A wire reel with automatic wire take-up function for electrical test

Abstract

The invention relates to a wire coil with an automatic wire winding function for an electrical test. The wire coil comprises a lower end cover, an upper end cover, a coil spring winding device, a winding wheel, an upper wire winding disc, a coil spring, a wire cable connector device, an automatic emergency stop device, a wire cable dust removing device, a wire cable and the like. The winding wheel is arranged on the lower end cover. The coil spring winding device is arranged inside the winding wheel. The coil spring is arranged between the coil spring winding device and the winding wheel. The upper wire winding disc is arranged on the winding wheel. The wire cable connector device is arranged in the position, located above the upper wire winding disc, of the winding wheel. The wire cable penetrates through the winding wheel to be connected with the wire cable connector device. The wire cable dust removing device and the automatic emergency stop device are sequentially arranged at a wire cable inlet of the wire disc. When the wire coil winds the wire cable, the winding speed of the wire cable is decreased before the wire cable reaches the winding tail end, the phenomenon that the winding speed is excessively large, so that the tail end of the wire cable hurts a human body is avoided. Meanwhile the wire cable dust removing device sweeps the recycled wire cable to keep the wire cable clean. The wire coil totally adopts the mechanical structure, so that energy is saved, and the using range is enlarged.

Description

technical field [0001] The invention belongs to the technical field of cable management devices, and in particular relates to a cable reel with an automatic wire take-up function for electrical testing. Background technique [0002] In the electrical test process, it is often necessary to temporarily connect or extend the wiring. Most of the existing wire reels are manual winding, which has a slow winding speed and a large footprint, which brings great changes to users. At the same time, there are also some automatic take-up boxes in the market. The speed of these take-up boxes is too fast, and the end of the cable will injure people. [0003] On February 14, 2015, the Chinese patent published a patent for a reel with the application number 201510079959.3. This patent includes a cylinder wound to the wire or cable, a turntable and a fixed disk respectively arranged at both ends of the cylinder and the drive described The cylinder reversely rotates the motor, the cylinder ca...
