[0025] A torsion-adjustable hinge structure is further described below with reference to the drawings. The torsion-adjustable hinge structure comprises rotatably connected first hinge 1, second hinge 2 and rotating shaft 3. The rotating shaft comprises main shaft 31 and secondary shaft 32. The main shaft rotates with the first hinge. The secondary shaft is installed on the second hinge. The structure further comprises locking mechanism 4, which cooperates with the secondary shaft to make the secondary shaft in a rotatable state or a locked state. Operating part 35 is arranged on the outer side of the secondary shaft. When the secondary shaft is in the rotatable state, the operating part is operated to make the secondary shaft rotate relative to the main shaft. Elastic member 33 has one end connected to the main shaft and the other end connected to the secondary shaft. When the secondary shaft rotates relative to the main shaft, the elastic member is twisted and stores energy.

[0026] The elastic member can be a tension spring or rubber band, which stores energy when twisted. The stored energy increases with the rotation angle. After the secondary shaft is fixed, more force is required to rotate the secondary shaft. The elastic force also changes. The basic principle of use is that when the secondary shaft is in the rotatable state, the first hinge and the second hinge are rotated to the maximum rotatable angle. The operating part is operated by a screwdriver to make the secondary shaft rotate relative to the main shaft. Since the first hinge cannot rotate, the main shaft cannot rotate. The secondary shaft rotates relative to the main shaft. The elastic member is twisted and stores torsion. After completion, the secondary shaft is locked.

[0027] In the embodiment, as shown in the drawings, the second hinge is provided with first mounting pipe 22 and second mounting pipe 23. The locking mechanism is arranged in the first mounting pipe. The second mounting pipe is provided with damper 5. The damper provides damping force when the main shaft rotates. The damper provides damping when the hinge rotates, buffers the elastic force and makes the mechanism run more smoothly.

[0028] In the embodiment, the locking mechanism comprises a sleeve 41, a ball 42 and a sleeve 44, the sleeve is arranged on the outer wall of the secondary shaft and fixedly arranged on the first mounting pipe, the sleeve is arranged between the outer wall of the sleeve and the inner wall of the first mounting pipe, the ball is arranged on the outer wall of the secondary shaft, the sleeve is provided with a through hole for the ball to pass through, the sleeve is in sliding fit with the sleeve, the inner wall of the sleeve is provided with a first groove 421 for pressing the ball to be non-rotatable and a second groove 422 separated from the ball. When the first groove of the sleeve is matched with the ball, the ball is pressed and non-rotatable, and since the sleeve is fixed, the secondary shaft is also non-rotatable. When the second groove of the sleeve is matched with the ball, the ball can be rotated at will, and at this time, the secondary shaft is in a state of adjustable torsion. The ball can be arranged on the secondary shaft or in a ball socket.

[0029] In the embodiment, the locking mechanism further comprises a lever 43 and an L-shaped groove 47 arranged through the outer wall of the first mounting pipe, the lever is connected with the sleeve and drives the sleeve to slide by operating the lever, and part of the lever extends out of the first mounting pipe through the L-shaped groove. One end of the L-shaped groove is opposite to the first groove, and the other end of the L-shaped groove is opposite to the second groove.

[0030] In the embodiment, the outer wall of the sleeve is further sleeved with a compression spring 315, the compression spring is used to apply force to arrange the ball in the first groove. The compression force is guaranteed to prevent slipping.

[0031] In the embodiment, the primary shaft is a tubular structure, one end of the primary shaft is provided with a first hook 311, the secondary shaft is provided with a second hook 312, one end of the elastic member is connected with the first hook, the other end of the elastic member is connected with the second hook, and at least part of the elastic member is arranged in the inner cavity of the primary shaft.

By adjusting the installation height of the bottom cover, the size of the damping force can be adjusted. If the installation is lower, some oil will run into 530, reducing the contact amount of the damping oil and the support plate.
