Problems solved by technology

[0003] 1. There are many specifications of low-voltage wires in operation at present, and the signs of sun and rain are blurred, and some specifications have little difference between them, which cannot be distinguished by naked eyes
[0004] 2. Low-voltage wires are mostly erected at a height of about 3 meters. If you want to identify the wire diameter, you need to use a ladder to measure the distance, which is dangerous and inefficient
[0007] Publication number: CN210014731U, discloses a type measuring tool for overhead wires, including an inner member and an outer member, the outer member is slidably sleeved on the inner member, the outer member is connected with an outer measuring arm, the inner member is connected with an inner measuring arm, and the outer member is connected with an outer measuring arm. The component is provided with an indicator plate, and the inner component is connected with an indicator piece that matches the indicator plate. The device drives the component in a sliding manner, and the relative position of the component needs to be fixed by a limit piece, so the measurement accuracy is low, and Components are easy to shift and difficult to measure accurately

Embodiment 1

[0029] like Figure 4 As shown, a low-voltage wire section measuring instrument includes an upper clip 10, a lower clip 20, a main body 30 and a driving rod, wherein, in this embodiment, the main body 30 is a cylindrical structure, and a cavity is provided in the main body 30 Two ends of the main body 30 are provided with openings communicating with the cavity, and the lower clip 20 is fixedly connected to the outer wall of the upper end of the main body 30 . The driving rod includes a first rod body 401 and a sleeve body 50. The first rod body 401 is movably arranged in the cavity. The upper end of the first rod body 401 passes through the upper end opening of the main body 30 and is connected with the upper clip 10. The lower end of the body 30 passes through the opening and is connected with the sleeve body 50 , which is movably sleeved on the outer wall of the main body 30 .

[0030]Wherein, in this embodiment, the driving rod is movably connected with the main body 30 th...

Embodiment 2

[0036] like figure 1 , 2 As shown, this embodiment is similar to Embodiment 1, the difference is that in this embodiment, the thread pair includes a third threaded part 302 and a fourth threaded part 402, and the third threaded part 302 is a threaded part arranged on the inner wall of the cavity. The internal thread, the fourth threaded part 402 is an external thread provided on the outer wall of the first rod body 401, and the third threaded part 302 and the fourth threaded part 402 cooperate with each other. Due to the action of the third threaded portion 302 and the fourth threaded portion 402 , by rotating the first rod 401 , the first rod 401 can move upward or downward to drive the action of the upper clip 10 .

Embodiment 3

[0038] like Figure 5 As shown, this embodiment is similar to Embodiment 1 or 2, the difference is that, in this embodiment, the driving rod includes a second rod body 601, a nut 602 is connected to the outside of the main body 30, the second rod body 601 is a threaded rod, and the screw thread The rod cooperates with the nut 602 , an indicating block 603 is arranged on the threaded rod, and the end of the threaded rod is connected with the upper clip 10 . Due to the action of the third threaded portion 302 and the fourth threaded portion 402 , by rotating the first rod 401 , the first rod 401 can move upward or downward to drive the action of the upper clip 10 .

[0039] Further, a handle 604 is also included, and the handle 604 is connected with the end of the second rod body 601 . The handle 604 can increase the holding area, which is convenient for the staff to rotate the second rod body 601 .

Description

technical field [0001] The present invention relates to the technical field of measuring devices, and more particularly, to a low-voltage wire section measuring instrument. Background technique [0002] In the process of acceptance and verification of distribution network infrastructure projects, it is often necessary to identify and confirm low-voltage conductors of various diameters, but there are the following difficulties: [0003] 1. At present, there are many specifications of low-voltage wires in operation, and the signs of sun and rain are blurred, and some specifications have little difference between them, which cannot be distinguished by naked eyes. [0004] 2. Low-voltage wires are mostly erected at a height of about 3 meters. If you want to identify the wire diameter, you need to use a ladder to measure the distance, which is dangerous and inefficient. [0005] Due to the lack of convenient and effective measurement tools, the type of overhead conductors erecte...
