Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6 The utility model provides a technical solution: a storage cabinet for storing hazardous chemicals for chemical analysis, comprising a work plate 1, a cabinet body 2 is fixed on the top surface of the work plate 1, a cabinet door 3 hinged to the front surface of the cabinet body 2 is embedded, and two adjustment plates 4 symmetrical to each other and slidably connected to the inner top surface of the cabinet body 2 are arranged inside the cabinet body 2, and also include:

[0029] Two adjusting mechanisms 7 are respectively arranged on the left and right outer walls of the cabinet 2. The adjusting mechanism 7 includes a rotating drum 71 which is rotatably connected to the outer wall on the same side of the cabinet 2 and has an internal thread on the inner wall, a screw 72 threadedly connected to the rotating drum 71, a rotating rod 74 coaxially fixed on the outer wall of the rotating drum 71 away from the cabinet 2, two gears 75 located above the working plate 1 and used to drive the rotating rod 74 to rotate, and a motor 76 installed on the outer wall on the same side of the cabinet 2 and used to drive the two gears 75 to rotate. The two gears 75 are meshed with each other, and the opposite back surfaces of the two adjusting plates 4 are fixed with connecting columns 73 coaxially fixed with the screw 72 on the same side. By arranging the working plate 1, the cabinet 2, the cabinet door 3 and the two adjusting plates 4, hazardous chemicals can be stored. The positions of the two adjusting plates 4 can be adjusted by the two adjusting mechanisms 7, thereby adjusting the storage space inside the cabinet 2, thereby facilitating the storage of hazardous chemicals of different types or quantities.

[0030] In this embodiment, the adjustment mechanism 7 also includes a rotating shaft 77 coaxially connected to the output shaft of the motor 76, and two same-side gears 75 are coaxially fixed on the outer walls of the same-side rotating shaft 77 and the same-side rotating rod 74, respectively, which can smoothly drive the two gears 75 to rotate, and then smoothly drive the rotating drum 71 to rotate.

[0031] In addition, the inner top surface of the cabinet 2 is provided with two guide grooves, and the top surface of the adjustment plate 4 is fixed with two guide blocks 5 slidably connected to the guide grooves on the same side of the inner top surface of the cabinet 2, which can guide the movement of the two adjustment plates 4.

[0032] Furthermore, a plurality of support columns 8 arranged in a matrix are fixed to the bottom end of the working plate 1, a support plate 9 is fixed to the bottom end of the support column 8, and a universal wheel 10 is installed at the bottom end of the support plate 9. It should be added that the universal wheel 10 is a prior art and has a built-in locking structure, which can enable the entire device to have the function of movement.

[0033] Specifically, push-pull rods 6 are fixed to the left and right surfaces of the working plate 1, and the push-pull rods 6 are U-shaped, which, together with a plurality of universal wheels 10, facilitate pushing and pulling of the entire device.

[0034] It is worth noting that the adjustment mechanism 7 also includes a protection box 78 fixed on the outer wall on the same side of the cabinet 2, the motor 76 is located inside the protection box 78 on the same side, and the rotating shaft 77 passes through the outer wall of the protection box 78 on the same side away from the cabinet 2, which can protect the motor 76 and thus extend the service life of the motor 76.

[0035] It is worth mentioning that the longitudinal cross-sectional shape of the guide groove on the inner top surface of the cabinet body 2 is I-shaped, and the shape of the guide block 5 is I-shaped which is compatible with the shape of the guide groove on the inner top surface of the cabinet body 2, which can make the connection between the guide block 5 and the guide groove on the same side of the inner top surface of the cabinet body 2 tighter, thereby indirectly making the adjustment plate 4 more stable during movement.

[0036] It is worth emphasizing that the distance between the protection box 78 and the rotating drum 71 on the same side is 2-5cm, and the distance between the protection box 78 and the gear 75 on the same side is 3-7cm. In this article, the distance between the protection box 78 and the rotating drum 71 on the same side is preferably 3cm, and the distance between the protection box 78 and the gear 75 on the same side is preferably 5cm, so that the gear 75 and the rotating drum 71 can rotate smoothly.

[0037] Among them, the motor 76 involved in this embodiment is a prior art, and its structure and working principle are well known to those skilled in the art, and will not be elaborated here.

[0038] The rotation of the shaft 77 drives the coaxial gear 75 fixed thereto on the same side to rotate, and the rotation of the gear 75 drives another gear 75 meshing with it to rotate, and the rotation of the other gear 75 drives the coaxial rotating rod 74 fixed thereto on the same side to rotate, and the rotation of the rotating rod 74 drives the coaxial rotating drum 71 fixed thereto on the same side to rotate, and the rotation of the rotating drum 71 drives the screw 72 threadedly connected thereto to move, and the movement of the screw 72 drives the connecting column 73 fixed thereto on the same axis to move, and the movement of the connecting column 73 drives the left adjusting plate 4 fixed thereto to move, and the adjusting plate 4 moves under the guidance of the two coaxial guide blocks 5 and the two guide grooves on the inner top surface of the cabinet 2, and when the distance between the adjusting plate 4 and the left inner wall of the working plate 1 is appropriate, the motor 76 on the left side is turned off by the external PLC;

[0039] Then, the right motor 76 is started through the external PLC. Similarly, the output shaft of the right motor 76 rotates to indirectly drive the right adjustment plate 4 to move. When the distance between the right adjustment plate 4 and the left adjustment plate 4 and the right inner wall of the working plate 1 is appropriate, the right motor 76 is turned off through the external PLC, thereby completing the work of adjusting the internal storage space of the cabinet 2.
