Embodiment approach

[0050] The torsion outer ring 1 is ring-shaped, and the front end of the inner wall of the torsion outer ring 1 is provided with a first protruding ring 11 and a second protruding ring 12 in sequence from front to back, and an annular cavity 13 is also formed inside the torsion outer ring 1 , the annular chamber 13 is evenly distributed in the circumferential direction along the front and rear direction with a perforated baffle 13a, the perforated baffle 13a is provided with a baffle through hole, and the annular chamber 13 is evenly distributed circumferentially along the rear half There are radial insertion holes 14 corresponding to the baffle through holes of the perforated baffle 13a one by one, and an inner ring 14a of the insertion hole is formed at the connection between the radial insertion hole 14 and the annular chamber 13;

[0051] Further, the outer circumference of the torsion outer ring 1 is formed into a hexagonal shape.

[0052] Thanks to the improvement above,...

Abstract

The invention relates to a gas meter anti-disassembly joint, which includes a torsion outer ring for bearing torsional force, an internal thread ring for screwing with the thread head of the gas meter, and a switch for adjusting the unidirectional rotation direction of the internal thread ring. To the device, the gasket to maintain the seal, the tower joint to connect with the gas hose. In the anti-disassembly joint of the gas meter and its use method described in the present invention, under normal conditions, the twisted outer ring can only drive the inner threaded ring to rotate in one direction and then be screwed on the threaded head of the gas meter to prevent the user from The phenomenon of dismantling and replacing the gas meter without authorization occurs; in an emergency, professional construction personnel can dismantle it, and then perform professional inspection and maintenance operations on the gas meter; the telescopic stroke of the telescopic sleeve can also be adjusted.

Description

technical field [0001] The invention relates to the technical field of gas meters, in particular to a gas meter tamper-resistant joint and a method for using the same. Background technique [0002] With the improvement of people's living standards, many families use piped gas. When the piped gas enters the user's home, it is generally necessary to install an on-off valve and a gas meter. The inlet end of the on-off valve is used to connect with the main pipeline. The meter is connected to the gas outlet of the switch valve through a connecting pipe. At present, the connecting pipe generally includes an elbow, and both ends of the elbow are rotatable and connected with nuts. Through the internal thread on the nut, the two ends of the elbow can be connected Tighten them on the gas outlet of the on-off valve and the gas inlet of the gas meter respectively. Since the usual nuts can be disassembled at will with a universal wrench, people will disassemble and install the gas meter...
