Problems solved by technology

The buffer hinge of the above structure, because the damper piston rod is exposed, is not only unsightly, but also achieves buffering by bumping the damper piston rod when the movable seat swings when closing the door. Force, and this radial force will have an adverse effect on the piston rod and the cushioning effect. Therefore, in order to reduce the radial force of the movable seat on the piston rod, it is necessary to have certain requirements for the transmission part between the piston rod and the movable seat. , it is also necessary to ensure the stiffness of the piston rod, resulting in a more complicated structure of the hinge

Embodiment 1

[0035] The structure of the large-opening door buffer hinge of the present invention is as follows: figure 1 , 2 , 3, 4, 7, and 8, including a fixed seat 17, a connecting arm 1, a connecting rod assembly, a movable seat 14 and a self-resetting damper 6, wherein the connecting arm 1 is connected to the fixed seat 17, and the connecting rod assembly includes the first A connecting rod 5, the second connecting rod 7, the third connecting rod 8, the fourth connecting rod 13, the spring seat 9, the connector 12, the spring 10, wherein one end of the first connecting rod 5 and the third connecting rod 8 are respectively connected with The middle part and the front end of connecting arm 1 are hinged, and the other end of the first connecting rod 5 and the third connecting rod 8 are respectively hinged with one end of the second connecting rod 7 and the fourth connecting rod 13, and the second connecting rod 7 and the fourth connecting rod The other end of 13 is hinged with movable s...

Embodiment 2

[0039] The structure of the large-opening door buffer hinge of this embodiment is similar to that of Embodiment 1. The difference is that one end of the spring 10 corresponding to the connector 12 is provided with a contact 11, and the contact 11 is located between the connector 12 and the spring 10, and the door is closed. At this time, the connecting piece 12 compresses the spring 10 by pushing the contact 11. In this implementation, in order to reduce noise generated by the friction between the connecting piece 12 and the contact 11, the contact 11 is preferably made of rubber material. In addition, in order to stably install the damper 6 on the damper seat 18 and facilitate the positioning of the damper 6, the damper seat 18 is provided with a fixing groove 181 at the outer end position of the piston rod 61 corresponding to the damper 6, and the piston of the damper 6 The outer end of the rod 61 is inserted into the fixing slot 181 .

Abstract

The invention discloses a large-opening-degree door buffering hinge which comprises a fixed seat, a connecting arm, a connecting rod assembly, a movable seat and a self-resetting type damper. The connecting arm is connected with the fixed seat, the connecting rod assembly comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, one end of the first connecting rod and one end of the third connecting rod are hinged to the middle and the front end of the connecting arm respectively, the other end of the first connecting rod and the other end of the third connecting rod are hinged to one end of the second connecting rod and one end of the fourth connecting rod respectively, the other end of the second connecting rod and the other end of the fourth connecting rod are respectively hinged to the movable seat, the middle of the second connecting rod is hinged to the middle of the third connecting rod, the damper is arranged on the connecting arm, and the third connecting rod can drive the damper. When the movable seat swings to a set angle in the door closing direction, the third connecting rod starts to drive the damper, the speed of the movable seat approaching a furniture body is reduced due to the damping function of the damper, the buffering function is achieved, and a door body is prevented from seriously colliding with the furniture body.

Description

technical field [0001] The invention relates to a hinge, in particular to a large-opening door buffer hinge for furniture doors. Background technique [0002] At present, the furniture industry generally uses hinges to connect cabinet doors when manufacturing furniture. This kind of door hinge is equipped with a spring device, which makes the door have a compressive force when opening and closing the door, eliminating the need for magnetic attraction or bolt fixing in the past. Easy to use without hassle. Its shortcoming is that due to the resilience of the spring, the door and the cabinet body will collide when the door is closed, making noise, and even breaking the badly placed or fragile items in the cabinet. Hinge. There are two kinds of dampers for existing furniture hinges with a buffer function: one is a self-resetting damper, and its piston rod always has a force to stretch out. Assuming that the cylinder of the damper is fixed, when the piston rod is pushed inwar...
