[0001] The utility model relates to the technical field of specific gravity bottles, in particular to a specific gravity bottle for drug detection. Background Art
[0002] A pycnometer is a device that can accurately measure the volume of a glass or metal container. It can measure the density of a liquid and the volume defined by its volume by simple weighing. The known volume of the pycnometer can be used to measure the density of powders, liquids, and particles.
[0003] The pycnometer has a simple structure and is easy to operate. When testing liquid, it is necessary to expel the bubbles in the liquid to accurately detect the density of the pycnometer. This is usually done by shaking, tapping with a glass rod, etc., but the efficiency is relatively low and attention must be paid to the strength to avoid damage to the bottle body. In view of this situation, the utility model proposes a new solution. Utility Model Content

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] It should be noted that before use, check whether the pycnometer is intact and all parts are installed correctly. When sampling, ensure that the depth of the pipette 13 inserted into the liquid is sufficient to avoid inhaling air or impurities on the liquid surface. When knocking on the bottle body 1 to remove bubbles, pay attention to the moderate force of the knocking to avoid damaging the bottle body 1 or the knocking piece. When measuring the liquid density, ensure that the collecting tube 3 is clean and dry to avoid errors.
[0027] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: the specific gravity bottle is composed of a bottle body 1, a knocking piece, a sampling piece and a branch pipe 14 and other parts.
[0028] The bottle body 1 is the main part of the pycnometer, which is usually made of transparent material and can visually observe the condition of the liquid sample. A knocking piece is arranged under the bottle body 1. When performing density measurement, bubbles in the liquid will interfere with the result and cause inaccurate measurement. The knocking piece can effectively expel the bubbles in the liquid by knocking on the ridge 11 at the bottom of the bottle body 1. The design of the ridge 11 makes the knocking more frequent and intensive, thereby improving the efficiency of bubble removal. The presence of the ridge 11 enables the knocking piece to better transmit force when knocking, thereby effectively removing bubbles from the liquid. This design makes the operation simpler and more efficient. The pycnometer also includes other parts such as a sampling piece and a branch pipe 14. The sampling piece is used to obtain an appropriate amount of sample from the liquid to be tested, and the branch pipe 14 is used to introduce the liquid into the collection for subsequent operations. A depression 101 is arranged on the surface of the bottle body 1 to facilitate hand-holding of the pycnometer.
[0029] like Figure 1-Figure 3 As shown, the striking member is composed of multiple parts such as an insertion rod 701, a carrier 7 and a touch rod 8.
[0030] The insertion rod 701 slides in the connecting block 10. This structure not only allows the insertion rod 701 to move freely in the connecting block 10, but also makes it easy to adjust the position of the knocking piece. A plurality of touch rods 8 are arranged on the side of the carrier 7 facing the bottle body 1. These touch rods 8 are arranged neatly and in moderate number, which not only ensures sufficient impact force but also avoids excessive friction and loss. The touch rod 8 is made of a plastic material that is both tough and elastic and has sufficient strength. A ball block 9 is fixed at the end of the touch rod 8. This design enables the ball block 9 to frequently and closely contact the convex ridge 11 when the knocking piece knocks on the convex ridge 11. The surface of the bottle body 1 is connected to an arm rod 5 through two symmetrically arranged hinge blocks 4. The two arm rods 5 are connected by a cross bar 6, and the knocking piece is located in the middle of the cross bar 6.
[0031] like Figure 3 As shown, the sampling piece is used for sampling and sealing the bottle body 1, and it includes a hollow block 12 and a straw 13. The hollow block 12 is equipped with a straw 13 connected to the inside of the hollow block 12. The hollow block 12 is made of a soft material of rubber or silicone and is used to block the bottle mouth 2 of the bottle body 1. A gap is set between the end of the straw 13 and the inner wall of the bottom of the bottle body 1. In this way, when sampling is needed, it is only necessary to insert the straw 13 into the liquid and press the hollow block 12 to suck the liquid sample into the hollow block 12, so that a small amount of liquid in the bottle can be sampled.
[0032] like Figure 3 and Figure 4 As shown, the connection between the branch tube 14 and the inner wall of the bottle mouth 2 is processed by a chamfering process, and the collecting tube 3 is inserted at the end of the branch tube 14. The branch tube 14 is used to guide the liquid sample from the specific gravity bottle into the collecting tube 3 for subsequent drug testing. A gasket cover 302 is installed at one end of the sample tube 301, and the branch tube 14 is inserted into the gasket cover 302. A pressure relief port 303 is also provided on the gasket cover 302. The pressure relief port 303 can make the pressure inside and outside the sample tube 301 the same, so that the liquid can enter the sample tube 301 conveniently.
[0033] When using the pycnometer, the bubbles in the liquid are removed by knocking the ridge 11 with a knocking piece, and the density of the liquid can be calculated by measuring the volume and mass of the liquid sample in the collecting tube 3. The branch tube 14 is connected to the collecting tube 3, and the liquid sample is led out from the pycnometer into the collecting tube 3.
[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
