Description

A kind of cell jar lid dense block buckle structure

Technical field

The utility model relates to a kind of storage battery product, especially relates to a kind of dense block buckle structure of cell jar lid.

Background technology

Lead acid accumulator needs sealing after injecting electrolyte, generally adopt a groove lid that can fasten sealing with battery case is set on battery case, groove covers and is provided with some liquid injection holes, put the rubber safety valve on the liquid injection hole to realize sealing to inside battery, cover cover plate of design at groove again, with the control safety valve normal open and close valve pressure is arranged, this cover plate adopts seal or ultrasonic wave sealing or heat-sealing that its position is fixed mostly, the shortcoming of this frame mode is that cover plate unloads difficulty, the working service of inconvenient battery.

Some battery is provided with caulking groove in the both sides of cell through lid, the cover plate side is provided with chimb, between cover plate and groove lid as drawer-type structure, push-and-pull just can realize between cover plate and the groove lid joint with separate, be convenient to the working service of battery, but its shortcoming is the cover plate easy deformation, thereby influence the operate as normal of its below safety valve, for solving this shortcoming, generally the device that covers other increase liquid feeding cap at groove guarantees the operate as normal of safety valve, but this frame mode production and processing technology complexity, the cost of goods manufactured height.

The utility model applicant discloses a kind of hermetically-sealed construction of cell jar lid in utility model patent ZL200420022906.5, form by groove lid that is tightly connected with cell jar upper end and the seal cover that is positioned at its upper end, the groove portion of covering has groove, opening of groove, both sides have caulking groove, corresponding side is provided with chimb on the seal cover, and seal cover can cover slot opening from groove and push in the groove, and chimb and caulking groove are sealed and matched.This utility model processing is simple, good airproof performance, easy installation and removal, but because of fit clearance between seal cover and groove lid smaller, in seal cover insertion groove lid process, the insertion end ratio of seal cover is easier to the damage safety valve, thereby influences the safety valve operate as normal, and only by positioning convex and location notch secure fit, seal cover is loosening easily to be out of shape between seal cover and groove lid.

Summary of the invention

The utility model provides a kind of groove lid and the close-fitting structure of its top cover labyrinth of lead acid accumulator, and this structure processing is simple, and seal cover cooperates compact with the groove lid, the gap is little, good airproof performance, and seal cover is difficult for loosening distortion, convenient disassembly is convenient to the working service of storage battery.

A kind of cell jar lid dense block buckle structure, form by groove lid that is tightly connected with cell jar upper end and the seal cover that is positioned at its upper end, groove covers and is provided with some liquid injection holes, be with safety valve on the liquid injection hole, the groove portion of covering has groove, opening of groove, both sides have caulking groove, seal cover both sides correspondence is provided with chimb, seal cover covers the slot opening end from groove and pushes in the groove, and chimb and caulking groove are sealed and matched, and is provided with inclined plane groove with the corresponding position of liquid injection hole on the inner surface of the insertion end of described seal cover, the rear portion of seal cover has hook, and groove covers slot opening end correspondence and is provided with and links up with the buckle inside groove that cooperates.

The insertion end of described seal cover is provided with chimb, and matching with chimb on the cell wall of groove lid groove is provided with slot.

The lower surface of described seal cover is provided with projection, and groove covers to match with projection and is provided with location notch.

The utility model matches the groove of seal cover and groove lid, by the caulking groove of groove and the chimb tabling of seal cover, seal cover is pushed in the groove of groove lid promptly salablely, and the mutual fastening by hook and buckle inside groove makes seal cover be fixed on groove to cover.Inclined plane groove on the seal cover insertion end inner surface, guarantee that seal cover can the damage safety valve when inserting, and be respectively equipped with chimb and projection on the insertion end of seal cover and the inner surface, groove covers corresponding slot and the location notch of being provided with, seal cover pushes in the groove lid, and chimb inserts in the slot, and projection is pressed in the location notch, make seal cover closely paste mutually, guarantee that seal cover can not become flexible distortion with the groove lid.

The utility model easy installation and removal pushes seal cover to put in place along groove lid caulking groove during installation the mutual fastening of hook and buckle inside groove is got final product; During dismounting, will link up with simultaneously and push inward, hook and buckle inside groove are thrown off after, can from groove covers, pull out seal cover.
