Abstract

The utility model discloses a cover sealing structure. The cover sealing structure comprises a container and a cover, wherein the cover and an opening of the container are in threaded connection, the inner wall of the top part of the cover is provided with a sealing convex ring and a sealing convex plate, the sealing convex plate is encircled outside the sealing convex plate so as to form an annular groove, which is used for the opening edge of the container to be embedded in, between the sealing convex ring and the sealing convex plate, the sealing convex ring is obliquely arranged towards the outer side, a first annular bulge is formed on the outer side of the sealing convex ring, the first annular bulge and the inner side wall of the opening of the container are in contact sealing, the outer side wall of the annular groove is a conical surface, the conical surface and the outer side of the opening of the container are in contact sealing, a second annular bulge is formed on the side wall of the top part of the cover by the annular groove, and the second annular bulge and the outer sideend face of the opening of the container are in contact sealing. Due to the technical scheme, three-stage sealing is arranged, a maze structure is formed, thus the sealing effect is fully ensured, the leakage is prevented, the sealing contact parts is inadopt line contact sealing, the structure is simple, the implementation is easy, and the manufacturing cost is low.

Description

The sealing of lid structure

Technical field

The utility model relates to a kind of lid, relates in particular to the hermetically-sealed construction of lid and vessel port.

Background technology

In the prior art, have and adopt lid and vessel port screw connection structure, lid generally plays support and airtight container opening, and can hermetically-sealed construction wherein effective sealing, most important.In the existing structure design, after the pipe lid screws with body, generally realize sealing with the madial wall flush fit of vessel port by the sealing bulge loop that is located on the cap top inwall, sealing effectiveness is relatively poor like this.Also have by realizing sealing between vessel port end face and the cap top inwall, but sealing effectiveness is also not satisfactory.

Summary of the invention

In order to solve above-mentioned technical matters, the purpose of this utility model provides a kind of sealing of lid structure with better sealing effectiveness.

To achieve the above object, the utility model has adopted following technical scheme:

The sealing of lid structure, comprise container and lid, described lid is threaded with vessel port, described cap top inwall is provided with sealing bulge loop and seal boss, between forms the circular groove that can supply the vessel port edge to embed thereby seal boss is looped around sealing bulge loop outside, described sealing bulge loop is obliquely installed laterally and forms the first annular protrusion in its outside, this first annular protrusion contacts sealing with the vessel port madial wall, the lateral wall of described circular groove is the conical surface, the outer side contacts sealing of this conical surface and vessel port, this circular groove is formed with the second annular protrusion at the wall of cap top side, and this second annular protrusion contacts sealing with the vessel port end face.

The utility model arranges three grades of sealings and consists of labyrinth structure owing to adopted above technical scheme, has fully guaranteed sealing effectiveness, avoids seepage, and the sealing contact site is line contact sealing, and is simple in structure, is easy to realize low cost of manufacture.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.

Embodiment 1:

A kind of sealing of lid structure as shown in Figure 1, comprise container 2 and lid 1, described lid 1 is threaded with vessel port 21, as shown in Figure 2, described cap top 11 inwalls are provided with sealing bulge loop 12 and

seal boss

15,12 outside betweens form the circular groove 13 that can supply vessel port 21 edges to embed thereby seal boss 15 is looped around the sealing bulge loop, described sealing bulge loop 12 is obliquely installed laterally and forms the first annular protrusion 16 in its outside, this first annular protrusion 16 contacts sealing with vessel port 21 madial walls, the lateral wall of described circular groove 13 is the conical surface, this conical surface and vessel port 21 outer side contacts sealings, this circular groove 13 is formed with the second annular protrusion 14 at the wall of cap top 11 sides, this second annular protrusion 14 and the sealing of vessel port 21 end contacts.

It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
