Description

Reel

The invention relates to a reel, in particular to a reel which can correctly display the actual length of the retractable wire.

In order to facilitate storage and carrying, most of the long-length wires are stored by winding the wires into a circular shape, and in order to facilitate the winding of the wires, the design of the reel is provided, and the reel is supported by the support frame and the wire. The wheel is composed of a wire wheel for winding the wire, and the support frame is used for supporting the wire reeling, but the design of the reeling disk also has its problems. Since the wire has no marked length, it cannot be used when the wire is used. Knowing the length of the wire that is currently being sent, it is impossible to know the length of the wire that has been involved in the winding. If you want to mark the wire on the wire, there will be a problem that the cost is too high, and the time is one. The scale on the long wire material may be worn out and not easily recognized. Therefore, how to make the general reel has the effect of indicating the length of the retractable wire, it is necessary to propose a suitable improved solution that is convenient to use and low in cost.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a reel that can correctly display the length of an actual retractable wire, thereby designing to solve the problem that the aforementioned reel cannot be known in length.

In order to achieve the foregoing, the present invention provides a reel, comprising a reel, a support frame, a counter, and at least two receiving components, wherein the reel is provided with a transmitting component, and the receiving frame is provided with a receiving component. When the wire wheel rotates, the receiving component senses the transmitting signal emitted by the transmitting component to generate an output signal, and detects the number of rotations and the direction of rotation of the wire wheel by the number of output signals sent by the receiving component, thereby Calculate the length of the wire that the wire is sent or wound in at different turns, and indicate the length of the wire on the meter to improve the utility of the wire reel.

A transmitting element 11 is disposed on one side of the wheel 10, and the transmitting element 11 can emit more than one transmitting signal; the supporting frame 20 has a first supporting strip 21 and a second supporting strip 22, and the first supporting strip 21 and the One end of the second support bar 22 is pivotally connected to the reel 10 . Specifically, the support frame 20 can have a triangular structure, and one end of the triangle is pivotally connected to the axle 12 of the reel 10 so that the reel 10 can be rotated. The support frame 20 is supported, so that the reel 1 can be The position is idling, the first support strip 21 is provided with a first receiving element 211, and the second support strip 22 is provided with a second receiving element 221, the positions of the receiving elements are corresponding to the launch on the reel 10 The position of the component 11 includes a microprocessor 31, a retractable line input circuit 32, and a display 33. The retractable line input circuit 32 is coupled to the receiving component and the microprocessor 31 for Receiving the output signals of the receiving components, and sending the output signals to the microprocessor 31 for processing, and the microprocessor 31 receives the output signals to detect the number of revolutions of the current reel 10, and using the circular formula The first receiving component 211 and the second receiving component 221 are respectively coupled to the receiving and receiving line input circuit 32. Therefore, when the wire wheel 10 rotates, the first receiving component 211 and the second receiving component 221 sense After the transmitting signal emitted by the transmitting component 11, the first receiving component 211 and the second receiving component 221 respectively generate an output signal, and the output signals are sent to the microprocessor 31 through the receiving line input circuit 32 for calculation. The number of rotations of the reel 10 can be detected by the number of output signals, and the number of turns can be converted into a length by the microprocessor 31, and displayed on the display 33 on the counter 30, the display 33 can be liquid crystal The display device, and the transmitting component 11 may be a magnet or an infrared light emitting diode. When the emitting component 11 is a magnet, the receiving component (211, 221) may specifically be a reed switch to match the magnet. When the reed switch senses the magnetic force of the magnet, an output signal is generated; when the transmitting element 11 is an infrared illuminating diode, the receiving component (211, 221) may specifically be a photoelectric crystal or a photodiode. When the infrared light emitting diode emits an infrared signal, the photoelectric crystal or the photodiode generates an output signal when receiving the infrared signal, and the present invention does not use the transmitting component 11 and receive The combination of components (211, 221) is limited.

In an embodiment of the present invention, in addition to detecting the number of rotations of the reel 10 by the number of output signals, the rotation direction of the reel 10 can also be detected. When the reel 10 rotates clockwise, The receiving components will receive the transmitting signals emitted by the transmitting component 11 in the order of the second receiving component 221 and the first receiving component 211, and send the output signals, so that after the receiving and outputting circuit 32 receives the output signals, When transmitted to the microprocessor 31 for processing, the microprocessor 31 can know the direction of rotation of the reel 10 according to the order of the output signals, and can also know that the wire is currently being sent or is being wound into the wire; When the wheel 10 rotates counterclockwise, the receiving components receive the transmitting signals emitted by the transmitting component 11 in the order of the first receiving component 211 and the second receiving component 221, and sequentially send the output signals through the output signals.
