[0002] As we all know, electronic balances are precision weighing products that are the most accurate for weighing small amounts, have the smallest range, and the lowest graduation value. They are commonly used in industry, agriculture, commerce, schools, hospitals, scientific research institutions, and other units.

[0003] However, when using existing electronic balances, objects are generally placed directly on the weighing platform for measurement. The objects are exposed to the outside world and are easily affected by external airflow, which may lead to deviations in the measured data. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4An electronic balance with good windproof effect includes a base plate 1, a body 2, a protective shell 4 and a connecting mechanism 5. The body 2 is arranged on the top of the base plate 1, and a weighing platform 3 is provided on the top of the body 2. The protective shell 4 is connected to the base plate 1 through the connecting mechanism 5. The connecting mechanism 5 includes a vertical block 6, a sliding block 7, a fixed block 8, a sliding assembly 9, a telescopic rod 10, a long plate 11 and a bolt 12. The bottom of the vertical block 6 is connected to the top of the base plate 1, and one end of the sliding block 7 is sleeved on the vertical block 6. The other end of the sliding block 7 is connected to the protective shell 4, the bottom of the fixed block 8 is connected to the top of the base plate 1, the sliding component 9 is arranged on the fixed block 8, one end of the sliding component 9 is in contact with the bottom of the sliding block 7, one end of the telescopic rod 10 is connected to the sliding component 9, the other end of the telescopic rod 10 is connected to one end of the long plate 11, one end of the bolt 12 is threadedly connected to the long plate 11 and the vertical block 6, and a controller is provided on the body 2, and the controller is electrically connected to the body 2.

[0023] When in use, first place the device in the designated position, then support the device through the bottom plate 1, then place the items to be weighed on the weighing platform 3, then start the sliding assembly 9 on the fixed block 8 to make the sliding assembly 9 descend, and the bottom of the sliding block 7 sleeved on the vertical block 6 contacts the sliding assembly 9, so that when the sliding assembly 9 descends, the sliding block 7 will descend on the vertical block 6, thereby driving the protective shell 4 to descend, so that the bottom of the protective shell 4 contacts the body 2, and the protective shell 4 covers the items. The protective shell 4 is made of transparent material, and then the staff controls the body 2 to weigh the items. When the sliding assembly 9 descends, the extension on the sliding assembly 9 The retractable rod 10 will be extended, and the length that the telescopic rod 10 can be extended is long enough. The protective shell 4 contacts the top of the body 2 and will not affect the measurement result. Because there is only a weighing sensor at the bottom of the weighing platform 3, the protective shell 4 contacts the body 2, and the weighing sensor will not work. The body 2 is a conventional technology on the market, including structures such as a weighing sensor, a display screen, and an operation button. People in this technical field are well aware of its principle and will not be described in detail here. When weighing items, the protective shell 4 covers the items and the weighing platform 3 to prevent external airflow from affecting the accuracy of weighing. When the staff is back, start the sliding component 9 to drive the protective shell 4 to rise and return to Figure 1 When the sliding assembly 9 rises, the telescopic rod 10 will shrink. Since the long plate 11 on the telescopic rod 10 is connected to the vertical block 6 by the bolt 12, the telescopic rod 10 shrinks to the position. Figure 1When the protective shell 4 is used for a long time and is damaged and needs to be replaced, the staff can unscrew the bolts 12 by hand to separate the bolts 12 from the vertical block 6 and the long plate 11, and then the staff can pull the telescopic rod 10 by hand to drive the long plate 11 to rise, so that the long plate 11 is separated from the vertical block 6, and a sufficient distance is directly reserved between the long plate 11 and the vertical block 6. Then the staff can pull the protective shell 4 by hand again to make the sliding block 7 rise on the vertical block 6 and separate the sliding block 7 from the vertical block 6. Since the vertical block 6 is separated from the long plate 11, enough space is reserved, so that The sliding block 7 is separated from the vertical block 6, and the protective shell 4 is set on the sliding block 7, so that the protective shell 4 can be removed and replaced with a new protective shell 4. The new protective shell 4 comes with a sliding block 7, and the new protective shell 4 can be purchased from the manufacturer. No specific description is given here. The sliding assembly 9 in the text is a conventional technology on the market, including components such as slide grooves, sliders, motors and screw rods. People in this technical field are clearly aware of its working principle, and no specific description is given here. The dimensions of all components in this structure are not described in detail here, and need to be produced according to actual conditions. The control method of the present utility model is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in this field, and the present utility model is mainly used to protect mechanical devices, so the present utility model no longer explains the control method and wiring arrangement in detail.

[0024] The anti-slip effect of the bottom of the above-mentioned base plate 1 is poor. When the base plate 1 contacts a smooth object, it is easy to slip. In order to solve this problem, in this embodiment, the bottom of the base plate 1 is provided with anti-slip grooves, and the anti-slip grooves are fixedly connected to the bottom of the base plate 1. The anti-slip grooves are provided with several strips.

[0025] The protective shell 4 is inconvenient to pull. In order to solve this problem, in this embodiment, a handle 13 is provided on the top of the protective shell 4.

[0026] In order to improve the connection effect, in this embodiment, the handle 13 is fixedly connected to the top of the protective shell 4.

[0027] The bolts 12 are prone to rust after long-term use. To solve this problem, in this embodiment, the bolts 12 are made of stainless steel.

[0028] The above device is inconvenient to operate. In order to solve this problem, in this embodiment, the controller is electrically connected to the sliding component 9.
