Description
Technical field
The present invention relates to rubber stopper technical field, a kind of new easy plug rubber stopper is particularly belonged to.
Background technology
The manufacturing of refrigerator needs the passage run as refrigerant with evaporator or condenser, to realize that refrigerator is cold
The function of cabinet refrigeration.Evaporator or condenser are that have metal pipe material (aluminum pipe, copper pipe, steel pipe) to be made, in order to ensure evaporator or
Condenser pipe end is stable with the refrigerant mozzle welding of compressor, while the holistic cost of evaporator or condenser is reduced again,
Evaporator or condenser tube end position are commonly copper pipe, and other positions are aluminum pipe steel pipe.In order to prevent other position aluminum pipes or steel
Inside pipe wall oxidation by air, needs to pouring high-purity nitrogen in pipeline, in pipeline in evaporator or condenser manufacturing process
Full of needed after nitrogen with rubber stopper block the mouth of pipe at.General Purpose Rubber plug there are problems that when in use：1, it is difficult to fill in pipe
It is difficult to extract in road or after filling in pipeline, using extremely inconvenient；2, sealing difference easily gas leakage；3, fill at the mouth of pipe of rubber stopper
Copper pipe is still exposed, and the copper pipe in evaporator or condenser transportation herein is easily touched flat or gouge.Therefore, our companies
It is proposed a kind of new easy plug rubber stopper.
The content of the invention
It is an object of the present invention to provide the new easy plug rubber stopper of one kind, it is possible to resolve the problem mentioned in above-mentioned background technology.
The technical solution adopted in the present invention is as follows：
A kind of new easy plug rubber stopper, it is characterized in that rubber stopper generally cylinder taper, rubber stopper is an entirety, bag
Plug top, cock body and plug tip are included, the plug top is generally cylindrical, upper top surface has circular groove, plug top is outer with cock body junction
Side periphery has circular groove, and plug top external diameter is more than cock body external diameter, and the cock body is located at below plug top, and cock body is generally hollow
Cylinder, is plug tip below cock body, and the plug tip is the hollow cone bodily form, and the upper top surface of plug tip is identical with the external diameter of cock body,
Plug tip bottom surface is equal with the external diameter of cock body hollow area, and hollow area is cylinder, two hollow area phases in the cock body and plug tip
It is intercommunicated to be integrated.
The cock body is connected transition region position with plug tip a few annular shallow concave grooves, cock body external diameter and the internal diameter for filling in tubing
It is equal.
Compared with the prior art, beneficial effects of the present invention are as follows：
The present invention is combined by the independent research decision design to rubber stopper entirety, plug top, cock body and plug tip, is solved general
Logical rubber stopper is difficult to fill in pipeline or is difficult to extract after filling in pipeline, using extremely inconvenient；Sealing difference easily gas leakage；Fill in
Copper pipe is still exposed at the mouth of pipe of rubber stopper, and the copper pipe in evaporator or condenser transportation herein is easily touched flat or gouge
Problem.There is circular groove around the lateral surface of plug top generally cylinder, plug top and cock body junction, using being cock body and plug
Point is filled in inside tubing, anti-in can be wrapped in for copper pipe at the mouth of pipe by the circular groove around plug top and cock body junction lateral surface
Only transportation copper pipe herein is touched flat or gouge；Using being can exert oneself extrusion plug top and cock body, inside cock body and plug tip
Cylindrical, hollow area deforms, and rubber stopper is easily filled in tubing, inserts rubber stopper to being inflated in tubing by Aerating needle, gas
Full of when tubing in hollow area of the gas full of tensioner cock body and plug tip, while cock body is connected transition region position with plug tip a few
Annular shallow concave groove, it is possible to increase the contact surface of rubber stopper and pipe material inner wall, increasing friction force, it is ensured that good seal performance, in pipeline
Gas is not easy leakage；When needing to extract rubber stopper, firmly extrusion plug top and cock body, in the cylinder inside cock body and plug tip
Dead zone gas is forced out, and whole rubber stopper integrally diminishes, and is easily extracted from tubing.Entirety of the invention is filled in and extracted easily,
Frictional force is big, and sealing is held one's breath, it is not easy to is revealed the gas in pipeline, is suitable as refrigerator evaporator or condenser end
Head copper pipe plug closes popularity and uses.
Brief description of the drawings
