[0030] As Figure 1-8 shown, a double-layer structure drawer of the present utility model includes a drawer body 1, and a horizontal partition 2 is arranged on the drawer body 1;

[0031] An upper drawer assembly 3, including a frame 31 arranged on the horizontal partition 2 and a front panel 32 arranged at the front of the frame 31, is used for performing upper and lower layering processing on the storage space inside the drawer body 1;

[0032] A connection assembly 4 is movably arranged on both sides of the front panel 32 and is used for switching the opening mode of the drawer body 1 and the upper drawer assembly 3. With such a design, through the horizontal partition 2 horizontally spaced inside the drawer body 1 and the upper drawer assembly 3 supported and fixed by welding a support spring 35 on the horizontal partition 2, a double-layer structure inside the drawer body 1 is realized, which can provide more storage space in a limited space, thereby maximizing the utilization rate of the laboratory.

[0033] It should be noted that the surfaces in contact with the inside of the drawer body 1 at the outer ends of both sides of the frame 31 are structures composed of slide rails and chutes.

[0034] In one embodiment, the upper drawer assembly 3 further includes support plates 33 disposed on opposite sides of the frame 31, the support plates 33 are provided with push-down studs 34 for contacting the surface of the transverse partition 2, and the bottom corners of the frame 31 are provided with support springs 35 for fixing on the transverse partition 2. With this design, through the support plates 33 welded on opposite sides of the frame 31, and the internal thread grooves that are turned on the end faces of the support plates 33 and cooperate with the external threaded parts of the push-down studs 34, the push-down studs 34 can be operated to rotate and descend in sequence, so that the transverse partition 2 contacting the bottom surface of the push-down studs 34 descends downward under the support elasticity of the support springs 35 welded at the end corners thereof, which not only realizes the upper and lower stratification inside the drawer body 1, but also can relatively adjust the height to achieve the effect of storing more specifications of items in the laboratory.

[0035] In one embodiment, the frame 31 is evenly provided with a plurality of longitudinally distributed embedding grooves 36, and the embedding grooves 36 are plugged with the partition plates 6. In this design, the embedding grooves 36 are provided on the frame 31 at equal intervals and in the longitudinal direction by turning, and the partition plates 6 are integrally formed with embedding blocks that match the embedding grooves 36 on both sides, and the embedding grooves 61 on the partition plates 6 can be combined in a direct plug-in manner, so that the internal space of the frame 31 can be divided according to the size of the items, and the storage requirements of the items of the corresponding size in the frame 31 can be met.

[0036] It should be noted that a plurality of partition plates 6 are provided and the lengths of the partition plates 6 are different.

[0037] In one embodiment, the connection assembly 4 includes a connection plate 41 disposed on the inner side of the front panel 32, a notch 42 disposed on the connection plate 41, a fixing pin 43 movably disposed on the notch 42, an end block 44 movably disposed at the front end of the fixing pin 43, and a handle 45 movably disposed on the side of the end block 44. In this design, by means of the connection plate 41 designed on the inner side of the front panel 32, the notch 42 machined on the connection plate 41, and the fixing pin 43 movably disposed in the notch 42, when the fixing pin 43 moves to the position as shown in the figure, the fixing pin 43 can be moved to the inner side of the front panel 32. Figure 6 state, the drawer body 1 can be pulled out while separating the drawer body 1 and the upper drawer assembly 3; when the fixing pin 43 moves to the position as shown in FIG. Figure 7 state, the drawer body 1 and the upper drawer assembly 3 can be linked to close, and in the locked state, the drawer body 1 and the upper drawer assembly 3 are synchronously pulled out; when the fixing pin 43 moves to the position as shown in FIG. Figure 8 In the three states, the upper drawer assembly 3 can be pulled out while the drawer body 1 and the upper drawer assembly 3 are separated. Different opening methods are selected to meet the needs of different laboratory workflows.

[0038] It should be noted that the front end of the fixing pin 43 is a end block 44 connected by a rotating shaft, which can rotate around the central axis of the fixing pin 43 to change the position of the handle 45, facilitating the left and right movement of the fixing pin 43 within the limit groove assembly 5. The handle 45 horizontally arranged on the end block 44 and connected by a rotating shaft can be folded or turned up, achieving the effect of fixing the fixing pin 43 on the surface of the drawer body 1 connected to the front panel 32.

[0039] In one embodiment, the upper panel structure of the drawer body 1 is provided with a groove for accommodating the front panel 32. At the side of the groove and corresponding to the notch one 42, a limit groove assembly 5 connected to the front panel 32 is provided. The limit groove assembly 5 includes a notch two 51 having the same specification as the notch one 42, and a limit groove 52 is communicatively provided at the open outer part of the notch two 51. With such a design, through the groove machined on the upper panel structure of the drawer body 1 and mating with the outside of the front panel 32, and the notch two 51 machined on the side of the groove and on the upper panel structure of the drawer body 1 and communicatively connected to the side of the front panel 32, and the notch two 51 is communicatively connected to the notch one 42, and the limit groove 52 communicatively connected outside the notch two 51, the position can be fixed while cooperating with the movement of the fixing pin 43.

[0040] It should be noted that the inner groove shape of the limit groove 52 is two round holes at both ends connected by a straight groove in the middle, and the inner diameter of the two round holes at both ends is greater than the height of the straight groove in the middle.

[0041] Preferably, the outer diameter of the fixing pin 43 is matched with the inner diameters of the straight grooves on the notch one 42, the notch two 51, and the limit groove 52.

[0042] In one embodiment, the drawer body 1 is also provided with a plurality of longitudinally distributed and equally spaced first embedded grooves 36. With such a design, through the longitudinally distributed and equally spaced first embedded grooves 36 machined in the drawer body 1 in the same way as inside the frame 31, one or more partition plates 6 can be used to partition the lower space separated by the horizontal partition plate 2 within the drawer body 1, meeting the stability storage requirements for items of corresponding specifications.

[0043] In one embodiment, a square opening 7 for slidably connecting with the frame 31 is provided at the rear end of the drawer body 1. With such a design, through the square opening 7 machined at the rear end of the drawer body 1, when the drawer body 1 is horizontally moved outwards, the separation of the drawer body 1 and the upper drawer assembly 3 can be achieved, enabling the operation of separately pulling out the drawer body 1.

[0044] In one embodiment, a plurality of sets of second grooves 61 for inserting and combining one or more partition plates 6 are uniformly arranged on two separated end faces of the partition plate 6. With such a design, through the second grooves 61 formed on the two separated end faces of the partition plate 6 by turning, a plurality of partition plates 6 can be freely assembled, realizing the horizontal partitioning of space and having the stability for storage.

[0045] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
