Abstract
The utility model relates to a kettle with an improved rotary capping sealing structure, which comprises a kettle body and a kettle cover, wherein a kettle head of the kettle body is assembled and connected with a kettle plug of the kettle cover by a sealing ring in a rotary capping sealing way; a ring-shaped groove provided with an opening arranged downwards is directly molded on the sealing ring; a round corner is arranged at the periphery of the lower end of the sealing ring; and a tapered step with a taper angle is arranged at the part where the kettle head is contacted with the sealing ring. The kettle has the advantage of being labor-saving during rotary capping.
Description
Technical field
The utility model relates to the improved kettle of a kind of spiral cover hermetically-sealed construction.
Background technology
Existing kettle, comprise kettle body and pot lid, spiral cover sealing assembling is connected the kettle head of kettle body by sealing ring with the kettle plug of pot lid, and upward lower plane is stressed contacts but its sealing ring adopts with the contact site of kettle head, rely on the last lower compression of sealing ring to play sealing, so the spiral cover effort.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems, and a kind of spiral cover labour-saving kettle is provided.
The purpose of this utility model is to realize like this, comprise kettle body and pot lid, spiral cover sealing assembling is connected the kettle head of kettle body by sealing ring with the kettle plug of pot lid, the sealing ring straight forming has downward opening cannelure, the lower end periphery of sealing ring is provided with fillet, and the contact site of kettle head and sealing ring is provided with the type conical bench of taper angle.
The utility model, the tapering of taper angle are 45 ~ 60 degree.
The utility model, sealing ring are buckled by dogging shoulder and are located at kettle beyond the Great Wall.
The utility model, different with the spiral cover hermetically-sealed construction of existing kettle, owing to downward opening cannelure is arranged at the sealing ring straight forming, kettle head and the contact site of sealing ring are provided with the type conical bench of taper angle, when spiral cover, rely on the oblique pressure of type conical bench, cannelure is shunk, with the compression seal up and down of the alternative traditional sealing ring of the radial compression sealing of sealing ring, so spiral cover is laborsaving.Has spiral cover labour-saving advantage.
Following embodiment is further described the utility model in conjunction with the accompanying drawings.
Description of drawings
The bulk-breaking structural representation of Fig. 1 embodiment of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of the A portion of Fig. 1 embodiment.
Among the figure, 1, the kettle body; 2, pot lid; 3, kettle head; 4, kettle plug; 5, sealing ring; 6, cannelure; 7, fillet; 8, contact site; 9, type conical bench; 10, dogging shoulder; α, taper angle.
The specific embodiment
With reference to Fig. 1, Fig. 2, present embodiment comprises kettle body 1 and pot lid 2, spiral cover sealing assembling is connected the kettle head 3 of kettle body by sealing ring 5 with the kettle plug 4 of pot lid, sealing ring 5 straight formings have downward opening cannelure 6, the lower end periphery of sealing ring is provided with fillet 7, and the contact site 8 of kettle head 3 and sealing ring is provided with the type conical bench 9 of conicity angles alpha; The tapering of conicity angles alpha is 45 degree; Sealing ring 5 is buckled by dogging shoulder 10 and is located on the kettle plug 4.
When the utility model uses, when spiral cover, rely on the oblique pressure of type conical bench 9, cannelure 6 is shunk, and the avris radial compression of sealing ring 5 is so spiral cover is laborsaving, when conicity angles alpha is 45 when spending, on the comparable conventional planar sealing ring spiral cover of lower compression laborsaving half; Dogging shoulder 10 makes sealing ring 5 be convenient to be located on the kettle plug 4.
