Abstract
The utility model relates to an integral metal corrugated hose. A rubber tube is usually used for the connection between an outlet of an air source and a connector of an exiting tower-shaped hose. Due to the defects of easy aging, no corrosion resistance and no high-temperature resistance exists in a rubber tube, the service life is short; the accidents caused by gas leakage often happen, which brings serious safety hazard to users. The utility model comprises a metal corrugated hose and diameter-reducing pipes arranged at both ends of the metal corrugated hose. The integral metal corrugated hose is characterized in that an outer end of one diameter-reducing pipe is provided with a diameter-expanding tube; a rubber sleeve is installed in the diameter-expanding tube; the outer end of the diameter-expanding tube is provided with a rivets opening for fixing the rubber sleeve to position the rubber sleeve axially. The outer end of the other diameter-reducing pipe is provided with a bulge loop which is connected into an integrative body; a nut with a bottom hole is sheathed outside the diameter-reducing tube; the diameter of the bottom hole is smaller than the outer diameter of the bulge loop. The rubber sleeve wrapped by the metal corrugated hose is arranged at the connecting point between the integral metal corrugated hose and the connector of the tower-shaped hose. The utility model has the advantages of high-temperature resistance, corrosion resistance, good sealing effect, high safety and long service life.
Description
[technical field]
The utility model is a kind of metal bellow.
[background technique]
Metal (being generally stainless steel) corrugated flexible hose is a kind of connecting tube that combustion gas tool, kitchen range, burner etc. are connected with the source of the gas delivery outlet of being used for.The joint of installing on combustion gas tool, kitchen range, the burner is pagoda shape hose coupling mostly at present, and pagoda shape hose coupling adopts rubber pipe usually with being connected of source of the gas delivery outlet, because defectives such as the rubber pipe existence is easily aging, not corrosion-resistant, non-refractory, working life is short, happen occasionally by gas leakage is accidents caused, bring serious potential safety hazard to the user.
[model utility content]
The technical assignment of technical problem to be solved in the utility model and proposition is to overcome above-mentioned prior art defective, provides a kind of high temperature resistant, corrosion-resistant, and the integrated type metal bellow of good sealing effect to improve Security, increases the service life.
The technical solution of the utility model is such: the integrated type metal bellow, comprise metal bellows and the undergauge that is located at its two ends, the outer end that it is characterized in that a undergauge is provided with hole enlargement, rubber sleeve is housed in the hole enlargement, the outer end of hole enlargement is provided with the riveting mouth that is used for fixing rubber sleeve, and rubber sleeve is played axially locating; The outer end of another undergauge is provided with the bulge loop that is connected as a single entity, and undergauge is with the nut of a band bottom outlet outward, and the diameter of bottom outlet is less than the external diameter of bulge loop, prevents that nut from pulling out from bulge loop.Rubber sleeve is wrapped in the metal body, not cracky, cracking, and the metal body is high temperature resistant, corrosion-resistant, prolonged the working life of connecting tube, insert pagoda shape hose coupling in rubber sleeve after, rubber sleeve produces deformation, thereby guarantees the sealing effect of joint and locking effect radially.
Described integrated type metal bellow, the diameter of bottom outlet be less than the external diameter of bellows, the bellows nut can slippage to the external diameter of bellows, when bellows deformed, nut can not blocked by bellows.
Described integrated type metal bellow, the undergauge place that is positioned at the bulge loop outside is with a rubber pad, further the enhanced leaktightness effect.
Described integrated type metal bellow, the undergauge place that is positioned at the hole enlargement inboard is provided with end steel wire freely, after inserting pagoda shape hose coupling in the rubber sleeve, the free end of steel wire is fixed in the groove of pagoda shape hose coupling, further strengthen the axial restraint effect, prevent that hose coupling from deviating from rubber sleeve.
The utility model is all-in-one-piece metal bellow, structure is different from existing rubber pipe fully, be provided with the rubber sleeve that is wrapped up by metal bellows with the joint of pagoda shape hose coupling, both high temperature resistant, corrosion-resistant, guaranteed good sealing effect again, improve the Security when using, prolonged working life.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[embodiment]
As shown in Figure 1, the integrated type metal bellow, undergauge 2-1,2-2 that it comprises corrugated stainless steel tubing 1 and is located at its two ends, the undergauge 2-1 outer end that is positioned at bellows 1 inboard is provided with hole enlargement 3, the rubber sleeve 4 that cooperates with pagoda shape hose coupling 11 is housed in the hole enlargement 3, and the outer end of hole enlargement 3 is provided with the riveting mouth 5 to 4 axially locating of rubber sleeve; The undergauge 2-2 outer end that is positioned at bellows 1 outside is provided with the bulge loop 6 that is connected as a single entity, and undergauge 2-2 is with the nut 8 of a band bottom outlet 7 outward, and the diameter of bottom outlet 7 is less than the external diameter of bulge loop 6 and bellows 1.The undergauge 2-2 place that is positioned at bulge loop 6 outsides is with a rubber pad 9, strengthens the sealing effect at this place.The undergauge 2-1 place that is positioned at hole enlargement 3 inboards establishes and is embedded with a steel wire 10, and when cooperating with pagoda shape hose coupling 11, the free end of steel wire 10 is embedded in the groove of hose coupling 11, further strengthens the axial restraint effect, prevents that hose coupling 11 from deviating from rubber sleeve 4.
