It is convenient to use and has a reasonable design and is more applicable.

[0032] See also Figures 3 to 6 A waterproof component 12 is rotatably installed inside the sealed bearing 9. The waterproof component 12 includes a turntable 1201 and a through hole 1202. The turntable 1201 is rotatably installed inside the hole in the sealed bearing 9, and the turntable 1201 is coaxially rotated and driven with the winding drum 1105 through the transmission rod 1104, and a through hole 1202 is opened in the middle of the turntable 1201. The through hole 1202 sequentially penetrates the transmission rod 1104 and the winding drum 1105, and the inner diameter of the through hole 1202 is greater than the diameter of the core rod 1008. The waterproof component 12 also includes a swing arm 1203, a connecting rod 1204, a protective cover 1205 and a slider 1206. The swing arms 1203 are fixed on both sides of the outer edge of the rotating disk 1201, and the swing arms 1203 are rotatably connected to the connecting rod 1204. The end of the connecting rod 1204 away from the swing arm 1203 is rotatably connected to the bottom of the end of the protective cover 1205. The protective cover 1205 is slidably matched with the limiting groove 7 through the sliders 1206 on both sides of the root, and the protective cover 1205 covers the lead holes 2 at both ends of the housing 1 in the extended state.

[0033] The specific operation is as follows: while the winding drum 1105 rotates to produce wire, the winding drum 1105 synchronously drives the turntable 1201 located in the sealed bearing 9 to rotate through the transmission rod 1104, and the swing arms 1203 fixed on both sides of the outer edge of the turntable 1201 are further transmitted to the protective covers 1205 on both sides through the connecting rod 1204, so that the protective covers 1205 located at both ends of the casing 1 synchronously protrude outward. In this way, when the power adapter of the present application is used outdoors, the lead holes 2 at both ends of the casing 1 and the heat dissipation holes adjacent thereto can be physically shielded and protected to prevent rainwater from entering the casing 1 through the lead holes 2 or the heat dissipation holes and causing a short circuit in the circuit board 3. The deployment of the protective cover 1205 of the present application is carried out synchronously with the self-rotation process of the winding drum 1105 to produce wire, and the user does not need to perform additional deployment operations of the protective cover 1205. The linkage design simplifies the operating steps and improves the functionality and applicability of the power adapter of the present application.

[0034] In summary, when using the power adapter with waterproof wire storage function, hold the connecting terminal 1109 and pull out the wire harness 1108 from the lead holes 2 at both ends of the casing 1. While the winding drum 1105 rotates to draw out the wire, on the one hand, the winding drum 1105 drives the spiral spring 1103 inside the end seat 1101 to curl and store energy through the top plug 1106. On the other hand, the ratchet 1107 on the bottom of the winding drum 1105 intermittently engages with the lower ratchet 1006 on the top of the opening seat 1005 through the ratchet teeth, which can prevent the winding drum 1105 from uncontrollably reversing and resetting under the action of the resetting force of the spiral spring 1103 after the user lets go, thereby causing the connecting terminal 1109 to detach from the adapter connected thereto. The present application reels the adapter cable originally exposed to the outside into the housing 1 through the winding drum 1105, making the appearance of the housing more concise and convenient for wire collection. When in use, the wire harness 1108 wound on the winding drum 1105 is pulled out from the lead holes 2 at both ends of the housing 1 by holding the connecting terminal 1109, and the reverse resetting is prevented under the bite action of the ratchet wheels at the upper and lower ends. The application is convenient to use and the design is reasonable, and the applicability is stronger. When the winding drum 1105 rotates to draw out the wire, the winding drum 1105 synchronously drives the turntable 1201 located in the sealed bearing 9 to rotate through the transmission rod 1104, and the swing arms 1203 fixed on both sides of the outer edge of the turntable 1201 are further rotated to The protective covers 1205 on both sides are driven so that the protective covers 1205 at both ends of the casing 1 are synchronously protruded outward. In this way, when the power adapter of the present application is used outdoors, the lead holes 2 at both ends of the casing 1 and the heat dissipation holes adjacent thereto can be physically shielded and protected to prevent rain from entering the casing 1 through the lead holes 2 or the heat dissipation holes and causing a short circuit in the circuit board 3. The deployment of the protective cover 1205 of the present application is synchronized with the self-rotation and wire-out process of the winding drum 1105, and the user does not need to perform additional deployment operations of the protective cover 1205. The linkage design simplifies the operating steps, thereby improving the functionality and applicability of the power adapter of the present application. The top of the core rod 1008 is movably connected to the ball seat 1009 There is a ball-head hook 1010, which is convenient for the user to hang the power adapter of the present application on the handlebar or hook to meet the usage requirements of different scenarios. After use, the user presses down the core rod 1008 so that the core rod 1008 presses down the lower ratchet 1006 on the top of the open seat 1005 through the through hole 1202 that passes through the turntable 1201, the transmission rod 1104 and the winding wheel, so that the ratchet on the top of the lower ratchet 1006 disengages from the engagement with the upper ratchet 1107 at the bottom of the winding drum 1105, and the winding drum 1105 reverses under the reset force of the spiral spring 1103, thereby completing the automatic winding of the wiring harness 1108, so that the power adapter of the present application has the function of automatic winding, which is more convenient to use.
