Detailed Implementation

[0019] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] See Figure 1-5 This utility model provides a novel hinge structure, including a hinge cup 1, a hinge arm 2, and a fixed base 4. The hinge cup 1 is used to install on a cabinet door. The hinge arm 2 includes a first hinge arm body 21 and a second hinge arm body 22 arranged front and rear. The hinge cup 1 and the front end of the first hinge arm body 21 are hinged to open and close through a rocker arm assembly 3. The fixed base 4 is located at the bottom of the second hinge arm body 22 and is connected to the second hinge arm body 22. The fixed base 4 is used to install on a cabinet.

[0023] Specifically, the second hinge arm body 22 has an inverted U-shaped structure, and the bottom of both side plates are bent outward to form two first bending plates 221 respectively; preferably, the first bending plates 221 are arranged horizontally; both sides of the fixed base 4 are bent upward to form two second bending plates 41 respectively; preferably, the second bending plates 41 are arranged vertically; wherein, the outer side walls of the two first bending plates 221 abut against the inner side walls of the two second bending plates 41 respectively, thereby achieving the limitation of the two sides of the second hinge arm body 22.

[0024] Therefore, by setting two first bending plates 221 on the hinge arm 2 and two second bending plates 41 on the fixed base 4, and by the abutting cooperation between the two first bending plates 221 and the two second bending plates 41, the two sides of the second hinge arm body 22 can be limited, thereby preventing the hinge arm 2 from swinging to the sides after being subjected to force, ensuring that the cabinet door does not swing, and greatly improving the assembly firmness of the hinge structure.

[0025] In this embodiment, the first hinge arm body 21 and the second hinge arm body 22 are integrally formed.

[0026] More preferably, the first bending plate 221 is provided with a plurality of protrusions 2212 near the edge of the second bending plate 41, and the plurality of protrusions 2212 are arranged at intervals in the left-right direction. Thus, by providing a plurality of protrusions 2212, not only can the contact area between the first bending plate 221 and the second bending plate 41 be increased, thereby improving the contact strength between the two, but at the same time, the protrusions 2212 can also increase the support strength of the first bending plate 221 and prevent its deformation.

[0027] Of course, in other embodiments, the protrusion 2212 can be replaced with a groove, which can achieve the same technical effect, and there is no limitation on it here.

[0028] Furthermore, the hinge structure also includes a decorative cover 7, which covers the fixed base 4 and conceals the second hinge arm body 22 from the fixed base 4. The decorative cover 7 and the second bent plate 41 are assembled and fixed via a snap-fit ​​structure. Specifically, the snap-fit ​​structure includes a snap-fit ​​block 71 and a snap-fit ​​hole 411 that engage with each other. The snap-fit ​​block 71 is located on the two inner side walls of the decorative cover 7, and the snap-fit ​​hole 411 is located on the outer side wall of the second bent plate 41. When the decorative cover 7 is placed on the fixed base 4 until the snap-fit ​​block 71 and the snap-fit ​​hole 411 engage with each other, the decorative cover 7 is assembled and fixed to the fixed base 4.

[0029] Therefore, by providing the decorative cover 7, the second hinge arm body 22 and the fixed base 4 can be concealed, thereby ensuring that the overall appearance of the hinge structure is simpler and improving the aesthetics of the product.

[0030] Of course, it should be noted that in other embodiments, the positions of the card block 71 and the card hole 411 can be interchanged, which can also achieve the same technical effect, and this is not a limitation.

[0031] See also Figure 2 The fixed base 4 has several first mounting holes 42 for fixing to the cabinet, and the first bent plate 221 has clearance holes 2211 that connect to the several first mounting holes 42. Thus, the fixed base 4 can be assembled by passing screws through the first mounting holes 42 and fixing them to the cabinet.

[0032] Among them, several first mounting holes 42 include at least an elongated slotted hole extending in the left-right direction; thus, when the screws are loosened, the fixed base 4 can adjust its left-right position through the elongated slotted hole. Since the second hinge arm body 22 is connected to the fixed base 4, when the left-right position of the fixed base 4 is adjusted, the left-right position of the hinge arm 2 can be adjusted simultaneously, thereby adjusting the left-right position of the cabinet door so that the cabinet door and the cabinet body are flush in the height direction.

[0033] Furthermore, it also includes a first adjusting screw 5 fixedly mounted on the fixed base 4. The second hinge body 22 has a first screw hole 222 through which the first adjusting screw 5 can pass and be threadedly engaged. Thus, when the first adjusting screw 5 is turned, the hinge arm 2 can be moved up and down through the threaded engagement of the first adjusting screw 5 and the first screw hole 222, thereby adjusting the up and down position of the cabinet door and ensuring that the cabinet door can be completely fitted with the cabinet body when closed, avoiding gaps between the two.

[0034] In addition, it includes a second adjusting screw 6 threaded through the fixed base 4. The second hinge body 22 has a third mounting hole 223 through which the second adjusting screw 6 can pass. The third mounting hole 223 extends in the front-back direction. The hinge 2 can adjust its front-back position through the third mounting hole 223. When the second adjusting screw 6 is turned, the second adjusting screw 6 can move up and down through the threaded engagement between the second adjusting screw 6 and the fixed base 4, thereby driving the second hinge body 22 to press against or move away from the fixed base 4.

[0035] Therefore, when the second adjusting screw 6 is rotated to press the second hinge arm body 22 onto the fixed base 4, the assembly and fixation between the two can be achieved; when the second adjusting screw 6 is rotated to loosen the second hinge arm body 22, the second hinge arm body 22 is in an active state, and the second hinge arm body 22 can adjust its front and rear positions through the third mounting hole 223, thereby adjusting the left and right positions of the cabinet door to ensure that both the left and right sides of the cabinet door are flush with the cabinet body.

[0036] In this embodiment, the fixed base 4 has a second screw hole 44 through which the second adjusting screw 6 can pass and be screwed.

[0037] In this embodiment, the fixed base 4 is provided with a second mounting hole 43 through which the first adjusting screw 5 can pass. The second mounting hole 43 extends in the front-back direction to prevent interference when the hinge arm 2 moves in the front-back direction.

[0038] Of course, in order to improve the connection between the second hinge arm body 22 and the fixed base 4, the top wall of the fixed base 4 is provided with a first toothed portion 45 near the second adjusting screw 6, and the bottom wall of the second hinge arm body 22 is provided with a second toothed portion 224 near the third mounting hole 223; wherein, when the second adjusting screw 6 is turned to drive the second hinge arm body 22 to be pressed and fixed to the fixed base 4, the first toothed portion 45 and the second toothed portion 224 are engaged.

[0039] Therefore, the snap-fit ​​engagement between the first toothed portion 45 and the second toothed portion 224 can prevent misalignment between them, thereby improving the connection strength between them.

[0040] In summary, the present invention provides a novel hinge structure in which the bottom of both side plates of the second hinge arm body 22 are bent outward to form two first bending plates 221, and both sides of the fixed base 4 are bent upward to form two second bending plates 41. The outer side walls of the two first bending plates 221 abut against the inner side walls of the two second bending plates 41. This arrangement limits the movement of both sides of the second hinge arm body 22, thereby preventing the hinge arm 2 from swaying to both sides after being subjected to force, ensuring that the cabinet door does not sway, and greatly improving the assembly firmness of the hinge structure.
