[0003] This type of splicing floor is easy to lay, but in the process of subsequent use, it was found that when this type of splicing floor is used in certain special occasions, such as occasions where a large horizontal friction force is applied to the splicing floor, for example, when a car passes over the laid splicing floor, the wheels apply a large horizontal friction force to the splicing floor. This friction force will cause the splicing between the hook and the slot to disengage, causing the spliced ​​splicing floors to disengage, affecting normal use.

[0004] Therefore, it is necessary to propose solutions to the problems existing in the prior art. Summary of the invention

[0005] 1. Technical issues to be resolved

[0010] Furthermore, the slot and the hook extend along the edge portion where they are located, and the length of the through slot extending in the slot is longer than the length of the protruding point extending on the top surface of the hook portion.

[0011] Furthermore, the slot and the hook extend along the edge portion where they are located, and the length of the through slot extending in the slot is longer than the length of the hook extending.

[0012] Furthermore, in a direction parallel to the edge portion, a protruding point is provided at each of the two ends of the top surface of the hook portion.

[0031] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] Base plate for tiled floor units

[0033] The present invention provides a bottom plate of a spliced ​​floor unit, such as Figure 2 and Figure 3 As shown, the bottom plate is square, which can be rectangular or square. The bottom plate includes an upper surface 11 and a lower surface 12 that define its thickness. The bottom plate has an edge portion 13 located around it. The edge portion 13 refers to the solid part of the edge around the bottom plate. The card slot 15 is opened in the solid part of the edge of the lower surface 12 of the bottom plate, and the card hook 14 protrudes outward from the edge of the bottom plate. Figure 2 and Figure 3 As shown, the edge portion 13 may be provided with a plurality of hooks 14 protruding outwards, and a corresponding number of slots 15 should be provided on the edge portion 13 .

[0034] Preferably, the upper surface 11 of the base plate and the edge portion 13 are on the same horizontal plane. In this structure, the decorative panel of the spliced ​​floor is arranged on the upper surface 11, and the shape and size of the decorative panel are arranged to be consistent with the shape and size of the base plate. In this way, the decorative panel also covers the edge portion 13 at the same time. In this way, when multiple spliced ​​floors with decorative panels are assembled together, the decorative panels of adjacent spliced ​​floors can be adjacent to each other, thereby forming a complete pattern composed of decorative panels.

[0035] At least one pair of the opposite edge portions 13 is provided with a slot 15, the opening of the slot 15 faces the lower surface 12; a plurality of hooks 14 are extended outward from at least one pair of the opposite edge portions 13 of the bottom plate, and a hook portion 141 (see Figure 1 The hook 14 is suitable for cooperating with the slot 15 on the adjacent bottom plate to splice multiple bottom plates. The improvement of the present invention mainly lies in adding a protruding point on the top surface of the hook portion 141 of the hook 14, and adding a through slot between the bottom of the slot 15 and the upper surface 11. In addition, the other structures are consistent with those disclosed in the Chinese invention patent application specification CN105952107A. For other structures, please refer to the Chinese invention patent application specification CN105952107A, which will not be described in detail in the present invention. The improvements made by the present invention are described in detail below.

[0036] The main improvement of the present invention is: Figure 1 As shown, the hook portion 141 at the end of the hook 14 includes an upward top surface, on which a protruding point 2 protruding upward is provided; the bottom of the slot 15 (i.e., the bottom surface of the slot 15 parallel to the upper surface 11) is provided with a through slot 3 connected from the bottom to the upper surface 11; when the hook 14 cooperates with the slot 15 on the adjacent bottom plate, the protruding point 2 on the hook is located in the through slot 3 of the slot on the adjacent bottom plate.

[0037] Based on the above structure, the present invention provides an upwardly protruding point 2 on the top surface of the hook portion 141 of the hook 14, and provides a through groove 3 connected to the upper surface 11 at the bottom of the groove 15, so that when the hook 14 and the groove 15 cooperate, the protruding point 2 enters the through groove 3; in the previous structure, when the base plates are spliced ​​together, there is only cooperation between the hook 14 and the groove 15, and when the protruding point 2 and the through groove 3 are added, the connection structure between the base plates spliced ​​together increases the cooperation between the protruding point 2 and the through groove 3. After increasing the cooperation between the protruding point 2 and the through groove 3, the contact thickness of the connection structure between the base plates spliced ​​together in the thickness direction of the base plates is also increased, so that the base plates spliced ​​together are not easy to separate.

[0038] The setting of the protruding point 2 can be regarded as raising the hook portion 141 of the hook 14, and the setting of the through groove 3 can be regarded as deepening the depth of the groove 15, so as to increase the contact thickness between the hook 14 and the groove 15 in the thick bottom direction of the bottom plate. However, the inventor found through experiments that when the hook portion 141 is simply raised and the groove 15 is deepened, the hook 14 is difficult to be assembled into the groove 15. At the same time, after the groove 15 is deepened, the distance between the groove bottom of the groove 15 and the upper surface 11 will be reduced, that is, the thickness of the material between the groove bottom of the groove 15 and the upper surface 11 will be thinner, and these materials are used to connect the two groove walls of the groove 15. When the spliced ​​floor is subjected to the horizontal friction force mentioned in the background technology, one of the outer groove walls of the groove 15 is subjected to a horizontal pulling force toward the outside. When this pulling force is large, the material between the groove bottom of the groove 15 and the upper surface 11 will be bent and deformed, and the spliced ​​spliced ​​floor units are still relatively easy to be torn apart. The present invention only sets the protruding point 2. If the protruding point 2 is set, a single protruding point 2 is prone to slight deformation, and the hook 14 is easier to be installed in the slot 15; and the through groove 3 is only set in a local position, so that the material between the bottom of the slot 15 and the upper surface 11 in most areas still maintains the original thickness, and there is no situation where the material between the bottom of the slot 15 and the upper surface 11 is easily bent and deformed, and the effect is better when used.

[0039] In this embodiment, if Figure 5 As shown, the slot 15 extends in a direction parallel to the edge portion 13, and the length of the through slot 3 extending in the slot 15 is longer than the length of the protruding point 2 extending on the top surface of the hook 141. When assembling the base plate provided by the present invention (which is a splicing floor unit after the decorative plate is installed), the hook 14 is first roughly installed into the slot 15, and then one of the base plates is slid in a direction parallel to the edge portion 13 to align the two floors. This assembly method is relatively easy to complete. For this reason, in this embodiment, in the direction parallel to the edge portion 13, the length of the through slot 3 (that is, the length of each section of the slot body in the through slot 3 for accommodating the corresponding protruding point 2) is also set to be longer than the length of the protruding point 2, so that the protruding point 2 can slide in the through slot 3 to achieve the above-mentioned assembly method; at the same time, the length of the through slot 3 is longer than the length of the protruding point 2, which can also effectively prevent the problem that the protruding point 2 cannot completely enter the through slot 3 due to manufacturing errors.

[0040] In this embodiment, if Figure 5As shown, the slot 15 extends in a direction parallel to the edge portion 13, and the length A of the through slot 3 extending in the slot 15 is longer than the length B of the hook 14. Preferably, in a direction parallel to the edge portion 13, a protrusion 2 is provided at both ends of the top surface of the hook portion 141. Providing two protrusions 2 can increase the connection points and improve the stability of the connection. At the same time, as described above, in order to achieve the above-mentioned assembly method, since a protrusion 2 is provided at both ends of the top surface, the length A of the through slot 3 is correspondingly set to be longer than the length B of the hook 14, so that both protrusions 2 can slide in the through slot 3.

[0041] More preferably, if Figures 1 to 3 and Figure 5 As shown, the through slot 3 includes two slot walls located on both sides of the length direction of the through slot 3, the two slot walls are opposite to each other, and a reinforcing rib 31 connecting the two slot walls is provided in the middle of the through slot 3. As mentioned above, it is preferred to set the length of the through slot 3 longer than the length of the hook 14. When the length of the through slot 3 is too long, the material ( Figure 5 The part filled with mesh in the through groove 3 is easily pulled, deformed or even torn. Therefore, a reinforcing rib 31 is provided to connect the two groove walls of the through groove 3. Through the reinforcement of the reinforcing rib 31, the material between the groove wall located outside the through groove 3 and the outermost wall surface of the bottom plate is not easily pulled, deformed or torn. Figure 5 In the structure shown, the through slot 3 referred to herein includes two slot sections and a reinforcing rib located between the two slot sections.

[0042] In this embodiment, if Figure 4 As shown, the protruding point 2 includes an inner side surface 21 facing the edge portion 13, an outer side surface 22 facing away from the edge portion 13, and an upper surface 23 facing the same direction as the upper surface 11. The transition between the outer side surface 22 and the upper surface 23 is provided with a chamfered structure 24, and the inner side surface 21 is a vertical surface. The chamfered structure 24 is provided to facilitate the installation of the hook 14 into the slot 15. The inner side surface 21 is a vertical surface, and the inner side surface 21 contacts the outer side wall of the through slot 3 to achieve contact and abutment.

[0043] In this embodiment, the protrusion 2 protrudes from the top surface of the hook portion 141 by 0.5-2.0 mm. Preferably, the protrusion 2 protrudes from the top surface of the hook portion 141 by 1 mm.

[0044] In the present embodiment, at least the edge portion, the hook and the protrusion of the bottom plate are integrally formed of ABS plastic or PS plastic, that is, the entire bottom plate can be integrally formed of ABS plastic or PS plastic; or only the edge portion, the hook and the protrusion are integrally formed of ABS plastic or PS plastic, and the edge portion, the hook and the protrusion form a square hollow frame, and the square hollow frame is subsequently filled with a filling plate, and the filling plate can be made of a relatively low-cost material to reduce the total manufacturing cost of the entire bottom plate. Of course, in addition to ABS plastic or PS plastic, other engineering plastics can also be used to make the bottom plate have high strength and high stability. At the same time, in the above-mentioned solution in which the entire bottom plate is integrally formed of ABS plastic or PS plastic, the middle part of the bottom plate can be set as follows Figure 2 and Figure 3 The structure of the grid plate shown is to reduce production costs, and of course, it can also be a solid structure to improve strength. The above replacements all fall within the scope of protection of the present invention.
