Description

Technical Field

[0001] The present invention relates to the technical field of liquid sampling devices, in particular to a liquid sampling device for experiments. Background Art

[0002] When conducting experiments, different liquid reagents will be pre-placed in each different test tube, and then the liquid reagents in each test tube will be sampled through a sampler and dripped into the corresponding liquid reagent experimental reaction tank for experiments and observations. Therefore, an experimental liquid sampling device will be used.

[0003] Although the existing experimental liquid sampling device can sample a single or multiple liquid samples at the same time, during the experiment, multiple liquid samples of the same type will be transported to the unpowered roller conveyor belt through a feeder for buffering and grouping, and the liquid samples are not continuous when grouped on the unpowered roller conveyor belt. The existing experimental liquid sampling device adopts timed sampling. When the liquid sample grouping time is long, the timed sampling liquid sampling device is difficult to accurately sample the grouped liquid samples, which will not only cause the sampler to collide with the liquid sample and damage the liquid sample, but also cause the sampler to be unable to sample, affecting the accuracy of the sampling results. Therefore, we propose an experimental liquid sampling device. Summary of the Invention

Subsequently, after the liquid sample moves to the interior of the storage frame, the baffle is reset to the inclined state under the influence of gravity, thereby limiting the liquid sample and preventing the liquid sample from slipping from the inside of the storage frame during transportation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Through the cooperation of the feeder, the non-powered roller conveyor belt, the lifting device, the adjusting device, the power device and the pressure device, the pressure block pushes the lower pressure plate to move downward through the pad, and the lower pressure plate drives the lower pressure block to move downward, and the lower pressure block drives the storage clamp to move downward through the fixed block, and the storage clamp drives the sampler to move downward, so that the sampler penetrates into the interior of the liquid sample to sample the liquid, so that after the grouped liquid samples reach the specified number, the sampler can accurately sample the grouped liquid samples, which can not only prevent the sampler from colliding with the liquid sample, but also save sampling time and improve the accuracy of the sampling results.

[0020] 2. The load-bearing frame is driven to move by pushing the slider, and the load-bearing frame drives the positioning plate to move, and the positioning plate drives the inclined plate to move through the connecting shaft, and the inclined plate drives the transmission plate to move through the transmission rod. The mounting hole provided on the transmission plate cooperates with the transmission rod, and the position of the transmission rod on the transmission plate is adjusted, thereby adjusting the distance between the transmission plate and the lower pressure plate, thereby adjusting the number of each group of liquid samples, thereby meeting the sampling of liquid samples for different experiments and improving the convenience of the device.

[0021] 3. The reset rod is driven to move by the pad, so that the reset rod drives the second spring to deform, and the elastic force generated by the deformation of the second spring drives the pad to reset. The impact force generated by the pressure block is buffered by the buffer pad on the pad to prevent the pad from direct contact with the pressure block, thereby improving the service life of the pad and the pressure block and increasing the service life of the device.

[0022] 4. The gravity of the shielding plate drives the shielding plate to move downward around one end of the transmission shaft, so that the shielding plate is in an inclined state. When the liquid sample contacts the shielding plate, the liquid sample pushes the shielding plate from the inclined state to the horizontal state. Then, after the liquid sample moves to the inside of the storage frame, the shielding plate is affected by gravity and resets to the inclined state, limiting the liquid sample to prevent the liquid sample from slipping from the inside of the storage frame during transportation, thereby improving the safety of the device.

[0058] Finally, reference Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 、 Figure 15 and Figure 16 As shown, a storage frame 8 for storing samples is provided on the side of the unpowered roller conveyor belt 3. The middle part of the storage frame 8 is recessed inward to form a storage tank for storing samples, and two insertion rods 13 are provided at the bottom of the storage frame 8 to fix it. After the storage frame 8 is installed on the unpowered roller conveyor belt 3 through the insertion rods 13, the telescopic end of the electric hydraulic rod 11 drives the temporary storage frame 10 to move to the storage tank of the storage frame 8 for storage, thereby facilitating the staff to uniformly transfer a large amount of liquid samples.

[0059] A baffle plate 14 is rotatably installed at one end of the storage frame 8, and a transmission shaft is provided inside the baffle plate 14. A card hole adapted to the transmission shaft is provided inside the storage frame 8, and the transmission shaft is eccentrically installed on the baffle plate 14. The gravity of the baffle plate 14 drives the baffle plate 14 to move downward around one end of the transmission shaft, so that the baffle plate 14 is in an inclined state. When the liquid sample contacts the baffle plate 14, the liquid sample pushes the baffle plate 14 from the inclined state to the horizontal state. Subsequently, after the liquid sample moves to the interior of the storage frame 8, the baffle plate 14 is affected by gravity and resets to the inclined state, thereby limiting the liquid sample and preventing the liquid sample from slipping from the inside of the storage frame 8 during transportation.

[0060] By adopting the above technical solutions:

[0061] When in use, the gravity of the shielding plate 14 drives the shielding plate 14 to move downward around one end of the transmission shaft, so that the shielding plate 14 is in an inclined state. When the liquid sample contacts the shielding plate 14, the liquid sample pushes the shielding plate 14 from the inclined state to the horizontal state. Subsequently, after the liquid sample moves to the inside of the storage frame 8, the shielding plate 14 is affected by gravity and resets to the inclined state, limiting the liquid sample to prevent the liquid sample from slipping from the inside of the storage frame 8 during transportation, thereby improving the safety of the device.

[0062] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
