Description

Horizontal inserting type love-heart-shaped floor locking structure

Technical Field

The utility model belongs to the technical field of the architectural decoration material, in particular to formula of violently inserting heart-shaped floor hasp structure.

Background

The wood floor has the advantages of beautiful color, various patterns, comfortable foot feeling, good heat preservation effect and the like, and is widely used. The floor lock catch is one of the core technologies of the wood floor. The existing floor lock catch can be divided into an inclined insertion type, a horizontal insertion type and a vertical insertion type according to the installation mode. The horizontal inserting type floor lock catch is simple in structure and easy to produce and process, but due to the fact that a traditional horizontal inserting type floor lock catch is of a non-horizontal stress structure, the problems of seam retreating, noise, instable installation and the like easily occur, and the floor lock catch with the structure is only applied to solid wood composite floors with extremely small deformation.

For example, CN102021993A in the prior art discloses a floor connection structure and a special lock catch, belonging to the technical field of building decoration materials. It includes adjacent first floor and second floor and connects the hasp on first floor and second floor, the adjacent edge on first floor and second floor is equipped with first tongue-and-groove and second tongue-and-groove respectively, the length of first tongue-and-groove is isometric with first floor edge, the length of second tongue-and-groove is isometric with the edge of second floor, the hasp is rectangular form section bar structure, just the length direction of hasp is unanimous with first tongue-and-groove and second tongue-and-groove length direction, the cross section of hasp includes left tenon portion and the right tenon portion of midbody both sides, at least wherein the tip of one of left tenon portion or right tenon portion is formed with the barb, the barb extends to the midbody by the tip of left tenon portion or right tenon portion, just be formed with the seam between barb and left tenon portion body or the right tenon portion body, the first tongue-and groove cooperation on first floor, the right tenon part is matched with the second mortise of the second floor.

This technique can realize that floor one side locks through the barb, and the opposite side is through having the tenon that cracks, through extrusion deformation entering tongue-and-groove inside, the barb structure after kick-backing keeps the locking of tongue-and-groove tenon. The disadvantages are that: 1. although the technology can solve the problem that the floor is easy to fall off, the tenon structure of the slotting structure is difficult to process, and the lock catch is difficult to install after processing and forming; 2. the elastic resilience barb structure leads the lock catch not to be repeatedly installed and disassembled for use.

This structure all has protruding structure's connecting piece to compare from top to bottom with former design, has following 2 obvious advantages:

1. the defect of difficult installation caused by insufficient elasticity of the connecting piece in the original design can be overcome. The former design all has protruding structure from top to bottom, and connecting piece crossbeam major structure and floor tongue-and-groove fully cooperate, guarantee that the installation back connecting piece is stable not rock. If the upper and lower protruding structures are small in size, the connecting piece can be inserted into the mortise slightly by inward deformation, but due to the small-size protruding structures, the horizontal stress is small, and the ideal effect of locking the floor in the horizontal direction cannot be achieved; if the size of the upper and lower protruding structures is large, the elastic modulus of materials such as solid wood and plastics of the connecting piece is large, the inward deformation is limited, the installation is very difficult, and even the connecting piece loses the connecting effect due to the fact that the protruding structures are damaged, the connecting piece balance beam is broken and the like. The improved design adopts a single-side convex structure, the relation between installation and stress is well balanced, and large horizontal tension and easy installation can be realized.

2. The problem of contradiction between the improvement of strength and the increase of elasticity of the connecting piece can be solved. The original design is an upper and lower protruding structure, so that the installation can be easier, the width of the joint of the connecting piece is necessarily reduced, and the larger elasticity is obtained, but the strength of the connecting piece is reduced in the mode, and the service life of the floor lock catch is shortened. The improved design adopts a single-side convex structure, and can be inserted into the floor mortise only by small elastic deformation, so that the elastic deformation does not need to be increased by reducing the width of the joint of the connecting piece, the strength of the connecting piece can be ensured, the service life of the lock catch is prolonged, and meanwhile, the installation of the horizontally inserted love center type connecting piece is easy to realize.

The utility model discloses a to traditional formula hasp of violently inserting carry out the improved design, utilize the elasticity performance of connecting piece, increase horizontal atress position, can solve traditional formula hasp of violently inserting effectively and move back seam and sound scheduling problem.
