Abstract

The invention discloses an antitheft and anti-demolition diaphragm gas meter corrugated pipe connector, which comprises a corrugated pipe, a connector, a nut sleeve, a snap spring ring, a sealing gasket, a shell and a flat gasket. The inner cavity of the shell is provided with the nut sleeve, an annular groove and the snap spring ring for axial limitation are arranged between the inner cavity of the shell and the nut sleeve, and the joint end faces of the inner cavity of the shell and the nut sleeve are provided with wedge slots so as to form a screwing linkage structure. The pipe connector forms a bearing structure through the cooperation between an outer ring sleeve and steel balls and a pipe sleeve, and the left and right end faces of the pipe connector are parallel with each other. The pipe connector is arranged in an inner hole of the nut sleeve, the left pipe wall is sleeved with the sealing gasket, and the right pipe orifice exposed from the shell is in seal connection with the corrugated pipe. With the formed a self-locking structure, the corrugated pipe connector can only be screwed in one direction to be installed and can prevent free detachment except for destructive detachment. The self-locking structure prevents privately detachment to a maximum degree, effectively avoids leakage and gas steal, and provides effective technical guarantee of public security.

Description

technical field [0001] The invention relates to a pipe connection joint, in particular to a gas hose joint with an anti-disassembly structure. Background technique [0002] With the progress of society, people's living conditions have been greatly improved, especially when it comes to the daily necessities of every household - gas fuel, which has entered the homes of ordinary people through pipelines as a commodity. Gas fuels such as natural gas, city gas, and liquefied petroleum gas are clean energy, which are accepted by the public because of their good flammability, high calorific value, low pollution emissions, and convenient use. Gas fuel not only facilitates people's life, but also plays a beneficial role in purifying urban air. Nonetheless, the safe use of gaseous fuels is an important issue that cannot be ignored. The main components of gaseous fuel are carbon monoxide, hydrogen, methane and ethane, which are highly toxic and flammable, and a slight leakage may cau...
