Furthermore, the concrete method by which a screw passes through the left through hole (1124) and is screwed into the left threaded hole (1112) is as follows: the two left through holes (1124) are inwardly concave left stepped holes, which correspond to the head of the step screws (24) are embedded, the step screws (24) and the left stepped holes forming a cooperating structure which is rotatably connected and moves synchronously in the axial direction, the step screw (24) passing through the right stepped hole and is screwed into the left threaded hole (1112); the concrete procedure is as follows for a screw to pass through the right through hole (2124) and be screwed into the right threaded hole (2112):

• the two right through holes (2124) are long inwardly concave right stepped holes, and a screw (14) passing through the right through hole (1124) and
• screwed into the right-hand threaded hole (2112) is used., the right-hand bracket (212) being accommodated in the cavity of the right-hand shell (211) by creating a longitudinal gap between the right-hand bracket and the cavity of the right-hand shell (211). is available.

As in the 12 until 15 and 20 As shown, the inner stepped round hole is inserted through the thick end of the eccentric shaft with a notch located on the thick end face. Due to the internal gradation, the end face of the round hole has a small diameter and the inner hole has a large diameter, so the eccentric shaft cannot be separated from the round hole. When a tool is inserted through the small hole on the inner stepped round hole into the notch on the eccentric shaft, the eccentric shaft can be rotated. Because the left large bracket is placed in the cavity of the left shell, there is not much gap between the left large bracket and the left shell in the width direction of the left shell, therefore, when the thick end of the eccentric shaft is rotated, the rotation of the thin cylinder becomes the driven by a long groove inserted by the eccentric shaft. This allows the left large bracket to be moved longitudinally of the cavity of the left shell where the long groove is located. When loosening the screws, the relative position of the left large bracket to the left shell can be shifted. If the left shell is longitudinally higher than the right shell, it means that the door panel connected to the left shell rises in the vertical direction, and the left large bracket can move down, with the relative position to the right bracket remaining unchanged. The door frame connected to the right shell, on which the right bracket is located, does not need to be additionally slotted and loose leaf mounted, so that the door leaf can be adjusted up and down, changing the size of the upper and lower door gaps between the door leaf and the door frame will.

As in the 16 until 19 and 10 further, the concrete method for embedding the other end of the first eccentric shaft (50) in the long groove (1113) is as follows: the other end of the first eccentric shaft (50) is mit a block mounted slider (501) embedded in the long groove (1113). Adjusting the slider on the thin end of the eccentric shaft is to prevent excessive point contact with the long groove by the end of the eccentric shaft. Point contact is easy to wear parts, and the slider causes the contact between them to become surface contact, on the contrary, surface contact is not easy to wear parts.

Embodiment III

The principle is the same as the previous embodiment, when the tool is inserted into the notch on the eccentric shaft, the eccentric shaft can be rotated, then the left small bracket (113) into the left large bracket (112) with a gap to Cavity of the left housing (111) embedded in the width direction. When the thin end of the eccentric shaft is rotated, since the left large bracket in the width direction is almost pinched by the cavity of the left shell, then it is shown that the left small bracket where the long hole is located is driven to move in To move width direction of the cavity of the left shell. When the left shell is offset from the right shell in the width direction, it means that the door panel connected to the left shell is adjusted forward and backward, and the left large bracket can move forward and backward, with the left large bracket moving forward and can move backwards and the relative position to the right bracket remains unchanged. Thus, the door frame connected to the right shell, on which the right bracket is located, does not need to be additionally slotted and assembled with loose leaf, so that the front and rear adjustment of the door leaf and the change of the front and rear relative position of the door leaf and door frame are accomplished will.

The above realization of the up and down movement of the door panel to change the size of the upper and lower door gaps between the door panel and the door frame, and the realization of the forward and backward movement of the door panel to change the size of the front and rear relative position of the door panel and the door frame has the advantage that users no longer need to make extra slots on the door leaf or door frame and pay extra service fees for such adjustments.

Furthermore, the concrete method of firmly connecting one end of the functional axis (23) to one of the right lower through holes (2126) is as follows: the upper end of the central axis (9) protruding from the upper nozzle of the outer sleeve (231) through a Adapter sleeve is firmly connected to one of the lower right through holes (2126).
In addition, the concrete method of rolling connection of the other end of the right functional axis (23) with the other lower right through hole (2126) is as follows: the reduced diameter portion (831) of the lower cover (83) is through a rolling bearing with the other lower through hole (2126) connected.

Furthermore, the functional axis (23) also includes a hydraulic buffer mechanism.

Further, the specific structure of the hydraulic buffer mechanism is as follows: a check valve (822) is arranged at the cylinder bottom of the piston (82), between the outer wall of the top cover (81) and the inner wall of the outer sleeve (231), between the inner hole wall of the a first sealing ring (62) and a second sealing ring (63) are provided on the upper cover (81) and on the outside of the central axis cylinder (9), the horizontal axis cylinder (92) being equipped with an annular sliding sleeve (84). and wherein the outer tubular body of the outer sleeve (231) is provided with an annular sealing sleeve (64) which (64) covers the two insertion holes (61) of the horizontal axis, wherein between the sealing sleeve (64) and the outer sleeve (231) there is a upper sealing ring (65) and a lower sealing ring (66) are arranged, which are respectively above and below the horizontal axis (92), being between the outer wall of the lower cover (81) and the inner wall of the outer sleeve a third sealing ring (67) is arranged, and wherein the inner hole of the lower cover is screwed with a cylindrical oil needle for speed adjustment (85), the upper cylinder of the oil needle for speed adjustment (85) in the inner hole of the cylinder bottom of the piston (82), with a fourth sealing ring (68) being interposed between the outer part of the lower cylinder of the oil needle for speed regulation (85) and the inner hole wall of the lower cover (83), between the outer wall of the cylinder body of the piston (82) and the inner wall of the outer sleeve (231) a fifth seal ring (69) is provided, wherein the space between the lower end surface of the check valve (822) and the inner end surface of the lower cover (83) has a pressure oil chamber (600). wherein the space between the upper end surface of the check valve (822) and the inner end surface of the top cover (81) has an oil storage cavity (601). is.

The shell on one side of the adjustable hinge is embedded on the door frame and that on the other side on the door leaf. When the door leaf is closed, the inner cross-section of the hinge is in the 3 and 7 shown with the left and right shells facing each other. The end of the small support arm, in which the drive shaft is embedded, is near the bottom of the right bracket, with the connected function shaft in the unloading state, and the inner piston is near the bottom cover. When the user opens the door leaf, as in the 4 6 and 8, the left and right housings are relatively separated along the central axis. In the large and small support arms articulated by the central axis, one end of the large support arm is mounted on the right fixed axis of the right bracket, the position remains unchanged and it rotates around it. The other end is pulled out. At this time, the large bracket drives the small bracket to pull out through the central axis, and the small bracket connects the punched rocker arm through the drive shaft. As a result, the perforated rocker arm and the outer sleeve of the functional shaft rotate outwards along the axis of the functional shaft, with the horizontal axis also following the rotation with the heads embedded on both sides in the outer sleeve of the functional axis. The horizontal axis slips in the inclined portion of the piston to move the piston up in the axial direction. The piston moves up in the axial direction and presses the compression spring to store energy. The valve body of the rear The check valve leaves the bottom of the piston cylinder and the check valve forms a passage, so the hydraulic oil in the functional shaft flows through the check valve from the oil storage chamber to the pressure oil chamber. When the external force to open the door is completely eliminated, the compression spring releases the pressure to push the piston forward, and the horizontal axis rotates under the action of the inclined section of the spiral sliding groove of the piston, which causes the outer sleeve and the perforated rocker arm to rotate to reset, the perforated rocker arm pulling the support arm through the drive shaft to reset inward and realize automatic closing. Because the valve body of the check valve and the piston form a seal when the piston returns and moves down, so the hydraulic oil in the pressure oil chamber flows through the gap between the speed control oil needle and the oil hole at the bottom of the piston tube. Adjusting the insertion amount of the speed control oil needle changes the size of the gap between the speed control oil needle and the oil passage of the piston, so that the hydraulic oil flow from the pressure oil chamber to the oil storage chamber and the downward speed of the piston can be controlled to realize adjustable buffer closure.

When the horizontal shaft slides to the horizontal portion of the spiral sliding groove of the piston, the piston does not move axially and the pressure released by the compression spring cannot drive the horizontal shaft. Therefore, the hinge can remain in this situation. A bayonet is opened in the horizontal section to engage the horizontal axis, and the hinge has a door stop function in this angle as well.
