[0002] A balance is a precision instrument for measuring the mass of an object. According to different structural principles, it can be divided into various types. An electronic balance is an important form of modern balance technology.

[0003] During the use of a balance, it may need to be used in different environments, including laboratories, factories, schools, etc. The measurement conditions in these environments may vary. The change in air flow speed caused by air flow, air conditioning or breathing air flow may affect the measurement accuracy. At the same time, when measuring some chemicals, due to their characteristics, they may be disturbed by impurities falling from the air and damage their structure. However, most traditional balances directly expose the measuring parts to the air, which not only causes the phenomenon of wind-catching, but also easily makes impurities in the air fall on the measuring parts, and its measurement accuracy cannot be guaranteed. Therefore, there is an urgent need for a balance with an air flow protection function. Summary of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] [[ID=,12]]Refer to Figure 1-8 , a balance with an air flow protection function, including a balance body 1. On one side of the upper part of the balance body 1, a mounting bracket 2 is installed. In the middle of the mounting bracket 2, a connecting frame 7 is arranged through a damping slide rail 91. One end of the connecting frame 7 is connected to a protective frame 10. On the bottom side of the inner wall of the protective frame 10, a pair of limiting slots 12 are opened. One side of the limiting slot 12 is installed with a support plate 6 through the limiting sliding of a slider 61. One end of the support plate 6 is installed with a pull plate 8. One end of the pull plate 8 passes through the mounting bracket 2 and is fitted and clamped with the connecting frame 7.

[0026] Further, the mounting bracket 2 is in an inverted "L" shape, and transparent side plates 3 are installed on both outer sides of the mounting bracket 2. The bottom end of the transparent side plate 3 is installed on the upper part of the balance body 1.

[0027] Further, a pair of card slots 21 are opened at one outer end of the mounting bracket 2, and a transparent front plate 4 is clamped and installed in the card slots 21.

[0028] Further, a feed bin 5 is installed on the upper part of the mounting bracket 2. Openings are provided on one outer side and the bottom end face of the feed bin 5. The workpiece is placed on the support plate 6 through the feed bin 5 for measurement.

[0029] Further, a pair of chutes 9 are opened in the middle of the mounting bracket 2. The chutes 9 extend upward to the inside of the feed bin 5. A through slot 11 is connected to the bottom of the chutes 9. A damping slide rail 91 is installed on the inner wall of the chutes 9, and the damping slide rail 91 is connected to the connecting frame 7.

[0030] Further, one end of the connecting frame 7 extends out of the chute 9, and a locking bolt 13 is screwed in the middle of the connecting frame 7. One end of the locking bolt 13 is in pressing contact with the outer wall of the mounting bracket 2.

[0031] Furthermore, one end of the pull plate 8 is horizontally "L"-shaped and fits closely with the side of the connecting frame 7, and the other end of the pull plate 8 is connected to the support plate 6, and sliders 61 are provided on both sides of the support plate 6. The support plate 6 is limitedly slidably installed on the bottom side of the protective frame 10.

[0032] In this embodiment, a cover can be formed by the transparent side panels 3 and the transparent front panel 4 provided at the bottom of the mounting frame to protect the space above the balance body 1, which can effectively protect against external airflow and impurities. During the actual measurement process, the measuring piece is placed in the feed chamber 5 and supported by the support plate 6, and then the connecting frame 7 is manually pressed down to make the support plate 6 move downward until it is above the balance measuring disk. Then, when the position of the support plate 6 is matched with the position of the through slot 11 at the bottom of the mounting frame 2, the pull plate 8 connected to one side of the support plate 6 is pulled so that the support plate 6 is pulled out of the outside of the mounting frame 2 through the through slot 11. Relatively speaking, the measuring piece is placed on the balance measuring disk.

[0033] In actual use, the support plate 6 and the protective frame 10 form a drawer-like structure, and the pull plate 8 is used to realize the pulling and pulling function of the support plate 6.

[0034] In actual use, when the through slot 11 provided at the bottom of the mounting frame 2 coincides with the position of the supporting plate 6 , the supporting plate 6 can be pulled out of the through slot 11 by pulling the pulling plate 8 .

[0035] In actual use, a cover is still provided on one side of the feed cabin 5 for protection when not in use.

[0036] In actual use, when the balance is not in use, the support plate 6 is fixed as a whole in the feed chamber 5, that is, at the top of the mounting frame 2, by tightening the locking bolt 13.

[0037] Among them, in actual use, the connecting frame 7 realizes the lifting operation through the slide groove 9 and the damping slide rail 91, wherein the damping slide rail 91 is specifically a slide rail provided with a damping part, which has a certain sliding damping force during the sliding process. Its principle is the same as that of the pull-out cabinet of the wardrobe, and no further details will be given here.

[0038] In the present invention, the protective function is achieved by cooperating with the transparent side panels 3 and the transparent front panel 4 provided at the bottom of the mounting frame 2, which can effectively protect against external airflow and dust. At the same time, during the measurement process, the measuring piece is placed through the feed cabin 5 and the measuring piece is placed above the balance in conjunction with the connecting frame 7 and the support plate 6. The measuring piece is placed on the balance for measurement by pulling out the support plate 8. At the same time, the transparent front panel 3 can also be pulled out and disassembled to place the measuring piece, which can effectively maintain the reliability and accuracy of the balance under experimental conditions.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
