Abstract
The utility model relates to a kind of seal ring, comprises the matrix of ring-type, the upper-end surface of described matrix with lower end surface is equipped with the linear sealing coordinated with described matrix phase.The utility model by being provided with linear sealing in the upper and lower surface of matrix, make seal ring yielding, work good with tank surface, good sealing effect, prevent from, because casing internal pressure is excessive and occur the situation of pressure release, reducing the requirement to tank surface processing technology simultaneously.
Description
Technical field
The utility model relates to the seal ring sealed junction surface, is specifically related to a kind of seal ring for the sealing of animal plethysmography box.
Background technique
At present, when test experience animal lung ventilatory function (as: airway resistance, lung compliance etc.), need to ensure must to ensure in plethysmography box completely airtight, relevant parameter could be obtained, seal ring can be lined with between the case lid and casing of plethysmography box, because the restriction of existing processing technology, the casing of plethysmography box is difficult to be processed into plane, the air spots of casing.Existing seal ring is face sealing, is out of shape little, therefore causes the situation of pressure release.
Model utility content
The purpose of this utility model is to provide a kind of seal ring for plethysmography box, by being provided with linear sealing, makes seal ring yielding, thus prevents the situation of pressure release, reduce the requirement to tank surface processing technology simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A kind of seal ring, comprises the matrix of ring-type, the upper-end surface of described matrix with lower end surface is equipped with the linear sealing coordinated with described matrix phase.
Further, the sectional shape of described matrix is rectangular loop, for being provided with the animal volume markings case of rectangular opening.
Further, the flex point place of described matrix is circular arc, makes the bearing capacity at flex point place identical with the bearing capacity on border, good sealing effect.
Further, the sectional shape of described linear sealing is semicircle, realizes linear sealing, good processing.
Further, described linear sealing is symmetrical arranged on the matrix, and double-layer seal increases sealing effect, simultaneously for support substrate, makes inside and outside two lateral balances of matrix.
The beneficial effects of the utility model are: the utility model by being provided with linear sealing in the upper and lower surface of matrix, make seal ring yielding, work good with tank surface, good sealing effect, prevent from, because casing internal pressure is excessive and occur the situation of pressure release, reducing the requirement to tank surface processing technology simultaneously.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of seal ring described in the utility model embodiment;
Fig. 2 be in Fig. 1 A-A to sectional view.
Embodiment
As shown in Figure 1-2, a kind of seal ring described in the utility model embodiment, comprise matrix 1, the sectional shape of described matrix 1 is rectangular loop, the flex point place 3 of described matrix 1 is circular arc, the upper-end surface of described matrix with lower end surface is equipped with the linear sealing 2 coordinated with described matrix phase, the sectional shape of described linear sealing 2 is semicircle, and described linear sealing 2 is symmetricly set on described matrix 1.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technological scheme, all drops within protection domain of the present utility model.
Claims (5)
1. a seal ring, comprises the matrix of ring-type, it is characterized in that: the upper-end surface of described matrix with lower end surface is equipped with the linear sealing coordinated with described matrix phase.
