Description

Technical Field

[0001] The utility model belongs to the field of experimental instruments, relates to the field of experimental measuring cylinders, and specifically relates to a pharmaceutical experimental measuring cylinder. Background Art

[0002] When conducting pharmaceutical experiments, graduated cylinders are used to measure liquid volumes and prepare solutions or solvents. Currently, graduated cylinders are typically made of glass. Glass cylinders offer excellent optical transparency, allowing for clear observation of liquid volume. They are also less susceptible to temperature fluctuations and can be used over a wide range without affecting measurement accuracy. Glass cylinders also possess excellent chemical resistance, allowing them to be used in a variety of chemical environments without reacting or dissolving, ensuring stability. Therefore, glass cylinders are widely used in laboratories.

[0003] Glass graduated cylinders also have the disadvantage of being fragile. In most cases, the bottom of the cylinder will often collide with the supporting surface, causing damage to the cylinder, so they must be handled with caution. When adding liquid to the cylinder, an incorrect estimate of the initial liquid volume in the cylinder can cause the added liquid to exceed the cylinder's capacity, causing the liquid to overflow. Alternatively, the liquid in the cylinder can be affected by temperature changes, causing the volume to change, causing it to overflow. Liquid that overflows the cylinder can contaminate the laboratory environment, the supporting surface, other laboratory equipment, or experimental materials. If the spilled liquid is a hazardous chemical, it may pose a threat to the safety of laboratory personnel, including chemical burns and poisoning. Therefore, when liquid overflows from the cylinder, it needs to be disposed of promptly. Utility Model Content

[0004] The utility model provides a pharmaceutical laboratory measuring cylinder to solve the technical problem that the bottom of the measuring cylinder is easily damaged and the liquid overflows, thereby posing a risk. A rubber pad is installed on the bottom of the cylinder to improve safety protection. A drainage bottle is installed on the rubber pad. The drainage tube is extended into the measuring cylinder, and the water absorption strip is used to drain and collect the liquid exceeding the capacity of the measuring cylinder, thereby preventing liquid overflow and facilitating its timely disposal, thereby ensuring safety in use.

[0005] The technical solution adopted by the utility model is as follows: providing a pharmaceutical laboratory measuring cylinder, comprising a cylinder body, a cylinder bottom arranged at the bottom of the cylinder body, and a pouring spout arranged at the top of the cylinder body, the cylinder body is provided with scale lines, the diameter of the cylinder bottom is larger than the diameter of the cylinder body, the outer surface of the cylinder bottom is covered with a rubber pad, a transparent drainage bottle is arranged on the top of the rubber pad, a drainage tube is connected to the top of the drainage bottle, the drainage tube is located at one side of the pouring spout, the top of the drainage tube is higher than the top of the cylinder body, the top of the drainage tube is bent upwards toward the cylinder body and then bent downwards into the cylinder body, so that the height of the tube spout is lower than the pouring spout, and the outer tube wall of the drainage tube is in contact with and fits the inner wall of the cylinder body; the drainage tube is filled with a water absorption strip, and the two ends of the water absorption strip respectively pass through the two ends of the drainage tube.

[0006] The rubber pad at the bottom of the measuring cylinder can avoid damage from bumps, and the rubber pad increases the friction and grip of the measuring cylinder, ensuring the stability of the placement of the measuring cylinder. The elbow of the drainage tube is placed in the cylinder body of the measuring cylinder and contacts and fits with the inner wall of the cylinder, thereby reducing the space occupied by the measuring cylinder, and the drainage tube is located on one side of the pouring port to avoid interference with the use of the pouring port, ensuring flexibility of use. The other end of the drainage tube is connected to the drainage bottle on the top of the rubber pad to support the drainage tube and ensure reliability of use. The nozzle position of the drainage tube in the measuring cylinder is lower than the position of the pouring port, and the water absorption strip inserted in the drainage tube passes through the drainage tube. As liquid is added to the measuring cylinder, the liquid contacts the water absorption strip, is absorbed by the water absorption strip and is introduced into the drainage bottle along the drainage tube, thereby avoiding liquid overflow from the measuring cylinder, facilitating timely disposal, and ensuring safety of use.

[0007] To further optimize this technical solution, the drainage bottle includes an open bottle body, a cup seat is mounted on the bottom of the bottle body, the cup seat is detachably connected to the rubber pad by means of a connector, and a bottle cap is sealed on the top of the bottle body, and the bottle cap is sealed and connected to the drainage tube.

[0008] The bottle body is assembled through the cup holder and rubber pad at the bottom to support the bottle body. The bottle cap is sealed on the top of the bottle body and is connected to the drainage tube with the help of the bottle cap. The disassembly and assembly of the bottle cap and the bottle body facilitates the cleaning of the drainage bottle and ensures flexibility of use.

[0009] To further optimize the technical solution, the top of the bottle cap is connected and equipped with a butt joint tube, the inner tube wall of the butt joint tube is pasted with an annular gasket, and the inner ring wall of the gasket is sealed and plugged with the outer tube wall of the drainage tube.

[0010] The bottle cap is connected to the drainage tube by means of a butt joint, which makes it easy to assemble and disassemble. An annular gasket is pasted on the inner wall of the butt joint, and the inner ring wall of the gasket is sealed and plugged into the outer wall of the drainage tube, ensuring the sealing of the butt joint between the butt joint and the drainage tube and ensuring reliability in use.

[0011] To further optimize the technical solution, the connecting piece includes a slot provided on the top of the rubber pad and a plug provided on the bottom of the cup holder, and the plug is interference-fitted with the slot.

[0012] After the plug arranged at the bottom of the cup holder is interference-fitted with the slot opened at the top of the rubber pad, the cup holder support is fixed on the rubber pad to support the drainage bottle. The plugging of the plug and the slot makes the disassembly operation of the cup holder simple and smooth.

[0013] To further optimize the technical solution, a groove is provided on the top of the rubber pad, the groove matches the shape of the bottom of the cylinder, and the bottom of the cylinder is sleeved with the groove.

[0014] The rubber pad is provided with a groove which matches the shape of the cylinder bottom of the measuring cylinder so that the rubber pad can be sleeved on the cylinder bottom and the firmness of the sleeve can be ensured.

[0015] To further optimize this technical solution, the water-absorbing strip is a sponge strip.

[0016] The porous structure of the sponge strip creates a large number of tiny pores inside it, which produces strong capillary action and surface tension, allowing water to be quickly absorbed and dispersed into the sponge, quickly absorbing and transporting the liquid. The sponge strip is cheap and easy to obtain, reducing the cost of use.

[0017] To further optimize the technical solution, the sponge strip is coaxially provided with a through groove, and a soft shaft is inserted into the through groove.

[0018] The sponge strip is supported by a through groove and a flexible shaft inserted into the through groove, which makes it easy to push the sponge strip into the drainage tube. The flexible shaft can be deformed to adapt to the shape of the drainage tube, thereby improving the efficiency of inserting and removing the sponge strip.

[0019] To further optimize the technical solution, the flexible shaft includes a support spring, a sleeve is provided on the outside of the support spring, and the sleeve is plugged into the through groove on the sponge strip.

[0020] After the sleeve wraps the support spring, it is plugged into the through groove on the sponge strip. The support spring supports the sponge strip, making it convenient to push it into the drainage tube. The support spring can bend and deform to drive the sponge strip to bend and adapt to the shape of the drainage tube. It has a simple structure and low cost.

[0021] The beneficial effects of the present invention are:

[0022] 1. The rubber pad is fitted on the bottom of the cylinder through the groove, so that the rubber pad is wrapped on the bottom of the cylinder to protect the bottom of the cylinder and prevent it from being damaged by bumps. The rubber pad also increases the friction between the bottom of the cylinder and the supporting surface, and improves the grip of the cylinder to ensure stability in use. At the same time, the rubber pad has the effect of shock absorption and noise reduction, thereby protecting the cylinder and reducing noise, and is flexible to use.

[0023] 2. A drainage bottle is added to the rubber pad, and a drainage tube is connected to the drainage bottle. The drainage tube extends from the bottle mouth of the measuring cylinder into the measuring cylinder, and the height of the drainage tube mouth is lower than the height of the pouring mouth of the measuring cylinder. When the liquid in the measuring cylinder is excessively added, the water absorption strip in the drainage tube absorbs the liquid and transfers it to the drainage bottle through the drainage tube, thereby preventing the liquid from overflowing from the measuring cylinder and facilitating its timely disposal, thereby ensuring safety in use;

[0024] 3. The sponge strip in the drainage tube is supported by a rotating shaft. The rotating shaft is composed of a sleeve wrapped with a support spring. After being plugged into the through slot on the sponge strip, the rotating shaft supports the sponge strip so that the sponge strip can be pushed into the drainage tube. The support spring can be bent and deformed to drive the sponge strip to deform, so that the sponge strip can adapt to the shape of the drainage tube and ensure flexibility in use.

[0025] 4. When the drainage tube is placed in the body of the measuring cylinder, its outer tube wall contacts and fits with the inner wall of the cylinder, thereby reducing the encroachment of the drainage tube on the cylinder space. The drainage tube is located on the side of the pouring port to avoid interfering with the use of the pouring port, ensuring smooth use. The inner wall of the cylinder supports the drainage tube to ensure the firmness of the drainage tube layout, making it safer and more reliable to use. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the rubber pad 5 increases the contact friction between the cylinder bottom 2 and the supporting surface, and provides additional grip to prevent the measuring cylinder from sliding on the supporting surface, thereby improving the stability of use. In addition, the rubber pad 5 also has the effects of shock absorption and noise reduction, can absorb impact and vibration, protect the measuring cylinder and reduce noise;

[0036] Please see the attached Figure 1-4 , a transparent drainage bottle 6 is provided on the top of the rubber pad 5, and a drainage tube 7 is provided on the top of the drainage bottle 6. The drainage tube 7 is located on one side of the pouring port 3, and the top of the drainage tube 7 is higher than the top of the barrel 1. The top of the drainage tube 7 is bent upwards toward the barrel 1 and then bent downwards into the barrel 1, and the height of the tube mouth is lower than the pouring port 3, and the outer tube wall of the drainage tube 7 is in contact with the inner wall of the barrel 1, thereby reducing the occupied area of the drainage tube 7 in the barrel 1 and not interfering with the use of the pouring port 3, ensuring smooth use. The drainage bottle 6 includes an open bottle body 601, and a cup holder 602 is mounted on the bottom of the bottle body 601. The cup holder 602 is detachably connected to the rubber pad 5 by means of a connector. The connector can be a slot 501 opened on the top of the rubber pad 5 and a plug 6021 provided at the bottom of the cup holder 602. After the socket and the slot 501 are interference-fitted, the cup holder 602 is fixed on the rubber pad 5. The plugging of the plug 6021 and the slot 501 facilitates the disassembly and assembly of the cup holder 602, thereby improving the flexibility of use.

[0037] Please see the attached Figure 2 , Attachment Figure 4 The top of the bottle body 601 is sealed and assembled with a bottle cap 603, and the top of the bottle cap 603 is connected and assembled with a docking tube 604. The inner tube wall of the docking tube 604 is pasted with an annular gasket 6041, and the inner ring wall of the gasket 6041 is sealed and plugged with the outer tube wall of the drainage tube 7, so that the docking tube 604 is connected with the drainage bottle 6. The drainage tube 7 is filled with a water absorption strip 8, and the two ends of the water absorption strip 8 respectively pass through the two ends of the drainage tube 7. After the water absorption strip 8 penetrates into the barrel body 1, when the barrel body 1 is filled with liquid, the liquid contacts the water absorption strip 8 and is introduced into the drainage bottle 6 along the drainage tube 7 by the water absorption strip 8, thereby preventing the liquid from overflowing from the measuring cylinder and ensuring safety in use.

[0038] Please see the attached Figure 5-7The water-absorbing strip 8 can be made of a sponge strip 801, and a through groove 8011 is coaxially opened on the sponge strip 801. A soft shaft 9 is inserted into the through groove 8011. The soft shaft 9 supports the sponge strip 801 so that it can be pushed into the drainage tube 7 smoothly and can be easily bent to adapt to the shape of the drainage tube 7 to ensure flexibility in use.

It is flexible in use, has a simple structure, and has a low manufacturing cost.

[0039] The working principle of the pharmaceutical laboratory measuring cylinder is as follows: the rubber pad 5 is fitted with the cylinder bottom 2 through the groove 502, so that the rubber pad 5 is wrapped on the cylinder bottom 2 to protect the cylinder bottom 2 and prevent it from being damaged by bumps. The rubber pad 5 also increases the friction and grip of the measuring cylinder when it is placed, ensuring stability in use. At the same time, the rubber pad 5 also has shock absorption and noise reduction effects. When the measuring cylinder is in use, the drainage bottle 6 is plugged into the slot 501 on the rubber pad 5 through the cup holder 602 to fix the drainage bottle 6 on the rubber pad 5, and then the drainage tube 7 is connected to the drainage bottle 6, and the elbow at the top of the drainage tube 7 is placed in the cylinder body 1 of the measuring cylinder and in contact with the inner wall of the cylinder body 1, thereby reducing the occupied area in the cylinder body 1 and reducing interference with the use of the measuring cylinder. When adding liquid to the measuring cylinder, if excessive liquid is added, the height of the nozzle of the drainage tube 7 in the measuring cylinder is lower than the height of the pouring port 3, and the sponge strip 801 in the drainage tube 7 passes through the nozzle, first contacts with the liquid, absorbs the liquid and transfers it from the drainage tube 7 to the drainage bottle 6, thereby avoiding liquid overflow and taking timely measures to ensure the safety of the measuring cylinder. After use, the measuring cylinder is removed from the drainage bottle 6 and the drainage tube 7, and the body 601 and the cap 603 of the drainage bottle 6 are disassembled to clean the interior of the drainage bottle 6. After the drainage tube 7 is disassembled from the drainage bottle 6, the sponge strip 801 is pulled out of the drainage tube 7 to clean the drainage tube 7. After the sponge strip 801 is cleaned, it is pushed into the drainage tube 7 for reuse. The sponge strip 801 is wrapped in a sleeve 901 supported by a support spring 902. The support spring 902 facilitates the smooth pushing of the sponge strip 801 into the drainage tube 7 and facilitates deformation and bending to adapt to the shape of the drainage tube 7, making the operation smooth and the use flexible.
