Buffering side hidden hinge

Abstract

The utility model discloses a buffering side hidden type hinge which comprises a hinge cup, a hinge seat, a hinge arm hinged between the hinge cup and the hinge seat and a damper buffering closing of the hinge cup, the damper is installed on the outer side portion of the hinge cup, and a cam abutting against a damper cylinder body is fixed on the side corresponding to the hinge arm and the end portion of a hinge shaft of the hinge cup. And the hinging shaft and the hinging arm are fixed in the circumferential direction. Due to the fact that the damper is installed on the outer side portion of the hinge cup, the damper can be shielded by the installation wing plate of the hinge cup. The damping buffer is mounted on the side, so that the damper can be well hidden, the surface appearance of the hinge is simple and neat, and the market acceptability of the hinge cup buffering hinge is greatly improved.

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 a damping buffer (also known as a damper). One type is that the damper is installed on a hinge base fixed to a cabinet wall, and the other type is installed on a hinge cup fixed to a cabinet door. For the one installed on the hinge cup, the damper is installed inside the cup body of the hinge cup. In sales and daily use, people can clearly see the damper inside the hinge cup, resulting in an unsatisfactory surface appearance of the hinge cup, which is usually unappealing. Therefore, it is necessary to develop a hinge with a hidden installation of the damper. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a hinge with a hidden installation of a damping buffer.

[0004] The technical solution adopted to solve the above technical problem: A buffer side-mounted hidden hinge, comprising a hinge cup, a hinge base, a hinge arm hinged between the hinge cup and the hinge base, and a damper for buffering the closing of the hinge cup. It is characterized in that: The damper is installed on the outer side of the hinge cup. Corresponding to this side, a cam for abutting against the cylinder body of the damper is fixed at the end of the hinge axis of the hinge arm and the hinge cup, and the hinge axis and the hinge arm are circumferentially fixed.

[0005] On the above basis, a cavity body for installing the damper is fixed on the outer side of the hinge cup.

[0006] On the above basis, the damper includes a non-self-resetting damper and a return spring.

[0007] The beneficial effects brought by the utility model: Since the damper of the hinge of the utility model is installed on the outer side of the hinge cup, the damper will be blocked by the installation wing plate of the hinge cup. This side-mounted installation method of the damping buffer can well hide the damper, making the surface appearance of the hinge simple and tidy, and greatly improving the market acceptance of the hinge cup buffer hinge. Description of the Drawings

[0008] Figure 1 It is a side structure schematic diagram of the buffer side-mounted hidden hinge of the utility model;

[0009] Figure 2 It is a side structure schematic diagram of the buffer side-mounted hidden hinge of the utility model after removing the cavity body. Detailed Embodiment

[0010] Such as Figure 1 、 2As shown in the figure, a buffer side-mounted hidden 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, and a damper 4 for buffering 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 for driving the driving arm to swing, so as to drive the hinge cup 1 to swing. In the present invention, the damper 4 is installed on the outer side of the hinge cup 1. Corresponding to this side, a cam 6 that abuts against the cylinder body of the damper 4 is fixed at the end of the hinge axis 5 of the hinge arm 3 and the hinge cup 1, and the hinge axis 5 and the hinge arm 3 are circumferentially fixed.

[0011] Generally, most of the dampers 4 adopt self-resetting dampers. When the hinge cup 1 is in the fully open state, that is, the state shown in the attached drawing, the damper is in the extended state. When the hinge cup 1 is driven to swing for closing the door, the cam 6 that rotates along with the hinge axis 5 pushes against the damper 4, and the damping force of the damper 4 buffers the swing of the hinge cup 1, so that the hinge cup 1 closes slowly. Since the damper 4 is installed on the outer side of the hinge cup 1, the damper 4 will be blocked by the mounting wing plate 11 of the hinge cup 1, making the surface appearance of the hinge more concise.

[0012] For the convenience of installing the damper 4, a cavity body 7 for installing the damper 4 is fixed on the outer side of the hinge cup 1.

[0013] In addition to selecting the conventional self-resetting damper, the damper can also select a non-self-resetting damper and a return spring. For example, the damper 4 in this embodiment includes a non-self-resetting damper 41 and a return spring 42. The return spring 42 is used to push against the top block on the outer wall of the cylinder body of the non-self-resetting damper 41. Of course, for the non-self-resetting damper 41, the head of its piston rod needs to be clamped and fixed, which is the conventional installation of the damper.

Claims

1. A buffer side-mounted hidden hinge, comprising a hinge cup, a hinge base, a hinge arm hinged between the hinge cup and the hinge base, and a damper for buffering the closing of the hinge cup, characterized in that: The damper is installed on the outer side of the hinge cup. Corresponding to this side, a cam that abuts against the cylinder body of the damper is fixed to the end of the hinge axis of the hinge arm and the hinge cup, and the hinge axis is circumferentially fixed to the hinge arm.

2. The buffer side-mounted hidden hinge according to claim 1, characterized in that: A cavity body for installing the damper is fixed to the outer side of the hinge cup.

3. The buffer side-mounted hidden hinge according to claim 2, wherein: The damper includes a non-self-resetting damper and a return spring.
