Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, and particularly relates to an insulating measuring rod. Background Art

[0002] The insulating measuring rod, also known as a height measuring rod, a telescopic height measuring rod, etc., is a commonly used quick measuring tool in the power industry. It is mainly used to measure the height of wires, the crossing distance of lines, and the distance between the line and the ground. This tool plays an important role in power maintenance and repair work, and can help workers safely and accurately obtain the required measurement data without directly contacting the live body.

[0003] However, in the actual use process, there may indeed be some problems with inconvenient measurement. For example, in some narrow or high places, such as the dense equipment area of the substation, the area with messy lines, and the high-altitude lines, the operating space is limited, and because of the complex environment, the operator may have difficulty directly measuring the position to be measured, resulting in inaccurate positioning or measurement errors, making the insulating measuring rod difficult to operate flexibly, increasing the difficulty and danger of measurement.

[0004] Most of the existing insulating measuring rods are straight rods. If the operating position cannot be directly operated in a straight line with the position where the worker is located, it will undoubtedly significantly increase the operation difficulty. The patent with the application number 201520695481.2 discloses a telescopic insulating measuring rod. By setting exhaust holes on the surface of the epoxy tube, the exhaust holes can adjust the telescoping of the rod during work, and the telescopic rod will not be difficult to telescope due to air pressure; however, it does not solve the problem that in a complex environment, the operator may have difficulty directly measuring the position to be measured, resulting in measurement errors. Therefore, there is an urgent need for a more flexible insulating measuring rod to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, to solve the problem that in a complex environment, the operator may have difficulty directly measuring the position to be measured, resulting in measurement errors;

[0006] The utility model provides an insulating measuring rod, which includes an insulating rod, a measuring head and a measuring device. The measuring head is arranged at the head of the insulating rod, the measuring device is arranged inside the tail of the insulating rod, a fixing ring is arranged at the head of the insulating rod, a rotatable wire reel is arranged at the tail of the insulating rod, and the wire of the measuring device is wound on the wire reel and connected to the measuring head through the fixing ring.

[0007] As a preferred solution, the measuring head is in a hook shape and is hinged to the wire.

[0008] As a preferred solution, a Z-shaped handle is arranged at the end of the wire reel.

[0009] As a preferred solution, the inner end of the handle is fixed to the center of the side surface of the wire reel.

[0010] As a preferred solution, a rotatable sleeve is sleeved on the outer end of the handle.

[0011] As a preferred solution, the insulating rod is arranged as a telescopic rod.

[0012] As a preferred solution, the inner surface of the outermost section of the insulating rod is provided with threads, and the inner and outer surfaces of each section except the outermost section are provided with threads. The threads of adjacent telescopic sections are adapted to each other to achieve telescoping by rotation.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, by providing a ring at the rod head as a fixed pulley, the measuring head can descend along with the wire at the rod head, making the whole device form an L shape to measure measuring positions at more angles that are inconvenient for straight-line measurement, solving the problem of measurement in complex or difficult-to-reach straight-line environments. By providing a ring at the rod head as a fixed pulley, the measuring head slides along the rod head. As the wire descends, the measuring head can flexibly adjust its position and angle, and the whole measuring device forms an L-shaped structure, thus being able to adapt to the measurement requirements at more angles, especially those positions that are difficult to reach by straight-line measurement methods.

[0019] To illustrate the characteristics of the present utility model, the following further describes the present utility model in conjunction with the drawings and embodiments.

[0020] Embodiment 1:

[0021] Please refer to Figure 1, an embodiment of the present utility model provides an insulation measuring rod, which includes an insulating rod 1, a probe 2 and a measuring device. The probe 2 is arranged at the head of the insulating rod 1, and the measuring device is arranged inside the tail of the insulating rod 1. A fixing ring 3 is arranged at the head of the insulating rod 1, and a rotatable wire reel 4 is arranged at the tail of the insulating rod 1. The wire 5 of the measuring device is wound around the wire reel 4 and connected to the probe 2 through the fixing ring 3.

[0022] In this embodiment, the probe 2 is in a hook shape, which is more convenient for hanging on the device to be measured. Being hinged to the wire 5 provides more hanging angles.

[0023] In order to facilitate the rotation of the wire reel 4, a Z-shaped handle 6 is arranged at the end of the wire reel 4, and the inner end of the handle 6 is fixedly connected to the center of the side surface of the wire reel 4. A rotatable sleeve 7 is sleeved on the outer end of the handle 6, so that the wire reel 4 can be rotated most labor-savingly when the handle 6 is shaken.

[0024] In addition, in order to maximize the utilization of the length of the measuring rod, the insulating rod 1 is set as a telescopic rod. The inner surface of the outermost section of the insulating rod 1 is provided with threads. Except for the outermost section, the inner and outer surfaces of each section are provided with threads. One section is sleeved on another section, with the tail on the outermost and the head on the innermost. The threads of adjacent telescopic sections are adapted to each other to achieve telescoping through rotation. Of course, this is just a most easily implemented telescoping scheme, and there are a large number of better schemes to choose from in the prior art.
