Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment placement, in particular to a self-protection system for high-altitude placement of medical equipment boxes. Background Art

[0002] Medical equipment delivery is an operation that involves dropping equipment from a high altitude to a designated location for rescue and other actions.

[0003] Medical equipment delivery usually involves placing the medical products inside a box, which is then transported to a designated location by airplane. Under the cushioning of a parachute, a slow descent is achieved, similar to the operation of an airdrop. However, since this delivery method only relies on the cushioning protection of a parachute, it is easily affected by side winds during its descent. Limited by the relatively simple box structure of existing delivery boxes, it is prone to rollover or tilt, causing the falling trajectory to deviate from the expected trajectory and resulting in errors in the landing point. In addition, strong collisions are easily generated when the box contacts the ground, causing damage to the items inside, affecting the safety of its delivery and easily causing losses.

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

[0020] 1. The self-protection system for high-altitude delivery of medical equipment boxes sets the side panels into an S-shaped structure so that it can rotate when subjected to side winds from different directions. Based on the cylindrical setting of the airdrop box itself, its outer surface can automatically divert the side wind and produce a rotation effect according to the force conditions, effectively preventing the airdrop box from tilting due to force, so that the airdrop box itself has an automatic protection effect when subjected to side winds.

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

[0022] 3. The medical equipment box has a self-protection system for high-altitude delivery. When the protective cover lands and contacts the ground, the protective cover is compressed, and the gas inside it moves, turning the protective cover into a round shape, increasing its contact area with the ground and ensuring the stability of its landing surface. At the same time, under the buffering of the gas inside the protective cover, the protective cover has a large area of buffering contact with the ground, dispersing the impact force generated by the landing of the airdrop box and providing buffering protection for the landing of the airdrop box.

[0023] 4. The self-protection system of the medical equipment box for high-altitude deployment, when the protective cover changes from conical to circular under pressure, its internal height changes accordingly, pushing the multi-stage telescopic rod to gradually move from the extended state to the telescopic state. Under the combined push of the push rod, main push rod, and auxiliary push rod, the protective cover changes from conical to circular while its interior moves in the same direction, ensuring that the protective cover is accurately and reliably deformed under pressure.

[0024] 5. The self-protection system for high-altitude delivery of the medical equipment box limits the moving range of the main push rod under the limit support of the extended limit block, so that the moving range of the auxiliary push rod is synchronously limited, and the moving distance of multiple push rings is synchronously limited, thereby ensuring that the deformation distance of the push ring moving protective cover is controllable. At the same time, under the length limit of the main push rod and the auxiliary push rod, a distance limit is provided for the deformation of the protective cover, effectively preventing the protective cover from being damaged due to excessive deformation distance.

[0025] 6. The self-protection system for high-altitude placement of the medical equipment box is equipped with corresponding threads on the outside of the positioning plug, so that after passing through the horizontal limit cylinder, it is positioned on one side of the horizontal limit cylinder using a nut, forming a horizontal fixed limit state, and when the vertical fastening component is in the vertical positioning state, the positioning plug is doubly positioned to ensure the reliability and stability of its connection effect.

[0026] 7. The high-altitude self-protection system of the medical equipment box can be installed and disassembled through the positioning cone, so that the protective cover and its internal structure can be disassembled, which is convenient for replacement and maintenance.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example:

[0042] See also Figure 1 - Figure 12 The medical equipment box high-altitude delivery self-protection system in this embodiment includes 1, and 101 evenly distributed on the outside of the 1 in a ring shape, 2 is rotatably provided above the 1, and 3 is fixedly connected to the upper end of the 2;

[0043] The lower end of the 1 is provided with a conical 4, and the interior of the 4 is vertically provided with 28, which is a multi-stage telescopic rod;

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

[0045] The upper end surface of the fixed support portion 28 is fixedly connected to 27, the upper end of the 27 is provided with 13, the middle of the 13 is provided with 14, the 13, the 14 and the middle of the 27 are simultaneously provided with 25 for air supply guide support, and the upper end surface of the 14 is rotatably provided with a plurality of 15 distributed in an annular shape;

[0046] Among them, by setting the interior of 1 into a limited space according to the specifications of the medical equipment and placing certain cushioning materials, such as foam, inflatable bags, etc., the interior of 1 can provide protection for the medical equipment during high-altitude deployment and movement, preventing it from being damaged by bumps or collisions during movement. Since the processing method of the interior of 1 is a well-known technology in this field, it is not drawn in detail in the drawings;

[0047] At this time, under the push of the lateral wind force, 1 and 2 rotate relative to each other, and under the support of 3, during the descent process, 1, based on its own cylindrical setting, its outer surface can automatically guide the lateral wind and produce a rotation effect according to the force, effectively preventing 1 from tilting due to the force, so that 1 itself has an automatic protection effect when it is subjected to lateral wind;

[0048] Under the support of 25, air is inflated into 4, so that when 1 is dropped and landed, the wind force below is automatically diverted to ensure the accurate landing direction of 1. When 4 lands and contacts the ground, 4 is compressed, and the air inside it moves, turning 4 into a round shape, increasing its contact area with the ground and ensuring the stability of its landing surface. At the same time, under the cushioning of the air inside 4, 4 has a large area of buffering contact with the ground, dispersing the impact force generated by the landing of 1, and providing cushioning protection for the landing of 1.

[0049] When 4 changes from a conical shape to a circular shape under pressure, its internal height changes accordingly, pushing 28 from an extended state to a telescopic 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 sideways, causing the upper half of 4 to expand. The push of 30 and 36 and the pressure of 4 itself are combined to ensure that 4 changes from a conical shape to a circular shape while its interior moves in the same direction, ensuring that 4 is accurately and reliably deformed under pressure.

[0050] And under the combined support of 30, 32, 34, and 36, a support effect is provided from the inside of 4 to prevent it from being damaged by pressure, and further improve its buffer support strength;

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

[0052] Said 101 is in a uniform S-shape, said 101 is used to provide lateral wind protection for said 1, said 4 is used to provide vertical wind protection for said 1, and said 3 is used to provide falling speed buffer protection for said 1;

[0053] By setting 101 as an S-shaped structure, it can rotate when it is subjected to side winds from different directions, thereby improving the comprehensiveness of its self-protection for 1. By setting 4 on the side of 1, when the wind from below moves upward through 4 for the next time, it will pass through the inside of 101. Under the guidance of 101, the wind is pushed sideways or moves upward to the inside of 3, thereby alleviating the impact of wind force and utilizing wind force to improve the stability and reliability of the device during the deployment and landing process.

[0054] The outer upper edge area of the said 1 is provided with 5, the said 5 is inserted with 6 for sealing, the upper end of the said 6 is fixedly connected with 7, and the middle part of the upper end of the said 7 is provided with 8 for rotation support;

[0055] The 2 sleeves are arranged in the middle of the 8, and the upper and lower ends of the 2 are provided with 9 which slides with the ball guide in the 8;

[0056] By pushing 6 to the inside through 5, then covering 7, and then using bolts or other fastening parts to fasten 5, 6, and 1 stably, it is ensured that 8 is supported firmly, and by setting up two circles of balls in the upper and lower circles in 8, lubrication support is provided for the relative rotation of 2 and 1, ensuring that their rotation is reliable and stable, and by setting the outer ring of 2 to be larger than the side specification of 8, the protection effect of the balls in 8 is met, preventing impurities from moving into 8 during the falling process and blocking the lubrication of the balls.

[0057] The outer side of the 13 is fixedly provided with 23, and the 23 is fixedly provided at the upper edge of the inner wall of the 4. The lower end of the 1 is provided with 12 for sealing and plugging the 23. The connection between the upper end surface of the 4 and the lower end surface of the 1 is sealed, and the upper half of the 4 is made of hard material;

[0058] By setting the upper half of 4 to a hard material and setting the contact position with 1 to a forced seal, the internal sealing of 4 is ensured when connected with 1, and under the plug-in positioning seal of 23 and 12, the connection between 1 and 4 is provided with fastening support from the middle of the device, and the reliability of the action position of 4 is ensured.

[0059] The end of the 30 away from the 29 is rotatably connected to the inner wall of the 4, and the outer side of the end of the 30 close to the 29 is fixedly connected to 31, and the 31 is plugged into the rod inside the 29;

[0060] Under the push of 30, it is ensured that 4 can move in an arc shape, and 29 is gradually moved to the contact position between 30 and 4, so that the bottom of 4 is synchronously contracted toward the middle, so that 31 is gradually plugged into the inner rod of 29, forming a limiting effect of 29 on 31, which can prevent 30 from contracting inward too much, resulting in excessive deformation of 4 and failure to provide buffer support.

[0061] The connection between 32 and 28 is provided with 33 extending outward horizontally, 33 is used to limit the rotation of 32, 35 is located in the middle of 32 and 34, and 35 and 36 are distributed in a ring shape on the outside of 28;

[0062] Under the limit support of 33, the moving range of 32 is limited, so that the moving range of 34 is limited synchronously, and the moving distances of multiple 36 are limited synchronously, thereby ensuring that the deformation distance of 36 moving 4 is controllable. At the same time, under the length limit of 32 and 34, a distance limit is provided for the deformation of 4, effectively preventing the situation where the deformation distance of 4 is too large and damage is caused, ensuring the reliability and safety of 4 in deformation buffering.

[0063] The lower end of the 1 is penetrated by a frustum-shaped groove for plugging with the 14, the 14 is plugged into the interior of the 1, the interior of the 27 is penetrated by a plurality of evenly distributed annular through grooves, the 25 is connected to the through grooves, and the middle of the 25 is provided with 26, the middle of the 25 and the middle of the 14 are simultaneously threaded and sealed with 24;

[0064] By using the external gas filling device mechanism to inject gas into 4 through 25 and 27, and under the guidance of multiple inclined holes in 27, the gas can be evenly injected into 4 from multiple directions, and under the anti-return effect of 26, the gas inside 4 can be effectively prevented from flowing outward. After the gas injection is completed, by twisting 24, it is synchronously connected and sealed with the inside of 25 and the inside of 14, further ensuring the sealing of the gas in 4.

[0065] The outer side of the 23 is vertically provided with a plurality of 21, and the 21 is plugged into the interior of the 1. The lower surface of the interior of the 1 is provided with a plurality of 22. The number of the 22, the 15, and the 21 is the same. The 15 is located above the middle of the 22. The end of the 15 away from the 14 is rotatably connected to the 16. The 16 is rotatably connected to the frustum-shaped 11. The outer end surface of the 11 is fixedly connected to the 18. The 17 and the 18 are simultaneously plugged into the 21. The 18 is plugged with 20. The outer end of the 18 is threadedly connected to 19. The 19 and the 20 are both installed on the inner bottom surface of the 1.

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

[0067] When installing 4 and 14, plug 14 into 1, then rotate 15 until the connection between 15 and 14 is achieved through rotation. Then, with the support of 22, the two ends of 15 form a seesaw principle. By pressing the outer end of 15, 14 moves upward, and then 17, 18 and 21 are plugged into position to form a fixed connection between 16, 17 and 15. Since the plug-in position of 17 and 21 is lower than the height of 22, it is ensured that the outer side of 15 is continuously pressed down. Then, with the tightening of 19, 18 is positioned to ensure the fixation of the overall connection between 18, 16 and 15.

[0068] Based on the conical setting of 17 itself, the contact area between 17 and 21 gradually increases while ensuring the tightness of the connection, ensuring that 15 is stably lifted and fixed to 14 at this time, and by providing corresponding threads on the outside of 18, after passing through 20, it is positioned on the side of 20 using a nut, forming a horizontal fixed limit state, and when 19 is in the vertical positioning state, 18 is doubly positioned, ensuring its reliable and stable connection effect;

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

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