[0054] As Figure 6 and Figure 7As shown, the locking assembly 6 further comprises a locking box 61 connected with the shell 51, a second tension spring 64 and a locking knob 65, the ratchet 62 and the stop pawl 63 are both pivoted in the locking box 61, the end of the rotating shaft 57 passes through the locking box 61 after passing through the shell 51 so as to be connected with the ratchet 62 and the locking knob 65, the locking knob 65 is located outside the locking box 61, the ratchet 62 is located in the locking box 61, the stop pawl 63 can abut on the ratchet 62 so as to lock the ratchet 62, the ratchet 62 is connected with the rotating shaft 57, and the ratchet 62 and the rotating shaft 57 can be linked together; the second tension spring 64 is connected between the locking box 61 and the stop pawl 63, the elastic action of the second tension spring 64 can make the stop pawl 63 abut on the ratchet 62 tightly without external force, so that the ratchet 62 is always kept in the locked state, the ratchet 62 is connected with the rotating shaft 57, and thus the whole adjusting assembly 5 is kept in the fixed state, that is, the shoelace 4 is tightly connected between the upper 2 and the adjusting assembly 5.

[0055] As shown in the figure, Figure 8 The driving assembly 7 comprises a second rack 72, a sector gear 76, a compression spring 75 and a button 711, the second rack 72 is slidingly arranged on the locking box 61, the top of the second rack 72 is connected with a guide shaft 71, the guide shaft 71 is slidingly matched with the locking box 61 so as to increase the stability of the movement of the second rack 72; the sector gear 76 is coaxially and fixedly installed with the stop pawl 63, and is meshingly connected on one side of the second rack 72; the compression spring 75 is connected between the second rack 72 and the locking box 61; the top of the guide shaft 71 is threadedly connected with the button 711 for easy operation, and the button 711 is located above the locking box 61.

[0056] Preferably, the side of the second rack 72 away from the sector gear 76 is connected with a guide block 73, the lower side of the guide block 73 is connected with a convex column 74, the top of the compression spring 75 is sleeved on the convex column 74, and the compression spring 75 is guided and limited by the convex column 74, so that the compression spring 75 is more stable when being compressed and reset.

[0057] Preferably, the locking box 61 is provided with a containing cavity 66 and a guide hole 68, the containing cavity 66 is used for installing and containing the compression spring 75, and the guide hole 68 is used for guiding the guide shaft 71 so as to make the movement of the driving assembly 7 more stable. In addition, since the guide block 73 moves vertically, the containing cavity 66 is provided with a side opening 67 allowing the vertical movement of the guide block 73.

[0058] In the embodiment of the application, since the rotating shaft 57 is connected with the driving gear 55, the ratchet wheel 62 and the locking knob 65, and the rotation of the ratchet wheel 62 needs the driving assembly 7 to drive the stop pawl 63 to rotate, the loosening of the shoelace 4 needs to use the driving assembly 7, and when the driving assembly 7 is not operated, the locking knob 65, the ratchet wheel 62 and the driving gear 55 rotate counterclockwise, and the tightening of the shoelace 4 can be achieved.

[0059] Specifically, the locking knob 65 is counterclockwise rotated first, the pawl head of the stop pawl 63 is separated from the tooth groove of the ratchet wheel 62, then the button 711 is pressed downward, the guide shaft 71 drives the second rack 72 to move downward, the compression spring 75 is compressed, and the sector gear 76 drives the stop pawl 63 to rotate clockwise, the pawl head is completely separated from the tooth groove, the stop pawl 63 is released from the ratchet wheel 62, and since the stop pawl 63 rotates clockwise, the second tension spring 64 is elongated, when the stop pawl 63 is released from the ratchet wheel 62, the clockwise operation of the locking knob 65 can drive the ratchet wheel 62 to rotate clockwise, the rotating shaft 57 is driven to rotate clockwise, the moving assembly drives the lock 53 to move upward, and the shoelace 4 is quickly loosened, in addition, the counterclockwise operation of the locking knob 65 can drive the ratchet wheel 62 to rotate counterclockwise, the rotating shaft 57 is driven to rotate counterclockwise, the moving assembly drives the lock 53 to move downward, and the shoelace 4 is quickly tightened, after the shoelace 4 is quickly tightened, the button 711 is released, the compression spring 75 and the second tension spring 64 are reset, the stop pawl 63 is reset and abuts on the tooth groove of the ratchet wheel 62, the ratchet wheel 62 is prevented from rotating counterclockwise, then when the shoelace is tightened, the locking knob 65 is counterclockwise rotated, the ratchet wheel 62 drives the rotating shaft 57 to rotate counterclockwise, the moving assembly drives the lock 53 to move downward, and the shoelace 4 is further tightened.

[0060] Working principle: before wearing the shoes, operate the locking knob 65 counterclockwise, so that the stop pawl 63 releases the resistance to the ratchet 62, then operate the drive assembly 7, so that the stop pawl 63 is separated from the ratchet 62, then rotate the locking knob 65 clockwise, so that the lock 53 moves up and resets, so that the shoelace 4 is loosened, then release the button 711, under the reset action of the compression spring 75 and the second tension spring 64, the second rack 72 will move up and reset, the second rack 72 will drive the sector gear 76 to rotate counterclockwise, and the sector gear 76 is coaxially connected with the stop pawl 63, so the stop pawl 63 will also rotate counterclockwise, so that the stop pawl 63 will again resist the tooth groove of the ratchet 62, and the ratchet 62 is locked again, then wear the shoes, rotate the locking knob 65 counterclockwise, so that the lock 53 moves down, so that the shoelace 4 can be tightened, when you need to further tighten the shoelace 4, continue to rotate the locking knob 65 counterclockwise. After locking, the locking assembly 6 is in a locked state, so even if the movement amplitude is large, it will not cause the shoelace 4 to loosen, ensuring the tightness of the shoes and the feet, and by limiting the two ends of the shoelace 4 in the lock 53, the ends of the shoelace 4 are avoided from being exposed, and the situation of stepping on the shoelace 4 is avoided, ensuring the safety of use.

[0061] In summary, the present application can fix the ends of the shoelace 4 through the adjusting assembly 5, and can adjust the tightness of the shoelace 4 through the locking assembly 6, so it has the characteristics of convenient use and high safety.

[0062] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the embodiments of the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
