In this embodiment, the main head wearing body 10 is in a ring shape and is configured to be worn on the head of a user, two ends of the main head wearing body 10 are respectively provided with an adjusting rack 13, the two adjusting racks 13 are independent from each other, the tooth portions of the two adjusting racks 13 are arranged oppositely, the adjusting gear 30 is installed between the two adjusting racks 13, that is, one of the adjusting racks 13 is meshed with one side of the adjusting gear 30, and the other adjusting rack 13 is meshed with the other side of the adjusting gear 30. When the adjusting gear 30 is rotated in the clockwise direction or the counterclockwise direction, the two adjusting racks 13 can move toward each other to tighten the head-mounted body 10, and when the adjusting gear 30 is rotated in the reverse direction, the two adjusting racks 13 can move toward the direction away from each other to enlarge the head-mounted body 10, so that the tightness of the head-mounted body 10 can be adjusted. The adjusting rack 13 may be assembled to the main head body 10, or may be integrally formed with the main head body 10. In other embodiments, the adjustment rack 13 may be provided only at one end of the main head attachment 10, and the other end of the main head attachment 10 may be fixed to the attachment case 20.

When the guide 50 is provided on the end surface of the adjustment gear 30, the guide 50 is located on one side in the axial direction of the adjustment gear 30, and the rotation axis of the guide 50 is substantially collinear with the axis of the adjustment gear 30. The guide structure is arranged on one side of the adjusting gear 30 facing the guide member 50, and when the locking clip 60 is slidably mounted on the guide structure, namely, the locking clip 60 is located between the adjusting gear 30 and the guide member 50, and when the guide structure provides a guiding effect for the locking clip 60 in the radial direction of the adjusting gear 30, the locking clip 60 can be limited to rotate relative to the adjusting gear 30. Stop ring part 41 ring locate the periphery of locking fastener 60, and stop ring part 41 fixed relative installation casing 20, so when locking fastener 60 is in locking position, locking fastener 60 card is gone into and is stopped a groove 42 to can restrict adjusting gear 30 and stop ring part 41 relative and rotate, also can restrict locking fastener 60 and move towards the direction of keeping away from the unlocking position, can restrict adjusting gear 30 and at installation casing 20 internal rotation, in order to realize that the adjusting device locking of wearing is fixed. The inner peripheral surface of the stopper ring portion 41 is provided with a plurality of stopper grooves 42, and the plurality of stopper grooves 42 are distributed at intervals in the circumferential direction of the stopper ring portion 41.

When the tightness of the head-wearing body 10 needs to be adjusted, the guide piece 50 is rotated, the linkage structure between the guide piece 50 and the locking clamping piece 60 is utilized to drive the locking clamping piece 60 to slide from the locking position to the unlocking position, so that the locking clamping piece 60 is separated from the stop groove 42, and when the locking clamping piece 60 moves to the unlocking position, the guide piece 50 and the locking clamping piece 60 are relatively fixed in the circumferential direction of the adjusting gear 30 through the linkage structure. And since the guide structure can limit the rotation of the locking jaw 60 relative to the adjusting gear 30, the guide 50, the locking jaw 60 and the adjusting gear 30 can be relatively fixed in the circumferential direction of the adjusting gear 30. And when locking clip 60 is in the unlocking position, locking clip 60 cannot move in a direction away from the locking position, i.e. locking clip 60 reciprocates between the locking position and the unlocking position. And then after rotating guide 50 and making locking fastener 60 remove to the unblock position, continue to rotate guide 50 again, can drive adjusting gear 30 through locking fastener 60 and rotate to drive the motion of adjusting rack 13, so as to reach the purpose of adjusting the elasticity of wearing main part 10.

According to the technical scheme of the invention, the guide piece 50 is rotatably arranged on the end face of the adjusting gear 30, and a guide structure is arranged on one side of the adjusting gear 30 facing the guide piece 50, so that the stop ring part 41 of the stop piece 40 is annularly arranged on the periphery of the guide structure, and the inner peripheral surface of the stop ring part 41 is provided with the stop groove 42. And a locking clamping piece 60 which is slidably arranged on the guide structure along the radial direction of the adjusting gear 30 is arranged on the inner side of the stop ring part 41, so that the locking clamping piece 60 has a locking position clamped into the stop groove 42 and an unlocking position separated from the stop groove 42.

When the tightness of the headgear main body 10 needs to be adjusted, the guide member 50 is rotated, and the locking clip 60 is driven to slide from the locking position to the unlocking position by using the linkage structure between the guide member 50 and the locking clip 60, so that the locking clip 60 is separated from the stopper groove 42. And when the locking jaw 60 moves to the unlocking position, the guide member 50 and the locking jaw 60 are relatively fixed in the circumferential direction of the adjusting gear 30 through the linkage structure, so that the guide member 50, the locking jaw 60 and the adjusting gear 30 are relatively fixed in the circumferential direction of the adjusting gear 30. At this time, the guide member 50 is continuously rotated, and the adjusting gear 30 is driven to rotate by the locking fastener 60, so as to drive the adjusting rack 13 to move, thereby adjusting the tightness of the head-wearing main body 10. Since the locking dog 60 is already made to escape from the stopper groove 42 of the stopper ring portion 41 before the driving adjustment gear 30 is rotated, a noise generated by collision of the locking dog 60 with the stopper ring portion 41 can be avoided.

And after the adjustment is accomplished, when making locking fastener 60 be in locking position, can make locking fastener 60 block go into and end a groove 42, thereby can restrict adjusting gear 30 and end a ring portion 41 rotation relatively, can restrict adjusting gear 30 and at installation casing 20 internal rotation, in order to realize wearing adjusting device locking fixed, locking fastener 60 does not produce relative rotation with ending ring portion 41 in this in-process, also can avoid locking fastener 60 and the circumstances that ends ring portion 41 collision noise production.

Referring to fig. 2 and 4 to 8, in an embodiment, the linkage structure includes a first guide rib 51 disposed on the guide 50 and a first sliding protrusion 61 disposed on the locking clip 60, the first guide rib 51 has a first guide surface 511 facing the rotation axis of the guide 50, the guide 50 has a first rotation direction, the first guide surface 511 gradually extends obliquely along the first rotation direction in a direction away from the rotation axis of the guide 50, the first sliding protrusion 61 is in sliding fit with the first guide surface 511, and when the guide 50 rotates along the first rotation direction until the locking clip 60 is in the unlocking position, the first sliding protrusion 61 abuts against the first guide rib 51.

Specifically, the first guide rib 51 is shaped like a bar, the first guide rib 51 gradually extends obliquely in the first rotation direction in a direction away from the rotation axis of the guide 50, that is, the first guide rib 51 and the first guide surface 511 are both oblique to the radial direction of the adjustment gear 30, and the first sliding protrusion 61 is located on a side of the first guide rib 51 toward the rotation axis of the guide 50. When the lock seizing member 60 is located at the locking position, the first slide protrusion 61 is located at an end of the first guide surface 511 remote from the rotation axis of the guide 50. When the guide 50 is rotated in the first rotation direction, the first guide rib 51 gradually presses the first slide protrusion 61 via the first guide surface 511, so that the lock catch gradually moves toward the unlocking position.

The guide 50 is rotated in the first rotational direction, and when the lock catch 60 is located at the unlocking position, the first slide protrusion 61 is located at one end of the first guide surface 511 close to the rotational axis of the guide 50 and abuts on the first guide surface 511. At this time, since the locking dog 60 cannot continue to move far away from the locking position, and the locking dog 60 cannot rotate relative to the adjusting gear 30, the guide 50, the locking dog 60, and the adjusting gear 30 can be relatively fixed in the circumferential direction of the adjusting gear 30. So that the adjusting gear 30 can be rotated in the first rotation direction by the locking dog 60 while the guide 50 continues to rotate in the first rotation direction. Such a simple structure is advantageous for simplifying the structure of the locking jaw 60 and the guide 50. The first guiding surface 511 may be a straight surface, or may be a convex arc surface or a concave arc surface. Of course, the first guide rib 51 may not be strip-shaped, for example, the first guide rib 51 may be block-shaped, and the first guide surface 511 may be formed on the first guide rib 51.

Of course, in another embodiment, the linkage structure includes a guide sliding groove disposed on the guide 50 and a guide convex portion disposed on the locking latch 60, the guide sliding groove gradually extends obliquely along the first rotation direction in a direction away from the rotation axis of the guide 50, the guide convex portion is slidably mounted on a groove side wall of the guide sliding groove close to the rotation axis of the guide 50 and is spaced from the groove side wall of the guide sliding groove far from the rotation axis, when the guide 50 rotates along the first rotation direction to the locking latch 60 is at the unlocking position, the locking latch 60 cannot continue to move far in the direction away from the locking position, so that the guide convex portion can be abutted by the groove side wall of the guide sliding groove close to the rotation axis of the guide 50, thereby the guide 50, the locking latch 60 and the adjusting gear 30 are relatively fixed in the circumferential direction of the adjusting gear 30, so as to drive the adjusting gear 30 to rotate.

In addition, in other embodiments, the linkage structure may further include a guiding protrusion disposed on the guiding element 50 and a guiding sliding groove disposed on the locking dog 60, the guiding sliding groove gradually extends along the first rotation direction in a direction away from the rotation axis of the guiding element 50, and the guiding protrusion is slidably mounted on a groove sidewall of the guiding sliding groove close to the rotation axis of the guiding element 50 and spaced apart from the groove sidewall of the guiding sliding groove away from the rotation axis.

In an embodiment, the linkage structure further includes a second guide rib 52 disposed on the guide 50 and a second sliding protrusion 62 disposed on the locking catch 60, the second guide rib 52 is spaced apart from the first guide rib 51, the second guide rib 52 has a second guide surface 521 facing the rotation axis of the guide 50, the guide 50 has a second rotation direction opposite to the first rotation direction, the second guide surface 521 gradually extends obliquely in the second rotation direction in a direction away from the rotation axis of the guide 50, the second sliding protrusion 62 is in sliding fit with the second guide surface 521, and when the guide 50 rotates in the second rotation direction until the locking catch 60 is in the unlocking position, the second sliding protrusion 62 abuts against the second guide rib 52.

Specifically, if the first rotation direction is the clockwise direction, the second rotation direction is the counterclockwise direction, and if the first rotation direction is the counterclockwise direction, the second rotation direction is the clockwise direction. The second guide rib 52 is in a bar shape, the second guide rib 52 gradually extends obliquely in the second rotation direction in a direction away from the rotation axis of the guide 50, that is, the second guide rib 52 and the second guide surface 521 are both oblique to the radial direction of the adjustment gear 30, and the second sliding protrusion 62 is located on a side of the second guide rib 52 facing the rotation axis of the guide 50. The extending direction of the second guide rib 52 intersects with the extending direction of the first guide rib 51. The first sliding protrusion 61 and the second sliding protrusion 62 are spaced apart in the sliding direction of the lock catch 60, that is, the first guide rib 51 and the second guide rib 52 are spaced apart in the radial direction of the guide 50 (the direction perpendicular to the rotational axis of the guide 50).

When the locking dog 60 is located at the locking position, the second sliding protrusion 62 is located at one end of the second guide surface 521 away from the rotation axis of the guide 50. When the guide 50 is rotated in the second rotation direction, the second guide rib 52 gradually presses the second sliding protrusion 62 by the second guide surface 521, thereby gradually moving the lock catch toward the unlocking position.

At this time, since the locking dog 60 cannot continue to move far away from the locking position, and the locking dog 60 cannot rotate relative to the adjusting gear 30, the guide 50, the locking dog 60, and the adjusting gear 30 can be relatively fixed in the circumferential direction of the adjusting gear 30. So that the adjusting gear 30 can be rotated in the second rotational direction by the locking dog 60 while the guide 50 continues to rotate in the second rotational direction. Thus, the guide member 50 can be rotated in the first rotation direction to contract the head-mounted body 10, and the guide member 50 can be rotated in the second rotation direction to expand the head-mounted body 10 (the guide member 50 can be rotated in the second rotation direction to contract the head-mounted body 10, and the guide member 50 can be rotated in the first rotation direction to expand the head-mounted body 10), so that the noise generated by the collision between the locking fastener 60 and the stop ring portion 41 can be avoided in the process of expanding and locking the head-mounted body 10. And the structure is simple, which is beneficial to simplifying the structures of the locking clamping piece 60 and the guide piece 50.

The second guiding surface 521 may be a straight surface, or a convex arc surface or a concave arc surface. Of course, the second guide rib 52 may not have a bar shape, for example, the second guide rib 52 has a block shape, and the second guide surface 521 may be formed on the second guide rib 52.
