DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0014] The USB power cord structure for the air pump has a storage and winding structure, which can effectively adjust the use of the USB power cord so that the length of the USB power cord can be adjusted according to usage requirements, thereby effectively avoiding the problem of USB power cord entanglement and effectively protecting the power cord.

[0015] Depend on Figures 1 to 3 The utility model comprises a USB power cord body 1 and a storage block 2. The surface of the USB power cord body 1 is provided with a woven mesh layer, so that the USB power cord body 1 can be safely and effectively pulled out. An arc groove 17 is opened at one corner of the storage block 2, and a connecting ring 18 is installed inside the arc groove 17, so that it can be effectively held and carried.

[0016] A storage circular groove 3 is opened in the middle of the storage block 2, and a rotating shaft 4 is rotatably connected to the middle of the storage circular groove 3. A rubber sleeve 5 perpendicular to the rotating shaft 4 is fixedly installed in the middle of the rotating shaft 4. The USB power cord body 1 symmetrically passes through the rubber sleeve 5 and is connected to the rubber sleeve 5 by adhesive. One end of the rotating shaft 4 extends to the surface of the storage block 2 and is fixedly connected to a rotating cover 6. The surface of the rotating cover 6 is provided with raised blocks for increasing friction at equal distances in a ring.

[0017] Both sides of the storage block 2 are provided with connector storage grooves 7, and through grooves 8 are provided between the two connector storage grooves 7 and the storage circular groove 3. The USB power line body 1 passes through the connector storage grooves 7 and the through grooves 8. Both sides of the storage block 2 are provided with rubber card covers 9 for sealing the connector storage grooves 7. One end of the rubber card cover 9 is connected to the storage block 2 through a rubber strip 10. The connectors at both ends of the USB power line body 1 can be effectively stored by the arrangement of the connector storage grooves 7, and the connector storage grooves 7 can be effectively sealed and stably and effectively stored by the arrangement of the rubber card cover 9. A fixing ring 11 is fixedly installed on the surface of the storage block 2, and the rotating The shaft 4 passes through the fixed ring 11, and the surface of the rotating shaft 4 is provided with V-shaped grooves 12 at equal intervals in an annular manner. Two fixed tubes 13 are symmetrically fixedly connected to the inner arc surface of the rotating cover 6. One end of the two fixed tubes 13 is movably plugged with an inverted T-shaped pin 14, and one end of the inverted T-shaped pin 14 is fixedly connected with a triangular block 15 movably plugged with the inside of the V-shaped groove 12. A spring 16 is sleeved between the surfaces of the fixed tube 13 and the inverted T-shaped pin 14, and the two ends of the spring 16 are respectively fixedly connected to the inverted T-shaped pin 14 and the inner arc surface of the rotating cover 6, so that the rotating cover 6 can be effectively rotated to adjust the rotating shaft 4, and the USB power cable body 1 can be stably and effectively adjusted to be retracted and released;
