[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] This embodiment provides a cabinet door with a large-angle opening and closing function, such as Figures 1 to 3 As shown, it includes: a cabinet door 1, a hinge support rod 2, a top support and a bottom support;

[0039] like Figure 6 and Figure 7 As shown, the cabinet door 1 includes a door panel 101 and a folding edge 102 vertically arranged around the door panel 101. The folding edge 102 is integrally formed with the door panel 101. The top support and the bottom support are located in the cabinet door space formed by the door panel 101 and the folding edge 102, which improves space utilization and makes the overall structure more compact.

[0040] The two hinge support rods 2 are relatively arranged at the top and bottom of the cabinet A, as shown in FIG. Figure 4 and Figure 5 As shown, the hinge support rod 2 includes an integrally formed cabinet body portion 201, an extension portion 202 and a cabinet door portion 203, and the cabinet body portion 201 is fixed to the cabinet body A by bolts;

[0041] The top support and the bottom support are respectively placed on one end of the cabinet door portion 203 of the two hinge support rods 2 away from the extension portion 202, and the two hinge support rods 2 are rotatably connected to the cabinet door 1 through the top support and the bottom support respectively;

[0042] The extension portion 202, the cabinet door portion 203 and the cabinet body A form an escape space. When the cabinet door 1 rotates, the folded edge 102 on the rotating side of the cabinet door 1 can enter the escape space, so that the opening angle of the cabinet door 1 is not less than 90 degrees.

[0043] In this embodiment, if Figure 9 and Figure 10 As shown, the distance between the rotation center line of the cabinet door 1 and the extension 202 (along the length direction of the cabinet door portion 203) is not less than the distance between the rotation center line of the cabinet door 1 and the end of the folding edge 102 on the rotating side of the cabinet door 1 (along the width direction of the folding edge 102), and the distance between the rotation center line of the cabinet door 1 and the cabinet body A (along the length direction of the extension 202) is not less than the distance between the rotation center line of the cabinet door 1 and the end of the folding edge 102 on the rotating side of the cabinet door 1 (along the width direction of the folding edge 102);

[0044] In this embodiment, the cabinet body portion 201 and the extension portion 202 are perpendicular to each other, the extension portion 202 and the cabinet door portion 203 are perpendicular to each other, and the cabinet body portion 201 and the cabinet door portion 203 are parallel to each other. This helps designers to more conveniently confirm the distance between the rotation center line of the cabinet door 1 and the extension portion 202 and the cabinet body A, thereby making the size design of the hinge support rod 2 simpler.

[0045] The cabinet door provided in this embodiment has a large-angle opening and closing function. By providing folding edges 102 around the door panel 101, the cabinet door 1 saves material while maintaining sufficient strength for normal use. The weight reduction makes the cabinet door 1 easier to open and close, and the production cost is lower.

[0046] By forming an escape space between the extension 202 of the hinge support rod 2 and the cabinet door portion 203 and the cabinet body A, when the cabinet door 1 rotates, the folded edge 102 on the rotating side can enter the escape space, so that the rotation angle of the cabinet door 1 is not less than 90 degrees. Specifically, Figure 9 and Figure 10 As shown, by making the distance D2 between the rotation center line of the cabinet door 1 and the cabinet body A not less than the distance D3 between the rotation center line of the cabinet door 1 and the end of the folding edge 102 on the rotating side of the cabinet door 1, the folding edge 102 does not interfere with the cabinet body A when rotating in the avoidance space, ensuring that the cabinet door 1 can be opened and closed smoothly, and by making the distance D1 between the rotation center line of the cabinet door 1 and the extended part 202 not less than the distance D3 between the rotation center line of the cabinet door 1 and the end of the folding edge 102 on the rotating side of the cabinet door 1, the rotation angle of the folding edge 102 is not less than 90 degrees, so that the cabinet door 1 can be opened and closed at a large angle.

[0047] In a specific embodiment, Figure 2 As shown, the top support is a spring latch 3. In this embodiment, the model of the spring latch 3 is CL225-3;

[0048] The hinge support rod 2 further includes a sleeve 204, the axis of which is the rotation centerline of the cabinet door 1. The sleeve 204 is welded to the end of the cabinet door portion 203 away from the extension portion 202. The hinge 302 of the spring latch 3 is fixed to the cabinet door 1 by bolts, and the latch 301 of the spring latch 3 is inserted into the sleeve 204 from bottom to top.

[0049] When the cabinet door 1 needs to be installed, the latch 301 is pulled downward, and the spring 303 of the spring latch 3 is compressed. After releasing the hand, the spring 303 releases the elastic force, and the latch 301 is inserted into the sleeve 204 from bottom to top. When the cabinet door 1 needs to be disassembled, the latch 301 is pulled downward, and the spring 303 of the spring latch 3 is compressed, and the latch 301 is pulled out of the sleeve 204. The disassembly and assembly process of the cabinet door 1 is simple and labor-saving.

[0050] In a specific embodiment, Figure 3 As shown, the bottom support is a pin 4;

[0051] like Figure 8As shown, a connecting plate 104 is vertically fixed on the folding edge 102 on the rotating side of the cabinet door 1, and a mounting plate 103 is vertically fixed on the connecting plate 104. The mounting plate 103 is provided with a pin hole, and the bottom end of the pin 4 is inserted into the sleeve 204, and is loosely matched with the sleeve 204. The top end of the pin 4 is inserted into the pin hole, and a limiting protrusion 401 is provided in the middle of the pin 4. The two ends of the limiting protrusion 401 respectively abut the top end of the sleeve 204 and the bottom end of the mounting plate 103. The pin 4 is pressed on the sleeve 204 by the cabinet door 1. When the cabinet door 1 needs to be disassembled, the pin 301 is pulled out from the sleeve 204, and the cabinet door 1 can be lifted to remove the pin 4.

[0052] In a specific embodiment, Figure 7 As shown, it also includes a pad 5, which is welded and fixed on the door panel 101. The hinge 302 is detachably connected to the pad 5 by bolts. The pad 5 provides an installation base for the hinge 302 to reduce the thickness requirement for the cabinet door 1, thereby reducing the weight of the cabinet door 1.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
