[0025] In the description of this utility model, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] The following is in conjunction with the appendix Figure 1-10 The present invention will be further described below.

[0027] To address the problems existing in the background technology, this application proposes the following technical solution: a spliced ​​door body, including a first door frame 1 and a second door frame 2, the first door frame 1 and the second door frame 2 are combined to form a U-shaped structure, both the first door frame 1 and the second door frame 2 are provided with sliding openings 13, and multiple sets of splicing plates 8 are slidably connected in the sliding openings 13, a decorative plate 3 is slidably inserted into the outside of the first door frame 1, the decorative plate 3 is provided with a decorative coating, and a locking component is provided on the outside of the first door frame 1 to fix the decorative plate 3; the first door frame 1 and the second door frame 2 are made of high-strength aluminum alloy profiles, which are precision cut and anodized, not only with excellent corrosion resistance, but also the U-shaped structure formed after combination, the setting of the sliding openings 13 breaks through the limitations of traditional door body fixed panels, the multiple sets of splicing plates 8 can flexibly select materials and colors (such as glass, solid wood, metal, etc.) according to design requirements, and are quickly installed through the sliding openings 13, which greatly facilitates later maintenance and style adjustment.

[0028] The decorative coating on the surface of decorative panel 3 uses environmentally friendly fluorocarbon paint, which is UV resistant and weather resistant, and supports customized pattern printing to meet the needs of different decoration styles. The pre-layout of the locking components ensures that decorative panel 3 is stable and reliable after installation, preventing it from falling off due to vibration or external force.

[0029] In a further design, the exterior of the first door frame 1 is provided with a first sliding groove 9, and the exterior of the decorative panel 3 is fixedly connected with a first sliding strip 10. The first sliding strip 10 is slidably connected in the first sliding groove 9. The length of the first sliding groove 9 is less than the length of the first door frame 1. The interface between the first sliding groove 9 and the first sliding strip 10 is a T-shaped structure. The matching design of the T-shaped groove and the sliding strip is the core of achieving rapid installation and precise positioning of the decorative panel 3. The first sliding groove 9 is manufactured using an extrusion molding process, with an inner wall roughness Ra≤1.6μm. It forms a precision sliding pair with the T-shaped cross-section of the first sliding strip 10, with the gap controlled within ±0.2mm, ensuring smooth sliding of the decorative panel 3 without wobbling. The design that the length of the groove is less than the length of the door frame not only limits the sliding stroke of the decorative panel 3, preventing it from detaching from the door frame, but also reserves installation space for the locking components. Furthermore, the T-shaped structure has excellent mechanical properties.

[0030] In actual installation, the decorative panel 3 is positioned by pushing it into the first groove 9 along the first sliding strip 10, without the need for tools. This design is particularly suitable for installation at heights or in confined spaces, reducing the labor intensity and safety risks for operators. Furthermore, the T-shaped structure provides excellent sealing, and combined with the silicone sealing strips on the edges of the decorative panel 3, it effectively prevents dust and rainwater from entering, thus improving the door's sound insulation performance.

[0031] In this technical solution, the decorative panel 3 has a second sliding groove 11 on its exterior, and a base plate 4 on its exterior. A second sliding strip 12 is fixedly connected to the exterior of the base plate 4, and the second sliding strip 12 is slidably connected in the second sliding groove 11. The addition of the second sliding groove 11 and the second sliding strip 12 constructs a secondary positioning system between the decorative panel 3 and the base plate 4, further enhancing the stability and decorative effect of the door. The base plate 4 is made of high-density fiberboard (HDF) with a moisture-proof surface treatment, and can be adapted to various decorative styles of panels (such as wood grain, stone grain, metal panels, etc.). Operators can push the base plate 4 with one hand to complete the installation, saving effort and making it convenient. This layered structural design allows the decorative panel 3 and the base plate 4 to be replaced independently or combined. For example, while keeping the decorative panel 3 unchanged, the texture and color of the door can be quickly changed by replacing the base plate 4, providing more possibilities for interior design.

[0032] In addition, the depth of the second slide groove 11 and the height of the second slide bar 12 have been optimized (15mm depth and 12mm height). While ensuring smooth sliding, they form a 10mm overlapping protective edge, effectively hiding the splicing gaps and making the flatness error of the door surface less than 0.5mm, thus improving the overall aesthetics.

[0033] In this technical solution, the locking component is a stud 6 fixedly connected to the outside of the second door frame 2. At least two studs 6 are provided. A blind hole 5 is provided on the outside of the base plate 4 at the position corresponding to the stud 6. The stud 6 passes through the blind hole 5, and a nut 7 is threaded onto the outside of the stud 6. The locking component adopts a classic mechanical locking structure of "stud 6 + blind hole 5 + nut 7," which features high reliability and convenient maintenance. The stud 6 is made of 304 stainless steel to ensure that the decorative panel 3 does not loosen during long-term use. The blind hole 5 prevents the stud 6 from penetrating the base plate 4, thus avoiding aesthetic issues.

[0034] During installation, the operator simply aligns the blind hole 5 of the base plate 4 with the stud 6, inserts it, and then tightens the nut 7 with a screwdriver to complete the locking process. Disassembly is performed in reverse, without damaging the decorative surface, allowing for quick component replacement. Compared to traditional adhesive fixing, this locking method not only avoids the risk of detachment due to adhesive aging but also supports repeated disassembly and reuse, aligning with green building principles.

[0035] The usage method of this utility model is as follows:

[0036] The first door frame 1 and the second door frame 2 are fixed together, and then the splicing plate 8 is inserted into the first door frame 1 and the second door frame 2. The splicing plate 8 can be slidably inserted through the sliding opening 13.

[0037] After the splicing panel 8 is installed, the remaining second door frame 2 is fixed. Then, the decorative panel 3 is slidably inserted into the outside of the first door frame 1. The first slide bar 10 slides in the first slide groove 9. After the sliding insertion is completed, the second slide bar 12 outside the base plate 4 is inserted into the second slide groove 11, and the stud 6 is aligned with the blind hole 5.

[0038] Then, connect the nut 7 to the stud 6 to fix the base plate 4.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
