[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] The present utility model provides a Figure 1 - Figure 2 double-axis inclined wedge spiral groove synchronous rotating shaft hinge as shown, including an outer shell appearance part 1, an upper connecting sheet metal part 11, and a lower connecting sheet metal part 10. The upper connecting sheet metal part 11 and the lower connecting sheet metal part 10 are both movably arranged on the outer shell appearance part 1. An inner end face cover plate 8 is arranged between the upper connecting sheet metal part 11, the lower connecting sheet metal part 10 and the outer shell appearance part 1. Inclined wedge spiral groove parts 7 are symmetrically arranged on the inner end face cover plate 8. A connecting structure is arranged between the inclined wedge spiral groove parts 7 and the inner end face cover plate 8. The connecting structure includes an upper shaft part 5, a lower shaft part 13 and two pins 6. The upper shaft part 5 is fixedly arranged with the upper connecting sheet metal part 11, the lower shaft part 13 is fixedly arranged with the lower connecting sheet metal part 10, and the two pins 6 are respectively movably arranged in the two inclined wedge spiral groove parts 7.

[0018] Specifically refer to Figure 1 and Figure 2, through slots are symmetrically formed in the inner end face cover plate 8. The formation of the two through slots facilitates the insertion connection of the upper shaft member 5 and the lower shaft member 13 with the inner end face cover plate 8 respectively. The inclined wedge spiral groove part 7 is in communication with the inner cavity of the through slot, so as to enable the pin 6 installed on the upper shaft member 5 to rotate along the inclined wedge spiral groove part 7. Similarly, for the pin 6 on the lower shaft member 13. The upper connecting sheet metal part 11 and the lower connecting sheet metal part 10 are respectively connected to the keyboard host end and the display screen end of the portable B-ultrasound machine during use. The upper connecting sheet metal part 11 and the lower connecting sheet metal part 10 are respectively fixed to the upper shaft member 5 and the lower shaft member 13. When the upper connecting sheet metal part 11 rotates, it will drive the upper shaft member 5 to rotate. When the upper shaft member 5 rotates, it will drive the pin 6 to rotate along the inclined wedge spiral groove part 7. When one of the inclined wedge spiral groove parts 7 rotates, it will drive the lower shaft member 13 to rotate synchronously. The rotation of the lower shaft member 13 will drive the lower connecting sheet metal part 10 to rotate synchronously. Thus, the rotation of the double shafts can be synchronized. And during installation and use, the housing exterior part 1 is outside the connecting device and not within the connecting range. The setting of this double shaft can rotate 360°, increasing the rotation range of the connecting device and effectively improving the rotation flexibility and applicability.

[0019] Rivets 9 are provided on both the upper shaft member 5 and the lower shaft member 13. The rivets 9 are used for fixing the upper connecting sheet metal part 11 and the upper shaft member 5. Self-locking mechanisms 4 and elastic mechanisms 3 are provided on the end faces of the upper shaft member 5 and the lower shaft member 13 facing away from the upper connecting sheet metal part 11. The elastic mechanism 3 is fixedly arranged on the self-locking mechanism 4.

[0020] Specific reference Figure 1 and Figure 2 , the self-locking mechanism 4 is movably arranged with both the upper shaft member 5 and the lower shaft member 13. One end of the rivet 9 penetrates through the upper shaft member 5 and is fixed to the upper connecting sheet metal part 11. Through the setting of the rivet 9, the connection stability between the upper shaft member 5 and the upper connecting sheet metal part 11 is strengthened. The self-locking mechanism 4 internally has a convex and concave cam structure. A certain pressure is pre-applied to the bowl-shaped elastic piece in the elastic mechanism 3. When the cam boss inside the self-locking mechanism 4 enters the concave groove of the concave cam, the elastic mechanism 3 releases elastic force to achieve the automatic closing function.

[0021] A cover plate fixing screw 12 is arranged in the middle of the inner end face cover plate 8. The cover plate fixing screw 12 is used for fixing the inner end face cover plate 8 in the housing exterior part 1. An outer end face cover plate 2 is fixedly arranged at the end of the cover plate fixing screw 12 facing away from the inner end face cover plate 8. The outer end face cover plate 2 is fixedly arranged with the housing exterior part 1.

[0022] Furthermore, the outer end face cover plate 2 is fixedly arranged with the self-locking mechanism 4. The outer end face cover plate 2 provides stable support for the self-locking mechanism 4 and other structures through its fixed arrangement with the outer shell appearance part 1. The cover plate fixing screw 12 is used for fixing the outer end face cover plate 2 and the inner end face cover plate 8 to the outer shell appearance part 1, and the outer end face cover plate 2 is fixedly arranged with the self-locking mechanism 4. During actual use, the outer end face cover plate 2 and the inner end face cover plate 8 are fixedly installed in the outer shell appearance part 1.
