Description

Technical Field

[0001] This utility model relates to the field of chemical storage technology, and in particular to a testing and fixing rack for hazardous chemicals. Background Technology

[0002] Throughout the entire lifecycle of hazardous chemicals, especially during critical stages such as the bumps during transportation, the static pressure during storage and stacking, and the frequent operations during laboratory testing, the containers are always exposed to physical risks caused by accidental drops, violent collisions, or continuous vibrations. Once a container breaks or its seal fails, the highly toxic, corrosive, flammable, and explosive chemicals inside will leak, causing not only the loss of valuable samples and environmental pollution, but also potentially triggering catastrophic safety accidents such as fires, explosions, or poisoning, with unimaginable consequences. In order to fundamentally curb such risks and provide an absolutely stable and reliable constraint for precise and dangerous testing operations, testing fixtures specifically designed to fix and protect these chemical containers have emerged as a key safety device and have become an indispensable part of modern chemical safety management systems.

[0003] Currently, when sampling or testing hazardous chemicals (such as flammable, volatile, and toxic liquids) in the laboratory, containers are often placed directly on the table, which poses a risk of slipping or being overturned. Operators also need to manually hold them steady at close range, exposing them to danger. Existing fixtures are mostly simple clamps with poor adaptability, cumbersome operation, and lack active protection designs for risks such as leakage and volatilization.

[0004] Therefore, it is necessary to design a fixing frame to prevent chemical containers from being overturned and to prevent their leakage and volatilization, so as to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing fixtures, such as the risk of slipping or being overturned when sampling hazardous chemicals, as well as the risk of leakage and volatilization, the technical problem is to provide a fixture for the testing of hazardous chemicals.

[0006] The technical solution is as follows: A testing and fixing frame for hazardous chemicals includes a base plate, supports, anti-tilt bases, screws, knobs, sliding frames, sealing covers, bottom rings, sealing blocks, sealing caps, and sealing rings. Several supports are fixed to the top of the base plate and arranged horizontally in sequence. An anti-tilt base is fixed to the lower part of each support. A screw is rotatably connected to the upper left side of each support, and a knob is connected to the top of each screw. Sliding frames are slidably connected between the upper parts of the supports, and each sliding frame is threaded to the outer wall of the screw on the left side of the corresponding support. A sealing cover is inserted through the middle of each sliding frame. A bottom ring is connected to the bottom of each sealing cover, and a sealing block is connected to the inner side of each bottom ring. A sealing cap is threaded to the outer wall of the upper opening of the sealing cover, and a sealing ring is provided on the inner wall of the upper opening of the sealing cover.

[0007] Furthermore, it also includes limit plates, connecting rods, retaining rings, connecting columns, sliders, retaining pins, rotating rings, and springs. Limit plates are fixed to both sides of the bracket. Connecting rods are rotatably connected to both sides of the upper part of the anti-tilt base. Retaining rings are fixed to the upper sides of the two corresponding connecting rods that are close to each other. Connecting columns are fixed to the right side of the front part of the left retaining ring. Retaining holes are symmetrically opened in the front part of the right retaining ring. Sliders are slidably connected to the outer wall of the connecting column. Retaining pins are symmetrically fixed to the left side of the rear part of the slider, and the two retaining pins are inserted into the two corresponding retaining holes. Rotating rings are rotatably connected to the right side of the slider. Springs are connected between the rotating rings and the right side of the corresponding connecting column.

[0008] Furthermore, it also includes a collection frame and absorbent paper. A collection frame is fixed to the top of each sealing cover. The collection frame has an inclined design with a lower center and higher edges. Absorbent paper is provided between the inner side wall of the collection frame and the top of the corresponding sealing cover. Both the collection frame and the absorbent paper are located next to the opening of the corresponding sealing cover.

[0009] Furthermore, it also includes a mounting base and a suction cup. Mounting bases are fixed to both sides of the base plate, and suction cups are fixed to the sides of the two mounting bases that are far apart from each other, with the suction cups facing the ground.

[0010] Furthermore, it also includes a glass plate; the outer wall of the sealing cover is equipped with a glass plate, which allows users to observe the inside of the sealing cover in real time.

[0011] Furthermore, the sealing block, sealing ring, and absorbent paper are all designed to be detachable.

[0012] The beneficial effects are as follows: 1. This utility model achieves convenient and stable clamping of containers of various specifications through the cooperation of anti-tilting base, connecting rod, retaining ring, connecting column, retaining hole, slider, retaining column, rotating ring and spring. Operators can complete the fixing and release of containers by simple pushing, pulling and rotating actions, overcoming the shortcomings of poor adaptability and cumbersome operation of existing clamps, and achieving a fast, universal and firm anti-tilting fixing effect.

[0013] 2. This utility model, through a sealed space consisting of a sealing cover, bottom ring, sealing block, sealing cap and sealing ring, combined with a secondary collection design of collection frame and absorbent paper, can reliably seal the container opening and effectively prevent the volatilization and leakage of internal chemicals, while also collecting and treating splashes or condensates that may be generated during operation. It overcomes the shortcomings of existing technologies that lack active protection design, and achieves the effect of multiple protections, ensuring operational safety and environmental cleanliness.

Detailed Implementation

[0024] Example:

[0025] A testing fixture for hazardous chemicals, such as Figures 1-7 and Figure 9 As shown, the system includes a base plate 1, brackets 2, anti-tilt bases 3, screws 4, knobs 5, sliding frames 6, sealing covers 7, bottom rings 9, sealing blocks 10, sealing caps 11, and sealing rings 12. Several brackets 2 are fixedly attached to the top of the base plate 1, arranged horizontally. Each bracket 2 has an anti-tilt base 3 fixedly attached to its lower part. Screws 4 are rotatably connected to the upper left side of each bracket 2, with knobs 5 connected to the top of each screw 4. Sliding frames 6 are slidably connected between the upper parts of each bracket 2, and each sliding frame 6 is threaded to the outer wall of the screw 4 on the left side of the corresponding bracket 2. A sealing cover 7 is fixedly inserted through the middle of each sliding frame 6. A bottom ring 9 is connected to the bottom of each sealing cover 7, and sealing blocks 10 are connected to the inner side of each bottom ring 9. A sealing cap 11 is threaded to the outer wall of the upper opening of each sealing cover 7. The upper part of the cover 7 has a sealing ring 12 on the inner wall of the cover opening, and also includes a collection frame 13 and an adsorption paper 14. The top of the cover 7 is fixed with a collection frame 13. The collection frame 13 is a sloping design with a low center and high sides. The inner wall of the collection frame 13 and the top of the corresponding cover 7 are provided with adsorption paper 14. The collection frame 13 and the adsorption paper 14 are located next to the cover opening of the corresponding cover 7. It also includes a fixing seat 24 and a suction cup 25. The bottom plate 1 has a fixing seat 24 fixed on both sides. The two fixing seats 24 are fixed on the side that is far away from each other. The suction cup 25 faces the ground. It also includes a glass plate 8. The outer wall of the cover 7 is provided with a glass plate 8 to facilitate the user to observe the inside of the cover 7 in real time. The sealing block 10, the sealing ring 12 and the adsorption paper 14 are all detachable.

[0026] like Figures 6-8 As shown, it also includes a limit plate 15, a connecting rod 16, a retaining ring 17, a connecting column 18, a slider 20, a retaining column 21, a rotating ring 22, and a spring 23. The left and right sides of the bracket 2 are fixed with limit plates 15. The upper sides of the anti-tilt base 3 are rotatably connected with connecting rods 16. The upper sides of the two corresponding connecting rods 16 are fixed with retaining rings 17. The right side of the front part of the left retaining ring 17 is fixed with a connecting column 18. The front part of the right retaining ring 17 is symmetrically provided with retaining holes 19. The outer wall of the connecting column 18 is slidably connected with sliders 20. The left side of the rear part of the slider 20 is symmetrically fixed with retaining columns 21, and the two retaining columns 21 are respectively inserted into the two corresponding retaining holes 19. The right side of the slider 20 is rotatably connected with a rotating ring 22. The rotating ring 22 is connected to the right side of the corresponding connecting column 18 with a spring 23.

[0027] When using this device to test or sample hazardous chemicals, the operator first places the device stably on the workbench. Since both sides of the base plate 1 are fixed with mounting bases 24, and the sides of the mounting bases 24 furthest from each other are fixed with suction cups 25 facing the ground, pressing the device utilizes the negative pressure suction provided by the suction cups 25 to firmly fix the entire mounting frame to the workbench, effectively preventing it from sliding or shifting during operation, providing a stable foundation for subsequent operations. After fixing the device, the operator begins to place the chemical container to be tested. First, the slider 20 is pushed to the right. The slider 20 moves the rotating ring 22 and compresses the spring 23. Then, the locking pin 21 fixed to the slider 20 opens through the locking hole 19 of the right locking ring 17. To release the lock, rotate slider 20 90 degrees to disengage the locking pin 21 and locking hole 19 from parallel. The operator can then flip the two locking rings 17 outwards. The locking rings 17 are blocked when they contact the limiting plate 15, preventing excessive rotation. At this point, under the elastic force of spring 23, slider 20 tends to return to its original position to the left. Next, place the chemical container on the anti-tilt base 3. The anti-tilt base 3 is designed to ensure the container is upright and prevent it from tilting naturally. Then, close the locking rings 17 on both sides inwards, so that the container is securely held between the two locking rings 17. After closing, push slider 20 to the right. Slider 20 drives the rotating ring 22 to move and compress spring 23 again, then moves in the opposite direction to the previous movement. Rotate slider 20 ninety degrees again. At this point, locking pin 21 is parallel to locking hole 19. Insert locking pin 21 precisely into locking hole 19 to securely lock ring 17, achieving initial fixation of the lower part of the container and effectively preventing it from tipping over or slipping. After fixing the lower part of the container, the operator rotates knob 5 clockwise. Knob 5 drives screw 4 connected to it to rotate. The sliding frame 6 and support 2 are slidably connected. The rotation of screw 4 will drive the sliding frame 6 to move smoothly downward along support 2. The sliding frame 6 drives the entire sealing cover 7 assembly on it to move downward until the bottom ring 9 and sealing block 10 at the bottom of the sealing cover 7 are tightly pressed against the platform at the container opening, forming the first sealing barrier. If a sealing operation or prevention of volatilization is required, the operator... The sealing cover 7 can be adjusted downwards until the container opening is completely submerged inside. Then, the sealing cap 11 is tightened clockwise. The sealing cap 11 is threaded to the upper opening of the sealing cover 7 and presses against the sealing ring 12 inside the opening, thus forming a completely sealed space above the container opening. This effectively prevents the volatilization and leakage of internal chemicals. Throughout the testing process, the operator can observe the changes in the liquid level inside the container and the condition inside the sealing cover 7 in real time through the glass plate 8 on the outer wall of the sealing cover 7 without opening the sealing cap 11, ensuring safety without obstructing observation. If a small amount of liquid accumulates at the top of the sealing cover 7 due to splashing or condensation during operation, the inclined design of the collection frame 13, which is lower in the middle and higher around the edges, can effectively guide the liquid flow towards the center.The absorbent paper 14 installed between the inner wall of the collection frame 13 and the top of the sealing cover 7 can absorb the liquid in time, preventing it from dripping and causing pollution or danger, thus forming another safety protection measure. After all operations are completed, when it is necessary to remove the container, loosen and remove the sealing cap 11 counterclockwise, rotate the knob 5 counterclockwise to make the sliding frame 6 lift the sealing cover 7, and then open the retaining ring 17 to safely remove the container. At this point, the fixation and protection measures for hazardous chemicals are completed.
