Description

Technical Field

[0001] This utility model relates to the field of assembled sports flooring technology, specifically to a telescopic component and connector for assembling sports flooring. Background Technology

[0002] Modular flooring, also known as modular sports flooring, can be laid directly on cement or asphalt base surfaces without the need for adhesives. Each floorboard is connected by a unique interlocking system, making installation very simple and allowing for easy disassembly.

[0003] Existing interlocking flooring mostly uses fixed clips or pins for connection during assembly. However, when the temperature changes, the interlocking flooring will be affected by thermal expansion and contraction. The fixed mechanism does not have the ability to compensate for gaps during use, which can easily cause the connection to break and make it inconvenient to use. Therefore, an expansion joint and connector for interlocking sports flooring is proposed to solve the above problems. Utility Model Content

The four insertion rods are respectively inserted into the interior of four insertion holes, and multiple trapezoidal annular grooves are opened on the outer side of each of the four insertion rods.

[0010] The beneficial effects of this utility model are: by inserting the connecting mechanism into the telescopic mechanism to fix the connecting shaft of multiple floorboards, when the floorboards expand and contract with heat, the spring in the telescopic mechanism compensates for the gaps caused by thermal expansion and contraction. At the same time, the connecting mechanism can also maintain the connection of the floorboards.

An installation plate located between the two floorboards is fixedly connected to the bottom of the connecting plate. Rubber pads are fixedly connected to both the left and right sides of the installation plate.

[0020] The advantage of adopting the above-mentioned further solution is that the rubber pad can provide impact protection when the floor slips.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the embodiments, by Figure 1-4 The present invention provides a telescopic component and connector for assembling sports flooring. The present invention includes a floor 1, the top of which has four positioning grooves 2, and the interior of the floor 1 is provided with symmetrically distributed telescopic mechanisms 3. The same connecting mechanism 4 is inserted between four adjacent floor 1s, and the connecting mechanism 4 is engaged with the telescopic mechanisms 3 of the four floor 1s respectively.

[0030] The telescopic mechanism 3 includes a slider 301. One end of the slider 301 near the inner side of the floor 1 is fixedly connected to a spring 302 that is fixedly connected to the inside of the floor 1. The slider 301 has an insertion hole 303 that is adapted to the connecting mechanism 4. A rubber ring 304 is embedded in the inner side of the insertion hole 303.

[0031] The connecting mechanism 4 includes a sealing ring 401, a fixing plate 402 is fixedly connected to the bottom of the sealing ring 401, and four insertion rods 403 are fixedly connected to the bottom of the fixing plate 402. The four insertion rods 403 are respectively inserted into the interior of four insertion holes 303, and multiple trapezoidal annular grooves 404 are opened on the outer side of each of the four insertion rods 403.

[0032] The floor 1 includes a lower plate 101 and an upper plate 102. The lower plate 101 is fixedly connected to the bottom of the upper plate 102. The lower plate 101 has four mounting slots 103 inside, which are adapted to the four telescopic mechanisms 3 respectively.

[0033] The pre-installed mounting slot 103 facilitates subsequent equipment installation.

[0034] The upper plate 102 and the sealing ring 401 are both made of hard rubber, while the lower plate 101 and the fixing plate 402 are both made of hard plastic.

[0035] Hard rubber plates not only meet the needs of sports but also have strong wear resistance, which helps to extend their service life.

[0036] The fixing plate 402 and the sealing ring 401 have the same embedding hole 5 inside. The embedding hole 5 has a handle 6 that is fixedly connected to the inside of the fixing plate 402. The fixing plate 402 and the sealing ring 401 have the same flat plug 7 located outside the handle 6 inside. The flat plug 7 is a hard rubber plug.

[0037] The pre-installed handle 6 facilitates the removal of the floor 1.

[0038] The bottom of the fixed plate 402 is fixedly connected to an anti-collision mechanism 8. The anti-collision mechanism 8 includes a connecting plate 801, which is fixedly connected to the bottom of the fixed plate 402. The bottom of the connecting plate 801 is fixedly connected to an installation plate 802 located between the two floorboards 1. Rubber pads 803 are fixedly connected to both the left and right sides of the installation plate 802.

[0039] Rubber pad 803 provides impact protection when floor 1 slips.

[0040] The fixing plate 402 and the flat plug 7 are provided with slots 9 on both the left and right sides. The tops of the floor 1 and the sealing ring 401 are rounded. The insert rod 303 is internally connected with a ball bearing 10 that is slidably connected to the bottom wall of the inner cavity of the floor 1.

[0041] The ball bearing 10 can convert sliding friction into rolling friction, thus improving service life.

[0042] Working principle:

[0043] Step 1: Arrange multiple floorboards 1 in a rectangular array, and then insert the plug rod 403 of the connecting mechanism 4 into the insertion hole 303 of the telescopic mechanism 3. The rubber ring 304 in the insertion hole 303 deforms and is inserted into the trapezoidal annular groove 404 to fix the plug rod 403.

[0044] Step 2: When the floor 1 expands and contracts due to heat, resulting in a change in the gap, the elastic deformation of the spring 302 compensates for the displacement of the floor 1. During the compensation process, the slider 301 slides in the mounting groove 103, while the insert rod 403 remains relatively fixed. The sliding friction between the insert rod 403 and the mounting groove 103 is converted into rolling friction by the ball 10, reducing its sliding friction.

[0045] Step 3: When it is necessary to remove the floor 1, insert an external pliers tool into the slot 9 between the flat plug 7 and the sealing ring 401 to pull out the flat plug 7. Then, insert the pliers tool into the slot 9 of the fixing plate 402 and use the auxiliary handle 6 to pull out the connecting mechanism 4.
