Detailed Description
Embodiments of the present utility model are further described below with reference to the accompanying drawings.
As shown in fig. 1, the concealed hinge comprises a base 1, a pin shaft 3 and a rotating arm 5, wherein a groove 11 capable of accommodating the rotating arm 5 is formed in the middle of the base 1, mounting holes 2 used for mounting are formed in two ends of the base 1, a through hole for inserting the pin shaft 3 is formed in the front end of the base 1, the base 1 is hinged to the rotating arm 5 through the pin shaft 3, the rotating arm 5 can rotate around the pin shaft 3, and the rotating arm 5 can be completely accommodated in the groove 11.
As shown in fig. 2-4, the base 1 comprises a base body 10 and a bottom cover 6, two sides of the bottom cover 6 are provided with accommodating grooves 13, a push rod 8 is arranged in each accommodating groove 13, each push rod comprises a rod part and a push head 9, a spring 7 is sleeved on each rod part, one end of each spring abuts against the bottom of each accommodating groove 13, and the other end of each spring abuts against the rear end of each push head 9. The outer sleeve of the pin shaft 3 is provided with the shaft sleeve 4, the two ends of the shaft sleeve 4 are respectively provided with the cam part 15, one end of the rotating arm 5 is hinged between the two cam parts, the cam parts 15 comprise the clamping hooks 16 and the hovering parts, the hovering parts comprise the first circular arc surface 17, the second circular arc surface 18 and the third circular arc surface 19, the curvature of the first circular arc surface 17 is larger than that of the second circular arc surface 18 and larger than that of the third circular arc surface 19, when the rotating arm 5 is positioned in the groove 11, the clamping hooks 16 are matched with the top 9 to limit, no external force acts on the rotating arm 5, the front end of the top 9 is abutted against the hovering parts when the rotating arm 5 rotates clockwise, the change of the curvature of the circular arc surface of the hovering parts enables the ejector rod to displace, so that the deformation of the spring is changed, and the force applied to the cam part 15 by the top 9 is balanced with the friction force of the rotation of the cam parts 15, and hovering is realized. Further, the front end of the plug 9 is arc-shaped, so that the friction force of the plug 9 and the cam part 15 relative to each other is reduced, and the hinge is rotated more smoothly.
In this embodiment, the two sides of the bottom cover 6 are provided with the first buckle 12, the base 10 is provided with the second buckle which is matched with the first buckle in a buckling manner, and the bottom cover 6 and the base 10 are detachably buckled, so that the maintenance and the installation are convenient.
In this embodiment, the shaft sleeve 4 is provided with a limiting groove 14, the limiting groove 14 is in a wave shape, the rotating arm 5 is provided with a limiting protrusion 20 corresponding to the limiting groove 14, and the limiting protrusion 20 is matched with the limiting groove 14 to ensure that the rotating arm 5 cannot loose in the rotating process, so that the transmission is stable.
The examples should not be construed as limiting the utility model, and any non-inventive modifications based on the spirit of the utility model should be regarded as being within the scope of the utility model.
