Description

A quantitative module light-blocking device Technical Field

[0001] This utility model relates to the field of quantitative module technology, and in particular to a quantitative module light-shielding device. Background Technology

[0002] A quantitative tube is a laboratory tool or industrial device used for the precise measurement and dispensing of liquids. It is widely used in fields such as chemistry, biology, medicine, and environmental monitoring, primarily for quantitative analysis, sample preparation, and experimental procedures. When analyzing certain liquids within a quantitative tube, light protection is required; therefore, the tube must be placed in a relatively dark, light-shielding device. When injecting reagents into the tube using pipettes or other liquid handling mechanisms, the light-shielding device needs to be opened. Therefore, the door of the light-shielding device may be frequently opened.

[0003] Existing light-blocking devices generally use motors to drive the door panel to open and close. However, the use of motors not only increases the cost of the light-blocking device, but also makes the structure for opening and closing the door panel complex and bulky, resulting in the light-blocking device occupying a large space and making it unsuitable for use in small spaces. Summary of the Invention

[0004] The purpose of this invention is to provide a quantitative module light-blocking device, which has a compact structure and is suitable for use in scenarios with limited space.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A quantitative module light-shielding device includes: an installation mechanism having a receiving cavity for receiving a quantitative tube; a light-shielding mechanism including a light-shielding cover and a light-shielding plate, the light-shielding cover being disposed on the installation mechanism and covering the opening of the receiving cavity, the light-shielding cover having an opening and closing port facing the opening of the receiving cavity, and the light-shielding plate being rotatably mounted at the opening and closing port; and a reset mechanism installed between the light-shielding plate and the light-shielding cover, the light-shielding plate being able to rotate to open the opening and closing port under the action of an external force (pressing or pulling), and being able to rotate in the opposite direction to close the opening and closing port under the action of the reset mechanism after the external force is released.

[0007] Preferably, the reset mechanism includes a first magnetic attractor and a second magnetic attractor, the first magnetic attractor being disposed on the light-shielding plate and the second magnetic attractor being disposed on the light-shielding cover.

[0008] Preferably, the first magnetic attractor and / or the second magnetic attractor are both electromagnetic components.

[0009] Preferably, the reset mechanism includes an elastic element. When the light-shielding plate is opened under the action of an external force, the elastic element can accumulate elastic potential energy. After the external force is released, the elastic element can release the elastic potential energy, so that the light-shielding plate can automatically reset.

[0010] Preferably, the elastic element is a compression spring, one end of which is fixed to the bottom surface of the light-shielding plate, and the other end of which is connected to the light-shielding cover located below the light-shielding plate; or, the elastic element is a tension spring, one end of which is fixed to the top surface of the light-shielding plate, and the other end of which is connected to the light-shielding cover located above the light-shielding plate; or, the elastic element is a torsion spring, which is located at the rotatable connection between the light-shielding plate and the light-shielding cover.

[0011] Preferably, one end of the light-shielding plate is rotatably connected to one side of the light-shielding cover, and the other side of the light-shielding cover is provided with a limiting structure, which is used to limit the light-shielding plate to the closed position.

[0012] Preferably, the quantitative module light-shielding device further includes a quantitative module, which is mounted on the mounting mechanism. The mounting mechanism has a light hole that communicates with the accommodating cavity, and the head of the quantitative module can emit detection light into the accommodating cavity through the light hole.

[0013] Preferably, the quantitative module light-shielding device further includes a quantitative circuit adapter plate, which is installed on the quantitative module and electrically connected to the quantitative module.

[0014] Preferably, the quantitative module is detachably mounted on the side of the mounting mechanism, and the quantitative circuit adapter board is detachably mounted on the side of the quantitative module opposite to the mounting mechanism.

[0015] Preferably, the light-shielding device for the quantitative module further includes a protective structure, which covers the quantitative circuit adapter board and the quantitative module.

[0016] The beneficial effects of this utility model are:

[0017] The quantitative module light-shielding device provided by this utility model includes an installation mechanism, a light-shielding mechanism, and a reset mechanism. The installation mechanism forms a receiving cavity for receiving a quantitative tube. The light-shielding mechanism includes a light-shielding cover and a light-shielding plate. The light-shielding cover is mounted on the installation mechanism and covers the opening of the receiving cavity. The light-shielding cover has an opening and closing port that faces the opening of the receiving cavity. The light-shielding plate is rotatably mounted at the opening and closing port. The reset mechanism is installed between the light-shielding plate and the light-shielding cover. The light-shielding plate can rotate to open the opening and closing port under the downward pressure or downward pull of an external force, and can rotate in the opposite direction to close the opening and closing port under the action of the reset mechanism after the external force is released. This quantitative module light-shielding device automatically opens and closes the opening and closing port under the downward pressure of a pipetting mechanism or a quantitative tube, or under the downward pull of a component located below the light-shielding plate, by means of a reset mechanism, so that the light-shielding plate can automatically rotate in the opposite direction to close the opening and closing port after the external force is released. Because the reset mechanism is installed between the light shield and the light shield, and the component that provides the pull-down action is also located below the light shield, the pipetting mechanism or metering tube that provides the pressing action is not actually part of the metering module light shield. Therefore, the metering module light shield has a compact structure, occupies a small volume, and can be used in small space scenarios. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] As shown in Figures 1 to 4, this utility model provides a quantitative module light-shielding device, which includes an installation mechanism 100, a light-shielding mechanism 200, and a reset mechanism 300. The installation mechanism 100 is used to install the light-shielding mechanism 200, and the installation mechanism 100 forms a receiving cavity 101 for receiving a quantitative tube 10. Optionally, the bottom of the receiving cavity 101 is a conical hole to facilitate positioning of the quantitative tube 10 with a conical bottom. The light-shielding mechanism 200 is used to block the opening of the receiving cavity 101, thereby preventing light from shining on the metering tube 10 from the top. Specifically, the light-shielding mechanism 200 includes a light-shielding cover 210 and a light-shielding plate 220. The light-shielding cover 210 is mounted on the mounting mechanism 100 and covers the opening of the receiving cavity 101. The light-shielding cover 210 has an opening and closing port 211 that faces the opening of the receiving cavity 101. The light-shielding plate 220 is rotatably mounted at the opening and closing port 211. Pipettes, pipettes, and other pipetting mechanisms, as well as the metering tube 10, all enter and exit the receiving cavity 101 through the open opening and closing port 211. The reset mechanism 300 is installed between the light-shielding plate 220 and the light-shielding cover 210. The light-shielding plate 220 can rotate to open the opening and closing port 211 under the pressure of an external force, and can rotate in the opposite direction to close the opening and closing port 211 under the action of the reset mechanism 300 after the external force is released. It should be noted that the external force here can be the downward pressure generated by the pipetting mechanism and the metering tube 10 pressing down on the light shield 220 from top to bottom.

[0035] The quantitative module light-shielding device provided by this utility model automatically opens and closes the opening and closing port 211 of the light-shielding cover 210 by rotatably connecting the light-shielding plate 220 to the opening and closing port 211. This allows the opening and closing port to open automatically under the pressure of a pipetting mechanism or the quantitative tube 10, without requiring a power component such as a motor to provide opening power. Furthermore, the quantitative module light-shielding device of this utility model includes a reset mechanism 300. After the external force is released, the light-shielding plate 220 automatically rotates in the opposite direction under the drive of the reset mechanism 300, thereby closing the opening and closing port 211, thus achieving automatic light-shielding. This process also does not require a power component such as a motor to provide opening power. In short, whether the light-shielding plate 220 opens or closes the opening and closing port 211, the device automatically closes the light-shielding cover. Since the reset mechanism 230 is installed between the light shield 220 and the light shield 210, and the component that provides the pull-down action is also located below the light shield 220, the pipetting mechanism or metering tube that provides the pressing action does not belong to the metering module light shielding device at all. Therefore, the metering module light shielding device has a compact structure, occupies a small volume, and can be used in small space scenarios.

[0036] Furthermore, the reset mechanism 300 is a non-powered component, which means that the quantitative module light-shielding device does not require the drive of power components such as motors. This reduces the manufacturing and usage costs of the quantitative module light-shielding device, further reduces the overall structural space, and makes it more compact and suitable for use in small spaces.

[0037] Referring again to Figure 1, a first mounting portion 110 is formed at the bottom of the mounting mechanism 100. A first mounting hole 111 is formed on the first mounting portion 110. The first connector passes through the first mounting hole 111 and is fixed to the external support structure (not shown in the figure), thereby realizing the assembly of the entire quantitative module light-shielding device with the external support structure. This arrangement helps to improve the stability of the quantitative module light-shielding device. Optionally, the mounting mechanism 100 is generally "I"-shaped, and two first mounting portions 110 are formed at the bottom of the mounting mechanism 100. The "I"-shaped mounting mechanism 100 has a recessed structure 120 above each of the first mounting portions 110. The recessed structure 120 facilitates the installation of the first connector in the first mounting hole 111.

[0038] Referring again to Figures 1 and 2, the light shield 210 is cubic in shape, with a rectangular opening 211 formed at the top. The light shield 220 is a rectangular plate, installed below the opening 211. Of course, in other embodiments, the shapes of the light shield 210, the opening 211, and the light shield 220 can be adjusted to other shapes as needed.

[0039] The light shield 210 has a cavity 212 for accommodating the light shield 220. One end of the light shield 220 is a rotating end, which is rotatably connected to the light shield 210. The other end of the light shield 220 is an opening and closing end. Under the action of external force, the opening and closing end of the light shield 220 rotates around its rotating end, thereby realizing opening and closing.

[0040] To prevent the light-shielding plate 220 from rotating too much in the opposite direction and disengaging from the opening / closing port 211, one end of the light-shielding plate 220 is rotatably connected to one side of the light-shielding cover 210, and the other side of the light-shielding cover 210 is provided with a limiting structure to limit the light-shielding plate 220 to the closed position. Optionally, the limiting structure is a limiting surface. In one embodiment, the wall thickness of the wall panel of the light-shielding cover 210 is uneven in the height direction, and the thickness of the portion of the wall panel forming the receiving cavity 212 is less than the thickness of the portion of the wall panel forming the opening / closing port 211, thereby forming a limiting surface at the location where the wall thickness changes. In addition to a limiting surface, a limiting protrusion or other structure may also be used. Furthermore, a rotating groove 213 is formed inside the light-shielding cover 210, and the rotating end of the light-shielding plate 220 is rotatably connected to the rotating groove 213.

[0041] Optionally, both the mounting mechanism 100 and the light-shielding mechanism 200 are treated with black oxidation to further reduce the influence of external light, so that the light-shielding plate 220 can block all external light from shining on the quantitative tube 10 when it is in a normal closed state, so that the quantitative tube 10 is basically in a dark environment without light.

[0042] Regarding the specific structure of the reset mechanism 300, in some embodiments, the reset mechanism 300 includes a first magnetic 310 and a second magnetic 320. The first magnetic 310 is disposed on the light-shielding plate 220, and the second magnetic 320 is disposed on the light-shielding cover 210. Optionally, the first magnetic 310 and the second magnetic 320 can be magnets with the same polarity, thereby forming a repulsive force. The second magnetic 320 disposed on the light-shielding cover 210 is located below the first magnetic 310. After the pipette or pipette is aligned with the quantitative tube 10, it moves downward and applies force to push open the light-shielding plate 220, thereby adding the reagent it carries into the quantitative tube 10. After the reagent is added into the quantitative tube 10, the pipette or pipette is removed from the light-shielding cover 210. During this process, the magnetic force between the first magnetic 310 and the second magnetic 320 causes the light-shielding plate 220 to automatically close and block light, achieving the working environment required for the quantitative module 600. Of course, in other embodiments, the positions of the first magnetic member 310 and the second magnetic member 320 can also be changed. For example, the second magnetic member 320 disposed on the light shield 210 can be disposed above the first magnetic member 310. In this case, the first magnetic member 310 and the second magnetic member 320 can be magnets with opposite polarities, thereby generating an attraction.

[0043] In some parallel embodiments, both the first magnetic chuck 310 and the second magnetic chuck 320 are electromagnetic components. By energizing the first magnetic chuck 310 and the second magnetic chuck 320, they can attract or repel each other. By changing the direction of the current, the polarity of the first magnetic chuck 310 and the second magnetic chuck 320 can be changed; if the polarities are the same, they will repel each other, and if the polarities are opposite, they will attract each other. It should be noted that if the first magnetic chuck 310 and the second magnetic chuck 320 are in a state of opposite polarities, the mutual attraction between them can provide a downward pulling force for opening the light-shielding plate 220; if the first magnetic chuck 310 and the second magnetic chuck 320 are in a state of the same polarity, the mutual repulsion between them can provide an upward pushing force for closing the light-shielding plate 220. It should be noted that, compared to using a pipette or quantitative tube to open the light shield 220, which may leave reagent residue and easily cause contamination, the attraction between the first magnetic element 310 and the second magnetic element 320 provides a downward pulling force for opening the light shield 220, which helps maintain the cleanliness of the light shield 220. Of course, in other embodiments, one of the first magnetic element 310 and the second magnetic element 320 can be an electromagnetic element, and the other can be a metal element that can be attracted by the electromagnetic element. Whether the metal element is attracted is determined by controlling whether the first magnetic element 310 or the second magnetic element 320 is energized.

[0044] Optionally, a mounting protrusion 214 is formed inside the light shield 210, located directly below the rotating groove 213. A first mounting groove is formed inside the rotating end of the light shield 220, and the first magnetic member 310 is placed in the first mounting groove. A second mounting groove is provided on the mounting protrusion 214, and the second magnetic member 320 is placed in the second mounting groove. The first mounting groove can improve the installation stability of the first magnetic member 310, and the second mounting groove can improve the installation stability of the second magnetic member 320.

[0045] Regarding the specific structure of the reset mechanism 300, in some parallel embodiments, the reset mechanism 300 includes an elastic element. When the light shield 220 is opened under the action of an external force, the elastic element can accumulate elastic potential energy. After the external force is released, the elastic element can release the elastic potential energy so that the light shield 220 automatically resets.

[0046] In one specific embodiment, the elastic element is a compression spring, with one end fixed to the bottom surface of the light-shielding plate 220 and the other end connected to the light-shielding cover 210 located below the light-shielding plate 220. In another specific embodiment, the elastic element is a tension spring, with one end fixed to the top surface of the light-shielding plate 220 and the other end connected to the light-shielding cover 210 located above the light-shielding plate 220. In yet another specific embodiment, the elastic element is a torsion spring, located at the rotatable connection between the light-shielding plate 220 and the light-shielding cover 210. Of course, the elastic element can also be other elastic structures, and is not limited to compression springs, tension springs, and torsion springs.

[0047] Referring again to Figure 2, the quantitative module light-shielding device further includes a quantitative module 600, which is mounted on the mounting mechanism 100. The mounting mechanism 100 has a light hole 102 communicating with the accommodating cavity 101. The head of the quantitative module 600 can emit detection light into the accommodating cavity 101 through the light hole 102. For example, the detection light can be used to detect the fluorescence signal of the reagent, thereby analyzing the concentration. Optionally, the extending direction of the light hole 102 is perpendicular to the extending direction of the accommodating cavity 101, so that light shines on the quantitative tube 10 from the side.

[0048] In some embodiments, continuing to refer to FIG1, a second mounting portion 130 is provided on the mounting mechanism 100, and a second mounting hole 131 is provided on the second mounting portion 130. The second connector passes through the second mounting hole 131 and is fixed on the metering module 600, thereby fixing the metering module 600 to the mounting mechanism 100. Optionally, a plurality of spaced-apart second mounting holes 131 are provided on the second mounting portion 130.

[0049] Referring again to Figures 1, 2, and 4, the quantitative module light-shielding device further includes a quantitative circuit adapter plate 400, which is mounted on and electrically connected to the quantitative module 600. Optionally, the quantitative module 600 is detachably mounted on the side of the mounting mechanism 100, and the quantitative circuit adapter plate 400 is detachably mounted on the side of the quantitative module 600 opposite to the mounting mechanism 100. This arrangement makes the layout of the components of the quantitative module light-shielding device reasonable and helps to improve the structural compactness.

[0050] In some embodiments, a plurality of third mounting holes are provided on the quantitative circuit adapter plate 400, and a plurality of third connectors pass through the corresponding third mounting holes, thereby fixing the top of the quantitative circuit adapter plate 400 to the quantitative module 600 and fixing the bottom of the quantitative circuit adapter plate 400 to the mounting mechanism 100, thereby realizing the fixation of the quantitative circuit adapter plate 400 with the quantitative module 600 and the mounting mechanism 100.

[0051] Referring again to Figure 1, the light-shielding device for the quantitative module further includes a protective structure 500, which covers the quantitative circuit adapter plate 400 and the quantitative module 600. The protective structure 500 protects the quantitative circuit adapter plate 400 and the quantitative module 600, thereby preventing dust or other foreign objects from entering them. Optionally, the protective structure 500 is a protective cover formed by splicing together protective plates.

[0052] In summary, the quantitative module light-shielding device provided by this utility model only requires a small space on the equipment table to realize the analysis function of the quantitative module 600. It does not require other power structure parts to open and close the light-shielding plate 220, which not only makes sample addition faster, but also further reduces the overall structure. Its volume is 1 / 3 of the volume of the existing quantitative module light-shielding device, and it is easy to install and has a simple structure.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
