Description

Technical Field

[0001] This utility model relates to the field of rescue device technology, specifically to a sliding safety self-rescue belt. Background Technology

[0002] Mine safety is of paramount importance to industrial development. Underground working environments are complex and unpredictable, making the self-rescue protective belts carried by miners crucial life-saving equipment in the event of a disaster. Currently widely used self-rescue protective belts typically integrate various life-saving devices such as self-rescue devices, first-aid supplies, and emergency communication tools. These items are carried through various pockets fixed around the belt's circumference, aiming to provide miners with immediate safety assurance.

[0003] However, existing technologies generally employ a fixed storage design. The bag containing self-rescue items is secured to a fixed position on a flexible belt via hooks. Once the placement of the items is determined, it is inconvenient to adjust, resulting in poor mobility. Especially in emergencies, when operators need to retrieve items located to their side or behind them, obstructed vision and limited movement often force them to twist their bodies or repeatedly grope to reach them, which is not only inefficient but may also cause them to miss opportunities for self-rescue. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: A sliding safety self-rescue belt includes a rigid outer frame surrounding the waist, and an adaptive annular bladder fixedly disposed inside the rigid outer frame. The adaptive annular bladder expands by filling with a fluid medium to fix it to the waist. A sliding track is provided on the rigid outer frame along the enclosure path of the rigid outer frame, and multiple item racks are slidably arranged in the sliding track; In this process, multiple shelves move to the front by pushing against each other to create a coordinated displacement.

[0005] As a preferred embodiment of this utility model, a plurality of positioning holes are arranged on the sliding track along the sliding trajectory of the shelf, and a positioning pin that matches and is inserted into the positioning hole is slidably provided on the shelf longitudinally. The shelf is fixed in position by inserting the positioning pin into the positioning hole.

[0006] In a preferred embodiment of this utility model, the positioning hole is arranged on the bottom surface of the sliding track, and a top post is correspondingly provided below the positioning hole. The top post is fixedly mounted on the slide plate, and the slide plate is longitudinally slidably mounted on the bottom of the rigid outer frame. The maximum sliding stroke of the slide plate is achieved when the top surface of the top post is inserted into the positioning hole and remains flush with the bottom surface of the sliding track.

[0007] In a preferred embodiment of this utility model, when the skateboard slides to its maximum sliding stroke, it is fixedly connected to the rigid outer frame via a movable connector.

[0008] As a preferred embodiment of this utility model, the rigid outer frame includes a left frame and a right frame, which are connected to each other by a movable plug-in structure. Two sliding plates are provided on each of the left frame and the right frame, and the two sliding plates are symmetrically arranged along the axis of symmetry of the left frame / the right frame.

[0009] In a preferred embodiment of this utility model, the fluid medium is pure water or oxygen, and the adaptive annular bladder is provided with an inlet hole and an outlet hole, and an extension tube is connected to the outlet hole for supplying water or gas to the human body.

[0010] As a preferred embodiment of this utility model, the top of the adaptive annular bladder is provided as a rigid cover, and the rigid cover is recessed downward to form an arc-shaped groove for receiving the extension tube.

[0011] Compared with the prior art, this utility model has the following advantages: This invention features a sliding shelf along the enclosure of a rigid frame. Operators can simply slide the shelf in front of them to push the target item into a visible and easily accessible area using physical transmission, significantly improving efficiency and accuracy in blind operation. Furthermore, the added fixing structure prevents the shelf from sliding freely during normal operation, ensuring the stability and reliability of the equipment stored on it. The quick-release mechanism with a top column provides a fast emergency response and a user-friendly operating experience, significantly enhancing the practicality and reliability of mine safety equipment.

[0015] 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.

[0016] like Figure 1 As shown, this utility model provides a sliding safety self-rescue belt, including a rigid outer frame 1 that surrounds the waist of the user. The rigid outer frame 1 can be made of high-strength plastic or composite material to provide structural support strength and maintain a specific annular or near-annular shape around the operator's waist. Inside the rigid outer frame 1, an adaptive annular bladder 2 is fixedly installed by adhesive or buckles. This adaptive annular bladder 2 is made of a flexible, airtight material (such as rubber) and has inflation / liquid holes (not shown in the figure) with inflation / liquid valves. Through these valves, a fluid medium (such as air or liquid) can be injected into the bladder using a manual air pump or similar tool, causing it to expand and deform, thus tightly fitting the waist of different operators. This achieves rapid device fixation and greatly improves wearing comfort and versatility, effectively solving the problem of unstable fixation or discomfort caused by differences in body shape.

[0017] A continuous sliding track 3 is machined or molded along the entire annular enclosure of the rigid outer frame 1. Multiple independent shelf units 4 are slidably arranged within this sliding track 3. Each shelf unit 4 may be equipped with slots, elastic bands, or Velcro of different sizes for securely and systematically storing various self-rescue equipment such as self-rescue devices, first-aid medicines, emergency lights, and whistles. The multiple shelf units 4 are linked together by mutual pushing, creating a coordinated displacement that moves the shelf unit 4 from the rear to the front.

[0018] Specifically, such as Figure 1As shown, multiple shelves 4 are arranged end-to-end within the sliding track 3. When an operator needs to retrieve an item located behind (such as behind the user), they only need to push the foremost shelf 4 along the track from a convenient position in front of their body. This shelf 4 will then push the next one adjacent to it, and so on, forming a chain-like linkage displacement. This allows the target shelf 4 and the items it carries to be moved smoothly and accurately to an area in front of the user with a good field of vision and easy access for both hands. This greatly improves the efficiency and success rate of self-rescue in emergency situations where visibility is obstructed and the user is nervous.

[0019] Furthermore, to ensure that the shelf 4 does not accidentally slide due to body movement or slight collisions during normal downhole operations, and to maintain the stability of the overall device and the orderly storage of items, this invention incorporates a positioning mechanism. Specifically, multiple positioning holes 5 are provided along the sliding trajectory of the shelf 4 on the sliding track 3. At the bottom of each shelf 4, a positioning pin 6 is slidably installed longitudinally (i.e., perpendicular to the sliding direction). This positioning pin 6 can be provided with a downward biasing force by a built-in spring (not shown in the figure), giving it a tendency to insert into the positioning hole 5 under normal conditions, or it can be limited to a slidable position at the bottom of the shelf 4. When the shelf 4 slides to a specific position, the positioning pin 6 automatically falls into the positioning hole 5 at that position under the action of the spring force or its own gravity. Through the insertion and engagement of the pin and the hole, the position of the shelf 4 is fixed, preventing arbitrary sliding. This mechanical positioning method is simple in structure, low in cost, has good environmental adaptability, and is highly practical.

[0020] Additionally, when it is necessary to release the positioning to slide the shelf 4, such as Figure 2 and Figure 3 As shown, the positioning hole 5 is arranged on the bottom surface of the sliding track 3, and the top post 7 is correspondingly arranged below the positioning hole 5. The top post 7 is fixedly installed on the slide plate 8, which is longitudinally slidably set in the bottom frame of the rigid outer frame 1 through a structure such as a sliding groove. The slide plate 8 can be equipped with sliders at both ends or on its sides, and the inner wall of the rigid outer frame 1 is equipped with a sliding groove, thereby forming a limiting vertical sliding connection. When the operator needs to unlock, he only needs to push the slide plate 8 upward. The upward sliding of the slide plate 8 will drive the top post 7 to rise synchronously. The top of the top post 7 will then be inserted into the positioning hole 5 from below, thereby pushing the positioning pin 6, which was originally inserted in the hole, upward, so that it is disengaged from the positioning hole 5, and the shelf 4 is unlocked and can slide freely. Among them, when the top surface of the top post 7 rises to be flush with the bottom surface of the sliding track 3, the maximum sliding stroke of the slide plate 8 is reached. This design ensures that the positioning pin 6 can be fully pushed out, and avoids the top post 7 protruding too much and hindering the smooth movement of the shelf 4. Furthermore, the unlocking method, which involves pushing upwards from the bottom of the device, is intuitive and convenient, and can be easily implemented even when wearing heavy work clothes or gloves.

[0021] To further optimize the ease of unlocking and avoid the need to continuously hold the slide plate 8 in its raised state after pushing it, this invention provides a movable connector 9 at the position where the slide plate 8 slides to its maximum travel (i.e., the top surface of the top post 7 is flush with the bottom surface of the track). This connector can be a magnetic structure, for example, embedding a permanent magnet in the slide plate 8 and embedding an iron sheet or another permanent magnet of opposite polarity in the corresponding position on the rigid outer frame 1. When the slide plate 8 is pushed to the top, the magnetic force attracts it and automatically holds it in that position, thereby achieving the locking of the unlocked state. Alternatively, a spring-loaded latch structure can be used. When the slide plate 8 rises to the top, the latch clicks into the groove of the rigid outer frame 1 to secure it. To reset, simply pull the slide plate 8 downwards with a little force to disengage the latch.

[0022] In this device, the rigid outer frame 1 surrounding the waist can be set in various ways. For example, it can be a whole structure that is worn by a person to the waist, or it can be assembled and set on the outside of the waist by splicing multiple pieces.

[0023] Furthermore, as a preferred embodiment, such as Figure 5 As shown, the rigid outer frame 1 adopts a split design, specifically including a left frame 10 and a right frame 11 located on either side of the user's body. The left frame 10 and the right frame 11 are connected to each other at the middle of the front and back of the body through a movable plug-in structure 12 (such as a male and female slot engagement or a pawl engagement), making the entire outer frame easy to put on and take off. Furthermore, each of the left frame 10 and the right frame 11 is provided with two slides 8, which are symmetrically arranged along the axis of symmetry of the left frame 10 / right frame 11.

[0024] These four sliding plates 8 independently control the unlocking of the shelf 4 positioning pins 6 within their respective arc-shaped sections. Compared to using an extra-long sliding plate 8 that wraps around the entire waist, this design has several advantages: First, it greatly shortens the length of a single sliding plate 8, reducing processing difficulty and cost; second, the operator can unlock a local shelf 4 by pushing the short sliding plate 8 within a small range, requiring less operating force and responding quickly; third, the symmetrical arrangement and short span design ensure even lifting force, effectively avoiding the risk of deformation, tilting, or jamming that may occur with the long sliding plate 8 during operation, ensuring the reliability and smoothness of the unlocking action; fourth, it conforms to ergonomic design, with the four sliding plates 8 located on the front and rear sides of the body, which can be lifted by simply lifting with both hands, making operation simple and convenient. Compared to a single sliding plate 8, two sliding plates 8 (covering the bottom of the left frame 10 and the bottom of the right frame 11 respectively), or multiple sliding plates 8 (one sliding plate 8 for each positioning hole 5), it offers higher operational efficiency, practicality, accuracy, and reliability.

[0025] In addition, the fluid medium is pure water or oxygen. The adaptive annular bladder 2 is equipped with an inlet and an outlet, with an extension tube 13 connected to the outlet for supplying water or oxygen to the human body. Pure water or oxygen are particularly beneficial in emergency self-rescue scenarios in mines. If filled with pure water, the annular bladder, after inflation, not only provides fixation but also forms a water-storage bladder around the waist. An extension tube 13 is connected to the outlet (connected to a normally closed valve) on the bladder. Figure 2 and Figure 4 As shown, in extreme emergency situations (such as being trapped and awaiting rescue), the operator can open the valve and drink the purified water inside the drinking bag through the extension tube 13. If filled with oxygen, the annular bag can serve as an emergency backup oxygen source. Similarly, through the drain port and extension tube 13, respiratory support can be provided to trapped personnel or injured individuals requiring additional oxygen. This transforms the adaptive annular bag 2 from a simple fixing and cushioning component into a multifunctional life support module, greatly enhancing the overall effectiveness of this self-rescue and protective device.

[0026] Furthermore, to further optimize the storage of the extension tube 13 and prevent it from being caught or contaminated while hanging haphazardly, this invention sets a rigid cap 14 on the top of the adaptive annular bladder 2. This rigid cap 14 can be integrally formed with or securely connected to the rigid outer frame 1, thereby improving the fixing strength of the adaptive annular bladder 2. An arc-shaped groove 15 is formed by a downward (i.e., towards the inside of the annular bladder) indentation on the rigid cap 14. The shape of this groove matches the coiled extension tube 13. When not in use, the extension tube 13 can be neatly coiled and hidden within this arc-shaped groove 15. This design maintains the flatness of the device's exterior, avoids protrusions, and improves operational safety. Simultaneously, it provides good protection for the extension tube 13, preventing it from being worn, flattened, or contaminated, ensuring that it can be quickly removed and remains fully functional when needed.

[0027] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
