At present, in many places (such as apartments, offices or elevator buildings, etc.), most of the installation methods of the various doors use only the pivoting structure, which simply provides the relative connection and pivoting of the door frame and the door leaf. After the user opens the door leaf, because the door leaf is not positioned and restricted by any device structure, the door leaf will freely swing back and forth due to the external force of the user to open the door leaf. Moreover, if the external force of the door leaf is too large, it may collide. Set one of the wall surfaces on both sides of the door frame, and so on.

In response to the above problems, a hinge structure capable of automatically closing the door has been developed. In other words, after the door leaf is opened, the user exerts a force on the door leaf, and the hinge structure of the door leaf automatically reacts to generate a reaction force. When the external force of the door leaf is removed, the reaction force of the hinge structure will cause the door leaf to slowly close to the door frame. So the user does not have to worry about the door not closing. Moreover, the reaction force of the hinge structure can also slightly reduce the force of opening the door leaf to avoid the force of opening the door leaf too strong and colliding with the wall surface.

Please refer to the third figure, which is a cross-sectional view of the hinge structure of the present invention. As shown, the first fixing module 10 includes a first fixing member 11 and a first locking member 12. The first fixing member 11 has a first fixing portion 111 and at least one first socket portion 112. In the embodiment, the first fixing portion 111 has a sheet structure. The at least one first socket portion 112 may include two first socket portions 112, and the two first socket portions 112 are extended from the two ends of the first fixing portion 111 to each other in a vertical direction. The bending is in the form of a collar, and the sleeves of the sleeves at both ends correspond to each other. The at least one first socket portion 112 is disposed on one side of the first fixing portion 111. The first locking member 12 has a first locking portion 121 , and the first locking portion 121 has two protrusions 1211 . The first locking member 12 has a sleeve hole of the at least one first socket portion 112 at one end of the first locking portion 121 .

Furthermore, the second fixing module 20 includes a second fixing member 21 and a second locking member 22 . The second fixing member 21 has a second fixing portion 211 and a second socket portion 212. In this embodiment The second fixing portion 211 has a sheet-like structure, and the second socket portion 212 is bent inward by the second fixing portion 211 to form an annular body. The second locking portion 22 has a second locking portion 221 , and the second locking portion 221 has the same shape as the first locking portion 121 and has two convex portions 2211 . The second locking member 22 is disposed in the sleeve hole of the second socket portion 212 , and the second locking portion 221 is opposite to the first locking portion 121 .

The second fixing module 20 is disposed on the first fixing module 10, that is, the two ends of the sleeve hole of the second socket portion 212 respectively correspond to the sleeve holes of the two first socket portions 112, in other words, the second portion The sleeve hole of the socket portion 212 is located between the two first socket portions 112. Moreover, a bearing 50 is respectively disposed between the two first socket portions 112 and the second socket portion 212. The first locking member 21 is disposed through the first socket portion 112 , the bearing 50 and the second socket portion 212 .

The elastic pivoting member 30 is disposed in the second socket portion 212. One end of the elastic pivoting member 30 is connected to the first locking portion 121 of the first locking member 12 and is fixed between the two protruding blocks 1211. The other end of the elastic pivoting member 30 is coupled to the second locking portion 221 of the second locking member 22 and is fixed between the two convex portions 2211. The elastic pivoting member 30 of this embodiment may be a spring.

The positioning module 40 has at least two positioning rings 41 and at least two elastic positioning members 42. The at least two positioning rings 41 have a plurality of positioning holes 410 , and the at least two positioning rings 41 are stacked on the inner wall of the sleeve hole of the second socket portion 212 . The holes of the positioning holes 410 of the at least two positioning rings 41 are arranged asymmetrically in the upper and lower directions, that is, when the positioning ring 41 located above has one of the positioning holes 410, the positioning is relative to the positioning holes 410. The opposite regions of the positioning ring 41 directly below one of the holes 410 do not have the plurality of positioning holes 410. Moreover, the at least two elastic positioning members 42 respectively correspond to the at least two positioning rings 41, and the upper and lower portions are arranged on the first locking member 12. The at least two positioning rings 41 are designed with the holes of the positioning holes 410, and can be designed relatively freely, and the design is difficult because the aperture size or the positioning angles of the adjacent positioning holes 410 are too small. . Regarding the structural design of the positioning module 40, the number of positioning rings or the number of positioning holes can be adjusted according to the needs of the user.

Please refer to FIGS. 4A to 4B together, which are schematic diagrams 1 to 3 of the operation of the hinge structure of the present invention. As shown, each of the elastic positioning members 42 further includes an elastic unit 421 and a spherical unit 422. The ball unit 422 is disposed at one end of the elastic unit 421 , and the other end of the elastic unit 421 is disposed at the first lock 12 . Thus, the spherical unit 422 is affected by the compressed reaction force of the elastic unit 421, so that the spherical unit 422 can continue to abut against the inner annular surface of the two positioning rings 41, and the inner annular surface has the positioning holes. 410. When one of the at least two elastic positioning members 42 corresponds to the one of the at least two positioning rings 41, the spherical elastic force of the elastic unit 421 acts on the spherical unit 422, and the spherical unit 422 is embedded in the corresponding positioning hole. One of the 410s, such that the at least two elastic positioning members 42 may have an effect of restricting movement with respect to the at least two positioning rings 41.

As described above, the present embodiment is further illustrated by the positioning module 40. The positioning ring 41 has the positioning holes 410 corresponding to the angles of thirty degrees, sixty degrees, and ninety degrees. The positioning ring 41 below has the positioning holes 410 corresponding to the angles of fifteen degrees, forty-five degrees and seventy-five degrees. The positions of the positioning holes 410 of the two positioning rings 41 are upper and lower asymmetrical. In this embodiment, the upper elastic positioning member 42 can be fixed at a position of thirty degrees, sixty degrees and ninety degrees, and the lower elastic positioning member 42 can be used for an angle of fifteen degrees. Cards are fixed at positions of forty-five degrees and seventy-five degrees. The upper and lower asymmetric design manners of the positioning holes 410 of the at least two positioning rings 41 can further subdivide the positioning angle between the first fixing module 10 and the second fixing module 20 .

In the embodiment, when the door leaf is opened (that is, the door leaf is pivoted relative to the door frame), the first fixing module 10 pivots relative to the second fixing module 20. The ball unit 422 of the at least two elastic positioning members 42 is moved against the positioning holes 410 of the at least two positioning rings 41. The limiting force of the at least two elastic positioning members 42 relative to the positioning holes 410 of the at least two positioning rings 41 is not sufficient to affect the positioning of the door leaf. Open the door Then, the user can position the door opening angle according to the state of use, and the door unit is opened until the spherical unit 422 of the at least two elastic positioning members 42 is embedded in the positioning holes 410 of the at least two positioning rings 41. Thus, the upper and lower asymmetric design manners of the at least two elastic positioning members 42 relative to the plurality of positioning holes 410 of the at least two positioning rings 41 enable the door leaf to have more positioning opening angles relative to the door frame.

Moreover, since the elastic pivoting member 30 has been pivotally pressed by the first fixing module 10 and the second fixing module 20 in a horizontal direction, the elastic pivoting member 30 has a reaction force (ie, elastic restoring force). ). When the door leaf is to be closed (ie, the door leaf coincides with the door frame), the reaction of the door leaf through the elastic pivoting member 30 allows the door leaf to automatically overlap with the door frame for closing.

This embodiment is directed to improving the shortcomings of the prior art. In the prior art, the positioning structure of the hinge structure is simple, and the angle at which the door leaf and the door frame are positioned to be opened is small, and the door leaf is opened in accordance with the user's requirement. Positioning angle. Therefore, the present embodiment provides a hinge structure 1 that is designed through the structure of the positioning module 40. The at least two elastic positioning members 42 have a plurality of positioning angles for opening the door relative to the at least two positioning rings 41. Furthermore, the first fixing module 10 and the second fixing module 20 have the elastic pivoting member 30. When the door leaf is opened, the first fixing module 10 is horizontally pivoted relative to the second fixing module 20. In turn, the elastic pivoting member 30 generates a reaction force (ie, elastic restoring force). When the door leaf is closed, the door leaf is no longer affected by the external force, and the reaction force of the elastic pivoting member 30 overlaps the door leaf to the door frame.

Referring to the second and third figures, the embodiment further includes a fixing bolt 60 and a plurality of adjusting holes 61. The adjusting holes 61 are disposed on the first locking member 111. The at least one first socket portion 12 is disposed with a fixing hole 123 corresponding to the horizontal height of the adjusting holes 61. The fixing pin 60 passes through the fixing hole 60. The fixing hole 123 is embedded in one of the adjustment holes 61. The end of the fixing bolt 60 has a thread, and the inner wall of the adjusting hole 61 has a corresponding internal thread and is located at the bottom of the hole. The fixing bolt 60 is screwed and fixed to one of the adjusting holes 61, and the fixing bolt 60 is further completely embedded in the fixing bolt 60. The fixing pin 60 does not affect the pivoting of the first fixing module 10 relative to the second fixing module 20 in the first socket portion 12 of the first fixing module 10 . Moreover, the first embodiment has a vertical limiting slot 125 and a vertical limiting member 127. The vertical limiting slot 125 is disposed on the first locking member 111, and the at least one first socket portion 12 corresponds to the A vertical limiting hole 129 is defined in the vertical limiting slot 125. One end of the vertical limiting member 127 extends through the vertical limiting hole 129 and protrudes from the vertical limiting slot 125.

In the embodiment, the first locking member 111 is disposed through the at least one first socket portion 12, and the limiting member 127 is disposed through the limiting hole 129 of the first socket portion 12 to be protruded. In the limit slot 125. Thus, the vertical height position of the first locking member 111 is limited, and only the horizontal rotation can be performed. In other words, during the rotational movement of the first locking member 111, one end of the limiting member 127 is always maintained at the same. Within the slot 125. Moreover, after the first locking member 111 is horizontally rotated, it can interlock one end of the elastic pivoting member 30, so that the elastic pivoting member 30 is horizontally pivoted, thereby adjusting the initial elastic compression state of the elastic pivoting member 30. After the adjustment, the fixing bolt 60 is inserted through the fixing hole 123 and embedded in one of the adjusting holes 61 for fixing.

As described above, since the elastic pivoting member 30 has been firstly compressed and adjusted by the fixing bolt 60 and the adjusting hole 61, when the first fixing module 10 and the second fixing module 20 are pivoted, The elastic pivoting member 30 is again horizontally compressed by the first fixing module 10 and the second fixing module 20, so that the reaction force (ie, the elastic restoring force) generated by the elastic pivoting member 30 is large. In this embodiment, the reaction force of the elastic pivoting member 30 can be adjusted according to the user's needs (such as the weight of the door leaf), so that the door leaf can be subjected to the reaction force of the elastic pivoting member 30, and the door leaf and the door frame are automatically overlapped.

Please refer to the fifth figure, which is a partially exploded schematic view of the hinge structure of the present invention. As shown in the figure, in the embodiment, the buffer module 70 is disposed in a sleeve hole of the second socket portion 212. The buffer module 70 includes an elastic member 71. a mortgage 73, a slip The moving member 75 and the body 77. The elastic member 71 can be a spring having one end abutting against the second locking member 22 and the other end abutting against one side of the mortgage member 73. The other side of the mortise member 73 has a fitting portion 731 protruding from a portion of the sliding member 75. One side of the mortgage 73 has a horizontal limiting slot 733 and a horizontal limiting member 735. The at least one first socket portion 12 is disposed with a horizontal limiting hole 737 corresponding to the position of the horizontal limiting slot 733. The horizontal limiting member 735 extends through the horizontal limiting hole 737 and protrudes from the horizontal limiting slot 735 . This can limit the fact that the mortgage 73 cannot be horizontally rotated while maintaining the vertical movement of the mortgage 73.

Further, the seat body 77 has a sliding groove 771 with respect to the fitting portion 731 of the mortgage member 73. The chute 771 is disposed on the top surface of the seat body 77. The height of the sliding groove surface of the sliding groove 771 is gradually changed. In other words, the sliding surface of the sliding groove 771 is gradually higher or gradually shorter than the height of the surface of the reinforcing member 73 having the fitting portion 731. In this embodiment, before the first fixed module 10 and the second fixed module 20 are pivoted, the sliding groove surface of the sliding slot 771 is at a maximum distance from the mortgage 73, that is, the mortgage The force of 73 relative to the chute surface of the chute 771 is minimal. The greater the angle at which the first fixed module 10 and the second fixed module 20 are pivoted, the smaller the interval between the sliding surfaces of the sliding slot 771 and the collateral 73, that is, the collateral 73 relative to The sliding groove surface of the chute 771 has the largest force.

As described above, when the door leaf is subjected to the reaction force of the elastic pivoting member 30, and the door leaf automatically overlaps the door frame, if the reaction force of the elastic pivoting member 30 is too large, the force of the door leaf overlapping the door frame may be too large, possibly The door leaf and the door frame collide with each other to cause damage or noise. Therefore, the buffer module 70 of the embodiment can slow down the speed and force of the door leaf overlapping the door frame. When the door leaf is automatically overlapped with the door frame, the first fixing module 10 and the second fixing module 20 are pivoted by the reaction force of the elastic pivoting member 30, and the collateral of the buffer module 70 The change of the pressing force is caused by the pivoting angle of the blade 73. When the relative angle of the first fixing module 10 relative to the second fixing module 20 is larger, the sliding of the seat body 77 is performed. Height of the slot 771 It is high, and the urging member 73 is pressurized to the sliding member 75 to abut against the sliding groove 771 of the seat body 77. When the elastic pivoting member 30 pushes the first fixing module 10 and the second fixing module 20 by a reaction force, the elastic pivoting member 30 receives a large resistance.

On the contrary, when the relative angle of the first fixing module 10 relative to the second fixing module 20 is smaller, the height of the sliding slot 771 of the seat body 77 is low, and the mortgage member 73 is pressed against the sliding member. The force acting on the chute 771 of the seat body 77 is small. When the elastic pivoting member 30 pushes the first fixing module 10 and the second fixing module 20 by a reaction force, it will receive less resistance. When the above-mentioned manner can force the first fixed module 10 and the second fixed module 20 to automatically return to coincide with each other, the pivoting speed thereof is slowed down by the buffer module 70.

Moreover, the elastic member 71 is also compressed and changed along with the height of the sliding surface of the mortise member 73 with respect to the sliding groove 771. When the height of the sliding groove surface of the sliding groove 771 is high, the interval of the mortgining member 73 relative to the second locking member 22 is small, that is, the elastic member 71 is compressed, and the elastic member 71 correspondingly generates a reaction force. The elastic reaction force of the elastic member 71 facilitates the pivoting of the first fixed module 10 relative to the second fixed module 20 to cause the door leaf to coincide with the door frame. On the other hand, when the height of the sliding groove surface of the sliding groove 771 is low, the interval between the securing member 73 and the second locking member 22 is large, that is, the elastic member 71 is not compressed, and no corresponding reaction occurs. force.

In addition, in the embodiment, a buffer adjustment module 81 is further included. The buffer adjustment module 81 includes a buffer adjustment member 83, an adjustment block 85, an elastic body 87 and a fixing member 89. The cushioning member 83 passes through the seat body 77 to correspond to the lower side of the securing member 73. One end of the fixing member 89 passes through the seat body 77 and is secured to one side of the cushioning adjusting member 83. The adjusting block 85 is disposed on the buffer adjusting member 83. One end of the elastic body 87 is further disposed on the adjusting block 85, and the other end thereof abuts against the mortgage member 73. The adjustment block 85 can be adjusted according to the needs of the user with respect to the buffer. The height of the adjusting member 83 increases or decreases the reaction force of the elastic body 87 against the mortgage member 73.

In this embodiment, the buffer adjusting member 83 is pivoted, and the height of the adjusting block 85 relative to the buffer adjusting member 83 is adjusted, thereby changing the reaction force of the elastic body 87, so that the mortgage member 73 can be relatively adjusted. The urging force of the sliding member 75 against the sliding groove 771 of the seat body 77 is adjusted, and the damping force of the buffer module 70 is adjusted.

The locating holes 410 of the two positioning rings 41 of the positioning module 40 have a plurality of aperture sizes. When the first fixing module 10 and the second fixing module 20 are pivoted, the spherical unit 422 of each of the elastic positioning members 42 can be stably abutted against the positioning holes 410 of the two positioning rings 41. When the ball unit 422 is moved against the plurality of positioning holes 410 having a small aperture, the positioning limit generated by the plurality of positioning holes 410 having a small aperture is insufficient to stop the pivotal movement of the first fixing module 10. . However, the pivoting of the first fixed module 10 relative to the second fixed module 20 is hindered. This manner also helps to slow the pivoting speed of the first fixed module 10 and the second fixed module 20, and also reduces the reaction force (ie, elastic restoring force) of the elastic pivoting member 30.

In summary, the hinge structure of the present invention can provide a plurality of positioning angles through the positioning module, so that the door leaf is maintained at the same opening angle after the door leaf is opened. After the external force is applied to pivot the first fixed module and the second fixed module, when the external force disappears, the elastic member has an automatic return to the first fixed module and the second fixed module. The function of the angle before the turn.

Moreover, the hinge structure has a pivoting speed and a lowering pivoting force for buffering the automatic pivoting recovery of the first fixed module and the second fixed module. In addition, the user can adjust the pivoting force of the hinge structure according to the user's needs.

It can be seen from the above that the present invention has indeed achieved a breakthrough structure, and has improved invention content, and at the same time, can achieve industrial utilization and progress. When complying with the provisions of the Patent Law, the new patent application is filed according to law. The Board of Review examiners granted legal patent rights and was praying.
