Detailed Description
The following is a specific embodiment of the present invention, and the technical solution of the present invention is further described with reference to the accompanying drawings, but the present invention is not limited to these examples.
The words "vertical", "horizontal", "up", "down", "left", "right", "front" and "rear" in this embodiment refer to directions in the drawings, and thus, according to the directions illustrated in fig. 1, sides of the drawing parallel to the connecting sides of the front side and the upper top surface of the wood-plastic panel 100 are referred to as "long", and sides of the connecting sides parallel to the front side and the right side of the wood-plastic panel 100 are referred to as "high".
A T-shaped self-locking type combined wood-plastic plate is shown in figure 1: the wood-plastic composite board comprises a plurality of wood-plastic boards 100 connected through a self-locking structure, wherein the wood-plastic boards 100 can be one of PVC wood-plastic boards, PE wood-plastic boards or PP wood-plastic boards.
The self-locking structure includes an insertion portion 110 and a groove portion 120 disposed on an end surface of the wood-plastic panel 100, where the insertion portion 110 and the groove portion 120 may be disposed on the same end surface of the wood-plastic panel 100 or on different end surfaces, so long as the insertion portion 110 of one wood-plastic panel 100 can be inserted into the groove portion 120 of another wood-plastic panel 100, so that different connection methods may be provided between the wood-plastic panels 100, for example: the right side of one wood-plastic panel 100 is provided with an insertion part 110, the front side of the other wood-plastic panel 100 is provided with a groove part 120, and the insertion part 110 is inserted into the groove part 120 to vertically connect the two wood-plastic panels 100 to form an L-shaped or T-shaped structure; similarly, the wood-plastic boards 100 can be horizontally arranged and connected end to end through other different arrangement modes, so that floors or wallboards with different areas and shapes can be matched, or the purpose of designing different lines can be achieved, and the practicability is high.
As shown in fig. 2, the groove portion 120 includes a notch 121 and an inner cavity 122 having a height greater than the height of the notch 121. The insertion portion 110 includes a shaft body 111 axially parallel to the end face of the wood plastic panel 100, and a movable locking member 112 disposed on the shaft body 111, wherein the movable locking member 112 can rotate together with the shaft body 111 in a vertical plane. However, since the movable locking member 112 and the shaft body 111 need to be connected to both sides of the wood-plastic panel 100 and also need to be rotated, the fixing frames 113 are provided at both sides (front side and rear side in fig. 1) perpendicular to the axial direction of the shaft body 111, and the shaft body 111 is installed between the fixing frames 113, thereby ensuring that the shaft body 111 and the movable locking member 112 can be kept rotated when being connected to the sides of the wood-plastic panel 100.
When the movable locking member 112 is perpendicular to the end face of the wood-plastic plate 100, as shown in fig. 3 and 4, the length of the movable locking member 112 is greater than half the height of the notch 121, the movable locking member 112 comprises a first locking member 112a fixedly connected with the shaft body 111 and a second locking member 112b connected with the shaft body 111 through a gear structure, the gear structure comprises a central wheel 131 sleeved on the shaft body 111, a plurality of driving wheels 132 meshed with the central wheel 131 and a gear ring 133 meshed with the driving wheels 132, the second locking member 112b is connected with the gear ring 133, so that after the movable locking member 112 of one wood-plastic plate 100 is inserted into the groove 120 of the other wood-plastic plate 100 at a position perpendicular to the end face of the wood-plastic plate 100, the first locking member 112a and the second locking member 112b rotate in different directions in the inner cavity 122 for an alpha angle to form a Y-shaped or T-shaped or arrow-shaped structure, and the sum of the decomposition lengths of the lengths in the vertical direction is greater than the height of the notch 121, thereby the stop inserting part 110 is separated from the groove 120,0 DEG < alpha < 180 deg. The principle that the rotation directions of the first locking member 112a and the second locking member 112b are different is as follows: when the shaft body 111 is rotated clockwise by an external force, the first locking member 112a and the central wheel 131 fixedly connected with the shaft body 111 are also rotated clockwise, and the central wheel 131 drives the driving wheel 132 to rotate counterclockwise, and simultaneously, all the driving wheels 132 drive the same gear ring 133 and the second locking member 112b connected with the gear ring 133 to rotate counterclockwise.
Wherein, alpha is optimally 90 degrees, at this time, the movable locking member 112 forms a T-shaped structure, and is perpendicular to the connection direction of the insertion portion 110 and the groove portion 120, and the self-locking effect is optimal.
Because the rotation of the movable locking member 112 requires external force driving, a pulling piece for pulling the shaft body 111 and rotating the movable locking member 112 is arranged on the exposed end surface of the shaft body 111, so that the effect of rotating the movable locking member 112 arranged in the wood-plastic panel 100 can be achieved, the rotating state of the movable locking member 112 can be observed through the pulling piece, and the self-locking state can be maintained through the fixed pulling piece. Meanwhile, in order to prevent the pulling piece from affecting the appearance of the combined wood-plastic panel 100, the pulling piece may be patterned to be used as a decorative pattern for decorating the wood-plastic panel 100.
The external force driving mode may be that screw holes are formed in the exposed end face of the shaft body 111, an externally added screw is inserted into the screw holes, the shaft body 111 and the movable locking piece 112 are driven to rotate and self-lock, and then the screw is pulled out.
In order to further improve the practicability, the wood-plastic panel 100 can be filled with sound-absorbing cotton to obtain good noise reduction and insulation effects.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
