Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, and in particular to a protective device. Background Technology

[0002] Chemical engineering encompasses chemical processes, chemical industry, and chemical engineering. It refers to the technology of using chemical methods to change the composition and structure of substances or synthesize new substances. All of these belong to chemical production technology, also known as chemical processes. The resulting products are called chemicals or chemical products. In the process of chemical production, in order to avoid accidents, protective devices are usually installed on chemical production equipment. Users place reagent bottles inside the equipment to prevent solvents from splashing out of the reagent bottles after a chemical reaction or reagents from splashing out of the reagent bottles if the bottles break.

[0003] For example, Chinese utility model patent (CN214973884U) discloses a chemical safety protective device, which states: "This chemical safety protective device can effectively prevent toxic gases generated after chemical reagents react inside the reagent tube from leaking out from the inside of the outer casing, or prevent the mixed chemical reagents from splashing out from the inside of the outer casing, effectively improving the practicality of the device. Through the combination of a fixed base, spring, pressing block, pressing rod, connecting groove, and snap-fit ​​block, it is convenient for users to carry or hold the outer casing to view the chemical reagents placed inside, thereby effectively improving the portability and practicality of the device." It also states: "However, it is inconvenient for users to continue adding chemical solvents to the reagent bottle when it is placed inside the protective device. Furthermore, although existing chemical safety protective devices can be shaken to accelerate the mixing of the solution inside the reagent bottle, it is not convenient to disassemble the device for users to move or hold it by hand."

[0004] In summary, existing technologies utilize a movable cylinder with a rubber stopper and connecting rod to inject the solution from the movable cylinder into the reagent tube, relying on the bottom of the movable cylinder to act as a cap for the reagent tube, preventing the solution from leaking out when the reagent tube is shaken. However, this method has the following technical problems: the dimensions of reagent bottles used in actual chemical production vary, and the bottom of the movable cylinder may not match the size of the bottle opening, causing the solution to spill out when the reagent bottle is shaken. The applicability of this device is relatively limited. Therefore, this application proposes a protective device to solve the technical problems mentioned in the above-mentioned patents and provide a new technical solution. Utility Model Content

[0005] Therefore, it is necessary to provide a protective device to address the aforementioned technical problems. By rotating the protective cap, it can be separated from the device housing. A cap compatible with the opening of the reagent bottle can then be placed between two grippers. Subsequently, rotating the bidirectional threaded rod controls the two moving blocks to move closer together under the constraint of the fixed plate. The two grippers then clamp the reagent bottle cap. In subsequent use, when it is necessary to block the reagent bottle opening, first rotate the limiting screw out of the protective cap, then rotate the rotating plate so that the fixed plate is directly above the reagent bottle. Then, rotate the limiting screw back into the protective cap. The position of the rotating plate is then adjusted. The device restricts movement, causing the threaded column to rotate and bring the cap closer to the reagent bottle, ultimately sealing it. By using a cap that matches the actual reagent bottle, the device prevents spillage when the bottle is shaken. The distance between the two grippers can be adjusted via a bidirectional threaded rod, allowing for the clamping of caps of various sizes. This design protects reagent bottles with different opening sizes, increasing the device's applicability. Furthermore, multiple threaded cylinders on the rotating disc allow for the addition of different reagents, facilitating the injection of various reagents into the bottle and enhancing the device's practicality.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The inner walls of the plurality of threaded cylinders are slidably connected with pistons, and the tops of the plurality of pistons are fixedly connected with push-pull rods.

[0012] In a preferred embodiment of the protective device provided by this utility model, the limiting component includes limiting blocks, and multiple limiting blocks are fixedly connected to the top of the rotating disk. The inner walls of the multiple limiting blocks are threaded with limiting screws, and the multiple limiting screws are movably inserted into the protective cover.

[0013] In a preferred embodiment of the protective device provided by this utility model, the installation assembly includes a threaded column, the inner wall of the rotating disk is threadedly connected to the threaded column, the bottom end of the threaded column is fixedly connected to a fixed disk, the inner wall of the fixed disk is rotatably connected to a bidirectional threaded rod, the outer wall of the bidirectional threaded rod and the two sides located in the middle are respectively threadedly connected to movable blocks, both of the movable blocks are slidably connected to the inner wall of the fixed disk, and the bottom of both movable blocks are fixedly connected to grippers.

[0014] As a preferred embodiment of the protective device provided by this utility model, the clamping mechanism includes a socket, a placement cylinder, a clamping assembly, and a plugging assembly. The lower inner wall of the device housing is provided with a plurality of sockets, and the placement cylinder is fixedly connected to the lower inner wall of the device housing.

[0015] In a preferred embodiment of the protective device provided by this utility model, the clamping assembly includes a rotating column, the inner wall of the placement cylinder is rotatably connected to the rotating column, the outer wall of the rotating column is fixedly connected to a gear, the outer wall of the gear and the front and rear sides are respectively meshed with racks, the two racks are slidably connected to the inner wall of the placement cylinder, the top of the two racks are fixedly connected to an arc plate, the side of the two arc plates that are far apart from each other is fixedly connected to a sliding rod, the two sliding rods are slidably connected to the inner wall of the placement cylinder, and the outer wall of the rotating column is fixedly connected to a pull plate.

[0016] In a preferred embodiment of the protective device provided by this utility model, the plug-in assembly includes a housing, the top of the pull plate is fixedly connected to the housing, the inner wall of the housing is slidably connected to a plug rod, the bottom end of the plug rod passes through the pull plate and is movably inserted into the plug hole, the outer wall of the plug rod is fixedly connected to a fixing ring, the fixing ring is slidably connected to the inner wall of the housing, and a spring is sleeved on the outside of the plug rod, the two ends of the spring being fixedly connected to the inner wall of the housing and the outer wall of the fixing ring, respectively.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The protective device provided by this utility model allows the protective cover to be separated from the outer casing by rotating it. A cap adapted to the mouth of the reagent bottle can then be placed between two grippers. Rotating the bidirectional threaded rod controls the two moving blocks to move closer together under the constraint of the fixed plate. The two grippers then clamp the reagent bottle cap. In subsequent use, when it is necessary to block the reagent bottle mouth, first rotate the limiting screw out of the protective cover, then rotate the rotating plate so that the fixed plate is directly above the reagent bottle. Then, rotate the limiting screw into the protective cover to restrict the position of the rotating plate. Rotating the threaded rod brings the cap closer to the reagent bottle and finally seals it. By using a cap that matches the actual reagent bottle, the bottle opening is sealed, reducing the possibility of solution spillage when the bottle is shaken. The distance between the two grippers can be adjusted via the bidirectional threaded rod, allowing for the clamping of caps of various sizes. This means the device can protect reagent bottles with various opening sizes, increasing its applicability. Furthermore, the multiple threaded cylinders on the rotating disc allow for the addition of different reagents, facilitating the operator to inject various reagents into the bottle and enhancing the device's practicality.

[0019] The protective device provided by this utility model, through the placement cylinder receiving the reagent bottle, can initially restrict the position of the reagent bottle. By pulling up the insertion rod, the insertion rod is disengaged from the insertion hole, and then the insertion rod can pull the pull plate, which in turn rotates the rotating column. This, in turn, causes the two racks to move, allowing the two arc-shaped plates to move closer together, thus further clamping and restricting the reagent bottle. Once the reagent bottle is stably clamped, the insertion rod can be released, allowing it to insert into the corresponding insertion hole. The gear simultaneously drives the two racks to move, ultimately clamping the reagent bottle at the center of the placement cylinder. This bidirectional rotation... The threaded rod causes the two moving blocks to move simultaneously, clamping the cap at the center of the fixed plate. This reduces the possibility of failure to seal the reagent bottle opening due to misalignment of the cap and the reagent bottle during the process of rotating the threaded rod to place the cap on the reagent bottle, thus improving the stability of the device. Furthermore, the clamping process for the reagent bottle is relatively simple, improving the operator's efficiency in clamping the reagent bottle. By clamping the reagent bottle, the movement of the reagent bottle relative to the placement cylinder is reduced when the device shakes, thereby reducing the possibility of the reagent bottle hitting the outer wall of the placement cylinder and breaking, and improving the practicality of the device.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] As described in the background art, however, the sizes of reagent bottles used in actual chemical production vary, and the bottom of the movable cylinder may not match the size of the bottle opening, causing the solution inside to spill out when the reagent bottle is shaken, thus limiting the applicability of the device.

[0033] To solve this technical problem, this utility model provides a protective device that is applied to chemical safety.

[0034] For details, please refer to Figures 1-3 The protective devices specifically include:

[0035] The device housing 1 has an observation window 2 fixedly connected to its inner wall. The top of the device housing 1 is detachably connected to a protective cover 3 via threads. The protective cover 3 is equipped with a processing mechanism 4. The lower surface of the inner wall of the device housing 1 is equipped with a clamping mechanism 5.

[0036] The processing mechanism 4 includes a rotating disk 6, a T-shaped rail 7, an injection assembly, a limiting assembly, and an installation assembly. The inner wall of the protective cover 3 is rotatably connected to the T-shaped rail 7, and the outer wall of the T-shaped rail 7 is fixedly connected to the rotating disk 6.

[0037] The protective device provided by this utility model allows the protective cover 3 to be separated from the outer casing 1 by rotating it. A cap adapted to the mouth of the reagent bottle can then be placed between the two grippers 17. Next, rotating the bidirectional threaded rod 15 controls the two moving blocks 16 to move closer together under the constraint of the fixed plate 14. The two grippers 17 then clamp the reagent bottle cap. In subsequent use, when it is necessary to block the reagent bottle mouth, first rotate the limiting screw 12 until it is out of the protective cover 3, then rotate the rotating plate 6 so that the fixed plate 14 is positioned directly above the reagent bottle. Then, rotate the limiting screw 12 back into the protective cover 3. The position of the rotating plate 6 is then adjusted accordingly. The device restricts the flow of liquid by rotating the threaded rod 13, bringing the cap closer to the reagent bottle and finally sealing it. The cap, adapted to the specific reagent bottle being used, blocks the bottle opening, reducing the risk of solution spillage when the bottle is shaken. The distance between the two grippers 17 can be adjusted via the bidirectional threaded rod 15, allowing for the clamping of caps of various sizes. This design protects reagent bottles with different opening sizes, expanding the device's applicability. Furthermore, the multiple threaded cylinders 8 on the rotating disk 6 allow for the addition of different reagents, facilitating the injection of various reagents into the bottle and enhancing the device's practicality.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0039] Example 1:

[0040] Please refer to Figures 2-5 A protective device comprising:

[0041] The liquid injection assembly includes a threaded cylinder 8. Multiple threaded cylinders 8 are threadedly connected to the inner wall of the rotating disk 6. A piston 10 is slidably connected to the inner wall of each of the multiple threaded cylinders 8. A push-pull rod 9 is fixedly connected to the top of each of the multiple pistons 10. Liquid can be injected into the reagent bottle through the liquid injection assembly. The length of the threaded cylinder 8 below the protective cover 3 can be adjusted through the threaded connection between the threaded cylinder 8 and the rotating disk 6, which facilitates the operator's liquid injection operation. When the limiting screw 12 is inserted into the protective cover 3 and the threaded cylinder 8 is above the placement cylinder 19, the central axis of the insertion hole 18 is collinear with the central axis of the placement cylinder 19. A scale can be set on the outside of the push-pull rod 9.

[0042] The limiting component includes limiting blocks 11. Multiple limiting blocks 11 are fixedly connected to the top of the rotating disk 6. The inner walls of the multiple limiting blocks 11 are threaded with limiting screws 12. The multiple limiting screws 12 are movably inserted into the protective cover 3. The limiting blocks 11 are set on the rotating disk 6 at positions corresponding to the threaded cylinder 8 or the threaded column 13. The limiting component prevents the rotating disk 6 and the T-rail 7 from moving relative to the protective cover 3.

[0043] The mounting assembly includes a threaded post 13. The inner wall of the rotating disk 6 is threaded with the threaded post 13. The bottom end of the threaded post 13 is fixedly connected to a fixed disk 14. The inner wall of the fixed disk 14 is rotatably connected to a bidirectional threaded rod 15. The outer wall of the bidirectional threaded rod 15 and the two sides located in the middle are respectively threaded with moving blocks 16. Both moving blocks 16 are slidably connected to the inner wall of the fixed disk 14. The bottom of both moving blocks 16 is fixedly connected to a clamp 17. When the limiting screw 12 is inserted into the protective cover 3 and the fixed disk 14 is located above the placement cylinder 19, the central axis of the fixed disk 14 is collinear with the central axis of the placement cylinder 19. The cover of the reagent bottle to be used can be installed on the fixed disk 14 through the mounting mechanism.

[0044] With the above structural design, during device assembly and use, firstly, rotating the protective cover 3 separates it from the outer casing 1. Then, a cap matching the mouth of the reagent bottle can be placed between the two grippers 17. Next, rotating the bidirectional threaded rod 15 controls the two moving blocks 16 to move closer together under the constraint of the fixed plate 14. The two grippers 17 then clamp the reagent bottle cap, and the solution to be added to the reagent bottle is injected into the clean threaded cylinder 8. During this process, the bottom of the threaded cylinder 8 is placed in the solution, and then the push rod 9 is pulled to cause the piston 10 to slide inside the threaded cylinder 8, drawing the solution into it. Finally, the protective cover 3 is threaded onto the outer casing 1 for subsequent use. When it is necessary to block the reagent bottle opening, first rotate the limiting screw 12 away from the protective cap 3, then rotate the rotating disk 6 so that the fixed disk 14 is directly above the reagent bottle. Then rotate the limiting screw 12 into the protective cap 3 to restrict the position of the rotating disk 6. Then rotate the threaded column 13 to bring the cap closer to the reagent bottle and finally close it on the reagent bottle. When it is necessary to inject solution into the reagent bottle, control the limiting screw 12 to leave the protective cap 3, move the threaded cylinder 8 containing the solution to be injected to the top of the reagent bottle, then rotate the limiting screw 12 into the protective cap 3, then push the push-pull rod 9 down, which will drive the corresponding piston 10 to slide inside the threaded cylinder 8, and then squeeze the solution in the threaded cylinder 8 into the reagent bottle.

[0045] Example 2:

[0046] The protective device provided in Example 1 has been further optimized, specifically, as follows: Figures 6-8 As shown, the clamping mechanism 5 includes a socket 18, a placement cylinder 19, a clamping assembly, and a plug-in assembly. Multiple sockets 18 are provided on the lower inner wall of the device housing 1. The placement cylinder 19 is fixedly connected to the lower inner wall of the device housing 1. The sockets 18 cooperate with the plug rod 27 to restrict the position of the arc plate 23.

[0047] The clamping assembly includes a rotating column 21, which is rotatably connected to the inner wall of the placement cylinder 19. A gear 20 is fixedly connected to the outer wall of the rotating column 21. A rack 22 meshes with the outer wall of the gear 20 on both the front and rear sides. Both racks 22 are slidably connected to the inner wall of the placement cylinder 19. An arc-shaped plate 23 is fixedly connected to the top of each of the two racks 22. A sliding rod 24 is fixedly connected to the side of each arc-shaped plate 23 that is far apart from each other. Both sliding rods 24 are slidably connected to the inner wall of the placement cylinder 19. A pull plate 25 is fixedly connected to the outer wall of the rotating column 21. The reagent bottle can be clamped and positioned by the clamping assembly.

[0048] The plug-in assembly includes a housing 26, with the housing 26 fixedly connected to the top of the pull plate 25. A plug rod 27 is slidably connected to the inner wall of the housing 26. The bottom end of the plug rod 27 passes through the pull plate 25 and is movably inserted into the plug hole 18. A fixing ring 28 is fixedly connected to the outer wall of the plug rod 27 and slidably connected to the inner wall of the housing 26. A spring 29 is sleeved on the outside of the plug rod 27. The two ends of the spring 29 are fixedly connected to the inner wall of the housing 26 and the outer wall of the fixing ring 28, respectively. The plug-in assembly can restrict the position of the two arc plates 23, thereby ensuring stable clamping of the reagent bottle.

[0049] Through the above structural design, when placing the reagent bottle, the placement cylinder 19 can initially restrict the position of the reagent bottle by receiving it. By pulling up the insertion rod 27, the insertion rod 27 is moved away from the insertion hole 18. During this process, the fixing ring 28 slides inside the housing 26, and the spring 29 deforms accordingly. Then, the insertion rod 27 can pull the pull plate 25, which in turn causes the rotating column 21 to rotate. Then, the gear 20 can change the position of the two racks 22, which in turn causes the two arc plates 23 to move closer to each other. At this time, the two sliding rods 24 slide on the inner wall of the placement cylinder 19, which can further clamp and restrict the reagent bottle. After the reagent bottle is stably clamped, the insertion rod 27 can be released, so that the insertion rod 27 can be inserted into the corresponding insertion hole 18 under the action of the spring force of the spring 29, thus completing the restriction of the reagent bottle.
