Specific embodiment
Following embodiment only exists in illustrative purpose, limits the scope of the invention without being intended to.
In the description of the present invention, it is to be understood that, term " on ", "lower", "front", "rear", "left", "right", "top",
The orientation or positional relationship of the instructions such as "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
Embodiment:
Referring to Fig.1-3, a kind of easily to pull out safety plug, including plug, plug includes matrix 1 and is circumferentially uniformly embedded in matrix
Three pin ends 2 of 1 bottom end, are of course not solely limited to three pin plug, can also be two-line plug, the periphery wall week of matrix 1
To multiple notches 3 are uniformly provided with, the equal gluing of inner wall of each notch 3 has pressing utricule 4, is filled with memory sponge in pressing utricule 4,
Memory sponge has shape memory function, and reset can be automatically performed after pressing, offers in matrix 1 and number and pressing utricule 4
The interface channel 1 of arc, the both ends of interface channel 1 are connected to two adjacent pressing utricules 4 respectively, the bottom end of matrix 1
And holding tank 7 is offered at the middle part of three pin ends 2,7 interior folding of holding tank is accommodated with press part 8, and press part 8 is mounted on base
The purpose at the middle part of body 1 is to allow multiple 2 uniform forces of pin end, and 1 inner circumferential of matrix is uniformly provided with and presses utricule 4 and is connected to
Interface channel 29；
The bottom of press part 8 is equipped with hand-operated valve 10, the middle part of interface channel 1 be communicated be in communication with the outside it is external
Pipe, and the end of extension tube attached is equipped with air and is only capable of the check valve one for being circulated to interface channel 1 from the external world, pressing utricule 4, even
Air is installed in connection road 29 and is only capable of the check valve two being circulated in press part 8 from interface channel 1, pressing utricule 4, is led to
The setting for crossing check valve 1 and check valve two defines the circulating direction of air, it is ensured that easily pulls out the normal use of safety socket.
In the present invention, press part 8 includes multiple ring bodies 81 that from top to bottom internal diameter linearly increases, and each ring body 81 is outer
Diameter, which is respectively less than, is located at the internal diameter of its lower end ring body 81, between every two adjacent ring body 81, is located at topmost and the lowermost ring
The equal gluing of 81 inner wall of body has a folding utricule 82 of micro- bullet, ring body 81 and folds utricule 82 and collectively forms sealing space, in press part 8
Multiple ring bodies 81 by fold utricule 82 successively fold and store into holding tank 7, the top of press part 8 is glued at holding tank
On 7 inner roof wall, the structural principle of upper press part 8 is similar with the structural principle of bellows in the prior art, but slightly different.
In the present invention, height value when the entirely pneumatic state of sealing space is greater than the length of pin end 2, it is ensured that sealing space
When entirely pneumatic, plug can pull away socket completely.
In the present invention, the internal diameter of holding tank 7 is greater than the outer diameter for being located at the lowermost ring body 81 in press part 8, and holding tank 7 is complete
Press part 8 can be stored entirely.
After easily pulling out safety plug using this, the clamping force between plug and socket is larger, In for electric appliance and equipment
This, substitutes more unsafe method directly to pull the plug out of the socket in the prior art by following application methods:
Pressing utricule 4 is intermittently pressed using finger first, when pressing the contraction of utricule 4, inner air is only capable of passing through
Interface channel 29 is filled in the sealing space in press part 8, since memory sponge has auto-reset function, memory sponge from
Pressing utricule 4 is propped up under dynamic reset, and under the action of extraneous atmospheric pressure, air is circulated to connection automatically by extension tube attached
In channel 1 and pressing utricule 4, continuing aforesaid operations can strut completely the sealing space in press part 8, in this process
In, multiple ring bodies 81 are successively detached from, positioned at the lowermost ring body 81 to female contact and generate compress power, generation compresses
After power, the height value of press part 8 constantly increases, in the dual work for compressing the spacing between power and matrix 1 and socket and constantly increasing
Under, multiple pin ends 2 in plug can it is laborsaving, safely extract socket；
In the process, multiple ring bodies 81 are successively detached from, positioned at the lowermost ring body 81 to female contact and producing
Raw to compress power, after generation compresses power, the height value of press part 8 constantly increases, and is compressing the spacing between power and matrix 1 and socket
Under ever-expanding double action, multiple pin ends 2 in plug can it is laborsaving, safely extract socket.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
