Description

Technical Field

[0001] The present application relates to the technical field of liquid measurement, and in particular to a stainless steel protective device for a glass calibration cylinder. Background Art

[0002] The calibration cylinder and the measuring cylinder are containers for the measured liquid that are often used in the process of measuring the physical or chemical indicators of the measured liquid. However, the difference between the calibration cylinder and the measuring cylinder is that the calibration cylinder has no graduation scale on the surface, and is simply used to hold the measured liquid, which is convenient for multi-directional readings; while the measuring cylinder has a graduation scale on the surface, which affects the multi-directional readings, so the calibration cylinder is often used to hold the measured liquid. The main material of the commonly used calibration cylinders now is glass, and a few (especially those often taken outdoors for field measurements) are made of stainless steel or transparent plastic.

[0003] In the prior art, the calibration cylinder made of glass, stainless steel or transparent plastic alone may have the following risks during use:

[0004] A calibration cylinder with only a glass layer: Although a glass calibration cylinder is convenient for using a standardized and correct measurement method to obtain a high-accuracy measurement result, it is not suitable for outdoor field measurements because glass is extremely fragile (for example, in the wine industry, when outdoor wine delivery, wine collection, and wine extraction during production require measurement of wine concentration and temperature). Using a calibration cylinder made of glass has the safety risk of the glass calibration cylinder falling over and breaking;

[0005] Calibration cylinder made of stainless steel: Although the calibration cylinder made of stainless steel is not easy to fall over and break during use, due to its opaque characteristics, it is impossible to use the correct measurement method and reading method to obtain readings during the measurement process, resulting in the measurement results being too low or too high, and the accuracy is low, thus affecting the output and quality;

[0006] Calibration cylinder made of plastic: Calibration cylinder made of plastic is not easy to fall over and break during use, but due to its low transparency, the measurement results obtained may be too low or too high, with low accuracy, and there may even be food safety risks for edible liquids being tested.

[0007] In summary, there is an urgent need to provide a stainless steel protection device for a glass calibration cylinder to solve the technical problems raised above. Utility Model Content

[0028] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined with each other and quoted from each other without contradiction.

[0029] Please refer to Figure 1-Figure 3 As shown, a glass calibration cylinder stainless steel protection device provided in this embodiment is described in detail below in conjunction with the accompanying drawings. The glass calibration cylinder stainless steel protection device is used for the calibration cylinder bottle body 1, the calibration cylinder bottle body 1 is made of transparent glass and is provided with a liquid level observation area 11, the glass calibration cylinder stainless steel protection device includes a protection cylinder 2, the protection cylinder 2 is mounted on the outer layer of the calibration cylinder bottle body 1, and the protection cylinder 2 can expose or cover the liquid level observation area 11; when in use, the protection cylinder 2 can expose the liquid level observation area 11; when not in use, the protection cylinder 2 can cover the liquid level observation area 11.

[0030] In this embodiment, a protective cylinder 2 is mounted on the outer layer of a calibration cylinder body 1 made of transparent glass material, and the protective cylinder 2 is used to protect the calibration cylinder body 1 made of transparent glass material. When the calibration cylinder body 1 is needed to hold a measured liquid for physical or chemical index measurement, the measured liquid is placed in the calibration cylinder body 1. When in use, the liquid level observation area 11 can be exposed by operating the protective cylinder 2. Then, after the measuring instrument is placed in the calibration cylinder body 1 and stabilized, the corresponding measurement operation is performed. The measured liquid can be clearly observed and the measurement result can be read through the liquid level observation area 11. After completing the corresponding measurement operation, the protective cylinder 2 can be restored to its original state by operating it again. That is, when not in use, the protective cylinder 2 can cover the liquid level observation area 11, thereby protecting the calibration cylinder body 1. Therefore, in this embodiment, the use of the protective cylinder 2 can ensure the acquisition of high-precision measurement results while avoiding the risk of the glass calibration cylinder bottle 1 being knocked over and broken, and also avoiding the quality risks and food safety risks caused by using the calibration cylinder bottle 1 made of other materials.

[0031] In this embodiment, it should be noted that there is no graduation scale on the calibration cylinder bottle body 1 made of transparent glass, so the measured liquid and the readings of the measuring instrument can be clearly observed through the glass. Moreover, the cylinder body 1 is smooth and transparent, and the surface in direct contact with the measured liquid is made of glass, so there is no food-grade safety risk.

[0032] Please continue to refer to Figure 1-Figure 3As shown, in this embodiment, it should be noted that the protective cylinder 2 is made of stainless steel, and the protective cylinder 2 can be made according to the shape of the test cylinder bottle 1 by utilizing the ductility of the stainless steel. Preferably, the stainless steel is food grade stainless steel.

[0033] In an achievable manner, the protective cylinder 2 includes a fixed cylinder 21, a sliding cylinder 22, a base 23 and a protective layer fixing plate 24. The bottom end of the fixed cylinder 21 is integrally connected to the base 23. The cross-sectional area of ​​the base 23 is larger than the cross-sectional area of ​​the fixed cylinder 21. Then, the support of the base 23 has a certain stability, which can ensure that the calibration cylinder bottle 1 filled with the measured liquid can be placed stably on a horizontal plane during the measurement process and is not easy to fall over and break. The sliding cylinder 22 is sleeved on the outer layer of the fixed cylinder 21 and can be slidably arranged on the fixed cylinder 21. The lower end of the calibration cylinder bottle 1 is sleeved on the inner layer of the fixed cylinder 21. The upper end of the calibration cylinder bottle 1 extends out of the fixed cylinder 21, and the upper half is set as a liquid level observation area 11. Then, by sliding the sliding cylinder 22 up and down, the liquid level observation area 11 can be covered or exposed, thereby protecting the entire calibration cylinder bottle 1.

[0034] The protective layer fixing plate 24 is integrally connected to the upper end of the fixed cylinder 21 and extends in a direction parallel to the axis of the fixed cylinder 21. The upper end of the protective layer fixing plate 24 extends to be flush with the upper end of the calibration cylinder body 1. The protective layer fixing plate 24 is located between the calibration cylinder body 1 and the sliding cylinder 22. The protective layer fixing plate 24 is mainly used to fix the sliding cylinder 22 after it slides to a fixed position. A locking piece is provided on the protective layer fixing plate 24, and the locking piece is used to lock the position of the sliding cylinder 22 sliding on the protective layer fixing plate 24. By providing the protective layer fixing plate 24 between the calibration cylinder body 1 and the sliding cylinder 22, the position of the sliding cylinder 22 can be fixed by the action of the locking piece when the sliding cylinder 22 slides to the liquid level observation area 11 covering the calibration cylinder body 1.

[0035] In one example, the locking member includes a spring jumping bean 25, and the sliding cylinder 22 is provided with a first hole 221 and a second hole 222 that cooperate with the spring jumping bean 25, wherein the first hole 221 is close to the top position of the sliding cylinder 22, and the second hole 222 is close to the bottom position of the sliding cylinder 22; thus, when the sliding cylinder 22 is in the initial position, that is, the sliding cylinder 22 can completely cover the liquid level observation area 11, the spring jumping bean 25 cooperates with the second hole 222; when the sliding cylinder 22 slides to the working position, that is The sliding cylinder 22 can expose the liquid level observation area 11, and the spring jumping bean 25 cooperates with the first hole 221. Then, in this embodiment, the position of the sliding cylinder 22 can be fixed by using the spring jumping bean 25 to cooperate with the first hole 221 and the second hole 222. The structure of the spring jumping bean 25 is also convenient for operation. When the sliding cylinder 22 needs to be operated, it is only necessary to press the spring jumping bean 25 and press the spring jumping bean 25 into the first hole 221 or the second hole 222 to release the restriction on the sliding cylinder 22.

[0036] Preferably, the first hole position 221 and the second hole position 222 are on the same vertical line, so that the sliding cylinder 22 can be locked or unlocked straight up and down along the protective layer fixing plate 24, which is convenient for operation.

[0037] When it is necessary to read the physical or chemical index readings of the measured liquid, press the spring jumping bean 25 to make the spring jumping bean 25 enter the second hole 222. At this time, the sliding cylinder 22 can be pulled down along the protective layer fixing plate 24 to a fixed position, and the standard reading method can be used to read the calibration cylinder bottle body 1. After the measurement and reading are completed, press the spring jumping bean 25 again to make the spring jumping bean 25 enter the first hole 221. At this time, pull the sliding cylinder 22 up along the protective layer fixing plate 24 to the second hole 222 and align it with the spring jumping bean 25. At this time, the spring jumping bean 25 pops out and resets, and then the sliding cylinder 22 is fixed on the protective layer fixing plate 24. This facilitates reading while also protecting the glass calibration cylinder bottle body 1.

[0038] Please continue to refer to Figure 1-Figure 3As shown, in this embodiment, in order to improve the stability of the sliding cylinder 22, two protective layer fixing plates 24 are provided in this embodiment, and the two protective layer fixing plates 24 are spaced apart along the circumferential direction of the fixed cylinder 21. Preferably, the two protective layer fixing plates 24 are symmetrically distributed along the radial direction of the fixed cylinder 21. At the same time, the spring jumping beans 25 provided on the sliding cylinder 22 also correspond to the protective layer fixing plates 24, that is, one protective layer fixing plate 24 corresponds to one spring jumping bean 25. Therefore, when the sliding cylinder 22 needs to slide, the spring jumping beans 25 on both sides are manually pressed so that the sliding cylinder 22 can slide up and down along the protective layer fixing plates 24. When the spring jumping beans 25 are at the fixed position, they pop out and fix the sliding cylinder 22.

[0039] Please refer to Figure 2 , Figure 4 As shown, in this embodiment, it should also be noted that the bottle mouth of the test cylinder bottle body 1 is provided with an adapted bottle cap 12, and the bottle cap 12 is covered on the bottle mouth of the test cylinder bottle body 1. The bottle cap 12 is effectively matched with the bottle mouth of the test cylinder bottle body 1, which can play a role in dust and pollution prevention. In one example, the bottle cap 12 is made of stainless steel, and the stainless steel material is also food grade stainless steel.

[0040] The implementation principle of this embodiment is as follows: a protective cylinder 2 is added to a calibration cylinder bottle body 1 made of transparent glass. When the calibration cylinder bottle body 1 is needed to hold the measured liquid for physical or chemical index measurement, the measured liquid is loaded into the calibration cylinder bottle body 1, the spring jumping bean 25 is pressed, the sliding cylinder body 22 is pulled down to a certain position, the spring jumping bean 25 pops out to fix it, the measuring instrument is placed in the calibration cylinder bottle body 1 and after it is stable, the corresponding measurement operation is performed. After completing the corresponding measurement operation, the spring jumping bean 25 is pressed again to reset the sliding cylinder body 22 to its original position, the spring jumping bean 25 pops out to fix it. After each measurement is completed, the bottle cap 12 should be used to cover it to prevent contamination. After using the calibration cylinder bottle body 1, it should be maintained in time according to the situation. For example, if strong acid, strong alkali or easily corrosive chemical reagents are used, they need to be rinsed clean to reduce damage to the calibration cylinder bottle body 1 and the protective cylinder body 2.
