Description

Technical Field

[0001] This utility model belongs to the field of drug testing technology, specifically, it relates to a high-precision electronic analytical balance for drug testing. Background Technology

[0002] In modern drug development, drug quality control, and various drug experiment scenarios, high-precision electronic analytical balances are one of the core devices for conducting precise drug experiments and controlling drug quality. From the precise proportioning of active ingredients in the process of innovative drug development to the strict measurement of raw and auxiliary materials in the drug production process, their weighing accuracy is related to the efficacy, safety, and even the stable development of the entire pharmaceutical industry.

[0003] Drug testing involves a wide variety of materials, including large drug samples with coarse particles, loose texture, or irregular shapes. While conventional electronic analytical balances continue to advance in precision design, the functional limitations of their windproof covers are gradually becoming an obstacle to high-precision weighing. Traditional windproof covers and balance pans are simply fitted together, lacking precise guidance and a stable protection mechanism. When staff place larger drugs on the weighing pan and manually close the windproof cover, the unavoidable slight tremors of the hand are amplified in this scenario. This often results in the windproof cover inadvertently touching the drug. Once the drug is subjected to force, it will shift on the smooth surface of the weighing pan. For weighing drugs with milligram or even microgram precision requirements, even a small displacement can cause the reading deviation to skyrocket, disrupting the originally accurate measurement process.

[0004] Furthermore, the laboratory space is compact and operations are frequent. When staff are focused on preparing medicines and recording data, their bodies and arms are prone to accidentally bumping into the wind shield. Conventional wind shields are not very stable. After being hit by external force, they not only change their own position, but may also knock over the carefully placed and valuable medicines on the weighing pan, causing material waste, interruption of experiments, and even repeated weighing to accumulate errors and affect the validity of the entire batch of experimental data, resulting in significant economic losses and wasted time. In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art and provide a high-precision electronic analytical balance for drug experiments that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a high-precision electronic analytical balance for drug experiments, including a balance body, on which a weighing pan is installed, and further including: four limiting posts, fixedly connected to the balance body and arranged in a rectangle around the outside of the weighing pan; a windproof cover, fitted over the outside of the four limiting posts; the windproof cover includes a transparent shell, an upper mounting frame, a lower mounting frame, and a transparent top plate, the transparent shell being fixedly installed between the upper and lower mounting frames, and the transparent top plate being fixedly installed on the upper mounting frame.

[0007] To facilitate operation without requiring staff to constantly lift the windproof cover, a limiting magnetic block is fixedly connected to the top of the limiting post, and a second magnetic block that magnetically attracts the limiting magnetic block is fixedly connected to the lower mounting frame near the limiting post. The second magnetic block slides and adheres to the limiting post.

[0008] To ensure a good seal between the lower mounting frame and the balance body, a rubber gasket is fixedly connected to the bottom of the lower mounting frame.

[0009] To further improve the stability and windproof effect of the windproof cover, a first magnetic block that is magnetically attracted to the limiting magnetic block is embedded in the upper mounting frame near the limiting post.

[0010] To prevent staff from leaving fingerprints on the windproof cover when moving it, a lifting handle is fixedly connected to both sides of the transparent shell and the top of the transparent top plate.

[0011] To facilitate height adjustment of the analytical balance, adjustable feet are provided at the four corners of the bottom of the balance body. Threaded posts are threaded onto the adjustable feet and fixedly connected to the balance body.

[0012] To further improve the stability of the analytical balance when placed on the platform, the bottom of the adjusting feet is fixedly connected with an anti-slip pad.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention, through the setting of four limiting columns, can guide the windproof cover when it is placed on the outside of the weighing pan, so as to prevent the windproof cover from hitting the medicine due to hand tremors when weighing large medicines, causing the medicine to shift and affecting the weighing accuracy. At the same time, when the staff accidentally touches the windproof cover, it can prevent the windproof cover from shifting and hitting the medicine, causing the windproof cover and medicine to tip over and cause economic losses, thus effectively improving the stability of the windproof cover.

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] Example 1:

[0024] Reference Figures 1-5 A high-precision electronic analytical balance for drug testing includes a balance body 1, on which a weighing pan 104 is mounted. It also includes four limiting posts 3, fixedly connected to the balance body 1 and arranged in a rectangular shape around the weighing pan 104; and a windproof cover 2, fitted over the four limiting posts 3. The windproof cover 2 includes a transparent shell 201, an upper mounting frame 202, a lower mounting frame 203, and a transparent top plate 204. The transparent shell 201 is fixedly installed between the upper mounting frame 202 and the lower mounting frame 203, and the transparent top plate 204 is fixedly installed on the upper mounting frame 202.

[0025] Both the transparent shell 201 and the transparent top plate 204 can be made of highly transparent materials such as glass.

[0026] When using this analytical balance to weigh medicines, the staff first takes the analytical balance and places it on the platform. Then, the staff powers on the analytical balance and turns it to zero. The staff then opens the windproof cover 2 upwards, so that the windproof cover 2 is removed from the balance body 1. The staff then places the medicine on the weighing pan 104. The staff then moves the windproof cover 2 downwards along the four limit posts 3 until the windproof cover 2 sits on the balance body 1. The staff can then know the specific weight of the medicine on the weighing pan 104 by reading the scale on the balance body 1.

[0027] By setting four limiting posts 3, when the windproof cover 2 is placed on the outside of the weighing pan 104, it can guide the windproof cover 2, preventing the windproof cover 2 from hitting the medicine due to hand tremors when weighing larger medicines, thus avoiding displacement of the medicine and affecting the accuracy of weighing. At the same time, if the staff accidentally touches the windproof cover 2, it can prevent the windproof cover 2 from shifting and hitting the medicine, causing the windproof cover 2 and the medicine to tip over and cause economic losses, effectively improving the stability of the windproof cover 2.

[0028] Example 2:

[0029] Reference Figures 1-5 The high-precision electronic analytical balance for drug experiments is basically the same as in Example 1, but with a further improvement: a limiting magnetic block 301 is fixedly connected to the top of the limiting column 3, and a second magnetic block 2031, which is magnetically attracted to the limiting magnetic block 301, is fixedly connected to the lower mounting frame 203 near the limiting column 3. The second magnetic block 2031 slides and adheres to the limiting column 3. Through the cooperation of the limiting magnetic block 301 and the second magnetic block 2031, when it is necessary to open the windproof cover 2 to place the drug onto the weighing pan 104 for testing... During weighing, the windproof cover 2 can be moved upwards. When the second magnetic block 2031 comes into contact with the limiting magnetic block 301, the windproof cover 2 will be fixed in place by the mutual magnetic attraction between the limiting magnetic block 301 and the second magnetic block 2031. Then, the staff can place the medicine on the weighing pan 104 and then close the windproof cover 2 to carry out the weighing process. There is no need for the staff to lift the windproof cover 2 all the time or to directly remove the windproof cover 2, which would affect the weighing efficiency.

[0030] A rubber pad 206 is fixedly connected to the bottom of the lower mounting frame 203. The rubber pad 206 can provide a good sealing effect between the lower mounting frame 203 and the balance body 1, further reducing the impact of the external environment on the balance accuracy.

[0031] A first magnetic block 2021 is embedded in the upper mounting frame 202 near the limiting post 3, which is magnetically attracted to the limiting magnetic block 301. With the setting of the first magnetic block 2021, when the windproof cover 2 is covered on the balance body 1, the first magnetic block 2021 will attract the limiting magnetic block 301. This not only improves the stability of the windproof cover 2 on the balance body 1, but also applies a downward squeezing force to the rubber pad 206, thereby further improving the sealing performance of the rubber pad 206 between the lower mounting frame 203 and the balance body 1.

[0032] Lifting handles 205 are fixedly connected to both sides of the transparent shell 201 and the top of the transparent top plate 204. With the lifting handles 205, the staff can move the windproof cover 2 smoothly up and down without touching it with their hands, thus avoiding leaving fingerprints on the windproof cover 2 and affecting the staff's ability to inspect the items inside the windproof cover 2.

[0033] Example 3:

[0034] Reference Figures 1-5 The high-precision electronic analytical balance for drug experiments is basically the same as in Example 2, but with a further improvement: each of the four corners at the bottom of the balance body 1 is provided with an adjusting foot 102, and a threaded post 101 is threadedly connected to the adjusting foot 102. The threaded post 101 is fixedly connected to the balance body 1. When it is necessary to adjust the height of the analytical balance, the four adjusting feet 102 can be rotated in sequence, and then the height of the analytical balance can be flexibly adjusted with the help of the threaded post 101. Thus, the height can be adjusted according to the placement environment to ensure the stability of the placement and the accuracy of the counting.

[0035] An anti-slip pad 103 is fixedly connected to the bottom of the adjusting foot 102. The anti-slip pad 103 increases the friction between the adjusting foot 102 and the platform, thereby improving the stability of the analytical balance when placed on the platform.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
