Technical Field
[0001] This utility model relates to the technical field of wooden door decorative strips, specifically to a wooden door decorative strip. Background Technology
[0002] Door trim strips are components used to enhance the aesthetics of wooden doors. They not only cover the gaps between the door and the frame but also add a unique style through different materials, colors, and shapes, matching various interior design styles. Currently available trim strips are mostly nailed or adhesive. Nail-mounted trim strips are fixed to the door edge or frame with nails, offering a relatively simple decorative effect. However, they require skilled installers, as misaligned or excessively deep nails can damage the trim strip or the door surface, and exposed nails detract from the overall appearance. Adhesive trim strips are glued to the door edge or frame with adhesive or other bonding agents. Once glued, they are difficult to reposition, and the adhesive is prone to aging, leading to strip detachment. Most importantly, the adhesive may contain excessive formaldehyde, affecting the health of residents.
[0003] In addition to the problems mentioned above, both nail-mounted and adhesive decorative strips are disposable products. Once installed, they are difficult to remove and can easily damage the wooden door and the decorative strip itself. It is also difficult to modify the wooden door or replace the decorative strip later. Therefore, this utility model proposes a wooden door decorative strip that is easy to install and remove.

[0028] Example
[0029] like Figure 1-5 As shown, a wooden door decorative strip includes a door panel 1, and a first decorative strip 2 and two second decorative strips 3 disposed on the door panel 1. The two second decorative strips 3 are disposed at both ends of the first decorative strip 2. Both the first decorative strip 2 and the second decorative strip 3 include a decorative surface and an installation surface. A snap-fit device is provided on the installation surface of the first decorative strip 2. The snap-fit device includes two sets of snap-fit pieces arranged symmetrically and several springs 22. The springs 22 are disposed between the two sets of snap-fit pieces. A blocking block 31 is provided on the installation surface of the second decorative strip 3. A first slot 11 and two second slots 12 are opened on the door panel 1. The two second slots 12 are disposed at both ends of the first slot 11. The first slot 11 is a T-shaped slot. The snap-fit pieces match the first slot 11.
[0030] It is worth noting that the first decorative strip 2 cooperates with the first slot 11 through a snap-fit device. Two sets of symmetrically arranged snap-fit pieces are snapped at the corner of the T-shaped slot to fix the first decorative strip 2 to the door panel 1, ensuring that the first decorative strip 2 does not fall off the door panel 1. The spring 22 can open the two sets of snap-fit pieces to prevent the snap-fit pieces from aging and falling off or becoming unstable after long-term use. However, the snap-fit pieces can slide in the first slot 11 of the T-shape. Through the cooperation of the blocking block 31 with the second slot 12, the second decorative strip 3 is fixed to the door panel 1, and the two second decorative strips 3 are fixed at both ends of the first decorative strip 2. At this time, the blocking block 31 is located at both ends of the first slot 11, which can restrict the relative movement of the snap-fit pieces and the first slot 11, ensuring the stable installation of the first decorative piece.
[0031] Furthermore, when installing the first decorative strip 2 and the second decorative strip 3, firstly, directly align the snap-fit device with the first snap-fit groove 11 and apply force. The two sets of symmetrically arranged snap-fit pieces will converge inward and slide into the first snap-fit groove 11. After they are fully slid in, the two sets of snap-fit pieces will return to their original positions and, under the action of the spring 22, will expand to both ends to engage with the bend of the T-shaped structure of the first snap-fit groove 11. After the first decorative strip 2 is installed, the plug 31 will be placed into the second snap-fit groove 12, and the second decorative strip 3 will be installed.
[0032] When it is necessary to remove the first decorative strip 2 and the second decorative strip 3, first remove the blocking block 31 from the second slot 12. At this time, the snap-fit part can slide in the first slot 11, and the second slot 12 provides sliding allowance for the snap-fit part. Simply slide the snap-fit part into the second slot 12 from either end of the first slot 11, and then pull it out directly. This facilitates the replacement of aging and damaged first decorative strip 2 and second decorative strip 3, and can adapt to different styles of decoration. Only the decorative strips need to be replaced to achieve the renovation of the door panel 1, reducing the cost. Moreover, when changing the color of the door panel 1 or applying protective film and color-changing film, the first decorative strip 2 and second decorative strip 3 can be removed first, and the door panel 1 can be operated on separately. Finally, the first decorative strip 2 and second decorative strip 3 can be installed, which is beneficial to the overall aesthetics.
[0033] In some feasible embodiments, the first decorative strip 2 and the second decorative strip 3 are elastic structures, which facilitates the installation and removal of the first decorative strip 2 and the second decorative strip 3. In particular, when the first decorative strip 2 is pulled out from the first slot 11, the first decorative strip 2 will undergo slight deformation, which facilitates the smooth operation of pulling it out.
[0034] Furthermore, when the first slot 11 and the second slot 12 are arc-shaped, the first decorative strip 2 and the second decorative strip 3 can also be adapted for installation due to the elastic force of the elastic structure.
[0035] In some feasible embodiments, the snap-fit component includes a plurality of snap-fit plates 21, which are arranged sequentially from left to right on the decorative surface of the first decorative strip 2. A gap is provided between adjacent snap-fit plates 21. Each snap-fit plate 21 includes a vertical section and an inclined section. The inclined section is located at the end of the vertical section away from the first decorative strip 2, and on opposite sides of the snap-fit plates 21 of the two sets of snap-fit components. The end of the inclined section closest to the first decorative strip 2 is away from the vertical section of the snap-fit plate 21. After the inclined section of the snap-fit plate 21 is fully inserted into the first slot 11, the inclined section unfolds and hooks onto the bend of the T-shaped structure of the first slot 11, fixing the first decorative strip 2 to the door panel 1.
[0036] Several locking plates 21 are provided so that, in order to accommodate the first decorative strip 2 which has a certain elasticity, when the first decorative strip 2 bends, the several locking plates can bend along with it without restricting the bending of the first decorative strip 2.
[0037] In some feasible embodiments, the card plate 21 is an elastic structure, which makes it easy for the card plate 21 to undergo elastic deformation and be inserted into the first card slot 11, and then return to its original shape, so that the card plate 21 and the first card slot 11 are firmly engaged.
[0038] In some feasible embodiments, the length of the blocking block 31 is greater than the length of the second slot 12, so that the blocking block 31 and the second slot 12 form an interference fit, and the blocking block 31 is not easy to fall out of the second slot 12.
[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art. The various embodiments of this disclosure have been described in detail above. To avoid obscuring the concept of this disclosure, some details known in the art have not been described.
