DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0025] See also Figure 1-7 The present application provides a laboratory hazardous chemical storage and control device, including an outer cabinet device 10, an inner cabinet 20 is installed in the outer cabinet device 10, and guide rails 30 are installed on the side walls of both ends of the inner cabinet 20, and sliders 40 are slidably connected in the guide rails 30 on both sides. A same bracket 50 for carrying items is connected between the sliders 40 on both sides, and locking parts 60 are slidably connected to the sliders 40 on both sides. Specifically, laboratory hazardous chemicals are stored in the inner cabinet 20 and are controlled by the existing outer cabinet device 10. Several brackets 50 and sliders 40 on both sides are provided, and the sliders 40 can slide in the guide rails 30 to drive the brackets 50 to move up and down in the inner cabinet 20, so that the distance between several brackets 50 can be adjusted to facilitate the storage of hazardous chemicals of different heights.

[0026] See Figure 4The guide rail 30 is U-shaped, and the slider 40 is slidably arranged in the guide rail 30. A through-hole 310 is opened on the side wall of one end of the guide rail 30, and the locking member 60 passes through the through-hole 310. The locking member 60 includes a sliding rod 610 slidably connected to the slider 40. The sliding rod 610 passes through the through-hole 310, and a limit block 620 is fixedly sleeved thereon. The limit block 620 is clamped with the through-hole 310. When set, the sliding rod 610 can slide on the slider 40, so that the sliding rod 610 drives the limit block 620 to move, so that the limit block 620 can drive out of the through-hole 310 or drive into the through-hole 310, so as to support the slider 40 or release the support for the slider 40, thereby facilitating the adjustment of the position of the bracket 50.

[0027] See Figure 6 A chamber 410 is provided in the slider 40, and the slide rod 610 slides through one end side wall of the chamber 410, and a connecting block 70 is fixedly installed at one end thereof. The connecting block 70 is slidably arranged in the chamber 410, and the same spring 710 is connected between the connecting block 70 and the side wall of the chamber 410. In the specific setting, the spring 710 is provided in the chamber 410 to achieve the purpose of limiting the slide rod 610, and then when the slide rod 610 is pulled outward, the slide rod 610 pulls the spring 710 through the connecting block 70, so that when the slide rod 610 is released, the slide rod 610 can be automatically reset, which is convenient for use.

[0028] See Figure 7 A plurality of limit grooves 320 are provided on the side wall of the through-opening 310, and the plurality of limit grooves 320 are arranged at equal intervals. The limit block 620 is inserted into one of the limit grooves 320. Specifically, the limit block 620 can be switched among the plurality of limit grooves 320 to adjust the position of the bracket 50. Further, the sliding rod 610 is pulled to make the limit block 620 move out of the limit groove 320, and then the position of the limit block 620 can be adjusted.

[0029] See Figure 4 The two slide rods 610 are connected by the same connecting rod 80. It should be noted that by pulling the connecting rod 80, the two slide rods 610 can move synchronously, which is convenient for operation. Furthermore, the connecting rod 80 is U-shaped and is located below the bracket 50.

[0030] See Figure 4 and 5 The bracket 50 includes a U-shaped plate 510, and U-shaped rails 520 are fixedly installed on the inner walls at both ends of the U-shaped plate 510. The same item rack 530 is slidably connected between the two U-shaped rails 520, and the two sliders 40 are fixedly connected to the outer walls at both ends of the U-shaped plate 510. Specifically, U-shaped rails 520 are installed on the inner walls on both sides of the U-shaped plate 510, so that the item rack 530 moves along the U-shaped rails 520 to achieve the purpose of pulling out the item rack 530, thereby facilitating the placement of hazardous chemicals.

[0031] See Figure 5 The item rack 530 includes a carrying plate 5310, which is U-shaped and has fixed blocks 5320 fixedly installed on its two end side walls. The two fixed blocks 5320 are respectively slidably arranged in the two U-shaped rails 520. A limiting plate 5330 is fixedly installed on the inner wall of the carrying plate 5310. The limiting plate 5330 is provided with a plurality of limiting holes 5340. When set, the bottled hazardous chemicals are placed on the carrying plate 5310 through the limiting holes 5340, and the limiting plates 5330 achieve the purpose of limiting the hazardous chemicals to prevent them from moving.

[0032] When using this laboratory hazardous chemicals storage and control device: open the inner cabinet 20, adjust the position of the bracket 50 according to the height of the bottled hazardous chemicals, specifically, pull the connecting rod 80 to make the two sliding rods 610 move synchronously, so that the two limit blocks 620 are driven out of the two limit slots 320, and then move the bracket 50, adjust the position between the limit blocks 620 and the limit slots 320 to adjust the height of the bracket 50, after the height of the bracket 50 is adjusted, insert the limit blocks 620 into the corresponding limit slots 320, and then pull the supporting plate 5310 to make the fixed block 5320 slide in the U-shaped rail 520 to pull the supporting plate 5310 outward, so as to facilitate the hazardous chemicals to be placed on the supporting plate 5310 through the limit holes 5340. After the placement is completed, push the supporting plate 5310 to reset.

[0033] It should be noted that the specific model and specifications of the external cabinet device 10 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
