Technical Field
[0001] This utility model relates to the field of electronic balance technology, specifically electronic balances. Background Technology
[0002] Electronic balances are precision measuring devices commonly used in laboratories and industries to accurately measure the mass of objects. Compared to traditional mechanical balances, electronic balances typically offer higher accuracy and sensitivity, providing faster and more direct readings.
[0003] When performing precise measurements with an electronic balance, it is usually necessary to use a wind shield to prevent excessive external wind from affecting the normal measurement of the balance. However, the existing wind shield mechanism has a relatively fixed height during use. When it is necessary to measure objects that are relatively tall, it is not easy to use the wind shield to protect the measured objects. Therefore, we propose the electronic balance.

A wind shield mechanism for protecting and preventing wind from weighing objects of different heights is inserted into the positioning groove. The wind shield mechanism is provided with a locking mechanism to prevent the wind shield mechanism from sliding. The balance base and the wind shield mechanism are connected and locked together by an installation mechanism.
[0006] Furthermore, the wind hood mechanism includes a first wind hood body, a second wind hood body, and an opening and closing plate. The first wind hood body is inserted into the positioning groove, the second wind hood body is slidably connected to the outside of the first wind hood body, and the opening and closing plate is rotatably connected to the top of the second wind hood body.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-3 This utility model provides a technical solution: an electronic balance, including a balance base 1, with multiple sets of support legs 2 fixedly installed at the bottom of the balance base 1, a tray 15 provided at the top of the balance base 1, a positioning groove 3 provided at the top of the balance base 1 and outside the tray 15, a wind shield mechanism 4 for protecting and preventing wind from weighing objects of different heights inserted into the positioning groove 3, a locking mechanism 5 provided on the wind shield mechanism 4 to prevent the wind shield mechanism 4 from sliding, and the balance base 1 and the wind shield mechanism 4 are connected and locked by an installation mechanism 6.
[0018] The balance base 1 and tray 15 are configured to measure the items to be inspected. The hood mechanism 4 can be inserted into the positioning slot 3, and the mounting mechanism 6 can prevent the hood mechanism 4 from falling out of the positioning slot 3 during use. The height of the hood mechanism 4 can be adjusted according to the height of the item being measured, making the hood mechanism 4 more adaptable and able to protect items of different heights. After the height of the hood mechanism 4 is adjusted, the locking mechanism 5 can be used to fix the hood mechanism 4, thereby preventing the height of the hood mechanism 4 from dropping during use and affecting the measurement and weighing of the item.
[0019] Please see Figure 1 and Figure 2 The wind shield mechanism 4 includes a first wind shield body 7, a second wind shield body 8, and an opening and closing plate 9. The first wind shield body 7 is inserted into the positioning groove 3. The second wind shield body 8 is slidably connected to the outside of the first wind shield body 7. The opening and closing plate 9 is rotatably connected to the top of the second wind shield body 8. A lifting handle is fixedly installed on the top of the opening and closing plate 9. A sealing gasket made of rubber material is fixedly connected to the bottom edge of the opening and closing plate 9.
[0020] When it is necessary to protect items of different heights, the second hood body 8 can be moved upward along the outside of the first hood body 7. In this way, the first hood body 7 and the second hood body 8 can work together to complete the windproof protection of the items. The opening and closing plate 9 makes it easy to open the top of the second hood body 8 to put the items in, and the rubber sealing gasket can prevent external dust and wind from flowing in through the gap between the opening and closing plate 9 and the second hood body 8.
[0021] Please see Figure 1 and Figure 2 The locking mechanism 5 includes an adsorption iron sheet 10, an adsorption magnet 11, a threaded rod 12, a locking nut 13, and a clearance groove 14. The clearance groove 14 is provided on the second hood body 8. Two sets of adsorption iron sheets 10 are fixedly installed on the outside of the first hood body 7. An adsorption magnet 11 that is adsorbed by the adsorption iron sheet 10 is fixedly connected to the inner wall of the second hood body 8. A threaded rod 12 is fixedly installed on the outside of the first hood body 7 at a position corresponding to the clearance groove 14. A locking nut 13 that fits against the second hood body 8 is threadedly connected to the outside of the threaded rod 12.
[0022] When the second hood body 8 moves upward along the outside of the first hood body 7, the mutually attracted iron sheet 10 and attracted magnet 11 can initially position the first hood body 7 and the second hood body 8, which can prevent the second hood body 8 from slipping when the positions of the first hood body 7 and the second hood body 8 are adjusted. After the second hood body 8 is adjusted, the locking nut 13 is rotated, which can move the locking nut 13 along the outside of the threaded rod 12, thereby fixing the second hood body 8 to the outside of the first hood body 7.
[0023] Please see Figure 1 and Figure 2 The installation mechanism 6 includes a connecting frame 16, a positioning piece 17, a connecting shaft 18, and a locking piece 19. The connecting frame 16 is fixedly installed on the outside of the first wind cover body 7. The positioning piece 17 is fixedly installed on one side of the balance base 1 at the position corresponding to the connecting frame 16. The connecting shaft 18, which is inserted below the positioning piece 17, is fixedly installed at the bottom of the connecting frame 16. An elliptical locking piece 19 that fits against the bottom of the positioning piece 17 is rotatably connected to the outside of the connecting shaft 18.
[0024] During the installation of the wind shield mechanism 4, the connecting shaft 18 and the elliptical locking piece 19 can be inserted below the positioning piece 17. After the locking piece 19 moves below the positioning piece 17, rotating the locking piece 19 can make the locking piece 19 misaligned with the positioning piece 17, thus preventing the wind shield mechanism 4 from leaving the interior of the positioning groove 3.
[0025] Please see Figure 1 and Figure 2 The first wind shield body 7, the second wind shield body 8, and the opening and closing plate 9 are all made of transparent acrylic material. The transparent acrylic material allows for easy observation of the weighing process of the item through the first wind shield body 7, the second wind shield body 8, and the opening and closing plate 9.
[0026] In use, firstly, the balance base 1 and tray 15 can measure the items to be inspected. The wind shield mechanism 4 can be inserted into the positioning slot 3, and the mounting mechanism 6 can prevent the wind shield mechanism 4 from falling out of the positioning slot 3 during use. Subsequently, the height of the wind shield mechanism 4 can be adjusted according to the height of the item being measured, making the wind shield mechanism 4 more adaptable and able to protect items of different heights. After the height of the wind shield mechanism 4 is adjusted, it can be fixed by the locking mechanism 5, thereby preventing the height of the wind shield mechanism 4 from decreasing during use and affecting the measurement and weighing of the item. When it is necessary to protect items of different heights, the second wind shield body 8 can be moved upward along the outside of the first wind shield body 7. In this way, the first wind shield body 7 and the second wind shield body 8 can work together to complete the windproof protection of the item. The opening and closing plate 9 makes it easy to open the top of the second wind shield body 8 to put in the item, and the rubber... The sealing gasket prevents external dust and wind from flowing in through the gap between the opening plate 9 and the second hood body 8. When the second hood body 8 moves upward along the outside of the first hood body 7, the mutually attracted iron plates 10 and magnets 11 can initially position the first hood body 7 and the second hood body 8, preventing the second hood body 8 from slipping during the adjustment of the positions of the first hood body 7 and the second hood body 8. After the second hood body 8 is adjusted, rotating the locking nut 13 will allow the locking nut 13 to move along the outside of the threaded rod 12, thereby fixing the second hood body 8 to the outside of the first hood body 7. When the hood mechanism 4 is installed, the connecting shaft 18 and the elliptical locking piece 19 can be inserted below the positioning piece 17. After the locking piece 19 moves below the positioning piece 17, rotating the locking piece 19 will cause the locking piece 19 to be misaligned with the positioning piece 17, thus preventing the hood mechanism 4 from dislodging from the interior of the positioning groove 3.
