Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a notebook computer interface dust keeper, includes shell 1, and shell 1 inner chamber lower extreme fixed mounting has bayonet joint 2 between two parties, and 2 bilateral symmetry of bayonet joint are provided with dust absorption mechanism 3, and shell 1 upper end and bayonet joint 2 correspond the position and open there is the socket, and socket bilateral symmetry installs dustproof mechanism 4, passes through first spout 5 sliding connection between dustproof mechanism 4 and the shell 1 upper end.

Dustproof mechanism 4 comprises first spring 41, dust guard 43 and connecting rod 42, and first spring 41 one end and shell 1 inner wall fixed connection, the other end and dust guard 43 back fixed connection, and dust guard 43 top fixed mounting has connecting rod 42, sliding connection between connecting rod 42 and first spout 5, and connecting rod 42 upper end is provided with stopper 6, and dust guard 43 openly sets up to the profile of tooth, intermeshing between two dust guards 43.

It should be noted that, because two dust guard plates 43 can be engaged with each other, the dust guard plates 43 and the first spring 41 are mutually matched to ensure that the inner cavity of the housing 1 can be protected by the dust guard plates 43 when the interface is not used, so as to prevent dust from falling into the inner cavity and affecting the use of the interface.

The dust collection mechanism 3 is composed of an air bag 31, a second spring 33, a second chute 34, a support frame 35 and a limit plate 32, the support frame 35 is symmetrically and fixedly installed on two sides of the plug connector 2, the support frame 35 is fixedly connected with the inner wall of the shell 1, one end of the second spring 33 is fixedly connected with the upper end of the support frame 35, the other end of the second spring 33 is fixedly connected with the upper end of the limit plate 32, the second chute 34 is arranged on the support frame 35 in the vertical direction, the limit plate 32 is in sliding connection between the support frames 35 through the second chute 34, specifically, the limit plate 32 is arranged corresponding to the plug, and when the plug is inserted into the interface, the limit plate 32 can be; the air bag 31 is made of elastic rubber materials, the upper end of the air bag 31 is connected with the limiting plate 32 in a gluing mode, and the lower end of the air bag 31 is connected with the lower end of the interior of the shell 1 in a gluing mode.

It is worth noting that, because the interface of the notebook computer is frequently plugged and unplugged, although the dustproof plate 43 can protect the interface from dust entering when the interface is not used, some dust is always brought into the interface when the interface is plugged and unplugged, the air bag 31 arranged in the dust suction mechanism 3 can suck the dust in the inner cavity of the shell 1 into the air bag 31 when the plug is unplugged, and when the plug is plugged into the interface, the dust sucked in the air bag 31 is discharged to the outside of the interface, thereby ensuring the normal use of the interface inside the interface.

The two sides of the air bag 31 are provided with one-way valves 7, one-way valve 7 penetrates through the support frame 35 and is arranged in the inner cavity of the shell 1, the other one-way valve 7 penetrates through the shell 1 and is arranged outside the shell 1, the two one-way valves 7 are arranged in opposite directions, and the air bag 31 can only suck dust from the inner cavity of the shell 1 and then discharge the dust from the outside of the shell 1; specifically, because the directions of the check valves 7 on the two sides of the air bag 31 are opposite, the check valves 7 arranged inside the interface can ensure that negative pressure is formed inside the air bag 31 when the volume of the air bag 31 is increased, and dust can only enter the air bag 31 from the inside of the interface and cannot be discharged reversely; the one-way valve 7 arranged outside the housing 1 can ensure that when the connector is inserted into the interface, the air pressure inside the air bag 31 is larger than the external air pressure due to the volume reduction of the air bag 31, and the dust inside the air bag 31 can be discharged to the outside from the air bag 31 under the driving of the air flow, and can not be reversely sucked from the outside.

Now, the operation principle of the present invention is described as follows:

when a plug needs to be inserted into the interface, the two dustproof plates 43 are firstly opened by sliding the limiting block 6 on the connecting rod 42 in the first sliding groove 5, so that the plug 1 can be inserted between the two dustproof plates 43; when the plug continuously moves downwards, the limiting plates 32 arranged on the two sides of the plug 2 can be driven to synchronously slide downwards through the second sliding chutes 34, the downwards-moving limiting plates 32 can extrude the air bag 31, so that the volume of the air bag 31 is reduced, the air pressure in the air bag 31 is larger than the external air pressure, dust in the air bag 31 can be discharged from the air bag 31 under the driving of air flow, and the directions of the check valves 7 arranged on the two sides of the air bag 31 are opposite, so that the air bag 31 can only suck the dust in the inner cavity of the shell 1 and then discharge the dust from the outside of the shell 1; when the plug is used and needs to be pulled out, the dust-proof plate 43 and the limiting plate 32 are not limited any more by the plug, the limiting plate 32 can be reset under the action of the second spring 33, meanwhile, the volume of the air bag 31 is increased, negative pressure can be generated inside the air bag 31, so that dust brought in the inner cavity of the shell 1 in the inserting and pulling process of the socket is sucked into the air bag 31, and the dust is prevented from affecting the use of the interface; the dust guard 43 realizes resetting synchronously under the action of the first spring 41, so that the two dust guards 43 are kept in an engaged state, the interface is ensured to be protected by the dust guard 43 when not used, and the dust guard 43 can prevent dust from falling into the inner cavity to influence the use of the interface.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
