Description
Technical field
The utility model relates to a kind of lithium ion battery, especially relates to a kind of lithium ion battery group Bolt Connection locking device.
Background technique
Lithium ion battery is owing to have stable, the advantages such as volume is little, long service life, environmental protection of high-energy-density, discharge voltage; Be applied to gradually in electric bicycle, electric bicycle and the portable power tool in recent years, also be expected to one of major impetus power supply that becomes following power vehicle.The lithium-ion-power cell group of electric bicycle or automobile power source in use causes between bolt assembly the mutual rotation of self easily owing to reasons such as vibrations, collisions; Make nut loosening; Even come off; Cause to connect not firmly between the cell of battery pack, influence the usability and the working life of battery.
In order to prevent that nut loosening from coming off, people usually are employed in the strip groove that is provided with on the double-screw bolt of bolt assembly with central axes, and the internal thread hole of inside and outside wall to perforation is set on the wall body of nut.Screw passes the internal thread hole, in the groove that trailer card is preset on screw column, tightens screw, with double-screw bolt and nut locking.There is following problem in this locking device: fluting on the screw column and on the nut wall body reach through hole, all can destroy the screw thread of a part, screw thread damages easily, stripped thread thereby make, working life is short, anti-loose effect is limited.In addition, internal thread hole on the nut and the groove on the double-screw bolt are wanted accurate contraposition, have certain degree of difficulty in the operation.Moreover, reach through hole and tapping on the less nut wall body of size, also have certain difficulty of processing, machining accuracy there is certain requirement, as: can influence the cooperation of nut and double-screw bolt etc. to destroying internal thread and causing the internal thread edge deformation during processing through hole.
The model utility content
The utility model technical problem to be solved provides and a kind ofly can effectively prevent relatively rotating between bolts and nuts, anti-loose effective lithium ion battery group Bolt Connection locking device.
In order to solve the problems of the technologies described above; The lithium ion battery group Bolt Connection locking device that the utility model provides comprises double-screw bolt and nut, and described double-screw bolt is provided with a circular radial through hole; One end face of described nut is provided with concave station; The internal diameter of described concave station is provided with to organize identical restraining grooves along the circle spacing greater than the external diameter of described double-screw bolt on the wall body of described concave station more, and a spacing latch is arranged in the described circular radial through hole and its termination is in the described restraining groove.
Described spacing latch is riveted on the described double-screw bolt.
Described restraining groove is that the medial axis angle of adjacent described U-shaped restraining groove is 60 ° along even 3 groups 6 the identical U-shaped restraining grooves that are provided with at interval of the wall body circumferencial direction of described concave station.
Described spacing latch is made up of greater than the head of described cylindrical shaft a cylindrical shaft and a diameter; The diameter of the head of described spacing latch is less than the width of the described restraining groove diameter greater than described circular radial through hole, and the cylindrical shaft of described spacing latch does not have the gap with described round tube hole and cooperates.
Adopt the lithium ion battery group Bolt Connection locking device of technique scheme; End face at nut is provided with concave station; The concave station inwall does not have screw thread, and on the concave station wall body, along the circumferential direction is arranged at intervals with three groups of identical U-shaped restraining grooves, need not to destroy the worm structure in the nut; Help realizing good cooperation the between nut and double-screw bolt, avoided the appearance of sliding tooth silk situation; Being symmetrical set of three groups of U-shaped restraining grooves makes that the required regulation range of nut narrows down to 60 °, is convenient to the accurate contraposition of the circular radial through hole on U-shaped restraining groove and the double-screw bolt when there is deviation in the contraposition of the circular radial through hole on U-shaped restraining groove and the double-screw bolt.The utility model is reasonable in design, and is simple in structure, easy to process; Use flexibly, locking effect is good, can effectively prevent in vibration environment; Because of rotating nut loosening that causes even situation about coming off generation each other, it is firm, reliable to have guaranteed that battery pack connects between bolt assembly.
In sum, the utility model is a kind of reasonable in design, simple in structure, easy to operate, can effectively prevent relatively rotating between bolts and nuts, anti-loose effective lithium ion battery group Bolt Connection locking device.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; Plate 5 adopts two spring pads 4 and nut 2 to be installed on the double-screw bolt 1; Double-screw bolt 1 is provided with a circular radial through hole 11, and an end face of nut 2 is provided with concave station 21, and the internal diameter of concave station 21 is greater than the external diameter of double-screw bolt 1; Wall body circumferencial direction along concave station 21 evenly is arranged at intervals with 3 groups 6 identical U-shaped restraining grooves 22; The medial axis angle of adjacent U-shaped restraining groove 22 is 60 °, and spacing latch 3 adopts the softer metals of material such as Cuprum alloy or aluminum alloy to process, and spacing latch 3 is made up of greater than the head 31 of cylindrical shaft 32 cylindrical shaft 32 and a diameter; The diameter of the head 31 of spacing latch 3 is less than the width of U-shaped restraining groove 22 diameter greater than circular radial through hole 11; The cylindrical shaft 32 of spacing latch 3 cooperates with round tube hole 11 no gaps, and spacing latch 3 is arranged in the circular radial through hole 11, and spacing latch 3 two are riveted on the double-screw bolt 1 and its two terminations all are in the U-shaped restraining groove 22.
