Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a lifting mechanism and an analyzer. Background Art

[0002] An analyzer is an instrument used to test samples. It drips a specific reagent into a test tube containing the sample, detects the changes after the reagent reacts with the sample, and obtains the test result. Different reagents are required for different test items.

[0003] Doctors make judgments about patients' conditions based on test results. In modern medicine, sample testing is widely used, so analyzers used to test samples are usually in a continuous working state after being turned on. In order to prevent reagent exhaustion and affect test efficiency, an automatic reagent replenishment device is set in the analyzer.

[0004] The existing reagent replenishing device uses a vertical track to replace the reagent bottle. During the vertical placement of the reagent bottle, since the reagent tray is at a lower position and the reagent compartment is at a higher position, the vertical stroke is long when the reagent bottle is taken out of the reagent compartment and transferred to the reagent tray. The reagent replenishing device occupies a large space, making the overall size of the analyzer large. Utility Model Content

[0005] The utility model provides a lifting mechanism, aiming to solve the problem that a reagent supplement device occupies a large space, making the overall volume of an analyzer large.

[0006] The utility model is implemented in this way: a lifting mechanism comprises:

[0007] Horizontal track;

[0008] A first vertical track slidably connected to the transverse track;

[0009] At least one level of second vertical track, the upper end of each level of the second vertical track being vertically slidably connected to the vertical track of the previous level; and

[0010] A grabbing portion is vertically slidably connected to the second vertical track of the final stage.

[0011] Optionally, the second vertical track is only one level;

[0012] The lifting mechanism further includes a first connecting portion fixedly arranged at the lower end of the first track, a second connecting portion fixedly arranged on the grabbing portion, and a wheel belt assembly;

[0013] The wheel belt assembly comprises a driven wheel, a wheel belt, and a driving wheel connected to a driving member;

[0014] The driving wheel is arranged at one end of the second vertical track, the driven wheel is arranged at the other end of the second vertical track, and the wheel belt is sleeved on the driving wheel and the driven wheel;

[0015] The first connection portion and the second connection portion are fixedly connected to the wheel belt respectively.

[0016] Optionally, the second vertical track includes a bottom plate and a slide rail arranged on the bottom plate, and an avoidance groove is arranged on the bottom plate, so that the first connecting part passes through the avoidance groove and is fixedly connected to the wheel belt.

[0017] Optionally, position sensors for sensing the position of the second vertical track are respectively disposed at the upper end and the lower end of the first vertical track.

[0018] Optionally, position sensors for sensing the gripping portion are respectively disposed at the upper end and the lower end of the second vertical rail.

[0019] Optionally, the first vertical track and the second vertical track are of equal length.

[0020] Optionally, the clamping structure of the gripping portion is adapted to the outer contour of the body of the reagent bottle.

[0021] The utility model also provides an analyzer, comprising the above-mentioned lifting mechanism.

[0022] Optionally, a reagent tray is further included, and the lifting mechanism is arranged above the reagent tray.

[0023] The beneficial effect achieved by the utility model is that, due to the provision of a transverse track, a first vertical track, at least one second vertical track and a gripping part, the first vertical track slides transversely on the transverse track, the second vertical track slides vertically on the previous vertical track, and the gripping part slides vertically on the last second vertical track.

The upper end of the second vertical track slides vertically with the vertical track of the previous stage, and in the direction in which the total length of the first vertical track and the second vertical track in the vertical direction increases, when performing transverse movement, the first vertical track and the second vertical track can overlap each other in the vertical direction, reducing the total length of the first vertical track and the second vertical track in the vertical direction, saving space above the transverse track, and being conducive to reducing the volume of the equipment.

[0036] Embodiment 1

[0037] like Figure 2 As shown, this embodiment provides a lifting mechanism 100, including:

[0038] Horizontal track 101;

[0039] A first vertical track 102 slidably connected to the horizontal track 101;

[0040] At least one level of second vertical track 103, the upper end of each level of second vertical track 103 is vertically slidably connected to the vertical track of the previous level; and

[0041] A gripping portion 104 is vertically slidably connected to the second vertical rail 103 of the final stage.

[0042] In this embodiment, the transverse track 101 extends in the horizontal direction, and the first vertical track 102 extends in the vertical direction. The first vertical track 102 is slidably connected to the transverse track 101, and the first vertical track 102 can reciprocate along the extension direction of the transverse track 101 on the transverse track 101. The extension direction of the second vertical track 103 is consistent with the extension direction of the first vertical track 102, and the upper end of the second vertical track 103 is vertically slidably connected to the vertical track of the previous level, and can reciprocate along the extension direction of the vertical track of the previous level.

[0043] It can be understood that if the second vertical track 103 is provided at least at one level, the vertical track of the previous level may be the first vertical track 102 or the second vertical track 103. Since the upper end of the second vertical track 103 is connected to the vertical track of the previous level, when a second vertical track 103 moves upward relative to the vertical track of the previous level, the second vertical track 103 and the vertical track of the previous level can overlap to the greatest extent, at which time, the total length of the second vertical track 103 and the vertical track of the previous level is the shortest; when the second vertical track 103 moves downward relative to the vertical track of the previous level, the portion of the second vertical track 103 overlapping with the vertical track of the previous level is the least, at which time, the total length of the second vertical track 103 and the vertical track of the previous level is the longest.

[0044] A gripping portion 104 is provided on the second vertical track 103 of the final stage, and the gripping portion 104 is vertically slidably linked to the second vertical track 103 of the final stage, and the gripping portion 104 reciprocates along the extension direction of the second vertical track 103. The gripping portion 104 is used to grip the reagent bottle, and the gripping portion 104 moves following the first vertical track 102 and the second vertical track 103. After the gripping portion 104 grips the reagent bottle, it drives the reagent bottle to realize horizontal and vertical movements.

[0045] like Figure 1The conventional lifting mechanism 100 is shown, comprising: a transverse track 101 , a first vertical track 102 connected to the transverse track 101 in a transverse sliding manner, and a gripping portion 104 connected to the first vertical track 102 in a vertical sliding manner.

[0046] like Figure 3 As shown, since the first vertical rail 102 moves along the transverse rail 101, in order to avoid the first vertical rail 102 from blocking the surrounding structures or equipment during the movement, the lowest point of the first vertical rail 102 is still a certain distance away from the placement position of the reagent bottle. In order to enable the grasping portion 104 to smoothly grasp the reagent bottle, an extension portion 1041 extending toward the reagent bottle is provided on the grasping portion 104. Due to the existence of the extension portion 1041, when the reagent bottle is grasped to a preset height, the first vertical rail 102 extends to the side away from the reagent bottle, and the extension length is at least equal to the length of the extension portion 1041, resulting in more space above the transverse rail 101 being occupied, so that the overall volume of the traditional lifting mechanism 100 is larger.

[0047] In this embodiment, since the transverse rail 101, the first vertical rail 102, at least one second vertical rail 103 and the gripping portion 104 are provided, the first vertical rail 102 slides transversely on the transverse rail 101, the second vertical rail 103 slides vertically on the vertical rail of the previous stage, and the gripping portion 104 slides vertically on the second vertical rail 103 of the final stage. The upper end of the second vertical rail 103 slides vertically with the vertical rail of the previous stage, and in the direction in which the total length of the first vertical rail 102 and the second vertical rail 103 in the vertical direction increases, when performing transverse movement, the first vertical rail 102 and the second vertical rail 103 can overlap each other in the vertical direction, thereby reducing the total length of the first vertical rail 102 and the second vertical rail 103 in the vertical direction, saving space above the transverse rail 101, and being conducive to reducing the volume of the device.

[0048] Embodiment 2

[0049] On the basis of the first embodiment, the second vertical track 103 is only one level;

[0050] The lifting mechanism 100 further includes a first connecting portion fixedly disposed at the lower end of the first vertical rail 102 and a second connecting portion fixedly disposed on the gripping portion 104, and a wheel belt assembly 105;

[0051] The belt assembly 105 includes a driven wheel 1052, a belt 1053, and a driving wheel 1051 connected to a driving member;

[0052] The driving wheel 1051 is arranged at one end of the second vertical track 103, the driven wheel 1052 is arranged at the other end of the second vertical track 103, and the wheel belt 1053 is sleeved on the driving wheel 1051 and the driven wheel 1052;

[0053] The first connection portion and the second connection portion are fixedly connected to the wheel belt 1053 respectively.

[0054] In this embodiment, the first-level second vertical track 103 is vertically slidably connected to the first vertical track 102, and the gripping portion 104 is vertically slidably connected to the second vertical track 103. The driving wheel 1051 and the driven wheel 1052 are respectively arranged at both ends of the second vertical track 103, and the driving wheel 1051 and the driven wheel 1052 are sleeved with a belt 1053. Under the action of the belt 1053, the driving wheel 1051 drives the driven wheel 1052 to rotate synchronously.

[0055] The belt 1053 sleeved on the driving wheel 1051 and the driven wheel 1052 has two opposite sides, and the belts 1053 on both sides make synchronous reverse movements. When the belt 1053 on one side moves upward, the belt 1053 on the other side moves downward. A first connecting portion is provided at the lower end of the first track, and the first connecting portion passes through the second vertical track 103 and is connected to the belt 1053. The first connecting portion is fixedly connected to the belt 1053 on one side, and the second connecting portion is fixedly connected to the belt 1053 on the other side.

[0056] like Figure 2 As shown, the first connection part is connected to the inner wheel belt 1053, and the second connection part is connected to the outer wheel belt 1053. When the driving wheel 1051 rotates clockwise, the inner wheel belt 1053 moves downward, driving the first connection part to move downward relative to the second vertical track 103, and the second vertical track 103 moves upward relative to the first vertical track 102. The outer wheel belt 1053 moves upward, driving the second connection part to move upward relative to the second vertical track 103. The position of the first vertical track 102 in the vertical direction cannot be changed. When the driving wheel 1051 rotates clockwise, the second vertical track 103 and the grabbing part 104 move upward synchronously. Conversely, when the driving wheel 1051 rotates counterclockwise, the second vertical track 103 and the grabbing part 104 move downward synchronously.

[0057] In this embodiment, the second vertical rail 103 and the grabbing portion 104 move synchronously, and the lifting mechanism 100 has high telescopic efficiency.

[0058] Embodiment 3

[0059] On the basis of the second embodiment, the second vertical track 103 includes a bottom plate 1031 and a slide rail 1032 arranged on the bottom plate 1031 . The bottom plate 1031 is provided with an escape groove 1033 , so that the first connecting portion passes through the escape groove 1033 and is fixedly connected to the wheel belt 1053 .

[0060] In this embodiment, an avoidance groove 1033 is provided on the bottom plate 1031, and the extension direction of the avoidance groove 1033 is consistent with the movement direction of the second vertical track 103 relative to the first vertical track 102. A slide rail 1032 is provided on one side of the bottom plate 1031, and the slide rail 1032 is adapted to the first vertical track 102, driving the bottom plate 1031 to slide vertically on the first vertical track 102. A driving wheel 1051 and a driven wheel 1052 are provided on the other side opposite to the side where the slide rail 1032 is provided, and the driving wheel 1051 and the driven wheel 1052 are provided at both ends of the avoidance groove 1033. The first connecting portion passes through the avoidance groove 1033 and is connected to the wheel belt 1053, and the first connecting portion can move along the avoidance groove 1033 without being blocked on the movement path.

[0061] Embodiment 4

[0062] On the basis of the first embodiment, position sensors for sensing the position of the second vertical track 103 are respectively disposed at the upper end and the lower end of the first vertical track 102 .

[0063] The position sensor is used to sense the position of the second vertical track 103 relative to the first vertical track 102, and send a signal to control the motor to stop, so as to prevent the motor from over-rotating and causing the parts to collide with each other or be damaged. When the second vertical track 103 moves upward, the position sensor set at the upper end of the first vertical track 102 is triggered, and the position sensor sends a signal to control the motor to stop, so as to prevent the second vertical track 103 from continuing to move upward. When the second vertical track 103 moves downward, the position sensor set at the lower end of the first vertical track 102 is triggered, and the position sensor sends a signal to control the motor to stop, so as to prevent the second vertical track 103 from continuing to move downward.

[0064] Embodiment 5

[0065] On the basis of the first embodiment, position sensors for sensing the grabbing portion 104 are respectively disposed at the upper end and the lower end of the second vertical track 103 .

[0066] The position sensor is used to sense the position of the gripping part 104 relative to the second vertical track 103, and send a signal to control the motor to stop, so as to prevent the parts from colliding or being damaged due to over-rotation of the motor. When the gripping part 104 moves upward, the position sensor disposed at the upper end of the second vertical track 103 is triggered, and the position sensor sends a signal to control the motor to stop, so as to prevent the gripping part 104 from continuing to move upward. When the gripping part 104 moves downward, the position sensor disposed at the lower end of the second vertical track 103 is triggered, and the position sensor sends a signal to control the motor to stop, so as to prevent the gripping part 104 from continuing to move downward.

[0067] Embodiment 6

[0068] Based on the first embodiment, the first vertical track 102 and the second vertical track 103 are of equal length.

[0069] In this embodiment, the first vertical track 102 and the second vertical track 103 are of equal length, and when the first vertical track 102 and the second vertical track 103 overlap, the length in the vertical direction is the shortest.

[0070] In Example 1, the first vertical rail 102 is 6 cm, the second vertical rail 103 is also 6 cm, and the length of the connecting portion when extended is 1 cm, so the total length when extended is 10 cm, and the total length when overlapped is 6 cm. In Example 2, the first vertical rail 102 is 7 cm, the second vertical rail 103 is also 5 cm, and the length of the connecting portion when extended is 1 cm, so the total length when extended is 10 cm, and the total length when overlapped is 7 cm.

[0071] According to Example 1 and Example 2, the total length when extended is 10 cm, but the total length when overlapped is less than that of Example 2. When the total length when extended is constant, the first vertical track 102 and the second vertical track 103 are equal in length, and the length when overlapped is the shortest.
