Description

Technical Field

[0001] This invention belongs to the field of sports flooring technology, specifically a type of indoor and outdoor universal sports wood flooring that is easy to install and disassemble. Background Technology

[0002] A Chinese patent with publication number CN119754509A discloses a universal indoor and outdoor modular nail-free sports wood flooring, including a resilient floor module and a locking device. The resilient floor module has multiple support legs at its lower end. The locking device automatically locks and engages through a thrust-driven reset mechanism, permanently connecting, limiting, locking, and fixing adjacent support legs. This achieves permanent connection, limiting, locking, and fixing of adjacent resilient floor modules and enables large-area assembly and installation of the resilient floor modules, forming a large venue required for sports and fitness activities. This application can be used as a permanent facility, installed on flat surfaces in indoor and outdoor open-air areas of buildings where leveling of the floor is not required. The aforementioned prior art claims that compared to existing indoor and outdoor nail-free sports wood flooring technology, it lacks leveling holes, leveling hole sealing plates, and elastic eccentric supports (excluding elastic pads), resulting in a simpler structure, easier and faster installation, and the ability to be applied to flat surfaces that do not require leveling at a lower material and installation cost. However, in actual application, sports wood flooring is subjected to high-intensity sports activities for extended periods, inevitably leading to structural damage such as dents and deformations in some individual pieces. For intense high-intensity sports, any structural deformation can cause injuries such as sprained ankles for athletes. Therefore, if the above situation occurs during sports activities, the individual wood flooring pieces with structural damage should be replaced promptly. However, in the aforementioned existing technology, although the use of elastic eccentric supports can achieve easy disassembly and assembly between wooden floors, it cannot be directly applied to the scenario of replacing individual wooden floors in an assembled wooden floor. Therefore, when the above situation occurs, it is only possible to start disassembly from the edge of the assembled wooden floor until the wooden floor with structural damage is removed. Therefore, it is foreseeable that replacing individual wooden floors in the above manner will lead to an indefinite extension of maintenance time.

[0003] Therefore, the present invention provides an indoor and outdoor universal sports wood floor that is easy to disassemble and assemble. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies and address the issue that the sports wood flooring connection method proposed in the background technology cannot be directly applied to scenarios where individual wood floorboards need to be replaced in assembled wood flooring.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an indoor and outdoor universal easy-to-disassemble sports wood flooring, comprising a wooden floor and a quick-assembly / disassembly module; the quick-assembly / disassembly module is fixedly connected to the bottom of the wooden floor; The quick-assembly / disassembly module includes a base plate, a linkage rod, a movable plate, and a lead screw. The bottom of the lead screw is rotatably connected to the base plate via a bearing. The linkage rod and the lead screw are connected through the linkage rod. A ball nut is fixed to the center of the upper surface of the linkage rod, and the lead screw and the ball nut are threaded together. The movable plate is slidably connected to the base plate. Two movable plates are provided, and the two movable plates are arranged in a circumferential array around the lead screw. A slot is opened in the center of the inner side of the movable plate, and the linkage rod is engaged with the slot. When the linkage rod rotates, it drives the movable plate to move radially until both ends of the linkage rod are engaged in the slot, thus connecting adjacent wooden floorboards. An inspection hole is provided in the middle of the surface of the wooden floor, and the top of the screw rod passes through the inspection hole. When the wooden floor needs to be removed and replaced independently, the screw rod is exposed based on the inspection hole. The screw rod is rotated to deform and bend the two ends of the linkage rod and lift it up, disengaging it from the movable plate, so that the movable plate is reset and the connection with the adjacent wooden floor is canceled.

[0006] Preferably, the bottom of the wooden floor is fixedly connected to a liner, and the bottom of the liner is fixedly connected to a joist. The liner and the joist are symmetrically arranged on the bottom of the wooden floor, and the quick-release module is arranged between the two liners.

[0007] Preferably, a first insert rod is fixed to the outer side of the movable plate, and the first insert rod is distributed at both ends of the outer side of the movable plate. When the linkage rod rotates, it drives the movable plate to move radially, and the first insert rod on the movable plate moves to the bottom of the adjacent wooden floor and drives the joists at the bottom of the two adjacent wooden floor to come together.

[0008] Preferably, both ends of the keel are provided with connecting holes, and a locking rod is slidably connected in the connecting holes. Both ends of the locking rod are provided with triangular blocks, and a first spring is also sleeved on the locking rod. The two ends of the first spring are respectively fixed between the side wall of the keel and the triangular blocks. The first spring is used to drive the locking rod to move radially towards the outer edge of the wooden floor.

[0009] Preferably, a second insert rod is also fixed to the outer side of the movable plate, and the end of the second insert rod is provided with an inclined surface relative to the triangular block on the locking rod; The first insert rod has an insertion hole. When the movable plate is radially displaced under the pressure of the linkage rod, the second insert rod presses the triangular block, causing the locking rod to radially displace toward the center of the wooden floor and engage with the insertion hole on the first insert rod.

[0010] Preferably, the quick-assembly module further includes a limiting plate, which is fixedly connected to the base plate, and the limiting plate has a limiting groove and a deformation groove respectively relative to the movable plate and the lead screw; A slider is fixedly connected to the movable plate relative to the limiting groove, and the slider is slidably connected in the limiting groove. The lead screw passes through the middle of the deformation groove.

[0011] Preferably, connecting rods are fixedly connected to the top of both ends of the base plate, and the connecting rods pass through the limiting plate. A baffle is also fixedly connected to the base plate. When the connecting rod rotates to be perpendicular to the movable plate, the baffle restricts the connecting rod from continuing to rotate.

[0012] Preferably, a straight rod is connected through the side wall of the limiting plate, and nuts are threaded to both ends of the straight rod. The straight rod passes through the slider, and a second spring is also sleeved on the straight rod. The two ends of the second spring are respectively fixed between the side wall of the limiting plate and the side wall of the slider.

[0013] Preferably, the bottom of the wooden floor is provided with a fixing plate, and the fixing plate is configured as an I-beam. The top of the fixing plate is snapped between the limiting plate and the liner, and the bottom of the fixing plate is fixedly connected to the limiting plate and the liner.

[0014] Preferably, it also includes a maintenance tool, wherein a slotted notch is provided on the top of the ball nut, and the maintenance tool passes through the maintenance hole and engages with the slotted notch on the top of the ball nut to drive the ball nut and the linkage rod to rotate, and a maintenance cap is engaged in the maintenance hole.

[0015] The beneficial effects of this invention are as follows: The present invention discloses an indoor and outdoor universal easy-to-disassemble sports wood flooring. By controlling the rotation of ball nuts and linkage rods, the linkage rods in the quick-release module at the bottom of the wood flooring can rotate and squeeze the movable plate during rotation. This causes the movable plate to move radially outward within the quick-release module. After the movable plate moves radially, it can limit the two adjacent spliced ​​wood floorings on the upper layer, thereby making the two adjacent spliced ​​wood floorings on the upper layer tightly connected. When it is necessary to remove the wood flooring, it is only necessary to release the linkage rods in the corresponding wood flooring that are squeezing the movable plate, and release the linkage rods in the four wood floorings adjacent to the wood flooring to be removed, so that the wood flooring to be removed can be taken out. The quick-release module enables the tight connection of adjacent wood floorings. At the same time, the quick-release module also enables the individual wood flooring to be removed from the overall wood flooring without removing the entire wood flooring when it needs to be replaced.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 10 As shown in the figure, an indoor and outdoor universal easy-to-disassemble sports wood flooring according to an embodiment of the present invention includes a wooden floor 1 and a quick-installation module 2; the quick-installation module 2 is fixedly connected to the bottom of the wooden floor 1; The quick-assembly / disassembly module 2 includes a base plate 21, a linkage rod 24, a movable plate 23, and a lead screw 25. The bottom of the lead screw 25 is rotatably connected to the base plate 21 via a bearing. The linkage rod 24 is through-fitted with the lead screw 25. A ball nut 241 is fixedly connected to the middle of the upper surface of the linkage rod 24, and the lead screw 25 is threadedly fitted with the ball nut 241. The movable plate 23 is slidably connected to the base plate 21. Two movable plates 23 are provided, and the two movable plates 23 are arranged in a circumferential array around the lead screw 25. A slot 235 is opened in the middle of the inner side of the movable plate 23, and the linkage rod 24 is engaged with the slot 235. When the linkage rod 24 rotates, it drives the movable plate 23 to move radially until both ends of the linkage rod 24 are engaged in the slot 235, thus connecting adjacent wooden floorboards 1. An inspection hole 13 is provided in the middle of the surface of the wooden floor 1, and the top of the screw 25 passes through the inspection hole 13. When the wooden floor 1 needs to be removed and replaced independently, the screw 25 is exposed based on the inspection hole 13. The screw 25 is rotated to deform and bend the two ends of the linkage rod 24 and lift it up, so as to disengage from the movable plate 23, so that the movable plate 23 is reset and the connection with the adjacent wooden floor 1 is canceled.

[0020] In existing technologies, the splicing of conventional sports wood flooring mainly relies on hardware and specially customized clamping mechanisms. In practical applications, the only advantage of this splicing method is ease of assembly and disassembly. However, this ease of assembly and disassembly is limited to overall assembly and disassembly. During application, if the assembled sports wood flooring suffers structural damage and deformation, the deformed flooring cannot be removed independently; the entire floor must be disassembled. This results in a lengthy repair process, which is undoubtedly fatal for competitive sports. Therefore, in one embodiment of this invention, when installing wooden flooring 1, the quick-assembly / disassembly module 2 located at the bottom of wooden flooring 1 can connect adjacent wooden flooring 1s sequentially to complete the connection of the entire wooden flooring 1. Specifically, when connecting adjacent wooden flooring 1s using the quick-assembly / disassembly module 2, such as... Figure 2As shown, firstly, adjacent wooden floorboards 1 are joined together, ensuring that the edges of adjacent wooden floorboards 1 are aligned. Secondly, the next layer of wooden floorboard 1 is placed in the middle of the previous layer of wooden floorboard 1. By controlling the rotation of the ball nut 241 and the linkage rod 24, the linkage rod 24 in the quick-release module 2 at the bottom of the wooden floorboard 1 can rotate, and during the rotation, it presses the movable plate 23, causing the movable plate 23 to move radially outward from the inside of the quick-release module 2. After the movable plate 23 moves radially, it can limit the two adjacent spliced ​​wooden floorboards 1 of the upper layer, thereby preventing the two adjacent spliced ​​wooden floorboards 1 of the upper layer from being joined together. The wooden floorboards 1 are tightly connected. Since the wooden floorboards 1 are connected via quick-release modules 2, when removal is needed, it is only necessary to release the pressure of the linkage rod 24 on the movable plate 23 within the corresponding wooden floorboard 1, and to release the linkage rods 24 within the four adjacent wooden floorboards 1 to be removed. Based on the above, in practical applications, the quick-release modules 2 at the bottom of the wooden floorboards 1 can connect adjacent wooden floorboards 1, ensuring a tight connection between adjacent wooden floorboards 1 during movement, and enabling them to withstand high-intensity exercise. Furthermore, when it is necessary to remove individual wooden floorboards 1, it is only necessary to rotate the lead screw 25, which causes the linkage rod 24 to deform. After the linkage rod 24 deforms, both ends of the linkage rod 24 will disengage from the slot 235 in the middle of the movable plate 23. At this time, the movable plate 23 can be reset, thereby realizing the independent removal of the wooden floorboard 1 that needs to be removed. Compared with the prior art, this embodiment relies on the quick-installation module 2 to achieve a tight connection between adjacent wooden floorboards 1. At the same time, relying on the quick-installation module 2, when a single wooden floorboard 1 needs to be replaced, it can be done without removing the entire wooden floorboard 1. Under the premise of this, a single wooden floor 1 is removed from the whole wooden floor 1; wherein, in this embodiment, in order to facilitate the disassembly and assembly of a single wooden floor 1, an inspection hole 13 is also opened in the center of the surface of the wooden floor 1. The size of the inspection hole 13 is slightly larger than the lead screw 25, and the size is as small as possible, and the proportion of the whole wooden floor 1 is relatively small. Based on this, it is possible to avoid opening too large a hole in the wooden floor 1, which would reduce the structural strength of the wooden floor 1. On the contrary, based on the inspection hole 13, the connection and disconnection of adjacent wooden floor 1 can be realized on the surface of the wooden floor 1, which facilitates the replacement of the wooden floor 1. It is worth noting that in the prior art, prefabricated sports wood flooring is usually numbered to ensure alignment during installation. In this embodiment, the wood floor 1 is also numbered to facilitate the determination of its position. When a single wood floor 1 needs to be replaced, the wood floor 1 with the same structure and the quick-release module 2 can be replaced based on the number. In addition, in the above embodiment, all wood floor 1 are pre-assembled with numbers. Then, the lead screw 25 is operated on the ball nut 241 to rotate the linkage rod 24 to engage with the slot 235. Based on the rotation of the linkage rod 24, the movable plate 23 is pressed, causing the movable plate 23 to move radially outward to achieve a tight connection between adjacent wood floor 1.

[0021] like Figures 1 to 3 , Figure 6 , Figure 9 and Figure 10 As shown, a liner 11 is fixed to the bottom of the wooden floor 1, and a keel 12 is fixed to the bottom of the liner 11. The liner 11 and the keel 12 are symmetrically arranged at the bottom of the wooden floor 1, and the quick-installation module 2 is arranged between the two liner 11.

[0022] To prevent the quick-release module 2 from touching the ground, in this embodiment, a liner 11 and a joist 12 are provided at the bottom of the wooden floor 1, so that the quick-release module 2 can be arranged in the middle of the wooden floor 1 with a gap between it and the ground. At the same time, in order to improve the cushioning performance of the wooden floor 1, a rubber sheet can be installed on the bottom surface of the joist 12 to meet the cushioning performance required for high-intensity sports. Meanwhile, the symmetrical arrangement of the liner 11 and the joist 12 can provide support for the wooden floor 1 and hide the quick-release module 2 at the bottom of the wooden floor 1, which is beneficial for transportation and installation, and avoids damage to the quick-release module 2 due to collision during transportation and installation.

[0023] like Figures 3 to 9 As shown, a first insert rod 231 is fixed to the outer side of the movable plate 23, and the first insert rod 231 is distributed at both ends of the outer side of the movable plate 23. When the linkage rod 24 rotates and drives the movable plate 23 to move radially, the first insert rod 231 on the movable plate 23 moves to the bottom of the adjacent wooden floor 1 and drives the keel 12 at the bottom of the two adjacent wooden floor 1 to come together.

[0024] Furthermore, in one embodiment of the present invention, the movable plate 23 rotates under the drive of the rotating linkage 24. Therefore, it is foreseeable that, without external force, the line connecting the linkage 24 and the two movable plates 23 will have an angle, such as... Figure 3As shown, when the linkage rod 24 rotates clockwise around the lead screw 25, the two ends of the linkage rod 24 will press against the movable plate 23, causing the movable plate 23 to move outward radially. After the movable plate 23 moves outward radially, the first insert rod 231 arranged on the outer side of the movable plate 23 will move outward radially simultaneously, thereby limiting the keel 12 at the bottom of the two adjacent wooden floorboards 1 on the upper layer. It can be foreseen that, in the initial stage, the wooden floorboards 1 in the up, down, left, and right directions are spliced ​​without external force, only ensuring that the edges of the adjacent wooden floorboards 1 are close together. At this time, after the movable plate 23 moves radially, the first insert rod 231 will move synchronously and contact the edge of the keel 12, so that the two adjacent wooden floorboards... Two relatively close keels 12 are centered and brought together, and pressure is applied to the keels 12 laterally, so that the two adjacent keels 12 are brought together and limited. This allows the quick-release module 2 at the bottom of the lower layer of wooden floor 1 to limit and fix the two adjacent wooden floor 1s on the upper layer. Similarly, after the linkage rod 24 in the quick-release module 2 at the bottom of the upper layer of wooden floor 1 is rotated, the keels 12 at the bottom of the two adjacent wooden floor 1s on the lower layer can also be centered and limited. Therefore, in this embodiment, the radial displacement of the movable plate 23 drives the radial displacement of the first insertion rod 231 to achieve the connection and limitation of the adjacent wooden floor 1s, ensuring that the connection between the adjacent wooden floor 1s is tight.

[0025] like Figures 3 to 9 As shown, both ends of the keel 12 are provided with connecting holes 121. A locking rod 14 is slidably connected in the connecting holes 121, and both ends of the locking rod 14 are provided with triangular blocks. A first spring 15 is also sleeved on the locking rod 14. The two ends of the first spring 15 are respectively fixed between the side wall of the keel 12 and the triangular blocks. The first spring 15 is used to drive the locking rod 14 to move radially toward the outer edge of the wooden floor 1.

[0026] As described above, the limiting of the joists 12 of the adjacent wooden floor 1 by the first insert rod 231 mainly relies on the fixed position of the movable plate 23. To prevent the movable plate 23 from not being fixed due to the linkage rod 24 not engaging with the slot 235, in this embodiment, after the first insert rod 231 and the movable plate 23 are radially displaced outward under the drive of the linkage rod 24, the first insert rod 231 will also contact the locking rod 14 and form an engaging relationship, thereby fixing the position of the first insert rod 231 and simultaneously achieving secondary fixation of the position of the movable plate 23. In other words, if the linkage rod 24 does not form an engaging relationship with the slot 235, the locking rod 14 can also complete the secondary fixation of the movable plate 23, thereby ensuring a tight connection between the adjacent wooden floor 1.

[0027] like Figures 3 to 9As shown, a second insert rod 234 is also fixed to the outer side of the movable plate 23, and the end of the second insert rod 234 is provided with an inclined surface relative to the triangular block on the locking rod 14. The first insertion rod 231 has an insertion hole 233. When the movable plate 23 is radially displaced under the pressure of the linkage rod 24, the second insertion rod 234 presses the triangular block, causing the locking rod 14 to radially displace toward the center of the wooden floor 1 and engage with the insertion hole 233 on the first insertion rod 231.

[0028] In one embodiment of the present invention, since the first insert rod 231 is used for a tight connection between adjacent left and right wooden floorboards 1, that is, based on the cooperation between the first insert rod 231 and the joist 12, the separation between adjacent left and right wooden floorboards 1 can be prevented. However, for adjacent vertical wooden floorboards 1, it may be limited to relying on the friction between the first insert rod 231 and the joist 12. Based on the above embodiment, it can be understood that by utilizing the snap-fit ​​cooperation between the first insert rod 231 and the locking rod 14, firstly, a secondary fixation of the movable plate 23 is achieved, and secondly, the connection between adjacent vertical wooden floorboards 1 can be maintained. To prevent adjacent wooden floorboards 1 from detaching, specifically, when the movable plate 23 moves radially outward, it drives the first insert rod 231 and the second insert rod 234 to move radially outward synchronously. The length of the first insert rod 231 is greater than that of the second insert rod 234. When the first insert rod 231 limits the two joists 12 and makes them move closer together, the end of the second insert rod 234 will press the triangular block at the end of the locking rod 14, causing the locking rod 14 to move toward the insertion hole 233 in the first insert rod 231. Based on the fixed position of the movable plate 23, the triangular block is continuously subjected to... The pressure applied to the end of the second insert rod 234 keeps it fixed. That is, when the movable plate 23 moves radially upward, the second insert rod 234 presses against the triangular block at the end of the locking rod 14, which, after compressing the first spring 15, causes the locking rod 14 to engage with the insertion hole 233 in the first insert rod 231. Thus, without deformation or positional change of the linkage rod 24, a tight connection is achieved between adjacent wooden floorboards 1 in the upper, lower, left, and right directions. Correspondingly, when it is necessary to remove a single wooden floorboard 1, the quick-release module in the target wooden floorboard 1 and the four wooden floorboards 1 adjacent in the upper and lower directions needs to be operated. 2. The target wooden floor 1 can be removed by deforming the linkage rod 24 in the quick-release module 2 of the four wooden floor 1 and disengaging it from the slot 235. When installing a new wooden floor 1, it is only necessary to repeat the operation of the target wooden floor 1 and the quick-release module 2 in the four wooden floor 1 to complete the replacement of the wooden floor 1. Compared with the use of hardware or clamps, this embodiment can save more time in terms of maintenance when a single wooden floor 1 needs to be replaced. Especially for competitive sports, the quick-release module 2 provided in this embodiment has more advantages.

[0029] like Figures 3 to 7 As shown, the quick-assembly module 2 also includes a limiting plate 22, which is fixedly connected to the base plate 21. The limiting plate 22 has a limiting groove 222 and a deformation groove 221 respectively provided on it relative to the movable plate 23 and the lead screw 25. A slider 232 is fixedly connected to the movable plate 23 relative to the limiting groove 222, and the slider 232 is slidably connected in the limiting groove 222. The lead screw 25 passes through the middle of the deformation groove 221.

[0030] It is worth noting that in this embodiment, the outward radial displacement of the movable plate 23 is based on the rotation of the linkage rod 24 to compress the movable plate 23 into radial displacement. When the linkage rod 24 rotates from its initial state to be perpendicular to the surfaces of the two movable plates 23, the end of the linkage rod 24 will engage in the slot 235, thereby limiting and fixing the movable plate 23. This ensures that during high-intensity movement, the linkage rod 24 remains engaged in the slot 235 on the surface of the movable plate 23 and cannot be easily removed. When any wooden floor 1 deforms and needs to be replaced, the rotation of the linkage rod 24 cannot separate it from the movable plate 23. At this time, the rotation of the lead screw 25 drives the radial displacement of the ball nut 241, causing the linkage rod 24 to deform vertically from its engaged state. It is worth noting that the engaged state of the linkage rod 24 can be understood as the linkage rod... The linkage rod 24 is perpendicular to the two movable plates 23. At this time, the radial displacement of the ball nut 241 causes the linkage rod 24 to deform. The deformation of the linkage rod 24 is mainly reflected in the middle of the linkage rod 24. The middle of the linkage rod 24 will bend and deform under the action of the ball nut 241, so that the two ends of the linkage rod 24 disengage from the slot 235, thereby canceling the engagement between the linkage rod 24 and the slot 235. The material of the linkage rod 24 is similar to that of a bow. When there is no external force in the vertical direction, it maintains its initial shape. When the ball nut 241 causes the middle of the linkage rod 24 to bend and deform upward, the two ends of the linkage rod 24 also disengage from the slot 235. After the ball nut 241 resets, the linkage rod 24 will also return to its initial shape. Therefore, based on the material of the linkage rod 24, it can be ensured that the linkage rod 24 has good performance of returning to its original shape after deformation.

[0031] like Figures 3 to 8 As shown, connecting rods 211 are fixedly connected to the top of both ends of the base plate 21, and the connecting rods 211 pass through the limiting plate 22. A baffle 212 is also fixedly connected to the base plate 21. When the linkage rod 24 rotates to be perpendicular to the movable plate 23, the baffle 212 restricts the linkage rod 24 from continuing to rotate.

[0032] To prevent the linkage rod 24 from rotating excessively, in this embodiment, a baffle 212 is installed on the base plate 21, which is equivalent to limiting the rotation angle of the linkage rod 24. When the linkage rod 24 rotates to be perpendicular to the two movable plates 23, it can no longer rotate. Correspondingly, when the linkage rod 24 deforms and disengages from the movable plate 23 under the action of the ball nut 241, the linkage rod 24 can be rotated back to its initial position. With the baffle 212 as the limit, it is convenient for the linkage rod 24 to press the movable plate 23 when the wooden floor 1 is reinstalled in the future.

[0033] like Figures 3 to 8 As shown, a straight rod 26 is connected through the side wall of the limiting plate 22, and nuts are threaded to both ends of the straight rod 26. The straight rod 26 passes through the slider 232, and a second spring 261 is also sleeved on the straight rod 26. The two ends of the second spring 261 are respectively fixed between the side wall of the limiting plate 22 and the side wall of the slider 232.

[0034] Since the linkage rod 24 disengages from the movable plate 23 after deformation, the movable plate 23 needs to be reset to its initial state. Therefore, in this embodiment, the reset of the movable plate 23 is achieved based on the second spring 261 and the straight rod 26. When the linkage rod 24 compresses the movable plate 23 radially, the slider 232 of the movable plate 23 slides in the limiting groove 222 and simultaneously compresses the second spring 261, causing the second spring 261 to compress and generate elastic potential energy. When the movable plate 23 is no longer compressed by the linkage rod 24, the movable plate 23 can be reset under the elastic force of the second spring 261.

[0035] like Figures 1 to 7 As shown, the bottom of the wooden floor 1 is provided with a fixing plate 3, and the fixing plate 3 is configured as an I-shaped plate. The top of the fixing plate 3 is snapped between the limiting plate 22 and the liner plate 11, and the bottom of the fixing plate 3 is fixedly connected to the limiting plate 22 and the liner plate 11.

[0036] like Figures 1 to 5 As shown, it also includes a maintenance tool 4. The ball nut 241 has a slotted notch at the top. The maintenance tool 4 passes through the maintenance hole 13 and engages with the slotted notch at the top of the ball nut 241 to drive the ball nut 241 and the linkage rod 24 to rotate. A maintenance cap 131 is engaged in the maintenance hole 13.

[0037] As mentioned above, when completing and canceling the tight connection between adjacent wooden floorboards 1, it is necessary to control the rotation of the linkage rod 24 and the relative rotation of the lead screw 25 and the ball nut 241. In this embodiment, when controlling the rotation of the linkage rod 24, it relies on the inspection tool 4 passing through the inspection hole 13 and engaging with the slotted notch on the surface of the ball nut 241. Rotating the inspection tool 4 drives the ball nut 241 to rotate, so that the linkage rod 24 can rotate from the initial position to be perpendicular to the two movable plates 23. When it is necessary to replace the wooden floorboard 1, the exposed inspection hole 13 is used to rotate the lead screw 25 based on the rotation of the hexagonal wrench, so that the ball nut 241 can be radially displaced on the lead screw 25, thereby realizing the deformation of the linkage rod 24, and thus the movable plate 23 is no longer squeezed and limited by the linkage rod 24.

[0038] Working principle: When installing wooden flooring 1, the quick-installation module 2 at the bottom of wooden flooring 1 can connect adjacent wooden flooring 1 units, sequentially connecting them to complete the connection of the entire wooden flooring 1. Specifically, when connecting adjacent wooden flooring 1 units based on the quick-installation module 2, as follows... Figure 2As shown, firstly, adjacent wooden floorboards 1 are joined together, ensuring that the edges of adjacent wooden floorboards 1 are aligned. Secondly, the next layer of wooden floorboard 1 is placed in the middle of the previous layer of wooden floorboard 1. By controlling the rotation of the ball nut 241 and the linkage rod 24, the linkage rod 24 in the quick-release module 2 at the bottom of the wooden floorboard 1 can rotate, and during the rotation, it presses the movable plate 23, causing the movable plate 23 to move radially outward from the inside of the quick-release module 2. After the movable plate 23 moves radially, it can limit the two adjacent spliced ​​wooden floorboards 1 of the upper layer, thereby preventing the two adjacent spliced ​​wooden floorboards 1 of the upper layer from being joined together. The wooden floorboards 1 are tightly connected. Since the wooden floorboards 1 are connected via quick-release modules 2, when removal is needed, it is only necessary to release the pressure of the linkage rod 24 on the movable plate 23 within the corresponding wooden floorboard 1, and to release the linkage rods 24 within the four adjacent wooden floorboards 1 to be removed. Based on the above, in practical applications, the quick-release modules 2 at the bottom of the wooden floorboards 1 can connect adjacent wooden floorboards 1, ensuring a tight connection between adjacent wooden floorboards 1 during movement, and enabling them to withstand high-intensity exercise. Furthermore, when it is necessary to remove individual wooden floorboards 1, it is only necessary to rotate the lead screw 25, which causes the linkage rod 24 to deform. After the linkage rod 24 deforms, both ends of the linkage rod 24 will disengage from the slot 235 in the middle of the movable plate 23. At this time, the movable plate 23 can be reset, thereby realizing the independent removal of the wooden floorboard 1 that needs to be removed. Compared with the prior art, this embodiment relies on the quick-installation module 2 to achieve a tight connection between adjacent wooden floorboards 1. At the same time, relying on the quick-installation module 2, when a single wooden floorboard 1 needs to be replaced, it can be done without removing the entire wooden floorboard 1. Under the premise of this, a single wooden floor 1 is removed from the whole wooden floor 1; wherein, in this embodiment, in order to facilitate the disassembly and assembly of a single wooden floor 1, an inspection hole 13 is also opened in the center of the surface of the wooden floor 1. The size of the inspection hole 13 is slightly larger than the lead screw 25, and the size is as small as possible, and the proportion of the whole wooden floor 1 is relatively small. Based on this, it is possible to avoid opening too large a hole in the wooden floor 1, which would reduce the structural strength of the wooden floor 1. On the contrary, based on the inspection hole 13, the connection and disconnection of adjacent wooden floor 1 can be realized on the surface of the wooden floor 1, which facilitates the replacement of the wooden floor 1. It is worth noting that in the prior art, prefabricated sports wood flooring is usually numbered to ensure alignment during installation. In this embodiment, the wood floor 1 is also numbered to facilitate the determination of its position. When a single wood floor 1 needs to be replaced, the wood floor 1 with the same structure and the quick-release module 2 can be replaced based on the number. In addition, in the above embodiment, all wood floor 1 are pre-assembled with numbers. Then, the lead screw 25 is operated on the ball nut 241 to rotate the linkage rod 24 to engage with the slot 235. Based on the rotation of the linkage rod 24, the movable plate 23 is pressed, causing the movable plate 23 to move radially outward to achieve a tight connection between adjacent wood floor 1.

[0039] In the absence of external force, the lines connecting the linkage 24 and the two movable plates 23 form an angle, such as... Figure 3As shown, when the linkage rod 24 rotates clockwise around the lead screw 25, the two ends of the linkage rod 24 will press against the movable plate 23, causing the movable plate 23 to move outward radially. When the movable plate 23 moves outward radially, the first insert rod 231 arranged on the outer side of the movable plate 23 will move outward radially simultaneously, thereby limiting the keel 12 at the bottom of the two adjacent wooden floorboards 1 on the upper layer. It can be foreseen that, in the initial stage, the wooden floorboards 1 in the up, down, left, and right directions are spliced ​​without external force, only ensuring the edge between adjacent wooden floorboards 1 and When the edges are close together, after the movable plate 23 is radially displaced, the first insert rod 231 will move synchronously and contact the edge of the keel 12, so that the two keels 12 that are relatively close to each other between the two adjacent wooden floorboards 1 are centered and close together, and pressure is applied to the keel 12 laterally, so that the two adjacent keels 12 are close together and limited, thereby realizing the limitation and fixation of the two adjacent wooden floorboards 1 on the upper layer based on the quick-release module 2 at the bottom of the lower layer wooden floorboard 1. Similarly, the connection in the quick-release module 2 at the bottom of the upper layer wooden floorboard 1 is also possible. After the movable rod 24 rotates, it can also center and limit the joists 12 at the bottom of two adjacent wooden floorboards 1 on the next layer. Therefore, in this embodiment, the radial displacement of the movable plate 23 drives the radial displacement of the first insert rod 231 to achieve the connection and limitation of adjacent wooden floorboards 1, ensuring a tight connection between adjacent wooden floorboards 1. The limitation of the joists 12 of adjacent wooden floorboards 1 by the first insert rod 231 mainly relies on the fixed position of the movable plate 23. To prevent the linkage rod 24 from failing to engage with the slot 235, which would cause the movable rod to fail to engage with the slot 235, the linkage rod 24 is used to limit the connection of adjacent wooden floorboards 1. The position of the movable plate 23 is not fixed. In this embodiment, when the first insertion rod 231 and the movable plate 23 are radially displaced outward under the drive of the linkage rod 24, the first insertion rod 231 will also contact the locking rod 14 and form a snap-fit ​​relationship, thereby fixing the position of the first insertion rod 231 and simultaneously achieving secondary fixation of the position of the movable plate 23. That is to say, even if the linkage rod 24 does not form a snap-fit ​​relationship with the slot 235, the locking rod 14 can still complete the secondary fixation of the movable plate 23, thereby ensuring a tight connection between adjacent wooden floorboards 1.

[0040] Since the first insert rod 231 is used to tightly connect the left and right adjacent wooden floorboards 1, that is, based on the cooperation between the first insert rod 231 and the joist 12, it can prevent the left and right adjacent wooden floorboards 1 from separating. However, for the vertically adjacent wooden floorboards 1, it may only rely on the friction between the first insert rod 231 and the joist 12 to achieve this. Based on the above embodiment, it can be understood that by using the snap-fit ​​cooperation between the first insert rod 231 and the locking rod 14, firstly, a secondary fixation of the movable plate 23 can be achieved, and secondly, the vertically adjacent wooden floorboards 1 can be fixed to prevent vertically adjacent wooden floorboards 1 from separating. The wooden floor 1 detaches. Specifically, when the movable plate 23 moves outward radially, the movable plate 23 drives the first insert rod 231 and the second insert rod 234 to move outward radially synchronously. The length of the first insert rod 231 is greater than that of the second insert rod 234. When the first insert rod 231 limits the two joists 12 and makes the two joists 12 relatively close, the end of the second insert rod 234 will press the triangular block at the end of the locking rod 14, causing the locking rod 14 to move toward the insertion hole 233 in the first insert rod 231. Based on the premise that the position of the movable plate 23 is fixed, the triangular block is continuously subjected to the second insert rod 234. The pressure applied to the end of 34 keeps it fixed. That is, when the movable plate 23 moves radially upward, the second insert rod 234 presses the triangular block at the end of the locking rod 14, which, after compressing the first spring 15, causes the locking rod 14 to engage with the insertion hole 233 in the first insert rod 231. Thus, without deformation or positional change of the linkage rod 24, a tight connection is achieved between adjacent wooden floorboards 1 in the upper, lower, left, and right directions. Correspondingly, when it is necessary to remove a single wooden floorboard 1, the quick-release module 2 in the target wooden floorboard 1 and the four wooden floorboards 1 adjacent in the upper and lower directions is operated to make... The linkage rod 24 in the quick-release module 2 within the four wooden floorboards 1 deforms and disengages from the slot 235, thus enabling the removal of the target wooden floorboard 1. When installing a new wooden floorboard 1, it is only necessary to repeat the operation of the target wooden floorboard 1 and the quick-release module 2 within the four wooden floorboards 1 to complete the replacement of the wooden floorboard 1. Compared with the use of hardware connections or clamp connections, this embodiment can save more time in terms of maintenance time when a single wooden floorboard 1 needs to be replaced. Especially for competitive sports, the quick-release module 2 provided in this embodiment has a greater advantage.When the linkage rod 24 rotates from its initial state to be perpendicular to the surfaces of the two movable plates 23, the end of the linkage rod 24 will engage in the slot 235, thereby limiting and fixing the movable plates 23. This ensures that during high-intensity movement, the linkage rod 24 remains engaged in the slot 235 on the surface of the movable plates 23 and cannot be easily removed. When any wooden floorboard 1 deforms and needs to be replaced, the rotation of the linkage rod 24 alone cannot separate it from the movable plates 23. At this time, the rotation of the lead screw 25 drives the radial displacement of the ball bearing nut 241, causing the linkage rod 24 to deform vertically from its engaged state. It is worth noting that the engaged state of the linkage rod 24 can be understood as the linkage rod 24 maintaining a perpendicular relationship with the two movable plates 23. At this time, based on the ball bearing... The radial displacement of nut 241 causes deformation of linkage rod 24. This deformation primarily occurs in the middle section of linkage rod 24. Under the influence of ball nut 241, the middle section of linkage rod 24 bends and deforms, causing both ends of linkage rod 24 to disengage from slot 235, thus canceling the engagement between linkage rod 24 and slot 235. Linkage rod 24 is made of a material similar to a bow, maintaining its initial shape in the absence of external force in the vertical direction. When ball nut 241 causes the middle section of linkage rod 24 to bend upwards, both ends of linkage rod 24 also disengage from slot 235. After ball nut 241 returns to its original position, linkage rod 24 also returns to its initial shape. Therefore, based on the material of linkage rod 24, good post-deformation recovery performance can be ensured.
