After the laptop is fully charged, the external power cord is taken out from the three-claw slot 5, and the parts of the waterproof mechanism 4 move down to fit the periphery of the three-claw slot 5. Under the action of the waterproof mechanism 4, water and other liquids can be prevented from entering the three-claw slot 5, thereby improving the waterproof performance of the power adapter.

[0031] Example 2

[0032] The present embodiment is different from the first embodiment in that the support assembly 6 includes a support rod 61, a fixing frame 62, a plug-in column 65 and a plug-in slot 66. The fixing frame 62 is connected to the side wall of the power adapter body 1 and is located between the waterproof mechanism 4 and the three-claw slot 5. The support rod 61 is plugged into the interior of the fixing frame 62. The support rod 61 and the fixing frame 62 are both provided with a plug-in slot 66. The plug-in columns 65 are plugged into the interior of the two plug-in slots 66.

[0033] Specifically, the support assembly 6 further includes a pull rod 63 and a second spring 64. The second spring 64 is connected between the support rod 61 and the fixed frame 62. The pull rod 63 is connected to one end of the support rod 61 and located inside the second spring 64.

[0034] By adopting the above technical solution, the pull rod 63 is pulled toward the periphery of the fixed frame 62, and the movement of the pull rod 63 drives the support rod 61 to move into the fixed frame 62, and the support rod 61 moves to squeeze the second spring 64. Subsequently, the pull rod 63 is released, and the second spring 64 loses the external force and returns to its original state, driving the support rod 61 to reset, thereby facilitating the storage and reset operations of the support rod 61.

[0035] When this embodiment is used and the three-claw slot 5 needs to be used, first pull the pull rod 63 toward the periphery of the fixed frame 62. The movement of the pull rod 63 drives the support rod 61 to move into the interior of the fixed frame 62. The support rod 61 moves to squeeze the second spring 64, and then the components of the waterproof mechanism 4 are moved up, so that the three-claw slot 5 is exposed to the outside. Then, release the pull rod 63, and the second spring 64 loses the external force and returns to its original state, driving the support rod 61 to move and reset. Under the action of the support rod 61, the components of the waterproof mechanism 4 can be supported to avoid the subsequent insertion of one end of the external power cord into the three-claw slot 5. The components of the waterproof mechanism 4 are not in contact with the external power cord, which affects the stability of the connection between the external power cord and the three-claw slot 5.

[0036] The structure and principle of the waterproof mechanism 4 composed of a box body, a pull plate, a baffle, a limit plate, a spring, and a rubber pad in the utility model have been disclosed in a waterproof power adapter disclosed in Chinese patent application No. 202223051137.9, and its working principle is: a box body is glued and connected to one side of the power adapter body 1 and located above the three-claw slot 5, springs are welded equidistantly on the top of the box body, and a baffle is welded to the bottom of the spring, the top of the baffle is located in the box body, a rubber pad is connected to the side wall of the baffle, a pull plate is connected to one end of the baffle away from the box body, and a spring is welded to the one side of the power adapter body 1 and located below the three-claw slot 5. When the limit plate is connected and the three-claw slot 5 needs to be used, the upward pull plate drives the baffle to move and be retracted into the box body, and the baffle moves to squeeze the spring. After the three-claw slot 5 is used, after the external power cord is taken out from the three-claw slot 5, the spring loses the external force and returns to its original state, driving the baffle to move away from the box body. The movement of the baffle drives the pull plate to move. When the pull plate moves to fit the limit plate, the pull plate is blocked and stops moving. At this time, the baffle covers the periphery of the three-claw slot 5. Under the action of the rubber pad, a gap between the baffle and the power adapter body 1 can be avoided. Under the action of the baffle, water and other liquids can be prevented from entering the three-claw slot 5, so as to improve the waterproof performance of the power adapter.

[0037] The working principle and use process of the utility model are as follows: the utility model first pulls the pull rod 63 toward the periphery of the fixed frame 62, and the movement of the pull rod 63 drives the support rod 61 to move and be collected into the fixed frame 62, and the support rod 61 moves to squeeze the second spring 64, and then moves the components of the waterproof mechanism 4 upward, so that the three-claw slot 5 is exposed to the outside, and then releases the pull rod 63, the second spring 64 loses the external force and restores its original appearance, driving the support rod 61 to move and reset, under the action of the support rod 61, the components of the waterproof mechanism 4 can be supported to avoid that after one end of the external power cord is subsequently inserted into the three-claw slot 5, the components of the waterproof mechanism 4 abut against the external power cord, affecting the stability of the connection between the external power cord and the three-claw slot 5, and then one end of the external power cord is inserted into the three-claw slot 5, and then the power cord is connected to the laptop computer, and then the wire 2 provided on the power adapter body 1 is connected to the city Electrical connection, charging operation for the laptop computer, after the wire 2 is connected to the mains, the movable frame 321 is squeezed by the connecting end of the mains and the wire 2 and moves toward the inside of the cavity 323, and the movable frame 321 moves to squeeze the first spring 324, and when the sealing ring 322 fits the connecting end of the mains and the wire 2, the movable frame 321 stops moving, and under the action of the connecting frame 31, the movable frame 321, the sealing ring 322 and the external frame 33, the connection between the wire 2 and the mains can be sealed to prevent water from the external environment from falling into the connection between the wire 2 and the mains to avoid danger. After the laptop computer is charged, the external power cord is taken out from the three-claw slot 5, and the components of the waterproof mechanism 4 move down and fit to the periphery of the three-claw slot 5. Under the action of the waterproof mechanism 4, water and other liquids can be prevented from entering the three-claw slot 5 to improve the waterproof performance of the power adapter.
