DETAILED DESCRIPTION
[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0022] like Figures 1-10The laboratory titration analyzer shown includes a titration analyzer 1, a fixed column 2 is fixedly connected to the outside of the titration analyzer 1, and the fixed column 2 can provide an installation position. A connecting frame 3 is provided on the outside of the fixed column 2. The connecting frame 3 can be installed on the outside of the fixed column 2 and can use the fixed column 2 to limit the connecting frame 3. A titration pump 4 is fixedly connected to the side of the connecting frame 3 away from the fixed column 2. A stable anti-dumping mechanism 5 is provided on the top of the titration analyzer 1. The stable anti-dumping mechanism 5 is used to prevent the liquid storage bottle 9 from tipping over or to keep the liquid storage bottle 9 stable. The top of the stable anti-dumping mechanism 5 is provided with an upper stabilizing mechanism 6, which is used to maintain the stability of the middle part of the liquid storage bottle 9, and can drive the stable anti-dumping mechanism 5 to keep the liquid storage bottle 9 stable, thereby preventing the liquid storage bottle 9 on the analyzer from shaking, thereby preventing the liquid inside the liquid storage bottle from shaking, and then preventing the titration analyzer from aspirating liquid when the liquid is aspirated, thereby improving the accuracy of the analysis result. The bottom of the titration pump 4 is provided with a capping mechanism 7, which can adapt to bottlenecks of various calibers.
[0023] The stable anti-dumping mechanism 5 includes an anti-dumping ring 501, which provides an installation position. A plurality of through grooves 502 are provided inside the anti-dumping ring 501. The top of the anti-dumping ring 501 is fixedly connected with a mounting ring 503. The mounting ring 503 can provide an installation position. The top of the mounting ring 503 is fixedly connected with a push spring 504. The top of the push spring 504 is fixedly connected with a movable ring 505. The movable ring 505 can provide an installation position and can maintain a certain height under the action of the push spring 504. A plurality of rotating arms 509 are rotatably connected at the outer edge of the mounting ring 503. The rotating arms 509 can penetrate the interior of the through grooves 502, so that the bottom of the rotating arms 509 can be against the liquid storage bottle 9. The outer bottom end can maintain the stability of the liquid storage bottle 9 and prevent the liquid storage bottle 9 from tipping over. A plurality of push-pull rods 510 are rotatably connected to the outer periphery of the movable ring 505. The push-pull rods 510 can push the bottom of the rotating arm 509 to rotate toward the middle when the movable ring 505 moves downward, so that the bottom of the rotating arm 509 can be against the outer bottom end of the liquid storage bottle 9. When the movable ring 505 moves upward, the push-pull rods 510 can be pulled to move upward, and then the rotating arm 509 can be driven to rotate upward, so that the bottom of the rotating arm 509 rotates outward, and then the bottom of the rotating arm 509 no longer can be against the outer bottom end of the liquid storage bottle 9. The bottom of the push-pull rod 510 is rotatably connected to the middle of the rotating arm 509. The outside of the mounting ring 503 is fixedly connected with a plurality of fixed blocks 506, which can provide a mounting position, and the top of the fixed block 506 is fixedly connected with a stabilizing column 507, and the outside of the movable ring 505 is fixedly connected with a plurality of sliding blocks 508. After the sliding block 508 slides on the outside of the stabilizing column 507, it can maintain the stability of the movable ring 505 sliding upward, so that the movable ring 505 will not deviate or shake during the up and down movement, and the middle part of the sliding block 508 is slidably connected to the outside of the stabilizing column 507, and the top of the stabilizing column 507 is fixedly connected with a limiting block 511, which can prevent the sliding block 508 from sliding out of the outside of the stabilizing column 507, thereby playing a limiting role. When the bottom of the rotating arm 509 is released, the movable ring 505 is released. At this time, since the upper stabilizing mechanism 6 is tightly against the outside of the liquid storage bottle 9, after the movable ring 505 is released, the supporting force inside the movable ring 505 causes the movable ring 505 to move downward under the action of the gravity of the liquid storage bottle 9, and then can drive the push-pull rod 510 to move downward, thereby driving the middle part of the rotating arm 509 to rotate toward the middle with the top of the rotating arm 509 as the center of the circle, thereby enabling the bottom of the rotating arm 509 to move toward the middle, and then enabling the bottom of the rotating arm 509 to abut against the outer bottom end of the liquid storage bottle 9, thereby maintaining the stability of the liquid storage bottle 9 and preventing the liquid storage bottle 9 from tipping over. When the liquid storage bottle 9 is pulled up,This can drive the upper stabilizing mechanism 6 to move downward, and can drive the push-pull rod 510 to move upward, and then can drive the rotating arm 509 to move outward, so that the rotating arm 509 can release the bottom of the liquid storage bottle 9. Under the restriction of the limit block 511, the movable ring 505 can be prevented from moving out of the range of the stabilizing column 507. At the same time, the push spring 504 can also prevent the movable ring 505 from moving downward, thereby maintaining the height of the movable ring 505.
[0024] The upper stabilizing mechanism 6 includes a plurality of mounting cylinders 601, which can provide mounting positions. The outer bottom ends of the plurality of mounting cylinders 601 are fixedly connected to the top of the movable ring 505. The inner sliding connection of the mounting cylinder 601 is a limiting ring 602, which has a limiting function. The side of the limiting ring 602 close to the liquid storage bottle 9 is fixedly connected to a movable rod 603, which has a connecting function and can use the limiting ring 602 to maintain the stability of the movable rod 603. The side of the movable rod 603 away from the limiting ring 602 is fixedly connected to an anti- The slide plate 605 and the anti-slide plate 605 can be pressed against the outside of the liquid storage bottle 9 and can increase the friction force. A pressing spring 604 is provided inside the mounting cylinder 601. The pressing spring 604 can provide elastic force so that the pressing spring 604 can push the movable rod 603 and the anti-slide plate 605 to be close to the outside of the liquid storage bottle 9. One end of the pressing spring 604 is fixedly connected to the inside of the movable rod 603, and the other end of the pressing spring 604 is fixedly connected to the inside of the mounting cylinder 601. The outside of the movable rod 603 passes through the side of the mounting cylinder 601 close to the liquid storage bottle 9. The anti-slide plate 605 The side close to the liquid storage bottle 9 is provided with anti-slip grooves. When placing the liquid storage bottle 9, the connecting frame 3 is first rotated to the side away from the liquid storage bottle 9, and the movable ring 505 is pinched to place the liquid storage bottle 9 between the multiple upper stabilizing mechanisms 6. Since the top of the anti-slide plate 605 is an inclined surface, when the liquid storage bottle 9 is pushed downward, the anti-slide plate 605 can be moved outward, and the limiting ring 602 can be driven to move outward, and the pressing spring 604 can be compressed. At the same time, the pressing spring 604 will give a reaction to the movable rod 603 The anti-skid plate 605 exerts a reaction force on the liquid storage bottle 9, so that the anti-skid plate 605 is tightly pressed against the outside of the liquid storage bottle 9, thereby maintaining the stability of the middle part of the liquid storage bottle 9. The anti-dumping mechanism 5 and the upper stabilizing mechanism 6 can maintain the stability of the liquid storage bottle 9 during detection and analysis, thereby preventing the liquid storage bottle 9 from shaking, avoiding the shaking of the liquid storage bottle 9 affecting the amount of liquid aspirated, and then ensuring that the high-precision titration analyzer will not have a deviation in the amount of liquid aspirated when aspirating, thereby improving the accuracy of the high-precision titration analyzer in detecting and analyzing liquids.
[0025] The capping mechanism 7 includes a rotating top plate 701, which can provide an installation position. The top of the rotating top plate 701 is fixedly connected with a plurality of latch teeth 702. The outside of the rotating top plate 701 is fixedly connected with a plurality of driving plates 703. The driving plates 703 are convenient for the staff to rotate the rotating top plate 701 and can provide driving conditions. A sliding groove 704 is provided inside the bottom end of the driving plate 703. The bottom of the rotating top plate 701 is rotatably connected with a mounting ring 705. The mounting ring 705 can be installed in a position. The mounting ring 70 5 is slidably connected to a plurality of holding rods 706. When the holding rods 706 move toward the middle, the top of the liquid storage bottle 9 can be stabilized, thereby maintaining the stability of the top of the liquid storage bottle 9. The top of the holding rods 706 is fixedly connected to a slide column 707. The slide column 707 can be slidably connected to the inside of the slide groove 704. When the driving plate 703 rotates, the slide column 707 can be driven to move toward the middle or to the side away from the liquid storage bottle 9. The top of the slide column 707 is set inside the slide groove 704. The outside of the titration pump 4 is fixedly connected with a fixing ring 708, which can provide an installation position. A plurality of limiting grooves 709 are provided on the inner side of the fixing ring 708. The bottom of the fixing ring 708 is fixedly connected with a thrust spring 710. The bottom of the thrust spring 710 is fixedly connected with a driving ring 711. The bottom of the driving ring 711 is fixedly connected with a plurality of second latch teeth 712. The thrust spring 710 can use its own elastic force to reset the driving ring 711 and enable the second latch tooth 712 to engage with the first latch tooth 702, thereby maintaining the stability of the rotating top plate 701. The top of the driving ring 711 is fixedly connected with a plurality of limiting rods 714. The external sliding connection of the limiting rod 714 When the locking cam 712 is in the closed position, the locking cam 713 is in the closed position, and the locking cam 714 is in the closed position, so that the locking cam 713 is locked and the locking cam 714 is locked. After the locking cam 711 is unlocked, the locking cam 712 is unlocked, and the locking cam 713 is unlocked, so that the locking cam 712 is unlocked and the locking cam 713 is unlocked. When the bottle neck of the liquid storage bottle 9 is clamped and stabilized, the connecting plate 713 is released at this time, and the driving ring 711 can be driven to move downward under the action of the thrust spring 710, and then the second latch tooth 712 can be driven to move downward, and the second latch tooth 712 can be engaged with the first latch tooth 702, and under the restriction of the limit rod 714 and the limit groove 709, the fixing ring 708 can only move up and down without rotating. Then, when the second latch tooth 712 is engaged with the first latch tooth 702, the rotating top plate 701 can be prevented from rotating, and the sliding column 707 will not be driven to move, so that the pressing rod 706 will no longer be driven to move toward the middle, and the stability of the liquid storage bottle 9 can be maintained.
[0026] Working principle: When placing the liquid storage bottle 9, first rotate the connecting frame 3 to the side away from the liquid storage bottle 9, pinch the movable ring 505, and place the liquid storage bottle 9 between the multiple upper stabilizing mechanisms 6. Since the top of the anti-slide plate 605 is an inclined surface, when the liquid storage bottle 9 is pushed downward, the anti-slide plate 605 can be moved outward, and the limiting ring 602 can be moved outward, and the spring 604 can be compressed, and the spring 604 can be pressed at the same time. 4 will give a reaction force to the movable rod 603, which in turn can make the anti-skid plate 605 give a reaction force to the liquid storage bottle 9, so that the anti-skid plate 605 is tightly against the outside of the liquid storage bottle 9. When the bottom of the liquid storage bottle 9 moves to the bottom of the rotating arm 509, the movable ring 505 is released. At this time, since the anti-skid plate 605 is tightly against the outside of the liquid storage bottle 9, after the movable ring 505 is released, the supporting force inside the movable ring 505 makes the movable ring 505 under the weight of the liquid storage bottle 9 When the bottle 9 is lifted up, the upper stabilizing mechanism 6 can be driven downward to move, and the push-pull rod 510 can be driven upward to move, and the rotating arm 509 can be driven to move outward to release the bottom of the bottle 9. The movable ring 505 can be prevented from moving out of the range of the stabilizing column 507 under the restriction of the limit block 511. At the same time, the push spring 504 can be used to prevent the movable ring 505 from moving downward, so as to maintain the height of the movable ring 505. When the locking cam 711 is in the unlocking state, the locking cam 712 is unlocked and the locking cam 713 is unlocked, and the locking cam 712 is unlocked, so that the locking cam 712 is unlocked and the locking cam 713 is unlocked. When the locking cam 712 is in the unlocked position, the locking cam 708 is locked and the locking cam 708 is locked.
