Description

Technical Field

[0001] This utility model relates to the field of support technology, specifically to a volumetric bottle support. Background Technology

[0002] A volumetric flask, also called a volumetric flask, is a precision measuring instrument used to prepare solutions of a specific volume and concentration. It is one of the most commonly used containers in chemical testing and inspection laboratories. In analytical testing, volumetric flasks are generally used to dilute standard substances and extracts from test samples to the required volume.

[0003] Volumetric flasks are pear-shaped, flat-bottomed containers with narrow necks, fitted with frosted glass or plastic stoppers. A circular mark is engraved on the neck to indicate the volume to which the liquid has been diluted. The narrow neck facilitates dilution, and the flat bottom makes them easy to move on a table. Common sizes for volumetric flasks are 5mL, 10mL, 25mL, 50mL, 100mL, 200mL, 250mL, 500mL, 1000mL, 2000mL, and 5000mL. Small volumetric flasks (5mL to 250mL) are the most widely used and numerous in laboratories. However, due to their taller body and smaller flat bottom, they are slow to dilute in batches, inconvenient to move, and prone to tipping during experiments.

[0004] Patent application number 201020241712X discloses a volumetric flask holder, which includes a side plate and a base plate and a positioning plate fixed to the side plate. The positioning plate is divided into upper and lower layers. This design can facilitate batch volumetric flask determination and movement by the operator while fixing the volumetric flasks, thus speeding up the experiment, saving time, and is simple and practical. However, it uses an "L"-shaped opening on the side of the upper positioning plate and regular through holes in the lower positioning plate, which correspond to the "L"-shaped opening. Although it can quickly place volumetric flasks, the "L"-shaped opening has poor limiting effect, so two flasks will still shake during the transfer process, posing a risk that the neck of the flask will detach from the "L"-shaped opening, resulting in low safety.

[0007] The lower shelf has an edge frame one on its lower edge, and the upper shelf has an edge frame two on its lower edge.

[0008] A sliding guide mechanism is provided between the upper shelves, allowing the upper shelves to move up and down relative to the lower shelves. A snap-fit ​​mechanism is provided between the upper shelves and the lower shelves.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Example 1, in conjunction with Appendix Figure 1-2A volumetric flask support includes an upper shelf 1 and a lower shelf 2. The upper shelf 1 is provided with an array of upper limit holes 3, and the lower shelf 2 is provided with an array of lower limit holes 4. The number of upper limit holes 3 and lower limit holes 4 are the same and correspond one-to-one. The corresponding upper limit holes 3 and lower limit holes 4 are coaxial. The diameter of the upper limit holes 3 is matched with the diameter of the neck of the volumetric flask, and the diameter of the lower limit holes 4 is smaller than the maximum diameter of the body of the volumetric flask.

[0018] The lower shelf 2 has an edge frame 5 on its lower edge, and the upper shelf 1 has an edge frame 6 on its lower edge.

[0019] A sliding guide mechanism is provided between the upper shelf 1 and the lower shelf 2, and the upper shelf 1 can move up and down relative to the lower shelf 2. A buckle mechanism is provided between the upper shelf 1 and the lower shelf 2.

[0020] The sliding guide mechanism includes a sleeve 7 symmetrically arranged along the middle of the upper shelf 1 and fixed above the upper shelf 1, a slide rod 8 slidably connected to the sleeve 7, and a spring disposed in the sleeve 7. The upper end of the slide rod 8 is fixedly connected to the upper shelf 1, one end of the spring is fixedly connected to the lower shelf 2, and the other end of the spring is fixedly connected to the slide rod 8.

[0021] The buckling mechanism includes a connecting rod 9 and a push-type buckle 10 located between the connecting rod 9 and the lower frame 2.

[0022] In use, firstly, the press-type buckle 10 separates. Under the action of the spring force, the distance between the upper shelf 1 and the lower shelf 1 is large, allowing the volumetric flask to be placed in the corresponding lower limit hole 4 position. After placing the volumetric flask, press down on the upper shelf 1, and the upper limit hole 3 fits onto the neck of the volumetric flask. When you continue to press down on the upper shelf 1, the two parts of the press-type buckle 10 are fastened together. At this time, after releasing the force from the upper shelf 1, the upper shelf 1 will not move upward, achieving simultaneous upper and lower limit. When you need to retrieve the volumetric flask, simply press down on the upper shelf 1. After releasing the force, the two parts of the press-type buckle 10 automatically separate, and the upper shelf 1 moves upward to the designed movable distance under the action of the spring force, at which point the volumetric flask can be retrieved.
