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] See also Figures 1 to 9 The present invention provides a technical solution: a vehicle-mounted medical first aid kit, comprising a box body 1 and a box cover 3 arranged thereon, an inner frame 4 for supporting surgical instruments is arranged inside the box body 1, a plurality of sets of universal wheels 24 for transportation are arranged below the box body 1, and a transformation structure for driving the box body 1 to switch between a mobile mode and a stable mode is arranged on the box body 1;

[0036] The transformation structure includes a vertical through slot 25 opened on the box body 1 and corresponding to the position of the universal wheel 24, a lower base plate 6 is fixedly connected to the inner wall of the box body 1, and a lifting component for adjusting the horizontal height of the inner frame 4 according to the functional mode of the box body 1 is provided on the lower base plate 6;

[0037] The side wall of the box body 1 is provided with two sets of table panels 5 arranged symmetrically, the box body 1 is provided with a leveling groove 26 for accommodating the table panels 5, and the box body 1 is provided with a plate assembly for driving the table panels 5 to freely deflect in the vertical direction according to the functional mode of the box body 1;

[0038] The plurality of sets of universal wheels 24 expose the vertical through slots 25 in the mobile mode, and the box body 1 is provided with a pressing component for adjusting the height of the plurality of sets of universal wheels 24 .

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, when the medical devices are stored in the box 1, the multiple sets of universal wheels 24 arranged at the bottom of the box 1 can meet the dual requirements of convenience and functionality of the box 1. At the same time, when the box cover 3 is opened to take out the medical devices for medical operations such as sorting, counting or operation (such as simple suturing or dressing replacement) of the medical devices, the universal wheels 24 can be retracted into the box 1, so that the bottom of the box 1 is directly in contact with the supporting surface such as the ground or a desktop, so as to ensure that after the box 1 is opened, it can maintain its stability and prevent the medical devices placed therein from tilting and causing contamination.

[0040] At the same time, in the initial state, the multiple sets of universal wheels 24 expose the vertical through grooves 25 in the mobile mode, and the inner frame 4 for supporting the medical device is completely in the box 1. The inner frame 4 is driven to move in the vertical direction by the lifting component, and then the horizontal height of the inner frame 4 is gradually increased, so that the medical devices placed in the inner frame 4 can be exposed from the box 1, thereby facilitating medical staff to take or place medical devices, so that medical staff can quickly access the required items.

[0041] Furthermore, when the inner frame 4 moves upward, the multiple sets of universal wheels 24 under the box body 1 can be retracted into the box body 1 under the drive of the pressure assembly. At this time, as the universal wheels 24 retract, the universal wheels 24 will no longer contact the placement surface, but will drive the bottom of the box body 1 to directly contact the placement surface, thereby ensuring the stability of the medical device during the process of taking or storing.

[0042] Among them, when the lifting component drives the height of the inner frame 4 to gradually increase, it can synchronously drive the expansion plate component to operate, and under the drive of the expansion plate component, it can drive the two groups of table panels 5 set on both sides of the box body 1 to synchronously deflect in the vertical direction until the inner frame 4 reaches the maximum height. The back panel 5 can reach the deflection end position, and the table panel 5 is at a right angle to the side wall of the box body 1 at the deflection end position, that is, when the placement surface is horizontal, the table panel 5 can be deflected to a horizontal state.

[0043] It should be noted that the table panel 5 is flush with the outer surface of the box body 1 in the mobile mode, wherein a leveling groove 26 for accommodating the table panel 5 is provided on the box body 1. When the box cover 3 is closed, the medical box is in the mobile mode, and the mobile mode is the storage or transportation process of medical equipment. In the mobile mode, the table panel 5 is completely in the leveling groove 26 and can be flush with the outer surface of the box body 1, thereby completing the storage process of the table panel 5 and reducing the protrusions on the outer surface of the box body 1, which can prevent the table panel 5 from being damaged by excessive collisions.

[0044] When the box cover 3 is opened and the height of the inner frame 4 is raised, the medical box is in a stable mode, which indicates the process of taking, placing or using medical equipment. In the stable mode, the universal wheels 24 retract into the box body 1, and the table panel 5 can be deflected to a horizontal state, and provide a temporary work surface for the temporary storage or use of medical equipment, so that in emergency situations or in ambulances or cabin hospitals or tent hospitals with limited space, basic medical operations such as sorting, counting and operation of medical equipment (such as simple suturing or dressing changes) can be effectively performed, thereby improving the efficiency of the preparation operation of medical equipment.

[0045] In one of the more preferred embodiments, the lifting assembly includes a worm 7 driven by a motor and freely rotating in the horizontal direction, the worm 7 rotates on a fixed axis on the lower base plate 6, and a plurality of groups of isotope rods 10 arranged in a circular array are provided on the outer peripheral side of the worm 7, and the plurality of groups of isotope rods 10 swing freely and synchronously in the vertical direction, and a connecting rod 11 is provided at the top end of the isotope rod 10 for fixed axis rotation, and the end of the connecting rod 11 away from the isotope rod 10 rotates on a fixed axis on the inner frame 4.

[0046] The worm 7 is meshed with multiple sets of worm wheels 8, and the lower base plate 6 is fixedly connected to multiple sets of side support plates 28. The worm wheels 8 rotate on the side support plates 28, and a U-shaped side frame 9 is fixedly connected to the side of the worm wheel 8 facing the side support plate 28. The U-shaped side frame 9 is fixedly connected to the same position rod 10.

[0047] The inner wall of the box body 1 includes an integrally formed corner step 2 .

[0048] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the worm 7 is driven by a motor to rotate horizontally on the lower substrate 6, thereby driving a plurality of worm gears 8 meshing with the worm 7 and arranged in a ring array to rotate synchronously. The top axis of the worm gear 8 rotates on the side support plate 28, and the side support plate 28 is fixed to the lower substrate 6 by bolts, thereby ensuring the stability of the worm gear 8 during rotation.

[0049] Among them, multiple groups of worm gears 8 rotate synchronously in the vertical direction, and the side surfaces of the worm gears 8 are fixedly connected to the U-shaped side frame 9. Therefore, when the worm gear 8 rotates, the isotropic rod 10 can be driven to rotate on a fixed axis through the U-shaped side frame 9, and a freely deflectable connecting rod 11 is provided between the isotropic rod 10 and the inner frame 4. When the isotropic rod 10 rotates following the worm gear 8, the isotropic rod 10 can be driven to deflect in the vertical direction. In addition, multiple groups of connecting rods 11 jointly support the inner frame 4, and when the isotropic rod 10 rotates, the horizontal height of the inner frame 4 can be changed.

[0050] It should be noted that, in actual use, the outer side surface of the inner frame 4 is in sliding contact with the inner wall of the box body 1, thereby avoiding an excessive gap between the two, which would cause external debris to fall and hinder the height change process of the inner frame 4. At the same time, it can ensure the stability of the inner frame 4 when it is raised or lowered, and when the inner frame 4 is at its lowest height, its lower part avoids interference with the corner step 2. Therefore, the corner step 2 can limit the lowest height of the inner frame 4 and provide supporting force for the inner frame 4, so as to avoid the isotropic rod 10 and the connecting rod 11 being subjected to large forces for a long time and reducing their service life.

[0051] On the basis of the lifting assembly embodiment, the extension plate assembly includes a trapezoidal positioning plate 12 fixedly connected to the inner wall of the box body 1, and the trapezoidal positioning plate 12 is provided with a Z-shaped push plate 16 that can move freely in the horizontal direction and swing freely at the end position of the movement, and the Z-shaped push plate 16 is fixedly connected to the table panel 5;

[0052] The box body 1 is provided with a clearance groove 27 corresponding to the swing position of the Z-shaped push plate 16 .

[0053] The housing 1 is provided with a transverse shaft 13 which is freely rotatable in the vertical direction and is transmission-connected to the worm 7. The transverse shaft 13 is fixedly rotated on the housing 1. An active swing rod 14 is coaxially fixed on the transverse shaft 13. A driven swing rod 15 is provided on the active swing rod 14. Both ends of the driven swing rod 15 are respectively fixedly rotated on the active swing rod 14 and the Z-shaped push plate 16.

[0054] The Z-shaped push plate 16 is fixedly connected with a rear pin 17 and a front pin 18, the trapezoidal positioning plate 12 is provided with a horizontal slide groove 19 for sliding connection between the rear pin 17 and the front pin 18, and the trapezoidal positioning plate 12 is provided with an arcuate slide groove 20 for sliding connection between the rear pin 17.

[0055] The terminal end of the horizontal slide groove 19 facing the table panel 5 is the rotation center point of the Z-shaped push plate 16 , and the middle part of the horizontal slide groove 19 is connected with the end of the arc-shaped slide groove 20 .

[0056] like Figure 4 , Figure 7 and Figure 8 As shown, when the worm 7 rotates freely in the horizontal direction, it can drive the transverse shaft 13 connected thereto to rotate in the vertical direction, wherein the two can change the transmission direction of the output shaft through the meshing relationship between the bevel gears, and synchronously realize the synchronous rotation of the worm 7 and the transverse shaft 13 through the transmission cooperation between the pulleys, wherein when the transverse shaft 13 rotates, it can drive the active rocker arm 14 fixed thereon to rotate synchronously, and the rotation of the active rocker arm 14 drives the driven rocker arm 15 to deflect.

[0057] At the same time, in the initial state, the table panel 5 is completely in the horizontal groove 26. At this time, the front pin 18 is at the junction of the horizontal slide groove 19 and the arc slide groove 20, and the rear pin 17 is at the head end position of the horizontal slide groove 19. With the deflection of the driven rocker arm 15, the rear pin 17 and the front pin 18 first slide on the horizontal slide groove 19, and then the Z-shaped push plate 16 moves in the horizontal direction to drive the table panel 5 to gradually move away from the side wall of the box body 1 and finally completely break away from the Z-shaped push plate 16.

[0058] Furthermore, as the active rocker arm 14 continues to rotate, the leading pin 18 slides to the terminal position of the horizontal slot 19, but the driven rocker arm 15 continues to deflect, and then the rear pin 17 slides on the arc slot 20 at this time, and slides to the end position of the arc slot 20 facing the table panel 5 as the active rocker arm 14 rotates. At the same time, as the rear pin 17 slides on the arc slot 20, the Z-shaped push plate 16 deflects in the vertical direction, and drives the table panel 5 fixedly connected thereto to deflect synchronously, and when the rear pin 17 is at the end position of the table panel 5, the table panel 5 is at the end position of the deflection, that is, it is in a horizontal state.

[0059] It should be noted that when the leading pin 18 slides to the terminal position of the driven rocker arm 15, the rear pin 17 is at the junction of the horizontal slide groove 19 and the arc-shaped slide groove 20. Therefore, when the active rocker arm 14 rotates later, the rear pin 17 can be driven to slide on the arc-shaped slide groove 20, but the position of the leading pin 18 does not change. Therefore, the leading pin 18 is the rotation center point of the Z-shaped push plate 16, and only when the leading pin 18 is at the end of the horizontal slide groove 19, the angle between the leading pin 18 and the box body 1 will change as the active rocker arm 14 rotates in the vertical direction, so that when the medical box is in a stable mode, it can provide a horizontal working surface for the medical equipment through the extension process of the table panel 5 to meet the temporary storage or preparation of the medical equipment.

[0060] On the basis of the embodiment of the extension plate assembly, the pressing assembly includes an upper pressing plate 22 and a lower pressing plate 23 arranged on the inner wall of the box body 1, the upper pressing plate 22 and the lower pressing plate 23 overlap and are arranged alternately in the vertical direction, and the upper pressing plate 22 and the lower pressing plate 23 are both fixedly rotated on the inner wall of the box body 1;

[0061] The lower surfaces of the upper abutment plate 22 and the lower abutment plate 23 are flush and fixedly connected with a set of universal wheels 24 . The lower surface of the inner frame 4 is fixedly connected with an end arc plate 21 , and the end arc plate 21 is in sliding contact with the upper surface of the upper abutment plate 22 .

[0062] like Figure 1 , Figure 4 and Fig. 9As shown, when the medical box is in the mobile mode, the inner frame 4 is completely in the box body 1, that is, the inner frame 4 is at the lowest horizontal height. At this time, the end arc plate 21 fixedly arranged below the inner frame 4 is squeezed and abutted against the upper abutment plate 22, and the upper abutment plate 22 can synchronously press the lower abutment plate 23 to drive the upper abutment plate 22 and the lower abutment plate 23 to be in a horizontal state in the mobile mode, and the universal wheels 24 respectively arranged on the universal wheels 24 and the lower abutment plate 23 can expose the vertical through grooves 25 and contact the supporting surface, so as to meet the convenience of transporting the medical box in the mobile mode.

[0063] It should be noted that the box body 1 is provided with two sets of torsion springs that respectively drive the upper abutment plate 22 and the lower abutment plate 23 to return to the initial deflection angle. The torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure. In the mobile mode, the end arc plate 21 squeezes the upper abutment plate 22, and synchronously squeezes the lower abutment plate 23 through the upper abutment plate 22. At this time, the upper abutment plate 22 and the lower abutment plate 23 are deflected, so that the universal wheel 24 is exposed to a certain height of the bottom plate of the box body 1 through the vertical through groove 25, so that it can directly contact the support surface.

[0064] At the same time, when the medical box switches from the mobile mode to the stable mode, the height of the inner frame 4 is increased under the drive of the lifting assembly, and the end arc plate 21 is driven to move upward synchronously, so that the end arc plate 21 is reduced and eventually loses the squeezing force on the upper support plate 22. At this time, the upper support plate 22 and the lower support plate 23 respectively resume upward deflection under the action of the torsion spring, and during the deflection process, the distance between the box body 1 and the support surface gradually decreases until the universal wheel 24 is completely retracted into the box body 1, and the bottom plate of the box body 1 can contact the support surface, thereby ensuring the stability of the box body 1 in the stable mode to prevent the medical device from shaking or overturning during the process of taking, placing or using.

[0065] 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.
