Description

The board plug type battery case lid

Technical field:

The utility model relates to a kind of battery case lid, particularly relates to a kind of board plug type battery case lid.

Background technology:

As everyone knows, battery case on the electric bicycle is by drain pan, middle cover and loam cake constitute, and middle cover covers then on drain pan,, in cover again and close the lid, the effect of loam cake mainly is to cover the vent valve of adding a cover on each liquid injection port in blocking to come off, at present, traditional method be with loam cake stick with glue in cover, during maintenance, must open loam cake, at this moment, can only pry open with screwdriver, therefore, loam cake and middle cover are very easily destroyed, and especially loam cake is easier to be destroyed, in case middle cover is destroyed, just can't continue to use, lose very big and cause waste, the loading and unloading difficulty of loam cake is lost time, manpower and financial resources.

Summary of the invention:

Main purpose of the present utility model is to overcome above deficiency and provides a kind of loam cake loading, unloading convenient, the maintenance efficiency that can improve easy to maintenance, the board plug type battery case lid that saves material.

The technical scheme that its technical problem that solves the utility model adopts is: it is made up of loam cake 1 and middle cover 2, it is characterized in that: loam cake 1 both sides sideband boss 3, one end has tongue 7, the back side has retaining projection 4, middle cover 2 has rim of the mouth 5 with loam cake 1 dual-side corresponding section, have back stop slot 6 with retaining projection 4 corresponding sections, loam cake 1 back side, one end of middle cover 2 has slot 8, the boss 3 of loam cake 1 dual-side directly inserts 5 places, rim of the mouth of middle cover 2, the tongue 7 of loam cake 1 end just in time inserts slot 8 places on the middle cover 2, the retaining projection 4 at loam cake 1 back side embeds in the back stop slot 6 on the middle cover 2.

Advantage and the good effect that the utlity model has are: the loading, unloading of loam cake 1 are convenient, are convenient to maintenance, improved operating efficiency, saved time and maintenance cost, and loam cake 1 can insert arbitrarily or pull out repeatedly and use, so labor and material saving is convenient to processing, cost is low.
