[0002] In the fields of power engineering, communication engineering, and others, accurate measurement of wire and cable length is crucial. To achieve this goal, various wire and cable length measuring devices have emerged. These devices are usually based on mechanical or electronic principles and use different technical means to record and calculate the length of the cable.

[0003] One common measurement method is to indirectly obtain the length of the cable by measuring the rotation of the drum. This method uses a rotary encoder to record the number of turns of the cable passing through a certain point and calculates the total length of the cable accordingly. However, this method faces some challenges in practical application.

[0004] Firstly, when the wire and cable is pulled on the measuring drum, it is prone to left and right swinging. This swinging not only increases the uncertainty of the measurement, but also may cause the wire and cable to accidentally detach from the measuring drum, thereby affecting the accuracy and stability of the measurement.

[0005] Secondly, the measuring drum is usually exposed to the outside and is easily disturbed by external factors. For example, debris in the environment may adhere to the drum, affecting the rotation of the drum and the accuracy of the measurement. In addition, accidental touching of the drum by the operator during operation may also cause measurement errors or damage to the equipment.

[0006] Therefore, we need to provide a wire and cable length measuring device. UTILITY MODEL CONTENT

The measuring device 3 is responsible for recording and processing measurement data. A display screen is mounted on the measuring device 3 to display the length data of the wire / cable. The motor 4 is mounted on the top rear side of the mounting base 1, located inside the connecting shell 2. The output shaft of the motor 4 is connected to the measuring wheel 5. The motor 4 provides power to drive the measuring wheel 5 to rotate, thereby moving the wire / cable and measuring its length. A measuring wheel 5 is also mounted at the front end of the measuring device 3. The rear ends of the two measuring wheels 5 are connected by a pulley assembly 6. The measuring wheels 5 contact the wire / cable, and their rotation measures the length of the wire / cable. The two measuring wheels 5 rotate synchronously through the pulley assembly 6. The pulley assembly 6 consists of... The device consists of two pulleys and a flat belt. A protective shell 7 is connected to the front top of the mounting base 1. The protective shell 7 is located outside the two measuring wheels 5 and is used to protect the measuring wheels 5 from external interference and damage. The left and right sides of the protective shell 7 have openings for the power supply cable to pass through, and the rear ends of the two measuring wheels 5 rotate through the rear side of the protective shell 7. The protective shell 7 can protect the two measuring wheels 5. A sliding cover 8 is slidably connected to the front side of the protective shell 7.
