as to prevent the athletes who slip or fall in fierce competition from being injured because their bodies are at the edge of the adjacent panels 10;

[0201] The front limiting protrusion 17 and the rear limiting protrusion 18 form an integrated structural effect of mutual enhancement, mutual restriction and mutual reinforcement for the multiple floor modules 1 assembled and connected in the front and rear horizontal directions, ensuring the integrity of the entire large-area floor system required for sports, long service life, high deformation resistance, personal safety in competitive fitness sports, and uniform presentation of physical and mechanical properties.

[0202] like Figure 1 , Figure 8 , Fig. 9 , Fig.13 As shown, the elastic eccentric supporter 2 is located below the main leveling hole 11 of the floor module 1, below the docking leveling holes of the multiple floor modules 1, and below the leveling hole blocking plate 111, to connect and support the multiple floor modules 1 and the leveling hole blocking plate 111, and supports the edges of the adjacent panels 10 of the multiple floor modules 1 by connecting and fixing the docking fixing seat below the edges of the adjacent panels 10 of the multiple floor modules 1, so that the multiple floor modules 1 as separate individuals are connected and locked to form a large venue and large plane required for sports in this application;

[0203] The corner limit baffle 243 of the tray 24 is combined with the elastic eccentric shaft seat 21, the inverted T-shaped support screw 22 and the inverted T-shaped adjustment nut 23, and is installed on a single secondary fixing seat. The corner limit baffle 243 is buckled on the inner corner of the secondary fixing seat, and the inverted T-shaped adjustment nut 23 passes through the secondary mounting hole of the secondary fixing seat. At this time, the elastic rubber pad 211 touches the ground to allow the inverted T-shaped adjustment nut 23 to support the tray 24, so that the tray 24 is close to the lower plane of the secondary fixing seat. At this time, due to the restrictions of the corner limit baffle 243 and the inverted T-shaped adjustment nut 23, when the buckle cover 25 is not installed, the tray 24 can only make extremely limited displacement under the action of external force; and at this time, the plane on the bottom plate of the tray 24 exposed outside the secondary fixing seat is an unobstructed plane, which is conducive to the smooth docking of other secondary fixing seats on the bottom plate plane with the secondary fixing seat to form a docking and combined fixing seat;

[0204] When the limit correction plate 251 of the buckle cover 25 is inserted downwardly into the corresponding limit correction opening 241, the two oblique sides on both sides of the triangle of the limit correction plate 251 correct the limited displacement of the tray 24 caused by vibration and contact with external forces by squeezing the edge of the limit correction opening 241, so that the bottom of the tray 24 is connected with the limit correction opening 241; and under the locking action of the hexagonal nut 27 and the inverted T-shaped adjustment nut 23, the misalignment between the tray 24 and the buckle cover 25 is mutually limited by the corner accommodation opening 253, so that the tray 24 and the buckle cover 25 can maintain long-term stable accommodation, locking and restriction on the main fixing seat 121 or the docking combined fixing seat in the inner cavity.

[0205] like Fig. 9 , Fig.10As shown, for the threaded connection of the elastic eccentric supporter 2 and the stable connection support with the floor module 1, the present application adopts two permanent anti-loosening settings, namely reverse thread and wedge locking; the inner hole thread of the long barrel nut 232 and the outer wall thread of the inverted T-shaped support screw 22 are corresponding left-handed coarse thread, and the outer wall thread thereof connected with the hexagonal nut 27 is right-handed coarse thread; the anti-loosening setting of the left-handed thread and the right-handed thread offsetting each other and restricting each other always ensures that the tray 24 and the buckle cover 25 are firmly buckled and not loose, so as to realize the long-term stable accommodation, locking, bearing, limiting and connection of the main fixing seat 121 and the docking fixing seat by the elastic eccentric supporter 2;

[0206] Furthermore, the inverted T-shaped support screw 22 is connected to the inverted T-shaped adjustment nut 23, and the gravity generated by the weight of the floor and the gravity, impact force and vibration generated by sports activities are all transmitted to the elastic rubber pad 211. The elastic rubber pad 211 and the repeated forces of instantaneous deformation, instantaneous recovery and instantaneous rebound of the elastic rubber pad 211 due to shock absorption and damping are converted into the elastic rubber pad 211 driving the inverted T-shaped support screw 22 to rotate clockwise upward along the thread in the inner hole of the inverted T-shaped adjustment nut 23 to generate a loosening and unloading force;

[0207] Furthermore, the oblique tooth tip of the flat-head triangular locking block 2222 is embedded in and cuts off the inner wall thread of the inverted T-shaped adjusting nut 23, and the portion where the long barrel nut 232 and the hexagonal nut 27 are connected is pushed outward and protrudes, changing from a round shape to an irregular shape, and the hexagonal nut 27 is completely stuck, so that the hexagonal nut 27 cannot rotate in any direction, and the gravity of the floor itself and any force generated by sports activities cannot loosen the hexagonal nut 27 and the inverted T-shaped adjusting nut 23, so that the inverted T-shaped supporting screw 22 is in the inner hole of the inverted T-shaped adjusting nut 23 along the left-handed thread Rotating upward clockwise will cause loosening and unloading, resulting in loss of support, forming a limit lock for the elastic eccentric shaft seat 21; the beveled teeth on the back of the beveled teeth are embedded in the inner wall threads of the inverted T-shaped adjusting nut 23, which can prevent the flat-headed triangular locking block 2222 from escaping from the locking groove 2221 under the impact and vibration generated by long-term physical activities; therefore, after leveling and fixing and locking, the elastic eccentric supporter 2 can maintain the long-term anti-loosening of the threaded connection setting, thereby maintaining the connection support for the floor module 1 for a long time, so that the use surface of this application is stably on the same horizontal plane for a long time.

[0208] like Figure 8 , Fig. 9 , Fig.23 , Fig.24 As shown, the elastic eccentric shaft seat 21 can drive the elastic rubber pad 211 through the eccentric shaft seat 213 to rotate around the axis 214 within a certain range, so that the bottom surface of the elastic rubber pad 211 conforms to the inclination angle of the base layer and fits the surface of the base layer on the base layer with a large inclination angle and a large height difference;

[0209] like Fig.25 As shown, the existing adjustable sports wood floor technology has no setting for rotation around the axis when supported on the base ground with large height difference and large inclination angle. The lower surface of the elastic rubber pad 211 or the leveling pad support point will be grounded on the high side and suspended on the low side on the base ground with large inclination angle and large height difference. The uneven force causes the support point to twist and deform, and the risk of damage is greatly increased; due to the uneven force, its shock absorption, shock absorption, elasticity and rebound performance will be discounted, affecting the human protection performance and physical and mechanical properties required for sports by the floor system, and reducing the use quality of the floor system; one side is grounded and the other side is suspended, the gravity force is uneven, and the risk of falling off, connection failure and damage is greatly increased. After bearing the weight of the floor itself and the gravity impact force generated by sports for a long time, the support point will fall off, the connection will fail, and it will be damaged, and the supporting function of the floor will be lost, which will cause the floor to be hollow and the physical and mechanical properties required for sports to be completely lost, endangering the personal safety of sports participants; it may even cause the entire floor system to be scrapped.

[0210] Fig.24 , Fig.25 , Fig.26 As shown in the figure, unlike the flat base ground, where the gravity generated by the floor's own weight and the gravity and impact force generated by athletes performing sports activities on the floor are only transmitted from top to bottom to the base ground: on the base ground with a large inclination angle and a large height difference, the gravity generated by the floor's own weight and the gravity and impact force generated by athletes performing sports activities on the floor are transmitted from top to bottom to the ground, and are also transmitted from the high point to the low point of the ground, generating an offset thrust from high to low on the floor system, which directly affects the stable support and service life of the support points; on the concrete base venues and marble base venues with a large inclination angle, the long-term offset thrust from high to low will cause the entire floor to slide from high to low along the inclination direction of the base ground.

[0211] Before leveling on a base floor with a large inclination angle and a large height difference, the present application adjusts the direction indicating arrow 2224 to point to the direction of high terrain, driving the side of the second half of the long side of the elastic eccentric shaft seat 21 to be in a high position, and the side of the third half of the long side of the elastic eccentric shaft seat 21 to be in a low position, so that the elastic eccentric shaft seat 21 can distribute the gravity and impact force to the elastic rubber pad 211 more reasonably, so that the elastic rubber pad 211 can evenly bear the gravity and impact force, and will not produce its own local deformation due to poor gravity distribution. The elastic rubber pad 211 fits the base floor to bear the gravity and impact force and make uniform feedback to the gravity and impact force, ensuring that the physical and mechanical properties such as shock absorption, shock absorption, elasticity and rebound required for sports are maintained for a long time, thereby ensuring the long service life and stable use quality of the floor system;

[0212] Furthermore, the eccentric setting of the elastic eccentric shaft seat 21 maximizes the contact area between the elastic rubber pad 211 and the base floor at a large inclination angle and a large height difference, thereby achieving a large friction resistance between the elastic rubber pad 211 and the base floor, offsetting and limiting the influence of the offset thrust, and ensuring the long-term and stable support of the floor module by the inverted T-shaped support screw 22.

[0213] By means of the eccentric setting of the elastic eccentric shaft seat 21, as well as the flexible adjustment of the size and volume of the elastic eccentric shaft seat 21 and the elastic rubber pad 211 and the size and specifications of the inverted T-shaped support screw 22, the present application can be applied to the fish-back-shaped site base with a large inclination angle set up for drainage needs on roofs and building roofs in urban areas with scarce land resources; on such base sites, the size and specifications of the inverted T-shaped support screw 22 are adjusted according to the height difference of the site to achieve the stable support of the present application and the flatness of the use surface; the roof / building roof is different from other bases and is a special bearing body with a space at the bottom. Therefore, the size and volume of the elastic eccentric shaft seat 21 and the elastic rubber pad 211 are adjusted and increased, and the contact area between the elastic rubber pad 211 and the roof and building base is increased, so as to reduce the load and impact pressure exerted on a single contact point by the gravity generated by the weight of the present application itself and the gravity and impact force generated by sports, thereby protecting the roof and building roof, which are special bearing bodies with a space at the bottom.

[0214] like Fig.23 As shown, during the specific installation of the present application, any one of the four sides of the site is selected, and the first road is installed by docking and assembling them piece by piece, and the second road is installed on the left side of the first road. After the installation of the second road is completed, the third road is installed on the left side of the second road, and the fourth road is installed on the left side of the third road. The installation of the floor module 1 of the entire site is gradually completed by assembling and docking on the left side of each road.

The inclined surface of the shaped inclined surface and the limiting recessed inclined surface is set to realize the large-area assembly of multiple floor modules 1; through the multiple limiting protrusions and limiting recesses, the connecting effect is played between each floor module 1, and the mutual positioning, limiting, and mutual support between adjacent floor modules 1 are realized, so that after the large-area paving of the present application, the edges of the adjacent panels 10 of each floor module 1 maintain uniform physical properties, improve the anti-deformation performance and personal safety factor of the edges of the adjacent panels 10 of each floor module 1, and strengthen the integration of the large area and large site of the floor module 1 as a separate individual; through the staggered setting, sequential locking and leveling hole setting between the leveling components and locking components of the elastic eccentric supporter 2, the limitation of the prior art that the leveling and leveling operation must be performed before the surface layer board / bearing board closes the keel is solved, and the precise connection, fixation, locking and permanent anti-loosening between the components are realized, and the floor use surface is leveled quickly and accurately; through the direction indication of the direction indication arrow 2224 and the elastic eccentric shaft seat 21 around the axis 214 can rotate within a certain range, adapt to various indoor and outdoor large-angle bases, large-height-difference uneven bases, and reasonably distribute gravity through eccentric settings, so that the elastic eccentric support 2 can stably support multiple floor modules 1 on various indoor and outdoor large-angle bases, large-height-difference uneven bases, so that the physical properties required for sports such as elastic shock absorption and shock reduction of the present application can be reasonably fed back and maintained for a long time on various indoor and outdoor large-angle bases, large-height-difference uneven bases; the present application does not use any nails for connection and fixation without nails, completely eliminating the existing sports wood floor technology in which multiple components are stacked and laid layer by layer, a large number of various nails are used between the components, a large number of cumbersome manual connection and fixation operations, a large number of nails are driven into the connection and fixation due to manual operations, and the connection and fixation risks caused by the probability of nail quality, a large workload of leveling, a large consumption of leveling materials, and difficulty in leveling, which affects the service life and quality of the floor, and the waste of after-sales maintenance materials and labor.The floor module 1 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 efficiency of material use, saves a large amount of solid wood and solid wood finished products in the existing sports wood floor technology, reduces the consumption of forest resources, and is conducive to the sustainable development of the ecological environment. ;
