[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-6 A portable power bank with a convenient rotating interface, comprising: The power supply body 1 has a connecting groove 4 on one side shaft end and a countersunk hole 8 on the side wall of the power supply body 1, which communicates with the interior of the connecting groove 4. A rotary joint assembly is disposed inside the connecting groove 4, with its two opposite sides corresponding to the inner wall of the connecting groove 4 for rotatable engagement. The clamping component is located inside the countersunk hole 8. The clamping component is engaged with the rotary joint component to achieve rotational fixation of the rotary joint component.
[0016] Furthermore, two symmetrically distributed mating grooves 5 are provided on the two opposite inner walls of the connecting groove 4, and a rotating groove 6 is provided on the inner side wall of the connecting groove 4. The side wall of the rotating groove 6 is perpendicular to the side wall of the mating groove 5. A sliding groove 7 is provided on the top of the rotating groove 6. The sliding groove 7 is perpendicular to the rotating groove 6 and communicates with the countersunk hole 8. The rotating groove 6 can play multiple roles of connection, limiting and fixing, ensuring the reliable connection of the rotating interface head 2.
[0017] Furthermore, the rotary joint assembly includes a rotary interface head 2 and a torsion spring 12. The main body of the rotary joint assembly is the rotary interface head 2, and two torsion springs 12 are provided inside the two opposite side walls of the rotary interface head 2 in an axisymmetrically distributed manner.
[0018] Furthermore, the rotating interface head 2 has an interface 9 on its side wall, and a limiting block 10 is provided on the side of the rotating interface head 2 away from the interface 9. The interface 9 and the limiting block 10 are symmetrically distributed. Two mounting holes 13 are provided on the two opposite side walls of the rotating interface head 2 in an axially symmetrical distribution. A mating block 11 is provided inside the mounting hole 13. The mating block 11 is rotatably connected to the mating groove 5.
[0019] Furthermore, the torsion spring 12 is correspondingly sleeved on the outside of the mating block 11, and the two shaft ends of the torsion spring 12 are correspondingly engaged in the mounting hole 13 and the mating groove 5. The torsion spring 12 is always in a state of rotational compression, providing effective power for the rotation of the rotating interface head 2 and its internal fixation, ensuring that the rotation and fixation are carried out smoothly.
[0020] Furthermore, the clamping assembly includes a rotary button 3 and a spring 14. The rotary button 3 has a slider 15 inside the corresponding connecting groove 4. The slider 15 is slidably connected to the inside of the sliding groove 7. A connecting rod 16 is welded to one side of the shaft end of the slider 15. A button block 17 is provided on the side of the connecting rod 16 away from the slider 15. The button block 17 is slidably connected to the countersunk hole 8. The rotary button 3 controls the fixing status of the rotating interface head 2 inside the power supply body 1 by whether it cooperates with the limiting block 10. When the rectangular opening 18 coincides with the rotating groove 6, that is, the limiting block 10 of the rotating interface head 2 rotates under the rebound action of the torsion spring 12, that is, the interface 9 rotates out. Or the limiting block 10 enters the top of the rotating groove 6 and is clamped by the slider 15, thus completing the internal fixing.
[0021] Furthermore, the spring component 14 consists of two axially symmetrically distributed mating plates 20 and a spring 19. The spring 19 is welded between the two springs 19. The mating plates 20 have a circular hole along their center that engages with the connecting rod 16. The spring 19 is always in a compressed state, providing internal force to the inside of the slider 13, ensuring that the fixation of the limiting block 10 is always effective.
[0022] Working principle: Install the portable power bank with the convenient rotating interface correctly as shown in the diagram. When the power bank is fully charged and ready for charging, press the rotating button 3, which consists of a slider 13 and a spring 14. This causes the slider 13 to slide into the power bank body 1, compressing the spring 14. At this time, the rotating interface head 2, under the rebound action of the torsion springs 12 on both sides, rotates around the axis of the mating block 11 inside the connecting groove 4 of the power bank body 1. Simultaneously, the limiting block 10 of the rotating interface head 2 disengages from the rectangular opening 18 of the slider 13 and rotates out onto the rotating groove 6 inside the connecting groove 4. Release the slider 13, and the slider 13 will return to its original position under the rebound action of the spring 14. At this time, rotate the interface 9 of the interface head 2 to connect for charging. After charging is completed, the interface 9 needs to be retracted. Press the rotation button 3 so that the rectangular opening 18 of the slider 13 is aligned with the rotation groove 6. Rotate the interface head 2 by hand so that the limiting block 10 of the rotating interface head 2 is pressed through the rectangular opening 18 to the top of the rotation groove 6. Release the slider 13, and the spring 14 will rebound again, the rectangular opening 18 will be misaligned with the rotation groove 6, and the limiting block 10 will be locked at the top of the rotation groove 6, thus completing the retraction of the interface 9.
