Technical Field

[0001] This utility model relates to the field of laboratory cabinet technology, and in particular to a laboratory cabinet with odor prevention function. Background Technology

[0002] After prolonged use, laboratory cabinets can release odors from chemicals and other materials. These odors are often irritating and can cause discomfort to laboratory personnel, potentially harming their health. For example, the odors released by some volatile organic solvents can cause headaches, dizziness, and nausea with prolonged inhalation. Furthermore, odors can interfere with experimental results, especially in experiments where odor sensitivity is a concern, affecting the accuracy and reliability of the experiment. To address this technical problem, this application proposes a laboratory cabinet with odor-proof design. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a laboratory cabinet with odor prevention. By placing adsorbents such as activated carbon and bamboo charcoal inside the storage shell, odor molecules are absorbed. When the adsorbent needs to be replaced after prolonged use, the gripping block drives the limiting insert to slide, releasing the fixation of the storage shell and allowing the storage shell to be pulled out, thus making the replacement of the adsorbent faster.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A laboratory cabinet with odor prevention features includes a cabinet with three placement panels fixedly connected to its inner wall and four support frames fixedly connected to its bottom. Each support frame has pulleys rotatably connected to its inner wall, with the front and rear ends of the pulleys connected by limiting components to limit their movement. Three placement blocks are fixedly connected to the inner wall of the cabinet, and three limiting slots are provided on the right side of the cabinet. A storage shell is inserted into the right side of each placement block, and the front of the storage shell is connected to the inner wall of the limiting slots via a fixing component to secure the storage shell.

[0006] Furthermore, the limiting component includes a first gear fixedly connected to the front and rear ends of the pulley, a second gear meshing with the top side of the outer wall of the first gear, a limiting rack slidably connected to the inner wall of the support frame, and the right side of the limiting rack meshing with the left side of the second gear.

[0007] Furthermore, four third springs are fixedly connected to the left side of the inner wall of the support frame, the right end of the third springs is fixedly connected to the left side of the limiting rack, and a limiting screw is threadedly connected to the left side of the support frame, the right end of the limiting screw abuts against the left side of the limiting rack.

[0008] Furthermore, the fixing component includes a limiting block that is slidably connected to the inner wall of the limiting groove, the rear side of the limiting block being inserted into the front side of the storage shell, and four second springs being provided inside the limiting groove.

[0009] Furthermore, one end of the second spring is fixedly connected to the front side of the inner wall of the limiting groove, and the other end of the second spring is fixedly connected to the front side of the limiting block. A gripping block is fixedly connected to the right side of the limiting block.

[0010] Furthermore, at least twenty limiting boxes are fixedly connected to the top of the placement plate, and two first springs are fixedly connected to the left and right sides of the inner wall of each limiting box. A limiting clamp is fixedly connected to the end of each first spring on the left and right sides that is close to each other.

[0011] Furthermore, an anti-slip pad is fixedly connected to the top of the placement plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, by placing adsorbents such as activated carbon and bamboo charcoal inside the storage shell, odor molecules are absorbed. When the adsorbent needs to be replaced after a long period of use, the gripping block is used to move the limiting insert block to release the fixation of the storage shell and pull out the storage shell, thereby making the replacement of the adsorbent faster.

[0014] 2. In this utility model, by tightening the limiting screw to release the fixing of the limiting rack, the pulley can be rotated to transfer the cabinet. After the cabinet is transferred, tighten the limiting screw to make the limiting screw abut against the limiting rack to fix the second gear. The second gear does not rotate and locks the first gear, causing the pulley to stop rotating, thus facilitating the transfer of the cabinet. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 5 and Figure 6 This utility model provides an embodiment of a laboratory cabinet with odor prevention, comprising a cabinet 1, three placement boards 2 fixedly connected to the inner wall of the cabinet 1, and four support frames 4 fixedly connected to the bottom of the cabinet 1. A pulley 14 is rotatably connected to the inner wall of each support frame 4. A first gear 15 is fixedly connected to both the front and rear ends of each pulley 14. A second gear 16 is meshed with the top side of the outer wall of each first gear 15. By locking the first gear 15 with the second gear 16, the pulley 14 is immobilized. Furthermore, the rotation of the pulley 14 drives the first gear 15 to rotate, causing the second gear 16 to rotate in a regular pattern. The inner wall of the support frame 4 has a limited sliding connection. The limiting rack 17 has its right side meshing with the left side of the second gear 16, fixing the second gear 16 in place. The second gear 16 does not rotate, locking the first gear 15 and stopping the pulley 14 from rotating. Four third springs 18 are fixedly connected to the left side of the inner wall of the support frame 4. The right end of each third spring 18 is fixedly connected to the left side of the limiting rack 17. After the limiting rack 17 is released, the third springs 18 pull the limiting rack 17 to slide. A limiting screw 5 is threadedly connected to the left side of the support frame 4. The right end of the limiting screw 5 abuts against the left side of the limiting rack 17, causing the limiting screw 5 to abut against the limiting rack 17 and slide.

[0025] Reference Figure 1 , Figure 3 and Figure 4The cabinet 1 has three placement blocks 3 fixedly connected to its inner wall. Three limiting slots are provided on the right side of the cabinet 1. Storage shells 10 are inserted into the right side of the placement blocks 3, and activated carbon, bamboo charcoal, or other adsorbents are placed inside the storage shells 10 to absorb odor molecules. Limiting blocks 11 are slidably connected to the inner wall of the limiting slots. The rear side of the limiting blocks 11 is inserted into the front side of the storage shells 10. Four second springs 12 are installed inside the limiting slots. One end of each second spring 12 is fixedly connected to the front side of the inner wall of the limiting slot, and the other end is fixedly connected to the front side of the limiting blocks 11. The second springs 12 release their elastic force to push the limiting blocks 11 to slide, allowing them to insert into the storage shells 10 and secure them. A grabbing block 13 is fixedly connected to the right side of the limiting blocks 11. Grabbing the grabbing block 13 causes the limiting blocks 11 to slide, releasing the fixation on the storage shells 10. (See reference...) Figure 2 At least twenty limiting boxes 6 are fixedly connected to the top of the placement plate 2. Two first springs 9 are fixedly connected to the left and right sides of the inner wall of the limiting box 6. Limiting clamps 8 are fixedly connected to the near ends of the first springs 9 on the left and right sides. The first springs 9 push the limiting clamps 8 to slide and clamp the medicine bottle. Anti-slip pads 7 are fixedly connected to the top of the placement plate 2 to prevent the medicine bottle from slipping.

[0026] Working principle: When the cabinet 1 is in normal use, activated carbon, bamboo charcoal and other adsorbents are placed in the storage shell 10 to absorb odor molecules. When the adsorbent is used for a long time, it needs to be replaced. Grab the gripping block 13 to drive the limiting plug 11 to slide, release the fixation of the storage shell 10, pull out the storage shell 10, replace the adsorbent in the storage shell 10. After the replacement is completed, insert the storage shell 10 back into the placement block 3, release the gripping block 13, the second spring 12 releases the elastic force to push the limiting plug 11 to slide, and the limiting plug 11 inserts into the storage shell 10 to fix the storage shell 10.

[0027] When cabinet 1 needs to be moved, tighten the limit screw 5 to release the fixation of the limit rack 17. The third spring 18 pulls the limit rack 17 to slide, releasing the connection between the limit rack 17 and the second gear 16, allowing the second gear 16 to rotate. At the same time, the pulley 14 can also rotate to move cabinet 1. After cabinet 1 is moved, tighten the limit screw 5 so that the limit screw 5 abuts against the limit rack 17 to fix the second gear 16. The second gear 16 does not rotate and locks the first gear 15, causing the pulley 14 to stop rotating.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
