DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] An induction locking nut, such as Figures 1 to 6 As shown, it is mainly used in conjunction with a fixing bolt 1 and a fixing nut 2 for bolt connection. The fixing bolt 1 and the fixing nut 2 are used to connect and fix multiple objects that need to be fixed. The induction anti-loosening nut is used to monitor the fixing nut 2. When the fixing nut 2 is in a thread-removing condition, an alarm is issued in time to enable maintenance personnel to carry out maintenance in time.

[0028] The above-mentioned induction anti-loosening nut includes: a matching induction nut 3 and an induction gasket 4, the induction nut 3 is threadedly installed on the outside of the fixing bolt 1, and the induction gasket 4 is clamped on the top of the fixing nut 2.

[0029] The main body of the induction nut 3 is set as a nut body 301, and a part installation groove 307 is opened at the top of the nut body 301. The inside of the part installation groove 307 is provided with a magnetic induction switch 311, a flashing lamp bead 312, a battery module 313 and a signal transmission module 314 which are connected in series in sequence through wires. When the magnetic induction switch 311 is closed, the circuit is energized, the flashing lamp bead 312 flashes continuously, and the signal transmission module 314 sends a signal of retracting the wire of the fixed nut 2 to the monitoring system; the above-mentioned parts are glued inside the part installation groove 307, and a protective top cover 302 is fixedly installed on the top of the part installation groove 307.

[0030] Reference Figure 5 The part installation groove 307 is set as an open ring groove, that is, the part installation groove 307 is annular as a whole, but the part installation groove 307 is solid between the two ends, and the solid corresponds to a side edge of the outer wall of the nut body 301.

[0031] A positioning socket 1 315 is provided at the bottom end of the magnetic induction switch 311, and a positioning socket 2 316 is provided on one side of the battery module 313. The positioning socket 1 315 and the positioning socket 2 316 are both integrally formed with the nut body 301, so as to facilitate fixing the magnetic induction switch 311 and the battery module 313 and avoid positional displacement between the two during gluing.

[0032] Similarly, the flashing lamp beads 312 and the signal transmission module 314 can also be fixed in the same way to increase the speed of binding.

[0033] The main body of the battery module 313 is set as a button battery, and the number of button batteries used can be determined according to the specific volume of the nut body 301 and the size of the button battery; the signal transmission module 314 includes two parts: a control module and a transmission module. The control module mainly controls the operation of the flashing lamp bead 312, and the transmission module mainly transmits wireless signals, which can use short-range radio frequency signals, Bluetooth signals or Wi-Fi signals, depending on actual usage needs.

[0034] The nut body 301 is mainly made of polymer materials to ensure its overall relative strength, while ensuring its transparency and ability to withstand high temperatures, facilitating the emission of light from the flashing lamp beads 312 while reducing its processing and production costs, such as acrylic materials.

[0035] The nut body 301 may also be made of metal. In this case, a through hole for installing the flashing lamp bead 312 needs to be opened on the main body of the nut body 301 to facilitate the flashing lamp bead 312 to be exposed.

[0036] A mounting slot 303 is provided at the bottom of the front side of the nut body 301 , and a threaded hole is provided on the back side of the slot wall of the mounting slot 303 . The threaded hole penetrates the entity between the two ends of the part mounting slot 307 and communicates with the threaded inner cavity of the nut body 301 .

[0037] A fastening screw 304 is installed in the internal thread of the threaded hole, and a mounting groove is opened at the tail of the fastening screw 304. A rubber top column 308 is fixedly installed in the mounting groove. When the fastening screw 304 is tightened, the rubber top column 308 squeezes the fixing bolt 1 to avoid damaging the thread of the fixing bolt 1.

[0038] A hexagonal groove 309 is provided at the head of the fastening top screw 304, and pin adapter slots 310 are symmetrically provided on both side walls of the hexagonal groove 309. The hexagonal groove 309 facilitates the loading and unloading of the fastening top screw 304. A fixing pin 305 is clamped inside the pin adapter slot 310, and both ends of the fixing pin 305 pass through the slot walls of the mounting slot 303 to fix the fastening top screw 304 and prevent the fastening top screw 304 from being stripped.

[0039] A fixed rubber ring 306 is fixedly installed at the bottom end of the nut body 301, and an interference fit is set between the fixed rubber ring 306 and the fixing bolt 1. When the fixed rubber ring 306 is sleeved on the outside of the fixing bolt 1, the fixed rubber ring 306 will not separate from the fixing bolt 1 without a large external force.

[0040] The induction gasket 4 includes an integrally formed gasket body 401 and a fixed clamping plate 402 . Two mounting holes are symmetrically provided on the upper surface of the gasket body 401 . Induction magnets 403 cooperating with the magnetic induction switch 311 are installed inside the mounting holes.

[0041] The fixing clamping plates 402 are arranged in two symmetrical numbers and are clamped to the outer wall of the fixing nut 2 ; the center line between the two induction magnets 403 and the center line between the two fixing clamping plates 402 are perpendicular to each other.

[0042] Working principle:

[0043] Please refer to Figures 1 to 6 , assemble the device as shown in the figure;

[0044] First, the induction gasket 4 is clamped onto the tightened fixing nut 2 through the fixing clamping plate 402, and then the induction nut 3 is screwed on the fixing bolt 1, so that the magnetic induction switch 311 is close to the induction gasket 4, until the magnetic induction switch 311 of the induction nut 3 is close to the induction magnet 403. At this time, the magnetic induction switch 311 is turned on by the magnetic force of the induction magnet 403, and the flashing lamp bead 312 is powered on and flashes, and then the induction nut 3 is rotated forty-five degrees, the magnetic induction switch 311 deviates from the induction magnet 403, and the alarm state is released (the flashing lamp bead 312 flashes); then the tightening top screw 304 is tightened, so that the rubber top column 308 squeezes the fixing bolt 1, and the tightening top screw 304 is fixed by the fixing pin 305, so that the nut body 301 is fixed to the fixing bolt 1;

[0045] When the fixing nut 2 is stripped, the induction gasket 4 is driven to move synchronously, so that the induction magnet 403 triggers the magnetic induction switch 311. After the signal transmission module 314 is powered on, the automatic control transmission module sends a signal that the fixing nut 2 is stripped to the monitoring system, and controls the flashing lamp 312 to flash continuously. The maintenance personnel can quickly determine the fixing nut 2 with stripped wire and perform maintenance based on the alarm issued by the monitoring system and the position where the flashing lamp 312 flashes continuously.

[0046] Note: When the vibration generated in the use environment of the fixing bolt 1 has little effect on the fixing bolt 1, the tightening top screw 304 can be omitted. The static friction between the fixing rubber ring 306 and the fixing bolt 1 can ensure the stability of the sensing nut 3 and avoid the deflection and thread withdrawal of the sensing nut 3 itself.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
