Description

Technical Field

[0001] This invention belongs to the field of experimental equipment technology, specifically relating to a lightweight experimental carrying case, and also to an operating method for the lightweight experimental carrying case. Background Technology

[0002] Experiments involve the use of numerous experimental equipment and tools, and laboratory storage boxes are devices for storing these items. However, existing storage boxes suffer from the following problems: 1. Experimental equipment such as reagents, test tubes, and other instruments and tools are often randomly placed within the storage box, potentially leading to reagent errors, experimental failure, or even serious accidents. 2. Other experimental equipment and tools require constant coordination during experiments, necessitating frequent retrieval, which wastes considerable time and disrupts the continuity of the experiment. 3. Test tubes used in experiments may undergo chemical reactions after reagent mixing, sometimes producing harmful substances. Failure to promptly clean these substances poses a safety hazard. Furthermore, untreated dry waste generated during experiments can cause laboratory hygiene problems. Therefore, this invention proposes a lightweight laboratory carrying case and its operating method to solve the aforementioned problems. Summary of the Invention

[0003] This invention provides a lightweight laboratory carrying case that is easy to carry, has a rational internal layout, clearly categorizes all experimental equipment, and allows for the display of each piece of equipment inside the case, reducing the time spent by researchers retrieving equipment, ensuring experimental continuity, and enabling timely disposal of waste generated during experiments, thus avoiding laboratory hygiene problems. This invention also provides a method for operating the lightweight laboratory carrying case, the specific scheme of which is as follows:

[0004] A lightweight laboratory carrying case includes a case body with an openable and closable lid, and the lid is removable. Inside the case body, a low-temperature section, a room-temperature section, and a waste disposal section are arranged in parallel. The low-temperature section and the room-temperature section are separated by partitions, and the room-temperature section and the waste disposal section are separated by partitions. The low-temperature section has several racks for holding reagent kits, and the racks are retractable. The room-temperature section has a test tube area, a general area, and a hanging area. The case body also has a small laboratory equipment storage area.

[0005] Furthermore, the side walls and lower parts of the partitions of the box located in the low-temperature section are horizontally equipped with rotating rods. A box that can hold refrigerant is rotatably connected to the rotating rods on both sides. Several box racks that can hold reagent kits are set directly above the box. Telescopic components are rotatably connected to the side walls on opposite sides of each pair of box racks. Telescopic components are also rotatably connected to the side walls on opposite sides of the box and box racks.

[0006] Furthermore, the test tube area includes a storage box 1 located on the bottom surface of the box body, and a test tube rack is provided inside the storage box 1. The test tube rack is detachably connected to the storage box 1. The general area includes a storage box 2 located directly above the storage box 1. Several baffles are provided between the opposite side walls of the storage box 2. The hanging area includes a storage box 3 located directly above the storage box 2. Several hanging parts are provided on the opposite side walls of the storage box 3. The hanging frame consists of a fixing block, two elastic arc-shaped locking blocks connected to the fixing block, and an elastic guide block connected to the end of the elastic arc-shaped locking blocks. The lids of the storage boxes 1, 2, and 3 can all be opened and closed.

[0007] Furthermore, the waste disposal section includes dry waste bins and liquid waste bins arranged side by side. Each side of the dry waste bin has a vertically formed elongated groove on its sidewall and partition sidewall. Each side of the dry waste bin has a slider that matches the groove. The dry waste bin has a pressure plate, and each pressure plate has horizontally formed blind holes on opposite sides. Each blind hole contains a compression spring with one end fixed to it, and each end of the compression spring is connected to a pressure ball. Vertical grooves are formed on the opposite sidewalls of the dry waste bin. The liquid waste bin has two sliding grooves, each with several holes spaced apart for placing pressure beads. A waste disposal opening is provided on the pressure plate, and a cover plate is hinged to the waste disposal opening to close it. Long, narrow sliding grooves are vertically provided on the side walls of the bin and the partition side walls on both sides. Sliding blocks matching the sliding grooves are provided on both sides of the liquid waste bin. A lid is provided on the liquid waste bin, and a threaded through hole is provided on the lid, with a matching nut on the threaded through hole.

[0008] Furthermore, the low-temperature section, the normal-temperature section, and the waste treatment section are connected to the lower part of the side panel of the container by a flip-down mechanism. The side panel is provided with a locking mechanism, which includes two opposing rack blocks inside the side panel. A gear meshes with the rack blocks between them. The gear is rotated by a rotating rod, one end of which extends to the outside of the side panel. Locking rods are horizontally connected to both ends of the rack blocks, and they pass through the side panel and extend to the outside of the side panel. A telescopic spring is sleeved on the end of each locking rod away from the rack blocks. Holes suitable for the ends of the locking rods to penetrate are opened on both sides of the container wall on both sides of the side panel.

[0009] Furthermore, the small experimental equipment placement area is located on the lid of the box, and the small experimental equipment placement area includes a clamping mechanism and a storage box.

[0010] Furthermore, the clamping mechanism includes two opposing clamping seats detachably connected to the cover plate. Both clamping seats are provided with arc-shaped clamping blocks. A clamping rod is horizontally connected to one clamping block, and the clamping rod passes through the clamping block and the clamping seat. An arc-shaped clamping block is also connected to the end of the clamping rod at the front end of the clamping block. A compression spring is sleeved on the clamping rod between the clamping block and the clamping block.

[0011] Furthermore, the upper parts of the opposite side walls of the box are rotatably connected with retaining rings, and a shoulder strap is connected between the two retaining rings.

[0012] Furthermore, the enclosure is made of a thin, light-shielding material.

[0013] A method for operating a lightweight laboratory carrying case includes the following steps:

[0014] Step 1: First, open and remove the box lid and place it. Then, turn the rotating rod. The gear drives the two rack blocks to move relative to each other. The two locking rods move away from the holes on the side wall of the box, and the side panel opens. Then, pull the top shelf. Under the action of the telescopic rod, the distance between the two shelves gradually increases. Then, rotate it to one side of the side panel. At this time, each shelf is tilted. Then, take out the reagent kits required for the experiment from the shelf. Then, take out storage box one, storage box two, and storage box three in sequence, and place each shelf, storage box one, storage box two, and storage box three one by one.

[0015] Step 2: Remove the cover plate on the dry waste bin and the nut on the liquid waste bin. Put the waste and liquid generated in the experiment into the bins respectively. When there is a lot of dry waste, press the pressure plate so that the pressure beads on both sides of the pressure plate gradually descend along the two sliding grooves until the pressure beads are stuck into the placement holes, thereby compressing the dry waste and increasing the space in the dry waste bin.

[0016] Step 3: Pour the waste generated during the experiment into the dry waste bin and the liquid waste bin respectively. After the experiment, empty the waste and put it back in its original place. Then put all the experimental equipment back into the box in the order they were taken out.

[0017] The beneficial effects of this invention are:

[0018] 1. The chamber is divided into a low-temperature section, a normal-temperature section, and a waste disposal section, so that various experimental equipment can be placed in a categorized manner, avoiding the disorderly placement of experimental equipment;

[0019] 2. By setting up several boxes and telescopic rods, the space between each pair of boxes is enlarged when the boxes are stretched. Pulling the boxes towards the side panel makes each box approach a flat state, which facilitates the retrieval of multiple reagent kits. It can also be used to place reagent kits in experiments. By setting up storage box one, storage box two, and storage box three, all experimental equipment commonly used in experiments can be placed in categories, avoiding confusion due to a large number of experimental equipment. Placing them one by one also makes it easier for experimental personnel to reduce the time spent retrieving experimental equipment and avoid mis-picking, ensuring the continuity of experiments.

[0020] 3. By setting up a separate low-temperature section, it is convenient to preserve experimental reagents and avoid the failure to properly preserve experimental reagents that require low temperatures.

[0021] 4. By setting up dry waste bins and liquid waste bins, the experimental waste generated during the experiment was ensured to be classified and packaged separately, thus ensuring the hygiene of the laboratory environment and avoiding some safety hazards. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] See Figure 1-13A lightweight laboratory carrying case includes a case body 1 with an openable and closable lid 101. The lid 101 is detachable, allowing the case to be laid flat during experiments. This facilitates access to the small experimental equipment storage area 7 located on the lid 101. Inside the case body 1, a low-temperature section 2, a room-temperature section 3, and a waste disposal section 4 are arranged in parallel. The low-temperature section 2 is designed for convenient storage of experimental reagents, ensuring proper preservation of reagents requiring freezing, and can also hold other experimental reagents. The waste disposal section 4 prevents the indiscriminate disposal of experimental waste, thus protecting the laboratory environment and ensuring the safety of experimental personnel, especially considering the potential hazards of some liquid mixtures generated during experiments. Partitions 5 separate the low-temperature section 2 from the room temperature section 3 and from the waste disposal section 4. The separation of partitions 5 facilitates the separate storage of various experimental supplies. The low-temperature section 2 is equipped with several racks 6 for holding reagent kits. The racks 6 are used to hold various reagent kits. Different reagent kits are placed on different racks 6 to avoid confusion when taking out reagents during experiments. The racks 6 are also retractable. The room temperature section 3 is equipped with a test tube area 31, a general area 32 and a hanging area 33. Test tubes are commonly used experimental tools. The test tube area 31 can hold test tubes of various sizes. The general area 32 can hold other experimental supplies. The hanging area 33 can hang cylindrical or long strip-shaped experimental tools. The box 1 is also equipped with a small experimental equipment storage area 7.

[0037] The side wall of the chamber 1 in the low-temperature section 2 and the lower part of the partition 5 are both horizontally equipped with rotating rods 8. A box 9 for holding refrigerant is rotatably connected to the rotating rods 8 on both sides. Ice packs or other refrigerants can be placed inside the low-temperature zone box 9. Several racks 6 for holding reagent kits are set directly above the box 9. Telescopic components 10 are rotatably connected to the side walls of each pair of racks 6 on opposite sides. Telescopic components 10 are also rotatably connected to the side walls of the box 9 and the racks 6 on opposite sides. When taking out a reagent kit, pull the top rack 6. Under the action of the telescopic components 10, the distance between each pair of racks 6 increases. The racks 6 are then pulled towards the side panel 102, and each rack 6 will form a planar shape. The reagent kit can then be taken out. This planar shape formed by each rack 6 can also be used directly for placing reagent kits, which is convenient for taking out reagents during experiments, avoiding the problem of taking the wrong reagent, and improving the experimental progress.

[0038] The test tube area 31 includes a storage box 311 located on the bottom surface of the box 1. The storage box 311 contains a test tube rack 312, which is detachably connected to the storage box 311. The general area 32 includes a storage box 321 located directly above the storage box 311. Several baffles 322 are spaced between the opposite side walls of the storage box 321. The hanging area 33 includes a storage box 331 located directly above the storage box 321. Several hanging parts 332 are provided on the opposite side walls of the storage box 331. Each hanging part 332 consists of a fixing block 3321, two elastic arc-shaped locking blocks 3322 connected to the fixing block 3321, and an elastic guide block 3323 connected to the end of the elastic arc-shaped locking block 3322. The lids of the storage boxes 311, 321, and 331 can all be opened and closed.

[0039] The waste disposal section 4 includes a dry waste bin 41 and a liquid waste bin 42 arranged side by side. The dry waste bin 41 has vertically formed elongated grooves 411 on both sides of its body 1 and partition 5. Each side of the dry waste bin 41 has a slider 412 that matches the groove 411. The dry waste bin 41 has a pressure plate 413, with horizontally formed blind holes on opposite sides. Each blind hole contains a compression spring 414, one end of which is fixed to the spring. Each compression spring 414 has a pressure bead 415 connected to its end. The dry waste bin 41 also has vertically formed grooves 2 on opposite sides of its inner sidewalls. Each groove 2 has several holes spaced apart for placing pressure beads. The pressure plate 413 has a waste disposal opening, which is hinged to a... The cover plate 416 of the garbage inlet is closed. Long strip-shaped sliding grooves 421 are vertically opened on the side walls of the box 1 and the partition side walls on both sides of the liquid garbage bin 42. Sliding blocks 3 that match the sliding grooves 421 are provided on both sides of the liquid garbage bin 42. The liquid garbage bin 42 is equipped with a bin lid 422. The bin lid 422 is provided with a threaded through hole and a matching nut 423. The cover plate on the dry garbage bin 41 and the nut 423 on the liquid garbage bin 42 are removed. The garbage and liquid generated in the experiment are put into them respectively. When there is a lot of dry garbage, the pressure plate 413 is pressed, so that the pressure beads 415 on both sides of the pressure plate 413 gradually descend along the two sliding grooves until the pressure beads 415 are stuck into the placement hole, thereby compressing the dry garbage and increasing the space of the dry garbage bin.

[0040] The low-temperature section 2, the normal-temperature section 3, and the waste disposal section 4 are connected to the lower part of the side plate 102 of the container 1 by a hinge. The side plate 102 is provided with a locking mechanism 11, which includes two opposing rack blocks 111 inside the side plate 102. A gear 112 is provided between the two rack blocks 111 and meshes with it. The gear 112 is rotated by a rotating rod 113, one end of which extends to the outside of the side plate 102. Locking rods 114 are horizontally connected to both ends of the two rack blocks 111, and they pass through the side plate 102 and extend to the side plate. On the outside of 102, a telescopic spring 115 is fitted on the end of each of the two locking rods 114 away from the rack block 111. Holes suitable for the ends of the two locking rods 114 to penetrate are opened on the side walls of the box 1 on both sides of the side plate 102. The locking mechanism 11 makes it easier to take out various experimental supplies inside the box 1. When it is necessary to open, the rotating rod 113 is turned. The rotating rod 113 drives the gear 112 to rotate. The gear 112 drives the two rack blocks 111 to move relative to each other. Then, the ends of the two locking rods 114 move away from the holes opened on the side walls of the box 1, so as to open the side plate 102.

[0041] The small experimental equipment placement area 7 is located on the box cover 101. The small experimental equipment placement area 7 includes a clamping mechanism 71 and a storage box 4 72. The storage box 4 72 can hold experimental gloves, while the clamping mechanism 71 can be used to clamp and place small cylindrical experimental equipment such as pipettes.

[0042] The clamping mechanism 71 includes two opposing clamping seats 711 detachably connected to the cover plate 101. Both clamping seats 711 are provided with arc-shaped clamping blocks 712. A clamping rod 713 is horizontally connected to one clamping block 712 and passes through the clamping block 712 and the clamping seat 711. An arc-shaped clamping block 714 is also connected to the end of the clamping rod 713 at the front end of the clamping block 712. A compression spring 715 is sleeved on the clamping rod 713 between the clamping block 714 and the clamping block 712. Rubber pads 716 are provided on both the clamping block 714 and the opposing clamping block 712. When a tool is needed, the clamping rod 713 is pulled to move the clamping block 714 away from the opposing clamping block 712, increasing the distance between them. Then, the tool is placed between them and finally the clamping rod 713 is released.

[0043] The upper part of each of the two opposite side walls of the case 1 is rotatably connected with a retaining ring 12, and a shoulder strap 13 is connected between the two retaining rings 12 for easy carrying.

[0044] The outer shell of box 1 is made of a thin, light-proof material, which makes it easy to put experimental reagents that need to be protected from light inside the box 1, while the material inside the box 1 is a smooth material that is easy to clean.

[0045] A method for operating a lightweight laboratory carrying case includes the following steps:

[0046] Step 1: First, open and remove the box lid and place it. Then, turn the rotating rod. The gear drives the two rack blocks to move relative to each other. The two locking rods move away from the holes on the side wall of the box, and the side panel opens. Then, pull the top shelf. Under the action of the telescopic rod, the distance between the two shelves gradually increases. Then, rotate it to one side of the side panel. At this time, each shelf is tilted. Then, take out the reagent kits required for the experiment from the shelf. Then, take out storage box one, storage box two, and storage box three in sequence, and place each shelf, storage box one, storage box two, and storage box three one by one.

[0047] Step 2: Remove the cover plate on the dry waste bin and the nut on the liquid waste bin. Put the waste and liquid generated in the experiment into the bins respectively. When there is a lot of dry waste, press the pressure plate so that the pressure beads on both sides of the pressure plate gradually descend along the two sliding grooves until the pressure beads are stuck into the placement holes, thereby compressing the dry waste and increasing the space in the dry waste bin.

[0048] Step 3: Pour the waste generated during the experiment into the dry waste bin and the liquid waste bin respectively. After the experiment, empty the waste and put it back in its original place. Then put all the experimental equipment back into the box in the order they were taken out.

When there is a lot of dry waste, press the pressure plate so that the pressure beads on both sides of the pressure plate gradually descend along the two sliding grooves until the pressure beads are stuck into the placement holes, thereby compressing the dry waste and increasing the space in the dry waste bin. Step 3: Pour the waste generated during the experiment into the dry waste bin and the liquid waste bin respectively. After the experiment, empty the waste and put it back in its original place. Then put all the experimental equipment back into the box in the order they were taken out.
