Description

Technical Field

[0001] This invention relates to the field of medical equipment delivery technology, specifically a self-protection system for high-altitude delivery of medical equipment boxes. Background Technology

[0002] Medical equipment deployment is an operation that involves dropping equipment from a height to a designated location for rescue and other rescue operations.

[0003] Medical equipment deployment typically involves placing the medical products inside a container, which is then transported by aircraft to a designated location. The container is then slowly lowered and deployed using a parachute, similar to an airdrop. However, because this method relies solely on parachute protection, it is susceptible to crosswinds during descent. Limited by the relatively simple structure of existing deployment containers, it is prone to tipping or tilting, causing the descent trajectory to deviate from the planned path and resulting in errors in the landing point. Furthermore, the container is prone to strong impacts upon contact with the ground, potentially damaging the contents and compromising the safety of the deployment, thus increasing the risk of loss.

[0004] Therefore, a high-altitude deployment self-protection system for medical equipment boxes is proposed to solve the problems mentioned above. Summary of the Invention

The horizontal limiting block is inserted into the rod inside the fixed ring.

[0015] Preferably, an outwardly extending horizontally extending limiting block is provided at the connection between the main push rod and the multi-stage telescopic rod.

[0019] Compared with the prior art, the present invention provides a self-protection system for high-altitude deployment of medical equipment boxes, which has the following beneficial effects:

[0020] 1. The high-altitude delivery self-protection system of this medical equipment box, by setting the side panels to an S-shaped structure, can rotate when subjected to crosswinds from different directions. Based on the cylindrical shape of the delivery box itself, its outer surface can automatically guide the crosswinds and rotate according to the force, effectively preventing the delivery box from tilting under force, thus providing automatic protection when the delivery box is subjected to crosswinds.

[0021] 2. The high-altitude deployment self-protection system of this medical equipment box, with the combined support of push rod, main push rod, auxiliary push rod and push ring, provides support from inside the protective cover to prevent it from being damaged by pressure, and further improves its buffer support strength.

[0022] 3. The high-altitude deployment self-protection system of this medical equipment box, when the protective cover descends and contacts the ground, the protective cover is compressed, and the gas inside moves, turning the protective cover into a circle, increasing its contact area with the ground, ensuring the stability of its landing surface. At the same time, under the buffer of the gas inside the protective cover, the protective cover makes a large-area buffer contact with the ground, dispersing the impact force generated by the airdrop box's descent, and providing buffer protection for the airdrop box's deployment and descent.

[0023] 4. The high-altitude deployment self-protection system of this medical equipment box changes its internal height when the protective cover is compressed from a cone shape to a circle. This changes the height of the internal structure, which in turn pushes the multi-stage telescopic rods from an extended state to a telescopic state. With the combined push of the push rod, main push rod, and auxiliary push rod, the system ensures that the protective cover changes from a cone shape to a circle while its internal structure moves in the same direction, thus ensuring the accuracy and reliability of the protective cover under pressure deformation.

[0024] 5. The high-altitude deployment self-protection system of this medical equipment box, under the limiting support of the extension limiting block, limits the movement range of the main push rod, so that the movement range of the auxiliary push rod is simultaneously limited, and the movement distance of multiple push rings is simultaneously limited, thereby ensuring the controllability of the deformation distance of the protective cover when the push rings move. At the same time, under the length limitation of the main push rod and the auxiliary push rod, the deformation distance of the protective cover is limited, effectively preventing the protective cover from being damaged due to excessive deformation distance.

[0025] 6. The high-altitude deployment self-protection system of this medical equipment box has corresponding threads on the outside of the positioning plug, so that after passing through the horizontal limiting cylinder, it is positioned on one side of the horizontal limiting cylinder with a nut to form a horizontal fixed limiting state. In the vertical positioning state of the vertical fastening component, the positioning plug is doubly positioned to ensure the reliability and stability of its connection effect.

[0026] 7. The high-altitude deployment self-protection system of this medical equipment box allows for the disassembly of the protective cover and its internal structure through the positioning, installation, and removal of the positioning cone, facilitating replacement and maintenance.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example:

[0042] Please see Figure 1 - Figure 12 The high-altitude deployment self-protection system for medical equipment boxes in this embodiment includes 1, and 101 evenly distributed in a ring on the outside of 1. 2 is rotatably arranged above 1, and 3 is fixedly connected to the upper end of 2.

[0043] The lower end of the 1 is provided with a tapered 4, and the 4 is provided with a vertically arranged 28 inside, the 28 being a multi-stage telescopic rod;

[0044] The outermost telescopic end of the 28 is provided with a 29 at its lower end. The 29 is installed on the inner wall of the 4 near the cone angle. The outermost telescopic rod of the 28 is rotatably provided with a 30. The middle telescopic rod of the 28 is rotatably provided with a 32. The fixed support part of the 28 is rotatably provided with a 34. The 34 and the 33 are rotatably provided with a 35. The outer end of the 35 is fixedly connected with a 36.

[0045] The upper end face of the fixed support part of the 28 is fixedly connected to the 27, the upper end of the 27 is provided with the 13, the middle part of the 13 is provided with the 14, and the middle parts of the 13, the 14 and the 27 are simultaneously provided with the 25 for air supply guide support, and the upper end face of the 14 is rotatably provided with a number of 15 distributed in a ring.

[0046] In this invention, by setting the interior of 1 as a limiting space according to the specifications of the medical device and placing certain cushioning materials, such as foam or air bags, the interior of 1 has the effect of protecting the medical device when it is moved from a height, preventing it from being damaged by bumps or collisions during movement. Since the internal treatment method of 1 is a well-known technology in this field, it is not shown in detail in the attached drawings.

[0047] At this time, under the push of the crosswind force, 1 and 2 will rotate relative to each other. With the support of 3, 1 will automatically guide the crosswind on its outer surface during descent based on its cylindrical shape. It will also rotate according to the force, effectively preventing 1 from tilting under the force. This gives 1 an automatic protection effect when it is subjected to crosswind.

[0048] By inflating the interior of 4 under the support of 25, the wind force below is automatically guided when 1 is dropped and landed, ensuring the accuracy of the landing direction of 1. When 4 lands and contacts the ground, it is compressed and the gas inside moves, turning 4 into a circle, increasing its contact area with the ground, and ensuring the stability of its landing surface. At the same time, the gas inside 4 buffers the large area of ​​4 in contact with the ground, dispersing the impact force generated by the landing of 1 and providing buffer protection for the landing of 1.

[0049] When 4 is compressed and changes from a conical shape to a circular shape, its internal height changes accordingly. Pushing 28 gradually moves from an extended state to a contracted state. Under the combined push of 30, 32, and 34, 30 first pushes the bottom of 4 to expand outward, and then 32 and 34 push 36 to move to the side, causing the upper half of the side of 4 to expand. The push of 30 and 36 combined with the pressure on 4 itself ensures that while 4 changes from a conical shape to a circular shape, its interior moves in the same direction, ensuring the accuracy and reliability of 4 under pressure deformation.

[0050] With the combined support of 30, 32, 34, and 36, it provides support from the inside of 4 to prevent it from being damaged by pressure, and further improves its buffer support strength.

[0051] By pressing, moving, and fixing 15, 14 is positioned inside 1, ensuring a stable connection and reliable sealing between 1 and 4.

[0052] The 101 has a uniform S-shape. The 101 is used to provide protection against lateral wind force for the 1, the 4 is used to provide protection against vertical wind force for the 1, and the 3 is used to provide protection against falling speed.

[0053] By setting 101 to an S-shaped structure, it can rotate when subjected to lateral winds from different directions, improving its comprehensive self-protection capabilities for 1. By placing 4 on the side of 1, when the wind from below moves upward through 4, it will pass through the interior of 101. Guided by 101, the wind is pushed laterally or moved upward into the interior of 3, mitigating the impact of the wind and utilizing the wind force to improve the stability and reliability of the device during deployment and descent.

[0054] The outer upper edge region of the 1 is provided with 5, and a 6 for sealing is inserted into the 5. A 7 is fixedly connected to the upper end of the 6, and an 8 for rotational support is provided in the middle of the upper end of the 7.

[0055] The 2 is fitted in the middle of the 8, and the upper and lower ends of the 2 are provided with 9 for guiding and sliding with the inner ball bearings of the 8;

[0056] By pushing 6 into the interior through 5, then covering it with 7, and then using bolts or other fastening components, 5, 6, and 1 are secured to ensure the reliable support of 8. The arrangement of two rings of balls inside 8 provides lubrication support for the relative rotation of 2 and 1, ensuring reliable and stable rotation. By setting the outer ring of 2 to be larger than the side specification of 8, the protection effect of the balls inside 8 is met, preventing impurities from moving into the interior of 8 during the descent process and blocking the lubrication of the balls.

[0057] A 23 is fixedly provided on the outer side of the 13, and the 23 is fixedly provided on the upper edge of the inner wall of the 4. A 12 is provided at the lower end of the 1 for sealing and inserting the 23. The connection between the upper end face of the 4 and the lower end face of the 1 is sealed, and the upper half of the 4 is made of rigid material.

[0058] By setting the upper half of 4 to a rigid material and setting its contact position with 1 to a forced seal, the internal sealing of 4 is ensured when it is connected to 1. Under the plug-in positioning seal of 23 and 12, a tight support is provided from the middle of the device for the connection between 1 and 4, and the reliability of the working position of 4 is ensured.

[0059] The end of 30 away from 29 is rotatably connected to the inner wall of 4, and the outer side of the end of 30 near 29 is fixedly connected to 31, which is inserted into the rod inside 29.

[0060] Driven by 30, 4 can move in an arc shape, and 29 gradually moves to the position where 30 and 4 are in contact. This causes the bottom of 4 to contract towards the middle in sync, so that 31 gradually inserts into the inner rod of 29, forming a limiting effect of 29 on 31. This prevents 30 from contracting too much inward, which would cause 4 to deform too severely and fail to provide cushioning support.

[0061] A horizontally extending 33 is provided at the connection between 32 and 28. The 33 is used to limit the rotation of 32. The 35 is located in the middle of 32 and 34, and the 35 and 36 are arranged in a ring on the outside of 28.

[0062] With the limiting support of 33, the movement range of 32 is limited, so that the movement range of 34 is simultaneously limited, and the movement distance of multiple 36 is simultaneously limited, thereby ensuring the controllability of the deformation distance of 36 moving 4. At the same time, under the length limit of 32 and 34, the deformation of 4 is limited by distance, effectively preventing the situation of 4 deformation distance being too large and causing damage, and ensuring the reliability and safety of 4 in deformation buffer.

[0063] The lower end of the 1 has a frustoconical groove through which it is inserted into the 14. The 14 is inserted into the interior of the 1. The interior of the 27 has several uniformly annularly distributed through grooves. The 25 communicates with the through grooves, and the 26 is provided in the middle of the 25. The middle of the 25 and the middle of the 14 are simultaneously connected by a threaded seal with a 24.

[0064] By using an external gas injection device mechanism to inject gas into 4 through 25 and 27, and guided by multiple oblique holes in 27, the gas can be injected evenly into the interior of 4 from multiple directions. Under the anti-reverse action of 26, the gas inside 4 is effectively prevented from flowing outward. After the gas injection is completed, by turning 24, it is synchronously connected and sealed with the interior of 25 and 14, further ensuring the airtightness of the gas inside 4.

[0065] A plurality of 21s are vertically arranged on the outer side of the 23. The 21s are inserted into the interior of the 1. A plurality of 22s are arranged on the lower surface of the interior of the 1. The number of 22s, 15s, and 21s are the same. The 15s are located above the middle of the 22s. The end of the 15 away from the 14 is rotatably connected to the 16. The 16s are rotatably connected to the truncated cone-shaped 11. The outer end face of the 11s is fixedly connected to the 18. The 17s and the 18s are simultaneously inserted into the 21s. The 18s are inserted into the 20s. The outer end of the 18s is threadedly connected to the 19. The 19s and the 20s are both installed on the bottom surface of the interior of the 1.

[0066] A 10 is provided above the 14, and an 11 is provided on the inner wall side of the 1. The 11 is located below the 10, and the 10 is fixed to the 11 by an outer bolt.

[0067] When installing 4 and 14, insert 14 into 1, then rotate 15 until the connection between 15 and 14 is achieved. Then, with the support of 22, make the two ends of 15 form a seesaw principle. By pressing the outer end of 15, 14 moves upward. Then, insert 17 and 18 into 21 for positioning, forming a fixed connection between 16, 17, and 15. Since the insertion position of 17 and 21 is lower than the height of 22, ensure that the outer side of 15 is continuously pressed down. Then, with the fastening of 19, position 18 to ensure the overall connection and fixation of 18, 16, and 15.

[0068] Based on the tapered design of 17 itself, the contact area between 17 and 21 gradually increases while ensuring the tightness of the connection. This ensures that 15 is stably lifted and fixed to 14. By setting corresponding threads on the outside of 18, after passing through 20, it is positioned on one side of 20 with a nut, forming a horizontal fixed limit state. In the vertical positioning state of 19, 18 is doubly positioned, ensuring the reliability and stability of its connection effect.

[0069] Finally, by fixing the position of 10 above 14, an isolation and protection effect is formed, which does not affect the normal placement of medical equipment inside 1 and ensures the normal use of the device.

[0070] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
