[0016] In order to better understand the purpose, structure and function of this utility model, Figures 1 to 4 , a curved door of the utility model is further described in detail.

[0017] like Figures 1 to 4 As shown, an embodiment of the present invention provides a curved door. The device includes an inner door mounting platform 100 and a sliding hinge assembly 200. The inner door mounting platform 100 is fixedly connected to the curved door. In some embodiments, the inner door mounting platform 100 and the curved door can be an integrated design. The inner door mounting platform 100 also includes a planar hinge mounting surface 110 for connection to the sliding hinge assembly 200.

[0018] In the present invention, the sliding hinge assembly 200 includes a hinge fixing portion 210 and a hinge sliding portion 220, wherein the hinge sliding portion 220 further includes a hinge sliding rod 221, a hinge sliding assembly 222 and a sliding groove base 223, wherein the hinge sliding assembly 222 is a hollow structure and is slidingly connected to the hinge sliding rod 221 in the middle. Not only that, the hinge sliding assembly 222 is also fixedly connected to the sliding groove base 223, and the sliding groove base 223 is detachably connected to the cabinet side wall 300. When in use, the sliding groove base 223 is installed on the cabinet side wall 300. In order to replace the sliding hinge assembly 200, the sliding groove base 223 is installed on the cabinet side wall 300 in a detachable manner. For example, the sliding groove base 223 can be installed on the cabinet side wall 300 with screws. The hinge fixing portion 210 includes a hinge fixing base 211 and a hinge telescopic pull rod 212. For ease of disassembly, the hinge fixing base 211 is mounted to the hinge mounting surface 110 via screws, allowing the hinge fixing base 211 to be detachably connected to the hinge mounting surface 110. The hinge fixing base 211 is rotatably connected to the hinge telescopic pull rod 212, which in turn is rotatably connected to the hinge sliding rod 221. When the curved door is opened or closed, rotation occurs between the hinge fixing base 211 and the hinge telescopic pull rod 212, and between the hinge telescopic pull rod 212 and the hinge sliding rod 221. The angle α between the hinge fixing base 211 and the sliding groove base 223 in a direction perpendicular to the hinge mounting surface 110 and the cabinet side wall 300 is 90° to 180°. That is, when the curved door is in a closed state, the hinge mounting surface 110 is perpendicular to the cabinet side wall 300; when the curved door is in a fully open state, the hinge mounting surface 110 and the cabinet side wall 300 are on the same plane; when the curved door is neither closed nor fully opened, the angle between the hinge mounting surface 110 and the cabinet side wall 300 is between 90° and 180°; the inner side mounting platform 100 of the door and the cabinet side wall 300 are rotatably connected.

[0019] There are four sides on the curved door, namely the first side 400, the second side 500, the third side 600 and the fourth side 700, among which the fourth side 700 is the side farthest from the sliding hinge assembly 200, and the first side 400 and the second side 500 are perpendicular to the fourth side 700, and the third side 600 and the fourth side 700 are parallel.

[0020] In the present invention, the door inner side mounting platform 100 extends from the first side 400 to the second side 500, and in the vertical direction, the door inner side mounting platform 100 runs through the entire curved door; in the horizontal direction, the door inner side mounting platform 100 extends from the third side 600 to the fourth side 700. Assuming that the extension distance is a centimeter, that is, the width of the hinge mounting surface 110 is a centimeter, and it can be known that the length of the hinge fixing base 211 is b centimeters, then a≥b. This design can ensure that the sliding hinge assembly 200 can be stably installed on the hinge mounting surface 110, and the installation of the sliding hinge assembly 200 will not be unstable because the hinge length is larger than the hinge mounting surface 110.

[0021] During use, the hinge's sliding groove base 223 is first screwed to the cabinet side wall 300, and then the hinge fixing base 211 is screwed to the hinge mounting surface 110. Since the hinge mounting surface 110 is a flat surface, the curved surface of the curved door will not affect the installation of the sliding hinge assembly 200. When the curved door is pulled, the angle between the hinge mounting surface 110 and the cabinet side wall 300 gradually increases, but does not exceed 180 degrees. During this process, the hinge fixing base 211 and the hinge telescopic pull rod 212 rotate, and the hinge telescopic pull rod 212 rotates with the hinge sliding rod 221, pulling the hinge sliding rod 221 out of the hinge sliding assembly 222. When the angle between the hinge mounting surface 110 and the cabinet side wall 300 reaches 180 degrees, the curved door reaches its maximum opening angle, at which point the hinge sliding rod 221 is still partially in the hinge sliding assembly 222. When the curved door is pushed to close, the angle between the hinge mounting surface 110 and the cabinet side wall 300 gradually decreases, reaching a minimum of no less than 90°. During the closing process, the hinge fixing base 211 and the hinge telescopic pull rod 212 rotate, which in turn rotates with the hinge sliding rod 221, pushing the portion of the hinge sliding rod 221 outside the hinge sliding assembly 222 back into the hinge sliding assembly 222. When the angle between the hinge mounting surface 110 and the cabinet side wall 300 decreases to 90°, the curved door is closed.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
