Technical field
The utility model relates to the bindiny mechanism of vehicle air conditioner, particularly for the cooling system of the dual circuit pressing plate linkage structure mouth that is tightly connected.
Background technique
On the installation manufacturing line of vehicle, on selecting, the Placement on the air-conditioning system guarantees that for an entity bolt fastening mode is than more urgent with craving for of the fastening mode of moment of torsion.When addressing this problem, often adopt peanut shaped or square pressing plate form.
Different refrigerant types, R12 for example, R134a and CO2 are used in the air conditioner cooling system of vehicle.In any case the idea of environmental protection prosecutes to the end.As solution, for example the related proxy department of government of US and European has all passed through relevant supervision rules, is limited in the leakage rate limit of freezing mixture in the whole cooling system running with this.
Connecting format with double sealing structure is used to reduce the leakage in the air-conditioning system.These main structural types comprise forms such as rubber o-ring and hot solids Sealing.In any case, As time goes on, these parts are finally understood degradation failure.The damage of sealing configuration occurs in improperly installation or the handling process simultaneously.
This just need to produce a kind of cooling system that can reduce to greatest extent the refrigerant loss in air-conditioning system running mouth that is tightly connected.
The model utility content
The purpose of this utility model is to provide a kind of cooling system mouth that is tightly connected, and can reduce to greatest extent the refrigerant loss in the air-conditioning system running.
To achieve these goals, the technical solution of the utility model is: a kind of cooling system mouth that is tightly connected, comprise plug-in type pressing plate, receiving type pressing plate, plug-in type pressing plate and receiving type pressing plate are equipped with inner tube, it is characterized in that this plug-in type pressing plate is provided with an elongation zone, an end opening of the inner tube of described plug-in type pressing plate is positioned at the elongation zone; This receiving type pressing plate is provided with the depressed area corresponding with the elongation zone, one end opening of the inner tube of described receiving type pressing plate is positioned at the depressed area, insert in the depressed area of receiving type pressing plate the elongation zone of described plug-in type pressing plate, the inner tube of this plug-in type pressing plate matches with the inner tube of receiving type pressing plate, and be provided with seal ring between the inner tube of described plug-in type pressing plate and receiving type pressing plate, be connected with bolt between this plug-in type pressing plate and the receiving type pressing plate.The inner tube end face periphery of this plug-in type pressing plate is provided with ring shape projection, and the inner tube end face periphery of described receiving type pressing plate is provided with the annular recess that matches with this annular protrusion, and the annular protrusion of this plug-in type pressing plate is positioned at the annular recess of receiving type pressing plate.The inner tube end face of described plug-in type pressing plate is provided with a depressed part, and the inner tube end face of receiving type pressing plate also is provided with corresponding depressed part, and seal ring is between described two depressed parts.
The annular protrusion of described plug-in type pressing plate is inserted in the annular recess of receiving type pressing plate, and be provided with seal ring between described annular protrusion and the annular recess, then by bolt plug-in type pressing plate and receiving type pressing plate are tightened.Then the first seal area of seal ring is positioned at two pressing plate inner tube joints, and the second seal area is positioned at the groove that inserts pressing plate and inner tube formation.With bolt tightening, sealing gasket can be compressed, play seal action, Leakage prevention reduces the loss of refrigerant, economizes on resources.
