Description

Technical Field

[0001] This application relates to the field of cable reel technology, and in particular to a cable reel with intermittent on / off switching of electrical signals. Background Technology

[0002] A cord reel is a device used to neatly and conveniently store and unload linear items such as electrical wires.

[0003] For existing devices, the power supply remains on while the cord is being retracted. If the live plug or socket collides with other metal objects during rapid movement, it can easily generate sparks, or even cause short circuits or electric shocks. Therefore, the safety of the device is not high. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a cable reel with intermittent on / off switching of electrical signals, thus solving the problem of low device safety.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a reel for intermittent switching of electrical signals, comprising a housing and a reel, the reel being disposed within the housing, the housing comprising an upper cover and a lower cover, the upper cover and the lower cover having wire outlet grooves respectively on opposite sides, the reel being located between the upper cover and the lower cover, one end of the reel being located between the two wire outlet grooves, the lower cover being provided with a connecting component for connecting and locking the upper cover, the upper cover and the lower cover being rotatably disposed with a rotating component for rotating together with the reel, the upper cover having a slot on one side, a Hall switch for connecting to an external circuit being fixedly installed at the slot of the upper cover, the rotating component being provided with a magnetic component for changing the magnetic field strength at the Hall switch and activating the Hall switch.

[0006] Furthermore, the rotating assembly includes a winding reel and an annular connecting block. The winding reel is rotatably mounted on the connecting assembly, and the annular connecting block is fixedly installed on the side of the winding reel near the lower cover. The winding coil is rotatably connected to the annular connecting block.

[0007] Furthermore, the magnetic component includes several magnets, and several placement slots are provided on the side of the winding reel near the top cover, with the several magnets respectively fixedly installed in the several placement slots.

[0008] Furthermore, several placement slots are arranged in a circular array on one side of the winding reel.

[0009] Furthermore, the connecting assembly includes a connecting shaft and a screw. A connecting hole is provided on one side of the upper cover. One end of the connecting shaft is fixedly connected to the side of the lower cover near the upper cover, and the other end of the connecting shaft is connected to the upper cover. The winding reel is rotatably connected to the connecting shaft. A threaded groove is provided on the end of the connecting shaft near the upper cover. The screw is located at the connecting hole of the upper cover and is screwed into the threaded groove of the connecting shaft.

[0010] In summary, this application includes at least one of the following beneficial technical effects: When using the device, the coil rotates on the connecting assembly, and the rotating assembly rotates with the coil. When the magnetic component on the rotating assembly rotates to the Hall switch, the magnetic component changes the magnetic field strength at the Hall switch. The Hall switch detects the change in magnetic field strength. When the magnetic field strength exceeds the detection threshold, the device's circuit is turned on. As the coil continues to rotate, the rotating assembly continues to rotate, and the magnetic component on the rotating assembly moves away from the Hall switch, reducing the magnetic field strength at the Hall switch. When the magnetic field strength falls below the detection threshold, the device's circuit is turned off. This process repeats, achieving intermittent switching of the circuit. This avoids the risk of sparks, short circuits, or electric shocks that can easily occur when a live plug or socket collides with other metal objects during rapid movement, thus improving the device's safety.

[0011] When the device is in use, the reel rotates. When a magnet rotates with the reel and reaches the Hall switch, the magnetic field strength increases. When the magnetic field strength reaches the detection threshold of the Hall switch, the Hall switch is turned on, energizing the device. As the reel rotates, the magnet moves away from the Hall switch, and the magnetic field strength decreases. When it falls below the detection threshold, the device is de-energized until the next magnet reaches the Hall switch, at which point the device is energized again. This process repeats, achieving intermittent switching and improving the device's safety. Attached Figure Description

[0014] The present application will be further described in detail below with reference to the accompanying drawings.

[0015] Example, refer to Figures 1-3A reel for intermittent switching of electrical signals includes a housing 1 and a coil 2. The coil 2 is disposed inside the housing 1. The housing 1 includes an upper cover 11 and a lower cover 12. The upper cover 11 and the lower cover 12 have wire outlet grooves on opposite sides. The coil 2 is located between the upper cover 11 and the lower cover 12, with one end of the coil 2 located between the two wire outlet grooves. The lower cover 12 is provided with a connecting component 3 for connecting and locking the upper cover 11. A rotating component 4 is rotatably disposed between the upper cover 11 and the lower cover 12 for rotating together with the coil 2. A slot is provided on one side of the upper cover 11. A Hall switch 5 for connecting to an external circuit is fixedly installed at the slot of the upper cover 11. A magnetic component 6 is provided on the rotating component 4 for changing the magnetic field strength at the Hall switch 5 and activating the Hall switch 5. When using the device, Hall switch 5 is connected to an external circuit via wiring. The coil 2 rotates on the connecting assembly 3, and the rotating assembly 4 rotates with the coil 2. When the magnetic component 6 on the rotating assembly 4 rotates to the Hall switch 5, it changes the magnetic field strength at the Hall switch 5. The Hall switch 5 detects this change in magnetic field strength. When the magnetic field strength exceeds the detection threshold, the device's circuit is activated. As the coil 2 continues to rotate, the rotating assembly 4 continues to rotate, causing the magnetic component 6 on the rotating assembly 4 to move away from the Hall switch 5. The magnetic field strength at the Hall switch 5 decreases. When the magnetic field strength falls below the detection threshold, the device's circuit is deactivated. This process repeats, achieving intermittent switching of the circuit. This avoids the risk of sparks, short circuits, or electric shocks that can easily occur when a live plug or socket collides with other metal objects during rapid movement, thus improving the device's safety.

[0016] The rotating assembly 4 includes a winding reel 41 and an annular connecting block 42. The winding reel 41 is rotatably mounted on the connecting assembly 3, and the annular connecting block 42 is fixedly installed on the side of the winding reel 41 near the lower cover 12. The wire coil 2 is rotatably connected to the annular connecting block 42. When the wire coil 2 rotates on the connecting assembly 3, the wire coil 2 drives the annular connecting block 42 to rotate together, and also causes the winding reel 41 to rotate together. The winding reel 41 can isolate the wire coil 2 from direct contact with the inner wall of the upper cover 11, reducing wear and improving the service life of the device.

[0017] The magnetic component 6 includes several magnets 61. Several placement slots 411 are provided on the side of the reel 41 near the upper cover 11, and the magnets 61 are fixedly installed in the slots 411. When the device is in use, the reel 41 rotates. When a magnet 61 rotates with the reel 41 to the Hall switch 5, the magnetic field strength increases. When the magnetic field strength reaches the detection threshold of the Hall switch 5, the Hall switch 5 conducts, energizing the device. As the reel 41 rotates, the magnet 61 moves away from the Hall switch 5, and the magnetic field strength decreases. When it falls below the detection threshold, the device is de-energized until the next magnet 61 reaches the Hall switch 5, at which point the device is energized again. This process repeats, achieving intermittent switching and improving the device's safety.

[0018] Several placement slots 411 are arranged in a circular array on one side of the winding reel 41. When using the device, by arranging the several placement slots 411 evenly in a circular array on the winding reel 41, the intermittent switching of the device's circuitry is made periodic, further improving the device's working efficiency.

[0019] The connecting assembly 3 includes a connecting shaft 31 and a screw 32. A connecting hole is provided on one side of the upper cover 11. One end of the connecting shaft 31 is fixedly connected to the side of the lower cover 12 near the upper cover 11, and the other end of the connecting shaft 31 is connected to the upper cover 11. A winding reel 41 is rotatably connected to the connecting shaft 31. A threaded groove is provided at the end of the connecting shaft 31 near the upper cover 11. The screw 32 is located at the connecting hole of the upper cover 11 and is screwed into the threaded groove of the connecting shaft 31. During installation, the upper cover 11 and lower cover 12 are joined together by connecting the connecting shaft 31 on the lower cover 12 to the connecting hole of the winding reel 41 and the upper cover 11, and then screwed into the threaded groove of the connecting shaft 31 using the screw 32, thus completing the installation and improving the convenience of the device.

[0020] Working principle: When using the device, the wire spool 2 rotates on the connecting shaft 31, and the arc-shaped connecting block rotates with the wire spool 2, causing the winding reel 41 to rotate. When a magnet 61 on the winding reel 41 rotates to the Hall switch 5, the magnetic component 6 changes the magnetic field strength at the Hall switch 5. The Hall switch 5 detects the change in magnetic field strength. When the magnetic field strength exceeds the detection threshold, the device's circuit is turned on. As the wire spool 2 continues to rotate, the winding reel 41 continues to rotate, and the magnet 61 moves away from the Hall switch 5, reducing the magnetic field strength at the Hall switch 5. When the magnetic field strength is lower than the detection threshold, the device's circuit is turned off until the next magnet 61 rotates to the Hall switch 5. This process repeats, achieving intermittent switching of the circuit. This avoids the risk of sparks or even short circuits or electric shocks that could easily occur if a live plug or socket collides with other metal objects during rapid movement, thus improving the device's safety.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
