Description

Lead storage battery cover body Technical Field The utility model relates to the technical field of storage batteries, in particular to a lead storage battery cover body. Background In the production process of the lead-acid storage battery, glue is filled at the bottom of the cover body of the lead-acid storage battery so as to facilitate connection of other parts and improve the safety performance of the lead-acid storage battery. When the cover body adopted in the prior art is filled with glue, due to the limitation of the shape of the cover body, all grooves of the cover body are of a structure which is mutually separated, and the sizes of the grooves are different, so that the glue adding amount in each groove is different, the accurate control of the filling amount is required when the glue is added, otherwise, the shortage or the excessive addition of the glue in part of the grooves can be caused, the shrinkage deformation of the cover body can be caused if the filling amount is insufficient, and the overflow of the glue to the place where the cover body does not need to be filled with the glue can be caused if the filling amount is excessive, both the two conditions can influence the quality of a product, the size of part of the grooves is small and deep, the gas in part of the grooves is difficult to completely discharge, the phenomenon that the glue overflows can occur in a cavity, the material of the cover body is usually plastic, and the shrinkage deformation of the cover body can be caused once the cavity appears, so that the appearance of the cover body does not meet the production requirements. Disclosure of utility model In order to overcome the defects of the related prior art, the application provides the lead storage battery cover body, which can reduce the possibility of generating a cavity in the cover body, avoid overflow, improve the production yield and have stronger practicability. In order to achieve the above object, the present utility model adopts the following technique: a lead storage battery cover body comprises a cover plate. The two sides of the bottom surface of the cover plate are respectively provided with a plurality of first grooves which are arranged at intervals along the length direction of the cover plate, a plurality of second grooves which are arranged at intervals along the length direction of the cover plate are arranged between two rows of first grooves, long grooves which are arranged along the arrangement direction of the cover plate are respectively arranged between the first grooves and the second grooves, a plurality of partition boards are arranged in the long grooves along the length direction of the long grooves, a space is reserved between one end of each partition board, which is far away from the second groove, and the first grooves, partition grooves are respectively arranged between two adjacent first grooves, the depth of each partition groove is larger than that of the long groove, and the tops of the partition grooves are communicated with the long grooves.
