Description

Hydraulic Auto Shock Hinges

The present invention relates to a hydraulic autobuffer hinge. In more detail, the right turn spiral protrusion cam is formed on both sides of the rotating shaft installed in the hinge body, and the right turn spiral guide groove is installed in the reciprocating operation tube, and the left turn spiral guide groove is formed on the outer circumference of the reciprocating operation tube to fix the fixed tube. The guide protrusions formed to be inclined left turn on both sides of the lower part are inserted so that the reciprocating actuating tube descends or rises as the rotary shaft rotates, or is formed at the lower end of the reciprocating actuating tube according to the rotation of the rotating shaft, or the pistons installed separately are installed in the cylinder. In reciprocating operation, oil is moved to the top of the piston or to the bottom of the piston. At this time, the buffer is generated by the hydraulic pressure acting during the movement so that the door is closed slowly. Here, the load by the hydraulic pressure acting on the rotating shaft is uniformly applied to the rotating shaft so that the spiral guide groove, the spiral cam or the protruding piece are not damaged in the course of rotating the rotating shaft left and right.

And when a fire occurs and rises above a certain temperature, the door closes automatically to reduce the spread of flame to the maximum, thereby minimizing property damage and human injury.

Conventional hinges are connected to door frames and doors so that the door can be opened or closed. First, the door closes automatically, while the shock absorber to close slowly is the same as the door closer configured separately from the hinge. It is common to install the buffer at the top of the radish, but this is complicated in structure and has a high rate of failure and needs to be installed at the upper part of the door frame and door. There was a bad question.

In order to solve such a problem, the patent number 156093 "Hydraulic-actuated automatic hinge hinge", which is owned in Korea, installs a piston with an on-off valve and a check valve at the end and rotates the counterclockwise spiral cam and the counterclockwise spiral cam. A reciprocating tube formed with a long hole is installed in the cylinder, and a right rotating spiral cam protrusion formed protruding from the rotating shaft is installed in a right rotating spiral cam long hole, and another left rotating spiral cam long hole is inserted with a bolt threaded by a cylinder. It is to balance when moving down, but this is smoothly buffered by the hydraulic pressure when opening and closing the door, but the right turn spiral cam projection formed on one side of the rotating shaft is tasted by the right turn spiral cam slot formed in the reciprocating pipe. When the buffering action is made by hydraulic pressure during the automatic process, a large load is applied to one side of the rotating shaft by the spiral cam protrusion formed on one side of the rotating shaft, so that the rotating shaft is cut or the threaded bolt is cut or broken. There is this.

The present invention is to solve the problems described above and to form a right turn spiral projection cam on both sides of the rotating shaft to be installed in the hinge body in order to facilitate the buffering action by the hydraulic pressure to be fitted in the right turn spiral guide groove formed in the reciprocating operation pipe, The left-handed spiral guide groove is formed on the outer circumferential sides of the reciprocating actuating tube so that the guide protrusion pieces inclined to the left formed on both sides of the lower part of the fixed tube are inserted so that the reciprocating actuating tube descends or rises according to the rotation of the rotating shaft. The piston, which is formed as a single unit or separately installed at the lower end of the tube, moves the oil to the upper portion of the piston or moves to the lower portion of the piston while reciprocating up and down in the cylinder. At this time, the buffer is generated by the hydraulic pressure acting during the movement so that the door is closed slowly. Here, the load by the hydraulic pressure acting on the rotating shaft is uniformly applied to the rotating shaft, so that the spiral guide groove, the spiral cam or the guide protrusion are not damaged while the rotating shaft rotates left and right, and a fire occurs at a temperature higher than a predetermined temperature. When the temperature rises, the door closes automatically to minimize the spread of flame.
