[0037] In further embodiments, as shown in Figure 2 , Figure 6 and Figure 7 , the rebounding piece 35 includes a top column 351 and a spring 352, the top column 351 has two corresponding mounting grooves 37 arranged at the top of the first storage box 31 and the second storage box 32, the number of springs 352 is the same as the number of top columns 351 and one-to-one correspondence, the spring 352 is arranged in the corresponding mounting groove 37, the two ends of the spring 352 are fixedly arranged with the bottom of the mounting groove 37 and the bottom of the top column 351, respectively, and the top surface of the top column 351 is arranged in a semicircular arc shape;

[0038] When the second storage box 32 is horizontally rotated above the first storage box 31, the bottom of the second storage box 32 will press the top column 351 in the mounting groove 37 at the top of the first storage box 31 downward into the corresponding mounting groove 37, and at the same time, the spring 352 in the corresponding mounting groove 37 will be compressed. When the second storage box 32 is horizontally rotated above the first storage box 31, and the second storage box 32 and the first storage box 31 are in the stacked state, at this time, the compressed spring 352 in the mounting groove 37 at the top of the first storage box 31 will drive the corresponding top column 351 upward into the first clamping groove 321 arranged at the bottom of the second storage box 32, so as to clamp the second storage box 32 above the first storage box 31, thereby achieving a self-locking function. The third storage box 33 and the second storage box 32 also have the same self-locking function.

[0039] In further embodiments, as shown in Figure 4 and Figure 10As shown, the first receiving box 31 and the second receiving box 32 are respectively provided with a first slot 311 and a second slot 322 on the same side of the inner wall of the first receiving box 31 and the second receiving box 32, the first receiving box 31 is provided with a first plug 5 on one side of the bottom of the first receiving box 31, the second receiving box 32 is provided with a second plug 6 on one side of the bottom of the second receiving box 32, the first plug 5 is matched with the first slot 311, and the second plug 6 is matched with the second slot 322.

[0040] With reference to Figure 4 When the four corners of the second receiving box 32 are coaxially arranged with the four corners of the first receiving box 31, the first plug 5 on the bottom of the second receiving box 32 is located on one side adjacent to the first slot 311 arranged on the inner wall of the first receiving box 31, and when the four corners of the third receiving box 33 are coaxially arranged with the four corners of the second receiving box 32, the second plug 6 on the bottom of the third receiving box 33 is located on one side adjacent to the second slot 322 arranged on the inner wall of the second receiving box 32.

[0041] With reference to Figure 10 When the second receiving box 32 is unfolded by rotating horizontally outward above the first receiving box 31, the first plug 5 on the bottom of the second receiving box 32 is embedded in the first slot 311 arranged on the inner wall of the first receiving box 31, and when the third receiving box 33 is unfolded by rotating horizontally outward above the second receiving box 32, the second plug 6 on the bottom of the third receiving box 33 is embedded in the second slot 322 arranged on the inner wall of the second receiving box 32, the first slot 311 and the first plug 5 are matched, the second receiving box 32 and the first receiving box 31 can be temporarily clamped together after the second receiving box 32 is unfolded, the second slot 322 and the second plug 6 are matched, the third receiving box 33 and the second receiving box 32 can be temporarily clamped together after the third receiving box 33 is unfolded, so as to avoid the second receiving box 32 and the third receiving box 33 from being randomly moved after being unfolded, thereby affecting the unfolding effect.

[0042] In further embodiments, with reference to Figure 8As shown, the lifting mechanism 4 comprises a support frame 41, a support rod 42, a support sleeve 43 and a connecting plate 44, the support frame 41 is symmetrically arranged on both sides of the first-aid box body 1, and the bottom of each support frame 41 is in abutment with the bottom of the article placing part 3 in the first-aid box body 1, the support rod 42 is vertically arranged in the middle of the first-aid box body 1, and a sliding block 421 is arranged on the support rod 42 and can slide up and down, the support sleeve 43 is coaxially arranged on the outside of the support rod 42, the bottom of the support sleeve 43 is fixedly connected with the top of the sliding block 421 on the support rod 42, and a handle 431 is arranged on the top of the support sleeve 43 for pulling, and the connecting plate 44 is arranged on both sides of the sliding block 421, and each connecting plate 44 is fixedly connected with the support frame 41;

[0043] When the medical staff needs to move the article placing part 3 in the first-aid box body 1 to the outside of the first-aid box body 1, first, the medical staff opens the box cover 2, and then holds the handle 431 on the top of the support sleeve 43 to pull it upwards, so as to drive the support sleeve 43 to move upwards on the outside of the support rod 42, since the top of the sliding block 421 on the support rod 42 is fixedly connected with the bottom of the support sleeve 43, and the sliding block 421 can slide up and down on the support rod 42, when the support sleeve 43 moves upwards, the sliding block 421 will be driven to slide upwards on the support rod 42, and the two support frames 41 are fixedly connected with the two sides of the sliding block 421 through the two connecting plates 44, so that when the sliding block 421 slides upwards on the support rod 42, the two support frames 41 and the article placing part 3 on the two support frames 41 can be simultaneously driven to move upwards in the first-aid box body 1 to a specified position, thereby facilitating the medical staff to unfold the article placing part 3.

[0044] When it is needed to put the article placing part 3 back into the first-aid box body 1, only need to fold the unfolded article placing part 3 to the original unfolded state, and then the medical staff holds the handle 431 on the top of the support sleeve 43 to press it downwards, so as to drive the sliding block 421 at the bottom of the support sleeve 43 and the support frame 41 to move along the support rod 42 to the bottom of the first-aid box body 1, thereby moving the article placing part 3 on the support frame 41 to the inside of the first-aid box body 1.

[0045] In a further embodiment, a linear groove 432 is formed in the side wall of the support sleeve 43, and a limiting pin 422 is arranged on one side of the side wall of the support rod 42 close to the top, and the front end of the limiting pin 422 extends into the linear groove 432 formed in the support sleeve 43;

[0046] When the support sleeve 43 moves up to a specified position on the support rod 42, the limit pin 422 on the support rod 42 will contact the bottom of the linear slot 432 on the side wall of the support sleeve 43, so that the support sleeve 43 cannot continue to move up, thereby avoiding the support sleeve 43 from being separated from the top end of the support rod 42.

[0047] The above merely describes the embodiments of the present application and is not intended to limit the present application. The present application can be variously changed and altered by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of claims of the present application.
