When pulling again, the glass valve is not smooth enough, which affects the use of the electronic balance. In addition, in the current electronic balance, the balance body and the upper glass isolation plate cannot be disassembled. Since the glass isolation plate is in the use environment of chemical reagent raw materials for a long time, if it comes into contact with the reagent, it will produce stains and need to be cleaned, but the inside is not easy to clean, which reduces the efficiency of maintenance.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A chemical reagent raw material metering balance is provided with an upper protection box component group. When the current electronic balance is in use, it is necessary to repeatedly open and close the glass valve on the side. After long-term repeated use and pulling, the valve plate and the track of the glass valve are worn and blocked. When pulled again, the glass valve does not move smoothly enough, affecting the use of the electronic balance. In the correspondingly designed upper protection box component group, the technical structure of this technology, when it is necessary to open the upper protection box component group, by pulling the handle member outward, the handle member will rotate around the rotating shaft, and the magnetic attraction from the magnetic attraction block 1 and the magnetic attraction block 2 will be released, and then the operator can put the raw materials into the top of the electronic balance body. After putting in the raw materials, hold the handle and push the side glass to rotate and close on one side of the vertical plate. The vertical rods, top cover, bottom plate 2 and vertical plate are released around the side glass. The internal sealing is ensured by cooperating with the top cover and glass plate. When one side of the side glass contacts the vertical plate, the magnetic block 1 and the magnetic block 2 are magnetically attracted to lock the position of the side glass. Compared with the current push-pull glass valve, the design of the protection box component group adopts a rotating side glass for sealing protection. When used for a long time, it will not be easily blocked like the push-pull glass valve, which can increase the overall service life of the device and improve the use efficiency.

[0014] 2. This chemical reagent raw material metering balance is provided with a connecting component group. In the current electronic balance, the balance body and the upper glass isolation plate cannot be disassembled. Since the glass isolation plate is in the use environment of chemical reagent raw materials for a long time, if it comes into contact with the reagent, it will produce stains and need to be cleaned, but the inside is not easy to clean, which reduces the maintenance efficiency. In the corresponding designed connecting component group, when the glass plate and side glass parts need to be cleaned, the screws are directly removed from the bottom plate part 1 and the bottom plate part 2. After removal, the upper protection box component group and the bottom plate part 1 can be taken off the bottom plate part 2. At this time, the structure of the upper protection box component group can be cleaned more conveniently. This design can effectively improve the maintenance efficiency of the metering balance.

[0023] Four groups of vertical rods 22 are provided, and the four groups of vertical rods 22 are distributed on the four corners of the top cover plate 21 . One end of the vertical rod 22 is connected to the top cover plate 21 . Three groups of glass panels 23 are provided, and the three groups of glass panels 23 are connected to the vertical rods 22 .

[0024] The bottom of the side glass member 24 is connected to the bottom plate member 23 via a rotating shaft, and the top of the side glass member 24 is connected to the top cover plate 21 via a rotating shaft. The axis center lines of the rotating shafts at the bottom and top of the side glass member 24 are the same.

[0025] One end of the vertical plate 28 is connected to the top cover plate 21, and the other end of the vertical plate 28 is connected to the bottom plate 2 33. The surface of the side glass member 24 is connected to the magnetic block 1 26. The magnetic block 1 26 is in contact with the magnetic block 2 27. The magnetic block 2 27 is connected to the vertical plate 28. The top and bottom of the side glass member 24 are in contact with the top cover plate 21 and the bottom plate 2 33 respectively.

[0029] Working principle: When using the current electronic balance, it is necessary to repeatedly open and close the glass valve on the side. After long-term repeated use and pulling, the valve plate and the track of the glass valve will be worn and blocked. When pulling again, the glass valve is not smooth enough, affecting the use of the electronic balance. In the corresponding upper protection box component group 02, the technical structure of this technology, when it is necessary to open the upper protection box component group 02, by pulling the handle 25 outward, the handle 25 will rotate around the axis, and the magnetic attraction from the magnetic block 1 26 and the magnetic block 2 27 will be released, and then the operator can put the raw materials into the top of the electronic balance body 01. After putting the raw materials in, hold the handle 25 to push the side glass 2 4 Rotate and close on one side of the vertical plate 28, release the vertical rod column 22, the top cover 21, the bottom plate 23 and the vertical plate 28 around the side glass 24, and ensure the internal sealing by cooperating with the top cover 21 and the glass plate 23. When one side of the side glass 24 contacts the vertical plate 28, the magnetic block 1 26 and the magnetic block 27 are magnetically attracted to lock the position of the side glass 24. Compared with the current push-pull glass valve, the design of the protection box component group 02 adopts a rotating side glass 24 for sealing protection. When used for a long time, it will not be easily blocked like the push-pull glass valve, which can increase the service life of the device as a whole and improve the use efficiency. In the current electronic balance, the balance body and the upper glass isolation plate cannot be disassembled. Due to the long-term use environment of chemical reagent raw materials, if the glass isolation plate comes into contact with the reagent and produces stains, it is not easy to clean the inside when it needs to be cleaned, which reduces the maintenance efficiency. In the corresponding designed connecting component group 03, when the glass plate 23 and the side glass 24 need to be cleaned, the screw 32 is directly removed from the bottom plate 1 31 and the bottom plate 2 33. After removal, the upper protection box component group 02 and the bottom plate 1 31 can be taken off the bottom plate 2 33. At this time, the structure of the upper protection box component group 02 can be cleaned more conveniently. This design can effectively improve the maintenance efficiency of the measuring balance.
