Description

Technical Field

[0001] This utility model relates to the field of plastic flooring technology, and in particular to a plastic flooring with a quick assembly structure. Background Technology

[0002] Plastic flooring is a type of floor covering material made primarily of plastic. Its diverse performance advantages have led to its widespread use in various settings. Common types include polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP). Among these, PVC plastic flooring is the mainstream product on the market, boasting excellent wear resistance, impact resistance, and corrosion resistance. It also offers a wide variety of colors and styles, mimicking the appearance of wood, stone, carpet, and other materials to meet diverse interior design needs.

[0003] For example, a plastic floor with a quick-assembly structure, disclosed in CN217581043U, includes a main body, a quick-assembly structure, a dust drain channel, snap-fit ​​parts, snap-fit ​​grooves, dust drain holes, and dust scraper strips. The snap-fit ​​parts and snap-fit ​​grooves are interlocked. Because the floor can be assembled quickly and has a simple structure, the main body of the floor can be disassembled periodically to clean the dust on the ground and then the main body of the floor can be reassembled.

[0004] The two assembly methods for plastic flooring described above have drawbacks. The first method, where the panels are snapped together from top to bottom, relies solely on the elasticity of the locking protrusions to adhere to the locking groove, resulting in weak longitudinal pull-out resistance. This makes them prone to detachment under upward forces or uneven ground. The second method, where panels are snapped together at an angle and then laid flat, carries the risk of incomplete locking. This is primarily due to improper control of the tilt angle by the operator. An excessively large angle can lead to excessive wear on the locking components, while an excessively small angle fails to achieve effective engagement. Unevenness of the ground surface can also cause this problem, resulting in some panels appearing assembled but not actually properly locked, making it difficult to meet the stability requirements under complex external forces, environmental changes, and long-term use. Therefore, a plastic flooring system with a quick-assembly structure needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a plastic floor with a quick-assembly structure to solve the problems of weak longitudinal pull-out resistance, easy detachment due to external force or uneven ground, and loose fastening due to angle or ground issues in the two plastic floor assembly methods mentioned above.

[0007] This utility model embodiment adopts the following technical solution: a plastic floor with a quick-assembly structure. It mainly includes at least one set of plastic flooring unit one, with at least one set of plastic flooring unit two on one side. Both plastic flooring unit two and plastic flooring unit one have mating grooves on the same side. Both plastic flooring unit two and plastic flooring unit one have mating blocks on the side away from the mating grooves. The mating blocks are irregularly shaped with protrusions and have outwardly extending steps on their outer sides. The bottom surfaces of adjacent sides of plastic flooring unit one and plastic flooring unit two have notches. An assembly assembly is connected to the notches of the plastic flooring unit one and plastic flooring unit two. The assembly assembly includes a mating part for initial connection and lateral bracing of adjacent flooring units, and a limiting part for further reinforcing and locking the adjacent plastic flooring units.

[0008] Furthermore, the assembly includes a mating part fixed at the notch, the mating part including a crossbar fixed to the inner wall side of the notch of the plastic flooring, the crossbar extending horizontally and leaving a gap with the bottom of the notch to form a sandwich space for mating.

[0009] Furthermore, a slide rail plate is fixed to the bottom surface of the plastic flooring. The slide rail plate is elongated and parallel to the side of the flooring. A connecting plate is slidably fitted onto the slide rail plate. The connecting plate is inverted L-shaped. The vertical section of the connecting plate is used to connect the crossbar, and the horizontal section is adapted to the slide rail plate. A T-shaped sliding protrusion is fixed to a local position on the bottom surface of the connecting plate. A long sliding groove is provided on the slide rail plate to accommodate the sliding protrusion. The long sliding groove is elongated and parallel to the slide rail plate.

[0010] Furthermore, the connecting plate is threaded with a thumb screw on its side, and the slide rail plate has a matching screw hole on its side.

[0011] Furthermore, the limiting part includes a limiting sleeve fixed to the crossbar. The limiting sleeve is a hollow cylindrical structure and is fitted onto the corresponding position of the crossbar. A spring is fixed inside the limiting sleeve, and a locking post passes through the center of the spring. The two ends of the locking post pass through the limiting sleeve and the crossbar, respectively. A protruding step extends from the lower end of the locking post. A mating hole adapted to the locking post is provided on the connecting plate. A transverse rotating shaft is fixed to one end of the locking post that passes through the limiting sleeve. A pressure handle is movably connected to the rotating shaft.

[0012] Furthermore, anti-slip pads are provided at the contact positions of the pressing handle and the top of the limiting sleeve, and at the contact positions of the locking post and the docking hole.

[0013] Furthermore, the pressure handle is wrench-shaped.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] A new type of plastic flooring with a quick-assembly structure addresses the weakness in longitudinal pull-out resistance caused by the first type of top-down snap-fit ​​method, which relies solely on elastic bonding. This new method improves pull-out resistance by interlocking the protrusions of the connecting blocks with the connecting grooves, combined with the outer step for limiting. Further reinforcement and locking by the lateral bracing and limiting parts of the assembly components create multiple layers of fixation, significantly enhancing longitudinal pull-out resistance and preventing detachment due to upward external forces or uneven ground. Addressing the issue of loose connections in the second type of inclined snap-fit ​​method due to angle or ground conditions, this new method uses sliding insertion of the connecting blocks and grooves, insertion of connecting plates into the interlayer space, and locking with screw holes and locking posts. This reduces the impact of human operation and ground flatness, ensuring a tight fit without the risk of loose connections. It meets the stability requirements under complex external forces, environmental changes, and long-term use scenarios, while the standardized interface design facilitates quick assembly and expansion.

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-3 As shown in the figure, this utility model provides a plastic floor with a quick-assembly structure, including at least a plastic floor 1, and at least one set of plastic floor 2 on one side of the plastic floor 1. The plastic floor 2 and the plastic floor 1 have similar structures and can be spliced ​​and expanded through standardized interfaces. As can be seen from the drawings, the same side of the plastic floor 2 and the plastic floor 1 are provided with a mating groove 12. The mating groove 12 is a long strip-shaped groove structure that extends parallel to the side. At the same time, on the side of the plastic floor 2 and the plastic floor 1 away from the mating groove 12, a mating block 11 is integrally provided. The mating block 11 is an irregular snap-fit ​​shape with protrusions, and its outer side has an outwardly extending step (not shown in the figure). The size and protrusion shape of the mating block 11 are precisely matched with the mating groove 12. The two form the splicing foundation between the floorboards through a mortise and tenon sliding structure.

[0026] In practical use, utilizing the symmetrical structural design of plastic flooring 1 and plastic flooring 2, the mating block 11 on one side of plastic flooring 1 is aligned with the mating groove 12 on one side of plastic flooring 2, and then slid in and connected parallel to the side of the flooring. Figure 1 From the assembly relationship presented, after the mating block 11 is inserted into the mating groove 12, it can use its own protrusion and the interlocking with the groove, as well as the limiting of the step structure, to restrict the vertical displacement and lateral separation between the floorboards, and quickly complete the splicing of a single set of floorboards; if it is necessary to expand the paving in the future, the sliding insertion method of the mating block 11 + mating groove 12 can be continued to splice the plastic floorboards one by one, and the standardized structure can be used to achieve efficient and stable large-area paving to meet the ground paving needs of different scenarios;

[0027] Multiple sets of reinforcing rods 15 are integrally installed on the bottom surface of both plastic flooring 1 and plastic flooring 2. These reinforcing rods 15 are arranged in parallel to enhance the overall rigidity of the flooring. Simultaneously, notches 14 are formed on the bottom surface of adjacent sides of plastic flooring 1 and plastic flooring 2. These notches 14 have a concave cavity structure, providing installation space for the assembly component 3. Assembly components 3 are connected to the notches 14 on both plastic flooring 1 and plastic flooring 2 for quick assembly of adjacent plastic flooring units. The assembly component 3 includes a mating part fixed at the notch 14. The mating part includes a horizontal bar 31 fixed to the inner wall of the notch 14 on the plastic flooring 2. The horizontal bar 31 extends horizontally and leaves a gap with the bottom of the notch 14, forming a sandwich space for insertion.

[0028] Meanwhile, a slide rail plate 38 is fixed to the bottom surface of the plastic floor 1. The slide rail plate 38 is long and parallel to the side of the floor. A connecting plate 39 is slidably sleeved on the slide rail plate 38. The connecting plate 39 is inverted L-shaped. The vertical section of the connecting plate 39 is used to connect the horizontal bar 31, and the horizontal section is adapted to the slide rail plate 38. A T-shaped sliding protrusion 310 is fixed at a local position on the bottom surface of the connecting plate 39. Correspondingly, a long sliding groove is opened on the slide rail plate 38 to adapt to the sliding of the sliding protrusion 310. The long sliding groove is long and parallel to the slide rail plate 38.

[0029] The connecting plate 39 can slide linearly along the long slide groove via the sliding protrusion 310, and be inserted into the gap between the crossbar 31 and the bottom of the notch 14 to achieve initial connection. In addition, the connecting plate 39 is threaded with a thumb screw 311 on its side, and the slide rail plate 38 has a matching screw hole 312 on its side. When one end of the connecting plate 39 slides into the gap below the crossbar 31, the thumb screw 311 is turned to lock it into the screw hole 312, which can lock and fix the connecting plate 39, strengthen the splicing strength of adjacent floorboards, and prevent displacement or loosening after splicing.

[0030] Furthermore, a limiting part is provided on the crossbar 31. This limiting part includes a limiting sleeve 32 fixed to the crossbar 31. The limiting sleeve 32 is a hollow cylindrical structure and is fitted onto the corresponding position of the crossbar 31. A spring 33 is fixed inside the limiting sleeve 32, and a locking post 34 passes through the center of the spring 33. The two ends of the locking post 34 pass through the limiting sleeve 32 and the crossbar 31, respectively. A raised step 36 extends from the lower end of the locking post 34. At the same time, a mating hole 313 adapted to the locking post 34 is provided on the connecting plate 39. A transverse rotating shaft 35 is fixed to one end of the locking post 34 that passes through the limiting sleeve 32. A pressing handle 37 is movably connected to the rotating shaft 35. The pressing handle 37 is wrench-shaped and serves as the operating end. In addition, anti-slip pads are provided at the contact positions of the pressing handle 37 and the top of the limiting sleeve 32, and at the contact positions of the locking post 34 and the mating hole 313. These anti-slip pads are used to enhance friction and stability.

[0031] In the initial state, the holding handle 37 can rotate around the pivot 35. Pressing down and rotating the holding handle 37 will cause the locking post 34 to move upward, stretching the raised step 36 and compressing the spring 33. At this time, continue to rotate the holding handle 37 so that one end abuts against the top of the limiting sleeve 32, and the lower end of the locking post 34 is flush with the bottom surface of the crossbar 31, leaving space for the insertion of the connecting plate 39. After the connecting plate 39 slides into the gap below the crossbar 31, pull and rotate the holding handle 37 in the opposite direction to the horizontal state. The spring 33 gradually returns to its original state, pushing the locking post 34 downward and accurately locking it into the docking hole 313. Utilizing the engagement of the locking post 34 with the hole, as well as the auxiliary limiting of the anti-slip pad, the splicing and locking of plastic flooring 1 and plastic flooring 2 are further strengthened. Through the linkage of the mechanical structure, the dual fixation of sliding insertion and locking post 34 locking is achieved, improving the anti-pull-out and anti-displacement capabilities of the assembled flooring.

[0032] Working Principle: During use, the symmetrical design of plastic flooring 1 and plastic flooring 2 is utilized. The side connecting blocks 11 and connecting grooves 12 form a mortise-and-tenon sliding foundation. The irregular snap-fit ​​shape of the connecting blocks 11 precisely matches the connecting grooves 12. After insertion, the interlocking of the blocks' protrusions with the groove, along with the limiting effect of the outer stepped structure, initially restricts vertical misalignment and lateral separation between the flooring sections, providing a basic framework for overall splicing. Furthermore, the standardized interface design supports piece-by-piece expansion, meeting the needs of large-area installation. Simultaneously, multiple sets of parallel reinforcing rods 15 on the underside of the flooring enhance its rigidity, laying the foundation for the structural stability after splicing.

[0033] Under the premise of basic splicing, the notch groove 14 on the bottom surface of adjacent floorboards provides installation space for the assembly component 3, and secondary fixation is achieved through the cooperation of the slide rail and the insert plate. The slide rail plate 38 on the bottom surface of plastic floorboard 1 and the inverted L-shaped connecting plate 39 constitute a sliding mechanism. The T-shaped sliding protrusion 310 slides along the straight line of the long slide groove, which can drive the connecting plate 39 to accurately insert into the interlayer space between the crossbar 31 and the bottom of the groove in the notch groove 14 of plastic floorboard 2, forming a lateral connection. When the connecting plate 39 is in place, the thumb screw 311 on the side is turned to lock it into the screw hole 312 of the slide rail plate 38, which can further restrict the sliding of the connecting plate 39. The mechanical fastening strengthens the connection strength of the adjacent floorboards and prevents displacement or loosening due to external force after splicing.

[0034] To achieve a higher level of locking strength, the limiting part on the crossbar 31 is reinforced with a triple structure through the linkage of the elastic structure and the operating components. In the initial state, the rotation of the holding handle 37 can move the locking post 34 upward and compress the spring 33, making the lower end of the locking post 34 flush with the bottom surface of the crossbar 31, ensuring that the connecting plate 39 can be inserted smoothly. After the connecting plate 39 is in place, the holding handle 37 is rotated in the opposite direction to a horizontal state, the spring 33 returns to its original position and pushes the locking post 34 downward, so that it is precisely locked into the mating hole 313 of the connecting plate 39. The engagement of the raised step 36 with the hole wall, combined with the friction of the anti-slip pad, can effectively prevent the locking post 34 from coming out. Through the triple fixing mechanism of sliding insertion + screw hole 312 locking + locking post 34 engagement, the longitudinal pull-out resistance and anti-displacement ability of the floor are improved, solving the problems of easy disengagement and loose locking in traditional assembly methods, and achieving efficient and stable rapid assembly.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
