Embodiment Construction

[0015] In the following, the present invention will be further explained based on the embodiments and the accompanying drawings.

[0016] figure 1 The shown anti-theft and anti-disassembly gas meter bellows joint includes a bellows 1, a connecting pipe 2, a nut sleeve 3, a circlip ring 4, a sealing gasket 5, a housing 6 and a flat gasket 7. The housing 6 is attached image 3 As shown, the outer wall is provided with a hexagonal side, which is convenient for screwing operation. The inner cavity of the housing 6 is a stepped hole, and the inner wall of the large diameter hole is provided with image 3 The bevel ring groove shown is 6.2. The nut cover 3 is as attached Figure 5 As shown, its outer circle is in clearance fit with the inner cavity of the housing 6, and the left end of the outer circle corresponds to the hypotenuse ring groove 6.2 of the housing 6 with the following Figure 5 As shown in the rectangular ring groove 3.2, the inner cavity of the nut sleeve 3 is a threade...

Abstract

The invention discloses an antitheft and anti-demolition diaphragm gas meter corrugated pipe connector, which comprises a corrugated pipe, a connecting pipe, 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 connecting pipe 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 connecting pipe are parallel with each other. The connecting pipe 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 assembly, 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 related to the daily necessities of every family-gas fuel, as a commodity, has entered the homes of ordinary people through pipelines. Gas fuels such as natural gas, city gas, and liquefied petroleum gas are clean energy sources, which have the characteristics of good flammability, high calorific value, low pollution emissions, and convenient use, and are accepted by the public. Gas fuel not only facilitates people's lives, but also plays a beneficial role in purifying urban air. Nevertheless, the safe use of gas fuel is an important issue that cannot be ignored. The main components of gaseous fuels are carbon monoxide, hydrogen, methane and ethane, which are highly toxic and flammable, and a slight leaka...
