Description

Technical Field

[0001] This utility model mainly relates to the field of acrylic sheet processing technology, specifically an acrylic cabinet door. Background Technology

[0002] Acrylic cabinet doors are cabinet doors made primarily of acrylic (polymethyl methacrylate). They feature high transparency, good corrosion resistance, and ease of processing. They provide protection for the cabinet while also offering a certain degree of decoration, allowing for a clear view of the equipment inside. They are widely used in various scenarios requiring cabinets.

[0003] The edges of existing acrylic cabinet door panels lack additional protection. During handling, installation, or use, the edges are easily damaged by collisions, such as cracks or missing corners, affecting aesthetics and functionality. Moreover, the edges are easily scratched when in contact with other objects. Once the edges are damaged, it is usually difficult to repair the edge alone, and the entire panel often needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the edges of existing acrylic cabinet door panels lack additional protection and are prone to damage, and to propose an acrylic cabinet door.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An acrylic cabinet door includes a door panel body. U-shaped slots are provided on all four sides of the door panel body. Two first U-shaped protective rods and two second U-shaped protective rods are symmetrically arranged and slidably engaged in the four U-shaped slots. Two elongated slots are provided on the inner walls of both ends of the two first U-shaped protective rods. Two elongated blocks are fixedly connected to both ends of the two second U-shaped protective rods. The elongated blocks on the two second U-shaped protective rods are slidably engaged in the elongated slots in the two first U-shaped protective rods.

[0007] As a further description of the above technical solution, two receiving grooves are respectively opened at the middle of both ends of the door panel body. Limiting blocks are slidably installed in both receiving grooves. One end of each limiting block passes through the outer surface of one side of the two first U-shaped protective rods and is slidably connected to the two first U-shaped protective rods respectively. Two springs are fixedly installed between the two limiting blocks and the inner walls of the two receiving grooves respectively.

[0008] As a further description of the above technical solution, both ends of the second U-shaped protective rod are fixedly connected to cover plates, and the two cover plates are slidably engaged with the same end of the two first U-shaped protective rods respectively. An installation groove is provided on the side of the second U-shaped protective rod away from the door panel body.

[0009] As a further description of the above technical solution, the door panel body is provided with several heat dissipation holes.

[0010] As a further description of the above technical solution, the door panel body has an installation hole on one side near several heat dissipation holes, and the door panel body has two grooves at both ends of the installation hole, and an elongated plate is slidably installed in each of the two grooves.

[0011] As a further description of the above technical solution, two elongated holes are respectively opened at both ends of the first U-shaped protective rod away from the limiting block. A protective plate is slidably installed in each of the two elongated holes. Limiting rods are fixedly connected to both sides of the two protective plates. Limiting grooves are opened on both sides of the inner wall of the two elongated holes. The limiting rods at both ends of the two protective plates are slidably installed in the limiting grooves on the inner wall of the two elongated holes.

[0012] As a further description of the above technical solution, the door panel body includes, from the inner layer to the outer layer, a heat-resistant board, a hardened board, and a wear-resistant coating. The hardened board is tightly attached to the outer surface of the heat-resistant board, and the wear-resistant coating covers the outer surface of the hardened board.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, by setting a first U-shaped protective rod and a second U-shaped protective rod on the four sides of the door panel body, comprehensive protection can be provided for the four sides of the door panel body, effectively preventing damage such as collisions and scratches to the edges of the door panel during handling and use. The first U-shaped protective rod and the second U-shaped protective rod are connected to each other through the cooperation of elongated blocks and elongated slots to form a stable protective structure. This connection method can provide support and constraint in multiple directions, enhance the connection strength between the protective rod and the door panel body, and make the protective rod less likely to fall off or deform when subjected to external forces, thereby better playing its protective role and ensuring the safety and reliability of the cabinet door during use. Moreover, when the protective rod is damaged due to accident or wear due to long-term use, because it adopts a sliding snap connection method, the damaged protective rod can be replaced individually simply by sliding it out of the U-shaped slot, without disassembling the entire cabinet door or performing large-scale repair operations on the door panel, reducing maintenance costs and difficulty.

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0024] Please refer to the appendix carefully. Figures 1-6 As shown, this utility model provides a technical solution: an acrylic cabinet door, including a door panel body 10, with U-shaped slots 104 on all four sides of the door panel body 10. The four U-shaped slots 104 are respectively slidably engaged with two first U-shaped protective rods 20 and two second U-shaped protective rods 21 arranged symmetrically. The inner walls of both ends of the two first U-shaped protective rods 20 are provided with two elongated slots 202. The two ends of the two second U-shaped protective rods 21 are fixedly connected with two elongated blocks 212. The elongated blocks 212 on the two second U-shaped protective rods 21 are respectively slidably engaged in the elongated slots 202 in the two first U-shaped protective rods 20.

[0025] Specifically, by providing two first U-shaped protective bars 20 and two second U-shaped protective bars 21 on the four sides of the door panel body 10, effective protection is provided for the four sides of the door panel body 10, preventing damage such as collisions and scratches to the edges of the door panel during handling and use. The two first U-shaped protective bars 20 and the two second U-shaped protective bars 21 are connected to each other by the sliding engagement of the elongated locking block 212 and the elongated locking groove 202, forming an interconnected protective frame. This connection method provides additional structural support for the entire cabinet door, improves the overall structural stability of the cabinet door, and enables the cabinet door to better resist deformation when subjected to external forces. Furthermore, through the sliding engagement of the elongated locking block 212 and the elongated locking groove 202, when the two first U-shaped protective bars 20 and the two second U-shaped protective bars need maintenance or replacement due to long-term use or accidental damage, they can be easily slid out of the U-shaped locking groove 104 and the elongated locking groove 202 for individual repair or replacement.

[0026] In one embodiment of this utility model, such as Figure 3 As shown, two receiving grooves 108 are respectively opened at the middle of both ends of the door panel body 10. Limiting blocks 12 are slidably installed in both receiving grooves 108. One end of the two limiting blocks 12 passes through the outer surface of one side of the two first U-shaped protective rods 20 and is slidably connected to the two first U-shaped protective rods 20 respectively. Two springs 13 are fixedly installed between the two limiting blocks 12 and the inner walls of the two receiving grooves 108 respectively. By pressing the limiting blocks 12 to compress the springs 13, the limiting blocks 12 are disengaged from the first U-shaped protective rods 20, further releasing the locking of the first U-shaped protective rods 20, making it easy to remove the first U-shaped protective rods 20 from the door panel body 10. Conversely, the limiting blocks 12 can ensure that the first U-shaped protective rods 20 can move within a certain range, preventing them from being displaced by accidental external forces, thereby ensuring the positional accuracy of the first U-shaped protective rods 20 relative to the door panel body 10 and avoiding misalignment or deviation from the predetermined position of the first U-shaped protective rods 20 during use.

[0027] In one embodiment of this utility model, such as Figure 5 As shown, both ends of the second U-shaped protective rod 21 are fixedly connected to cover plates 213. The two cover plates 213 are slidably engaged with the same end of the two first U-shaped protective rods 20. The second U-shaped protective rod 21 has an installation groove 211 on the side away from the door panel body 10. The cover plates 213 can cover both ends of the first U-shaped protective rod 20 to prevent external dust from entering the first U-shaped protective rod 20 and contaminating the corners of the door panel body 10. The main function of the installation groove 211 is to install pulleys so that the acrylic cabinet door can be used as a sliding door.

[0028] In one embodiment of this utility model, such as Figure 1 and Figure 2As shown, the door panel body 10 has several heat dissipation holes 105 to facilitate heat dissipation inside the cabinet.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the door panel body 10 has a mounting hole 107 on one side near several heat dissipation holes 105. The door panel body 10 has two grooves 106 at both ends of the mounting hole 107. An elongated plate 11 is slidably installed in each of the two grooves 106. When the cabinet door is used as a flip door, the mounting hole 107 is provided for installing a lock. When the cabinet door is used as a sliding door, the elongated plate 11 is used to block the mounting hole 107, while the groove 106 is used to push the cabinet door to move.

[0030] In one embodiment of this utility model, such as Figure 2 and Figure 6 As shown, one of the first U-shaped protective rods 20 has two elongated holes 201 at each end on the side away from the limiting block 12. Protective plates 22 are slidably installed in both elongated holes 201. Limiting rods 221 are fixedly connected to both sides of the two protective plates 22. Limiting grooves 203 are opened on both sides of the inner wall of the two elongated holes 201. The limiting rods 221 at both ends of the two protective plates 22 are slidably installed in the limiting grooves 203 on the inner wall of the two elongated holes 201. When the cabinet door is used as a flip door, by pulling the protective plate 22, the limiting rods 221 slide away from the surface of the first U-shaped protective rod 20 in the limiting grooves 203, which facilitates the direct installation of hinges on the acrylic plate.

[0031] In one embodiment of this utility model, such as Figure 4 As shown, the door panel body 10 includes a heat-resistant sheet 101, a hardened sheet 102 and a wear-resistant coating 103 from the inner layer to the outer layer. The hardened sheet 102 is tightly attached to the outer surface of the heat-resistant sheet 101, and the wear-resistant coating 103 covers the outer surface of the hardened sheet 102.

[0032] Specifically, heat-resistant sheet 101 is an acrylic sheet containing heat-resistant additives. During the acrylic raw material production process, 3%-5% of organosilicon heat-resistant additives are added. These additives have good compatibility with acrylic molecules and can be evenly dispersed inside the sheet. When the panel is in a high-temperature environment, the organosilicon heat-resistant additives increase the intermolecular forces of acrylic molecules, enhance thermal stability, and effectively improve the high-temperature resistance of the acrylic cabinet door panel. Hardened sheet 102 is an acrylic sheet that has undergone chemical hardening treatment. This treatment is achieved by immersing the acrylic sheet in a solution containing a specific metal salt (such as potassium nitrate solution). In a liquid, an ion exchange reaction is carried out at 400-450℃. The reaction causes potassium ions in the solution to exchange with sodium ions on the acrylic surface, forming a hard potassium-rich layer. This potassium-rich layer significantly improves the hardness of the acrylic surface and enhances the wear resistance of the entire panel. The wear-resistant coating 103 is based on polyurethane and contains nano-sized silica particles. The flexibility and adhesion of polyurethane allow the coating to adhere firmly to the underlying material and has a certain degree of elastic deformation when scratched to protect the internal structure. The nano-silica particles resist friction with their high hardness, preventing the panel from being scratched.

[0033] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
