Since the door hinge must be kept closed at all times, a door automatic return system of various structures is installed in the door hinge of the door, and most of these structures include sliding and reverse rotation of the hinge shaft and cam during frequent opening and closing operations of the door. O-rings fitted between the cover mounted on the opening and the outer circumferential wall of the hinge shaft are unevenly worn due to the change of the center of the hinge shaft, which is the rotating shaft, in the process of repeating the vertical movement of the upper and lower plates. As the oil in the cylinder leaks, the adjustment of the door opening and closing speed is smooth. This will be achieved not support war problems occur.

Due to the problems of the switchgear, when the door is opened or closed, the function of adjusting the speed of opening and closing is lost, and the door is closed rapidly. Therefore, the door and the door are frequently collided with each other. Problems will arise.

As a problem of such a door opening and closing device of the conventional door, the oil cylinder has a problem, namely, due to the degradation of the sealing effect and the hardening of the oil due to the wear and damage of the cylinder or hydraulic piston and O-ring.

It demonstrates the effect of the present invention made of the above-described configuration.

1 is a state in which the door (d) is closed and FIG. 3 is a view showing that the degree is open by rotating the angle to 90 ° when the door (d) is pushed by the door (d) to the hinge axis (h) as a starting point When the rotation of the door (d) is started and the primary gear (10) fixed to the hinge shaft (h) is rotated, the gear (11) of the primary gear (10) is engaged with one rack gear (20) rack gear 20 and the rod 23 is moved horizontally at this time the door return shot spring 22 is retracted.

In addition, when the door d is rotated, the first power transmission gear 30 arranged under the motive gear 10 also rotates at the same time, and the second power transmission gear meshed with the first power transmission device 30 ( In the state in which the door d is closed as shown in FIG. 1, the rotating body 110 fixed to the coaxial shaft 112 and built in the circular space 103 of the cylindrical housing 100 is rotated as shown in FIG. 3. In the state where the steel ball 114 is in contact with the inner surface of the thick one side wall 101 of the cylindrical housing 100, the center of the upper and lower shafts 111 'and 111 of the rotating body 110 and the one side wall 101 Since the gap is closest to the state, the door opening and closing force adjustment spring 116 is most contracted by the steel ball 114.

In this state, when the rotating body 110 rotates due to the rotation of the door d, the steel housing 114 moving along the rotating body 110 gradually moves away from the center of the rotating body 110. As the spring 116 contracted by being moved along the inner wall of the) gradually opens, the elastic force of the door opening / closing force adjusting spring 116 is weakened, so that the door d is easily opened while being lightly and gently rotated.

When the door d is released in the state of FIG. 3 and the hand is released from the door d, the retracted door return spring 22 is pushed and pushes the operation rod 23 and the operation rod 23. As the connected rack gear 20 returns, the driving gear 10 is rotated so that the door d is closed as shown in FIG.

When the door (d) is closed as described above, since the rotating body 110 returns to the state of FIG. 1, the steel ball 114 fitted to the rotating body 110 moves toward the thick one side wall 101 of the housing 100. Therefore, the resilience generated by the contraction of the door opening and closing force adjustment spring 116 becomes stronger, and as the pressure applied to the steel ball 114 becomes stronger, the closing speed of the door d is lowered. The elastic force of the force adjustment spring 116 is to adjust the elastic force by tightening or loosening the spring elastic force adjusting member 115.

The opening and closing operation of the door of the present invention is to perform the same operation when the door (d) is pushed into the building or the door (d) while pushing out from the building.

In addition, the configuration of Figure 4 is different from the configuration of the cylindrical housing (100a) of the device of the door opening and closing force control means (a) used in the present invention, the circular space portion (103a) so that the wall thickness of the cylindrical housing (100a) is constant. ) Is formed in the center of the cylindrical housing (100a) and the rotating body 110 is eccentrically mounted in the center of the circular space portion 103a, the rotating body 110 arranged in the circular space portion (103a) is eccentric In this state, when the steel ball 114 of the rotating body 110 is in contact with the inner wall of the circular space portion 103a when the rotating body 110 is rotated, a strong elastic force of the spring 116 is received. As the 114 is moved away from the inner wall of the circular space 103a, the spring 116 receives a weak elastic force, thereby controlling the opening and closing speed of the door.

The opening and closing force control means of the door of the present invention having the above-described configuration and action effect is to eccentric the rotating body in the circular space formed eccentrically in the cylindrical housing by placing the rotating body using a spring with a constant elastic force in the cylindrical housing Steel that is resilient or formed in a circular space at the center of the cylindrical housing to eccentrically rotate the rotating body in the circular space, so that the steel is subjected to spring force when the door is closed and the distance between the rotating body and the housing inner wall is closest As the ball is in close contact with the door, the supporting force of the door is increased and the door is opened, and the inner axis of the rotor and the inner wall of the housing gradually move away. As the spring elasticity weakens, the door opens lightly and the door is returned by the door return spring. When the door closes, the spring's elasticity gradually becomes stronger, Because it closes tightly, accidents caused by hitting or pinching the door can be prevented in advance.

In addition, the present invention is to achieve the advantage that the door opening and closing force control structure is very simple, easy to manufacture, low failure rate and significantly lower production cost.
