Detailed ways

Fig. 1 has shown the reel structure of the present utility model, and reel 1 comprises line reel 10, a support frame 20, a counting table 30 and at least two receiving elements above, will use the first receiving element in the present embodiment 211. The second receiving element 221 is used to illustrate the application of two receiving elements. The utility model does not limit the number of receiving elements to only two; the wire wheel 10 is used for winding the wire on it, specifically, the wire is wound on the wire wheel On the wheel shaft 12 of 10, the two sides of the wheel shaft 12 are structures that prevent the wire rod from falling off from the wheel shaft 12 after the wire is wound around the wheel shaft 12. This structure forms a disk surface, which can be formed by a disc or several support bars. As a limit, a radiating element 11 is provided on one side of the reel 10, and the radiating element 11 can emit more than one transmitting signal; the support frame 20 has a first support bar 21 and a second support bar 22, and the first support One end of the bar 21 and the second support bar 22 is pivotally connected to the wire wheel 10. Specifically, the support frame 20 can be in a triangular structure, and one end of the triangle is pivoted to the axle 12 of the wire wheel 10, so that the wire wheel 10 can be rotated by Supported by the support frame 20 so that the reel 1 can idle in a fixed position, the first support bar 21 is provided with a first receiving element 211, and the second support bar 22 is provided with a second receiving element 221, these The position that the receiving element is provided with corresponds to the position of the transmitting element 11 on the wire wheel 10; the counting meter 30 includes a microprocessor 31, a pay-and-play line input circuit 32 and a display 33 inside, and the pay-and-play line input circuit 32 connects these receivers. The components and the microprocessor 31 are used to receive the output signals of the receiving components, and send these output signals to the microprocessor 31 for processing, and the microprocessor 31 uses these output signals to detect the number of rotations of the current wire wheel 10, The length can be calculated by using the circle formula; the first receiving element 211 and the second receiving element 221 are respectively connected to the take-up and release line input circuit 32, so when the wire wheel 10 rotates, the first receiving element 211 and the second receiving element 221 receive After receiving the transmission signal emitted by the transmitting element 11, the first receiving element 211 and the second receiving element 221 generate an output signal respectively, and the output signal is sent to the microprocessor 31 for calculation through the receiving and releasing line input circuit 32, and by The number of rotations of the wire wheel 10 can be measured by these output signal quantities, and the number of turns can be converted into length through the microprocessor 31, and displayed on the display 33 on the meter 30, the display 33 can be a liquid crystal display, and the emission The element 11 can specifically be a magnet or an infrared light-emitting diode.
