Description

Technical Field

[0001] The utility model relates to the technical field of disinfection cabinets, in particular to a hinge structure of an embedded disinfection cabinet and the disinfection cabinet. Background Art

[0002] In the disinfection cabinets currently on the market, the door body is hinged to the cabinet body of the disinfection cabinet through a hinge, so as to realize the rotation opening and closing of the door body. The existing hinge guides the door body's opening and closing track to occupy a large space, which will lead to a low space utilization rate of the disinfection cabinet. In order to avoid friction between the door body and the cabinets next to it when opening and closing, it is necessary to appropriately increase the gap between the disinfection cabinet and the cabinet, which directly affects the user's experience and aesthetics. Chinese patent documents CN209713747U, CN210622555U, and CN210439850U respectively disclose traditional hinge structures. This type of hinge structure is a single-axis structure, so the opening and closing action amplitude of the door body is large, and more space needs to be reserved, so the space utilization rate is low. Therefore, it is necessary to make further improvements to the existing disinfection cabinets. Utility Model Content

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] See also Figure 1-Figure 20 The hinge structure of the embedded disinfection cabinet involved in this embodiment can increase the use space of the disinfection cabinet. The hinge structure includes a hinge assembly 2 installed on a cabinet body 1. A door body assembly 3 is provided on the front side of the cabinet body 1 for rotating opening and closing. A first hinge shaft 4 and a second hinge shaft 5 are provided on the hinge assembly 2. A first track groove 6 and a second track groove 7 are provided on the door body assembly 3. When the door body assembly 3 is opened or closed, the first hinge shaft 4 slides on the first track groove 6, and the second hinge shaft 5 slides and rotates on the second track groove 7 (according to actual conditions, the second hinge shaft 5 can slide or rotate on the second track groove 7). In this hinge structure, when the door body assembly 3 is fully opened from the second active position B, the first hinge shaft 4 slides on the first track groove 6, the second hinge shaft 5 rotates on the second track groove 7, and the door body assembly 3 rotates around the second hinge shaft 5 to open. In addition, the first track groove 6 limits the first hinge shaft 4, and the space required for the door body assembly 3 to open and close is reduced, thereby increasing the usable space of the disinfection cabinet; when the disinfection cabinet and the cabinet are arranged side by side, the door body assembly that uses this hinge structure to realize the opening and closing action can reduce the gap between the disinfection cabinet and the cabinet without friction with the cabinet, thereby increasing the usable space of the disinfection cabinet, ensuring the smoothness of opening and closing the door, and increasing the aesthetics of the product.

[0029] See also Figure 2 , the second track groove 7 includes a first sliding area 8, a first turning area 9 and a second sliding area 10, the first sliding area 8 is connected to the second sliding area 10 through the first turning area 9, and the first sliding area 8 and the second sliding area 10 form a certain angle with each other, that is, the directions of the first sliding area 8 and the second sliding area 10 are different; when the door body assembly 3 is in the closed position and the first active position A ( Figure 3 and Fig.10 The second hinge shaft 5 slides along the first sliding area 8 when the door assembly 3 moves between the first active position A and the second active position B ( Figure 5 and Figure 8The second hinge shaft 5 slides from the first turning area 9 into the second sliding area 10 when the door assembly 3 moves between the second active position B and the open position; the second hinge shaft 5 rotates relative to the end of the second sliding area 10; the first turning area 9 is arc-shaped. With the cooperation of the second track groove 7 and the second hinge shaft 5, the position of the second hinge shaft 5 relative to the door assembly 3 changes, reducing the space occupied by the door assembly 3.

[0030] See also Figure 2 The first track groove 6 includes a third sliding area 13, a second turning area 11 and a fourth sliding area 14 which are connected to each other; when the door body assembly 3 moves between the closed position and the second active position B, the first hinge shaft 4 slides along the third sliding area 13; when the door body assembly 3 moves between the second active position B and the open position, the first hinge shaft 4 slides along the fourth sliding area 14.
