Abstract

The utility model discloses a sealing structure of a sterilizer door. The sealing structure of the sterilizing door comprises a sterilizer door cover and a sealing ring; an annular inner groove is formed in the inner side wall of the sterilizer door cover and the section of the annular groove is a trapezoid with the upper end narrow and the lower end wide; the sealing ring is embedded in the annular groove, and the section of the sealing ring is of a trapezoid with the upper end narrow and the lower end wide. According to the sealing structure of the sterilizer door, the sealing ring and the sterilizer door cover are firm in combination and not prone to falling off.

Description

A kind of hermetically-sealed construction of sterilizer door
Technical field
The utility model relates to a kind of hermetically-sealed construction, particularly relates to a kind of hermetically-sealed construction of sterilizer door.
Background technology
General O RunddichtringO is for multiple watertight and airtight construction, but under hot environment, distortion easily appears in sealing ring, in general hermetically-sealed construction, the seal groove of placing sealing ring is all annular design, and the cross section of seal groove is rectangle, and the cross section of O RunddichtringO is circular, the high temperature deformation time, cross section is that the seal groove of rectangle can not play snap effect, causes sealing ring easily to come off due to sealing ring.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is that the sealing structure can make between sealing ring and device for door cover of sterilization and realize strong bonded, is not easy to come off for a kind of hermetically-sealed construction of sterilizer door is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of hermetically-sealed construction of sterilizer door, comprise device for door cover of sterilization and sealing ring; It is characterized in that: on the inside wall of device for door cover of sterilization, be provided with annular groove, the cross sectional shape of described annular groove is up-narrow and down-wide trapezoidal; Described sealing ring is embedded in described annular groove, and its cross sectional shape is up-narrow and down-wide trapezoidal.
Realize that the purpose of this utility model can also reach by taking following technical scheme:
Realize that a kind of embodiment of the present utility model is: described sealing ring is a kind of elastic silica gel sealing ring.
Realize that a kind of embodiment of the present utility model is: the lower hem width of the annular groove that described sterilizer door covers is than the short 0.1-0.2mm of the lower limb of sealing ring, and the upper hem width of annular groove is than the long 0.3mm of the top edge of sealing ring, this is the equipped parameter of the best of sterilizer main body and sealing ring, both can be conveniently assembled under this design, can better guarantee again sealing ring and sterilizer main body strong bonded.
Realize that a kind of embodiment of the present utility model is: the ratio of the depth of section of described annular groove and the depth of section of sealing ring is 7:8, the sealing effectiveness optimum, and sealing ring fastens more firm simultaneously.
The beneficial effects of the utility model are:
Up-narrow and down-wide trapezium structure is adopted in the cross section of the annular groove that sterilizer door described in the utility model covers, and up-narrow and down-wide trapezium structure is adopted in the cross section of sealing ring, when sealing ring during in high temperature deformation, can also make between sealing ring and sterilizer door and realize strong bonded, be not easy to come off.

Wherein, 1, device for door cover of sterilization, 2, sealing ring, 11, annular groove.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
Specific embodiment:
With reference to Fig. 1-5, the hermetically-sealed construction of the described sterilizer door of the present embodiment, comprise device for door cover of sterilization 1 and sealing ring 2; On the inside wall of device for door cover of sterilization 1, be provided with annular groove 11, the cross sectional shape of described annular groove 11 is up-narrow and down-wide trapezoidal; Described sealing ring 2 is embedded in described annular groove 11, and its cross sectional shape is up-narrow and down-wide trapezoidal.
Described sealing ring 2 is a kind of elastic silica gel sealing ring.
The lower hem width of the annular groove 11 on described device for door cover of sterilization 1 is than the short 0.1-0.2mm of the lower limb of sealing ring 2, and the upper hem width of annular groove 11 is than the long 0.3mm of the top edge of sealing ring 2, this is the equipped parameter of the best of sterilizer main body and sealing ring, both can be conveniently assembled under this design, can better guarantee again sealing ring and sterilizer main body strong bonded.
The ratio of the depth of section of the depth of section of described annular groove 11 and sealing ring 2 is 7:8, the sealing effectiveness optimum, and sealing ring fastens more firm simultaneously.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and the distortion all should belong to the protection domain of the utility model claim within.
