The purpose of this utility model is the presence of the above problem in view of the prior art, it is proposed that between a kind of babinet and case lid
The outer container of the pump of good airproof performance.
The purpose of this utility model can be realized by following technical proposal：
A kind of outer container of pump, including babinet and case lid, which is characterized in that the outside of the case lid be equipped with along case lid it is radial to
The annular interconnecting piece of outer extension, the outer end of the interconnecting piece have the annular blocking portion for being parallel to case lid setting, the blocking
Annular groove is formed between portion, interconnecting piece and case lid, the opening portion of the babinet stretches in annular groove, in the annular groove
Equipped with sealing structure.
In a kind of outer container of above-mentioned pump, the sealing structure includes the ring type seal being set in annular groove, institute
There is annular slotted, the opening portion of the babinet, which is stretched, to be tightly fitted in fluting on the sealing ring stated.
In a kind of outer container of above-mentioned pump, the sealing ring has the ring being resisted against on case lid close to the side of case lid
Shape protrusion one, the annular protrusion one is obliquely installed and one end far from sealing ring extends to the opening side of annular groove.
In a kind of outer container of above-mentioned pump, the sealing ring has close to the side of blocking portion to be resisted against on blocking portion
Annular protrusion two.
A kind of outer container of pump, including babinet and case lid, which is characterized in that the outside of the babinet be equipped with along babinet it is radial to
The annular interconnecting piece of outer extension, the outer end of the interconnecting piece have the annular blocking portion for being parallel to babinet setting, the blocking
Annular groove is formed between portion, interconnecting piece and case lid, the opening portion of the case lid stretches in annular groove, in the annular groove
Equipped with sealing ring.
Compared with prior art, the outer container of this pump has the following advantages：
Due to being provided with annular protrusion one and annular protrusion two, the biradial sealing of sealing ring, sealed reliable are realized；And
And simple in structure, reasonable design, good appearance.
