[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] According to Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an equipment box with a customizable magnetic tray layout, comprising a box body 1, a magnetic attraction mechanism 2 fixedly connected to the middle of the inner wall of the box body 1 for quickly attracting the tray, an adjustment mechanism 3 fixedly connected to the bottom of the inner wall of the magnetic attraction mechanism 2 for adjusting the internal space of the equipment box, a fixing mechanism 4 fixedly connected to the four corners of the bottom of the box body 1, and a cover plate 5 rotatably connected to the rear top of the box body 1; the magnetic attraction mechanism 2 includes a magnet 201, which is fixedly connected to the bottom of the inner wall of the box body 1, and the top of the outer wall of the magnet 201 is fixedly connected to the top of the box body 1. A fixed frame 202 is fixedly connected to the part. A baffle 203 is slidably connected to the middle of the inner wall of the fixed frame 202. Multiple partitions 204 are fixedly connected to the outer wall of the baffle 203. A folding assembly 205 is fixedly connected to the outer wall of the magnet 201. The folding assembly 205 includes a fixing bolt 2051. The fixing bolt 2051 is slidably connected to the outer wall of the fixed frame 202. A fixing plate 2052 is rotatably connected to one side of the outer wall of the fixing bolt 2051. A fixing groove 2053 is opened at the bottom of the outer wall of the fixing plate 2052. A track 2054 is fixedly connected to one side of the inner wall of the fixing groove 2053.

[0040] Specifically, magnet 201 is fixed to the bottom of the inner wall of the housing 1, generating an adsorption force. Magnetic track 2054 contains magnetic material, forming a magnetic coupling with magnet 201, allowing the tray to quickly adhere to the bottom of the housing 1, providing a stable vertical adsorption force and preventing shaking. This allows for quick installation and removal of the tray, improving operational efficiency. Baffle 203 is slidably connected to the middle of the fixing frame 202, limiting the lateral position of the tray. Divider 204 surrounds baffle 203, dividing the interior of the housing 1 into multiple areas to accommodate equipment of different sizes. After the tray is embedded in magnetic track 2054, pushing baffle 203 adjusts its position, forming a physical separation through partition 204. Combined with magnetic fixation, this achieves dual stability. Magnetic track 2054 is installed on the main body of the equipment housing. Inside the slot, it can slide freely. When storing large equipment, the tray spacing can be increased or some trays can be removed to adapt to the equipment size. The fixing bolt 2051 is slidably connected to the fixing frame 202. The fixing plate 2052 can be unfolded or retracted. The fixing plate 2052 is magnetically connected to the magnet 201 through the track 2054 to form an extended magnetic surface on the side wall of the box 1, which is used to attract side-hanging trays or tool accessories. The fixing bolt 2051 slides to the storage position to save space. The connecting block is fixed to the contact surface of the adjacent magnetic track 2054 and locked by the fixing bolt 401 to connect multiple magnetic tracks 2054 into a whole. The end of the tray body is fixed to the magnetic track 2054 by a buckle. It can be quickly installed and removed without tools, making it easy to replace trays of different sizes.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The adjustment mechanism 3 includes a support column 301, which is fixedly connected to the left and right sides of the outer wall of the magnet 201. A movable frame 302 is slidably connected to the middle of the inner wall of each of the two support columns 301. Telescopic rods 303 are rotatably connected to the left and right sides of the outer wall of the movable frame 302. A suction cup 304 is fixedly connected to one end of the outer wall of the multiple telescopic rods 303. The suction cup 304 is fixedly connected to the bottom of the outer wall of the fixed frame 202. A lifting assembly 305 is fixedly connected to the top of the inner wall of the right support column 301. The lifting assembly 305 includes a motor 3051, which is fixedly connected to the top right side of the support column 301. A rotating shaft 3052 is fixedly connected to the output end of the motor 3051. A rope 3053 is fixedly connected to one side of the outer wall of the rotating shaft 3052. The other end of the rope 3053 is fixedly connected to one side of the outer wall of the movable frame 302.

[0042] Specifically, after the motor 3051 starts, it drives the rotating shaft 3052 to rotate, controls the extension and retraction of the rope 3053, and causes the movable frame 302 to slide up and down within the support column 301. The swing of the movable frame 302 drives the suction cup 304 to rise and fall. Through the adsorption of the magnet 201, the height of the fixed frame 202 is adjusted. This mechanism achieves the adjustment and fixation of the target object's position through the drive of the motor 3051, the control of the rope 3053, and the angle change of the telescopic rod 303.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The fixing mechanism 4 includes bolts 401, which are threadedly connected to the four corners of the bottom of the box 1. The bottom of the outer wall of the multiple bolts 401 is fixedly connected to the fixing legs 402. The outer wall of the bolts 401 is fixedly connected to one side of the outer wall of the bolts 401. The buffer assembly 403 includes nuts 4031, which are threadedly connected to the top of the outer wall of the bolts 401. The bottom of the outer wall of the nuts 4031 is fixedly connected to the springs 4032. The left and right sides of the outer wall of the cover plate 5 are fixedly connected to the rotating shafts 6. The inner wall of the rotating shafts 6 is rotatably connected to the adjacent side. The front side of the outer wall of the cover plate 5 is rotatably connected to the buckle 8. The front side of the outer wall of the box 1 is fixedly connected to the fixing ring 9.

[0044] Specifically, the device uses bolts 401 to install the fixing legs 402 at the four corners of the bottom of the box 1 for support. The bolts 401 are in the buffer assembly 403. After the nuts 4031 are tightened, the springs 4032 provide elastic buffering to the bottom of the box 1. The cover 5 is opened and closed by rotating the left and right pivots 6 and the handles 7. The front buckle 8 is fastened and fixed to the fixing ring 9 of the box 1, forming a box 1 structure that is portable and has a buffering function.

[0045] Working principle: The magnet 201 is fixed to the bottom of the inner wall of the box 1, generating an adsorption force through its own magnetism. The magnetic track 2054 is located in the fixing groove 2053 of the folding assembly 205. It has built-in magnetic material and is connected to the magnet 201, allowing the pallet body to be quickly adsorbed to the bottom of the box 1 through the magnetic track 2054 embedded at the bottom, providing a stable vertical adsorption force and preventing the pallet from shaking up and down during transportation. The pallet can be quickly installed or removed without additional tools, improving operational efficiency. The baffle 203 is slidably connected to the middle of the fixing frame 202 and can move horizontally to limit the lateral position of the pallet. The partition 204 surrounds the baffle 203, dividing the interior of the box 1 into multiple independent areas to accommodate the classification and storage of equipment of different sizes. After the tray is embedded in the magnetic track 2054, the baffle 203 is pushed to adjust it to a suitable position, forming a physical separation through the partition 204. Combined with magnetic fixation, the magnetic track 2054 is installed in the mounting groove of the equipment box body and can slide freely horizontally. When storing large equipment, the tray spacing can be increased or some trays can be removed to adapt to the equipment size. The fixing bolt 2051 is slidably connected to the fixing frame 202, allowing the fixing plate 2052 to be expanded or retracted around the box body 1. The fixing plate 2052 is magnetically connected to the magnet 201 through the track 2054, forming an extended magnetic surface on the side wall of the box body 1 for adsorbing side-hanging trays or tool accessories. When the fixing bolt 2051 slides to the storage position, the fixing plate 2052 fits against the inner wall of the box body 1, saving space. The connecting block is fixed to the contact surface of adjacent magnetic tracks 2054 and locked with fixing bolts 401, connecting multiple magnetic tracks 2054 into a whole. When the pallet carries equipment, gravity is transferred to the magnetic tracks 2054 through the pallet. The connecting block is connected to the track 2054 with bolts 401 to prevent displacement of individual tracks 2054 due to uneven force, ensuring the stability of the overall structure. The end of the pallet body is fixed to the magnetic track 2054 with buckles, which can be quickly loaded and unloaded without tools, and it is convenient to replace different specifications of pallets according to the size of the equipment. The fixing mechanism 4 at the four corners of the bottom of the box 1 has rubber feet and bolts 401, and holes for connecting transport vehicles. Physical fixation further eliminates the risk of displacement during transportation. The cover plate 5 is closed by rotating through the rear hinge. Meanwhile, the cover plate 5 itself presses down on the pallet, enhancing stability during transportation. Select the appropriate pallet according to the equipment size, align the magnetic track 2054 at the bottom of the pallet with the mounting groove of the box 1, and gently press it to attract the magnet 201; slide adjacent magnetic tracks 2054 to adjust the spacing, and fix multiple tracks 2054 with connecting blocks and bolts 401; push the baffle 203 to limit the lateral position of the pallet, and the partition 204 separates different equipment areas. If it is necessary to store side-mounted equipment, unfold the fixing plate 2052 of the folding component 205 so that the track 2054 is attracted to the side of the magnet 201, install the side pallet, close the cover plate 5 and lock it, and fix the box 1 to the transport carrier through the bottom fixing mechanism 4. The magnetic attraction and mechanical connection provide double protection to prevent the pallet from shifting.

[0046] After the motor 3051 at the top of the right support column 301 is started, it drives the rotating shaft 3052 at the output end to rotate, thereby winding or releasing the rope 3053. The rope 3053 is connected to the movable frame 302. The forward and reverse rotation of the motor 3051 controls the winding and releasing of the rope 3053, driving the movable frame 302 to slide up and down in the inner wall of the left and right support columns 301. When the movable frame 302 slides, the telescopic rods 303 on its left and right sides swing accordingly, driving the suction cups 304 at the end to rise and fall synchronously. The suction cups 304 are fixed to the bottom of the fixed frame 202. The height of the fixed frame 202 is adjusted by raising and lowering, and with the adsorption of the magnet 201, the movement is achieved. The working principle of the adjustment mechanism 3 for adjusting and fixing the position of the target object is as follows: the motor 3051 drives the rotating shaft 3052 at the output end to rotate, winding or releasing the rope 3053, thereby driving the moving frame 302 to slide up and down within the support column 301; the moving frame 302 is connected to the fixed frame 202 through the telescopic rod 303 and the suction cup 304, and its lifting action is converted into the horizontal height adjustment of the fixed frame 202 by the angle change of the telescopic rod 303; the magnet 201 is attached to the fixed surface to provide stable support, and the suction cup 304 ensures a firm connection with the fixed frame 202, ultimately realizing the height adjustment function of the fixed frame 202 and related components.
