Description

Dead weight type ground resistance value probe

Technical Field

The utility model belongs to the technical field of ground/terrace resistance test technique and specifically relates to dead weight formula ground resistance value probe.

Background

The Chinese patent discloses a leakage resistance testing device for a working terrace/platform, which is patent No. 200620111277.2 and comprises a measuring meter, a lead and a testing electrode. Generally speaking, this kind of test electrode is the probe that the shape is similar to the weight, and its level lower terminal surface does benefit to and contacts with ground, but still exists not enoughly, (1) the weight of probe self is not enough, and at the terrace of unevenness, the lower terminal surface of probe can't contact with the terrace completely, influences the effect of test, still takes place to sideslip easily on the terrace that has the slope, influences the test, (2) the manual work snatchs and need bow or squat down, the not quick travel of being convenient for.

Disclosure of Invention

Not enough to prior art, the utility model provides a lower terminal surface can contact completely with the terrace, is difficult to take place to sideslip, and is convenient for the dead weight formula ground resistance value probe that removes.

The technical scheme of the utility model is that: dead weight formula ground resistance value probe, its characterized in that: the probe comprises a probe body and a metal shell, wherein the probe body is a cylinder, the metal shell is a cylinder, the middle part of the metal shell is provided with a groove matched with the shape and size of the probe body, the probe body is inserted into the groove and fixed through a bolt, and the bottom end of the probe body is exposed outside the groove.

Further, the telescopic link is detachably installed at metal casing's top, the top of telescopic link is provided with the handle, the cover is equipped with the antiskid cover on hand, the material of telescopic link is the aluminum alloy, during the test, can pull up the telescopic link, and the manual work snatchs the telescopic link and removes the probe when being convenient for the multiple spot test, improves the work efficiency of test, can pack up the telescopic link when accomodating, is convenient for accomodate.

Furthermore, metal casing's bottom is pasted and is had insulating pressure sensitive adhesive gasket, and metal casing will insulate pressure sensitive adhesive gasket compression to the increase takes place to sideslip with the frictional force on ground, thereby prevents that the probe from taking place to sideslip, simultaneously because the bottom surface of probe tape point when the test, insulating pressure sensitive adhesive still plays insulating effect, prevents that metal casing is electrically conductive.

Furthermore, a through hole is formed in the top of the metal shell, a lead is arranged in the through hole in a penetrating mode, one end of the lead stretches into the metal shell and is electrically connected with the probe body, and the other end of the lead stretches out of the metal shell and is electrically connected with the test meter.

Furthermore, the metal shell is made of iron.

Furthermore, the telescopic rod is provided with scale marks, so that the telescopic rod can be transversely placed for distance measurement after being pulled open without a measuring tool.

The utility model discloses a theory of operation and application method:

during the use, the manual work is pulled out the telescopic link, handheld handle, put the probe at the test position, metal casing will insulate pressure sensitive adhesive gasket compression, thereby increase and the frictional force on ground, prevent that the probe from taking place to sideslip, simultaneously because metal casing's weight, push down the probe body, make the lower terminal surface of probe body and detect the terrace and contact completely, a check point detects the back that finishes, handheld handle, with the probe removal to next check point, all detect the back that finishes, reset the telescopic link, accomodate again.

The utility model has the advantages that: the metal shell is sleeved on the periphery of the probe body, so that the function of counterweight can be achieved, the bottom of the probe body can be in complete contact with a detection terrace, and the detection effect is improved; by arranging the telescopic rod, the probe is convenient for workers to move; through setting up insulating pressure sensitive adhesive gasket, can increase the frictional force with ground, prevent that the probe from taking place to sideslip, play insulating effect simultaneously, prevent that metal casing is electrically conductive.
