The following examples illustrate the detailed structure of the waterproof cover of the present application by way of example.

Referring to fig. 1-2, in this embodiment, the waterproof cover includes a base 100, a sealing ring, a sealing cover 300, a fastener 400, a first magnetic attraction member 500, and a second magnetic attraction member 600. The base 100 is provided with a avoidance through hole 121, the base 100 is fixed on the housing 001 through a fastener 400, and the avoidance through hole 121 is communicated with the insertion hole 002. The sealing ring is attached to the base 100, the avoidance through hole 121 is located in the area surrounded by the sealing ring, and the sealing ring is clamped between the shells 001 of the base 100. The sealing cover 300 is movably connected with the base 100, and the sealing cover 300 is used for opening or sealing the avoidance through hole 121. The first magnetic attraction piece 500 is installed on the base 100, the second magnetic attraction piece 600 is installed on the sealing cover 300, and when the sealing cover 300 is located at a position where the sealing is away from the through hole 121, the first magnetic attraction piece 500 and the second magnetic attraction piece 600 are magnetically attracted and connected.

Thus, the waterproof cover is additionally arranged on the shell 001, so that the shell 001 has the waterproof and dustproof functions, the shell 001 does not need to be replaced, and the modification of the shell 001 is small and the cost is low. Meanwhile, when the waterproof cover is in the state of sealing the jack 002, the base 100 and the sealing cover 300 are connected through the first magnetic attraction piece 500 and the second magnetic attraction piece 600, the matching of the sealing cover 300 and the base 100 is firm and reliable, the sealing is durable and the sealing effect is good.

Referring to fig. 1-2, in this embodiment, optionally, the base 100 includes an integrated socket 110 and a plate 120, the socket 110 is a circular cylinder, and the socket 110 is configured to be inserted into the jack 002. The plate body 120 may be a rectangular plate, the plate body 120 is fixedly connected with the housing 001 through the fastener 400, the avoiding through hole 121 penetrates through the plate body 120 and is communicated with the cylinder cavity of the insertion cylinder 110, and the sealing ring is clamped between the plate body 120 and the housing 001. The avoidance through hole 121 may be a circular hole, and is disposed coaxially with the barrel cavity of the insertion barrel 110 in an equal diameter. The diameter of the relief through hole 121 is the same as the diameter of the corresponding plug, and the insertion of the plug into the socket of the socket in the housing 001 is not affected. That is, in order to ensure that the plug is smoothly inserted into the socket after the base 100 is additionally provided, the original jack 002 can be enlarged when the socket 110 is installed, the position of the original jack 002 is replaced by the avoidance through hole 121, and when the plug is inserted into the socket, the plug passes through the avoidance through hole 121, so that the avoidance through hole 121 replaces the jack 002 to play a role in guiding and positioning the plug. And through inserting a section of thick bamboo 110 and jack 002 cooperation, can improve the fastness that base 100 and casing 001 combine to the sealing washer can cup joint outside inserting a section of thick bamboo 110, and the position of sealing washer is reliable and stable, and sealed effectual.

Referring to fig. 1-2, meanwhile, a sealing convex ring 123 and two fixing through holes 122 are disposed on the plate 120, the sealing convex ring 123 is convexly disposed on a plate surface of the plate 120 far away from the insertion barrel 110, and the sealing convex ring 123 is disposed around the avoidance through hole 121, where the sealing convex ring 123 may be a circular convex ring and coaxial with the avoidance through hole 121. The two fixing through holes 122 are circular holes, and each fixing hole is internally penetrated by a fastener 400, and the fastener 400 can be a self-tapping screw. When the base 100 and the shell 001 are assembled, the insertion cylinder 110 can be inserted into the insertion hole 002, the plate body 120 is matched with the base 100, the fastener 400 passes through the fixing through hole 122 and then is screwed into the shell 001 to realize fixed connection, or two threaded holes can be processed on the shell 001, and the fastener 400 passes through the fixing through hole 122 and then is screwed and fixed with the corresponding threaded hole. The number of the first magnetic attraction pieces 500 is two, and the two first magnetic attraction pieces 500 and the back-off 130 are positioned on the same side, and the two fixing through holes 122 are positioned on the other side.

Further, the socket 110 is provided with a reverse buckle 130 protruding from the outer circumferential surface of the socket 110. After the insertion tube 110 is inserted into the insertion hole 002 of the housing 001, the back-off 130 can be clamped with the inner wall surface of the housing 001, so that the base 100 is prevented from being directly separated from the insertion hole 002, and the combination stability is improved.

In addition, in other embodiments, a torsion spring may be disposed between the cover 310 and the base 100, where the torsion spring always causes the cover 310 to have a rotational tendency in a direction of sealing away from the through hole 121. Thus, after the plug is pulled out, under the action of the torsion spring, the cover body 310 can automatically close the avoidance through hole 121, so that the problem that the avoidance through hole 121 is forgotten to be closed is solved.

In this embodiment, alternatively, the sealing ring may be a rubber ring, and the cross-sectional shape of the sealing ring may be V-shaped, M-shaped, or O-shaped.

Referring to fig. 1-2, in this embodiment, optionally, the sealing cover 300 includes a cover body 310 and a sealing plug 320 that are vulcanized into an integral structure, the cover body 310 is rotatably connected with the base 100, and the cover body 310 drives the sealing plug 320 to rotate relative to the base 100, so that the sealing plug 320 is switched between the position of opening or sealing the avoidance through hole 121.
