Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plywood, in particular to a spliced plywood with a compression-resistant structure. Background Art
[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into veneers, and then gluing them together with adhesive. It is usually made with an odd number of veneers, with the fibers of adjacent layers of veneers glued perpendicular to each other.
[0003] At present, in order to meet the use needs, plywood often needs to be spliced. However, when splicing plywood, most of them use glue or adopt a form similar to plug-in. By fixing plug-in columns on the sides of one set of plywood, opening slots on the sides of another set of plywood, and inserting the plug-in columns into the slots, the two sets of plywood are spliced. However, no matter splicing is done by plugging or gluing, the connection between the two sets of plywood is relatively fragile. When the front side is subjected to force, it is easy for the plug-in columns or the glue bonding to crack, affecting the normal splicing effect. For this reason, we propose a spliced plywood with a compression-resistant structure. Utility Model Content
[0004] The utility model aims to provide a spliced plywood with a compression-resistant structure to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spliced plywood with a compression-resistant structure, comprising a board body, a splicing structure is arranged on the side of the board body, the splicing structure comprises a connecting plate and a plug-in plate, the plug-in plate and the connecting plate are provided with a connecting structure for assisting splicing and improving the compression resistance, the connecting structure comprises a plug-in structure arranged in the plug-in plate and a clamping structure arranged on the connecting plate, and the plug-in structure comprises:

[0009] The L-shaped push rod can be pushed upward and retracted into the interior of the plug-in board, and the L-shaped push rod can slide in the spiral groove to rotate the sleeve. The sleeve can drive the rotating rod to rotate through the connecting piece, and the rotating rod can push the plug-in rod to move to the left through the support rod to extend out of the plug-in board and insert into the connecting plate, which can ensure stability while enhancing the strength of the joints between the two sets of plates and play a compressive resistance role.
[0010] Preferably, the connecting member includes an active plate, an active plate is fixed on the inner wall of the rotating rod, a driven plate is hinged on the surface of the sleeve, a torsion spring is fixed on the surface of the sleeve, and the end of the torsion spring away from the sleeve is fixed to the driven plate. The torsion spring can provide certain support for the driven plate. When the sleeve rotates, the sleeve rotates with the driven plate, and the driven plate can abut against the active plate to drive the rotating rod to rotate together. When the rotating rod needs to rotate alone and the sleeve cannot rotate, the rotating rod drives the active plate to rotate, and the active plate abuts against the driven plate, so that the driven plate swings at the position hinged with the sleeve, which will not affect the independent rotation of the rotating rod.
[0011] Preferably, the locking structure includes a socket, a socket is opened on the right side of the connecting plate, a resistance plate is slidably installed on the inner wall of the connecting plate, a connecting spring is fixed on the left side of the resistance plate, and the end of the connecting spring away from the resistance plate is fixed on the inner wall of the connecting plate.

When the insertion rod is inserted into the insertion hole, the insertion rod abuts on the contact plate and pushes the contact plate to move to the left, and the contact plate moves to the left with the sliding rod, and the sliding rod slides along the inclined groove, so that the L-shaped limit plate moves to the side close to the center of the connecting plate. The L-shaped limit plate can limit the plug-in plate to ensure the stability of the splicing of the two sets of plate bodies.
[0013] Preferably, a connecting plate is fixed on the right side of the plate body, and a plug-in plate is fixed on the left side of the plate body. When splicing two groups of plate bodies, the two groups of plate bodies can be spliced by inserting the plug-in plate on the left side of one group of plate bodies into the connecting plate on the right side of the other group of plate bodies.

[0016] 1. The spliced plywood with a compression-resistant structure has a splicing structure and a connecting structure. The plug-in plate on the side of one group of plate bodies is inserted into the connecting plate on the side of another group of plate bodies. After adjustment, the plug-in rod can be controlled to be inserted into the plug hole to complete the splicing of the two groups of plate bodies. While ensuring stability, the strength of the joints between the two groups of plate bodies can be enhanced to play a compression-resistant role. In addition, the plug-in plate and the connecting plate are in contact with each other, which can effectively ensure the stability of the connection and avoid fracture due to stress.
[0017] 2.

The end of the support rod 38 away from the rotating rod 35 is hinged on the surface of the plug rod 36. A connecting piece 39 is provided inside the rotating rod 35 and on the surface of the sleeve 33. When the L-shaped top rod 31 is pushed upward and retracted into the interior of the plug-in board 22, the L-shaped top rod 31 can slide in the spiral slide groove 34 to rotate the sleeve 33. The sleeve 33 can drive the rotating rod 35 to rotate through the connecting piece 39.

When the insertion rod 36 is inserted into the insertion hole 41, the insertion rod 36 abuts against the abutment plate 42 and pushes the abutment plate 42 to move to the left. The abutment plate 42 moves to the left with the sliding rod 46. The sliding rod 46 slides along the inclined groove 45, so that the L-shaped limiting plate 44 moves to the side close to the center of the connecting plate 21.

[0029] A connecting plate 21 is fixed to the right side of the plate body 1, and a plug-in plate 22 is fixed to the left side of the plate body 1. When two groups of plate bodies 1 are spliced together, the plug-in plate 22 on the left side of one group of plate bodies 1 can be inserted into the connecting plate 21 on the right side of the other group of plate bodies 1 to complete the splicing of the two groups of plate bodies 1. The connecting plate 21 is U-shaped, and the plug-in plate 22 can be inserted and engaged. A fixing plate 5 is fixed to the inner side of the connecting plate 21.

The rotating rod 35 can push the plug-in rod 36 to move to the left through the support rod 38, extend out of the plug-in board 22 and insert into the connecting plate 21. While ensuring stability, it can also enhance the strength of the joints of the two groups of plate bodies 1 to play a compressive role.
[0031] When the insertion rod 36 is inserted into the insertion hole 41, the insertion rod 36 abuts against the abutment plate 42 and pushes the abutment plate 42 to move to the left.

Under the action of the connecting spring 43, the abutment plate 42 returns to the right with the sliding rod 46, and the sliding rod 46 slides along the inclined groove 45, so that the L-shaped limit plate 44 is reset, so that the two sets of plate bodies 1 can be separated, which is convenient to use.
[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
