In the embodiment of the present application, the thumb wheel 30 can be switched between the locked state and the unlocked state by connecting the thumb wheel 30 to the first strap 10 and the second strap 20, respectively, and movably connecting the thumb wheel 30 to the housing. In the case that the tightness of the first strap 10 and the second strap 20 needs to be adjusted, the thumb wheel 30 can be switched to the unlocking state, and at this time, the limiting mechanism is separated from the thumb wheel 30, and the tightness of the first strap 10 and the second strap 20 can be adjusted by rotating the thumb wheel 30. In the case of adjusting the tightness of the first strap 10 and the second strap 20 in place, a restraining mechanism may be at least partially embedded in the dial wheel 30 to restrain the rotation of the dial wheel 30 so that the dial wheel 30 is switched to a locked state so that the tightness of the first strap 10 and the second strap 20 is maintained at a proper level. The adjusting device 100 according to the embodiment of the present application can facilitate the adjustment of the tightness of the first strap 10 and the second strap 20, and can also achieve the secure fixing of the first strap 10 and the second strap 20 and prevent the loosening of the first strap 10 and the second strap 20.

As shown in fig. 1, the housing may specifically include a first housing A0 and a second housing 40, the first housing A0 and the second housing 40 may enclose an accommodating space for accommodating the first strap 10, the second strap 20, and the limiting mechanism, and at least a portion of the thumb wheel 30 may extend into the accommodating space.

For example, the first casing A0 may be a front casing, the second casing 40 may be a rear casing, and the first casing A0 and the second casing 40 may be connected by snapping, screwing, or the like. Openings a01 may be provided at both ends of the first casing A0, and the first strap 10 and the second strap 20 may enter the accommodating space from the openings a01 at both ends of the first casing A0, respectively, and may be coupled with the thumb wheel 30 at least partially extending into the accommodating space.

Referring to fig. 3, a schematic structural diagram of a thumb wheel according to an embodiment of the present application is shown, and as shown in fig. 3, the thumb wheel 30 may specifically include: a knob 301 and a center shaft 306 connected to the knob 301; wherein, the knob 301 is arranged outside the shell; central shaft 306 extends at least partially into the housing and is connected to first strap 10 and second strap 20, respectively; the central shaft 306 is provided with a limiting groove 303, and the central shaft 306 can move along the axial direction to realize the switching between the locking state and the unlocking state. When the thumb wheel 30 is in the locked state, at least part of the limiting mechanism is embedded in the limiting groove 303 to limit the rotation of the thumb wheel 30. When the thumb wheel 30 is in the unlocked state, the limiting mechanism is disengaged from the limiting groove 303 to release the limitation of the thumb wheel 30 by the limiting mechanism, so that the tightness degree between the first strap 10 and the second strap 20 is adjusted by the rotation of the thumb wheel 30.

In a specific application, the central shaft 306 of the thumb wheel 30 can move axially to drive the limiting groove 303 on the central shaft 306 to move axially along the central shaft 306 correspondingly. When the limiting groove 303 moves to a position opposite to the limiting mechanism, the limiting mechanism can be just at least partially embedded in the limiting groove 303, and due to the limiting effect of the limiting mechanism, the thumb wheel 30 cannot rotate, and the first bandage 10 and the second bandage 20 can be kept at the current tightness degree. When the position-restricting groove 303 is away from the position opposed to the position-restricting mechanism, the position-restricting mechanism can be disengaged from the position-restricting groove 303 to release the restriction of the position-restricting mechanism to the thumb wheel 30, so that the tightness between the first strap 10 and the second strap 20 can be adjusted by the rotation of the thumb wheel 30. That is, the dial 30 can be switched between the locked state and the unlocked state by moving the central shaft 306 of the dial 30, and the structure is simple and easy to implement.

Referring to fig. 4, which shows a schematic structural diagram of a second housing according to an embodiment of the present application, as shown in fig. 4, a mounting hole 401 is provided on the second housing 40, and a central shaft 306 on the thumb wheel 30 can extend into an accommodating space defined by the second housing 40 and the first housing A0 through the mounting hole 401 to connect with the first strap 10 and the second strap 20 located in the accommodating space.

As shown in fig. 2, a portion of the first strap 10 extending into the housing is provided with a first rack 101, a portion of the second strap 20 extending into the housing is provided with a second rack 201, and the engaging teeth 501 of the gear 50 are engaged with the first rack 101 and the second rack 201, respectively. Thus, in the case that the thumb wheel 30 rotates the gear 50, the first rack 101 and the second rack 201 can be driven to move relatively close to each other or move away from each other, so as to achieve tightness adjustment of the first strap 10 and the second strap 20.

In a specific application, the first rack 101 may be engaged on the top of the gear 50, and the second rack 201 may be engaged on the bottom of the gear 50, so that, during the rotation of the gear 50 in the first direction, the first rack 101 and the second rack 201 may be driven to move close to each other to tighten the first strap 10 and the second strap 20; during the rotation of the gear 50 in the second direction, the first rack 101 and the second rack 201 may be moved away from each other to loosen the first strap 10 and the second strap 20.

Illustratively, the first direction and the second direction are opposite. For example, in the case where the first direction is a clockwise direction, the second direction is a counterclockwise direction; in a case where the first direction is a counterclockwise direction, the second direction is a clockwise direction.

In some alternative embodiments of the present application, one of the transmission groove 502 and the transmission wall 302 is disposed on the central shaft 306, and both the transmission groove 502 and the transmission wall 302 extend along the axial direction of the central shaft 306; the gear 50 is provided with a second through hole 503, the gear 50 is sleeved outside the central shaft 306 through the second through hole 503, the hole wall of the second through hole 503 is provided with the other one of the transmission groove 502 and the transmission wall 302, and the transmission wall 302 is embedded in the transmission groove 502 to realize the connection between the gear 50 and the central shaft 306, so that the gear 50 can rotate together with the central shaft 306, and the malposition rotation between the gear 50 and the central shaft 306 is prevented. In this way, when the knob 301 of the thumb wheel 30 is rotated by the hand of the user, the gear 50 is driven to rotate, so that the first rack 101 and the second rack 201 are driven to move by the rotation of the gear 50, and the tightness of the first strap 10 and the second strap 20 is adjusted.

It should be noted that, in the drawings of the embodiments of the present application, only the case where the protruding transmission wall 302 is provided on the central shaft 306 and the transmission groove 502 adapted to the structure of the transmission wall 302 is provided on the gear 50 is shown. In practical applications, the transmission wall 302 may be disposed on the gear 50, and the transmission groove 502 may be disposed on the central shaft 306, and the specific positions of the transmission wall 302 and the transmission groove 502 may not be limited in the embodiments of the present application.

In a specific application, since the position-limiting post 70 is connected to the bracket 80 through the elastic member 60, under the condition that the position-limiting groove 303 on the central shaft 306 moves to a position opposite to the position-limiting post 70, the position-limiting post 70 can be at least partially embedded in the position-limiting groove 303 under the elastic force of the elastic member 60, so as to limit the rotation of the thumb wheel 30. When the position of the limit groove 303 is away from the position opposite to the limit mechanism, the elastic member 60 can be compressed, so that the limit column 70 is separated from the limit groove 303, and the limit of the dial wheel 30 by the limit column 70 is released. Under the action of the elastic force of the elastic element 60, the limiting column 70 can be gently embedded in the limiting groove 303 or separated from the limiting groove 303, and the movement smoothness of the limiting column 70 is greatly improved.

Referring to fig. 6, a schematic distribution diagram of a limiting column according to an embodiment of the present application is shown. In some optional embodiments of the present application, the number of the limiting grooves 303 on the central shaft 306 is multiple, and the multiple limiting grooves 303 are distributed at intervals along the circumference of the central shaft 306; correspondingly, the number of the limiting columns 70 can be multiple, the number of the limiting columns 70 is smaller than or equal to the number of the limiting grooves 303, and the multiple limiting columns 70 are distributed at intervals along the circumferential direction of the central shaft 306; when the thumb wheel 30 is in the locked state, one of the limit posts 70 is embedded in one of the limit grooves 303, so that the reliability of the embedded position of the limit post 70 in the limit groove 303 is improved, and further, the limit reliability of the limit post 70 on the thumb wheel 30 can be improved, and the thumb wheel 30 is prevented from rotating in the locked state.

In the drawings of the embodiments of the present application, only the case where the number of the stopper grooves 303 and the number of the stopper posts 70 are 4 are shown. In practical applications, the number of the spacing grooves 303 and the spacing columns 70 may be other values, for example, 6, 8, or 10. Moreover, the number of the limiting grooves 303 and the number of the limiting posts 70 may not be equal, for example, the number of the limiting grooves 303 may be 8, and the number of the limiting posts 70 may be 6. The number of the limiting columns 70 and the limiting grooves 303 is not particularly limited in the embodiment of the application.

Referring to fig. 7, which shows a structural schematic diagram of a bracket according to an embodiment of the present application, as shown in fig. 7, the bracket 80 is provided with a first through hole 802, and the central shaft 306 extends into the bracket 80 through the first through hole 802; a plurality of assembling columns 801 are arranged in the support 80, the assembling columns 801 are distributed at intervals around the circumference of the first through hole 802, the elastic part 60 is sleeved outside the assembling columns 801, and the limiting column 70 is connected to one end, close to the first through hole 802, of the elastic part 60.

In a specific application, the elastic member 60 is sleeved outside the assembling column 801, so that the movement direction of the elastic member 60 can be limited, and the movement precision of the limiting column 70 connected to the elastic member 60 is improved, and thus, one end of the limiting column 70, which is far away from the elastic member 60, can be conveniently embedded in the limiting groove 303 of the central shaft 306, or can be separated from the limiting groove 303.

Referring to fig. 8, a schematic connection diagram of a limiting mechanism and a central shaft according to an embodiment of the present application is shown. As shown in fig. 8, the position-limiting column 70 may be at least partially embedded in the position-limiting groove 303 of the central shaft 306 under the action of the elastic member 60, so as to achieve the locking state of the thumb wheel 30.

Referring to fig. 9, which shows a schematic structural view of a first housing according to an embodiment of the present disclosure, as shown in fig. 9, an opening a01 of a first housing A0 may be used to guide the movement of the first strap 10 and the second strap 20. The first casing A0 is provided with an assembly groove a03, and the bracket 80 is installed in the assembly groove a 03. As shown in fig. 3, a guide post a02 is further disposed on a side of the first housing A0 away from the thumb wheel 30, a guide groove 305 is further disposed at an end of the central shaft 306 away from the knob 301, the guide post a02 can be embedded in the guide groove 305 and can slide along the guide groove 305, and the guide post a02 can be used for guiding the movement of the central shaft 306, so that the central shaft 306 can only move in the axial direction.

As shown in fig. 7, a plurality of elastic arms 803 are disposed in the bracket 80, and the plurality of elastic arms 803 are spaced around the circumference of the first through hole 802 and at least partially extend into the first through hole 802.

When the thumb wheel 30 is in the locked state shown in fig. 10, the retainer ring 304 and the resilient arm 803 are displaced in the axial direction of the central shaft 306. When the thumb wheel 30 is in the unlocked state shown in fig. 11, the stop collar 304 abuts against the elastic arm 803, so that the thumb wheel 30 maintains the unlocked state. Thus, it is possible to prevent the thumb wheel 30 from being pushed back by a user's mistake during the rotation of the thumb wheel 30 when the first strap 10 and the second strap 20 are not yet adjusted to the proper positions, and thus the thumb wheel 30 is locked again, so as to improve the reliability of the tightness degree of the adjustment of the first strap 10 and the second strap 20 by the thumb wheel 30.

In some optional embodiments of the present application, as shown in fig. 2, the adjusting device 100 may further include: the limiting sheet 90 is connected to one end, far away from the knob 301, of the central shaft 306 and is arranged in the shell; the outer diameter of the spacing piece 90 is larger than the outer diameter of the central shaft 306.
