Description

Technical Field

[0001] The utility model relates to the technical field of electric wires, and in particular to a device for measuring the diameter of an electric wire sheath. Background Art

[0002] Wires refer to conductors that transmit electrical energy. They are divided into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires, and various profiles (such as profiled wires, busbars, copper bars, aluminum bars, etc.). They are mainly used for outdoor overhead and indoor busbars and switch boxes. Electromagnetic wires are insulated wires that generate a magnetic field or induce current in a magnetic field when energized. They are mainly used for motor and transformer windings and other related electromagnetic equipment. The conductor is mainly copper wire, which should have a thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance, etc. Different insulation materials can be used to obtain different characteristics.

[0003] The patent specification with announcement number CN209991932U discloses a pipe diameter measuring device, which clamps the pipe by a bottom rod and a measuring rod, and accurately obtains the pipe diameter value by the cooperation of the fixed end of the magnetostrictive displacement sensor and the movable magnetic ring, making the measurement value more accurate. At the same time, the pipe diameter value is transmitted to a display and displayed through the display end of the display, which is easy to read. The overall structure is simple and easy to operate.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during use, the above device clamps the pipeline through the bottom rod and the measuring rod, and accurately obtains the diameter value of the pipeline through the cooperation of the fixed end of the magnetostrictive displacement sensor and the movable magnetic ring, but its operation is relatively complicated. When the bottom rod and the measuring rod are used to clamp the pipeline, the elastic rope is prone to fatigue after long-term use, thereby affecting the elastic effect of the elastic rope. If it is not maintained and replaced in time, the service life of the equipment will be reduced. Therefore, further improvement is needed. Utility Model Content

[0029] like Figure 4As shown, a placement circular block 26 is slidably provided inside the active plate 25 and the support block 1, a notch 261 is penetrated through one side of the placement circular block 26, a limit block 262 is fixedly connected to the outer surface of the placement circular block 26, one end of the placement circular block 26 is fixedly connected to a connecting rod 263, one end of the connecting rod 263 is fixedly connected to a ring block 264, an elastic rope 27 is fixedly connected to the outer surface of the ring block 264, the other end of the elastic rope 27 is fixedly connected to another group of ring blocks 264, the placement circular block 26 is slidably connected to the inside of the circular groove 2132, the limit block 262 is slidably connected to the limit groove 2133, the notch 261 is communicated with the through groove 2131, and the elastic rope 27 is used to pull the follower plate 213 to move back, so that the follower plate 213 and the base block 24 can effectively fix the wire sheath.
