[0031] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example:

[0033] like Figures 1 to 4 As shown, a waterproof handle comprises: an upper cover 1 and a lower cover 2, which are connected by bolts to form a closed space. A circuit board 3 is arranged between the upper cover 1 and the lower cover 2, an annular protective plate 11 is arranged inside the upper cover 1, the circuit board 3 is located inside the annular protective plate 11, the circuit board 3 is connected to a wiring harness 4, and the wiring harness 4 passes through the annular protective plate 11 and is connected to the circuit board 3.

[0034] Among them, a convex ring 21 is provided at the lower cover 2 corresponding to the annular protective plate 11, and a first rubber gasket 5 is provided between the lower cover 2 and the annular protective plate 11. The first rubber gasket 5 is squeezed when the bolts are tightened on the upper cover 1 and the lower cover 2, thereby improving the sealing between the lower cover 2 and the annular protective plate 11, and sealing the circuit board 3 between the upper cover 1, the annular protective plate 11 and the lower cover 2, thereby improving the overall sealing.

[0035] In this embodiment, a rubber groove 51 is provided on the first rubber gasket 5 for the annular protective plate 11 to be embedded in, thereby increasing the contact area between the annular protective plate 11 and the first rubber gasket 5, improving the sealing performance, and preventing the rubber groove 51 from shifting during use. The passage path between the first rubber gasket 5 and the annular protective plate 11 is changed to an S-shape, making it more difficult for moisture or air to pass through, thereby further improving the sealing performance of the handle.

[0036] In this embodiment, the wire harness body 4 is sleeved with a second rubber gasket 6 at the annular protective plate 11 , thereby improving the sealing between the wire harness body 4 and the annular protective plate 11 , thereby improving the overall waterproofness.

[0037] In this embodiment, the annular protective plate 11 has a hole for placing the second rubber gasket 6. When the harness body 4 passes through the second rubber gasket 6, the second rubber gasket 6 is squeezed to make an interference fit between the harness body 4, the second rubber gasket 6 and the annular protective plate 11, thereby improving the sealing between the harness body 4, the annular protective plate 11 and the second rubber gasket 6, thereby improving the overall sealing of the waterproof handle. Among them, the outer side of the second rubber gasket 6 is provided with an annular groove 61 for the annular protective plate 11 to be embedded.

[0038] The lower cover 2 is provided with an anti-lost sheet 7 on the side facing the circuit board 3 to adsorb the lower cover 2 onto an external magnet. When not in use, the waterproof handle of the present application is placed on the magnet, and the anti-lost sheet 7 is adsorbed onto the magnet, thereby adsorbing the waterproof handle onto the magnet to prevent the waterproof handle from being lost.

[0039] In summary, the first rubber gasket 5 improves the sealing between the internal circuit board 3 and the annular protective plate 11 and the convex ring 21, thereby improving the waterproofness of the handle of the present application. The second rubber gasket 6 improves the sealing between the wiring harness body 4, the second rubber gasket 6 and the annular protective plate 11, thereby improving the waterproofness of the handle of the present application.

[0040] The various devices selected in this application are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
