Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a novel cleaning mechanism for a biochemical analyzer probe. Background Art

[0002] The probe of biochemical analyzer is one of the key components of biochemical analyzer, which is used to accurately absorb and transfer samples or reagents. The design and performance of the probe directly affect the accuracy and reliability of the analysis results.

[0003] Probe cleaning is a key step to ensure analytical accuracy and avoid cross contamination. Currently, biochemical analyzers on the market usually use fixed-position cleaning containers to clean the probes by immersing them in cleaning fluid.

[0004] This design has several obvious disadvantages:

[0005] First, the fixed-position cleaning method cannot ensure that every part of the probe can be cleaned evenly and effectively.

[0006] During the cleaning process, the operator needs to manually lift the probe. Whether the probe is stably cleaned is directly related to whether the operator drives the probe to move smoothly. Obviously, this cleaning method has high labor intensity and unstable operation. Summary of the invention

[0007] The object of the present invention is to provide a novel cleaning mechanism for a biochemical analyzer probe with high stability and compact structure in view of the above problems existing in the prior art.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] A novel cleaning mechanism for a biochemical analyzer probe comprises a cleaning container and a rotating movable mechanism for connecting the probe, the rotating movable mechanism is used to connect the probe, and the connected probe is located in the cleaning container in an initial state, and is characterized in that the rotating movable mechanism comprises a frame, a cylinder, a motor and a transmission shaft, the transmission shaft is vertically arranged and the middle part of the transmission shaft is passed through the frame, a transmission structure 1 is provided between the transmission shaft and the motor, and the transmission structure 1 can be used to drive the transmission shaft to rotate continuously, a transmission structure 2 is provided between the cylinder and the transmission shaft, and the transmission structure 2 can be used to enable the transmission shaft to move smoothly up and down relative to the frame, and the lower end of the transmission shaft has a connecting end for connecting to the probe.

[0010] In the above-mentioned novel cleaning mechanism for biochemical analyzer probes, the transmission structure 1 includes a transmission cylinder which is cylindrical and axially fixed on the frame, the middle part of the transmission shaft is passed through the transmission cylinder, and the rotating shaft of the motor is connected to the transmission cylinder by a transmission belt or a transmission chain.

[0011] In the above-mentioned novel cleaning mechanism for biochemical analyzer probes, a driving wheel is fixedly connected to the rotating shaft of the motor, and the transmission belt or transmission chain is sleeved on the transmission cylinder and the driving wheel.

[0012] In the above-mentioned novel cleaning mechanism for the probe of a biochemical analyzer, the cross section of the transmission shaft is prismatic, and the inner cavity of the transmission cylinder matches the transmission shaft.

[0013] In the above-mentioned new cleaning mechanism for biochemical analyzer probes, the second transmission structure includes a plate-shaped connecting plate, which is arranged horizontally and one end of the connecting plate is fixedly connected to the piston rod of the cylinder, and the upper end of the transmission shaft axially fixes the other end of the connecting plate.

[0014] In the above-mentioned novel cleaning mechanism for biochemical analyzer probes, the other end of the connecting plate has a bearing, the outer ring of the bearing is fixedly connected to the connecting plate, and the upper end of the transmission shaft is fixedly connected to the inner ring of the bearing.

[0015] In the above-mentioned novel cleaning mechanism for biochemical analyzer probes, the connecting end includes a rod-shaped connecting rod and a connecting hole at the lower end of the transmission shaft, the upper end of the connecting rod is embedded in the connecting hole of the transmission shaft and the two are positioned by magnetic attraction, and the lower end of the connecting rod is a flexible sleeve.

[0016] In the above-mentioned novel cleaning mechanism for biochemical analyzer probes, the sleeve is fixedly connected to the lower end of the connecting rod by glue and the sleeve is made of rubber material.

[0017] Compared with the prior art, the novel cleaning mechanism for the biochemical analyzer probe can drive the probe to continuously rotate and move in the cleaning container. During the rotation process, various circumferential parts of the probe can be stably cleaned, and during the up and down movement, various parts of the probe in the length direction can be stably cleaned. Therefore, the cleaning stability is high.

[0018] At the same time, because the probe rotates steadily and moves up and down under the action of the transmission structure 1 and the transmission structure 2, the entire cleaning operation process has a high degree of automation and the cleaning operation is fast.

[0019] In addition, the transmission structure 1 and the transmission structure 2 are both centrally arranged on the frame, so the structure is relatively compact and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0027] like Figure 1 and Figure 2 and Figure 3 As shown, the novel cleaning mechanism for the probe of the biochemical analyzer comprises a cleaning container and a rotating and moving mechanism for connecting the probe, the rotating and moving mechanism is used to connect the probe, and the connected probe is located in the cleaning container in an initial state, the rotating and moving mechanism comprises a frame 1, a cylinder 2, a motor 3 and a transmission shaft 4, the transmission shaft 4 is vertically arranged and the middle part of the transmission shaft 4 is penetrated on the frame 1, a transmission structure 1 is provided between the transmission shaft 4 and the motor 3, and the transmission structure 1 can make the motor 3 drive the transmission shaft 4 to rotate continuously, a transmission structure 2 is provided between the cylinder 2 and the transmission shaft 4, and the transmission structure 2 can make the transmission shaft 4 move up and down smoothly relative to the frame 1, and the lower end of the transmission shaft 4 has a connecting end for connecting with the probe.

[0028] The transmission structure 1 is used to drive the transmission shaft 4 to rotate continuously, and the transmission structure 2 is used to drive the transmission shaft 4 to move up and down relative to the frame 1.

[0029] When the probe is connected to the connection end at the lower end of the transmission shaft 4 , the probe will move up and down and rotate continuously along with the transmission shaft 4 .

[0030] The rotation and up and down movement of the probe in the cleaning container can ensure that all parts of the probe are stably cleaned.

[0031] The transmission structure 1 includes a transmission cylinder 5 which is cylindrical and axially fixed on the frame. The middle part of the transmission shaft 4 passes through the transmission cylinder 5. The rotating shaft of the motor 3 is connected to the transmission cylinder 5 through a transmission belt 6 or a transmission chain.

[0032] A driving wheel 3a is fixedly connected to the rotating shaft of the motor 3, and the transmission belt 6 or the transmission chain is sleeved on the transmission cylinder 5 and the driving wheel 3a.

[0033] The cross section of the transmission shaft 4 is prismatic, and the inner cavity of the transmission cylinder 5 matches the transmission shaft 4 .

[0034] Since the transmission belt 6 is sleeved on the driving wheel 3a and the transmission cylinder 5, when the motor 3 drives the driving wheel 3a to rotate, the transmission cylinder 5 rotates with it under the action of the transmission belt 6. Since the transmission cylinder 5 and the transmission shaft 4 are circumferentially fixed, the transmission shaft 4 can eventually rotate with the transmission cylinder 5, and the probe connected to the transmission shaft 4 rotates with it.

[0035] The second transmission structure comprises a plate-shaped connecting plate 7, which is arranged transversely and one end of which is fixedly connected to the piston rod of the cylinder 2, and the other end of the connecting plate 7 is axially fixed to the upper end of the transmission shaft 4.

[0036] When the cylinder 2 drives the connecting plate 7 to move up and down, since the transmission shaft 4 is connected to the connecting plate 7, the transmission shaft 4 will move up and down together with the connecting plate 7.

[0037] The other end of the connecting plate 7 is provided with a bearing 9 , the outer ring of the bearing 9 is fixedly connected to the connecting plate 7 , and the upper end of the transmission shaft 4 is fixedly connected to the inner ring of the bearing 9 .

[0038] Under the action of the bearing 9 , the transmission shaft 4 can rotate smoothly relative to the connecting plate 7 .

[0039] The connecting end includes a rod-shaped connecting rod 10 and a connecting hole at the lower end of the transmission shaft 4. The upper end of the connecting rod 10 is embedded in the connecting hole of the transmission shaft 4 and the two are positioned by magnetic attraction. The lower end of the connecting rod 10 is a flexible sleeve 11.

[0040] The magnetic attraction method can make the connecting rod 10 quickly and stably connected to the lower end of the transmission shaft 4. The flexible sleeve 11 can be stably and tightly connected to the upper end of the probe.

[0041] The sleeve 11 is fixedly connected to the lower end of the connecting rod 10 by glue and is made of rubber material.

[0042] The novel cleaning mechanism for the biochemical analyzer probe can drive the probe to continuously rotate and move in the cleaning container. During the rotation, various circumferential parts of the probe can be stably cleaned, and during the up and down movement, various parts of the probe in the length direction can be stably cleaned. Therefore, the cleaning stability is high.

[0043] At the same time, because the probe rotates steadily and moves up and down under the action of the transmission structure 1 and the transmission structure 2, the entire cleaning operation process has a high degree of automation and the cleaning operation is fast.

[0044] In addition, the transmission structure 1 and the transmission structure 2 are both centrally arranged on the frame, so the structure is relatively compact and has high practical value.

[0045] In this embodiment, the transmission cylinder 5 has an annular protruding shoulder 5a at its upper end, and the frame 1 has a cylindrical connecting cylinder 12 , which is sleeved on the transmission cylinder 5 , and the shoulder 5a is located directly above the connecting cylinder 12 .

[0046] The boss 5a has a recessed positioning notch, the upper part of the ball 13 is embedded in the positioning notch, and the lower part of the ball 13 abuts against the upper end of the connecting tube 12. At the same time, the inner side of the connecting tube 12 has a recessed positioning groove 12a, and also includes a wear-resistant sheet 14 of wear-resistant material, the outer side of the wear-resistant sheet 14 is embedded in the positioning groove 12a, and the inner side of the wear-resistant sheet 14 abuts against the outer side of the transmission tube 5. In this embodiment, the wear-resistant sheet 14 is a graphite sheet.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
