The invention relates to a hinge device for pulling back a door. The device comprises a pull-back slide block, a hinge pin, a door hinge plate, a pull-back rod device, a box hinge plate device, a pull-back tension spring and a door stop pin. The door hinge plate fixed to the door under the external force effect rotates around the hinge pin, the pull-back slide block connected to the door hinge plate drives the pull-back rod device to slide in the box hinge plate device, so that pull-back tension spring is pulled, and changeable torque to the door is generated by the pull-back tension spring according to the change of the curved face of a curved face hole in the pull-back slide block and the stretching length of the pull-back tension spring; when the door is about to be closed, large torqueto the door is generated by the pull-back tension spring which generates force larger than that of the door, door closing is powerful, in the door opening process, torque to the door is basically balanced by the pull-back tension spring which generates force equal to that of the door, and the pull-back tension spring can stay at any position under the effect of friction force; when the door rotates to the highest opening degree, the door stop pin on the door hinge plate coincides with a door blocking groove in the box hinge plate device, accurate positioning is achieved when the door is completely opened, and the whole process is full and noiseless.
Description
technical field [0001] The present invention relates to door pull back hinge devices. Background technique [0002] At present, most door hinge devices and pull-back devices are separate, which is inconvenient to assemble and disassemble, takes up space, is not round when opening and closing the door, and requires additional door stoppers. For this reason we have designed the door pull-back hinge device to solve the deficiencies of existing devices. Contents of the invention [0003] The door pull-back hinge device provided by the present invention is integrated with the hinge, pull-back and doorstop device, which is convenient to assemble and disassemble. Round and silent, the door can stay in any position. The present invention is achieved through the following technical solutions. [0004] The door pull-back hinge device includes: [0005] The door hinge plate is a U-shaped plate fixed on the door, which is hinged with the box hinge plate device through the hinge pi...
