Problems solved by technology

Although there is a reinforcing rib structure to make the assembly pressure of the battery plate group consistent up and down, the existence of the reinforcing rib causes uneven force between the plate and the side wall, which easily causes the side wall to bulge.

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 figure 2 image 3 Shown is an embodiment of a storage battery tank that prevents deformation of the short side walls of the present invention, which is made of acid-resistant plastic material, here is PP plastic material, including a rectangular tank box 1, and the four side walls of the tank box 1 are made of The short side wall 2 parallel to the plate surface and the long side wall 3 perpendicular to the plate surface are formed. Positioning slots 8 are provided on the inner sidewalls on both sides of the ridge line where the short sidewall 2 intersects with the long sidewall 3 . image 3 As shown in , the positioning groove 8 includes two parts, one part is the first groove 9 located on the short side wall 2 , and the other part is the second groove 10 located on the long side wall 3 . The anti-deformation elastic pressi...

Abstract

The invention discloses a storage battery groove for preventing deformation of short-edge side walls. Positioning grooves are formed in inner side walls at the periphery of two sides of ridges at which the short-edge side walls intersect long-edge side walls. Each positioning groove comprises two parts, namely a first groove formed in the corresponding short-edge side wall, and a second groove formed in the corresponding long-edge side wall; an anti-deformation elastic piece made of an acid resistance plastic material is arranged inside each positioning groove; each anti-deformation elastic piece comprises a support piece, an elastic piece and an adhesive-sealed butting piece; each support piece is in positioned connection inside the corresponding second groove and is leveled with the inner side wall of the corresponding long-edge side wall; each adhesive-sealed butting piece is in positioned connection inside the corresponding first groove and is leveled with the inner side wall of the corresponding short-edge side wall; the upper edges of the support pieces and the upper edges of the adhesive-sealed butting pieces are leveled with the upper edges of a groove box; each elastic piece can rotate to inside of the corresponding first groove by taking the cross line as an axis and is not protruded out of the inner side wall of the corresponding short-edge side wall. By adopting the structure, a phenomenon that the short-edge side walls swell and deform is avoided, the processing technology is simple, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of storage battery manufacturing, in particular to a storage battery tank capable of preventing short-side sidewalls from being deformed. Background technique [0002] For valve-regulated lead-acid batteries, applying sufficient pressure to the battery's pole group (composed of positive plates, negative plates, and separators) (this pressure is usually called assembly pressure) is an effective means to ensure battery life. Therefore, the valve-regulated lead-acid battery has a relatively high extreme group pressure when assembled to ensure the cycle life of the battery. Higher assembly pressure often leads to deformation of the short side wall of the battery tank parallel to the plate plane due to excessive force. In order to control the deformation of the short side wall of the battery tank, it is considered to design a thicker side wall of the battery tank, or to choose a plastic with better strength. Suc...
