Description

Technical Field

[0001] This invention relates to the field of laboratory management technology, and in particular to a modern biological laboratory management device. Background Technology

[0002] Modern biological laboratories are places for conducting experiments, the production sites of science and technology, the cradle of science, the base of scientific research, and the source of technological development. They play a very important role in the development of science and technology, so the country invests a lot in laboratories. With the increasing number of scientific research institutions and universities, laboratories have become an indispensable and important institution around us. The various reagents in the laboratory are necessary materials to ensure that we can complete scientific research work. Therefore, the management of reagents is of paramount importance.

[0003] In existing laboratories, reagent cabinets are usually used to manage and store reagents. However, the reagents placed in the cabinets are often placed in a disorderly manner, which makes it very inconvenient for users to take out the reagents placed high up. Directly taking out the reagents deep in the cabinet may cause them to bump into the reagents on the outside, resulting in them being knocked over. Usually, a stool is needed to assist, which is very troublesome. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a modern biological laboratory management device to address the issue that existing laboratories typically use medicine cabinets to manage and store reagents. However, the reagents in these cabinets are often placed haphazardly, making it very inconvenient for users to retrieve reagents placed high up. Directly taking reagents from deep within the cabinet can easily result in bumping into outer reagents and causing them to tip over, usually requiring the use of a stool for assistance, which is a very troublesome problem.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A modern biological laboratory management device includes a cabinet. A partition is fixedly connected between the upper and lower inner walls of the cabinet, forming multiple storage slots between the partition and the cabinet.

[0008] Preferably, the front of the cabinet has an annular groove, and a mounting frame is movably connected inside the annular groove. The cabinet door is fixedly connected to the mounting frame by hinges, and multiple springs are fixedly connected between the mounting frame and the inner wall of the annular groove.

[0009] Preferably, the forward and backward moving assembly includes a first motor fixedly connected to the inner wall of the back of the storage compartment, a fixing block fixedly connected to the rear side of the lower surface of the rectangular frame, a lead screw fixedly connected to the output end of the first motor, the lead screw passing through the fixing block and fixedly connected to a limit block, and the lead screw being threadedly connected to the fixing block.

[0010] Preferably, sliders are fixedly connected to the inner walls of the left and right sides of the upper storage slot, and grooves are provided on the left and right sides of the rectangular frame. The sliders are adapted to the grooves, and a gap is left between the rectangular frame and the inner bottom wall of the storage slot.

[0011] Preferably, the lifting assembly includes a U-shaped frame fixedly connected to the upper surface of a rectangular frame, a motor housing fixedly connected to the right inner wall of the U-shaped frame, a rotating shaft rotatably connected between the motor housing and the left inner wall of the U-shaped frame via a bearing, a winding reel fixedly connected to the outer surface of the rotating shaft, and a steel wire rope wound around the outer surface of the winding reel.

[0012] Preferably, a second motor is fixedly connected to the inner bottom wall of the motor housing, a worm gear is fixedly connected to the output end of the second motor, the worm gear is meshed with a worm wheel, and the right end of the rotating shaft is located inside the motor housing and fixedly connected to the worm wheel.

[0013] Preferably, vertical plates are fixedly connected to both the left and right sides of the upper surface of the storage box, a horizontal plate is fixedly connected to the top of the vertical plates, and the bottom end of the steel wire rope is fixedly connected to the horizontal plate.

[0014] Preferably, a first fixed rod and a second fixed rod are fixedly connected between the U-shaped frame and the inner wall of the rectangular frame, respectively. A plurality of X-shaped rods are provided between the first fixed rod and the second fixed rod. One end of the upper side of the X-shaped rod is rotatably connected to the first fixed rod by a pin, and the other end of the upper side of the X-shaped rod is rotatably connected to a first movable block by a pin. A first long groove is opened on the right side of the first fixed rod, and the first movable block is slidably connected in the first long groove. One end of the lower side of the X-shaped rod is rotatably connected to the second fixed rod by a pin, and the other end of the lower side of the X-shaped rod is rotatably connected to a second movable block by a pin. A second long groove is opened on the right side of the second fixed rod, and the second movable block is slidably connected in the second long groove.

[0015] Preferably, a panel is fixedly connected to the front of the rectangular frame, and a first button and a second button are installed on the front of the panel. A cavity is opened inside the bottom of the cabinet, and a storage battery is installed inside the cavity. The first button and the first motor are electrically connected to the storage battery through wires, and the second button and the second motor are electrically connected to the storage battery through wires.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up lifting components and forward and backward moving components, the medicine is placed in the storage box when in use. When it is necessary to retrieve the medicine in the upper storage box, the forward and backward moving components make the storage box and rectangular frame extend out of the storage slot, and then the lifting components lower the storage box, so as to conveniently retrieve the medicine deep in the cabinet, and it is not easy to bump into the medicine on the outside, thus avoiding the possibility of tipping over. It is very convenient to use.

[0018] By incorporating a spring, the mounting frame can slide within the annular groove when the cabinet door is impacted. The spring provides cushioning during the sliding process, thus preventing the medicines inside the cabinet from tipping over.

[0019] By setting a first motor to drive the lead screw to rotate, since the lead screw is threadedly connected to the fixed block, the lead screw can drive the fixed block and the rectangular frame to move forward during the rotation. During the movement of the rectangular frame, the storage box and medicine can be extended out of the storage slot.

[0020] By setting a rotating shaft to drive the winding wheel to rotate, the winding wheel can loosen the steel wire rope during the rotation. At this time, the items in the storage box will fall down and be easily retrieved.

[0021] By setting a second motor to drive the worm to rotate, the worm can drive the shaft to rotate during the rotation process by cooperating with the worm wheel. The self-locking of the worm and worm wheel prevents the shaft from rotating randomly.

[0022] By setting multiple X-shaped rods, when the storage box moves downward, one end of the X-shaped rod on the upper and lower sides rotates around the pin, and the other end slides in the first long groove and the second long groove respectively. At this time, the movement of the storage box can be guided to avoid shaking. Attached Figure Description

Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0035] The present invention provides a modern biological laboratory management device in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0036] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0037] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0038] It is understood that the meanings of “on”, “above” and “above” in this disclosure should be interpreted in the broadest sense, such that “on” means not only “directly on” something, but also includes something with an intermediary feature or layer, and that “above” or “above” means not only “on” something, but also includes something “above” or “above” without an intermediary feature or layer.

[0039] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings.

[0040] like Figure 1-8 As shown, an embodiment of the present invention provides a modern biological laboratory management device, including a cabinet 1. A partition 2 is fixedly connected between the upper and lower inner walls of the cabinet 1. A plurality of storage slots 3 are formed between the partition 2 and the cabinet 1. A rectangular frame 4 is provided inside the upper storage slot 3 through a front-back moving component. A baffle 5 is fixedly connected between the left and right inner walls of the lower storage slot 3. A storage box 6 is provided inside the rectangular frame 4. A lifting component 7 is provided above the rectangular frame 4 for raising and lowering the storage box 6.

[0041] By setting up the lifting component 7 and the front-to-back moving component, the medicine is placed in the storage box 6 when in use. When the medicine in the upper storage box 6 needs to be retrieved, the front-to-back moving component makes the storage box 6 and the rectangular frame 4 extend out of the storage slot 3. Then the lifting component 7 lowers the storage box 6, so as to conveniently retrieve the medicine deep in the cabinet 1 and avoid bumping into the medicine on the outside, thus preventing it from being knocked over. It is very convenient to use.

[0042] like Figure 1 As shown, in this embodiment, cabinet doors 101 are installed on both the left and right sides of the front of the cabinet 1, and transparent glass 102 is installed on the cabinet doors 101.

[0043] The transparent glass 102 facilitates observation of the medicines inside the cabinet 1, while the cabinet door 101 protects the medicines inside the cabinet 1.

[0044] like Figures 1-4 As shown, in this embodiment, an annular groove 103 is provided on the front of the cabinet 1, and an installation frame 104 is movably connected inside the annular groove 103. The cabinet door 101 is fixedly connected to the installation frame 104 by a hinge, and multiple springs 105 are fixedly connected between the installation frame 104 and the inner wall of the annular groove 103.

[0045] By setting a spring 105, when the cabinet door 101 is impacted, the mounting frame 104 can be driven to slide in the annular groove 103. The mounting frame 104 is buffered by the spring 105 during the sliding process, thereby preventing the medicines in the cabinet 1 from tipping over.

[0046] like Figure 1 and Figure 3 As shown, in this embodiment, the forward and backward moving component includes a first motor 301 fixedly connected to the inner wall of the back side of the storage slot 3, a fixing block 302 fixedly connected to the rear side of the lower surface of the rectangular frame 4, a lead screw 303 fixedly connected to the output end of the first motor 301, the lead screw 303 passing through the fixing block 302 and fixedly connected to a limit block 304, and the lead screw 303 and the fixing block 302 are threadedly connected.

[0047] By setting the first motor 301 to drive the lead screw 303 to rotate, since the lead screw 303 is threadedly connected to the fixed block 302, the lead screw 303 can drive the fixed block 302 and the rectangular frame 4 to move forward during the rotation. During the movement, the rectangular frame 4 can drive the storage box 6 and the medicine to extend out of the storage slot 3.

[0048] like Figure 5 and Figure 6 As shown, in this embodiment, sliders 305 are fixedly connected to the inner walls of the left and right sides of the upper storage slot 3, and grooves 306 are provided on the left and right sides of the rectangular frame 4. The sliders 305 and the grooves 306 are adapted to each other, and a gap is left between the rectangular frame 4 and the inner bottom wall of the storage slot 3.

[0049] By setting the slider 305 and the groove 306, the movement of the rectangular frame 4 is made more stable, preventing the rectangular frame 4 from rotating with the lead screw 303.

[0050] like Figure 1 and Figure 6 As shown, in this embodiment, the lifting component includes a U-shaped frame 401 fixedly connected to the upper surface of the rectangular frame 4. A motor housing 402 is fixedly connected to the inner right wall of the U-shaped frame 401. A rotating shaft 403 is rotatably connected between the motor housing 402 and the inner left wall of the U-shaped frame 401 via a bearing. A winding wheel 404 is fixedly connected to the outer surface of the rotating shaft 403. A steel wire rope 405 is wound around the outer surface of the winding wheel 404.

[0051] By setting the rotating shaft 403 to drive the winding wheel 404 to rotate, the winding wheel 404 can loosen the steel wire rope 405 during the rotation. At this time, the items in the storage box 6 fall down and are very convenient to take out.

[0052] like Figure 6 and Figure 7 As shown, in this embodiment, a second motor 406 is fixedly connected to the inner bottom wall of the motor housing 402, a worm gear 407 is fixedly connected to the output end of the second motor 406, a worm wheel 408 is meshed with the worm gear 407, and the right end of the rotating shaft 403 is located inside the motor housing 402 and is fixedly connected to the worm wheel 408.

[0053] By setting a second motor 406 to drive the worm 407 to rotate, the worm 407, in conjunction with the worm wheel 408, can drive the rotating shaft 403 to rotate during the rotation. The self-locking mechanism of the worm 407 and the worm wheel 408 allows the rotating shaft 403 to rotate freely.

[0054] like Figure 1 and Figure 6 As shown, in this embodiment, vertical plates 601 are fixedly connected to both the left and right sides of the upper surface of the storage box 6, and horizontal plates 602 are fixedly connected to the top of the vertical plates 601. The bottom end of the steel wire rope 405 is fixedly connected to the horizontal plate 602.

[0055] The vertical plate 601 and the horizontal plate 602 facilitate the fixing of the wire rope 405 to the storage box 6.

[0056] like Figure 6 and Figure 8As shown, in this embodiment, a first fixed rod 8 and a second fixed rod 9 are fixedly connected between the U-shaped frame 401 and the inner wall of the rectangular frame 4, respectively. A plurality of X-shaped rods 10 are provided between the first fixed rod 8 and the second fixed rod 9. One end of the upper side of the X-shaped rod 10 is rotatably connected to the first fixed rod 8 through a pin, and the other end of the upper side of the X-shaped rod 10 is rotatably connected to a first movable block through a pin. A first long groove 11 is opened on the right side of the first fixed rod 8, and the first movable block is slidably connected in the first long groove 11. One end of the lower side of the X-shaped rod 10 is rotatably connected to the second fixed rod 9 through a pin, and the other end of the lower side of the X-shaped rod 10 is rotatably connected to a second movable block through a pin. A second long groove 12 is opened on the right side of the second fixed rod 9, and the second movable block is slidably connected in the second long groove 12.

[0057] By setting multiple X-shaped rods 10, when the storage box 6 moves downward, one end of the X-shaped rods 10 on the upper and lower sides rotates around the pin, and the other end slides in the first long groove 11 and the second long groove 12 respectively. At this time, the movement of the storage box 6 can be guided to avoid shaking.

[0058] like Figure 3 and Figure 8 As shown, in this embodiment, a panel 13 is fixedly connected to the front of the rectangular frame 4. A first button 14 and a second button 15 are installed on the front of the panel 13. A cavity 16 is opened inside the bottom of the cabinet 1. A storage battery 17 is installed inside the cavity 16. The first button 14 and the first motor 301 are electrically connected to the storage battery 17 through wires. The second button 15 and the second motor 406 are electrically connected to the storage battery 17 through wires.

[0059] By setting the storage battery 17, the first button 14 is activated to rotate the first motor 301, and the second button 15 is activated to rotate the second motor 406.

[0060] The technical solution provided by this invention, by setting up a lifting component 7 and a front-to-back moving component, allows medicines to be placed in the storage box 6 during use. When medicines need to be retrieved from the upper storage box 6, the front-to-back moving component causes the storage box 6 and the rectangular frame 4 to extend out of the storage slot 3, and then the lifting component 7 lowers the storage box 6, thereby making it easy to retrieve medicines deep inside the cabinet 1 without easily touching medicines on the outside and avoiding tipping over. It is very convenient to use.

[0061] By setting a spring 105, when the cabinet door 101 is impacted, the mounting frame 104 can be driven to slide in the annular groove 103. The mounting frame 104 is buffered by the spring 105 during the sliding process, thereby preventing the medicines in the cabinet 1 from tipping over.

[0062] By setting the first motor 301 to drive the lead screw 303 to rotate, since the lead screw 303 is threadedly connected to the fixed block 302, the lead screw 303 can drive the fixed block 302 and the rectangular frame 4 to move forward during the rotation. During the movement, the rectangular frame 4 can drive the storage box 6 and the medicine to extend out of the storage slot 3.

[0063] By setting the rotating shaft 403 to drive the winding wheel 404 to rotate, the winding wheel 404 can loosen the steel wire rope 405 during the rotation. At this time, the items in the storage box 6 fall down and are very convenient to take out.

[0064] By setting a second motor 406 to drive the worm 407 to rotate, the worm 407, in conjunction with the worm wheel 408, can drive the rotating shaft 403 to rotate during the rotation. The self-locking of the worm 407 and the worm wheel 408 prevents the rotating shaft 403 from rotating arbitrarily.

[0065] By setting multiple X-shaped rods 10, when the storage box 6 moves downward, one end of the X-shaped rods 10 on the upper and lower sides rotates around the pin, and the other end slides in the first long groove 11 and the second long groove 12 respectively. At this time, the movement of the storage box 6 can be guided to avoid shaking.
