Description

Hinge structure and cabinet

technical field

The utility model relates to the field of cabinet production, in particular to a hinge structure and a cabinet adopting the hinge structure.

Background technique

The doors and cabinets of common cabinets are connected by a hinge structure. In actual production, the hinge structure generally uses common external hinges or internal hinges. However, as shown in FIG. 1 , after the cabinet door is connected to the cabinet body through the external hinge, the external hinge will protrude from the side of the cabinet, making the joint visible and affecting the overall appearance of the cabinet. And the cost of using the outer hinge is relatively high, and there are certain potential safety hazards. As shown in Figure 2, after the cabinet door and the cabinet body are connected by the inner hinge, when the cabinet door is closed, the gap between the cabinet door and the cabinet body at the joint is relatively large, which makes the airtightness of the entire cabinet poor. And installing the inner hinge generally needs to cut off the folded edge on the cabinet door for the installation of the inner hinge, thereby reducing the self-strength of the cabinet door.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is described in detail with reference to the accompanying drawings.

Fig. 3 shows a hinge structure in the present invention, which can be used to hinge the cabinet door 10 and the cabinet body 20 of the cabinet. The cabinet is a common air-conditioning cabinet, of course, the cabinet can also have other uses.

Fig. 3 is a structural schematic diagram of the hinge structure in an embodiment of the present invention. As shown in FIG. 3 , the hinge structure includes a first hinge seat 31 , a second hinge seat 32 and a mandrel (not shown). The first hinge seat 31 includes a first connecting portion 311 for screwing and fixing with the cabinet door 10 , and a second connecting portion 312 for passing through the mandrel. The second hinge base 32 includes a third connecting portion 321 for screwing and fixing with the cabinet body 20 , and a fourth connecting portion 322 for passing through the mandrel. And the first connecting portion 311 is adapted to the groove 11 on the cabinet door 10 for installing the first hinge seat 31 .

Specifically, the shape and thickness of the first connecting portion 311 are adapted to the groove 11 so as to facilitate the embedded installation of the first hinge seat 31 . Generally, the cross-sectional shape of the groove 11 can be an inverted trapezoid as shown in FIG. 3 , and the angle between the slope of the groove 11 and the bottom surface of the groove is 135°. The groove 11 of this specific shape can make the transition of the whole door panel natural and beautiful, and facilitate the installation and maintenance of the hinge structure. Of course, the shape of the groove 11 can be processed according to the actual situation, and its specific shape is diverse, and its cross-sectional shape being an inverted trapezoid is only one of the technical solutions of the present invention.

To sum up, the first connecting portion 311 of the novel hinge structure is adapted to the groove 11 on the cabinet door 10, so that the hinge structure can be installed in a simple embedded manner. Therefore, the hinge structure is simple in structure, low in cost and easy to use.

Further, as shown in FIG. 3 , the first connecting portion 311 and the third connecting portion 321 are arranged at an angle. And the angle between the first connecting portion 311 and the third connecting portion 321 is 0˜180°. For example, the included angle between the first connecting portion 311 and the third connecting portion 321 in FIG. 3 is 180°. Then the first connecting part 311 and the third connecting part 321 arranged at an angle make the degree of freedom of opening and closing between the cabinet door 10 hinged by the hinge structure and the cabinet body 20 high, specifically, the cabinet door 10 can be opened relative to the cabinet body. The body 20 opens 180°.
