Description

A triple elastic lock for flooring

technical field

The utility model relates to a floor lock, in particular to a floor triple elastic lock.

Background technique

At present, the biggest feature of the common floor joint locks on the market is to prevent the floor joints from cracking. Whether the floor lock is firm, stable, and durable is mainly determined by factors such as the chamfer area and angle of the lock, processing accuracy, and substrate toughness. The current floor locks can be divided into single locks and double locks according to the number of layers of grooves and tenons. The above two types of floor locks have poor locking force and are easily affected by changes in external cold, heat, dryness and humidity, resulting in seam separation and warping. In order to solve the problems, in the paving process, nails, glue and other methods are needed, resulting in problems such as the floor cannot be directly laid on the ground and repeated disassembly and utilization.

Utility model content

In view of this, the purpose of this utility model is to provide a triple elastic lock for the floor, so that the connection strength of the floor lock is strong, firm, stable and has the effect of comfortable and quiet.

A triple elastic lock buckle for a floor, comprising: a board body, a male tenon and a female tenon, the left and right sides of the board body are respectively provided with a male tenon and a female tenon, and the male tenon of the board body cooperates with the adjacent board body female tenon use.

Further, the male tenon includes: a concave tenon groove, an upper locking plate, a tenon, a first protrusion, a second protrusion, a third protrusion, an elastic rubber layer, and a lower locking plate. One end of the plate body is provided with an upper The lock plate and the lower lock plate, the upper lock plate is provided with a first protrusion, the lower lock plate is provided with a second protrusion and a third protrusion, and a groove is provided between the upper lock plate and the lower lock plate. A tenon is arranged above the locking plate.

Further, the tenon includes: a tenon overlapping part, a first depression, a second depression and a third depression, the other end of the board is provided with a groove, and the upper wall of the groove is provided with a first depression Used in conjunction with the first protrusion, the lower wall of the groove is provided with a second recessed part and a third recessed part to cooperate with the second protrusion and the third protrusion respectively, and the upper part of the groove is provided with a mortise lap part and The tenon and tenon are used together. After the male tenon and the female tenon fit together, there is still an expansion joint between the boards at the bottom of the floor.

Further, the outer wall of one side of the male tenon is provided with an elastic glue layer.

Furthermore, the angle formed by the concave tenon groove and the ground of the board body is 2°-5°.

The beneficial effect of the utility model is that the upper ends of the floor boards are connected by tenons and the inclined device is installed, so that the floor has a certain deformation space, but there are no gaps on the surface, and it is not easy to accumulate dust. The insertion part of the male tenon has a concave tenon groove, and the elastic-plasticity of the wood itself can make the installation more secure, convenient and compact. At the same time, leave a certain amount of space to deal with deformation, effectively prevent bubbling and warping. The first protrusion and the second protrusion corresponding to the upper and lower sides are set on the male tenon, which play a fixed role in the front, rear, upper and lower dimensions, and the connection is more tightened. In addition to the function of fixing the plate body, the third protrusion also has the function of positioning, and the structure is highly consistent, so the stability can be improved, and the tensile strength can be increased. Moreover, this structure makes the spliced floor have the effect of precise splicing and less chance of separation and cracking. A layer of elastic colloid is coated on the surface of the tenon, which can effectively block the contact with the external link, thereby resisting the influence of the external environment, and can also increase the friction force, make the connection tighter and effectively prevent the phenomenon of stress concentration. At the same time, it can play the role of sound insulation, moisture resistance and shock absorption. It is more comfortable to use.
