Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment, specifically to a sample injection device and testing equipment for test tubes. Background Technology

[0002] Currently, automated testing equipment plays a crucial role in the processing of blood collection tubes. This equipment needs to precisely execute steps such as tube gripping, testing, and subsequent tube rack retrieval. Traditional testing equipment uses a fixed blocking structure and a separate power source to achieve the positioning and deployment of the tube rack. Specifically, during the testing phase, to prevent the tube rack from tilting or moving due to lateral forces, a fixed, immovable blocking component is typically used to ensure the stability of the rack during testing. However, after testing, the tube rack needs to be moved from the testing position to the retrieval position. Traditional equipment often relies on an additional power source and a complex transmission system to complete this task.

[0003] This design has significant limitations. Using multiple power sources not only increases the cost of the equipment but also makes the overall structure more complex, leading to increased difficulty in program control, maintenance, and troubleshooting. Secondly, the use of multiple power sources and a complex structure restricts the spatial layout of the equipment, making the already cramped working environment even more confined and reducing work efficiency.

[0004] As can be seen from the above, the sample introduction device in the existing technology has the problems of complex structure and reduced working efficiency. Utility Model Content

[0005] The main objective of this invention is to provide a sample injection device and a testing device for test tubes, in order to solve the problems of complex structure and reduced working efficiency of existing sample injection devices.

[0006] To achieve the above objectives, according to one aspect of the present invention, a sample injection device for test tubes is provided.

When the pushing part is in the third position, the limiting part and the pushing part are arranged on both sides of the mounting plate along the width direction of the frame. When the pushing part is switched to the fourth position, the pushing part moves toward the limiting part and pushes the carrier to disengage the carrier from the mounting plate. The driving structure is drivenly connected to the limiting component and the pushing component respectively. The driving structure provides driving force for the limiting part to switch from the first position to the second position and for the pushing part to switch from the third position to the fourth position.

[0007] Furthermore, the frame also includes a support plate disposed on one side of the mounting plate along the width direction. The support plate and the limiting part are disposed on the same side of the mounting plate. The support plate has a through hole. When the limiting part is in the first position, at least a portion of the limiting part extends through the through hole to the top of the mounting plate. When the pushing part is switched to the fourth position, it is used to drive the carrier to move to the support plate.

[0008] Furthermore, along the width direction of the frame, the drive assembly is located on the side of the mounting plate away from the limiting part. The drive assembly includes a drive member, which is located on the frame. The drive structure includes a turntable, and the drive member is driven to connect with the turntable. The turntable has a first structure, which drives and cooperates with the limiting assembly to provide driving force for the limiting part to switch from a first position to a second position. The turntable also has a second structure, which drives and cooperates with the pushing assembly to provide driving force for the pushing part to switch from a third position to a fourth position.

[0009] Furthermore, the first structure is a first groove structure, and the limiting component includes a first plate structure and a connecting structure. The first plate structure has a first protruding post at its first end, and the connecting structure has a movable part that is slidably disposed along the width direction of the frame. The second end of the first plate structure is connected to the movable part, and the connecting structure also has an arc-shaped connecting arm. The two ends of the connecting arm are respectively rotatably disposed on the movable part and the limiting part. When the limiting part is in the first position, at least a portion of the first protruding post is disposed inside the first groove structure; when the limiting part is switched to the second position, the first protruding post is disposed outside the first groove structure.

[0010] Furthermore, the connecting structure includes a second plate structure and a shaft structure. There are two second plate structures, which are spaced apart along the width direction of the frame. The shaft structure is located between the two second plate structures. The moving part is a moving block, which is slidably mounted on the shaft structure. Along the length direction of the frame, one end of the moving block is connected to the first plate structure, and the other end of the moving block is connected to the connecting arm.

[0011] Furthermore, the second structure is a second protruding post, and the pushing assembly also includes a connecting plate disposed on the bottom surface of the pushing part, the connecting plate having a second groove structure; when the pushing part is in the third position, the second protruding post is disposed on the outside of the second groove structure; when the pushing part is in the fourth position, at least a portion of the second protruding post is disposed inside the second groove structure and abuts against the inner wall of the second groove structure.

[0012] Furthermore, the axis of the turntable is co-located with the length direction of the frame; and / or the frame also includes a protective frame, which forms a protective space, a drive unit is disposed in the protective space, the turntable is disposed outside the protective space, and the output shaft of the drive unit passes through the protective frame and is connected to the turntable.

[0013] Furthermore, the sample injection device for the test tube further includes: at least one first sliding assembly, the limiting part being a limiting plate, the first sliding assembly including a first slide bar and a first slide rail extending along the height direction of the frame, the first slide rail having a first slide groove that slides with the first slide bar; one of the first slide bar and the first slide rail being disposed on the limiting plate, and the other being disposed on the frame; and / or at least one second sliding assembly, the pushing part being a push plate, the second sliding assembly including a second slide bar and a second slide rail extending along the width direction of the frame; the second slide rail having a second slide groove that slides with the second slide bar, one of the second slide bar and the second slide rail being disposed on the push plate, and the other being disposed on the frame.

[0014] Furthermore, the sample injection device for the test tube also includes a conveyor belt disposed on the mounting plate. The conveyor belt is positioned between the carrier and the mounting plate along the height direction of the frame, and the conveyor belt is used to drive the carrier to move along the length direction of the frame.

[0015] According to another aspect of the present invention, a testing device is provided, which includes the above-described sample injection device for test tubes.

[0016] The present invention provides a sample introduction device for test tubes, comprising a frame, a carrier, a drive assembly, a limiting assembly, and a pushing assembly. A single drive structure serves as the power source, enabling reciprocating motion of the carrier in both positioning and ejection directions. Specifically, the limiting part is movable along the height of the frame.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0027] To address the issues of complex structure and reduced efficiency of existing sample introduction devices, this embodiment provides a sample introduction device for test tubes, used to move test tubes to a target location.

[0028] like Figures 1 to 4As shown, the sample injection device for test tubes includes a frame 10, a carrier 70, a drive assembly 20, a limiting assembly 30, and a pushing assembly 40. The frame 10 includes a mounting plate 110 and a support plate 120 disposed on one side of the mounting plate 110. The carrier 70 is disposed on the mounting plate 110 and has a mounting slot 710 for placing test tubes. The drive assembly 20 is disposed on the frame 10 and has a drive structure 220. The limiting assembly 30 includes at least a limiting part 3 that is movable along the height direction of the frame 10. 10. The limiting part 310 has a switchable first position and a second position. The pushing component 40 includes at least a pushing part 410 that is movably disposed along the width direction of the frame 10. The pushing part 410 has a switchable third position and a fourth position. The driving structure 220 is drivenly connected to the limiting component 30 and the pushing component 40 respectively. The driving structure 220 provides driving force for the limiting part 310 to switch from the first position to the second position and provides driving force for the pushing part 410 to switch from the third position to the fourth position.

[0029] The limiting part 310 is disposed on one side of the mounting plate 110 along the width direction of the frame 10. That is, regardless of whether the limiting part 310 is in the first position or the second position, it is always disposed on one side of the mounting plate 110 along the width direction of the frame 10. The limiting part 310 has a first position and a second position in which it is raised and lowered along the height direction of the frame 10. When the limiting part 310 is in the first position, at least a part of it is disposed above the mounting plate 110 to abut against the side of the carrier 70 for limiting. At this time, the limiting part 310 has a guiding and limiting function to prevent the carrier 70 from tilting or shifting, thereby ensuring the stability of the carrier 70 installation. When the limiting part 310 is in the second position, it is disposed on the lower side of the mounting plate 110 to avoid the carrier 70 and release the limitation of the carrier 70 in the width direction of the frame 10.

[0030] The frame 10 also includes a base plate 130 and a support frame, with the mounting plate 110 and the support plate 120 mounted on the base plate 130 via the support frame.

[0031] When the pushing part 410 is in the third position, the limiting part 310 and the pushing part 410 are arranged on both sides of the mounting plate 110 along the width direction of the frame 10. At this time, there is no force between the pushing part 410 and the carrier 70. In the setting position, the pushing part 410 can be spaced apart from the carrier 70 or be attached to it. When the pushing part 410 switches to the fourth position, the pushing part 410 moves toward the limiting part 310 and pushes the carrier 70 to disengage the carrier 70 from the mounting plate 110. At this time, the limiting part 310 switches to the second position, and the pushing part 410 can push the carrier 70 to move the carrier 70 onto the support plate 120.

[0032] The length direction of frame 10 is Figure 1 As shown in the X direction, the width direction of the frame 10 is... Figure 1 As shown in the Y direction, the height direction of the frame 10 is... Figure 1 The Z direction is shown.

[0033] Specifically, the limiting part 310 is a limiting plate, which limits or avoids the carrier 70 through the lifting and lowering movement of the limiting plate; the pushing part 410 is a pushing plate, which moves along the width direction of the frame 10 to push the carrier 70 away from the mounting plate 110 and move it onto the support plate 120.

[0034] In this embodiment, the sample injection device for test tubes includes a frame 10, a carrier 70, a drive assembly 20, a limiting assembly 30, and a pushing assembly 40. A drive structure 220 serves as the power source to achieve reciprocating motion of the carrier 70 in both positioning and ejection directions. Specifically, the limiting part 310 is movably disposed along the height direction of the frame 10. When in the first position, the limiting part 310 contacts the side of the carrier 70, restricting the position of the carrier 70 and ensuring its stability during loading and unloading. When switched to the second position, the limiting part 310 descends, providing clearance for the carrier 70. The pushing part 410 moves along the width direction of the frame 10. When in the third position, it maintains a certain distance from the limiting part 310, not interfering with the carrier 70. When switched to the fourth position, the pushing part 410 moves towards the limiting part 310, pushing against the carrier 70. This application effectively solves the problem of reliably positioning and launching the test tube carrier 70 using a single power source in a compact space, thereby simplifying control, reducing costs, and improving space utilization.

[0035] like Figures 2 to 4 As shown, the support plate 120 and the limiting part 310 are disposed on the same side of the mounting plate 110. The support plate 120 has a through hole. When the limiting part 310 is in the first position, at least a portion of the limiting part 310 extends through the through hole to the top of the mounting plate 110.

[0036] The connection between the support plate 120 and the mounting plate 110 can be integrally formed or detachably connected by fasteners or other means.

[0037] Specifically, the through hole is provided along the height direction of the frame 10 to accommodate the switching of the limiting part 310 between the first position and the second position. The through hole allows the limiting part 310 to pass through and has the effect of guiding and limiting the limiting part 310, so as to ensure the precise switching of the limiting part 310 between the first position and the second position, which helps to improve efficiency.

[0038] In this embodiment, the carrier 70, detached from the mounting plate 110, is placed on the support plate 120, thereby enabling the carrier 70 to be placed so that the testing device can test the test tubes on the carrier 70.

[0039] like Figure 3 and Figure 4 As shown, along the width direction of the frame 10, the drive assembly 20 is disposed on the side of the mounting plate 110 away from the limiting part 310.

[0040] Specifically, the drive assembly 20 includes a drive component 210 and a drive structure 220. The drive component 210 is disposed on the base plate 130 of the frame 10, and the drive structure 220 includes a turntable. The drive component 210 is driven and connected to the turntable.

[0041] Among them, the driving component 210 is a motor, and the turntable is rotatably set under the driving action of the driving component 210.

[0042] The turntable has a first structure 240, which works in conjunction with the limiting component 30 to provide driving force for the limiting part 310 to switch from the first position to the second position, thereby realizing the lifting and lowering movement of the limiting part 310.

[0043] The turntable has a second structure 230, which is driven to cooperate with the push assembly 40 to provide driving force for the push unit 410 to switch between the third position and the fourth position, thereby realizing the reciprocating movement of the push unit 410 along the width direction of the frame 10.

[0044] In this embodiment, the first structure 240 and the second structure 230 on the turntable are used to drive the limiting component 30 and the pushing component 40, respectively. Under the action of the driving member 210, the turntable rotates, and the first structure 240 and the second structure 230 on the turntable rotate synchronously to drive the limiting component 30 and the pushing component 40, respectively. The first structure 240 and the second structure 230 of this application independently cooperate with the limiting component 30 and the pushing component 40, ensuring that different structures on the same turntable can drive the limiting component 30 and the pushing component 40 to perform actions. This application only requires one turntable to coordinate the positioning and ejection functions of the carrier 70, simplifying the structural setup and improving the sample feeding efficiency of the device.

[0045] In this embodiment, the frame 10 also includes a protective frame 140, which is disposed on the base plate 130 and forms a protective space 141. A drive component 210 is disposed in the protective space 141, and a turntable is disposed outside the protective space 141. The output shaft of the drive component 210 passes through the protective frame 140 and connects to the turntable. The structural design of the protective frame 140 in this application achieves the effect of positioning and protecting the drive component 210, ensuring the safety of the structure. The pushing component 40 in this application can be disposed on the top surface of the protective frame 140, thereby enabling the protective frame 140 to compensate for the height of the pushing component 40, ensuring that the pushing part 410 can be aligned with the carrier 70 along the height direction of the frame 10.

[0046] In this embodiment, the axis of the turntable is in the same direction as the length direction of the frame 10, so that when the turntable rotates around the axis, the first structure 240 and the second structure 230 move in the plane formed by the height and width directions of the frame 10 to adapt to the movement of the pushing component 40 along the width direction of the frame 10 and the movement of the limiting component 30 along the height direction of the frame 10.

[0047] like Figure 3 and Figure 4 As shown, the first structure 240 is a first groove structure, and the limiting component 30 includes a first plate structure 330 and a connecting structure 340. The first end of the first plate structure 330 has a first protrusion 320, and the connecting structure 340 has a movable part 343 that is slidably disposed along the width direction of the frame 10. The second end of the first plate structure 330 is connected to the movable part 343. The connecting structure 340 also has an arc-shaped connecting arm 344, and the two ends of the connecting arm 344 are respectively rotatably disposed on the movable part 343 and the limiting part 310.

[0048] Specifically, when the limiting part 310 is in the first position, at least a portion of the first protrusion 320 is disposed inside the first groove structure; when the limiting part 310 is switched to the second position, the first protrusion 320 is disposed outside the first groove structure.

[0049] In this embodiment, the limiting component 30 further includes a reset element, which is a spring. The spring is arranged along the height direction of the frame 10, with one end of the spring connected to the limiting part 310 and the other end of the spring connected to the frame 10. The spring provides driving force for the limiting part 310 to switch from the second position to the first position. Of course, it is not limited to the above-described spring structure; the limiting part 310 can also be switched from the second position to the first position manually.

[0050] During the rotation of the turntable driven by the drive component 210, the first protrusion 320 is located inside the first groove structure, and the limiting part 310 is in the first position. As the turntable rotates, the inner wall of the first groove structure abuts against the outer peripheral surface of the first protrusion 320 and drives the first protrusion 320 to move away from the limiting part 310. The first protrusion 320 drives the moving part 343 of the connecting structure 340 to move along the width direction of the frame 10 through the first plate structure 330. While the moving part 343 moves, it pulls one end of the connecting arm 344 to move, thereby realizing that the other end of the connecting arm 344 moves towards the bottom plate 130 along the height direction of the frame 10. The connecting arm 344 drives the limiting part 310 to move towards the bottom plate 130 at the same time. At the same time, the first protrusion 320 slides and engages with the inner wall of the first groove structure and moves towards the groove opening of the first groove structure. As the turntable continues to rotate, the first protrusion 320 disengages from the groove opening of the first groove structure, the limiting component 30 stops moving, and the limiting part 310 switches to the second position. When the drive unit 210 drives the turntable to move in the opposite direction, as the turntable rotates, the contact between the turntable and the first protrusion 320 is released. Under the action of the elastic force of the spring, the limiting part 310 moves toward the first position, and then drives the connecting structure 340 and the first plate structure 330 to move synchronously through the connecting arm 344. At the same time, as the turntable rotates, the slot of the first groove structure cooperates with the first protrusion 320 to realize that the first protrusion 320 enters the first groove structure from the slot of the first groove structure.

[0051] In this embodiment, the first plate structure 330 is slidably mounted on the base plate 130 of the frame 10 along the width direction. The connecting arm 344 has an arc-shaped structure, and both ends are rotatably configured. This ensures that when the first end of the connecting arm 344 moves along the width direction of the frame 10, the other end of the connecting arm 344 can pull the limiting part 310 to move along the height direction of the frame 10. The arc of the connecting arm 344 can be adapted according to actual needs. In this embodiment, the two ends of the connecting arm 344 have hole structures along the length direction of the frame 10. The corresponding moving part 343 and the limiting part 310 have protruding shafts extending along the length direction of the frame 10. The two ends of the connecting arm 344 are sleeved on the two protruding shafts through the two hole structures, thereby achieving a rotatable connection. When the moving part 343 moves along the width direction of the frame 10, the connecting arm 344 and the limiting part 310 can be driven to move synchronously through the pressure between the inner wall of the hole structure and the protruding shaft.

[0052] In this embodiment, the connecting structure 340 includes a second plate structure 341 and a shaft structure 342. Two second plate structures 341 are provided and spaced apart along the width direction of the frame 10. The two second plate structures 341 are erected on the base plate 130 to stably support and position the shaft structure 342. The shaft structure 342 is disposed between the two second plate structures 341. The moving part 343 is a moving block, which is slidably disposed on the shaft structure 342. The shaft structure 342 is used to support and guide the moving block. Along the length direction of the frame 10, one end of the moving block is connected to the first plate structure 330, and the other end of the moving block is connected to the connecting arm 344. This reduces the volume of the moving block, simplifies the structure of the device, and improves space utilization.

[0053] like Figure 3 and Figure 4 As shown, the second structure 230 is a second protruding post, and the pushing assembly 40 also includes a connecting plate 420. The connecting plate 420 is disposed on the bottom surface of the pushing part 410, and the connecting plate 420 has a second groove structure 421.

[0054] Specifically, when the pushing part 410 is in the third position, the second protrusion is disposed on the outside of the second groove structure 421, and the groove opening of the second groove structure 421 is disposed facing the turntable; when the pushing part 410 is in the fourth position, at least a portion of the second protrusion is disposed inside the second groove structure 421 and abuts against the inner wall of the second groove structure 421.

[0055] During the rotation of the turntable driven by the drive component 210, the turntable drives the second protrusion to rotate. The second protrusion moves from the opening of the second groove structure 421 to the interior of the second groove structure 421. As the turntable rotates, the second protrusion presses against the inner wall of the groove of the second groove structure 421, thereby pushing the connecting plate 420 to move towards the limiting part 310 along the width direction of the frame 10. The connecting plate 420 drives the pushing part 410 to move synchronously. The pushing part 410 pushes the carrier 70 to move, thereby driving the carrier 70 onto the support plate 120. At this time, the pushing part 410 switches to the fourth position. When the turntable rotates in the opposite direction under the drive of the drive component 210, the second protrusion moves away from the limiting part 310 under the drive of the turntable and gradually exits the second groove structure 421. At this time, the pushing part 410 returns to the third position.

[0056] In this embodiment, the first structure 240 and the second structure 230 are spaced apart along the circumference of the turntable. That is, during the process of the drive member 210 driving the turntable to rotate, the first structure 240 first cooperates with the first protrusion 320 to realize the drive limiting part 310 switching from the first position to the second position. At this time, the first protrusion 320 disengages from the first groove structure. Then, the second structure 230 moves to the second protrusion and enters the interior of the second groove structure 421. Through the cooperation of the second groove structure 421 and the second protrusion, the turntable drive pushing part 410 switches from the third position to the fourth position. That is, the limiting part 310 first switches from the first position to the second position to avoid the carrier 70, and then the pushing part 410 switches from the third position to the fourth position. Correspondingly, when the drive member 210 drives the turntable to rotate in the opposite direction, the pushing part 410 first switches from the fourth position to the third position, and then the limiting part 310 switches from the second position to the first position under the drive of the spring. This application, through the structural arrangement of the rotating structure, the limiting part 310, and the pushing part 410, ensures that the pushing part 410 only starts to move after the limiting part 310 has completely retracted, thus avoiding interference between the two actions and enhancing the stability and safety of the equipment.

[0057] like Figure 3 and Figure 4 As shown, the sample injection device for test tubes also includes a first sliding assembly 50, which includes a first slide bar and a first slide rail extending along the height direction of the frame 10. The first slide rail has a first slide groove that slides in cooperation with the first slide bar.

[0058] The first slide bar and the first slide groove have a guiding and limiting function to ensure that the limiting part 310 can only move up and down along the height direction of the frame 10, thus ensuring the stability of the structure.

[0059] Specifically, one of the first slide bar and the first slide rail is disposed on the limiting part 310, and the other is disposed on the frame 10. That is, the positions of the first slide bar and the first slide rail are interchangeable. When the first slide bar is disposed on the limiting part 310, the first slide rail is disposed on the support frame of the frame 10; when the first slide bar is disposed on the support frame of the frame 10, the first slide rail is disposed on the limiting part 310.

[0060] In this embodiment, one or more first sliding components 50 are provided. When there are multiple first sliding components 50, the multiple first sliding components 50 are spaced apart along the length direction of the frame 10.

[0061] like Figure 3 and Figure 4 As shown, the sample injection device for test tubes also includes a second sliding assembly 60, which includes a second slide bar and a second slide rail extending along the width direction of the frame 10, and the second slide rail has a second slide groove that slides in cooperation with the second slide bar.

[0062] The combination of the second slide bar and the second slide groove serves as a guide and limiter, ensuring that the push plate can only slide along the width of the frame 10, thus guaranteeing the stability of the structure.

[0063] Specifically, one of the second slide bar and the second slide rail is disposed on the push plate, and the other is disposed on the frame 10. That is, when the second slide bar is disposed on the push plate, the second slide rail is disposed on the frame 10; when the second slide bar is disposed on the frame 10, the second slide rail is disposed on the push plate.

[0064] In this embodiment, one or more second sliding components 60 are provided. When there are multiple second sliding components 60, the multiple second sliding components 60 are spaced apart along the length direction of the frame 10.

[0065] like Figure 3 and Figure 4 As shown, the sample injection device for test tubes also includes a conveyor belt and a conveyor drive. The conveyor belt is rotatably mounted on rollers at both ends of the mounting plate 110. The portion of the conveyor belt along the height direction of the frame 10 is located between the carrier 70 and the mounting plate 110. The conveyor belt is used to provide drive for the carrier 70 to move along the length direction of the frame 10.

[0066] Specifically, the conveyor drive is mounted on the frame 10 and is connected to the roller drive. The conveyor drive drives the conveyor belt to rotate via the rollers, which in turn drives the carrier 70 to move. The conveyor drive is a motor, and the drive connection between the conveyor drive and the rollers can be a sprocket and chain structure. For example, sprockets can be mounted on the output shaft of the conveyor drive and on the rollers, with the two sprockets connected by a chain. Alternatively, the output shaft of the conveyor drive can be directly connected to the rollers.

[0067] In this embodiment, the carrier 70 may be slidably mounted on the mounting plate 110, and the conveyor belt may be provided with a mating structure that mates with the carrier 70 to drive the carrier 70 to move. The mating structure may be a tooth, a fastener, or an adhesive, etc. Alternatively, the carrier 70 may be placed on the conveyor belt so that the conveyor belt drives the carrier 70 to move.

[0068] In the embodiments of this application, the working process of the sample injection device for test tubes is as follows: First, the carrier 70 is conveyed to a designated position on the mounting plate 110 via a conveyor belt. At this time, the limiting part 310 in the limiting component 30 is in the first position, extending from above the mounting plate 110 and abutting against the side of the carrier 70 to prevent the carrier 70 from shifting or tipping under lateral force, ensuring its stability during the detection stage. Subsequently, when the test tube is detected, the driving component 210 of the driving component 20 is activated, and the driving component 210 begins to operate, driving the turntable to rotate. As the turntable rotates, the first structure 240 interacts with the limiting component 30, causing the limiting part 310 to switch to the second position and descend below the mounting plate 110, thereby making room for the movement of the carrier 70 and avoiding interference with subsequent actions. Next, the drive unit 210 continues to drive, and the second structure 230 of the turntable contacts the push assembly 40, triggering the push part 410 to move from the third position to the fourth position. At this time, the push part 410 moves towards the side where the limiting part 310 is located, contacts the side of the carrier 70, applies sufficient thrust, and guides the carrier 70 to slide smoothly towards the position of the support plate 120. Finally, the motor reverses, and through the reverse action of the drive structure 220 of the drive assembly 20, the push part 410 first returns to the third position, and then the limiting part 310 rises back to the first position under the action of the spring, ready for the next cycle operation. Throughout the process, the continuous operation of a single power source and the special design of the cam shape enable the switching of actions within a limited time, avoiding equipment malfunctions that may be caused by the simultaneous operation of two mechanisms, and ensuring the orderly and safe operation of the test tube carrier 70 throughout the entire sample injection, testing, and recovery process.

[0069] This embodiment also provides a detection device, which includes the sample injection device for test tubes described in the above embodiment. The detection device employs the sample injection device for test tubes described in the above embodiment, achieving simplification of structure and operation, reducing space occupation, and improving detection efficiency.

[0070] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0071] The sample introduction device for test tubes includes a frame 10, a carrier 70, a drive assembly 20, a limiting assembly 30, and a pushing assembly 40. A drive structure 220 serves as the power source to achieve reciprocating motion of the carrier 70 in both positioning and ejection directions. Specifically, the limiting part 310 is movable along the height direction of the frame 10. When in the first position, the limiting part 310 contacts the side of the carrier 70, restricting the position of the carrier 70 and ensuring its stability during loading and unloading. When switched to the second position, the limiting part 310 descends, providing clearance for the carrier 70. The pushing part 410 moves along the width direction of the frame 10. In the third position, it maintains a certain distance from the limiting part 310, not interfering with the carrier 70. When switched to the fourth position, the pushing part 410 moves towards the limiting part 310, pushing against the carrier 70. This application effectively solves the problem of reliably positioning and launching the test tube carrier 70 using a single power source in a compact space, thereby simplifying control, reducing costs, and improving space utilization.
