Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and most preferred embodiment:
A kind of probe apparatus, described probe comprise probe 1 and are connected housing 8, connect the afterbody that housing 8 is located at probe 1, are provided with attaching nut's axle 7 and attaching nut 5 on connection housing 8, and described attaching nut's axle 7 is connected in the outside of probe 1; Be connected with attaching nut 5 outside attaching nut's axle 7, be provided with the space between attaching nut 5 internal thread and the attaching nut's axle 7;
Probe 1 also is connected with adapter, adapter structure be, in the main body 9 of adapter, be provided with the through hole 11 that the aperture is not less than probe 1 external diameter, the two ends of adapter main body 9 are provided with external thread; The attaching nut's 5 of the external thread of an end and probe 1 internal thread correspondence wherein, the thickness of the hole wall that this external thread and through hole 11 constitutes is corresponding with the space between attaching nut's axle 7 with attaching nut 5 internal thread, and probe 1 passes through attaching nut 5 and is connected adapter with this external thread.
The outside surface of described attaching nut's axle 7 is tapers; The inside surface that is connected the through hole 11 of an end on the described adapter with probe 1 is taper; The cone-shaped inner surface correspondence of the conical outer surface of attaching nut's axle 7 and described through hole 11.
Be provided with O-ring seal 3 between the cone-shaped inner surface of the conical outer surface of described attaching nut's axle 7 and described through hole 11.The material of described O-ring seal 3 is a silicon rubber.The cone-shaped inner surface of the conical outer surface of described attaching nut's axle 7 or described through hole 11 is provided with seal groove 2, and described O-ring seal 3 is located in this groove.
