Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a portable anti-collision and shock-resistant field nursing box. BACKGROUND

[0002] The portable field nursing box is a key equipment for storing and transporting precision medical equipment, medicines and first aid supplies in complex environments such as field medical treatment and field rescue. Its use scenarios are often accompanied by bumpy transportation, accidental collision, rugged terrain and other complex working conditions. During battlefield maneuvering, field walking transportation or emergency response, the nursing box needs to frequently withstand impacts and vibrations from different directions. If the protection performance is insufficient, the precision items such as syringes, reagents and electronic diagnostic devices inside the box are easily damaged, which directly affects the efficiency of first aid and the ability of medical support. Therefore, the anti-collision and shock resistance of the nursing box is highly required, especially in terms of impact energy absorption and internal item fixation stability, which needs to meet the reliable protection requirements in complex environments.

[0003] The anti-collision and shock resistance design of the existing portable nursing box mainly relies on single buffer material or simple mechanical structure to achieve protection function. In terms of buffer structure, EVA foam, rubber pad and other elastic materials are usually used as internal filling to absorb vibration energy through material deformation; external protection mainly uses thickened shell or right-angle corner to resist collision impact by relying on structural stiffness. In terms of item fixation, foam slots are mainly used to adaptively fix items by shape, and material friction is used to limit item shaking.

[0004] However, due to the limited absorption capacity of single material buffer to high-frequency impact and large impact force, the material deformation range is fixed, resulting in short buffer stroke, and the impact energy is difficult to be fully dissipated, which easily causes damage to internal items due to excessive instantaneous impact force, thus it is difficult to adapt to the variable impact load in field environment.

[0005] Therefore, in view of the above problems, a portable anti-collision and shock-resistant field nursing box is proposed to solve the above problems. SUMMARY

[0006] In order to make up for the above shortcomings, the present application provides a portable anti-collision and shock-resistant field nursing box, which aims to improve the problem that the buffer structure of part of the field nursing box in the prior art is difficult to adapt to the variable impact load in the field environment due to single material design.

[0007] In order to achieve the above purpose, the present application adopts the following technical scheme: A portable anti-collision and shock-resistant field nursing box, comprising a box body, a box lock is fixedly connected to the outer surface of the box body; a trigger mechanism is arranged around the box body, and a buffer mechanism is arranged on both sides of the box body, and the trigger mechanism and the buffer mechanism are drivingly connected; The trigger mechanism comprises a trigger plate movably connected to the outer side wall of the box body, a reaction piece built in the inner wall of the box body, and a connecting plate having one end in contact with the outer end of the reaction piece and the other end connected to the buffer mechanism; The buffer mechanism comprises an outer cylinder, a contact outer ring movably connected to the outer side of the outer cylinder, an inner core embedded in the inner part of the outer cylinder, a honeycomb groove formed on the outer surface of the inner core, and a corrugated spring layer filled between the inner core and the outer cylinder. Further description of the above technical solution: The trigger plate comprises a smooth plate body having a circular through hole formed on the surface thereof, and an extrusion strip protruding from the edge of the smooth plate body. Further description of the above technical solution: The reaction piece comprises a double-end sleeve fixed to the inner wall of the box body, a top column penetrating the double-end sleeve, and an ejection spring sleeved on the outer side of the top column, with the two ends of the ejection spring respectively abutting against the rear end of the top column and the inner part of the double-end sleeve. Further description of the above technical solution: One end of the outer cylinder is fixedly connected to the connecting plate, and the other end is movably connected to the inner side wall of the box body, the contact outer ring is attached to the outer side wall of the outer cylinder, and the honeycomb groove is distributed along the circumference of the inner core. Further description of the above technical solution: The corrugated spring layer has a continuous wave structure, is arranged in a stacked manner along the axial direction of the inner core, and has two ends respectively abutting against the inner wall of the outer cylinder and the outer wall of the inner core. Further description of the above technical solution: The inner part of the box body is embedded with a bearing foam plate, the upper part of the bearing foam plate is covered with a breathable foam cover detachably connected to the inner side wall of the box body, and the top part of the bearing foam plate and the bottom part of the breathable foam cover are both provided with a clamping groove for storing articles. Further description of the above technical solution: The surface of the breathable foam cover is provided with a breathable hole. Further description of the above technical solution: The trigger plate is movably connected to the outer side wall of the box body through a sliding fit structure and can be displaced inward along the lateral direction of the box body.

[0008] The present application has the following advantages: 1. In the present application, through the synergistic effect of the outer cylinder, the contact outer ring, the inner core, the honeycomb groove and the corrugated spring layer of the buffer mechanism, the external impact is first accepted by the contact outer ring and preliminarily buffered, the outer cylinder drives the inner core to move relatively under the transmission of force, so that the continuous wave-shaped corrugated spring layer filled between the two is extruded to generate deformation and store power, and the honeycomb groove distributed in the circumferential direction on the outer surface of the inner core is deformed in structure with the reduction of the interval, and the impact force is further dispersed through the plastic deformation of the honeycomb unit. Through the superposition effect of multiple physical buffer structures, the impact energy is realized from contact to absorption in a step-by-step degradation, and the shock protection effect of the nursing box on internal precision medical equipment and medicines is improved.

[0009] 2. In the present application, through the linkage cooperation of the trigger plate, the reaction piece and the connecting plate of the trigger mechanism, the trigger plate is displaced inward along the lateral sliding fitting structure of the box body when impacted by the outside, the circular through hole on the surface thereof is accurately aligned with the top post in the double-head sleeve of the reaction piece, the ejection spring in the compressed state releases the elastic force to push the top post to move outward, the top post efficiently transmits the force to the buffer mechanism through the connecting plate, and the outer cylinder is stretched out of the box body. This process prolongs the buffer distance, so that the impact energy is absorbed by the corrugated spring layer and the honeycomb groove in stages in a longer stroke, the buffer path is actively prolonged through preliminary impact, and therefore the overall anti-collision and shock resistance of the nursing box in complex field environment is enhanced.

[0014] The trigger mechanism 3 comprises a trigger plate 31 movably connected with the outer side wall of the box 1, directly contacting external impact and converting impact signals into mechanical action to start the protection process through its displacement; the trigger plate 31 is movably connected with the outer side wall of the box 1 through a sliding fit structure, reducing the friction resistance during displacement to ensure rapid inward movement when impacted; it can be displaced inward along the lateral direction of the box 1, and this displacement changes the relative position with the reaction piece 32, creating conditions for the expansion of the buffer mechanism 4. The trigger plate 31 comprises a smooth plate body 311, which is smooth on the surface to reduce friction with the outer side wall of the box 1, and also serves as a mounting carrier for the circular through hole 312 and the extrusion strip 313; the surface of the smooth plate body 311 is provided with a circular through hole 312, which is aligned with the top column 322 of the reaction piece 32 when the trigger plate 31 is displaced to a certain position, providing a channel for the movement of the top column 322 to switch the locking state; the edge of the smooth plate body 311 is provided with an extrusion strip 313, which extrudes the air-permeable foam cover 5 and the bearing foam plate 7 when the trigger plate 31 is displaced inward, enhancing the clamping and fixing of the articles to reduce shaking; the reaction piece 32 is built into the inner wall of the box 1, installed on the inner wall of the box 1 to convert the displacement signal of the trigger plate 31 into mechanical thrust, driving the expansion of the buffer mechanism 4; the reaction piece 32 comprises a double-head sleeve 321 fixed to the inner wall of the box 1, providing guidance and support for the movement of the top column 322, limiting the axial movement of the top column 322 to avoid deviation affecting power transmission; the top column 322 is provided in the double-head sleeve 321 and moves axially under the action of the ejector spring 323, converting elastic potential energy into mechanical thrust and transmitting it to the buffer mechanism 4; and the ejector spring 323 is sleeved outside the top column 322, initially in a compressed state to store elastic potential energy, and releases energy to push the top column 322 to move after the through hole is aligned with the top column 322, providing a power source for the expansion of the buffer mechanism 4; and the two ends of the ejector spring 323 abut against the rear end of the top column 322 and the inside of the double-head sleeve 321 respectively, ensuring that the spring compression force effectively acts on the top column 322, and the fixed end is fixed through the double-head sleeve 321 to maintain stability during compression and expansion; one end contacts the outer end of the reaction piece 32, and the other end is connected to the connecting plate 33 of the buffer mechanism 4, serving as a force transmission medium to transmit the thrust of the top column 322 to the buffer mechanism 4, driving it to switch from the storage state to the expanded state.

[0015] The buffer mechanism 4 comprises an outer cylinder 401 as a main support structure of the buffer mechanism 4, providing a mounting space for internal components, extending outward to form a protective length when unfolded to extend the buffer path; a contact outer ring 402 slidingly connected to the outer side of the outer cylinder 401, moving synchronously with the outer cylinder 401, serving as the first component to contact external impact after the buffer mechanism 4 is unfolded, and preliminarily buffering the impact by relative sliding with the outer cylinder 401; an inner core 403 embedded in the inner part of the outer cylinder 401, forming a relative movement structure with the outer cylinder 401, moving with the outer cylinder 401 under the action of impact, and pressing the corrugated spring layer 405 and the honeycomb groove 404 to trigger the deformation of the buffer structure to absorb energy; the honeycomb groove 404 is opened on the outer surface of the inner core 403 and is distributed circumferentially along the inner core 403, and the structure deforms when the relative movement time interval between the inner core 403 and the outer cylinder 401 is reduced, and the impact energy is dispersed by plastic deformation of the honeycomb unit to reduce local stress; the corrugated spring layer 405 is filled between the inner core 403 and the outer cylinder 401, and the elastic deformation is generated when the corrugated spring layer 405 is continuously pressed, absorbing impact energy and forming an elastic buffer interval; one end of the outer cylinder 401 is fixedly connected with the connecting plate 33, and the other end is movably connected with the inner side wall of the box body 1, ensuring that the outer cylinder 401 is stretched out of the box body 1 under the driving of the connecting plate 33, and ensuring the stability of unfolding and folding through the movable connection with the inner side wall of the box body 1; the contact outer ring 402 is connected with the outer side wall of the outer cylinder 401, so that the contact outer ring 402 moves synchronously with the outer cylinder 401, and the force is transmitted to the outer cylinder 401 through the contact surface when the contact impact occurs to start the subsequent buffer coordination; the honeycomb groove 404 is distributed circumferentially along the inner core 403, ensuring that the inner core 403 can deform and disperse force through the honeycomb groove 404 when impacted in all directions, realizing omnidirectional energy dispersion; the corrugated spring layer 405 is a continuous wave shape structure, and the deformation stroke is increased by wave shape design to improve the energy absorption efficiency, and the continuous structure ensures uniform stress and avoids local fracture; the corrugated spring layer 405 is arranged in an axial stacking manner along the inner core 403, increasing the overall length and elastic deformation space in the axial direction, so that the impact energy is gradually absorbed in a longer axial stroke; and the two ends are respectively abutted with the inner wall of the outer cylinder 401 and the outer wall of the inner core 403, ensuring that the spring layer is simultaneously pressed from both sides when the inner and outer cylinders 401 move relatively, fully deforming to absorb energy and realizing the elastic buffering function.

[0016] Working principle: In the initial state, the portable anti-collision shock-resistant field nursing box is kept closed by the box lock 2, and the whole is in a stable state ready for use. At this time, the trigger plate 31 of the trigger mechanism 3 is attached to the outer side wall of the box 1 through the sliding fit structure, the circular hole 312 on the surface of the trigger plate 31 is not aligned with the top column 322 of the reaction piece 32, the ejection spring 323 of the reaction piece 32 is in a compressed state, and the top column 322 is blocked by the trigger plate 31 and cannot move outward. The buffer mechanism 4 is retracted and accommodated in the inner side wall of the box 1, the outer cylinder 401 and the inner core 403 remain relatively stationary, the contact outer ring 402 is attached to the outer side wall of the outer cylinder 401, and the corrugated spring layer 405 and the honeycomb groove 404 are in a natural unstressed state. The load-bearing foam board 7 inside the box 1 and the breathable foam cover 5 cover each other, the articles are stably stored through the clamping groove 8 on the top of the two, and the breathable hole 6 on the surface of the breathable foam cover 5 remains unobstructed.

[0017] When the box 1 is subjected to external collision or impact, the external force first acts on the trigger plate 31 around the box 1, and the trigger plate 31 is displaced inward along the lateral direction of the box 1. In this process, the extrusion strip 313 on the edge of the trigger plate 31 moves synchronously with the smooth plate body 311, thereby extruding the breathable foam cover 5 and the load-bearing foam board 7 inside the box 1, so as to enhance the fixing ability of the breathable foam cover 5 and the load-bearing foam board 7 to the stored articles. With the continuous displacement of the trigger plate 31, the circular hole 312 formed on the surface of the trigger plate 31 is axially aligned with the top column 322 in the double-headed sleeve 321 of the reaction piece 32, thereby providing a path for the movement of the top column 322.

[0018] After the circular hole 312 is aligned with the top column 322, the ejection spring 323 in the compressed state in the reaction piece 32 begins to release the elastic potential energy, and under the action of the elastic force, the top column 322 is pushed to move outward along the axial direction of the double-headed sleeve 321. After the front end of the top column 322 penetrates through the circular hole 312, it continues to protrude outward, and the end thereof transmits the pushing force to the buffer mechanism 4 through the contact with the connecting plate 33, thereby driving the buffer mechanism 4 to switch from the retracted state to the expanded state, and at the same time, the buffer distance of the buffer mechanism 4 is lengthened, so as to improve the buffering effect.

[0019] Under the driving of the connecting plate 33, the outer cylinder 401 of the buffer mechanism 4 extends outward along the inner side wall of the box 1 and protrudes outside the box 1, and the contact outer ring 402 on the outer side of the outer cylinder 401 moves synchronously with the outer cylinder 401, and gradually aligns with the objects that may be contacted with the outside. During the movement of the outer cylinder 401, the inner core 403 embedded therein changes its position relative to the outer cylinder 401, the distance between the honeycomb groove 404 on the outer surface of the inner core 403 and the inner wall of the outer cylinder 401 gradually decreases, and the corrugated spring layer 405 filled therebetween begins to be extruded, and the continuous wave-shaped structure is gradually deformed and stored.

[0020] When the buffer mechanism 4 is fully deployed, one end of the outer cylinder 401 is connected to the reaction member 32 through the connecting plate 33, and the other end extends outside the box body 1 to form a protective extension structure. The contact outer ring 402 is fully attached to the outer sidewall of the outer cylinder 401 and exposed outside the box body 1, becoming the first component to contact external impact. The corrugated spring layer 405 forms an elastic buffer interval under continuous compression, and the honeycomb groove 404 of the inner core 403 further disperses the impact force that may be received through its own structural deformation, together constituting a multiple buffer protection system.

[0021] If it is necessary to access the items stored inside the box body 1, the box lock 2 can be operated to release the closed state of the box body 1, and the cover structure of the box body 1 is opened. At this time, the breathable foam cover 5 covering the top of the carrying foam plate 7 can be detached and separated, and the carrying foam plate 7 and the clamping groove 8 on the top of the breathable foam cover 5 are fully exposed. The rescue tools, medicines and other items stored in the clamping groove 8 can be directly taken out and used. The air-permeable holes 6 on the surface of the breathable foam cover 5 maintain air circulation during the opening of the box body 1, avoiding the dampness or mildew of the internal items due to the closed environment.

[0022] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application should be included in the protection scope of the present application.
