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 ratchet 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.
120 may be disposed on the same end surface of the wood-plastic panel 100 or may be disposed 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.
The groove part 120 comprises a notch 121 and an inner cavity 122 with the height larger than that of the notch 121, and the insertion part 110 comprises a shaft body 111 axially parallel to the end surface of the wood-plastic panel 100 and a movable locking piece 112 arranged on the shaft body 111, wherein the movable locking piece 112 can rotate around the shaft body 111 or 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.
In the present embodiment, when the length direction of the movable locking member 112 is perpendicular to the end surface of the wood plastic panel 100, the height of the movable locking member should be not greater than the height of the notch 121, so that the insertion portion 110 can be smoothly inserted into the groove portion 120 in this state; the length of the movable locking member 112 should be greater than the height of the notch 121, so that the movable locking member 112 can be slightly rotated by an angle alpha (0 DEG < alpha < 180 DEG) around the shaft body 111 or together with the shaft body 111 in the inner cavity 122, and then the length of the movable locking member 112 can be decomposed to a greater height in the vertical direction than the height of the notch 121, so that the movable locking member cannot be separated from the notch 121.
Wherein, alpha is optimally 90 degrees, at this time, the movable locking member 112 is perpendicular to the connection direction of the insertion portion 110 and the groove portion 120, and the self-locking effect is optimal.
In addition, the rotation of the movable locking member 112 requires external force to drive, so that the movable locking member 112 is fixedly connected with the shaft body 111, and a shifting piece for shifting the shaft body 111 and rotating the movable locking member 112 are arranged on the exposed end surface of the shaft body 111
The pointer indicating the rotation angle can achieve the effect of rotating the movable locking member 112 arranged in the wood-plastic panel 100, and can observe the rotation state. Meanwhile, in order to prevent the appearance of the combined wood-plastic panel 100 from being affected by the pulling piece and the pointer, the pulling piece and the pointer may be patterned so as to be used for decorating the patterns of the wood-plastic panel 100.
After the self-locking state is formed, it should be noted that the movable locking member 112 is prevented from being reversely rotated in the inner cavity 122 to release the self-locking state, and thus a ratchet structure for stopping the reverse rotation of the movable locking member 112 is required to be provided, as shown in fig. 2, which includes ratchet teeth 131 provided at the circular arc end portion of the movable locking member 112 and pawls 132 provided at the groove portion 120, wherein the pawls 132 are rotated only in a direction opposite to the rotation direction of the movable locking member 112 by means of the pawl stoppers 133. That is, as shown in the orientation of fig. 2, when movable locking member 112 is self-locking, it is necessary to rotate counterclockwise, pawl 132 only rotates clockwise, so that when movable locking member 112 rotates counterclockwise, pawl 132 is shifted by ratchet teeth 131 slightly in a clockwise direction to allow movable locking member 112 to rotate therethrough; when the movable locking member 112 has a clockwise rotation tendency, the pawl 132 is engaged with the gap of the ratchet teeth 131, so as to prevent the movable locking member 112 from rotating clockwise to release the self-locking state. The pawl stopper 133 may be a supporting frame provided on the right side of the pawl 132, where the pawl 132 is erected on the supporting frame by its own weight and is not connected with the supporting frame; the pawl stop 133 may also be other components such as a spring.
Further, in order to enhance the ratchet catching effect thereof, ratchet teeth 131 may be provided on both end surfaces of the movable lock member 112, and a plurality of pawls 132 and pawl stoppers 133 may be provided on the groove portion 120.
In addition, in order to enable the movable locking member 112 to smoothly rotate in the inner cavity 122, the inner cavity 122 is generally configured to be an inner cavity having a diameter not smaller than that of the movable locking member 112 and a circular cross section, and although the narrower notch 121 and the wider inner cavity 122 can achieve the effect of preventing the insertion portion 110 from being separated, in order to prevent the movable locking member 112 from rotating 180 ° but returning to the original insertion state to release the self-locking effect, and in order to further enhance the stopping effect of the groove portion 120, as shown in fig. 2, the groove portion 120 is further provided with a stopper 123 stopping the rotation of the movable locking member 112 after rotating by an angle α.
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.
