Detailed Description

The utility model is further described below with reference to embodiments shown in the drawings in which:

as shown in figures 1-3, the concealed hinge comprises a rotating seat 1 fixedly arranged on a door frame and a connecting seat 2 rotatably arranged on the rotating seat 1, wherein a hinge 3 for being inserted in a door body is fixedly arranged on the connecting seat 2, the hinge 3 and the door body are detachably and fixedly connected through a fastener, the plane where the hinge 3 is positioned is parallel to the plane where the door body is positioned, a plurality of raised strips 4 for being buckled in the door body and extending along the axial direction of the rotating center of the connecting seat 2 are fixedly arranged on the lower end face of the hinge 3, a clamping groove matched with the raised strips 4 in language is formed in the door body, the raised strips 4 are clamped in the clamping groove, a plurality of mounting holes 5 for concealed mounting the hinge 3 on the door body are formed in the hinge 3, the mounting holes 5 are counter bores, the fastener is a countersunk screw, the hinge 3 is fixedly arranged in the door body after passing through the mounting holes 5 through the raised strips 4 and the clamping groove, the stress requirement of the countersunk screw is reduced, thus the thickness requirement on materials can be reduced, the door body is more reasonably buckled with the door body, the door body can not be mounted on the surface of the door body through the door body, and the door body can not be assembled in the front of the door body through the side of the door body, and the door body can be prevented from being assembled under the condition of the situation of being more attractive. When the hinge 3 is positioned through the raised strips 4, the situation that the door body is inclined and deformed after being installed can be effectively avoided. When the anti-theft door is installed, the hinge 3 is inserted into the door body and fixed through the fixed setting of the rotating seat 1 on the door frame, the hinge 3 is positioned in the door body, the outside cannot be dismantled, the anti-theft effect is good, the hinge 3 is installed in the door body, and all sealing strips and heat insulation broken bridges are avoided.

The connecting seat 2 is fixedly provided with a connecting plate 6 on one side facing the door body, and the hinge 3 is fixedly arranged at one end of the connecting plate 6 far away from the connecting seat 2. The connecting plate 6 gradually inclines downwards from the connecting seat 2 to the hinge 3. Through the connecting plate 6 that the slope set up, the hinge 3 that makes connecting plate 6 keep away from connecting seat 2 one end is close to the plane that the door frame was located for connecting seat 2 more, makes hinge 3 in inserting the internal back of door, and the door body can be comparatively laminating be located the door frame, comparatively level and smooth between the door frame after the door body is closed, more pleasing to the eye.

The fixed mounting panel 7 that is used for fixed this rotation seat 1 that is provided with in rotation seat 1 below, this mounting panel 7 is fixed to be set up in the door frame, and above-mentioned rotation seat 1 pass through rotation seat 1 and door frame back and this mounting panel 7 fixed connection through countersunk screw, the mounting panel 7 is fixed to be provided with a downwardly extending and fixed backup pad 9 that sets up on the door frame inner wall towards one side of above-mentioned hinge 3, and rotation seat 1 and mounting panel 7 clamp the door frame after the installation and make the installation that above-mentioned rotation seat 1 can be firm on the door frame through integrated into one piece's mounting panel 7 and backup pad 9, and the installation is comparatively firm.
