For example, in this embodiment, the sliding direction of the adjusting element 3240 may be substantially parallel to the axial direction of the through hole 3230, so that when the adjusting element 3240 drives the connecting band 310 to move, the connecting band 310 does not contact the housing 3210 excessively, and the connecting band 310 connected to the adjusting element 3240 is prevented from generating a large pressure with the housing 3210 when moving through the through hole 3230, thereby preventing a large friction force from being generated between the connecting band 310 and the housing 3210 to hinder the movement of the connecting band 310, so that the connecting band 310 can be smoothly tightened or loosened.

Referring to fig. 4 and 5, the returning member 3270 can be connected to the adjusting member 3240 and can provide a returning force to the adjusting member 3240 in a direction toward the through hole 3230, so that the adjusting member 3240 tends to move in a direction close to the through hole 3230. When the connecting band 310 needs to be tightened, the adjusting member 3240 moves in a direction away from the through hole 3230 by an external force, so as to drive the connecting band 310 to move into the accommodating cavity 3220 through the through hole 3230, thereby achieving the purpose of tightening the connecting band 310; when the connecting band 310 needs to be loosened, the external force disappears, the restoring force applied by the restoring member 3270 to the adjusting member 3240 moves the adjusting member 3240 toward the through hole 3230, and the adjusting member 3240 drives the connecting band 310 to move out of the accommodating cavity 3220 through the through hole 3230, so that the connecting band 310 is loosened.

As an embodiment, the restoring member 3270 may be disposed in the accommodating cavity 3220, and one end of the restoring member 3270 is connected to the adjusting member 3240, and the other end of the restoring member 3270 is wound around the housing 3210 and close to the through hole 3230, for example, the restoring member 3270 may be a coil spring, and the coil spring may be wound around the housing 3210 by a shaft, and when the adjusting member 3240 is away from the through hole 3230, the wound portion of the coil spring extends along the through hole 3230.

In other embodiments, a guide shaft may be disposed in the accommodating cavity 3220, the adjusting element 3240 is sleeved on the guide shaft and can slide along the guide shaft, and a spring is sleeved on the guide shaft as a return element 3270, one end of the spring is connected to the housing 3210, the other end of the spring is connected to the adjusting element 3240, and the spring is located on a side of the adjusting element 3240 away from the through hole 3230, and the spring may be always in a compressed state, so that the spring applies a return force to the adjusting element 3240 in a direction toward the through hole 3230, and further drives the adjusting element 3240 to move toward the through hole 3230.

Referring again to fig. 4, a locking member 3250 is disposed in the accommodating cavity 3220, the locking member 3250 can be selectively connected to or disconnected from the adjusting member 3240, and in some embodiments, the locking member 3250 is provided with a first helical tooth 3251, the first helical tooth 3251 is inclined toward a direction away from the through hole 3230, the adjusting member 3240 is provided with a second helical tooth 3241 matched with the first helical tooth 3251, referring to fig. 4, 5 and 6, when the locking member 3250 is connected to the adjusting member 3240, the first helical tooth 3251 is engaged with the second helical tooth 3241, the adjusting member 3240 is limited to slide toward the through hole 3230, the adjusting member 3240 can move only in one direction away from the through hole 3230, referring to fig. 4, 7 and 8, when the locking member 3250 is disconnected from the adjusting member 3240, the first helical tooth 3251 is disengaged from the second helical tooth 3241, and the adjusting member 3240 slides toward the through hole 3230.

In other embodiments, the adjusting element 3240 can include a ratchet and a pawl, the ratchet can selectively engage with the locking element 3250, and the ratchet can be connected with the connecting band 310, when the locking element 3250 can slide with the adjusting element 3240 in a direction away from the through hole, when the ratchet is connected with the locking element 3250, the locking element 3250 can slide in a direction away from the through hole to drive the ratchet to translate and rotate simultaneously, when the ratchet does not limit rotation of the ratchet, when the locking element 3250 tends to move in a direction towards the through hole 3230, the locking element 3250 can also tend to drive the ratchet to rotate in a reverse direction, and when the pawl limits rotation of the ratchet to self-lock.

Referring to fig. 4, 5 and 7, in some embodiments, the pressing portion 3280 is connected to the locking member 3250, the housing may be provided with a pressing hole 3218 communicating with the accommodating cavity 3220, an axial direction of the pressing hole 3218 is substantially perpendicular to an axial direction of the through hole 3230, the pressing portion 3280 is disposed in the pressing hole 3218 and at least partially protrudes out of the housing 3210, and the pressing portion 3280 is configured to drive the locking member 3250 to move, so that the locking member 3250 is selectively connected to or separated from the adjusting member 3240. For example, when an external force is applied to the pressing portion 3280, the locking member 3250 is driven to gradually move away from the adjusting member 3240, so that the locking member 3250 is separated from the adjusting member 3240, and at this time, the adjusting member 3240 is no longer limited by the locking member 3250, and can move towards the through hole direction under the action of a restoring force of the restoring member 3270, so that the connecting band is released; when an external force is applied to the pressing portion 3280 and drives the locking member 3250 to gradually approach the adjusting member 3240, the locking member 3250 is connected and engaged with the adjusting member 3240.

In other embodiments, the pressing portion 3280 may be further configured as a cam, and specifically, a cam may be disposed on the inner wall 3211 of the housing 3210, a rotating shaft of the cam extends out of the housing 3210 and is connected to a knob as the pressing portion 3280, the cam is driven to rotate by rotating the knob, when a contact position of the cam and the locking member 3250 is within a range of a push angle of the cam, the cam drives the locking member 3250 to move toward a direction of the reset member 3260, so that the locking member 3250 gradually moves away from the adjusting member 3240 until disengaging, when the contact position of the cam and the locking member 3250 is within a range of a return angle of the cam, the locking member 3250 gradually approaches the adjusting member 3240 until connecting with the adjusting member 3240, and when the locking member 3250 is connected with the adjusting member 3240, the cam and the locking member 3250 disengage.

In addition, in other embodiments, a user can press the pressing portion 3280 to enable the adjusting member 3240 to be matched with the locking member 3250, and then slide the pressing portion 3280 to enable the adjusting member 3240 to slide relative to the locking member 3250, so as to tighten the connecting band 310; when the user removes the force applied to the pressing portion 3280, the adjuster 3240 is locked such that the adjuster 3240 cannot move relative to the latch 3250.

Referring to fig. 4, 5 and 7, in the embodiment, the resetting element 3260 is located between the locking element 3250 and the adjusting element 3240 and located on a side of the locking element 3250 away from the pressing portion 3280, the resetting element 3260 is disposed in the accommodating cavity 3220 along the pressing direction of the pressing portion 3280 and is configured to provide a resetting force to the locking element 3250, the pressing portion 3280 is configured to enable the locking element 3250 to be selectively connected to or separated from the adjusting element 3240, when an external force is not applied to the pressing portion 3280, the restoring force of the resetting element 3260 enables the locking element 3250 to be connected to the adjusting element 3240, and when the external force is applied to the pressing portion 3280, the pressing portion 3280 drives the locking element 3250 to compress the resetting element 3260 and overcome the resetting force, so as to enable the locking element 3250 to be separated from the adjusting element 3240.

In some embodiments, referring to fig. 3 again, the resetting element 3260 may include a first resetting element 3261 and a second resetting element 3262, and specifically, referring to fig. 4 and 5 again, the first resetting element 3261 and the second resetting element 3262 extend in a direction substantially perpendicular to the axial direction of the through hole 3230, two ends of the first resetting element 3261 abut against the locking element 3250 and the housing 3210, and two ends of the second resetting element 3262 abut against the locking element 3250 and the housing 3210, respectively, the first resetting element 3261 and the second resetting element 3262 are spaced apart from each other, and when the first resetting element 3261 and the second resetting element 3262 are compressed, the first resetting element 3261 and the second resetting element 3262 both apply a force to the locking element 3250 to make the locking element 3250 approach the adjusting element 3240, so that the locking element 3250 tends to approach the adjusting element 3240, thereby driving the locking element 3250 to be coupled with the adjusting element 3240.

In addition, relative positions of the latch 3250, the first reset element 3261 and the second reset element 3262 may be adjusted, so that the first reset element 3261 and the second reset element 3262 respectively abut against two ends of the latch 3250, the pressing portion 3280 may be located between the first reset element 3261 and the second reset element 3262, a moment generated by the pressing portion 3280 and the first reset element 3261 acting on the latch 3250 at the same time may partially offset a moment generated by the pressing portion 3280 and the second reset element 3262 acting on the latch 3250 at the same time, and a situation that the latch 3250 is tilted when the pressing portion 3280 acts on the latch 3250 may be avoided as much as possible. Specifically, in this embodiment, the first and second reset members 3261 and 3262 can be springs, and the housing 3210 and the locking member 3250 have mounting holes at corresponding positions, and the springs are disposed in the corresponding mounting holes. With the above structure, when the latch 3250 compresses the first and second reset members 3261 and 3262, the first and second reset members 3261 and 3262 are not twisted excessively to generate a force parallel to the direction of the through hole 3230, so that the first and second reset members 3261 and 3262 are damaged, and the latch 3250 cannot generate an original reset force to fail. In other embodiments, the first and second returning elements 3261 and 3262 can be made of other elastic materials, such as elastic rubber.

With reference to fig. 4 and fig. 5, in the present embodiment, the resetting element 3260 may further include a third resetting element 3263, the third resetting element 3263 is located between the first resetting element 3261 and the second resetting element 3262, for example, the distance between the third resetting element 3263 and the first resetting element 3261 may be equal to the distance between the third resetting element 3263 and the second resetting element 3262, and the third resetting element 3263 is increased to increase the resetting force of the resetting element 3260 on the locking element, so that the locking element is not easily disengaged when the locking element is connected to the adjuster.

In addition, referring to fig. 4 and fig. 9 again, in order to ensure the stability of the pressing portion 3280 during the pressing process, in some embodiments, a first slider 3212 and a second slider 3213 may be disposed on the inner wall 3211 of the housing 3210, the first slider 3212 and the second slider 3213 may be disposed opposite to each other, the extending directions of the first slider 3212 and the second slider 3213 may be substantially parallel to the axial direction of the pressing hole 3218, and the pressing portion 3280 is slidably disposed between the first slider 3212 and the second slider 3213, so that the pressing portion 3280 may move along the extending direction of the sliders, thereby avoiding the locking member 3250 from tipping.

In other embodiments, the housing 3210 protrudes outward at the pressing hole 3218 for a distance to form a channel communicating with the pressing hole 3218, the cross-sectional shape of the channel is adapted to the cross-sectional shape of the pressing portion 3280, the pressing portion 3280 protrudes out of the channel through the mounting hole, and a small gap exists between the pressing portion 3280 and the channel to avoid the pressing portion 3280 contacting the channel excessively and obstructing the movement of the pressing portion 3280 along the extending direction of the channel.

Referring to fig. 4 again, in this embodiment, the adjusting mechanism 320 further includes a sliding key 3290 for driving the adjusting element 3240, meanwhile, the housing 3210 may further include a sliding slot 3214 communicating with the accommodating cavity 3220, an extending direction of the sliding slot 3214 is substantially parallel to an axial direction of the through hole 3230, the sliding key 3290 is connected to a fixing rod, the sliding key 3290 is slidably disposed in the sliding slot 3214 through the fixing rod, a portion of the fixing rod extending into the accommodating cavity 3220 through the sliding slot 3214 is connected to the adjusting element 3240, so that the sliding key 3290 drives the adjusting element 3240 to slide in the accommodating cavity 3220 when sliding in the sliding slot 3214, and the adjusting element 3240 drives the connecting band 310 to move to adjust the tightness of the connecting band 310.

The embodiment of the present invention provides a working principle of a headband 30: when the connecting band 310 needs to be tightened, the reset force applied by the reset piece 3260 to the locking piece 3250 enables the locking piece 3250 to be connected with the adjusting piece 3240, and meanwhile, the sliding key 3290 is pushed towards the direction away from the through hole 3230 to drive the adjusting piece 3240 to move so as to drive the connecting band 310 and tighten the connecting band 310, the adjusting piece 3240 is always matched with the locking piece 3250 in the moving process, and meanwhile, due to the inclined tooth transmission structure adopted when the adjusting piece 3240 is matched with the locking piece 3250, the restoring force applied by the restoring piece 3270 is limited so that the adjusting piece 3240 tends to move towards the through hole 3230.

When it is necessary to release the connection band 310, the pressing portion 3280 applies a force to the latch 3250 so that the latch 3250 compresses the reset element 3260 and moves toward the reset element 3260, so that the latch 3250 gradually moves away from the adjuster 3240 until completely disengaged, and the adjuster 3240 disengaged from the latch 3250 moves toward the through hole 3230 by the restoring force of the restoring element 3270 and releases the connection band 310.
