Cable testing instrument with charging device

Abstract

The invention, which relates to the cable testing instrument field, particularly provides a cable testing instrument with a charging device. The cable testing instrument comprises a primary testing instrument and a secondary testing instrument. Besides, the cable testing instrument also includes a rocking bar arranged on the primary testing instrument and a handle connected to the rocking bar in a hinge joint; and the rocking bar is fixedly connected to a rotor of a generator and thus the rotor of the generator module is driven to make rotation by rotation of the handle to generate power. And the generator module is also configured to be connected to a rechargeable battery module to store the power into the rechargeable battery module; and the input terminal of the rechargeable battery is connected with an output terminal of a charging control circuit. Because the generator module is arranged inside the cable testing instrument and the handle is rotated to enable the rocking bar to drive the rotor of the generator module to make rotation so as to generate power and the power is stored into the rechargeable battery module, automatic power storage can be realized under the circumstance that the cable testing instrument is not equipped with a changing device, thereby guaranteeing normal usage.

Description

technical field [0001] The invention relates to the field of line measuring instruments, in particular to a line measuring instrument with a power bank. Background technique [0002] At present, the power supply used by line measuring instruments on the market is generally dry batteries. This power supply method not only requires frequent replacement of batteries, but also causes greater environmental pollution if the replaced batteries are discarded. Since on-site operators need to carry a lot of equipment, many of which are rechargeable instruments, if the site does not have power supply conditions and the rechargeable instrument circuits are insufficient, the on-site operators cannot supply power to the rechargeable instruments in time, which will seriously affect work efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a line measuring instrument with a power bank. [0004] The present invention is achiev...

[0002] At present, the power used by line measuring instruments on the market is generally dry batteries. This power supply method not only requires frequent replacement of batteries, but also causes greater environmental pollution if the replaced batteries are discarded.

Since on-site operators need to carry a lot of equipment, many of which are rechargeable instruments, if the site does not have power supply conditions and the circuit of the rechargeable instrument is insufficient, the on-site operator cannot supply power to the rechargeable instrument in time, which will seriously affect the work efficiency
