Description

Technical Field

[0001] The invention relates to the technical field of fire-fighting equipment, in particular to a water rescue shoe with a detachable sole. Background Art

[0002] The environment for water rescue (such as after floods, waterlogging, and mudslides) is often extremely complex and changeable, requiring rescuers to frequently shuttle between mud, stagnant water, and hard surfaces (such as gravel and debris from collapsed buildings). Such scenarios are usually accompanied by extreme weather conditions (such as heavy rain and strong winds) and complex terrain features (such as deep water areas, gravel roads, and landslide areas), which pose severe challenges to the rescuers' mobility and equipment performance. In such an environment, rescuers not only need to face slippery, soft, or irregular surfaces, but also have to deal with dynamic factors such as changes in water depth and flow rate, which makes them have extremely high requirements for the performance of shoes; in order to quickly switch the sole mode, and have simple and reliable operation of water rescue shoes, so as to improve the rescuers' mobility, safety, and rescue efficiency, there is a need for a water rescue shoe with a detachable sole.

[0003] While existing water rescue shoes offer some waterproofing, they are difficult to effectively drain when water inevitably enters (e.g., when water depth exceeds the upper or when the shoe is soaked for extended periods). This accumulated water makes the shoe heavy and burdensome, significantly reducing the efficiency of rescuers. Prolonged use of wet shoes can easily lead to foot discomfort, slipping, and even foot diseases, posing a threat to safety and rescue efficiency. Furthermore, traditional water rescue shoes often feature pre-installed studs or anti-slip bumps on the soles to improve grip on slippery surfaces. However, these designs are particularly limited in performance and adaptability when extreme grip is required (e.g., steep slopes, slippery rocks), or when rapid traversal of smooth surfaces is required (e.g., inside rescue vehicles, on hard debris surfaces). Attaching external anti-slip devices (e.g., crampons) is cumbersome and time-consuming, making them unacceptable in time-sensitive rescue situations. Carrying multiple pairs of shoes designed for different terrains significantly increases the burden and is impractical. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a water rescue shoe with a detachable sole, which solves the problems of poor drainage performance, poor terrain adaptability, insufficient structural stability and inconvenient operation of existing rescue shoes in complex water environments.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A water rescue shoe with a detachable sole comprises a rescue shoe body, the outer wall of the rescue shoe body is provided with a one-way valve, the lower surface of the rescue shoe body is provided with a detachable sole, the outer wall of the detachable sole is fixedly connected to an L-shaped block, the interior of the detachable sole is provided with a first slot and a second slot, the interior of the rescue shoe body is fixedly connected to a support frame, the interior of the support frame is provided with a limiting component, the interior of the support frame is fixedly connected to a first triangular block, the interior of the support frame is slidably connected to a second triangular block, the outer wall of the second triangular block is slidably connected to a connecting block, the outer wall of the connecting block is provided with a limiting groove, the lower surface of the second triangular block is slidably connected to a connecting plate, the lower surface of the connecting plate is fixedly connected to an anti-slip spike, the interior of the support frame is provided with a first spring, and the interior of the rescue shoe body is provided with a connecting mechanism.

[0007] By adopting the above technical solutions: the one-way drainage valve and retractable anti-slip spike structure significantly improve the performance of rescue shoes at the junction of land and water and in complex terrain. The one-way valve cleverly uses the pressure and gravity of the shoe body during walking to actively discharge the accumulated water that has seeped into the shoe, effectively solving the weight increase and walking slip problems caused by water accumulation in the shoe body, and ensuring the safety of rescue personnel. The anti-slip spike mechanism adopts an exquisite combination of triangular block mechanical transmission and spring reset. The second triangular block is squeezed by the first triangular block and linked to the movement of the connecting plate. The spike body can be triggered or retracted with one click by sliding the connecting block. This design enables a single rescue shoe to instantly switch between wading mode and strong anti-slip mode, greatly enhancing the gripping ability on muddy, slippery and other dangerous ground, and significantly reducing the risk of rescue operations.

[0011] Preferably, one end of the first telescopic spring is fixedly connected to the outer wall of the first slide rail, and the other end is fixedly connected to the outer wall of the first sliding block. A second telescopic rod is provided between the first handle and the first limit frame. The outer wall of the second telescopic rod is slidably connected to the second telescopic spring. One end of the second telescopic spring is fixedly connected to the outer wall of the first handle, and the other end is fixedly connected to the inner wall of the first limit frame.

[0012] Preferably, the connecting mechanism includes a second limit frame, a second handle is slidably connected to the interior of the second limit frame, a second slide rail is fixedly connected to the interior of the second limit frame, and the interior of the second handle is slidably connected to the outer wall of the second slide rail.

[0013] Preferably, the outer wall of the second handle is rotatably connected to the second connecting rod, the outer wall of the second connecting rod is rotatably connected to the second slider, the lower surface of the second slider is fixedly connected to the second limit block, and the outer walls of the second slider and the second limit block are both slidably connected to the inside of the second slide rail.

[0014] Preferably, a third telescopic rod is provided between the two second sliders, and the outer wall of the third telescopic rod is slidably connected to a tension spring, the two ends of the tension spring are respectively fixedly connected to the outer walls of the two second sliders, and the outer wall of the second limit block is slidably connected to the inner wall of the first slot.

[0015] Preferably, the outer wall of the L-shaped block is slidably connected to the inside of the rescue shoe body, the outer wall of the second triangular block is slidably connected to the outer wall of the first triangular block, the outer wall of the connecting block is slidably connected to the outer wall of the rescue shoe body, the outer wall of the connecting plate is slidably connected to the inner wall of the support frame, the outer wall of the anti-slip spike is slidably connected to the inside of the rescue shoe body and the support frame, one end of the first spring is fixed to the lower surface of the connecting plate, and the other end abuts the inner wall of the support frame.

[0016] Preferably, the limiting assembly includes a support frame, the interior of the support frame is fixedly connected to a limiting cylinder, the inner wall of the limiting cylinder is slidably connected to a clamping block, the outer wall of the clamping block is slidably connected to the outer wall of the connecting block, the outer wall of the clamping block is slidably connected to the inner wall of the limiting groove, and the inner wall of the limiting cylinder is provided with a second spring, one end of the second spring is fixed to the clamping block, and the other end abuts against the inner wall of the limiting cylinder.

[0017] Working principle: When the rescue shoe is used, when anti-slip spikes are needed to increase friction, the sliding connecting block can be used to drive the second triangular block to slide in the support frame. Under the obstruction of the first triangular block, the second triangular block can slide downward on the connecting block, and then the second triangular block will squeeze the connecting plate to make it slide in the support frame. The connecting plate will squeeze the first spring to make it contract, and drive the anti-slip spikes to slide in the connecting plate, and then extend out of the detachable sole. At this time, the connecting block squeezes the clamping block while sliding, making it slide in the limiting cylinder and squeeze the second spring to contract. Under the rebound of the second spring, the clamping block can be stuck in the limiting groove in the connecting block, thereby limiting the position of the connecting block;

[0018] When water enters the rescue shoe body, the accumulated water will be discharged through the one-way valve under the action of gravity during walking, thereby effectively preventing the accumulation of water in the rescue shoe body and affecting walking;

[0019] By pressing the first handles on both sides at the same time, the second telescopic rod and the second telescopic spring can be squeezed under the limit of the first slide rail, and the first handle drives the first sliding block to slide on the first slide rail through the first connecting rod, thereby squeezing the first telescopic rod and the first telescopic spring to contract, and the first sliding block drives the first limiting block to slide in the second slot, thereby allowing the detachable sole to be removed. When installing the detachable sole, first insert the L-shaped block into the groove at the bottom of the rescue shoe body, then insert the first limiting block into the second slot, release the first handle, and under the rebound of the first telescopic rod and the second telescopic rod, the first limiting block can be inserted into the second slot, thereby allowing the detachable sole to be installed;

[0020] By pulling the second handle at the same time to make it slide on the second slide rail, the second handle can pull the second slider to slide on the second slide rail through the second connecting rod, thereby stretching the third telescopic rod and the tension spring to stretch it, and driving the second limiting block to slide in the first slot through the second slider. When the second limiting block slides out of the first slot, the detachable sole can be disassembled. When installing the detachable sole, the L-shaped block is similarly clamped into the rescue shoe body, and then the second limiting block is inserted into the first slot, and then the second handle is released. Under the retraction action of the tension spring, the second limiting block can be clamped in the first slot, thereby completing the installation of the detachable sole.

[0021] The present invention provides a water rescue shoe with a detachable sole. It has the following beneficial effects:

[0022] 1. This invention achieves efficient adaptation to both water and land environments through a one-way valve and anti-slip stud mechanism. The one-way valve design automatically drains water from the shoe during walking, preventing water retention that could cause the shoe to become heavy or slippery, thereby improving the safety of rescue personnel. The anti-slip stud utilizes a triangular block linkage structure and a spring-driven design. The stud can be extended and retracted from the sole by sliding a connecting block. During operation, the second triangular block is squeezed by the first triangular block, driving the connecting plate downward. This synergistic effect of the first spring ensures stable extension and retraction of the stud. This function allows the shoe to quickly switch between anti-slip mode in water and regular walking mode, significantly enhancing grip on complex terrain and reducing the risks of rescue operations.

[0023] 2. The present invention presses the first handles on both sides at the same time. Under the limit of the first slide rail, the first handle drives the first sliding block to slide on the first slide rail through the first connecting rod, and then drives the first limiting block to slide in the second slot, so that the detachable sole can be disassembled. When installing the detachable sole, first insert the L-shaped block into the groove at the bottom of the rescue shoe body, then insert the first limiting block into the second slot, release the first handle, and under the rebound of the first telescopic spring and the second telescopic spring, the first limiting block can be inserted into the second slot, and then the detachable sole can be installed.

[0024] 3. The present invention simultaneously pulls the second handle to make it slide on the second slide rail, thereby stretching the third telescopic rod and the tension spring to stretch them, and drives the second limiting block to slide in the first slot through the second slider. When the second limiting block slides out of the first slot, the detachable sole can be disassembled. When installing the detachable sole, the L-shaped block is similarly inserted into the rescue shoe body, and then the second limiting block is inserted into the first slot. Then, the second handle is released, and under the retraction action of the tension spring, the second limiting block can be stuck in the first slot, thereby completing the installation of the detachable sole.

[0025] During the stud extension and retraction process, the locking block within the retaining cylinder automatically engages the retaining groove of the connecting block via a second spring. This, combined with four sets of retaining units on either side of the support frame, creates a double lock: two retaining units engage the retaining grooves, and two abut the outer wall, completely preventing accidental retraction of the studs due to accidental contact. The first and second rail systems within the connecting mechanism, through rigid guides and elastic elements, ensure smooth handle operation while preventing mechanism failure due to spring compression and deflection. All moving parts are equipped with telescopic rod retaining structures to constrain spring deformation within the axial range, ensuring the reliability of the rescue equipment in extreme environments.

Under the obstruction of the first triangular block 7, the second triangular block 8 can slide downward on the connecting block 9. Then the second triangular block 8 will squeeze the connecting plate 11 to make it slide in the support frame 6. The connecting plate 11 will squeeze the first spring 13 to make it contract, and drive the anti-slip spike 12 to slide in the connecting plate 11, thereby extending out of the detachable sole 2. At this time, the blocking block 15 will limit the position of the connecting block 9. When the anti-slip spike 12 is retracted, it is only necessary to slide the connecting block 9 back. Under the rebound action of the first spring 13, the anti-slip spike 12 can be retracted.

The first telescopic rod 23 and the first telescopic spring 24 are respectively pressed together and compressed, thereby the first telescopic rod 23 and the first telescopic spring 24 are compressed. The first telescopic rod 23 plays a role of limiting the first telescopic spring 24, which can prevent the first telescopic spring 24 from deflecting when compressed, thereby increasing the stability of the first telescopic spring 24 and extending the service life of the first telescopic spring 24. The first sliding block 21 drives the first limiting block 22 to slide in the second slot 5, wherein the second slot 5 can just engage with the first limiting block 22, thereby allowing the detachable sole 2 to be disassembled. When installing the detachable sole 2, first, the L-shaped block 3 is inserted into the groove at the bottom of the rescue shoe body 1, wherein the groove in the rescue shoe body 1 can limit the L-shaped block 3.

One end of the first spring 13 is fixed to the lower surface of the connecting plate 11, and the other end abuts the inner wall of the support frame 6.

[0043] Specifically, by simultaneously pulling the second handle 28, it can slide on the second slide rail 29, wherein the second slide rail 29 limits the second handle 28, thereby ensuring the stability of the second handle 28 during the sliding process, and the second handle 28 pulls the second slider 31 to slide on the second slide rail 29 through the second connecting rod 30, wherein the second connecting rod 30 connects the second handle 28 and the second slider 31, thereby ensuring the synchronization of the movement of the second handle 28 and the second slider 31, thereby stretching the third telescopic rod 33 and the tension spring 34 to stretch them, wherein the third telescopic rod 33 limits the tension spring 34, thereby ensuring The stability of the tension spring 34 during movement is achieved by driving the second limiting block 32 to slide in the first slot 4 through the second slider 31, wherein the groove shape of the first slot 4 matches the shape of the second slider 31, thereby firmly limiting the second slider 31.

Under the rebound action of the second spring 16, the card block 15 is stuck in the limiting groove 10 in the connecting block 9, thereby limiting the position of the connecting block 9. Four limiting components are provided on each side of the support frame 6. When the anti-slip spike 12 is extended, the card blocks 15 in two of the limiting components will be stuck in the limiting groove 10 and engage with the connecting block 9, while the other two limiting components will rest against the outer wall of the connecting block 9, thereby further limiting the connecting block 9, thereby increasing the stability of the anti-slip spike 12 when it extends out of the detachable sole 2 or is retracted into the detachable sole 2, and can effectively prevent the anti-slip spike 12 from accidentally extending or retracting from the detachable sole 2.

[0046] Example 1:

[0047] When the rescue shoe is used and the anti-slip spikes 12 need to be used to increase the friction, the sliding connecting block 9 can be used to drive the second triangular block 8 to slide in the support frame 6. Under the obstruction of the first triangular block 7, the second triangular block 8 can slide downward on the connecting block 9, and then the second triangular block 8 will squeeze the connecting plate 11 to make it slide in the support frame 6. The connecting plate 11 will squeeze the first spring 13 to make it contract, and drive the anti-slip spikes 12 to slide in the connecting plate 11, and then extend out of the detachable sole 2. At this time, the connecting block 9 squeezes the clamping block 15 while sliding, making it slide in the limiting cylinder 14 and squeeze the second spring 16 to contract. Under the rebound of the second spring 16, the clamping block 15 can be stuck in the limiting groove 10 in the connecting block 9, thereby limiting the position of the connecting block 9;

[0048] When water enters the rescue shoe body 1, during walking, the accumulated water will be discharged through the one-way valve 35 under the action of gravity, thereby effectively preventing the accumulation of water in the rescue shoe body 1 and affecting walking;

[0049] By pressing the first handles 18 on both sides at the same time, under the limit of the first slide rail 19, the second telescopic rod 25 and the second telescopic spring 26 can be squeezed. The first handle 18 will drive the first sliding block 21 to slide on the first slide rail 19 through the first connecting rod 20, thereby squeezing the first telescopic rod 23 and the first telescopic spring 24 to shrink them. The first sliding block 21 will drive the first limiting block 22 to slide in the second slot 5, thereby allowing the detachable sole 2 to be disassembled. When installing the detachable sole 2, first insert the L-shaped block 3 into the groove at the bottom of the rescue shoe body 1, and then insert the first limiting block 22 into the second slot 5, release the first handle 18, and under the rebound of the first telescopic rod 23 and the second telescopic rod 25, the first limiting block 22 can be stuck into the second slot 5, thereby allowing the detachable sole 2 to be installed.

[0050] Example 2:

[0051] When the rescue shoe is used and the anti-slip spikes 12 need to be used to increase the friction, the sliding connecting block 9 can be used to drive the second triangular block 8 to slide in the support frame 6. Under the obstruction of the first triangular block 7, the second triangular block 8 can slide downward on the connecting block 9, and then the second triangular block 8 will squeeze the connecting plate 11 to make it slide in the support frame 6. The connecting plate 11 will squeeze the first spring 13 to make it contract, and drive the anti-slip spikes 12 to slide in the connecting plate 11, and then extend out of the detachable sole 2. At this time, the connecting block 9 squeezes the clamping block 15 while sliding, making it slide in the limiting cylinder 14 and squeeze the second spring 16 to contract. Under the rebound of the second spring 16, the clamping block 15 can be stuck in the limiting groove 10 in the connecting block 9, thereby limiting the position of the connecting block 9;

[0052] When water enters the rescue shoe body 1, during walking, the accumulated water will be discharged through the one-way valve 35 under the action of gravity, thereby effectively preventing the accumulation of water in the rescue shoe body 1 and affecting walking;

[0053] By pulling the second handle 28 at the same time to make it slide on the second slide rail 29, the second handle 28 can pull the second slide block 31 to slide on the second slide rail 29 through the second connecting rod 30, thereby stretching the third telescopic rod 33 and the tension spring 34 to stretch it, and then drive the second limiting block 32 to slide in the first slot 4 through the second slider 31. When the second limiting block 32 slides out of the first slot 4, the detachable sole 2 can be disassembled. When installing the detachable sole 2, similarly, the L-shaped block 3 is now inserted into the rescue shoe body 1, and then the second limiting block 32 is inserted into the first slot 4. Then, the second handle 28 is released.
