Abstract
The utility model discloses a pressure-maintaining sealing structure for an automotive air conditioner. The pressure-maintaining sealing structure comprises an air conditioner connector, sealing rubber and a plug, wherein the sealing rubber is inserted in the air conditioner connector and is tightened and sealed by the plug; the sealing rubber is provided with a conical surface in close contact with the chamfer of the air conditioner connector and is also provided with a chamfer. The pressure-maintaining sealing structure has the benefits simple structure, low cost, more convenience for assembly and disassembly and higher reliability in sealing.
Description
Technical field
The utility model relates to a kind of motorcar air conditioner pressurize sealing configuration.
Background technique
The pipelines of automobile air conditioner leak detection is one link necessary in production process, normally inject the nitrogen of 3 kilograms of pressure at the air-conditioning jointing, seal test up for safekeeping through caulking gum, plug are fastening, in prior art, its sectional shape of caulking gum is the T font, assembling is inconvenient, it is unreliable to seal, and dismounting is inconvenient, needs at least the moment of torsion of 15kNm can realize that it is the pressure of 3 kilograms that nitrogen is sealed up for safekeeping.
The model utility content
The utility model has proposed a kind of motorcar air conditioner pressurize sealing configuration in order to overcome above-mentioned deficiency, and the caulking gum shape is improved, and only needs the moment of torsion of 5kNm just can realize that it is the pressure of 3 kilograms that nitrogen is sealed up for safekeeping.
The technical solution of the utility model is:
A kind of motorcar air conditioner pressurize sealing configuration comprises: air conditioner interface, caulking gum, plug, and caulking gum inserts the air conditioner interface and tightens sealing by plug, and described caulking gum is provided with the conical surface that carries out close contact with air conditioner interface chamfering.
Described caulking gum also is provided with chamfering.
The utlity model has simple in structure, cost is low, Assembly And Disassembly is more convenient, the sealing more reliable beneficial effect.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in Figure 1, a kind of motorcar air conditioner pressurize sealing configuration comprises: air conditioner interface 1, caulking gum, plug 3, and caulking gum inserts air conditioner interface 1 and tightens sealing by plug 3, and caulking gum is provided with the conical surface 22 that seals with air conditioner interface 1 chamfering.
Caulking gum also is provided with chamfering 21.
Constantly tighten in the process of air conditioner interface 1 at plug 3, the nitrogen that caulking gum can bear is sealed pressure up for safekeeping and is also being increased gradually, only needs the torsion of 5kNm just can realize that it is the pressure of 3 kilograms that nitrogen is sealed up for safekeeping.
The profile of plug 3 can be hexagon or quadrangle, is convenient to tool holder and is screwed into air conditioner interface 1.
