Abstract
The utility model relates to a power lithium battery threaded pole rotation stopping structure which comprises a threaded pole, the lower end of which is riveted and fixed on a battery cover plate; an insulating sealing gasket used for separating the threaded pole and the battery cover plate is arranged between the threaded pole and the battery cover plate; the upper end surface of the insulating sealing gasket is also pressed with a pressing ring; a groove is arranged on the end surface where the battery cover plate is contacted with the insulating sealing gasket; the insulating sealing gasket is correspondingly provided with a bulge which is matched in the groove; and continuous anti-skidding threads are arranged on the end surface where the pressing ring is contacted with the insulating sealing gasket. The insulating sealing gasket is matched with the battery cover plate by a concave-convex shifting position, and the anti-skidding threads are arranged between the pressing ring and the insulating sealing gasket for friction, so that the power lithium battery threaded pole rotation stopping structure is reasonable, ensures the threaded pole not to rotate when being applied with torsion force, can prevent sealing leakage and is safe and reliable for use.
Description
Technical field: the utility model relates to a kind of screw thread pole syndeton of dynamic lithium battery, particularly prevents the syndeton of rotating.
Background technology: the screw thread pole of general dynamic lithium battery all is that riveted is fixed on the battery cover board, and the riveted place accompanies the insulated enclosure pad simultaneously and separates insulation mutually.Because the screw thread pole all may be twisted in using wiring, riveted connects usually, and to reverse steadiness unreliable, and the screw thread pole might be rotated together with the insulated enclosure pad, causes the junction sealing leak, and battery liquid is leaked outside, even causes security incident.Even increase riveted power, its anti-rotation performance also is provided with obvious raising, also may make the insulated enclosure pad distortion of riveted place.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of dynamic lithium battery screw thread pole spline structure that can prevent that the screw thread pole from being twisted.
The utility model comprises that the lower end riveted is fixed on the screw thread pole on the battery cover board, being provided with the insulated enclosure pad between screw thread pole and battery cover board separates mutually, the upper surface of insulated enclosure pad also is pressed with trim ring, the end that contacts with the insulated enclosure pad on battery cover board is provided with groove, insulated enclosure pad then correspondence is provided with projection and places groove to cooperate, and the end that contacts of trim ring and insulated enclosure pad then is provided with continuous anti-skidding line.
There is concavo-convex gear to cooperate between insulated enclosure pad of the present utility model and the battery cover board surface, between trim ring and the insulated enclosure pad anti-skidding line friction is arranged also simultaneously, anti-rotation structure is reasonable, also can not be rotated when the screw thread pole is subjected to twisting resistance, prevent sealing leak, safe and reliable.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment;
Fig. 2 is the stereogram of trim ring;
Fig. 3 is another angle stereogram of Fig. 2;
Fig. 4 is the vertical view of battery cover board among Fig. 1;
Fig. 5 is another form figure of Fig. 4.
Embodiment: as shown in Figures 1 to 4, screw thread pole 1 lower end riveted is fixed on the battery cover board 2, is provided with insulated enclosure pad 3 and separates mutually between screw thread pole 1 and battery cover board 2, and the upper surface of insulated enclosure pad 3 also is pressed with trim ring 4.The end that contacts with insulated enclosure pad 3 on battery cover board 2 is provided with groove 5, and 3 correspondences of insulated enclosure pad are provided with projection 6 and place groove 5 to cooperate, and the end that contacts of trim ring 4 and insulated enclosure pad 3 then is provided with continuous anti-skidding line 7.Groove 5 can be located at the upper surface of battery cover board 2, also can all be provided with by upper and lower end face according to the spline performance need.And, also can be as shown in Figure 5, the groove 5 of battery cover board 2 adopts the groove groove, and the spline performance is stronger like this.
Present embodiment with trim ring 4 end faces of screw thread pole 1 riveted termination synapsis on, also be provided with several recesses 8 around endoporus edge, constitute riveted extruding tie point.When the assembling riveted, the riveted place of screw thread pole 1 has part to be pressed in the recess 8 of trim ring 4, makes trim ring 4 and screw thread pole 1 engaged like this, and structure is more reasonable, and the spline steadiness is better.
Claims (3)
1. dynamic lithium battery screw thread pole spline structure, comprise that the lower end riveted is fixed on the screw thread pole on the battery cover board, being provided with the insulated enclosure pad between screw thread pole and battery cover board separates mutually, the upper surface of insulated enclosure pad also is pressed with trim ring, it is characterized by: go up the end that contacts with insulated enclosure pad (3) at battery cover board (2) and be provided with groove (5), insulated enclosure pad (3) then correspondence is provided with projection (6) and places groove (5) to cooperate, and the end that contacts of trim ring (4) and insulated enclosure pad (3) then is provided with continuous anti-skidding line (7).
2. dynamic lithium battery screw thread pole spline structure according to claim 1 is characterized by: with trim ring (4) end face of screw thread pole (1) riveted termination synapsis on, also be provided with several recesses (8) around endoporus edge, constitute riveted extruding tie point.
