Description

Technical Field

[0001] The utility model relates to the technical field of electronic balances, in particular to an electronic balance equipped with a protective cover. Background Art

[0002] An electronic balance is a precision instrument that uses the principle of electromagnetic force balance for weighing. Its main components include sensors, a microprocessor, a display, and control buttons. When an object is placed on the balance's pan, the sensor senses the object's gravity and converts it into an electrical signal. This signal is processed by the microprocessor and ultimately displayed digitally on the display, indicating the object's mass.

[0003] When an electronic balance is not in use, a protective cover can be placed over it. This not only protects the balance from dust but also protects it from external impacts. However, during installation, conventional protective covers can accidentally collide with other parts of the balance, potentially damaging the balance's accuracy or structure. Therefore, a protective cover that is easy to install and does not affect the balance during installation is urgently needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose an electronic balance equipped with a protective cover.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-6 An electronic balance equipped with a protective cover comprises an electronic balance body 1 and a protective cover 3. A base 11 is fixedly provided at the bottom of the electronic balance body 1, and mounting posts 2 are fixedly provided vertically upward at the corners of the base 11. The protective cover 3 is adapted to be assembled above the base 11, and mounting cavities 31 are adapted to be opened at the corners of the protective cover 3 corresponding to the mounting posts 2. A mounting seat 4 is fixedly provided on the outside of the protective cover 3 near the mounting cavity 31, and a wedge-shaped movable block 7 is provided in the mounting seat 4 for horizontal movement, and a wedge-shaped pressure block 5 is provided on the top of the wedge-shaped movable block 7 for vertical movement. Among them, the specific structure of the electronic balance body 1 and its working method are both existing technologies currently disclosed on the market, which are common knowledge well known to those skilled in the art, and do not belong to the technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0022] The sidewalls near the top of the mounting post 2 each have a limit cavity 21 defined therein. A through-hole is provided on the protective cover 3 to match the limit cavity 21, and the mounting seat 4 is positioned outside the through-hole. The ends of the wedge-shaped pressure block 5 and the wedge-shaped movable block 7 that contact each other are each configured as an inclined surface, with the inclined surfaces matching each other. The other end of the wedge-shaped movable block 7 matches the limit cavity 21. The end of the wedge-shaped movable block 7 passes through the through-hole and into the limit cavity 21, thereby achieving a locking connection between the mounting post 2 and the protective cover 3.

[0023] A counterweight 51 is fixed to the top of the wedge-shaped pressure block 5, and the counterweight 51 is located on the top of the mounting base 4. A plurality of guide posts 6 are fixed vertically upward from the top of the mounting base 4, and each guide post 6 passes through the counterweight 51. The arrangement of the guide posts 6 ensures that the counterweight 51 and the wedge-shaped pressure block 5 remain perpendicular when moving up and down.

[0024] The bottom of the mounting base 4 is provided with an adjustment cavity 41 extending downwardly, and the bottom of the wedge-shaped movable block 7 is fixed downwardly with an adjustment member 71 vertically provided thereon, and the adjustment member 71 extends from the bottom of the adjustment cavity 41. By setting the adjustment member 71, the position of the wedge-shaped movable block 7 can be adjusted.

[0025] In this embodiment, when the user needs to install the protective cover 3, they only need to move the protective cover 3 downward from the top of the electronic balance body 1 so that the mounting posts 2 are inserted into the mounting cavities 31 provided in the protective cover 3. The user can then pull the wedge-shaped movable block 7 outward using the adjustment member 71. As the wedge-shaped movable block 7 moves outward, the inclined surface at its end can lift the wedge-shaped pressure block 5, allowing the wedge-shaped movable block 7 to move into the mounting seat 4.

[0026] Furthermore, when the user releases the adjustment member 71, the wedge-shaped pressure block 5 moves downward due to the pressure of the counterweight 51. As the wedge-shaped pressure block 5 moves downward, the inclined surface at its end pushes the wedge-shaped movable block 7 outward again, thereby pushing the wedge-shaped movable block 7 into the limiting cavity 21 in the mounting post 2. At this time, the mounting post 2 and the protective cover 3 are fixedly secured by the wedge-shaped movable block 7, thereby completing the installation of the protective cover 3.

[0027] Furthermore, when the user needs to remove the protective cover 3, he only needs to pull the wedge-shaped movable block 7 into the mounting seat 4 through the adjustment member 71, so that the wedge-shaped movable block 7 can be contacted with the locking device of the limiting cavity 21, thereby realizing the removal of the protective cover 3.

[0028] In the present invention, the protective cover 3 is assembled on the outside of the electronic balance body 1 through the mounting column 2, and the mounting column 2 and the protective cover 3 can be clamped and fixed by the adaptation setting between the wedge-shaped pressure block 5 and the wedge-shaped movable block 7, thereby ensuring the installation stability of the protective cover 3. This installation method is simple and convenient, and it is not easy to touch the electronic balance body 1 during the installation process, which is convenient for users to use.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
