[0021] As Figures 1-4 shown, the present utility model provides a technical solution: a protective clothing headband that is convenient to adjust, including a main body 1. The right end of the main body 1 is slidably connected with an adjusting device 2. The right end of the adjusting device 2 is rotatably connected with an adjusting knob 3. The inside of the adjusting knob 3 is provided with an extending mechanism 4 that facilitates the staff to twist the adjusting knob 3. The right end of the adjusting knob 3 is provided with an anti-misoperation mechanism 5 to prevent the staff from accidentally touching it.
[0022] The above-mentioned extending mechanism 4 includes: a movable slot 41, a limiting spring 42, a limiting block 43, a hinge rod 44, a connecting block 45, a pressing block 46, a sliding block 47, a limiting slot 48, and a resilient spring 49. The movable slot 41 is opened on the right side of the adjusting knob 3. Both sides of the inner wall of the movable slot 41 are fixedly connected with the limiting spring 42. The front end of the limiting spring 42 is fixedly connected with the limiting block 43. The shape of the limiting block 43 is triangular. When the sliding block 47 moves downward, it can squeeze the limiting block 43, causing the limiting spring 42 to rebound and push the limiting block 43 to move inward, enabling the sliding block 47 to continue moving downward, moving the limiting slot 48 to the front of the limiting block 43, and allowing the limiting block 43 to be inserted into the limiting slot 48, preventing the sliding block 47 from moving, thereby realizing the limitation of the sliding block 47. The left end of the hinge rod 44 is hinged to the right end of the limiting block 43. The right end of the hinge rod 44 is hinged with a connecting block 45. The right side of the connecting block 45 is fixedly connected with a pressing block 46. The shape of the pressing block 46 is circular. The inner wall of the movable slot 41 is slidably connected with two groups of sliding blocks 47, and the central axis of the main body 1 placed vertically is axisymmetric, enabling the sliding blocks 47 to extend from both ends of the adjusting knob 3, increasing the force-bearing area of the adjusting knob 3, enabling the staff to turn the knob better, avoiding the occurrence of slipping, and making the adjustment of the main body 1 more efficient. Limiting slots 48 are opened on both sides of the sliding block 47. A resilient spring 49 is fixedly connected below the sliding block 47. The resilient spring 49 has an effect of fixing and resetting the sliding block 47. When the sliding block 47 is released from the limit, it pushes the sliding block 47 to extend out of the adjusting knob 3, thereby increasing the force-bearing area of the adjusting knob 3, enabling the staff to effectively adjust the adjusting knob 3 even when their palms are sweating, and avoiding the inability to effectively adjust due to the slipping of the adjusting knob 3, resulting in an increase in the adjustment time.
[0023] The above-mentioned anti-misoperation mechanism 5 includes: a sliding slot 51, a protective cover 52, and a spring hinge 53. A sliding slot 51 is opened on the right side of the adjusting knob 3. The right side of the sliding slot 51 is slidably connected with a protective cover 52. The protective cover 52 protects the pressing block 46, preventing the staff from accidentally touching it when wearing protective clothing, resulting in the extension of the sliding block 47, and blocking it when the staff removes the protective clothing, thereby increasing the time for removing the protective clothing. The front end of the protective cover 52 is provided with a spring hinge 53. The spring hinge 53 has an effect of limiting and supporting the protective cover 52. When the protective cover 52 is reset, the spring hinge 53 rebounds and flips backward to limit the protective cover 52, preventing the staff from accidentally touching it and causing the sliding block 47 to extend, thus affecting the staff's removal and wearing, and the lower half of the spring hinge 53 is fixedly connected to the right side of the adjusting knob 3.
[0024] Working principle: When the staff's palm sweats, causing the adjustment knob 3 to slip, first push the protective cover 52, so that the protective cover 52 moves forward along the chute 51, causing the protective cover 52 to squeeze the spring hinge 53, causing the spring hinge 53 to flip forward, releasing the limit on the protective cover 52, enabling the protective cover 52 to move forward, thus releasing the protection of the pressing block 46, allowing the staff to press the pressing block 46. When the staff presses the pressing block 46, the pressing block 46 pushes the connecting block 45 to move downward and squeezes the hinge rod 44, causing the hinge rod 44 to flip downward and push the limit block 43 to move outward, compressing the limit spring 42, causing the limit block 43 to leave the limit groove 48, thus releasing the limit on the sliding block 47, enabling the elastic spring 49 to rebound and push the sliding block 47 to move outward, causing the sliding block 47 to extend out of the adjustment knob 3, thereby increasing the force-bearing area of the adjustment knob 3, enabling the staff to effectively adjust the adjustment knob 3 when the palm sweats, avoiding the inability to effectively adjust due to the slippage of the adjustment knob 3, resulting in an increase in the adjustment time, and avoiding the increase in the wearing time leading to the staff being unable to reach the work location in time, thus affecting work efficiency.
[0025] After the adjustment is completed and worn, press the sliding block 47, causing the elastic spring 49 to compress, causing the sliding block 47 to move downward, moving the limit groove 48 to the front of the limit block 43, causing the limit spring 42 to rebound, and pushing the limit block 43 to move inward, causing the limit block 43 to snap into the limit groove 48, making the sliding block 47 unable to move, thus realizing the limit on the sliding block 47, avoiding the obstruction of the headgear when wearing the protective headgear, making it inconvenient for the staff to wear. When the limit block 43 moves inward, it pushes the hinge rod 44 to flip upward and pushes the connecting block 45 to move upward, resetting the pressing block 46, facilitating the staff's next use. Then pull the protective cover 52, so that the protective cover 52 moves backward along the chute 51, causing the protective cover 52 to no longer squeeze the spring hinge 53, causing the spring hinge 53 to flip backward, limiting the protective cover 52, avoiding the staff accidentally touching and causing the sliding block 47 to extend, and causing the staff to be blocked when removing the protective headgear, thus affecting the staff's removal and wearing.
[0026] The above generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
