Problems solved by technology
[0003] Traditional sky and earth hinges usually do not necessarily have the design of the back resistance function. The back resistance function is to allow the door panel to obtain a cushioning effect when opening the door, so as to avoid damage to the door panel or glass door due to excessive force when opening the door , but the size of the back resistance of the traditional heaven and earth hinge is fixed and cannot be adjusted. In this case, the same back resistance effect may be too small for a strong person, but may be too large for a weak person. Therefore, There is no way to adjust the back resistance for different usage conditions in the traditional world hinge, and the applicability needs to be improved

Embodiment Construction
[0021] Please see first figure 1 and figure 2 , is a heaven and earth hinge 10 of a preferred embodiment of the present invention, including a base 20, a shaft unit 30, two damping units 40, two flow adjustment valves 50a, 50b, a back resistance adjustment valve 60, and a check valve 70 , and two relief valves 80.
[0022] Please refer to Figure 2 to Figure 4 , the base 20 is elongated, and has an oil storage space 21 for storing hydraulic oil and an oil guide channel 22 connected to the oil storage space 21 inside it, and penetrates from the top surface of the base 20 to connect with the oil guide channel 22 communicates with two first adjustment holes 23a, 23b and a second adjustment hole 24 . The oil guide passage 22 has a first section 221, a second section 223 below the first section 221, a third section 225 above the second section 223, and a section between the first section 221 and the third section 225. The steel ball 227 between them is used to block the first ...

The invention relates to a pivot hinge capable of adjusting back resistance, mainly comprising a base, a rotary shaft unit arranged on the base, two damping units connecting the rotary shaft unit, two flow adjusting valves arranged on the base, and a back resistance adjusting valve arranged on the base. The rotary shaft unit makes use of a thrust of opening a door to rotate and drives the damping units to move during the rotating process. Meanwhile, different back resistance values provided by the back resistance adjusting valve make buffer forces of opening the door be adjusted on the basis of different status. When the thrush or pull on the door disappears, the door is gradually closed by the driving of the damping units. And in the closing process, the door-closing rate is controlled by tightness of the flow adjusting valves.
Description
technical field [0001] The present invention relates to a sky-earth hinge, in particular to a sky-earth hinge with adjustable back resistance. Background technique [0002] At present, the door panel is connected to the door frame by an exposed door closer or a concealed door closer, so that the door panel can rotate relative to the door frame to achieve the purpose of opening or closing the door. As far as the hidden door closer (such as the heaven and earth hinge) is concerned, a rotating shaft is mainly used to connect with the door panel. The rotating shaft can be rotated by the thrust when the door is opened, and drives a damping unit to move during the rotation. Once the door panel is subjected to After the thrust disappears, the spring return force provided by the damping unit will force the rotating shaft to reverse to drive the door panel to close. [0003] Traditional sky and earth hinges usually do not necessarily have the design of the back resistance function. ...
