The present invention relates to a door opening and closing device, and more particularly to a door opening and closing device that is fixed to the door frame and the door while a pair of hydraulic hinge and the spring hinge.

In general, a building is provided with a door for the purpose of entry and exit, such door is provided with a switchgear is opened and opened by a plurality of hinges between one side end and the door frame so as to swing from the door frame according to the entrance.

As described above, there are various types of opening and closing devices used in the door and the door frame, but recently, a door opening and closing device in which a hydraulic hinge and a spring hinge are paired for safety and convenience of the occupant is introduced. Since the top and bottom between the door and the door frame is mounted, the open door is automatically closed, and it is being used to close slowly.

Among these door opening and closing device is proposed in Korean Utility Model No. 0281610, the hydraulic hinge is installed to the top of the door and the door frame as shown in Figure 5 to 6 of the rotating member 110 so that the door does not close suddenly An oil passage 114a is formed in the piston guide hole 112 in the cylindrical housing 111, and the piston 115 is screwed to the pivot shaft to move up and down to form a supply passage 115a. And the door fixing bracket 116 is formed at an outer end thereof and fixed to one side of the door, and the oil inside the cylinder is rotated into the cylindrical housing 121 of the fixing member 120 corresponding to the housing. A cylinder 122 having the outflow hole 122a formed therein and an upper portion thereof have an adjustment bolt 124 mounted on the head 125 to adjust an outflow amount of oil from the outflow hole to form an oil circulation path 126. And in the hydraulic hinge (1) formed with a door frame fixing bracket 128 is fixed to one side of the door frame to the outer end, a constant so that the outflow hole (122a) and the oil circulation path 126 communicates with the upper surface of the cylinder (122) It is shown to have an oil outlet 100 to form a plurality of support protrusions 102 at intervals.

Accordingly, when the oil in the cylinder is discharged through the outflow hole due to the piston which is raised by the rotation of the rotation shaft according to the opening and closing of the door, the oil is discharged through the wide oil passage between the support protrusions, and thus foreign matters contained in the oil, etc. It is to have a condition that can be prevented from being blocked by.

In addition, the outer surface of the piston 115 and the inner surface of the piston guide 112 are formed in a polygon corresponding to each other to combine, so that when the piston on the pivot shaft according to the opening and closing of the door is raised and lowered on the piston guide It will have a greater bearing capacity even under pressure to prevent the twist or damage generated in the guide piece of the conventional piston and the guide groove of the piston guide.

In addition, the bottom of the outlet hole 122a and the adjustment bolt 124 is formed so that the upper side is wide and the lower side is narrowly formed so as to correspond to each other, it is possible to adjust the gap between the control bolt and the outlet hole in more detail to adjust the outflow of oil It will also provide the convenience of adjusting the operation of the hydraulic hinge can be closed to the user desired speed.

In addition, the spring hinge is paired with the above-mentioned hydraulic hinge as shown in Figure 7 to 8 is installed as the lower end of the door and the door frame spring hinge to close the open door by the compression tension of the built-in spring (S) In (2), the spring-type hinge 2 is fastened to the lifting hole 200 is lowered as the upper end of the built-in spring is fixed and the lower end is configured to have a greater compression tension.
