Description

Technical Field

[0001] This utility model relates to the field of flooring, and in particular to an SPC flooring connection structure. Background Technology

[0002] Flooring is the surface structure of a house's ground or floor, mostly made of materials such as wood. Based on structure, it can be divided into solid wood flooring, engineered wood flooring, and three-layer engineered wood flooring, among others. SPC flooring is an environmentally friendly composite flooring made primarily of stone powder and polyvinyl chloride (PVC). It features wear resistance, water resistance, and high stability. Traditionally, SPC flooring is connected in pairs using a direct snap-fit ​​method, which cannot quickly self-lock the joined SPC flooring. This directly leads to an unstable connection structure, making it easy for the two sets of SPC flooring to loosen, thus directly affecting the overall installation stability of the SPC flooring. Furthermore, when disassembling damaged SPC flooring, the entire SPC flooring needs to be removed to replace a single piece, which is very troublesome.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes an SPC floor connection structure, which solves the aforementioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: An SPC flooring connection structure includes two sets of connecting plates symmetrically arranged vertically. An SPC flooring body is snapped between the two sets of connecting plates. The top and bottom sides of each SPC flooring body have strip grooves for the connecting plates to snap into place. An auxiliary connecting component is provided between the two sets of connecting plates. The auxiliary component includes vertical grooves on the front and back sides of each SPC flooring body. Vertical shafts are rotatably mounted on the front and back sides of the upper connecting plate. A snap-fit ​​side plate is fixed at the bottom. The two adjacent sets of vertical grooves are adapted to the vertical shaft and snap-fit ​​side plates. The front and back of the top of the lower connecting plate are provided with arc-shaped grooves that cooperate with the snap-fit ​​side plates. The front and back of the top of the upper connecting plate are provided with circular grooves that cooperate with the vertical shaft. A reinforcing frame is fixed at the top of the vertical shaft and is located in the circular groove. An anti-slip side frame is slidably installed in the reinforcing frame. A spring is fixed between the anti-slip side frame and the side wall of the reinforcing frame. Two sets of limiting grooves for inserting the anti-slip side frame are provided in each set of circular grooves.

[0006] The SPC floor connection structure described above is further characterized by the following: both sides of the connecting plates that are close to each other are fixed with a card plate, and each set of strip grooves is provided with a card slot and the card plate is engaged in the inner card slot.

[0007] The SPC floor connection structure described above is further characterized by the following: each set of circular grooves is fitted with a sealing sleeve, and the sealing sleeve has an auxiliary groove for use with the reinforcing frame and the anti-slip side frame.

[0008] The SPC floor connection structure described above is further characterized by the following: each set of reinforcing frames has a transverse groove on its front and back sides, and the protruding ends of the anti-slip side frame on its front and back sides are inserted into the transverse groove.

[0009] The present invention provides an SPC floor connection structure as described above, further comprising: the top of the connecting plate, the top of the SPC floor body, and the top of the sealing sleeve are all on the same horizontal plane.

[0010] The SPC floor connection structure described above is further characterized by the following: each set of vertical shafts is provided with an auxiliary bearing at its top end, and the outer ring of the auxiliary bearing is embedded in the upper connecting plate.

[0011] The SPC floor connection structure described above is further characterized in that the included angle between the two sets of limiting grooves in each set of circular grooves is 90 degrees.

[0012] In summary, the beneficial effects of this utility model are as follows: This invention, by setting auxiliary connecting components, can form a quick-locking structure for two adjacent sets of SPC floor bodies, and the connection method is a snap-fit ​​self-locking. While ensuring the connection stability of the two sets of SPC floor bodies, it improves the connection efficiency of the two sets of SPC floor bodies. Moreover, if it is necessary to replace a damaged set of SPC floor bodies, only the connecting plates on both sides need to be removed to replace that set of SPC floor bodies, without having to disassemble the entire SPC floor body to replace the damaged one. This improves the replacement effect and efficiency of SPC floor bodies, and further enhances the overall functionality of the connection structure.

[0013] This invention improves the stability of two sets of SPC flooring bodies when they are joined by setting a card plate and a card slot, and by using the interlocking of the two, it avoids the two sets of SPC flooring bodies from easily separating when they are joined.

[0014] This invention uses a sealing sleeve and an auxiliary groove to seal the circular groove, which improves the aesthetics and prevents impurities from entering the groove and affecting the normal and stable operation of its internal structure.

[0015] This invention improves the stability of the anti-slip side frame during movement by setting a transverse groove to limit its sliding movement, thus preventing deviation or tilting.

[0016] This invention improves the flatness of the SPC flooring body during jointing by designing it to be on the same horizontal plane. This not only enhances the overall aesthetics of the SPC flooring body but also prevents protrusions from tripping over users, thus improving safety.

[0017] This invention uses an auxiliary bearing to ensure stable rotation of the vertical shaft, preventing obstruction and positioning the shaft so that it can only rotate and not move up or down.

[0018] This invention sets a 90-degree angle to ensure that the snap-fit ​​side plate can stably enter the vertical groove in the initial state without obstruction, and to ensure that the subsequent anti-slip side frame can be stably inserted into the right limit groove, thereby improving docking efficiency.

[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0023] An SPC flooring connection structure includes two sets of connecting plates symmetrically arranged vertically. SPC flooring bodies 3 are snapped together between the two sets of connecting plates 1. The top and bottom sides of each SPC flooring body 3 have slots 4 for the connecting plates 1 to snap onto each other. An auxiliary connection assembly is provided between the two sets of connecting plates 1. The auxiliary connection assembly includes vertical slots 6 on the front and back sides of each SPC flooring body 3. Vertical shafts 7 are rotatably mounted on the front and back sides of the upper connecting plate 1. A snap-fit ​​side plate 8 is fixed to the bottom end of each vertical shaft 7. Adjacent sets of vertical slots... 6 is adapted to the vertical shaft 7 and the snap-fit ​​side plate 8. The front and back of the top of the lower connecting plate 1 are provided with arc-shaped grooves 9 that cooperate with the snap-fit ​​side plate 8. The front and back of the top of the upper connecting plate 1 are provided with circular grooves 10 that cooperate with the vertical shaft 7. The top of the vertical shaft 7 is fixed with a reinforcing frame 12 located in the circular groove 10. An anti-slip side frame 13 is slidably arranged in the reinforcing frame 12. A spring 14 is fixed between the anti-slip side frame 13 and the side wall of the reinforcing frame 12. Each set of circular grooves 10 is provided with two sets of limiting grooves 15 for the anti-slip side frame 13 to be inserted.

[0024] Specifically, this utility model, through the design of auxiliary components, including the vertical shaft 7, the snap-fit ​​side plate 8, and the arc-shaped groove 9, can initially position the two sets of connecting plates 1, thereby initially positioning the two sets of SPC floor bodies 3. Furthermore, the design of the reinforcing frame 12, the anti-slip side frame 13, the spring 14, and the limiting groove 15 forms a locking structure for the vertical shaft 7 and the snap-fit ​​side plate 8, thus positioning the rotated snap-fit ​​side plate 8 and ensuring its stable engagement with the arc-shaped groove 9. This forms a quick-locking structure for the two adjacent sets of SPC floor bodies 3, and the connection... The method is a snap-fit ​​self-locking connection, which improves the connection efficiency of the two sets of SPC floor bodies 3 while ensuring the connection stability of the two sets of SPC floor bodies 3. If it is necessary to replace a damaged set of SPC floor bodies 3, only the connecting plates 1 on both sides need to be removed to replace the damaged set of SPC floor bodies 3. There is no need to disassemble the entire SPC floor body 3 to replace the damaged SPC floor body 3, which improves the replacement effect and efficiency of SPC floor body 3 and further enhances the overall functionality of the connection structure.

[0025] Both sides of the connecting plate 1 that are close to each other are fixed with a card plate 2. Each set of strip grooves 4 has a slot 5 and the card plate 2 is engaged in the inner slot 5.

[0026] Specifically, the interlocking of the card plate 2 and the card slot 5 is used to further improve the stability of the two sets of SPC floor bodies 3 when they are connected, and to prevent the two sets of SPC floor bodies 3 from easily separating when they are connected.

[0027] Each set of circular grooves 10 is fitted with a sealing sleeve 11, and the sealing sleeve 11 has an auxiliary groove that works in conjunction with the reinforcing frame 12 and the anti-slip side frame 13.

[0028] Specifically, the design of the sealing sleeve 11 and its lower auxiliary groove is to seal the circular groove 10 while avoiding interference with the normal use of the reinforcing frame 12 and the anti-slip side frame 13, and can simultaneously improve the aesthetics. It can also prevent impurities from entering the circular groove 10 and affecting the normal and stable operation of its internal structure.

[0029] Each set of reinforcing frames 12 has horizontal slots on both the front and back, and the protruding ends of the anti-slip side frame 13 on both the front and back are inserted into the horizontal slots.

[0030] Specifically, the design of the transverse groove, combined with the protruding ends on the front and back of the anti-slip side frame 13, allows for sliding and limiting of the anti-slip side frame 13, improving the stability of the anti-slip side frame 13 during movement and preventing deviation or tilting.

[0031] The top of the upper connecting plate 1, the top of the SPC floor body 3, and the top of the sealing sleeve 11 are all on the same horizontal plane.

[0032] Specifically, the design of being on the same horizontal plane improves the flatness of the SPC floor body 3 when it is joined together. This not only enhances the overall aesthetics of the SPC floor body 3, but also prevents protrusions from tripping over users, thus improving safety.

[0033] Each set of vertical shafts 7 has an auxiliary bearing at its top, and the outer ring of the auxiliary bearing is embedded in the upper connecting plate 1.

[0034] Specifically, the design of the auxiliary bearing can help the vertical shaft 7 to rotate stably, avoid obstruction, and position the vertical shaft 7 so that it can only rotate and cannot move up and down, thus improving stability.

[0035] The included angle between the two sets of limiting grooves 15 within each set of circular grooves 10 is 90 degrees.

[0036] Specifically, the design with a 90-degree angle ensures that the snap-fit ​​side plate 8 can stably enter the vertical groove 6 in the initial state without obstruction, and also ensures that the subsequent anti-slip side frame 13 can be stably inserted into the right limit groove 15, thus improving the docking efficiency.

[0037] The specific usage process is as follows: In the initial state, the anti-slip side frame 13 is engaged with the inner limiting groove 15, limiting the initial state of the vertical shaft 7 and the engaging side plate 8. The engaging side plate 8 is set vertically. Then, the user first engages the lower connecting plate 1 in the lower strip groove 4, and the locking plate 2 on the lower connecting plate 1 engages with the locking groove 5 simultaneously. Then, the user engages the upper connecting plate 1 and locking plate 2 with the upper strip groove 4 and locking groove 5 respectively. At the same time, the vertical shaft 7 and the engaging side plate 8 will pass through the vertical groove 6 into the arc groove 9. At this time, the user moves the anti-slip side frame 13, causing it to move outward and compress the spring 14 until it disengages from the inner limiting groove 15, releasing the locking state of the vertical shaft 7. Then, the user rotates the reinforcing frame 12, i.e. The vertical shaft 7 and the snap-fit ​​side plate 8 can rotate synchronously, and the snap-fit ​​side plate 8 will rotate synchronously and snap into the arc groove 9. At this time, the elastic rebound of the spring 14 can drive the anti-slip side frame 13 to move to the right and snap into the right limit groove 15, repositioning the rotated vertical shaft 7, thereby quickly fixing the two sets of connecting plates 1, and then quickly connecting the two sets of SPC floor bodies 3. This utility model, through the setting of auxiliary components, the design of the vertical shaft 7, the snap-fit ​​side plate 8 and the arc groove 9, can initially position the two sets of connecting plates 1, thereby initially positioning the two sets of SPC floor bodies 3. Furthermore, the design of the reinforcing frame 12, the anti-slip side frame 13, the spring 14 and the limit groove 15 can form a system for fixing the vertical shaft 7 and the snap-fit ​​side plate 8. The locking structure of the side plate 8 allows for positioning of the rotated snap-fit ​​side plate 8, ensuring stable engagement with the arc-shaped groove 9. This forms a quick-locking structure for two adjacent sets of SPC flooring bodies 3, with a snap-fit ​​self-locking connection. While ensuring the connection stability of the two sets of SPC flooring bodies 3, this improves the connection efficiency. Furthermore, if a damaged SPC flooring body 3 needs to be replaced, only the connecting plates 1 on both sides need to be removed to replace that set of SPC flooring bodies 3, eliminating the need to disassemble the entire SPC flooring body 3 for replacement. This improves the replacement efficiency and overall convenience of the SPC flooring bodies 3. The efficiency of the connection structure is improved, and the overall functionality of the connection structure is further enhanced. The interlocking of the card plate 2 and the card slot 5 further improves the stability of the two sets of SPC floor bodies 3 when they are connected, and prevents the two sets of SPC floor bodies 3 from easily separating when connected. The design of the sealing sleeve 11 and its lower auxiliary groove can close the circular groove 10 while avoiding interference with the normal use of the reinforcing frame 12 and the anti-slip side frame 13. It can also improve the aesthetics at the same time and prevent impurities from entering the circular groove 10 and affecting the normal and stable operation of its internal structure. The design of the horizontal groove, together with the protruding ends on the front and back of the anti-slip side frame 13, can slide and limit the anti-slip side frame 13, improve the stability of the anti-slip side frame 13 when it moves, and prevent it from shifting or tilting.The design, with the SPC floor body 3 on the same horizontal plane, improves the flatness of the SPC floor body 3 during docking. This not only enhances the overall aesthetics of the SPC floor body 3 but also prevents protrusions that could trip users, thus improving safety. The auxiliary bearing design helps the vertical shaft 7 rotate stably, avoiding obstruction, and also positions the vertical shaft 7 so that it can only rotate and not move up and down, improving stability. The 90-degree angle design ensures that the snap-fit ​​side plate 8 can stably enter the vertical groove 6 in the initial state without obstruction, and also ensures the subsequent stable insertion of the anti-slip side frame 13 and the right limit groove 15, improving docking efficiency.

The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
