Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a fully automatic chemiluminescence measuring instrument. Background Art

[0002] The reaction cup used in the fully automatic chemiluminescence analyzer is disposable, and the used reaction cup (i.e., waste cup) falls into the waste cup box from the waste cup outlet along the pipeline.

[0003] For example, in the patent with the publication number CN210285045U, a "waste cup storage device for a fully automatic chemiluminescence analyzer" is disclosed. Figure 1 The patent includes a discharge pipe and a waste cup box 7. The discharge pipe is provided with a waste cup inlet 4 for waste cups to enter and a waste cup outlet 5 for waste cups to be discharged. The waste cup outlet 5 extends into the interior of the waste cup box 7. Two guide rods 6 are symmetrically provided on the left and right sides of the waste cup box 7. The waste cup box 7 is slidably connected to the guide rods 6. A motor bracket is fixedly installed on one side of the guide rod 6. A stepper motor 1 is fixedly installed on the motor bracket. A gear 2 is fixedly installed on the output end of the stepper motor 1. A rack 3 is fixedly installed on the side of the waste cup box 7. The rack 3 and the gear 2 are engaged with each other.

[0004] The above patent can drive the gear 2 to rotate through the stepper motor 1, and the gear 2 drives the waste cup box 7 to slide back and forth on the guide rod 6 through the rack 3. The waste cup box 7 shakes during the movement, so that the waste cups accumulated in the waste cup box 7 are flattened, so that the waste cup box 7 can accommodate more waste cups.

[0005] Because the gear 2 at the output end of the stepper motor 1 is engaged with the rack 3 on the side of the waste cup box 7, after the stepper motor 1 is turned off, the stationary gear 2 prevents the rack 3 from disengaging from the gear 2. Therefore, the waste cup box 7 cannot be removed to dump the waste cups, which makes it inconvenient to clean the waste cup box 7. Utility Model Content

[0006] In view of the above-mentioned deficiencies in the prior art, the present invention provides a fully automatic chemiluminescence measuring instrument. The present invention can facilitate the cleaning of a waste cup box.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A fully automatic chemiluminescence analyzer includes a feed pipe and a waste cup box. The feed pipe is provided with a waste cup inlet for waste cups to enter and a waste cup outlet for waste cups to be discharged. The waste cup box includes a fixed box and a movable box. A rack is provided on the side of the fixed box, and an opening is provided on the side wall of the fixed box. The movable box slides horizontally in and out of the interior of the fixed box through the opening. The waste cup outlet is provided above the movable box. A locking mechanism is provided at one end of the movable box close to the opening. The locking mechanism is used to lock the movable box inside the fixed box.

[0009] Furthermore, the locking mechanism includes a rotating shaft, a pull ring, a pull rod, a connecting rod, and an insertion rod. The rotating shaft is rotatably connected to the side wall of the movable box. A pull ring is provided at one end of the rotating shaft outside the movable box, and two pull rods are symmetrically provided at one end of the rotating shaft inside the movable box. The pull rod is rotatably connected to the connecting rod at the end away from the rotating shaft, and the connecting rod is rotatably connected to the end away from the pull rod. The side wall of the movable box is provided with a first socket, and the side wall of the fixed box is provided with a second socket. The insertion rod is plugged into and cooperated with the first socket and the second socket in sequence.

[0010] Furthermore, the rotating shaft adopts a hollow shaft, the side wall of the rotating shaft is provided with a convex portion and a deformation hole, the side wall of the movable box is provided with a rotating hole, the rotating hole is rotatably matched with the rotating shaft, and the hole wall of the rotating hole is provided with at least two slots, which cooperate with the convex portion.

[0011] Furthermore, the rotating shaft is provided with a circular plate at one end away from the pull ring, the pull rod is provided on the outer periphery of the circular plate, the outer side wall of the rotating shaft is provided with a limiting portion, and the side wall of the movable box is provided between the limiting portion and the circular plate.

[0012] Furthermore, the inner wall of the movable box is provided with a guide groove, in which a partition is inserted. The partition divides the interior of the movable box into a waste cup collection chamber and an adjustment chamber. The adjustment chamber is provided with the pull rod, the connecting rod and the insertion rod.

[0013] Furthermore, a cover plate is bent on the top of the partition, and the cover plate is used to shield the adjustment cavity, and a hole is provided on the cover plate.

[0014] The utility model has the beneficial effects:

[0015] 1. In the present invention, the rack on the side of the fixed box can maintain a meshing state with the gear. When the locking state between the movable box and the fixed box is released, the movable box can be horizontally pulled out from the open mouth of the fixed box, and the waste cups contained in the movable box can be poured out, which is convenient for cleaning the waste cup box.

[0016] 2. Because the movable box can be locked with the fixed box through a locking mechanism, the movable box can be shaken back and forth together with the fixed box, so that the waste cups inside the movable box are shaken and flattened, so that the movable box can accommodate more waste cups.

[0017] 3. The method of pulling out the movable box horizontally can improve the stability of the movable box and reduce the chance of the waste cup falling out of the movable box, so as to facilitate the one-time cleaning of the waste cup.

[0018] 4. Simply rotate the shaft in the locking mechanism and the rod will exit the second socket, releasing the lock between the fixed and movable boxes. Simply rotate the shaft in the opposite direction to restore the lock. This makes operation simple and improves efficiency.

[0019] 5. By setting a partition, the interior of the movable box can be divided into a waste cup collection chamber and an adjustment chamber, which can prevent the waste cup from interfering with the movement of the pull rod and the connecting rod, and ensure the operational reliability of the locking mechanism.

[0020] 6. The setting of the cover plate can cooperate with the partition to fully block the adjustment cavity and improve the blocking effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Example:

[0045] See also Figures 10 to 12 , a fully automatic chemiluminescence measuring instrument, including a feeding pipe and a waste cup box 7.

[0046] See also Figures 10 to 12 The discharge pipe is provided with a waste cup inlet 4 for waste cups to enter and a waste cup outlet 5 for waste cups to be discharged.

[0047] See also Figure 2 and Figure 3 The waste cup box 7 includes a fixed box 71 and a movable box 72 .

[0048] See also Figure 2 and Figure 3 The rack 3 is fixedly mounted on the right side of the fixed box 71 , and an opening 711 is provided on the front side wall of the fixed box 71 .

[0049] See also Figure 2 and Figure 3The movable box 72 slides horizontally in and out of the fixed box 71 through the opening 711. The waste cup outlet 5 is located above the movable box 72 to prevent the waste cup outlet 5 from interfering with the horizontal withdrawal of the movable box 72 from the opening 711. A locking mechanism is provided at the front end of the movable box 72 to lock the movable box 72 inside the fixed box 71.

[0050] See also Figures 4 to 8 The locking mechanism includes a rotating shaft 81, a pull ring 82, a pull rod 83, a connecting rod 84, and an inserting rod 85.

[0051] See also Figure 9 The front side wall of the movable box 72 is provided with a rotation hole 721, and the hole wall of the rotation hole 721 is provided with two card slots, which are respectively marked as a first card slot 7211 and a second card slot 7212.

[0052] See also Figure 7 and Figure 8 The rotating shaft 81 adopts a hollow shaft, and a protrusion 811 is fixedly installed on the outer wall of the rotating shaft 81. The side wall of the rotating shaft 81 is also provided with a deformation hole 812, and the rotating shaft 81 rotates in conjunction with the rotating hole 721.

[0053] See also Figure 7 and Figure 8 A pull ring 82 is fixedly installed on the front end of the rotating shaft 81. The pull ring 82 is located on the outside of the movable box 72 and is used for being operated by the user.

[0054] See also Figure 7 and Figure 8 A circular plate 813 is fixedly installed on the rear end of the rotating shaft 81, and the circular plate 813 is located on the inner side of the movable box 72. A limiting portion 814 is fixedly installed on the outer wall of the rotating shaft 81. The limiting portion 814 and the circular plate 813 sandwich the front side wall of the movable box 72 in the middle, which can prevent the rotating shaft 81 from moving back and forth in the rotating hole 721, and can only allow the rotating shaft 81 to rotate in the rotating hole 721, thereby improving the reliability of the rotating shaft 81 during rotation.

[0055] See also Figure 7 and Figure 8 Two pull rods 83 are symmetrically provided on the outer periphery of the circular plate 813, and the pull rods 83 and the circular plate 813 are an integral structure. Figures 4 to 6 The pull rod 83 is rotatably connected to the connecting rod 84 at one end away from the rotating shaft 81, and the connecting rod 84 is rotatably connected to the insertion rod 85 at one end away from the pull rod 83. The side wall of the movable box 72 is provided with a first insertion hole 722. Figure 2 The side wall of the fixing box 71 is provided with a second insertion hole 712. The insertion rod 85 is plugged into and matched with the first insertion hole 722 and the second insertion hole 712 in sequence.

[0056] When rotating shaft 81, the operator must exert force to overcome the resistance of protrusion 811 from the first engaging groove 7211 or the second engaging groove 7212 in order to smoothly rotate shaft 81. During the rotation of shaft 81, deformation hole 812 can adaptively deform. When protrusion 811 is squeezed into the first engaging groove 7211 or the second engaging groove 7212, shaft 81 can be stabilized without external rotational force.

[0057] When the protrusion 811 is inserted into the second slot 7212, the rod 85 is inserted into the first and second holes 722 and 712, and the movable box 72 and the fixed box 71 are locked. When the protrusion 811 on the rotating shaft 81 is inserted into the first slot 7211, the rod 85 is withdrawn from the second hole 712, and the locking state between the movable box 72 and the fixed box 71 is released.

[0058] See also Figures 4 to 6 A guide groove 723 is fixedly mounted on the inner wall of the movable box 72. A partition 724 is inserted into the guide groove 723. The partition 724 divides the interior of the movable box 72 into a waste cup collection chamber and an adjustment chamber. The adjustment chamber is equipped with a pull rod 83, a connecting rod 84, and an insertion rod 85. This arrangement prevents waste cups from interfering with the movement of the pull rod 83 and connecting rod 84, ensuring the reliability of the locking mechanism.

[0059] See also Figure 2 and Figure 3 The top of the partition 724 is bent into a cover 7241, which is used to block the top of the adjustment cavity. The cover 7241 is provided with a cutout 7242. The provision of the cover 7241 can fully block the adjustment cavity, improving the shielding effect. When the partition 724 needs to be removed, the operator inserts a finger through the cutout 7242 to the bottom of the cover 7241, then lifts the cover 7241 upward with the finger. The cover 7241 and the partition 724 are pulled out together, completing the removal of the partition 724.

[0060] See also Figures 10 to 12 Two guide rods 6 are symmetrically arranged on the left and right sides of the fixed box 71. The guide rods 6 are fixedly installed inside the fully automatic chemiluminescence meter. The fixed box 71 is slidably connected to the guide rods 6 along the front and back directions. A motor bracket is fixedly installed on the right guide rod 6, and a stepper motor 1 is fixedly installed on the motor bracket. A gear 2 is fixedly installed on the output end of the stepper motor 1, and the gear 2 is engaged with the rack 3.

[0061] The working principle of collecting waste cups in this embodiment is as follows: the stepper motor 1 drives the gear 2 to rotate, and the gear 2 drives the fixed box 71 to slide back and forth along the guide rod 6 through the rack 3. Since the movable box 72 is fixed inside the fixed box 71 by a locking mechanism, the movable box 72 slides back and forth with the fixed box 71. The movable box 72 shakes during the back and forth movement, so that the waste cups accumulated in the movable box 72 are flattened, so that the movable box 72 can accommodate more waste cups.

[0062] See also Figures 10 to 12 In this embodiment, in order to control the rotation of the stepper motor 1, two tact switches 9 are symmetrically provided on the front and rear sides of the fixed box 71. The tact switches 9 can be mounted on the guide rod 6 or other mounting brackets. When the fixed box 71 moves forward and backward and contacts the tact switches 9, the stepper motor 1 changes direction, thereby driving the waste cup box 7 to move in the opposite direction. Figure 10 and Figure 11 The height of the touch switch 9 located on the front side of the fixed box 71 is lower than the bottom surface of the movable box 72, so that when the movable box 72 is pulled out horizontally, it will not be hindered by the touch switch 9.

[0063] The working principle of cleaning waste cups in this embodiment is as follows: the operator rotates the rotating shaft 81 through the pull ring 82, and the rotating shaft 81 drives the two pull rods 83 to rotate, and the pull rod 83 drives the insertion rod 85 to horizontally exit the second insertion hole 712 on the side wall of the fixed box 71 through the connecting rod 84, at this time, the locking state of the movable box 72 and the fixed box 71 is released; then, the operator pulls the movable box 72 horizontally out of the opening 711 of the fixed box 71 through the pull ring 82, and dumps the waste cups in the movable box 72; after that, the operator pushes the movable box 72 horizontally into the interior of the fixed box 71 from the opening 711; finally, the operator rotates the rotating shaft 81 in the opposite direction, and the rotating shaft 81 drives the two pull rods 83 to rotate in the opposite direction, and the pull rod 83 drives the insertion rod 85 to be reinserted into the second insertion hole 712 through the connecting rod 84, so that the movable box 72 is restored to the locking state with the fixed box 71.

[0064] From the above introduction, it can be seen that in this embodiment, the rack 3 on the side of the fixed box 71 can maintain an engagement state with the gear 2. When the locking state between the movable box 72 and the fixed box 71 is released, the movable box 72 can be horizontally pulled out from the opening 711 of the fixed box 71, and the waste cups contained in the movable box 72 can be poured out, which makes it convenient to clean the waste cup box 7.

[0065] Because the movable box 72 can be locked with the fixed box 71 through the locking mechanism, the movable box 72 can be rocked back and forth together with the fixed box 71, so that the waste cups inside the movable box 72 are rocked and flattened, so that the movable box 72 can accommodate more waste cups.

[0066] The method of horizontally pulling out the movable box 72 can improve the stability of the movable box 72 and reduce the probability of the waste cup falling out of the movable box 72, thereby facilitating the one-time cleaning of the waste cup.

[0067] By simply rotating the shaft 81 in the locking mechanism, the rod 85 can be withdrawn from the second insertion hole 712, thereby releasing the locking state between the fixed box 71 and the movable box 72; and by simply rotating the shaft 81 in the opposite direction, the locking state between the fixed box 71 and the movable box 72 can be restored. This is a simple operation that can improve operating efficiency.

[0068] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
