[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] Please refer to the attached Figure 1-8 The utility model provides a small-angle short-arm two-stage force hinge, which is installed between the cover plate 18 and the side plate 19, and includes a base 1 and a short arm 2. The end of the short arm 2 is rotatably connected to the upper connecting member 4 through a first pin shaft 3, and the end of the upper connecting member 4 is rotatably connected to the bag 5. A hinge cup 6 is provided on the inner side of the bag 5, and a damper 7 and a noise reduction component are fixed to the bottom of the inner wall of the hinge cup 6. The damper 7 is located on the inner side of the noise reduction component, and the side of the inner wall of the hinge cup 6 is rotatably connected to the lower connecting member 11 through a second pin shaft 10. An adjustment component for adjusting the gap between the cover plate 18 and the side plate 19 is provided between the base 1 and the short arm 2, and the lower connecting member 11 is rotatably connected to the adjustment component at one end close to the base 1, and a door resistance adjustment component is provided on the noise reduction component.

[0025] The noise reduction component includes a damper sliding kit 8, which is fixed to the bottom of the inner wall of the hinge cup 6. The damper 7 is located on the inner side of the damper sliding kit 8. A plastic protective block 9 slides on the surface of the damper sliding kit 8. The lower connecting piece 11 is close to the end of the damper 7 and is rotatably connected to the output shaft of the damper 7. Therefore, when the bag 5 and the short arm 2 rotate relative to each other, the upper connecting piece 4 and the lower connecting piece 11 can rotate. During the rotation of the lower connecting piece 11, the damper 7 is squeezed. Under the damping action of the damper 7, a buffering effect is achieved. That is, the small-angle short-arm two-stage force hinge can install one end of the damper 7 on the lower connecting piece 11, and install the other end of the damper 7 in the hinge cup of the bag 5, so that the connection distance between the base 1 and the short arm 2 to the bag 5 is short, and the hinge arm is shortened, the base is shortened, and the connection structure is simplified, achieving the technical purpose of being small, exquisite and practical, thereby meeting the needs of current exquisite personalized furniture. The surface of the second pin 10 is sleeved with a main spring 12, one end of the main spring 12 abuts against the surface of the lower connecting piece 11, and the main spring 1 2 The other end abuts against the inner wall side of the hinge cup 6, so under the elastic force of the main spring 12, it can effectively provide elastic resistance to the lower connecting piece 11 during the rotation process, and once again achieve a buffering effect, effectively preventing the cover 18 from excessively colliding with the side plate 19 when closing. The end of the plastic guard 9 abuts against the end of the lower connecting piece 11, so when the lower connecting piece 11 rotates, its end close to the pocket 5 will rotate, thereby applying an extrusion thrust to the plastic guard 9 abutting against it, so that the plastic guard 9 is in the damper sleeve sliding part. 8 slides up, from the beginning of closing the cover 18 to the process of closing the cover 18, the damper 7 and the pocket 5 buffer and close until the plastic guard block 9 hits the cup wall of the hinge cup 6, that is, hits the inner wall of the pocket 5, and the cover 18 is fully closed. Since the plastic guard block 9 is arranged in the hinge cup 6 of the pocket 5 and the plastic guard block 9 is made of plastic, the collision of the plastic guard block 9 with the lower connecting piece 11 of the metal material and the collision with the inner wall of the metal pocket 5 can effectively reduce the noise generated, and even achieve a silent effect;

[0026] The adjusting assembly includes two groups of waist-shaped holes 13, which are symmetrical and vertically opened at both side ends of the base 1, and each group of waist-shaped holes 13 has two. Connecting holes 14 are symmetrically opened at both side ends of the short arm 2, and the connecting holes 14 correspond to the waist-shaped holes 13 one by one. A first connecting shaft 15 runs through the waist-shaped holes 13 away from the lower connecting piece 11 and the corresponding connecting holes 14, and a second connecting shaft 16 runs through the waist-shaped holes 13 close to the lower connecting piece 11 and the corresponding connecting holes 14. The end of the lower connecting piece 11 close to the base 1 is rotatably connected to the base 1 through the second connecting shaft 16. The adjusting assembly also includes an adjusting screw 17, which is threadedly connected to the top of the short arm 2, and the bottom end of the adjusting screw 17 abuts against the top of the base 1. That is, the user can control the up and down movement of the adjusting screw 17 by rotating the adjusting screw 17 in the forward and reverse directions, thereby controlling the up and down adjustment of the short arm 2 relative to the base 1, so that the gap between the cover plate 18 and the side plate 19 can be easily adjusted later, which is convenient for use;

[0027] The door closing resistance adjustment assembly includes a resistance adjustment eccentric nail 20 and a nylon plastic elastic glue 21. The end of the nylon plastic elastic glue 21 close to the plastic guard block 9 is slidably connected to the top of the plastic guard block 9, and the end of the nylon plastic elastic glue 21 away from the plastic guard block 9 is in contact with the damper sliding kit 8. The bottom end of the resistance adjustment eccentric nail 20 passes through the nylon plastic elastic glue 21, and the bottom end of the resistance adjustment eccentric nail 20 is threadedly connected to the top of the plastic guard block 9. Specifically, the user can use a screwdriver to turn the resistance adjustment eccentric nail 20 clockwise to drive the nylon plastic elastic glue 21 to slide on the top of the plastic guard block 9, which can support the damper sliding kit 8, thereby preventing the damper 7 from extending out, that is, by hindering the movement of the damper sleeve sliding part 8, the purpose of indirectly hindering the extension length of the damper 7 is achieved, thereby reducing the door closing resistance. Similarly, the reverse operation increases the door closing resistance.

[0028] The usage process of the present invention is as follows: First, the damper 7 is installed in the hinge cup of the bag 5, so that the connection distance between the base 1 and the short arm 2 to the bag 5 is short, and the short arm 2 is shortened, the base 1 is shortened, and the connection structure is simplified, achieving the technical purpose of being small, exquisite and practical, thereby meeting the current needs of exquisite and personalized furniture. Secondly, the user can control the adjustment screw 17 to move up and down by rotating the adjustment screw 17 in the forward and reverse directions, thereby controlling the short arm 2 to adjust up and down relative to the base 1, so that the gap between the cover plate 18 and the side plate 19 can be adjusted conveniently later, which is convenient for use; finally, the user can use a screwdriver to turn the resistance adjustment eccentric nail 20 clockwise to drive the nylon plastic elastic glue 21 to slide on the top of the plastic guard block 9, which can support the damper sliding kit 8, thereby preventing the damper 7 from extending out, that is, by hindering the movement of the damper sleeve sliding part 8, the purpose of indirectly hindering the extension length of the damper 7 is achieved, thereby reducing the door closing resistance. Similarly, the reverse operation increases the door closing resistance.
