Description

Technical Field

[0001] This utility model belongs to the technical field of laboratory equipment, and in particular relates to a bottle stopper holder for volumetric flasks. Background Technology

[0002] A volumetric flask is a long, narrow, pear-shaped, flat-bottomed glass bottle with a ground glass stopper. It has graduations on the neck and is used to prepare solutions of precise molar concentrations. In routine experiments, a large number of volumetric flasks are needed to prepare solutions of specific concentrations. During the experiment, the stopper must be kept uncontaminated to avoid contaminating the solution. Therefore, the placement of the stopper is a key factor affecting the accuracy of solution preparation. Most currently available stopper placement devices connect the stopper to the volumetric flask via a connecting device. This method suffers from problems such as aging at the connection point and the need for frequent cleaning to prevent tangling at the connection.

[0003] Chinese Patent Application No. 202322103303.3 discloses a suspension device for holding bottle stoppers, including a base plate with several hangers on the base plate and several clamping components hanging from the hangers. By using the clamping components, it allows multiple bottle stoppers to be suspended in mid-air, preventing them from contacting other substances and thus avoiding contamination.

[0004] The aforementioned bottle stopper holder relies on clamping components to secure the stoppers, requiring the clamps to be tightened and loosened for removal, which is inconvenient for routine experiments. The device, composed of a base plate, hanging bracket, and clamping components, has a complex structure and occupies a large space, making it unsuitable for use in confined spaces. Furthermore, the numerous components necessitate consideration of their acid and alkali resistance and cost, resulting in high manufacturing costs and hindering widespread adoption. Utility Model Content

[0005] The purpose of this invention is to provide a container for volumetric flask stoppers, addressing the problem of easy contamination when volumetric flask stoppers are placed on a table during experiments. In large-scale testing, volumetric flask stoppers need to be placed individually in a contaminated area to prevent cross-contamination of solutions on the stoppers, which could affect the precise elemental analysis results.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A bottle stopper holder for volumetric bottles includes a support plate that is raised to an elevated position. The support plate is a plate structure and has multiple strip grooves for suspending and supporting the bottle stoppers. The strip grooves have openings on the sides of the support plate, and adjacent strip grooves are staggered on both sides of the support plate.

[0008] The two sides of the groove are used to support the wristbands corresponding to the bottle stopper;

[0009] The bottom of the support plate is a trough, which is used to catch the solution falling from the bottle stopper.

[0010] Furthermore, the support plate has an S-shaped structure with horizontal plates, and adjacent horizontal plates are transitioned by arc-shaped plates, so that the slots corresponding to the strip grooves are arc-shaped open slots.

[0011] Furthermore, the support plate has vertically arranged folding plates on both sides, the support plate and the groove are detachably installed, and the upper edge of the groove has a slot for accommodating and inserting the folding plates.

[0012] Furthermore, the support plate is provided with limiting protrusions on both sides of the strip groove. The protrusions on both sides correspond to the center line of the strip groove and are arranged to extend along the length of the strip groove.

[0013] This invention offers the following advantages: it solves the problem of contamination during bottle stopper placement while providing convenient retrieval and a simple, easy-to-use design. The design utilizes the characteristic of bottle stoppers being wider at the top and narrower in the middle for suspension, allowing the middle part of the stopper to fit into the narrow slit and be placed parallel to the surface. The circular upper part of the stopper fits snugly against the side plates, ensuring the stopper remains suspended and uncontaminated. Simultaneously, the "S"-shaped design maximizes the space available for bottle stoppers, allowing multiple stoppers to be placed in a small area. Different slit widths can accommodate stoppers of varying sizes. The entire device is made of PMMA material, which offers good acid and alkali resistance, is easy to clean, and has low manufacturing costs, making it suitable for production use. Attached Figure Description

[0014] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0015] Figure 1 : Schematic diagram of the structure of this utility model.

[0016] Figure 2 : A schematic diagram of the disassembled structure of the support plate of this utility model.

[0017] The components represented by each number in the attached diagram are listed below: support plate 1, bottle stopper 2, groove 3, strip groove 11, folding plate 12, slot 31, protrusion 13. Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figure 1-2As shown: A bottle stopper rack for volumetric bottles includes a support plate 1 that is set at a height. The support plate 1 is a plate structure. The support plate 1 has multiple strip grooves 11 for suspending and supporting bottle stoppers 2. The strip grooves 11 have openings on the sides of the support plate 1, and the openings of adjacent strip grooves 11 are staggered on both sides of the support plate 1.

[0020] The two sides of the groove 11 are used to support the wristbands corresponding to the bottle stopper 2;

[0021] The bottom of the support plate 1 is a trough 3, which is used to catch the solution falling from the stopper 2. This prevents the solution on the stopper from dripping onto the lab bench and causing contamination.

[0022] The bottle stopper has a frustum-shaped body with a circular wristband on the upper side. The wristband is circular in cross-section and its diameter is larger than the maximum diameter of the stopper. When in use, the wristband is inserted into the groove of the stopper body. The groove of the groove can support the wristband, making the axis of the stopper body vertical and thus suspending it. The groove of the support plate can accommodate multiple bottle stoppers at the same time.

[0023] like Figure 2 As shown: The support plate 1 has an S-shaped structure with horizontal plates. Adjacent horizontal plates are transitioned by arc-shaped plates, making the opening of the slot 11 an open arc-shaped opening. This facilitates the insertion of the bottle stopper from one side of the opening and its movement to the appropriate position within the slot.

[0024] The support plate 1 has vertically arranged folding plates 12 on both sides. The support plate 1 and the groove 3 are detachably installed. The upper edge of the groove 3 has a slot 31 for accommodating and inserting the folding plates 12. This facilitates the overall disassembly of the support plate for cleaning.

[0025] The support plate 1 is provided with limiting protrusions 13 on both sides of the strip groove 11. The protrusions 13 on both sides correspond to the center line of the strip groove 11 and are arranged to extend along the length of the strip groove 11. The adjacent protrusions form a limit to limit the bottle stopper and prevent the bottle stopper from shifting in the corresponding strip groove, colliding with each other and cross-contamination.

[0026] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
