Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge with a damping buffer installed in a hinge cup. Background Art

[0002] Hinges can be roughly divided into two types according to the installation method of the damping buffer (also known as a damper). One type is that the damper is installed in a hinge seat fixed to the cabinet wall, and the other type is installed in a hinge cup fixed to the cabinet door. Usually, the buffer of the hinge starts to buffer when the cabinet door is closed to a certain angle, and the angle from when the damper starts to buffer to when the cabinet door is completely closed is defined as the buffer angle. In fact, in some cases, people hope that the buffer angle of the hinge can be adjusted. It is not difficult to know that to adjust the buffer angle of the hinge, only the telescopic stroke of the damper needs to be adjusted. During the actual R & D process, people found that to adjust the telescopic stroke of the damper, it is only convenient to operate when the cabinet door is in the open state, and at this time the damper is in the extended state. If the stroke of the damper is adjusted to be shortened at this time, it is very difficult to compress the damper through a conventional adjustment mechanism. The reason is that as a damper of a hinge, its damping force is very large, especially for a heavy-duty hinge, its damping force is even greater. It is difficult to operate with a conventional tool, and a large adjustment force needs to be continuously applied to compress the damper, making it impossible to achieve easy adjustment, which obviously violates people's usual adjustment operation habits. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an adjustable buffer hinge that is convenient to adjust.

[0004] The technical solution adopted to solve the above technical problem: An adjustable buffer hinge includes a hinge cup, a hinge seat, a hinge arm hinged between the hinge cup and the hinge seat, a cam fixed to the end of the hinge axis of the hinge arm and the hinge cup, and a damper that abuts against the cam to buffer the closing of the hinge cup. The characteristics are as follows: The damper is a non-self-resetting damper and is installed on the outer side of the hinge cup. Corresponding to this side, the cam is fixed to the end of the hinge axis on this side. A slider that slides in the damping telescopic direction and a compression spring are also installed on the outer side of the hinge cup. A stop block is formed on the cylinder body of the damper. The slider abuts against the damper retracting direction side of the stop block, and the compression spring abuts against the damper retracting direction side of the slider. A relaxation eccentric screw is installed on the top of the hinge cup, and the eccentric part of the relaxation eccentric screw abuts against the damper extending direction side of the slider.

[0005] On the above basis, a cavity body for installing the compression spring, the slider, and the damper is fixed to the outer side of the hinge cup.

[0006] Beneficial effects brought by the present utility model: Since the damper of the hinge of the present utility model adopts a non-self-resetting damper, and the return spring of the damper adopts an external compression spring, then adjusting the telescopic stroke of the compression spring can adjust the telescopic stroke of the damper. At the same time, the compression spring abuts against the cylinder block of the damper through a slider. At this time, the compression spring can be adjusted by adjusting the position of the slider. The adjustment of the slider position is adjusted by a locknut eccentric screw. By rotating the locknut eccentric screw, the compression of the compression spring can be quickly adjusted, and the force required to compress the compression spring is much smaller than the force required to compress the damper, and the force to compress the compression spring does not need to be continuously applied. Such adjustment conforms to the common adjustment operation habit of people's quick adjustment. Therefore, the adjustable buffer hinge of the present utility model can achieve the purpose of convenient adjustment. Brief Description of the Drawings

[0009] As Figure 1 , 2 shown, an adjustable buffer hinge includes a hinge cup 1, a hinge base 2, a hinge arm 3 hinged between the hinge cup 1 and the hinge base 2, a cam 5 fixed to the hinge shaft 4 of the hinge arm 3 and the hinge cup 1, and a damper 6 that abuts against the cam 5 to buffer the closing of the hinge cup 1. Of course, the hinge should also include a driving arm hinged between the hinge cup 1 and the hinge base 2 and a torsion spring that drives the driving arm to swing, so as to drive the hinge cup 1 to swing. These belong to conventional designs and will not be elaborated here. In the present utility model, the damper 6 is a non-self-resetting damper and is installed on the outer side of the hinge cup 1. Corresponding to this side, the cam 5 is fixed to the end of the hinge shaft 4 on this side. A slider 7 that slides in the telescopic direction of the damper 6 and a compression spring 8 are also installed on the outer side of the hinge cup 1. A stopper 61 is formed on the cylinder block of the damper 6. The slider 7 abuts against the damper 6 on the side where the damper 6 retracts, and the compression spring 8 abuts against the damper 6 on the side where the damper 6 retracts of the slider 7. A locknut eccentric screw 9 is installed on the top of the hinge cup 1, and the eccentric part of the locknut eccentric screw 9 abuts against the damper 6 on the side where the slider 7 extends.

[0010] When the cabinet door is open, that is, the hinge cup 1 is open, the eccentric screw 9 is rotated with an adjustment tool such as a screwdriver, so that the eccentric part of the eccentric screw 9 moves the slider 7 toward the compression direction of the compression spring 8, and the compression spring 8 is compressed, that is, the telescopic stroke of the compression spring 8 is shortened. In this process, adjusting the anti-loosening eccentric screw 9 only overcomes the elastic force of the compression spring 8, so the adjustment operation can be completed quickly and easily. Then the cabinet door is closed and opened once. During the closing process, the cam 5 that rotates synchronously with the hinge shaft 4 pushes the damper 6, and the damping force of the damper 6 slows down the closing speed of the hinge cup 1 to achieve the buffered closing of the cabinet door. After the cabinet door is opened, the damper 6 is extended and reset under the elastic force of the compression spring 8 until the slider 7 hits the eccentric part of the anti-loosening eccentric screw 9, and the damper 6 is reset. At this time, the length of the damper 6 (that is, the telescopic stroke of the damper) is shorter than before the adjustment, that is, the buffering angle of the damper 6 is smaller than before the adjustment. Similarly, the buffer angle of the hinge can be adjusted by rotating the anti-loosening eccentric screw 9 in the opposite direction. Thus, the buffer angle of the hinge can be adjusted by adopting the utility model. Since the anti-loosening eccentric screw 9 is adopted, its anti-loosening force is relatively large, and the elastic force of the compression spring 8 alone is difficult to drive it to rotate.

[0011] As for the specific installation method of the compression spring 8, the slider 7 and the damper 6, since the compression spring 8, the slider 7 and the damper 6 are all conventional parts, they can be installed using a conventional installation structure, which can be adjusted accordingly in response to various considerations such as processing and assembly. In order to facilitate the installation of the compression spring 8, the slider 7 and the damper 6, the outer side of the hinge cup 1 in this embodiment is fixed with a cavity 10 for installing the compression spring 8, the slider 7 and the damper 6. The cavity 10 is provided with cavities for installing the compression spring 8, the sliding installation slider 7 and the plug-in damper 6. Of course, as a non-automatic reset damper, the head of the piston rod of the damper 6 needs to be clamped and fixed in the cavity 10, which is the conventional installation of the damper.
