Abstract

The utility model provides an automatic hasp floor comprises the rectangular shape plate body, is equipped with tenon and tongue-and-groove respectively on a pair of parallel side of the rectangular shape plate body, its characterized in that: the tenon is positioned on the upper edge of the floor, the lower end face of the tenon is an arc-shaped bulge, a groove is formed between the arc-shaped bulge and the floor plate body, the rabbet is positioned on the lower edge of the opposite side of the floor, an arc-shaped groove matched with the tenon is formed in the rabbet, and an upward bulge is arranged on the outer side of the groove. When the utility model is installed, the floor can slide along the arc surface under the action of gravity and can be automatically assembled in place only by obliquely inserting the position of the tenon aligned with the rabbet and then releasing the floor; meanwhile, the floor board after being assembled has good integral connection strength and can form a special decorative style.

Description

Automatic 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

Various forms of assembled floors have appearred in installation and maintenance for ease of the floor, and it generally has tenon and tongue-and-groove structure, during installation, tenon snaps in the floor is fixed, usually and have a skin of paint, thereby needn't paint after installing, can directly use, accelerate the finishing duration greatly.

Existing this class floor, its common form are that at the middle part of floor level the cross section to be set be rectangular tenon and tongue and groove, during assembly unit, snap in the tongue and groove tenon level fixing, but this structure, in assembly unit during to the edge, operating difficulties, simultaneously, the floor of installation is difficult to take out inconvenient maintenance.Therefore, occurred variously on tenon, having certain inclined-plane, and the floor of buckle structure has been set, this class latched floor on the inclined-plane, owing on the tenon certain inclined-plane is arranged, during installation, ground strip tenon one skew back to the tongue and groove of aiming at another floor, is pressed under exerting oneself, tenon can slip in the tongue and groove, in theory, also can obliquely open on this floor, in order to maintenance.Yet, be guaranteeing the planarization and the globality of floor covering layers, buckle structure corresponding on tenon and the tongue and groove is tighter, and require great effort very much when install on the floor, even usually need to beat tenon is entered, also be almost impossible and open.At present, do not see as yet on the market and aly be convenient to install and can sealed complete floor.

Summary of the invention

The utility model purpose provides and does not a kind ofly need external force to beat can to finish installation automatically, automatic latch floor easy to use.

For achieving the above object, the technical solution adopted in the utility model is: a kind of automatic latch floor, constitute by the strip plate body, be respectively equipped with tenon and tongue and groove on the side parallel to each other of strip plate body, described tenon is positioned at the top edge on floor, and the tenon lower surface is circular-arc projection, form groove between circular-arc projection and floor plate body, 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 tenon, and the groove outside is projection upwards.

In the technique scheme, the cross sectional shape of described circular-arc projection is to be advisable less than semicircle.

In the technique scheme, the outer side edges of described circular-arc projection upper end protrude with in tenon, form buckle structure with the corresponding position of tongue and groove depression, thus assurance floor sealed mutually after laying, to obtain globality preferably.

In the technique scheme, form the slit between the lower limb of described tongue and groove and tenon sunken inside edge.

In the technique scheme, described floor covering place dual-side is provided with chamfering.

In the technique scheme, 4 sides on described floor are respectively arranged with two pairs of described tenon-tongue-and-groove structures.

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

1. because tenon downside of the present utility model is a circular arc, during installation, to let go after only needing tenon aimed at the oblique insertion in position of tongue and groove, promptly can slide at action of gravity lower edge arc surface in the floor, and assembly unit puts in place automatically;

2. form buckle structure between the lateral surface of circular arc tenon upper end and tongue and groove, can guarantee the whole bonding strength on floor after the assembly unit;

3. in floor covering place dual-side chamfering, can after splicing, form the slightly shape of depression, give the connection sensation of people's general floorings seam crossing, form certain decorated style.
