Description

Technical Field

[0001] This utility model relates to the field of workwear technology, specifically to a workwear that is heat-resistant and slag-resistant. Background Technology

[0002] Safety shoes are shoes that provide safety protection for the feet. There are many types of safety shoes, such as puncture-proof, insulating, oil-proof, impact-proof, and acid and alkali-proof. The selection of safety shoes should be based on the nature and degree of hazard in the work environment. In complex and harsh environments such as construction sites or workshops, workers' feet are easily injured by falling objects, punctures, or cuts. Wearing safety shoes can provide good protection for workers' feet.

[0003] In existing technologies, the tongue of safety shoes is movable at the position corresponding to the upper, with gaps. When the user is working, hot iron slag can easily fall into the shoe through the gap between the upper and the tongue, causing skin burns and reducing the user's safety. Alternatively, it can accumulate inside the shoe, interfering with the user's work. At the same time, existing safety shoes have weak grip. When workers walk or move on oily or muddy ground, the friction between the sole and the ground is insufficient, leading to slips and increasing the user's work risk. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a work shoe that is heat-proof and slag-proof, so as to solve the problems mentioned in the background art that high-temperature iron slag can easily fall into the shoe through the gap between the upper and the tongue during operation and that the work shoe has a weak grip.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A type of work shoe that is heat-resistant and slag-resistant includes an upper, a metal toe cap fixedly connected to the front of the upper, an edge band fixedly connected to the bottom of the upper, a connecting guard plate fixedly connected to the inside of the upper by stitching, a tongue fixedly connected to the inside of the connecting guard plate by stitching, a rubber cushioning pad fixedly connected to the bottom of the edge band, a steel plate fixedly connected to the bottom of the rubber cushioning pad, a sole fixedly connected to the bottom of the steel plate, a sponge insole disposed inside the upper, a metal shell fixedly connected to the rear of the steel plate, a knob rotatably connected to the rear end of the metal shell, a connecting rod fixedly connected to one side of the knob, a worm gear fixedly connected to the outside of the connecting rod, a worm wheel meshing with the worm gear, a transmission screw fixedly connected to the bottom of the worm wheel, a sliding block threadedly connected to the transmission screw, a connecting plate fixedly connected to the bottom of the sliding block, a connecting block fixedly connected to the bottom of the connecting plate, an anti-slip spike fixedly connected to the bottom of the connecting block, and a cushioning component disposed inside the rubber cushioning pad.

[0007] In one alternative embodiment, the sole is provided with a pattern that can increase friction, and the upper 1, connecting plate 21 and tongue 2 are all made of soft cowhide.

[0008] In one alternative embodiment, a through hole is provided on the sole, and the connecting block is slidably connected to the inside of the sole through the through hole.

[0009] In one optional embodiment, a second through hole is provided on the metal casing, and the connecting rod is rotatably connected to the inside of the metal casing through the second through hole.

[0010] In one optional embodiment, a through hole three is provided on the metal casing, and the worm gear is rotatably connected to the inside of the metal casing through the through hole three.

[0011] In one optional embodiment, the buffer assembly includes a connecting cylinder fixedly connected to the inner side of the rubber buffer pad, a spring fixedly connected to the inner side of the connecting cylinder, and a sliding column fixedly connected to one side of the spring.

[0012] In one optional embodiment, the connecting cylinder has a through hole four, and the sliding column is slidably connected to the inside of the connecting cylinder through the through hole four.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By sewing the upper and tongue together with a connecting plate, the gap between them is eliminated, preventing hot iron slag from easily falling into the shoe during work. This improves user safety and allows the user to focus on work. The connecting plate, made of soft cowhide, offers good breathability. By connecting the two sides of the upper and tongue together, the plate effectively encloses and shields the sides of the tongue, providing reliable protection for the wearer's instep and preventing debris from entering the shoe.

[0015] 2. When the user wants to increase the grip of this device, turning the knob will rotate the connecting rod, which in turn rotates the worm gear, which in turn rotates the worm wheel, which in turn rotates the transmission screw, which in turn lowers the sliding block, which in turn lowers the connecting block, which in turn lowers the anti-slip spikes. This allows the anti-slip spikes to be exposed through the holes in the sole of the shoe, making it easier for the anti-slip spikes to embed into soft ground or penetrate oily surfaces when the user walks, forming physical grip points. This increases the device's grip and friction with the ground, reducing the risk of the user slipping and thus reducing operational risks.

[0016] 3. When the foot lands or is subjected to external pressure, the rubber cushioning pad first contacts the ground and deforms, initially absorbing some of the impact and vibration, reducing the direct transmission of force to the foot. Subsequently, the remaining impact force will push the sliding column downward, compressing the spring at the bottom. The spring converts the impact force into elastic potential energy through elastic deformation, further dissipating the force and preventing the impact force from acting directly on the ball of the foot or heel, thereby increasing the user's wearing comfort.

[0028] Please see Figures 1-6This utility model provides an embodiment of a heat-resistant and slag-resistant work shoe, comprising a shoe upper 1, a metal toe cap 3 fixedly connected to the front of the shoe upper 1, an edge banding 4 fixedly connected to the bottom of the shoe upper 1, a connecting guard 21 fixedly connected to the inner side of the shoe upper 1 by stitching, a shoe tongue 2 fixedly connected to the inner side of the connecting guard 21 by stitching, a rubber cushioning pad 5 fixedly connected to the bottom of the edge banding 4, a steel plate 6 fixedly connected to the bottom of the rubber cushioning pad 5, a sole 7 fixedly connected to the bottom of the steel plate 6, a sponge insole 811 disposed inside the shoe upper 1, a metal outer shell 801 fixedly connected to the rear of the steel plate 6, a knob 802 rotatably connected to the rear end of the metal outer shell 801, and a connecting rod fixedly connected to one side of the knob 802. 803, a worm gear 804 fixedly connected to the outside of the connecting rod 803, a worm wheel 805 meshing with the worm gear 804 on one side, a transmission screw 806 fixedly connected to the bottom of the worm wheel 805, a sliding block 807 threadedly connected to the transmission screw 806, a connecting plate 809 fixedly connected to the bottom of the sliding block 807, a connecting block 810 fixedly connected to the bottom of the connecting plate 809, an anti-slip spike 808 fixedly connected to the bottom of the connecting block 810, and a buffer assembly set inside the rubber buffer pad 5. The shoe upper 1 and the shoe tongue 2 are sewn together by a connecting guard 21, which consists of two symmetrical pieces. One edge of the connecting guard 21 is sewn to the inner wall of the shoe upper 1 below the shoelace hole on the corresponding side. Next, the other edge of the connecting plate 21 is sewn to the nearest side edge of the shoe tongue 2, thus eliminating the gap between the upper 1 and the shoe tongue 2. This prevents hot iron slag from easily falling into the shoe through the gap between the upper 1 and the shoe tongue 2 during operation, thereby improving the user's safety and allowing the user to concentrate on work. At the same time, the connecting plate 21, which connects the upper 1 and the shoe tongue 2, is made of soft cowhide and has good breathability. By connecting the left and right side edges of the upper 1 and the shoe tongue 2 together through the connecting plate 21, the side edge of the shoe tongue 2 can effectively play a role in enclosure, sealing and shielding protection. It not only provides reliable protection for the wearer's instep, but also effectively prevents debris from entering the shoe. When the user wants to increase the grip of this device... When the knob 802 is turned, the connecting rod 803 rotates, which in turn drives the worm gear 804 to rotate. The worm gear 804 drives the worm wheel 805 to rotate, which in turn drives the transmission screw 806 to rotate. The transmission screw 806 drives the sliding block 807 to descend, which in turn drives the connecting block 810 to descend. The connecting block 810 drives the anti-slip spike 808 to descend, thus exposing the anti-slip spike 808 through the through hole in the sole 7. This allows the anti-slip spike 808 to embed into soft ground or penetrate oily surfaces when the user walks, forming physical grip points. This increases the device's grip and friction with the ground, reducing the risk of the user slipping and thus minimizing operational risks.

[0029] In a preferred embodiment of this utility model, the sole 7 is provided with a pattern that increases friction. The upper 1, connecting plate 21, and tongue 2 are all made of soft cowhide, which helps to increase the friction between the device and the ground, thereby reducing the risk of slipping. The soft cowhide is soft and elastic, and can follow the bending and stretching of the foot without restricting walking and working movements. The fit of the tongue 2 and connecting plate 21 is also better. At the same time, the soft cowhide itself has a certain thickness and wear resistance, which can help resist minor burns and flying debris. Meanwhile, the natural fiber structure is breathable, reducing the stuffiness during long-term wear.

[0030] In a preferred embodiment of this utility model, a through hole is provided on the sole 7, and the connecting block 810 is slidably connected to the inside of the sole 7 through the through hole. This is beneficial when strong grip is required for ground operations, the connecting block 810 can be driven by the knob 802 to drive the anti-slip spike 808 to extend out of the sole 7 through the through hole, which greatly enhances the anti-slip performance of the sole 7 and prevents people from slipping. When walking on ordinary ground, the anti-slip spike 808 can be retracted into the sole 7 to maintain the normal walking experience of the sole 7 and at the same time avoid unnecessary wear and tear on the sole 7.

[0031] In a preferred embodiment of this utility model, a through hole 2 is provided on the metal shell 801, and the connecting rod 803 is rotatably connected to the inside of the metal shell 801 through the through hole 2. This allows the user to rotate the connecting rod 803 by rotating the knob 802, which in turn allows the connecting rod 803 to drive the worm gear 804 to rotate.

[0032] In a preferred embodiment of this utility model, a through hole 3 is provided on the metal shell 801, and the worm gear 805 is rotatably connected to the inside of the metal shell 801 through the through hole 3, which is beneficial for the worm 804 to drive the worm gear 805 to rotate, and thus beneficial for the worm gear 805 to drive the transmission screw 806 to rotate.

[0033] Please see Figure 6 In this embodiment, the cushioning assembly includes a connecting cylinder 902 fixedly connected to the inner side of the rubber cushioning pad 5, a spring 903 fixedly connected to the inner side of the connecting cylinder 902, and a sliding column 901 fixedly connected to one side of the spring 903. When the foot lands or is subjected to external pressure, the rubber cushioning pad 5 first contacts the ground and deforms, initially absorbing part of the impact force and vibration, reducing the direct transmission of force to the foot. Subsequently, the remaining impact force will push the sliding column 901 to move downward, compressing the spring 903 at the bottom. The spring 903 converts the impact force into elastic potential energy through elastic deformation, further dissipating the force and preventing the impact force from acting directly on the ball of the foot or heel, thereby increasing the user's wearing comfort.

[0034] In a preferred embodiment of this utility model, a through hole four is provided on the connecting cylinder 902, and the sliding column 901 is slidably connected to the inside of the connecting cylinder 902 through the through hole four. This helps the connecting cylinder 902 to restrict the sliding direction of the sliding column 901, ensuring that the spring 903 deforms only in the vertical direction, thus ensuring the stability of the buffering process. When the pressure disappears, the spring 903 resets, driving the sliding column 901 back to the initial position, preparing for the next buffering.

[0035] During operation, the upper 1 and tongue 2 are sewn together using a connecting piece 21. This connecting piece 21 consists of two symmetrical pieces. One edge of the connecting piece 21 is sewn to the inner wall of the upper 1 below the corresponding shoelace eyelet, and the other edge of the connecting piece 21 is sewn to the nearest side edge of the tongue 2. This eliminates the gap between the upper 1 and tongue 2, preventing hot iron slag from easily falling into the shoe through this gap during operation. This improves user safety and facilitates the use of... The user can focus on their work. Meanwhile, the connecting plate 21, which connects the upper 1 and the tongue 2, is made of soft cowhide and has good breathability. The connecting plate 21 connects the left and right sides of the upper 1 and the tongue 2, effectively protecting and shielding the side edges of the tongue 2. This not only provides reliable protection for the wearer's instep but also effectively prevents debris from entering the shoe. When the user wants to increase the device's grip, they can rotate the knob 802 to rotate the connecting rod 803, which in turn rotates the worm gear 804. The worm gear 804 drives the worm wheel 805 to rotate, which in turn drives the transmission screw 806 to rotate. The transmission screw 806 then drives the sliding block 807 to descend, which in turn drives the connecting block 810 to descend. The connecting block 810 then drives the anti-slip spike 808 to descend, thus exposing the anti-slip spike 808 through the through-hole in the sole 7. This allows the anti-slip spike 808 to embed itself into soft ground or penetrate oily surfaces when the user walks, forming physical grip points. This increases the device's grip and friction with the ground, thereby reducing... The system reduces the risk of slipping, thus minimizing operational risks for users. When the foot lands or is subjected to external pressure, the rubber cushioning pad 5 first contacts the ground and deforms, initially absorbing some of the impact and vibration, reducing the direct transmission of force to the foot. Subsequently, the remaining impact force pushes the sliding column 901 downward, compressing the spring 903 at the bottom. The spring 903 converts the impact force into elastic potential energy through elastic deformation, further dissipating the force and preventing the impact force from acting directly on the ball of the foot or heel, thereby increasing the user's wearing comfort.

[0037] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
