Description

Technical Field

[0001] The invention belongs to the technical field of experimental instrument physiognomy, and in particular relates to a cuvette installation mechanism. Background Art

[0002] The detection of the total phosphorus content in the sample is usually achieved by using a spectrophotometer. When the spectrophotometer is working, the spectrophotometer will emit a beam of light to the cuvette to illuminate the sample in the cuvette, and the light beam passing through the cuvette will be received by the corresponding receiver. Then, by analyzing the received light beam, the detection purpose of the total phosphorus content in the sample in the cuvette can be obtained.

[0003] It is understandable that the spectrophotometer needs to drive the cuvette to rotate one circle during the process of irradiating the cuvette. The smoothness of the cuvette surface will directly affect the light transmittance of the cuvette, and the light transmittance of the cuvette will have a certain impact on the experimental data finally measured during the analysis of the light beam received by the receiver.

[0004] Currently, the existing cuvette mounting mechanism for clamping the cuvette usually does not have a structure for wiping the outer wall of the cuvette placed therein, which makes it easy for the cuvette to be adsorbed by impurities such as dust on the outer wall, which affects the smoothness of the outer surface of the cuvette, thus affecting the accuracy of the quantity finally detected. Summary of the invention

[0005] Based on this, it is necessary to provide a cuvette mounting mechanism to address the technical problems existing in the prior art.

[0006] A cuvette mounting mechanism comprises a detection cavity, a bearing, a guide ring, a barrel frame, a cotton ring and an adjustment ring, wherein the guide ring is rotatably mounted on the cavity top of the detection cavity through the bearing, so that the guide ring can rotate relative to the detection cavity;

[0007] The guide ring partially extends out of the cavity top of the detection cavity, and the barrel rack is detachably mounted on the portion of the guide ring extending out of the cavity top; the adjustment ring is threadedly mounted on the barrel rack at one end away from the guide ring, the adjustment ring is arranged opposite to the guide ring, and the adjustment ring can cooperate with the guide ring and clamp the cotton ring; wherein, the inner diameter of the cotton ring is smaller than the inner diameter of the guide ring.

[0008] In one of the embodiments, the adjustment ring can move toward the guide ring, and can cooperate with the guide ring and open the cotton ring.

[0009] In one embodiment, a first inclined surface is provided on one end of the guide ring facing the adjustment ring, and a second inclined surface matching the first inclined surface is provided on one end of the adjustment ring facing the guide ring. The guide ring and the adjustment ring can cooperate and clamp the cotton ring through the first inclined surface and the second inclined surface.

[0010] In one embodiment, the cotton loop includes an elastic loop and a non-woven fabric, and the non-woven fabric is arranged to wrap the elastic loop.

[0011] In one of the embodiments, the barrel rack and the guide ring are connected and fixed by means of threads, and the barrel rack can be placed flat on the cavity top of the detection cavity.

[0012] In one of the embodiments, the adjustment ring partially extends out of the barrel frame and is formed with a screwing portion, and the screwing portion can drive the adjustment ring to rotate relative to the barrel frame to adjust the installation position of the adjustment ring on the barrel frame.

[0013] In one of the embodiments, a working hole is opened on the peripheral wall of the barrel rack, and the cotton ring can pass through the working hole and be placed on the guide ring.

[0014] In one of the embodiments, the cuvette mounting mechanism further includes a cotton ring adjustment plate, and the cotton ring adjustment plate can drive the cotton ring to separate from the guide ring in a direction away from the guide ring, so as to adjust the position of the cotton ring relative to the guide ring.

[0018] The present application also seeks to protect a spectrophotometer, comprising any of the above-mentioned cuvette mounting mechanisms.

[0019] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0020] The cuvette mounting mechanism of the present invention has a reasonable structural arrangement, so that when the cuvette is installed on the cuvette mounting mechanism, the cuvette needs to pass through the cotton ring and be placed in the guide ring. During this process, the cotton ring can wipe the outer wall of the cuvette, thereby ensuring the smoothness of the outer surface of the cuvette, which can improve the accuracy of the data obtained when the experimental equipment using the cuvette mounting mechanism is working; at the same time, the inner diameter of the cotton ring can be adaptively adjusted by adjusting the position of the adjustment ring on the barrel rack, which not only facilitates the adjustment of the inner diameter of the cotton ring to meet the use requirements of wiping the outer wall of the cuvette with the cotton ring, but also ensures the stability of the cotton ring installed between the guide ring and the adjustment ring.

Specific embodiments

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] like Figure 1 As shown, the cuvette installation mechanism provided in one embodiment of the present application includes a detection chamber 10 , a bearing 20 , a guide ring 30 , a barrel frame 40 , a cotton ring 50 and an adjustment ring 60 .

[0028] Among them, the guide ring 30 is rotatably mounted on the cavity top 11 of the detection cavity 10 through the bearing 20, so that the guide ring 30 can rotate relative to the detection cavity 10. It should be noted that the guide ring 30 of the present application is used to accommodate and clamp the cuvette (not shown in the figure), and specifically, a loose fit can be adopted to achieve the clamping of the cuvette, so that the cuvette installation mechanism can drive the cuvette placed in the guide ring 30 to rotate relative to the detection cavity 10 when working, so that the cuvette installation mechanism can meet the use requirements of the total phosphorus content detection in the sample in the cuvette in the experimental equipment. Of course, the cuvette installation mechanism is not limited to the detection of the total phosphorus content in the sample contained in the cuvette, and can also be used for the detection of the content of other substances in the sample in the cuvette, which will not be elaborated here.

[0029] Specifically, the outer ring wall of the bearing 20 of the present application is mounted on the cavity top 11 of the detection cavity 10 in a tight fit manner, and the guide ring 30 is mounted on the inner ring wall of the bearing 20 in a tight fit manner. When the cuvette mounting mechanism is working, the structural characteristics of the bearing 20 can be utilized, so that the guide ring 30 can drive the cuvette mounted on the guide ring 30 to rotate on the detection cavity 10 to meet the use requirements of the spectrophotometer.

[0030] The guide ring 30 of the present application partially extends out of the cavity top 11 of the detection cavity 10, and the barrel rack 40 is detachably mounted on the portion of the guide ring 30 extending out of the cavity top 11; the adjustment ring 60 is threadedly mounted on the barrel rack 40 at one end away from the guide ring 30, and the adjustment ring 60 is arranged opposite to the guide ring 30; and the adjustment ring 60 can cooperate with the guide ring 30 and clamp the cotton ring 50; wherein, the inner diameter of the cotton ring 50 is smaller than the inner diameter of the guide ring 30. It should be noted that the inner diameter of the cotton ring 50 of the present application is smaller than the inner diameter of the guide ring 30, so that the cotton ring 50 can partially extend into the space on the guide ring 30 for accommodating the cuvette, so that when the cuvette is placed in the guide ring 30, it needs to pass through the cotton ring 50 and rub against the cotton ring 50, so that the cotton ring 50 can wipe the outer wall of the cuvette, thereby ensuring the smoothness of the outer surface of the cuvette.

[0031] It can be understood that the adjustment ring 60 of the present application can move toward the guide ring 30, and can cooperate with the guide ring 30 and open the cotton ring 50. In this way, the stability of the assembly position of the cotton ring 50 between the guide ring 30 and the adjustment ring 60 can be ensured to prevent the cotton ring 50 from contacting the outer wall of the cuvette and causing relative displacement, that is, when the cuvette installation mechanism is working, the cotton ring 50 can wipe the cuvette placed in the guide ring 30.

[0032] The adjustment ring 60 of the present application can cooperate with the guide ring 30 and stretch the cotton ring 50 to limit the cotton ring 50 between the guide ring 30 and the adjustment ring 60. In other words, when the cuvette installation mechanism of the present application is working, the inner diameter of the cotton ring 50 can be adjusted by using the cooperation between the adjustment ring 60 and the guide ring 30, and combined with the structure of the cotton ring 50 itself, the stability of the installation of the cotton ring 50 between the guide ring 30 and the adjustment ring 60 can be improved.

[0033] like Figure 2 As shown, a first inclined surface 31 is provided on one end of the guide ring 30 of the present application facing the adjustment ring 60, and a second inclined surface 61 matching the first inclined surface 31 is provided on one end of the adjustment ring 60 facing the guide ring 30. The guide ring 30 and the adjustment ring 60 can cooperate and clamp the cotton ring 50 through the first inclined surface 31 and the second inclined surface 61, so as to specifically realize the clamping effect of the cotton ring 50 when the guide ring 30 and the adjustment ring 60 cooperate, and have a simplified structure, which is convenient for adjusting the inner diameter of the cotton ring 50.

[0034] The cotton loop 50 of the present application includes an elastic loop (not shown) and a non-woven fabric (not shown), and the non-woven fabric is wrapped in the elastic loop to specifically implement the structural setting of the cotton loop 50, so as to meet the requirements of installing the cotton loop 50 between the guide ring 30 and the adjustment ring 60, and to achieve the use requirements of wiping the outer wall of the cuvette passing through the cotton loop 50.

[0035] The barrel rack 40 and the guide ring 30 of the present application are connected and fixed by means of threads, and the barrel rack 40 can be placed flat on the cavity top 11 of the detection cavity 10, so as to specifically realize the assembly connection between the barrel rack 40 and the guide ring 30, and facilitate the installation of the barrel rack 40 on the guide ring 30, while also improving the stability of the barrel rack 40 placed on the cavity top 11 of the detection cavity 10. It should be noted that the assembly method between the barrel rack 40 and the guide ring 30 is not limited to that shown in the figure, and for those skilled in the art, the barrel rack 40 and the guide ring 30 can also be assembled and connected by means of buckles and the like.

[0036] The adjustment ring 60 of the present application partially extends out of the barrel rack 40 and is formed with a screwing portion 62. The screwing portion 62 can drive the adjustment ring 60 to rotate relative to the barrel rack 40 to adjust the installation position of the adjustment ring 60 on the barrel rack 40, so that when the cuvette installation mechanism is working, the screwing portion 62 can be used as the action portion to achieve the position adjustment of the adjustment ring 60 on the barrel rack 40, which can facilitate the position adjustment of the adjustment ring 60 on the barrel rack 40, so as to facilitate the adjustment of the inner diameter of the cotton ring 50.

[0037] like Figure 3As shown, a working hole 41 is opened on the peripheral wall of the barrel rack 40 of the present application, and the cotton ring 50 can pass through the working hole 41 and be placed between the guide ring 30 and the adjustment ring 60, so that when the cuvette mounting mechanism is working, the cotton ring 50 can be replaced through the working hole 41 on the barrel rack 40, that is, the cotton ring 50 can be replaced in the cuvette mounting mechanism to meet the use requirements of the cuvette mounting mechanism in a spectrophotometer.

[0038] It can be understood that the detection cavity 10 of the present application is also provided with a through hole 12, so that in the experimental equipment for applying the cuvette installation mechanism, the light beam generated by the spectrophotometer can pass through the through hole 12 and directly irradiate the cuvette, so as to meet the use requirements of the cuvette placed in the guide ring 30 for phosphorus content detection. It should be noted that the through hole 12 on the detection cavity 10 is specifically arranged at a position below the guide ring 30, so that the light beam generated by the spectrophotometer when working can pass through the through hole 12 and directly irradiate the cuvette, that is, to meet the use requirements of the spectrophotometer.

[0039] The cuvette installation mechanism of the present application also includes a cotton ring adjustment plate 70, which can drive the cotton ring 50 to separate from the guide ring 30 in a direction away from the guide ring 30 to adjust the position of the cotton ring 50 relative to the guide ring 30. When the cuvette installation mechanism of the present application is working, the cotton ring adjustment plate 70 can be used to assist in the process of replacing the cotton ring 50, and specifically, the cotton ring adjustment plate 70 is used to align the position of the cotton ring 50, so as to ensure that the position where the cotton ring 50 can be placed on the guide ring 30 does not shift. It should be noted that when the cotton ring 50 is not placed correctly on the guide ring 30 and is tilted, the second inclined surface 61 on the adjustment ring 60 will directly act on the cotton ring 50 during the process of squeezing the cotton ring 50, causing damage to the cotton ring.

[0040] Specifically, the cotton loop adjustment plate 70 of the present application is mounted on the guide ring 30 and can move axially relative to the guide ring 30; wherein, the cotton loop adjustment plate 70 is provided with a concave arc surface 71 at the outer position of the guide ring 30, and the cotton loop adjustment plate 70 can drive the cotton loop 50 to separate from the guide ring 30 through the concave arc surface 71 to adjust the position of the cotton loop 50. When the cotton loop adjustment plate 70 adjusts the position of the cotton loop 50, the cooperation between the cotton loop adjustment plate 70 and the guide ring 30 can be used as a guide, so that the cotton loop adjustment plate 70 can move vertically upward and contact and lift the cotton loop 50 with the concave arc surface 71, and when the cotton loop 50 separates from the guide ring 30, the cotton loop 50 will move on the concave arc surface 71 under the action of its own gravity, thereby achieving the function of adjusting the position of the cotton loop 50, and then the cotton loop adjustment plate 70 is driven in the reverse direction, so that the cotton loop 50 can fall to the position on the guide ring 30 and be corrected.

[0041] Among them, the cotton loop adjustment plate 70 of the present application has a handle 72, and the handle 72 extends outward relative to the working hole 41 of the barrel rack 40, so that when people use the cotton loop adjustment plate 70, the human hand can act on the handle 72 and drive the cotton loop adjustment plate 70, so as to facilitate the driving of the cotton loop adjustment plate 70.

[0042] In summary, the cuvette mounting mechanism of the present invention, through a reasonable structural arrangement, ensures that when the cuvette is installed on the cuvette mounting mechanism, the cuvette needs to pass through the cotton ring 50 and be placed in the guide ring 30. During this process, the cotton ring 50 can wipe the outer wall of the cuvette to ensure the smoothness of the outer surface of the cuvette, which can improve the accuracy of the data obtained when the experimental equipment using the cuvette mounting mechanism is working; at the same time, the inner diameter of the cotton ring 50 can be adaptively adjusted by adjusting the position of the adjustment ring 60 on the barrel rack 40, which not only facilitates the adjustment of the inner diameter of the cotton ring 50 to meet the use requirements of wiping the outer wall of the cuvette with the cotton ring 50, but also ensures the stability of the cotton ring 50 installed between the guide ring 30 and the adjustment ring 60.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
