Description

Tenon-and-mortise limiting structure for lock catch type board

Technical Field

The utility model relates to a floor, wallboard and the decoration field of relevant panel concatenation refer in particular to a joggle limit structure who is used for hasp formula panel.

Background

The lock catch floors are widely applied to the fields of home decoration and the like due to the convenience, and can be generally divided into two categories, one category is that tenons and mortises which are matched with each other are arranged on two opposite side edges of a board, and the tenons and the mortises on the two opposite side edges of the board are utilized to be directly assembled and combined; the other type is that the connecting pieces are connected with the plates in a matching mode, and mortises matched with two sides of the connecting pieces are arranged on two opposite sides of the plates, so that the connecting pieces are used for assembling and combining the plate pieces.

By means of the interconnecting structure of the tongues and grooves on opposite sides of the sheet material, as represented by the chinese patent invention (corresponding to the united states patent of the 6,874,292 series of Floor panels with edge connectors, available from Unilin beer BV of the company) of the CN97190692.0 series of "floors made of hard sheet material units and methods of manufacturing such sheet material units" granted to the private company, the series of patent documents, which so far have twenty-more parts in common, have the same basic structure, have a connecting portion made of tongues and grooves, and are provided with integral mechanical locking means on the connecting portion, to prevent the two interconnected sheet material units from coming apart in a direction perpendicular to the relevant edges and parallel to the lower edges of the interconnected sheet material units, which has its practical utility. However, the tongue-shaped objects arranged on the side edges of the board in the structure can cause material loss, the width of the common solid wood floor is 60-125 mm, the width of the solid wood composite floor is 120-200 mm, and the width of the tongue-shaped objects is 8-12 mm, namely the width of the tongue-shaped objects accounts for 6% -13% of the width of the floor, and relatively, when the floor is paved for 100 square meters, the material used by the tongue-shaped objects is as much as 6-13 square meters, which is quite material waste.

Moreover, the structure that the tenons and the mortises on the two opposite sides of the plate are connected with each other is adopted, so that the direction limitation exists when the plates are spliced, one edge of the adjacent plate is necessarily the tenon and the other edge is the mortise, and the herringbone splicing or the cross splicing cannot be performed when the traditional long-strip-shaped plates are spliced, and the triangular plates or the hexagonal plates with a single specification cannot be manufactured to be freely spliced.

In order to solve the problems encountered by the conventional tongue and groove interconnected panel structures, the inventor of the present invention invented ZL201110431111.4(PCT/CN 2012/001714)' lock type panel connector and panel thereof, which uses a connector with a groove to connect the panels, and arranges a tongue on the side of the panel for fastening the connector at the lower side of the edge of the panel, thereby completely solving the problem of wasting material by the tongue and achieving the purpose of saving material. Meanwhile, the connecting pieces are used for connecting the boards, tenons for buckling the mortises of the connecting pieces are arranged on each side edge of the boards, and the requirement on directionality is not met during assembly, so that herringbone splicing or cross splicing can be carried out, a triangular board or a hexagonal board with a single specification can be manufactured to be matched with the connecting pieces for free splicing, and the board connecting pieces and the boards are greatly favored after being pushed out of the market.

After the intensive research of the inventor, the situation that the lock catch type plate is seriously influenced by the effect of wet expansion and dry shrinkage (or thermal expansion and cold contraction) or the change of humidity (temperature) in some extreme use environments is found, the adjacent positions of the plate are likely to have warping or large gaps and the like, and because the connecting pieces of the lock catch type plate are generally arranged at intervals, the warping and the large gaps are obvious in the parts without the connecting pieces, the flatness of the plate can be damaged when the warping occurs, the use experience of a user is negatively influenced although the warping degree is limited, and when the large gaps occur, the user can see the base surfaces and the connecting pieces paved on the plate from the gaps, dust or debris can directly fall to the base surfaces paved on the plate from the gaps, so that the problem that the cleaning is difficult is caused, and the need for improvement is really needed.

Fig. 3 to 6 are schematic views showing the assembly process of a plate 10B and a connecting member 20B according to a second embodiment of the present invention, wherein fig. 3 shows that the left plate 10B is assembled with the connecting member 20B, and the right plate 10B is initially assembled as shown in fig. 3 by first abutting the tenon 12B of the right plate 10B to the opening of the mortise 22B on the right side of the connecting member 20B, allowing the nose 122B of the tenon 12B to touch the abutting surface 262B of the first protrusion 26B, or allowing the outer end surface of the position-limiting flange 13B to touch the side of the upper block 11B of the adjacent plate 10B, or allowing the latch sidewall 240B of the connecting member 20B to touch the tenon 12B, and then pressing down the right plate 10B, wherein during the pressing down of the right plate 10B in fig. 3 to 4, the opening of the mortise 22B of the connecting member 20B is spread, and allowing the tenon 12B of the plate 10B to be inserted into the mortise 22B (the state that the opening of the mortise 22B is spread is not shown in fig. 4 and 5, therefore, the material of the right lower part of the tenon 12B of the board 10B and the right lower part of the mortise 22B of the connecting member 20B partially overlaps, which is the range of the opening of the mortise 22B to be expanded, when the opening of the mortise 22B is expanded to be large enough, the nose part 122B of the tenon 12B is staggered with the abutting surface 262B of the first protrusion 26B, and at the same time, the outer end surface of the position-limiting flange 13B is also staggered with the side edge of the upper edge block 11B of the adjacent board 10B, and then the tenon 12B is moved to the position shown in fig. 6 by the action of the contact inclined surface between the tenon 12B and the mortise 22B and the deformation restoring force of the connecting member 20B (the technology of buckling the tenon 12B of the board 10B and the mortise 22B of the connecting member 20B is described in detail in the previous patent application of the present invention, and therefore not repeated), when the right sheet material 10B is moved from the position shown in fig. 5 to the position shown in fig. 6, the position restricting flange 13B of the right sheet material 10B is also fitted into the position restricting groove 14B of the left sheet material 10B.

When the tenon 12B of the plate 10B is assembled into the mortise 22B of the connecting piece 20B, as shown in FIGS. 3 to 6, the tenon is installed in a manner that one side of the right plate 10B, which is provided with the limit flange 13B, is embedded with the limit groove 14B of the left plate 10B, or in a manner that one side of the right plate 10B, which is provided with the limit groove 14B, is embedded with the limit flange 13B of the left plate 10B, as shown in FIGS. 7 to 9, i.e. the installation in a manner that the limit flange 13B is embedded into the limit groove 14B or the installation in a manner that the limit groove 14B is embedded into the limit flange 13B is not required during actual installation, so that the operation is flexible; in addition, it can be seen from the assembly process schematic diagrams of fig. 4 to 6 and fig. 7 to 9 that the limiting mechanism (the limiting flange 13B and the corresponding limiting groove 14B) of the present invention does not affect the straight-falling installation of the plate.
