Description

Technical Field

[0001] This invention relates to a sampling device, and more particularly to a rapid sampling device. Background Technology

[0002] In medical testing, samplers are used to extract sample solutions.

[0003] For example, Chinese Patent Publication No. CN210863265U discloses a rapid sampling device for medical testing, comprising a main body in the form of a cylindrical cavity. One end of the main body has a first opening, and a sampling tube, also cylindrical, is located on the side wall of the end of the main body away from the first opening. The sampling tube penetrates the side wall of the main body and is fixedly connected to the main body. A connecting tube is inserted through the center of the end of the sampling tube located on the outer side of the main body. A sampling nozzle is inserted into the outer wall of the connecting tube, and a first piston is slidably connected to the inner wall of the sampling tube. This invention, by setting the main body and including a second piston and a second spring at one end, and a push rod on the second spring, allows air inside the main body to enter the sampling tube through a first one-way valve on the first piston after sampling, thereby generating excess air to expel the sample and avoid sample residue. However, this patent has the following problems: When extracting and testing samples, a single sample often needs to be tested for multiple categories, requiring multiple samplings. However, the aforementioned device can only sample once at a time, requiring operators to perform multiple samplings. This repetitive sampling operation is slow and prone to errors due to repeated mechanical operations. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid sampling device to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid sampling device, comprising a base, a vertical rod fixedly connected to the base near its edge, a lifting plate slidably sleeved on the vertical rod, a hydraulic telescopic rod fixedly connected to the center of the base, an inner core disk fixedly connected to the upper end of the hydraulic telescopic rod, an outer rotating disk rotatably sleeved on the inner core disk, a plurality of snap-fit ​​holes being formed in the outer rotating disk, a sampling needle being placed in each snap-fit ​​hole, the sampling needle comprising a syringe and a piston, the piston sliding within the syringe, a connecting rod fixedly connected to the piston, a pull block fixedly connected to the upper end of the connecting rod, the pull block cooperating with the lifting plate, and a placement groove being formed on the base, in which a beaker is placed.

[0006] Preferably, a control host is fixedly connected to the front of the base.

[0007] Preferably, a limiting groove is provided inside the upright, a drive motor is fixedly connected to the upper end of the upright, and an adjusting screw is fixedly connected to the output end of the drive motor.

[0008] Preferably, the lifting plate has a connecting hole, which cooperates with the upright.

[0009] Preferably, a limiting threaded sleeve is fixedly installed inside the connecting hole, and the connecting hole slides in conjunction with the limiting groove.

[0010] Preferably, the limiting threaded sleeve has a threaded through hole, which is threadedly engaged with the adjusting screw.

[0011] Preferably, an L-shaped snap-fit ​​component is fixedly attached to the inner core disk.

[0012] Preferably, a limiting ring is fixedly attached to the outer wall of the syringe near the upper edge, and the limiting ring cooperates with the L-shaped snap-fit ​​component.

[0013] Preferably, an angle adjustment motor is embedded under the inner core disk, and a rotating gear is fixedly connected to the output end of the angle adjustment motor.

[0014] Preferably, a gear ring is fixedly connected to the underside of the outer rotating disk, and the gear ring meshes with the rotating gear.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By controlling the rotation of the outer rotating disk, different sampling needles are positioned above the container beaker to automatically extract samples. This allows for automated multiple sampling, eliminating the need for manual sampling of test samples repeatedly.

[0016] 2. By directly inserting the sampling needle into the through hole, the L-shaped locking device and the limiting ring work together to restrict the syringe inside the through hole. After the sampling needle rotates and is offset from the position above the beaker, the restriction on the syringe can be released, making it easy to pick up and put down the sampling needle.

[0017] 3. The main control unit controls the start and stop of the drive motor, which can control the rising distance of the lifting plate. In turn, it can control the upward movement distance of the piston as needed, so as to control the amount of sample extracted and adapt to different tests. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-6 As shown, the present invention has the following specific embodiments.

[0022] Example 1 A rapid sampling device includes a base 1, a vertical rod 2 fixedly attached to the base 1 near its edge, a lifting plate 3 slidably sleeved on the vertical rod 2, a hydraulic telescopic rod 401 fixedly attached to the center of the base 1, an inner core plate 4 fixedly attached to the upper end of the hydraulic telescopic rod 401, an outer rotating plate 5 rotatably sleeved on the inner core plate 4, a plurality of snap-fit ​​holes 501 opened in the outer rotating plate 5, a sampling needle 6 placed in the snap-fit ​​holes 501, the sampling needle 6 including a syringe 601 and a piston 602, the piston 602 sliding in the syringe 601, a connecting rod 603 fixedly attached to the piston 602, a pull block 604 fixedly attached to the upper end of the connecting rod 603, the pull block 604 cooperating with the lifting plate 3, and a placement groove 102 opened on the base 1, a beaker 103 placed in the placement groove 102.

[0023] In this embodiment, the sample to be tested is placed inside the beaker 103, and then the beaker 103 is placed inside the placement slot 102. Multiple sampling needles 6 are inserted into the locking holes 501. The outer rotating disk 5 is rotatably connected to the inner core disk 4, allowing the outer rotating disk 5 to rotate freely. This rotation of the outer rotating disk 5 drives the sampling needles 6 to rotate, aligning the lower end of one of the sampling needles 6 with the beaker 103. Activating the hydraulic telescopic rod 401 moves the inner core disk 4 downwards, which in turn moves the outer rotating disk 5 downwards, causing the sampling needle 6 to move downwards, thus inserting the lower end of the sampling needle 6 into the beaker 103. The lifting plate 3 is slidably sleeved on the upright rod 2. Controlling the lifting plate 3 to move upward will cause interference with the pull block 604 during the upward movement of the lifting plate 3. Consequently, the upward movement of the lifting plate 3 will drive the pull block 604 to move upward. The upward movement of the pull block 604 will drive the piston 602 to move upward through the connecting rod 603. The upward movement of the piston 602 can draw the sample to be tested into the syringe 601. By controlling the upward movement distance of the lifting plate 3, the amount of sample drawn can be controlled. Then, the lifting plate 3 is controlled to reset, and the outer rotating disk 5 is rotated again so that the other sampling needle 6 is aligned with the holding beaker 103. The sample can be drawn automatically and repeatedly without the need for manual sampling of the sample to be tested multiple times.

[0024] Example 2 like Figure 1 , 2 As shown in Figure 6, a control host 101 is fixedly connected to the front of the base 1. A limit groove 201 is opened in the upright 2. A drive motor 202 is fixedly connected to the upper end of the upright 2. An adjusting screw 203 is fixedly connected to the output end of the drive motor 202. A connecting hole 301 is opened in the lifting plate 3. The connecting hole 301 cooperates with the upright 2. A limit threaded sleeve 302 is fixedly connected in the connecting hole 301. The connecting hole 301 and the limit groove 201 are in sliding cooperation. A threaded through hole is opened in the limit threaded sleeve 302. The threaded through hole is in threaded cooperation with the adjusting screw 203. An L-shaped snap-fit ​​part 402 is fixedly connected to the inner core plate 4.

[0025] In this embodiment, the control host 101 can control the electrical components of the entire device. After inputting instructions using a preset program, sampling is performed automatically. Starting the drive motor 202 can drive the adjusting screw 203 to rotate. The adjusting screw 203 cooperates with the threaded through hole, and the rotation of the adjusting screw 203 can drive the limiting threaded sleeve 302 to move. The movement of the limiting threaded sleeve 302 can drive the lifting plate 3 to move. The height of the lifting plate 3 is controlled and adjusted. In order to avoid the relative height between the lifting plate 3 and the sampling needle 6 changing when the inner core plate 4 moves down, the control host 101 needs to control the drive motor 202 to start synchronously when the inner core plate 4 moves down and the lower end of the sampling needle 6 is inserted into the beaker 103, so that the lifting plate 3 moves down synchronously with the sampling needle 6.

[0026] Example 3 like Figure 1 , 3 As shown in Figures 5 and 6, a limiting ring 605 is fixedly attached to the outer wall of the syringe 601 near the upper edge. The limiting ring 605 cooperates with the L-shaped snap-fit ​​part 402. An angle adjustment motor 403 is embedded under the inner core disk 4. A rotating gear 404 is fixedly attached to the output end of the angle adjustment motor 403. A gear ring 502 is fixedly attached to the lower part of the outer rotating disk 5. The gear ring 502 and the rotating gear 404 mesh with each other.

[0027] In this embodiment, the limiting ring 605 and the L-shaped locking member 402 cooperate with each other. After the outer rotating disk 5 drives the sampling needle 6 to rotate above the holding beaker 103, the limiting ring 605 will be located below the L-shaped locking member 402. The L-shaped locking member 402 can then restrict the upward movement of the syringe 601. During the upward movement of the piston 602 driven by the lifting plate 3, the syringe 601 is prevented from being synchronously driven upward. As the outer rotating disk 5 continues to rotate, the limiting ring 605 and the L-shaped locking member 402 will be disengaged. At this time, the sampling needle 6 can be easily pulled out from the locking hole 501. The starting angle adjustment motor 403 can drive the rotating gear 404 to rotate. The rotating gear 404 meshes with the gear ring 502. The rotation of the rotating gear 404 can drive the gear ring 502 to rotate, and the rotation of the gear ring 502 can drive the outer rotating disk 5 to rotate.

[0028] The working principle and usage process of this invention are as follows: During use, the sample to be tested is poured into the beaker 103. The beaker 103 is then placed inside the placement slot 102. Multiple sampling needles 6 are inserted into the locking holes 501. The angle adjustment motor 403 is activated, driving the outer rotating disk 5 to rotate. The rotation of the outer rotating disk 5 drives the sampling needles 6 to rotate, aligning the lower end of one sampling needle 6 with the beaker 103. The hydraulic telescopic rod 401 and drive motor 202 are then activated. The hydraulic telescopic rod 401 moves the inner core disk 4 downwards, which in turn moves the sampling needle 6 downwards. The motor 202 can drive the lifting plate 3 to move down synchronously with the sampling needle 6. When the lower end of the syringe 601 is inserted into the beaker 103, the hydraulic telescopic rod 401 is stopped and the motor 202 is started in reverse. At this time, the lifting plate 3 moves up. Through the cooperation of the lifting plate 3 and the pull block 604, the piston 602 moves up inside the syringe 601, thereby drawing the sample into the sampling needle 6. Finally, the motor 202 controls the lifting plate 3 to reset and starts the L-shaped locking piece 402 to move another sampling needle 6 above the beaker 103. The above operation can be repeated to perform the sampling operation again.
