Description
Technical Field
[0001] This application relates to the technical field of footwear, and in particular to a protective shoe with anti-loosening function. Background Technology
[0002] Protective footwear is footwear worn on the feet of users to protect foot safety and prevent foot injuries. Depending on the actual working environment and needs, it can be divided into anti-impact shoes, acid-resistant shoes, heat-resistant shoes, oil-resistant shoes, waterproof rubber shoes, cloth-upper rubber shoes, and soft-soled rubber shoes, etc. The selection of protective footwear should be based on the hazardous nature and degree of harm of the working environment.
[0003] In related technologies, protective shoes generally include a sole, an upper attached to the sole, and shoelaces threaded onto the upper. The upper has an opening for the user's foot to enter and a drawstring opening connected to the opening. The shoelaces are alternately threaded on both sides of the drawstring opening on the upper. When using protective shoes, the upper can be made to fit snugly against the user's foot by tightening the shoelaces.
[0004] However, when wearing these protective shoes, the upper only fits the user's foot by tightening the shoelaces. Once the shoelaces come loose, the shoes can easily slip off the feet, which needs improvement. Utility Model Content
[0005] To enhance stability when worn, this application provides a protective shoe with an anti-loosening function.
[0006] The protective shoe with anti-loosening function provided in this application adopts the following technical solution:
[0007] A protective shoe with anti-loosening function includes a sole, an upper disposed on the sole, and shoelaces threaded on the upper. The upper has an opening for the user's foot to enter and a retractable opening communicating with the opening. The shoelaces are alternately threaded on the upper on both sides of the retractable opening. The upper is provided with several adjustment components, each including a fixing strap, a connecting ring disposed on the fixing strap, and a positioning strap threaded in the connecting ring. The positioning strap includes a fixed section fixedly connected to the upper and a movable section that can move relative to the upper. The fixed section and the movable section are detachably connected by an interlocking component. One end of the fixing strap is connected to the upper, and the other end can move relative to the upper. The end of the fixing strap connected to the upper is located on both sides of the retractable opening, separate from the fixed section.
[0008] By adopting the above technical solution, the protective shoes of this application, when worn, not only ensure the upper fits the user's foot by tightening the shoelaces, but also allow the movable section to pass through the connecting ring and connect to the fixed section to further tighten the opening, thereby making the upper fit the foot more tightly. When the shoelaces accidentally come loose, the adjustment component can further prevent the upper from separating from the foot, providing a secure fit and preventing the shoes from slipping off.
[0009] Optionally, the interlocking component includes a hook and loop male piece and a hook and loop female piece that are bonded together, wherein the hook and loop male piece is fixedly connected to the movable section and the hook and loop female piece is fixedly connected to the fixed section.
[0010] By adopting the above technical solution, after the positioning strap passes through the connecting ring, the male Velcro piece can be pasted onto the female Velcro piece, so that the movable section and the fixed section overlap and adhere together, thereby making the fixing strap tightly fit the shoe upper. When the shoelaces come loose accidentally, the fixing strap can prevent the user's foot from separating from the shoe upper, thus having an anti-loosening effect. In this application, the movable section and the fixed section are attached by Velcro, which is convenient for disassembly and removal, and facilitates the putting on and taking off of protective shoes.
[0011] In addition, users can adjust the bonding position of the male and female Velcro pieces to change the connection length between the movable and fixed sections, thereby adjusting the degree to which the fixing strap closes the upper to accommodate users with different foot sizes.
[0012] Optionally, the interlocking component includes an interlocking male buckle and an interlocking female buckle that engage with each other, wherein the interlocking male buckle is fixedly connected to the movable section and the interlocking female buckle is fixedly connected to the fixed section.
[0013] By adopting the above technical solution, after the positioning belt passes through the connecting ring, the interlocking male buckle and the interlocking female buckle can be engaged with each other, so that the moving section and the fixed section are connected together, which has the characteristics of high connection strength and convenient assembly and disassembly.
[0014] Optionally, the end of the fixing strap away from its connection with the shoe upper has a perforation, and the connecting ring passes through the perforation.
[0015] By adopting the above technical solution, compared with the traditional method of fixing the connecting ring to the fixed belt, the connecting ring is inserted into the hole, which allows the connecting ring to move relative to the fixed belt, so that the positioning belt can be inserted from different directions, making the operation flexible.
[0016] Optionally, the end of the fixing strap away from the connecting ring is provided with a fixing hole, and the shoe surface is provided with a fixing button that cooperates with the fixing hole.
[0017] By adopting the above technical solution, the fixing button and the fixing hole cooperate with each other, so that the fixing strap can be detachably connected to the shoe upper. Compared with the method of sewing the fixing strap to the shoe upper, the fixing strap in this application can be separated from the shoe upper, which makes it easy to replace different styles of fixing straps according to decorative needs, making the style of the fixing strap flexible and varied.
[0018] Optionally, the connecting ring includes a first half-ring and a second half-ring that are magnetically attracted, and the positioning band passes through the connecting hole formed by the first half-ring and the second half-ring.
[0019] By adopting the above technical solution, the first half-ring and the second half-ring are connected by magnetic attraction, which allows the connecting ring to be removed from the hole so that the worn connecting ring can be replaced separately. Furthermore, when only the fixing belt needs to be replaced, the connecting ring does not need to be replaced as well, thereby saving replacement costs.
[0020] Optionally, a stop block is provided on the side of the first half ring near the second half ring, and a stop groove is provided on the second half ring to engage with the stop block.
[0021] By adopting the above technical solution, the first half-ring and the second half-ring are not only connected by magnetic attraction, but also by a stop block and a stop groove, resulting in high connection stability.
[0022] Optionally, the shoe upper has several through holes for shoelaces to pass through, the through holes being located on both sides of the contraction opening and each hole wall having a hard ring.
[0023] By adopting the above technical solution, when the shoelaces are threaded through the through holes, the through holes are not deformed by the tension generated when the shoelaces are tightened because the through holes are equipped with hard rings. This extends the service life of the protective shoes.
[0024] Optionally, the sole is provided with an anti-slip layer underneath, and the bottom of the anti-slip layer is provided with a plurality of anti-slip grooves.
[0025] By adopting the above technical solution, the anti-slip groove increases the friction between the sole and the ground. When wearing protective shoes in the rain, users are less likely to slip and fall due to wet soles, thus reducing the risk of accidental falls and injuries.
[0026] Optionally, a pull tab is provided on the rear side of the shoe upper.
[0027] By adopting the above technical solution, when the user's foot is inserted into the shoe cavity formed by the sole and the upper through the slip opening during the wearing of protective shoes, the user's foot can be inserted into the shoe more quickly by pulling the lifting ring upwards, which is convenient and fast.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. In addition to using shoelaces to make the shoe upper fit the foot, an adjustable component can also be used to prevent the shoe upper from separating from the foot, making the protective shoes less likely to slip off when worn;
[0030] 2. The fixing strap is detachably connected to the shoe upper via fixing buttons and fixing holes, allowing the fixing strap to be replaced, with flexible and varied styles and rich decorative effects;
[0031] 3. The connecting ring consists of a first half-ring and a second half-ring that are magnetically attracted, which facilitates easy individual replacement. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0041] This application discloses a protective shoe with an anti-loosening function.
[0042] Example 1
[0043] Reference Figure 1 A protective shoe with anti-loosening function includes a sole 1, an upper 2 disposed on the sole 1, and shoelaces 3 threaded onto the upper 2. The sole 1 and the upper 2 form a shoe cavity for accommodating the user's foot. An opening 21 communicating with the shoe cavity is provided on the upper 2, allowing the user's foot to be inserted into the shoe cavity through the opening 21 when putting on the shoe. An anti-slip layer 11 is provided below the sole 1, and the bottom of the anti-slip layer 11 has several anti-slip grooves 111. The anti-slip grooves 111 increase the friction between the sole 1 and the ground, making the protective shoe more stable when worn.
[0044] Reference Figure 1 A lifting ring 4 is fixed on the upper back side of the shoe upper 2. When wearing protective shoes, the foot can be quickly put into the shoe cavity by pulling the lifting ring 4. When multiple pairs of shoes need to be taken at once, the lifting ring 4 of multiple pairs of shoes can be lifted directly for easy access.
[0045] Reference Figure 1 Furthermore, to facilitate the user's putting on and taking off of the shoes, a contraction opening 22 communicating with the putting-on opening 21 is provided on the shoe upper 2. Multiple through holes 221 are respectively opened on both sides of the contraction opening 22 on the shoe upper 2. The through holes 221 are preferably circular. A hard ring 222 is fixed to the wall of each through hole 221. The surface of the hard ring 222 is smooth. In this embodiment, the material of the hard ring 222 is preferably plastic. The shoelaces 3 are alternately threaded through the hard rings 222 on both sides of the contraction opening 22. The hard rings 222 can protect the through holes 221 from deformation, extending the service life of the protective shoes. In practical applications, to prevent dust from entering the shoe cavity along the contraction opening 22, a shoe tongue (not shown in the figure) is generally connected to the shoe upper 2 to cover the contraction opening 22.
[0046] Reference Figure 1 In order to improve the stability of the protective shoes when worn, several adjustment components 5 are provided on the upper 2. In this embodiment, one set of adjustment components 5 is provided to illustrate its structure. In other embodiments, the adjustment components 5 can also be set to two sets, three sets, or other quantities.
[0047] Reference Figure 2 and Figure 3 The adjustment component 5 includes a fixing strap 51, a connecting ring 52 disposed on the fixing strap 51, and a positioning strap 53 passing through the connecting ring 52. The positioning strap 53 includes a fixing section 531 fixedly connected to the upper 2 and a movable section 532 that can move relative to the upper 2. The fixing section 531 and the movable section 532 are detachably connected by an interlocking member 54.
[0048] Reference Figure 1One end of the fixing strap 51 is sewn onto the upper 2, while the other end is movable relative to the upper 2. The fixing strap 51 and the fixing section 531 are respectively located on both sides of the contraction opening 22. In addition to being fitted to the foot by the shoelaces 3, the upper 2 is also fitted to the foot by the adjusting component 5 provided on the upper 2. When the shoelaces 3 are loosened, the adjusting component 5 can further prevent the upper 2 from detaching from the foot, providing a good anti-loosening effect.
[0049] Reference Figure 2 The end of the fixing strap 51 away from its connection with the shoe upper 2 has a perforation 511, and the connecting ring 52 is inserted into the perforation 511. This connection method allows the connecting ring 52 to move relative to the fixing strap 51, making it flexible to operate.
[0050] Reference Figure 3 In this embodiment, the interlocking component 54 is preferably a hook and loop fastener male piece 541 and a hook and loop fastener female piece 542 that are bonded together. The hook and loop fastener male piece 541 is fixedly connected to the movable section 532, and the hook and loop fastener female piece 542 is fixedly connected to the fixed section 531. When the positioning band 53 is unfolded, the hook and loop fastener male piece 541 and the hook and loop fastener female piece 542 are located on the same side of the positioning band 53. The movable section 532 and the fixed section 531 are connected together by hook and loop fasteners, which has the effect of easy disassembly and easy putting on and taking off protective shoes. In addition, during use, the bonding position of the hook and loop fastener male piece 541 and the hook and loop fastener female piece 542 can be adjusted to change the connection length between the movable section 532 and the fixed section 531, thereby adjusting the tightness of the fit between the shoe upper 2 and the foot to accommodate different foot sizes.
[0051] The implementation principle of a protective shoe with anti-loosening function according to an embodiment of this application is as follows: When wearing the shoe, first, alternately thread the shoelaces 3 through the through holes 221 on both sides of the contraction opening 22 and tighten the shoelaces 3. Then, pass the positioning strap 53 through the connecting ring 52 and fold it to one side, so that the male Velcro piece 541 and the female Velcro piece 542 are bonded to each other, so that the fixing strap 51 is attached to the shoe upper 2, making the shoe upper 2 fit more tightly to the foot. When the shoelaces 3 are loosened, since the movable section 532 and the fixed section 531 are connected together, the fixing strap 51 can further prevent the shoe upper 2 from detaching from the foot, resulting in a good anti-loosening effect.
[0052] Example 2
[0053] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the end of the fixing strap 51 away from the connecting ring 52 is provided with a fixing hole 512, and a fixing button 24 that cooperates with the fixing hole 512 is sewn and fixed on the shoe upper 2, so that the fixing strap 51 can be detachably connected to the shoe upper 2. If the fixing strap 51 needs to be replaced, simply pass the fixing button 24 through the fixing hole 512. This connection method has the effect of making the style of the fixing strap 51 flexible and varied.
[0054] Reference Figure 5 and Figure 6 The connecting ring 52 includes a first half-ring 521 and a second half-ring 522 that are magnetically attracted to each other. The first half-ring 521 and the second half-ring 522 are made of magnetic material. The positioning band 53 passes through the connecting hole 525 formed by the first half-ring 521 and the second half-ring 522. When the connecting ring 52 is worn, it can be disassembled into the first half-ring 521 and the second half-ring 522, making it easy to replace the connecting ring 52 individually or to separate the connecting ring 52 from the fixing band 51 as needed. A stop block 523 is fixedly connected to the side of the first half-ring 521 near the second half-ring 522. The second half-ring 522 has a stop groove 524 that engages with the stop block 523, making the connection strength between the first half-ring 521 and the second half-ring 522 higher.
[0055] Reference Figure 6 The interlocking component 54 includes an interlocking male buckle 543 and an interlocking female buckle 544 that engage with each other. The interlocking male buckle 543 is fixedly connected to the movable section 532, and the interlocking female buckle 544 is fixedly connected to the fixed section 531. When the positioning belt 53 is unfolded, the interlocking male buckle 543 and the interlocking female buckle 544 are located on the same side of the positioning belt 53. The movable section 532 and the fixed section 531 are connected together by the interlocking of the interlocking male buckle 543 and the interlocking female buckle 544. This connection method has the advantages of high connection strength and convenient disassembly.
[0056] The implementation principle of this application embodiment is as follows: During assembly, the fixing strap 51 is first connected to the shoe upper 2 via the fixing button 24. Then, the first half-ring 521 and the second half-ring 522 are respectively inserted into the two sides of the through hole 511 and connected together. Next, the positioning strap 53 is inserted into the connecting ring 52 and flipped to one side, so that the interlocking male buckle 543 and the interlocking female buckle 544 are engaged with each other, thus making the fixing strap 51 fit against the shoe upper 2. If it is necessary to replace the fixing strap 51 or the connecting ring 52, simply unfasten the fixing button 24 and separate the connecting ring 52, which is convenient to operate.
[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
