Description

Technical Field

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

[0002] Before operation, dynamic optical path modules require calibration to ensure functional stability and accuracy. Currently, dynamic optical path modules typically utilize different reagent strips inserted sequentially into their detection slots. The pre-set detection and control lines on the reagent strips serve as physical references for optical path calibration, enabling the calibration of the dynamic optical path module.

[0003] During the debugging of the dynamic optical path module using reagent strips, the optical testing module of the dynamic optical path module emits a laser to the detection area of ​​the reagent strip and excites a fluorescence signal. Then, by comparing the light intensity and position deviation of the detection line and the quality control line, the angle of the reflector or the position of the focusing lens in the optical path is calibrated in reverse, thereby completing the debugging of the dynamic optical path module.

[0004] However, during the aforementioned debugging process, ambient light can interfere with the emitted fluorescence signal, greatly affecting the accuracy of fluorescence signal acquisition and consequently the accuracy of dynamic optical path module debugging. Therefore, when debugging the dynamic optical path module, it is necessary to shield it from light to ensure the accuracy of the debugging.

[0005] Therefore, there is an urgent need for a device that can block light from the dynamic optical path module during the debugging process, so as to ensure the accuracy of the debugging effect and results. Utility Model Content

[0059] In one embodiment of this utility model, the dynamic optical path module has a detection slot. When the dynamic optical path module needs to be debugged, the operator inserts a reagent card into the detection slot on the dynamic optical path module to debug it. The above content is all prior art known to those skilled in the art and will not be elaborated further here.

[0060] Reference Figure 1-15 This utility model provides a light-shielding device for dynamic optical path module debugging, the device including at least a top (i.e., Figure 5 The shell 1 (top of the middle shell 1) is an open structure, the spring telescopic rod 3, the lifting mechanism, and the locking mechanism are as follows:

[0061] Reference Figure 5 , Figure 8 and Figure 11 The fixed end of the spring telescopic rod 3 is installed on the bottom inner wall of the housing 1, and the spring telescopic rod 3 is set parallel to the height direction of the housing 1.

[0062] In this embodiment, refer to Figure 5 and Figure 8 The shell 1 can be a cuboid structure, and the long side of the cuboid shell 1 can be oriented upwards (i.e., Figure 5 , Figure 8 and Figure 11 (above the center), at this time, the long side of the cuboid shell 1 is the height of the shell 1. Since the spring telescopic rod 3 is set parallel to the height direction of the shell 1, the spring telescopic rod 3 is set parallel to the long side of the cuboid shell 1.

[0063] In this embodiment, refer to Figure 8 The fixed end of the spring telescopic rod 3 can be installed at the center of the inner wall at the bottom of the housing 1.

[0064] In one embodiment of this utility model, reference can be made to Figure 8 and Figure 11 The specific structure of the spring telescopic rod 3 is as follows: it includes a cylindrical sleeve (i.e., the fixed end of the spring telescopic rod 3), the top of the sleeve is a cylindrical opening, and a cylindrical lifting column (i.e., the telescopic end of the spring telescopic rod 3) is slidably installed inside the sleeve. The side wall of the lifting column is slidably engaged with the inner wall of the opening at the top of the sleeve. A spring is installed inside the sleeve, and the two ends of the spring are connected to the bottom end of the inner wall of the sleeve and the bottom end of the lifting column, respectively. (Refer to...) Figure 11 The bottom side wall of the lifting column is equipped with a protrusion. When the lifting column is in the highest position, the top of the protrusion will abut against the inner wall of the top of the sleeve to limit the lifting column and prevent it from completely detaching from the sleeve.

[0065] In this embodiment, the connection between the fixed end of the spring telescopic rod 3 and the inner wall of the bottom end of the housing 1 can be a method known in the art, such as connecting the two by bolts, and is not particularly limited here.

[0066] According to one embodiment of the present invention, referring to Figure 2 and Figure 4 The lifting mechanism is limited and slidably fitted inside the housing 1, and the bottom end of the lifting mechanism abuts against the telescopic end of the spring telescopic rod 3; the lifting mechanism is used to install the dynamic optical path module.

[0067] In this embodiment, when the lifting mechanism is in a limiting sliding fit inside the housing 1, the bottom end of the lifting mechanism can abut against the telescopic end of the spring telescopic rod 3, so that the lifting mechanism can achieve an automatic lifting effect under the elastic force of the spring inside the spring telescopic rod 3.

[0068] According to one embodiment of the present invention, referring to Figure 2 , Figure 4 , Figure 12 and Figure 14 The top of the lifting mechanism is equipped with a top cover 16. The top cover 16 is configured to completely cover the opening structure at the top of the housing 1. That is, when the bottom end of the top cover 16 abuts against the top end of the housing 1, the top cover 16 can completely cover the opening structure at the top of the housing 1 to achieve a sealing effect on the interior of the housing 1, thereby preventing external ambient light from entering the interior of the housing 1.

[0069] In this embodiment, refer to Figure 1 The shape of the top cover 16 can be exactly the same as the top shape of the shell 1, and the area of ​​the top cover 16 can also be exactly the same as the top area of ​​the shell 1. In this way, the opening structure at the top of the shell 1 can be completely covered, while also improving the integrity of the device.

[0070] According to one embodiment of the present invention, referring to Figure 4 and Figure 8 The locking mechanism is installed on the housing 1. The locking mechanism is configured to detachably connect the top cover 16 to the top of the housing 1. That is, when the bottom end of the top cover 16 abuts against the top end of the housing 1, the locking mechanism can lock the top cover 16 to the top end of the housing 1; and when it is necessary to separate the top cover 16 from the top end of the housing 1, the locking mechanism can unlock the top cover 16 from the top end of the housing 1, thereby realizing the detachable connection between the top cover 16 and the top end of the housing 1.

[0071] In one embodiment of this utility model, by configuring the housing 1, the spring telescopic rod 3, the lifting mechanism, and the locking mechanism, when the dynamic optical path module needs to be debugged, the operator can first insert a reagent card into the dynamic optical path module and install the dynamic optical path module on the lifting mechanism; then, the operator presses down on the top cover 16 (i.e., towards...). Figure 2 When the top cover 16 is pressed down from below, the top cover 16 will simultaneously drive the lifting mechanism to descend, thereby allowing the lifting mechanism and the dynamic optical path module on the lifting mechanism to gradually enter the interior of the housing 1. Finally, when the bottom end of the top cover 16 is pressed down to abut against the top end of the housing 1, the locking mechanism can lock the top cover 16 to the top end of the housing 1, thereby achieving a light-shielding effect on the interior of the housing 1, and thus achieving a light-shielding effect on the dynamic optical path module on the lifting mechanism. This avoids interference from ambient light on the excitation of fluorescence signals, and will not affect the acquisition accuracy of fluorescence signals, thereby ensuring the accuracy of the debugging effect and results of the dynamic optical path module.

[0072] According to one embodiment of the present invention, referring to Figure 2 , Figure 4 , Figure 12 and Figure 14 The lifting mechanism includes a base plate 13 that is limited and slidably fitted inside the housing 1. A dynamic optical path module mounting slot 17 is installed on the top of the base plate 13, and the dynamic optical path module is installed in the dynamic optical path module mounting slot 17.

[0073] In this embodiment, refer to Figure 2 and Figure 12 The base plate 13 can be a square structure, and the shape and area of ​​the base plate 13 can be the same as the shape and area of ​​the cross-section of the shell 1.

[0074] In this embodiment, refer to Figure 12 and Figure 13 The dynamic optical path module mounting slot 17 can be a square structure. Since most existing dynamic optical path modules are of a square structure (known in the art), a dynamic optical path module can be placed in the square dynamic optical path module mounting slot 17.

[0075] In this embodiment, the bottom end of the base plate 13 can abut against the telescopic end of the spring telescopic rod 3; that is, when the base plate 13 is located inside the housing 1, the bottom end of the base plate 13 can abut against the telescopic end of the spring telescopic rod 3, so that the base plate 13 can achieve an automatic rising effect under the elastic force of the spring inside the spring telescopic rod 3.

[0076] According to one embodiment of the present invention, referring to Figure 4 and Figure 12 A support column 15 is installed at the top of the base plate 13, and a top cover 16 is installed at the top of the support column 15.

[0077] In this embodiment, refer to Figure 4 and Figure 12 The top cover 16 and the bottom plate 13 are correspondingly and parallel to each other, that is, the center point of the top cover 16 and the center point of the bottom plate 13 are coaxially arranged (located on the same vertical plane).

[0078] In this embodiment, refer to Figure 4 The support column 15 can be an elongated cuboid structure, and there can be four supports 15, which can be installed sequentially at the top of the four corners of the base plate 13. The connection method between the support column 15 and the top cover 16 and the base plate 13 can be any method known in the art, such as using bolts to connect the support column 15 to the top cover 16 and the support column 15 to the base plate 13 respectively, and no particular limitation is made here.

[0079] In this embodiment, the length of the support column 15 is less than or equal to the length of the fixed end of the spring telescopic rod 3.

[0080] According to one embodiment of the present invention, referring to Figure 5 , Figure 8 and Figure 11 A groove 4 is provided on the inner wall of the housing 1. The length direction of the groove 4 is parallel to the length direction of the spring telescopic rod 3 (i.e., the length direction of the groove 4 is parallel to the length direction of the spring telescopic rod 3). Figure 11 The vertical direction of the slide groove 4 is parallel to the long side of the rectangular shell 1.

[0081] In this embodiment, refer to Figure 8 The slide groove 4 can be a cuboid structure, and there can be two slide grooves 4, which are symmetrically arranged on two opposite inner sidewalls of the housing 1. The length of the slide groove 4 is not specifically limited, but can be referenced... Figure 8 and Figure 11 The bottom of the slide 4 should be lower than the top of the fixed end of the spring telescopic rod 3.

[0082] According to one embodiment of the present invention, referring to Figure 12 and Figure 14 A slider 14 is installed on the side wall of the base plate 13. The slider 14 is correspondingly and compatible with the slide groove 4. The slider 14 is configured to slide and fit in the slide groove 4 so that the base plate 13 is limited to slide and fit inside the housing 1.

[0083] In this embodiment, refer to Figure 12 and Figure 14 Since the slider 14 is compatible with the groove 4 and the slider 14 can slide within the groove 4, there are two sliders 14, and the slider 14 is also a cuboid structure.

[0084] In this embodiment, the corresponding arrangement of slider 14 and slide groove 4 means that when the base plate 13 is installed inside the housing 1, slider 14 and slide groove 4 will be on the same vertical plane, that is, slider 14 can smoothly enter slide groove 4.

[0085] In this embodiment, the connection method between the slider 14 and the base plate 13 is not particularly limited, and the two can be integrally formed.

[0086] According to one embodiment of the present invention, referring to Figure 5 , Figure 6 and Figure 9 The top of the slide 4 is an open structure with an installation groove 5, and a slide limit block 6 can be detachably installed in the installation groove 5.

[0087] In this embodiment, refer to Figure 6 and Figure 9 The mounting groove 5 can be a cuboid structure, and the sliding groove limiting block 6 can be a cuboid structure with the same shape and area as the mounting groove 5. (Refer to...) Figure 6 and Figure 9 The sliding groove limit block 6 can be detachably installed in the mounting groove 5 by means of two bolts.

[0088] In one embodiment of this utility model, reference is made to Figure 2 , Figure 4 , Figure 5 and Figure 8 ,exist Figure 2 , Figure 4 , Figure 5 and Figure 8 In this embodiment, only one mounting slot 5 contains a sliding limit block 6, while the other mounting slot 5 does not contain a sliding limit block 6. Those skilled in the art should understand that this description is merely to provide a clearer understanding of the specific structure and connection method of the mounting slots 5 and the sliding limit block 6 in this embodiment, and not to represent the actual operation of the device. Those skilled in the art should also understand that in actual operation, all mounting slots 5 (two in this embodiment) require the installation of sliding limit blocks 6 to ensure the normal operation of the device.

[0089] According to one embodiment of the present invention, referring to Figure 9 When the sliding groove limiting block 6 is installed in the mounting groove 5, the top of the sliding groove limiting block 6 is set to be flush with the top of the housing 1.

[0090] In this embodiment, the top of the sliding groove limiting block 6 is set to be flush with the top of the housing 1, so the sliding groove limiting block 6 will not protrude or be recessed into the top of the housing 1. That is, when the top cover 16 is fastened to the top of the housing 1 (that is, when the bottom end of the top cover 16 abuts against the top of the housing 1), there will be no light leakage at the top of the housing 1, thus ensuring the light-proofness of the interior of the housing 1.

[0091] According to one embodiment of the present invention, referring to Figure 5 , Figure 7 and Figure 11 The locking mechanism includes a locking rod 10 that is slidably fitted on the top side wall of the housing 1, with the two ends of the locking rod 10 located inside the housing 1 and outside the housing 1, respectively.

[0092] In this embodiment, refer to Figure 7 The locking rod 10 can be a cylindrical structure.

[0093] In this embodiment, refer to Figure 7 The locking rod 10 can pass through the top side wall of the housing 1 and slide in cooperation with the housing 1, thereby achieving a limiting sliding cooperation between the locking rod 10 and the top side wall of the housing 1.

[0094] According to one embodiment of the present invention, referring to Figure 7 A locking limit block 12 is installed at one end of the locking rod 10 located outside the housing 1. A tension spring 11 is sleeved on the locking rod 10, and the two ends of the tension spring 11 are fixedly connected to the locking limit block 12 and the outer wall of the housing 1, respectively.

[0095] In this embodiment, refer to Figure 7 The locking limit block 12 can be a flat cylindrical structure, and the locking limit block 12 can be coaxially arranged with the locking rod 10. The cross-sectional area of ​​the locking limit block 12 can be larger than the cross-sectional area of ​​the locking rod 10.

[0096] In this embodiment, the fixed connection method between the two ends of the tension spring 11 and the locking limit block 12 and the outer wall of the housing 1 is not particularly limited. It can be that the two ends of the tension spring 11 are fixedly connected to the locking limit block 12 and the outer wall of the housing 1 by welding, which is known in the art.

[0097] According to one embodiment of the present invention, referring to Figure 14 and Figure 15 A locking block 20 is installed at the bottom of the top cover 16. The locking block 20 has a locking hole 21. The locking hole 21 is adapted to one end of the locking rod 10 located inside the housing 1. That is, the locking hole 21 is also a cylindrical structure.

[0098] In this embodiment, refer to Figure 14The locking block 20 can be a cuboid structure. And when the base plate 13 is located inside the housing 1, the outer wall of the locking block 20 can slide against the inner wall of the housing 1.

[0099] In one embodiment of this utility model, when the bottom end of the top cover 16 abuts against the top end of the housing 1, the locking rod 10 is configured to be inserted into the locking hole 21 to detachably connect the top cover 16 to the top end of the housing 1. When it is necessary to separate the top cover 16 from the top end of the housing 1, the locking rod 10 is pulled outward to disengage it from the locking hole 21. At this time, the bottom plate 13 will automatically rise under the action of the spring telescopic rod 3, thereby realizing the separation of the top cover 16 from the top end of the housing 1.

[0100] Furthermore, referring to Figure 14 A limiting groove 19 is provided at the bottom end of the base plate 13. The limiting groove 19 is correspondingly provided with the telescopic end of the spring telescopic rod 3, and the limiting groove 19 is adapted to the telescopic end of the spring telescopic rod 3. That is, the shape and cross-sectional area of ​​the limiting groove 19 are the same as the shape and cross-sectional area of ​​the telescopic end of the spring telescopic rod 3.

[0101] In one embodiment of this utility model, by setting the limiting groove 19, the telescopic end of the spring telescopic rod 3 can be engaged inside the limiting groove 19, thereby improving the stability of the connection between the telescopic end of the spring telescopic rod 3 and the base plate 13.

When the bottom end of the top cover 16 abuts against the top end of the housing 1 (that is, when the top cover 16 is fastened to the top end of the housing 1), the first card insertion hole 7 is configured to correspond to and communicate with the second card insertion hole 18.

[0105] In this embodiment, refer to Figure 3 The first card slot 7 can be set as a square structure with the same area as the second card slot 18.

[0106] Furthermore, referring to Figure 2 and Figure 3 The outer wall of the housing 1 is provided with a large card insertion groove 8, which is correspondingly arranged with and connected to the first card insertion hole 7. A door 9 is hinged (the hinge method is known in the art) on the side wall of the large card insertion groove 8, and the door 9 is configured to completely cover the slot of the large card insertion groove 8.

[0107] In this embodiment, refer to Figure 3 The card slot 8 can be a cuboid structure.

[0108] In this embodiment, refer to Figure 3 The door 9 can be a cuboid structure, and preferably has the same area as the card insertion recess 8.

[0109] In this embodiment, refer to Figure 3 The end of the door 9 furthest from the housing 1 has a beveled structure. Since the door 9 is hinged to the side wall of the large card slot 8, the beveled structure allows the door 9 to be easily fastened to the large card slot 8.

[0110] In one embodiment of this utility model, by setting up the card insertion groove 8, the first card insertion hole 7 and the second card insertion hole 18, when the reagent card strip of the dynamic optical path module needs to be replaced, the reagent card strip can be replaced without removing the dynamic optical path module from the housing 1, which greatly improves the efficiency of dynamic optical path module debugging.

[0111] For example, in this embodiment, when it is necessary to replace the reagent card strip on the dynamic optical path module inside the housing 1, firstly, the door 9 is opened, and the operator can take out the reagent card strip to be replaced through the first card insertion hole 7 and the second card insertion hole 18. Then, the operator can insert the new reagent card strip into the dynamic optical path module through the first card insertion hole 7 and the second card insertion hole 18, thereby replacing the reagent card strip. Finally, the door 9 is closed again to completely complete the reagent card strip replacement. Although the first card insertion hole 7 does not damage the light-shielding properties inside the housing 1, the door 9 can be used to close the first card insertion hole 7, thereby providing light-shielding treatment for the first card insertion hole 7, further ensuring the light-shielding properties inside the housing 1, and ensuring the accuracy of the dynamic optical path module debugging effect and results.

[0112] According to one embodiment of the present invention, referring to Figure 7The locking rod 10 has a beveled end inside the housing 1, and the beveled end of the locking rod 10 is set to face the top of the housing 1 (i.e., towards the top). Figure 7 The top of the housing 1, in other words, the inclined structure of the locking rod 10 faces the opening structure at the top of the housing 1.

[0113] In one embodiment of this utility model, by setting the inclined structure, when the base plate 13 is installed inside the housing 1 or when the top cover 16 needs to be installed on the top of the housing 1, the worker does not need to manually pull the locking rod 10 outward, and the locking rod 10 can be moved outward automatically, which improves convenience and work efficiency.

[0114] According to one embodiment of the present invention, referring to Figure 10 A support plate 2 is installed on the bottom outer wall of the casing 1. (Refer to...) Figure 1 A reinforcing rib is installed between the shell 1 and the support plate 2.

[0115] In this embodiment, the support plate 2 can be a flat cuboid structure, and the support plate 2 can be connected to the housing 1 by bolts.

[0116] In one embodiment of this utility model, the stability of the device can be better ensured by the provision of the support plate 2. Furthermore, the connection stability between the housing 1 and the support plate 2 can be better ensured by the provision of reinforcing ribs.

[0117] Furthermore, in this embodiment, the spring force inside the spring telescopic rod 3 is not too large, just enough to ensure that the top of the slider 14 contacts the bottom of the slide groove limiting block 6 smoothly. This can greatly reduce the vibration of the bottom plate 13 colliding with the bottom of the slide groove limiting block 6 after it has risen.

[0118] Furthermore, in this embodiment, a buffer layer (not shown in the figure) may be installed at the bottom end of the slide rail limiting block 6. The buffer layer may be made of silicone or other materials known in the art, and is not particularly limited here. By setting the buffer layer, the vibration of the bottom plate 13 colliding with the bottom end of the slide rail limiting block 6 after it has been raised can be further reduced.

[0119] The above embodiments of this utility model can be combined with each other and have corresponding technical effects.

[0120] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
