Description

Technical Field

[0001] The utility model relates to the field of electronic balances, in particular to a high-precision micro electronic balance. Background Art

[0002] An electronic balance is a high-precision weighing device that uses electromagnetic force to balance the gravity of the object to be measured, thereby achieving the measurement of mass. Compared with traditional mechanical balances, electronic balances have higher accuracy, faster response speed, and more convenient operation characteristics.

[0003] Chinese Utility Model Patent CN221571657U discloses an electronic balance with an anti-pollution function. When this electronic balance is in use, a feed hopper is used to guide the material to be weighed onto the electronic balance body. After weighing is completed, a feeding mechanism can quickly discharge the weighed material, thereby achieving the purpose of efficient weighing, avoiding the problem of cumbersome manual material collection operations, and improving the overall usability; in the actual use process, due to the high weighing accuracy of the electronic balance, it is easily affected by external factors, especially vibrations, resulting in changes in the reading, and further affecting the weighing accuracy. For this electronic balance, when the material is directly dropped from the feed hopper onto the balance body, it will generate an impact. At the same time, the feeding mechanism will also generate vibrations when horizontally pushing the material out, which may all cause impacts on the electronic balance body, thereby affecting its weighing stability and causing changes in the final reading, resulting in inaccurate measurement results. Summary of the Utility Model

[0004] In order to overcome the above-mentioned disadvantages of the prior art, the utility model provides a high-precision micro electronic balance with a buffer and shock absorption function.

[0005] The technical solution is: a high-precision micro electronic balance, including a balance body and a weighing pan detachably arranged on the balance body; it also includes an outer cover rotatably connected to the balance body, a hollow frame is installed at the rear of the outer cover, and a fan is installed in the hollow frame; it further includes a support frame fixedly arranged at the rear of the balance body, a buffer pad capable of contacting the outer cover is arranged at the top of the support frame; it also includes a gasket arranged around the edge of the upper surface of the balance body and capable of connecting with the end of the outer cover.

[0006] Furthermore, the gasket is detachably arranged on the balance body, and a pull strap is arranged on the gasket.

[0007] Furthermore, a cover plate with a buckle strap is rotatably arranged at the rear of the hollow frame.

[0008] Furthermore, a buckle plate capable of connecting with the cover plate and limiting the cover plate is rotatably arranged at the top of the hollow frame.

[0009] Furthermore, handles are provided on both the outer cover and the balance main body.

[0010] Furthermore, rubber pads are provided at the bottom of the balance main body.

[0011] The beneficial effects are as follows: Through the buffer cushion plate provided at the top of the support frame, when the outer cover is opened, the outer cover can be supported and buffered, reducing the vibration generated when the outer cover is opened, and thus reducing the impact on the balance main body. The design of the gasket can not only buffer and shock-absorb the outer cover when it is closed, but also enhance the sealing degree between the outer cover and the balance main body, enabling the weighing step to be completed in a relatively enclosed environment, reducing the influence of external factors on weighing, and the pull belt on the gasket can also facilitate its replacement; by installing a fan in the hollow frame, when weighing items with pungent odors, after weighing is completed, the ventilation efficiency can be increased, promoting the rapid dissipation of the pungent odor, and a cover plate and a buckle plate are provided at the rear side of the hollow frame to close the hollow frame when the fan is not in use, thereby ensuring the tightness of the weighing process; the handles provided on the outer cover and the balance main body facilitate their handling and transfer; the rubber pad at the bottom of the balance main body provides better grip, reduces the impact of vibration on measurement, and also protects the placement surface from damage.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] like Figure 1 As shown, the embodiment of the utility model provides a high-precision micro electronic balance, including a balance body 1 and a weighing pan 11 detachably arranged on the balance body 1. When the material is placed on the weighing pan 11, the weight of the material can be obtained through the reading on the display of the balance body 1. An outer cover 2 is rotatably arranged on the rear side of the balance body 1. After placing the material, the outer cover 2 is turned over to cover the weighing pan 11, so that the weighing is completed in a relatively closed environment, avoiding the influence of air flow on the weighing of the balance body 1, thereby improving the stability and accuracy of the measurement, and handles are arranged on the outer cover 2 and the balance body 1, which can facilitate the user to open and close the outer cover 2, and the handle of the balance body 1 can also improve the convenience of the entire electronic balance during transfer and transportation. A rubber foot pad is arranged at the bottom of the balance body 1, which can provide it with good grip when placed flat, thereby enhancing the stability of the entire electronic balance during use.

[0019] like Figure 2 As shown, in the embodiment of the utility model, a support frame 3 is fixedly provided on the rear side of the balance body 1, and a buffer pad 31 made of a flexible material is provided on the top of the support frame 3. After the outer cover 2 is opened, the buffer pad 31 can support it and provide a buffering and shock-absorbing effect at the same time. A circle of rubber gasket 4 is bonded to the upper surface of the balance body 1 around the weighing pan 11, and when the outer cover 2 is closed, its end just connects with the gasket 4, and the rubber gasket 4 can also buffer and shock-absorb the outer cover 2, and then when the outer cover 2 is opened and covered, it can provide good shock-absorbing protection for the entire balance body 1, and reduce the influence of external factors such as vibration on its weighing results. Figure 2 As shown, a drawstring 41 is also provided at the front of the gasket 4, and the drawstring 41 can be used to facilitate the user to tear off the gasket 4 for replacement.

[0020] like Figure 3 and Figure 4 As shown, in the embodiment of the utility model, a hollow frame 5 is also installed on the rear side of the outer cover 2, three electric fans 51 are installed in the hollow frame 5, and a cover plate 7 with a buckle belt 71 is rotatably provided at the bottom of the rear side of the hollow frame 5, and a buckle plate 6 is rotatably provided at the top of the hollow frame 5. Initially, the cover plate 7 closes the rear side wall of the hollow frame 5, and the buckle plate 6 is connected to the cover plate 7 and prevents the cover plate 7 from flipping open. After the weighing of the material with a pungent odor is completed, the buckle plate 6 can be flipped upwards first to disengage it from the cover plate 7, and then the cover plate 7 can be flipped downwards through the buckle belt 71, so that the hollow frame 5 is in an unobstructed state, and the electric fan 51 is subsequently started to speed up the flow of air near the balance body 1, so that the pungent odor is quickly dissipated.
