Box-like snap close sheet material of Pressing fastener and fastening method

Technical field:

The present invention relates to a kind of snap close sheet material, it can be the sheet material of sliceable assemblings such as floor or wallboard, and particularly side is provided with tenon and tongue-and-groove and can lets sheet material unit sheet material of snap close each other when splicing in the sheet material unit.

Background technology:

Grooved and tongued floor is used quite permanent; Its package assembly is also applied to wallboard or similar sheet material, and modern is that example is explained with the floor, and grooved and tongued floor is easy to assembly and can let and interconnect combination between the sheet material unit; So extensively adopted by the customer; Relevant dealer also does one's utmost studies improvement, and hope can be designed the product that has more practicality, with CN200610201430.5 Chinese invention patent application case; It promptly belongs to a kind of structure-improved of traditional type grooved and tongued floor, and its when assembling can be reclined and combines at same horizontal plane by two sheet material unit mutually; When yet the grooved and tongued floor of this type of traditional type is accomplished in assembling, can between its sheet material unit, form crown distortion or gap space because of sheet material moisture expansion and drying shrinkage phenomenon, product can let the people feel that result of use does not have obvious improvement.

In order to solve this problem; Someone has designed CN01214121.6 China utility model patent case; This structure can fit in two sheet material unit when combining, and a kind of auto-lock function is provided, and two sheet material unit can firmly be connected; But because this kind structure design can't be carried out volume production with the automatic high-speed process equipment, so do not seeing the Related product appearance on the market yet; Another kind of design is promptly like CN02124731.5 and CN201010580430.7 Chinese invention patent case; It is on the joint tongue of sheet material unit and/or link slot, to be coated with viscose glue; So as to the effect that after combination, can combine closely mutually between the sheet material unit is provided, the floor that this class a operation viscose glue of thought combines is bonded fixing after laying, only if destroy the floor tongue-and-groove structure; Otherwise can't disassemble; Assembling utilization separately after this promptly makes such floor to dismantle, the use of viscose glue also can cause negative effect to environment in addition, shows non-perfect design.

The tongue-and-groove structure of another kind of different types has been proposed in CN200520060450.6 and CN201020286029.8 China utility model patent case in addition; Such design provides the combination between two sheet material unit with an arc latched structure; It need not use viscose glue that the combination between the sheet material unit is provided, and has preferable practicality, and only such design must be skewed another sheet material unit side that just can be bonded to a sheet material unit perk when combination; This design has certain puzzlement in the assembling of sheet material unit; Because when it carries out the combination of floor minor face again after long limit, floor combines the location because the floor minor face again perk be skewed, promptly can't assemble; So its floor minor face can only adopt traditional tongue and groove to assemble; And can't reach the effect of snap close, and for example described in the CN200520060450.6 China utility model patent case, the lower body part of its floor, sheet material unit minor face snap close has been cut sub-fraction by a truncation; The level of being beneficial to is knocked in, otherwise promptly can't after long limit, floor combines the location, carry out the combination of floor minor face again.

Be exactly in addition the series such as CN97190692.0 got permission of Uniling Management Pte B.V " floor that constitutes by hardboard material unit and the method for making this sheet material unit " Chinese invention patent case (corresponding to the Unilin Beheer BV of the said firm the U.S. obtain 6; 874; Wait series " Floor panels with edge connectors " United States Patent (USP) case for No. 292); Surplus this series of patents application case has 20 so far; Its basic framework is all identical, and it has the coupling part that is made up of tongue and groove, and on this coupling part, is provided with whole mechanical locking; Throwing off with being parallel to interconnect on the following direction in sheet material unit perpendicular to relevant edge to prevent two interconnective sheet material unit; Certainly, but its characteristic be to be arranged on protuberance on the tongue soffit, be arranged on groove and the following projection of elastic buckling on the following projection of groove, allow it to interconnect when letting it relatively pass described sheet material unit with a kind of planar fashion.After can going in the sheet material groove by the tongue oblique cutting when this design lets the sheet material unit interconnect; With the ligule tenon is that the fulcrum rotation mode that sheet material presses down and pass mutually on the plane interconnects; And prevent to throw off by its mechanical locking, because it is to adopt the mode that rotation presses down, pass mutually on the plane to carry out the assembling between the sheet material unit, so when after long limit combines the location, carrying out the combination of minor face again; Still but horizontal sliding combines, and has its practicality really.Only this kind design is when the mode that adopts the plane to pass is each other assembled connection sheet material unit; It must be to strengthen the following projection elastic deformation that horizontal sliding strength forces groove; This promptly needs suitable propelling strength to carry out; Especially adopted the inclination assembling mode on long limit and combined the location by its coupling part and desire to carry out minor face when combining, its minor face can only combine with plane phase driven mode, and this moment, the constructor often must can let corresponding minor face be assembled to the location with the mode of knocking by other side; It promptly has inconvenience in operation; The following projection of one side tongue that also might when knocking, will be knocked simultaneously or groove damages, and then has influence on follow-up sheet material assembly working, and obviously it still has necessity of improving.

Seen on the market latched floor in addition at present, though the tenon that each tame manufacturer adopted, groove structure are different, the shape of these floors set tenon, groove on tenon, groove and minor face set on its long limit is also inequality; With CN200520060450.6 China utility model patent case; Snap close main body on its long limit is an arc latched structure, and only such design must be skewed another sheet material unit side that just can be bonded to a sheet material unit perk when combination, when this design is assembled in the sheet material unit; Its long limit, floor be with perk skewed be bonded to the location after; When carrying out the combination of floor minor face again because the floor minor face again perk be skewed, promptly can't assemble; So its floor minor face can only adopt various structure; The lower body part of floor, the sheet material unit minor face snap close in this patent case has been cut sub-fraction by a truncation, and the level of being beneficial to is knocked in, otherwise promptly can't after long limit, floor combines the location, carry out the combination of floor minor face again; This promptly makes manufacturer must adopt the knife-edge cutter of more different structure designs can carry out tenon, the groove processing of different structure; Certainly; The cutter of different knife-edges certainly will increase cutter when processing installs and the inconvenience of adjusting, and this also is existing sheet material tenon, the existing design disappearance of groove structure.
