Description

Technical Field

[0001] This utility model relates to the field of interior decoration and renovation technology, specifically to an interior finishing strip. Background Technology

[0002] In interior decoration projects, decorative panels (such as wood panels, stone panels, composite panels, etc.) are widely used. To ensure the integrity and aesthetics of the decorative effect, edge trimming strips are needed to treat the edges and joints of the decorative panels. The main function of edge trimming strips is to cover the gaps between decorative panels, protect the edges of the decorative panels from damage, and enhance the overall harmony of the decoration. Currently, most interior panel trim strips on the market are fixed structures, with a fixed distance between the panel and the pressing plate, making them suitable only for decorative panels of specific thicknesses. However, in actual renovations, decorative panel thicknesses vary depending on design requirements and usage scenarios, with different specifications such as 3mm, 5mm, 8mm, and 10mm. This necessitates that construction workers prepare multiple trim strips of different specifications in advance based on the thickness of the decorative panels, increasing procurement costs and inventory management difficulties, and potentially affecting construction progress due to incompatible specifications. Furthermore, during the installation of existing fixed edge trims, if the thickness of the decorative panel does not match the edge trim, problems such as insecure installation and loose joints may occur, leading to loose edge trims and exposed edges of the decorative panel, affecting the decorative effect and service life. Meanwhile, some adjustable edge trims have complex structures, cumbersome adjustment processes, and poor connection stability, making them difficult to meet the needs of actual construction. Therefore, there is an urgent need for an interior finishing strip that can flexibly adjust the distance between the panel and the pressure plate to accommodate decorative panels of different thicknesses, and that is simple in structure, stable in connection, and easy to install. Utility Model Content

[0003] This utility model aims to solve the problems of existing interior finishing strips, such as increased procurement costs, inconvenient construction, and poor installation effect due to the fixed distance between the panel and the pressure plate, which cannot be adapted to decorative panels of different thicknesses. The present invention provides an interior finishing strip with an adjustable distance between the panel and the pressure plate to be suitable for decorative panels of different thicknesses.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an edge trim for interior finishes, comprising: The panel extends in a long strip shape, has an upper surface and a side extending along the length direction, and the side has a downwardly bent arc transition section. The upper connecting part is integrally formed with the panel part, and its cross-section with the panel part is T-shaped. The left and right side walls of the upper connecting part are provided with a grid of teeth, and the teeth are angled upward. The outer edges of the teeth are rounded. The teeth are integrally formed with the upper connecting part. The pressure plate extends in a long strip shape, and the pressure plate has evenly distributed hollow holes; The lower connecting part is integrally formed with the pressure plate part, and its cross-section is L-shaped with that of the pressure plate part. The lower connecting part is provided with a slot that matches the upper connecting part, and the left and right side walls of the slot of the lower connecting part are provided with slots that match the locking teeth. The arc-shaped transition section has a radius of curvature of 3mm-8mm and its surface is polished. The locking teeth are evenly spaced along the length of the left and right side walls of the upper connecting part, with a spacing of 5mm-10mm between adjacent teeth. The hollow holes are circular with a diameter of 2mm-5mm and a center-to-center distance of 6mm-12mm between adjacent holes. The slot depth of the lower connecting part matches the length of the upper connecting part, and the inner wall of the slot is coated with a wear-resistant coating. The upper connecting part, panel part, pressure plate part, and lower connecting part are all made of aluminum alloy and their surfaces are anodized. The number of locking slots corresponds one-to-one with the number of locking teeth, and the inner walls of the locking slots are rounded with a radius of 0.5mm-1.5mm.

[0005] This invention achieves adjustment of the distance between the panel and the pressure plate through the cooperation of the upper and lower connecting parts, thus accommodating decorative panels of different thicknesses. The specific working principle is as follows: The upper connecting part is fixedly connected to the panel part, and the lower connecting part is fixedly connected to the pressure plate part. The upper connecting part can be inserted into the slot of the lower connecting part. The locking teeth arranged in an array on both sides of the upper connecting part are adapted to the locking slots on both sides of the slot of the lower connecting part. Since the teeth are angled upward, when the upper connecting part is inserted into the slot, the teeth will slide in along the inner wall of the locking slot. When the teeth engage with the locking slots at different positions, the insertion depth of the upper connecting part into the slot is different, thereby changing the distance between the panel part and the pressure plate part. For example, when the decorative panel is thinner, it is necessary to reduce the distance between the panel and the pressure plate. The upper connecting part can be further inserted into the slot so that the lower teeth of the upper connecting part engage with the upper slot of the lower connecting part. When the decorative panel is thicker, it is necessary to increase the distance between the panel and the pressure plate. The upper connecting part can be appropriately pulled out of the slot so that the upper teeth of the upper connecting part engage with the lower slot of the lower connecting part. The rounded corners on the outer edge of the locking teeth and the inner wall of the locking slot reduce frictional resistance during the insertion and removal of the upper connector, making the adjustment process smoother and preventing wear caused by sharp edges. The wear-resistant coating on the inner wall of the slot further enhances the wear resistance between the upper and lower connectors, ensuring the service life of the adjustment structure. Furthermore, the perforated holes on the pressure plate allow for securing the trim strip to the base layer using screws or other fasteners, ensuring the trim strip won't shift during use and without affecting the distance adjustment between the panel and the pressure plate. The curved transition section on the side of the panel is polished, which not only enhances the trim strip's aesthetics but also prevents sharp edges from causing scratches. Compared with the prior art, the beneficial effects of this utility model are: This utility model features a spring and a locking screw. Rotating the locking screw pushes the spring, making the spring and clamp highly adjustable. By using different combinations of the teeth of the upper connecting part and the latches of the lower connecting part, the distance between the panel part and the pressure plate part can be flexibly adjusted. It can be adapted to decorative panels of various thicknesses, such as 3mm-20mm, greatly improving the versatility of the trim strip. Stable connection: The tight engagement of the teeth and the jaws, as well as the adaptive design of the upper and lower connecting parts, ensure the stability of the connection between the panel and the pressure plate, and prevent the end strip from loosening during use. Easy to install: The adjustment process is simple and quick, without the need for complicated tools. Construction workers can quickly adjust the distance and install the decorative panel according to its thickness, which improves construction efficiency. Long service life: Made of aluminum alloy and anodized, it has good corrosion resistance and wear resistance. The wear-resistant coating on the inner wall of the slot further extends the service life of the product. High safety: The polished curved transition section and the rounded corner design of each component avoid sharp edges from causing injury to the human body, making it safer to use. Good aesthetics: The overall structural design is simple and elegant, and the surface treatment process gives the trim strip a good appearance, which can match different decoration styles.

[0009] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "Currently, most interior finishing strips on the market have a fixed structure, with a fixed distance between the panel and the pressing plate, which can only accommodate decorative panels of a specific thickness. However, in actual decoration, the thickness of the decorative panels varies depending on design requirements and usage scenarios, such as 3mm, 5mm, 8mm, 10mm, etc. This necessitates that construction workers prepare multiple different specifications of finishing strips in advance according to the thickness of the decorative panels, which not only increases procurement costs and inventory management difficulties but may also affect the construction progress due to incompatible specifications." Furthermore, existing fixed-structure edge trims may experience problems during installation if the thickness of the decorative panel does not match the edge trim, leading to insecure installation and loose joints. This can result in loose edge trims and exposed edges of the decorative panel, affecting the decorative effect and service life. Additionally, some adjustable edge trims have complex structures, cumbersome adjustment processes, and poor connection stability, making them difficult to meet the needs of actual construction. In practical terms, this problem is clearly real and difficult to solve. Therefore, to address this technical issue, an interior finishing edge trim is provided.

[0010] like Figure 1-3 As shown in the figure; This utility model provides a technical solution: an interior finishing strip, comprising a panel part 1, an upper connecting part 2, a pressure plate part 3, and a lower connecting part 4. The panel 1 extends in a long strip with a length of 2000mm. It has an upper surface and a side extending along the length direction. The side has a downward-bending arc transition section with a radius of curvature of 5mm. The surface of the arc transition section is polished to ensure safety and aesthetics. The upper connecting part 2 is integrally formed with the panel part 1, and its cross-section with the panel part 1 forms a T-shape. The length of the upper connecting part 2 is 30mm. The left and right side walls of the upper connecting part 2 are provided with a series of locking teeth 21. The locking teeth 21 are arranged at equal intervals along the length direction on the left and right side walls. The distance between two adjacent locking teeth 21 is 8mm. The teeth of the locking teeth 21 are angled upwards, and the outer edges of the locking teeth 21 are rounded with a radius of 1mm. The locking teeth 21 are integrally formed with the upper connecting part 2. The pressure plate part 3 extends in a long strip shape, with the same length as the panel part 1, which is 2000mm. The pressure plate part 3 is provided with evenly distributed hollow holes 31. The hollow holes 31 are circular with a diameter of 3mm. The center distance between adjacent hollow holes 31 is 10mm, so that the pressure plate part 3 can be fixed by screws or the like. The lower connecting part 4 is integrally formed with the pressure plate part 3, and the cross-section of the lower connecting part 4 and the pressure plate part 3 are L-shaped. The lower connecting part 4 has a slot 41 that matches the upper connecting part 2. The slot 41 has a depth of 30mm, which matches the length of the upper connecting part 2. The inner wall of the slot 41 is coated with a wear-resistant coating to enhance wear resistance. The left and right side walls of the slot 41 of the lower connecting part 4 have slots 42 that match the teeth 21. The number of slots 42 corresponds one-to-one with the number of teeth 21, and the inner wall of the slots 42 is rounded with a radius of 1mm. The upper connecting part 2, the panel part 1, the pressure plate part 3 and the lower connecting part 4 are all made of aluminum alloy and the surface is anodized to improve corrosion resistance and surface hardness. In this embodiment, the distance between the panel part 1 and the pressure plate part 3 is adjusted according to the thickness of the decorative panel during use. When the thickness of the decorative panel is 5mm, the upper connecting part 2 is inserted into the slot 41 of the lower connecting part 4, so that the third tooth 21 from the top on the upper connecting part 2 engages with the third slot 42 from the bottom on the lower connecting part 4. At this time, the distance between the panel part 1 and the pressure plate part 3 is 5mm, which is just right for the decorative panel of this thickness. When the thickness of the decorative panel is 10mm, the upper connecting part 2 is pulled out of the slot 41 appropriately, so that the first tooth 21 from the top on the upper connecting part 2 engages with the first slot 42 from the bottom on the lower connecting part 4. At this time, the distance between the panel part 1 and the pressure plate part 3 is 10mm, which is also suitable for the decorative panel of this thickness. After adjustment, the finishing strip is fixed to the base layer with screws through the hollow holes 31 on the pressure plate part 3, and the panel part 1 covers the edge of the decorative panel to achieve the finishing treatment of the decorative panel.
