Background technique
Digital class battery small-sized at present uses steel ball to throw into liquid injection port substantially and is closed.And great-capacity power battery
Bad with steel ball sealing effect because liquid injection port is larger, the current liquid injection port of general power battery mostly uses laser welding to seal
Mouthful, with liquid injection port is exactly blocked using metal material shell as, intersection use laser by gap both sides metal molten and
Reach sealing effect.But in actual operation, often because of parameter in the pollution and welding of the impurity and weld of material
Variation and haves the defects that welding, generating stomata or crack leads to leakage, and leakage once occurs for lithium battery, say battery it is secondary
Product.General producer will carry out repair welding twice because once leakage, the stomata of weld occurs once the phenomenon of leakage occurs at present
Or created great difficulties by electrolyte contamination to repair welding at crack, even to carry out multiple repair welding just can solve problem to some, give
The normal production of battery is brought a lot of trouble.
Summary of the invention
The present invention is provided in the lower end of sealing end and squeezes out end, and making rubber sealing boot by extrusion end, deformation occurs
It is fitted on the inner wall of cover board, to be preferably sealed to liquid injection hole, plays the role of improving the practicality energy, provide
A kind of new energy resource power battery shell fluid injection seal assembly.
In order to solve the above technical problems, structure of the invention includes cover board, sealing cover, sealing end and rubber seal
Set, the cover board are weldingly fixed on the upper end of battery case, liquid injection hole are offered on the cover board, the liquid injection hole
Upper end offers connecting hole, and the sealing cover is mounted in connecting hole, and the sealing end is connected to the bottom of sealing cover,
The sealing end stretches in liquid injection hole, and the rubber sealing boot is wrapped on the surface of sealing end, the note
Fluid apertures is sealed by rubber sealing boot.
Further, the lower end shape spherical in shape of the sealing end.
Further: being provided with inscribed screw thread on the inner wall of the connecting hole, be arranged on the outer wall of the sealing cover
There is the external connection screw to match with inscribed screw thread, the sealing cover is by being inscribed the mating connection of screw thread and external connection screw even
It connects in hole.
Further: cavity is offered in the sealing end, one end that liquid injection hole is stretched out in the sealing end is opened
Equipped with pilot hole, it is connected in the pilot hole and squeezes out end, the extrusion end is stretched out under the action of extrusion mechanism
Pilot hole and outwardly against rubber sealing boot.
Further: the lower end shape spherical in shape of the sealing end.
Further: the extrusion mechanism includes screw rod and locking nut, and the locking nut is rotatably connected on lid
The top of plate, the screw rod cooperates and protrudes into sealing end with locking nut to be connected with extrusion end.
Further: one end shape spherical in shape for squeezing out end and stretching out pilot hole, the extrusion end and screw rod
One end of connection takes the form of inclined plane, and the screw rod is in coniform with one end that end is connect is squeezed out.
After adopting the above structure, the present invention is provided in the lower end of sealing end and squeezes out end, makes rubber by squeezing out end
Deformation occurs is fitted on the inner wall of cover board for glue sealing shroud, to preferably be sealed to liquid injection hole, plays raising in fact
With the effect of performance；And the design also has the advantages that structure is simple, easily fabricated and practical and efficient.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the structural diagram of the present invention.
