A return spring 558 is arranged on the outer surface of the guiding column 557. Both the first card slot 51 and the second card slot 52 match half of the card block 53 and the convex blocks 54. There is a rotational connection between the first rotating block 552, the protruding part 554, the second rotating block 553 and the end plate 2.

[0039] Please refer to Figure 5, the anti - detachment component 10 includes strip - shaped grooves 101 respectively opened at the outer surfaces of the end - head plate 2 and the side - edge plate 3 near the lower end.

By the side water - blocking plate 63 and the end water - blocking plate 64, it is prevented that water enters from the gap between the lower bottom plate 1 and the end - head plate 2 and the side - edge plate 3. During the use process, due to the fitting characteristic of the waterproof plate 61 and the waterproof strip 62, the gap between the end - head plate 2 and the side - edge plate 3 can be closely fitted, and thus the waterproof effect can be better.

[0041] Please refer to Figure 8-9 , the strengthening structure 11 includes opening grooves 111 respectively opened on the outer surfaces of the end - head plate 2 and the side - edge plate 3. Card holes 112 are opened on the outer surfaces of both the end - head plate 2 and the side - edge plate 3. Threaded holes 113 are respectively opened on the outer surfaces of the end - head plate 2 and the side - edge plate 3 corresponding to the card holes 112. A clamping plate 114 is fixedly connected to the lower outer surface of the top plate 4. A through - hole 115 is opened on the outer surface of the clamping plate 114.

The clamping plate 114 is matched with the two opening grooves 111. The through - hole 115 is matched with the card hole 112. The fixing bolt 116 is matched with the threaded hole 113. The fixing bolt 116 is rotatably connected with both the end - head plate 2 and the side - edge plate 3. The clamping column 117 is matched with both the threaded hole 113 and the card hole 112. The number of sets of threaded holes 113 corresponding to one set of end - head plate 2 and side - edge plate 3 is two groups each. The number of clamping plates 114 is four groups. During use, it is convenient for the installation and disassembly between the top plate 4 and the end - head plate 2 and the side - edge plate 3, and can make the connection between the top plate 4 and the end - head plate 2 and the side - edge plate 3 more stable.

[0042] The working principle of the present invention is as follows: during installation, the user can place the base plate 1 at the position where it needs to be installed, and then pick up the end plate 2 and make the No. 2 snap-fit ​​block 9 at the lower end correspond to the No. 1 snap-fit ​​block 8 in the bottom snap-fit ​​slot 7, while making the side with the end water retaining plate 64 face outward, and press the end plate 2 downward. At this time, the No. 2 snap-fit ​​block 9 corresponds to the position of the No. 1 snap-fit ​​block 8 and is snapped downward. At the same time, the card 103 is snapped into the inside of the bottom snap-fit ​​slot 7 together with the lower end of the end plate 2. At this time, the card 103 remains in a vertical state, and the snap-fit ​​spring 102 will be compressed, completing the installation of the end plate 2 on the base plate 1.

[0043] After the end plate 2 is installed, similarly, the user can vertically insert the No. 2 snap-in block 9 on the side plate 3 into the position corresponding to the No. 1 snap-in block 8. At the same time, the card 103 on the side plate 3 will also maintain the numerical state, and the snap-in spring 102 will be compressed synchronously to complete the installation of the side plate 3 on the base plate 1.

[0044] After completing the installation of the two sets of end panels 2 and side panels 3 in sequence, the user then embeds the entire card block 53 into the groove formed by the No. 1 card slot 51 and the No. 2 card slot 52, so that the adjacent side panels 3 and end panels 2 are tightly connected. At this time, the waterproof strip 62 and the waterproof board 61 will fit tightly.

[0045] Finally, the user inserts the clamping plate 114 on the top plate 4 vertically downward into the groove body formed by the open grooves 111 on the end plate 2 and the side plate 3, and then inserts one end of the fixing bolt 116 with the clamping column 117 into the threaded hole 113, and tightens the fixing bolt 116, so that the fixing bolt 116 is firmly fixed to the outer surface of the end plate 2 and the side plate 3. At this time, one end of the clamping column 117 passes through the through hole 115, and finally one end is embedded in the clamping hole 112, thereby completing the connection between the top plate 4 and the end plate 2 and the side plate 3.

[0046] It should be noted that when disassembly is required, the user can rotate and loosen several sets of fixing bolts 116, and then pull the top plate 4 vertically upward to disassemble the top plate 4;

[0047] Then, grasp the end of the rotating column 556 away from the second rotating block 553, rotate and push downward, the second rotating block 553 drives the rotating shaft 551 to rotate, the rotating shaft 551 drives the first rotating block 552 to rotate, the first rotating block 552 drives the protrusion 554 to rotate, and the protrusion 554 squeezes the convex block 54 to move outward, and the user then pushes the convex block 54 and the clamping block 53 outward through the pulling groove 56, so that the clamping block 53 and the convex block 54 can be pulled outward, and the connection between the side plate 3 and the end plate 2 can be released. When the rotating column 556 is released, the rotating column 556 will return to its original position under the action of the reset spring 558 and the guide column 557 to complete the reset;

[0048] When removing the end plate 2, the user only needs to gently push the card 103 towards the end plate 2 and pull the end plate 2 upwards to separate the second engaging block 9 from the first engaging block 8, and at the same time, the lower end of the end plate 2 and the card 103 are disengaged from the bottom slot 7. Similarly, the disassembly of the side plate 3 from the end plate 2 can be completed.

[0049] It should be noted that the present invention facilitates the assembly of the box body through the mutual connection of multiple groups of mortise and tenon parts, and at the same time, through the setting of structures such as the jacking assembly 55, it facilitates the disassembly of the box body and enhances the waterproof effect of the box body.
