Problems solved by technology

When the lid is sealed with glue, glue overflows at the joint between the barrel body and the upper lid, which needs to be wiped off manually; moreover, in the groove, the amount of glue is too much, and due to the insertion of the guide piece, a large amount of glue will overflow, wasting materials and manpower , increasing the production cost

Embodiment Construction

[0012] The embodiments and positive effects of the present invention will be further described below.

[0013] As shown in the figure, a boss 3 is added in the U-shaped groove at the joint between the groove 2 on the back of the upper cover 1 and the U-shaped groove 1, and there is a boss 3 on both sides of each groove 2, and the height of the boss is U-shaped. About half of the depth of the groove; a gap 5 is opened at the barrel body II corresponding to the barrel wall, the width is slightly greater than the thickness of the boss 3, and the depth is consistent with the height of the boss, so as to ensure that the cooperation between the barrel and the upper cover is not affected.

[0014] When sealing with glue, first pour the glue into the U-shaped groove 1 of the upper cover, the height of the boss is the height of the poured glue, and the excess glue will flow into the groove 2 to ensure that the amount of glue is not excessive. Then pour the glue into the groove 2, e...

Abstract

The invention provides a lead-acid storage battery housing structure consisting of an upper cover and a barrel body, wherein the back of the upper cover is provided with U-shaped grooves and concave troughs; as an improvement, each U-shaped groove is internally provided with a boss in the part connected with the corresponding concave trough, and the height of each boss is less than the depth of each U-shaped groove. The corresponding parts of the barrel wall of the barrel body are provided with notches, and the inner walls of the concave troughs are marked with scales. According to the invention, a glue solution poured into the U-shaped grooves and the concave troughs of the upper cover can be controlled quantitatively at the time of glue sealing of the barrel cover so as to avoid glue overflow when a conductive lead piece is inserted into the barrel wall of the barrel body, reduce waste, lower frequency of manual frictioning, and cut production cost.

Description

technical field [0001] The invention relates to a shell structure of a lead-acid battery, belonging to the technical field of lead-acid batteries. Background technique [0002] The lead-acid battery shell is one of the necessary components for the battery. Its structure is generally made of PP and ABS materials, and is divided into two parts: the upper cover and the barrel. The upper cover and the barrel are generally sealed with epoxy resin glue, first pour the glue into the U-shaped groove of the upper cover, then turn the barrel 180°, insert the upper end of the barrel into the U-shaped groove of the upper cover to form a seal . At present, for manufacturers of multi-cell batteries in the storage battery industry, the guide parts between the cells are generally higher than the upper plane of the battery barrel, and there is a groove on the upper cover of the battery correspondingly. Due to the large volume of the guide parts , so the corresponding groove volume is also ...
