Description

Technical Field

[0001] This utility model relates to the field of hazardous materials protection technology, specifically a safety protection device for hazardous chemical production. Background Technology

[0002] Publication No.: "CN216233645U" discloses a safety protection device for hazardous chemical production. This utility model includes a protective box and a protective structure. The upper surface of the protective box has a circular hole. The upper surface of the protective box is equipped with a protective structure, which includes two racks slidably inserted into the surface of the protective box. A base plate is fixedly mounted at the lower end of the two racks. A dispensing box is located on the side of the base plate near the racks. A support frame is fixedly mounted on the upper surface of the protective box. A rotating shaft is rotatably connected to the surface of the support frame. Two gears are fixedly mounted on the arc surface of the rotating shaft, and the teeth of the gears mesh with the racks. This invention solves the problem of inadequate protection of hazardous chemicals during the dispensing of raw materials, and the frequent occurrence of misalignment between pipelines and the dispensing box opening, leading to leaks and significantly increasing safety hazards during the dispensing of hazardous chemicals.

[0003] The main purpose of the above technology is to ensure that the opening of the packaging box aligns precisely with the external pipeline. However, when packaging hazardous chemicals, only packaging boxes of the same length and width can be used. Furthermore, there are no limiting structures on the sides of the packaging box when it is placed, which makes it easy for the packaging box to shift when it is pushed into the protective box, resulting in the opening of the packaging box not aligning with the external pipeline. At the same time, it is not very convenient to remove the packaging box. Utility Model Content

[0004] To address the problem that different lengths and widths of packaging boxes cannot be used, and that the lack of a limiting structure makes them inconvenient to remove during placement, the purpose of this utility model is to provide a safety protection device for hazardous chemical production.

[0006] Preferably, a ruler plate is fixedly installed at the top of each of the two movable plates, and the ruler plate is located on the lower surface of the inner wall of the U-shaped block.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application enables the use of packaging boxes of different lengths and widths, improving adaptability and preventing misalignment when placing the packaging boxes;

[0009] 2. This application provides a clearer understanding of where the U-shaped block needs to be moved to ensure that the opening of the packaging box that is in contact with the convex plate aligns with the round hole. Attached Figure Description

[0018] 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.

[0019] Example: Figure 1-6 As shown, this utility model provides a safety protection device for hazardous chemical production, including a base 1. Two sets of symmetrically distributed support rods 11 are fixedly installed at the top of the base 1. A top plate 12 is fixedly installed at the top of the support rods 11. A circular hole 13 is opened through the top of the top plate 12. A fixing component 14 is provided on the upper surface of the top plate 12. A placement plate 2 is provided on the upper surface of the base 1. Two fixing blocks 21 are fixedly installed at each of the two corners of the top of the placement plate 2. A second double-headed screw 22 is rotatably installed on the top of the fixing blocks 21. Two symmetrically distributed movable plates 23 are connected to the outer side threadedly. The top of each movable plate 23 is provided with a U-shaped block 24. Two U-shaped frames 25 are fixedly installed at the two corners of the top of the U-shaped block 24. A convex plate 26 is provided on the U-shaped frame 25. A limit rod 27 is fixedly installed between the two fixed blocks 21. The movable plate 23 slides on the outside of the limit rod 27. A first screw 28 is threadedly connected to the upper surface of each U-shaped block 24. A disc 29 is fixedly installed at the bottom end of the first screw 28. A movable component 5 is provided above the base 1.

[0020] When installing the U-shaped frame 25 on the U-shaped block 24, it should be noted that the front side of the U-shaped frame 25 is not flush with the front side of the U-shaped block 24, and after placing the convex plate 26 on the U-shaped frame 25, the front side of the convex plate 26 needs to be flush with the front side of the U-shaped block 24. The base 1 is supported by two sets of symmetrically distributed support legs.

[0021] A ruler plate 4 is fixedly installed on the top of each of the two movable plates 23. The ruler plate 4 is located on the lower surface of the inner wall of the U-shaped block 24. When the ruler plate 4 is installed on the movable plate 23, the top surface of the ruler plate 4 does not fit against the lower surface of the inner wall of the U-shaped block 24.

[0022] The fixing assembly 14 includes two symmetrically distributed fixing plates 15, which are fixed to the top plate 12. A first double-ended screw 16 is rotatably mounted on one side of the two fixing plates 15. Two symmetrically distributed clamping rings 17 are threaded to the outer side of the first double-ended screw 16. The two clamping rings 17 are opposite to each other. A guide rod 18 is fixedly mounted on the other side of the two fixing plates 15. The clamping rings 17 are slidably sleeved on the outside of the guide rod 18. By setting the first double-ended screw 16, when the wheel on the first double-ended screw 16 is rotated, the first double-ended screw 16 is driven to rotate. Then, the clamping rings 17 are driven to move towards the middle by the limit of the guide rod 18, thereby clamping the box opening and the matching external pipe, realizing the fixing of external pipes of different diameters.

[0023] The movable component 5 includes two second screws 51 with the same thread direction. The second screws 51 are threadedly connected to the placement plate 2 and rotatably connected to the top plate 12 and the base 1. A worm gear 52 is fixedly installed at the bottom end of the second screw 51. A worm 53 is meshed with the outer side of the worm gear 52. A connecting rod 54 is fixedly installed between the two worms 53. A fixed seat 55 is rotatably sleeved on the outside of the connecting rod 54. The fixed seat 55 is fixedly connected to the base 1. By setting the worm 53, when the worm 53 and the connecting rod 54 rotate, they drive the worm gear 52 and the second screws 51 to rotate. As the second screws 51 rotate, the components on the placement plate 2 and the sub-packing box move upward, so that the external pipe is accurately fitted onto the opening of the sub-packing box.

[0024] One end of one of the worm gears 53 is fixedly mounted with a first bevel gear 56, and an L-shaped block 50 is fixedly mounted at the top edge of the base 1. A rotating shaft 57 is rotatably passed through the top of the L-shaped block 50, and a second bevel gear 58 that works with the first bevel gear 56 is fixedly mounted at the bottom of the rotating shaft 57. By setting the rotating shaft 57, when the rotating wheel on the rotating shaft 57 is rotated, the rotating shaft 57 and the second bevel gear 58 are driven to rotate. The meshing of the second bevel gear 58 and the first bevel gear 56 drives the worm gear 53 to rotate, thus making it easier for the worm gear 53 and the connecting rod 54 to rotate.

[0025] Each U-shaped block 24 has a locking block 6 fixedly installed on both sides of its inner wall, and each movable plate 23 has a slot 61 on both sides that cooperates with the locking block 6. By setting the locking block 6 and the slot 61, the U-shaped block 24 is more stable when it moves, and at the same time, it plays a guiding role for the U-shaped block 24.

[0026] Each movable plate 23 is fixedly installed with a slider 7 at its bottom edge. The slider 7 is on the opposite side of the fixed block 21. The upper surface of the plate 2 is provided with a groove 71 that works with the slider 7. By setting the slider 7 and the groove 71, when the movable plate 23 moves, the slider 7 slides in the groove 71, thereby making the movable plate 23 more stable when it moves.

[0027] Rubber pads are fixedly installed at the bottom of the disc 29 and on the inner side of the clamping ring 17. By setting the rubber pads, the disc 29 is more stable when fixing the U-shaped block 24 on the moving plate 23. At the same time, the rubber pads on the clamping ring 17 also make it more stable when clamping external pipes.

[0028] Working principle: In actual use, when repackaging hazardous chemicals, first, adjust the distance between the two moving plates 23 and the position of the convex plate 26 according to the length and width of the repackaging box. When adjusting the position of the moving plates 23, first place the box on the placement plate 2, and then rotate the second double-headed screw 22. Due to the limiting rod 27 limiting the moving plates 23, the rotation of the second double-headed screw 22 drives the two moving plates 23 to move towards the middle, so that the moving plates 23 fit against the two sides of the repackaging box. After adjustment, remove the repackaging box from the placement plate 2, and then adjust the convex plate 26 according to the width of the repackaging box.

[0029] When adjusting the position of the convex plate 26, first remove the convex plate 26 from the U-shaped frame 25. Then, move the corresponding U-shaped block 24. When moving the U-shaped block 24, observe the scale line on the ruler plate 4. After moving it to the desired position, rotate the wheel on the first screw 28 to move the disc 29 downward, so that the rubber pad on the disc 29 is in contact with the top surface of the ruler plate 4, thereby fixing the U-shaped block 24 on the moving plate 23. Then, place the convex plate 26 on the U-shaped frame 25. Once everything is adjusted, place the packaging box on the placement plate 2, and make the two sides of the packaging box fit with the inner side of the moving plate 23. The adjacent sides of the packaging box and the moving plate 23 should fit with the convex plate 26. Then, insert the external pipe into the round hole 13 and fix the external pipe with the fixing component 14. Then, move the packaging box upward with the moving component 5 so that the external pipe fits onto the opening of the packaging box. Then, the packaging can be performed.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
