Description

Technical Field

[0001] This utility model relates to the field of hazardous waste harmless treatment technology, and in particular to a safety bottle opener for identifying unknown reagents. Background Technology

[0002] In the hazardous waste harmless treatment technology industry, many different types of chemical reagents are collected from various universities every year. Among them are many different types of unidentified reagents (unlabeled reagents), mainly in 500ml glass and plastic bottles. These reagents are diverse, complex in composition, and highly pure. For the subsequent harmless treatment of these unidentified reagents, they need to be opened, identified, and tested before disposal. Technicians need to use their hands, tweezers, or scissors to open and identify each bottle individually.

[0003] Since most unidentified reagents are stored for extended periods, their internal components undergo a series of chemical reactions due to prolonged storage and changes in environmental temperature, humidity, and light, including decomposition, volatilization, deliquescence, sublimation, oxidation, and reduction. This can lead to gas expansion and accumulation inside the reagent bottle, potentially causing splashing, spraying, or explosion when the bottle is opened. When personnel attempt to open and identify these unidentified reagents, safety accidents may occur due to splashing, spraying, or explosions. Therefore, a safe bottle opener for identifying unidentified reagents is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that safety accidents may occur when opening and identifying reagent bottles containing unknown reagents due to reagent splashing, spraying or exploding. Therefore, a safe bottle opener for identifying unknown reagents is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: a safety bottle opener for identifying unknown reagents, comprising a protective cover, a transparent plate on the front side of the protective cover, a door hinged to the rear side of the protective cover, a clamping mechanism for clamping and positioning the reagent bottle at the bottom of the protective cover, and a cap removal mechanism for removing the bottle cap and a stopper removal mechanism for removing the inner stopper of the reagent bottle via a fixed base on the top of the protective cover.

[0006] As a further description of the above technical solution: the clamping mechanism includes clamping plates set on both sides of the reagent bottle by screws, the end of the screw located outside the protective cover is provided with a handle, and the clamping plates are provided with guide rods that penetrate the protective cover.

[0008] The buffer assembly includes a gasket disposed on a fixed plate, and a first spring is disposed between the fixed plate and the inner wall of the mounting groove.

[0009] As a further description of the above technical solution: the fixing plate is provided with a positioning rod that penetrates the clamping plate, and the positioning rod is provided with a locking nut that abuts against the clamping plate through a threaded end.

[0010] As a further description of the above technical solution: the cap-removing mechanism includes a hollow connecting rod with a threaded section that passes through the fixed base. A fixed claw is provided at the bottom of the connecting rod, and a movable claw that cooperates with the fixed claw is hinged to the fixed claw. A spring is provided between the movable claw and the bottom of the connecting rod. A rocker arm is provided at the top of the connecting rod. A handle is hinged to the top of the connecting rod below the rocker arm, and a pull rope is provided between the handle and the movable claw. A limiting component for limiting the handle is provided on the rocker arm.

[0011] As a further description of the above technical solution: the limiting component includes a limiting plate that is hinged to the rocker arm via a hinge seat, and the limiting plate has a plurality of limiting grooves that cooperate with the end of the grip.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-9This embodiment provides a safety bottle opener for identifying unknown reagents, including a protective cover 1, a transparent plate 2 on the front side of the protective cover 1, a door 3 hinged to the rear side of the protective cover 1, a clamping mechanism 4 for clamping and positioning the reagent bottle at the bottom of the protective cover 1, and a cap removal mechanism 6 for removing the bottle cap and a stopper removal mechanism 7 for removing the inner stopper of the reagent bottle via a fixing seat 5 on the top of the protective cover 1.

[0028] In this invention, the protective cover 1 is fixed at the reagent identification and testing site. When it is necessary to open and identify an unknown reagent, the cover door 3 is first opened, and the reagent bottle to be identified is placed inside the protective cover 1. Then, the clamping mechanism 4 is used to clamp and fix the reagent bottle, keeping it fixed inside the protective cover 1. After that, the cover door 3 is closed, and the situation inside the protective cover 1 can be observed through the transparent plate 2 on the protective cover 1. Then, the operator can use the cap removal mechanism 6 and the stopper removal mechanism 7 on the fixing base 5 to remove the cap and the inner stopper of the reagent bottle in sequence. This avoids the situation where the unknown reagent splashes or explodes and injures the operator during the operation, effectively improves work safety, solves the unsafe problem of opening unknown reagents, effectively protects the operator, improves the safety of the operator's operation, and prevents the splash of unknown reagents from injuring the operator.

[0029] It should be noted that the transparent panel 2 is made of transparent, rigid, fire-resistant plastic material such as PC or PVC. Under safe conditions, the operator can clearly observe the operation of the reagent bottles inside the protective cover 1 through the transparent panel 2. The cover door 3 is equipped with a handle for operating the cover door 3.

[0030] Specifically, such as Figure 3 and Figure 4 As shown, the clamping mechanism 4 includes clamping plates 41 mounted on both sides of the reagent bottle via screws 42. A handle 43 is provided at one end of the screw 42 located outside the protective cover 1, and a guide rod 44 is provided on the clamping plate 41 that penetrates the protective cover 1.

[0031] The protective cover 1 has an annular base inside that mates with the reagent bottle. When the reagent bottle is placed on the base inside the protective cover 1, the operator uses the handle 43 to rotate the screw 42, causing the screw 42 to move forward on the protective cover 1. The moving screw 42 pushes the clamping plate 41 to move linearly under the guidance of the guide rod 44, thereby clamping and fixing the reagent bottle inside the protective cover 1 through the two clamping plates 41, ensuring that the reagent bottle will not move or rotate during cap removal and stopper removal operations.

[0032] Specifically, such as Figure 4 and Figure 5As shown, a buffer assembly 45 is provided on the side of the clamping plate 41 facing the reagent bottle through the mounting groove. The buffer assembly 45 includes a gasket 452 provided on the fixing plate 451. A first spring 454 is provided between the fixing plate 451 and the inner wall of the mounting groove. A positioning rod 453 is provided on the fixing plate 451 that penetrates the clamping plate 41, and a locking nut 456 is provided on the positioning rod 453 through a threaded end 455 that abuts against the clamping plate 41.

[0033] The positioning rod 453 on the fixing plate 451 passes through the clamping plate 41 and is then limited in the mounting groove of the clamping plate 41 by the locking nut 456 on the threaded end 455. The gasket 452 on the fixing plate 451 is made of rubber and protrudes from the outer side of the clamping plate 41. When the clamping plate 41 approaches the reagent bottle and clamps the reagent bottle, the gasket 452 will contact the surface of the reagent bottle first. As the clamping plate 41 moves, it clamps and fixes the reagent bottle. After clamping, the gasket 452 and the first spring 454 work together to achieve buffering, thereby ensuring the stability of the reagent bottle between the clamping plates 41 when vibration occurs. Moreover, when it is necessary to replace or repair the buffer assembly 45, it is only necessary to remove the locking nut 456 on the threaded end 455, and then the buffer assembly 45 can be removed from the clamping plate 41. It is simple and convenient, and facilitates the maintenance and repair of the buffer assembly.

[0034] Specifically, such as Figure 3 , Figures 6-8 As shown, the cap-removing mechanism 6 includes a hollow connecting rod 61 with a threaded section that passes through the fixed base 5. A fixed claw 62 is provided at the bottom of the connecting rod 61, and a movable claw 63 that cooperates with the fixed claw 62 is hinged to the fixed claw 62. A spring 64 is provided between the movable claw 63 and the bottom of the connecting rod 61. A rocker arm 65 is provided at the top of the connecting rod 61. A handle 66 is hinged to the top of the connecting rod 61 below the rocker arm 65, and a pull rope 68 is provided between the handle 66 and the movable claw 63. A limiting component 67 for limiting the handle 66 is provided on the rocker arm 65. The limiting component 67 includes a limiting plate 672 that is hinged to the rocker arm 65 through a hinge base 671. The limiting plate 672 has several limiting grooves 673 that cooperate with the end of the handle 66.

[0035] During the reagent bottle opening operation, the operator squeezes the handle 66, which pulls the movable claw 63 to close via the pull rope 68. This, in turn, works with the fixed claw 62 to clamp the bottle cap. Then, the operator rotates the limiting plate 672 on the hinge seat 671, causing the end of the handle 66 to engage in the limiting groove 673 of the limiting plate 672. At this point, the operator can release the handle 66. Under the action of the limiting component 67, the handle 66 is prevented from resetting, thus ensuring that the fixed claw 62 and the movable claw 63 clamp the bottle cap. The operator then uses the rocker arm 65 to rotate the connecting rod 61. With the cooperation of the threaded section on the connecting rod 61 and the fixed seat 5, the connecting rod 61 moves upward, thereby driving the fixed claw 62 and the movable claw 63 to unscrew the bottle cap. When the limiting component 67 is opened, the movable claw 63 resets and opens under the action of the spring 64, and the bottle cap falls off, completing the cap removal operation.

[0036] Specifically, such as Figure 3 , Figure 6 and Figure 9 As shown, the plug removal mechanism 7 includes a needle mounting rod 71 that passes through the connecting rod 61. The bottom of the needle mounting rod 71 is provided with a puncture head 72 located below the connecting rod 61. The top of the needle mounting rod 71 is provided with a second spring 73 that abuts against the upper end of the connecting rod 61 via a pull ring 74.

[0037] When the cap removal mechanism 6 completes the cap removal operation of the reagent bottle, the operator presses down the needle mounting rod 71. After the needle mounting rod 71 compresses the second spring 73, the puncture head 72 at its bottom penetrates the inner stopper of the reagent bottle. Then, the pull ring 74, in conjunction with the reset force of the second spring 73, causes the needle mounting rod 71 to drive the puncture head 72 to reset upward, thereby causing the puncture head 72 to pull the inner stopper out of the reagent bottle, completing the cap removal operation.

[0038] It should be noted that the connecting rod 61 is hollow, and the diameter of the needle mounting rod 71 is relatively small compared to the diameter of the connecting rod 61. The pull rope 68 between the handle 66 and the movable claw 63 passes through the connecting rod 61. When the pull rope 68 is inside the connecting rod 61, it bypasses the needle mounting rod 71, and the surface of the needle mounting rod 71 is smooth. Therefore, when performing the plug removal operation, the pull rope 68 inside the connecting rod 61 will not interfere with the movement of the needle mounting rod 71.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
