Description

TECHNICAL FIELD

The disclosure relates to the technical field of plates, in particular to a herringbone locking plate unit and a splicing plate.

BACKGROUND ART

Currently, there are two ways to assemble lock series of herringbone floorings or wallboards.

The first one involves division of A and B plates, and A and B products are assembled alternately in two directions. In production of this series, half of reverse grooves need to be processed twice, in which after longitudinal processing is completed, direction adjustment is performed for transverse production. In packaging, one piece of A plate and one piece of B plate need to be packed. In installation by a user, a piece of A plate and a piece of B plate also need to be alternately installed in a herringbone pattern, with a complicated preparation process, installation process and transportation process, which greatly increases use cost.

For the second one, in production of a herringbone product, it is necessary to use a jumping cutter to process two ends of edges of a longitudinal groove of a flooring, but this product is with a large jumping position error, a small tension index, and low production efficiency.

Further, existing herringbone splicing plates need to be clamped and installed up and down in locking, which brings much inconvenience to the installation process.

The third clamping structure includes a first locking tongue 64 protruding in the horizontal direction, a first locking groove 63 opened downwards, a second locking groove 61 opened downwards, and a second locking tongue 62 protruding downwards. “Downwards” refers to a direction perpendicular to the horizontal direction in the drawing and facing a laying surface. The first locking tongue, the first locking groove, the second locking tongue and the second locking groove can be sequentially arranged from top to bottom. In other embodiments, they can be arranged from bottom to top.

As shown in FIG. 13, the schematic view of the plates before and after clamping is shown from top to bottom. The black solid arrow refers to a direction of the force applied. The clamping directions between the second clamping structure 5 and the third clamping structure 6, and between the first clamping structure 4 and the third clamping structure 6 are all horizontal force inlaid, and then the locking and clamping are carried out.

Optionally, a pocket 65 is provided above the first locking tongue, a side face of the second locking groove proximate to the first locking tongue is an inclined side face and a side face of the second locking groove proximate to the second locking tongue can also be an inclined side face, which facilitates sliding in and fastening.

The first clamping structure 4 is further provided with an avoidance step 41 horizontally defined and a third locking groove 42, and the avoidance step 41 is configured for avoiding the first locking tongue of the third clamping structure, reserving a space for the first locking tongue. The avoidance step 41, the third locking groove 42 and the first locking hook 43 can be sequentially arranged from top to bottom. In other embodiments, they can be arranged from bottom to top. A schematic view of matching of the third clamping structure and the first clamping structure can be referred to FIG. 6.
