The specific embodiment
Specify the spliced plastic floor tile of snap close type involved in the present invention below in conjunction with accompanying drawing.Yet, should the present invention be understood as this embodiment that is not limited to following description, and technical concept of the present invention can be implemented with other known technologies or the function other technologies combination identical with those known technologies.
In the following description; For clear structure of the present invention and the working method of showing; To describe by many directionality words; But should with " preceding ", " back ", " left side ", " right side ", " outward ", " interior ", " outwards ", " inwardly ", " on ", Word Understanding such as D score is for making things convenient for term, and be not to be understood that and be word of limitation.In addition; A subaerial side mainly depended in employed in the following description " below " speech; " top " speech mainly refers to the side away from ground, and a side of the center of gravity of nearly object mainly depended in " interior " speech, and " outward " speech mainly refers to the side away from the center of gravity of object.
As shown in fig. 1, Fig. 1 is the primary structure sketch map of the spliced plastic floor tile of snap close type involved in the present invention.The spliced plastic floor tile 100 of this snap close type is made up of main part and stitching section.The spliced plastic floor tile of this snap close type in use, two plastic floor tiles that only need to use certain external force to be close to are fixed and can use.
Fig. 2 is the A-A cross-sectional view of the spliced plastic floor tile of snap close type involved in the present invention.As shown in Figure 2, the spliced plastic floor tile of this snap close type comprises upper surface 11 and soffit 12, and wherein upper surface 11 is for using the surface, and soffit 12 directly contacts with the floor.Because the spliced plastic floor tile of this snap close type in use, two plastic floor tiles that only need the certain external force of use to be close to are fixed and get final product, and therefore, in installing and using process, soffit 12 need not to use any cementing agent.The spliced plastic floor tile of this snap close type also comprises a junction 13, comprises a female groove 15 in the place with these connecting portion 13 adjacency.With these connecting portion 13 corresponding other ends one public tenon 14 is being set.
The splicing sketch map of the spliced plastic floor tile of this snap close type as shown in Figure 3.The consistent spliced plastic floor tile of snap close type of two block structures is in splicing or installation process, and the soffit 12a of two spliced plastic floor tiles of snap close type contacted with ground with the 12b while, and upper surface 11a and 11b almost are positioned at same horizontal plane.The connecting portion 13b of second spliced plastic floor tile of snap close type inserts in the groove of first spliced plastic floor tile of snap close type, and meanwhile the public tenon 14a of the spliced plastic floor tile of the first snap close type inserts the interior 15b of female groove of the spliced plastic floor tile of the second snap close type.So said, in the connection procedure of the spliced plastic floor tile of multi-disc snap close type, can keep relative position to fix each other, be not subjected to displacement.
In order to guarantee that the snap close floor tile does not curl, do not rupture and durable in application process, employed snap close thickness of product is not less than 4.2mm usually in the prior art.Above-mentioned snap close floor tile is because thickness limits causes product monolithic quality heavier; Relatively inconvenience in operating process and transportation and process of deployment; Higher in this external grooving process to floor tile planeness and dimensional requirement; Because floor tile is thicker, the product of batch process is prone to planeness and the inaccurate phenomenon of gauge.What time abovely consider; The present invention provides a kind of snap close floor tile; This snap close floor tile is main with the PVC expanded material; This just largely alleviates the floor tile quality, offers convenience for operation, carrying and installation, in addition PVC foam floor tile have also that intensity height, dimensional stability are good, insulation, sound insulation, characteristic such as fire-retardant.
