The box body can hold medicines, first aid tools, etc. When performing first aid operations, it is first necessary to open the cover body, take out the first aid tools, and then disinfect the first aid tools before using them. The operation is cumbersome and not conducive to improving first aid efficiency. In addition, when performing first aid operations, sufficient operating space is often required to place and use first aid tools. However, traditional first aid kits often cannot provide sufficient operating table space, which limits the operating efficiency of first aid personnel. In order to solve the above problems, the present invention proposes a first aid box for storing first aid tools. Summary of the Invention

[0016] 2. In the first state, when the second and third boxes are both located on the upper surface of the first box, they have the advantage of occupying a small area, making them convenient for storage or transportation. At the same time, their small horizontal length makes them easy to carry and move, avoiding collisions with other people or objects during movement, which could cause injury. In the third state, the upper surfaces of the first, second, and third boxes form an operating table, providing a large operating space for emergency operations.

[0017] 3. Pull the first limit plate to fix the instrument placement module horizontally in the limit channel to facilitate taking the instrument.

[0018] 4. The setting of the bending guide groove and the rectangular sliding frame slows down the falling speed of the second box body, thereby preventing the second box body and the third box body from being damaged by excessive impact force when they come into contact with the fixed support plate due to excessive falling speed.

[0021] 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.

[0022] like Figure 1-Figure 23 As shown, the technical solution adopted by the present invention is as follows: a first aid box for storing first aid tools comprises a first box body 1, a second box body 2 and a third box body 3. Figure 1 As shown, C-shaped rods 6 are slidably connected to the front and rear sides of the first housing 1. Specifically, limit slots 4 are provided on both sides of the first housing 1. A slider 5 is fixedly connected to the middle of the C-shaped rod 6, and the slider 5 is slidably positioned within the limit slot 4 on the same side. A sliding rod 7 is fixedly connected between the two ends of each C-shaped rod 6, and a fixed stop 701 is fixedly connected to the middle of each sliding rod 7. A first slide 8 and a second slide 9 are slidably mounted on each sliding rod 7, with the first slide 8 and the second slide 9 being located on either side of the fixed stop 701. The first slide 8 is fixedly connected to the second housing 2, and the second slide 9 is fixedly connected to the third housing 3. Initially, the second and third housings 2 and 3 are both located on the upper end surface of the first housing 1, and the second and third housings 3 are arranged side by side. The first and second slides 8 and 9 are slid away from the fixed stop 701, gradually moving the second and third housings 2 and 3 apart. When the first slide 8 and the second slide 9 are respectively at the two end ends of the slide rod 7, the lower end surface of the second box body 2 is separated from the upper end surface of the first box body 1, and the lower end surface of the third box body 3 is separated from the upper end surface of the first box body 1, and then the second box body 2 and the third box body 3 fall under the action of gravity, and the C-shaped rod 6 moves downward along the limiting slide groove 4 until the C-shaped rod 6 is at the lower end of the limiting slide groove 4. At this time, the upper end surfaces of the first box body 1, the second box body 2 and the third box body 3 are on the same horizontal plane, and the upper end surfaces of the first box body 1, the second box body 2 and the third box body 3 form an operating table.

[0023] The lower parts of the left and right sides of the first box body 1 are fixedly connected with fixed supporting plates 61. The second box body 2 and the third box body 3 fall onto the corresponding fixed supporting plates 61.

[0024] A disinfection chamber 10 is provided in the second box body 2. A through groove 11 communicating with the disinfection chamber 10 is provided on the upper end surface of the second box body 2. An instrument placement module is provided in the disinfection chamber 10. The instrument placement module includes a plurality of mounting frames 14, and the plurality of mounting frames 14 are connected end to end in sequence, and adjacent mounting frames 14 are rotatably connected to each other. The upper end of the instrument placement module is rotatably connected to an iron connecting plate 13, and the end of the iron connecting plate 13 facing away from the instrument placement module is rotatably connected to a first limit plate 12. The first limit plate 12 is slidably set in the through groove 11, and a handle 22 is fixedly connected to the first limit plate 12. The lower end of the instrument placement module is rotatably connected to a second limit plate 15, and the end of the second limit plate 15 facing away from the instrument placement module is rotatably connected to a shielding plate 16.

[0025] The upper end surface of the third housing 3 is provided with a limiting groove 58. When the third housing 3 and the second housing 2 are arranged side by side on the upper end surface of the first housing 1, the through slot 11 and the limiting groove 58 are in communication.

[0026] A limiting assembly is provided on the first limiting plate 12, and the limiting assembly includes a limiting pin 24. The handle 22 is slidably connected to a slide plate 23, and a first spring 25 is fixedly connected between the slide plate 23 and the upper end of the handle 22. The lower end of the slide plate 23 is fixedly connected to the upper end of the limiting pin 24. The first limiting plate 12 is provided with a through hole that slidably cooperates with the limiting pin 24. The lower end of the limiting pin 24 extends through the through hole to the bottom of the first limiting plate 12. The lower end of the limiting pin 24 is provided with an inclined surface. When the handle 22 moves toward the limiting groove 58, the inclined surface allows the limiting pin 24 to contact the side wall of the disinfection chamber 10, allowing the limiting pin 24 to move upward and enter the through groove 11. The bottom wall of the limiting groove 58 is provided with a pin slot 59 that cooperates with the limiting pin 24. The lower end of the limit pin 24 is inserted into the pin slot 59, thereby connecting the second box body 2 and the third box body 3 together. At this time, under the limitation of the fixed block 701, the second box body 2 cannot move toward the direction close to the third box body 3, and the third box body 3 cannot move toward the direction close to the second box body 2. The first box body 1, the second box body 2 and the third box body 3 are in a locked state, which is convenient for transportation, storage and carrying.

[0027] A limiting channel 53 cooperating with the instrument placement module is provided on the upper end surface of the first box body 1. The limiting channel 53 runs through the left and right sides of the first box body 1. When the first box body 1, the second box body 2 and the third box body 3 form an operating table, one end of the limiting channel 53 is connected to the through groove 11, and the other end of the limiting channel 53 is connected to the limiting groove 58. By pulling the first limiting plate 12 in the direction of the limiting groove 58 by the handle 22, the instrument placement module gradually moves out of the disinfection chamber 10 and enters the limiting channel 53 until the limiting pin 24 is stuck in the pin slot 59. It is convenient to take the instruments placed on the instrument placement module. At this time, the second limiting plate 15 and the shielding plate 16 block the connection between the through groove 11 and the disinfection chamber 10, protect the disinfection chamber 10, and prevent impurities from entering the disinfection chamber 10.

[0028] like Figure 8 、 Figure 9 As shown, a fixed splint 17 is fixedly installed at one end of the mounting frame 14. A movable splint 18 is slidably installed above the fixed splint 17 in the mounting frame 14. Tension spring grooves are provided on both sides of the mounting frame 14. The end of the movable splint 18 is slidably set in the tension spring groove on the same side. A tension spring 20 is provided in the tension spring groove, and the tension spring 20 is fixedly connected between the movable splint 18 and the end wall of the tension spring groove. An instrument limiting groove 21 is provided on the side where the fixed splint 17 and the movable splint 18 are close to each other. The instrument limiting groove 21 can be set according to the characteristics of the instrument to be placed, so that one end of the instrument is located in the instrument limiting groove 21. Under the clamping action of the fixed splint 17 and the movable splint 18, the instrument is fixed on the mounting frame 14. For example, Figure 8 The scalpel is shown fixed on the mounting frame 14. Figure 9 The figure shows a pair of scissors secured to the mounting frame 14. The shape of the instrument retaining slot 21 depends on the instrument being secured. This configuration facilitates the clamping of unusually shaped instruments. Only the clamping shapes for scalpels and scissors are illustrated here. Other mounting frames 14 may also have retaining slots 21 for other instruments, but these are not shown.

[0029] A handle 19 is fixedly provided on the movable splint 18. When it is necessary to take an instrument, the handle 19 is used to move the movable splint 18 upward away from the fixed splint 17, thereby releasing the grip on the instrument. When the instrument placement module is in the limiting channel 53, the movable splint 18 is above the fixed splint 17.

[0030] Both sides of the disinfection chamber 10 are provided with nozzle seats 26, on which a plurality of nozzles are provided, and the instrument placement module is located between the two nozzle seats 26. The nozzle seats 26 spray disinfectant and sterile gas to the instrument placement module.

[0031] The second housing 2 is provided with a liquid supply mechanism and an air supply mechanism. The liquid supply mechanism delivers disinfectant to the nozzle seat 26, and the air supply mechanism delivers sterile gas to the nozzle seat 26.

[0032] The liquid supply mechanism is arranged in linkage with the first slide 8 . When the first slide 8 slides along the C-shaped rod 6 away from the fixed stopper 701 , the liquid supply mechanism delivers the disinfectant into the nozzle seat 26 .

[0033] like Figure 2 、 Figure 10 、 Figure 11 、 Figure 17 As shown, the liquid supply mechanism includes a liquid storage tank 27, a liquid piston cylinder 28 and a liquid piston rod 29. One end of the liquid piston cylinder 28 is fixedly connected to the first slide 8, and one end of the liquid piston rod 29 is slidably arranged in the liquid piston cylinder 28. The end of the liquid piston rod 29 that extends into the liquid piston cylinder 28 is in sealed sliding cooperation with the liquid piston cylinder 28. The other end of the liquid piston rod 29 is fixedly connected to the end of the C-shaped rod 6. A first liquid channel 30 connected to the liquid piston cylinder 28 is provided on the side wall of the liquid piston cylinder 28. A first liquid one-way valve 31 is provided at the end of the first liquid channel 30 connected to the liquid piston cylinder 28. The disinfectant in the liquid piston cylinder 28 enters the first liquid channel 30 through the first liquid one-way valve 31. The first slide 8 is provided with a second liquid channel 32 connected to the first liquid channel 30. The second liquid channel 32 extends into the interior of the second housing 2. The second housing 2 is provided with a third liquid channel 33 connected to the second liquid channel 32. Both ends of the third liquid channel 33 are connected to first pipe connectors 34. The two first pipe connectors 34 correspond one-to-one with the two nozzle seats 26, and the first pipe connectors 34 are connected to the corresponding nozzle seats 26. When the first slide 8 slides in a direction away from the fixed block 701, the liquid piston cylinder 28 slides, and the disinfectant in the liquid piston cylinder 28 flows through the first liquid one-way valve 31, the first liquid channel 30, the second liquid channel 32, the third liquid channel 33, the first pipe connector 34, and enters the nozzle seat 26. It is then sprayed toward the instrument placement module through the nozzle, thereby disinfecting the instruments on the instrument placement module.

[0034] The liquid storage tank 27 is disposed within the second housing 2. The first slide 8 defines a fifth liquid channel 37, which extends into the second housing 2 and communicates with the liquid storage tank 27. A fourth liquid channel 35 is defined on the sidewall of the liquid piston cylinder 28. One end of the fourth liquid channel 35 communicates with the liquid piston cylinder 28. A second liquid one-way valve 36 is provided at the connection between the fourth liquid channel 35 and the liquid piston cylinder 28. The other end of the fourth liquid channel 35 communicates with the fifth liquid channel 37. When the first slide 8 moves toward the fixed stop 701, the liquid piston cylinder 28 moves toward the liquid piston rod 29. The disinfectant in the liquid storage tank 27 enters the liquid piston cylinder 28 through the fifth liquid channel 37, the fourth liquid channel 35, and the second liquid one-way valve 36, replenishing the liquid piston cylinder 28 with disinfectant.

[0035] A drainage channel 63 is provided at the bottom of the disinfection chamber 10 , and the disinfectant entering the disinfection chamber 10 is discharged through the drainage channel 63 .

[0036] A sliding cavity 38 is provided in the second box body 2, and a rectangular sliding frame 39 is elastically slidably provided in the sliding cavity 38, and the rectangular sliding frame 39 slides close to or away from the instrument placement module. A second spring 43 is fixedly connected between the rectangular sliding frame 39 and the side wall of the sliding cavity 38. Initially, under the action of the second spring 43, the rectangular sliding frame 39 is in the middle of the sliding cavity 38. A magnet 40 is fixedly connected to the upper side of the rectangular sliding frame 39, and the magnet 40 is arranged in conjunction with the iron connecting plate 13. The magnet 40 adsorbs the iron connecting plate 13, and the instrument placement module is in a vertical state and is located in the disinfection cavity 10.

[0037] like Figure 4 As shown, a connecting rod 41 is fixedly connected to the lower end of the rectangular sliding frame 39, near the instrument placement module. The connecting rod 41 extends through the second housing 2 and extends outside the second housing 2. A guide rod 42 is fixedly connected to the end of the connecting rod 41 located outside the second housing 2. A clearance groove 60 is defined on the third housing 3 at a position corresponding to the connecting rod 41. When the second housing 2 and the third housing 3 are placed side by side on the upper end surface of the first housing 1, the connecting rod 41 extends into the clearance groove 60, thereby causing the second housing 2 and the third housing 3 to contact each other.

[0038] like Figure 1 、 Figure 15 、 Figure 16As shown, a vertical groove 54 is formed on the left side of the first housing 1. The upper end of the groove 54 communicates with the limiting passage 53. A wavy curved guide groove 55 is formed on both the front and rear sides of the groove 54. The curved guide groove 55 mates with the guide rod 42 and slides with it. A vertical guide groove 56 is formed on the right side of the groove 54. The upper ends of the curved guide groove 55 and the vertical guide groove 56 communicate with the limiting passage 53, while the lower ends of the curved guide groove 55 communicate with the lower end of the vertical guide groove 56. A baffle 57 is elastically rotatably provided on the lower end of the vertical guide groove 56, near the curved guide groove 55. The upper end of the baffle 57 is rotatably connected to the first housing 1 via a rotating rod. The rotating rod is equipped with a torsion spring, which is fixedly connected between the baffle 57 and the first housing 1. The torsion spring acts to block the curved guide groove 55.

[0039] The bending guide groove 55 and the vertical guide groove 56 are both slidably matched with the guide rod 42. When the second box body 2 falls, the guide rod 42 slides downward in the bending guide groove 55. Under the guiding action of the bending guide groove 55, the guide rod 42 moves back and forth left and right. The guide rod 42 drives the rectangular sliding frame 39 to move back and forth left and right through the connecting rod 41. The rectangular sliding frame 39 drives the iron connecting plate 13 to move back and forth left and right. The instrument placement module swings left and right, and the instrument placement module is wavy in the process of swinging left and right. The disinfectant on the instrument is thrown off by the instrument placement module during the swinging process, which is conducive to accelerating the drying of the instrument.

[0040] When the first slide 8 moves downward, the air supply mechanism delivers sterile gas into the nozzle seat 26 to dry the disinfectant on the instrument placement module.

[0041] like Figure 12 、 Figure 13 、 Figure 14As shown, the gas supply mechanism includes a sterile air bag and a gas piston rod 45. Two gas piston cylinders 44 are disposed within the second housing 2, one on each side of a rectangular slide frame 39. A gas piston rod 45 is slidably disposed within each gas piston cylinder 44. The end of the gas piston rod 45 located within the gas piston cylinder 44 is in sealed sliding contact with the gas piston rod 45, while the end of the gas piston rod 45 extending outside the gas piston cylinder 44 is fixedly connected to the rectangular slide frame 39. A second gas channel 48, a third gas channel 50, and a fourth gas channel 51 are defined within the second housing 2. Both ends of the second gas channel 48 are connected to the two gas piston cylinders 44 respectively. A second gas one-way valve 49 is provided at the end of the second gas channel 48. The gas in the gas piston cylinder 44 flows out through the second gas one-way valve 49. The third gas channel 50 connects the second gas channel 48 and the fourth gas channel 51. Both ends of the fourth gas channel 51 are connected to a second pipe connector 52. The two second pipe connectors 52 correspond one-to-one to the two nozzle seats 26, and the second pipe connectors 52 are connected to the corresponding nozzle seats 26.

[0042] The second housing 2 is provided with a first gas passage 46 connected to the gas piston cylinder 44. Both first gas passages 46 are connected to the sterile air bag. A first gas check valve 47 is provided at the end of the first gas passage 46 near the gas piston cylinder 44, allowing gas to flow into the gas piston cylinder 44. The sterile air bag can be placed on one side of the second housing 2.

[0043] like Figure 12 As shown, when the rectangular slide 39 moves leftward, the sterile gas in the left gas piston cylinder 44 flows sequentially through the second gas check valve 49, the second gas channel 48, the third gas channel 50, and the fourth gas channel 51 into the nozzle holder 26. The nozzle holder 26 sprays the sterile gas toward the instrument placement module, drying the instruments. Simultaneously, the sterile gas in the sterile air bag flows through the first gas channel 46 and the first gas check valve 47 into the right gas piston cylinder 44. Similarly, when the rectangular slide 39 moves rightward, the sterile gas in the sterile air bag flows into the left gas piston cylinder 44. The gas in the right gas piston cylinder 44 flows sequentially through the second gas check valve 49, the second gas channel 48, the third gas channel 50, and the fourth gas channel 51 into the nozzle holder 26. The nozzle holder 26 sprays the sterile gas toward the instrument placement module, drying the instruments. As the rectangular slide 39 reciprocates left and right, sterile gas is continuously blown toward the instruments, accelerating their drying.

[0044] The second box body 2 and the third box body 3 are both rotatably connected to the side away from each other with a handle 62, so that the first aid kit is easy to carry.

[0045] Working principle: like Figures 1-16As shown, the first aid kit is in a first state, i.e., an initial state. In the initial state, the second box body 2 and the third box body 3 are arranged side by side on the upper end surface of the first box body 1, and the end of the connecting rod 41 is located in the clearance groove 60. The first slide 8 and the second slide 9 are both in contact with the fixed block 701. The iron connecting plate 13 is in a vertical state, and the iron connecting plate 13 is limited by the first limiting plate 12 and cannot rotate counterclockwise. The magnet 40 adsorbs the iron connecting plate 13, and the limiting pin 24 extends into the disinfection chamber 10. At this time, the iron connecting plate 13, multiple mounting frames 14, the second limiting plate 15, and the shielding plate 16 are in a vertical state under the action of gravity. Under the action of the second spring 43, the rectangular sliding frame 39 is in the middle of the sliding chamber 38.

[0046] When you need to carry, transport or store the device, Figure 4 As shown, when the handle 22 is pulled to the right, it drives the first stop plate 12 to the right, separating the iron connecting plate 13 from the magnet 40. As the first stop plate 12 moves rightward, the stop pin 24, acting on the inclined surface at its bottom, slides upward. The first stop plate 12 gradually inserts into the stop groove 58, eventually resting its right end against the end of the stop groove 58. At this point, the iron connecting plate 13 enters the through groove 11 and assumes a horizontal position. At this point, the first stop plate 12 and the iron connecting plate 13 precisely block the gap connecting the upper end of the disinfection chamber 10 to the through groove 11, preventing impurities from falling into the disinfection chamber 10. Furthermore, the stop pin 24 has just moved above the latch slot 59. Under the action of the first spring 25, the stop pin 24 is inserted downward into the latch slot 59. At this point, the first stop plate 12 cannot move any further, effectively connecting the second and third chambers 2 and 3. The first, second, and third housings 1, 2, and 3 are locked together. The first aid kit now takes up a vertical position, taking up a small footprint and facilitating storage or transportation. Its small horizontal length also makes it easy to carry and move, preventing it from bumping into other people or objects and causing injury. When carrying it, the two handles 62 can be rotated upward for easier portability.

[0047] When in use, pull the slide plate 23 upward, the limit pin 24 moves upward and disengages from the pin slot 59, and the handle 22 is pulled toward the second box body 2. The first limit plate 12 and the iron connecting plate 13 move toward the second box body 2, and the iron connecting plate 13 enters the disinfection chamber 10. Under the action of gravity, the iron connecting plate 13 rotates downward to a vertical state, so that the first limit plate 12 and the iron connecting plate 13 continue to move until the iron connecting plate 13 is adsorbed on the magnet 40, the first limit plate 12 returns to the initial position, and the handle 22 stops moving.

[0048] like Figure 1The second box body 2 and the third box body 3 are then pushed to the sides respectively. The second box body 2 slides to the left along the slide rod 7 through the first slide seat 8, and the third box body 3 slides to the right along the slide rod 7 through the second slide seat 9.

[0049] At the same time, the first slide 8 drives the liquid piston cylinder 28 to move, and the liquid piston cylinder 28 moves relative to the liquid piston rod 29. In this way, the disinfectant in the liquid piston cylinder 28 sequentially passes through the first liquid one-way valve 31, the first liquid channel 30, the second liquid channel 32, the third liquid channel 33, and the first pipe joint 34 to enter the nozzle seat 26. The nozzle of the nozzle seat 26 is sprayed toward the installation frame 14, thereby disinfecting and cleaning the instruments in the installation frame 14. The disinfectant that enters the disinfection chamber 10 is discharged through the drain channel 63. One nozzle seat 26 sprays the disinfectant toward the front of the instrument placement module, and the other nozzle seat 26 sprays the disinfectant toward the back of the instrument placement module, which helps to fully and comprehensively disinfect and clean the instruments.

[0050] The first slide 8 and the second slide 9 move to the two ends of the C-shaped rod 6 respectively, the second box 2 and the third box 3 cannot move outward any further, and the nozzle seat 26 stops spraying the disinfectant. Figure 17 As shown, the first aid kit is in the second state. The guide rod 42 is located directly above the upper entrance of the bending guide groove 55, and the lower end surfaces of the second box body 2 and the third box body 3 are separated from the upper end surface of the second box body 2.

[0051] Afterwards, the second box body 2 and the third box body 3 fall downward under their own gravity, and the C-shaped rod 6 moves downward along the limiting slide groove 4. The guide rod 42 enters the bending guide groove 55 and slides downward along the bending guide groove 55.

[0052] As the second housing 2 moves downward, guided by the curved guide slots 55, the guide rods 42 reciprocate, leading to the connecting rods 41 and the rectangular slide frame 39. The rectangular slide frame 39, through the magnets 40, drives the iron connecting plate 13 to reciprocate, which in turn drives the instrument placement module to swing back and forth in a wave-like pattern. This reciprocating swing of the instrument placement module shakes off disinfectant from the instruments, accelerating the drying process.

[0053] At the same time, during the reciprocating movement of the rectangular sliding frame 39, Figure 12As shown, when the rectangular slide frame 39 moves to the left, the sterile gas in the left gas piston cylinder 44 flows into the nozzle seat 26 through the corresponding second gas check valve 49, second gas channel 48, third gas channel 50, and fourth gas channel 51. The nozzle seat 26 sprays the sterile gas toward the instrument placement module to dry the instruments. One nozzle seat 26 sprays sterile gas toward the front of the instrument placement module, and the other nozzle seat 26 sprays sterile gas toward the back of the instrument placement module, helping to accelerate the drying of the instruments. At the same time, the sterile gas in the sterile air bag enters the right gas piston cylinder 44 through the corresponding first gas channel 46 and first gas check valve 47. Similarly, when the rectangular slide 39 moves rightward, the sterile gas in the sterile air bag flows into the gas piston cylinder 44 on the left. The gas in the right gas piston cylinder 44 then flows through the corresponding second gas check valve 49, second gas channel 48, third gas channel 50, and fourth gas channel 51 into the nozzle holder 26. The nozzle holder 26 sprays the sterile gas toward the instrument placement module, drying the instruments. As the rectangular slide 39 reciprocates left and right, sterile gas continuously flows toward the instruments, helping to accelerate their drying.

[0054] During the reciprocating movement of the rectangular sliding frame 39, it is necessary to overcome the elastic force of the second spring 43, and then the guide rod 42 encounters a certain resistance when moving back and forth along the bent guide groove 55, slowing down the speed at which the guide rod 42 slides along the bent guide groove 55, and then slowing down the falling speed of the second box body 2. At the same time, the falling speed of the C-shaped rod 6 and the third box body 3 is slowed down, avoiding the second box body 2 and the third box body 3 from being damaged by excessive impact force when they contact the fixed support plate 61 due to excessive falling speed.

[0055] After the second and third boxes 2 and 3 land on the fixed support plate 61, they stop moving downward. The guide rod 42 moves to the lower end of the curved guide groove 55, pushing open the baffle 57 and entering the lower end of the vertical guide groove 56. The baffle 57 then returns to its original position under the action of the torsion spring, shielding the lower end of the curved guide groove 55. The rectangular slide 39 stops its left-right reciprocating motion, and the nozzle holder 26 stops spraying sterile gas. The instruments on the multiple mounting frames 14 are now completely dry. The first aid kit is now in the third state, meaning the upper end surfaces of the first, second, and third boxes 1 and 3 are on the same horizontal plane. The upper end surfaces of the first, second, and third boxes 1 and 3 form an operating surface, providing ample space for first aid operations. One end of the limiting channel 53 communicates with the through slot 11, and the other end communicates with the limiting groove 58.

[0056] During the movement of the second box body 2 from the first state to the third state, the disinfection, flushing and drying processes are completed, which effectively saves emergency time and eliminates the need for personnel to perform disinfection before removing the instrument for use.

[0057] like Figure 18 As shown, the handle 22 is then pulled to the right, causing the first limit plate 12 to move rightward, the iron connecting plate 13 and the instrument placement module to move rightward, and the iron connecting plate 13 and the magnet 40 to separate. The first limit plate 12 gradually enters the limit channel 53, and the iron connecting plate 13 and the instrument placement module then move through the through slot 11 into the limit channel 53. The iron connecting plate 13 and the mounting frame 14 enter the through slot 11 and gradually move to a horizontal position. This continues until the right end of the first limit plate 12 enters the limit groove 58 and the limit pin 24 engages the latch slot 59. At this point, the instrument placement module is within the limit channel 53. The second limiting plate 15 and the shielding plate 16 enter the through slot 11 and assume a horizontal position, with a portion of the second limiting plate 15 located within the limiting passage 53. At this point, the second limiting plate 15 and the shielding plate 16 block the through slot 11 and the connection between the disinfection chamber 10 and the through slot 11, preventing magazines from falling into the disinfection chamber 10. At this point, the first limiting plate 12 is immobilized by the limiting pin 24. Because the second limiting plate 15 is located between the through slot 11 and the limiting passage 53, the second housing 2 cannot move upward. Furthermore, due to the restraints of the first housing 1 and the C-shaped rod 6, the second housing 2 cannot move left or right, thereby securing the second housing 2 to the first housing 1. The first limiting plate 12 is positioned between the limiting groove 58 and the limiting channel 53, preventing the third housing 3 from moving upward. Furthermore, the third housing 3 is secured to the first housing 1 by the limiting mechanism of the first housing 1 and the C-shaped rod 6, facilitating operation on the work surface formed by the first housing 1, the second housing 2, and the third housing 3. The instrument placement module is secured horizontally within the limiting channel 53, with the movable clamping plate 18 positioned above the fixed clamping plate 17, making it easier for personnel to access instruments.

[0058] When taking out an instrument, the corresponding movable clamp 18 is pulled upward to release the clamping of the instrument, and then the instrument is taken out.

[0059] When a clean instrument is fixed to the mounting frame 14 for standby use, the movable splint 18 is pulled upward by the buckle 19, so that the movable splint 18 is away from the fixed splint 17, and the instrument is placed in the instrument limiting groove 21, and then the buckle 19 is released, and the movable splint 18 moves downward under the action of the tension spring 20 to clamp the instrument.

[0060] It should be noted that the first limiting plate 12, the iron connecting plate 13, the mounting frame 14, and the second limiting plate 15 should be adapted to the limiting channel 53. When the first limiting plate 12, the iron connecting plate 13, the mounting frame 14, and the second limiting plate 15 are in the limiting channel 53, they are all kept in a horizontal fixed state and cannot move freely under the limiting action of the limiting channel 53 and the limiting pin 24, thereby preventing the second limiting plate 15 and the shielding plate 16 from separating from the second box body 2 and affecting the fixed state of the second box body 2. This also prevents the horizontal instrument placement module from bending due to the upward pulling of the movable splint 18 when taking the instrument, thereby affecting the taking.

[0061] After the first aid is completed, when the device needs to be stored and carried, the user holds the handle 22 with his hand and pulls the slide plate 23 upward with his fingers, thereby disengaging the limit pin 24 from the latch slot 59. Then, the handle 22 is moved in the direction closer to the first box body 2, thereby causing the shielding plate 16, the second limit plate 15, the multiple installation frames 14, the iron connecting plate 13, and the first limit plate 12 to slide into the disinfection chamber 10 in sequence. After the shielding plate 16, the second limit plate 15, the multiple installation frames 14, and the iron connecting plate 13 enter the disinfection chamber 10, they will rotate to a vertical state under the action of gravity, and then the first limit plate 12 will continue to move, causing the iron connecting plate 13 to be attracted to the magnet 40. At this time, the user can stop pushing the handle 22.

[0062] Afterwards, the second and third boxes 2 and 3 are pulled upward, and the guide rod 42 moves upward along the first gas passage 46. At this time, due to the limitation of the curved guide groove 55, the baffle 57 cannot rotate into the curved guide groove 55, so the guide rod 42 can only move upward along the vertical guide groove 56. This allows the second and third boxes 2 and 3 to move upward quickly, speeding up the storage process.

[0063] At the same time, the C-shaped rod 6 moves upward along the slider 5. When the C-shaped rod 6 reaches the top of the limiting slide 4, the second and third boxes 2 and 3 cannot move upward any further. The second and third boxes 2 and 3 are then pushed closer to each other. The first and second slides 8 and 9 both move toward the fixed stop 701, and the second and third boxes 2 and 3 return to their initial positions.

[0064] When the first slide 8 moves close to the fixed stopper 701, the liquid piston cylinder 28 moves close to the liquid piston rod 29, and the disinfectant in the liquid storage tank 27 enters the liquid piston cylinder 28 through the fifth liquid channel 37, the fourth liquid channel 35, and the second liquid one-way valve 36 for standby use.

[0065] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
