Abstract
The utility model 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 utility model, 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 utility model 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.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of improved lithium battery
Nut cap can be avoided internal bulge.
In order to achieve the above objectives, the utility model provides a kind of improved lithium battery cap, including cap body, cross bumping post,
Several cone seal bodies and elastic piece open up cross holding tank inside the cap body, open up in the cap body top sidewall
Several air holes, the cross bumping post, which slides vertically, to be arranged in the holding tank, and the elastic piece is resisted against the cross
At the top of bumping post, several described air holes are located above the elastic piece, vertically open up multiple circles on the cross bumping post
Through-hole, several described cone seal bodies cooperate the round tube hole to be equidistantly fixed inside the cap body, original state
Under the cone seal body seal the round tube hole, 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.
The utility model it is achieved the utility model has the advantages that
When atmospheric pressure is greater than external environment in the utility model, cross bumping post is jacked up upwards, in round tube hole connection
Portion, inner air is discharged into above cross bumping post by round tube hole, since active force of the cross bumping post to elastic piece makes air hole
The generation of the case where exposing, inner air is discharged from air hole, avoids inside battery bulge.
Detailed description of the invention
Fig. 1 is the sectional view of the utility model.
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 utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
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 utility model, cross bumping post 2 is jacked up upwards, in round tube hole connection
Portion, 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 to breathe freely
The case where hole 6 is exposed, and inner air is discharged from air hole 6, avoids inside battery bulge generation.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
