[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 of 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.

[0028] Please refer to Figure 1 - Figure 7 As shown, the present utility model is a portable USB charger, including a charging housing 1. One end of the charging housing 1 is provided with a cover body 2. One end of the cover body 2 is rotatably connected with a power connection plug 3. The other end of the cover body 2 is provided with a copper sheet 4. The charging housing 1 includes an upper housing 101 and a lower housing 102. The upper housing 101 is hinged to the lower housing 102 through a hinge 5. The upper housing 101 and the lower housing 102 cooperate to form a chamber. A circuit board 6 is installed inside the chamber. One end of the circuit board 6 is provided with a first USB socket 601, a second USB socket 602 and a signal lamp 603. Fixing components 7 are arranged on the outer surfaces of both the upper housing 101 and the lower housing 102;

[0029] The outer surface of the cover body 2 is provided with a groove, and an electric connection plug 3 is arranged inside the groove. Through holes corresponding to the first USB socket 601, the second USB socket 602 and the signal lamp 603 are provided on the outer surface of the lower housing 102;

[0030] When the charger is in use, by rotating the electric connection plug 3, the electric connection plug 3 rotates 90° along the axis in the groove, so that the electric connection plug 3 disengages from the groove. During the rotation process of the electric connection plug 3, the contacts of the electric connection plug 3 will gradually abut against the outer surface of the copper sheet 4 to realize the connection of the circuit. After inserting the connector of the data cable into the matching USB socket, insert the electric connection plug 3 into the socket. The current passes through the electric connection plug 3 and the copper sheet 4 in sequence and supplies power to the circuit board 6, so that the current of the circuit board 6 flows through the USB socket into the inside of the data cable and charges the mobile phone through the data cable;

[0031] The fixing component 7 includes a mounting block 701. An installation groove 702 is provided on the upper surface of the mounting block 701. A slot is provided on the outer surface of the mounting block 701. A baffle 703 is fitted and installed inside the installation groove 702. A chute 704 is provided on the outer surface of the baffle 703. A guide rod 705 is provided on the inner surface of the installation groove 702. A sliding member 706 is slidably connected to the outer surface of the guide rod 705;

[0032] The sliding member 706 includes a sliding plate 70601. Sliders 70602 are provided at both ends of the sliding plate 70601. The sliders 70602 are slidably connected to the outer surface of the guide rod 705. A connecting block 70603 is provided on the upper surface of the sliding plate 70601. The connecting block 70603 is slidably connected to the inside of the chute 704. A dial block 70604 is provided on the upper surface of the connecting block 70603;

[0033] A spring 707 is sleeved on the outer surface of the guide rod 705. One end of the spring 707 is installed on the inner surface of the installation groove 702, and the other end of the spring 707 is installed on the outer surface of the slider 70602;

[0034] A limiting block 8 is installed on the outer surface of the sliding plate 70601. One end of the limiting block 8 penetrates through the mounting block 701 and extends outward;

[0035] The two mounting blocks 701 are symmetrically arranged. The socket provided on the outer surface of one mounting block 701 and the limiting block 8 provided on the outer surface of the other mounting block 701 are located on the same horizontal line, and the limiting block 8 is fitted and installed inside the slot;

[0036] When the electronic components inside the charging housing 1 need to be replaced, the two sliding members 706 are pushed outward so that the sliding members 706 slide axially outward in the mounting groove 702, so that the two limit blocks 8 gradually disengage from the corresponding slots, and the spring 707 gradually contracts. When the two limit blocks 8 are flush with the outer surfaces of the corresponding mounting blocks 701, the upper housing 101 and the lower housing 102 can be moved outward so that one end of the upper housing 101 and the lower housing 102 rotates axially along the axis with the hinge 5 as the center, thereby realizing the separation of the upper housing 101 and the lower housing 102, exposing the electronic components in the chamber, and then the damaged electronic components can be replaced;

[0037] The outer surfaces of the charging housing 1 , the cover 2 and the fixing assembly 7 are all coated with a wear-resistant coating.

[0038] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model.
