Positioning mechanisms are fixedly connected to the side ends of both the base 1 and the upper side of the side end of the box frame 2. Box doors 6 are hingedly connected to the side ends of the box frame 2. A sealing gasket 17 is fixedly connected to the side end of the box door 6, which increases the sealing performance between the box door 6 and the box body, and prevents dust from entering the interior of the instrument chassis through the gap between the box door 6 and the box frame 2. The box door 6 is connected to the box frame 2 through a buckle lock 18, which is convenient for fixing the box door 6 on the box frame 2 and at the same time convenient for opening the box door 6. A side plate 7 is provided on one side of the interior of the box frame 2 away from the positioning mechanism. A plurality of ventilation openings 19 are provided on the side plate 7. The height of the end of the ventilation opening 19 close to the box frame 2 is higher than the height of the end of the ventilation opening 19 away from the box frame 2, which prevents rainwater from entering the interior of the instrument chassis and at the same time plays a role in ventilation and heat dissipation. Dust-proof nets 20 are installed inside each ventilation opening 19 to achieve the effect of dust prevention. Two sliding strips 8 are fixedly connected to the side end of the side plate 7, and sliding grooves 9 are provided at the corresponding positions on the box frame 2.

[0031] In this embodiment, when it is necessary to repair the electronic instruments inside the instrument chassis, if the electronic instruments can be repaired by simply opening the cabinet door 6, then only the cabinet door 6 needs to be opened for repair. When it is necessary to overhaul the electronic instruments on the inner side, the box cover 3 is removed from the box frame 2, then the side plate 7 is pulled out from the inside of the box frame 2, and then the box frame 2 is pulled out, so that the periphery of the electronic instruments is exposed, which is convenient for repairing the electronic instruments inside the instrument box body. Through the sliding fit between the convex strip 5 on the box frame 2 and the convex groove 4 on the base 1, it is convenient to install the box frame 2 on the base 1. Through the cooperation between the sliding strip 8 and the sliding groove 9, it is convenient to install the side plate 7 on the box frame 2. Through the sliding fit between the two convex grooves 4 on the box cover 3 and the two convex grooves 4 on the box frame 2, it is convenient to install the box cover 3 on the box frame 2. At the same time, the side plate 7 is positioned between the box frame 2 and the base 1 through the box cover 3, so as to facilitate assembling them into an instrument chassis, thus facilitating its assembly. When it is necessary to install a large number of electronic instruments and relatively tall electronic instruments, through the cooperation between the two convex strips 5 on the box frame 2 and the upper convex groove 4 on the box frame 2, it is convenient to longitudinally connect multiple box frames 2 together, thereby increasing the space inside the instrument chassis, facilitating the installation of a large number of electronic instruments and relatively tall electronic instruments, and improving the practicality of its use.

[0032] Please refer to Figure 1 , Figure 5 and Figure 6 , the positioning mechanism includes a U-shaped plate 10. Two positioning plates 11 are slidably arranged inside the U-shaped plate 10. Grooves 12 are arranged at the inner side ends of the U-shaped plate 10. Rack bars 13 are fixedly connected to both of the two positioning plates 11. Both of the two rack bars 13 are located inside the grooves 12. A rotating shaft 14 is rotatably connected to the U-shaped plate 10. One end of the rotating shaft 14 extending into the groove 12 is fixedly connected with a gear 15. The gear 15 meshes with the two rack bars 13. The gear 15 is located at the middle position between the two rack bars 13. A rotating groove 16 is arranged at the end of the rotating shaft 14 away from the gear 15. The rotating groove 16 is arranged as a regular hexagon.

[0033] In this embodiment, insert a hex wrench into the rotating groove 16. Rotate the rotating shaft 14 clockwise through the hex wrench. The rotating shaft 14 drives the gear 15 to rotate. The rotation of the gear 15 causes the two rack bars 13 to move towards both sides. The rack bars 13 drive the two positioning plates 11 to move towards both sides, and the positioning plates 11 cover the convex groove 4, so as to position the convex strip 5 inside the convex groove 4, ensuring the stable connection between the box frame 2 and the base 1, between the box frame 2 and the box frame 2, and between the box frame 2 and the box cover 3.

[0034] In summary, when the overall device is in use:

[0035] First, install a corresponding frame for mounting the electronic instrument on the base 1, and then install the electronic instrument on the corresponding frame. After the installation is completed, connect the box frame 2 to the base 1 by inserting the convex strip 5 into the inside of the convex groove 4. Connect a corresponding number of box frames 2 together. Install the side plate 7 in the corresponding box frame 2 by inserting the sliding strip 8 into the inside of the sliding groove 9. Then insert the two convex strips 5 on the box cover 3 into the inside of the two convex grooves 4 on the upper box frame 2, so that the box cover 3 is connected to the uppermost box frame 2. A corresponding sealing structure can be added at the connection between each structure for sealing to prevent dust from entering the inside of the instrument box. Then insert the hex wrench into the inside of the rotation groove 16, and rotate the rotating shaft 14 clockwise through the hex wrench. The rotating shaft 14 drives the gear 15 to rotate. The rotation of the gear 15 causes the two racks 13 to move to both sides. The racks 13 drive the two positioning plates 11 to move to both sides, and the positioning plates 11 cover the convex grooves 4, thereby positioning the convex strips 5 inside the convex grooves 4, and thus completing the assembly of the instrument chassis.
