Description

Technical Field

[0001] The invention relates to the technical field of rescue boxes, in particular to a medical rescue box used in battlefields in high-cold areas. Background Art

[0002] The medical rescue kit for high-altitude battlefields is designed to deal with injuries and illnesses of combatants in extremely cold environments. Its main purpose is to provide basic supplies required for emergency medical rescue. The climate in these areas is harsh, the temperature is extremely low, and medical rescue faces many challenges. Therefore, the first aid kit in high-altitude battlefields needs to be designed according to the special requirements of the extremely cold environment to ensure that it can still be used effectively in low temperatures.

[0003] After searching, the Chinese patent with publication number CN115429546B includes a box, a shoulder strap is installed on the outside of the box, and at least one group of partitions is installed inside the box, and a self-locking buckle is installed between the two ends of the shoulder strap; the inner wall of the box is provided with a heat-conducting member, and a heat-averaging layer is provided on the outer side of the inner wall of the box near the heat-conducting member, and multiple active heating members are installed on the side of the partition and the box near the heat-conducting member, and multiple emergency heating components are installed on the side of the box near the active heating member. The above patent is provided with two groups of heating structures, active heating members and emergency heating components. In daily use, the storage area inside the box can be kept at a constant temperature by the active heating members. After the energy is consumed, the storage area in the box can be kept above a suitable temperature for a certain period of time by the emergency heating components.

[0004] However, the heating function of the emergency heating component in the above patent is achieved through the heat release of the chemical reaction of quicklime and water to generate calcium hydroxide.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figures 1 to 9 The present invention provides a technical solution: a medical rescue box for battlefields in high-cold areas, comprising a control component arranged at the middle of the top of an outer box body 1, a storage component connected to the control component in a transmission manner, and an electric control system for controlling the heating and heat preservation of the rescue box, wherein a heat preservation layer 11 is fixedly connected to the inside of the outer box body 1, and an aluminum foil layer 12 is coated on the outer peripheral surface of the heat preservation layer 11, and two symmetrical cover plates 13 are arranged on the top of the outer box body 1, and a vacuum layer 14 is arranged between the outer box body 1 and the heat preservation layer 11, and a card slot 15 is opened on the opposite surfaces of the two cover plates 13;

[0037] The control assembly includes a handle 2 for people to pull to transport the rescue box and a lifting mechanism for controlling the height of the storage assembly, and the lifting mechanism is arranged on the inner wall of the insulation layer 11;

[0038] The storage assembly includes a storage layer 41 for storing medicines and a clamping mechanism for improving the grip strength of the rescue box. The clamping mechanism is arranged on the inner contour around the outer box body 1.

[0039] In the present device, the outer box body 1 serves as the shell structure of the rescue box to realize the protection function of the internal medicines. The personnel realize the transportation operation of the rescue box by pulling the control component and realize the automatic response of the rescue box by pressing the control component. During the automatic response of the rescue box, the storage component automatically rises and expands to both sides, thereby exposing the medicines stored inside to the external environment and allowing them to be freely taken. At the same time, after the rescue operation is completed, the personnel can pull the control component to realize the transportation of the rescue box, and the rescue box and the storage component can be retracted and reset without additional operation, thereby greatly improving the response speed of the rescue box.

[0040] The insulation layer 11 serves as the insulation structure of the rescue box, and realizes the heating and constant temperature function of the medicines stored in the storage component through cooperation with the electronic control system. The aluminum foil layer 12 is used to reflect the heat radiation inside the insulation layer 11, thereby reducing the heat energy loss inside the insulation layer 11 to improve the heating and constant temperature efficiency of the rescue box. The cover 13 cooperates with the control component to realize automatic expansion when people pull it up, and at the same time isolates the inside and outside of the outer box body 1 when the cover 13 is closed. The vacuum layer 14 further isolates the temperature difference between the inside and outside of the insulation layer 11, and further maintains the effective duration of the heating function of the rescue box by reducing the heat energy loss caused by heat convection inside the insulation layer 11.

[0041] Embodiment 2:

[0042] See also Figure 4-Figure 5 This embodiment further illustrates the following on the basis of the first embodiment:

[0043] The bottom ends of the handle 2 on both axial sides are fixedly connected with fixing rods 21, and the fixing rods 21 are slidably connected to the inner contour of the slot 15. The fixing rods 21 are fixedly connected with racks 22 on both sides located inside the outer box body 1. A transmission wheel 23 is meshed and transmission-connected on the outer contour of the top of the rack 22. A positioning shaft 24 is penetrated and fixedly connected at the axis of the transmission wheel 23. The positioning shaft 24 penetrates and is rotatably connected to the inner contour of the thermal insulation layer 11. A chain 25 is meshed and transmission-connected on the outer contour of the positioning shaft 24. The chain 25 is embedded in the peripheral wall of the thermal insulation layer 11, and a cavity for the chain 25 to rotate is opened at a corresponding position of the inner wall of the thermal insulation layer 11. A positioning shaft 27 is meshed and transmission-connected on the inner contour of the other end of the chain 25. The positioning shaft 27 penetrates and is rotationally connected to the inner contour of the thermal insulation layer 11, and a transmission wheel 26 is penetrated and fixedly connected on the outer contour of the positioning shaft 27.

[0044] The lifting mechanism includes a transmission shaft 31 that passes through and is limitedly rotatably connected to both sides of the top of the insulation layer 11, and transmission wheels 3 3 are passed through and fixedly connected at both ends of the transmission shaft 31. The transmission wheels 3 3 are respectively meshed with and transmission-connected to the positioning shafts 2 27 at corresponding positions, and differentials 32 are arranged on both sides of the transmission shaft 31 near the middle section, and a positioning wheel 33 is passed through and rotationally connected to the middle section of the transmission shaft 31, and the positioning wheel 33 is transmission-connected to the differential 32.

[0045] The outer contour of the transmission wheel three 3 is fixedly connected to the cover plate 13, the transmission ratio of the transmission wheel three 3 to the transmission wheel two 26 is set to one to one, and the transmission ratio of the transmission wheel three 3 to the positioning wheel 33 is set to one to four.

[0046] It can be seen from Example 1 that personnel can realize the automatic response operation of the rescue box by lifting and pressing down the control component. First, when the rescue box needs to be transported to the designated location, the personnel pulls up the handle 2. At this time, the fixing rod 21 synchronously extends from the inside of the outer box body 1 through the slot 15 and is fixed after reaching the limit position. When the rescue box needs to be unfolded after the transportation is completed, the personnel places the rescue box on the ground and presses down the handle 2. At this time, the fixing rod 21 descends through the slot 15 and retracts back into the inside of the outer box body 1, and the rack 1 22 moves synchronously and drives the transmission wheels 1 23 on both sides thereof to rotate. The transmission wheel 1 23 further drives the positioning shaft 1 24 to rotate, and the positioning shaft 1 24 drives the chain 25, the positioning shaft 2 27 and the transmission wheel 2 26 to rotate synchronously. Here, the positioning shaft 1 24 and the positioning shaft 2 27 are set to the same specifications, and the transmission wheel 1 23 and the transmission wheel 2 26 are set to the same specifications, that is, the transmission ratio between the transmission wheel 1 23 and the transmission wheel 2 26 is fixed to one to one.

[0047] Furthermore, the gear ratio between the transmission wheel 1 23 and the rack 1 22 is set to 2:1, that is, in the maximum stroke of the rack 1 22 accompanying a single lifting of the fixing rod 21, it drives the transmission wheel 1 23 to rotate half a circle, and the transmission wheel 2 26 rotates 180 degrees synchronously; at this time, the transmission wheel 2 26 further drives the transmission wheel 3 3 and the transmission shaft 31 to rotate, and the transmission shaft 31 drives the differential 32 to start working under the action of its self-rotation, and the differential 32 further drives the positioning wheel 33 to start rotating.

[0048] It should be noted that since the transmission ratio between transmission wheel three 3 and transmission wheel two 26 is one to one, that is, the maximum rotation angle of transmission wheel three 3 and transmission shaft 31 is also one hundred and eighty degrees, at this time, because the cover plate 13 and transmission wheel three 3 are fixedly connected, that is, accompanied by the downward pressure of rack one 22 driven by the fixing rod 21, the transmission wheel three 3 gradually rotates and drives the cover plate 13 to open to release the closed state of the cover plate 13 to the inside of the outer box body 1, and the opening process of the box body is realized at this time.

[0049] Embodiment three:

[0050] See also Figure 6-Figure 7 This embodiment further illustrates the following based on the second embodiment:

[0051] The two storage layers 42 are placed on both sides of the top of the storage layer 1 41, and the tops of the two storage layers 42 are both placed with storage layers 3 43. The middle sections of the two sides of the storage layer 1 41, the storage layer 2 42 and the storage layer 3 43 are penetrated and fixedly connected with the rack 2 4, and the rack 2 4 is meshed and transmission-connected with the differential 32. The middle part of the outer contour of the storage layer 1 41 is rotatably connected with the lifting wheel 44 through the pin shaft, and the outer contour of the lifting wheel 44 is fixed. A lever 45 is connected which extends obliquely outward, and the other end of the lever 45 is rotatably connected to the side of the storage layer 42 close to the opposite surface via a pin shaft. A lever 46 is rotatably connected to the side of the outer contour of the storage layer 41 close to the rack 4 via a pin shaft, and the other end of the lever 46 is rotatably connected to the side of the lever 45 close to the opposite surface via a pin shaft. The middle section of the lever 46 is rotatably connected to the middle section of the outer contour of the storage layer 42 via a pin shaft.

[0052] The transmission ratio between the rack 2 4 and the positioning wheel 33 is one to one, the transmission ratio between the lifting wheel 44 and the transmission wheel 2 26 is set to one to one, and the initial inclination angles of the shifting rod 1 45 and the shifting rod 2 46 are both set to forty-five degrees.

[0053] It can be seen from the first and second embodiments that when the personnel presses down the handle 2, the cover plate 13 opens to realize the opening process of the rescue box, and the lifting assembly automatically rises and unfolds. When the positioning wheel 33 rotates, it drives the rack 2 4 to move synchronously. At this time, under the action of the rack 2 4, the storage layer 1 41, the storage layer 2 42 and the storage layer 3 43 gradually rise and stop when the storage layer 1 41 reaches the highest point. Since the transmission ratio between the rack 2 4 and the positioning wheel 33 is one to one, and the transmission ratio between the positioning wheel 33 and the transmission wheel 3 3 is four to one, the maximum rotation angle of the transmission wheel 3 3 is one hundred and eighty degrees, that is, the maximum rotation angle of the positioning wheel 33 is one hundred and eighty degrees. The movable angle is 720 degrees, that is, the positioning wheel 33 cannot move further after rotating two circles; and when the storage layer 41 rises to the highest point, the positioning wheel 33 rotates exactly one circle, and correspondingly, the transmission wheel 33, the transmission wheel 26 and the transmission wheel 1 23 rotate ninety degrees. At this time, the descending stroke of the fixed rod 21 is just halfway, and then the contact between the positioning wheel 33 and the rack 2 4 is disengaged. The positioning wheel 33 is now located in the gap between the bottom end of the rack 2 4 and the storage layer 1 41, thereby realizing the positioning work of the storage layer 1 41 after it rises to the highest point, avoiding movement interference in the subsequent unfolding process due to over-extension of the storage layer 1 41.

[0054] After the storage layer 1 41 rises to the highest point, since the fixing rod 21 has descended more than half of its stroke, that is, the fixing rod 21 continues to descend along with the handle 2, the transmission wheel 3 3 continues to rotate, and the cover 13 further tilts from the vertical state to release the obstruction to the storage assembly to ensure the subsequent smooth unfolding of the storage assembly.

[0055] When the storage layer 1 41 rises to the highest point, the lifting wheel 44 rises synchronously and meshes with the transmission wheel 2 26 when the storage layer 1 41 reaches the highest point. Since the transmission ratio between the lifting wheel 44 and the transmission wheel 2 26 is one to one, and the rotation stroke of the transmission wheel 2 26 is more than half at this time, that is, the lifting wheel 44 can continue to rotate with the transmission wheel 2 26 for at most ninety degrees, and the maximum rotation angle of the lifting wheel 44 is ninety degrees.

[0056] Subsequently, the transmission wheel 26 drives the lifting wheel 44 to rotate synchronously, and the lifting wheel 44 drives the lever 1 45 to deflect synchronously, and the lever 1 45 further pulls the storage layer 2 42 to expand outward. At this time, during the outward expansion of the storage layer 2 42, it drives the lever 2 46 to move synchronously, and the position of the storage layer 1 41 is fixed, that is, when the lever 2 46 accompanies the outward expansion of the storage layer 2 42, the position of the bottom end of the lever 2 46 remains unchanged, which causes the lever 2 46 to deflect synchronously and the deflection angle is the same as that of the lever 1 45; further, the deflection of the lever 2 46 pulls the storage layer 3 43 to expand outward, thereby realizing the multi-stage expansion operation between the storage layer 1 41, the storage layer 2 42 and the storage layer 3 43, and the maximum rotation angle of the lever 1 45 and the lever 2 46 is ninety degrees.

[0057] Embodiment 4:

[0058] See also Figure 8 This embodiment further illustrates the following on the basis of the third embodiment:

[0059] The locking mechanism includes a connecting rope 5 fixedly wound on the outer contours of both ends of the transmission shaft 31, the connecting rope 5 passes through and is slidably embedded in the surrounding walls of the four corners of the outer box body 1, the bottom end of the connecting rope 5 is fixedly connected with a grab hook 51, and a positioning pin 52 is passed through and rotatably connected to the position of the grab hook 51 near the connecting rope 5, the positioning pin 52 passes through and is fixedly connected to the inner wall of the outer box body 1, and a tension spring 53 is fixedly connected between the upper surface of the grab hook 51 and the inner wall of the outer box body 1.

[0060] It can be seen from Example 1 that when a person presses down the handle 2 to unfold the rescue box, the locking mechanism synchronizes the process and improves the grip of the rescue box, thereby ensuring that the rescue box does not slip when the ground is frozen and the friction is low. During this process, the rack 22 descends and drives the transmission wheel 23 to rotate. The transmission wheel 23 further drives the transmission shaft 31 to rotate through motion transmission. At this time, the rotation of the transmission shaft 31 causes the connecting rope 5 to gradually reel in, and the effective length of the connecting rope 5 is shortened, resulting in a gradual increase in the pulling force of its bottom end on the grab hook 51; further, the grab hook 51 is affected by the pulling force of the connecting rope 5 and begins to deflect along the positioning pin 52, causing the tension spring 53 to deform and the elastic potential energy to increase. Since the grab hook 51 is initially in a horizontal state extending outward, when the rescue box is placed on the ground, the tip of the grab hook 51 just inserts into the ground. Subsequently, during the deflection of the grab hook 51 along the positioning pin 52, the degree to which the tip of the grab hook 51 inserts into the ground is further increased, thereby effectively improving the grip of the rescue box to prevent the rescue box from slipping.

[0061] Furthermore, the increase in the elastic potential energy of the tension spring 53 can effectively ensure the rapid resetting of the grab hook 51 during the subsequent contraction and folding process, and the resetting of the grab hook 51 can reduce the degree of insertion and engagement with the ground, thereby releasing the gripping and fixing effect on the outer box body 1.

[0062] It should be noted that a buckle is provided between the bottom end of the fixing rod 21 and the inner wall of the insulation layer 11, and when the fixing rod 21 is lowered to the limit position along with the handle 2, the buckle is automatically engaged, and at this time the height position of the fixing rod 21 is fixed, so that the personnel can stop holding the handle 2 and automatically take out the medicines stored in the storage layer 1 41, the storage layer 2 42 and the storage layer 3 43; then when the rescue box needs to be retracted and closed, the personnel pulls the handle 2 upwards, and at this time the outer box body 1 tends to remain fixed due to the insertion and engagement between the grab hook 51 and the ground, so that the process of the personnel pulling the handle 2 will release the engagement state of the buckle between the bottom end of the fixing rod 21 and the insulation layer 11, and further, the personnel continue to pull the handle 2, and the rescue box realizes the retraction and folding operation.

[0063] Embodiment five:

[0064] See also Fig. 9 This embodiment further illustrates the following on the basis of the fourth embodiment:

[0065] The electric control system includes a solar panel arranged on the upper surface of the cover plate 13, a height sensor arranged at the bottom end of the storage layer 141, a temperature sensor arranged on the inner wall of the insulation layer 11, and an electric heating belt embedded and fixedly connected to the peripheral wall of the insulation layer 11;

[0066] The height sensor is configured to monitor the distance between the bottom end of the storage layer 41 and the inner wall of the insulation layer 11 and send a start / stop signal to the electric heating belt when it is at the limit position;

[0067] The temperature sensor is configured to monitor the temperature inside the insulation layer 11 and control the power of the electric heating tape;

[0068] The solar panel is configured to be connected to the electric heating tape through an electric circuit and transmit electrical energy to the electric heating tape;

[0069] The electric heating tape is configured to heat the interior of the insulation layer 11 according to the received signal.

[0070] First, the corresponding temperature range is set according to the medicines stored in the storage layer 1 41, the storage layer 2 42 and the storage layer 3 43. When the distance between the bottom end of the storage layer 1 41 and the inner wall of the insulation layer 11 reaches the minimum value, that is, the rescue box is in a retracted and closed state, the height sensor sends an open signal to the electric heating tape. At this time, the electric heating tape heats the inside of the insulation layer 11 and stops working after the temperature rises to the set range.

[0071] Subsequently, the heat energy inside the insulation layer 11 can effectively reduce the escape rate under the shielding effect of the aluminum foil layer 12 and the vacuum layer 14, thereby increasing the insulation time. When the temperature sensor detects that the temperature inside the insulation layer 11 drops and exceeds the set range, the electric heating tape works again to raise the temperature again, thereby realizing the constant temperature storage function of the medicines.

[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
