Description

Novel socket connection device of metal-clad hose

Technical Field

The utility model relates to a connecting device, more specifically say a bit, relate to a novel metal cladding hose's socket connecting device, belong to cooking utensils, hose field.

Background

At present, the main types of hoses connected with gas cookers are three: stainless steel corrugated hose, rubber hose or composite rubber hose, and rubber hose or composite rubber hose with metal protective layer, also called metal-clad hose, wherein the stainless steel corrugated hose is suitable for fixedly mounting gas cooker and other gas appliances; the rubber tube and the composite rubber tube are mainly used for fixedly and non-fixedly mounted gas cookers; the metal-clad hose is suitable for fixed and non-fixed mounting of gas cookers and other gas appliances.

Compared with a general rubber tube and a composite rubber tube, the metal-coated hose has the advantages that the overall strength and the damage resistance of the hose are improved, and the occurrence of gas leakage accidents caused by rat bite can be avoided, the stainless steel corrugated hose has very high pipe body strength, large flow, corrosion resistance, long service life, low possibility of aging and rat bite prevention, the gas industry is greatly popularized and used in recent years, but the product has a defect that the fatigue life of bending and twisting is short, so that the domestic standard and specification clearly indicate that the stainless steel corrugated hose can only be used for fixedly-mounted gas appliances, the connection of the gas appliances is only limited to embedded gas appliances, a large number of household gas appliances are common table appliances, the gas appliances can be frequently moved in the use and maintenance process by people, the requirements on the hose are relatively higher, and most of the domestic gas appliances are still the traditional socket connection mode at present, especially, the common table stove, the rubber tube and compound rubber tube basically adopt the clamp of the larynx hoop to press from both sides and tightly consolidate, it is very convenient and practical, but the metal cladding hose because of having the metal protective layer, it is unsatisfactory to directly use the clamp of the larynx hoop to press from both sides the effect, the tight degree of clamp can not meet the demands, if adopt the stainless steel corrugated hose commonly used to screw up through the screw thread, make the rubber sleeve inside extrude axially, produce inward shrink deformation, compress tightly and reach sealed and fixed with the hose nipple, because the common table stove often moves, the hose nipple and rubber sleeve in the threaded connection piece can produce certain swing, especially under the condition that the hose nipple is nonstandard, the overall dimension is too small, the joint is easy to leak and even drop, so the ideal connection mode of the metal cladding hose is still the clamp.

Chinese patent ZL201520418795.8, which has some problems, such as: because three layers of materials of the metal-coated hose are not axially fixed, when the hose is installed, the gas hose is easy to axially displace and retract backwards, so that the potential safety hazard is caused due to the fact that the hose is not installed in place; in addition, similar products exist in the market, but the protective sleeve of the plastic protective sleeve away from the port part is not removed, the hose clamp directly fastens the connecting sleeve and the three layers of materials of the metal-coated hose to the hose joint, and the tensile strength is greatly influenced due to the three layers of soft plastic layers in the middle, so that the hose joint is easy to fall off when being pulled by external force.
