Referring to fig. 1 to 4, an embodiment of the invention provides an escape rotation control clutch, which includes an upper cover 10, a control assembly 20, a spool 30 and a base 40, wherein the upper cover 10 is fixedly provided with a control member 11, and when the upper cover 10 is rotated, the control member 11 can be driven to move.

The control assembly 20 includes a control claw 21 and a control panel 22, the control claw 21 is rotatably installed on the upper surface of the control panel 22, and the control claw 21 can be pushed to rotate a certain angle by the control member 11 on the upper cover 10. The control disc 22 is provided with a first engagement formation 23 at its periphery.

The spool 30 includes a control portion 31 and a winding portion 32 for winding the rope. The control unit 31 is located at the upper portion of the bobbin 30, and the winding unit 32 is located at the lower portion of the bobbin 30. The control panel 22 has a hollow structure in the middle, and the control portion 31 of the spool 30 passes through the middle of the control panel 22 during assembly so that the control claw 21 and the control portion 31 can be engaged with each other.

The upper cover 10 and the base 40 enclose an accommodating space, and the control assembly 20 and the spool 30 are disposed in the accommodating space. The upper portion of the base 40 is provided with a second engagement structure 421, and the first engagement structure 23 is unidirectionally engaged with the second engagement structure 421 so that the control assembly 20 can be rotated only unidirectionally along the base 40, but not reversely.

The control claw 21 has two opposite ends (as shown in fig. 5), one is an engagement portion 211, the other is a disengagement portion 212, and the upper cover 10 rotates the control member 11 through rotation, so that the control member 11 abuts against any end of the control claw 21 to switch the use state of the escape rotation control clutch. The use states of the escapement rotation control clutch include a rope releasing state and a rope tightening state.

Referring to fig. 6, when the control member 11 abuts against the engagement portion 211, the control member 11 engages with the control portion 31, so that the control member 11 is linked with the spool 30. At this time, the state of use of the escapement rotation control clutch is a rope tightening state, and in this state, the rope tightening effect can be achieved by continuously rotating the upper cover 10 in one direction.

Referring to fig. 7, when the control member 11 abuts against the disengaging portion 212, the control member 11 is separated from the control portion 31, so that the control member 11 is disengaged from the spool 30, and the spool 30 can rotate freely. At this time, the use state of the escapement rotation control clutch is a rope releasing state, and in this state, the spool 30 can be driven to rotate by pulling the rope, thereby achieving the effect of releasing the rope.

The embodiment of the invention switches the use state of the escapement rotation control clutch by rotating the upper cover 10 forward or backward to switch whether the control member 11 in the control assembly 20 is linked with the spool 30.

Specifically, with continued reference to fig. 2 and 3, the control portion 31 is gear-shaped, the disengaging portion 212 of the control pawl 21 is provided with a latch, and when the control member 11 abuts against the engaging portion 211, the control pawl 21 is pushed to rotate by a certain angle, and finally the latch is snapped onto the control portion 31 (as shown in fig. 6), so that the spool 30 is restricted from rotating.

Taking the present embodiment as an example, the user rotates the upper cover 10 counterclockwise, so that the control member 11 abuts against the engagement portion 211 and drives the latch on the disengaging portion 212 of the control pawl 21 to be locked on the control portion 31 on the spool 30. The upper cover 10 is continuously rotated anticlockwise, and the control member 11 drives the spool 30 to rotate anticlockwise so as to finish rope collection. When the rope is taken up to a proper tightness, the user releases the upper cover 11, and the current tightness can be maintained.

When the control member 11 abuts against the disengaging portion 212, the control member 21 is pushed to rotate a certain angle, so that the latch is separated from the control portion 31 (as shown in fig. 7), the spool 30 loses control of the control pawl 21, and the rope is released by pulling the rope.

Taking this embodiment as an example, the user rotates the upper cover 10 clockwise, so that the control member 11 abuts against the disengaging portion 212, and pushes the control member 21 to rotate, so that the latch is disengaged from the control portion 31, and at this time, the rope outside the capturing rotation control clutch is pulled, so that rope loosening can be achieved.

Specifically, the control member 11 is identical in number to the control pawls 21, so that each control pawl 21 is controlled by the control member 11, making the construction of the pull-on, release-rotation control clutch more stable.

Specifically, the first engagement structure 23 is a pawl, and the second engagement structure 421 includes a plurality of teeth disposed circumferentially along an inner wall of the base 40 to form a ring gear within which the pawl moves unidirectionally. It should be noted that the second engagement structure 421 is a wedge structure, and when the first engagement structure 23 and the second engagement structure are engaged with each other, the control panel 22 can only rotate unidirectionally, but cannot rotate reversely.

Specifically, a limiting member 24 is further provided on the periphery of the control panel 22, and the limiting member 24 is disposed adjacent to the control claw 21 to limit the rotation angle of the control claw 21 and prevent the control claw 21 from over-rotating.

More specifically, two stoppers 24 are provided, and the two stoppers 24 are provided opposite to each other. The first engagement structures 23 are provided in two, and the two first engagement structures 23 are disposed opposite to each other. The limiting member 24 and the first engagement structure 23 are both disposed on the periphery of the control disc 22, but not on the same side.

Specifically, the middle part of upper cover 10 still is provided with buckle 12, and the middle part of spool 30 is provided with the buckle passageway 33 that supplies buckle 12 to pass, and buckle passageway 33 inside is provided with the block 331 that supplies buckle 12 joint. When the catching and releasing rotation control clutch is assembled, the clamping buckle 12 of the upper cover 10 is clamped on the clamping table 331 of the spool 30, so that the assembly is convenient and quick, and time and labor are saved.

Specifically, the base 40 includes a base 41 and a cylinder 42 mounted on the base 41, and a first rope hole 422 for passing a rope is provided on the cylinder 42. In actual use, the seat 41 is secured to a wearable article, such as shoes, pants, etc., to enable the escapement rotation control clutch to assist in tightening or releasing the cord.

The bottom of barrel 42 is provided with fastener 423, is provided with the bayonet socket 411 that supplies fastener 423 joint on the pedestal 41, and at the in-process of equipment, barrel 42 can install on pedestal 41 fast, equipment convenient and fast.

The winding portion 32 of the bobbin 30 is provided with a second rope hole 34 through which the rope body passes. The spool 30 is hollow, and in the practical use process, two free ends of the rope body can penetrate into the hollow structure of the spool 30 from the second rope hole 34, and the free ends of the rope are stored in the hollow structure after knotted.

It will be appreciated that the control plate 22 of the escapement rotation control clutch is provided with a first engagement structure 23 and the upper portion of the base 40 is provided with a second engagement structure 421, the first engagement structure 23 being unidirectionally engaged with the second engagement structure 421 so that the control assembly 20 can only rotate unidirectionally along the base 40 and cannot rotate reversely. The purpose of rope tightening or rope releasing is achieved by controlling whether the spool 30 is linked with the control assembly 20, and when the spool 30 is linked with the control assembly 20, the spool 30 is limited by unidirectional engagement of the first engagement structure 23 and the second engagement structure 421; when the spool 30 is not in linkage with the control assembly 20, the spool 30 is in a free state. When the user rotates the upper cover 10, the control member 11 is abutted against the engagement portion 211 of the control claw 21, so that the latch on the disengagement portion 212 of the control claw 21 is driven to be clamped on the control portion 31 on the spool 30, and the rope is wound up by continuously rotating the upper cover. When the rope is taken up to a proper tightness, the user releases the upper cover 11, and the current tightness can be maintained. The control assembly 20 should maintain consistency with the direction of rotation of the upper cover 10 only in the direction of unidirectional rotation of the base 40. When the user rotates the upper cover 10 reversely, the control member 11 is abutted against the disengaging portion 212 of the control claw 21, the control member 21 is pushed to rotate, so that the latch is disengaged from the control portion 31, and the rope outside the escapement rotation control clutch is pulled at this time, so that rope loosening can be realized.

The escapement rotation control clutch provided by the embodiment of the invention has the beneficial effects that: by rotating the upper cover 10 forward or backward to switch whether the control member 11 of the control assembly 20 is linked with the spool 30, the use state of the escape rotation control clutch is switched, and the rope tightening or rope loosening can be rapidly realized.

In the above-described embodiments, the escape rotation control clutch is used on a wearable article requiring a tether, such as footwear, medical protective equipment, or the like. Preferably, the escapement rotation control clutch is used on a shoe for adjusting the tightness of the shoe cord.

In the present embodiment, the counterclockwise direction is assumed to be the rope tightening direction, but is not limited thereto. In other embodiments, since the habit of using the left and right hands of the person is different, the clockwise direction may be the rope tightening direction, and only the unidirectional engagement direction of the first engagement structure 23 and the second engagement structure 421 and the gear direction of the control claw 21 and the control portion 31 are required to be changed, and other principles are the same as those of the present embodiment and are not described herein.

The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
