A USB port with a USB connector that communicates with the USB socket assembly.

 In this scenario, the elastic USB The connecting piece can be separated from the base or the lamp cap, or the lamp cap can be directly inserted into the base for use, and the use is very flexible, and at the same time, since the three are detachable, the carrying is greatly facilitated. In addition, by utilizing the plasticity and bendability of the elastic connecting piece, as the supporting core of the lamp connecting piece, when the need to support the lamp cap, the elasticity will be The USB connector is straightened, and the elastic connecting piece is straightened and has a certain load-bearing capacity enough to support the weight of the lamp cap. Resilient USB when needed for storage When the connecting member is bent, the elastic connecting piece can be bent and wound into a circle, which greatly saves the storage space.

 Further, the elastic connecting piece is an elastic steel piece, and the USB socket component is directly connected to the USB plug component through the elastic steel piece, or The USB socket assembly is electrically connected to the USB plug assembly via conductive elements.

 The base comprises a housing and a control circuit disposed in the housing, and a rechargeable battery connected to the control circuit, wherein the housing is provided with a USB connected to the control circuit Port. The USB port provides emergency power and can be used as a mobile power source to charge USB mobile devices such as mobile phones, tablets, and MP3s.

 The control circuit can control the flashing of the lamp head SOS International rescue signal. As a portable desk lamp, it is often used in the wild, and when it is dangerous or difficult in the field, because the communication signal in the field is poor, it is especially important that the portable desk lamp can send a distress signal.

 The USB The port is located on the rear side of the upper surface of the housing, and its direction is set toward the front of the slanting front. This design ensures the overall balance of the desk lamp and avoids the situation of top-heavy. In addition to the USB The port can also be rotatably connected to the housing to flexibly adjust the connection position of the flexible USB connector to accommodate different light exit angles.

 The side of the housing is provided for accommodating elastic USB The groove structure of the connecting member and the recess structure for accommodating the first and second receiving chambers. A fixing bracket is further disposed on the back surface of the housing, and is rotatably connected to the housing through the pin structure. The outer end of the pin structure is rotatably coupled to the fixing bracket, and the inner end of the pin structure is connectable with a pin hole provided on the lamp cap.

 The fixing bracket is provided with a strip-shaped opening for the elastic USB connecting member to pass through, and one side of the strip-shaped opening is provided for the elastic USB The opening into which the connector is loaded.

 The first and second receiving cavities are larger in size than the strip-shaped opening, and the sheath is smaller in size than the strip-shaped opening, and the elastic USB The hook structure can be formed after the connecting member is fitted into the strip opening.

 The lamp cap comprises a casing, an LED lamp panel, a diffuser panel and the USB connector, LED The light board is disposed in the outer casing, the diffuser board is disposed at the light exit of the outer casing, the outer casing is rotatably connected to the USB connector, and the USB connector is electrically connected to the LED light board.

A rib structure is arranged between the sheath and the elastic connecting piece, and the rib structure is evenly disposed between the sheath and the elastic connecting piece, and the gap between the sheath and the elastic connecting piece is kept uniform. Since the bending or straightening of the elastic connecting piece causes the sheath to be deformed at the same time, the sheath is bent and stretched, and a convex rib structure is arranged between the sheath and the elastic connecting piece, so that the sheath and the elastic connecting piece can be generated. The gap can increase the bending strength of the sheath and enhance the service life. In addition, the gap structure also makes the insertion and disassembly of the elastic connecting piece simpler, and the sheath and the elastic connecting piece are not closely attached and are difficult to disassemble.

 Compared with the prior art, the beneficial effects of the present invention are:

 Elastic USB of the invention The connecting piece can be separated from the base or the lamp cap, or the lamp cap can be directly inserted into the base for use, and the use is very flexible, and at the same time, since the three are detachable, the carrying is greatly facilitated.
