[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example:

[0029] Reference Figure 1-5 , an adjustable self-resetting hinge, comprising a cup iron head 1, a straight main body 2, the cup iron head 1 is rotatably connected to the straight main body 2, and also comprises: a piston rod column 602, which is rotatably connected in the straight main body 2; a piston rod core 601, which is slidably connected in the piston rod column 602, and one end of the piston rod core 601 is rotatably connected to the cup iron head 1; a spring member 603, which is connected in the piston rod column 602, and the spring member 603 is used for resetting the piston rod core 601; an opening 8, which is respectively arranged on the straight main body 2 and the piston rod column 602; a mounting block 701, which is fixedly connected to the straight main body 2, and a groove is arranged in the mounting block 701; a connecting rod 702, which is slidably connected in the opening 8, and one end of the connecting rod 702 is rotatably connected to the spring member 603; The spring member 603 is connected; the screw rod 703 is threadedly connected to the connecting rod 702, one end of the screw rod 703 is slidably connected in the groove, the screw rod 703 is used to adjust the position of the connecting rod 702 in the hollow 8, the end of the connecting rod 702 away from the screw rod 703 is fixedly connected with a slider 604, the slider 604 is slidably connected in the piston rod column 602, a torsion spring 3 is arranged in the cup iron head 1 and the straight bar main body 2, the two ends of the torsion spring 3 are respectively connected to the cup iron head 1 and the straight bar main body 2, a connecting head 4 is rotatably connected in the straight bar main body 2, the other end of the connecting head 4 is rotatably connected to the cup iron head 1, a right-angle bar 5 is rotatably connected in the straight bar main body 2, and the two ends of the right-angle bar 5 are respectively rotatably connected to the cup iron head 1 and the piston rod core 601.

[0030] When the device is in use, the straight bar main body 2 is installed on the door, and the cup iron head 1 is installed on the door frame. Then, when in use, the straight bar main body 2 can be rotated on the cup iron head 1 by rotating the door. At this time, the torsion spring 3 is in a compressed state. Then, as the door rotates, the connecting head 4 will rotate accordingly, and then the right-angle bar 5 can be driven to rotate. At this time, the rotation of the right-angle bar 5 will cause the piston rod core 601 to move from the piston rod column 602, thereby causing the piston rod core 601 to continuously move away from the slider 604, so that the spring member 603 is stretched. During this process, the piston rod column 602 will have a certain rotation amplitude. At this time, the screw rod 703 will slide slightly in the groove, and the slider 604 will play a similar damping effect to reduce the sound generated by the subsequent reset. When the door loses its driving force, it will reset. At this time, under the joint action of the torsion spring 3 and the spring member 603, the connecting head 4 and the right-angle bar 5 will reset, thereby resetting the door.

[0031] During daily use, the screw rod 703 can be rotated with a small wrench to move the connecting rod 702 in the opening 8. At this time, the movement of the connecting rod 702 will drive the slider 604 to move, thereby gradually stretching the length of the spring member 603. As the spring member 603 is gradually stretched, the stretched length of the spring member 603 will increase relatively during subsequent use, and the force generated by the reset will become larger. In this way, the speed of opening and closing the door can be continuously adjusted until the appropriate position is reached. The spring member 603 needs to have good performance, and the pulling range cannot exceed the elastic limit to avoid long-term stretching that causes the inability to reset.

[0032] The utility model adjusts the length of the spring member 603 through the position-adjustable connecting rod 702. As the spring member 603 is stretched, the time required for resetting can be gradually shortened, which is convenient for use in different situations.

[0033] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
