Description

Technical Field

[0001] This utility model relates to the field of safety shoe technology, and in particular to a puncture-resistant safety shoe. Background Technology

[0002] Safety shoes are designed to protect the wearer's feet from various injuries. They are often used in construction sites or factories with a lot of heavy equipment to protect the wearer's feet. They usually have insulation, waterproof and slip-resistant properties. Some safety shoes also have metal plates inside the shoe to prevent impact and puncture.

[0003] While existing safety shoes can provide effective protection, they are prone to developing odors after prolonged wear due to poor breathability. Furthermore, safety shoes are heavy and require considerable effort to put on and take off.

[0004] Chinese patent CN221330374U discloses a puncture-resistant safety shoe, comprising: an upper; a puncture-resistant mechanism disposed at the bottom of the upper; and a heel disposed at one end of the puncture-resistant mechanism. The puncture-resistant mechanism includes: a shock-absorbing layer disposed at the bottom of the upper; a first puncture-resistant layer disposed on one side of the shock-absorbing layer; a second puncture-resistant layer disposed on one side of the first puncture-resistant layer; and a heel disposed on one side of the second puncture-resistant layer. In this puncture-resistant safety shoe, the original steel plate is replaced with an aluminum strip. At the same hardness, the aluminum strip is lighter and more flexible, thus reducing the weight of the safety shoe and facilitating walking. It also prevents punctures from sharp objects. Furthermore, the shock-absorbing memory foam in the shock-absorbing layer conforms to the curve of the user's foot, reducing vibration. Simultaneously, the antibacterial and deodorizing material inside the cavity can disinfect and deodorize the user's feet after long-term use, increasing the multifunctionality of the puncture-resistant safety shoe.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing safety shoes feature metal plates on both the upper and sole. While these plates provide good puncture protection, in scenarios such as construction, punctures to the upper are rare. Furthermore, the metal plates are difficult to remove flexibly depending on the usage scenario. Although they offer protection when punctured, deformation of the metal plate at the puncture site results in a sharper puncture point, leading to poor comfort and inconvenience for wearers.

[0006] Therefore, a puncture-resistant safety shoe is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a puncture-resistant safety shoe that solves the problem that existing safety shoes have metal plates on the upper and sole. Although these plates provide good puncture protection, in situations such as construction, where the upper is rarely punctured, the metal plates are difficult to remove flexibly depending on the usage scenario. Furthermore, while they can provide protection when punctured, the puncture point also deforms after the metal plate deforms, resulting in a sharp puncture point, poor comfort when worn, and inconvenience.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a puncture-resistant safety shoe, comprising a sole, a shoe body, and a toe guard, wherein the toe guard is movably connected to the top of the sole, the sole is sewn to the bottom of the shoe body, a smooth sleeve is fixedly connected to the inner side of the sole, and the inner side of the smooth sleeve is movably connected to the toe guard.

[0009] The sole includes a stepping part, the bottom of which has a sandwich part, the bottom of which has a rubber part, a protective plate on the inner side of the stepping part, a cavity on the inner side of the sandwich part, a support airbag fixedly connected to the inner side of the sandwich part, and a metal plate layer between the rubber part and the sandwich part.

[0010] Preferably, the toe protector includes a leather-fitting frame, and a thin metal sheet is inserted into the inner side of the leather-fitting frame.

[0011] Preferably, the front and rear sides of the bottom of the leather-fitting frame are sewn with straps, and the bottom of the front strap is fixedly connected to an insert plate, the outer side of which is inserted into a smooth sleeve.

[0012] Preferably, the bottom of the rear strap is fixedly connected to a buckle, and the bottom of the buckle is fixedly connected to the insert plate.

[0013] Preferably, the left side of the leather bonding frame is rotatably connected to the upper panel via a hinge, and the right side of the shoe body is provided with a magnetic buckle, and the right side of the shoe body is bonded to the upper panel via the magnetic buckle.

[0014] Preferably, the inner side of the front strap is movably connected to an adjusting buckle, and the front and rear sides of the inner side of the insert plate are provided with through holes for use with the strap.

[0015] Preferably, the protective plate is honeycomb-shaped and is made of polyvinyl chloride material.

[0016] Preferably, the metal plate layer is configured as a plurality of longitudinal arcs, and is separated by spaced transverse arcs, and the top of the metal plate layer is provided with a thickened strip.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application uses a sole and shoe body as the main body of the safety shoe. The foot-stepping part directly contacts the person's foot. The interlayer part, together with the support airbag, supports the foot-stepping and extends the distance between the ground and the person's foot. When the foot-stepping part is stepped on, the entire sole is pressed down, which squeezes the airflow out of the interlayer part. The rebound of the support airbag pushes the external airflow into the interlayer part. The metal plate layer provides good puncture protection against sharp objects stepped on, thus providing good protection.

[0019] 2. This application features a detachable toe guard, which can be flexibly installed on the shoe surface when protection of the shoe upper is needed, and provides puncture protection for the shoe upper. When not in use, the toe guard can be easily removed from inside the smooth cover for later use. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A puncture-resistant safety shoe includes a sole 1, a shoe body 2, and a toe guard 3. The toe guard 3 is movably connected to the top of the sole 1. The sole 1 is sewn to the bottom of the shoe body 2. A smooth sleeve 4 is fixedly connected to the inner side of the sole 1. The inner side of the smooth sleeve 4 is movably connected to the toe guard 3.

[0030] The sole 1 includes a stepping part 101, a sandwich part 102 at the bottom of the stepping part 101, a rubber part 103 at the bottom of the sandwich part 102, a protective plate 104 on the inner side of the stepping part 101, a cavity on the inner side of the sandwich part 102, a support airbag 105 fixedly connected to the inner side of the sandwich part 102, and a metal plate layer 106 between the rubber part 103 and the sandwich part 102.

[0031] In this embodiment: the sole 1 and the shoe body 2 are set as the main body of the safety shoe. The stepping part 101 directly contacts the person's foot. The interlayer part 102 is a hollow part. Together with the support airbag 105, it plays a good role in cushioning the stepping. When the stepping part 101 is stepped on, the entire sole 1 is pressed down, which will squeeze the airflow out of the interlayer part 102. The rebound of the support airbag 105 will push the external airflow into the interlayer part 102, which will have a ventilation effect on the stepping part 101. The metal plate layer 106 is used to play a good role in preventing punctures from sharp objects. Even if the metal plate layer 106 and the thicker interlayer part 102 are penetrated, they will come into contact with the protective plate 104 to block the puncture and play a good protective role.

[0032] Specifically, such as Figure 5 As shown, the toe protector 3 includes a leather fitting frame 301, and a metal sheet 302 is inserted into the inner side of the leather fitting frame 301.

[0033] Specifically, such as Figure 5 As shown, the front and back sides of the bottom of the leather-fitting frame 301 are sewn with straps 303. The bottom of the front strap 303 is fixedly connected to the insert plate 304, and the outer side of the insert plate 304 is inserted into the smooth sleeve 4.

[0034] Specifically, such as Figure 5 As shown, a buckle 305 is fixedly connected to the bottom of the rear strap 303, and the bottom of the buckle 305 is fixedly connected to the insert plate 304.

[0035] In this embodiment: by setting a detachable toe guard 3, when the shoe upper needs protection, the insert plate 304 can be inserted into the inside of the smooth sleeve 4, and the strap 303 and the insert plate 304 can be quickly connected by the buckle 305, thus protecting the shoe upper from puncture. When not needed, the toe guard 3 can be removed from the inside of the smooth sleeve 4 by unfastening the buckle 305. The leather fitting frame 301 can make the metal sheet 302 fit against the shoe upper when the strap 303 is tightened, and avoid the discomfort caused by the entire top of the toe guard 3 being a rigid structure, making it difficult for people to curl and wear.

[0036] Specifically, such as Figure 1 and Figure 6 As shown, the left side of the leather bonding frame 301 is connected to the upper plate 5 via a hinge, and the right side of the shoe body 2 is provided with a magnetic buckle, and the right side of the shoe body 2 is bonded to the upper plate 5 via the magnetic buckle.

[0037] Specifically, such as Figure 5 , Figure 6 As shown, the inner side of the front strap 303 is movably connected to an adjusting buckle 6, and the front and rear sides of the inner side of the insert plate 304 are provided with through holes that cooperate with the strap 303.

[0038] In this embodiment: by setting the adjustment buckle 6, the length of the strap 303 can be easily adjusted according to the size of the shoe. The through hole can facilitate the connection between the strap 303 and the insert plate 304. The shoe upper plate 5 can protect the front of the person's foot and is fixed by magnetic buckle. The shoe upper plate 5, which can rotate along the leather fitting frame 301, can facilitate a certain range of movement when the person walks, so as to avoid obstructing the person's movement.

[0039] Specifically, such as Figure 3 As shown, the protective plate 104 is designed in a honeycomb shape and is made of polyvinyl chloride material.

[0040] Specifically, such as Figure 4 As shown, the metal plate layer 106 is configured as several longitudinal arcs, and is separated by intermittent transverse arcs. The top of the metal plate layer 106 is provided with a thickened strip 7.

[0041] In this embodiment: by setting several longitudinal arc-shaped metal plate layers 106 separated by intermittent transverse arc-shaped sections, when a person steps on an item that may be punctured, it will slide along the arc surface to the bottom of the arc. Even if puncture occurs, it will be guided to the position of the thickened strip 7, and when it punctures the protective plate 104, it will cause the punctured item to tilt and penetrate, thus achieving a good protective effect. The elasticity of polyvinyl chloride material is limited, but its strength is high, so it can achieve a good blocking effect.

[0042] Working principle: When worn, the footrest 101 directly contacts the wearer's foot. The interlayer 102, as a hollow section, works with the support airbag 105 to support and cushion the foot during stepping. When the footrest 101 is stepped on, the entire sole 1 is compressed, forcing airflow out of the interlayer 102. The rebound of the support airbag 105 then pushes external airflow into the interlayer 102, providing ventilation for the footrest 101. The metal plate layer 106 is used to protect against sharp objects stepped on. The product provides good puncture protection. Even if it penetrates the metal plate layer 106 and the thicker interlayer 102, it will still come into contact with the protective plate 104 to block the puncturing object and provide good protection. If it is necessary to protect the instep of the person, the insert plate 304 is inserted into the inside of the smooth sleeve 4, and the strap 303 and the insert plate 304 are quickly connected by the buckle 305 to protect the shoe surface from puncture. The leather bonding frame 301 can make the metal sheet 302 adhere to the shoe surface when the strap 303 is tightened.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
