Set up and cover drum 8, can make spacingly to the shoelace of winding on line wheel 2, avoid the shoelace to deviate from line wheel 2, realization lacing and the pine shoelace that can be better.

The rotary disc 3 is provided with a plug-in groove 33 for the plug-in positioning of the reset spring 6. The rotary disc 3 is additionally provided with the inserting groove 33, so that the reset spring 6 can be conveniently installed and positioned.

The rotary disc 3 is further provided with a check ring 34, a plurality of groups of barbs 35 are arranged on the periphery of the check ring 34, the check piece 7 is provided with 3 groups of elastic hooks 71, and the end parts of the elastic hooks 71 are abutted to the periphery of the check ring 34. Rationally arrange the direction of barb 35 for when carousel 3 turned to along effective lacing to rotate, elastic hook 71 can slide in end contrary 34 peripheries, and the conflict action can not take place for barb 35 and elastic hook 71, in case carousel 3 produces when the contra-rotation state, elastic hook 71 can and take place the conflict action between barb 35, impels carousel 3 can not the contra-rotation, makes the shoelace keep tying the state.

Be equipped with shoelace and wear piece 9 on base 1, through wires hole 11 distributes on shoelace wears piece 9, shoelace wears the material of piece 9 and is soft material. The shoelace threading piece 9 made of soft materials is arranged, so that shoelaces can be prevented from being scratched; wherein, the soft material can be selected from rubber, TPU and TPR.

The upper part of the rotary table 3 is detachably connected with a decorative cover 10 made of transparent materials. The decorative cover 10 is transparent, and the decorative pattern can be arranged on the lower end face of the decorative cover 10, so that the decorative pattern is prevented from being worn out after the decorative cover 10 is rubbed by hands for a long time.

Example two: as shown in fig. 4 to 7 and 10 to 14, compared with the first embodiment, the second embodiment does not need to install the shoelace threading member 9, and the bottom of the reel 2 of the second embodiment is provided with 8 groups of winding holes 21, and every 4 groups of winding holes 21 are provided with criss-cross winding channels 22; otherwise, the remaining components are identical to those of the first embodiment. As shown in fig. 14, the 4 groups of winding holes 21 are respectively a first winding hole 211, a second winding hole 212, a third winding hole 213 and a fourth winding hole 214, the steel-wire shoelace rope can be threaded into the first winding hole 211, wound to the second winding hole 212 along the winding channel 22, then discharged from the second winding hole 212, then fed from the third winding hole 213, and finally discharged from the fourth winding hole 214 along the winding channel 22 to the fourth winding hole 214, and winding can be completed without knotting.

Compared with the existing shoelace buckle, the shoelace loosening device has the advantages that the shoelace loosening device does not need to rotate the rotary disc 3, the shoelace loosening can be realized in seconds after being pressed, the operation is convenient, parts are rare, the cost is greatly reduced, the design difficulty of the corresponding die is reduced, the volume of the shoelace buckle is small, and the appearance of the vamp cannot be influenced.

The working principle is as follows: the working principle of the first embodiment is the same as that of the second embodiment, when the shoelace is tied, the rotary disc 3 is directly rotated, the rotary disc 3 drives the inner lock gear 4 to rotate through the outer gear ring 41 and the inner gear ring 32, and the inner lock gear 4 drives the reel 2 to rotate so as to tie the shoelace; when loosening the shoelace, press down carousel 3, until outer ring gear 41 breaks away from ring gear 32, the two is not in the meshing transmission, and the staff pulling shoelace this moment, line wheel 2 can reverse rotation, realizes the function of untiing the shoelace for the second, and the back is loose to the shoelace, and the staff releases carousel 3, and reset spring 6 pops up carousel 3 and resets.
