Description

Technical Field

[0001] This utility model relates to the field of automated in vitro diagnostic equipment technology, specifically to a feeding slide structure and a testing and analysis instrument. Background Technology

[0002] Chemiluminescence immunoassay analyzers are medical testing instruments that perform immunoassays on the human body by detecting patient serum. In chemiluminescence immunoassay analyzers, the feeding chute structure is the main structure for conveying reaction cups. The feeding chute structure also has the function of correcting and sorting the reaction cups. In existing technologies, the correction time for reaction cups in the feeding chute structure is generally long. For high-speed equipment, due to the short feeding interval from the hopper to the feeding chute, stacking and jamming of reaction cups occur in the feeding chute structure, failing to meet the feeding requirements of high-speed equipment and seriously affecting feeding efficiency. Utility Model Content

[0003] In view of this, the present invention provides a feeding slide structure and a testing and analysis instrument to solve the problems that conventional feeding slide structures have a long correction time for reaction cups, cannot meet the feeding requirements of high-speed equipment, and have the phenomena of cup stacking and cup jamming, which seriously affect the feeding efficiency.

[0015] Optionally, the guide includes:

[0016] A connecting plate is connected to the inner wall of the feed end;

[0017] A guide groove, connected to the connecting plate, extends obliquely at one end to protrude from the feed end, and the guide groove has a sliding surface that supports the reaction cup.

[0018] Optionally, a first baffle and a second baffle are respectively provided on two opposite outer sides of the slide. The tops of the first baffle and the second baffle are higher than the top surface of the slide and extend in the same direction as the slide. One end of the first baffle and the second baffle is connected to the discharge end.

[0019] The top plate is formed by bending the top of one of the first baffle and the second baffle and overlapping the top of the other baffle, or the extension direction of the top plate is the same as the extension direction of the first baffle and the second baffle, and the two ends of the top plate are respectively connected to the top of the first baffle and the second baffle.

[0020] Optionally, the paddle mechanism includes a rotating seat and a rotating shaft disposed on the top plate. The rotating seat is disposed on one of the top plate, the first baffle, and the second baffle, and the paddle is rotatably engaged with the rotating shaft.

[0021] The paddle has a natural state and a deflected state. In the natural state, the end of the paddle is located on the movement path of the reaction cup. In the deflected state, the paddle is moved away from the movement path of the reaction cup. The paddle is adapted to change from the natural state to the deflected state upon contact with the reaction cup; and / or,

[0022] The paddle has a bend at its end near the slide, and the bend bends toward the downstream direction of the slide.

[0023] Optionally, the two ends of the top plate are respectively configured as a first folded edge and a second folded edge.

[0024] Beneficial effects:

[0025] 1. The feeding chute structure provided by this utility model includes: a hopper, a chute, a receiving component, and a pusher cup structure.

[0026] The hopper has a feed end and a discharge end. The feed end is used to receive the reaction cups from the silo.

[0027] The chute is located at the discharge end and extends partially into the hopper. The reaction cup that enters the hopper will fall onto the chute and then leave the hopper from the discharge end along the chute.

[0028] The receiving component is located at the point where the chute extends into the hopper, specifically at the point where the reaction cups land after entering the hopper. During the feeding process, a large number of disordered reaction cups will fall into the hopper sequentially and collide with the receiving component. After impacting the receiving component, the reaction cups can quickly flip over and enter the chute. This design allows the receiving component to unify the landing position of the reaction cups, accelerates the speed at which the reaction cups adjust their position and slide down the chute, reduces the time the reaction cups spend in the hopper, and prevents subsequently falling reaction cups from contacting those adjusting their position on the chute, thus reducing the probability of cup stacking and jamming.

[0029] The cup-pulling structure includes a lever located above the slide. One end of the lever is rotatably positioned close to the discharge end, while the other end extends towards the slide. The lever is used to correct the posture of the reaction cup entering the slide. The lever can not only reduce the probability of the cup moving horizontally, but also slow down the movement speed of the reaction cup, thereby reducing the impact force of the reaction cup on the downstream reaction cup in the slide. It can effectively prevent failures caused by cup swiping and can efficiently handle the reaction cup.

[0030] Therefore, the feeding slide structure provided by this utility model improves the calibration efficiency of the reaction cup through the receiving component, reduces the time the reaction cup takes to pass through the drop hopper, can adapt to the feeding requirements of high-speed equipment for reaction cups, reduces the probability of cup stacking and cup jamming, and can also prevent malfunctions caused by cup rushing through the paddle.

[0031] 2. The feeding chute structure provided by this utility model has a groove for the reaction cup to slide in, and a receiving component is set in the groove. The receiving component includes an impact surface, which is inclined relative to the chute. The inclined impact surface can cover all landing points of the reaction cup and is suitable for receiving the reaction cup that is thrown obliquely. Specifically, after the reaction cup leaves the guide, it makes an oblique throwing motion, and the end of the reaction cup will hit the impact surface, so that the reaction cup can quickly flip and enter the chute, thereby improving the correction speed of the reaction cup.

[0032] 3. The feeding slide structure provided by this utility model includes a first part and a second part on the impact surface. The first part is located in the slide groove, and the second part extends to the top of the slide groove. Since the reaction cups enter the guide member in a disordered manner, the contact positions between the guide cups and the impact surface are different after the guide cups leave the guide member. When the landing point of the reaction cup is located in the first part, the reaction cup flips along the first direction after contacting the first part. When the landing point of the reaction cup is located in the second part, the reaction cup flips along the second direction opposite to the first direction after contacting the second part, thereby improving the correction speed.

[0033] 4. The feeding chute structure provided by this utility model includes a connecting part and an impact part. The connecting part is parallel to the extension direction of the chute and slides against the bottom of the chute. The connecting part is fixed in the chute by fasteners. The impact part extends from one end of the connecting part towards the opening of the chute, partially protruding from the chute, with the impact surface located on the impact part. The connecting part can improve installation stability, will not interfere with the movement of the reaction cup down the chute, and can be adjusted in position along the extension direction of the chute to adjust the position of the impact part, thereby adapting to the landing position of the reaction cup.

[0034] 5. The feeding chute structure provided by this utility model also includes a guide member, which is inclinedly disposed at the feeding end. The guide member is used to guide the reaction cups to impact the receiving member. The guide member can guide the reaction cups falling into the feeding end and guide them to impact the receiving member. This arrangement can further guide the landing position of the reaction cups to unify the landing position of the reaction cups. The guide member, together with the receiving member, can further accelerate the speed at which the reaction cups adjust their posture and slide down the chute, reduce the time the reaction cups stay in the hopper, and prevent subsequent falling reaction cups from contacting the reaction cups adjusting their posture on the chute, thereby reducing the probability of cup stacking and jamming.

[0035] 6. The feeding chute structure provided by this utility model includes a connecting plate and a guide groove as guide components. The connecting plate is connected to the inner wall of the feed end. The guide groove is connected to the connecting plate, with one end extending obliquely to the feed end. The guide groove has a sliding surface that supports the reaction cups. This arrangement facilitates adjustment of the position and angle of the guide groove and improves its installation stability. One end of the guide groove extending from the feed end can connect with the upstream conveying structure. The sliding surface serves as a structure supporting the sliding of the reaction cups, facilitating the stable sequential introduction of the reaction cups into the discharge hopper.

[0036] 7. The feeding chute structure provided by this utility model has a first baffle and a second baffle respectively provided on two opposite outer sides of the chute. The tops of the first baffle and the second baffle are higher than the top surface of the chute, and their extension direction is the same as that of the chute. One end of the first baffle and the second baffle is connected to the discharge end. The top plate is formed by bending the top of one of the first baffle and the second baffle and overlapping the top of the other, or the extension direction of the top plate is the same as that of the first baffle and the second baffle, and both ends of the top plate are respectively connected to the tops of the first baffle and the second baffle. The first baffle and the second baffle can act as a barrier, forming a channel for the reaction cup to pass through together with the top plate, preventing the reaction cup from falling out of the chute due to incorrect positioning or impact.

[0037] 8. The feeding slide structure provided by this utility model includes a rotating seat and a rotating shaft mounted on the top plate. The rotating seat is mounted on one of the top plate, the first baffle, and the second baffle. The paddle is rotatably engaged with the rotating shaft. The paddle has a natural state and a deflected state. In the natural state, the end of the paddle is located on the movement path of the reaction cup. In the deflected state, the paddle is away from the movement path of the reaction cup. The paddle is adapted to change from the natural state to the deflected state when it comes into contact with the reaction cup.

[0038] With the above structure, the reaction cup, during its movement, will collide with the lever in its natural state. The lever, subjected to the impact force, deflects away from the slide rail around its pivot axis, returning to a deflected state. After the reaction cup passes beneath the lever, the lever, relying on its own weight, deflects towards the slide rail around its pivot axis, returning to its natural state. During this process, the lever reduces the momentum of the reaction cup, slowing its movement and facilitating posture correction. Therefore, the lever not only reduces the probability of the cup tilting but also slows its movement, thereby reducing the impact force on the downstream reaction cups on the slide rail, effectively preventing malfunctions caused by cup tilting. Furthermore, this structure eliminates the need for a drive mechanism to propel the lever's swing; the lever, in conjunction with the pivot axis, utilizes its own weight as a power source to return from the deflected state to its natural state. The structure is simple and efficiently handles the reaction cup.

[0039] The paddle has a bend at its end near the slide, which curves downstream. Different reaction cups move at different speeds on the slide. Faster-moving reaction cups have a greater impact force, causing the paddle to deflect quickly upon impact. Slower-moving reaction cups have a smaller impact force, pushing the paddle to deflect and slide against its surface. After the paddle deflects to a certain extent, its end contacts the rim of the reaction cup until the cup leaves the paddle's position. The bend ensures that the surface of the paddle in contact with the rim of the reaction cup is curved, preventing the paddle end from obstructing the smooth passage of the reaction cup. The bend also increases the weight of the paddle end, facilitating self-realignment back to its natural position.

[0040] 9. The feeding chute structure provided by this utility model has a first folded edge and a second folded edge at both ends of the top plate. The first folded edge is close to the discharge end and bends away from the chute. The second folded edge extends out of the chute and bends towards the chute. The first folded edge can adjust the reaction cup in an incorrect position. After the reaction cup contacts the first folded edge, it quickly flips over. The second folded edge can buffer the reaction cup that leaves the chute. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0058] See Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of the feeding chute structure in this embodiment is shown. Figure 2 A schematic diagram of the receiving component 32 in this embodiment is shown, specifically illustrating the mating relationship between the guide component 31 and the receiving component 32, as well as the mating relationship between the receiving component 32 and the slide rail 2. Figure 3 A schematic diagram of the paddle structure is shown, specifically illustrating the installation position of paddle 4 and the cooperation relationship between paddle 4 and slide 2.

[0059] See Figure 1 and Figure 2 This embodiment provides a feeding slide structure, including: a hopper 1, a slide 2, a receiving component 32, and a cup structure.

[0060] The hopper 1 has a feed end 11 and a discharge end 12. The feed end 11 is used to receive the reaction cup 5 from the hopper. The hopper 1 is composed of multiple plates. The opening size of the feed end 11 of the hopper 1 is larger than the opening size of the discharge end 12. The inner wall of the hopper 1 near the slide 2 is inclined.

[0061] The slide 2 is located at the discharge end 12 and partially extends into the hopper 1. The reaction cup 5 entering the hopper 1 falls onto the slide 2 and then leaves the hopper 1 from the discharge end 12 along the slide 2. The slide 2 consists of two identical and parallel sliding plates with a gap between them, forming a chute for material movement. The reaction cup 5 has a tubular structure with a flat opening and an arc-shaped bottom. The outer wall of the reaction cup 5 is provided with lugs 51, which are positioned close to the opening. The distance between the two inner walls of the chute is greater than the diameter of the reaction cup 5 but less than the outer diameter of the lugs 51, allowing the reaction cup 5 to partially extend into the chute and slide. The lugs 51 can overlap the upper surface of the chute and slide. The slide 2 is inclined relative to the horizontal plane, allowing the reaction cup 5 to slide down the slide by its own weight. The end of the slide 2 that extends into the hopper 1 can fit against the inner wall of the hopper 1 opposite to the discharge end 12.

[0062] The receiving component 32 is located at the point where the slide 2 extends into the hopper 1, and at the point where the reaction cups 5 fall into the hopper 1. During the feeding process, a large number of disordered reaction cups 5 will fall into the hopper 1 in sequence and collide with the receiving component 32. After impacting the receiving component 32, the reaction cups 5 can quickly flip over and enter the slide 2. This arrangement can unify the landing position of the reaction cups 5 through the receiving component 32, and can speed up the adjustment speed of the reaction cups 5 and the speed of sliding down the slide 2, reduce the time that the reaction cups 5 stay in the hopper 1, and prevent the reaction cups 5 that fall later from contacting the reaction cups 5 that are adjusting their position on the slide 2, thereby reducing the probability of cup stacking and cup jamming.

[0063] The cup-pulling structure includes a lever 4 located above the slide 2. One end of the lever 4 is rotatably positioned close to the discharge end 12, and the other end extends toward the slide 2. The rotation path of the lever 4 is on the same plane as the slide groove of the slide 2. The lever 4 is used to correct the posture of the reaction cup entering the slide 2. The lever 4 can not only reduce the probability of the cup being horizontal, but also slow down the movement speed of the reaction cup 5, thereby reducing the impact force of the reaction cup 5 on the downstream reaction cup 5 of the slide 2. It can effectively prevent the failure caused by the cup being flushed, and can efficiently handle the reaction cup 5.

[0064] Therefore, the feeding slide structure provided by this utility model improves the calibration efficiency of the reaction cup 5 through the receiving part 32, reduces the time of the reaction cup 5 passing through the drop hopper 1, can adapt to the feeding requirements of high-speed equipment for the reaction cup 5, reduces the probability of cup stacking and cup jamming, and can also prevent malfunctions caused by cup rushing through the paddle 4.

[0065] In a preferred embodiment, the feeding chute structure further includes a guide member 31, which is inclinedly disposed at the feed end 11. A receiving member 32 is located at the landing point where the reaction cup 5 is guided by the guide member 31 to slide. There is a gap between the guide member 31 and the receiving member 32 that allows the reaction cup 5 to pass through. The guide member 31 is used to guide the reaction cup 5 to impact the receiving member 32. The guide member 31 can guide the reaction cup 5 falling into the feed end 11 and guide it to impact the receiving member 32. This arrangement can further guide the landing point of the reaction cup 5 to unify the landing point of the reaction cup 5. The guide member 31, together with the receiving member 32, can further accelerate the speed at which the reaction cup 5 adjusts its posture and slides down the chute 2, reduce the time the reaction cup 5 stays in the discharge hopper 1, and prevent the reaction cup 5 falling later from contacting the reaction cup 5 that is adjusting its posture on the chute 2, thereby reducing the probability of cup stacking and cup jamming.

[0066] In one optional embodiment, the guide member 31 can be disposed on the side near the discharge end 12. The guide member 31 is inclined downward from the side near the discharge end 12 to the side away from the discharge end 12. The receiving member 32 is located on the side away from the discharge end 12. The guide member 31 points towards the receiving member 32, so that while the reaction cup 5 accurately falls onto the receiving member 32, the portion of the slide 2 extending into the hopper 1 can be utilized to a great extent. The slide 2 located in the hopper 1 has sufficient distance to adjust the position of the reaction cup 5. See reference. Figure 2 In this embodiment, the slide 2 has a groove for the reaction cup 5 to slide in. The receiving member 32 is disposed in the groove and includes an impact surface 33. The impact surface 33 is inclined relative to the slide 2. The impact surface 33 can be inclined upward from the slide 2 towards the inner wall of the hopper 1. The angle between the impact surface 33 and the horizontal plane can be smaller than the angle between the upper surface of the slide 2 and the horizontal plane, so that the impact surface 33 guides the movement of the reaction cup 5, making the reaction cup 5 tend to slide down the groove quickly. The inclined impact surface 33 forms an impact area 301 with a certain area, which can cover all the landing points of the reaction cup 5 and is suitable for receiving the reaction cup 5 thrown obliquely. Specifically, after the reaction cup 5 leaves the guide member 31, it makes an oblique throwing motion. The end of the reaction cup 5 will hit the impact surface 33, so that the reaction cup 5 can quickly flip and enter the slide 2, thereby improving the correction speed of the reaction cup 5.

[0067] participate Figure 2In this embodiment, the impact surface 33 includes a first part 331 and a second part 332. The first part 331 is located in the groove, and the second part 332 extends above the groove. Since the reaction cup 5 enters the guide member 31 in a disordered manner, the contact position between the guide cup and the impact surface 33 after leaving the guide member 31 is different. When the landing point of the reaction cup 5 is located in the first part 331, the reaction cup 5 flips along the first direction after contacting the first part 331. When the landing point of the reaction cup 5 is located in the second part 332, the reaction cup 5 flips along the second direction opposite to the first direction after contacting the second part 332, thereby improving the correction speed.

[0068] When the reaction cup 5 enters the guide member 31 in the first orientation, that is... Figure 2 The reaction cup 5, with its opening close to the receiving member 32, is in a position where the lug 51 changes the sliding posture of the reaction cup 5 along the guide member 31. The end of the reaction cup 5 closest to the receiving member 32 moves out of the guide member 31 at a first exit height, meaning the opening of the reaction cup 5 moves out of the guide member 31 at the first height. Therefore, the opening of the reaction cup 5 will contact the second part 332. Since the contact between the opening of the reaction cup 5 and the surface of the second part 332 is approximately a surface-to-surface contact, the entire reaction cup 5 flips at a first angle. Figure 2 As shown, the reaction cup 5 is rotated counterclockwise, and the bottom of the reaction cup 5 quickly enters the groove of the slide 2 and slides down the groove quickly.

[0069] When the reaction cup 5 enters the guide member 31 in the second orientation, that is, when it is in contact with... Figure 2 Conversely, with the bottom of the reaction cup 5 near the receiving member 32, the lug 51 changes the sliding position of the reaction cup 5 along the guide member 31. The end of the reaction cup 5 near the receiving member 32 moves out of the guide member 31 at a second outlet height, meaning the bottom of the reaction cup 5 moves out of the guide member 31 at a second height. Therefore, the bottom of the reaction cup 5 will contact the first part 331. Since the bottom of the reaction cup 5 is curved, the contact with the surface of the first part 331 is approximately a point-to-surface contact, causing the entire reaction cup 5 to flip at a second angle opposite to the first angle. Figure 2 As shown, the reaction cup 5 is flipped clockwise, and the bottom slides down along the first part 331 to quickly enter the groove of the slide 2, and then slides down quickly along the groove.

[0070] Taking the above two reaction cup feeding scenarios as examples, the first part 331 and the second part 332 of the impact surface 33 can be applied to two typical feeding scenarios, and ensure that the reaction cup flips in the correct way to quickly correct its position and slide down the slide 2 quickly.

[0071] See Figure 2In this embodiment, the receiving component 32 includes a connecting portion 321 and an impact portion 322, which can be integrally formed. The connecting portion 321 is parallel to the extending direction of the slide 2 and slides against the bottom of the slide groove. The connecting portion 321 is fixed in the slide groove by fasteners. The impact portion 322 extends from one end of the connecting portion 321 towards the opening of the slide groove to partially protrude from the slide groove, and the impact surface 33 is located on the impact portion 322. The fasteners can be screws, and the position of the impact portion 322 can be adjusted by moving the connecting portion 321 according to the required position of the impact cup.

[0072] The connecting part 321 can improve installation stability, will not interfere with the movement of the reaction cup 5 sliding down the slide 2, and can be adjusted in position along the extension direction of the slide 2 so as to adjust the position of the impact part 322 and thus adapt to the landing position of the reaction cup 5.

[0073] The bottom edge of the connecting part 321 can be parallel to the bottom edge of the slide 2, and the two are located on the same plane, which facilitates maintaining the relative angle between the impact part 322 and the slide 2. (See reference) Figure 2 In this embodiment, the guide member 31 includes a connecting plate 311 and a guide groove 312. The connecting plate 311 is connected to the inner wall of the feed end 11, and the connecting plate 311 can be integrally formed with the guide groove 312. The guide groove 312 is connected to the connecting plate 311, and one end extends obliquely out of the feed end 11. This arrangement facilitates the adjustment of the position and angle of the guide groove 312, and improves the installation stability of the guide groove 312. One end of the guide groove 312 extending out of the feed end 11 can dock with the upstream conveying structure, facilitating the stable introduction of the reaction cup 5 into the discharge hopper 1.

[0074] In one specific embodiment of this invention, the guide groove 312 has a sliding surface supporting the reaction cup 5, and a first stop surface and a second stop surface located on both sides of the sliding surface. The sliding surface serves as the main component supporting the sliding of the reaction cup 5, and the blocking action of the first and second stop surfaces can correct the movement direction of the reaction cup 5 on the sliding surface. The sliding surface, the first stop surface, and the second stop surface are all planar, and friction can be reduced on their surfaces through a polishing process, or a coating that reduces friction can be applied. The coating can be a Teflon coating, a carbon nanotube coating, etc., thereby further shortening the time it takes for the reaction cup 5 to pass through the guide member 31.

[0075] See Figure 1 , Figure 2 and Figure 3In this embodiment, a first baffle 601 and a second baffle 602 are respectively provided on two opposite outer sides of the slide 2. The tops of the first baffle 601 and the second baffle 602 are higher than the top surface of the slide 2, and their extension directions are the same as the extension direction of the slide 2. One end of the first baffle 601 and the second baffle 602 is connected to the discharge end 12. The top plate 603 is formed by bending the top of one of the first baffle 601 and the second baffle 602 and overlapping the top of the other. Alternatively, the extension direction of the top plate 603 is the same as the extension direction of the first baffle 601 and the second baffle 602, and both ends of the top plate 603 are respectively connected to the tops of the first baffle 601 and the second baffle 602.

[0076] The first baffle 601 and the second baffle 602 can act as a barrier, forming a channel for the reaction cup 5 to pass through together with the top plate 603, preventing the reaction cup 5 from falling off the slide 2 due to incorrect positioning or impact.

[0077] In a preferred embodiment, the throttle structure includes a rotating base 401 and a rotating shaft 402. The throttle 4 is rotatably engaged with the rotating shaft 402. The rotating base 401 is disposed on one of the top plate 603, the first baffle 601, and the second baffle 602. The throttle 4 has a natural state and a deflected state. In the natural state, the end of the throttle 4 is located on the movement path of the reaction cup 5. In the deflected state, the throttle 4 is away from the movement path of the reaction cup 5. The throttle 4 is adapted to change from the natural state to the deflected state when it comes into contact with the reaction cup 5. The natural state refers to the stationary state in which the throttle 4 remains engaged with the slide by its own weight, that is, the end of the throttle 4 is located on the movement path of the reaction cup 5. The deflected state refers to the movement state in which the throttle 4 deviates from the slide after being hit by the reaction cup 5. The throttle 4 can rotate from the deflected state back to the natural state by its own weight.

[0078] Through the above structure, during the movement of the reaction cup 5, it will collide with the paddle 4 in its natural state. The paddle 4, subjected to the impact force, deflects away from the slide 2 around the pivot 402, returning to its deflected state. After the reaction cup 5 passes under the paddle 4, the paddle 4, relying on its own weight, deflects towards the slide 2 around the pivot 402, returning to its natural state. During this process, the paddle 4 can reduce the momentum of the reaction cup 5, slowing down its movement speed and facilitating posture correction. Therefore, the paddle 4 not only reduces the probability of the cup tilting but also slows down the movement speed of the reaction cup 5, thereby reducing the impact force of the reaction cup on the downstream reaction cup 5 on the slide, effectively preventing malfunctions caused by cup tilting. Furthermore, this structure eliminates the need for a drive mechanism to propel the paddle 4. The paddle 4, in conjunction with the pivot 402, can utilize its own weight as a power source to return from its deflected state to its natural state. The structure is simple and can efficiently handle the reaction cup.

[0079] It should be noted that when the rotating seat 401 is set on the top plate 603, or when the rotation path of the paddle 4 passes through the top plate 603, the top plate 603 needs to have a corresponding notch 403. The notch 403 allows the paddle 4 to pass through, and the setting of the notch 403 can avoid interfering with the movement of the paddle 4.

[0080] In one optional embodiment, the end of the paddle 4 near the slide 2 has a bend 41, which bends towards the downstream direction of the slide 2. Different reaction cups 5 move at different speeds on the slide 2. The faster-moving reaction cups 5 have a greater impact force, which can cause the paddle 4 to deflect quickly through impact. The slower-moving reaction cups 5 have a smaller impact force, which will push the paddle 4 to deflect and slide against the surface of the paddle 4. After the paddle 4 deflects to a certain extent, the end of the paddle 4 will contact the mouth of the reaction cup 5 until the reaction cup 5 leaves the position of the paddle 4. The bend 41 makes the surface of the paddle 4 in contact with the mouth of the reaction cup 5 a curved surface, preventing the end of the paddle 4 from obstructing the smooth passage of the reaction cup 5. At the same time, the bend 41 can increase the weight of the end of the paddle 4 to a certain extent, making it easier for the paddle 4 to return to its natural state by self-realignment.

[0081] See Figure 3 and Figure 4 In this embodiment, the rotating seat 401 can be a plate-like structure. The rotating seat 401 is vertically mounted on the top plate 603. The extension direction of the rotating seat 401 is the same as the extension direction of the slide 2. The rotating shaft 402 can be mounted on the rotating seat 401 by a pin or fastening bolt. The rotating shaft 402 is located above the slide 2, and its rotation axis is perpendicular to the extension direction of the slide 2. The paddle 4 is a strip-shaped plate-like structure. One end of it is a rotating sleeve fitted onto the rotating shaft 402, and the other end is bent away from the discharge end 12. Figure 3 Taking the angle as an example, when the reaction cup 5 collides with the lever 4, the lever 4 deflects counterclockwise and moves away from the slide 2, so that there is a gap between the end of the lever 4 near the slide 2 and the upper surface of the slide 2 that allows the reaction cup in the correct position to pass through. After the reaction cup passes through, the lever 4 returns to its natural state by its own weight.

[0082] Figure 3 The scene shows the reaction cup 5 sliding down the slide 2 in a horizontal position. After the paddle 4 blocks the reaction cup 5, the reaction cup 5 is deflected to the bottom by the paddle force and extends into the groove of the slide 2. Then it slides down in the correct position, thereby avoiding the failure caused by the cup overflow.

[0083] See Figure 3The top plate 603 has a first folded edge 604 and a second folded edge 605 at its two ends. The first folded edge 604 is close to the discharge end 12 and bends away from the slide 2. The second folded edge 605 extends out of the slide 2 and bends towards the slide 2. The first folded edge 604 can adjust the reaction cup 5 if it is in the wrong position. After the reaction cup 5 comes into contact with the first folded edge 604, it flips quickly. The second folded edge 605 can buffer the reaction cup 5 as it leaves the slide 2.

[0084] To further improve the speed at which the paddle 4 returns to its natural state from the deflected state, a ball bearing can be provided on the rotating shaft 402. The paddle 4 can be fixed to the outer ring of the bearing by a rotating sleeve, and the inner ring of the bearing can be fixed to the rotating shaft 402.

[0085] See Figure 3 The discharge hopper 1 is equipped with a first detection optocoupler 13, which is located above the receiving part 32. The first detection optocoupler 13 is used to detect whether a cup jamming or blockage occurs in the discharge hopper 1, so as to ensure that the reaction cup detection is carried out smoothly.

[0086] See Figure 1 The slide 2 is equipped with a second detection optocoupler 7, which can be used to detect whether there is a certain number of reaction cups 5 on the slide 2, so as to adjust the cup feeding amount.

[0087] This utility model also provides a testing analyzer, including the aforementioned feeding chute structure. The testing analyzer includes, but is not limited to, a hopper, a conveying structure, and a sorting structure. The hopper can be located upstream of the feeding chute structure, and the sorting structure can be located downstream of the feeding chute structure. The chute 2 can be mounted on the frame of the testing analyzer via a bracket 8, or it can be mounted on the transfer tray structure of the testing analyzer, facilitating the docking of the chute 2 with the transfer tray structure. The structure, composition, connection methods of each component, and specific working process of the feeding chute structure have been described in detail above. Those skilled in the art can clearly understand the specific implementation method of the feeding chute structure of this embodiment based on the above description, and will not be repeated here.
