Description

Technical Field

[0001] The present invention belongs to the technical field related to rescue shoes, and in particular relates to a fire rescue shoe with a protection function. Background Art

[0002] The main duties of firefighters include extinguishing fires, rescuing disasters, inspecting fire safety facilities and promoting fire safety knowledge. At the same time, they also participate in rescue work, such as road rescue, ambulance rescue, serving the people, inspecting safe water sources of water supply companies, and internal duties. When firefighters perform tasks, they often wear fire rescue shoes, which can adapt to high temperatures and complex road conditions to provide corresponding protection for the personal safety of firefighters.

[0003] After retrieval, the Chinese patent with the patent publication number CN220369570 discloses a rescue shoe, which has a Kevlar insole in the sole to play a puncture-proof role. According to the road conditions, it is possible to choose to use spikes or frustum-shaped bumps. On normal roads, the frustum-shaped bumps can be screwed onto the single-headed bolts, and when facing an inclined slope, the spikes can be replaced to increase the grip.

[0021] A zipper part 9 is arranged on the side surface of the shoe body main body 1.

[0022] A placement groove 10 is arranged on the sole main body 3, a plurality of buckles 11 are arranged in the placement groove 10, and the plurality of buckles 11 are used for clamping and limiting the micro gas storage tank 7, and a barrier door 12 is arranged on the sole main body 3.

[0023] The expansion layer 44 has a two-layer structure, its inner layer is a composite rubber layer 13, and its outer layer is a fiber reinforcement layer 14.

[0024] When the above device is actually in use, when firefighters wear this fire rescue shoe to perform rescue tasks, if a heavy object falls and is about to hit the firefighters' feet, the sensor 5 will detect the danger, send a signal through the control module, open the solenoid valve 8, and the micro gas storage tank 7 will output compressed gas into the expansion layer 44, driving the expansion layer 44 to expand. After the expansion layer 44 expands, it can buffer when a heavy object falls, reducing the injury to the firefighters' feet.

[0025] The expansion layer 44 is connected to the connection box body 43 through a storage unit. The lower end of the connection box body 43 is fixedly connected with a first insertion rod 15 inserted into the insertion hole 6. A protruding air inlet 16 is arranged on the side surface of the first insertion rod 15. A first air passage 17 matched with the protruding air inlet 16 is opened in the insertion hole 6. A blocking unit is arranged on the first air passage 17. A pressure relief valve 18 for releasing the gas in the expansion layer 44 is arranged on the connection box body 43.

The first connecting plates 24 are connected to the inner wall of the second clamping groove 25 through a first spring 27 for providing elastic force. The first spring 27 is sleeved on the outer side of the first guiding rod 26.

[0028] When firefighters wear this fire rescue shoe, if the task they are performing is not dangerous, they may not insert the first inserting rod 15 into the inserting hole 6. At this time, under the blocking effect of the blocking plate 22, the first air duct 17 will not release compressed gas to the outside, and the sensor 5 is closed, so that the micro gas storage tank 7 will not output compressed gas. Or, the firefighters can choose to insert the first inserting rod 15 into the inserting hole 6 at a suitable position according to the position of the foot they want to protect. When inserting the first inserting rod 15, driven by the protruding air inlet 16, the moving protrusion 23 provided on the blocking plate 22 moves downward, driving the blocking plate 22 to move downward. The first connecting plate 24 moves downward in the direction of the first guiding rod 26 until the protruding air inlet 16 is stuck in the first air duct 17, and the first air duct 17, the second air duct 19, the third air duct 20 and the fourth air duct 45 are communicated, and compressed air can be input into the expansion layer 44 to protect the feet of the firefighters.

[0029] Combined with Figure 7 , Figure 8 , Figure 9 and Figure 10 , after the firefighters press the pressure relief valve 18, the compressed gas in the expansion layer 44 will be discharged. In order to store the expansion layer 44, a storage unit is provided. The storage unit includes a moving groove 28 opened on the connecting box body 43. A moving push rod 29 is inserted into the moving groove 28. The upper end of the moving push rod 29 is fixedly connected with a second connecting plate 30. The second connecting plate 30 is connected with a third connecting plate 31 through a limiting unit. The third connecting plate 31 is connected with the expansion layer 44.

[0030] The limiting unit includes a plurality of second guiding rods 32 fixedly connected to the inner wall of the connecting box body 43. A fourth connecting plate 33 is sleeved on the outer sides of the plurality of second guiding rods 32. Limiting plates 34 are fixedly connected to the ends of the plurality of second guiding rods 32. The fourth connecting plate 33 is connected with the inner wall of the connecting box body 43 through a second spring 35 for providing elastic force. The second spring 35 is sleeved on the outer side of the second guiding rod 32. A limiting inserting rod 36 is fixedly connected to the side surface of the fourth connecting plate 33. A curved surface 37 is provided on the limiting inserting rod 36. A slot 38 matching with the limiting inserting rod 36 is opened on the second connecting plate 30. A second inserting rod 39 is fixedly connected to the side surface of the third connecting plate 31. The second inserting rod 39 is inserted into the slot 38. Symmetrically arranged guiding protrusions 40 are fixedly connected to the side surface of the second inserting rod 39. A guiding groove 41 matching with the guiding protrusions 40 is opened on the slot 38.

[0031] A limiting rod 42 for limiting the expansion layer 44 is fixedly connected to the connecting box body 43.

[0032] When the above storage unit is actually in use, the firefighter pushes the moving push rod 29 downward, driving the expansion layer 44 to move in the direction of the moving groove 28. After the second connecting plate 30 moves to the position of the limiting insertion rod 36, the limiting insertion rod 36 is inserted into the insertion slot 38 under the elastic force of the second spring 35 to limit the position of the second connecting plate 30, and the expansion layer 44 is also collected and waits for the next expansion.

[0033] When the expansion layer 44 expands, it drives the third connecting plate 31 to move towards the second connecting plate 30, driving the second insertion rod 39 to push the limiting insertion rod 36 in the insertion slot 38. As the expansion layer 44 continues to move, the second connecting plate 30 moves in the moving groove 28 until it moves to the uppermost end of the moving groove 28, ensuring that the expansion layer 44 is in an expanded state.

[0034] In summary, the working principle of the present invention is as follows: When a firefighter wears this fire rescue shoe to perform a rescue task, if a heavy object falls and is about to hit the firefighter's foot, the sensor 5 will detect the danger, send a signal through the control module, open the solenoid valve 8, and the micro gas storage tank 7 will output compressed gas into the expansion layer 44, driving the expansion layer 44 to expand. After the expansion layer 44 expands, it can buffer when a heavy object falls, reducing the injury to the firefighter's foot; When a firefighter wears this fire rescue shoe, if the task being performed is not dangerous, the first insertion rod 15 can not be inserted into the jack 6. At this time, under the blocking effect of the blocking plate 22, the first air duct 17 will not release compressed gas to the outside, and the sensor 5 is closed, so the micro gas storage tank 7 will not be triggered to output compressed gas. Or, the firefighter can choose to insert the first insertion rod 15 into the jack 6 at a suitable position according to the position of the foot to be protected. When inserting the first insertion rod 15, driven by the protruding air inlet 16, the moving protrusion 23 provided on the blocking plate 22 moves downward, driving the blocking plate 22 to move downward, and the first connecting plate 24 moves downward in the direction of the first guide rod 26 until the protruding air inlet 16 is stuck in the first air duct 17, and the first air duct 17, the second air duct 19, the third air duct 20, and the fourth air duct 45 are connected, enabling compressed air to be input into the expansion layer 44 to protect the firefighter's foot; The firefighter pushes the moving push rod 29 downward, driving the expansion layer 44 to move in the direction of the moving groove 28. After the second connecting plate 30 moves to the position of the limiting insertion rod 36, the limiting insertion rod 36 is inserted into the insertion slot 38 under the elastic force of the second spring 35 to limit the position of the second connecting plate 30, and the expansion layer 44 is also collected and waits for the next expansion.

[0035] When the expansion layer 44 expands, it drives the third connecting plate 31 to move towards the second connecting plate 30, driving the second insertion rod 39 to push the limit insertion rod 36 in the insertion slot 38. As the expansion layer 44 continues to move, the second connecting plate 30 moves in the movement groove 28 until it moves to the uppermost end of the movement groove 28, ensuring that the expansion layer 44 is in an expanded state.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
