Abstract

The invention relates to a hardware door accessory, and discloses a hidden-type self-closing hinge structure with a buffer function. The hidden-type self-closing structure comprises a fixed machine seat, a movable machine body and a linkage assembly. The fixed machine seat and the movable machine body are buried on a corresponding door frame and a corresponding door plate. A cam elastic abutting mechanism comprises transverse sliding blocks, longitudinal sliding blocks, cams, a spring, dampers, cam connecting shafts and damper connecting shafts. The transverse sliding blocks are mounted in transverse sliding grooves of a movable machine seat. The longitudinal sliding blocks are mounted in vertical sliding grooves of the movable machine seat. The cams are hinged into the movable machine seat through the cam connecting shafts. The spring is arranged between the upper longitudinal sliding block and the lower longitudinal sliding block in an abutting mode. The two ends of the dampers are hinged into damping groves of the upper longitudinal sliding block and the lower longitudinal sliding block through the damper connecting shafts correspondingly. Under the action of the hidden-type self-closing structure, the function that after being opened by a certain angle, a room door can be positioned in a suspended mode and automatically and slowly closed can be achieved, and due to the factthat the hinge is mounted in a hidden mode, the overall appearance effect of room door mounting is improved greatly.

Description

Technical field: [0001] The invention belongs to the category of door hinges, and in particular relates to a door hinge capable of automatically closing the door slowly and hovering for positioning within a specific angle range after the door is opened. Background technique: [0002] With the progress and development of social science, the technical level of products in our country is also constantly improving, but there are still some deficiencies in traditional door hinges. Door hinges are mostly surface-mounted hinges, which have the following disadvantages: 1. They are not beautiful and can easily damage the overall effect of the door; Potential safety hazard; 3. Due to design problems, the door is often not closed properly. And the traditional concealed door hinge, although it is concealed installation, it can't realize the effect of automatic door closing and positioning. Invention content: [0003] In order to solve the above-mentioned problems in the existing pro...
