[0036] It should also be noted that, in the embodiments of the present application, the same figure mark represents the same component or the same part. For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0037] According to one aspect of the present application, an embodiment of the present application provides a capping module, such as Figures 1-4 As shown, the cover module includes a mounting bracket 100 and a pressing assembly 200. The mounting bracket 100 has a first position and a second position. Below the second position is a carrier 10 for holding the test consumables 20. The pressing assembly 200 includes a moving member 210 and a pressing plate 230 movably connected to the moving member 210 through a connecting member 220. The moving member 210 is slidably arranged on the mounting bracket 100 and can be moved on the mounting bracket 100 at the first position ( Figure 1 and Figure 2 The position of the moving member 210) and the second position ( Figure 3 and Figure 4 A guide structure is provided between the pressure plate 230 and the mounting bracket 100. When the movable member 210 moves from the first position to the second position, the pressure plate 230 is driven to gradually move away from the movable member 210 and downward under the action of the guide structure to press the detection consumables 20 on the carrier 10.

[0038] In the embodiment of the present application, the pressure cover module includes a mounting bracket 100 and a pressing assembly 200, which has a simple structure. When in use, it is only necessary to set the carrier 10 containing the detection consumables 20 on the mounting bracket 100 and below the second position, which is convenient to arrange. During the movement of the movable member 210 between the first position and the second position, the pressure plate 230 is driven to move by the linkage 220. When the movable member 210 is in the first position, the pressure plate 230 is located below the first position, and the top of the carrier 10 is in an open state, which does not affect the staff's operation of taking and placing the detection consumables 20 on the carrier 10; after the detection consumables 20 are placed on the carrier 10, the movable member 210 moves from the first position to the second position, driving the pressure plate 230 to gradually move away from the movable member 210 and move downward under the action of the guide structure to press the detection consumables 20 on the carrier 10.

[0039] In one embodiment, if Figure 3-Figure 4 and Figure 6 As shown, the moving member 210 includes a moving plate, and the pressing plate 230 is movably connected to the lower end of the moving plate through the connecting member 220 and remains parallel to the moving plate. When the moving plate is in the second position, the carrier 10 is located in the vertical projection plane of the moving plate.

[0040] With the above arrangement, when the movable plate is in the second position, the upper portion of the carrier 10 is covered by the movable plate, and the movable plate acts as a protective cover to prevent foreign matter from falling onto the carrier 10 .

[0041] In one embodiment, if Figure 2 、 Figure 4 and Figure 6 As shown, the lower end of the moving member 210 and the upper surface of the pressing plate 230 are movably connected via two linking members 220 , and a parallelogram mechanism is formed between the moving member 210 , the pressing plate 230 and the two linking members 220 .

[0042] Specifically, the linkage 220 adopts a linkage plate, the two linkage plates are parallel to each other, the upper ends of the two linkage plates are rotatably connected to the lower end of the moving member 210, and the lower ends of the two linkage plates are rotatably connected to the upper surface of the pressure plate 230.

[0043] In some embodiments, as Figures 1-4 As shown, the mounting bracket 100 includes two mounting plates 110 spaced apart, the first position and the second position are located between the two mounting plates 110 and are arranged side by side along the length direction of the mounting plates 110, the moving member 210 is slidably arranged between the two mounting plates 110 along the length direction of the mounting plates 110, and the guide structure is arranged between the pressure plate 230 and the inner side of the mounting plate 110.

[0044] The mounting bracket 100 is configured as described above, resulting in a simple structure. Furthermore, the mounting bracket 100 may further include a first baffle 120 and a second baffle 130 spaced apart below the second position. The first baffle 120, the second baffle 130, and the two mounting plates 110 define a region for mounting the carrier 10. The first baffle 120, the second baffle 130, and the two baffles further provide shielding and protection for the testing consumables 20 located on the carrier 10.

[0045] It is understandable that the mounting bracket 100 serves as a carrier for mounting the pressing assembly 200 and for external installation, and it may also have other structural forms, which are not limited here.

[0046] In a specific embodiment, Figure 2 、 Figure 4 and Figure 5-Figure 6 As shown, guide rails 111 extending along the length direction of the mounting plates 110 are provided on the opposite inner sides of the two mounting plates 110 , and opposite ends of the moving member 210 are slidably connected to the two guide rails 111 through sliders 211 .

[0047] The sliding connection between the mounting plate 110 and the moving member 210 is achieved by a linear guide rail formed by the slider 211 and the guide rail 111, which is convenient for installation and the sliding connection is simple and reliable.

[0048] Of course, it is conceivable that in order to achieve a sliding connection between the movable member 210 and the two mounting plates 110, the relative inner sides of the two mounting plates 110 may also be provided with guide grooves extending along the length direction of the mounting plates 110, and the relative ends of the movable member 210 are respectively fixed with guide blocks that are slidably connected to the guide grooves.

[0049] In a specific embodiment, Figure 2 、 Figure 4 and Figure 5-Figure 6 As shown, the guide structure includes a guide groove 112 arranged on the inner side of the mounting plate 110 and a roller 231 arranged at the end of the pressure plate 230 and slidingly arranged in the guide groove 112, the guide groove 112 includes a straight section 1121 extending along the length direction of the mounting plate 110, a vertical section 1122 located at one end of the straight section 1121 and extending vertically downward, and an arc-shaped transition section 1123 connected between the straight section 1121 and the vertical section 1122, the end of the straight section 1121 away from the vertical section 1122 is located below the first position, and the vertical section 1122 is located below the second position.

[0050] This configuration saves the internal space of the mounting bracket 100 and is conducive to the miniaturization design of the entire gland module.

[0051] It should be noted that if Figure 2 As shown, the vertical distance between the straight section 1121 of the guide groove 112 and the guide rail 111 is smaller than the distance between the end of the linking member 220 connected to the pressure block and the end of the linking member 220 connected to the moving member.

[0052] It is understandable that the guide structure can also have other forms. For example, the guide groove 112 on the inner side of the above-mentioned mounting plate 110 can be replaced by a guide rail of similar shape, and the roller 231 at the end of the pressure plate 230 can be replaced by a sliding block slidably connected to the guide rail.

[0053] In a more specific embodiment, Figure 5-Figure 6 As shown, guide structures are provided between the opposite ends of the pressing plate 230 and the opposite inner sides of the two mounting plates 110. This arrangement improves the guidance of the pressing plate 230 and the stability of the pressing plate 230 during movement.

[0054] In some embodiments, as Figures 1-4 As shown, the capping module further includes a driving member 300 , which is disposed on the mounting bracket 100 and connected to the moving member 210 . The driving member 300 is used to drive the moving member 210 to move between the first position and the second position.

[0055] The moving member 210 is driven to move by the driving member 300, and manual operation by the staff is unnecessary, which reduces the burden on the staff and is beneficial to improving the degree of automation of the equipment.

[0056] In one implementation, the driving member 300 includes a through-type lead screw stepper motor, the lead screw of the through-type lead screw stepper motor is fixedly disposed on the mounting bracket 100 , and the motor body of the through-type lead screw stepper motor is connected to the moving member 210 via an adapter plate 310 .

[0057] It is understandable that the driving member 300 may also be a pneumatic cylinder, an electric cylinder, a linear motor, etc.

[0058] According to another aspect of the present application, an embodiment of the present application also provides a molecular detection device, including a carrier 10 for holding a detection consumable 20 and a cover module in any of the above embodiments, wherein the carrier 10 is arranged on the mounting bracket 100 and is located below the second position.

[0059] Since the molecular detection device adopts the capping module in the above embodiment, it also has the advantages and benefits brought by the above capping module, which will not be described in detail here.

[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.

[0061] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
