The two positioning posts 2531 are centrally symmetric about the axis of the rotating shaft 26 of the ratchet unlocking plate 253. Correspondingly, the ratchet wheel 251 includes a ratchet body 2512 and is rotatable about the ratchet body 25 12 . Two rotating blocks 2513, two rotating blocks 2513 are arranged one above the other, and two teeth 2511 are respectively located on the two rotating blocks 2513, and each sliding block 2513 is further provided with a sliding slot 2514, two sliding slots 2514 The two positioning posts 2531 of the ratchet unlocking plate 253 are respectively slidably disposed in the two sliding slots 2514. In the normal state, the two positioning posts 2531 are respectively located at the middle of the two sliding slots 2514. When the knob outer ring 23 drives the ratchet unlocking plate 253 to rotate, the two positioning posts 2531 also start to rotate around the rotating shaft 26, The two positioning posts 2531 slide along the two sliding slots 2514, respectively, and are relatively far apart, and when the two positioning posts 2531 are respectively slid to the end positions of the two sliding slots 2514, the positioning post 2531 is difficult to continue moving, and then the ratchet The two rotating blocks 2513 of the 251 generate a force and rotate the two around the ratchet body 2512 at a small angle. The two rotating blocks 2513 also exert a force on the ratchet body 2512 and drive the ratchet body 2512 to rotate, that is, the ratchet 251 rotates integrally. In this case, one of the positioning posts 2531 is adjacent to a corresponding tooth 2511, and the other positioning post 2531 is away from the corresponding tooth 2511, because the positioning post 2531 exerts a force on the rotating block 2513, so that the tooth 2511 is close thereto. Continuing with the ratchet ring 2521 of the ratchet seat 252, the other positioning post 2531 is moved away from its corresponding tooth 2511, thereby making the dial The tooth 2511 can rotate a small angle around the positioning post 2531, that is, the matching relationship between the dial 2511 and the corresponding ratchet ring 2521 is released, and when the entire rotation process is finished, the rotating outer ring does not generate a rotating force, the ratchet The two positioning posts 2531 of the unlocking plate 253 are further slid along the two sliding slots 2514 and are slid to the middle of the two sliding slots 2514. The two teeth 2511 of the cymbal ratchet 251 and the two ratchet rings 2521 of the ratchet seat 252 are both In a coordinated state. In the above structure, the two positioning posts 2531 of the ratchet unlocking plate 253 realize the release of the cooperation relationship between the two outer teeth 23 and the two ratcheting rings 2521, thereby realizing the adjustment of the annular belt diameter. The locking action of the locking assembly 22 is simple in structure and convenient in operation.

Two tension springs 29 are further disposed on the helmet body 1 , and one ends of the two tension springs 29 are respectively fixed to the two racks 13 . The other end of the helmet body 1 is fixed to the helmet body 1. Specifically, the other ends of the two tension springs 29 are fixed on the rear housing 12. Generally, the two tension springs 29 are in a stretched state, and further, in the locking assembly 22 The elastic shaft 261 is generally provided with a resilient member 261. The elastic member 261 is generally a compression spring. The first locking ring 28 of the knob latch 28 and the second ring of the ratchet seat 252 are formed by the elastic member 261. The ring gear 2522 is engaged. On the knob housing 24, a knob button 242 is provided. The knob button 242 abuts the knob latch 28 and is also movable along the length of the elastic member 261. Generally, when the helmet is worn in the position of the head of the human body, the annular belt is often over-tightened due to operation or other reasons. If the outer ring 23 is adjusted by the knob, the adjustment speed may be too slow. In this embodiment, the helmet body 1 is provided with a quick release function, that is, the diameter of the endless belt can be quickly increased, and the specific operation is to directly press the knob button 242, so that the knob button 242 is oriented along the length of the elastic member 261. The inside of the outer casing 24 moves, because the knob button 242 abuts the knob lock 28, thereby forcing the knob lock 28 to compress the elastic member 261, and the knob lock 28 moves along the rotating shaft 26 and the knob button 24 2 in the same direction, the first of the knob lock 28 The meshing state between the ring gear 281 and the second ring gear 2522 of the ratchet seat 252 is released, the locking assembly 22 releases the locking function, and the two tension springs 29 are in a stretched state, and the locking assembly 22 is locked. After being released, the two tension springs 29 have a tendency to restore the original length and generate a pulling force to cause the two racks 13 to move by themselves, thereby sequentially driving the gear 27, the knob housing 24, the ratchet 251, and the ratchet solution in reverse. The plate 253 and the knob outer ring 23 rotate, and the two tension springs 29 continue to drive the two racks 13 to move by themselves, the diameter of the endless belt can be rapidly increased, and in the process, the ratchet seat 252 has no lock of the knob lock 28 Tight action, the role of the ratchet 251 rotates coaxially with it. In the whole process, just press the knob button 24 2, the helmet can quickly increase the diameter of the ring belt, and quickly release the compression of the ring belt and the human head. The operation is very convenient, and after the end of the annular belt is increased, the pressing of the knob button 242 is cancelled, the elastic member 261 is compressed and rebounded, and the abutting knob 28 is moved along the rotating shaft 26 and the knob is locked. The first ring gear 281 of the 28 re-engages with the second ring gear 2522 of the ratchet seat 252, and the locking assembly 22 regenerates the locking function. Of course, the knob button 242 is restored to the original state by the push of the knob lock 28. In the above structure, generally, the flange 26 is protruded from the outer peripheral surface of the rotating shaft 26, and the elastic member 261 is sleeved on the rotating shaft 26, and one end thereof abuts against the flange 262, and the other end The portion abuts against the knob latch 28. The flange 262 allows the elastic member 261 to compress or extend between the flange 262 and the knob latch 28 after the knob button 242 is actuated, thereby implementing the locking assembly 22. Locking function.
