Description

Technical Field

[0001] This utility model relates to the field of floor installation technology, and in particular to a rotatable and adjustable floor clip and the ground on which the floor clip is installed. Background Technology

[0002] In the field of flooring installation, including solid wood, wood-plastic composite, and aluminum alloy composite flooring, the stability of the connection between the flooring and the subfloor directly affects the lifespan of the overall structure. Traditional flooring positioning methods often rely on screws directly locking the flooring onto the subfloor. This method is not only inefficient and cumbersome to install, but the screws are also prone to damaging the subfloor substrate itself under repeated fixing or stress, affecting its long-term load-bearing capacity and service life.

[0003] In the prior art, Chinese invention patent application number 201310020464.4 discloses a rotary key mounting structure, including a first key, a second key, and a keel. The first key is connected to the screw hole of the second key connection part by a self-tapping screw, forming a rotary key with the second key. The rotary key is installed in a groove in the keel and can slide and rotate within the groove. The rotary key structure is introduced to optimize installation efficiency and adaptability. After the rotary key is embedded in the keel groove, a basic angle rotation of 90° can be achieved by utilizing the chamfer of the key seat and the cooperation of the groove, while allowing sliding within the groove, significantly improving the installation error tolerance.

[0004] However, the chamfered design of the card slot and the rectangular cross-section of the keel groove form a mechanical angle limit, which can achieve a preset discrete 90° angle. However, for special laying scenarios with non-orthogonal angles, this structure cannot provide smooth and continuous angle adjustment capabilities. Its inherent properties lack the flexibility to cope with complex or personalized installation layouts. Utility Model Content

[0005] The present invention aims to solve the technical problem of insufficient adaptability of existing positioning components to various scenarios.

[0006] To achieve the above objectives, according to one aspect of the utility model, a rotatable adjustable floor clip is provided, comprising: a base for fixing to a foundation joist, the lower end of the base being engaged with the foundation joist and forming a limiting position; a rotatable connector for fixing the floor and rotatably mounted on the base; the base having a through first mating hole; the rotatable connector having a second mating hole, the central axes of the first mating hole and the second mating hole coinciding to form a rotation axis of the rotatable connector relative to the base; and a fastener penetrating the first mating hole and the second mating hole for locking the relative position of the rotatable connector and the base.

[0007] As a preferred embodiment of the above technical solution, the lower end of the base is symmetrically provided with two sets of locking feet, which engage and limit the positioning of the foundation keel. Each set of locking feet is provided with a stress relief groove to divide the locking feet into two independent deformation segments.

[0008] As a preferred embodiment of the above technical solution, the clamping foot has a guide portion extending obliquely to guide the two sets of clamping feet to produce elastic opposite deformation to reduce insertion resistance; the inner side of the clamping foot is also provided with a limiting portion, which abuts against the side wall of the keel after the clamping foot is engaged with the foundation keel, thereby limiting the longitudinal displacement of the clamping foot.

[0009] As a preferred embodiment of the above technical solution, it further includes a connecting boss, which protrudes downward from the bottom of the base, and the first mating hole penetrates the connecting boss.

[0010] As a preferred embodiment of the above technical solution, the rotating connector is provided with two inserts that fit into the groove of the floor, and the inserts are symmetrically arranged with a reference plane as the symmetrical surface.

[0011] As a preferred embodiment of the above technical solution, the upper end face of the insert is further provided with a reinforcing rib, and both ends of the reinforcing rib have guiding inclined surfaces, which are used to guide the insert to be gradually inserted into the floor groove.

[0012] As a preferred embodiment of the above technical solution, the insert is disposed near the outer edge of the rotating connector, and the outer surface of the insert is provided with a slot positioning protrusion.

[0013] As a preferred embodiment of the above technical solution, the insert is disposed near the outer edge of the rotating connector, and a gap positioning piece is disposed between the two inserts. The gap positioning piece extends along the edge direction of the rotating connector and protrudes from the rotating connector, and a gap is maintained between the gap positioning piece and the insert.

[0014] As a preferred embodiment of the above technical solution, a pair of second locking holes are symmetrically provided on both sides of the second mating hole on the rotary connector; the central axis of the first mating hole and the central axis of each of the first locking holes are both located in the reference plane; and the base is provided with two second locking holes that mate with the two first locking holes.

[0015] A type of flooring, comprising a floorboard, a foundation joist, and a rotatable and adjustable floor clip as described in any of the above technical solutions, characterized in that the foundation joist has a first mating groove extending axially to mate with the base, and the floorboard has second mating grooves extending axially on both sides to mate with the rotating connector.

[0016] In summary, this utility model has the following advantages:

[0017] This utility model breaks through the traditional 90° angle limitation by using a rotating shaft system formed by coaxial mating holes and through fasteners, providing continuous stepless angle adjustment capability within the range of 0-90°, perfectly adapting to complex scenarios such as non-orthogonal paving; by utilizing the integrated rotating locking design, it not only improves the torsional load resistance performance, but also completely avoids puncture damage to the keel, significantly improving installation efficiency and structural durability.

[0018] Furthermore, a stress relief groove is opened in the middle of the clamp foot, dividing the clamp foot into two independent deformation sections. In practical applications, this can significantly reduce the installation force and improve the installation efficiency.

[0019] Furthermore, this embodiment optimizes the design by creating floor clips that are compatible with different types of flooring installations. The initial clips use gap positioning pieces or protrusions to prevent uneven seams and ensure the aesthetics of the flooring. More importantly, they provide drainage gaps to facilitate outdoor drainage.

[0020] Further or other beneficial effects will be discussed in the embodiments. Attached Figure Description

Detailed Implementation

[0031] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0032] The present invention will be further explained below with reference to the embodiments:

[0033] Example 1:

[0034] A rotatable and adjustable floor clip, see reference. Figure 1 , Figure 2 , Figure 6 and Figure 7 The system includes a base 100 and a rotating connector 200. The base 100 is connected to the foundation joists 400 via locking feet 110 at its lower end. The rotating connector 200 is rotatably mounted above the base 100. The base 100 has two symmetrically distributed locking feet 110 at its bottom. Each locking foot 110 has an inclined guide portion 111 and a vertical limiting portion 112. During installation, the guide portion 111 causes the two sets of locking feet 110 to elastically deform and engage with grooves in the foundation joists 400. The limiting portion 112 then abuts against the inner wall of the groove to limit longitudinal displacement. Each locking foot 110 has a stress-relieving groove 113 in the middle, dividing it into two independent deformation sections to improve elastic adjustment capability.

[0035] The symmetrical locking feet 110 structure at the lower end of the base 100 and its inner limiting part 112 play a key role in the engagement process with the foundation keel 400. When the base 100 presses against the foundation keel 400, the obliquely arranged guide part 111 on the locking feet 110 uses contact force to cause the elastically deformed locking feet 110 to automatically retract inward, effectively reducing the resistance to installation and insertion. Once the locking feet 110 are fully engaged in the groove on the keel, the limiting part 112 on the inner side of the locking feet 110 will firmly abut against the side wall of the keel, thereby forming a reliable stop and limit in the longitudinal direction, significantly improving the ability of the base 100 to resist longitudinal pull-out force during movement. In particular, the stress relief groove 113 designed on the locking feet 110 divides each locking foot 110 into two independent deformation sections, which allows the entire structure to ensure strength while enabling installers to complete the insertion of the entire locking foot 110 with less force.

[0036] The base 100 has a through first mating hole 101 inside, and the rotating connector 200 has a second mating hole 201. The central axes of the first mating hole 101 and the second mating hole 201 coincide, forming a rotation axis for the rotating connector 200 relative to the base 100. The floor clip of this application also includes a fastener 300, which passes through the first mating hole 101 and the second mating hole 201. In this application, the fastener 300 is a bolt or screw. When the fastener 300 is not fully tightened, it can act as a rotating pin for the rotating connector 200. When the fastener 300 is tightened, it locks the relative position of the rotating connector 200 and the base 100. Furthermore, in this application, the base 100 has a downwardly protruding connecting boss 120 in the center, which is also penetrated by the first mating hole 101. This further enhances the connection strength. The downward-protruding connecting boss 120 at the bottom of the base 100 not only increases the rigidity of the base 100 itself, but more importantly, the first mating hole 101 penetrating the connecting boss 120 effectively increases the thread depth or contact area between the fastener 300 and the mating hole. This design significantly improves the stability and reliability of the connection between the base 100 and the fastener 300 when high locking torque is applied or when subjected to rotational torque, reducing the risk of thread wear or stripping.

[0037] Embedded members 210 are symmetrically arranged on both sides of the surface of the rotary connector 200, and are symmetrically distributed about a reference plane passing through the axis of rotation. The embedded members 210 are close to the edge of the rotary connector 200 and are used to snap into the grooves on both sides of the floor 500.

[0038] Example 2:

[0039] Based on Example 1, referring to Figure 5The upper surface of the insert 210 is provided with reinforcing ribs 211, and the two ends of the reinforcing ribs 211 are machined into bevels to allow them to gradually slide into the groove of the floor. The reinforcing ribs 211 enhance the bending strength of the insert 210 itself, preventing plastic deformation or breakage when it is inserted or subjected to weight. The guiding bevels 2111 at both ends of the reinforcing ribs 211 serve to guide the insert 210 to gradually and smoothly transition into the groove of the floor when the floor is installed, improving the connection strength between the two and effectively preventing damage to components or cracking of the floor edges caused by forceful insertion.

[0040] Example 3:

[0041] Based on Example 1, referring to Figure 4 The insert 210 is located near the outer edge of the rotating connector 200, and the outer side of the insert 210 is provided with a gap positioning protrusion 220. The gap positioning protrusion 220 is used to separate two adjacent floorboards so that a gap is maintained between the floorboards.

[0042] Example 4:

[0043] Based on Example 1, referring to Figure 3 The insert 210 is located near the outer edge of the rotating connector 200, and a gap positioning piece is provided between the two inserts 210. The gap positioning piece extends along the edge direction of the rotating connector 200 and protrudes from the rotating connector 200. A gap 231 is maintained between the gap positioning piece and the insert 210. In addition, a weight reduction hole is provided on the gap positioning piece of the rotating connector 200.

[0044] Examples 1 and 4 are metal parts made of metal materials through processes such as stamping and bending; Examples 2 and 3 are plastic parts made through injection molding. Therefore, Examples 2 and 3 are easy to manufacture with beveled reinforcing ribs 211 and gap positioning protrusions 220. Examples 2 and 3 are easier to mass-produce, while Examples 1 and 4 have higher production costs but also relatively higher structural strength.

[0045] In terms of application structure, Embodiments 1 and 2 are designed as intermediate clamping components, with their rotating connectors 200 located and connected between the grooved sides of two adjacent floorboards 500. Embodiments 3 and 4 are designed as starting clamping components, with their rotating connectors 200 used to connect two vertically arranged floorboards 500, such as... Figure 8 , Figure 9 ( Figure 8 and Figure 9This paper only demonstrates the mating effect of the clips and base plate in Embodiments 1 and 4 (the effects of Embodiments 2 and 3 are the same). Given that the flooring 500 typically only has grooves on its long sides and no groove interface on its short sides, the flooring clips of this application are particularly suitable for outdoor environments. For the intermediate clips, their structure naturally creates a gap between two adjacent flooring pieces 500. This gap not only helps improve the visual effect of the installation but, more importantly, provides a drainage gap, facilitating outdoor drainage. However, for the initial clips, if the gap positioning protrusion 220 is not provided or if no design gap is maintained between the gap positioning piece and the insert 210, the aesthetic effect at the connection point of the flooring 500 may be affected.

[0046] In both Embodiment 1, Embodiment 2, Embodiment 3, and Embodiment 4, a pair of locking holes are symmetrically provided on both sides of the second mating hole 201 on the rotating connector 200. The central axis of the first mating hole 101 and the central axis of each first locking hole 102 are located in the reference plane. The base 100 is provided with two corresponding second locking holes 202 that mate with the two locking holes. This structure realizes the functional transformation of the rotating connector 200, enabling it to serve as a fixed-angle floor support in conventional laying mode, as well as an adjustable support to meet the needs of laying at any angle.

[0047] When standard aligned textured flooring needs to be laid, this support can be easily locked at a fixed angle to ensure better alignment. Meanwhile, customers can precisely adjust and fix the rotating connector 200 at any angle between 1° and 90° (e.g., but not limited to 5°, 10°, 20°, 35°, 45°, etc.) to meet the requirements of personalized or complex flooring patterns.

[0048] For floor gap control, a gap positioning protrusion 220 can be provided on the outside of the insert 210, or a gap positioning plate can be installed between two inserts 210. The positioning plate extends protrudingly along the edge of the rotating connector 200, and the plate body has a reserved through hole for connection with other components.

[0049] Example 5:

[0050] A type of floor includes a floor 500, a foundation joist 400, and a rotatable adjustable floor 500 clip as described in embodiments 1 to 4. The foundation joist 400 has a first mating groove 401 extending axially on it to mate with a base 100, and the floor 500 has second mating grooves (not shown in the figure) extending axially on both sides to mate with a rotating connector 200.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0052] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
