Description

Technical Field

[0001] The utility model relates to the technical field of shoelaces, in particular to a shoelace with adjustable length. Background Art

[0002] Shoelaces are a tool used to tighten shoes, and when there is a problem with the shoelaces, new shoelaces can be purchased for replacement. However, since the length of the shoelaces and the size of the shoes are prone to deviation, the shoelaces are often too long or too short, which is very inconvenient for people to use;

[0003] In the prior art, for example, announcement number CN217592156U proposes a shoelace with adjustable length. The name of this technical solution is a shoelace with adjustable length, which relates to a shoelace including a shoelace body and a buckle part. The shoelace body is a conventional longer shoelace, and the shoelace has hard parts at both ends. The buckle part is a tubular structure that can be put on the hard parts at both ends of the shoelace, and symmetrical notches are provided on both sides of the tubular structure. The notches can be used to clamp the folded shoelace in a clamping manner to prevent the folded shoelace from unraveling. When the length does not need to be adjusted, the tubular structure is put on the hard parts at both ends, which will not affect the normal use of the shoelace. When the length needs to be adjusted, the tubular structure is removed, and after the shoelace is tied, the excess part can be folded in half and then the notch of the tubular structure is used to put on the folded part, which can play a fixing role and prevent it from unraveling.

[0004] However, the shoelaces of the prior art are fastened by clamping the folded shoelaces through the notch on the tubular structure to prevent the folded shoelaces from spreading out. Since the tubular structure is only fixed to the shoelaces by clamping, the stability of the tubular structure is poor, which makes it easy for the tubular structure to fall off and be lost. Therefore, this shoelace length adjustment method makes the shoelaces less stable when in use.

[0005] In order to solve the above problems, the present application proposes a shoelace with adjustable length. Utility Model Content

[0006] The utility model is intended to provide a shoelace with adjustable length, which is mainly used to solve the problem that the tubular structure on the existing shoelace is only fixed on the shoelace by a clamping method, which causes the tubular structure to fall off and be lost easily, thus affecting the normal use of the shoelace.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A shoelace with adjustable length comprises a shoelace body, both ends of the shoelace body are fixedly connected with fixing heads, a cavity is provided inside the fixing heads, one end of the inner wall of the cavity is fixedly connected with an elastic band, a through groove matching the elastic band is provided on the fixing head, one end of the elastic band extends out of the fixing head and is fixedly connected with an insert block, a slot matching the insert block is provided at one end of the fixing head away from the shoelace body, and a limiting component is provided on the insert block.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When the shoelace is used, since the shoelace itself is a long shoelace, the length will not be insufficient. When the shoelace is too long, the excess shoelace part can be wrapped around the outer wall of the fixed head and positioned above the insert block, and then the insert block is pulled outward to stretch the elastic band from the inside of the cavity to a certain length, and then the insert block is inserted into the slot at one end of the fixed head. The limit assembly on the insert block can better fix the insert block. At this time, the elastic band can fix the excess shoelace body on the outer wall of the fixed head, thereby realizing the adjustment of the shoelace length.

[0011] 2. Beneficial effect: After the shoelaces are tied, the excess shoelaces can be wrapped around the outer wall of the fixed head and positioned above the insert block, and then the insert block is pulled and inserted into the slot on the fixed head. The insert block is fixed in the slot through the limiting component. At this time, the elastic band can better fix the shoelace body wrapped around the outer wall of the fixed head, thereby effectively avoiding inconvenience to the user due to the shoelaces being too long, and can make the shoelaces more stable when in use.

[0012] The cam is secured to the inner wall of the shoe and is provided with a spring which is adapted to engage the cam and to engage with the spring when the shoe is fully inserted into the shoe.

[0013] Preferably, the inner wall of the through groove is rotatably connected with a plurality of ball bearings, and the ball bearings are equidistantly distributed on the inner wall of the through groove in a circular array. The plurality of ball bearings arranged on the inner wall of the through groove can effectively reduce the friction between the elastic band and the inner wall of the through groove when people pull the plug block. This not only makes it easier and more labor-saving for people to pull the plug block, but also effectively reduces the wear of the inner wall of the through groove on the elastic band, thereby effectively extending the service life of the shoelaces.

[0014] Preferably, sliders are fixedly connected to both sides of the button, and the inner wall of the limiting groove is provided with a sliding groove matching the slider. When the button slides inside the limiting groove, the sliders arranged on both sides of the button and the sliding groove provided on the inner wall of the limiting groove can play a better limiting and guiding role for the button, so that the button has higher stability when sliding inside the limiting groove, and can effectively prevent the button from detaching from the limiting groove, thereby effectively ensuring the normal use of the shoelaces.

[0015] Preferably, there are two springs inside the sliding cavity, and the springs are symmetrically arranged inside the sliding cavity. By setting the number of springs inside the sliding cavity to two, the two springs can exert a greater thrust on the wedge block, so that the wedge block can better fix the insert block when it is engaged with the limit groove on the fixed head, thereby further improving the stability of the shoelaces when in use.

[0016] Preferably, the corner of the insert block away from the elastic band is chamfered. By chamfering the corner of the insert block away from the elastic band, it is easier to insert the insert block into the slot, thereby making the shoelaces easier to use.

[0017] Preferably, the outer wall of the plug block is provided with a rubber sleeve, and the outer wall of the rubber sleeve is provided with anti-slip grooves. The rubber sleeve provided on the outer wall of the plug block can make people's hands more comfortable when pinching and pulling the plug block. The anti-slip grooves provided on the rubber sleeve can increase the friction between people's hands and the plug block, thereby effectively preventing people's hands from slipping when pulling the plug block.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 , a shoelace with adjustable length comprises a shoelace body 1. Since the shoelace itself is a shoelace of relatively long length, the shoelace body 1 will not be inadequately long. Both ends of the shoelace body 1 are fixedly connected with a fixing head 2. A cavity 3 is provided inside the fixing head 2. One end of the inner wall of the cavity 3 is fixedly connected with an elastic band 4. A through slot 5 matching the elastic band 4 is provided on the fixing head 2. One end of the elastic band 4 extends out of the fixing head 2 through the through slot 5. A plurality of balls 13 are rotatably connected to the inner wall of the through slot 5, and the balls 13 are equidistantly distributed on the inner wall of the through slot 5 in a circular array. One end of the elastic band 4 extends out of the fixing head 2 and is fixedly connected with an insert block 6. Pulling the insert block 6 can put the elastic band 4 in a stretched state. The plurality of balls 13 provided on the inner wall of the through slot 5 can effectively reduce the friction between the elastic band 4 and the inner wall of the through slot 5 when people pull the insert block 6. This not only makes it easier and more labor-saving for people to pull the insert block 6, but also can effectively The wear of the inner wall of the through groove 5 on the elastic band 4 is reduced, thereby effectively extending the service life of the shoelace. A slot 7 matching the insert block 6 is provided at one end of the fixed head 2 away from the shoelace body 1. The corner of the insert block 6 away from the elastic band 4 is chamfered, which makes it more convenient to insert the insert block 6 into the slot 7. The outer wall of the insert block 6 is sleeved with a rubber sleeve, which makes it more comfortable for people to pinch and pull the insert block 6. The outer wall of the rubber sleeve is provided with anti-skid patterns, which can increase the friction between people's hands and the insert block 6, thereby effectively preventing people from slipping when pulling the insert block 6. A limiting component is provided on the insert block 6, and the insert block 6 is pulled and inserted into the slot 7 on the fixed head 2. The insert block 6 is fixed in the slot 7 by the limiting component. At this time, the elastic band 4 can play a good fixing role on the shoelace body 1 wrapped around the outer wall of the fixed head 2, thereby effectively avoiding inconvenience to the user due to the shoelace being too long, and making the shoelace more stable when in use.

[0025] like Figure 2 and Figure 3As shown, the limiting assembly includes a symmetrical sliding cavity 8 provided on the outer wall of the plug block 6, a wedge block 9 is slidably connected inside the sliding cavity 8, the plug block 6 extends from one side of the wedge block 9, and a symmetrical spring 10 is fixedly connected to the other side, the other end of the spring 10 is fixedly connected to the inner wall of the sliding cavity 8, and a limiting groove 11 matching the wedge block 9 is provided on the inner wall of the slot 7, a button 12 is slidably connected inside the limiting groove 11, a fixed head 2 extends from one side of the button 12, and the other side is set against the wedge block 9. When the plug block 6 is inserted into the slot 7, the wedge block 9 is squeezed and moves into the sliding cavity 8, and at the same time squeezes the spring 10 and puts it in a compressed state. When the plug block 6 is fully inserted into the slot 7, the wedge block 9 will pop out and By engaging with the limiting groove 11 on the fixing head 2, the insert block 6 can be better fixed. At the same time, pressing the two buttons 12 on the fixing head 2 can push the wedge block 9 to move into the sliding cavity 8. After the wedge block 9 is out of the limiting groove 11, the insert block 6 can be pulled out of the slot 7. This not only makes the use of shoelaces more convenient, but also makes the shoelaces more stable when used. Both sides of the button 12 are fixedly connected with sliders 14, and the inner wall of the limiting groove 11 is provided with a sliding groove 15 matching the slider 14, which can better limit and guide the button 12, so that the button 12 has higher stability when sliding inside the limiting groove 11, and can effectively prevent the button 12 from being out of the limiting groove 11, thereby effectively ensuring the normal use of the shoelaces.

[0026] From the above, it can be seen that the specific implementation of the utility model is as follows:

[0027] When the shoelace is in use, since the shoelace itself is a long shoelace, the length will not be insufficient. When the shoelace is too long, the excess shoelace part can be wrapped around the outer wall of the fixed head 2 and positioned above the inserting block 6, and then the inserting block 6 is pulled outward to stretch the elastic band 4 from the cavity 3 to a certain length, and then the inserting block 6 is inserted into the slot 7 at one end of the fixed head 2. During the insertion of the inserting block 6 into the slot 7, the wedge block 9 is squeezed and moves into the sliding cavity 8, and at the same time, the spring 10 is squeezed and compressed. When the inserting block 6 is fully inserted into the slot 7, the wedge block 9 will pop out under the action of the spring 10 and engage with the limiting groove 11 on the fixed head 2, which can play a better fixing effect on the inserting block 6. At the same time, pressing the two buttons 12 on the fixed head 2 can push the wedge block 9 to move into the sliding cavity 8. After the wedge block 9 is separated from the limiting groove 11, the inserting block 6 can be pulled to separate from the slot 7, which not only makes the use of the shoelace more convenient, but also makes the shoelace more stable when in use.
