Abstract

The utility model relates to a coupling structure between boards, in particular to a floor board locking catch. A rabbet is arranged at one side of the board body, a slot is arranged at the other side of the board body, the slot matches with the rabbet, a groove which allows the rabbet to produce flexible deformation is cut on the rabbet, a locking mechanism which can cause the rabbet and the slot to lock each other is arranged at the joint of the rabbet and the slot. When the rabbet is lodged into the slot, the rabbet is pressed by the two sides of the slot, then the rabbet produces reducible deformation, the rabbet reset returns to the original position when the rabbet reaches the occlusion point of the locking mechanism, and then the purpose of occlusion is achieved. Due to the groove in the rabbet, the height of the installation face can counteract the pressing force or gap produced by the surface in the groove of the rabbet, and the surface is caused to be level and compact. Above all, after being occluded, the locking catch cannot break off or be loose due to the influence from external force, and the effect is more obvious when the surface is struck to shake.

Description

Floor lock button

Technical field

The utility model relates to the connecting structure between a kind of plate class, is meant a kind of floor lock button especially.

Background technology

Fixing floor in the existing mode that snaps in draw-in groove by the tenon level is carried out is installed difficulty in assembly unit during to the edge, even installation reluctantly also is difficult to when keeping in repair later on take out.Patent 03259766.5 discloses a kind of a chain of latch floor, it has carried a kind of settling mode, constitute to the tenon of lower convexity and adjacent Ka Gou to extension by floor plate body upper side, in another side surface direction in parallel, constitute the tenon that raises up and adjacent Ka Gou by floor plate body lower side to extension, the tenon of one side and Ka Gou cooperate with the Ka Gou and the tenon of the opposite side on adjacent floor respectively, constitute a chain of structure.

But, when using existing floor lock button, no matter be level or angle clamping or vertically clamping up and down on not too smooth ground, because tenon can't deformation, the surface can perhaps the slit occur on the surface because flange appears in extruding, influences the attractive in appearance and life-span of floor.Floor surface can produce vibrations when being subjected to external force on smooth inadequately ground simultaneously, because tenon can't be made deformation accordingly, floor lock button gets loose in vibrations easily.

Summary of the invention

In order to overcome above-mentioned deficiency, a kind of floor lock button is provided, make that the plate body face joint on floor, combination back is tight, in conjunction with firm, snap close also is difficult for getting loose when plate body is subjected to external force to take place to shake between the plate body.

The technical solution adopted in the utility model is: a kind of floor lock button, one side at plate body is provided with tenon, have draw-in groove on the another side, draw-in groove and tenon match each other, on tenon, have and allow that elastically-deformable groove takes place tenon, be provided with the retaining mechanism that tenon and draw-in groove are locked mutually at tenon and draw-in groove junction.

On general strip consolidated floor, such a pair of tenon and draw-in groove are set in the longitudinal direction, a pair of like this tenon and draw-in groove are set on width equally.

Tenon and draw-in groove direction are divided into respect to the plate body plane on floor and are horizontally disposed with and vertically are provided with.

It is because when floor assembly unit during to the edge, the floor lock button installation that level snaps in is difficult, so the tenon and the draw-in groove vertical direction that design on a kind of plate body snap in interlock that the design vertical direction is provided with tenon and draw-in groove.

In order to reduce working (finishing) area, prevent that simultaneously installer's mistake from installing, a tenon face of tenon is less than another tenon face, and the corresponding edge of the draw-in groove that cooperates with tenon is shorter than another edge.

Retaining mechanism on tenon and the draw-in groove at least one locking projections of at least one tenon face of tenon, being provided with or recessed and be provided with in the corresponding section of draw-in groove with this locking projections or recessed be complementary recessed or protruding.

In order further to improve this connecting structure,, inwardly fall an oblique angle at the side of plate body downwards by the surface, make the face joint between the neighboring board body of splicing back form a reverse V-shaped groove down.Can use bonding adhesive or marine glue in reverse V-shaped groove in connection process, further improve connecting forces and water-proof function, the apex angle ss of reverse V-shaped groove is 3～5 degree.

And for plate body is allowed some leeway when installing and expanding with heat and contract with cold, also tight for seam after the surface is installed, inwardly open a notch at the side of plate body by the bottom surface, make the bottom between the adjacent plate body in splicing back form a technology groove.

The beneficial effects of the utility model are: when tenon snaps in draw-in groove, tenon is pushed by the draw-in groove both sides, make tenon rely on the deformation of groove generation reducibility, tenon reduction behind the biting point that arrives retaining mechanism, reach the locking purpose, because the groove in the tenon, the height of installed surface can both be offset in the groove of tenon extruding force or slit that the surface produces, thereby reaches surfacing, tight.The more important thing is that after interlock snap close is not subject to the external force influence and gets loose, effect was more obvious when especially the surface was hit vibrations.
