DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5, in the embodiment of the utility model, a high and low voltage cabinet assembly structure includes a base 1. On both sides of the top of the base 1, side plates 2 are respectively connected through mounting components. The mounting components include fixed blocks 11, moving blocks 12, first springs 13 and fixed rods 14. Rectangular mounting grooves 15 are formed in a rectangular distribution on the top of the base 1. Fixed blocks 11 are welded to the bottom of the side plates 2 and extend into the interior of the mounting grooves 15 and are slidably connected to the mounting grooves 15. On both sides of the base 1, two rectangular grooves 7 are provided. Moving blocks 12 are slidably connected to the interior of the rectangular grooves 7, and the side ends of the moving blocks 12 penetrate through the rectangular grooves 7 and extend to the outside of the base 1. A first spring 13 is fixedly installed between one side of the moving block 12 and the inner wall of the rectangular groove 7. A fixed rod 14 is welded to the side of the moving block 12 away from the first spring 13. Through holes 8 communicating with the mounting grooves 15 and penetrating through the fixed blocks 11 are formed in the inner wall of the rectangular groove 7. The other end of the fixed rod 14 is slidably inserted into the through hole 8.

[0024] During use, the operator first pushes the two moving blocks 12 on one side of the base 1 to slide them in the corresponding rectangular grooves 7 towards the side away from the through hole 8. At this time, the fixed rod 14 moves synchronously under the movement of the moving block 12, and at the same time, the first spring 13 undergoes a compressive deformation. Then, pick up one of the side plates 2 and slide the fixed block 11 at its bottom into the corresponding mounting groove 15. Subsequently, release the force applied to the moving block 12. At this time, the first spring 13 undergoes an elastic reset, thereby driving the moving block 12 to move towards the through hole 8 side, and further enabling the fixed rod 14 to be slidably inserted into the through hole 8, so that the fixed block 11 can be stably fixed in the mounting groove 15, and further enabling the side plate 2 to be assembled and fixed with the base 1. Repeat the above steps for the other side plate 2 for assembly and fixation. The operation is simple and the assembly is convenient.

[0025] On one side of the inner wall of the side plate 2, a back plate 3 is connected through a connecting component. The bottom of the back plate 3 is slidably inserted into the top of the base 1. The connecting component includes a convex groove 21 and a convex plate 22. Convex grooves 21 are symmetrically formed on the side of the inner wall of the side plate 2 close to each other. Convex plates 22 matching the convex grooves 21 are welded to both sides of the back plate 3. The end of the convex plate 22 away from the back plate 3 extends into the convex groove 21 and is slidably connected to the convex groove 21. During use, after the side plate 2 is installed, the operator then picks up the back plate 3 and slides the convex plates 22 welded to both sides of it into the corresponding convex grooves 21. At the same time, the bottom of the back plate 3 is slidably inserted into the top of the base 1, so that the back plate 3 can be stably fixed together with the side plate 2 and the base 1.

[0026] The side of the back panel 3 is connected to the ventilation net 5 through an easy-to-disassemble component. The disassembly component includes a positioning block 31, a positioning rod 32 and a second spring 33. A through slot 9 is provided on the side of the back panel 3. The ventilation net 5 is slidably placed inside the through slot 9. The side of the back panel 3 is rotatably connected to the positioning block 31 on one side of the ventilation net 5 through a bearing. A positioning hole 34 is provided at one end of the positioning block 31 close to the ventilation net 5, and a positioning rod 32 is slidably connected to the inside of the positioning hole 34. One end of the positioning rod 32 passes through the positioning hole 34 and extends to the outside of the positioning block 31 and is welded with a pull block 35. The surface of the positioning rod 32 is sleeved with a second spring 33 located between the pull block 35 and the positioning block 31. One end of the second spring 33 is fixedly connected to the pull block 35, and the other end of the second spring 33 is fixedly connected to the positioning block 31. Four positioning blocks 31 are provided and are respectively located at the four corners of the side of the ventilation net 5.

[0027] When in use, after the operator has installed the back plate 3, the ventilation net 5 is placed in the through groove 9, and then one of the pull blocks 35 is pulled so that the end of the positioning rod 32 reaches the positioning hole 34 opened at one end of the positioning block 31. At the same time, the second spring 33 is stretched and deformed. Then the positioning block 31 is rotated so that the positioning rod 32 is aligned with the positioning hole 34 on the side of the ventilation net 5. Then, the force applied to the pull block 35 is released. At this time, the second spring 33 is elastically reset, so that the end of the positioning rod 32 slides out of the positioning hole 34 at one end of the positioning block 31 through the pull block 35. The locating block 31 is located in the positioning hole 34 on the side of the ventilation net 5, and then the above operation steps are repeated for other positioning blocks 31, so that the ventilation net 5 can be stably fixed in the through slot 9. When the ventilation net 5 needs to be disassembled and cleaned, the operator pulls the pull block 35 in turn to make the positioning rod 32 slide from the positioning hole 34 on one side of the ventilation net 5 to the positioning hole 34 of the positioning block 31, and then rotates the other end of the positioning block 31 to release the interference and fixation on the ventilation net 5, and the ventilation net 5 can be taken out from the through slot 9. The structure is simple, which is convenient for the operator to quickly install or disassemble the ventilation net 5.

[0028] On one side of the side plate 2 away from the back plate 3, a cabinet door 4 is rotatably connected through an assembly component. The assembly component includes a movable block 41, a third spring 42, and a support rod 43. On one side of one side plate 2 away from the back plate 3, an assembly groove 44 is formed. One end of the cabinet door 4 is rotatably connected inside the assembly groove 44. On the side surface of the cabinet door 4, movable grooves 45 are symmetrically formed. Inside the movable grooves 45, movable blocks 41 are slidably connected. On the sides of the movable blocks 41 close to each other, third springs 42 are respectively welded. The other ends of the third springs 42 are welded to the inner walls of the movable grooves 45. On the sides of the movable blocks 41 away from the third springs 42, support rods 43 are welded. Inside the inner wall of the assembly groove 44, a limiting hole 46 is formed that penetrates through the cabinet door 4 and is connected to the movable groove 45. The other end of the support rod 43 extends into the limiting hole 46 and is rotatably connected to the limiting hole 46. On the side ends of the movable blocks 41, push rods 47 are respectively welded that penetrate through the movable grooves 45 and extend to the outside of the cabinet door 4. On the side of the cabinet door 4 away from the movable groove 45, a buckle 48 is rotatably installed. On one side of the other side plate 2, a clamping plate 49 is fixedly installed that matches the buckle 48. The buckle 48 and the clamping plate 49 are snap-connected.

[0029] When in use, when the cabinet door 4 needs to be assembled, the operator picks up the cabinet door 4 and pushes the two push rods 47 closer to each other, thereby driving the movable blocks 41 welded thereto to slide synchronously in the corresponding movable grooves 45. When the movable blocks 41 move, the support rods 43 are driven to move synchronously, and at the same time, the third springs 42 undergo compressive deformation. Then, one end of the cabinet door 4 is placed in the assembly groove 44, and then the force applied to the two push rods 47 is released. At this time, under the elastic reset of the third springs 42, the support rods 43 are driven by the movable blocks 41 to slide and insert into the corresponding limiting holes 46, so that the cabinet door 4 is fixed to one side plate 2. Then, through the cooperation of the buckle 48 and the clamping plate 49, the other side of the cabinet door 4 is fixed to the other side plate 2.

[0030] On the tops of the side plate 2 and the back plate 3, a top plate 6 is fixedly installed through bolts. After the top plate 6 is installed and fixed through bolts, a sealed space can be formed among the base 1, the side plate 2, the back plate 3, and the cabinet door 4.

[0031] Working principle: When in use, first push the moving block 12 on one side of the base 1 to make it move in the rectangular groove 7 away from the through hole 8, thereby driving the fixing rod 14 to move synchronously, and at the same time the first spring 13 is compressed. Then pick up one of the side panels 2 and insert the fixing block 11 into the installation groove 15, release the force applied to the moving block 12, and under the elastic reset of the first spring 13, the moving block 12 drives the fixing rod 14 to slide into the through hole 8, fixing the fixing block 11 and the installation groove 15, thereby assembling and fixing the side panel 2 to the base 1 together, and then repeat this step to assemble the other side panel 2. After the side panel 2 is installed, pick up the back panel 3 and insert the convex plate 22 into the corresponding convex groove 21. At the same time, the bottom of the back panel 3 is plugged into the top of the base 1, so that the back panel 3 can be fixed to the side panel 2 and the base 1 together. Then pick up the ventilation net 5 and place it in the through groove 9, pull one of the pull blocks 35 to drive the end of the positioning rod 32 to the positioning hole 34 at one end of the positioning block 31, and the second spring 33 is Stretch, then rotate the positioning block 31 so that the positioning rod 32 is aligned with the positioning hole 34 on the side of the ventilation net 5, then release the force applied to the pull block 35, and under the elastic reset of the second spring 33, the end of the positioning rod 32 is slid into the positioning hole 34 on the side of the ventilation net 5 through the pull block 35, and then repeat the above operation steps with other positioning blocks 31, thereby stably fixing the ventilation net 5 in the through groove 9, and then pick up the cabinet door 4 and push the push rod 47 closer, so that the support rod 43 is driven synchronously by the movable block 41 When the cabinet door 4 moves, the third spring 42 is compressed, and one end of the cabinet door 4 is placed in the assembly groove 44. Then, the force applied to the push rod 47 is released. At this time, under the elastic reset of the third spring 42, the support rod 43 is driven by the movable block 41 to be inserted into the limiting hole 46, thereby fixing the cabinet door 4 to one of the side panels 2. Then, the other side of the cabinet door 4 is fixed to the other side panel 2 through the cooperation of the buckle 48 and the card plate 49. Finally, the top plate 6 is installed on the top of the side panel 2 and the back panel 3 through bolts.
