DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples. Figures 1 to 3 Read.

[0018] Example 1:

[0019] refer to Figures 1 to 3 As shown,

[0020] Provided is a hinge, comprising: a first hinge 1, a second hinge 2, a first sleeve 11, and a second sleeve 21, wherein the first hinge 1 is fixedly connected to the first sleeve 11, the second hinge 2 is fixedly connected to the second sleeve 21, a portion of the first sleeve 11 is inserted into the second sleeve 21, and an internal space formed after the first sleeve 11 is inserted into the second sleeve 21 is provided with an upper cover 3, a spring 4, a drive shaft 5, a transverse shaft 6, a cylinder rod 7, a buffer mechanism 8, and a lower cover 9 from top to bottom, the upper portion of the drive shaft 5 extends into the first sleeve 11, and the upper portion of the drive shaft 5 forms the same space as the first sleeve 11. The drive shaft 5 is connected by step rotation and axial sliding. The lower part of the drive shaft 5 is a hollow tube. The lower part of the drive shaft 5 is axially symmetrically provided with a spiral groove 51. The connection between the upper part of the drive shaft 5 and the lower part of the drive shaft 5 is provided with a step surface 52. The second sleeve 21 is axially symmetrically provided with an embedding portion 212. The transverse shaft 6 passes through the spiral groove 51. The two ends of the transverse shaft 6 are inserted into the embedding portion 212. The lower end of the first sleeve 11 abuts on the step surface 52 of the drive shaft 5. The upper part of the cylinder rod 7 abuts on the lower end of the drive shaft 5. The lower part of the cylinder rod 7 is connected to the buffer mechanism 8.

[0021] Through the above technical solution, when the user opens or closes the door, the hinge tube rotates, and this rotation is converted into the axial up and down movement of the drive shaft. One of the two end faces of the drive shaft abuts against the end face of the pressure spring, and the other end face abuts against the end face of the telescopic part of the buffer mechanism. The drive shaft can receive the stored energy and released energy of the pressure spring without the need for other excessive connection transmissions. The buffer mechanism, such as the buffer cylinder, is also directly driven by the drive shaft, reducing other connecting components, achieving cost savings, and facilitating production.

[0022] Furthermore, the upper cover 3 can be adjusted up and down in the first sleeve 11. This can control the up and down position of the spring and thus control the pressure value of the spring and the power of opening and closing the door.

[0023] Furthermore, the upper cover 3 can be adjusted vertically within the first sleeve 11 by: a first internal thread 111 is provided on the inner wall of the first sleeve 11, and upper cover teeth 31 are provided on the side outer wall of the upper cover 3. By rotating the upper cover teeth 31 within the first internal thread 111, the upper cover 3 can be rotated and adjusted vertically within the first sleeve 11. The structure for vertical adjustment is formed by the combination of the thread and the teeth, and the parts are easy to manufacture.

[0024] Furthermore, the lower cover 9 can be adjusted up and down in the second sleeve 21. This makes it possible to control the up and down position of the buffer mechanism, thereby controlling the buffer speed of opening and closing the door.

[0025] Furthermore, the lower cover 9 can be adjusted vertically within the second sleeve 21 by: a second internal thread 211 is provided on the inner wall of the second sleeve 21, and lower cover teeth 91 are provided on the side outer wall of the lower cover 9. By rotating the lower cover teeth 91 within the second internal thread 211, the lower cover 9 can be rotated vertically within the second sleeve 21 to adjust its position. The use of the thread and teeth to form a structure for vertical adjustment simplifies the processing of the parts.

[0026] Furthermore, the upper portion of the drive shaft 5 and the first sleeve 11 form a synchronous rotation and axial sliding connection in a specific manner: the inner wall of the lower portion of the first sleeve 11 is provided with a spline groove 112, and the upper portion of the drive shaft 5 is a spline shaft 53. The drive shaft 5 and the first sleeve 11 form a synchronous rotation and axial sliding connection through the spline shaft 53 and the spline groove 112. The structure of the synchronous rotation and axial sliding connection formed by the spline shaft and the spline groove simplifies the processing of the parts.

[0027] Furthermore, the specific way in which the cylinder rod 7 abuts against the lower end of the drive shaft 5 is as follows: an end cap 54 is provided on the lower end surface of the lower portion of the drive shaft 5, and the cylinder rod 7 abuts against the end cap 54. The end cap abuts against the cylinder rod, increasing the contact surface and making the transmission more stable.
