DETAILED DESCRIPTION

[0024] The embodiments of the utility model are explained below in combination with the drawings.

[0025] Embodiment one

[0026] As shown in Figure 1 , Figure 2 , the embodiment realizes the surrounding elastic shoelace tightening structure through rotary shoelace buckle 5, sets up two passageways 3 on shoe body 1, one of the passageways 3 is from the inner side of shoe body 1 to the back of shoe body 1 and extends to the outer side of shoe body 1, and the other passageway 3 is from the outer side of shoe body 1 to the back of shoe body 1 and extends to the inner side of shoe body 1, and two passageways 3 respectively extend to the opposite side of shoe body 1 from the two sides of shoe body 1, and elastic band 4 is respectively threaded in two passageways 3, so that elastic band 4 also extends to the opposite side of shoe body 1 from the one side of shoe body 1, thereby forming the surrounding elastic shoelace.

[0027] In this embodiment, a rotating shoelace buckle 5 is provided on the shoe tongue 2. Two pull ropes 6 are coiled inside the rotating shoelace buckle 5. The ends of the two pull ropes 6 extend outward from inside the rotating shoelace buckle 5, and the exposed ends of the two pull ropes 6 are located on both sides of the shoe body 1. The rotating shoelace buckle 5 is the prior art. By rotating the knob of the rotating shoelace buckle 5, the two pull ropes 6 can be rolled into the rotating shoelace buckle 5. By lifting the knob, it can be unlocked, and after unlocking, the pull ropes 6 can be pulled out.

[0028] One end of each of the two elastic bands 4 is connected to the exposed end of the pull cord 6 on the corresponding side, and the other end of each of the two elastic bands 4 is connected to the front of the shoe body 1.

[0029] By rotating the shoelace buckle 5 to tighten the shoelaces, the two elastic bands 4 are tightened. Under the tension of the elastic bands 4, the rotating shoelace buckle 5 is pressed onto the tongue 2, thereby further pressing the tongue 2 onto the instep. On the other hand, the rear of the shoe body 1 is pressed forward, thereby pressing the rear of the shoe body 1 onto the heel and the back of the ankle, so that the rear part of the shoe body 1 covers the heel, thus fixing the shoe on the foot. This effectively prevents gaps between the rear of the shoe body 1 and the heel, avoiding problems such as the foot sliding back and forth inside the shoe body 1 or the shoe not fitting properly when walking or running.

[0030] After unlocking, the pull cord 6 extends, and the two elastic bands 4 retract and reset, thereby loosening the shoe tongue 2, making it easy to take off the shoe.

[0031] In this design, two channels 3 on the shoe body 1 are arranged one above the other, and the two channels 3 are parallel to each other at the rear of the shoe body 1. In this way, two elastic bands 4 are distributed parallel to each other at the rear of the shoe body 1. The material at the rear of the shoe body 1 is adapted to the shape of the heel by the two elastic bands 4, which increases the coverage and comfort.

[0032] Furthermore, the ends of the two elastic bands 4 that are not connected to the pull cord 6 are respectively connected to the two sides of the shoe tongue 2. In this way, the shoe tongue 2 is not only pressed tightly against the foot by the downward pressure of the rotating shoelace buckle 5, but also pressed tightly against the foot by the pulling force of the two elastic bands 4.

[0033] Furthermore, such as Figure 5 As shown, a highly elastic layer 7 can be provided on the shoe tongue 2. The highly elastic layer 7 can be the outer layer, inner layer, or middle layer of the shoe tongue 2. Two elastic bands 4 are connected to both sides of the highly elastic layer 7. By tightening the highly elastic layer 7 through the elastic bands 4, the shoe tongue 2 is tightened and made to fit snugly against the foot. The highly elastic layer 7 can be a mesh structure or fabric made of highly elastic material, which can increase comfort.

[0034] Among them, channel 3 can be located inside the structure of shoe body 1, specifically in the interlayer of shoe body 1 material.

[0035] One end of the channel 3 is located on the surface of the material of the shoe body 1, and the pull rope 6 extends into the channel 3 from the port and is connected with the end of the elastic band 4 in the channel 3. A ring or the like structure can be arranged at the port of the channel 3. On the one hand, the ring can be used as a wear-resistant material for the port to prevent the frequent movement of the pull rope 6 from wearing the material of the shoe body 1. On the other hand, the ring can be used as a limiting structure for the elastic band 4. The inner diameter of the ring is smaller than the size of the elastic band 4. When the pull rope 6 is wound, the end of the elastic band 4 cannot be pulled out of the channel 3 through the ring.

[0036] Embodiment two

[0037] As shown in Figure 3 , Figure 4 , the present embodiment realizes the surrounding elastic shoelace tightening structure through a pulling type structure. Two channels 3 are arranged on the shoe body 1. One of the channels 3 extends from the inner side of the shoe body 1, passes through the rear part of the shoe body 1, and extends to the outer side of the shoe body 1. The other channel 3 extends from the outer side of the shoe body 1, passes through the rear part of the shoe body 1, and extends to the inner side of the shoe body 1. That is, the two channels 3 respectively extend from the two sides of the shoe body 1, pass through the rear part of the shoe body 1, and extend to the opposite sides of the shoe body 1. The elastic bands 4 are respectively arranged in the two channels 3. In this way, the elastic bands 4 also extend from one side of the shoe body 1, pass through the rear part of the shoe body 1, and extend to the opposite side of the shoe body 1, thereby forming a surrounding elastic shoelace.

[0038] One end of each of the two elastic bands 4 is connected to the two sides of the tongue 2, and the other end of each of the two elastic bands 4 is connected with a clasp 8 after passing through the rear part of the shoe body 1.

Under the action of the tension of the elastic bands 4, on the one hand, the tongue 2 is pressed tightly on the instep, and on the other hand, the rear part of the shoe body 1 is pressed forward, thereby pressing the rear part of the shoe body 1 on the heel and the rear part of the instep, so that the rear part of the shoe body 1 is wrapped around the heel, thereby fixing the shoe on the foot, and effectively avoiding the gap between the rear part of the shoe body 1 and the heel, thereby avoiding the problem of the foot sliding forward and backward in the shoe body 1 or the shoe not following the foot during walking or running.

[0041] Meanwhile, when pulling the pulling part 10, the first elastic rope 12 and the second elastic rope 14 are stretched, so that the first elastic rope 12 and the second elastic rope 14 are in a stretched state. When the pulling part 10 is released, the two elastic belts 4 cannot be reset due to the insertion of the plug 8 into the socket 9, but the first elastic rope 12 and the second elastic rope 14 can be reset, so that the pulling part 10 is reset.

[0042] When it is necessary to unlock, the plug 8 is separated from the socket 9, the two elastic belts 4 are reset, so that the tongue 2 is released, and the shoe can be easily taken off.

[0043] The two channels 3 on the shoe body 1 are arranged one above the other, and the two channels 3 are parallel to each other at the rear part of the shoe body 1. In this way, the two elastic belts 4 are distributed in parallel on the rear part of the shoe body 1, and the material of the rear part of the shoe body 1 is adapted to the shape of the heel through the two elastic belts 4, thereby increasing the coverage and comfort.

[0044] The channel 3 can be located inside the structure of the shoe body 1, and can be provided in the interlayer of the material of the shoe body 1.

[0045] Further, as shown in Figure 5 , a high-elasticity layer 7 can be provided on the tongue 2. The high-elasticity layer 7 can be an outer layer, an inner layer, or an intermediate layer of the tongue 2, and the two elastic belts 4 are connected to the two sides of the high-elasticity layer 7. The high-elasticity layer 7 is tightened by the elastic belts 4, so that the tongue 2 is tightened and adheres to the instep. The high-elasticity layer 7 can be a mesh structure or cloth made of high-elasticity material, which can increase the comfort.

[0046] The first elastic rope 12 and the second elastic rope 14 are respectively threaded in the corresponding channels 3.

[0047] As shown in Figure 6 , the socket 9 includes a body box 9-1, an insertion port 9-2 is provided at one end of the body box 9-1, a guide hole 9-3 is provided at the other end of the socket 9, and an unlocking slot 9-4 is provided at both sides of the body box 9-1. The plug 8 includes a main body frame 8-1, elastic arms 8-2 are respectively provided at both sides of the main body frame 8-1, and a clamping part 8-3 is provided at the front end of the outside of the elastic arm 8-2.
