[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0018] like Figures 1 to 6As shown, a combined safety charger includes a charger body 1, a power cord 2 and a charging cord 3, the left and right sides of the charger body 1 are provided with mounting wire holes 4, one end of the power cord 2 and the charging cord 3 are provided with a detachable connector 5, and the other end of the power cord 2 is provided with a power connector 6, and the other end of the charging cord 3 is provided with a charging connector 7, a spring seat 8 is provided on the detachable connector 5, and a locking collar 9 is slidably connected to the detachable connector 5, the locking collar 9 is connected to the spring seat 8 through a compression spring, and a sleeve 10 is rotatably connected to the locking collar 9, and after the detachable connector 5 is plugged into the mounting wire hole 4, the sleeve 10 can be threadedly connected to the mounting wire hole 4.

[0019] The working principle of the combined safety charger described in the utility model is realized by the cooperation between the charger body 1, the power wire 2 and the charging wire 3. Figures 1 to 6 As shown, the power wire 2 and the charging wire 3 are connected to the charger body 1 through the detachable connector 5 respectively. When the detachable connector 5 is plugged into the installation wire hole 4, the sleeve 10 abuts against the charger body 1 and drives the locking collar 9 to compress the compression spring. In this way, the sleeve 10 always surrounds the detachable connector 5 to prevent the user's hand from accidentally touching the detachable connector 5, thereby playing a protective role. After the detachable connector 5 is plugged into the installation wire hole 4 of the charger body 1, the user can rotate the sleeve 10 on the detachable connector 5 and make the sleeve 10 threadedly connected to the installation wire hole 4, and the sleeve 10 extends. The sleeve 10 is inserted into the installation wire hole 4 to reset the compression spring, thereby completing the installation of the detachable connector 5 and the charging body. Similarly, rotating the sleeve 10 in the opposite direction can separate the sleeve 10 from the installation wire hole 4, so as to pull the detachable connector 5 out of the installation wire hole 4. Compared with the traditional charger, after the detachable connector 5 is plugged into the installation wire hole 4, the sleeve 10 of the combined safety charger can be threadedly connected to the installation wire hole 4, and after the sleeve 10 is connected to the installation wire hole 4, the detachable connector 5 can be positioned to prevent the detachable connector 5 from being loosened by being pulled by foreign objects, thereby affecting the charging safety of the charger body 1.

[0020] Specifically, a plug hole 11 is provided in the middle of the mounting wire hole 4, the spring seat 8 is provided on the side of the detachable joint 5 facing the power wire 2 or the charging wire 3, and a plug 12 is provided on the other side of the detachable joint 5 away from the spring seat 8, wherein a plurality of slide grooves 13 are evenly provided on the circumference of the detachable joint 5, and the two ends of the compression spring are connected to the opposite sides of the locking collar 9 and the spring seat 8, and a plurality of sliders 14 are evenly provided on the inner circumference of the locking collar 9, and the plurality of sliders 14 are correspondingly slidably connected with the slide grooves 13, such as Figures 1 to 6As shown, when the compression spring is not compressed, the sleeve 10 can surround and block the plug 12. When the plug 12 of the detachable connector 5 is inserted into the socket 11 of the mounting wire hole 4, the sleeve 10 abuts against the charger body 1 and drives the locking collar 9 to compress the compression spring. The locking collar 9 moves toward the spring seat 8 along the slide groove 13 of the detachable connector 5 through the slider 14, so that the sleeve 10 always surrounds the plug 12 to prevent the user's hand from accidentally touching the detachable connector 5.

[0021] Further, the inner side of the mounting wire hole 4 is provided with internal threads around, the sleeve 10 is rotatably connected with the locking collar 9 toward the side of the plug 12, the outer side of the sleeve 10 is provided with external threads, and the sleeve 10 is threadedly connected with the internal threads of the mounting wire hole 4 through the external threads, and further, the slide groove 13 is extended from the spring seat 8 toward the plug 12, and the length of the slide groove 13 is the same as the hole depth of the mounting wire hole 4, such as Figures 1 to 6 As shown, a bearing can be provided on one side of the locking collar 9 to be rotatably connected with the sleeve 10. After the plug 12 of the detachable connector 5 is plugged into the socket 11 of the mounting wire hole 4, the user rotates the sleeve 10 to make the external thread of the sleeve 10 threadably connected with the internal thread of the mounting wire hole 4, and the sleeve 10 gradually extends into the mounting wire hole 4 and gradually resets the compression spring until the sleeve 10 abuts against the bottom of the mounting wire hole 4. At this time, the slider 14 of the locking collar 9 abuts against the side of the slide groove 13 away from the spring seat 8. In this way, if the detachable connector 5 is pulled by an external object, the slider 14 of the locking collar 9 cooperates with the slide groove 13 to limit the outward movement of the detachable connector 5 and avoid looseness between the detachable connector 5 and the charger body 1 to affect the charging safety of the charger body 1.

[0022] The above are only specific embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
