[0033] In the description of the present utility model, it should be understood that the terms "upper", "lower", "inside", "outside", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the utility model product is usually placed when in use, or are directions or positional relationships that are usually understood by those skilled in the art. These directions or positional relationships are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present utility model.

[0034] In addition, the terms "first", "second", etc. are only used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms such as "setting" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection: it can be a mechanical connection or an electrical connection: it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] As attached Figure 1 As shown, the two ends of the prior art wood plastic wallboard have a male connection part a and a female connection part b respectively, and the prior art uses a bidirectional slotted connection member to complete the connection between the two wood plastic wallboards. However, under this existing installation method, there are problems: the wood plastic wallboard is easily expanded by heat, and the gap between the wood plastic wallboards is smaller than the expansion length, which easily leads to the problem of "arching" between the two wood plastic wallboards. If the expansion joint reserved between the two wood plastic wallboards is too large, it will cause the problem of poor aesthetics.

[0037] The present embodiment provides a wood-plastic wallboard connecting member, which is used to overcome the problem of "arching" caused by thermal expansion between two wood-plastic wallboards 11 while ensuring aesthetics. Figures 2 to 8 As shown, the specific structure is as follows:

[0038] The connecting member includes a fixed keel 1 arranged along the width direction of the wood-plastic wallboard 11, a mounting groove 2 arranged on the fixed keel 1, a first connecting member slidably connected to the mounting groove 2 and connected to the male connecting part a, a second connecting member slidably connected to the mounting groove 2 and connected to the female connecting part b, and an elastic component 3 arranged between the first connecting member and the second connecting member.

[0039] In this embodiment, the fixed keel 1 includes a main body block 101 provided with the mounting groove 2, a mounting base plate 102 provided at the lower end of the main body block 101, and mounting screw holes 103 provided on both sides of the mounting base plate 102. The mounting screw holes 103 are countersunk screw holes, and the entire fixed keel 1 is mounted on the wall by existing screws or studs.

[0040] In this embodiment, the first connecting member and the second connecting member both have an active slot 601 and an active bottom plate 602 slidably connected to the slot body 201, and the width of the slot body 201 is greater than the sum of the widths of the two active bottom plates 602. The mounting slot 2 includes a slot body 201, and two pressing plates 202 disposed on two opposite side walls of the slot body 201 at the slot opening, and the ends of the pressing plates 202 are provided with chamfers 203.

[0041] It is worth noting that "the width of the trough 201 is greater than the sum of the widths of the two movable bottom plates 602" means that after the two movable bottom plates 602 are installed in the trough 201, there is still a certain gap between the two movable bottom plates 602, and the width of the gap is 3-30 mm, which is the width of the reserved expansion joint commonly used in this field. However, the device is arranged between the first connecting member and the second connecting member, hidden under the wood-plastic wallboard 11, which ensures that there is no obvious gap on the surface of the connection between the two wood-plastic wallboards 11, and after the wood-plastic wallboard 11 is heated and expanded, the distance between the two connecting members is sufficient to accommodate the gap caused by the expansion of the wood-plastic wallboard 11, avoiding the problem of "arching". The pressing plate 202 is mainly used to improve the stability of the movable bottom plate 602 in the trough 201, and the chamfer 203 is mainly set to reduce the difficulty of inserting the movable bottom plate 602 into the trough 201.

[0042] In this embodiment, the elastic component 3 includes a fixing groove 301 respectively arranged on two opposite sides of the first connecting member and the second connecting member, two mounting plates 302 respectively arranged in the two fixing grooves 301, and a support spring 303 connected to the two mounting plates 302 at both ends. After the lower reinforcement member 4 and the upper reinforcement member 5 described below are installed, the support spring 303 is compressed, thereby providing sufficient support to the connecting members on both sides, respectively, to ensure the installation stability between the two connecting members. When the wood plastic wallboard 11 expands due to heat, the two wood plastic wallboards 11 squeeze the two connecting members respectively, the support spring 303 is further compressed, and the distance between the two connecting members is shortened, providing space for the expansion of the wood plastic wallboard 11, avoiding the problem of "arching".

[0043] In this embodiment, the connecting member also includes a lower reinforcement member 4 arranged between the first connecting member and the second connecting member and located at the lower end of the elastic component 3, and the lower reinforcement member includes two first fixing holes 401 respectively arranged on the first connecting member and the second connecting member, a first connecting screw 402 with two ends passing through the two fixing holes 401 respectively, two first limiting nuts 403 respectively arranged at both ends of the first connecting screw 402 and threadedly connected to the first connecting screw 402, and a first groove 404 respectively arranged on the first connecting member and the second connecting member and connected to the first fixing hole 401 for embedding the first limiting nut 403.

[0044] The purpose of setting the lower reinforcement member 4 in this embodiment is to ensure the connection stability of the lower ends of the two connecting members, and to restrict the maximum distance between the two connecting members.

[0045] In this embodiment, the connecting member also includes an upper reinforcement member 5 arranged between the first connecting member and the second connecting member and located at the upper end of the elastic component 3, and the upper reinforcement member includes two second fixing holes 501 respectively arranged on the first connecting member and the second connecting member, a countersunk hole 502 arranged on the side of the first connecting member and connected to the second fixing hole 501, a panel 503 arranged in the countersunk hole 502, a second connecting screw 504 arranged at the center of the panel 503 and passing through the two second fixing holes 501 in sequence, a second limiting nut 505 arranged on the side of the second connecting screw 504 away from the panel 503 and threadedly connected to the second connecting screw 504, and a second groove 506 arranged on the second connecting member and connected to the second fixing hole 501 for embedding the second limiting nut 505.

[0046] The purpose of setting the upper reinforcement member 5 in this embodiment is to ensure the connection stability of the upper ends of the two connecting members, and to restrict the maximum distance between the two connecting members. The structure of the upper reinforcement member 5 is not completely the same as that of the lower reinforcement member 4, that is, the purpose of setting the countersunk hole 502 and the panel 503 is to ensure that the panel 503 is lower than or flush with the bottom surface of the movable slot 601 to avoid affecting the installation of the male connection part a.

[0047] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
