It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0031] See also Figures 1 to 6 The embodiment of the utility model provides a high-precision electronic balance, comprising: an electronic scale 1, a level bubble 2 and a weighing pan 3 are provided on the upper surface of the electronic scale 1, a glass cover 4 is installed on the upper surface of the electronic scale 1, a plurality of adjustment structures 5 are provided on the lower surface of the electronic scale 1, and an auxiliary structure 6 is provided on the lower surface of the electronic scale 1.

[0032] In the embodiments of the present invention, please refer to Figures 2 to 5The adjustment structure 5 includes a fixed column 501, which is fixedly connected to the electronic scale 1. The inner wall of the fixed column 501 is threadedly connected to an adjusting rod 502. The lower end of the adjusting rod 502 is rotatably connected to a mounting frame 503. The arc surface of the adjusting rod 502 is fixedly connected to a turntable 504. The top side of the inner wall of the mounting frame 503 is fixedly connected to two round rods 506. The arc surfaces of the two round rods 506 are slidably connected to an adjusting block 507. Both sides of the adjusting block 507 are provided with positioning grooves 508. The positioning grooves 508 are fixed to the top of the inner wall of the mounting frame 503. The inner wall is connected to a receiving groove 509, and the inner wall of the positioning groove 508 is slidably connected to a limiting rod 510. The surface of the limiting rod 510 is slidably connected to the installation frame 503. The surface of the limiting rod 510 is covered with a spring 511. The two ends of the spring 511 are respectively fixedly connected to the limiting rod 510 and the inner wall of the installation frame 503. The outer surface of the installation frame 503 is slidably connected to a mounting ring 512. The surface of the mounting ring 512 is provided with two limiting holes 513. The inner wall of the limiting hole 513 is slidably connected to the limiting rod 510. The outer surface of the mounting ring 512 is fixedly connected with a protective cover 514. The electronic scale 1 is leveled by operating the turntable 504. The adjustment block 507 can make the limit rod 510 slide in or out of the mounting frame 503. The limit rod 510 is used to limit the mounting ring 512, which is convenient for the user to replace the damaged mounting ring 512 and protective cover 514. The arc surface of the turntable 504 is fixedly connected with a plurality of anti-skid protrusions 505. The plurality of anti-skid protrusions 505 are evenly distributed on the turntable 504. 505 increases the friction of the arc surface of the turntable 504, making it easier for the user to operate the turntable 504. The lower surface of the protective cover 514 is provided with a plurality of anti-slip grooves 515. The anti-slip grooves 515 increase the friction on the surface of the protective cover 514, so that the overall support effect of the protective cover 514 and the mounting ring 512 is better. The lower surface of the mounting frame 503 is provided with two reserved grooves 516. The reserved grooves 516 are arc-shaped grooves. With the help of the reserved grooves 516, it is convenient for the user to insert his fingers into the mounting frame 503 to operate the adjustment block 507.

[0033] In the embodiments of the present invention, please refer to Figure 6The auxiliary structure 6 includes a slide rail 61, which is fixedly connected to the electronic scale 1, and the inner wall of the slide rail 61 is slidably connected to the auxiliary frame 62, and the inner wall of the auxiliary frame 62 is abutted against the curtain 63. The lower surface of the slide rail 61 is fixedly connected to a fixing plate 64, and the lower surface of the fixing plate 64 is threadedly inserted with a screw 65. The lower surface of the auxiliary frame 62 is provided with a circular hole 66, and the inner wall of the circular hole 66 is slidably connected to the screw 65. The auxiliary frame 62 is conveniently fixed to the slide rail 61 by the screw 65, and the curtain 63 is stored by the auxiliary frame 62 when the electronic scale 1 is not in use. The curtain 63 is operated to cover and protect the electronic scale 1. The upper surface of the auxiliary frame 62 is rotatably connected to a cover plate 67, and the cover plate 67 is used to shield the upper surface of the auxiliary frame 62 from dust. The upper end of the screw 65 is arc-shaped, and the upper end of the screw 65 is arc-shaped, which is convenient for the screw 65 to slide into the circular hole 66.

[0034] The working principle of a high-precision electronic balance provided by the utility model is as follows: by setting an adjustment structure 5, rotating the turntable 504, the turntable 504 drives the adjustment rod 502 to rotate, and the adjustment rod 502 moves along the fixing column 501 with the help of the thread in the direction away from or close to the electronic scale 1. During this process, the adjustment rod 502 always rotates with the mounting frame 503, and the mounting frame 503, the mounting ring 512 and the protective cover 514 always support the adjustment rod 502. When the mounting ring 512 and the protective cover 514 need to be replaced, the adjustment block 507 is pressed from bottom to top, and the adjustment block 507 extends into the mounting frame 503 along the round rod 506. During this process, the spring 511 is always in a compressed state. The spring 511 in the compressed state always gives the limit rod 510 an elastic force close to the adjustment block 507, and the limit rod 510 moves along both sides of the adjustment block 507. One end of the limit rod 510 moves from the positioning groove 508 to the storage groove 509 In the process, the limiting rod 510 is away from one end of the adjustment block 507, and gradually away from the limiting hole 513 on the mounting ring 512, until it is completely out of the limiting hole 513, and the limiting of the mounting ring 512 is released. Then, the mounting ring 512 and the protective cover 514 are operated to slide downward and away from the mounting frame 503, and a new mounting ring 512 and the protective cover 514 are taken out and put on the mounting frame 503 from bottom to top, and then the adjustment block 507 is pulled in the direction away from the mounting frame 503, and the limiting rod 510 is retracted. The receiving groove 509 moves to the positioning groove 508, and the end of the limiting rod 510 away from the adjusting block 507 gradually extends into the limiting hole 513, so that the mounting ring 512 and the protective sleeve 514 are fixed on the mounting frame 503. Among them, the friction of the arc surface of the turntable 504 is increased by the anti-slip protrusion 505, which facilitates the user to operate the turntable 504. The friction on the surface of the protective sleeve 514 is increased by the anti-slip groove 515, so that the overall support effect of the protective sleeve 514 and the mounting ring 512 is better.

[0035] By setting up the auxiliary structure 6, the curtain 63 in the auxiliary frame 62 is operated to cover the electronic scale 1. When not in use, the curtain 63 is placed in the auxiliary frame 62. When the auxiliary frame 62 needs to be removed, the screw 65 is turned, and the screw 65 moves downward along the fixed plate 64 with the help of the thread. The screw 65 slides downward out of the circular hole 66, releasing the limit on the auxiliary frame 62, and then the auxiliary frame 62 is moved in the direction away from the electronic scale 1, so that the auxiliary frame 62 moves out of the slide rail 61. Among them, the cover plate 67 is used to shield the upper surface of the auxiliary frame 62 from dust. The upper end of the screw 65 is arc-shaped, which facilitates the screw 65 to slide into the circular hole 66.
