Description

Technical Field

[0001] The utility model relates to the technical field of electronic balances, and in particular to a dust-proof balance. Background Art

[0002] An analytical balance is an indispensable precision measuring instrument in quantitative analysis work. Analytical balances are widely used in industries such as industry, medicine, and chemical engineering.

[0003] Since the objects to be measured by the analytical balance have extremely high requirements for measurement accuracy, even the slightest error in the measurement process may affect the measurement results. After the analytical balance is placed for a long time, without a good sealing structure, more or less dust will inevitably remain on its surface, affecting the measurement results of the balance to be measured.

[0004] In order to prevent dust, the existing analytical balances are equipped with protective covers at the upper ends. The protective covers are assembled by brackets and glass panels and installed on the balance. Generally, a cover plate is provided at the top to place the object, but the cover plate needs to be placed aside, which may cause the cover plate to be stained with stains on the table, resulting in easy influence on the inside of the balance if not cleaned subsequently, thus affecting the analysis.

[0030] The following describes the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0031] Refer to Figures 1-5 , Figure 1 which is a schematic structural diagram of a balance for some embodiments of the present utility model; Figure 2 which is a schematic structural connection diagram of a frame-shaped bracket for some embodiments of the present utility model; Figure 3 which is a schematic structural diagram of a protective cover for some embodiments of the present utility model; Figure 4 which is a schematic structural diagram of a sealing strip for some embodiments of the present utility model; Figure 5 which is a schematic diagram of the structural connection between a frame-shaped bracket and a slider for some embodiments of the present utility model.

[0032] The present utility model provides a dust-proof balance, which includes a balance body 1. On both sides of the front and rear ends of the top of the balance body 1, chutes 2 are provided. Sliders 21 are provided in the chutes 2. On two of the sliders 21 at one end of the top of the balance body 1, a first protective cover 22 is provided, and on two of the sliders 21 at the other end, a second protective cover 23 is provided. The first protective cover 22 and the second protective cover 23 are in the shape of equal semi-frame types, and when combined, they can form an integral square-shaped protective cover 3 that can cover the entire top of the balance body 1.

[0033] By providing sliders 21 under the two semi-frame protective covers and allowing the sliders 21 to drive the semi-frame protective covers to move left and right, the opening and closing of the protective cover 3 can be realized. In this way, it is not necessary to set a cover plate, and it can also avoid the cover plate being stained by the desktop stains, which affects the analysis.

[0034] According to some embodiments of the present utility model, optionally, a first sealing strip 24 and a second sealing strip 25 are respectively provided on the opposite sides of the first protective cover 22 and the second protective cover 23. When the two semi-frame protective covers are combined, gaps will be generated. The sealing strips can seal well to avoid dust from entering the balance.

[0035] According to some embodiments of the present utility model, optionally, a groove 26 is provided on one side of the first sealing strip 24 facing the second sealing strip 25, and a protrusion 27 matching the groove 26 is provided on one side of the second sealing strip 25 facing the first sealing strip 24. The groove 26 and the matching protrusion 27 are respectively provided on the opposite sides of the sealing strip so as to achieve better sealing when combined.

[0036] According to some embodiments of the present utility model, optionally, the slider 21 is an electric slider, and a control button 28 for controlling the electric slider is provided on one side of the balance body 1. A slide rail 29 is arranged through the chute 2 to connect the slide rail with the slider 21, and then the use of an electric slider is easy to control and does not require manual opening and closing.

[0037] According to some embodiments of the present utility model, optionally, a frame-shaped bracket 4 matching the bottoms of the first protective cover 22 and the second protective cover 23 is provided between the first protective cover 22 and the second protective cover 23 and the slider 21. Fixing the frame-shaped bracket 4 on the top of the protective cover 3 can prevent the bottom of the protective cover 3 from rubbing against the top of the balance body 1 and causing fragmentation when using the glass.

[0038] According to some embodiments of the present utility model, optionally, a plurality of connecting grooves 41 are provided at the bottom of the frame-shaped bracket 4, and connecting blocks 42 matching the number, size and shape of the connecting grooves 41 are provided at the top of the slider 21. The detachable separation through the connecting grooves 41 and the connecting blocks 42 facilitates the removal of the protective cover 3 for cleaning.

[0039] According to some embodiments of the present utility model, optionally, the inner wall of the connecting groove 41 is made of iron, and the connecting block 42 is made of magnet. Adsorption by the magnet facilitates disassembly and can also ensure the connection between the frame-shaped bracket 4 and the slider 21.
