[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] When conducting experiments, it is necessary to test multiple samples simultaneously. Currently, when testing multiple samples simultaneously, multiple sample containers are installed in the fixed slots of the sample inlet plate. The sample inlet plate rotates inside the testing instrument to continuously test the samples in the multiple sample containers.

[0040] To accommodate sample containers of various sizes, the mounting slot is designed to be relatively large. When a smaller sample container is placed on the mounting slot, the sample container becomes unstable, affecting the detection of the sample inside. To solve or improve the problem of unstable sample container installation, this application provides a sample introduction device.

[0041] The following is combined with Figures 1 to 4 This describes an embodiment of the present application.

[0042] According to an embodiment of this application, a sample injection device is provided, including: a mounting plate 1, a support member 2, and at least one clamping mechanism 4.

[0043] Specifically, the side wall of the mounting plate 1 is provided with a mounting groove 101, and the surface of the mounting plate 1 is provided with at least one container mounting hole 102, which communicates with the mounting groove 101.

[0044] The support member 2 corresponds to the slot of the mounting groove 101, and the support member 2 is connected to the mounting plate 1 through multiple support rods 3;

[0045] The clamping mechanism 4 is connected to the support member 2. The clamping end of the clamping mechanism 4 is located in the mounting groove 101 and is used to clamp the container in the container mounting hole 102.

[0046] In this embodiment, the container is passed through the container mounting hole 102, and the bottom of the container abuts against the inner side wall of the mounting groove 101. There is a gap between the outer wall of the container and the container mounting hole 102, which causes the container to be unstable. The clamping end of the clamping mechanism 4 is located in the mounting groove 101, clamping the container in the container mounting hole 102 to improve the stability of the container.

[0047] In one embodiment, such as Figure 4 As shown, the clamping mechanism 4 includes:

[0048] The first clamping member 401 has one end rotatably connected to the support member 2, and the other end is located in the mounting groove 101 and has a first through hole 5. The first through hole 5 can be arranged coaxially with the container mounting hole 102.

[0049] The second clamping member 402 has one end rotatably connected to the support member 2, and the other end is located in the mounting groove 101 and has a second through hole 6. The second through hole 6 can be arranged coaxially with the container mounting hole 102. The first clamping member 401 and the second clamping member 402 are arranged offset along the axial direction of the container mounting hole 102.

[0050] The drive mechanism 403 is mounted on the support member 2. The drive mechanism 403 drives the first clamping member 401 and the second clamping member 402 to rotate in opposite directions or in opposite directions through the transmission assembly 404.

[0051] In this embodiment, such as Figure 4 As shown, the first clamping member 401 and the second clamping member 402 can rotate and switch between the first position and the second position under the action of the driving mechanism 403. In the first position, the first through hole 5, the second through hole 6 and the container mounting hole 102 are coaxially arranged, which makes it easy to pass the container through the container mounting hole 102, the first through hole 5 and the second through hole 6, so that the bottom of the container abuts against the inner side wall of the mounting groove 101 and the container is placed on the mounting plate 1.

[0052] The drive mechanism 403 drives the first clamping member 401 and the second clamping member 402 to rotate in opposite directions, so that the first clamping member 401 and the second clamping member 402 move away from each other until the first clamping member 401 and the second clamping member 402 are in the second position. The first through hole 5 and the second through hole 6 are not coaxially arranged. The side walls of the first through hole 5 and the second through hole 6 clamp the container and clamp the container in the container mounting hole 102.

[0053] Specifically, the drive mechanism 403 drives the first clamping member 401 and the second clamping member 402 located at one end of the mounting groove 101 to move closer or further away simultaneously via the transmission assembly 404.

[0054] In one embodiment, such as Figure 4 As shown, the drive mechanism 403 is a motor;

[0055] Transmission assembly 404 includes:

[0056] Screw 4041, one end of which is connected to the output shaft of the motor for transmission;

[0057] Connecting block 4042 has a threaded hole, which is screwed to screw rod 4041;

[0058] The first connecting rod 4043 is hinged at one end to the connecting block 4042 and at the other end to the first clamping member 401;

[0059] The second connecting rod 4044 is hinged at one end to the connecting block 4042 and at the other end to the second clamping member 402;

[0060] The first connecting rod 4043 and the second connecting rod 4044 are arranged symmetrically about the screw 4041.

[0061] In this embodiment, the motor drives the screw 4041 to rotate, and the rotation of the screw 4041 causes the connecting block 4042 to move along the length of the screw 4041. Figure 4 As shown, when the connecting block 4042 moves away from the motor along the axial direction of the screw 4041, the first connecting rod 4043 and the second connecting rod 4044 push the first clamping member 401 and the second clamping member 402 to rotate in opposite directions, driving the first clamping member 401 and the second clamping member 402 to move from the first position to the second position. The central axes of the first through hole 5 and the second through hole 6 are misaligned, clamping the container in the container mounting hole 102.

[0062] like Figure 2 and Figure 3 As shown, after the sample in the container is tested, when the container needs to be removed from the container mounting hole 102, the motor reverses and drives the connecting block 4042 to move closer to the motor along the axial direction of the screw 4041. The first connecting rod 4043 and the second connecting rod 4044 pull the first clamping member 401 and the second clamping member 402 to rotate in opposite directions, driving the first clamping member 401 and the second clamping member 402 to move from the second position to the first position. The central axes of the first through hole 5 and the second through hole 6 are coaxial, releasing the container and removing it from the container mounting hole 102.

[0063] Specifically, such as Figure 4 As shown, it also includes a first connecting post 4045 and a second connecting post 4046. One end of the first connecting post 4045 is fixed to the first clamping member 401, and the other end is hinged to the first connecting rod 4043. One end of the second connecting post 4046 is fixed to the second clamping member 402, and the other end is hinged to the second connecting rod 4044.

[0064] Specifically, such as Figure 4 As shown, it also includes four hinge seats 8, which are respectively disposed on both sides of the connecting block 4042 and on the first connecting post 4045 and the second connecting post 4046. The two ends of the first connecting rod 4043 are respectively hinged to the hinge seats 8 on the connecting block 4042, and the other end is hinged to the hinge seat 8 on the first connecting post 4045; the two ends of the second connecting rod 4044 are respectively hinged to the hinge seats 8 on the connecting block 4042, and the other end is hinged to the hinge seat 8 on the second connecting post 4046.

[0065] In one embodiment, such as Figure 1 and Figure 3 As shown, the mounting plate 1 is an annular plate, and the inner sidewall of the annular plate is provided with a mounting groove 101. The annular plate is provided with a plurality of container mounting holes 102, which are arranged at equal angles along the circumference of the annular plate.

[0066] like Figure 1 As shown, multiple clamping mechanisms 4 are provided, and the multiple clamping mechanisms 4 are arranged in a one-to-one correspondence with the multiple container mounting holes 102.

[0067] In this embodiment, such as Figure 1 As shown, the annular plate is provided with multiple container mounting holes 102, which can hold multiple containers simultaneously. The multiple container mounting holes 102 are arranged at equal angles along the circumference of the annular plate. After the sample in one container is tested, it is only necessary to rotate it by a preset angle to test the sample in the next container. The container in each container mounting hole 102 is clamped by a clamping mechanism 4.

[0068] Specifically, the container mounting holes 102 have 12 holes, with a preset angle of 30°.

[0069] In one embodiment, the support member 2 is a connecting column, which is coaxially arranged with the annular plate. The side wall of the connecting column is connected to the annular plate through multiple support rods 3. The side wall of the connecting column is provided with an annular groove 201 corresponding to the mounting groove 101. The first clamping member 401 and the second clamping member 402 are rotatably connected to the annular groove 201 through a rotating connector.

[0070] In this embodiment, such as Figure 1 As shown, the connecting column and the annular plate are coaxially arranged, which can ensure that the lengths of the multiple first clamping members 401 and the multiple second clamping members 402 are the same.

[0071] Specifically, the first clamping member 401 and the second clamping member 402 are both provided with through holes at one end near the annular groove 201. The rotating connecting member is a pin, which passes through the through holes of the first clamping member 401 and the second clamping member 402. The pin is rotatably connected to the through holes, and the two ends of the pin are respectively connected to the two side walls of the annular groove 201.

[0072] Specifically, the pin is parallel to the axis of the first through hole 5.

[0073] In one embodiment, such as Figure 2 As shown, it also includes a support column 7, one end of which is connected to the connecting column, and the support column 7 and the connecting column are arranged coaxially.

[0074] In this embodiment, the support column 7 is arranged coaxially with the connecting column, which facilitates the support of the connecting column.

[0075] Specifically, the support column 7 can be connected to the drive device through a transmission component, which drives the support column 7 to rotate, thereby causing the connecting column to rotate by a preset angle, and then transporting the container to the sample detection position for detection.

[0076] In one embodiment, such as Figure 2 and Figure 3 As shown, the inner sidewall of the mounting groove 101 is provided with multiple placement grooves 1011, and the openings of the multiple placement grooves 1011 are arranged in a one-to-one correspondence with the multiple container mounting holes 102.

[0077] In this embodiment, the placement groove 1011 corresponds to the container mounting hole 102. When the first clamping member 401 and the second clamping member 402 are in the first position, the container is passed through the container mounting hole 102 and the bottom of the container is located in the placement groove 1011. When the first clamping member 401 and the second clamping member 402 are not clamping the container, the stability of the container is improved.

[0078] In one embodiment, the first perforation 5 and the second perforation 6 have the same diameter, and the diameter of the first perforation 5 is greater than or equal to the diameter of the container mounting hole 102.

[0079] In one embodiment, gaskets are provided on the inner walls of both the first perforation 5 and the second perforation 6.

[0080] In this embodiment, the gasket can protect the container, and the gasket can play a role in cushioning and fixing, preventing it from loosening or falling off the container due to vibration or impact, thereby improving stability.

[0081] In one embodiment, such as Figure 4As shown, the first clamping member 401 includes a first connecting rod 4011 and a first connecting plate 4012. One end of the first connecting rod 4011 is rotatably connected to the support member 2, and the other end is connected to the first connecting plate 4012. A first through hole 5 is provided on the first connecting plate 4012.

[0082] And / or, the second clamping member 402 includes a second connecting rod 4021 and a second connecting plate 4022. One end of the second connecting rod 4021 is rotatably connected to the support member 2, and the other end is connected to the second connecting plate 4022. A second through hole 6 is provided on the second connecting plate 4022.

[0083] The following is an example, combined with Figures 1 to 4 A comprehensive explanation of all the above-mentioned plans is provided.

[0084] When the sample feeding device is stationary, the first clamping member 401 and the second clamping member 402 are located in the first position. The first through hole 5, the second through hole 6 and the container mounting hole 102 are coaxially arranged. The diameters of the first through hole 5 and the second through hole 6 are the same. The diameter of the first through hole 5 is greater than or equal to the diameter of the container mounting hole 102, which facilitates the container to pass through the container mounting hole 102, the first through hole 5 and the second through hole 6, so that the container can be inserted into the placement groove 1011, thereby improving the stability of the container.

[0085] After the container is in place, the motor drives the screw 4041 to rotate, and the rotation of the screw 4041 causes the connecting block 4042 to move along the length of the screw 4041. When the connecting block 4042 moves away from the motor along the axial direction of the screw 4041, the first connecting rod 4043 and the second connecting rod 4044 push the first clamping member 401 and the second clamping member 402 to rotate in opposite directions, driving the first clamping member 401 and the second clamping member 402 to move from the first position to the second position. The central axes of the first through hole 5 and the second through hole 6 are misaligned, clamping the container in the container mounting hole 102.

[0086] The support column 7 can be connected to the drive device through a transmission component, which drives the support column 7 to rotate, thereby causing the connecting column to rotate at a preset angle, and then transporting the container to the sample detection position for detection.

[0087] After the sample in the container is tested, when the container needs to be removed from the container mounting hole 102, the motor reverses and drives the connecting block 4042 to move closer to the motor along the axial direction of the screw 4041. The first connecting rod 4043 and the second connecting rod 4044 pull the first clamping member 401 and the second clamping member 402 to rotate in opposite directions, driving the first clamping member 401 and the second clamping member 402 to move from the second position to the first position. The central axes of the first through hole 5 and the second through hole 6 are coaxial, releasing the container and removing it from the container mounting hole 102.

[0088] Both the first clamping member 401 and the second clamping member 402 have through holes at one end near the annular groove 201. The through holes are located on the first connecting rod 4011 and the second connecting rod 4021. The rotating connecting member is a pin. The pin passes through the through holes on the first connecting rod 4011 and the second connecting rod 4021. The pin is rotatably connected to the through holes. The two ends of the pin are respectively connected to the two side walls of the annular groove 201. The pin is parallel to the axis of the first through hole 5.
