Hereinafter, the process of easily adjusting the speed and adjusting the back check of the door in the process of opening or closing the door using the control valve 19 of the compact floor hinge according to an embodiment of the present invention This will be described with reference to FIGS. 3A to 3C and 4A to 4C. 3A to 3C are operation cross-sectional views illustrating the operation of the compact floor hinge according to an embodiment of the present invention, and FIGS. 4A to 4C illustrate the back check operation of the compact floor hinge according to an embodiment of the present invention. Operation cross-sectional views are shown below.

First, the compact floor hinge according to an embodiment of the present invention will be described with reference to FIGS. 3A to 3C to easily adjust the rotational angular velocity of the door in the process of closing the door by using the adjustment valve unit 19. do.

3A is a cross-sectional view of the body portion when the door with the compact floor hinge mounted according to one embodiment of the present invention closes at an opening angle of 20 ° at the maximum opening angle, and is defined by "b" and "by the left piston 21. The inner passage of d " is opened and hydraulic oil flows from " b " to the inner passage of " d " in accordance with opening and closing of the second regulating valve 19-2.

Then, as the door is rotated at a stop angle of 0 ° at an opening angle of 20 ° and closed at a stop angle of 0 ° in FIG. 3C as shown in FIG. 3B, the left piston 21 is moved to the left by the cam 2 to the left. It is pushed further to block the inner passage of "b". At this time, the hydraulic oil flows from the inner passage of "a" to the inner passage of "c" in accordance with the opening and closing of the first adjustment valve 19-1.

According to the opening and closing of the first control valve 19-1 and the second control valve 19-2, the moving path of the hydraulic oil contained in the body housing 1 is adjusted, and the rotational angular velocity of the door is closed in the process of closing the door. I can adjust it.

On the contrary, when the door mounted with the compact floor hinge is opened by an external force, the right piston 15 is pushed to the right by the cam 2 as shown in the cross section of the body shown in FIG. from the inner passage of f " to the inner passage of " e ".

Then, as the right piston 15 is pushed further to the right by the cam 2, the right piston 15 blocks the inner passage of "f", whereby the hydraulic oil therein is the inner passage of "g". Flows into the inner passage of "e".

Thus, although the user initially uses some force in opening the door, the

rollers

16 and 20 that abut against the cam 2 are ideally positioned with the cam 2 vanes since the door opening angle exceeds 15 degrees. The cloud allows the user to open the door up to about 75 degrees with very little force.

At this time, according to the opening and closing degree of the third adjustment valve (19-3), the moving path of the hydraulic oil flowing from the inner passage of "g" to the inner passage of "e" is blocked or the flow rate is delayed, so that The back check can be adjusted to attenuate and prevent sudden jumps to full open, preventing the door from hitting the wall and breaking.
