[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figure 1 、2 As shown in Figures 3 and 4, this embodiment proposes a multi-angle adjustable mining cap, including a mining cap body 1, a ratchet 2 and a protective ring 3. The bottom of the mining cap body 1 is rotatably connected to the ratchet 2, and the top of the ratchet 2 is provided with a protective ring 3. A lighting mechanism is fixed on the protective ring 3. A ratchet mechanism is provided between the bottom of the mining cap body 1 and the ratchet 2. The mining cap is worn on the head when in use. The protective ring 3 is fixed to the top of the ratchet 2 by screws, covering the top of the ratchet 2 to protect the ratchet 2. Since the lighting mechanism is fixed to the protective ring 3, it can rotate with the ratchet 2 and self-lock in position to adjust the illumination angle of the lighting mechanism, making it more practical.

[0020] The ratchet mechanism includes a tooth groove 6, a pawl 7 and a paddle 8. A plurality of tooth grooves 6 are distributed in an equidistant ring on the inner side of the ratchet 2. The pawl 7 is rotatably connected to one side of the bottom of the mining cap body 1. The paddle 8 is also fixedly connected to one side of the bottom of the mining cap body 1.

[0021] One end of the pawl 7 is engaged with the inner wall of the tooth groove 6 , and one end of the paddle 8 is fitted with one end of the pawl 7 . The material of the paddle 8 is set to be an elastic spring.

[0022] When the ratchet 2 is rotated counterclockwise, the tooth groove 6 on the ratchet 2 will also drive the pawl 7 to rotate counterclockwise, so that the pawl 7 exits the inside of the tooth groove 6 to avoid interfering with the rotation of the ratchet 2, and the paddle 8 is in a bent state. After being adjusted to a suitable position, the elastic force generated by the paddle 8 is used to drive the tooth groove 6 to rotate clockwise and reset, and one end of the pawl 7 is engaged in the adjacent tooth groove 6. At this time, the position of the ratchet 2 can be locked, and the lighting mechanism is fixed to the ratchet 2 through the protective ring 3, and then the position of the lighting mechanism is adjusted.

[0023] The lighting mechanism includes a miner's lamp 5 and a switch 15. The switch 15 is installed on the top of the miner's lamp 5. The light source of the switch 15 is set to be a semiconductor LED, and an integrated circuit is provided inside the miner's lamp 5. The switch 15 is electrically connected to the miner's lamp 5 through the integrated circuit. When the switch 15 is pressed, an electrical signal is generated between the switch 15 and the integrated circuit. The integrated circuit transmits the electrical signal to the inside of the miner's lamp 5 for controlling the turning on and off of the miner's lamp 5.

[0024] The top of the protective ring 3 is fixedly connected to a base plate 4, and an arc groove is provided on one side of the base plate 4. The base plate 4 is fitted and connected to the outer wall of the mining cap body 1 through the arc groove. The arc groove on one side of the base plate 4 can eliminate the interference between the mining cap body 1 and itself, thereby preventing the base plate 4 from affecting the rotation of the lighting mechanism.

[0025] One side of the base plate 4 is fixedly connected to a buckle 12 by a fixing bolt, and an insert plate 13 is engaged with the inner side of the buckle 12. The top of the insert plate 13 is hinged to one side of the miner's lamp 5 through a nylon hinge seat 14. The buckle 12 is fixed to the base plate 4 by a fixing bolt, and the insert plate 13 is inserted into it along the inner side of the buckle 12. The buckle 12 and the insert plate 13 are engaged together to fix the miner's lamp 5 on the miner's cap. The nylon hinge seat 14 can increase the friction between the miner's lamp 5 and the insert plate 13, so that the position of the miner's lamp 5 is locked when the miner's lamp 5 is rotated to adjust its illumination angle.

[0026] The buckle 12, the insert plate 13 and the fixing bolt are made of plastic materials with good wear resistance and durability such as polypropylene PP and polymethacrylate POM. The plastic material is light in weight and can effectively reduce the overall weight of the mining cap.

[0027] The bottom of the mining cap body 1 is symmetrically fixedly connected with a top strap 9, and the bottom end of the top strap 9 is fixedly connected with a retractable strap 10. The connecting end of the retractable strap 10 is provided with a buckle 11. The top strap 9 and the retractable strap 10 can form an annular structure through the buckle 11, which is used to wear the mining cap on the head. The buckle 11 can adjust the length of the retractable strap 10 to adapt to people of various body shapes.

[0028] When the ratchet 2 is rotated counterclockwise, the tooth groove 6 on the ratchet 2 will also drive the pawl 7 to rotate counterclockwise, so that the pawl 7 exits the inside of the tooth groove 6 to avoid interfering with the rotation of the ratchet 2, and the paddle 8 is in a bent state. After being adjusted to a suitable position, the elastic force generated by the paddle 8 is used to drive the tooth groove 6 to rotate clockwise and reset, and one end of the pawl 7 is engaged with the adjacent tooth groove 6. At this time, the position of the ratchet 2 can be locked, and the lighting mechanism is fixed to the ratchet 2 through the protective ring 3, and then the position of the lighting mechanism is adjusted to make it more practical.
