Abstract
The utility model relates to an inserting opening type metallic corrugated flexible tube for fuel gas. Most of presently used tower-shaped flexible pipe joints have big errors compared with the standard requirements. The exiting flexible pipe is easy generate the phenomenon that the exiting flexible pipe can not be inserted in the tower-shaped flexible pipe joint, or the exiting flexible pipe can not be tightly pressed after inserted in the tower-shaped flexible pipe joint. Therefore, the fuel gas can be easily leaked. The utility model comprises a metallic corrugated section and contracting necks, wherein the contracting necks which are positioned at both ends of the corrugated section are connected with the corrugated section into one body. The utility model is characterized in that each of the contracting necks is sheathed with a connecting piece; the connecting piece is in threaded connection with a nut; a rubber sleeve which is positioned in the nut is arranged between the connecting piece and the nut, wherein an inner conical surface is arranged at the bottom part of the nut. A conical surface which is arranged on the lateral surface of the rubber sleeve is matched with the inner conical surface on the nut. The utility model is convenient for the insertion of the tower-shaped flexible pipe joint, and is particularly suitable for the connection with the tower-shaped flexible pipe joint, the shape and the size of which have big errors compared with the standard value. Therefore, the leakage of the fuel gas is prevented.
Description
Technical field
The utility model is the faucet type metal bellow that a kind of combustion gas is used.
Background technique
Combustion gas 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 metal (being generally stainless steel) corrugated flexible hose.Sealing problem when being connected with source of the gas delivery outlet and kitchen range suction port for solving pagoda shape hose coupling, the patent No. is that the Chinese patent of 200420021364.X discloses a kind of integrated type metal bellow, it is used for and being connected of pagoda T-joint, substitute existing rubber pipe, the structure of metallic hose is as follows: an end of bellows expands neck down again after necking down, expand in the neck rubber sleeve is housed, the outer end of expanding neck is useful on the fixedly riveting mouth of rubber sleeve, in rubber sleeve behind the insertion pagoda shape hose coupling.Rubber sleeve produces deformation, thereby has guaranteed the sealing effect of joint and locking effect radially.Because the faucet type combustion gas of this kind structure has higher requirements with the dimensional accuracy of metallic hose to pagoda shape hose coupling, although GB, rower is to the shape of pagoda shape hose coupling, size has clear and definite requirement, but when as installed, especially when combustion gas old user's rubber pipe is changed metal bellow, find that the existing most of pagoda shape hose couplings and the standard-required error of (production) used is bigger, the hose construction of above-mentioned patent disclosure be easy to generate pagoda shape hose coupling insert not advance or insert after the phenomenon that do not press tightly, combustion gas easily produces leakage, directly injures people's life safety.
The model utility content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, the faucet type metallic hose that a kind of applicability is strong, make things convenient for pagoda shape hose coupling to insert is provided, be particularly suitable for and being connected of the bigger turriform hose coupling of shape, size and reference value error, to improve the sealing of joint, the Security when further strengthening using.
For this reason, the utility model adopts following technological scheme: faucet type combustion gas metallic hose, the necking down that comprises the wavy metal section, is positioned at the bellows segment two ends and is connected as a single entity with it, it is characterized in that being with in the necking down a connection piece, the nut that is spirally connected on the link has a rubber sleeve that is positioned at nut between link and nut, the nut bottom is provided with an inner conical surface, the side of rubber sleeve is provided with a conical surface, and it cooperates with inner conical surface on the nut.When the utility model uses, earlier pagoda shape hose coupling is inserted in the rubber sleeve, fastening nut then, deform until rubber sleeve, because the conical surface of nut is conflicted on the conical surface of rubber sleeve, the jail is supported in necking outer end, the another side of rubber sleeve, the axial expansion of rubber sleeve is stretched to be restricted, it can only make radial deformation, thereby rubber sleeve is pressed on the pagoda shape hose coupling, play good sealing effect, be specially adapted to the insertion of the bigger turriform hose coupling of shape, size and reference value error.
Described faucet type combustion gas metallic hose, there is an inner conical surface outer end of link, the place, outer end of necking down is provided with the horn mouth that cooperates with inner conical surface, the rubber sleeve side that cooperates with horn mouth is a conical surface, the longitudinal cross-section of rubber sleeve is trapezoidal like this, the good sealing effect that the conical surface and cone match cooperate with the plane than the plane.
Described faucet type combustion gas metallic hose, place, the outer end of necking down is provided with a positioning ring that is positioned at the link outside, and the rubber sleeve side that cooperates with positioning ring is a plane, and this be the structure that another kind of necking down outer end is located, and the employing plane cooperates with the plane.
The utility model is by the be spirally connected length of adjusting nut on link, thereby change the degree of adaptability of rubber sleeve and pagoda shape hose coupling, has following beneficial effect: make things convenient for pagoda shape hose coupling to insert, be particularly suitable for and being connected of the bigger turriform hose coupling of shape, size and reference value error, the amount of deformation of regulating rubber sleeve by fastening nut guarantees the reliable sealing of joint, prevented the leakage of combustion gas, the Security when further having strengthened using.
Below in conjunction with drawings and Examples the utility model is further described.

Embodiment
Faucet type combustion gas metallic hose as shown in Figure 1, 2, two necking downs 2 that comprise wavy metal section 1, are positioned at the bellows segment two ends and are connected as a single entity with it.Be with a connection piece 3 respectively in two necking downs, the nut 4 that is spirally connected on the link 3,4 on link 3 and nut have a rubber sleeve 5 that is positioned at nut, and nut 4 bottoms are provided with an inner conical surface, and the side of rubber sleeve 5 is provided with a conical surface, and it cooperates with inner conical surface on the nut; There is an inner conical surface outer end of link 3, and the outer end of necking down is provided with the horn mouth 6 that cooperates with inner conical surface, and rubber sleeve 5 sides that cooperate with horn mouth 6 are a conical surface, thereby makes the longitudinal cross-section of rubber sleeve 5 be trapezoidal.
During use, earlier pagoda shape hose coupling is inserted in the rubber sleeve, because this moment, nut was not tightened, rubber sleeve is not squeezed and in a state of nature, joint is easy to insert in the rubber sleeve, and fastening nut then is because the conical surface and the bell-mouthed conical surface of nut push rubber sleeve simultaneously, make rubber sleeve can only make radial deformation, thereby rubber sleeve is pressed on the pagoda shape hose coupling.
As shown in Figure 3, be with embodiment 1 difference: place, the outer end of necking down is provided with a positioning ring 7 that is positioned at the link outside, rather than horn mouth 6, rubber sleeve 5 sides that cooperate with positioning ring 7 are a plane, this is the structure at another kind of necking down outer end place, and positioning ring 7 and rubber sleeve 5 employing planes cooperate with the plane.
