[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1-5 An electronic wristband for fire protection includes a wristband body 1 and a strap 2. A metal part 2 4 is installed on one side of the wristband body 1. The metal part 2 4 includes a connecting groove 41. A hanging ring 42 is fixedly installed inside the connecting groove 41. Both ends of the connecting groove 41 are connected to a pressing groove 44. A pressing plate 45 is slidably arranged in the pressing groove 44. The pressing plate 45 is connected to the inner wall of the pressing groove 44 by a spring 2 46. A pressure rod 43 is fixedly installed on one side of the pressing plate 45. A metal part 1 3 is installed on one end of the strap 2. A mounting bracket 31 is fixedly installed on one side of the metal part 1 3. The mounting bracket 31 is adapted to the connecting groove 41. Movable grooves 312 are opened on both sides of the mounting bracket 31. The movable grooves 312 correspond to the pressing grooves 44. A spring 1 314 is installed inside the movable groove 312. The spring 1 314 is connected to a limiting block 313. The limiting block 313 is slidably arranged in the movable groove 312.

[0024] Specifically, one end of the wire saw is connected to the hanging ring 42. When connecting the metal part 3 at one end of the watch strap 2 to the metal part 4 on one side of the bracelet body 1, first align the mounting bracket 31 on the metal part 3 with the connecting groove 41 of the metal part 4, and then insert the mounting bracket 31 into the connecting groove 41. During the insertion process, the side wall of the connecting groove 41 presses against the limiting block 313, causing the limiting block 313 to press against the spring 314 and retract into the moving groove 312. When the limiting blocks 313 in the moving grooves 312 on both sides of the mounting bracket 31 correspond to the pressing grooves 44 at both ends of the connecting groove 41, due to the elastic force of the spring 314, the limiting block 313 will be pushed into the moving groove 312, thereby realizing the connection between the metal part 3 and the metal part 4.

[0025] When a wire saw is needed, press the pressure rod 43 on the metal part 4. The pressure rod 43 pushes the extrusion plate 45 to slide within the extrusion groove 44, and the extrusion plate 45 stretches the spring 46. As the extrusion plate 45 moves, it presses the limiting block 313 inserted into the extrusion groove 44, causing the limiting block 313 to overcome the elastic force of the spring 314 and retract into the moving groove 312. At this time, pull the metal part 3 at one end of the watchband 2 out of the connecting groove 41 of the metal part 4 on one side of the bracelet body 1, completing the separation of the metal part 3 from the metal part 4.

[0026] The limiting block 313 is fixed by engaging the compression groove 44, forming a mechanical interlocking structure. Compared with some simple buckle or magnetic connection methods, it can withstand greater tensile and external forces, effectively preventing the accidental separation of metal part 3 and metal part 4 in scenarios such as fire fighting where there may be a large range of movements and accidental pulling. Example

[0027] To prevent the wire saw from accidentally unwinding during winding, please refer to [link / reference needed]. Figures 1-5 Based on embodiment 1, a through groove 311 is provided in the middle of the mounting bracket 31. The through groove 311 is connected to the rotating groove 32, which is located inside the metal part 3.

[0028] A sliding frame 33 is fixedly installed on one end of the rotating groove 32, and a sliding plate 35 is slidably installed in the sliding frame 33. The sliding plate 35 is connected to one end of the rotating groove 32 by a spring 34.

[0029] A fixing rod 321 is fixedly installed at the other end of the rotating groove 32, and a limit groove 322 is provided on the end of the fixing rod 321 near the sliding plate 35.

[0030] The fixing rod 321 is set inside the take-up roller 36, and the limiting plate 362 is fixedly installed inside the take-up roller 36. The limiting plate 362 is correspondingly matched with the limiting groove 322.

[0031] A baffle 361 is fixedly installed on the take-up roller 36. One end of the take-up roller 36 passes through the baffle 361 and the sliding plate 35 and is fixedly connected to the handle 37. The handle 37 is located on the outside of the metal part 3.

[0032] Specifically, the other end of the wire saw is wound onto the take-up roller 36. Under normal conditions, the sliding plate 35 is controlled by the spring 34 to restrict the baffle 361, thereby causing the limiting plate 362 in the take-up roller 36 to connect with the limiting groove 322. The limiting groove 322 restricts the limiting plate 362, thereby preventing the take-up roller 36 from rotating. This ensures the stability of the wire saw being wound on the take-up roller 36 and prevents the wire saw from becoming loose.

[0033] When it is necessary to rewind or unwind the wire saw, the operator pulls the handle 37. The fixed connection between the handle 37 and the take-up roller 36 causes the take-up roller 36 to move towards the sliding plate 35. This pushes the sliding plate 35 along the sliding frame 33, compressing the spring 34 and causing the limiting plate 362 to move out of the limiting groove 322. This allows the operator to control the rotation of the take-up roller 36 through the handle 37. By rotating the handle 37 in different directions, the wire saw can be rewound or unwound.

[0034] Working principle: Under normal conditions, one end of the wire saw is connected to the hanging ring 42, and the other end is wound onto the take-up roller 36. Metal part 3 is connected to metal part 4. When the wire saw needs to be used, the operator pulls the handle 37, causing the take-up roller 36 to move towards the sliding plate 35, pushing the sliding plate 35 along the sliding frame 33, compressing the spring 34 and causing the limiting plate 362 to move out of the limiting groove 322. By rotating the handle 37, the operator controls the rotation of the take-up roller 36 to release the wire saw. During this process, the operator... With the other hand, press down the pressure rod 43 on the metal part 2 4. The pressure rod 43 pushes the extrusion plate 45 to slide in the extrusion groove 44, extruding the limiting block 313 inserted in the extrusion groove 44. The limiting block 313 overcomes the elastic force of the spring 1 314 and retracts into the moving groove 312. Then, while controlling the wire saw to release, the operator pulls the metal part 1 3 at one end of the watch strap 2 out of the connecting groove 41 of the metal part 2 4 on one side of the wristband body 1, completing the separation of the metal part 1 3 from the metal part 2 4, so that the wire saw can continue to extend.
