[0019] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0020] Please refer to Figure 1-5 A high and low voltage cabinet protection device comprises a high and low voltage cabinet body 1, and a plurality of elastic ribs 3 and air inlet grooves 11 are arranged on both sides of the high and low voltage cabinet body 1. The elastic ribs 3 are arranged in an arc shape, and the curvature of the elastic ribs 3 changes after being subjected to external force. A protective cover 2 is arranged above the high and low voltage cabinet body 1, and the protective cover 2 is connected to the high and low voltage cabinet body 1 through a buffer mechanism 7, and the buffer mechanism 7 can drive the protective cover 2 to float up and down; when in use, when the two sides of the high and low voltage cabinet body 1 are impacted by external force, the curvature of the elastic ribs 3 changes, and a large amount of impact force can be effectively eliminated through its own elasticity to avoid damage to the internal structure of the high and low voltage cabinet body 1. In addition, when the top of the high and low voltage cabinet body 1 is hit by falling objects, the buffer mechanism 7 can also play a shock-absorbing and buffering role. The overall protection can be carried out in all directions to meet the stable use requirements of the cabinet.
[0021] The two ends of the elastic rib 3 are respectively provided with sliders 31, and the two sides of the high and low voltage cabinet body 1 are provided with slide grooves 32 cooperating with the sliders 31. After the elastic rib 3 is compressed, the slider 31 moves along the slide groove 32; during use, if the elastic rib 3 is deformed after being hit by an external object, the overall length becomes longer instantly, and the slider 31 at the end will move along the slide groove 32. With the elimination of external force and the elasticity of the elastic rib 3 itself, the overall curvature can be restored to its original shape, which can effectively eliminate external impact force.
[0022] The elastic rib 3 is made of high-carbon steel, has good elasticity, can rebound after the impact force is eliminated, and can be reused.
[0023] During use, in order to prevent the elastic ribs 3 from hitting the side walls of the high and low voltage cabinet body when impacted, anti-collision belts 4 are provided on both sides of the high and low voltage cabinet body 1. One side of the anti-collision belt 4 is fixed to the outer wall of the high and low voltage cabinet body 1, and the other side extends toward the elastic rib 3. Under normal circumstances, the elastic rib 3 does not contact the anti-collision belt 4; when the elastic rib 3 is impacted, it bends inwardly and contacts with the anti-collision belt 4 during this process, preventing the elastic rib 3 from directly hitting the outer wall of the high and low voltage cabinet body 1, thereby further improving the protection performance; wherein the anti-collision belt is made of flexible material.
[0024] In this embodiment, the buffer mechanism 7 includes an optical axis 71, a first spring 72, a hinged rod 74, a telescopic rod 75 and a second spring 76. The optical axis 71 is horizontally fixed on the surface of the high and low voltage cabinet body 1. The first spring 72 is arranged on the circumference of the optical axis 71. Slip rings 73 are respectively provided at both ends of the first spring 72. One end of the hinged rod 74 is hinged to the slip ring 73, and the other end is hinged to the inner top wall of the protective cover 2. The telescopic rod 75 is arranged around the optical axis 71. The second spring 76 is arranged around the telescopic rod 75. When the protective cover 2 is pressed and moves downward, the telescopic rod 75 contracts, and at the same time, the first spring 72 is squeezed by the hinged rod 74 and the slip ring 73.
[0025] Specifically, when the protective cover 2 moves downward under pressure, the telescopic rod 75 first contracts and squeezes the second spring 76. At the same time, the two hinged rods 74 push the slip ring to slide along the optical axis, and the two slip rings 73 move toward each other and squeeze the first spring 72. Therefore, the first spring and the second spring are used as the whole to achieve buffering at different angles to eliminate the top impact force and protect the high and low voltage cabinet bodies.
[0026] A column 6 is further provided at the rear of the high and low voltage cabinet body 1 , and the high and low voltage cabinet body 1 is fixed on the column 6 via a U-shaped connecting rod 5 .
[0027] The back of the high and low voltage cabinet body 1 is provided with two connecting pillows 12, and the outer side of the connecting pillow 12 is provided with a vertical semicircular recess 13, and the semicircular recess 13 cooperates with the circumference of the column 6. Connecting holes 14 are provided on both sides of the semicircular recess 13, and the U-shaped connecting rod 5 cooperates with the connecting hole 14. The U-shaped connecting rod 5 passes through the connecting pillow 12 at the connecting hole 14 and extends to the inside of the high and low voltage cabinet body 1, and is tightened by a nut after extension.
[0028] Since the semicircular depression 13 cooperates with the column 6, the contact area can be increased to ensure a stable connection. Then, two sets of U-shaped connecting rods 5 are passed through to achieve overall suspended hanging and fixing, meeting the cabinet usage requirements.
[0029] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
