Description

Technical Field

[0001] The utility model belongs to the technical field of electronic balances, in particular to a high-precision touch-proof electronic balance. Background Art

[0002] Electronic balance is a kind of precision weighing product that can accurately weigh light weight, has a small measuring range and low graduation value. It is usually used in industry, agriculture, commerce, schools, hospitals, scientific research and other units, and these units often need to make rapid measurements and have certain requirements for sensitivity and stability.

[0003] In order to ensure the accuracy of measurement, the object needs to be placed in the center of the balance. Currently, tweezers or other clamping devices are generally used to clamp and place the object (to prevent hand sweat from affecting the accuracy). When placing the object, only one side is considered. As a result, it is difficult to ensure that it is in the center position when placing it, which requires repeated attempts. This is time-consuming and labor-intensive, and also affects the overall weighing accuracy. Utility Model Content

[0004] The purpose of the utility model is to provide a high-precision touch-proof electronic balance in order to solve the above-mentioned problems.

[0005] The technical solution adopted by the utility model is as follows: a high-precision touch-proof electronic balance, including a base, a weighing balance is arranged on the base, a protection frame for covering the weighing balance is installed on the base, a camera is arranged on the inner wall of the upper end of the protection frame just above the weighing balance, a PCB mainboard and a display screen are arranged in the base, the camera and the display screen are electrically connected to the PCB mainboard, the camera collects images of objects placed on the weighing balance, and transmits the images to the display screen through the PCB mainboard for display.

[0006] In a preferred embodiment, the four ends of the protection frame are hinged with transparent protection plates through hinges, and the outer ends of the transparent protection plates are provided with handles.

[0007] In a preferred embodiment, leveling supports are provided at the four corners of the bottom of the base, a threaded rod is integrally provided at the upper end of the leveling support, and a threaded hole is opened on the bottom wall of the base to meet the connection with the threaded rod.

[0008] In a preferred embodiment, the outer end surface of the leveling support is protrudingly formed with anti-slip lines.

[0009] In a preferred embodiment, a level bubble is embedded in the base.

[0010] In a preferred embodiment, one side of the display screen is further provided with an operation button on the base and a speaker electrically connected to the PCB mainboard.

[0011] In summary, due to the adoption of the above-mentioned technical scheme, the beneficial effect of the utility model is as follows: a camera is designed directly above the weighing balance, and when placing objects, the image of the balance within a 360° range can be directly viewed through the camera, so that when placing objects, the current position of the object can be known from the display screen, so that the corresponding center position can be found quickly, thereby improving the accuracy of subsequent measurements, and having advantages that current electronic balances do not have.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] Reference Figure 1-4 A high-precision touch-proof electronic balance comprises a base 4, on which a weighing balance 11 is arranged, on which a protective frame 2 for covering the weighing balance 11 is installed, and directly above the weighing balance 11, a camera 1 is arranged on the inner wall of the upper end of the protective frame 2, and a PCB main board 12 and a display screen 7 are arranged in the base 4, the camera 1 and the display screen 7 are electrically connected to the PCB main board 12, the camera 1 collects an image of an object placed on the weighing balance 11, and transmits the image to the display screen 7 through the PCB main board 12 for display, and the camera 1 is designed directly above the weighing balance 11, and when placing an object, the 360° range image of the weighing balance 11 can be directly viewed through the camera 1, so that when placing an object, the current placement position can be known from the display screen 7, and the corresponding center position can be quickly found, thereby improving the accuracy of subsequent measurements.

[0019] In addition, a center display frame (preferably red, which can be adjusted accordingly according to the diameter of different objects) can be set on the display screen 7 according to the diameter of different objects. That is, after the object is placed within the frame, it is the center position, which makes it easier to find the center point.

[0020] It should be mentioned that the above are existing technologies that have been implemented, and how to implement them will not be described in detail here.

[0021] Furthermore, the four ends of the protection frame 2 are hinged with transparent protection plates 3 through hinges, and the outer ends of the transparent protection plates 3 are provided with handles 5. The closed transparent protection plates 3 can be used as wind shields to prevent external wind or wind raised by hands from contacting the electronic balance, thereby improving the overall detection accuracy. When it is necessary to release or take out materials, just open the corresponding transparent protection plate 3.

[0022] Furthermore, a level bubble 10 is embedded in the base 4, and leveling supports 6 are provided at the four corners of the bottom of the base 4. A threaded rod is integrally provided at the upper end of the leveling support 6, and a threaded hole that is connected to the threaded rod is opened on the bottom wall of the base 4. The overall levelness after placement can be checked through the level bubble 10. When it is not level, the corresponding leveling support 6 is rotated upward or downward until it is level, thereby ensuring the subsequent weighing accuracy.

[0023] Furthermore, the outer end surface of the leveling support 6 is protruded to form anti-skid patterns, and the anti-skid patterns can increase the friction when the user holds the leveling support 6, and it is not easy to get loose.

[0024] Furthermore, an operation button 8 and a speaker 9 electrically connected to the PCB main board 12 are provided on one side of the display screen 7 on the base 4. The operation button 8 can be used to control the overall work, such as peeling, weighing and other operations.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
