Adapter of gas stove

Abstract

The invention discloses an adapter of a gas stove. The adapter of the gas stove comprises a first connecting piece, a second connecting piece, a pressure-bearing ring and a sealing sleeve, wherein the first connecting piece comprises a locking nut and a short sleeve; the inner diameter of the locking nut is greater than that of the short sleeve; the second connecting piece has an outer thread tube joint structure and comprises an upper thread tube, a lower thread tube and a hexagon head; a limiting ring table is arranged on the inner peripheral wall of the upper thread tube; and during mounting and using of the adapter of the gas stove, the first connecting piece, the pressure-bearing ring and the sealing sleeve successively sleeve a socket connector of the stove, the second connecting piece is arranged on a locking nut of the first connecting piece in a spinning manner through the upper thread tube, the upper end of the pressure-bearing ring is abutted to the lower end surface of the short sleeve, the lower end of the pressure-bearing ring is pressed to the upper end of the sealing sleeve, and the lower end of the sealing sleeve is pressed on the limiting ring table of the inner peripheral wall of the upper thread tube. The adapter of the gas stove has the advantages of simple structure, low cost, convenience in use, good airtightness, high safety and long service life, and the problem that the gas stove cannot be connected with a metal hose can be solved effectively.

Description

technical field [0001] The invention relates to a connection device, in particular to a conversion joint used for connecting a metal hose to a gas cooker. Background technique [0002] Gas is an essential energy source in people's daily life. At present, the gas cooker used by people cannot be connected with the metal hose because the air inlet socket interface does not have a threaded buckle. Because the soft rubber hose is not resistant to high temperature and is easy to burn, once the gas leaks and catches fire, the soft rubber hose will become the weakest link and be burned quickly, aggravating the gas leakage and the spread of the fire, and the safety is poor. At the same time, the soft rubber hose is often bitten by mice during actual use, which not only affects normal use, but also easily brings safety hazards. In addition, the connection method using soft rubber hose is easy to be disassembled and modified by users due to its relatively simple structure. For gas o...

Problems solved by technology

[0004] In order to solve the problems of combustibility, easy damage and poor safety in the existing technology of using soft rubber tubes to connect gas cookers and gas pipelines, the present invention provides a gas cooker conversion joint, which includes a first connecting piece, a second Two connecting parts, a pressure bearing ring and a sealing sleeve, the first connecting part includes a lock nut and a short sleeve connected together, the lock nut and the short sleeve are coaxial and the inner diameter of the lock nut is larger than the short sleeve The inner diameter of the second connector is an externally threaded pipe joint structure, and includes an upper threaded pipe, a lower threaded pipe and a hexagonal head arranged between the upper threaded pipe and the lower threaded pipe, the inner peripheral wall of the upper threaded pipe A limited ring platform is set up; during installation and use, the first connecting piece, the pressure bearing ring and the sealing sleeve are sequentially set on the socket interface of the cooker, and the second connecting piece is screwed into the lock of the first connecting piece through the upper threaded pipe. On the tight nut, wherein, the upper end of the pressure bearing ring is pressed against the lower end surface of the short casing, the lower end of the pressure bearing ring is pressed against the upper end of the sealing sleeve, and the lower end of the sealing sleeve is pressed on the limit ring platform on the inner peripheral wall of the upper threaded pipe, The lower threaded pipe is used to connect the metal hose
