[0035] As Figures 1 to 5 Indicated, the composite door of the utility model embodiment includes skeleton 100 and two door panels 200, skeleton 100 has oppositely arranged first side 110 and second side 120;One of the two door panels 200 is connected to the first side 110 of the skeleton 100, and the other is connected to the second side 120 of the skeleton 100;Door panel 200 is provided with a plurality of clamping pieces 210, and skeleton 100 is provided with clamping groove 130;A plurality of clamping pieces 210 are arranged along the extension direction of clamping groove 130 and are embedded in clamping groove 130, so that door panel 200 is fixed to skeleton 100;The composite door further includes a fixing piece;Clamping piece 210 includes base 211 and adjusting part 212, base 211 is fixed to door panel 200;Fixed groove 2111 is arranged on base 211, adjusting part 212 is arranged in fixed groove 2111 and is fixed in fixed groove 2111 by fixing piece;Fixed groove 2111 extends along the width direction of clamping groove 130.

[0036] The door plate 200 is fixed on the framework 100 by embedding the engaging member 210 into the engaging groove 130; in operation, the door plate 200 is only needed to be pressed on the corresponding position on the framework 100, so that the door plate 200 is fixed on the framework 100, without the need of cold pressing process, and the door plate 200 is convenient to disassemble and assemble, and the production efficiency is improved; the engaging member 210 is arranged on the door plate 200, without the need of machining holes and grooves on the door plate 200, so that the structural strength of the door plate 200 is avoided from being affected by machining holes and grooves, and the risk of force damage of the door plate 200 is reduced; when the door plate 200 is replaced, only the engaging member 210 needs to be installed on the new door plate 200; in assembly, the adjusting part 212 slides in the fixing groove, so that the relative position between the adjusting part 212 and the door plate 200 is adjusted, the adjusting part 212 corresponds to the engaging groove 130, and then the adjusting part 212 can be embedded into the engaging groove 130; the plurality of engaging members 210 are arranged at intervals along the extension direction of the engaging groove 130, each engaging member 210 can independently adapt to the small range deviation of the engaging groove 130 at the corresponding position, the engaging member 210 is conveniently aligned and embedded into the engaging groove 130, and the assembly difficulty is reduced.

[0037] The composite door in the prior art is cured by a cold pressing process after being bonded, and the composite door in the embodiment of the utility model does not need glue and a cold pressing process, the door plate 200 can be installed on the framework 100 by simple embedding, without the need of additional installation tools, and the operation is simple and convenient; the door plate 200 can be used as a veneer of the composite door, the engaging member 210 and the engaging groove 130 can be directly buckled to complete the installation of the door plate 200, or the engaging member 210 can be directly separated from the engaging groove 130 to complete the separation of the door plate 200 and the framework 100, so that the door plate 200 of different materials, different patterns or different shapes is conveniently replaced.

[0038] The plurality of clamping pieces 210 are arranged at intervals along the extension direction of the clamping groove 130. If the plurality of clamping pieces 210 are replaced by clamping strips matched with the clamping groove 130, longer clamping strips need to be arranged. An integral clamping strip must have very high straightness, parallelism and dimensional accuracy. If the clamping strip is slightly curved or twisted, the clamping strip and the clamping groove 130 cannot be matched. The plurality of clamping pieces 210 arranged at intervals are arranged along the extension direction of the clamping groove 130. Not only the material cost can be saved, but also each clamping piece 210 can independently adapt to the small range deviation of the clamping groove 130 at the corresponding position. The gap between the two adjacent clamping pieces 210 provides necessary elastic space and adjustment allowance, greatly reduces the requirement for manufacturing precision, and improves the yield and assembly efficiency. At the same time, the material (especially plastic and wood) will expand and shrink with the change of temperature and humidity. The gap between the two adjacent clamping pieces 210 can provide sufficient space for the thermal expansion and contraction of the clamping piece 210 in the length direction, avoid stress accumulation, and improve the stability of the composite door under environmental changes. In addition, if a clamping piece 210 is damaged, the other clamping pieces 210 can usually provide sufficient connection strength, thereby improving the robustness and maintainability of the connection.

[0039] As shown in Figures 1 to 2 In some embodiments, the clamping groove 130 is arranged on the framework 100, and the clamping piece 210 is arranged on the side of the door plate 200 facing the framework 100. The door plate 200 is fixed on the framework 100 through the matching of the clamping piece 210 and the clamping groove 130. The clamping piece 210 is arranged on the door plate 200, and there is no need to process holes and grooves on the door plate 200, which avoids affecting the structural strength of the door plate 200 due to processing holes and grooves, and reduces the risk of force damage of the door plate 200. When replacing the door plate 200, only the clamping piece 210 needs to be installed on the new door plate 200.

By moving the adjusting part 212 within the fixing groove 2111, the user can easily adjust the relative position of the engaging member 210 and the engaging groove 130 to compensate for minor errors in the manufacturing process. This not only improves the installation accuracy of the composite door but also enhances its adaptability to different environments and usage conditions. Generally, the base 211 is a plate, which can be fixed to the door panel 200 by threaded connection or adhesive. The fixing member is a screw, and the adjusting part 212 has an opening through which the fixing member passes to connect with the base 211, thereby fixing the adjusting part 212 to the base 211.
