Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0034] Please see Figures 1 to 10It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show components relevant to the present invention and are not drawn according to the actual number, shape, and size of components in implementation.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives of the present invention, should still fall within the scope of the technical content disclosed in the present invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are only for clarity of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the present invention.

[0035] Please see Figure 4 and Figure 5 This embodiment provides a connecting rod 8, which can be disposed between a first connecting member and a second connecting member for connecting the first connecting member and the second connecting member. In this embodiment, one end of the connecting rod 8 is rotatably or slidably connected to the first connecting member, and the other end of the connecting rod 8 is rotatably or slidably connected to the second connecting member. An installation groove is provided on the end of the connecting rod 8 used for connecting to the second connecting member. The installation groove includes a movement groove 36 and a disengagement groove 35. The disengagement groove 35 communicates with the movement groove 36 and has a disengagement opening 39.

[0036] The second connector can be provided with corresponding protrusions such as pins, studs, and prisms. These protrusions can pass through the mounting groove and move along it. When the protrusion is in the movement groove 36, the movement groove 36 constrains the position of the protrusion to constrain the position between the connecting rod 8 and the second connector, thereby connecting the connecting rod 8 and the second connector. When the protrusion is in the disengagement groove 35, it can disengage from the mounting groove through the disengagement opening 39, disconnecting the connecting rod 8 from the second connector.

[0037] Specifically, one end of the release groove 35 is connected to one end of the motion groove 36, and the release opening 39 is opened on the end of the release groove 35 away from the motion groove 36. The release groove 35 and the motion groove 36 are arranged in different directions, so when the protrusion moves in the motion groove 36 along the direction of the motion groove 36, it will not enter the release groove 35, which can prevent the connection between the connecting rod 8 and the second connecting member from being accidentally disconnected.

[0038] This embodiment also provides a hatch structure, including a front shell 2 for mounting on a chassis, and a loading section disposed on the chassis. The chassis is used to accommodate contents such as testing reagents, and the loading section is used to load the contents and is movable within the chassis. In this embodiment, the contents are fluorescent reagent bags 5.

[0039] A door 9 is provided on the front housing 2, and a connecting rod 8 is connected to the door 9. In this embodiment, an exchange opening 10 is provided on the front housing 2, and the door 9 can open or close the exchange opening 10. The front housing 2 is rotatably or slidably connected to the chassis, the door 9 is rotatably or slidably connected to the front housing 2, one end of the connecting rod 8 is rotatably or slidably connected to the door 9, and the other end of the connecting rod 8 is rotatably or slidably connected to the loading part.

[0040] The connecting rod 8 is provided with an installation groove, and the connecting rod 8 is connected to the loading part through the installation groove. The installation groove includes a movement groove 36 and a release groove 35. The release groove 35 is connected to the movement groove 36 and has a release opening 39.

[0041] Since the connecting rods 8 are connected to both the door body 9 and the loading section, the loading section and its contents can move accordingly when the door body 9 is opened or closed, facilitating the loading and unloading of the contents. Specifically, because the connecting rods 8 are located between the door body 9 and the loading section, they can drive the loading section to move when the door body moves. During the closing process of the door body 9, the connecting rods 8 drive the loading section away from the exchange opening 10, allowing the loading section to enter the machine housing. When the door body 9 is opened, the connecting rods 8 drive the loading section closer to the exchange opening 10. Therefore, when the door body 9 is opened, the fluorescent reagent bag 5 is closer to the exchange opening 10, making it easier for operators to access and replace it.

[0042] Since the loading unit is located on the chassis, and the door 9 is connected to the front shell 2, when the connecting rod 8 connects the door 9 and the loading unit, it increases the constraint between the front shell 2 and the chassis, preventing the front shell 2 from opening. Therefore, in this embodiment, the connecting rod 8 is provided with a release groove 35, which allows the connecting rod 8 to separate from the loading unit or the door 9, thereby allowing the front shell 2 to be opened for easy inspection of the internal parts of the detection device. Specifically, as shown... Figure 1 As shown, the portion of the chassis near the operating side 1 is the front shell 2. The front shell 2 is connected to the chassis, and the exchange opening 10 and the door 9 are both located on the front shell 2. When the front shell 2 needs to be opened, the door 9 is disconnected from the contents; when the front shell 2 is closed, the door 9 remains connected to the contents. Because the door 9 can be disconnected from the contents, the front shell 2 can be separated from the chassis, allowing it to be opened. This openable design of the front shell 2 facilitates the inspection and maintenance of the internal components of the testing device.

[0043] In some embodiments, the door 9 is slidably mounted on the front housing to open or close the exchange opening 10, with the loading section moving along with the door 9. However, the sliding arrangement is structurally complex, the door 9 has a wide range of motion, occupies a large space, and is not conducive to the installation and arrangement of the detection device. Therefore, in this embodiment, the door 9 is rotatably connected to the chassis, and the door 9 opens or closes the exchange opening 10 by rotation. The rotation axis of the door 9 is perpendicular to the direction of movement of the loading section. The rotatable arrangement has the advantages of simple structure and small space occupation.

[0044] In this embodiment, the front shell 2 is rotatably connected to the chassis, and the rotation axis of the front shell 2 is parallel to the rotation axis of the door 9. The front shell 2 is opened or closed by rotation. In some embodiments, the front shell 2 can also be slidably connected or directly detachably connected to the chassis to enable the opening of the front shell 2. Compared with sliding or detachable connections, rotatable connections occupy less space, have a simpler structure, and are easier to operate. Specifically, the loading part is provided with a moving pin 28, which is a protrusion that passes through the moving groove 36. The connecting rod 8 is rotatably connected to the loading part through the moving pin 28.

[0045] In this embodiment, one end of the motion groove 36 is a push engagement point 37, and the other end is a pull engagement point 38. When the door 9 is opened, the pull engagement point 38 engages with the motion pin 28, pulling the loading part from its initial position toward the exchange opening 10. When the door 9 is closed, the push engagement point 37 engages with the motion pin 28, pushing the loading part from the exchange opening 10 toward its initial position. One end of the disengagement groove 35 is connected to the push engagement point 37, and the other end of the disengagement groove 35 is a disengagement opening 39, through which the motion pin 28 can disengage from the connecting rod 8.

[0046] During the opening of the front shell 2, the direction of movement of the front shell 2 is different from the direction of movement of the door 9 during the opening of the door 9. Therefore, whether the loading part is connected to the connecting rod 8 can be determined by changing the direction of movement of the loading part relative to the connecting rod 8. Specifically, for example... Figure 4 and Figure 6 As shown, the shape of the motion groove 36 is adapted to the motion trajectory of the door body 9, and the shape of the disengagement groove 35 is adapted to the motion trajectory of the front shell 2.

[0047] In this embodiment, the release groove 35 is an arc-shaped groove with its axis of rotation on the front housing 2 and its radius being the distance between the axis of the moving pin 28 and the axis of rotation of the front housing 2 when the loading part is in its initial position. When the front housing 2 is open, the moving pin 28 can move relative to the connecting rod 8 along the release groove 35 and disengage from the connecting rod 8 through the release opening 39. The movement groove 36 is also an arc-shaped groove with its center on the axis of rotation of the connecting rod 8 and its radius being the distance between the axis of the moving pin 28 and the axis of rotation of the door body 9 when the loading part is in its initial position. Therefore, when the front housing 2 is closed and the door body 9 is open or closed, the moving pin can only move relative to the connecting rod 8 along the movement groove 36 and will not enter the release groove 35, preventing the moving pin 28 from disengaging from the release groove 35.

[0048] In this embodiment, there is damping between the door body 9 and the connecting rod 8. When the torque on the connecting rod 8 is greater than the damping, the connecting rod 8 moves relative to the door body 9. When the torque on the connecting rod 8 is less than or equal to the damping, the connecting rod 8 remains stationary relative to the door body 9. When the torque between the connecting rod 8 and the door body 9 is less than or equal to the damping, the connecting rod 8 and the door body 9 remain relatively stationary. When the torque between the connecting rod 8 and the door body 9 is greater than the damping, the connecting rod 8 and the door body 9 rotate relative to each other. The damping between the door body 9 and the connecting rod 8 is at least greater than the torque generated by the connecting rod 8 under gravity. Therefore, when the door body 9 or the front shell 2 begins to rotate, the damping can maintain the relative position between the connecting rod 8 and the door body 9, preventing it from changing arbitrarily under the influence of gravity and other factors, thus preventing the moving pin 28 from accidentally entering the release groove 35 or the moving groove 36.

[0049] In some embodiments, damping can be generated by the frictional torque of the rotating pair between the link 8 and the door 9, so that when the torque on the link 8 is less than or equal to the damping, the link 8 remains stationary relative to the door 9. However, as the number of rotations of the link 8 increases, the frictional torque may change, which is detrimental to the stability of the link 8. Therefore, in this embodiment, a damper is provided between the link 8 and the door 9 to increase the rotational resistance between the link 8 and the door 9. Specifically, such as... Figure 2As shown, the damper includes a locking shaft, a locking spring, and a locking nut 17. A lug 20 is provided on the door body 9, and the connecting rod is rotatably connected to the lug 20 of the door body 9 via the locking shaft. The locking nut 17 is screwed onto the locking shaft, and the locking spring is located between the locking nut 17 and the connecting rod 8. Under the action of the locking nut 17, the locking spring presses the connecting rod 8 onto the door body 9. By adjusting the position of the locking nut 17 on the locking shaft, the compression degree of the locking spring can be adjusted, thereby adjusting the pressure between the connecting rod and the door body 9. In this embodiment, there are two locking nuts 17, which can play a role in preventing loosening. With the same coefficient of friction, adjusting the compression of the locking spring can adjust the friction between the door body 9 and the connecting rod 8, thereby adjusting the damping magnitude of the damper. In this embodiment, a rotating bushing 16 is provided on the locking shaft, located between the connecting rod 8 and the lug 20, reducing wear on the connecting rod 8 and the lug 20. The compression spring uses a butterfly washer 19. The butterfly washer 19 is small in size, which reduces the axial dimension of the locking shaft and facilitates the installation of the damper.

[0050] The present invention also provides a detection device, including a chassis and the above-mentioned door structure. A support is fixedly disposed inside the chassis, and a loading part is disposed on the support. The loading part moves on the support, and the support is used to constrain the movement trajectory of the loading part.

[0051] like Figure 1 As shown, one side of the chassis is the operating side 1, and the side of the chassis adjacent to the operating side 1 is the bottom side 6. In this embodiment, the automatic sample injection component of the detection device is installed near the bottom side 6 of the chassis. When the detection device is running, the operator needs to frequently monitor the automatic sample injection component in order to promptly detect and resolve problems such as sample injection jamming.

[0052] The operator performs operations and observations on the operating side 1. A clearance surface 7 is provided between the bottom side 6 and the operating side 1, and the clearance surface 7 is arranged along the line connecting the operator and the automatic sample introduction component. In this embodiment, the exchange opening 10 is located close to the operating side 1, which facilitates the operator in changing the fluorescent reagent bag 5. The exchange opening 10 is opened on the clearance surface 7, which is compact in structure, increases the remaining area of ​​the operating side 1, and facilitates arrangement.

[0053] In this embodiment, the side of the chassis opposite to the exchange opening 10 is the back side 4, and the connecting rod 8 connects the door 9 and the loading section. Therefore, during the opening of the door 9, the door 9 moves outward from the chassis, and the door 9, through the connecting rod, can drive the contents to move from the back side 4 toward the exchange opening 10 along with the loading section. During the closing of the door 9, the door 9 moves inward from the chassis, and the door 9, through the connecting rod 8, can drive the contents to move from the exchange opening 10 toward the back side 4.

[0054] Specifically, the loading section is mounted on the support section. One end of the support section is connected to the back side 4 of the chassis, and the other end of the support section faces the exchange opening 10. One end of the connecting rod 8 is connected to the door 9, and the other end of the connecting rod 8 is connected to the loading section. The loading section is used to load the contents, and the door 9 can drive the contents to slide on the support section along with the loading section via the connecting rod 8.

[0055] Under normal use, door 9 is usually closed, and the contents are typically located away from the exchange opening 10 and closer to the back side 4. Therefore, the support is located on the back side 4, resulting in less torque exerted by the contents on the connection point between the support and the chassis. While meeting usage requirements and keeping other conditions constant, the support can be made less robust, smaller, and lighter.

[0056] Specifically, such as Figure 3 As shown, in this embodiment, the support part is a sliding groove plate 12. A guide groove 13 is formed on the sliding groove plate 12 from the back side 4 towards the exchange opening 10. A sliding shaft is provided on the loading part for sliding within the guide groove 13. The sliding shaft is within the guide groove 13, and the loading part slides along the guide groove 13. The guide groove 13 can guide the movement of the loading part, constrain the loading part to prevent it from falling off, and also reduce the mass of the support part. The support part can also be a guide rod. Compared to a guide rod, the sliding groove plate 12 simplifies the structure of the loading part, resulting in less moving mass and more flexible and convenient movement.

[0057] In this embodiment, there are two sliding shafts with parallel axes, arranged within the guide groove 13. The two sliding shafts cooperate with the guide groove 13 to constrain the angle of the loading section, preventing it from tipping over during movement. The loading section includes a placement plate 23 with a loading notch 32. The loading notch 32 engages with the fluorescent reagent bag 5, securing it to the placement plate 23. The placement plate 23 is horizontally positioned, ensuring the fluorescent reagent bag 5 remains horizontal during movement and preventing tipping. In this embodiment, the angle between the line connecting the two sliding shafts and the placement plate 23 is the same as the angle between the guide groove 13 and the horizontal plane, thus keeping the placement plate 23 horizontal as the sliding shafts move within the guide groove 13. Rolling bearings are provided on the sliding shafts, allowing them to slide within the guide groove 13. These bearings reduce friction between the placement plate 23 and the guide groove 13, resulting in smoother movement of the loading section.

[0058] Specifically, one end of the connecting rod 8 is rotatably connected to the door body 9 away from its rotation axis, while the other end of the connecting rod 8 is rotatably connected to the loading part. When the door body 9 rotates to open or close, the door body 9 drives the loading part to slide on the support part via the connecting rod 8. The connection point between the connecting rod 8 and the door body 9 is far from the rotation axis of the door body 9, which increases the displacement of the connecting rod 8 when the door body 9 rotates, thus increasing the range of motion of the loading part.

[0059] like Figure 2 As shown, in this embodiment, one end of the door 9 is rotatably mounted on the housing, and the connection point between the connecting rod 8 and the door 9 is close to the other end of the door 9. Specifically, a rotating shaft 14 is provided on one end of the door 9, and the door 9 is rotatably connected to the housing through the rotating shaft 14.

[0060] Specifically, such as Figure 3 As shown, in this embodiment, the placement plate 23 is a sheet metal part, bent to have a mounting portion 31 for mounting the rotating bearing 29. The rotating bearing 29 is mounted on the mounting portion 31 of the placement plate 23 via a locking screw 22 and a bearing baffle 27. A positioning bushing 30 is provided between the locking screw 22 and the rotating bearing 29. The positioning bushing 30 can cooperate with the bearing baffle 27 to constrain the position of the rotating bearing 29 and prevent wear between the rotating bearing 29 and the placement plate 23. In this embodiment, a moving pin 28 is provided on the bearing baffle 27. The moving pin 28 is connected to the placement plate 23 as a whole via the bearing baffle 27 and the locking screw 22. The connecting rod 8 drives the loading part to move via the moving pin 28.

[0061] A connecting lock 11 can be installed between the door body 9 and the housing, and the door body 9 is kept closed by the connecting lock 11. In this embodiment, the connecting lock 11 is a push-spring lock, which is convenient to open and close and suitable for opening and closing the rotating door body 9.

[0062] like Figure 2 As shown, the loading part is made of magnetic material, and an attraction magnet 24 is installed inside the chassis at the position corresponding to the loading part. The attraction magnet 24 can attract the loading part. When the loading part is in the attraction direction of the attraction magnet 24 and the force it experiences is less than the attraction force of the attraction magnet 24, the attraction magnet 24 keeps the loading part and the chassis relatively stationary. When the loading part is in the attraction direction of the attraction magnet 24 and the force it experiences is greater than the attraction force of the attraction magnet 24, the loading part separates from the attraction magnet 24. When the door 9 is opened and the moving pin 28 moves between the pushing engagement point 37 and the pulling engagement point 38, the attraction magnet 24 keeps the loading part and the chassis relatively stationary.

[0063] In this embodiment, a mounting block 25 is provided on the back side 4 of the chassis corresponding to the loading part, and an attractive magnet 24 is provided on the mounting block 25. A cushioning foam 26 is also provided on the mounting block 25 corresponding to the loading part. When the loading part approaches the back side 4 when the spring lock switch is pressed or in other situations, the cushioning foam 26 can provide cushioning to avoid interference damage between the loading part and the chassis.

[0064] like Figure 3As shown, in this embodiment, there is a magnetic piece 21 on the door body 9 corresponding to the position of the connecting lock 11. The connecting lock 11 is made of magnetic material and cooperates with the magnetic piece 21. When the door body 9 closes the exchange opening 10, the magnetic piece 21 keeps the door body 9 and the chassis attracted to each other.

[0065] like Figure 7 As shown, in this embodiment, when the fluorescent reagent bag 5 needs to be replaced, pressing the position corresponding to the pressing spring lock on the door body 9 pushes the movement groove 36 between the engagement point 37 and the pulling engagement point 38 to a free stroke. When the moving pin 28 moves along the movement groove 36 within the free stroke, the resistance between the pull rod 8 and the moving pin 28 is very small. Therefore, pressing the spring lock can pop the door body 9 out of the exchange opening 10 a certain distance until the pulling engagement point 38 contacts the moving pin 28. After the door body 9 pops out a certain distance, a certain gap is opened between the door body 9 and the front shell 2, which allows the operator to manually continue to pull the popped-out door body 9 through the gap, so that the door body 9 rotates around the rotating shaft 14.

[0066] At this time, since the connection point between the connecting rod 8 and the door body 9 is far from the rotation axis 14, the connecting rod 8 also moves outward when the door body 9 rotates. At the beginning of the outward movement of the connecting rod 8, the loading part remains stationary due to the action of the attracting magnet 24, and the damper keeps the connecting rod and the door body 9 relatively stationary. At this time, the moving pin 28 moves in a circular motion relative to the door body 9 with the rotation axis 14 of the door body 9 as the axis and the distance from the moving pin 28 to the axis of the rotation axis 14 as the radius. That is, the moving pin 28 moves from the pushing engagement point 37 along the moving groove 36 towards the pulling engagement point 38 until the moving pin 28 reaches the pulling engagement point 38.

[0067] like Figure 8 As shown, after the moving pin 28 reaches the pulling engagement point 38, the door body 9 continues to be pulled. When the pulling force exceeds the attraction force of the attraction magnet 24, the loading part separates from the attraction magnet 24 and begins to move along the sliding groove plate 12 towards the exchange opening 10. At the same time, the torque between the connecting rod 8 and the door body 9 is greater than the damping of the damper, and the connecting rod 8 begins to rotate. The door body 9 is pulled until the loading part moves to the end of the guide groove 13 facing the exchange opening 10. The fluorescent reagent bag 5 on the loading part is replaced.

[0068] like Figure 9As shown, after the fluorescent reagent bag 5 is replaced, push the door 9. The moving pin 28 moves within the moving groove 36, from the pulling engagement point 38 to the pushing engagement point 37. Continue pushing the door 9. The pushing engagement point 37 of the connecting rod 8 acts on the moving pin 28, pushing the loading part along the guide groove 13 into the box. When the door 9 closes the exchange opening 10, the magnetic plate 21 on the door 9 engages the connecting lock 11, keeping the door 9 closed. At the same time, the loading part also enters the range of action of the magnetic magnet 24, engaging the loading part. When the door 9 is closed, it needs to be pressed, so that the pressing spring lock completes the connection between the door 9 and the chassis. At this time, the loading part will move further into the chassis. The cushioning foam 26 can cushion the loading part, preventing hard interference between the loading part and the chassis.

[0069] like Figure 10 As shown, when the chassis needs to be opened for maintenance, door 9 must be in the closed state, at which time the moving pin 28 of the loading part is at the push engagement point 37. Figure 1 As shown, the front housing 2 is opened around its rotation axis. At this time, the moving pin 28 moves in a circle relative to the front housing 2, with the rotation axis of the front housing 2 as the axis of rotation and the distance between the moving pin 28 and the rotation axis of the front housing 2 as the radius. That is, the front housing 2 moves along the release groove 35 until the moving pin 28 leaves the connecting rod 8 from the release opening 39. After the moving pin 28 leaves the connecting rod 8, the front housing 2 can continue to rotate and open. Simultaneously, after the front housing 2 is opened, the attracting magnet 24 can keep the loading part in a fixed position, and the damper can keep the relative position between the connecting rod 8 and the door 9 fixed. Therefore, when maintenance is completed and the front housing 2 is closed, the moving pin 28 can enter the moving groove 36 from the release opening 39 along the release groove 35 and reconnect with the connecting rod 8.

[0070] In other embodiments, such as Figure 5 As shown, a release groove 35 is directly formed on the motion groove 36. The extension direction of the release groove 35 intersects the extension direction of the motion groove 36, allowing the motion pin 28 to disengage from the connecting rod 8 via the release groove 35. Therefore, when the door 9 is normally opened and closed, the connecting rod 8 can maintain its connection with the loading part. When it is necessary to open the front cover 2, the door 9 is opened first, and then the operator reaches into the chassis through the exchange opening 10 and manually pushes the motion pin 28 out of the release opening 39.

[0071] When the chassis needs to be opened for maintenance, in order to disengage the connecting rod 8 from the moving pin 28, the door 9 must first be opened, and the loading section pulled out to the exchange opening 10. At this time, since the connecting rod 8 can rotate, the loading section can move along the guide groove 13, and the door 9 can also be flipped upwards, the connecting rod 8 can be easily removed from the moving pin 28 with the cooperation of these three movements. However, it should be noted that after unlocking the connecting rod 8 from the moving pin 28, the loading section needs to be manually pushed into the chassis, and it should be ensured that the loading section is attracted by the magnet 24. Then close the door 9 and flip the front cover 2 for maintenance.

[0072] After the maintenance is completed, first close the front cover 2, then open the door 9, manually drag the loading unit from inside the chassis to the exchange opening 10, and disengage the moving pin 28 from the connecting rod 8 through the opening 39 and insert it into the push engagement point 37 of the moving slot 36. Finally, close the door 9 to complete the entire maintenance.

[0073] As described above, in this embodiment, the connecting rod can be connected to both the door and the loading section for loading contents. When the door opens or closes, the loading section and the contents on it can move accordingly, facilitating the loading and unloading of contents. Simultaneously, the connecting rod is provided with a mounting groove, allowing it to separate from the loading section or the door, thereby enabling the front cover to be opened for easy inspection of the internal components of the detection device.

[0074] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
