Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a sampler used for producing chemical reagents. Background Art

[0002] Chemical reagent sampling is the process of taking a certain amount of sample from the reagent container in the laboratory. It is necessary to pay attention to using clean tools, accurate measurement, avoiding contamination, recording information, safe operation, correct storage of samples, labeling and operation according to regulations.

[0003] Most existing chemical reagent samplers have the effect of quantitative sampling. However, when sampling multiple materials, although there are samplers with multiple sampling heads, the sampling heads cannot be adjusted according to the number of samples. Samplers with a single sampling head require multiple samplings and cannot be adaptively adjusted according to the type of samples. Therefore, a sampler for the production of chemical reagents is proposed to solve the above-mentioned problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the embodiment, Figures 1-4 A sampler for producing chemical reagents is provided. The utility model includes a sampling tube 1. The bottom of the sampling tube 1 is connected to a sampling head 2. The inside of the sampling tube 1 is connected to a sampling pull rod 3 extending to the outside. The outside of the sampling tube 1 is fixedly connected to a connecting ring 4. A rotating frame 5 is fixedly installed on the outside of the connecting ring 4. The inside of the rotating frame 5 is rotatably connected to a holding rod 6. The other side of the connecting ring 4 is fixedly installed with a mating component 7 that can be connected to the holding rod 6. The inner side of the mating component 7 is clamped with a mating rod 8 extending to the outside.

[0028] Furthermore, a locking pin extending to the inner side of the rotating frame 5 is threadedly connected to the outer side of the rotating frame 5 , and the end of the locking pin is in contact with the holding rod 6 .

[0029] When the state of the gripping rod 6 needs to be changed, the locking pin can be directly loosened and the gripping rod 6 can be adjusted to the required angle, and then the locking pin can be tightened again. By changing the state of the gripping rod 6, the vertical grip can be changed to a vertical grip to adapt to various operating environments.

[0030] Furthermore, the sampling rod 3 is composed of a T-shaped rod and a sealing rubber plug. The top width of the T-shaped rod is equal to the distance between the rotating frame 5 and the back side of the matching component 7. The rotation angle of the holding rod 6 is ninety degrees.

[0031] Furthermore, a matching groove is provided on the outside of the holding rod 6, and the length of the holding rod 6 is consistent with the length of the matching rod 8. A connecting groove is provided on the outside of the T-shaped pull rod, and the connecting groove is adapted to the shape and size of the end of the matching rod 8.

[0032] This arrangement can form a linkage between the sampling rods 3 of the two samplers through the cooperation between the matching rod and the connecting groove, thereby facilitating extraction.

[0033] Furthermore, the mating assembly 7 includes a mating sleeve 71 connected to the rotating frame 5, and a tension spring 72 is fixedly installed on the outside of the mating sleeve 71. The other end of the tension spring 72 is fixedly connected to a pressing plate 73 that forms extrusion with the mating rod 8, and the end of the pressing plate 73 is fixedly connected to a push rod 74 extending to the inside of the mating sleeve 71.

[0034] Furthermore, the bottom of the push rod 74 is beveled on one side away from the axis of the sampling tube 1 , and the diameter of the push rod 74 is adapted to the diameter of the matching groove.

[0035] When the mating component 7 is working, the holding rod 6 is inserted into the mating sleeve 71. During the insertion process, the mating rod 8 and the pushing rod 74 are squeezed, causing it to start pushing the pressing plate 73 to move upward while the spring 72 is stretched. At this time, the holding rod 6 can be detached, and the holding rod 6 continues to be moved until the pushing rod 74 enters the connecting groove under the push of the spring 72, and the connection between the mating component 7 and the mating rod 8 is completed.

[0036] Working principle:

[0037] Under normal circumstances, when it is needed to be used alone, the sampling head 2 can be directly inserted into the reagent, and then the sampling operation can be performed by pulling the sampling rod 3. When multiple coordinated operations are required, the locking pin can be loosened so that it no longer restricts the holding rod 6, and then the holding rod 6 can be bent to a horizontal state and then tightened again by the locking pin;

[0038] Then, the holding rod 6 is connected to the matching component 7, and the sampling pull rod 3 is connected through the matching rod 8. At this time, two samplers are connected in parallel, and simultaneous sampling can be completed by pulling the matching rod 8.
