[0025] A sealing pad 3 is provided at the bottom end of the dust cover 2. The sealing pad 3 is located above the electronic balance body 1 and plays a buffering role to prevent the dust cover 2 from colliding with the electronic balance body 1 and damaging the electronic balance body 1 when falling.

[0026] The adjustment mechanism 4 includes a first slide groove 401, a first slider 403 is slidably provided inside the first slide groove 401, two first sliders 403 are provided, and the movement of the second slide groove 405 is guided and limited. The top of the first slider 403 is provided with a second slide groove 405, and two second slide grooves 405 are provided, which are located on both sides of the electronic balance body 1. A second slider 406 is slidably provided inside the second slide groove 405, and the up and down movement of the dust cover 2 is guided and limited.

[0027] The first slide groove 401 is internally rotated with a bidirectional screw rod 402, which is threadedly connected to the middle of the first slider 403, and can drive the two first sliders 403 to move synchronously in the opposite direction. The two ends of the bidirectional screw rod 402 pass through the two sides of the first slide groove 401, and the two ends of the bidirectional screw rod 402 are provided with a first rotating disk 404, which is convenient for driving the rotation of the bidirectional screw rod 402;

[0028] The second slide groove 405 is internally rotated with an adjusting screw 407, which is threadedly connected to the middle part of the second slider 406. The second slider 406 can be driven to move linearly by the rotation of the adjusting screw 407. The top of the adjusting screw 407 passes through one side of the second slide groove 405. The top of the adjusting screw 407 is provided with a second rotating disk 408 to facilitate the rotation of the adjusting screw 407.

[0029] A third slide groove 409 is provided on the display surface of the electronic balance body 1, and two third slide grooves 409 are provided. A third slider 4011 is slidably provided inside the third slide groove 409 to guide and limit the movement of the dustproof plate 4010. The top of the two third sliders 4011 is provided with a dustproof plate 4010. The dustproof plate 4010 is made of a transparent material and is used to prevent dust from the display surface of the electronic balance body 1 without affecting the reading of the value on the display surface.

[0030] The third slide groove 409 and the third slider 4011 are both arranged in a T shape, which limit the dustproof plate 4010 and protect the dustproof plate 4010 from falling when the electronic balance is carried.

[0031] Example 2

[0032] The fixing mechanism 5 includes a card slot 501. Two card slots 501 are provided, respectively located on both sides of the electronic balance body 1. The card slots 501 are engaged with the second slider 406 to preliminarily locate the position of the dust cover 2.

[0033] A positioning hole 503 is provided inside the second slider 406, and a positioning rod 502 is provided inside the slot 501. The positioning rod 502 is engaged with the positioning hole 503. The engagement between the positioning rod 502 and the positioning hole 503 further limits the position of the dust cover 2 to improve stability. A connecting plate 504 is provided at the top of the positioning rod 502. A reset spring 505 is connected between the connecting plate 504 and the slot 501 to protect the positioning rod 502 from being lost and to elastically reset the positioning rod 502 so that the positioning rod 502 can be reset and inserted into the corresponding positioning hole 503.

[0034] When in use, first rotate the second rotating disk 408, the rotation of the second rotating disk 408 drives the rotation of the adjusting screw rod 407, and the rotation of the adjusting screw rod 407 drives the movement of the second slider 406. Since the second slider 406 is engaged with the card slot 501, the movement of the second slider 406 drives the movement of the card slot 501, thereby driving the dust cover 2 to move upward, and then put the objects to be weighed into the weighing plate. After weighing, the dust cover 2 is moved downward in the same way;

[0035] Pull the connecting plate 504 upward, the movement of the connecting plate 504 drives the positioning rod 502 to move upward, and the first rotating disk 404 is rotated at the same time. The rotation of the first rotating disk 404 drives the rotation of the bidirectional screw rod 402, thereby driving the movement of the first slider 403. The movement of the first slider 403 drives the movement of the second slide groove 405 and the second slider 406, thereby separating the second slider 406 from the slot 501, so that the dust cover 2 is separated from the adjustment mechanism 4, which is convenient for disassembly and cleaning of the dust cover 2. Loosen the connecting plate 504, and under the action of the reset spring 505, the positioning rod 502 extends into the interior of the slot 501, so that the positioning rod 502 will not be lost when not in use and can be reset;

[0036] When it is needed, slide the third slider 4011, and the third slider 4011 drives the dustproof plate 4010 to slide to the left in the third slide groove 409. Since the third slider 4011 and the third slide groove 409 are both T-shaped, the dustproof plate 4010 will not fall off, and the dustproof plate 4010 is convenient for dustproof protection of the display screen of the electronic balance body 1.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
