[0018] (4) In this invention, the contact between the telescopic key and the inner wall of the adjustment slot will limit the support rod in one direction, so that the support rod will not move toward the inner wall of the rotating rod, thereby strengthening the support strength of the main unit and preventing the main unit from being hit when it is too high, causing the main unit to fall over and cause damage to the main unit. This avoids the main unit from tilting or falling during certain operations, thereby reducing the damage to the main unit caused by the equipment falling over or colliding, and ensuring the safety and stability of the equipment.

[0019] (5) In this invention, the sliding pressure rod presses the clamping plate to fit tightly with the main unit, preventing the upper protective shell from separating from the main unit when the main unit accidentally falls over, so that the anti-collision plate on the outer wall of the upper protective shell cannot play a buffering role on the main unit, ensuring that when the main unit tilts or accidentally falls, the upper protective shell and the main unit always remain in a combined state to avoid their separation, ensuring that the upper protective shell can continue to provide buffering for the main unit when the main unit is tilted or unstable, thereby reducing the risk of equipment damage.

[0026] When this embodiment is working: when transporting the host 1, the host 1 needs to be protected to prevent the host 1 from being damaged during transportation. Before transportation, the host 1 needs to be placed on the inner wall of the lower protective shell 3. After the placement is completed, the upper protective shell 2 is placed on the top of the host 1. After the upper protective shell 2 is placed, the card plate 5 is slid along the surface between the upper protective shell 2 and the lower protective shell 3 to clamp the card plate 5 on the outer wall of the host 1. When the card plate 5 moves, it will drive the fixed block 6 to move. The movement of the fixed block 6 will drive the insertion rod 7 to move. The movement of the insertion rod 7 will contact the inner wall of the square groove opened on the surface of another fixed block 6. After the insertion rod 7 is inserted into the square groove, it will contact the inclined surface of the fixed key 8. Then the insertion rod 7 will push the fixed key 8 to slide in the direction away from the fixed block 6. When the square groove on the surface of the insertion rod 7 is in contact with the fixed key When the positions of the two card boards 5 are coincident, the No. 1 spring will drive the fixed key 8 to be inserted into the inner wall of the square groove to limit the insertion rod 7. The fixed key 8 limits the insertion rod 7 so that the two card boards 5 can be fixed to each other. The movement of the card board 5 will drive the fixed plate 11 to move. The movement of the fixed plate 11 will contact the inclined surface of the sliding block 10, and the fixed plate 11 will push the sliding block 10 to move toward the side away from the card board 5. When the two card boards 5 are fixed, the slot on the surface of the sliding block 10 will coincide with the position of the fixed plate 11, and the fixed plate 11 will be driven by the No. 3 spring to slide in the direction of the fixed plate 11, and the fixed plate 11 will be inserted into the inner wall of the slot. When the socket on the surface of the fixed plate 11 coincides with the position of the limit key 12, the No. 2 spring will drive the limit key 12 to move toward the inner wall of the socket. When the limit key 1 2 is inserted into the socket, and the limit key 12 will be limited by the fixing plate 11. After the two card plates 5 are fixed, the upper protective shell 2 and the lower protective shell 3 will also be fixed. This design can complete the initial packaging without additional tools, simplifies the preparation work before transportation, and quickly forms a high-strength protection system before transportation, which significantly improves the overall deformation resistance of the chassis and effectively resists the extrusion or drop impact during transportation. It improves the operation efficiency while ensuring the reliability of protection. When the protective device needs to be disassembled after transportation to the installation location, the staff needs to push the push rod 9 to move toward the inside of the fixed block 6. The movement of the push rod 9 will contact the inclined surface of the fixed key 8, and the push rod 9 will push the fixed key 8 to move away from the insertion rod 7, so the fixed key 8 will limit the insertion rod 7. When the locking cam 11 is released, the fixation between the two card plates 5 will also be released. Pulling the limit key 12 in the direction away from the fixed plate 11 will release the limit between the fixed plate 11 and the limit key 12, and the limit of the sliding block 10 will also be released. Pulling the sliding block 10 downward will release the limit of the sliding block 10 on the fixed plate 11. The sliding block 10 moves downward so that the position of the latch port coincides with the sliding pin 13. Insert the sliding pin 13 into the latch port to limit the sliding block 10 to avoid affecting the removal of the sliding block 10 when the card plate 5 is removed. After the sliding block 10 is fixed, the two card plates 5 can be pulled in the direction away from the host 1 to release the protection of the card plate 5 on the host 1. This design realizes the rapid separation of the structure between the card plate 5 and the host 1.The disassembly time is greatly shortened, and the protective device is quickly and reliably removed. This solves the problem of traditional packaging disassembly requiring destructive disassembly or reliance on tools. While ensuring efficiency, it also maximizes the reusability of the equipment and protective device itself.

After the sliding key 34 releases the contact with the fixed plug plate 33, the support rod 32 will be driven by the No. 5 spring to move in the direction away from the rotating rod 31, and the support rod 32 will contact the opposite side. When the support rod 32 moves, it will drive the telescopic key 35 to move, and the telescopic key 35 moves and contacts the inner wall of the adjustment slot. The contact of the telescopic key 35 with the inner wall of the adjustment slot will limit the support rod 32 in one direction, so that the support rod 32 will not move toward the inner wall of the rotating rod 31, thereby strengthening the supporting strength of the main body 1 and preventing the main body 1 from being hit when it is too high, causing the main body 1 to tip over and cause damage to the main body 1, thereby avoiding the tilting or The movement of the pressing plate 36 will push the clamping plate 37 toward the main body 1, and the movement of the clamping plate 37 will release the obstruction of the sliding pressure rod 39, and the sliding pressure rod 39 will be driven by the No. 6 spring to move in the direction of the clamping plate 37, and the sliding pressure rod 39 will contact the inclined surface of the clamping plate 37, and the sliding pressure rod 39 will press the clamping plate 37 to fit tightly with the main body 1, avoiding the upper protective shell 2 from separating from the main body 1 when the main body 1 accidentally falls, so that the anti-collision plate 4 on the outer wall of the upper protective shell 2 cannot play a buffering effect on the main body 1, ensuring that when the main body 1 tilts or falls accidentally, the upper protective shell 2 and the main body 1 always remain in a combined state, avoiding them from separating, and ensuring that the upper protective shell 2 can continue to provide buffering for the main body 1 when the main body 1 is tilted or unstable, reducing the risk of equipment damage.

[0035] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
