DETAILED DESCRIPTION
[0027] The present invention will be further described below with reference to the accompanying drawings.
[0028] like Figures 1 to 4As shown, a preferred embodiment of a medical test reagent mixing processor of the present invention includes a shell 1, a cover plate 2, a accommodating mechanism, a drive shaft 31 and a driver 3. The driver 3 is installed in the shell 1, and the driver 3 is used to provide power. The driver 3 usually adopts a motor. The output shaft of the driver 3 is connected to the drive shaft 31, and the driver 3 is used to drive the drive shaft 31 to rotate. The drive shaft 31 is connected to the accommodating mechanism, and the drive shaft 31 drives the accommodating mechanism to rotate. The reagent tube is placed in the accommodating mechanism, and the accommodating mechanism is used to drive the reagent tube to rotate to mix the reagent; the accommodating mechanism can change the reagent tube to an inclined state to improve the mixing effect when the accommodating mechanism rotates, so that the reagents in the reagent tube are mixed more evenly. The cover plate 2 is rotatably installed on the shell 1, and is usually connected by a bearing connection method. The movable cover is used to close the accommodating mechanism and can also limit the tilt angle of the reagent tube.
[0029] Combine Figure 5 For reference, the accommodating mechanism includes an accommodating disc 4, an inner support ring 41, an accommodating tube 5, a fixing seat 6, an adjustment assembly 8, and a pressing assembly 7. The fixing seat 6 is mounted on the accommodating disc 4. The lower end of the accommodating tube 5 is connected to the fixing seat 6. The fixing seat 6 is used to position the lower end of the accommodating tube 5. The accommodating tube 5 can deflect with the fixing seat 6 as the base point. The inner support ring 41 is mounted on the accommodating disc 4. The adjustment assembly 8 is slidably mounted on the accommodating disc 4 and the inner support ring 41, so that the adjustment assembly 8 has stable support. The adjustment assembly 8 is connected to the accommodating tube 5. The adjustment assembly 8 drives the accommodating tube 5 to deflect with the fixing seat 6 as the base point. The pressing assembly 7 is mounted on the cover plate 2. The pressing assembly 7 is used to work in conjunction with the adjustment assembly 8 to change the position of the adjustment assembly 8. The receiving tube 5, fixing seat 6, and adjusting assembly 8 are all multiple, with each receiving tube 5 corresponding to a fixing seat 6 and adjusting assembly 8. The pressing assembly 7 is simultaneously linked with all adjusting assemblies 8 to allow all adjusting assemblies 8 to move toward or away from the center of the receiving tray 4. When placing the reagent tube, the receiving tube 5 is in a vertical position. Before mixing begins, the pressing assembly 7 is pressed. The pressing assembly 7 and the adjusting assembly 8 move away from the center of the receiving tray 4. The adjusting assembly 8 drives the receiving tube 5 in a direction away from the center of the receiving tray 4, causing the receiving tube 5 to tilt. This also tilts the reagent tubes, so that the upper and lower layers of the reagents are mixed evenly during the rotation process. After mixing is completed, the pressing assembly 7 is pressed again. The pressing assembly 7 automatically resets. Since the reset of the pressing assembly 7 provides space for the adjusting assembly 8 to reset, the adjusting assembly 8 also automatically resets, and the receiving tube 5 is reset to a vertical position; this makes it easier to remove the reagent tube from the receiving tube 5 and also easier to insert the reagent tube into the receiving tube 5 next time.
[0030] like Figure 6 As shown, the accommodating plate 4 has an outer support ring 42, one end of the adjusting assembly 8 is slidably mounted on the outer support ring 42, and the other end of the adjusting assembly 8 is slidably mounted on the inner support ring 41, thereby supporting the tilting sliding assembly. To facilitate the installation of the adjusting assembly 8, the outer support ring 42 includes a ring pressure cover 421 and a ring body 422. The ring pressure cover 421 is detachably fixed to the ring body 422, and the ring pressure cover 421 is usually fixed to the ring body 422 with screws. In this way, one end of the adjusting assembly 8 can be inserted into the inner support ring 41 first, and the other end of the adjusting assembly 8 is placed on the ring body 422. Then, the ring pressure cover 421 is fixed to the ring body 422, so that the adjusting assembly 8 cannot be separated from the outer support ring 42.
[0031] The pressing assembly 7 includes a pressing member 71, a movable guide member 72, a limiting block 73, a magnetic push block 74, and a first return spring 75. The pressing member 71 is inserted into the cover plate 2, with its upper end located above the cover plate 2 and its lower end located below the cover plate 2. The pressing member 71 is used to limit the adjustment assembly 8. When the adjustment assembly 8 abuts against the pressing member 71, the accommodating tube 5 is in a vertical position. The first return spring 75 is sleeved on the pressing member 71 and abuts against the pressing member 71 and the cover plate 2. The first return spring 75 is used to reset the pressing member 71. The limit block 73 is fixed to the lower end of the pressing member 71. The limit block 73 is integrated with the pressing member 71. In other embodiments, the limit block 73 can also be connected and fixed by welding or other means. The limit block 73 is used to limit the position of the adjustment component 8. When the adjustment component 8 contacts the limit block 73, the adjustment component 8 drives the accommodating tube 5 to tilt. The width of the limit block 73 is greater than the width of the pressing member 71, so that the position of the tilting and rotating component can be changed, and then the state of the accommodating tube 5 can be changed. When the adjustment component 8 contacts the pressing member 71, the adjustment component 8 also contacts the limit block 73 to limit the reset of the pressing member 71. The movable guide member 72 is sleeved on the lower end of the pressing member 71. The movable guide member 72 is located above the limit block 73. The movable guide member 72 is used to guide the movement of the adjustment component 8. The magnetic push block 74 is fixed on the pressing member 71 and moves synchronously with the pressing member 71. The magnetic push block 74 is located above the movable guide member 72. The magnetic push block 74 is used to reset the movable guide member 72, that is, to adsorb the movable guide member 72 on itself, and move synchronously with the magnetic push block 74 when there is no external force. It should be known that the movable guide member 72 is made of iron, which is convenient for cooperating with the magnetic push block 74.
[0032] When the lever 72 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the locking cam 73 is unlocked and the winch 73 is unlocked. After the pressing member 71 is released, the first return spring 75 causes the pressing member 71 to return to its original position and drive the limit block 73 and the magnetic push block 74 to return to their original position, i.e., move upward. Since the adjustment assembly 8 is now abutting against the movable guide member 72, the movable guide member 72 remains stationary until the movable guide member 72 and the limit block 73 are engaged. The pressing member 71 then continues to move upward, and the movable guide member 72 moves upward under the push of the limit block 73, causing the adjustment assembly 8 to abut against the limit block 73. In other words, the adjustment assembly 8 is passively slid from the movable guide member 72 to the limit block 73. When the adjustment assembly 8 slides to the limit block 73, the movable guide member 72 is returned to its original position under the suction force of the magnetic push block 74, thus guiding the adjustment assembly 8 downward. Due to the wide width of the press rod 711 of the limit block 73, the adjustment assembly 8 is able to move away from the receiving tray 4, thereby tilting the receiving tube 5. When it is necessary to reset the accommodating tube 5, that is, to change the accommodating tube 5 from an inclined state to a vertical state, lightly press the pressing piece 71 to move the limit block 73 upward, align the pressing piece 71 between the movable guide 72 and the limit block 73 with the adjustment component 8, and the adjustment component 8 automatically resets and rests on the pressing piece 71, driving the accommodating tube 5 to reset to a vertical state.
[0033] The pressing member 71 includes a pressing rod 711 and a pressing cap 712 . The pressing cap 712 is screwed onto the pressing rod 711 to facilitate installation of the pressing member 71 on the cover plate 2 .
[0034] like Figure 7As shown, the movable guide member 72 has a first guide slope 721 and a positioning slope 722. The lower end of the first guide slope 721 is closer to the center of the accommodating tray 4 than the upper end of the first guide slope 721. The first guide slope 721 is located below the positioning slope 722. The first guide slope 721 is connected to the positioning slope 722, which facilitates guiding the adjustment assembly 8 from the first guide slope 721 to the positioning slope 722. When the adjustment assembly 8 abuts against the positioning slope 722, it can drive the movable guide member 72 downward. The provision of the positioning slope 722 can better drive the movable guide member 72 downward. When the accommodating tube 5 is in a vertical position, the movable guide member 72 is located above the adjustment assembly 8.
[0035] like Figure 8 As shown, the limit block 73 has a receiving groove 731, which is used to accommodate the movable guide member 72. When the movable guide member 72 is completely located in the receiving groove 731, the positioning inclined surface 722 of the movable guide member 72 is connected to the side wall of the limit block 73, so that the adjustment assembly 8 can smoothly and passively slide from the movable guide member 72 to the limit block 73. In other embodiments, the positioning inclined surface 722 may not be connected to the side wall, and the outer edge of the positioning inclined surface 722 may be located outside the side wall of the limit block 73, that is, the width of the movable guide member 72 is greater than or equal to the width of the limit block 73, and the adjustment assembly 8 can be smoothly and passively slid from the movable guide member 72 to the limit block 73.
[0036] Each adjustment assembly 8 includes a positioning tongue 81, a connecting sleeve 82, a support rod 83, and a second return spring 84. The positioning tongue 81 is used to abut against the pressing member 71 and the limit block 73 of the adjustment assembly 8. The positioning tongue 81 and the support rod 83 are mounted on the connecting sleeve 82 and are located on both sides of the connecting sleeve 82. The positioning tongue 81 is inserted through the inner ring, and the support rod 83 is inserted through the outer support ring 42. The connecting sleeve 82 is movably connected to the accommodating tube 5 and is used to push the accommodating tube 5 to change its state. The second return spring 84 is mounted on the support rod 83 to reset the connecting sleeve 82 and the positioning tongue 81. When the positioning tongue 81 moves away from the accommodating disk 4, the connecting sleeve 82 moves with the positioning tongue 81. The movement of the connecting sleeve 82 thereby pushes the accommodating tube 5 to tilt.
[0037] like Figure 9As shown, the connecting sleeve 82 is provided with a push rod 821, which is used to push the accommodating tube 5 to deflect. There are two push rods 821, one on each side of the accommodating tube 5, to ensure that the accommodating tube 5 does not rotate. The push rods 821 are screwed onto the connecting sleeve 82, which facilitates assembly of the push rods 821 onto the connecting sleeve 82. The accommodating tube 5 is provided with a slide groove 52, which is axially arranged on the outer wall of the accommodating tube 5. The slide groove 52 cooperates with the push rod 821 on the connecting sleeve 82. The push rod 821 extends into the slide groove 52 and slides within the slide groove 52, thereby pushing the accommodating tube 5 to deflect.
[0038] The front end of the positioning tongue 81 is provided with a second guiding slope, that is, the second guiding slope is located at an end close to the center of the receiving tray 4. The upper end of the second guiding slope is farther from the center of the receiving tray 4 than the lower end of the second guiding slope, so as to facilitate cooperation with the first guiding slope 721 of the movable guide member 72.
[0039] like Figure 10 As shown, the fixing seat 6 includes a support seat 61 and a locking cap 62. The support seat 61 is provided with a hemispherical support groove 611. The lower end of the accommodating tube 5 has a spherical connecting portion 51. The connecting portion 51 is provided in the support groove 611. The locking cap 62 is screwed on the support seat 61 to limit the connecting portion 51 on the support seat 61. The connecting portion 51 can be deflected at a certain angle in the support seat 61.
[0040] When in use, first place the reagent tube into the containing tube 5 , at which time the containing tube 5 is in a vertical state, and the positioning tongue 81 abuts against the pressing member 71 and the limit block 73 at the same time, and the positioning tongue 81 is located below the movable guide member 72 . If the locking cam 721 is in the unlocked position, the locking cam 722 will be in the unlocked position, and the locking cam 723 will be in the unlocked position, and the locking cam 724 will be in the unlocked position, and the locking cam 723 will be in the unlocked position, and the locking cam 724 will be in the unlocked position, and the locking cam 723 will be in the unlocked position, and the locking cam 723 will be in the unlocked position, and the locking cam 723 will be in the unlocked position, and the locking cam 723 will be in the unlocked position, and the locking cam 723 will be in the unlocked position, When the locking cam 72 is in the unlocked position, the locking cam 72 is in the unlocked position, and the locking cam 72 is in the unlocked position, so that the locking cam 72 is in the unlocked position, and the locking cam 72 is in the unlocked position, and the locking cam 72 is in the unlocked position, and the locking cam 72 is in the unlocked position, and the locking cam 72 is in the unlocked position, and the locking cam 72 is in the unlocked position, and the locking cam 72 is in the unlocked position, Due to the wider pressing rod 711 of the stopper 73, the positioning latch moves away from the receiving tray 4 compared to its initial position. This also causes the connecting sleeve 82 to move away from the receiving tray 4, thereby tilting the receiving tube 5. After the tilt adjustment of the receiving tube 5 is completed, the driver 3 is activated to rotate the receiving mechanism. This can be indirect rotation in the same direction or intermittent reciprocating rotation. After a predetermined rotation period, the driver 3 stops, completing the mixing process. The pressing member 71 is then gently pressed, causing the stopper 73 to move upward. When the positioning latch 81 aligns with the pressing member 71 between the movable guide 72 and the stopper 73, the second return spring 84 causes the connecting sleeve 82 and positioning latch 81 to return to their original position, moving toward the center of the receiving tray 4. This in turn causes the receiving tube 5 to return to its upright position. The first return spring 75 then forces the pressing member 71 to engage the stopper 73 with the positioning latch 81, maintaining this position.
[0041] During the process of rotating the accommodating tube 5, the accommodating tube 5 is tilted, so that the mixing effect is better, and the state of the accommodating tube 5 can be changed by pressing, which is simple, convenient and fast to operate.
[0042] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention's description and drawings, directly or indirectly applied to other related technical fields, is also within the patent protection scope of the present invention.
