Description

Technical Field

[0001] The utility model relates to the field of sports wooden floor installation, in particular to a sports wooden floor frame positioning structure. Background Art

[0002] Sports wood flooring offers excellent load-bearing capacity, high shock absorption, and deformation resistance. Its excellent impact absorption properties can effectively protect athletes from sports injuries. Sports wood flooring typically consists of a keel laid on the ground, a subfloor layer laid on the keel, and a decking layer laid on the subfloor.

[0003] The keels are typically arranged in two layers, staggered in a cross pattern. The keels are typically laid by first laying a moisture-proof membrane on the ground, then laying the lower keel layer. The upper keel layer is then laid on top of the lower keel layer. Rubber mats are placed between the upper and lower keels as the upper keels are laid. Strong nails are then used to secure the upper and lower keels together.

[0004] When using the existing keel laying method, when laying the upper keel, because the keel is usually composed of several rectangular wooden planks, moving one end of the wooden plank easily causes the other end of the wooden plank to move, and the lower keel is not fixedly connected to the ground, so the lower keel and the laid upper keel are pulled by the wooden planks being laid and displaced, so that the keel needs to be adjusted back to the set position many times during the process of laying the keel on the ground, which reduces the keel laying efficiency. Therefore, there is still room for improvement. Summary of the Invention

[0005] In order to improve the stability of the keel of the sports wooden floor during the laying process, the present application provides a sports wooden floor frame positioning structure.

[0006] The present application provides a sports wooden floor frame positioning structure adopting the following technical solutions:

[0007] A sports wooden floor frame positioning structure includes a fixing seat installed on the wooden square of the lower keel and a fixing rod used to connect the fixing seats fixed on the wooden squares of the lower keel that are on different straight lines and adjacent to each other. The fixing seat is provided with a connecting piece for installing the fixing rod to the fixing seat. The fixing seat is detachably connected to the wooden square of the lower keel, and the fixing rod is detachably connected to the fixing seat.

[0008] By adopting the above technical solution, fixing bases are first installed on the wooden planks of the lower keel, and then fixing rods are installed on the fixing bases via connectors. The structure is simple. The distance between two points in a straight line is determined, and the wooden planks of the lower keel are fixed by two or more fixing bases. This ensures that adjacent wooden planks on different straight lines of the lower keel are spaced apart, reducing the need to drill holes into the ground. The fixing bases are then fixed to the ground using screws to secure the wooden planks of the lower keel. This reduces the risk of damage to the ground caused by drilling holes and damage to the moisture-proof film laid on the ground, which helps to improve the stability of the lower keel, thereby improving the stability of the keel of the sports wood floor during installation and improving the efficiency of laying the keel on the ground. By arranging the fixing seat to be detachably connected to the wooden plank of the lower keel and the fixing rod to be detachably connected to the fixing seat, the fixing seat and the fixing rod can be removed from the wooden plank of the lower keel after the keel is laid on the ground, so that the fixing seat and the fixing rod can be reused, reducing the fixed connection between the fixing seat and the wooden plank of the lower keel and the fixed connection between the fixing seat and the fixing rod, which results in the fixing seat and the fixing rod being disposable items and causing the cost of making the keel to increase, which is conducive to the reuse of resources for making the keel, thereby reducing resource waste.

[0009] Preferably, the fixing rod is in the shape of a rectangular rod, and the connecting piece is a fixing groove fixed on both sides of the fixing seat along the width direction. The fixing groove is in the shape of a U-shaped groove, and the notch of the fixing groove faces the side away from the ground. One end of the fixing groove along the length direction is fixed to the side wall of the fixing seat, and the spacing between the two side walls of the fixing groove is consistent with the width of the rectangular rod. The fixing groove is also provided with a limiting piece that limits the fixing rod from sliding out of the fixing groove in the direction away from the fixing seat.

[0010] By adopting the above technical solution, the fixing seats fixed on the adjacent wooden squares on different lines of the lower keel are adjusted until the fixing grooves of the adjacent fixing seats fixed on the lower keel are aligned, and then the ends of the fixing rod are respectively inserted into the aligned fixing grooves along the length direction, so that the ends of the fixing rod can be fixedly connected to the fixing seats fixed on the adjacent wooden squares on different lines of the lower keel, which is simple to operate. By sliding the fixing rod on the limiting member out of the fixing groove in a direction away from the fixing seat, the fixing rod restricts the relative movement of the adjacent wooden squares on different lines of the lower keel, reducing the need to tighten the fixing screws multiple times when fixing the fixing rod and the connecting member with fastening screws during the installation of the keel on the ground, thereby improving the efficiency of the installation of the keel on the ground. At the same time, by setting the notch of the fixing groove to the side away from the ground, the fixing rod is not easily shaken out of the fixing groove under the action of gravity when subjected to vibration during the installation of the keel on the ground, thereby reducing the situation in which the fixing rod is shaken out of the fixing groove due to vibration during the installation of the keel on the ground, thereby improving the stability of the keel. By arranging the connecting piece as a fixing groove, the structure is simple and the cost of manufacturing the fixing seat is reduced.

[0011] Preferably, the limiting member is a protrusion fixed on the side wall of the fixing rod along the width direction, and the side wall of the fixing groove along the width direction is further recessed with a sliding groove for the protrusion to slide into the fixing groove from the notch of the fixing groove.

[0012] By adopting the above technical solution, by fixing a protrusion on the fixing rod and providing a slide groove in the fixing groove, the protrusion is unlikely to hinder the fixing rod from being inserted into the fixing groove. At the same time, the interlocking engagement between the protrusion and the side wall of the slide groove prevents the fixing rod from sliding out of the fixing groove away from the fixing seat, resulting in a simple structure. Inserting the fixing rod into the fixing groove simultaneously drives the protrusion into the slide groove, reducing the work of separately operating the limiting member and facilitating efficient installation of the fixing rod into the fixing groove. When the fixing rod needs to be removed from the fixing groove, it can be simply pulled out of the fixing groove. This simple operation facilitates efficient removal of the fixing rod from the fixing groove, thereby further improving the efficiency of installing the keel into the ground.

[0013] Preferably, the fixing seat is in the shape of a U-shaped groove, the spacing between the two side walls of the fixing seat is not less than the width of the wooden square of the lower keel, and the fixing seat is provided with a switching member for switching the fixing seat and the wooden square of the lower keel between the fixed connection state and the disconnection state.

[0014] By adopting the above technical solution, the fixing seat is configured as a U-shaped groove, which makes the structure of the fixing seat simple and greatly reduces the cost of manufacturing the fixing seat. When the fixing seat needs to be installed on the wooden planks of the lower keel, the fixing seat is placed on the wooden planks of the lower keel. When the fixing seat needs to be removed from the wooden planks of the lower keel, it is simply removed from the wooden planks of the lower keel. The operation is simple and the efficiency of installing and removing the fixing seat from the lower keel is further improved. By setting the spacing between the two side walls of the fixing seat to be no less than the width of the wooden planks of the lower keel and the switching member, the situation where the width of the fixing seat is less than the width of the wooden planks of the lower keel, resulting in the fixing seat being unable to be installed on the wooden planks of the lower keel, is reduced. At the same time, the situation where the fixing seat is slidably connected to the wooden planks of the lower keel, resulting in the fixing seat being easily slid relative to the wooden planks of the lower keel after being subjected to vibration, is reduced, which is conducive to improving the stability of the fixing seat. By setting the fixing seat as a U-shaped groove and the switching member, the fixing seat can be installed at any position along the length direction of the wooden planks of the lower keel, which is conducive to improving the adjustment efficiency of the fixing seat.

[0015] Preferably, the switching member is a screw, and a base threaded hole for the screw to be screwed into is provided on the side wall of the fixing seat.

[0016] By adopting the above technical solution, a base threaded hole is provided on the fixing base, and the switching member is provided as a screw, which simplifies the structure and reduces the cost of the switching member, thereby reducing the cost of manufacturing the sports wood floor frame positioning structure. When the switching member is needed to fix the fixing base to the wooden planks of the lower keel, the screw can be screwed into the groove of the fixing base through the base threaded hole until the screw abuts against the wooden planks of the lower keel. When the fixing base needs to be removed from the wooden planks of the lower keel, the screw can be screwed out of the groove of the fixing base through the base threaded hole, and then the fixing base can be removed, further improving the efficiency of removing and installing the fixing base from the wooden planks of the lower keel.

[0017] Preferably, the fixing seat is fixed with a limiting frame, and the limiting frame is provided with a limiting threaded hole for screwing in a screw, and the limiting threaded hole is directly opposite to the threaded hole of the base.

[0018] By adopting the above technical solution, the fixing base is formed into a U-shaped groove, and the side walls of the fixing base are thin. When the screw is screwed out of the base threaded hole, it is easy to over-rotate and completely screw out of the base threaded hole, causing the screw to fall out and easily be lost. By providing a limiting frame and a limiting threaded hole, when the screw is completely screwed out of the base threaded hole, the limiting frame and the limiting threaded hole connect the screw and the fixing base, reducing the risk of the screw being lost when completely screwed out of the base threaded hole, thereby reducing the waste caused by lost screws.

[0019] Preferably, the fixing frame is provided with a positioning piece for fixing the wooden planks of the upper keel and the wooden planks of the lower keel.

[0020] By adopting the above technical solution, in the process of laying the upper keel on the lower keel, it is necessary to first complete the laying of the upper keel, and then use strong nails to fix the connection between the lower and upper keels. During the laying of the upper keel, vibrations are likely to occur, causing the upper keel to shift easily. By arranging fixings on the fixing seat, the upper keel and the lower keel are temporarily fixed, which reduces the displacement of the upper keel that has been laid due to vibration or impact during the laying of the upper keel, resulting in the need to readjust the position of the upper keel multiple times later. At the same time, it also reduces the displacement of the upper keel due to vibration when the strong nail is hammered into the connection between the upper and lower keels, resulting in the displacement of the upper keel relative to the expected position after the upper and lower keels are fixed, which is conducive to improving the accuracy of the installation of the upper keel to the lower keel.

[0021] Preferably, the positioning member is a positioning plate fixed to a side of the fixing seat away from the notch.

[0022] By adopting the above technical solution, two fixing bases are installed on both sides of the width direction of the wooden planks of the upper keel, so that the two positioning plates abut against the two sides of the wooden planks of the upper keel in the width direction. The fixing bases are fixed to the wooden planks of the lower keel by screwing screws into the threaded holes of the bases, thereby fixing the upper and lower keels. The operation is simple. By simply adjusting the position of the fixing bases, the upper and lower keels can be fixed by using the fixing bases to fix adjacent wooden planks on different straight lines of the lower keel. At the same time, the fixing members are set as positioning plates, which has a simple structure and helps reduce the cost of manufacturing the positioning structure of the sports wood floor frame.

[0023] Preferably, the fixing seat is provided with a connecting rod connecting the fixing seats fixed on the same wooden square, the connecting rod is in the shape of a rectangular rod, and the fixing seat is also provided with an ear hook for inserting the connecting rod, the ear hook is in the shape of a U-shaped groove, and the side wall of the ear hook along the width direction is fixed to the side wall of the fixing seat, the notch of the ear hook faces the side away from the ground, and the ear hook is provided with a limiting part that limits the connecting rod from sliding out of the ear hook along the length direction of the ear hook, and the spacing between the two side walls of the U-shaped groove is consistent with the width of the connecting rod.

[0024] By adopting the above technical solution, the lower keel is composed of several wooden planks. When the lower keel is subjected to vibration, adjacent wooden planks on the same straight line of the lower keel are prone to relative displacement at the connection point. By providing ear hooks and connecting rods, two fixing seats are respectively installed on adjacent wooden planks of the same length of the lower keel, and the ends of the connecting rod are respectively inserted into the ear hooks of the two fixing seats used to fix adjacent wooden planks of the same length of the lower keel. This ensures that adjacent wooden planks on the same straight line of the lower keel are fixedly connected, reducing the relative displacement of adjacent wooden planks on the same straight line of the lower keel due to vibration, which would result in the need for multiple keel adjustments during keel laying, and is conducive to improving the efficiency of laying the keel on the ground.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By providing a fixing seat and a fixing rod, the spacing between adjacent wooden planks on different straight lines of the lower keel is maintained, reducing the need to drill holes into the ground. The fixing seat is then fixed to the ground with screws to fix the wooden planks of the lower keel, thereby reducing the damage to the ground caused by drilling holes into the ground and the damage to the moisture-proof film laid on the ground. This is beneficial to improving the stability of the lower keel, thereby improving the stability of the keel of the sports wood floor during the laying process, and at the same time improving the efficiency of laying the keel on the ground. By providing a fixing seat that is detachably connected to the wooden planks of the lower keel and a fixing rod that is detachably connected to the fixing seat, the fixing seat and the fixing rod can be removed from the wooden planks of the lower keel after the keel is laid on the ground, thereby making the fixing seat and the fixing rod reusable, reducing the need for the fixing seat to be fixed to the wooden planks of the lower keel and the fixing seat to be fixed to the fixing rod, resulting in the fixing seat and the fixing rod being disposable items, which increases the cost of making the keel. This is beneficial to the reuse of resources used in making the keel, thereby reducing resource waste.

[0027] 2. By setting the spacing between the two side walls of the fixing seat to be no less than the width of the wooden planks of the lower keel, screws and positioning plates, the fixing seat can be mounted on any position of the wooden planks of the lower keel along the length direction. At the same time, the screws can fix the fixing seat to any position of the wooden planks of the lower keel along the length direction, and the positioning plate fixes the wooden planks of the upper keel to the wooden planks fixed to the lower keel.

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The embodiment of the present application discloses a sports wooden floor frame positioning structure, referring to Figure 1 as well as Figure 2 The structure comprises a fixing base 11 mounted on the wooden planks of the lower keel 61, and a fixing rod 12 for connecting fixing bases 11 fixed to adjacent wooden planks on different lines of the lower keel 61. In this embodiment, the fixing base 11 is a U-shaped groove, and the spacing between the two side walls of the fixing base 11 matches the width of the wooden planks of the lower keel 61.

The length of the sliding groove 21 is consistent with the length of the protrusion 121, and the depth of the sliding groove 21 is consistent with the depth of the fixing groove 2.

[0037] Reference Figure 3 The fixing base 11 is movably connected to a switching member for switching the fixing base 11 between a fixed connection state and a disconnection state with the wooden planks of the lower keel 61. In this embodiment, the switching member is a screw 4 threadedly connected to the fixing base 11. The side walls on both sides of the fixing base 11 are threadedly connected to the screw 4. The side walls on both sides of the fixing base 11 are each provided with a base threaded hole (not shown in the figure) for the screw 4 to be screwed into the groove of the fixing base 11.

[0038] Reference Figure 3 A limiting frame 51 is also fixed to the fixing base 11. In this embodiment, there are two limiting frames 51, and the two limiting frames 51 are fixed to the side walls of the fixing base 11 along the width direction. The limiting frames 51 are U-shaped grooves, and the side of the limiting frames 51 away from the bottom wall is fixedly connected to the side wall of the fixing base 11. The bottom wall of the limiting frame 51 is provided with a limiting threaded hole for screwing the screw 4 into the groove of the fixing base 11. The two limiting threaded holes are respectively opposite the two threaded holes in the base.

[0039] Reference Figure 1 The fixing base 11 is movably connected to a connecting rod 13 that connects the fixing base 11 to the same wooden block. An ear hook 3 is fixed to the side wall of the fixing base 11, into which the connecting rod 13 is inserted. In this embodiment, the ear hook 3 is in the form of a U-shaped groove. Two ear hooks 3 are fixed to the side wall of the fixing base 11, one located on each side wall of the fixing base 11. The spacing between the side walls of the ear hook 3 is the same as the width of the connecting rod 13. The connecting rod 13 is in the form of a rectangular rod. The ear hook 3 is provided with a restricting member that limits the connecting rod 13 from sliding out of the ear hook 3 along its length. In this embodiment, the restricting member is a clamping block 131 fixed to the side wall of the ear hook 3 along its width. The side walls of the ear hook 3 also have recessed notches 31 for the clamping block 131 to slide into the ear hook 3 from the notch. The depth of the notch 31 is the same as the depth of the groove of the ear hook 3, and the length of the notch 31 is the same as the length of the clamping block 131.

[0040] Reference Figure 3 The fixing seat 11 is also fixed with a positioning piece for fixing the wooden squares of the upper keel 62 and the wooden squares of the lower keel 61. In this embodiment, the positioning piece is a positioning plate 111 fixed on the side of the fixing seat 11 away from the groove of the fixing seat 11. The positioning plate 111 is in the shape of a rectangular plate, and the two ends of the positioning plate 111 along the length direction are flush with the two sides of the fixing seat 11 along the width direction.

[0041] The implementation principle of the sports wooden floor frame positioning structure in the embodiment of the present application is as follows:

[0042] When it is necessary to use the sports wooden floor frame positioning structure to fix the keel, first unscrew the screws 4 on both sides of the fixing seat 11 from the groove of the fixing seat 11, and then put the fixing seat 11 on the wooden square of the lower keel 61, and the notch of the fixing groove 2 and the notch of the ear hook 3 are both facing the side away from the ground, and the two positioning plates 111 are respectively abutted against the two sides of the wooden square of the upper keel 62 along the width direction along the side away from the fixing seat 11 in the thickness direction. Then, insert the two ends of the fixing rod 12 into the fixing slots 2 of adjacent fixing bases 11 fixed on different lines of the lower keel 61. The protrusions 121 are inserted from the guide slots 21 into the fixing slots 2. The interlocking engagement between the protrusions 121 and the sidewalls of the guide slots 21 prevents the fixing rod 12 from sliding out of the fixing slots 2 away from the fixing base 11. Then, insert the two ends of the connecting rod 13 into the ear hooks 3 of adjacent fixing bases 11 fixed on the same line of the lower keel 61. The locking blocks 131 engage the notches 31, preventing the connecting rod 13 from sliding out of the ear hook 3 along the length of the ear hook 3. Then, screw the screws 4 on either side of the fixing base 11 along the width direction into the grooves of the fixing base 11 until the screws 4 on either side of the fixing base 11 along the width direction respectively abut against the two sides of the wooden square of the lower keel 61 along the width direction.

[0043] After the upper keel 62 and the lower keel 61 are fixed with strong nails, when the sports wooden floor frame positioning structure needs to be removed from the keel, first remove the connecting rod 13 from the ear hook 3, then remove the fixing rod 12 from the fixing groove 2, and then unscrew the screws 4 on both sides of the fixing seat 11 along the width direction out of the groove of the fixing seat 11, and then remove the fixing seat 11 from the keel.

[0044] By providing the fixing seat 11, the fixing groove 2, the fixing rod 12, the sliding groove 21, the protrusion 121, the notch 31 and the blocking block 131, the fixing seat 11 and the fixing rod 12 can fix the wooden planks of the lower keel 61 while reducing the situation where the fixing rod 12 is easily disengaged from the fixing groove 2 due to vibration.

[0045] By setting the spacing between the two side walls of the fixing seat 11 to be no less than the width of the wooden planks of the lower keel 61, the screws 4 and the positioning plate 111, the fixing seat 11 can be mounted on any position of the wooden planks of the lower keel 61 along the length direction. At the same time, the screws 4 can fix the fixing seat 11 to any position of the wooden planks of the lower keel 61 along the length direction. At the same time, the positioning plate 111 fixes the wooden planks of the upper keel 62 to the wooden planks fixed to the lower keel 61.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
