Abstract
The utility model relates to a sealing structure of a static sounding electrical measuring probe. The sealing structure comprises a probe rod connector and a probe body and is characterized in that an intermediate connector is arranged between the probe prod connector and the connector body; stepped jointing parts are arranged on the outer sides of the intermediate connector and the probe body; a connecting thread is formed on one step; an O-shaped sealing ring is arranged on another step; the intermediate connector is in threaded connection with the inner side of the probe rod connector; an internal thread and a circular bead are arranged on the inner side of the end of the intermediate connector; a rubber sealing plug sleeved on a probe body cable is supported on the circular bead; and a fastening threaded sleeve which is provided with a cable via a hole and is abutted against the rubber sealing plug is arranged on the internal thread. The sealing structure disclosed by the utility model has the advantages that the structure is simple; and the problem of water resistance and sealing of a probe body with the projection area of a conical tip being 10cm<2> can be effectively solved.
Description
Technical field
The utility model belongs to static sounding probe, particularly relates to a kind of hermetically-sealed construction of static sounding electrical measurement probe.
Background technology
In the prior art, static sounding electrical measurement probe is threaded with the probe body by probing rod joint and constitutes, and the probe body can be single bridge probe or doube bridge probe.The tail end of probe body is provided with the plug connector and the cable thereof of the output analog quantity signal of telecommunication that is arranged in probing rod joint.Between probing rod joint that is threaded and the probe body a plurality of O-ring seals are set, anti-sealing or mud get into probing rod joint and etch plug connector even probe body.
It is 10cm that hermetically-sealed construction form existence between the probing rod joint of above-mentioned static sounding electrical measurement probe and the probe body is not suitable for the sharp projected area of awl
2To be probing rod joint be provided with described hermetically-sealed construction with the space of popping one's head between the body is limited and inconvenient for the defective of probe body, its reason.Therefore using the sharp projected area of awl to be 10cm
2The probe body carry out can only taking in the feeler inspection operation adhesive plaster for example to swathe the simple measures of probe body cable, its sealing effectiveness is very unreliable.
The utility model content
The utility model is not to be suitable for for the probing rod joint that solves existing static sounding electrical measurement probe and hermetically-sealed construction form between the probe body exist that to bore sharp projected area be 10cm
2Or 15cm
2The technical problem of probe body, and the hermetically-sealed construction that a kind of static sounding electrical measurement is popped one's head in is proposed.
The utility model is taked following technical scheme for realizing above-mentioned purpose: this electrical measurement probe hermetically-sealed construction comprises probing rod joint and probe body; Characteristic is, is provided with transition joint between probing rod joint and the probe body, and said transition joint is provided with stair-stepping convergence part with the probe body outside; Wherein a ladder is provided with connecting thread; Another ladder is provided with ' O ' RunddichtringO, and said transition joint is connected with the inside thread of probing rod joint, and this end inboard of transition joint is provided with internal thread and shoulder; Said shoulder is supported with the rubber seal plug that is set in probe body cable, and said internal thread is provided with the tightening swivel nut that compresses rubber seal plug of tape cable via hole.
The utility model changes can take following technical measures:
' O ' RunddichtringO of said transition joint and one stepped convergence part, the probe body outside is arranged at the annular groove of probe body surface.
Said rubber seal plug both sides are provided with packing ring.
The beneficial effect and the advantage of the utility model are: this electrical measurement probe hermetically-sealed construction is by cable and the rubber seal plug between the plug connector and tightening swivel nut two parts formation of ' O ' RunddichtringO and transition joint and probe body between transition joint and probe body one end; Distortion takes place and wraps the cable of body of popping one's head in tightly in rubber seal plug under the clamp screw cover effect of precession, thereby can avoid water or mud to get into transition joint and etch plug connector and electrical measurement probe effectively.The utlity model has simple in structure, can solve effectively the awl sharp projected area be 10cm
2The outstanding advantage of probe body waterproof sealing problem.
Description of drawings
Accompanying drawing 1 is the example structure partial cutaway schematic.
Mark among the figure: 1 probe body, 2 transition joints, 2-1 connecting thread, 3 plug connectors, 4 cables, 5 probing rod joints, 6 rubber seal plugs, 7 tightening swivel nuts, 8 packing rings, 9 ' O ' RunddichtringO.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in the figure; Be provided with transition joint 2 between probing rod joint 5 and the probe body 1; Transition joint 2 is provided with stair-stepping convergence part with probe body 1 outside, and wherein a ladder is provided with connecting thread 2-1, and another ladder is provided with and is arranged at probe body 1 surperficial annular groove ' O ' RunddichtringO 9.
Claims (3)
1. the hermetically-sealed construction of static sounding electrical measurement probe; Comprise probing rod joint and probe body, it is characterized in that: be provided with transition joint between probing rod joint and the probe body, said transition joint is provided with stair-stepping convergence part with the probe body outside; Wherein a ladder is provided with connecting thread; Another ladder is provided with ' O ' RunddichtringO, and said transition joint is connected with the inside thread of probing rod joint, and this end inboard of transition joint is provided with internal thread and shoulder; Said shoulder is supported with the rubber seal plug that is set in probe body cable, and said internal thread is provided with the tightening swivel nut that compresses rubber seal plug of tape cable via hole.
