[0036] Figure 1 It is a schematic diagram of the overall structure of the sampling device provided for the embodiments of the present invention.

[0037] As Figure 1 shown, the sampling device provided by the present invention includes a frame 1, a first bracket 2, a puncture needle 3, and a bottle bin 4; the bottle bin 4 is arranged on the side of the frame 1 and is used to place a reagent bottle 5; the first bracket 2 is slidably arranged on the frame 1 so that the first bracket 2 can reciprocate along a first direction S1; one end of the puncture needle 3 is connected to the first bracket 2, and the other end of the puncture needle 3 is a puncture end, and the puncture end extends along the first direction S1; the puncture needle 3 can move along the first direction S1 following the first bracket 2 so that the puncture end can penetrate into the reagent bottle 5.

[0038] Compared with the prior art, the sampling device provided by the present invention has the following advantages:

[0039] The sampling device provided by the present invention slidably arranges the puncture needle 3 on the frame body 1 through the first bracket 2, and the bottle bin 4 is also arranged on the frame body 1. When sampling is required, the first bracket 2 slides on the frame body 1 along the first direction S1, so as to drive the puncture needle 3 to move towards the direction close to the bottle bin 4, and then perform sampling operation on the reagent bottle 5.

[0040] When all the trigger liquid contained in the reagent bottle 5 is collected, the sampling work of the reagent bottle 5 ends. Move the first bracket 2 in the direction away from the bottle bin 4, so as to drive the puncture needle 3 to disengage from the reagent bottle 5 and complete the sampling.

[0041] Since the puncture needle 3 and the bottle bin 4 in this application are both connected to the frame body 1, therefore, the bottle bin 4 and the puncture needle 3 can form an integral body, thus solving to a certain extent the technical problem that the structural parts of the existing puncture needle 3 mechanism are scattered and inconvenient for assembly and maintenance. And, since the puncture needle 3 in this application can reciprocate along the first direction S1 following the first bracket 2, therefore, the puncture needle 3 can perform puncture sampling operation on the reagent bottle 5 with the same puncture trajectory, thus solving to a certain extent the technical problem that the puncture process of the existing puncture needle mechanism needs to be carried out manually and the puncture trajectory cannot be precisely controlled, resulting in the puncture of the reagent bottle 5.

[0042] Preferably in this application, a receiving groove is opened on the bottle bin 4 along the first direction S1, and the reagent bottle 5 can be inserted into the receiving groove, and the receiving groove can play a role in limiting and protecting the reagent bottle 5.

[0043] It should be supplemented and explained here that the reciprocating movement of the first bracket 2 along the first direction S1 in this application can be realized by the dragging action of the operator, or can be realized by adding a power device such as a motor, a hydraulic cylinder and other structures to realize the automatic reciprocating movement of the first bracket 2 along the first direction S1.

[0044] Figure 2 It is the overall structural schematic diagram of the frame body 1 in the sampling device provided by the embodiment of the present invention.

[0045] Among them, as Figure 1 Combined Figure 2 shown, the frame body 1 is provided with a slide rail 101 along the first direction S1, the first bracket 2 is provided with a slider 201, and the first bracket 2 is slidably connected to the frame body 1 through the slider 201; a limiting member 102 is provided at one end of the frame body 1 away from the bottle bin 4, and the limiting member 102 can be engaged with the first bracket 2 so that the first bracket 2 can stop at the first position.

[0046] On one side of the first bracket 2 in this application facing the slide rail 101, a limit hole is provided corresponding to the position of the limiting member 102. The limiting member 102 can be inserted into the limit hole of the first bracket 2, so that the first bracket 2 stops at the first position. In this application, through the cooperation of the slide rail 101 and the slider 201, the first bracket 2 can be simply and quickly reciprocated along the first direction S1 on the frame 1.

[0047] During sampling, the first bracket 2 is moved towards the bottle bin 4, so that the puncturing end of the puncturing needle 3 pierces into the reagent bottle 5 for sampling. When one sampling is completed, first, the first bracket 2 is moved away from the bottle bin 4, and the limiting member 102 is inserted into the limit hole of the first bracket 2, so that the first bracket 2 can stop at the first position. Then, the reagent bottle 5 is taken out of the bottle bin 4. After replacing the reagent bottle 5 containing a new sample, the first bracket 2 is moved towards the bottle bin 4 again, and the puncturing needle 3 pierces into the reagent bottle 5 to complete the sampling.

[0048] By inserting the limiting member 102 into the limit hole of the slider 201, to a certain extent, it can avoid the problem that after sampling is completed, the first bracket 2 drops under the influence of gravity, resulting in damage to the puncturing needle 3 or even causing harm to the operator.

[0049] It should be noted here that in this application, a slider limiting member 103 is further provided on the frame 1, and a slider limit hole is provided at the position of the slider 201 corresponding to the slider limiting member 103. The setting of the slider limiting member 103 can prevent the slider 201 from moving along the slide rail 101 and sliding out of the slide rail 101 when the first bracket 2 moves upward, resulting in the separation of the first bracket 2 from the frame 1.

[0050] In this application, both the limiting member 102 and the slider limiting member 103 are preferably ball head plungers. The first bracket 2 can compress the ball head and retract it into the plunger. When it moves to the position of the limit hole, the ball head pops out and is inserted into the limit hole to realize the stop of the first bracket 2 at the first position. When the slider 201 moves to the slider limit hole, the ball head pops out and is inserted into the slider limit hole to prevent the slider 201 from sliding out of the slide rail 101.

[0051] Figure 3 It is a schematic diagram of the overall structure of the second perspective of the bottle bin 4 in the sampling device provided by the embodiment of the present invention; Figure 4 It is a schematic diagram of the overall structure of the first perspective of the bottle bin 4 in the sampling device provided by the embodiment of the present invention.

[0052] Specifically, as Figures 1 - 4 shown, a limit groove 401 is provided on one side of the bottle bin 4 close to the frame 1 along the first direction S1, and a limit portion 202 is provided on the first bracket 2 along the first direction S1; the limit portion 202 can abut against the bottom wall of the limit groove 401, so that the first bracket 2 can stop at the second position.

[0053] When sampling, the first bracket 2 is moved towards the bottle bin 4. When the limiting part 202 abuts against the bottom wall of the limiting groove 401, the puncturing end of the puncturing needle 3 pierces into the reagent bottle 5, and the first bracket 2 stops at the second position, thus avoiding the problem that the puncturing needle 3 continues to move towards the bottom of the reagent bottle 5 and piercing through the reagent bottle 5.

[0054] In the present application, the limiting part 202 can play a role in limiting the puncturing needle 3 during the sampling operation. Moreover, by abutting the limiting part 202 against the bottom wall of the limiting groove 401, the puncturing position of the puncturing needle 3 can also be fed back to the operator in real time, reducing the operation difficulty.

[0055] Among them, as Figures 1 - 4 shown, the sampling device provided by the present invention has a rotating shaft 9 provided on the frame body 1 along the second direction S2. The bottle bin 4 is rotatably connected to the rotating shaft 9, and the bottle bin 4 can rotate around the rotating shaft 9.

[0056] A damper 10 is further provided on the rotating shaft 9. The damper 10 is sleeved on the rotating shaft 9 and is connected to the bottle bin 4.

[0057] By rotatably connecting the bottle bin 4 to the damper 10 sleeved on the rotating shaft 9, the bottle bin 4 can rotate with the rotating shaft 9 as the rotation center. When the reagent bottle 5 needs to be replaced, the bottle bin 4 is rotated to open it, and the reagent bottle 5 is replaced. After the reagent bottle 5 is replaced, the bottle bin 4 is rotated again so that the axis of the bottle bin 4 is collinear with the puncturing needle 3, and the replacement of the reagent bottle 5 is completed.

[0058] Moreover, in the present application, by adding the damper 10 on the rotating shaft 9, the vibration generated during the opening and closing processes of the bottle bin 4 can be reduced to a certain extent, thereby improving the stability of the reagent bottle 5 in the bottle bin 4. Preferably, the damper 10 is a roller damper in the present application.

[0059] It should be supplemented and explained here that a fixing plate 8 is also provided in the present application. The fixing plate 8 is connected to the frame body 1 in an L shape. The fixing plate 8 is arranged parallel to the horizontal plane and is used to fix the frame body 1 on the installation table. And the frame body 1 can be made more stable by connecting the fixing plate 8 to the frame body 1 in an L shape. Multiple connection holes can be opened on the fixing plate 8 for installing the fixing plate 8.

[0060] Specifically, as Figures 1 - 4 shown, a receiving hole is opened at the bottom of the bottle bin 4 along the second direction S2. The rotating shaft 9 and the damper 10 are arranged in the receiving hole, so that the bottle bin 4 can rotate relative to the frame body 1; a backing plate 402 is provided on the bottle bin 4. The backing plate 402 extends along the second direction S2 and is located at the edge of the bottle bin 4 and on both sides of the receiving hole with respect to the axis of the bottle bin 4, so that the bottle bin 4 can rotate and open by relying on its own gravity with the rotating shaft 9 as the rotation center.

[0061] In the present application, the receiving hole and the back plate 402 are located on both sides of the axis of the bottle bin 4. The receiving hole is located at the bottom of the bottle bin 4, the back plate 402 extends along the second direction S2 and is located at the edge of the bottle bin 4, and the receiving hole and the back plate 402 are arranged diagonally.

[0062] The back plate 402 can increase the self-weight of the bottle bin 4. When the bottle bin 4 is opened, since the rotating shaft 9 is located at the bottom side of the bottle bin 4 and is arranged diagonally with the back plate 402, therefore, the bottle bin 4 can be rotated and opened by relying on its own gravity.

[0063] Furthermore, as Figures 1 - 4 shown, a stop portion 403 is provided on the side of the bottle bin 4 away from the back plate 402 and close to the frame body 1. When the first bracket 2 stops at the first position, the limiting portion 202 can abut against the stop portion 403.

[0064] Since the limiting member 102 in the present application adopts a ball head plunger, therefore, to avoid the danger caused by the first bracket 2 falling due to excessive force applied by the operator, by providing the stop portion 403 on the bottle bin 4, when the bottle bin 4 is in the open state, through the limitation of the first bracket 2 by the limiting member 102 and the limiting portion 202 on the first bracket 2 abutting against the stop portion 403, it can be further ensured that when the bottle bin 4 is in the open state, the first bracket 2 always stops at the first position, thereby effectively improving the overall use safety of the device.

[0065] When the bottle bin 4 rotates and closes, the stop portion 403 can move along with the bottle bin 4, so as to separate from the limiting portion 202, enabling the operator to move the first bracket 2 in the direction close to the bottle bin 4.

[0066] It should be supplemented and explained here that since the bottle bin 4 in the present application rotates or closes with the rotating shaft 9 as the rotation center, therefore, preferably in the present application, the stop portion 403 is fan-shaped and protrudes from the bottle bin 4, and the arc surface of the fan-shaped stop portion 403 abuts against the limiting portion 202.

[0067] Among them, as Figures 1 - 4 shown, the sampling device provided by the present invention further includes a second bracket 11 and a baffle 12; the baffle 12 is arranged along the third direction S3, and one end of the baffle 12 is connected to the second bracket 11, and the other end can contact the reagent bottle 5 for limiting the reagent bottle 5.

[0068] In the present application, by arranging the baffle 12 on the second bracket 11 along the third direction S3, when the sampling operation is completed and the puncture needle 3 is pulled out of the reagent bottle 5, through the limitation of the reagent bottle 5 by the baffle 12, to a certain extent, the problem that the puncture needle 3 takes the reagent bottle 5 away from the bottle bin 4 during the pulling-out process is avoided.

[0069] Specifically, as Figures 1 - 4As shown, a clamping groove 13 is provided on the second support 11, and a snap 404 is provided at the position of the bottle bin 4 corresponding to the clamping groove 13; when the first support 2 stays at the first position, the clamping groove 13 is separated from the snap 404, and when the snap 404 is engaged with the clamping groove 13, the first support 2 can reciprocate along the first direction S1.

[0070] When the first support 2 stays at the first position, the bottle bin 4 is in an open state, the clamping groove 13 is separated from the snap 404, and when the clamping groove 13 is engaged with the snap 404, the bottle bin 4 is in a closed state. At this time, the first support 2 can move towards the direction of the bottle bin 4, thereby driving the puncture needle 3 to perform a sampling operation.

[0071] Preferably in this application, the clamping groove 13 and the snap 404 adopt a push - type snap 404. When it is necessary to open the bottle bin 4, press the back plate 402 or the bottle bin 4, and the clamping groove 13 will eject the snap 404, and the bottle bin 4 rotates to open. Press the back plate 402 or the bottle bin 4 again, and the snap 404 is snapped into the clamping groove 13, so that the bottle bin 4 can be engaged. The push - type snap 404 can conveniently and quickly realize the rotational opening or closing of the bottle bin 4, and has a low cost, and is convenient for replacement and maintenance.

[0072] Furthermore, as Figures 1 - 4 shown, a needle base 14, an elastic member 6 and a channel - shaped member 7 are further provided on the first support 2, and the opening direction of the channel - shaped member 7 is towards the reagent bottle 5. The needle base 14 is arranged in the channel - shaped member 7, the puncture needle 3 passes through the first support 2 and is connected to the needle base 14, and the elastic member 6 is located between the needle base 14 and the channel - shaped member 7.

[0073] Preferably, the elastic member 6 in this application adopts a spring, and the spring can play a buffering role in the process of the puncture needle 3 piercing into the reagent bottle 5, making the piercing process more stable.

[0074] The puncture needle 3 is connected to the first support 2 through the needle base 14, which can increase the contact area between the puncture needle 3 and the first support 2, making the puncture process more stable. The needle base 14 is arranged in the channel - shaped member 7, one end of the elastic member 6 is connected to the needle base 14, and the other end abuts against the inner wall of the channel - shaped member 7. By connecting the elastic member 6 to the needle base 14, on the one hand, the buffering process of the elastic member 6 is more stable, and on the other hand, the piercing process of the puncture needle 3 is also more stable.

[0075] It should be supplemented and explained here that the first support 2 and the frame body 1 in this application are detachably connected; the puncture needle 3 and the needle base 14 are detachably connected, the needle base 14, the channel - shaped member 7 and the first support 2 are detachably connected; the bottle bin 4 and the frame body 1 are detachably connected; the third support and the frame body 1 are detachably connected. Through the detachable connection of each part of the structure, it is more convenient to repair the sampling device provided in this application and replace each part of the structure, so that the service life of the overall device is longer.

[0076] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
