DETAILED DESCRIPTION

[0037] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0038] First embodiment

[0039] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic structural diagram of a first embodiment of a recycled PVC calcium plastic floor provided by the present invention; Figure 2 for Figure 1 The schematic diagram of the pressing plate structure shown; Figure 3 for Figure 1 The schematic diagram of the bottom plate structure shown; Figure 4 for Figure 2 An enlarged schematic diagram of part A is shown; Figure 5 for Figure 3 An enlarged schematic diagram of part B is shown; Figure 6 for Figure 4 The schematic diagram of the limit assembly structure is shown. A recycled PVC calcium plastic floor comprises: a substrate 1;

[0040] A bottom plate 3, the bottom plate 3 is arranged at the bottom of one end of the base plate 1, positioning grooves 31 are provided at both ends of the top of the bottom plate 3, an insertion groove 32 is provided in the middle of the top of the bottom plate 3, a first limiting groove 34 is provided at the bottom of the inner side of the insertion groove 32, and first sliding grooves 33 are provided at both ends of the top of the first limiting groove 34;

[0041] A pressing plate 4, the pressing plate 4 is fixedly mounted on the top of the other end of the base 1, positioning blocks 41 are fixedly mounted on both ends of the bottom of the pressing plate 4, a receiving slot 42 is opened in the middle of the top of the pressing plate 4, a second limiting slot 43 is opened at the bottom of the inner side of the receiving slot 42, and second sliding slots 44 are opened at both ends of the top of the second limiting slot 43;

[0042] A limiting component 5, wherein the limiting component 5 is arranged on the inner side surface of the insertion slot 42;

[0043] The decorative layer 2 is adhered to the top of the pressing plate 4 and the base plate 1 respectively.

[0044] An adhesive layer is arranged at the bottom of the decorative layer 2 for adhering to the substrate 1 , and a decorative pattern is arranged at the top, and the decorative pattern can be selected according to different usage conditions.

[0045] The limiting assembly 5 includes a top plate 51, an insertion head 52, an elastic groove 53, a clamping block 54, a limiting block 55, and a rotating groove 56. The top plate 51 is arranged on the inner side of the insertion groove 42, the insertion head 52 is fixedly installed at the bottom of the top plate 51, and the bottom of the insertion head 52 extends to the bottom of the pressing plate 4, the elastic groove 53 is opened inside the insertion head 52, the clamping block 54 is fixedly installed on both sides of the insertion head 52, and the limiting blocks 55 are fixedly installed on both sides of the top plate 51.

[0046] The limiting block 55 is clamped on the inner side surface of the second limiting groove 43 , and acts on the top plate 51 to limit the position of the top plate 51 on the inner side surface of the insertion groove 42 .

[0047] When the floor leaves the factory, the limiting component 5 is clamped on the inner side of the insertion groove 42. During installation, it is only necessary to insert the insertion head 52 into the inner side of the insertion groove 32. When the insertion head 52 is inserted into the inner side of the insertion groove 32, the insertion head 52 will deform toward the inner side of the elastic groove 53, thereby facilitating the bottom of the clamping block 54 to abut against the top of the bottom plate 3 and be inserted into the inner side of the insertion groove 32, until the clamping block 54 is clamped into the inner side of the first limiting groove 34, thereby limiting the position between the two base plates 1.

[0048] The rotating groove 56 is opened on the top of the top plate 51 , and the rotating groove 56 is in the shape of a cross.

[0049] By configuring the rotating groove 56 to be cross-shaped, it is convenient to use a tool to rotate the top plate 51 later.

[0050] The thickness of the pressing plate 4 is half of the thickness of the base plate 1 , and the pressing plate 4 and the bottom plate 3 have the same size.

[0051] When the decorative layer 2 is damaged after long-term use, the user can remove the decorative layer 2 from the top of the substrate 1, and then take out a new decorative layer 2 and adhere it to the top of the substrate 1, thereby replacing the decorative layer 2;

[0052] When the substrate 1 is damaged, the user first removes the decorative layer 2 from the top of the substrate 1, and then uses a tool to insert it into the inner side of the rotating groove 56 to rotate the top plate 51, so that the top plate 51 drives the insertion head 52 and the limit block 55 to rotate, so that the limit block 55 rotates on the inner side of the second limit groove 43, and the clamping block 54 rotates on the inner side of the first limit groove 34, until the limit block 55 rotates to the bottom of the second slide groove 44, and the clamping block 54 rotates to the bottom of the first slide groove 33, and then the user can move the top plate 51 upward, thereby driving the insertion head 52 to move out from the inner side of the insertion groove 32, and then the user can disassemble the substrate 1 that is limited together, so as to replace the substrate 1.

[0053] The working principle of a recycled PVC calcium plastic floor provided by the present invention is as follows:

[0054] When in use, the user presses the pressing plate 4 on one base plate 1 onto the bottom plate 3 of another base plate 1, and the insertion head 52 is inserted into the inner side of the insertion groove 32, and the two clamping blocks 54 are clamped into the inner side of the first limiting groove 34, so as to limit the position between the two floor plates;

[0055] When two floors are spliced ​​together, the positioning block 41 can be inserted into the inner side of the positioning groove 31 to guide and align the two floors.

[0056] Compared with the related art, the recycled PVC calcium plastic floor provided by the present invention has the following beneficial effects:

[0057] By inserting the positioning block 41 into the inner side of the positioning groove 31, the two floors can be guided and aligned, thereby avoiding the use of magnets for magnetic attraction and guiding, and avoiding the subsequent rusting that affects the aesthetics of the floor.

[0058] And by pressing the pressure plate 4 on the top of the base plate 3, the limiting component 5 is inserted into the inner side of the insertion groove 32, and the limiting component 5 and the first limiting groove 34 are clamped together, so as to limit the pressure plate 4 and the base plate 3. The user does not need to manually rotate the screws, which not only reduces the operation steps but also increases the paving efficiency.

[0061] Specifically, the second embodiment of the present application provides a recycled PVC calcium plastic floor, which is different in that a limiting member 6 is provided on the adhesive surface of the decorative layer 2 .

[0062] The bottom of the limiting member 6 is disposed on the inner side of the receiving groove 42 , and the outer side of the limiting member 6 is in contact with the inner side of the receiving groove 42 .

[0063] The bottom of the limiting member 6 abuts against the top of the top plate 51 .

[0064] A cross protrusion is provided at the bottom of the limiting member 6 , and the cross protrusion is adapted to the rotating groove 56 .

[0065] The working principle of a recycled PVC calcium plastic floor provided by the present invention is as follows:

[0066] When the decorative layer 2 is adhered to the substrate 1 and the top of the pressing plate 4, the positioning piece 6 will be inserted into the inner side of the insertion groove 42, and the cross pattern at the bottom will be inserted into the inner side of the rotating groove 56, thereby limiting the position of the limiting component 5 to avoid displacement of the limiting component 5 during subsequent transfer and transportation.

[0067] Compared with the related art, the recycled PVC calcium plastic floor provided by the present invention has the following beneficial effects:

[0068] The cross pattern at the bottom of the positioning member 6 is inserted into the inner side of the rotating groove 56 , so that when in use, it can limit the position of the limiting component 5 so that the limiting component 5 can be directly inserted into the inner side of the insertion groove 32 later.
