Description

Technical Field

[0001] This utility model relates to the field of chemical storage, and in particular to a chemical storage bottle for chemical engineering. Background Technology

[0002] In the field of chemical engineering, storage bottles, as core containers, need to meet the requirements of different chemical properties. Glass storage bottles, with their high corrosion resistance, transparency and chemical stability, are often used for storing high-purity reagents. Plastic bottles are suitable for conventional reagents because they are lightweight and not easily broken. Metal bottles are pressure-resistant and corrosion-resistant. When sealing, cork stoppers are an important choice for sealing storage bottles because of their good elasticity, corrosion resistance and chemical inertness. Their material can fit tightly to the bottle mouth, effectively preventing liquid evaporation and gas leakage, and are especially suitable for storing organic solvents.

[0003] In the current technology, when operators take liquid from the inside of a chemical storage bottle, they usually use a dropper to probe into the storage bottle and then use the dropper to take out the liquid. However, during this process, the outer wall of the dropper will be contaminated with chemical liquid, causing the chemical liquid to drip into the outside while the dropper is being moved, creating a safety hazard. To address this issue, a chemical storage bottle for chemical engineering is proposed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a chemical storage bottle for chemical engineering, which aims to improve the problem in the prior art that "when using a dropper to take out the internal liquid, the outer wall of the dropper will be contaminated with chemical liquid during the process, causing the chemical liquid to drip into the outside during the movement of the dropper, creating a safety hazard".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chemical storage bottle for chemical engineering, comprising a bottle body, a cork movably connected to the upper part of the inner wall of the bottle body, a removal assembly provided on the upper part of the outer wall of the bottle body, and a scraping assembly provided on the inner wall of the bottle body; the scraping assembly includes a spring piece, the upper part of the outer wall of the spring piece being inserted into the upper part of the inner wall of the bottle body, a fixing ring fixedly connected to the lower surface of the spring piece, multiple sets of support rods fixedly connected to the inner wall of the fixing ring, a scraping ring fixedly connected to the end of the support rod away from the fixing ring, a pull ring fixedly connected to the end of the spring piece away from the inner wall surface of the bottle body, and a retaining ring fixedly connected to the upper part of the inner wall of the bottle body, the upper surface of the retaining ring contacting the lower surface of the fixing ring.

[0006] As a further description of the above technical solution:

[0007] The scraping ring is a cone shape that gradually tapers from top to bottom.

[0008] As a further description of the above technical solution:

[0009] The spring is L-shaped.

[0010] As a further description of the above technical solution:

[0011] The removal assembly includes a support ring, the lower surface of which is fixedly connected to the upper part of the outer wall of the bottle, and the upper surface of which is fixedly connected with multiple sets of fixing rods.

[0012] As a further description of the above technical solution:

[0013] A top ring slides on the upper part of the outer wall of the fixed rod, and a swing rod is hinged to the inner wall of the fixed rod.

[0014] As a further description of the above technical solution:

[0015] The left side of the swing rod is hinged to a top rod, and the upper part of the top rod is hinged to the lower part of the outer wall of the top ring.

[0016] As a further description of the above technical solution:

[0017] A pressing plate is fixedly connected to the end of the fixed rod away from the top rod.

[0018] As a further description of the above technical solution:

[0019] The upper surface of the retaining ring is in contact with the lower surface of the fixing ring.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the scraping component allows the operator to use a dropper to take liquid from the storage bottle. During this process, the outer wall of the dropper will come into contact with the scraping ring, causing the chemical liquid adhering to the outer wall of the dropper to be scraped off into the storage bottle, preventing the liquid from dripping onto the outside. At the same time, tweezers can be used to hold the two pull rings, making it easier to remove the entire component and preventing the liquid from remaining on the surface of the scraping ring when pouring liquid into the storage bottle.

[0022] 2. In this utility model, when the cork is tightly plugged, the operator may use too much force when pulling it out, causing the bottle to shake and spill the liquid inside. At this time, the operator can press down on the push plate. During the operation of the pull-out component, it will continuously apply a downward force to the bottle, making the bottle firmly contact the table or other flat surface. At the same time, the swing rod is a force-saving lever, which allows the operator to pull out the cork more easily. Attached Figure Description

[0031] Reference Figures 1-3The end of the spring piece 31 away from the inner wall surface of the bottle body 1 is fixedly connected to a pull ring 35 for easy movement of the spring piece 31 by the operator. The upper part of the inner wall of the bottle body 1 is fixedly connected to a retaining ring 36 to prevent the retaining ring 32 from falling off. The upper surface of the retaining ring 36 is in contact with the lower surface of the retaining ring 32. The scraping ring 34 is a cone shape that gradually narrows from top to bottom. The spring piece 31 is set in an L shape so that the horizontal part of the spring piece 31 is inserted into the bottle body 1, making the spring piece 31 and the bottle body 1 more tightly fixed. The removal assembly 4 includes a support ring 41 for supporting the retaining rod 42. The lower surface of the support ring 41 is fixedly connected to the upper part of the outer wall of the bottle body 1.

[0032] Reference Figures 1-3 The upper surface of the support ring 41 is fixedly connected to a fixed rod 42 for supporting the swing of the fixed rod 42, and there are multiple sets of fixed rods 42. The upper part of the outer wall of the fixed rod 42 is slidably connected to a top ring 46 for lifting the cork 2. The inner wall of the fixed rod 42 is hinged to a swing rod 43. The left part of the swing rod 43 is hinged to a top rod 44 for driving the top ring 46 to move up or down.
