Quick-assembly protective sleeve structure of drilling tool

Abstract

The invention relates to a quick-assembly protective sleeve structure of a drilling tool. The quick-assembly protective sleeve structure comprises a protective ring, wherein a plurality of protective pieces are arranged in the circumferential direction of the protective ring in a spaced manner; a tapered protective cavity is integrally formed among the protective pieces; the drilling tool is arranged in the protective cavity; the protective pieces comprise wrapping pieces for wrapping the drilling tool, and swinging pieces arranged in the protective ring; the swinging pieces and the wrapping pieces are integrally formed; connection and bending parts between the swinging pieces and the wrapping pieces are rotationally mounted on the protective ring; a regulating sleeve is arranged in the center of a zone defined by the swinging pieces; a connecting rod is connected between the regulating sleeve and one swinging piece correspondingly; one end of one connecting rod is fixedly connected with one swinging piece correspondingly; the other ends of the connecting rods are hinged to the side wall of the regulating sleeve; a fixing plate is mounted at one side of the axial direction of the protective ring, and is fixedly connected with the protective ring through fixing rods; a spiral short column is rotationally mounted in the center of the fixing plate; the inner end of the spiral short column is spirally mounted in the regulating sleeve; an operating panel is mounted at the outer end of the spiral short column; and a handle is mounted at the side surface of the operating panel.

Description

technical field [0001] The invention relates to a protective sleeve of a drilling tool for geological exploration. Background technique [0002] In order to prevent damage to the thread at the end of the drilling tool, it is generally necessary to install a protective sleeve on the threaded end. The existing protective sleeve and the drilling tool are spirally installed, and both the installation operation and the removal operation are relatively laborious, and the number of times of repeated use is relatively small, so the cost is also relatively high. On the same day, the applicant applied for a patent titled "Quick Mounting Protective Cover for Drilling Tools", which can be quickly installed on the drilling tool and quickly removed, and is easy to use; however, in the above patent, the operating wheel used extends out The end face of the protective sleeve leads to a large axial distance of the protective sleeve, which affects the spatial arrangement to a certain extent. ...
