The monitoring test bench consists of a desktop 1, a mounting platform 2 and a camera 5, and a limiting mechanism is provided on the two telescopic rods 4; the telescopic rods 4 can be limited by setting the limiting mechanism.

[0033] The limiting mechanism includes a limiting bolt 10 . A threaded hole 9 is formed in the lower half of the telescopic rod 4 . The limiting bolt 10 is screwed into the threaded hole 9 . One end of the limiting bolt 10 passes through one side of the mounting platform 2 and is fixedly mounted with a limiting knob 11 .

[0034] When in use, by turning the limit knob 11, the limit knob 11 will drive the limit bolt 10 to rotate as well, thereby releasing the restriction on the telescopic rod 4. At this time, the telescopic rod 4 can be stretched to adjust the height of the camera 5, and the telescopic rod 4 can also be compressed to hide the camera 5 in the installation slot 3.

[0035] Reference Figure 1 and Figure 3 The top outer wall of the mounting platform 2 is fixedly mounted with a mounting box 6, and the bottom inner wall of the mounting box 6 is symmetrically slidably mounted with two rack plates 12, and the bottom inner wall of the mounting box 6 is rotatably mounted with a gear 13, and the two rack plates 12 can be driven to approach or move away from each other by setting the gear 13, and the gear 13 is respectively meshed with the two rack plates 12, and the outer walls of the two rack plates 12 on the side away from each other are fixedly mounted with a protective cover 16, and the protective cover 16 can play a protective role, and a driving mechanism is provided on the gear 13. The driving mechanism can play a role in driving the gear 13 to rotate.

[0036] Reference Figure 3 The driving mechanism includes a rotating column 14, which is fixedly mounted on one end of the top of the gear 13, and a fixed knob 15 is fixedly mounted on one end of the top of the rotating column 14. By rotating the fixed knob 15, the fixed knob 15 rotates, thereby driving the rotating column 14 and the gear 13 to rotate.

[0037] Reference Figure 3 and Figure 4 The top outer wall of the installation box 6 is provided with a rotation hole 18, and the rotating column 14 is rotatably installed in the rotation hole 18. By setting the rotation hole 18, the rotating column 14 can be rotatably installed inside, which plays a role of auxiliary installation.

By providing the sliding grooves 17, the rack plates 12 can be slidably installed therein, which plays a role in auxiliary installation.

[0039] Reference Figure 1 The protective cover 16 is the same size as the mounting groove 3. By setting the protective cover 16 to be the same size as the mounting groove 3, a shielding effect can be achieved.

[0040] Reference Figure 1 The top outer wall of the mounting box 6 is fixedly mounted with a limit screw 7, and a limit plate 8 is screwed on the limit screw 7. By rotating the limit plate 8, the limit plate 8 rotates so that the restriction on the fixed knob 15 can be released, and the fixed knob 15 can be limited.

[0042] The implementation principle of the present application is as follows: when in use, firstly, by rotating the limit knob 11, the limit knob 11 rotates, thereby driving the limit bolt 10 to rotate as well, thereby releasing the restriction on the telescopic rod 4. At this time, the telescopic rod 4 can be stretched to adjust the height of the camera 5, and the telescopic rod 4 can also be compressed to hide the camera 5 in the installation slot 3;

[0043] By rotating the limit plate 8, the limit plate 8 rotates to release the restriction on the fixed knob 15. At this time, the fixed knob 15 can be rotated. The rotation of the fixed knob 15 will drive the rotating column 14 and the gear 13 to rotate. The rotation of the gear 13 will drive the two rack plates 12 and the two protective covers 16 to move away from each other. The two protective covers 16 move away from each other to cover the two installation slots 3, thereby preventing the laboratory from using chemical products such as acid when there is no examination, so that the camera 5 will not be corroded by the acid, thereby playing a protective role.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
