Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically an adjustment mechanism for hinges. Background Technology

[0002] Hinges, also known as hinges, are commonly used to connect door panels and cabinet mechanisms, allowing relative rotation between the two.

[0003] A hinge typically consists of a hinge cup, a hinge arm, and a base. The hinge cup connects to the door, the base connects to the cabinet, and the hinge arm connects the hinge cup and the base. After installation, the hinge often requires adjustment in height, forward / backward, and left / right directions due to the precision of the mounting holes, to achieve the best opening effect.

[0004] Taking hinges that can be adjusted vertically (relative to the ground) as an example, most of their bases have an adjustment function. Examples include: CN202011360020.1, CN202320159256.1, and CN202411796142.3. The base in these designs generally consists of a fixed base and a movable base. By adjusting the eccentric rivet and guide components, the movable base moves relative to the fixed base, thus achieving the vertical adjustment function of the door panel. However, because the movable base needs to bear the weight of the door panel, under the action of the door panel's gravity and external forces such as vibration, the eccentric rivet adjustment structure cannot prevent the movable base from sliding down.

[0005] To address this, the current solution is to increase the riveting force of the rivets, thereby increasing the rotational friction of the eccentric rivets to reduce the self-slippage of the movable seat. However, the effect is obviously limited. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustment mechanism for hinges that is simple in structure, precise in adjustment, flexible in operation, and effectively solves the problem that the hinge product base does not have a counter-rotating motion during adjustment, thereby improving the user experience.

[0007] The purpose of this invention is achieved as follows: an adjustment mechanism for a hinge includes a fixed seat assembled with a cabinet and a movable seat assembled with a hinge body. The movable seat is slidably connected to the fixed seat, and an adjustment device with a backstop function is provided between the movable seat and the fixed seat. The adjustment device includes an adjustment pin and a threaded hole. The adjustment pin is rotatably connected to the movable seat. The fixed seat is provided with a threaded hole that drives the movable seat to move back and forth as the adjustment pin rotates. The threaded hole is transversely perpendicular to the sliding direction of the movable seat and is located at the bottom of the fixed seat. The adjustment pin passes through the threaded hole and engages with the threaded hole.

[0008] Based on the above optimization, the two sides of the movable seat are respectively adapted to the countersunk hole and the riveting hole for positioning and rotating the adjusting pin. One end of the adjusting pin is limited and rotatably connected to the countersunk hole, and the other end of the adjusting pin passes through the threaded hole and is rotatably connected to the riveting hole.

[0009] Based on the above optimization, the threaded hole is set as a circular threaded hole for the adjustment pin to move, and the diameter of the circular threaded hole is larger than the diameter of the adjustment pin.

[0010] Based on the above optimization, the threaded hole is set as an elliptical hole for the adjustment pin to move.

[0011] Based on the above optimization, the movable seat is provided with a guide pin for limiting the direction of movement, and the fixed seat is provided with a guide hole for adapting to the sliding of the guide pin.

[0012] Based on the above optimization, the guide holes are parallel to the threaded holes and are opened on both sides of the threaded holes, and the guide pins are slidably connected in the guide holes.

[0013] The advantages of this invention are as follows: The adjusting pin and the threaded hole engage in a meshing manner. When the adjusting pin is rotated, the threads of the adjusting pin move along the threads in the threaded hole, causing the movable seat to move onto the fixed seat. Because the threaded hole is perpendicular to the sliding direction of the movable seat, the interaction pressure angle between the adjusting pin and the threaded hole is small. This results in a small displacement component generated by gravity, vibration, impact, or other external forces acting on the two, which is insufficient to overcome friction and produce displacement. Therefore, the movement of the movable seat can only be controlled by the adjusting component, and other external forces acting on the movable seat cannot move it, achieving a backstop effect. The structure is simple, the adjustment is precise, the operation is flexible, and it effectively solves the problem of no backstop movement when adjusting the base of hinge products, improving the user experience.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] According to the appendix Figures 1 to 4As shown, the hinge adjustment mechanism of this utility model includes a fixed seat 1 assembled with the cabinet body and a movable seat 2 assembled with the hinge body. The movable seat 2 is slidably connected to the fixed seat 1, and an adjustment device with anti-reverse function is provided between the movable seat 2 and the fixed seat 1. The adjustment device includes an adjustment pin 3 and a threaded hole 4. The adjustment pin 3 is rotatably connected to the movable seat 2. The fixed seat 1 is provided with a threaded hole 4 that drives the movable seat 2 to move back and forth as the adjustment pin 3 rotates. The threaded hole 4 is transversely perpendicular to the sliding direction of the movable seat 2 and is located at the bottom of the fixed seat 1. The adjustment pin 3 passes through the threaded hole 4 and engages with the threaded hole 4.

[0020] The adjusting pin 3 engages with the threaded hole 4. When the adjusting pin 3 is rotated, the threads of the adjusting pin 3 move along the threads in the threaded hole 4, causing the movable seat 2 to move onto the fixed seat 1. Because the threaded hole 4 is perpendicular to the sliding direction of the movable seat 2, the interaction pressure angle between the threads of the adjusting pin 3 and the threaded hole 4 is small. This results in a small displacement component generated by gravity, vibration, impact, or other external forces acting on the two, which is insufficient to overcome friction and produce displacement. Therefore, the movement of the movable seat 2 can only be controlled by the adjusting component, and other external forces acting on the movable seat 2 cannot move it, achieving a backstop effect. The structure is simple, the adjustment is precise, the operation is flexible, and it effectively solves the problem of the lack of backstop movement during adjustment of the hinge product base, improving the user experience.

[0021] Reference Figures 1 to 4 As shown in the figure, in further detail, the movable seat 2 is provided with a guide pin 7 for limiting the direction of movement, and the fixed seat 1 is provided with a guide hole 8 for adapting to the sliding of the guide pin 7.

[0022] Furthermore, the guide holes 8 are parallel to the threaded holes 4 and are opened on both sides of the threaded holes 4, and the guide pins 7 are slidably connected in the guide holes 8.

[0023] By using guide pin 7 and adjusting pin 3 arranged parallel to each other, when adjusting pin 3 is rotated, the thread of adjusting pin 3 moves along the thread of threaded hole 4, causing movable seat 2 to move in the direction of guide pin 7. Furthermore, with the structural cooperation of guide hole 8 and guide pin 7, movable seat 2 can ultimately only be controlled by adjusting pin 3 and move in the direction of guide pin 7. This simplifies the structure, improves adjustment accuracy, and ensures product quality.

[0024] Reference Figures 1 to 4 As shown, in further detail, the two sides of the movable seat 2 are respectively fitted with countersunk holes 5 and riveting holes 6 for positioning and rotating the adjusting pin 3. One end of the adjusting pin 3 is rotatably connected to the countersunk hole 5, and the other end of the adjusting pin 3 passes through the threaded hole 4 and is rotatably connected to the riveting hole 6.

[0025] The threaded hole 4 is a circular threaded hole for the adjustment pin 3 to move, and the diameter of the circular threaded hole is larger than the diameter of the adjustment pin 3.

[0026] Alternatively, the threaded hole 4 may be configured as an elliptical hole for the adjustment pin 3 to move.

[0027] The use of this structure, with the threaded hole 4 and adjusting pin 3 working together, allows for flexible operation, further improves adjustment accuracy, enhances the anti-reverse effect, ensures safety and reliability, and increases the user experience.

[0028] The above specific embodiments are only specific implementations of the present utility model with better effects. Any structure that is the same as or equivalent to the adjustment mechanism for the hinge of the present utility model is within the protection scope of the present utility model.
