In addition, the first sliding rail 214 is connected with a strip-shaped bearing portion 216 on the outward side.

[0041] The upper cabinet body 100 is internally provided with an upper placing rack 300 on the partition plate 210, which is mainly used for storing reagents in smaller containers with a volume of less than 1L. For example Figure 1As shown in the drawings, the upper cabinet body 100 is approximately cuboid in the closed state, and has a first movable assembly and a second movable assembly symmetrically arranged on both sides. The first movable assembly and the second movable assembly are folded to the middle to form an integrated upper cabinet body 100, and can be flipped to the sides to open the upper cabinet body 100 and form experimental tables on both sides. In this embodiment, the movable assemblies on both sides are approximately the same in structure, and are composed of a top plate 140, a first side plate 110, a second side plate 120, and a third side plate 130. The second side plate 120 of the first movable assembly is arranged on the side away from the second movable assembly, and is approximately rectangular. The middle of one end of the second side plate 120 is protruding, and a first hinge shaft 121 is arranged at the protruding part. The two ends of the first hinge shaft 121 extend from the two sides of the protruding part, and are rotatably arranged in two first hinge seats 212 below, so that the second side plate 120 is hinged to the partition plate 210 and can rotate relative to the partition plate 210. The middle of the other end of the second side plate 120 is also protruding, and a second hinge shaft 122 is arranged at the protruding part. The two ends of the second hinge shaft 122 extend from the two sides of the protruding part, and are connected to the top plate 140 above. On the other two sides of the second side plate 120, one side is arranged with two second hinge seats 123 symmetrically above and below at a position close to the two ends, and is connected to the first side plate 110 in front. The other side is integrally connected to the third side plate 130 behind. Furthermore, the top plate 140 is approximately rectangular. Two third hinge seats 141 are symmetrically arranged at the two ends of the side of the top plate 140 connected to the second side plate 120. The second hinge shaft 122 is rotatably arranged in the third hinge seat 141, so that the top plate 140 and the second side plate 120 are hinged to each other. The bottom of the top plate 140 is arranged with a groove 142 extending inward from the other side opposite to the third hinge seat 141. A support plate 143 is slidably arranged in the groove 142. The inward side of the support plate 143 is connected to the inner wall of the groove 142 through two telescopic rods 144. When the upper cabinet body 100 is opened, the support plate 143 can be extended out of the groove 142 through the telescopic rods 144 to form the fulcrum of the experimental table at both ends. Furthermore, the middle of the side of the first side plate 110 connected to the second side plate 120 is protruding, and is arranged with a third hinge shaft 111. The two ends of the third hinge shaft 111 extend from the two sides of the protruding part, and are rotatably arranged in two second hinge seats 123 in front of the second side plate, so that the first side plate 110 and the second side plate 120 are hinged and can rotate relative to each other. The first side plate 110 is also arranged with a plurality of windows 112 for observing the inside of the upper cabinet body 100.The third side plate 130 of the embodiment is fixed opposite to the second side plate 120, and rotates together with the second side plate 120 in the process of opening the upper cabinet 100, and protrudes upward in the experiment table. A plurality of hooks and ring hangers are arranged on the inner side of the third side plate 130, and the hooks and ring hangers are used as the placing components of the experimental instruments. The upward position of the hooks and ring hangers can facilitate the operator to store and take various experimental tools and containers.

[0042] A specific working mode of the embodiment is as follows:

[0043] When the storage cabinet of the embodiment is used as a storage device, the first movable assembly and the second movable assembly are folded, the first side plates 110 on both sides are placed on the bearing portions 216 to limit the first hinge shafts 121, the support plates 143 in the top plates 140 on one side are extended out through the telescopic rods 144 and inserted into the grooves 142 on the other side to fix the top plates 140 on both sides, thereby limiting the second hinge shafts 122. After the top plates 140 on both sides are fixed, the rotation of the first side plates 110 is blocked, thereby simultaneously limiting the third hinge shafts 111, and a stable upper cabinet 100 is formed. When the storage cabinet of the embodiment is used as an experiment table device, the support plates 143 inserted into the grooves 142 on the other side are withdrawn. Then, the first hinge shafts 121 and the second hinge shafts 122 can be rotated to the sides to unfold the first movable assembly and the second movable assembly. After unfolding, the second side plates 120 are rotated to the horizontal positions on both sides of the lower cabinet 200, and the top plates 140 are rotated to the vertical positions outside the second side plates 120. Then, the telescopic rods 144 in the top plates 140 drive the support plates 143 to extend and abut against the ground, and the fixing of the experiment table is completed. After that, the third hinge shafts 111 are rotated to open the front side of the experiment table, and the operator can freely take the reagents on the upper placing rack 300 and use the second side plates 120 as the table top to perform experiments.

[0044] In the embodiment, the laboratory storage device is provided with the upper cabinet 100 with the two sides that can be combined and separated, and the stable lower cabinet 200. The first side plates 110, the second side plates 120 and the top plates 140 of the upper cabinet 100 are hingedly connected with each other, and the telescopic support plates 143 arranged in the top plates 140 are used to realize that the upper cabinet 100 in the open state can be used as an experiment table without affecting the operator to take reagents, thereby solving the problem that the leaf type cabinet door of the laboratory storage cabinet in the prior art easily collides and blocks the operator, causes waste of chemical reagents and brings safety hazards.

[0045] Meanwhile, in the embodiment, the interior space of the upper cabinet 100 can be fully opened by changing the activity, so that the four sides of the upper shelf 300 are exposed when the upper cabinet 100 is opened. When the reagent on the upper shelf 300 needs to be taken, the reagents placed at different positions will not block each other, and various reagents can be conveniently taken from the front, back, left and right directions.

[0046] In addition, in the embodiment, a first locking mechanism 240 is arranged at the middle of the side where the first sliding door 220 and the second sliding door 230 are close to each other, and the first locking mechanism 240 is used to close the lower cabinet 200 in a non-use state, thereby improving the storage safety. In the embodiment, a second locking mechanism 115 is arranged at the bottom of the side where the two second side plates 120 on the first movable assembly and the second movable assembly are close to each other, and the second locking mechanism 115 is used to close the upper cabinet 100 in a non-use state, thereby also improving the storage safety. Meanwhile, a first bolt hole 113 is arranged at the top of the first side plate 110 and at a position close to the center of the upper cabinet 100, a bolt 114 is inserted into the first bolt hole 113, and a second bolt hole 145 is arranged at a position opposite to the first bolt hole 113 on the side of the top plate 140. In the closed and opened states of the upper cabinet 100, the first bolt hole 113 and the second bolt hole 145 can be aligned, so that the relative fixed docking between the top plate 140 and the first side plate 110 can be realized by the bolt 114 in the two states, thereby avoiding the rotation of the second hinge shaft 122 and the third hinge shaft 111.

[0047] In the embodiment, the second side plate 120 is also provided with a second sliding rail 124 close to the second hinge seat 123, the second sliding rail 124 is arranged in parallel with the third hinge shaft 111, and the second sliding rail 124 is provided with a second sliding groove 125. When the upper cabinet 100 is opened, the second sliding groove 125 opens downward, and the second sliding rail 124 can be relatively docked with the first sliding rail 214, so that when the first sliding door 220 and the second sliding door 230 are separated to the left and right to open the lower cabinet 200, the sliding blocks 250 on the two sides are also simultaneously slid into the second sliding grooves 125 on the two sides, so that the second side plates 120 on the two sides are relatively fixed with the lower cabinet in the opened state of the upper cabinet 100, and the overall structure of the experiment table in the opened state is more stable. Meanwhile, in the embodiment, one end of the sliding block 250 extending into the groove has an outward extension part protruding to the two sides, and the bottoms of the first sliding groove 215 and the second sliding groove 125 are also recessed to the two sides, which are matched with the shape of the sliding block 250, so that the sliding block 250 can be stably embedded in the first sliding groove 215 and the second sliding groove 125.

[0048] In one or more other embodiments, the support plate 143 and the telescopic rod 144 can also be arranged at other positions on the upper cabinet 100, and the telescopic rod 144 can also be replaced by other telescopic mechanisms.
