It is rotationally connected with lid 410.Containment vessel 400 has the effect of protection, it is ensured that the safety of the most whole device, no
Fragile, increase service life.The through hole 411 passed for wire it is provided with on lid 410.
Further, containment vessel 400 also has the effect of the rotational angle limiting connecting rod 200, the top of connecting rod 200
240 are set to spherical, and connecting rod 200 is rotationally connected with lid 410 by spherical end, and connecting rod 200 is relative to lid 410
Rotation flexible.Referring to Fig. 8, in actual use, when by External Force Acting, there is certain inclining in containment vessel 400
Tiltedly, simultaneously as conduction gravitation ball 100, connecting rod 200 and the action of gravity of holding shell 300, connecting rod 200 drives holding shell
300 occur together corresponding tilt, after holding shell 300 tilts, conduction gravitation ball 100 is positioned at the bottom of shell 310 under gravity
Center, conduction gravitation ball 100 will not be directly scrolled to trigger the position of intelligent control unit, i.e. the angle of this inclination is safety
Angle, i.e. in this slant range, conduction gravitation ball 100 will not trigger intelligent control unit, uses more flexible, it is to avoid mistake
Operate and the situation of fuel gas pipeline blocking-up of setting out.When containment vessel 400 continues to tilt, now, containment vessel 400 limits connecting rod
The rotation of 200, i.e. connecting rod 200 rotate not with respect to containment vessel 400, and now, conduction gravitation ball 100 is at the first sphere rail 311
Interior rolling, conduction gravitation ball 100 connects the first conductive part and the second conductive part, and intelligent control unit turns on, and plays blocking-up combustion gas
The effect of pipeline, it is therefore prevented that combustion gas fractures due to pipeline or ruptures and reveal, and adds safety.
Referring to Fig. 7, containment vessel 400 limits the various structures of the rotational angle of connecting rod 200, the preferred side of this embodiment
In case, housing 420 is in tubular, and housing 420 includes that cross section is annular perisporium 421 and includes diapire 422, and diapire 422 is pacified
Being loaded on the bottom of perisporium 421, lid 410 is installed on the top of perisporium 421, when connecting rod 200 rotates relative to lid 410, holds
Shell 300 of receiving can be pushed against on perisporium 421, when holding shell 300 rotates, have between holding shell 300 and perisporium 421 certain between
Every, this interval is safe distance, and the rotation occurred at this interval inside connecting rod 200 is security standpoint, will not trigger intelligence
Control unit, uses more safe and reliable.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
