Description

Technical Field

[0001] The present application relates to the technical field of hardware accessories, and in particular to a hinge anti-loosening reinforcement structure. Background Art

[0002] Hinges, also known as hinges, are the main hardware accessories that connect doors. Although most of the current hinge structures can meet the basic opening and closing functions, during long-term use, due to the high opening and closing frequency, environmental changes and other factors, the internal parts of the hinges are prone to wear, resulting in loose structure, which in turn causes problems such as abnormal noise, seriously affecting the user experience.

[0003] Existing technical solutions include but are not limited to increasing the number of screws, improving material properties, etc. For example, the fastening of the hinge can be enhanced by increasing the number of fixing screws, but this method will increase the complexity of installation and may also cause the hinge to be inflexible due to over-tightening; another method is to use more wear-resistant materials, such as stainless steel or alloy materials, which can increase the service life of the hinge, but also increase the cost.

[0004] Although existing technical means can alleviate the problem of loose hinges to a certain extent, problems such as looseness and abnormal noise still exist, resulting in poor experience and low quietness. Summary of the invention

[0005] In order to improve the problem that the existing hinge structure becomes loose when opening and closing, thereby generating abnormal noise, resulting in poor user experience and quietness, the present application provides a hinge anti-loosening reinforcement structure.

[0006] The present application provides a hinge anti-loosening reinforcement structure, which adopts the following technical solutions: A hinge anti-loosening reinforcement structure comprises a hinge body connected to a cabinet body, a hinge ring connected to a cabinet door, and a hinge straight arm, wherein the hinge straight arm is installed on the hinge body, one end of the hinge ring is rotatably connected to the hinge straight arm, and the hinge ring and the hinge straight arm are connected by a connecting piece, and the connecting piece is used to expand the swing angle between the hinge ring and the hinge straight arm and limit the swing angle; A buffer is installed on the hinge body, the buffer is clamped on the hinge body, one end of the buffer is hinged to the connecting member, and the other end is connected to the hinge straight arm; The buffer is connected to the hinge straight arm via a loosening piece, the loosening piece is passed through the buffer, and two ends of the loosening piece pass through the hinge body and are fixedly connected to the hinge straight arm, and the loosening piece is used to reinforce the buffer and prevent it from loosening.

[0007] By adopting the above technical solution, during the process of opening and closing the cabinet door, the hinge ring connected to the cabinet door rotates relative to the hinge body, and the connecting part, as a structural part connecting the hinge ring and the hinge straight arm, also swings relative to the hinge body, thereby supporting the stable rotation of the hinge ring or the stable swinging of the swing end. Then, when the connecting part moves, it will apply a thrust or a pull to the buffer part, and the buffer part will exert its buffering performance, so that the cabinet door can be opened or closed stably and slowly. At this time, the thrust or pull exerted on the buffer part will be transmitted to the loosening part, and the loosening part will stabilize the connection between the buffer part and the hinge straight arm. When the cabinet door is opened and closed, the various structural parts of the hinge are firmly connected without loosening, thereby improving the problem that the existing hinge itself will become loose when opening and closing, thereby generating abnormal noise, resulting in poor experience and quietness.

[0008] Optionally, the hinge straight arm is connected to the hinge body via an adjusting member, and the adjusting member is sequentially disposed on the hinge straight arm and the hinge body, and is rotatably connected to the hinge straight arm and the hinge body respectively; The hinge body is provided with a clamping portion, and one end of the adjusting member is clamped to the clamping portion.

[0009] By adopting the above technical solution, when the straightening arm is combined with the hinge body, the adjusting piece is pre-rotated and screwed into the straightening arm so that one end of the straightening arm passes through the straightening arm, the straightening arm covers the hinge body, the straightening arm is moved so that one end of the adjusting piece is snapped into the snap-in portion, the adjusting portion is rotated so that the straightening arm and the hinge body are pressed tightly together to complete the combination, and the spacing between the straightening arm and the hinge body can be adjusted to adjust the opening and closing angle of the cabinet door, thereby adjusting the closing gap between the cabinet door and the cabinet body, thereby achieving flexible adjustment to cope with the problem of needing to disassemble the hinge and readjust the position of the hinge when the closing gap cannot be adjusted, thereby improving the practicality and convenience of the hinge.

[0010] Optionally, the hinge body is provided with a position adjusting member, the position adjusting member is sequentially passed through the hinge straight arm and the hinge body, and the position adjusting member is rotatably connected to the hinge body; The hinge straight arm is provided with a first position adjusting portion, and the position adjusting member is passed through the first position adjusting portion and is slidably connected with the first position adjusting portion; The hinge body is provided with a second position adjusting portion, and the two ends of the loosening member respectively pass through the second position adjusting portion and are connected to the hinge straight arm.

[0011] By adopting the above technical solution, when the several hinges of the cabinet door are not on the same horizontal line, the connection position of the hinge ring and the cabinet door is also not on the same horizontal line, resulting in an offset between the hinge end of the cabinet door and the connection end of the cabinet body, making the cabinet door unable to be closed or difficult to close. At this time, by rotating the adjusting member and the adjusting member, the straight hinge arm no longer presses against the hinge body, the straight hinge arm is moved, the adjusting member slides along the first adjusting portion, the adjusting member slides along the adjusting portion, and the loosening member slides along the second adjusting portion, so that the hinge end of the cabinet door is parallel to the connection end of the cabinet body or perpendicular to the horizontal ground, thereby improving the applicability and flexibility. The adjustability allows users or construction personnel to easily adjust it, saving time and maintenance costs, and can cope with the problem of reinstallation caused by the failure to adjust the positions of the remaining structural members after the existing hinge body is fixed.

[0012] Optionally, a first resistance portion is provided on the hinge body, the first resistance portion is in contact with the hinge straight arm, and the position adjusting member passes through the first resistance portion and is rotatably connected to the hinge body.

[0013] By adopting the above technical solution, the first resistance part increases the surface friction between the hinge body and the hinge straight arm, which can reduce the noise, door opening and closing shaking and difficulty in opening and closing of the cabinet door caused by looseness of the hinge straight arm and connecting parts during the operation of the hinge, thereby improving the stability of the structure.

[0014] Optionally, the connecting member includes a first connecting portion, a second connecting portion and a biaxial connecting portion, and the biaxial connecting portion is fixedly mounted on the hinge ring; The first connection portion and the second connection portion are respectively hinged to the biaxial connection portion; The first connecting portion is hinged to the hinged straight arm; The second connecting portion is also hinged to the hinge straightening arm and the buffer component respectively.

[0015] By adopting the above technical solution, the first connecting part and the second connecting part are hinged to the hinge ring through a double-axis connecting part. The double-axis connecting part has better stability than the single-axis connecting part. After the single-axis is fixed to the hinge ring, it is inevitable that it will rotate, causing the hinge to become loose and the support stability to be poor. The first connecting part and the second connecting part are hinged to the hinge straight arm and the buffer part respectively, so that the cabinet door can be opened and closed to the desired angle, and the cabinet door can be supported to open and close stably.

[0016] Optionally, an elastic member is provided at the hinged position between the first connection portion and the hinge straight arm, and the elastic member abuts against the second connection portion and the hinge straight arm respectively, and the elastic member is elastic.

[0017] By adopting the above technical solution, an elastic member is installed at the hinge between the first connection part and the hinge straight arm. When the hinge ring drives the first connection part and the second connection part to rotate, the reaction force generated by the elastic member acts on the second connection part and the hinge straight arm, and can cooperate with the buffer member to keep the cabinet door in the closed and open states, thereby achieving stable support.

[0018] Optionally, the buffer member and the second connecting portion are connected via a triangular portion, the triangular portion is hinged to the buffer member and the hinge straight arm respectively, and the triangular portion is slidably connected to the second connecting portion; The second connecting portion has a bending portion, the bending portion has a guide groove, and the triangular portion slides along the guide groove.

[0019] By adopting the above technical solution, when the hinge ring drives the first connecting part and the second connecting part to rotate, the second connecting part drives the bending part to swing, and the output end of the buffer slides along the guide groove, while buffering the thrust or pulling force brought by the hinge ring. The bending part and the guide groove are provided to enable the buffer to be stably connected to the hinge body during output, and to reduce the force exerted on the loosening part, so that the buffer does not loosen when the cabinet door is opened and closed, thereby improving the stability of the hinge.

[0020] Optionally, the loosening member has a second resistance portion, the second resistance portion is located on the surface of the loosening member, and the second resistance portion is used to increase the friction between the loosening member and the buffer member.

[0021] By adopting the above technical solution, the loose fastener is an important component for supporting the buffer. During the operation of the buffer, most of the force generated is dispersed by the loose fastener. By providing a second resistance portion on the surface of the loose fastener, the contact area and contact pressure can be increased, thereby resisting the sliding of the buffer along the axial direction of the loose fastener.

[0022] Optionally, the loosening member has a bent portion, and the bent portion has the function of increasing the extrusion stress between the loosening member and the buffer member.

[0023] By adopting the above technical solution, the loose fixture has a curved portion, which will form a closer contact with the surface of the buffer, increase the contact area and contact pressure, and increase the friction force, thereby resisting the sliding of the buffer along the axial direction of the loose fixture; due to the existence of the curved portion, the loose fixture will generate a greater radial force on the buffer, thereby increasing the extrusion stress between the loose fixture and the buffer, and the increase in the extrusion stress helps to fix the buffer and prevent it from moving in the radial direction.

[0024] Optionally, the hinge ring has a receiving portion, and the receiving portion is used to receive the connecting member and one end of the hinge straight arm.

[0025] By adopting the above technical solution, the accommodating part accommodates the connecting piece and one end of the hinge straight arm, so that some components of the reinforced hinge do not affect the opening and closing of the cabinet door, thereby achieving stable support, while also expanding the adjustable range of the hinge swing angle and improving applicability.

[0026] In summary, this application has the following beneficial effects: 1. The loosening fixture stabilizes the connection between the buffer and the hinge arm. When the cabinet door is opened and closed, the various structural parts of the hinge are firmly connected without loosening. This improves the problem that the existing hinge structure will become loose when opening and closing, causing abnormal noise, resulting in poor experience and quietness.

[0027] 2. By setting an adjustment part and adjusting the distance between the hinge straight arm and the hinge body, the opening and closing angle of the cabinet door can be adjusted, thereby adjusting the closing gap between the cabinet door and the cabinet body, achieving flexible adjustment to cope with the problem of needing to disassemble the hinge and readjust the position of the hinge when the closing gap cannot be adjusted, thereby improving the practicality and convenience of the hinge.

[0028] 3. A positioning member, a first positioning part and a second positioning part are provided. By rotating the positioning member and the adjusting member, the hinge straight arm no longer presses against the hinge body, the hinge straight arm is moved, the positioning member slides along the first positioning part, the adjusting member slides along the adjusting part, and the loosening member slides along the second positioning part, so that the hinge end of the cabinet door is parallel to the connecting end of the cabinet body or perpendicular to the horizontal ground, thereby improving the applicability and flexibility. The adjustability enables users or construction personnel to easily adjust, saving time and maintenance costs, and can cope with the reinstallation problem caused by the failure to adjust the positions of the remaining structural parts after the existing hinge body is fixed.

[0029] 4. The first resistance part is set to increase the surface friction between the hinge body and the hinge straight arm, which can reduce the noise, door opening and closing shaking and door difficulty caused by the looseness of the hinge straight arm and the connecting parts during the operation of the hinge, thereby improving the stability of the structure.

[0030] 5. An elastic member is provided, and the reaction force generated by the elastic member is used to act on the second connecting part and the hinge straight arm, which can cooperate with the buffer member to keep the cabinet door in the closed and open states to achieve stable support.

[0031] 6. By providing the second resistance portion on the surface of the loosening member, the contact area and contact pressure can be increased, thereby resisting the sliding of the buffer member along the axial direction of the loosening member.

[0032] 7. The bent portion of the loose fixture will form a closer contact with the surface of the buffer, increasing the contact area and contact pressure, thereby increasing the friction force and resisting the sliding of the buffer along the axis of the loose fixture. Due to the existence of the bent portion, the loose fixture will generate a greater radial force on the buffer, thereby increasing the extrusion stress between the loose fixture and the buffer. The increase in extrusion stress helps to fix the buffer and prevent it from moving in the radial direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The adjusting member 7 is rotated and screwed into the hinge straight arm 3 in advance so that one end of the adjusting member 7 passes through the hinge straight arm 3. The hinge straight arm 3 is moved so that one end of the adjusting member 7 is clamped into the clamping portion 13.

[0064] The above scheme increases the contact area and contact pressure by setting a second resistance portion 61 on the surface of the loosening fixture 6 to resist the sliding of the buffer 5 along the axial direction of the loosening fixture 6. Then, the middle portion of the loosening fixture 6 is bent, and the loosening fixture 6 generates a greater radial force on the buffer 5 to increase the extrusion stress between the loosening fixture 6 and the buffer 5. The increase in the extrusion stress helps to fix the buffer 5 and prevent it from moving in the radial direction, thereby strengthening the hinge. In addition, the first resistance portion 11, the first connecting portion 41, the second connecting portion 42 and the triangular portion 45 and other structural parts cooperate with each other to further strengthen the hinge and prevent loosening.
