[0022] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0023] This application discloses a double-folding door cabinet, including a cabinet body 1 with an opening and cabinet doors installed on the cabinet body 1 for opening and closing. The opening is located at each end, thus two cabinet doors are also symmetrically arranged.
[0024] The cabinet door comprises a first door body 2 and a second door body 3. The height of the first door body 2 is three times the height of the second door body 3. The upper end of the first door body 2 is hinged to the cabinet body 1, and the lower end of the first door body 2 is hinged to the upper end of the second door body 3. A gas spring 4 is installed between the first door body 2 and the cabinet body 1, with one end of the gas spring 4 hinged to the first door body 2 and the other end hinged to the cabinet handle. The cabinet body 1 protrudes outward to form a rainproof frame 5. When the cabinet door is closed, the inner side of the cabinet door abuts against the end wall of the cabinet body 1, and the outer side of the cabinet door is flush with the outer wall of the rainproof frame 5. A first sealing structure is formed between the upper end of the cabinet body 1 and the first door body 2, a second sealing structure is formed between the first door body 2 and the second door body 3, and a third sealing structure is formed between the lower end of the second door body 3 and the lower end of the cabinet body 1. The triple sealing structure ensures the airtightness of the cabinet door. Generally, two door locks 6 are installed on the second door body 3. The door locks 6 can be any lock, as long as they can lock. For example, the structure of CN207960222U, CN203729715U, and CN213391623U can be referenced.
[0025] The upper end of the first door 2 forms a first connecting edge 7, and the upper end of the cabinet 1 forms a horizontal second connecting edge 8. The first connecting edge 7 and the second connecting edge 8 are hinged together by a first hinge 9. In this embodiment, the first hinge is a hinge, and the two sides of the hinge are fixed to the first connecting edge 7 and the second connecting edge 8 by screws.

The first guide edge 10 is integrally formed with the first connecting edge 7, and the guide groove 11 is integrally formed with the cabinet body 1. The end of the first guide edge 10 extends above the guide groove 11. The guide groove 11 includes a first guide portion 12, a second guide portion 13, and a third guide portion 14. The first guide portion 12 is integrally formed with the second connecting edge 8 and is vertically arranged. The second guide portion 13 is integrally formed with the first guide portion 12 and is horizontally arranged. The third guide portion 14 is integrally formed with the second guide portion 13 and is vertically arranged. The first guide edge 10 is located directly above the second guide portion 13.
[0027] The second sealing structure includes a first bend 15, a second bend 16, a third bend 17, a fourth bend 18, and a fifth bend 19. The first bend 15 is integrally formed with and perpendicular to the lower end of the first door body 2; the second bend 16 is integrally formed with and perpendicular to the first bend 15; the third bend 17 is integrally formed with and perpendicular to the second bend 16; the fourth bend 18 is integrally formed with and perpendicular to the upper end of the second door body 3; and the fifth bend 19 is integrally formed with and perpendicular to the fourth bend 18. The second bend 16 and the fifth bend 19 are hinged together by a second hinge (not shown in the figure). In this embodiment, the second hinge is a hinge, and the two sides of the hinge are fixed to the second bend 16 and the fifth bend 19 by screws.
[0028] The third sealing structure includes a first folded edge 21, a second folded edge 22, a third folded edge 23, and a fourth folded edge 24. The first folded edge 21 is integrally formed with and perpendicular to the lower end of the second door 3; the second folded edge 22 is integrally formed with and perpendicular to the first folded edge 21; the third folded edge 23 is integrally formed with the cabinet 1 and bends horizontally inward; the fourth folded edge 24 is integrally formed with and vertically positioned relative to the third folded edge 23; the first folded edge 21 is located above and spaced apart from the third folded edge 23; and the second folded edge 22 abuts against the fourth folded edge 24. The third sealing structure also includes a fifth folded edge 25 and a sixth folded edge 26. The fifth folded edge 25 is integrally formed with and horizontally positioned relative to the fourth folded edge 24; and the sixth folded edge 26 is integrally formed with and vertically positioned relative to the fifth folded edge 25. When the second door 3 is closed, the sixth folded edge 26 is spaced apart from the second door 3.
[0029] To increase the strength of the cabinet door, a reinforcing frame 20 can be fixed inside the cabinet door. The reinforcing frame includes two parallel vertical rods 27, which are welded to the first door body 2. The two ends of the horizontal rod 28 are fixed to the two vertical rods 27 respectively.
