[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution for a charging cable and connector for lamps: a charging cable for lamps, including a cable body 2, the cable body 2 is connected to the lamp 1, one end of the cable body 2 is fixedly connected to a charging plug 5, and the other end is fixedly connected to a connector 3, and a connection port matching the connector 3 is fixedly connected to the lamp 1, a box body 4 is sleeved on the outside of the cable body 2, the box body 4 is a closed setting, and openings are opened on both sides of the box body 4, and the cable body 2 passes through the inside of the box body 4 and the two openings in sequence.

[0022] According to the overall structure of the device, a connector is formed by the cable body 2, the charging plug 5 and the connector 3 to realize the connection between the lamp 1 and the power supply. When in use, the charging cable can be quickly connected to the lamp 1 by plugging the connector 3 on the cable body 2 into the pre-equipped connection port on the lamp 1. It can also be unplugged at any time, which is convenient for replacing the charging cable when it is damaged. The charging cable can be stored in the box body 4, so that the length of the charging cable can be adjusted according to usage requirements, which is convenient for the use of the lamp 1.

[0023] like Figure 2 、 3 As shown, a movable rod 9 is movably connected in the box body 4, and a through slot is opened on the movable rod 9. The cable body 2 passes through the through slot and is wound around the movable rod 9 from the middle to both ends.

[0024] The charging cable in the box body 4 is wound and stored by the movable rod 9, so that the charging cable is neatly stored in the box body 4 and the charging cable is prevented from being entangled.

[0025] like Figure 2 As shown, a cylindrical fixing block 10 is fixedly connected to the middle of the movable rod 9 , a spiral spring 6 is fixedly connected to the outside of the fixing block 10 , and the spiral spring 6 is fixedly connected to the box body 4 .

[0026] The charging cable is retracted into the box body 4 through the spiral spring 6. When the charging cable is pulled out, the movable rod 9 is driven to rotate, thereby compressing the spiral spring 6. When the charging cable is retracted, the spiral spring 6 is released, driving the movable rod 9 to rotate in the opposite direction, thereby retracting the charging cable into the box body 4.

[0027] like Figure 4As shown, an annular groove is provided on the outside of the fixed block 10, and the spiral spring 6 is located in the annular groove. Several tooth blocks are fixedly connected to the side walls of the fixed block 10 near the left and right edges, and the several tooth blocks are distributed in an annular array along the side walls of the fixed block 10. A movable block 7 is provided in the box body 4, and a tooth groove matching the tooth block is provided on the movable block 7. A threaded hole is provided on the front side of the box body 4, and a screw 8 is threadedly connected to the threaded hole, and one end of the screw 8 is fixedly connected to a knob, and the other end is movably connected to the movable block 7. The inner wall of the box body 4 is fixedly connected to a limit plate, and a limit groove matching the limit plate is provided on the movable block 7.

[0028] The screw rod 8 is turned by turning the knob to move the screw rod 8 relative to the box body 4 and drive the movable block 7 to move. The movable block 7 moves inward, and the tooth groove engages with the tooth block to fix the fixed block 10 and the movable rod 9, thereby fixing the length of the charging cable and preventing the charging cable from being retracted into the box body 4 or released from the box body 4. The movable block 7 moves outward, and the tooth block is separated from the tooth groove. At this time, the movable rod 9 is in a relaxed state. Pulling the two ends of the cable body 2 can pull out the inner part of the box body 4 for extension, or drive the movable rod 9 to rotate the cable body 2 to reel in the charging cable and shorten the charging cable. The movable block 7 is limited by the limit plate and the limit groove to prevent the movable block 7 from deflecting. A slot is provided in the middle of the movable block 7 relative to the fixed block 10 to avoid direct contact between the spiral spring 6 and the movable block 7, thereby facilitating the release of the spiral spring 6.

[0029] Working principle: When in use, a connection port is pre-installed on the lamp 1. By plugging the connector 3 on the cable body 2 into the connection port pre-equipped on the lamp 1, the charging cable can be quickly connected to the lamp 1, and it is convenient to replace the charging cable when it is damaged. The charging cable can be stored through the box body 4. Turn the screw 8 to move the movable block 7 away from the fixed block 10, and the tooth groove is separated from the tooth block. At this time, the cable body 2 can be pulled outward from the left and right sides of the box body 4 to extend the charging cable. At the same time, the spiral spring 6 is compressed and the cable body 2 is loosened. The spiral spring 6 is released to drive the movable rod 9 to reverse and retract the cable body 2 into the box body 4, so that the length of the charging cable can be adjusted according to usage requirements, which is convenient for the use of the lamp 1.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
