Problems solved by technology

But the defect that it exists is that, when the clamping bar at the front end of the two long measuring handles is in contact with the cable, it cannot ensure that the contact points on both sides and the cable are on the same diameter line of the cable; at the same time, one end of the measuring ruler and the measuring length The handle is hinged, and the other long measuring handle can move in the bar-shaped chute on the measuring ruler, that is, the straight line between the clamping cross bar and the contact point of the cable is not parallel to the measuring ruler when it is in the measuring state, but exists certain angle
The above two points will cause errors in the cable section obtained by the measuring instrument, reducing the measurement accuracy of the cable

Abstract

The invention discloses a cable cross section measuring instrument with high measuring precision, which comprises a clamping part for placing a cable horizontally. The upper side and the lower side of the clamping part are provided with a first measuring mechanism and a second measuring mechanism; the clamping part has a V-shaped cross section and is formed by a first side plate and a second side plate arranged symmetrically, and the top parts of the first side plate and the second side plate form a cable placing port; the first measuring mechanism comprises a supporting plate with one end hinged with the upper end of the first side plate, the other end of the supporting plate is buckled on the upper end of the second side plate, the middle part of the supporting plate is provided with a vertical first through hole, and the first through hole is internally provided with a first vertical rod; the second measuring mechanism comprises a second through hole arranged below the clamping part, and the second through hole is internally provided with a second vertical rod; and axes of the first through hole and the second through hole coincide with the symmetrical shaft of the first side plate and the second side plate. According to the cable cross section measuring instrument, the measuring precision is high, the cable diameter can be quickly measured, the cable cross section is thus acquired, the type can be judged conveniently, and the functional check efficiency is improved.

Description

technical field [0001] The invention relates to a tool for measuring the section diameter of a cylindrical object, belongs to the technical field of measuring instruments, and in particular relates to a cable section measuring instrument. Background technique [0002] Due to historical reasons, some cables are not listed and the data is not well preserved, resulting in the lack of basic information on the cables, which brings a lot of inconvenience to the operation and maintenance work. When verifying cable information on site, how to judge the cable cross-section and cable material has become a difficult point. These originally mainly rely on the experience of operators to judge the cable cross-section, which brings great challenges to inexperienced equipment operators. Although the vernier caliper can measure the cable diameter more accurately, it has certain limitations in use. The vernier caliper has high requirements on the environment. Long-term use in a humid environm...
