Therefore, the use of hinges directly affects the user experience. Simple hinges usually do not have the function of a door stopper. After the adjustment plate is opened and abuts against the wall, a bumper pad or a suction nozzle needs to be set for fixation. Therefore, currently, by arranging a spring, a clamping block and a clamping groove inside the hinge, when the hinge rotates a certain angle, the clamping block aligns with the clamping groove, and at this time, the spring drives the clamping block into the clamping groove, thereby realizing the temporary fixation of the hinge and further realizing the function of a door stopper.

[0003] In the aforementioned prior art, although the hinge can be limited in position through the cooperation of the clamping block and the clamping groove to achieve the function of a door stopper, the position of the cooperation between the clamping block and the clamping groove cannot be changed, resulting in the hinge always being limited at a fixed angle, that is, the angle of the door stopper cannot be adjusted, which is not convenient for users to use freely and affects the use experience.

Detailed implementation manners

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0031] Please refer to Figures 1 to 11The present invention provides a hinge capable of adjusting the angle without door suction, comprising two first rotating members 1, two second rotating members 2 and an adjusting assembly, wherein the adjusting assembly comprises a connecting block 3, two threaded columns 4, two first threaded blocks 5, a plurality of quick-release buckles 6 and a plurality of rebound units, wherein the first threaded block 5 has a card slot 7, the adjusting assembly further comprises an intermediate housing 8, two connecting shafts 9, two first slide grooves 10, two first sliders 11 and two automatic rotation units, wherein the automatic rotation unit comprises a torsion spring 13, a cross limit groove 14, a cross limit block 15, a rotating column 16, a telescopic shaft 17, two contraction mechanisms and a first locking mechanism, wherein the contraction mechanism comprises a contraction plate 18, a contraction spring 19 and a contraction rod 20, wherein the first locking mechanism comprises a first top moving inclined block 21, a first A threaded rod 22, a second threaded block 23 and a first turning handle 24, the telescopic shaft 17 has an annular bevel groove 25, the rebound unit includes a support shell 26, a moving block 27, a rebound spring 28, a holding spring 29, a holding rod 30, an anti-slip plate 31, a stabilizing mechanism and a second locking mechanism, the stabilizing mechanism includes a second slider 32 and a second slide groove 33, the second locking mechanism includes a second turning handle 34, a second threaded rod 35 and a second pushing bevel block 36, the support shell 26 has a threaded hole 37, the moving block 27 has a bevel groove 38, the adjustment assembly also includes an adjusting plate 39, a handle 40, a limiting groove 41, an oblique clamping block 42 and a toggle mechanism, the toggle mechanism includes a toggle block 43, a telescopic rod 44, a toggle block contraction spring 45, and the intermediate shell 8 has a slot 46.

[0032] Among them, the first rotating member 1 is rotatably connected to the corresponding second rotating member 2, the first threaded block 5 has a slot 7, the connecting block 3 is located between the two second rotating members 2, the two threaded columns 4 are symmetrically arranged at both ends of the connecting block 3, the two first threaded blocks 5 are respectively adapted to the corresponding threaded columns 4, a plurality of rebound units are sequentially arranged on one side of the threaded column 4, the quick-release buckle 6 is arranged on the rebound unit, and the quick-release buckle 6 is adapted to the slot 7. The first rotating member 1 and the second rotating member 2 are installed on the door to realize the rotation function of the door. When the door drives the first rotating member 1 and the second rotating member 2 to rotate, the first rotating member 1 will drive the threaded column 4 and the connecting block 3 to rotate, and the two threaded columns 4 drive the two first threaded blocks 5 to move relative to each other, thereby driving the slot 7 to move continuously. After moving to the side of the quick-release buckle 6, due to the action of the rebound unit, the quick-release buckle 6 enters the slot 7, thereby realizing the limiting of the door panel. At the same time, the user continues to push the door panel to disengage the quick-release buckle 6 from the slot 7, and then makes the slot 7 continue to cooperate with the quick-release buckle 6 at the next position, thereby realizing door suction-free limiting at different angles.

[0033] Secondly, the intermediate housing 8 is disposed between the two second rotating members 2. A plurality of the resilient units and the two threaded columns 4 are all located inside the intermediate housing 8. The two connecting shafts 9 are respectively rotatably connected to the corresponding second rotating members 2. The two first rotating members 1 are respectively fixedly connected to the corresponding connecting shafts 9 and sleeved on the outer wall of the connecting shafts 9. One end of the connecting shaft 9 penetrates through the second rotating member 2 and the intermediate housing 8 and is fixedly connected to the threaded column 4. The second rotating member 2 has a rotary chamber 12. The other end of the connecting shaft 9 is located inside the rotary chamber 12. The automatic rotary unit is disposed at the other end of the connecting shaft 9. The two first chutes 10 are symmetrically disposed inside the intermediate housing 8. Both ends of the two first sliders 11 are respectively fixedly connected to the corresponding first chutes 10 and the corresponding first threaded blocks 5. The intermediate housing 8 is used to protect the internal components and connect the two second connecting members. When the first connecting member rotates, it drives the connecting shaft 9 to rotate, and further drives the automatic rotary unit to operate through the connecting shaft 9, so that when the door suction function is not enabled, the door panel can be automatically closed by relying on the automatic rotary unit. In addition, when the first threaded block 5 moves, the first slider 11 slides in the first chute 10 to maintain stability.

[0034] Meanwhile, the torsion spring 13 is disposed inside the rotary chamber 12. The cross-shaped limiting groove 14 is disposed at one end of the torsion spring 13. The rotating column 16 is fixedly connected to the other end of the connecting shaft 9 and is rotatably connected to the rotary chamber 12. The telescopic shaft 17 is slidably connected to the rotating column 16. The cross-shaped limiting block 15 is disposed at one end of the telescopic shaft 17. The two contraction mechanisms are symmetrically disposed outside the telescopic shaft 17. The first locking mechanism is disposed on the second rotating member 2. When automatic rotation is required, first start the first locking mechanism to drive the telescopic shaft 17 to extend out of the inside of the rotating column 16, so that the cross-shaped limiting groove 14 cooperates with the cross-shaped limiting block 15. At this time, the connecting shaft 9 and the first rotating member 1 are connected to the torsion spring 13. Then, after the user releases the door panel, the torsion spring 13 can be reset to automatically close the door panel.

[0035] In addition, the contraction plate 18 is arranged outside the telescopic shaft 17. Both ends of the contraction spring 19 are movably connected to the contraction plate 18 and the inner wall of the telescopic shaft 17 respectively. Both ends of the contraction rod 20 are fixedly connected to the contraction plate 18 and the inner wall of the telescopic shaft 17 respectively. The contraction rod 20 is located inside the contraction spring 19. When the automatic rotation function is not required, the first locking mechanism releases the locking, and then the contraction spring 19 drives the contraction plate 18 to contract, so that the telescopic shaft 17 returns to the inside of the rotating column 16, the cross-shaped limiting block 15 is separated from the cross-shaped limiting groove 14, and at the same time the contraction rod 20 follows the telescoping to maintain stability.

[0036] Then, the telescopic shaft 17 has an annular inclined groove 25. The first pushing inclined block 21 is adapted to the annular inclined groove 25. The second threaded block 23 is arranged on the inner wall of the rotary bin 12. The first threaded rod 22 is rotatably connected to the second rotating member 2. The first threaded rod 22 is adapted to the second threaded block 23. Both ends of the first threaded rod 22 are fixedly connected to the first pushing inclined block 21 and the first rotating handle 24 respectively. When extending the telescopic shaft 17, rotate the first rotating handle 24 to drive the first threaded rod 22 to cooperate with the second threaded block 23, and then drive the first pushing inclined block 21 into the annular inclined groove 25. As the first pushing inclined block 21 moves, the telescopic shaft 17 is pushed out of the rotating column 16, so that the cross-shaped limiting block 15 enters the cross-shaped limiting groove 14. At this time, the connecting shaft 9 and the torsion spring 13 can be connected as a whole. When the connecting shaft 9 rotates, the first pushing inclined block 21 slides synchronously in the annular inclined groove 25 and always keeps limiting and holding the telescopic shaft 17 to prevent the cross-shaped limiting block 15 from disengaging.

[0037] Again, the support shell 26 is arranged on the inner wall of the middle shell 8, the stabilizing mechanism is arranged inside the support shell 26, the moving block 27 is arranged on the stabilizing mechanism, the second locking mechanism is arranged on the support shell 26 and the moving block 27, one end of the abutting rod 30 is fixedly connected to the quick-release buckle 6, the other end of the abutting rod 30 is slidably connected to the support shell 26 and is fixedly connected to the anti-disengagement plate 31, two ends of the return spring 28 are respectively movably connected to the inner side wall of the support shell 26 and one end of the moving block 27, and two ends of the abutting spring 29 are respectively movably connected to the other end of the moving block 27 and the anti-disengagement plate 31. The support shell 26 is used for supporting and protecting internal components. When the second locking mechanism operates, it can drive the moving block 27 to move inside the support shell 26, and at the same time the stabilizing mechanism maintains the moving stability of the moving block 27; when the moving block 27 moves to the left, the abutting spring 29 is stretched, and at the same time the return spring 28 contracts. At this time, the return spring 28 can generate a greater return force, driving the abutting rod 30 and the quick-release buckle 6 into the card slot 7. If the user wants to reduce the tightness of the fit between the quick-release buckle 6 and the card slot 7, the moving block 27 can also be moved to the right, causing the return spring 28 to be stretched, reducing its return force, and reducing the tightness of the fit between the quick-release buckle 6 and the card slot 7, thereby adjusting the locking force of a certain door-free suction angle; the moving block 27 can also be directly moved to the far right. Finally, after the return spring 28 is stretched to the extreme, it will drive the abutting rod 30 to slide, causing the quick-release buckle 6 to completely disengage from the card slot 7, thereby canceling the door-free suction function at a certain angle; thus, by moving the moving block 27, it is convenient for the user to freely adjust the angle of the door-free suction and the unlocking force of the door panel during door-free suction.

[0038] Moreover, the second chute 33 is arranged on the inner wall of the support shell 26, the second slider 32 is slidably connected to the second chute 33, and the second slider 32 is fixedly connected to the moving block 27. When the moving block 27 moves, the second slider 32 slides in the second chute 33 to maintain stability.

[0039] Thus, the support shell 26 has a threaded hole 37, the moving block 27 has an inclined slot 38, the second turning handle 34 is fixedly connected to one end of the second threaded rod 35, the second threaded rod 35 and the threaded hole 37 are mutually adapted, the other end of the second threaded rod 35 is fixedly connected to the second push-up inclined block 36, and the second push-up inclined block 36 and the inclined slot 38 are mutually adapted. The second turning handle 34 rotates, driving the second threaded rod 35 to rotate, and cooperates with the threaded hole 37, so that the second push-up inclined block 36 gradually moves downward, cooperates with the inclined slot 38, and drives the moving block 27 to move to the right; conversely, after the second push-up inclined block 36 is moved upward, the abutting spring 29 rebounds, and the moving block 27 can be reset to the left, so as to reduce the tension of the rebound spring 28, so that the end connected to the abutting rod 30 can be ejected a farther distance, so that the quick release buckle 6 can cooperate with the slot 7.

[0040] Furthermore, the adjustment plate 39 is rotatably connected to the intermediate housing 8, the handle 40 is arranged on the outer side of the adjustment plate 39, the limiting groove 41 is arranged on the inner side of the adjustment plate 39, the oblique clamping block 42 and the limiting groove 41 are mutually adapted, the toggle mechanism is arranged inside the intermediate housing 8, and the oblique clamping block 42 is connected to the wave mechanism. Holding the handle 40 facilitates the adjustment plate 39 to rotate, and then close the intermediate housing 8. When closing, the limiting groove 41 contacts the oblique clamping block 42, and the oblique clamping block 42 is pushed back and enters the limiting groove 41 to complete the limiting of the adjustment plate 39. When it is necessary to adjust or maintain and replace the parts inside the intermediate housing 8, the limiting of the oblique clamping block 42 is cancelled by the toggle mechanism, and the adjustment plate 39 can be opened.

[0041] Finally, the intermediate housing 8 has a slot 46, the shift block 43 is slidably connected to the slot 46, one end of the shift block 43 is fixedly connected to the oblique clamping block 42, the two ends of the telescopic rod 44 are respectively fixedly connected to the inner wall of the intermediate housing 8 and the oblique clamping block 42, the two ends of the shift block contraction spring 45 are respectively movably connected to the inner wall of the intermediate housing 8 and the oblique clamping block 42, and the telescopic rod 44 is located inside the shift block contraction spring 45. The shift block 43 is moved in the slot 46 to drive the oblique clamping block 42 to disengage from the limiting slot 41, and the telescopic rod 44 is followed by the telescopic movement to maintain stability; in addition, the shift block contraction spring 45 can drive the shift block 43 and the oblique clamping block 42 to rebound and reset, thereby allowing them to enter the limiting slot 41.

[0042] When using the hinge with an angle-adjustable door stopper according to this embodiment, it is installed on the door through the first rotating member 1 and the second rotating member 2, so as to realize the rotation function of the door. When the door drives the first rotating member 1 and the second rotating member 2 to rotate, the first rotating member 1 will drive the threaded column 4 and the connecting block 3 to rotate. The two threaded columns 4 drive the two first threaded blocks 5 to move relatively, and then drive the card slot 7 to move continuously. After moving to one side of the quick-release buckle 6, due to the action of the elastic unit, the quick-release buckle 6 enters the card slot 7, thereby realizing the limit of the door panel. At the same time, when the user continues to push the door panel, the quick-release buckle 6 can be disengaged from the card slot 7, and then the card slot 7 continues to cooperate with the quick-release buckle 6 at the next position, thereby realizing the limit of the door stopper at different angles;

[0043] Through the above structural settings, when the door panel is rotated, the first threaded block 5 can be driven to move up and down, so as to adapt to the quick-release buckles 6 at different positions in turn, and then realize the function of the door stopper for the door panel at different angles, enabling the user to freely adjust and use it, and enhancing the user experience.

[0044] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of the rights of the present application cannot be limited thereby.
