Abstract
The invention discloses a kind of improved lithium battery caps, including cap body, cross bumping post, several cone seal bodies and elastic piece, cross holding tank is opened up inside cap body, several air holes are opened up in cap body top sidewall, cross bumping post, which slides vertically, to be arranged in holding tank, elastic piece is resisted against at the top of cross bumping post, several air holes are located above elastic piece, multiple round tube holes are vertically opened up on cross bumping post, several cone seal bodies cooperation round tube hole is equidistantly fixed inside cap body, cone seal body seals round tube hole under original state, elastic piece blocks air hole.When atmospheric pressure is greater than external environment in the present invention, cross bumping post is jacked up upwards, round tube hole connection is internal, inner air is discharged into above cross bumping post by round tube hole, since active force of the cross bumping post to elastic piece exposes air hole, the case where inner air is discharged from air hole, avoids inside battery bulge generation.
Description
Technical field
The present invention relates to a kind of improved lithium battery caps, belong to lithium battery cap technical field.
Background technique
Lithium battery cap sealing performance in the prior art is general, while cannot effectively discharge inner air, hot weather
It is easy bulge, serious conditions can even jeopardize user's safety.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of existing technologies, a kind of improved lithium battery cap is provided
Cap can be avoided internal bulge.
In order to achieve the above objectives, the present invention provides a kind of improved lithium battery cap, including cap body, cross bumping post, several
A cone seal body and elastic piece open up cross holding tank inside the cap body, open up in the cap body top sidewall several
A air hole, the cross bumping post, which slides vertically, to be arranged in the holding tank, and the elastic piece is resisted against the cross bumping post
Top, several described air holes are located above the elastic piece, vertically open up multiple round tube holes on the cross bumping post,
Several described cone seal bodies cooperate the round tube hole to be equidistantly fixed inside the cap body, described under original state
Cone seal body seals the round tube hole, and elastic piece blocks air hole.
Preferentially, the elastic piece shape is cone shape, and elastic piece center bulging downwards forms hemisphere, described
Cross bumping post upper surface opens up the cooperation hemispheroidal holding tank.
Preferentially, the cross bumping post material is metal.
Preferentially, the cross bumping post shape is the cylinder that cross section is " ten " shape.
Preferentially, the round tube hole annular equidistantly distributed.
Preferentially, the air hole is V-arrangement.
Advantageous effects of the invention:
When atmospheric pressure is greater than external environment in the present invention, cross bumping post is jacked up upwards, and round tube hole connection is internal, internal empty
Gas is discharged into above cross bumping post by round tube hole, internal since active force of the cross bumping post to elastic piece exposes air hole
The case where air is discharged from air hole, avoids inside battery bulge generation.
Detailed description of the invention
Fig. 1 is sectional view of the invention.
Mark meaning in attached drawing, 1- cap body；2- cross bumping post；3- cone seal body；4- elastic piece；5- holding tank；6- is saturating
Stomata；7- round tube hole.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
A kind of improved lithium battery cap, including cap body 1, cross bumping post 2, several cone seal bodies 3 and elastic piece 4,
Cross holding tank 5 is opened up inside the cap body 1, opens up several air holes 6, the cross in 1 top sidewall of cap body
Bumping post 2, which slides vertically, to be arranged in the holding tank 5, and the elastic piece 4 is resisted against 2 top of cross bumping post, several institutes
It states air hole 6 and is located at 4 top of elastic piece, vertically open up multiple round tube holes 7 on the cross bumping post 2, several institutes
Stating cone seal body 3 cooperates the round tube hole 7 to be equidistantly fixed inside the cap body 1, the circular cone under original state
Seal 3 seals the round tube hole 7, and elastic piece 4 blocks air hole 6.
Further, 4 shape of elastic piece is cone shape, and the 4 center bulging downwards of elastic piece forms hemisphere,
2 upper surface of cross bumping post opens up the cooperation hemispheroidal holding tank.
Further, 2 material of cross bumping post is metal.
Further, 2 shape of cross bumping post is the cylinder that cross section is " ten " shape.
Further, the annular equidistantly distributed of the round tube hole 7.
Further, the air hole 6 is V-arrangement.
When atmospheric pressure is greater than external environment in the present invention, cross bumping post 2 is jacked up upwards, and round tube hole connection is internal,
Inner air is discharged into 2 top of cross bumping post by round tube hole, since active force of the cross bumping post 2 to elastic piece 4 makes air hole 6
The generation of the case where exposing, inner air is discharged from air hole 6, avoids inside battery bulge.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
