Embodiment
In order to make the object of pressure early warning sealing cap of the present utility model and air conditioner, technological scheme and advantage clearly understand, below in conjunction with concrete drawings and the specific embodiments, the utility model is further elaborated.
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
See Fig. 1 to Fig. 3, the utility model provides a kind of pressure early warning sealing cap, and it comprises cap seat 100, elastic telescopic circle 200, retainer ring 300 and Gask-O-Seal 400.As shown in Figure 1, cap seat 100 is shapes of hollow, and the inside of cap seat 100 is provided with the cavity of through whole cap seat 100, and elastic telescopic circle 200, retainer ring 300 and Gask-O-Seal 400 are installed in cavity.Wherein retainer ring 300 is arranged on the below of elastic telescopic circle 200, Gask-O-Seal 400 is arranged on the below of retainer ring 300, the position of the below of retainer ring is on the sidewalls of the cavities provided with internal thread, and pressure early warning sealing cap of the present utility model can be fixed on the pipe joint of the equipment such as vaporizer, condenser by this internal thread.
Wherein, see Fig. 3, the edge of the elastic telescopic circle 200 in the present embodiment is that embedding and injection molding is in cap seat 100, that is the elastic telescopic circle in the present embodiment adopts embedding and injection molding technique to be embedded in cap seat 100, be sealed-for-life thus between elastic telescopic circle 200 and cap seat 100, there will not be the problem of seal failure, greatly improve the sealing effect of pressure early warning sealing cap like this.Due between elastic telescopic circle and cap seat for sealed-for-life, therefore elastic telescopic circle and retainer ring are without the need to interference fit, elastic telescopic circle does not need retainer ring to compress, and which reduces the fit dimension requirement of elastic telescopic circle and retainer ring, reduces its processing request.
Preferably, as a kind of embodiment, see Fig. 4, cavity in cap seat 100 in the utility model comprises first paragraph cavity 101 and second segment cavity 102, from the orientation shown in Fig. 4, second segment cavity 102 is in the below of first paragraph cavity 101, and the diameter of second segment cavity 102 is obviously greater than the diameter of first paragraph cavity 101.See Fig. 3 and Fig. 5, accordingly, the elastic telescopic circle 200 in the present embodiment comprises the extension 210 being arranged in first paragraph cavity 101 and the base 220 be positioned at below extension 210, and the came of base 220 is injection-moulded in cap seat 100.Elastic telescopic circle in the present embodiment can and the telescopic variation that carry out in various degree different according to the gas pressure in part second cavity below elastic telescopic circle, and the extension 210 of elastic telescopic circle 200 can stretch out cavity or be arranged in cavity along with the flexible of elastic telescopic circle.It should be noted that, the pressure early warning sealing cap in the present embodiment does not need to arrange pressure show needle.The extension given in this enforcement can ensure the sealing of elastic telescopic circle on the one hand, and extension can play the effect of pressure show needle in the past on the other hand, can judge the magnitude relationship of internal pressure and ambient pressure according to the position of extension; Moreover the extension be arranged in first paragraph cavity can also ensure the telescopic direction of elastic telescopic circle, thus ensure its stability used.Elastic telescopic circle in the utility model is formed in one structure, and extension and base are connected as a single entity, and have fundamentally stopped the hidden danger that pressure show needle in the past comes off, have decreased the assembly process of pressure show needle simultaneously.
It should be noted that, pressure early warning sealing cap in the utility model can comprise pressure show needle, now elastic telescopic circle can not comprise extension, now pressure show needle to be arranged on elastic telescopic circle and pressure show needle can move up and down along with elastic telescopic circle thus be positioned at cavity or stretch out cavity, and operator can according to the size of the position judgment internal pressure of pressure show needle and ambient pressure.General, illustrate that when pressure show needle stretches out pressure early warning sealing cap internal pressure is greater than ambient pressure.Best pressure show needle is positioned on the center line of first paragraph cavity of cavity.
Further, see Fig. 3, Spielpassung between the inwall (i.e. the wall of first paragraph cavity 101) of extension 210 and cap seat 100.Moving up and down of extension can be facilitated like this.
More excellent, see Fig. 5, the base 220 in the present embodiment comprises the central part 221 be connected with extension 210 and the extension part 222 being positioned at central part outer circumferential side, and extension part 222 embedding and injection molding is in cap seat 100, and central part 221 is arranged in cavity.Central part 221 in the present embodiment, the center line of extension 210 overlap with the center line of first paragraph cavity.Such setting can ensure the steadily flexible of base 220, thus ensures the stability of pressure display result.
Further, see Fig. 5, described central part 221 is also provided with bump 223 away from the first surface of described extension 210, the surface of described bump 223 and the first surface of described central part 221 seamlessly transit.Arranging bump can make the pressure in the better reaction cavity of elastic telescopic circle change, and makes whole pressure early warning sealing cap sensitiveer.
More excellent, see Fig. 5, described bump 223 is provided with depressed part 224, on the center line being centrally located at described cavity of described depressed part 224.Arranging depressed part 224 can avoid the excessive impact force to elastic telescopic circle of internal pressure excessive, can increase the lifting surface area of whole base after arranging depressed part.Wherein, depressed part 224 can be various shape, is preferably hemisphere.
Preferably, as another kind of embodiment, the second surface be connected with described extension 210 of described central part 221 is provided with annular groove 225 around described extension 210.Annular groove is set and can makes the flexible more flexible of extension.
It should be noted that, the elastic telescopic circle in the present embodiment is integrated herein.
Cap seat in the utility model can be one-body molded, also can split arrange.Preferably, as a kind of embodiment, see Fig. 4, the cap seat 100 in the present embodiment comprises interconnective upper cap seat 110 and lower cap seat 120, the edge of elastic telescopic circle 200 can molding and forming on upper cap seat 110, also can molding and forming on lower cap seat 120.Cap seat 100 split is arranged and can facilitate the shaping of elastic telescopic circle.For interference fit can better protect elastic telescopic circle between upper cap seat 110 and lower cap seat 120, better air pressure detection effect can be reached simultaneously.
