Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hinges, in particular to a double-buffered hidden hinge. Background Art
[0002] In high-end furniture, doors and windows and other decorations, in order to make the two connected objects look like there is no obvious connection mark, hidden hinges are usually used to match the installation of furniture, doors and windows. Traditional hidden hinges usually consist of two parts: a "fixed part" installed on one object and a "movable part" installed on another object. When the hinge is fully closed, these two parts can be completely hidden inside the object, and the existence of the hinge cannot be seen. When the two connected objects need to be opened or closed, the movable part will slide out of the fixed part, so that the two objects can rotate relative to each other. When closing, the hidden hinge will automatically retract so that the hinge is no longer exposed. The opening and automatic retraction of the hinge are buffered by the buffer inside the fixed part and the hinge automatically closes the product connected;
[0003] When assembling a conventional hinge, only one buffer is provided inside to buffer and reset the components connected to the movable part. When the object carried by the movable part is heavy, the buffer built into the fixed part has difficulty in resetting and buffering, and there is a problem that the movable part and the fixed part cannot be reset, which brings instability to the use of the hinge.
[0004] Therefore, the utility model provides a double-buffer hidden hinge with two buffer structures built in the fixed part. Summary of the invention
[0005] The purpose of the utility model is to provide a double-buffered hidden hinge to solve the problems raised in the above background technology.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The bottom frame is provided with a first avoidance groove and a second avoidance groove, and a buffer spring and a buffer are respectively arranged in the first avoidance groove and the second avoidance groove, the joint nail at the top of the buffer spring and the top of the buffer are respectively rotatably connected to the two ends of the main swing arm, the outer edge of the rocker at the bottom of the buffer spring is provided with a groove, the bottom frame is provided with an upper frame for limiting the buffer spring and the main swing arm on the bottom frame, the upper frame is provided with a third avoidance groove and a fourth avoidance groove corresponding to the first avoidance groove and the second avoidance groove, and the third avoidance groove is provided with a convex point that cooperates with the groove to limit the buffer spring;
[0009] The adjusting blocks at the front ends of the main swing arm and the auxiliary swing arm are located above the fixed part, and the movable part is fixedly connected to the auxiliary swing arm.
[0010] Furthermore, a slider is connected to one side of the bottom frame, and an eccentric nail connected to the slider is provided on the back cover for adjusting the slider forward and backward. When the eccentric nail rotates, the slider is pushed forward and backward inside the fixed part as the eccentric nail rotates, thereby realizing the adjustment of the front and rear distance between the movable part and the fixed part.
[0011] Furthermore, guide strips are respectively provided on the front and back sides of the slider, and guide grooves are respectively provided on the rear cover and the front cover for cooperating with the guide strips for guiding the movement forward and backward. When the bottom frame moves forward and backward inside the fixed part, the guide strips move in the guide grooves, thereby achieving the purpose of the bottom frame stabilizing the forward and backward movement of the movable part and the fixed part.
[0012] Furthermore, the side of the buffer corresponding to the upper frame is provided with an anti-skid pad, and the anti-skid pad limits the position of the buffer between the upper frame and the bottom frame to prevent skidding.
[0013] Furthermore, the adjusting block is provided with an adjusting screw connected to the bottom frame, and the distance between the adjusting block and the bottom frame is adjusted up and down by the adjusting screw, so as to achieve the purpose of adjusting the distance between the movable part and the fixed part.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] The double-buffer hidden hinge has a buffer spring arranged in the fixed part to cooperate with the buffer to connect the auxiliary swing arm and the main swing arm connected to the movable part. When the main swing arm and the auxiliary swing arm are opened with the movable part and the fixed part, the main swing arm and the auxiliary swing arm apply pressure to the buffer position with the opening of the movable part and the fixed part, and the buffer spring is stretched with the inclination of the auxiliary swing arm, so that the buffer buffers the opening of the movable part.
[0016] On the contrary, when the movable part and the fixed part are closed, the movable part rotates toward the fixed part, the auxiliary swing arm compresses the supporting spring, and the buffer extends and resets accordingly, thereby automatically closing the movable part and the fixed part in coordination with each other. The buffer spring and the buffer coordinate the opening and closing of the movable part and the fixed part, thereby improving the opening and closing stability of the fixed part and the buffer part, and at the same time improving the bearing capacity of the coordinated connection of the movable part, the bearing capacity can reach 25kg, thereby improving the firmness of the hinged door and window furniture when used together.
