Description
Technical Field
The utility model relates to a hinge technical field, concretely relates to four-bar hinge and buffer thereof.
Background
The four-bar hinge for opening and closing the cabinet door mainly comprises a hinged support for fixing the cabinet body, a hinged cup for fixing the cabinet door and a four-bar mechanism for connecting the hinged support and the hinged cup. The four-bar linkage is usually provided with a torsion spring for driving the four-bar linkage to swing for closing the door. In order to achieve the buffer self-closing of the cabinet door, a damper for buffering the door closing swing of the four-bar mechanism is usually additionally arranged. The damper is mounted with a selective hinge cup and a selective hinge base. For the hinge seat installation, a rocker hinged with the four-bar mechanism is installed on the hinge seat, the other end of the rocker is hinged with the damper, and the other end of the damper is hinged with the hinge seat. The four-bar mechanism drives the rocking bar to swing when closing the door and swinging, the rocking bar compresses the damper, and the damping compression reaction of the damper acts on the rocking bar to buffer the swinging of the rocking bar, so that the self-closing swinging of the hinge is buffered. However, the damper of the hinge adopts a hinge mode, a pin shaft is required to be used for hinge, the pin shaft is required to be punched and riveted for fixation during installation, and the problems of complex installation procedures, low installation efficiency and the like exist.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a four connecting rod hinges easy to assemble and buffer thereof.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a buffer of four-bar hinge, includes and drives its wobbling rocker and buffering rocker wobbling attenuator, its characterized in that by four-bar linkage with the free bearing pin joint: the cylinder body of the damper is slidably mounted in the hinged support, the bottom end of the cylinder body abuts against the swinging end of the rocker, and the piston rod end of the damper abuts against a fixed part of the hinged support.
On the basis, a mounting seat is fixed in the hinged support, the cylinder body is slidably mounted in the mounting seat, and the end of the piston rod is abutted to the mounting seat.
On the basis, wing-shaped sliding parts which are connected with the mounting seat in a sliding mode are formed on two sides of the cylinder body respectively.
On the basis, the swing end of the rocker is provided with a roller which is abutted against the cylinder body.
Another technical solution adopted to solve the above technical problems is: the utility model provides a four-bar hinge, is including hinge cup, free bearing and articulate the four-bar linkage between hinge cup and free bearing, and four-bar linkage installs its swing spring of closing the door of drive, its characterized in that: the four-bar hinge has the damping device as described above.
Adopt the utility model discloses the beneficial effect who brings: because the utility model discloses establish into the installation of attenuator and slide in the free bearing, cancelled current articulated formula installation, the installation is simple swift, can effectively promote the installation effectiveness.

Detailed Description
As shown in fig. 1-3, a four-bar hinge, including hinge cup 1, free bearing 2 and articulate the four-bar linkage 3 between hinge cup 1 and free bearing 2, four-bar linkage 3 installs and drives its swing spring 4 that closes the door the utility model discloses in, four-bar hinge has the swing buffer that closes the door of buffering four-bar linkage 3.
The buffer device of the four-bar hinge comprises a rocker 5 which is pivoted with the hinged support 2 and driven by the four-bar mechanism 3 to swing and a damper 6 which buffers the swing of the rocker 5. The utility model discloses in, cylinder body 6.1 slidable mounting of attenuator 6 is in free bearing 2, and the bottom of cylinder body 6.1 offsets with the swing end of rocker 5, and the piston rod 6.2 end of attenuator 6 offsets with a fixed part of free bearing 2.
Normally, the rocker 5 is hinged to a swing end of the four-bar linkage 3 through a link 7, and swings following the swing of the four-bar linkage 3. The utility model provides a four link mechanism 3 drives the swing of rocker 5 when closing the door swing, and the swing end of rocker 5 is towards the swing of 6 directions of attenuator, and 6.1 compression dampers 6 of cylinder body of ejection attenuator 6, the damping force reaction of attenuator 6 are in four link mechanism 3, the swing of closing the door of buffering four link mechanism 3. When the door is opened, the reset spring in the damper 6 drives the damper to extend out and reset.
In this embodiment, a mounting seat 8 is fixed in the hinged support 2, the cylinder 6.1 of the damper 6 is slidably mounted in the mounting seat 8, and the end of the piston rod 6.2 abuts against the mounting seat 8. Specifically, wing-shaped sliding portions 6.3 slidably connected to the mounting seat 8 are formed on both sides of the cylinder 6.1. Correspondingly, two sliding grooves 8.1 for accommodating the sliding part 6.3 to slide are formed in the mounting seat 8. And the swinging end of the rocker 5 is provided with a roller 9 which is propped against the cylinder body 6.1.
