[0030] In one embodiment, Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, an easy-pull buckle 10 includes: an upper cover 100, a lower cover 600, a turntable 200, a pull cord 210, a power generation component 300 and a lighting component 400. The upper cover 100 and the lower cover 600 are connected to each other. The upper cover 100 is provided with a mounting cavity 101. The turntable 200 is rotatably arranged in the mounting cavity 101. The first end of the pull cord 210 is connected to the turntable 200. The pull cord 210 is wound around the turntable 200. The second end of the pull cord 210 is passed through the mounting cavity 101. The electrical assembly 300 includes a magnetic member 310 and a coil winding 320. One end of the magnetic member 310 is fixedly connected to the turntable 200. The other end of the magnetic member 310 defines a placement cavity 311. A mounting member 312 is provided at the bottom of the placement cavity 311. The coil winding 320 is sleeved on the mounting member 312. The connection terminals of the lighting member 400 are electrically connected to the coil winding 320. The light-emitting end of the lighting member 400 extends to the outside of the upper cover 100 and / or the lower cover 600. Specifically, a wire outlet hole 103 is defined in the upper cover 100, which communicates with the mounting cavity 101. The second end of the pull cord 210 passes through the wire outlet hole 103 and protrudes to the outside of the mounting cavity 101. One end of the magnetic member 310 is fixedly connected to the turntable 200 via adhesive or a fastening member. The magnetic element 310 generates a magnetic field. Pulling the pull cord 210 causes the turntable 200 and the magnetic element 310 to rotate together. This magnetic field generated by the magnetic element 310 rotates and continuously interacts with the coil winding 320, generating a current that is output to the lighting element 400, thereby illuminating the lighting element 400, which is electrically connected to the coil winding 320. This arrangement allows the lighting element 400 to be illuminated without the need for additional dry cell batteries or rechargeable batteries, making it easier for users to use. It should be noted that the lighting element 400 is an LED lamp bead.

[0031] In one embodiment, Figure 2 and Figure 3 As shown, a winding groove 201 is provided on the rotating disk 200, and the pull rope 210 is wound in the winding groove 201. Specifically, the winding groove 201 can prevent the pull rope 210 from falling off the rotating disk 200 when the pull rope 210 is pulled.

[0032] In one embodiment, Figure 2 、 Figure 3 and Figure 4As shown, the easy-open buckle 10 further includes: a spring 110, which is mounted on the turntable 200. A clamping block 102 is provided at the bottom of the mounting cavity 101. The inner end of the spring 110 is connected to the clamping block 102, and the outer end of the spring 110 is connected to the turntable 200. Specifically, a spring clamping slot 202 for mounting the spring 110 is provided on the turntable 200. The spring 110 is placed in the spring clamping slot 202 and the inner end of the spring 110 is clamped by the clamping block 102. The outer end of the spring 110 is connected to the side wall of the spring clamping slot 202, so that a connection is formed between the spring 110 and the turntable 200, thereby preventing the turntable 200 and the spring 110 from being separated from the mounting cavity 101. The pull rope 210 is pulled out of the winding groove 201 by an external force, causing the turntable 200 to rotate. The rotation of the turntable 200 causes the mainspring 110 to deform. When the external force is removed, the mainspring 110 recovers its deformation and generates a force causing the turntable 200 to rotate in the opposite direction. While the turntable 200 rotates in the opposite direction, it can drive the pull rope 210 to rewind into the winding groove 201.

[0033] In one embodiment, Figure 4 As shown, the power generation assembly 300 further includes a circuit board 330, which is electrically connected to the coil winding 320, and the terminals of the lighting element are electrically connected to the circuit board. Specifically, the circuit board 330 is disposed on a side of the coil winding 320 away from the magnetic element.

[0034] In one embodiment, Figure 4 As shown, an inner cavity 602 is provided in the lower cover 600, and a support member 610 is provided at the bottom of the inner cavity 602. The circuit board 330 is fixedly connected to the support member 610. Specifically, the support member 610 can support the circuit board 330, and there are multiple support members 610. Multiple support members 610 can better support the circuit board 330 and prevent the circuit board 330 from shaking; the coil winding 320 is fixedly connected to the circuit board 330. By fixing the circuit board 330 in the lower cover 600, the coil winding 320 is fixed. The magnetic member 310 can achieve the function of fixing the magnetic member 310 and the coil winding 320 in place and rotating relative to the coil winding 320 during use, thereby generating current.

[0035] In one embodiment, Figure 2 、 Figure 3 and Figure 4As shown, the easy-to-pull buckle 10 also includes: a battery 500, and the battery 500 is arranged in the lower cover 600, and the battery 500 is electrically connected to the circuit board 330. Specifically, the electricity generated by the pull rope 210 cooperating with the rotating disk to drive the magnetic part 310 to rotate can be transmitted to the battery 500 through the circuit board 330, and the battery 500 can store the generated electricity. Specifically, the lighting part 400 can directly use the electricity generated by the coil winding 320 for lighting, or use the electricity in the battery 500 for lighting. It should be noted that storing the electricity generated by the cooperation between the magnetic part 310 and the coil winding 320 through the battery 500 is a common technical means used by those skilled in the art, and its implementation principle and implementation structure will not be described in detail.

[0036] In one embodiment, a fixing groove 601 is formed on the side wall of the lower cover 600. The light-emitting end of the lighting element 400 extends through the fixing groove 601 to the outside of the lower cover 600, and the lighting element 400 abuts against the groove wall of the fixing groove 601. Specifically, the fixing groove 601 can support the lighting element 400 and prevent it from shaking.

[0037] In one embodiment, Figure 1 and Figure 4 As shown, a stopper 700 is provided on the second end of the pull cord 210. Specifically, the stopper 700 facilitates pulling the pull cord 210 out of the winding groove 201. When the pull cord 210 is retracted into the winding groove 201, the stopper 700 abuts against the sidewall of the outlet hole 103, preventing the second end of the pull cord 210 from being retracted into the winding groove 201. The stopper 700 has a through hole, through which a hanging buckle can be mounted on the stopper 700, thereby allowing keys or badges to be hung on the hanging buckle.

[0038] In one embodiment, the easy-open buckle 10 further includes a USB port and / or a Type-C port, the USB port or the Type-C port being electrically connected to the circuit board 330, and the USB port or the Type-C port extending to the exterior of the upper cover 100 and / or the lower cover 600. Specifically, a voltage regulator and a current limiter are also electrically connected to the circuit board 330, and the power in the battery 500 is supplied to the USB port or the Type-C port after passing through the voltage regulator and the current limiter. In this way, the power in the battery 500 can be used to power an external load via the USB port or the Type-C port. For example, in outdoor situations, the USB port or the Type-C port can be used to temporarily charge a mobile phone for emergency purposes.
