Square storage slots 4 are provided on the four outer walls of the support column 1. A fixing plate 5 is hinged to the top of the storage slot 4 via hinges. The fixing plate 5 and the support column 1 are fixed together by a snap-fit ​​mechanism to fix and limit the unfolding opening of the fixing plate 5. By hinged a set of support base plates 2 to the lower part of the four outer walls of the support column 1 and using a locking mechanism to secure the support base plates 2 and the support column 1, the device achieves a fixed and limited function. The supporting columns 1 are locked together, and a fixed plate 5 is hinged inside the storage slot 4 and a snap-fit ​​mechanism is used to snap and limit the fixed plate 5, so that the environmentally friendly laboratory air environment monitoring device can be easily folded and stored. The end of the fixed plate 5 away from the supporting columns 1 is provided with a telescopic adjustment mechanism, and the end of the telescopic adjustment mechanism away from the fixed plate 5 is connected to a movable plate 6. The telescopic adjustment mechanism drives the movable plate 6 to move horizontally. An air detector 7 for monitoring the air environment inside the environmentally friendly laboratory is placed on the top of the movable plate 6, and the air detector 7 is clamped and fixed to the top of the movable plate 6 by a clamping mechanism. By placing the air detector 7 on the top of the movable plate 6 and using the clamping mechanism to clamp and fix the air detector 7, the air detector 7 can be easily assembled and disassembled.

[0024] The locking and docking mechanism includes a first semicircular threaded post 8 and a second semicircular threaded post 9. The first semicircular threaded post 8 and the second semicircular threaded post 9 are mutually adapted and can be spliced ​​together to form a complete threaded post. The first semicircular threaded post 8 is welded and fixed to the bottom end of the support base plate 2, and the second semicircular threaded post 9 is welded and fixed to the bottom end of the support square post 1 and is adapted to the position of the first semicircular threaded post 8. The first semicircular threaded post 8 and the second semicircular threaded post 9 are threaded together with a threaded connecting ring 10. When the support base plate 2 is horizontally unfolded, the first semicircular threaded post 8 and the second semicircular threaded post 9 are docked, and then the threaded connecting ring 10 is threaded onto the first semicircular threaded post 8 and the second semicircular threaded post 9, thereby realizing the fixed locking between the support base plate 2 and the support square post 1.

[0025] The locking mechanism includes a lifting frame 11 and an insert plate 12. The lifting frame 11 is designed in the shape of a U-shape and is slidably connected to the top of the fixed plate 5. The insert plate 12 is fixed to the outer wall of the supporting square column 1. The lifting frame 11 has a through groove that matches the insert plate 12 so that the insert plate 12 can be inserted. A T-shaped slider 13 is fixed to the bottom of the lifting frame 11. A T-shaped groove 14 is opened at the top of the fixed plate 5, and the T-shaped groove 14 matches the T-shaped slider 13. The T-shaped slider 13 is slidably connected in the T-shaped groove 14 to realize the sliding connection of the lifting frame 11 at the top of the fixed plate 5. When the fixed plate 5 is horizontally unfolded, the lifting frame 11 is slidably sleeved on the insert plate 12 to realize the limiting and fixing of the fixed plate 5.

[0026] The telescopic adjustment mechanism includes a threaded tube 15 and a threaded rod 16. The threaded tube 15 is rotatably connected to the fixed plate 5 via a bearing. The end of the threaded rod 16 away from the fixed plate 5 is fixedly connected to the movable plate 6. The side of the threaded rod 16 away from the movable plate 6 is threadedly connected to the inside of the threaded tube 15. A limiting mechanism is provided between the fixed plate 5 and the movable plate 6. By rotating the threaded tube 15, the threaded rod 16 is driven to extend or retract inside the threaded tube 15. During the movement of the threaded rod 16, the movable plate 6 is moved synchronously.

[0027] The limiting mechanism includes a limiting tube 17 and a limiting rod 18. The limiting tube 17 is provided in two sets and is symmetrically fixed on the movable plate 6. The limiting rod 18 is provided in two sets and is symmetrically fixed on the fixed plate 5. The end of the limiting rod 18 away from the movable plate 6 is slidably connected to the inside of the limiting tube 17. The limiting tube 17 and the limiting rod 18 cooperate to limit the distance between the fixed plate 5 and the movable plate 6.

[0028] The clamping mechanism includes a knob 19, a bidirectional lead screw 20, and threaded blocks 21. The bidirectional lead screw 20 is rotatably connected to the inside of the movable plate 6 via bearings. The end of the bidirectional lead screw 20 away from the fixed plate 5 passes through the movable plate 6 via bearings and is fixedly connected to the knob 19. There are two sets of threaded blocks 21, which are threaded onto both sides of the bidirectional lead screw 20 with opposite threading directions. The top of the threaded blocks 21 slides through to the top of the movable plate 6 and is fixed with an arc-shaped clamping plate 22. The top of the movable plate 6 has symmetrical through slots that fit the threaded blocks 21. By rotating the knob 19, the bidirectional lead screw 20 is driven to rotate, causing the threaded blocks 21 threaded onto both sides of the bidirectional lead screw 20 to move the arc-shaped clamping plate 22 towards each other until the air detector 7 at the top of the movable plate 6 is clamped and fixed. The top of the supporting column 1 is fixed with an indicator light 23 by bolts. The air detector 7 is connected to the PLC control system of the device and is used to drive the indicator light 23 to flash when the air environment is found to be unqualified, so as to alert the relevant laboratory personnel.

[0029] In actual use, the environmentally friendly laboratory air environment monitoring device is first moved into the environmentally friendly laboratory. The support base plate 2, which is hinged to the four outer walls of the support column 1, is first unfolded horizontally, and the support base plate 2 and the support column 1 are locked and fixed using the locking and docking mechanism. The four sets of universal wheels 3 at the bottom of the support base plate 2 provide support for the support column 1, and at the same time make the support column 1 easy to move and transfer. Then, the fixed plate 5, which is hinged in the storage slot 4, is unfolded horizontally, and the unfolded fixed plate 5 is locked and limited using the snap-fit ​​mechanism. Then, the air detector 7 is clamped and fixed to the top of the movable plate 6 using the clamping mechanism. Then, the air detector 7 is turned on to monitor the air environment inside the laboratory. During the monitoring process, the telescopic adjustment mechanism is used to drive the air detector 7 at the top of the movable plate 6 to move horizontally until the air detector 7 moves horizontally to the corresponding position.

[0030] When not in use, first release the clamping mechanism from the air detector 7, then remove the air detector 7 directly from the top of the movable plate 6 to complete the easy disassembly of the air detector 7. Next, release the locking mechanism from the locking limit of the fixed plate 5, and fold the fixed plate 5 together with the movable plate 6 into the storage slot 4. Then, release the locking and docking mechanism from the locking and fixing between the support base plate 2 and the support column 1, and fold the support base plate 2 upwards at ninety degrees until it fits against the support column 1 to complete the entire folding and storage, making the environmentally friendly laboratory air environment monitoring device easy to store and transfer.
