Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0026] Example

[0027] Please refer to Figure 1-5 As shown, the utility model provides a technical solution: a dust-proof mechanism for intelligent instruments;

[0028] The left end of the lower dust cover 1 is fixedly installed with a mounting box 4, the inner end of the mounting box 4 is rotatably installed with a gear 5, the inner end of the gear 5 is fixedly installed with a connecting rod 7, the outer end of the connecting rod 7 is clamped with a gripping rod 8, the inner end of the gripping rod 8 is provided with a clamping groove 9, the outer end of the connecting rod 7 is fixedly installed with a clamping block 10, and the clamping block 10 is clamped and installed at the inner end of the clamping groove 9. The rear end of the gripping rod 8 is fixedly installed with a limiting block 11 at an equal angle, and the inner end of the mounting box 4 is provided with a limiting groove 6 at an equal angle. The positions of the limiting groove 6 and the limiting block 11 correspond to each other, which is suitable for intelligent instruments of different specifications;

[0029] The upper dust cover 2 is snap-fitted and installed inside the lower dust cover 1. The inner end of the upper dust cover 2 is provided with tooth grooves 12 at equal intervals. A combination lock 16 is fixedly installed on the left side of the top of the upper dust cover 2. The tooth groove 12 is meshed and connected with the gear 5, which is easy to adjust and has high flexibility in use.

[0030] The transparent top plate 3 is rotatably mounted on the upper end of the upper dust cover 2, and a hollow groove 13 is provided at the inner end of the transparent top plate 3, and a movable rod 14 is passed through the inner end of the hollow groove 13, and a light shielding portion 15 is provided at the outer end of the movable rod 14. A lock buckle 17 is fixedly mounted on the left end of the transparent top plate 3, and the lock buckle 17 is snap-fitted and mounted on the inner end of the upper dust cover 2, which can achieve the effects of transparent visibility and light shielding protection while effectively preventing dust, and has a simple and practical structure and is easy to operate.

[0031] Specific working principle:

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the dustproof mechanism of the intelligent instrument is used, firstly, according to the size of the intelligent instrument to be dustproofed, the height of the lower dust cover 1 and the upper dust cover 2 is adjusted. When adjusting, the grip 8 is pulled forward to move the limit block 11 at the rear end of the grip 8 out from the inside of the limit slot 6 opened at the front end of the installation box 4, and then the grip 8 is rotated. Because the slot 9 opened inside the grip 8 is engaged with the block 10, when the grip 8 is rotated, the grip 8 drives the connecting rod 7 and the gear 5 to rotate together. When the gear 5 rotates, the gear 5 is engaged with the tooth groove 12, driving the upper dust cover 2 to move upward or downward at the inner end of the lower dust cover 1. After the upper dust cover 2 is adjusted to the required height, the grip 8 is pushed backward, and the slot 9 slides outside the block 10, so that the limit block 11 at the rear end of the grip 8 is engaged with the inside of the limit slot 6, so that the grip 8 is fixed and the gear 5 is prevented from rotating.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the transparent top plate 3 is made of highly transparent acrylic material. When the instrument needs to be controlled, the correct password is entered through the password lock 16, and the lock core is moved out from the inner end of the lock buckle 17, so that the transparent top plate 3 can be opened for control. If the instrument needs to be shading, the movable rod 14 located on the right side of the hollow groove 13 is moved to the left side of the transparent top plate 3 while rotating, and the shading part 15 rolled up on the outside of the movable rod 14 is unfolded inside the hollow groove 13, so that the shading treatment of the transparent top plate 3 can be achieved, which can effectively prevent dust and provide shading protection. The above completes a series of operations of the dustproof mechanism of the intelligent instrument. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
