Description

Technical Field

[0001] This utility model relates to the technical field of hardware accessories, specifically to a hinge that is stable to install. Background Technology

[0002] See Figure 1 Recessed hinges (also known as top and bottom hinges) consist of a hinge shell, which is fixed by embedding into a mounting slot in the cabinet. In traditional structures, the front face of the hinge shell has only a single fixing hole, which mates with a corresponding screw hole in the mounting slot, using a single screw to connect the hinge shell to the cabinet. This single-point fixing method has a significant drawback: during long-term use with repeated opening and closing of the door, the hinge shell is prone to loosening due to unidirectional force, leading to axial wobble of the hinge shell relative to the cabinet. This unintended displacement causes an angle between the hinge shell and the cabinet, severely affecting the movement accuracy and structural stability of the hinge system. Utility Model Content

[0003] This invention proposes a stable hinge with a first and a second fixing structure on the hinge shell, forming a two-point fixing connection between the hinge shell and the fixing unit. This effectively prevents loosening problems caused by traditional single-screw fixing methods. Because the door exerts periodic tensile forces on the hinge during repeated opening and closing, traditional single-point fixing structures are prone to uneven stress distribution, causing the hinge shell to shift back and forth within the fixing unit, thus affecting the stability of the hinge system. The two-point fixing method used in this solution provides more balanced support for the hinge shell under stress, avoiding swaying caused by unidirectional stress concentration. Furthermore, the two-point fixing structure enhances the overall rigidity between the hinge shell and the fixing unit, thereby extending the hinge's service life.

[0004] A hinge designed for this purpose with stable installation includes a hinge cup and a hinge housing that is hinged to the hinge cup and mounted on a fixed unit.

[0005] The hinge shell is provided with a first fixing structure and a second fixing structure. The hinge shell and the fixing unit are connected by a double-point fixing structure through the first fixing structure and the second fixing structure, forming a double-point anti-loosening fixing mechanism to prevent relative displacement between the hinge shell and the fixing unit.

[0006] Both the first and second fixing structures are equipped with fasteners, and the hinge shell and the fixing unit are rigidly fixedly connected through the fixing structures and fasteners.

[0007] The first fixing structure and the second fixing structure are arranged at left and right intervals along the length direction of the hinge shell.

[0008] The first fixing structure and the second fixing structure are arranged at intervals along the width direction of the hinge shell.

[0009] The first fixing structure is located at the front end of the hinge shell, and the second fixing structure is located at the upper part of the hinge shell, and is located close to the rear end of the hinge shell.

[0010] The hinge shell includes an upper shell and a lower shell;

[0011] The second fixing structure is located on the upper part of the upper shell;

[0012] The first fixing structure is disposed on the front end face of the lower shell.

[0013] The fixing unit is provided with a mounting groove for mounting the hinge shell;

[0014] The fixing unit is provided with a first mounting structure corresponding to the first fixing structure;

[0015] The fixing unit is provided with a second mounting structure corresponding to the second fixing structure.

[0016] A connecting arm assembly is provided between the hinge cup and the hinge shell. The first end of the connecting arm assembly is fixedly connected to the hinge cup, and the second end of the connecting arm assembly is rotatably connected to the hinge shell. The hinge cup and the hinge shell are hinged together by the connecting arm assembly.

[0017] The hinge cup is provided with a fixing component that is fixedly connected to the first end of the connecting arm assembly;

[0018] The fixed assembly is provided with an upper and lower adjustment block, and the hinge cup is provided with an upper and lower adjustment component that is threadedly connected to the upper and lower adjustment block.

[0019] When the up-down adjustment component rotates, it drives the hinge cup and the up-down adjustment block to move up and down relative to the fixed assembly, so as to adjust the relative up-down position between the hinge cup and the hinge shell.

[0020] The inner cavity of the hinge cup and the fixed assembly are provided with an upper and lower sliding gap for the hinge cup to move up and down during the adjustment process;

[0021] An inclined mating surface is provided between the upper and lower adjusting block and the fixed assembly. When the upper and lower adjusting component rotates, the upper and lower adjusting block moves up and down along the inclined mating surface.

[0022] The hinge housing is provided with a connecting block that is rotatably connected to the second end of the connecting arm assembly, and an adjusting seat that is movably connected to the connecting block;

[0023] A positioning movable connection component is provided between the connecting block and the adjusting seat to make the connecting block and the adjusting seat movably connected in a positioning manner. The adjusting seat is provided with front and rear adjusting parts, and the front and rear adjusting parts are threadedly connected to the adjusting seat.

[0024] When the front and rear adjustment component rotates, the adjustment seat drives the connecting block to move back and forth within the hinge housing to adjust the relative front and rear positions between the hinge cup and the hinge housing.

[0025] The adjusting seat is provided with a movable block and a left and right adjusting component that is threadedly connected to the movable block. The movable block is provided with an inclined surface, and the connecting block is provided with an inclined groove. The inclined surface of the movable block is installed in the inclined groove of the connecting block.

[0026] When the left and right adjustment component rotates, it drives the movable block to move back and forth in the adjustment seat, so as to drive the connecting block to slide left and right on the adjustment seat through the cooperation of the inclined surface and the inclined groove. The connecting block slides left and right on the adjustment seat along the direction of the positioning movable connection component, so as to adjust the left and right relative position between the hinge cup and the hinge shell.

[0027] The positioning movable connection component includes a protrusion disposed on the adjustment seat and a transverse groove disposed laterally on the connection block;

[0028] The hinge housing is provided with a vertical groove that cooperates with the protrusion to constrain the adjusting seat to move only back and forth. The upper part of the protrusion passes through the horizontal groove and is installed in the vertical groove.

[0029] The beneficial technical effects of this utility model are as follows:

[0030] The hinge shell features both a first and a second fixing structure, creating a two-point connection between the hinge shell and the fixing unit. This effectively prevents loosening issues caused by traditional single-screw fixing methods. Because the door exerts periodic tensile forces on the hinge during repeated opening and closing, traditional single-point fixing structures are prone to uneven stress distribution, leading to back-and-forth displacement of the hinge shell within the fixing unit and affecting the stability of the hinge system. The two-point fixing method used in this solution provides more balanced support to the hinge shell under stress, avoiding swaying caused by unidirectional stress concentration. Furthermore, the two-point fixing structure enhances the overall rigidity between the hinge shell and the fixing unit, thereby extending the hinge's lifespan. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0039] See Figures 2-7 A hinge with stable installation includes a hinge cup 1 and a hinge shell 2 that is hinged to the hinge cup 1 and mounted on a fixed unit 3;

[0040] The hinge shell 2 is provided with a first fixing structure 201 and a second fixing structure 202. The hinge shell 2 and the fixing unit 3 are connected by a double-point fixing structure through the first fixing structure 201 and the second fixing structure 202, forming a double-point anti-loosening fixing mechanism to prevent relative displacement between the hinge shell 2 and the fixing unit 3.

[0041] Fixed unit 3 is a cabinet.

[0042] The hinge shell 2 is equipped with a first fixing structure 201 and a second fixing structure 202, forming a two-point fixing connection between the hinge shell 2 and the fixing unit 3, effectively preventing loosening problems caused by traditional single-screw fixing methods. Because the door body applies periodic tensile forces to the hinge during repeated opening and closing, traditional single-point fixing structures are prone to uneven force distribution, causing the hinge shell 2 to shift back and forth within the fixing unit 3, thus affecting the stability of the hinge system. The two-point fixing method used in this solution provides more balanced support for the hinge shell 2 under stress, avoiding swaying caused by unidirectional stress concentration. Furthermore, the two-point fixing structure enhances the overall rigidity between the hinge shell 2 and the fixing unit 3, thereby extending the hinge's service life.

[0043] Both the first fixing structure 201 and the second fixing structure 202 are provided with fasteners 203, and the hinge shell 2 and the fixing unit 3 are rigidly fixedly connected through the fixing structure and the fasteners 203.

[0044] Both the first fixing structure 201 and the second fixing structure 202 are equipped with fasteners 203, forming a rigid connection between the hinge shell 2 and the fixing unit 3, further improving the stability of the hinge. Traditional single-screw fixing methods only provide limited torsional resistance, while this solution, through the rigid connection of double fasteners 203, evenly distributes the torque borne by the hinge shell 2 during door opening and closing, avoiding connection failure caused by excessive local stress. Furthermore, the fasteners 203 can be high-strength screws or bolts to ensure sufficient tensile strength at the fixing points, thereby maintaining a stable connection during long-term use and preventing displacement of the hinge shell 2 due to vibration or impact.

[0045] Fastener 203 is a fastening screw.

[0046] The first fixing structure 201 and the second fixing structure 202 are arranged at left and right intervals along the length direction of the hinge shell 2.

[0047] The first fixing structure 201 and the second fixing structure 202 are arranged at intervals along the width direction of the hinge shell 2.

[0048] This layout maximizes the anti-sway effect of dual-point fixing, ensuring that the two fixing points of the hinge shell 2 provide complementary support when subjected to the opening and closing force of the door, effectively suppressing the tendency of the hinge shell 2 to shift in the front-back or left-right directions. Compared to traditional single-point fixing, this arrangement significantly improves the hinge's torsional resistance, ensuring that the hinge shell 2 maintains a stable connection with the fixing unit 3 during door movement, avoiding loosening or tilting problems caused by long-term use.

[0049] The first fixing structure 201 is located at the front end of the hinge shell 2, and the second fixing structure 202 is located at the upper part of the hinge shell 2, and the second fixing structure 202 is located close to the rear end of the hinge shell 2.

[0050] The hinge shell 2 includes an upper shell 204 and a lower shell 205;

[0051] The second fixing structure 202 is disposed on the upper part of the upper shell 204;

[0052] The first fixing structure 201 is disposed on the front end face of the lower shell 205.

[0053] The fixing unit 3 is provided with a mounting groove 301 for mounting the hinge shell 2;

[0054] The fixing unit 3 is provided with a first mounting structure 302 corresponding to the first fixing structure 201;

[0055] The fixing unit 3 is provided with a second mounting structure 303 corresponding to the second fixing structure 202.

[0056] A connecting arm assembly 4 is provided between the hinge cup 1 and the hinge shell 2. The first end of the connecting arm assembly 4 is fixedly connected to the hinge cup 1, and the second end of the connecting arm assembly 4 is rotatably connected to the hinge shell 2. The hinge cup 1 and the hinge shell 2 are hinged together by the connecting arm assembly 4.

[0057] The hinge cup 1 is provided with a fixing component 101 that is fixedly connected to the first end of the connecting arm assembly 4;

[0058] The fixed assembly 101 is provided with an up-down adjustment block 102, and the hinge cup 1 is provided with an up-down adjustment component 103 that is threadedly connected to the up-down adjustment block 102.

[0059] When the up-down adjustment member 103 rotates, it drives the hinge cup 1 and the up-down adjustment block 102 to move up and down relative to the fixed assembly 101, so as to adjust the relative up-down position between the hinge cup 1 and the hinge shell 2.

[0060] The design of the upper and lower adjustment block 102 and the upper and lower adjustment component 103 allows the hinge cup 1 to be precisely adjusted in vertical displacement relative to the fixed assembly 101. This adjustment mechanism can compensate for installation errors between the door and the cabinet.

[0061] The inner cavity of the hinge cup 1 and the fixed assembly 101 are provided with an upper and lower sliding gap 104 for the hinge cup 1 to move up and down during the adjustment process.

[0062] An inclined mating surface 105 is provided between the upper and lower adjusting block 102 and the fixed assembly 101. When the upper and lower adjusting member 103 rotates, the upper and lower adjusting block 102 moves up and down along the inclined mating surface 105.

[0063] A sliding gap 104 is provided between the inner cavity of the hinge cup 1 and the fixed assembly 101, and an inclined mating surface 105 is provided between the upper and lower adjusting block 102 and the fixed assembly 101, so that the upper and lower adjusting block 102 slides along the inclined surface when the upper and lower adjusting member 103 rotates, thereby realizing the smooth lifting and lowering of the hinge cup 1 and effectively preventing the door body from sagging after adjustment.

[0064] The connecting arm assembly 4 includes an outer rocker arm and an inner rocker arm.

[0065] The fixing assembly 101 includes a first connecting block that slides up and down with the upper and lower adjusting block 102 at an angle, and a second connecting block that is fixedly connected to the connecting arm assembly 4. The first connecting block is located on the upper part of the second connecting block, and the first connecting block and the second connecting block are fixedly connected by screws.

[0066] The hinge housing 2 is provided with a connecting block 206 that is rotatably connected to the second end of the connecting arm assembly 4, and an adjusting seat 207 that is movably connected to the connecting block 206.

[0067] A positioning movable connection component 208 is provided between the connecting block 206 and the adjusting seat 207 so that the connecting block 206 and the adjusting seat 207 are positioned and movablely connected. The adjusting seat 207 is provided with a front and rear adjusting component 209, which is threadedly connected to the adjusting seat 207.

[0068] When the front and rear adjustment member 209 rotates, the adjustment seat 207 drives the connecting block 206 to move back and forth inside the hinge shell 2 to adjust the relative front and rear position between the hinge cup 1 and the hinge shell 2.

[0069] The adjusting seat 207 is provided with a movable block 212 and a left and right adjusting member 211 threadedly connected to the movable block 212. The movable block 212 is provided with an inclined surface 213, and the connecting block 206 is provided with an inclined groove 214. The inclined surface 213 of the movable block 212 is installed in the inclined groove 214 of the connecting block 206.

[0070] When the left and right adjustment member 211 rotates, it drives the movable block 212 to move back and forth in the adjustment seat 207, so that the connecting block 206 can slide left and right on the adjustment seat 207 through the cooperation of the inclined surface 213 and the inclined groove 214. The connecting block 206 slides left and right on the adjustment seat 207 along the direction of the positioning movable connection component 208, so as to adjust the left and right relative position between the hinge cup 1 and the hinge shell 2.

[0071] The positioning movable connection assembly 208 includes a protrusion 215 disposed on the adjustment seat 207 and a transverse groove 216 disposed laterally on the connection block 206;

[0072] The hinge housing 2 is provided with a vertical groove 217 that cooperates with the protrusion 215 to constrain the adjusting seat 207 to move only back and forth. The upper part of the protrusion 215 passes through the horizontal groove 216 and is installed in the vertical groove 217.

[0073] Due to manufacturing errors, some assembly errors may occur during installation. To resolve these assembly errors, left-right adjustment component 211, front-back adjustment component 209, and up-down adjustment component 103 are provided.

[0074] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
