Embodiment
For the purpose of this utility model, technical scheme and advantage is more clearly understood, below in conjunction with specific embodiment, and
Referring to the drawings, the utility model is further described.But those skilled in the art know, the utility model is not limited to
Accompanying drawing and following examples.
The utility model embodiment proposes a kind of sealing structure of blood pressure measurement device, as shown in figure 1, including hard
Glue coupling 1 and flexible glue nipple 2, wherein ebonite coupling 1 include insertion section 11, stopper section 12,13 gentle circulation of connecting portion
Hole 14；The flexible glue nipple 2 includes connector portions 21 and cylindricality through hole 22, and connector portions 21 are enclosed into the cylindricality through hole 22.
In view of processing technology, preferably described cylindricality through hole 22 is cylindrical hole.
The ebonite coupling 1 axially inside forms the air-flow through hole 14.In order to reduce gas-flow resistance, the air-flow
The wall of through hole 14 is smooth surface.
The ebonite coupling 1 is sequentially arranged the insertion section 11, stopper section 12 and connecting portion 13 vertically.The insertion
Portion 11, stopper section 12 and connecting portion 13 can be integrally formed, and can also be sealed and are fixed together by the mode such as melting, gluing.
