[0003] As is known, power adapters need to be waterproofed. Therefore, most current power adapters are sealed and combined with an upper housing and a lower housing to protect internal components. However, for existing power adapters, especially those used outdoors, under the influence of rain and snow factors, moisture is likely to seep in from the joint between the upper housing and the lower housing, thus affecting the waterproof performance for outdoor use. Therefore, we propose a waterproof power adapter to solve the above problems.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a waterproof power adapter, which has the advantages of good waterproof performance for outdoor use, being convenient for disassembly, installation, and maintenance. To achieve the above purpose, the utility model proposes a waterproof power adapter, including a housing. A drawer that fits is slidably connected inside the housing. A circuit board is fixed on one surface of the drawer. A slot is opened on one inner wall of the housing. The drawer is provided with a limiting component for engaging with the slot. A wire management board is fixed on one surface of the drawer, and the wire management board is located below the circuit board. Two second T-shaped bars are symmetrically fixed on the other surface of the drawer. Two second T-shaped grooves that are adapted to the second T-shaped bars are symmetrically opened on the other inner wall of the housing. The two second T-shaped bars are respectively slidably connected in the corresponding second T-shaped grooves.

[0006] In one example, the housing is an integrally formed structure, and a positioning ring is fixed on the top of the housing.

[0007] In one example, the bottom of the drawer is located inside the housing, and a groove is opened at the bottom of the drawer.

[0008] In one example, the limiting component includes a first rubber ring fixed to the bottom of the drawer. A second rubber ring is in close contact with the bottom of the first rubber ring, and a rotating rod rotates in the middle of the first rubber ring and the second rubber ring.

[0009] In one example, the top of the rotating rod is rotatably connected to the bottom of the drawer through a bearing. A gear is sleeved and fixed on the surface of the rotating rod. The second rubber ring is fixed to the top of the gear. A rack is slidably connected to the bottom of the drawer. The rack meshes with the gear, and a knob is fixed to the bottom end of the rotating rod.

[0010] In one example, a first T-shaped bar is fixed to the top of the rack. A first T-shaped groove is formed in the bottom of the drawer. One end of the first T-shaped bar is fixed with a plug block adapted to the slot. The first T-shaped bar and the plug block are both slidably connected in the first T-shaped groove, and the position of the slot corresponds to that of the first T-shaped groove.

[0026] like Figures 1 to 5 As shown, an embodiment of the utility model proposes a waterproof power adapter, which includes a shell 1, a drawer 2 adapted thereto is slidably connected inside the shell 1, a circuit board 3 is fixed to one surface of the drawer 2, a slot 4 is provided on one inner wall of one side of the shell 1, a limit assembly 5 for engaging with the slot 4 is provided on the drawer 2, a wire management board 6 is fixed to one surface of the drawer 2, the wire management board 6 is located below the circuit board 3, two second T-bars 7 are symmetrically fixed to the other surface of the drawer 2, two second T-slots 8 adapted to the second T-bars 7 are symmetrically provided on the other inner wall of the shell 1, and the two second T-bars 7 are respectively slidably connected in the corresponding second T-slots 8.

[0027] Specifically, the housing 1 is an integrally formed structure, and a positioning ring 9 is fixed on the top of the housing 1 ; the positioning ring 9 facilitates personnel to fix and install the housing 1 .

[0028] Specifically, the bottom of the drawer 2 is located inside the outer shell 1, and a groove 10 is provided at the bottom of the drawer 2; the bottom of the drawer 2 is located inside the outer shell 1, which makes the bottom of the outer shell 1 longer than the bottom of the limited drawer 2, and can guide and drain rainwater, so that water is not easy to overflow upward from the gap between the drawer 2 and the outer shell 1. The groove 10 can provide a fulcrum for personnel when installing the drawer 2.

[0029] Specifically, the limiting component 5 includes a first rubber ring 501 fixed to the bottom of the drawer 2. The bottom of the first rubber ring 501 is in close contact with a second rubber ring 502. A rotating rod 503 rotates in the middle of the first rubber ring 501 and the second rubber ring 502. The close contact between the first rubber ring 501 and the second rubber ring 502 can play a damping role, making the rotating rod 503 not easily rotate, so that the limiting of the drawer 2 is relatively stable.

[0030] Specifically, the top of the rotating rod 503 is rotatably connected to the bottom of the drawer 2 through a bearing. A gear 504 is sleeved and fixed on the surface of the rotating rod 503. The second rubber ring 502 is fixed to the top of the gear 504. A rack 505 is slidably connected to the bottom of the drawer 2. The rack 505 meshes with the gear 504. A knob is fixed to the bottom end of the rotating rod 503. Personnel can directly rotate the rotating rod 503 through the knob, which can drive the gear 504 to rotate, and the gear 504 can drive the rack 505 to move correspondingly.

[0031] Specifically, a first T-shaped strip 506 is fixed to the top of the rack 505. A first T-shaped groove 507 is formed in the bottom of the drawer 2. One end of the first T-shaped strip 506 is fixed with a plug 508 adapted to the slot 4. The first T-shaped strip 506 and the plug 508 are both slidably connected in the first T-shaped groove 507. The positions of the slot 4 and the first T-shaped groove 507 correspond to each other. The first T-shaped strip 506 and the first T-shaped groove 507 can enable the rack 505 to slide smoothly at the bottom of the drawer 2, and the plug 508 moves correspondingly as the rack 505 and the first T-shaped strip 506 move. Cooperating with the slot 4, the disassembly and assembly of the drawer 2 can be realized.

[0032] Working principle: When in use, personnel can vertically install the power adapter at a suitable position through the positioning ring 9. In rainy and snowy weather, there are no gaps on the surface of the integrally formed housing 1, so rainwater will not penetrate into the housing 1. And the bottom of the housing 1 is longer than the bottom of the limited drawer 2, which can play a role in guiding and diverting rainwater, making it not easy for rainwater to overflow upward from the gap between the drawer 2 and the housing 1. When it is necessary to disassemble the drawer 2 for overhaul of the power adapter, personnel can turn the knob to drive the rotating rod 503 to rotate correspondingly. Due to the damping effect of the first rubber ring 501 and the second rubber ring 502, the rotating rod 503 will not easily rotate, improving the installation stability of the drawer 2. The rotating rotating rod 503 drives the gear 504 to rotate, and the gear 504 can drive the rack 505 to move correspondingly, which can drive the plug 508 in the first T-shaped groove 507 to move until the plug 508 disengages from the slot 4, and the drawer 2 can automatically slide out downward.

[0033] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple. For the relevant parts, reference can be made to the corresponding descriptions in the method embodiment.

[0034] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
