The purpose of this utility model is to provide a kind of tidal level instrument code-disc anticreep/bridle wire apparatus, has solved the easy take off/wire jumper that occurs of existing tidal level instrument and has caused measuring the even technical matters of instrument damage of out of true.
For reaching, solve above-mentioned technical purpose, the utility model proposes a kind of tidal level instrument code-disc anticreep/bridle wire apparatus, on code-disc, be provided with the steel wire winding groove that holds steel wire, anticreep/bridle wire apparatus comprises rotating roller, rotating roller is positioned at the sidepiece of code-disc, steel wire is limited in steel wire winding groove, prevents that steel wire from take off/jumping out from steel wire winding groove.Rotating roller can be followed the rotation of code-disc and be rotated.
Preferably, rotating roller is arranged on tidal level instrument by installing mechanism.
Further, installing mechanism comprises holder, support bar and resetting means, and described holder is installed on tidal level instrument, and one end of support bar and holder join and can rotate around holder, the other end and the rotating roller of support bar are joined, and between holder and support bar, are provided with resetting means.During use, rotating roller is limited in steel wire in steel wire winding groove under the effect of resetting means, and in other cases, can pull support bar, thereby rotating roller and code-disc are departed from.
Preferably, resetting means is torsion spring.
Preferably, described rotating roller is joined by bearing and support bar.
In order to guarantee the serviceable life of rotating roller, code-disc and steel wire, rotating roller is preferably abrasive rubber material.
Design based on above-mentioned tidal level instrument code-disc anticreep/bridle wire apparatus, the utility model has also proposed a kind of tidal level instrument, tidal level instrument comprises float end code-disc and weight end code-disc, tidal level instrument also comprises anticreep/bridle wire apparatus, anticreep/bridle wire apparatus comprises rotating roller, rotating roller is positioned at the sidepiece of code-disc, and steel wire is limited in steel wire winding groove, prevents that steel wire from take off/jumping out from steel wire winding groove.
The beneficial effects of the utility model are: the utility model is limited in steel wire in steel wire winding groove by rotating roller, can effectively prevent that steel wire from take off/jumping out in steel wire winding groove.Rotating roller is arranged on holder by support bar, between holder and support bar, be provided with resetting means, thereby rotating roller is limited in steel wire in steel wire winding groove, simultaneously under the effect of resetting means, also can pull support bar, rotating roller and code-disc are departed from, unclamp after support bar, under the effect of resetting means, rotating roller resets, and can realize steel wire is limited in to the effect in steel wire winding groove again.Due to rotating roller, can follow the rotation of code-disc and rotate, can't hinder the folding and unfolding of steel wire.Thereby the utility model has at utmost guaranteed the measuring accuracy of tidal level instrument, and simple in structure, easy accessibility, practical.
Accompanying drawing explanation
