Description

Technical Field

[0002] A first aid kit is a container for storing first aid supplies, usually containing various medical supplies and medicines. It is used for initial first aid treatment in emergency situations. Its purpose is to provide timely initial treatment for the injured, reduce the severity of the injury, and buy time for subsequent professional treatment.

[0003] In order to ensure the effective implementation of the rescue operation, various medical instruments and medicines are placed inside the first aid box. The traditional first aid box is just a separate storage box, which leads to the disorder of the storage of medical instruments and medicines, and it is very inconvenient for medical staff to take medical supplies. Although there are multi-layer storage first aid box structures on the market, the storage boxes of each layer of this multi-layer storage first aid box have deviations in the height direction, and it is impossible to intuitively present the medical supplies of each layer in front of the medical staff, resulting in the medical staff still needing to find medical supplies in storage boxes of different heights. In addition, since emergency work is generally tense, it is difficult for medical staff to place the first aid box, which will cause a violent collision between the first aid box and the ground or other supporting surfaces. Due to the impact of the collision, the medical instruments or medicines inside the first aid box will be subject to greater vibration, which is easy to cause damage to the instruments or spillage of the medicines, so a multifunctional first aid box is developed.

[0029] like Figure 1-Figure 3As shown, a multifunctional first aid box comprises a box body 1, the upper end of the box body 1 is an open structure and is equipped with a box cover 2 adapted thereto, two sets of adapted lock buckles 3 are symmetrically fixedly installed between the box cover 2 and the front side end of the box body 1, the box cover 2 is hingedly connected to the rear side end of the box body 1 by two sets of symmetrically arranged hinges 4, and a handle 5 is fixedly arranged in the middle of the outer side of the top plate of the box cover 2. When the box cover 2 is closed, the box cover 2 is fixedly connected to the box body 1 by the two sets of lock buckles 3, and the staff can hold the handle 5 to move the entire first aid box.

[0030] A shock-absorbing base 6 is provided at the bottom of the box body 1. Specifically, the inner peripheral wall of the shock-absorbing base 6 is slidably matched with the outer peripheral wall of the box body 1. A plurality of vertical second springs 7 are evenly spaced in a rectangular array between the upper part of the bottom plate of the shock-absorbing base 6 and the lower part of the bottom plate of the box body 1. The upper and lower ends of each second spring are respectively fixedly connected to the bottom plate of the box body 1 and the bottom plate of the shock-absorbing base 6. In addition, a plurality of limiting slide grooves 8 are evenly spaced on the upper part of the outer peripheral wall of the shock-absorbing base 6, and a plurality of limiting heads 9 that are slidably matched with each of the limiting slide grooves 8 are fixedly provided at the lower part of the outer peripheral wall of the box body 1.

[0031] Rectangular passage slots 10 are respectively provided in the upper halves of the left and right side panels of the box body 1, and two first storage boxes 11 are symmetrically slidably arranged inside the box body 1 at positions corresponding to the two passage slots 10, and a translation drive mechanism for driving the two first storage boxes 11 to move relative to or away from each other is provided on the box body 1.

[0032] Two buffer pads 12 corresponding to the two first storage boxes 11 are symmetrically arranged on the box cover 2, and a plurality of connecting rods 13 are evenly arranged on the upper part of each of the buffer pads 12 in a rectangular array. The end of each of the connecting rods 13 away from the buffer pad 12 is slidably matched with a small-diameter sliding hole 14 opened on the top plate of the box cover 2. The top plate of the box cover 2 is provided with a large-diameter sliding hole 15 connected to the small-diameter sliding hole 14 on the inner side of the small-diameter sliding hole 14. The end of each of the connecting rods 13 extends to the inside of the large-diameter sliding hole 15 and is fixedly provided with a sliding seat 16 slidably matched with the large-diameter sliding hole 15. Each of the connecting rods 13 is sleeved with a first spring 17 at the position between the buffer pad 12 and the top plate of the box cover 2.

[0033] like Figures 3 to 5As shown, in this embodiment, the translation drive mechanism includes a bidirectional screw 18 horizontally rotatably mounted inside the box 1 and located below the two first storage boxes 11, and a first knob 19 disposed outside the box 1 for driving the bidirectional screw 18 to rotate. Specifically, a transmission box 20 is fixedly mounted below the passage slot 10 on the corresponding side on the outside of the box 1, and a driving shaft 21 is vertically rotatably mounted on the transmission box 20. The upper end of the driving shaft 21 is rotatably connected to the top plate of the transmission box 20, the lower end of the driving shaft 21 extends to the outside of the transmission box 20 and is fixedly sleeved with the first knob 19, and a driving bevel gear 23 is mounted in the middle of the driving shaft 21. A driven shaft 24 is fixedly connected to one end of the bidirectional screw 18 close to the transmission box 20, and the driven shaft 24 is rotatably connected to the side wall of the box 1, and its free end extends to the inside of the transmission box 20 and is mounted with a driven bevel gear 25 adapted to the driving bevel gear 23. The external threads at both ends of the bidirectional screw 18 have opposite rotation directions, and threaded sleeves 26 threadedly connected to the bidirectional screw 18 are fixedly disposed at the lower parts of the opposite ends of the two first storage boxes 11 .

[0034] By turning the first knob 19, the bidirectional screw 18 is driven to rotate. Since the threaded sleeves 26 at the bottom of the two first storage boxes 11 are respectively matched with the outer spirals at both ends of the bidirectional screw 18, the two first storage boxes 11 move relatively along the two passage slots and slide out to the outside of the box body 1. In addition, two limiting protruding rings 27 are symmetrically fixedly provided in the middle of the bidirectional screw 18. When the first knob 19 is rotated in the opposite direction, the two first storage boxes 11 slide downward until the threaded sleeves 26 at the lower parts of the two first storage boxes 11 contact the limiting protruding rings 27 at the corresponding ends, and the two first storage boxes 11 completely enter the interior of the box body 1.

[0035] The box body 1 is symmetrically provided with two second storage boxes 28 below the two first storage boxes 11, and the symmetry lines of the two second storage boxes 28 are perpendicular to the symmetry lines of the two first storage boxes 11. Specifically, the two second storage boxes 28 are symmetrically arranged along the bidirectional screw 18, and the box body 1 is provided with a lifting drive mechanism for driving the two second storage boxes 28 to move synchronously up and down.

[0036] like Figure 2As shown, in the present embodiment, the lifting drive mechanism includes a transmission shaft 29 which is horizontally rotatably installed in the middle of the open end of the box body 1 and is perpendicular to the bidirectional screw 18. One end of the transmission shaft 29 extends to the outside of the box body 1 and is fixedly sleeved with a second knob 30 for driving its rotation. The transmission shaft 29 is respectively fixedly sleeved with transmission gears 31 at the positions close to the front and rear inner walls of the box body 1, and the two second storage boxes 28 are respectively fixedly installed with transmission racks 32 meshing with the transmission gear 31 on one side close to the front and rear inner walls of the box body.

[0037] When the two first storage boxes 11 slide out of the box body, the transmission shaft 29 can be driven to rotate by turning the second knob 30, and the two transmission gears 31 mesh with the two transmission racks 32 on the two second storage boxes 28, respectively, so that the two second storage boxes 28 move upward to the upper opening end of the box body 1. When the first aid operation is completed, the second knob 30 is rotated in the opposite direction, so that the two second storage boxes 28 move downward to the bottom of the box body 1.

[0038] In addition, two limiting slide rails 33 are symmetrically fixedly provided on the front and rear inner side walls of the box body 1, and two limiting sliders 34 are fixedly installed on the two second storage boxes 28, which are matched with the two limiting slide rails 33 on the corresponding sides. In this embodiment, the cross section of each limiting slide rail 33 is T-shaped, and each limiting slider 34 is provided with a limiting slide hole with a T-shaped cross section that is matched with the limiting slide rail 31. The two groups of limiting sliders 34 are slidably matched with the limiting slide rails 33 on the box body 1, so that the stability of the lifting and lowering movement of the two second storage boxes 28 can be ensured.

[0039] As a further improvement to this embodiment, a locking mechanism is provided on the outer side of the box body 1 to prevent the second knob 30 from rotating automatically. Figure 6As shown, specifically: the locking mechanism includes a mounting plate 35 fixedly mounted on the front side plate of the box body 1 and perpendicular to the outer side plate of the box body, a locking rod 36 opposite to the second knob 30 is slidably mounted on the mounting plate 35, and a locking hole 37 capable of plugging and cooperating with the locking rod 36 is provided on the peripheral wall of the second knob 30. A limited pull head 38 is fixedly arranged at one end of the locking rod 36 away from the second knob 30, a connecting convex ring 39 is arranged at the position of the locking rod 36 close to the second knob 30, and a third spring 40 is sleeved at the position of the locking rod 36 between the mounting plate 35 and the connecting convex ring 39, and the two ends of the third spring 40 are respectively fixedly connected to the mounting plate 35 and the connecting convex ring 39. When the second knob 30 needs to be rotated, the staff can pull the limit pull head 38 and the locking rod 36 in the direction away from the second knob 30, so that the locking rod 36 is disengaged from the locking hole 37 on the second knob 30, and the locking rod 36 will not affect the rotation of the second knob 30. When the two second storage boxes 28 are moved to the open end of the box body 1 by rotating the second knob 30, the locking rod 36 is facing the locking hole 37 of the second knob 30. After the operator releases the force on the limit pull head 38, the locking rod 36 is pushed to slide in the direction close to the second knob 30 under the action of the reset elastic force of the third spring 40 until the locking rod 36 is plugged into the locking hole 37 on the second knob 30, thereby preventing the second knob 30 from rotating on its own and ensuring the stability of the two second storage boxes 28 after they are raised.

[0040] The present invention can realize the classification and storage of medical instruments and drugs required for emergency operations by setting two first storage boxes and two second storage boxes. When applied to on-site emergency operations, after the staff opens the box cover of the first aid box, they can drive the bidirectional screw to rotate by turning the first knob, so that the two first storage boxes move relatively along the two passages and slide out to the outside of the box. Then, the transmission shaft is driven to rotate by turning the second knob, and under the meshing action of the two transmission gears and the two transmission racks on the two second storage boxes, the two second storage boxes are synchronously moved upward to the upper opening end of the box. Thereby, the four storage boxes are quickly and synchronously unfolded at the same height, so that the medical instruments and drugs classified and stored in the first aid box are uniformly and intuitively displayed in front of medical staff, which is convenient for medical staff to take the medical instruments and drugs, and can achieve timely and rapid response to emergency operations, thereby improving the efficiency and convenience of emergency operations.

[0041] In addition, the present invention provides a shock-absorbing base and a protective pad at the bottom of the box body and inside the box cover of the first aid box, respectively, which can preferentially cushion the vibration force exerted on the inside of the box body when the first aid box collides violently with the outside, thereby improving the protection function of medical instruments and drugs stored inside the box body.

[0042] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
