Abstract
The utility model relates to a vent plug of a storage battery; the vent plug comprises a plug body; the plug body is provided with a port and an inner cavity, and a vent; a vent inner core which is provided with a vent channel is fixedly inlaid in the inner cavity of the plug body; the outer wall of the vent inner cover is tightly sealed with the inner cavity of the plug body; the external end surfaces of the plug body, which are connected with the vent inner core, are sealed and welded together; the inner cavity of the plug body is provided with an elastic valve cover which is embedded and pressed on the head end of the vent inner core and seals the vent channel; the elastic valve core is provided with an air flue; and the head of the elastic valve cover is propped against a preset boss of the inner cavity of the plug body. Compared with existing comparable products, the vent plug of the storage battery has the advantages that the structure is simple, parts are few, size and precision requirements on the parts are lower in production, the assembly is convenient, and the production cost of the product is greatly reduced.
Description
Technical field
The utility model relates to a kind of storage battery venting plug.
Background technology
Existing storage battery venting plug structure is comparatively complicated, and the dimension precision requirement to parts during manufacturing is very high, and assembling is very inconvenience also, often need therefore cause production cost of products higher by special tool(s).
The utility model content
The technical problem that the utility model will solve is: for solving the problem that existing storage battery venting plug product exists complex structure,, assembling difficulty big, production cost higher defective higher to the element size required precision; And a kind of simple structure, lower to the dimension precision requirement of parts, simple and convenient assembly, the storage battery venting plug that production cost is lower are provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of storage battery venting plug; It includes cock body, and cock body has port and inner chamber, and has exhaust outlet; Fixedly be equipped with exhaust inner core in the cock body inner chamber with exhaust passage; The outer wall of exhaust inner core and the internal chamber wall of cock body are close to sealing, and the outer end face seal that cock body and exhaust inner core join is integrally welded, are provided with embedding at the cock body inner chamber and are pressed in the elasticity valve gap that exhaust inner core head end is sealed its exhaust passage; The elasticity valve gap has air flue, and the boss that the head of elasticity valve gap and cock body inner chamber preset pushes against.This storage battery venting plug is after being installed on the storage battery; Pushed up from exhaust inner core head end end face when the plug internal gas pressure side that the elasticity valve gap has an air flue when reaching certain value and to be formed the gap, thereby accumulated in that gas in the exhaust passage of exhaust inner core releases and from the gap via the exhaust outlet discharge of cock body.
Say that further the boss of said cock body inner chamber and cock body are one.
In order to realize the sealing welding of the outside end face that said cock body and exhaust inner core join better, to guarantee the sealing of venting plug inner chamber, the outside end face that cock body and exhaust inner core join is integrally welded through annular auxiliary sealing.
Described cock body and exhaust inner core are moulding, to be more conducive to production.
The beneficial effect of the utility model is: this storage battery venting plug is compared with existing like product, and advantage is its simple structure, and parts are few, and the dimension precision requirement to parts during production is lower, simple and convenient assembly, and production cost of products significantly reduces.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the sectional structure sketch map of the utility model.
Among the figure: 1. cock body 1-1. exhaust outlet 1-2. boss 2. exhaust inner core 2-1. exhaust passages 3. elasticity valve gap 3-1. air flues
Embodiment
A kind of storage battery venting plug, as shown in Figure 1, it includes cock body 1; Cock body 1 has port and inner chamber; And have exhaust outlet 1-1, and fixedly being equipped with exhaust inner core 2 in cock body 1 inner chamber with exhaust passage 2-1, the internal chamber wall of the outer wall of exhaust inner core 2 and cock body 1 is close to sealing; Cock body 1 is integrally welded with the outer end face seal that exhaust inner core 2 joins; Be provided with embedding at cock body 1 inner chamber and be pressed in the elasticity valve gap 3 that exhaust inner core 2 head ends are sealed its exhaust passage 2-1, elasticity valve gap 3 has air flue 3-1, and the boss 1-2 that the head of elasticity valve gap 3 and cock body 1 inner chamber preset pushes against.
The boss 1-2 and the cock body 1 of cock body 1 inner chamber are one.Cock body 1 is integrally welded through annular auxiliary sealing with the outside end face that exhaust inner core 2 joins.Cock body 1 is moulding with exhaust inner core 2.
This storage battery venting plug is after being installed on the storage battery; Pushed up from exhaust inner core 2 head end end faces when the plug internal gas pressure side that elasticity valve gap 3 has air flue 3-1 when reaching certain value and to be formed the gap, thereby accumulate in that gas in the exhaust passage 2-1 of exhaust inner core 2 releases and discharge from the gap via the exhaust outlet 1-1 of cock body 1.
