Description

Technical Field

[0001] The utility model relates to the field of POE power supply, and more specifically, to a portable POE power supply. Background Art

[0002] POE power supply means that without making any changes to the existing Ethernet Cat.5 cabling infrastructure, it can provide DC power to some IP-based terminals such as IP phones, wireless LAN access points AP, network cameras, etc. while transmitting data signals for such devices.

[0003] In order to facilitate carrying the POE power supply, the power cord of the POE power supply needs to be folded. The POE power supply with a separate power cord and power supply on the market needs to carry the power cord and the POE power supply at the same time. A storage slot for accommodating the power cord is provided on the POE power supply, and the power cord is placed in the storage slot, so that the POE power supply is convenient to carry. However, when the POE power supply needs to be carried, the user needs to roll up or fold the power cord in a certain way before putting it into the storage slot, which is very inconvenient. Moreover, if the power cord is rolled up or folded incorrectly, the power cord will get tangled in the storage slot, which is inconvenient for next use. The POE power supply with a single power supply and power cord on the market usually By winding the power cord around a reel and rotating the reel to retract the power cord, the POE power supply can be easily carried. However, the user is required to manually rotate the reel to retract the power cord. For example, a Chinese utility model patent discloses a portable POE power supply module (application number: CN202021901801.2). The worm drives the worm gear to rotate by rotating the knob, and the worm gear drives the shaft wheel to rotate, so that the power wire is wound around the shaft. At this time, the power wire is shortened, but the user is required to keep turning the knob to shorten the power wire, which is very time-consuming and laborious. This makes it inconvenient for users to carry the POE power supply. Utility Model Content

The power cord 20 is wound on the winding drum 5. The winding drum 5 is provided with baffles 50 at both ends of its axial direction. The baffle 50 is divided into a front baffle and a rear baffle, that is, the front end of the winding drum 5 is fixedly connected to the front baffle, and the rear end of the winding drum 5 is fixedly connected to the rear baffle. Two sliding rods 51 located on the left and right sides of the front end surface are provided on the front end surface of the front baffle. The two sliding rods 51 are slidably connected to a first end face ratchet 52, and each of the sliding rods 51 is sleeved with a spring 5 located between the first end face ratchet 52 and the baffle 50. 4. The end face of the first end face ratchet 52 where the gear teeth are located faces away from the baffle 50, that is, the end face of the first end face ratchet 52 where the gear teeth are located faces the front side. Two extension plates 53 are extended radially outward on the side wall of the first end face ratchet 52. The two extension plates 53 correspond to the two slide bars 51 one by one, that is, the left and right sides of the side wall of the first end face ratchet 52 are respectively extended with extension plates 53, and each of the extension plates 53 is provided with an extension plate through hole. The slide bar 51 is inserted into the corresponding extension plate through hole. The spring 54 is located between the extension plate 53 and the baffle 50. The first end face ratchet 52 is provided with a spring on the front end face that drives the first end face ratchet 52 to move along the slide bar 51 is a sliding button column 55, and the button column 55 is located at the center of the first end face ratchet 52.
