Problems solved by technology

At present, most of the technologies for preventing illegal disassembly of gas meters are to install lead seals at the lock nuts of the inlet and outlet pipes of gas meters, or to use disposable one-way backstop devices for the lock nuts of the inlet and outlet pipes of gas meters. The form of lead seals is already very backward, and It is easy to be unlocked without trace, and it is difficult to obtain evidence when it is determined whether it is illegally unlocked. The one-way backstop device for one-time use of the lock nut is difficult to disassemble during normal maintenance of the gas meter.
At the same time, it is also easy to be restored by substitutes after illegal disassembly. More importantly, the above methods cannot leave electronic evidence, and cannot automatically lock the electronic metering of the gas meter when it is illegally disassembled.

Embodiment 1

[0051]As shown in Figures 1 to 4, a lock box 1 is arranged between the inlet and outlet pipes of the gas meter, and each of the two end faces of the lock box 1 facing the inlet and outlet pipes of the gas meter has a lock bar on the lock cap 2 3. A gap 17 with a suitable shape and size. The lock cap 2 looks like a bottle cap and is composed of a ring side wall and an upper cover surface. The inner diameter of the ring side wall is appropriately larger than the outer diameter of the lock nut 10 and the side wall It is rigid and continuous. There is a circular hole in the center of the upper cover. The diameter of the hole is appropriately larger than the diameter of the inlet or outlet pipe. The L-shaped protrusion equal to the wall thickness of the lock mother, the position of the L-shaped protrusion on the arc edge is always on the two outer sides of the inlet and outlet pipes, when the two O-shaped lock caps 2 move down along the inlet and outlet pipes to End point, when sur...

Embodiment 2

[0056] As shown in Figures 6 and 7, the lock box is an upside-down box, the lock cap 602 is O-shaped, and extends horizontally along the upper cover of the lock cap 602 to form a plate-shaped lock rod 603. The two Lock bar 603 is connected on the outer surface of lock box 601, and the outer surface of lock box 601 that is connected with lock bar 603 is provided with a hole, and two lock bars 603 are provided with identical hole 606 respectively with this hole correspondence place, when two When the lock bars are docked, the holes 606 of the two lock bars overlap and overlap with the holes on the lock box 601, and a nail cap is inserted in the holes of the lock box 601 and the lock bar 603 to expose a metal nail 607 outside the lock box 601 A sleeve 608 is provided at the position corresponding to the hole in the lock box 601, a hole 609 is provided on the wall of the sleeve, and a horizontal deadbolt 610 is arranged in the lock box 601 corresponding to the hole 609, and the dea...

Embodiment 3

[0060] As shown in Figure 8, when the gas meter is already in use and it is inconvenient to install the O-shaped lock cap, a U-shaped lock cap 802 can be used. The U-shaped lock cap 802 includes a semicircular segment and two natural straight segments to form a rigid continuous The upper cover surface 804 on the side wall and the upper end surface of the semicircle section, the diameter of the semicircular side wall of the U-shaped lock cap 802 is appropriately greater than the diameter of the lock nut, and the center of the upper cover surface 804 has a circular hole whose diameter is equal to the diameter of the inlet pipe or the outlet pipe. The round hole is connected with the cover surface of the straight section with the same diameter and width, and the inner side of the lower end surface of the semicircular side wall still has the same L-shaped protrusion as the O-shaped lock cap in Embodiment 1. The correct position of the L-shaped protrusion in this embodiment It is al...

Abstract

The present invention provides a mechatronics type device for preventing the disassembly of the gas meter. The device includes a lock box, a lock pole which is connected with the lock box and a lock hat which is connected with the lock pole and the lock hat is inserted in the locknut of the inlet and outlet pipe; an integrated circuit chip is provided in the lock box; an IC card reader, and at least one of a USB interface or a needle shaped faucet are provided on the lock box. Or the lock box is inserted in the locknut of the inlet and outlet pipe directly, and an electric magnet or an electric moter that is connected with the integrated circuit chip is provided in the lock box. Said lock hat can be O shaped or U shaped. The mechatronics type device is suitable for every kind of gas meter whether the meter has been used or has just been produced, and the circuit is destroyed leaving the when the lock pole is illegally detached or the lock box gas is stolen, at the same time, the lock box is small and the space is took good advantage of and the production and installation are simple and the cost is low.

Description

technical field [0001] The invention relates to an anti-disassembly device for a gas meter, in particular to an anti-disassembly device with certain mechanical strength, which can prevent illegal disassembly and can leave electronic evidence for illegal disassembly. Background technique [0002] With the widespread use of gas in households, explosion accidents and gas theft caused by unauthorized disassembly and assembly of gas meters have become one of the focuses of the daily management work of the gas management department. Especially as the price of gas energy continues to increase, the primary measure for gas companies to effectively reduce costs and reduce the gap between supply and marketing is to prevent illegal removal of gas meters and stealing gas. At present, most of the technologies for preventing illegal disassembly of gas meters are to install lead seals at the lock nuts of the inlet and outlet pipes of gas meters, or to use disposable one-way backstop devices...
