Description

Technical Field

[0001] This application relates to the technical field of colorimetric tubes, and particularly to a colorimetric tube for water quality inspection. Background Art

[0002] A colorimetric tube is the main instrument used in visual colorimetric analysis experiments in chemical experiments. It is a transparent glass tube, usually marked with scales, and can hold liquid samples. It is used to detect the color and concentration changes of solutions and can roughly measure the solution concentration. When performing colorimetry, the colorimetric tube containing the test solution and a colorimetric tube containing the standard solution are placed in front of a white paper with the same illumination level for comparison, and the color difference is observed with the naked eye.

[0003] For the existing colorimetric tubes, after filling with the water quality to be tested, the opening of the colorimetric tube needs to be tightly sealed with a stopper to prevent splashing or contamination inside the colorimetric tube, thereby avoiding affecting the detected data. However, the stopper is tightly set on the colorimetric tube and is generally difficult to pull out. If the force is too small, the stopper will be difficult to pull out. If the force is too large, the water quality to be tested inside the colorimetric tube may splash out due to inertia, and even damage the colorimetric tube, which is time-consuming and laborious and has poor practicability. Therefore, a colorimetric tube for water quality inspection with good sealing effect, time-saving and labor-saving, and strong practicability is proposed. Utility Model Content

[0021] Next, in combination with specific embodiments, the present application will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0022] In the description of the present application, it should be noted that for orientation terms, such as the terms "center", "horizontal", "vertical", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the indicated orientation and position relationships are based on the orientation or position relationships shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily describe a specific order or sequence.

[0024] The terms "including" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0025] One preferred embodiment of the present application is, as Figures 1 to 7 shown, a colorimetric tube for water quality inspection, including a tube body 1 and a tube cap 2. By providing the tube cap 2, it is convenient to tightly plug the open tube body 1, prevent pollution inside the empty tube body 1 or the liquid inside the tube body 1 containing liquid from being polluted or flowing out, and thus facilitate better protection of the seal of the tube body 1 and improve the accuracy of the water quality to be detected; a fixed disk 11 is provided at the top of the tube body 1. By providing the fixed disk 11, it is convenient to stably fix the entire tube body 1. At least one push block 12 is provided at the top of the fixed disk 11. The push block 12 cooperates with the tube cap 2, and the push block 12 and the fixed disk 11 cooperate through a traction structure 3. By providing the push block 12 and the push block 12 and the fixed disk 11 cooperating through the traction structure 3, the traction structure 3 is driven to drive the push block 12 to move upward along the axial direction of the tube body 1. Then, when the push block 12 moves upward, the tube cap 2 abutted against the push block 12 will be pushed, and thus the tube cap 2 will gradually become loose and gradually separate from the opening of the tube body 1, which is convenient to ensure that the tube cap 2 will not cause damage to the tube body 1 when opened, and at the same time ensures the convenience, safety, strong practicability, time-saving and labor-saving of the operation.

[0026] It can be understood that, as Figure 4 and Figure 5 shown, when the traction structure 3 drives the push block 12 to push up the tube cap 2 to loosen it, then it is not necessary to apply a particularly large force to directly pull the tube cap 2, so that the tube cap 2 can be well pulled out from the opening of the tube body 1, and then the tube cap 2 can be pulled out more quickly and safely, which is more simple, fast and time-saving, and at the same time better ensures the safety of the tube body 1.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 6 shown, a mating disc 21 is installed at the top of the tube cap 2, and the mating disc 21 and the fixed disc 11 are connected by a connecting line 22. By providing the connecting line 22, it is convenient to better match the tube cap 2 and the tube body 1, so that the tube body 1 and the tube cap 2 form a set, and then the practicability of the overall device can be better improved.

[0028] In this embodiment, as Figures 3 to 7 shown, it can be understood that the setting method of the push block 12 includes but is not limited to the following two setting methods.

[0029] Setting method one: as Figures 3 to 5 and Figure 6 shown, two push blocks 12 are provided, grooves are opened on both sides of the fixed disc 11, and the two push blocks 12 are slidably arranged in the two symmetrical grooves.

[0030] As Figures 3 to 6 shown, at this time, the traction structure 3 includes an inclined plane block 32 installed at the bottom of the two push blocks 12, and a traction block 31 elastically installed on both sides of the fixed disc 11 through a spring; an inclined plane is provided on the side of the traction block 31, and the inclined planes of the two traction blocks 31 are matched with the inclined planes of the corresponding inclined plane blocks 32; then when the tube cap 2 needs to be opened, at this time, the two traction blocks 31 can be elastically pushed, and the two traction blocks 31 will move along the radial direction of the tube body 1. Then, the movement of the two traction blocks 31 can squeeze the inclined plane of the inclined plane block 32 through the inclined plane of the traction block 31, so that the inclined plane block 32 will move upward along the axial direction of the tube body 1. The upward movement of the inclined plane block 32 can drive the push block 12 to gradually move upward from the groove, and the gradual upward movement of the push block 12 can gradually push the mating disc 21 that abuts against the push block 12. Then, when the mating disc 21 gradually moves, it can drive the tube cap 2 to gradually move upward. At this time, the tube cap 2 will be tightly fitted with the opening of the tube body 1 and will be gradually pushed up and loosened by the push block 12 until the tube cap 2 is separated from the opening of the tube body 1. Then, it is convenient to save time and effort to separate the tube cap 2 from the tube body 1, and effectively prevent the tube body 1 from being damaged due to excessive force, improving the convenience and safety of the operation.

[0031] It can be understood that, asFigures 4 to 5 As shown, in order to prevent the traction block 31 from elastically squeezing the inclined plane block 32, causing the inclined plane block 32 to protrude from the slot opened in the fixed disk 11, a limit block is provided on the side of the inclined plane block 32. Thus, when the inclined plane block 32 moves upward, the inclined plane block 32 cannot completely protrude from the slot, which can better improve the stability and safety of the overall device.

[0032] Setting method two: As Figures 3 to 5 and Figure 7 shown, there are four push blocks 12. Four slots are equidistantly opened on the side of the fixed disk 11, and the four push blocks 12 are slidably arranged in the corresponding slots.

[0033] As Figures 3 to 5 and Figure 7 shown, at this time, the traction structure 3 includes an inclined plane disk 33 installed inside the fixed disk 11, and traction blocks 31 elastically arranged on both sides of the fixed disk 11 through springs; the bottoms of the four push blocks 12 are installed at the top of the inclined plane disk 33, and inclined planes are provided on the sides of the traction blocks 31. The inclined planes of the two traction blocks 31 cooperate with the inclined planes of the corresponding inclined plane disk 33. Thus, when the pipe cap 2 needs to be opened, the two traction blocks 31 can be elastically driven by squeezing the spring at this time. The two traction blocks 31 can move along the radial direction of the pipe body 1. When the two traction blocks 31 move, the inclined planes of the traction blocks 31 can squeeze the inclined planes of the inclined plane disk 33, so that the inclined plane disk 33 will gradually move upward along the axial direction of the pipe body 1. The gradual upward movement of the inclined plane disk 33 can drive the four push blocks 12 to gradually move upward from the slots together. The gradual upward movement of the four push blocks 12 can slowly push the mating disk 21 that abuts against the push blocks 12. Thus, the movement of the mating disk 21 can slowly drive the pipe cap 2 to move upward. At this time, the pipe cap 2 will gradually be pushed up and loosened due to the tight fit with the opening of the pipe body 1 until the pipe cap 2 is gradually separated from the pipe body 1, which is convenient for better separating the pipe cap 2 from the pipe body 1, effectively preventing damage to the pipe body 1 caused by excessive force, and improving the convenience and safety of the operation.

[0034] It can be understood that in setting method one, fewer structures are used, which is convenient for better processing and assembly. However, the push blocks 12 are symmetrically arranged at both ends, and the force on the pipe cap 2 during pushing is relatively concentrated. When pushing the pipe cap 2, the pipe cap 2 may shake; in setting method two, there are four push blocks 12. The four push blocks 12 are equidistantly arranged on the side of the fixed disk 11, and two traction blocks 31 are still used for traction. Thus, when driving, the force on the pipe cap 2 is relatively uniform, which is convenient for more stable upward movement of the pipe cap 2. However, in setting method two, more structures are used, and it is not easy to assemble or process.

[0035] The above two setting methods both meet the requirements of this application, and those skilled in the art can choose according to the actual situation. For the following description, this application adopts Setting Method 1.

[0036] In this embodiment, as Figure 1 and Figure 2 shown, it can be understood that scale lines are provided on the side of the tube body 1, so that measurement and marking can be carried out, facilitating personnel to quickly and accurately read data, thereby improving the relevant work efficiency and accuracy, and ensuring the accuracy and reliability of the experimental results.

[0037] The above describes the basic principle, main features and advantages of this application. Those skilled in the art should understand that this application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed. The scope of protection required by this application is defined by the appended claims and their equivalents.
