Description

Technical Field

[0001] The utility model relates to a hinge, in particular to a hinge with adjustable buffering force. Background Art

[0002] A hinge is a mechanical device used to connect two solid bodies and allow them to rotate relative to each other. A buffer hinge is a type of hinge, also known as a damping hinge. A door leaf with a buffer hinge can close slowly by itself when closing the door, reducing the impact force. Even if you use force to close the door, there will be no loud collision, ensuring the safety of the door body. A traditional buffer hinge is mainly composed of a hinge cup, a connecting rod, a hinge arm and a damper. When the hinge arm swings to close, the torsion spring hooks the cylinder of the damper and moves it, causing the telescopic rod of the damper to contract, thereby achieving a buffer for the hinge. The hinges on the market are of conventional design, that is, the starting and ending points of their buffering are fixed, that is, a hinge has only one buffering effect. However, in different application scenarios, different buffering strengths may be required. For example, a heavier door body may require a stronger buffering effect to prevent damage caused by its rapid closing, while a lighter door body requires a lighter buffering effect to maintain smoothness during the closing process. Hinges with fixed buffering effects cannot meet the above-mentioned multi-type requirements. The applicability of the hinge is limited and cannot be optimized according to demand. Therefore, there is an urgent need to propose a hinge with adjustable buffering strength. Utility Model Content

[0021] The utility model is further described in detail below with reference to the accompanying drawings. A hinge with adjustable buffering force, comprising a main arm body 1 and a hinge cup 2, the main arm body 1 and the hinge cup 2 are hingedly connected as a whole through an upper connecting rod 11 and a lower connecting rod 10, characterized in that: a buffer 3 is installed in the main arm body 1, one end of the buffer 3 is hinged to the lower connecting rod 10, and the other end of the buffer 3 is connected to the main arm body 1 through an adjustment bracket 4; one end of the adjustment bracket 4 is hinged to the buffer 3, and the other end is connected to an eccentric nail 6 rotatably installed on the main arm body 1 through a riveting hole 44 provided in the main body, and when the eccentric nail 6 rotates, it pushes the adjustment bracket 4 and the main arm body 1 to generate relative displacement.

[0022] The adjusting bracket 4 comprises a mounting plate 41 and clamping plates 42 extending outwardly from two sides thereof, and the buffer 3 is clamped and mounted in the two clamping plates 42 .

[0023] The clamping plate 42 is provided with an adjustment hole 43 , and the latch 5 passes through the adjustment hole 43 in sequence and is hinged to the buffer 3 , so that the buffer 3 can swing along the latch 5 .

[0024] The riveting holes 44 are arranged on the mounting plate 41 .

[0025] The main arm body 1 is provided with an adjustment slot 13 , and the eccentric nail 6 passes through the adjustment slot 13 and is rotatably hinged with the adjustment bracket 4 .

[0026] The adjusting groove 13 is configured as a waist-shaped groove, and the waist-shaped groove is configured to penetrate the main arm body 1 .

[0027] The eccentric nail 6 includes a screw head part 61 and a rotating shaft part 62 coaxial therewith, an eccentric shaft 63 extends downward from the end surface of the rotating shaft part 62, and the axis of the eccentric shaft 63 is offset from the axis of the screw head part 61 and the rotating shaft part 62. The rotating shaft part 62 is located in the adjustment slot 13 and rotates.

[0028] The adjustment hole 43 is configured as a round hole.

[0029] The adjustment hole 43 is configured as a waist-shaped groove, and the waist-shaped groove is configured to extend laterally along the clamping plate 42 .

[0030] Working principle: The hinge includes a main arm body and a hinge cup, wherein a buffer is installed inside the main arm body, one end of the buffer is hinged to the lower connecting rod, and the other end is connected to the main arm body through an adjustment bracket. The adjustment bracket adjusts the buffer starting point and buffer end point of the buffer, so that the buffer effect of the buffer is adjustable. The same hinge can be adapted for use in different application scenarios, with strong flexibility and versatility.

[0031] It should be noted that an adjustment groove is provided in the main arm body, and the adjustment groove is set in a waist-shaped groove, and the eccentric nail can rotate and slide in the waist-shaped groove. The eccentric nail is used to pass through the adjustment groove in turn, and continues to extend downward until the eccentric shaft of the eccentric nail is axially connected with the riveting hole, wherein the rotating shaft part of the eccentric nail is clamped in the adjustment groove, and the screw head part is clamped on the top of the adjustment groove, limiting the axial displacement of the eccentric nail. When it is necessary to adjust the buffering effect of the buffer, the eccentric nail is rotated by the screw head part using a special tool, and the rotating shaft part slides forward and backward along the direction of the adjustment groove, and the adjustment bracket is synchronously driven to slide left and right through the eccentric shaft, adjusting the relative displacement of the adjustment bracket in the main arm body, thereby changing the buffering starting point and end point of the buffer. The design of the eccentric shaft and the sliding adjustment limited to the adjustment groove ensure the accuracy and stability during the adjustment process, and ensure the long-term stable performance of the hinge.

[0032] Among them, the adjustment bracket includes a mounting plate and a clamping plate extending outward from both sides of the mounting plate. An adjustment hole is opened through the clamping plate. The adjustment hole is hinged to the buffer by using a pin that passes through the adjustment hole in turn. The buffer can swing along the pin, further increasing the flexibility of adjusting the buffering effect.

[0033] Embodiment 1: The above-mentioned adjustment hole can be set as a round hole. In the compression hinge, the buffering starting point of the buffer body can be directly adjusted by rotating the eccentric nail, thereby adjusting the buffering effect of the buffer.

[0034] Embodiment 2: The above-mentioned adjustment hole can be set as a waist-shaped groove, which is extended laterally along the clamping plate. The buffering stroke of the buffer is adjusted by rotating the eccentric nail, so that the buffering effect of the buffer can be adjusted.

[0035] In the traditional fixed buffer effect hinge, an adjustment bracket is added to adjust the buffer effect of the buffer. It has a simple structure and is convenient and easy to operate. By changing the buffer effect, the resistance of the hinge when closing the door body can be changed. It is suitable for doors of different weights and sizes. In lightweight cabinet doors or heavier furniture doors, users can adjust according to different application scenarios to ensure the smooth and quiet closing of the door body, effectively extending the service life of the door body.

[0036] In addition, after long-term use, the hinge will produce a certain inertia, resulting in a reduction in its buffering effect. At this time, the buffering effect can also be adjusted so that the hinge is always in the best working condition and its service life is extended. Therefore, it can be widely promoted.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
