Description

Technical Field

[0001] This utility model relates to the field of composite door panels, specifically a low-formaldehyde wood-plastic composite door panel. Background Technology

[0002] Composite door panels are doors composed of two or more different materials. Common composite door materials include solid wood composite doors and molded door panels. The "composite door panel structure" disclosed in application number "CN215408226U" is an increasingly mature technology. It utilizes environmentally friendly materials for both the main body of the door panel and the rectangular frame, primarily aluminum alloy profiles and sintered stone. The aluminum alloy rectangular frame and sintered stone have high bending strength, making them not only durable but also heat-resistant, corrosion-resistant, healthy, environmentally friendly, formaldehyde-free, stain-resistant, and scratch-resistant, effectively extending the service life of the composite door panel structure. By adding aluminum alloy rectangular frames around the main body of the door panel, problems such as deformation and twisting common in existing door panels are avoided, further extending the service life of the composite door panel structure and improving its stability. The handle profiles are also integrated into the rectangular frame. "The frame eliminates the need for additional door handles, saving materials, reducing costs, and improving the user experience." However, this composite door panel has the following drawbacks: While the aluminum alloy profiles and slab structure do reduce formaldehyde content and improve safety, the aluminum alloy structure increases weight, affecting transport efficiency and increasing costs, hindering widespread adoption. Therefore, it is necessary to provide a composite door panel that reduces formaldehyde content while controlling costs and weight, making it easier to promote. Furthermore, the simple overall structure of this composite door panel results in insufficient compressive strength. Therefore, it is necessary to provide a composite door panel that significantly enhances its strength and extends its lifespan. Utility Model Content

[0003] This utility model provides a low-formaldehyde wood-plastic composite door panel, aiming to solve the problems of existing composite door panels having insufficient formaldehyde content, as well as increasing weight and cost.

[0004] To achieve the above objectives, this utility model provides a low-formaldehyde wood-plastic composite door panel, including a door panel assembly;

[0005] The door panel assembly includes a first outer door panel and a second outer door panel. The interior of the first outer door panel and the second outer door panel are each equipped with a plurality of composite reinforcing plates. The upper ends of the plurality of composite reinforcing plates are respectively provided with a plurality of first filling grooves and second filling grooves. The interiors of the plurality of first filling grooves and second filling grooves are respectively inserted with a first reinforcing strip and a second reinforcing strip.

[0006] As a preferred embodiment of this utility model, the interior of the first outer door panel is provided with several reinforcing ribs.

[0007] As a preferred embodiment of this utility model, two insertion holes are provided on both sides of the opposite surfaces of the first outer door panel and the second outer door panel, and insert ribs are inserted into the interior of both insertion holes.

[0008] As a preferred embodiment of this utility model, the inner walls of the first outer door panel and the second outer door panel are symmetrically provided with several strip grooves at equal intervals on both sides, and several positioning strips are fixedly connected to both sides of the composite reinforcing plates, and the positioning strips are all engaged inside the strip grooves.

[0009] As a preferred embodiment of this utility model, the first outer door panel, the second outer door panel, and the composite reinforcing plate are all made of resin.

[0010] In a preferred embodiment of this utility model, the reinforcing rib is made of stainless steel.

[0011] As a preferred embodiment of this utility model, both the first reinforcing strip and the second reinforcing strip are made of flame-retardant material.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When using composite door panels, the first outer door panel, the second outer door panel, and several composite reinforcing plates made of resin can not only reduce the weight and control the cost, but also greatly reduce the formaldehyde content, thus improving the safety of use. The first and second reinforcing strips made of flame-retardant material can prevent the composite door panel from burning when heated. Compared with the composite door panel in the prior art "a composite door panel structure", this utility model can reduce the formaldehyde content and reduce the weight to control the cost through the cooperation of the above structures, thereby extending the safety of use of the composite door panel and facilitating its widespread use.

[0014] 2. When using composite door panels, the overall compressive strength can be initially enhanced by several composite reinforcing plates in conjunction with the first and second outer door panels. At the same time, several first reinforcing strips in conjunction with the second reinforcing strips can further enhance the overall strength of the composite door panel. The first and second filling grooves with several triangular structures opened at the upper end of several composite reinforcing plates can significantly enhance the structural strength of the composite reinforcing plates. Compared with the composite door panel in the prior art "a composite door panel structure", this utility model can significantly enhance the strength of the composite door panel through the above-mentioned structure cooperation, thereby extending the service life of the composite door panel.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1-5 This utility model provides a low-formaldehyde wood-plastic composite door panel, including a door panel assembly 100;

[0024] The door panel assembly 100 includes a first outer door panel 101 and a second outer door panel 102. Both the first outer door panel 101 and the second outer door panel 102 have several composite reinforcing plates 103 installed inside. The upper ends of the composite reinforcing plates 103 are respectively provided with several first filling grooves 104 and second filling grooves 105. The first filling grooves 104 and the second filling grooves 105 are respectively inserted with first reinforcing strips 106 and second reinforcing strips 107.

[0025] In one specific embodiment, the resin-material first outer door panel 101 and second outer door panel 102 in the door panel assembly 100 not only significantly reduce the formaldehyde content of the composite door panel, but also control the cost and reduce the weight, thus facilitating widespread use and improving ease of use. Furthermore, the combined structure significantly enhances the overall strength of the composite door panel, thereby extending its service life. The first outer door panel 101, combined with the second outer door panel 102 and several composite reinforcing plates 103, significantly enhances the strength of the composite door panel itself. The several triangular first filling grooves 104 and second filling grooves 105 on the upper end of the composite reinforcing plates 103 further enhance their compressive strength. Finally, the first reinforcing strip 106 and second reinforcing strip 107 improve the deformation resistance of the composite door panel. The combined structure not only reduces formaldehyde content but also reduces weight, thereby improving the safety of the composite door panel.

[0026] Please see Figure 2 The first outer door panel 101 has several reinforcing ribs 111 embedded inside.

[0027] In one specific embodiment, the reinforcing rib 111 is embedded inside the first outer door panel 101 and the second outer door panel 102 to help enhance the overall structural strength of both and extend their service life.

[0028] Please see Figure 2 and Figure 3 Two insertion holes 121 are provided on both sides of the opposite surfaces of the first outer door panel 101 and the second outer door panel 102, and insertion rods 122 are inserted into the interior of the two insertion holes 121.

[0029] In one specific embodiment, the insert 122 is inserted into the insertion hole 121, which can improve the connection strength and stability between the first outer door panel 101 and the second outer door panel 102, thereby improving the overall structural integrity of the composite door panel.

[0030] Please see Figure 3 The inner walls of the first outer door panel 101 and the second outer door panel 102 are symmetrically provided with several strip grooves 131 at equal intervals. Several positioning strips 132 are fixedly connected to both sides of several composite reinforcing plates 103, and the positioning strips 132 are snapped into the inside of the strip grooves 131.

[0031] In one specific embodiment, several positioning strips 132 are snapped into the inside of the strip groove 131, thereby enhancing the installation stability between the composite reinforcing plate 103, the first outer door panel 101, and the second outer door panel 102.

[0032] Please see Figure 2 and Figure 3The first outer door panel 101, the second outer door panel 102, and the composite reinforcing plate 103 are all made of resin.

[0033] In one specific embodiment, the first outer door panel 101, the second outer door panel 102, and the composite reinforcing panel 103 made of resin can significantly reduce the formaldehyde content of the above structure and improve the safety of the composite door panel.

[0034] Please see Figure 2 The reinforcing rib 111 is made of stainless steel.

[0035] In one specific embodiment, the stainless steel reinforcing rib 111 can prevent rust and enhance the structural strength of the first outer door panel 101 and the second outer door panel 102 from the inside, thus extending the service life of the composite door panel.

[0036] Please see Figure 4 and Figure 5 Both the first reinforcing strip 106 and the second reinforcing strip 107 are made of flame-retardant material.

[0037] In one specific embodiment, the first reinforcing strip 106 and the second reinforcing strip 107, made of flame-retardant material, can prevent combustion due to excessive temperature, thereby helping to enhance the overall safety of the composite door panel.

[0038] Working principle: In use, the first outer door panel 101, together with the second outer door panel 102 and several composite reinforcing plates 103, can initially enhance the strength of the composite door panel itself. The first filling groove 104 and the second filling groove 105 with several triangular structures opened at the upper end of the composite reinforcing plate 103 can further enhance its compressive strength. Finally, the first reinforcing strip 106 and the second reinforcing strip 107 can improve the deformation resistance of the composite door panel. The above structures work together to not only reduce the formaldehyde content, but also reduce the weight. The resin material of the first outer door panel 101 and the second outer door panel 102 can significantly reduce the formaldehyde content. The first reinforcing strip 106 and the second reinforcing strip 107 made of flame retardant material can improve the safety of the composite door panel, thus facilitating the promotion and use of the composite door panel.
