Portable cable diameter measuring device

Abstract

The invention provides a portable cable diameter measuring device. The portable cable diameter measuring device comprises a handle and two measuring boxes connected to the front end and the rear end of the handle respectively. Each measuring box is of a cuboid structure, four independent copper wire nose through holes are formed in the side wall of the side, away from the handle, of each measuringbox, copper wire noses are arranged in the copper wire nose through holes in a matched mode, four button through holes are formed in the top of each measuring box, and buttons are arranged in the button through holes in a matched mode; four copper wire nose pop-up devices are arranged in the measuring box, one end of each copper wire nose pop-up device is connected with one button, and the otherend of each copper wire nose pop-up device is connected with one copper wire nose; and under the driving of the button, the copper wire nose popping device pops up the copper wire nose from the copperwire nose through hole. The device is simple to operate and wide in applicability, can accurately judge whether the diameter of the cable with the triangular section and other non-circular sections meets the diameter standard of the standard cable or not in the cable acceptance work, and accurately measures the diameter of the cable.

Description

technical field [0001] The invention relates to the technical field of cable diameter detection, in particular to a portable cable diameter measuring device. Background technique [0002] Measuring the cable diameter is an important task in the cable acceptance process. For cables with traditional circular cross-sections, the cable diameter can be measured directly with a vernier caliper. However, for the circumscribed circle diameter of a triangular cross-section cable, at present, only the method of measuring the circumscribed circle diameter by measuring three sides can be used for calculation. However, due to the irregular shape of the cable, the calculation error is relatively large, which often does not match the actual diameter of the circumscribed circle, and the calculation is more complicated. The mathematical level of the on-site acceptance personnel is required to be high, and the applicability is poor. [0003] Accordingly, there is an urgent need for a cable ...

However, for the circumscribed circle diameter of the triangular cross-section cable, at present, only the method of measuring the circumscribed circle diameter by measuring three sides can be calculated.

However, due to the irregular shape of the cable, the calculation error is relatively large, and the actual diameter of the circumscribed circle often does not match the situation, and the calculation is more complicated. The mathematical level of the on-site acceptance personnel is required to be high, and the applicability is poor.
