[0019] The following is combined with Figure 1-4 The present invention is further described in detail with reference to the following specific embodiments, but they are not intended to limit the present invention:

[0020] Example 1

[0021] like Figure 1-Figure 4 As shown, a door structure for a kitchen includes a door frame 1 and a door panel 2 rotatably arranged in the door frame 1, and also includes a small door 3 and a telescopic locking assembly 4. The inner surface of the small door 3 is provided with a first handle 5, and a mounting groove 21 is opened on the door panel 2. The lower end of the small door 3 is rotatably arranged at the bottom of the mounting groove 21, one end of the telescopic locking assembly 4 is rotatably arranged on the inner surface of the door panel 2, and the other end of the telescopic locking assembly 4 is rotatably arranged on the inner surface of the small door 3, and the telescopic locking assembly 4 extends outward or contracts inward to form an extended state and a contracted state; an open state and a closed state are formed between the door panel 2, the small door 3, and the telescopic locking assembly 4. In the open state, the small door 3 is rotated outward to be placed horizontally, and the telescopic locking assembly 4 extends outward with the small door 3 and maintains in the extended state. In the closed state, the small door 3 is rotated inward to be vertically arranged and inserted into the mounting groove 21, and the telescopic locking assembly 4 contracts inward with the small door 3 and maintains in the contracted state. The telescopic locking assembly 4 is vertically arranged.

[0022] Preferably, the telescopic locking assembly 4 includes an inner rod 41, an outer rod 42 and a button 43. The lower end of the outer rod 42 is rotatably set on the inner surface of the small door 3, and the upper end of the outer rod 42 is slidably sleeved on the outside of the inner rod 41. The upper end of the inner rod 41 passes through the outer rod 42 and is rotatably set on the inner surface of the door panel 2; a locking hole 411 is opened on the inner rod 41, and a first locking plate 412 is set on the outer side wall of the inner rod 41. There is a second locking plate 421, one end of the button 43 passes through the outer rod 42 and is interference fit with the outer rod 42. In the closed state, the outer rod 42 slides toward the upper end of the inner rod 41, and the end of the button 43 is inserted into the locking hole 411. In the open state, the button 43 withdraws from the locking hole 411, and the outer rod 42 slides toward the upper end away from the inner rod 41 to the first locking plate 412 and abuts against the second locking plate 421.

[0023] Preferably, the small door 3 includes a main board 31 and a pull-out plate 32. The pull-out plate 32 is slidably arranged in the main board 31. An expanded state and a stored state are formed between the main board 31 and the pull-out plate 32. In the expanded state, the pull-out plate 32 slides into place in a direction away from the main board 31. The pull-out plate 32 and the main board 31 are horizontally arranged. In the stored state, the pull-out plate 32 retreats into the main board 31. The first handle 5 is arranged on the inner surface of the main board 31.

[0024] Preferably, a guide bar 6 is provided at the side end of the pull-out plate 32, and an outer limit block 61 and an inner limit block 62 are respectively provided at the front and rear ends of the guide bar 6, and a clearance area 7 is formed between the outer limit block 61, the inner limit block 62 and the guide bar 6; a slide rail 8 is provided in the main board 31, and a positioning plate 81 is provided in the slide rail 8, the guide bar 6 is inserted into the slide rail 8 and slides along the slide rail 8, and the positioning plate 81 is inserted into the clearance area 7; in the expanded state, the inner limit block 62 is abutted against the rear end of the positioning plate 81, and in the retracted state, the outer limit block 61 is abutted against the front end of the positioning plate 81.

[0025] Preferably, a second handle 321 is provided at the front end of the pull-out plate 32 .

[0026] Specifically, in the embodiment of the present application, there are two telescopic locking assemblies 4, which are distributed on both sides of the main board 31. The lower end of the main board 31 is rotatably connected to the bottom of the mounting groove 21 via a hinge, and the small door 3 rotates vertically around the bottom of the mounting groove 21.

[0027] More specifically, when the small door 3 needs to be opened, the button 43 is first pulled outward until the end of the button 43 exits the locking hole 411. The small door 3 is then pushed outward. At this time, the lower end of the outer rod 42 rotates outward along with the small door 3 around the upper end of the inner rod 41, and the outer rod 42 moves and extends away from the upper end of the inner rod 41. When the small door 3 is placed horizontally, the first locking plate 412 and the second locking plate 421 abut against each other, and the small door 3 is now in the open state. The second handle 321 is used to pull the pull-out plate 32 outward until the inner limit block 62 abuts against the positioning plate 81. At this point, the small door 3 is maintained in the extended state, and the user can place dishes or plates through the small door 3.

[0028] When the small door 3 is to be stored on the door panel 2 after use, the second handle 321 is used to push the pull-out plate 32 inwardly into the main plate 31. The small door 3 can then be rotated inwardly from the outside. At this time, the lower end of the outer rod 42 rotates inwardly around the upper end of the inner rod 41, and the outer rod 42 moves toward the upper end of the inner rod 41. When the small door 3 is placed vertically, the locking hole 411 and the button 43 are aligned. The button 43 is pressed inward until the end of the button 43 is inserted into the locking hole 411, thereby maintaining the small door 3 in the closed state.

[0029] The small door 3 can be maintained in an open or closed state through the telescopic locking assembly 4. On the one hand, dishes or plates can be placed directly on the small door 3 for users to take without opening the door panel 2, thereby reducing the spread of oil smoke from the kitchen to the outside. On the other hand, the main board 31 and the pull-out plate 32 increase the area of ​​the small door 3 for placing dishes and plates, making it convenient to use.

[0030] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made within the scope of the patent application for the present invention should fall within the scope of the present invention.
