Description

Technical Field

[0001] This utility model relates to the field of school laboratory supplies technology, and in particular to a multifunctional experimental toolbox. Background Technology

[0002] School laboratories are used for experiments in mechanics, electricity, optics, etc., such as measuring the acceleration of objects, studying current and voltage in circuits, and observing the refraction and reflection of light. Through hands-on operation of experimental instruments, students deepen their understanding of physical concepts and principles.

[0003] Currently, physics experiments require the use of numerous tools, many of which are stored in toolboxes. However, some existing toolboxes have limited functionality, failing to categorize and store instruments and tools of different types and sizes, leading to disorganization. Furthermore, the use of numerous glass instruments during experiments, due to their fragile nature, makes them susceptible to collisions, cracks, or even breakage when stored in toolboxes. Test tubes, in particular, are prone to damage during transport due to repeated collisions with rigid test tube racks. Therefore, this paper proposes a multifunctional experimental toolbox to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multifunctional experimental toolbox, which aims to improve the problems of existing technology in that it is impossible to classify and store items and to fix glass instruments in place.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multifunctional experimental toolbox includes a storage box with a lid rotatably connected to its rear end. An L-shaped partition plate is fixedly connected inside the storage box. Rotating rods rotatably connect the exterior of the L-shaped partition plate and the interior of the storage box. A placement box is rotatably connected to the top of the two adjacent sides of the two rotating rods rotatably. A rotating rod rotatably connects to the middle of the exterior of the placement box rotatably. A placement box rotatably connects to the top of the two adjacent sides of the two rotating rods rotatably. A rotating rod rotatably connects to the middle of the side of the placement box rotatably away from the L-shaped partition plate. A rotating rod rotatably connects to the bottom of the rotating rod rotatably. A rotating rod 5 is rotatably connected to the side of the placement box rotatably near the L-shaped partition plate. Multiple positioning rings are fixedly connected to the top of the L-shaped partition plate, and a fixing component for fixing experimental test tubes is provided inside the positioning rings.

[0007] As a further description of the above technical solution:

[0008] The fixing component includes multiple grooves, three of which are formed in the middle of the inside of the positioning ring. A clamping block is slidably connected inside the groove. A limit block is fixedly connected to one end of the clamping block near the L-shaped isolation plate. A spring is fixedly connected to one end of the limit block near the L-shaped isolation plate.

[0009] As a further description of the above technical solution:

[0010] A dry thermostat is installed at the bottom of the storage box. Two control buttons are installed on the front of the dry thermostat. A heat dissipation vent is opened on the front side of the storage box near the L-shaped isolation plate.

[0011] As a further description of the above technical solution:

[0012] The bottom ends of the two rotating rods are rotatably connected to the outside of the L-shaped isolation plate and the inside of the storage box, and the bottom end of the rotating rod is rotatably connected to the rear end of the placement box one on the side away from the L-shaped isolation plate.

[0013] As a further description of the above technical solution:

[0014] The bottom end of the fourth rotating rod is rotatably connected to the rear side of the inner wall of the box cover, and the bottom end of the fifth rotating rod is rotatably connected to the first placement box.

[0015] As a further description of the above technical solution:

[0016] The exterior of the placement box 1 engages with the inner wall of the storage box;

[0017] As a further description of the above technical solution:

[0018] The limiting block is externally slidably connected to the inner wall of the groove, and one end of the spring near the L-shaped isolation plate is fixedly connected to the inner wall of the groove.

[0019] As a further description of the above technical solution:

[0020] A charging port is provided at the bottom of the storage box, and the external rotatable control button is connected to the front of the storage box near the L-shaped isolation plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by opening the box lid, the box lid is connected to the second and first placement boxes via the fourth and third rotating rods. As the box lid opens, the second and first placement boxes move and fold together with the box lid. This allows the folded and unfolded placement boxes with compartments to help users better classify and organize tools and instruments, avoid confusion and collision between tools and instruments, and reduce the risk of tool damage.

[0023] 2. In this invention, the test tube is inserted into the positioning ring and the clamping block is squeezed. The clamping block, through the elastic force of a spring, holds and fixes the test tube in the middle of the positioning ring. Combined with the activation of a dry-type thermostat to control and preserve the temperature of the test tube, this fixation prevents the test tube from shaking or tipping over during the experiment, thus avoiding reagent leakage or splashing and reducing the occurrence of accidents. Simultaneously, the temperature control function ensures that the reagents inside the test tube react at a suitable temperature, preventing reagent deterioration or experimental failure due to excessively high or low temperatures.

The size of placement box 5 allows it to fit within the inner cavity of storage box 1, separated by an L-shaped partition plate 3. A rotating rod 6, a long rod, is rotatably connected to the middle of the outer surface of placement box 5. The bottom ends of the two rotating rods 6 are rotatably connected to the outer surface of the L-shaped partition plate 3 and the inner surface of storage box 1. Placement box 7 is rotatably connected to the top of the two adjacent sides of the two rotating rods 6. The rotating rods 6 connect placement box 5 and placement box 7 and provide rotational support. Placement box 7 can be used to hold small experimental supplies.

[0033] A rotating rod 8 is rotatably connected to the middle of the side of the second placement box 7 away from the L-shaped partition plate 3. The bottom end of the rotating rod 8 is rotatably connected to the rear end of the side of the first placement box 5 away from the L-shaped partition plate 3. A rotating rod 9 is rotatably connected to the bottom end of the rotating rod 8. Both the bottom end of the rotating rod 8 and the top end of the rotating rod 9 are connected to the rear outer side of the second placement box 7. The bottom end of the rotating rod 9 is rotatably connected to the rear inner wall of the lid 2. The rotating rod 9 can pull the rotating rod 8 component as the lid 2 rotates, thus unfolding the placement box.

[0034] A rotating rod 10 is rotatably connected to the side of the placement box 2 7 near the L-shaped partition plate 3. The bottom end of the rotating rod 10 is rotatably connected to the placement box 1 5. The rotating rod 10 serves to support and assist the placement box 2 7 in unfolding smoothly. Multiple positioning rings 11 are fixedly connected to the top of the L-shaped partition plate 3 to provide positions for storing test tubes and to clamp the test tubes with the fixing components. A fixing component for fixing the experimental test tubes is set in the middle of the inside of the positioning ring 11.

[0035] refer to Figure 2 , Figure 4The fixing component includes multiple grooves 12, with three grooves 12 located in the center of the positioning ring 11. The grooves 12 are equidistantly located on the inner side of the positioning ring 11. A clamping block 13, which is T-shaped, is slidably connected inside each groove 12. A limiting block 14 is fixedly connected to one end of the clamping block 13 near the L-shaped partition plate 3. The limiting block 14 is slidably connected to the inner wall of the groove 12. A spring 15 is fixedly connected to one end of the limiting block 14 near the L-shaped partition plate 3. The clamping block 13 clamps the test tube using the elastic force of the spring 15. The limiting block 14 connects the clamping block 13 and the spring 15, limiting the range of movement of the clamping block 13.

[0036] A dry-type thermostat 16 is installed at the bottom of the storage box 1. The dry-type thermostat 16 typically has a heating element, such as a metal wire or heating plate, which efficiently converts electrical energy into heat energy when powered. Two control buttons 17 are located on the front of the dry-type thermostat 16.

[0037] Working principle: When in use, the electrical components mentioned in this application can be charged by connecting to an external power source through the charging port 19. When the toolbox needs to be used to classify and store different types of tools or experimental supplies, the lid 2 can be opened and rotated to open parallel to the storage box 1. At the same time, the rotating rod 4 9 connected to the middle of the lid 2 will pull the rotating rod 3 8 as the lid 2 rotates, causing the placement box 2 7 and placement box 1 5, which are fixed by the rotating rod 3 8, to unfold along the square folding of the lid 2. At this time, since the top of the rotating rod 2 6 is fixed to the front of the outer side of the placement box 2 7 and the middle is fixed to the middle of the placement box 1 5, and the rotating rod 4 is supported and connected to the front of the placement box 1 5 through the opposite side of the storage box 1 and the L-shaped partition 3, the placement box 2 7 can be kept in a horizontal position while moving backward when the placement box 1 folds and unfolds. After unfolding, the user can place small experimental supplies in the placement box 2 7 and experimental tools in the placement box 1 5. Medicine bottles and other equipment can be placed in the inner cavity of the storage box 1 separated by the L-shaped partition 3.

[0038] The toolbox has multiple positioning rings 11 at the L-shaped isolation plate 3 position. Users can insert test tubes into the positioning rings 11 and squeeze the clamps 13. The clamps 13 clamp and fix the test tubes in the middle of the positioning rings 11 by the elastic force of the springs 15. Then, the dry thermostat 16 is activated to control the temperature and preserve the test tubes.
