Abstract

A magnetic sealing device is applicable to be installed on an object which includes a main body and a connection part arranged on the main body. The connection part has a base, an accommodation space formed in the base, and an opening formed on the base to communicate the accommodation space with outside. The magnetic sealing device includes a sealing member, a first magnetic member connected to the base, and a second magnetic member connected to the sealing member and magnetically attractive to the first magnetic member. The sealing part can detachably abut the base and close the opening, and further tightly seal the opening by magnetic attraction force between the first magnetic member and the second magnetic member. Since the sealing member does not need to be embedded in the base, possibility of mutual abrasion between the sealing member and the base can be reduced, so as to extend service life.

Description

Magnetic sealing device

The present invention relates to a sealing device, and more particularly to a magnetic sealing device.

Generally, electronic products such as mobile phones are equipped with at least one signal hole for plugging in a signal line, in order to avoid corrosion of the signal hole due to long-term exposure to the air, which is easily contaminated by dust or moisture. Moreover, the contact with the signal line is poor, which affects the signal transmission. Therefore, the manufacturer has designed a dust cover that can cover the signal hole.

Referring to FIG. 1 , a dust cover 1 for covering a signal hole 21 of a mobile phone 2 is provided. The dust cover 1 includes a shielding plate 11 and a tenon 12 extending from the center of the shielding plate 11 to prevent dust. The protrusion 12 of the cover 1 is used to engage the signal hole 21, and the shielding plate 11 is used to close the signal hole 21, thereby preventing the signal hole 21 from being rusted due to long-term adhesion of dust or moisture in the air.

However, in use, the user often needs to pull the shielding plate 11 of the dust cover 1 to interlock the tenon 12 of the dustproof cover 1 from the signal hole 21, or push the shielding plate 11 to make the tenon 12 and the signal hole 21 The fitting is such that the tenon 12 needs to be frequently rubbed against the signal hole 21. Moreover, the use environment of the mobile phone 2 is often full of external forces of collision and vibration. Therefore, the dust cover 1 will be continuously worn under long-term use, thereby causing breakage or damage of the tenon 12 of the dust cover 1, and cannot be tight. The ground cover is embedded in the signal hole 21, and the dust cover 1 is thus lost due to loosening. In addition, when the tenon 12 is engaged in the signal hole 21, once it is broken or damaged, the card may be blocked. The signal hole 21 is inside and cannot be removed.

Accordingly, it is an object of the present invention to provide a magnetic sealing device which is less prone to wear and which can extend the service life.

Therefore, the magnetic sealing device of the present invention is suitable for being mounted on an object, the object comprising a body and a connecting portion disposed on the body, the connecting portion having a base and a base formed therein The accommodating space and an opening formed on the pedestal and allowing the accommodating space to communicate with the outside.

The magnetic sealing device comprises a sealing member, a first magnetic member and a second magnetic member. The sealing member is detachably abutted against the base of the connecting portion and used to close the opening of the connecting portion, and the first magnetic member is connected to the base of the connecting portion. The second magnetic member is connected to the sealing member and is magnetically attracted to the first magnetic member. When the sealing member is detachably abutted on the base and closes the opening of the connecting portion, the first magnetic member can be The magnetic attraction between the second magnetic member and the second magnetic member causes the seal to more closely close the opening.

The invention has the effect that the sealing member can more closely close the opening by the magnetic attraction between the first magnetic member and the second magnetic member, and can avoid the sealing member and the base of the connecting portion. Wear occurs, which in turn extends the life of the magnetic seal.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of FIG.

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

The user can control the button 442. Driving the circuit board 441 controls the first magnetic member 42 to open and close its magnetic properties, but the controller 44 is not limited to the magnetic connection of the first magnetic member 42. For example, it can also be controlled by wireless control. The magnetic properties of the first magnetic member 42.

In addition, the first magnetic member 42 and the second magnetic member 43 are not limited to the above, for example, the first magnetic member 42 may be an electromagnet, and the second magnetic member 43 is a permanent magnet. At this time, the magnetic property of the second magnetic member 43 can be controlled by the controller 44; or the first magnetic member 42 and the second magnetic member 43 are both permanent magnets, and the magnetic sealing device 4 does not include control. And the first magnetic member 42 and the second magnetic member 43 are all electromagnets, and the controller 44 controls the magnetic properties of the first magnetic member 42 and the second magnetic member 43 respectively.

When the connecting portion 32 is idle, the sealing member 41 of the magnetic sealing device 4 can be adhered to the base 321 of the connecting portion 32 by its contact surface 412 and close the opening 323, while driving the button 442 to drive the button The circuit board 441 controls the first magnetic member 42 to generate magnetism that can attract the second magnetic member 43, so that the seal 41 more closely closes the opening 323.

In addition, by operating the button 442, the circuit board 441 can be easily driven to control the magnetic property of the first magnetic member 42 to cancel the magnetic attraction force between the first magnetic member 42 and the second magnetic member 43. Therefore, the user can easily remove the sealing member 41 so that the accommodating space 322 communicates with the outside, so that the connector (not shown) of the signal line is inserted.

(2) can prevent the seal from loosening and falling:

If the sealing member 41 is damaged by the collision and pulling of the external environment, the sealing member 41 can be closely abutted against the base 321 by its own viscous property and the magnetic attraction force. The risk of the seal 41 being lost due to loosening is avoided.

Referring to FIG. 5, a second preferred embodiment of the present invention is substantially the same as the first preferred embodiment. The difference is that the accommodating space 322 includes a large aperture area 3221 communicating with the opening 323, and a small aperture area 3222 that communicates with the large aperture area 3221. The first magnetic member 42 is in the form of a ring and is disposed in the large aperture area 3221 of the receiving space 322 of the connecting portion 32. A connector (not shown) can be inserted through the first magnetic member 42 to electrically connect to the small aperture region 3222 of the accommodating space 322, thereby also achieving the same effect as the first preferred embodiment in use. Moreover, compared with the first preferred embodiment, the mounting of the first magnetic member 42 of the preferred embodiment is simpler, thereby reducing manufacturing costs.

Referring to FIG. 7, a third preferred embodiment of the present invention is substantially the same as the first preferred embodiment. The difference is that the first magnetic member 42 is disposed outside the base 321 so as to be used. The same effect as the first preferred embodiment can also be achieved. Furthermore, the mounting of the first magnetic member 42 of the preferred embodiment is simpler than the first preferred embodiment, thereby reducing manufacturing costs. Thereby providing another embodiment.
