DETAILED DESCRIPTION
[0020] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a portable self-rescue wristband, comprising a wristband 1, on which an inflatable air bag 2 is fixedly installed, and buckles 3 and buttonholes 4 are respectively provided at both ends of the wristband 1. The wristband 1 is conveniently worn on the user's wrist through the clamping connection between the buckle 3 and the buttonhole 4, and an adjustment box 5 is fixedly installed on the wristband 1, and an adjustment mechanism 6 is provided inside the adjustment box 5.
[0021] In this embodiment, an adjustment mechanism 6 is provided inside the adjustment box 5. The pull rope 66 is rolled up by the winding wheel 65 in the adjustment mechanism 6, so that the wristband 1 can be tightened around the human wrist, and then the tightness of the wristband 1 can be adjusted when used by different users, making it convenient to wear. At the same time, the card block 612 is engaged with the inside of the card slot 67, so that the wristband 1 can be stably fitted to the wrist to complete wearing. The hinge plate 611 is bent upward to drive the card block 612 to move out of the inside of the card slot 67 to release the limit, making it convenient to remove the wristband 1.
[0022] The above-mentioned adjustment mechanism 6 includes a slider 61, which is slidably connected to the inner wall of the adjustment box 5, the outer wall of the slider 61 is fixedly connected to one end of a load-bearing spring 62, and the other end of the load-bearing spring 62 is fixedly connected to the inner wall of the adjustment box 5. A rotating rod 63 is rotatably connected to the outer wall of the slider 61, and a winding wheel 65 is fixedly sleeved on the outer wall of the rotating rod 63. The winding wheel 65 is driven by the rotating rod 63 to wind up the pull rope 66, so that the wristband 1 can tighten the human wrist. A supporting block 64 is slidably connected to the inner wall of the adjustment box 5, and the rotating rod 63 is rotatably connected to the inside of the supporting block 64. A card slot 67 is provided on the supporting block 64, and a pull rope 66 is wound around the winding wheel 65. The end of the pull rope 66 is connected to the wristband 1 is fixedly connected, a hinge block 68 is fixedly installed on the adjustment box 5, and a support rod 69 is rotatably connected to the inner wall of the hinge block 68. The outer wall of the support rod 69 is fixedly connected to one end of the torsion spring 610 and the inner wall of the hinge block 68. The elastic force of the torsion spring 610 can make the card block 612 snap into the inside of the card slot 67, and the wristband 1 can be stably fitted to the wrist through the snap connection. A hinge plate 611 is fixedly sleeved on the outer wall of the support rod 69, and a card block 612 is fixedly installed on the bottom wall of the hinge plate 611. By bending the hinge plate 611 upward, the card block 612 can be driven to move out of the inside of the card slot 67 to release the limit, thereby facilitating the removal of the wristband 1. The bottom of the card block 612 is set in an arc shape.
[0023] In this embodiment, the wristband 1 is first worn on the user's wrist through the engagement between the buckle 3 and the eyelet 4, and then the winding wheel 65 is driven by the rotating rod 63 to wind up the pull rope 66, so that the wristband 1 is tightened around the human wrist. At this time, the support block 64 on the outer wall of the rotating rod 63 is driven to move to the right by the slider 61, and the bottom arc surface of the block 612 is squeezed by the rightward movement of the support block 64, so that the block 612 drives the hinge plate 611 to flip upward, and finally the block 612 is engaged with the inside of the slot 67 through the elastic force of the torsion spring 610. The wristband 1 can be stably fitted to the wrist through the engagement to complete the wearing. When the wristband 1 needs to be removed, the block 612 is driven to move out of the slot 67 by bending the hinge plate 611 upward to release the limit, so that the wristband 1 is convenient to remove.
[0024] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
