Abstract

The utility model discloses an automatic interlinked hasp floor which is composed of sliver-shaped plate bodies. The side surfaces of the sliver-shaped plate bodies, which are parallel to each other, are respectively provided with a tenon and a rabbet. The utility model is characterized in that the long side surface of the plate bodies is provided with an automatic hasp structure; the short side surface of the plate bodies is provided with an interlinked hasp structure. Different hasp structures are arranged at the long side and the short side of the sliver-shaped floor by the utility model, wherein the interlinked hasp structures which are positioned at the short side can be stressed in a balanced way; the automatic hasp structure can be automatically slide to the spliced position when the automatic hasp structure is installed by that the tenons are aligned to the rabbets by a certain angle, and the tenons are inserted into the rabbets in a slant direction, so the utility model can be convenient for paving; meanwhile, the interlinked hasp structures of the short side are composed of two sets of reversed tenons and clamping grooves which can form interlinked gasps during splicing, the spliced integrity of the fool can be ensured and the floor can be free from cracks.

Description

Automatic a chain of latch floor

Technical field

The utility model relates to a kind of floor, is specifically related to the floor that a kind of employing erection method that has tenon and tongue-and-groove structure is installed.

Background technology

In the prior art, for ease of mating formation of floor, various forms of assembled floors have appearred, particularly laminated flooring wherein generally is made of multilayer, and its top layer is a wearing layer, and made paint usually and handled, after mating formation, the floor can use, can shorten the construction period.This class floor generally has tenon and tongue-and-groove structure, when mating formation, tenon snaps in the tongue and groove, the floor is fixed, be difficult for after finishing looseningly in order to make the floor mating formation, correspondence is provided with buckle structure on tenon and tongue and groove, angular turn or engagement tool by the floor when mating formation make tenon enter tongue and groove, after the completion, buckle structure can block the floor, makes it can not throw off.

For the planarization and the globality that guarantee floor covering layers, the cooperation between buckle structure is tighter usually, the floor covering layers difficulty.For addressing this problem, people have carried out various improvement to buckle structure, so that under the prerequisite that guarantees the snap close effect, make that tenon is easy to enter in the tongue and groove.Yet, since the limitation of thinking, present various latch floors, and per two groups of parallel edges constitute one group of tenon-tongue-and-groove structure in its four limit, two groups of tenon-tongue-and-groove structures are identical, and when mating formation,, reduce distortion for guaranteeing the floor planarization, adjacent floor is adopted dislocation to arrange and is laid, thereby two groups of limits are difficult to accomplish all realize laying to rotate than wide-angle, thus the difficulty that causes the floor to mat formation.

Summary of the invention

The utility model purpose provides a kind of latch floor, under the prerequisite of the floor globality after guaranteeing floor lock button intensity and installation, makes things convenient for mating formation of floor.

For achieving the above object, the technical solution adopted in the utility model is: a kind of automatic a chain of latch floor, constitute by the strip plate body, on the side that is parallel to each other of strip plate body, be respectively equipped with tenon and tongue and groove, the long side of described plate body is provided with the automatic locking buckle structure, the short side of described plate body is provided with the chain lock buckle structure, described automatic locking buckle structure is, described tenon is positioned at the top edge on floor, the tenon lower surface is circular-arc projection, is groove between circular-arc projection and floor plate body, and described tongue and groove is positioned at the lower edge of floor opposite side, which is provided with the arc-shaped groove that cooperates with described tenon, the arc-shaped groove outside is projection upwards; Described chain lock buckle structure is, in a described side surface direction, 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.

In the technique scheme, the cross sectional shape of the circular-arc projection in the described automatic locking buckle structure is less than semicircle; The outer side edges upper end of described circular-arc projection protrudes from the upper edge of tenon, forms buckle structure with the corresponding position of caving on the tongue and groove; Form the slit between the lower limb of tongue and groove and tenon sunken inside edge in the described automatic locking buckle structure.

In the technique scheme, the plate body top in the described chain lock buckle structure is slightly larger than the tenon width that the plate body bottom raises up to the tenon width of lower convexity, and has groove on described plate body top on the tenon lower surface of lower convexity.

Further technical scheme, described plate body bottom are closely blocked ditch one side to the tenon of protrusions and are provided with the inclined-plane.

In the technique scheme, form the slit between the edge of described tenon down and the edge of last Ka Gou.

As a kind of change example, can be provided with chamfering at the four side place of described floor covering.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1. because the utility model is provided with different buckle structures on the long limit on strip floor with minor face, wherein, the chain lock buckle structure energy force balance of minor face, and the automatic locking buckle structure on long limit when mounted, as long as make tenon aim at the oblique insertion of tongue and groove with certain angle, the assembly unit of can sliding automatically puts in place, thereby mats formation conveniently;

2. the chain lock buckle structure of the utility model minor face is made of 2 groups of reverse tenon-Ka ditches, can form a chain of snap close during assembly unit, has guaranteed the globality of floor assembly unit, avoids the floor cracking.
