The above constitutes the basic structure of the utility model.
[0030] Further, the chassis is a rectangular box body with a six-sided structure, which is fixedly connected by a bottom plate 1, a front plate 2, a rear plate 3, a top plate 4, a left plate 5 and a right plate 6. The horizontal industrial control board 8 and the horizontal card rack assembly 7 are fixed on the rear baffle 3 at intervals. A plurality of connection ports are provided on the rear baffle 3. A vibration anti-slip assembly is provided between the horizontal card rack assembly 7 and the bottom plate 1. In this arrangement, one end of the horizontal card rack assembly 7 is fixed on the rear baffle 3, the bottom of the horizontal card rack assembly 7 is fixed on the bottom plate 1, and a vibration anti-slip assembly is provided between the horizontal card rack assembly 7 and the bottom plate 1, so that the horizontal card rack assembly 7 is fixed more firmly, and the purpose of vibration anti-slip is achieved.
[0031] Furthermore, the vibration anti-slip assembly includes a mounting plate 9 and a non-standard bolt 10, the first end of the mounting plate 9 is fixed to the horizontal card holder assembly 7, the stud 13 of the non-standard bolt 10 passes through the hole 20 at the second end of the mounting plate 9 and is screwed and fixed to the screw hole of the bottom plate 1, and a limiting assembly is provided between the mounting plate 9 and the stud 13 of the non-standard bolt 10. This arrangement allows the non-standard bolt 10 to be positioned in the hole 20 and will not automatically slip out of the hole 20. More specifically, the stud 13 of the non-standard bolt 10 is not only fastened to the screw hole of the bottom plate 1, but is also locked in the hole 20 by the limiting assembly, thereby achieving the purpose of vibration anti-slip.
[0032] Further, the second end of the mounting plate 9 is provided with a cavity 21, a partition 22 is provided on one side of the cavity 21 close to the hole 20, a cover plate 23 is provided on the other side of the cavity 21 away from the hole 20, and the limiting assembly includes a limiting ring 12 fixed on the stud 13 and a limiting rod 14 and an elastic sleeve 16 movably arranged in the cavity 21, one end of the elastic sleeve 16 is fixed on the inner wall of the cover plate 23, and the other end of the elastic sleeve 16 is fixed to one end of the limiting rod 14, and the other end of the limiting rod 14 passes through the partition 22 and cooperates with the limiting ring 12 to lock. In this way, the stud 13 of the non-standard bolt 10 is locked by the limiting rod 14 and the limiting ring 12, so as to achieve the purpose of vibration prevention.
[0033] Furthermore, the limiting rod 14 is slidably connected to the partition plate 22 , and a limiting groove 13 for cooperating with the limiting rod 14 is formed on the outer wall of the limiting ring 12 .
[0034] Furthermore, an inclined surface 25 that slopes downward is formed at the end of the limiting rod 14 close to the limiting groove 13. With this arrangement, when the stud 13 of the non-standard bolt 10 passes through the hole 20, after the limiting ring 12 contacts the end of the limiting rod 14, under the action of the inclined surface 25, the limiting rod 14 can be pushed aside to compress the elastic sleeve 16. When the limiting rod 14 corresponds to the limiting groove 13, under the rebounding force of the elastic sleeve 16, the limiting rod 14 is pushed to cooperate and be positioned in the limiting groove 13.
[0035] Furthermore, a connecting rod 15 is fixed to one end of the limiting rod 14 close to the cover plate 23. One end of the connecting rod 15 passes through the cover plate 23 and is exposed outside. A handle 24 is provided on the exposed connecting rod 15.

To loosen the non-standard bolt 10, the handle 24 needs to be pulled first to drive the limiting rod 14 to move. After the limiting rod 14 disengages from the limiting groove 13 of the limiting ring 12, the non-standard bolt 10 can be loosened.
[0036] Furthermore, a protective cover 18 is wrapped around the outside of the nut 26 of the non-standard bolt 10, and a positioning component is provided between the protective cover 18 and the nut 26. With this arrangement, by wrapping the protective cover 18 around the outside of the nut 26 of the non-standard bolt 10, the nut 26 of the non-standard bolt 10 can be prevented from rusting.
[0037] Furthermore, the positioning component includes a plurality of card slots 17 provided on the nut 26 and a plurality of elastic balls 19 provided on the inner wall of the protective cover 18. The elastic balls 19 cooperate with the card slots 17 for positioning. With this arrangement, after the elastic balls 19 are compressed and deformed, they are positioned in the card slots 17, so that the protective cover 18 is more firmly positioned and wrapped around the outside of the nut 26 of the non-standard bolt 10.
[0038] Furthermore, a plurality of handles 21 are provided on the front plate 2, and a plurality of heat dissipation air holes are provided on the left plate 5 and the right plate 6. With this arrangement, it is convenient for the loading and unloading of the chassis.
