Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, specifically relating to an anti-tipping capacity bottle rack. Background Technology

[0002] A volumetric flask is a pear-shaped, flat-bottomed volumetric flask with a narrow neck and a ground glass stopper. It has a graduation mark on the neck indicating that at the specified temperature, when the concave meniscus of the liquid is tangent to the graduation mark on the neck of the flask, the volume of the solution is exactly equal to the volume marked on the flask. Volumetric flasks are marked with: temperature, volume, and graduation marks.

[0003] Since volumetric flasks are usually made of glass and are relatively tall, they are easily bumped and broken during normal storage, which affects their lifespan, increases laboratory expenses, and impacts the user experience.

[0004] To address the aforementioned technical issues, volumetric flask racks have emerged on the market. For example, patent application number CN202220047816.X discloses a collision-resistant glass volumetric flask rack. This rack features a split structure for the flask fixing assembly: side plate one, middle plate, and side plate two. The middle plate is first inserted between the left and right supports, then the volumetric flask is placed inside. Side plates one and two are then inserted between the left and right supports to secure the flask body, effectively ensuring stability during placement or movement. However, in this rack, the flask neck is merely placed within the neck holder without any retaining mechanism. During ultrasonic or other experiments, the neck may detach from the holder and fall over. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the prior art and provide an anti-tipping volumetric flask rack. The structure of the volumetric flask rack has been improved, and a magnetic retaining strip has been added for easy installation. The operation is simple and solves the problems of volumetric flasks easily tipping over, colliding, and falling during experimental activities (such as ultrasound) and movement, greatly improving practicality and safety.

[0006] The technical solution to achieve the above objective is: an anti-tipping capacity bottle rack, comprising a bottom tray, a middle fixing plate, a top fixing plate, two baffles, and two side plates, wherein:

[0007] The two side panels are arranged opposite each other, one on the left and one on the right.

[0008] The bottom support plate, the middle fixing plate and the top fixing plate are arranged between the two side plates from bottom to top, and the ends of the bottom support plate, the middle fixing plate and the top fixing plate are tenon-tenon connected to the inner side of the side plates.

[0009] The distance between the middle fixing plate and the bottom support plate is half the height of the entire volumetric flask.

[0010] The middle layer fixing plate has two rows of bottle-accommodating round holes, one in front of the other, and the diameter of each bottle-accommodating round hole is 1 to 2 mm larger than the maximum diameter of the volumetric bottle.

[0011] The top-level fixing plate has two rows of bottle neck inlets and outlets, one in front of the other, and the two rows of bottle neck inlets and outlets are set one-to-one with the two rows of bottle body receiving holes; each bottle neck inlet and outlet is L-shaped.

[0012] The two baffles are magnetically attached to the two rows of bottleneck inlets and outlets, respectively.

[0013] In the aforementioned anti-tipping capacity bottle rack, the distance between the bottom tray and the bottom end of the side plate is 5mm.

[0014] In the aforementioned anti-tipping capacity bottle rack, the distance between the middle fixing plate and the bottom support plate is 10mm to 15mm.

[0015] In the aforementioned anti-tipping capacity bottle rack, each baffle is evenly distributed with several magnetic rings, and the front and rear parts of the top fixing plate are respectively provided with several grooves, each groove being provided with a magnetic ring. The several magnetic rings on the baffle are magnetically attracted to the corresponding magnetic rings, so that the baffle blocks the corresponding bottle neck inlet and outlet.

[0016] The anti-tipping capacity bottle holder of this utility model has the following beneficial effects:

[0017] (1) A middle fixing plate is provided, and a round hole suitable for the body of the volumetric flask is opened in the middle fixing plate. The distance between the middle fixing plate and the bottom support plate is increased to about half of the body of the volumetric flask, so that the body of the volumetric flask can be well fixed in the round hole and it is not easy to tip over even when moving or carrying out experimental activities.

[0018] (2) A baffle is provided, which is magnetically connected to the top fixing plate. When the volumetric flask is placed or when it is stationary, the baffle is removed. When the volumetric flask rack needs to be moved or an experiment is carried out, the baffle is installed. The volumetric flask will not fall or tip over during the movement or experiment. The operation is simple and safe. Attached Figure Description

[0019] Figure 1 This is a three-dimensional structural diagram of the anti-tipping capacity bottle holder of this utility model. Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments are described in detail below with reference to the accompanying drawings:

[0021] Please see Figure 1The preferred embodiment of this utility model is an anti-tipping capacity bottle rack, which includes a bottom support plate 1, a middle fixing plate 2, a top fixing plate 3, two baffles 4 and two side plates 5.

[0022] The two side panels 5 are positioned opposite each other, one on the left and one on the right.

[0023] The bottom support plate 1, the middle fixing plate 2, and the top fixing plate 3 are arranged sequentially from bottom to top between the two side plates 5, and the ends of the bottom support plate 1, the middle fixing plate 2, and the top fixing plate 3 are mortised and tenoned together with the inner side of the side plate 5; for example, a bottom support plate connecting groove, a middle fixing plate connecting groove, and a top fixing plate connecting groove are opened on the side plate 5, and the ends of the bottom support plate 1, the middle fixing plate 2, and the top fixing plate 3 are inserted into the corresponding connecting grooves to form a mortise and tenon connection.

[0024] The distance between the bottom tray and the bottom of the side panel is 5mm.

[0025] The distance between the middle fixing plate 2 and the bottom support plate 1 is half the height of the entire volumetric flask. Preferably, the distance between the middle fixing plate 2 and the bottom support plate 1 is 10mm (5-10mL volumetric flask) to 15mm (20-25mL volumetric flask).

[0026] The middle fixing plate 2 has two rows of bottle-accommodating round holes 21, one in front and one behind. The diameter of each bottle-accommodating round hole 21 is 1 to 2 mm larger than the maximum diameter of the volumetric bottle body, which can fix the volumetric bottle body.

[0027] The top fixed plate 3 has two rows of neck inlets and outlets 31, one in front of the other. The two rows of neck inlets and outlets 31 are set one-to-one with the two rows of bottle body receiving round holes 21. Each neck inlet and outlet 31 is L-shaped. The neck inlets and outlets 31 facilitate the neck of the volumetric bottle to enter and exit.

[0028] Two baffles 4 are magnetically attached to the two rows of neck inlets and outlets 31 to prevent the neck of the volumetric flask from detaching from the neck inlet and outlet 31 during shaking or other experiments.

[0029] Specifically, each baffle 4 has three magnetic rings 6 evenly distributed on it. The front and rear parts of the top fixing plate 3 are respectively provided with three grooves, and each groove is provided with a magnetic ring 2. The three magnetic rings 6 on the baffle 4 are magnetically attracted to the corresponding magnetic rings 2, so that the baffle 4 is blocked on the corresponding bottleneck inlet / outlet 31. The number of magnetic rings can be adjusted as needed.

[0030] This utility model of an anti-tipping volumetric flask rack allows for easy and safe operation. First, remove the baffle 4 and place the volumetric flask in the rack. When the rack needs to be moved or experiments need to be conducted, reattach the baffle 4. This effectively prevents the volumetric flask from falling or tipping over during movement or ultrasonic experiments.

[0031] In this embodiment, the middle layer fixing plate 2 is an integrated design, consisting of a single piece of plate.

[0032] As an improvement, the middle fixing plate 2 can refer to the split design in the patent with application number CN202220047816.X. For example, the middle fixing plate can be assembled from the front side plate, the middle plate and the rear side plate. The front side plate, the middle plate and the rear side plate are respectively provided with a number of semi-circular slots for accommodating part of the bottle body. By assembling the front side plate, the middle plate and the rear side plate to form a complete bottle body receiving round hole 21, the bottle body of the volumetric bottle is placed in the bottle body receiving round hole 21.

[0033] In summary, this utility model of an anti-tipping volumetric flask rack improves the structure of the volumetric flask rack by adding a magnetic baffle design and increasing the distance between the middle fixing plate and the bottom support plate. The middle fixing plate can fix the position of the volumetric flasks, preventing them from moving significantly during movement or experiments. The baffle can fix the neck of the volumetric flasks, preventing them from moving significantly or tipping over during movement or experiments. The baffle can also be removed when the flask is stationary, making it more convenient for daily laboratory use, greatly improving its practicality and safety, and expanding its application scope.
