The present invention relates to an allowable structure for closing the speed of a door, which minimizes the installation restrictions of the closure.

In general, a closer is installed on a door or the like, and is a device that rotates and closes itself by removing the force applied to the door after rotating the door to open it.

Such closures usually include a damping device that generates a damping force by the working fluid, and a torsion device that generates a restoring force by a spring.

As a technique related to the conventional closure, there has been proposed a "side speed control device and a built-in automatic return hinge device using the same" in Korean Patent Publication No. 10-2008-0112870, which is embedded in a longitudinal groove of the door so as to be able to flow. A single body which is installed, and the upper and lower parts are blocked by upper and lower caps, respectively; A shaft with one end protruding through the upper cap and rotatably supported, and the other end extending into the body; A piston in which an outer circumferential surface is slidably installed along the inner circumferential surface of the body and partitions the inside of the body into upper / lower chambers; Rotation / linear motion conversion means for converting rotational motion of the shaft into axial linear motion of the piston when the rotational force of the door is applied to the shaft according to the opening and closing of the door; A damping means installed on the piston to control the descending and rising speed of the piston in connection with the opening and closing of the door, and to provide a damping function selectively when the piston is raised; When the door is closed, it is composed of return means that provides restoring force to the rotation / linear motion conversion means so as to return the door to the initial position, and the damping means is connected to a guide pin to the inside of the cylindrical portion of the camshaft. A piston rod slidably coupled with a lower end connected to the center of the piston and having a first flow path through which oil can flow between upper and lower chambers; At least one check valve installed in a second flow path capable of flowing the upper / lower chamber provided in the piston to open the second flow path when the door is opened, and to block the second flow path when the door is closed; The front end is inserted into the first flow path of the piston rod to control the flow amount of oil moving from the upper chamber to the lower chamber through the first flow path, and the flow amount of oil moving through the first flow path is variable according to the opening angle of the door. It consists of a hydraulic control rod including a high-speed section setting section and a low-speed section setting section, and side speed adjustment means for adjusting the closing speed of the door by varying the height of the hydraulic control rod through a hole formed in the side of the door.
