Description

Technical Field

[0001] This utility model relates to the field of experimental instrument technology, and in particular to a modular temporary storage rack for chemical experimental instruments. Background Technology

[0002] Laboratory instruments are the equipment used in specific experiments in natural sciences. Commonly used instruments include test tubes, beakers, burettes, and measuring devices. These instruments are usually placed on the lab bench or stored in boxes, drawers, or cabinets. Retrieving frequently used instruments is inconvenient. Alternatively, a shelf may be placed nearby to store the instruments. However, existing chemical instrument storage racks, whether fixed, folding, or rotating, have a pre-defined layout of functional areas, making disassembly and assembly inconvenient and unable to be adjusted according to the user's specific needs and the actual space on the lab bench.

[0003] When the lab bench space is irregular or the experimental content changes, the space utilization efficiency of these storage shelves will be greatly reduced. Furthermore, the fixed layout also restricts user operating habits and cannot achieve personalized workspace arrangements. Therefore, a storage solution that can be completely freely combined and flexibly adapted is needed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a modular temporary storage rack for chemical experimental instruments. This invention not only facilitates the storage of experimental instruments but also allows for flexible adjustment of their positions to suit user operating habits, effectively improving the user's operating experience.

[0005] The technical solution of this utility model to solve the technical problem is as follows: a modular temporary storage rack for chemical experimental instruments, including a base plate, a back plate vertically provided at the top center of the base plate, a receiving groove provided at the top of the back plate, and several sets of slide rails horizontally provided on both sides of the back plate. Several sets of test tube racks, dropper racks, glass rod holders and spatula holders are slidably arranged on the slide rails, and plugs are detachably provided at both ends of the slide rails.

[0006] As an optimization, the test tube rack is plate-shaped, with one end slidably mounted in a slide rail via a pulley system. The rack has several sets of circular mounting slots, each containing a set of evenly spaced rubber springs. One end of each rubber spring connects to the side wall of the mounting slot, while the other end points towards the center of the slot. By using the circular mounting slots and rubber springs, test tubes can be accommodated, and the rubber springs can clamp them. When a test tube is inserted from the top, it pushes the rubber springs downwards, generating a continuous clamping force pointing towards the center. The larger the diameter of the test tube, the greater the expansion of the rubber springs, and the stronger the clamping force.

[0007] As an optimization, the dropper holder is plate-shaped with several sets of circular mounting slots. One end of the dropper holder is slidably mounted in a slide rail via a pulley system. This allows for the installation of a dropper, with the dropper head engaging the circular mounting slot.

[0008] As an optimization, a set of handles for the glass rod clamp is slidably mounted within the slide rail via a pulley system. The clamping end of the glass rod clamp is arc-shaped and equipped with a silicone anti-slip sleeve. The arc-shaped clamping end increases the clamping area with the glass rod; the silicone anti-slip sleeve increases friction, preventing the glass rod from slipping; the clamping position avoids the stirring end and the drainage end, preventing contact contamination; and each glass rod is suspended individually to avoid collisions with surrounding instruments.

[0009] As an optimization, a set of handles of the medicine spoon clamp is slidably mounted in the slide rail via a pulley system, and the clamping end of the medicine spoon clamp is equipped with a silicone anti-slip sleeve. By setting the silicone anti-slip sleeve, the friction can be increased to prevent the medicine spoon from slipping off. The clamping end clamps the handle of the medicine spoon, while the spoon head is suspended in the air. The suspension height can be adjusted according to the medicine spoon, so that the medicine spoon is suspended in the air and does not come into contact with other instruments.

[0010] As an optimization, absorbent cotton is installed on the base plate, with the absorbent cotton located on both sides of the back plate. By installing absorbent cotton, small amounts of waste liquid generated by dripping from the suspended instrument during the experiment can be collected, preventing contamination of the experimental platform. After the experiment, the absorbent cotton and each module can be disassembled for cleaning.

[0011] As an optimization, the base plate is also equipped with several sets of storage slots. These slots allow for the placement of beakers, test tube caps, and bottle caps.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The base plate allows for the installation of a back plate; the back plate and receiving slots support various experimental instruments, with pipettes placed within the receiving slots; sliding rails allow for the slidable installation of test tube racks, dropper racks, glass rod holders, and spatula holders. Users can adjust the positions of different modules according to their habits, achieving a personalized workspace layout. Only the necessary modules can be installed based on the actual number and type of instruments, avoiding unnecessary space occupation and maximizing space utilization for flexible experimental adaptation. The test tube racks, dropper racks, glass rod holders, and spatula holders allow users to freely combine modules as needed; end caps seal the sliding rails, preventing modules from detaching and facilitating disassembly, adjustment, and recombination of modules between different rails. This invention not only facilitates the storage of experimental instruments but also allows for flexible positioning to suit user operating habits, effectively improving the user experience.

[0017] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0018] Example 1 Figures 1 to 3 As one embodiment of this utility model, such as Figures 1 to 3 As shown, a modular temporary storage rack for chemical experimental instruments includes a base plate 1, a back plate 2 vertically positioned at the top center of the base plate 1, a cylindrical receiving groove 3 with a diameter of 50 mm and a depth of 200 mm at the top of the back plate 2, several sets of slide rails 4 horizontally positioned on both sides of the back plate 2, and several sets of test tube racks 5, dropper racks 6, glass rod holders 7 and spatula holders 8 slidably mounted on the slide rails 4 via pulley sets, and end caps 9 detachably mounted at both ends of the slide rails 4, each pulley set including four sets of pulleys 13 arranged in a matrix.

[0019] The base plate 1 allows for the installation of the back plate 2. The back plate 2 and the receiving slot 3 provide support for various experimental instruments, with the receiving slot 3 accommodating pipettes. The slide rail 4 allows for the sliding installation of test tube racks 5, dropper racks 6, glass rod holders 7, and spatula holders 8. Users can adjust the positions of different modules according to their preferences, achieving a personalized workspace layout. Only the necessary modules can be installed based on the actual number and type of instruments, avoiding unnecessary space occupation and maximizing space utilization for flexible experimental adaptation. The test tube rack 5, dropper rack 6, glass rod holders 7, and spatula holders 8 allow users to freely combine modules as needed. The plug 9 seals the slide rail 4, preventing modules from detaching and facilitating easy disassembly, adjustment, and recombination of modules between different slide rails 4.

[0020] The test tube rack 5 is plate-shaped, with one end slidably mounted in the slide rail 4 via a pulley system. The test tube rack 5 has several sets of circular mounting slots with a diameter of 35mm. Several sets of rubber springs 10 are evenly arranged within these circular mounting slots. One end of each rubber spring 10 is connected to the side wall of the circular mounting slot, while the other end points towards the center of the slot. By using the circular mounting slots and rubber springs 10, test tubes can be accommodated. The rubber springs 10 can clamp the test tubes. When a test tube is inserted from the top, it will push the rubber springs 10 downwards. The deformation of the rubber springs 10 generates a continuous clamping force pointing towards the center. The larger the diameter of the test tube, the greater the expansion of the rubber springs 10, and the stronger the clamping force.

[0021] The dropper holder 6 is plate-shaped and has several sets of circular mounting slots with a diameter of 10mm. One end of the dropper holder 6 is slidably mounted in the slide rail 4 via a pulley system. It can hold a dropper, and the head of the dropper can be inserted into the circular mounting slot.

[0022] A set of handles of the glass rod clamp 7 is slidably mounted within the slide rail 4 via a pulley system. The clamping end of the glass rod clamp 7 is arc-shaped and equipped with a silicone anti-slip sleeve with anti-slip texture. By setting the clamping end of the glass rod clamp 7 to be arc-shaped, the clamping area with the glass rod can be increased; by setting the silicone anti-slip sleeve, the friction can be increased to prevent the glass rod from slipping off; the clamping position can avoid the stirring end and the drainage end, eliminating contact contamination; each glass rod is suspended and stored individually to avoid collision with surrounding instruments.

[0023] like Figures 1 to 3 As shown, a set of handles of the medicine spoon clamp 8 is slidably mounted in the slide rail 4 via a pulley system. The clamping end of the medicine spoon clamp 8 is equipped with a silicone anti-slip sleeve with anti-slip texture. By setting the silicone anti-slip sleeve, the friction can be increased to prevent the medicine spoon from slipping off. The clamping end clamps the handle of the medicine spoon, while the spoon head is suspended in the air. The suspension height can be adjusted according to the medicine spoon, so that the medicine spoon is suspended in the air and does not come into contact with other instruments.

[0024] The base plate 1 is equipped with absorbent cotton 11, which is located on both sides of the back plate 2. By setting up the absorbent cotton 11, a small amount of waste liquid generated by the suspended instrument dripping during the experiment can be collected, avoiding contamination of the experimental table surface. After the experiment, the absorbent cotton 11 and each module can be disassembled for cleaning.

[0025] The base plate 1 is also provided with several sets of storage slots 12. By setting the storage slots 12, beakers, test tube caps and bottle caps can be placed.

[0026] In use, install the required modules into the slide rail 4 to flexibly adapt to the experimental requirements, and then install the plug 9. Before the experiment begins, place each experimental instrument into its corresponding module. When inserting a 10mm diameter test tube into the test tube rack 5, the rubber spring 10 slightly opens downwards, adhering to the outer wall of the test tube, with moderate clamping force, ensuring the test tube remains stable and does not wobble. When inserting a 20mm diameter test tube, the rubber spring 10 opens downwards, tightly adhering to the outer wall of the test tube, with a slightly increased clamping force to ensure fixation. When inserting a 30mm diameter test tube, the rubber spring 10 opens downwards to its maximum, completely adhering to the outer wall of the test tube, achieving optimal clamping elasticity and thus fixing the test tube. The dropper holder is designed to hold test tubes without damaging them; the dropper head can be directly inserted into the circular mounting slot of the dropper holder 6; the glass rod clamp 7 avoids the stirring end and the drainage end when holding glass rods, preventing contact contamination; each glass rod is suspended individually to avoid collision with surrounding instruments; the spatula clamp 8 holds the spatula by gripping the handle, suspending the spatula head in the air, and the suspension height can be adjusted according to the spatula to prevent it from contacting other instruments; during the experiment, experimental instruments are taken out as needed and returned to their original positions after use; any dripping residual liquid is collected by the absorbent cotton 11 and will not flow on the table, effectively preventing cross-contamination between different instruments. This utility model not only facilitates the storage of experimental instruments but also allows for free adjustment of positions to suit user operating habits, effectively improving the user's operating experience.
