Description

Technical Field

[0001] This utility model relates to the field of safety shoe technology, specifically to a steel midsole structure for safety shoes. Background Technology

[0002] Steel midsoles are safety components used in work safety shoes. Work safety shoes are essential safety protective equipment for employees on production lines in heavy industries both domestically and internationally. The steel toe cap helps protect the toes from injury when heavy objects fall or hit the foot, while the steel midsole protects the sole from punctures by sharp objects. However, existing steel midsole structures have the following problems: 1) The connection to the sole is not tight enough, making the steel midsole prone to detachment; 2) The steel plate itself is quite hard, resulting in poor breathability and low comfort. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a steel midsole structure for safety shoes that can improve the strength and breathability of the steel midsole structure.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] A steel midsole structure for safety shoes includes a steel plate embedded inside the sole, with a protective side plate provided on the bottom periphery of the steel plate for lateral protection, the protective side plate forming a groove with the bottom surface of the steel plate; the top surface of the groove at the bottom of the steel plate is heat-fused to the sole; and the top of the steel plate is provided with a corrosion-resistant layer, a cushioning and shock-absorbing layer, and an anti-slip and wear-resistant layer from bottom to top.

[0006] The aforementioned steel midsole structure for safety shoes has a protective side plate with an outwardly bent bottom portion, and an embedded groove on the sole that matches the bent portion.

[0007] The aforementioned steel midsole structure for safety shoes comprises a three-layer composite structure, with a middle layer being a highly elastic and breathable rubber layer, and the upper and lower layers being high-strength steel sheets. The high-strength steel sheets are provided with strip-shaped ventilation holes made using an etching process.

[0008] The aforementioned steel midsole structure for safety shoes features an EVA foam material for the cushioning and shock-absorbing layer, which is provided with honeycomb-shaped breathable mesh.

[0009] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0010] This utility model provides a steel midsole structure for safety shoes. By setting a protective side plate at the bottom of the steel plate and embedding an outwardly bent part at the bottom of the protective side plate into the sole, the connection between the steel plate and the sole is ensured. Moreover, the steel plate itself adopts a three-layer composite structure. Through the cooperation of the rubber layer and the ventilation holes on the steel plate, the breathability of the steel plate is ensured without affecting the support strength and protection of the steel plate. Finally, a corrosion-resistant layer, a cushioning and shock-absorbing layer, and an anti-slip and wear-resistant layer are sequentially set on the top of the steel plate, which improves the comfort of the steel midsole structure.

[0012] Figure 2 This is a schematic diagram of the specific structure of the bottom of this utility model;

[0013] Figure 3 This is a schematic diagram of the components of this utility model.

[0014] The components include: 1. steel plate, 2. protective side plate, 3. bending section, 4. groove, 5. corrosion-resistant layer, 6. buffer and shock-absorbing layer, and 7. anti-slip and wear-resistant layer. Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] A steel midsole structure for safety shoes, such as Figures 1 to 3 As shown, the shoe includes a steel plate 1 embedded inside the sole, and a protective side plate 2 is provided on the bottom periphery of the steel plate 1 for side protection. The protective side plate 2 and the bottom surface of the steel plate 1 form a groove 4, and the top surface of the groove 4 at the bottom of the steel plate 1 is heat-fused to the sole.

[0017] The top of the steel plate 1 is provided with a corrosion-resistant layer 5, a buffer and shock-absorbing layer 6, and an anti-slip and wear-resistant layer 7 from bottom to top. By setting the corrosion-resistant layer 5, the corrosion resistance of the steel plate can be improved and the service life of the steel plate can be extended.

[0018] The cushioning and shock-absorbing layer 6 is made of EVA foam material and has honeycomb-shaped breathable mesh. By setting the cushioning and shock-absorbing layer 6, the impact force transmitted from the ground when walking can be effectively absorbed, ensuring both cushioning effect and a certain degree of support.

[0019] The anti-slip and wear-resistant layer 7 is made of polyurethane material, which can ensure a good anti-slip effect and also has a certain degree of flexibility, making it easy to walk on.

[0020] The bottom of the protective side panel 2 is a bent part 3 that bends outward, and the sole is provided with an embedded groove that matches the bent part 3.

[0021] Steel plate 1 has a three-layer composite structure. The middle layer is a highly elastic and breathable rubber layer, and the top and bottom layers are high-strength steel sheets. The high-strength steel sheets are provided with strip-shaped breathable holes made by etching process.

[0022] This composite structure ensures the overall strength and puncture resistance of the steel plate. At the same time, due to the elastic deformation of the middle rubber layer, when pressure is applied to the foot, the rubber layer is compressed, and air is discharged from the vents; when the pressure is released, the rubber layer rebounds, and outside air is drawn in, thereby actively promoting air circulation and enhancing breathability.

[0023] This utility model provides a steel midsole structure for safety shoes. By setting a protective side plate at the bottom of the steel plate and embedding an outwardly bent part at the bottom of the protective side plate into the sole, the connection between the steel plate and the sole is ensured. Moreover, the steel plate itself adopts a three-layer composite structure. Through the cooperation of the rubber layer and the ventilation holes on the steel plate, the breathability of the steel plate is ensured without affecting the support strength and protection of the steel plate. Finally, a corrosion-resistant layer, a cushioning and shock-absorbing layer, and an anti-slip and wear-resistant layer are sequentially set on the top of the steel plate, which improves the comfort of the steel midsole structure.
