[0007] As a preferred technical solution of the present invention, two mounting plates are symmetrically provided on both sides of the base, and a mounting hole is opened in the middle of the mounting plate, and a handle is provided on one side of the top end of the box body.

[0008] As a preferred technical solution of the present invention, a plurality of connectors are evenly spaced on one side of the plate body, and an arc-shaped groove corresponding to the connector is formed on the bottom of one side of the box body.

[0009] As a preferred technical solution of the present invention, a positioning block is provided on the surface of the plate body, and a positioning groove that engages with the positioning block is provided on one side of the top end of the base.

[0010] As a preferred technical solution of the present invention, the adjustment assembly includes two brackets, the two brackets are rotatably arranged in the middle of the bottom end of the support plate, a rotating plate is rotatably provided between the two brackets, a rotating rod is provided in the middle of the rotating plate, the bottom end of the rotating rod is provided with a gear meshing with the rack plate, the other end of the rack plate is provided with a spring, and one end of the spring is fixedly connected to the inner wall of the base.

[0011] As a preferred technical solution of the present invention, one end of the stretching strip passes through the base and is provided with a pull column, and a surface of the pull column is provided with an anti-slip sleeve.

[0012] As a preferred technical solution of the present invention, the limiting assembly includes a vertical plate, which is fixedly mounted on one side of the top end of the stretching bar, and a limiting block is provided on the top of one side of the stretching bar.

[0014] Compared with the related art, the circuit board protection box provided by the present invention has the following beneficial effects:

[0015] 1. Through the configured adjustment component, the pull column can drive the stretching bar and the rack plate to move horizontally synchronously. This action is transmitted through the gear engaged with the rack plate, driving the rotating rod and the rotating plate to rotate. At the same time, combined with the rotatable bracket and the plug-in plate sliding along the skateboard, the two corresponding plug-in plates can move synchronously toward each other, making it easy to separate the plug-in plate from the slot. In this process, the limit component also plays a key role. As the stretching bar moves, the vertical plate and the limit block on it are synchronously disengaged from the limit slot, thereby releasing the hinged box body so that it can be opened smoothly and the circuit board can be taken out, thereby greatly simplifying the disassembly and installation process of the positioned and installed board body, significantly improving the disassembly and assembly efficiency of the circuit board, and accelerating the work progress.

[0016] 2. Through the combination of the box body and the base, the box body can fully cover the outside of the board body, effectively preventing the circuit board from being damaged during use, thereby ensuring the stable operation and normal function of the circuit board.

[0033] When in use, first place the protective box at a suitable work location, then stretch the pulling column 14, so that the pulling column 14 drives the stretching bar 9 and the rack plate 10 to move synchronously. At this time, the spring 11 is in a stretched state, and then when the stretching bar 9 is stretched and moved, it drives the vertical plate 1201 and the limit block 1202 to move synchronously in the horizontal direction, so that the limit block 1202 originally plugged in is separated from the limit groove at the fixed plate 1203. Then use the handle 20 to open the hinged box body 2, and overlap the hinged box body 2 to the top of the base 1. At this time, the rack plate 10 moves synchronously, and the spring 11 set on one side of the rack plate 10 is stretched, and then drives the gear 804 and the rotating rod through the meshing connection. 803 and the rotating plate 802 rotate synchronously, and combined with the rotatable bracket 801, the two corresponding plugging plates 6 move synchronously on the surface of the slide plate 5. Then, the positioning block 15 is combined with the positioning groove 16 to install the plate body 4 to the top of the partition 3. The plate body 4 is connected and fixed through the connector 17 on the plate body 4 in combination with the relevant wires. Then, the box body 2 is buckled so that the bottom end of the fixed plate 1203 fits the bottom end of the base 1. Then, the pull column 14 is released. Under the support and reset rebound of the spring 11, the stretching bar 9 and the rack plate 10 are reset, and then the gear 804, the rotating rod 803 and the rotating plate 802 are reset synchronously, so that the plugging plate 6 and the slot 13 are tightly plugged into each other and the stability of the plugging is ensured.

[0034] At the same time, when the stretching bar 9 is reset, it simultaneously drives the vertical plate 1201 and the limit block 1202 to move and reset synchronously, so that the limit block 1202 and the limit groove at the fixed plate 1203 are plugged into each other, which makes it easier to buckle the box body 2, thereby achieving comprehensive protection for the circuit board.
