Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to a classification and storage device for surface water sampling. Background Technology

[0002] In environmental monitoring, it is usually necessary to sample and test surface water. During sampling and testing, a sample tube is used to collect the sample, the mouth of the sample tube is sealed, and then the sample tube is sent to the testing equipment for testing. In order to ensure the accuracy of the test, multiple samples are usually collected, that is, multiple sample tubes are used to collect multiple samples for testing.

[0003] When submitting samples for testing, multiple sample tubes need to be stored in a sorting and storage device. In practice, different sample tubes are placed on the same plate at the same time, which is not conducive to distinguishing the sample tubes. When testing samples of the same type, the device raises different types of sample tubes at the same time by extending the cylinder to make them easy to pick up, but this makes it risky to pick up the wrong sample tube.

[0004] Therefore, there is an urgent need to provide a sorting and storage device for surface water sampling to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, which requires multiple sample tubes to be stored in a classification and storage device when submitting samples for testing. In practical applications, different sample tubes are placed on the same placement plate at the same time, which is not conducive to the differentiation of sample tubes. When testing samples of the same type, the device raises different types of sample tubes at the same time by extending the cylinder for easy retrieval. However, this makes it risky to retrieve the sample tubes by mistake. The present invention provides a classification and storage device for surface water sampling.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a classification and storage device for surface water sampling is provided, including a storage box and a box cover disposed on the top of the storage box, wherein the storage box is provided with a first partition and a second partition inside;

[0007] A storage cylinder is provided between the first partition and the second partition, and a locking component is provided at the bottom of the storage cylinder;

[0008] The locking assembly includes a transmission unit disposed at the bottom of the storage cylinder and a positioning unit disposed between the transmission unit and the storage cylinder. An annular groove is formed on the outer surface of the storage cylinder corresponding to the position of the positioning unit.

[0009] A reset component is provided on the outside of the storage cylinder;

[0010] The reset assembly includes a movable ring movably connected to the outer surface of the storage cylinder, a vertical rod movably disposed on the side wall of the movable ring, and a reset component disposed on the outside of the vertical rod. The bottom of the vertical rod is fixedly connected to the top surface of the second partition.

[0011] The present invention is further provided that: a handle is installed on the top surface of the box cover.

[0012] The present invention is further configured such that: the first partition and the second partition have the same structure, and the top surface of the first partition is provided with a plurality of through holes, and the plurality of through holes are equidistantly distributed, and a storage cylinder is movably disposed inside each of the through holes.

[0013] The present invention is further configured such that: the transmission unit includes a fixed seat fixedly connected to the bottom of the inner side of the storage box, a threaded rod movably connected to the bottom of the fixed seat, a sliding sleeve threadedly connected to the outside of the threaded rod, and one end of a connecting rod movably connected to the outer surface of the sliding sleeve.

[0014] The present invention is further configured such that: the transmission unit further includes a slot disposed on the bottom surface of the storage cylinder, the slot having an insert block disposed inside, and the insert block being mounted on the top of the threaded rod.

[0015] The present invention is further configured such that: there are two sets of positioning units, and the two sets of positioning units are arranged opposite to each other on the outside of the transmission unit;

[0016] The positioning unit includes a sliding block movably disposed at the bottom of the second partition and a positioning block installed on the side of the sliding block, wherein the end dimension of the positioning block is adapted to the dimension of the annular groove.

[0017] The present invention is further configured such that a connecting member is provided between the connecting rod and the sliding block;

[0018] The connector includes a storage groove on the bottom surface of the sliding block, one end of an extrusion member installed on the top wall of the storage groove, and a movable block fixedly connected to the other end of the extrusion member. One end of the connecting rod is movably connected to the bottom of the movable block.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses a locking assembly to place the sampling tube inside the storage cylinder. The elastic rubber pad on the inner wall of the storage cylinder provides limiting protection for the sampling tube. It can accommodate sampling tubes of different specifications. After placement, the slot at the bottom of the storage cylinder engages with the insert block at the top of the threaded rod. Rotating the storage cylinder causes the threaded rod to rotate, which in turn causes the sliding sleeve to slide along the length of the threaded rod under the action of the threaded pair. When the sliding sleeve slides, it pulls the connecting rod, which in turn moves the sliding block. This causes the positioning block on the side of the sliding block to engage with the annular groove, thereby limiting and fixing the storage cylinder and preventing the sampling tube from shaking during transportation.

[0021] 2. This utility model, through the setting of locking and resetting components, allows the storage cylinder to be rotated in the opposite direction when the sampling tube needs to be removed. This causes the sliding sleeve to slide upward, which in turn causes the sliding block to separate from the annular groove, thereby releasing the restriction on the storage cylinder. Furthermore, under the elastic action of the resetting component, the movable ring moves upward, causing the storage cylinder to protrude above the first partition. This facilitates the individual handling of different types of sampling tubes, avoids errors, and facilitates testing. Attached Figure Description

The movable ring 71 is laterally rotatably connected to the outer surface of the storage cylinder 5.

[0034] The top surface of the lid 2 is equipped with a handle 21. Preferably, a fastener (not shown in the figure) is provided between the lid 2 and the storage box 1, which is the prior art.

[0035] The first partition 3 and the second partition 4 have the same structure. The top surface of the first partition 3 is provided with multiple through holes 31, which are equidistantly distributed. Each through hole 31 has a storage tube 5 that can be movably installed inside, which can hold multiple sampling tubes at the same time.

[0036] The transmission unit 61 includes a fixed base 611 fixedly connected to the bottom of the inner side of the storage box 1, a threaded rod 612 movably connected to the bottom of the fixed base 611, a sliding sleeve 613 threadedly connected to the outside of the threaded rod 612, and one end of a connecting rod 614 movably connected to the outer surface of the sliding sleeve 613.

[0037] The transmission unit 61 also includes a slot 615 disposed on the bottom surface of the storage cylinder 5. The slot 615 is provided with a plug 616 inside. The plug 616 is installed on the top of the threaded rod 612. Preferably, the cross-sections of the plug 616 and the slot 615 are both polygonal, which improves the stability of the connection between the storage cylinder 5 and the threaded rod 612.

[0038] There are two sets of positioning units 62, which are arranged opposite to each other on the outside of the transmission unit 61.

[0039] The positioning unit 62 includes a sliding block 621 movably disposed at the bottom of the second partition 4 and a positioning block 622 installed on the side of the sliding block 621. The end dimension of the positioning block 622 is adapted to the dimension of the annular groove 63.

After placement, the slot 615 at the bottom of the storage cylinder 5 engages with the insert block 616 at the top of the threaded rod 612. By rotating the storage cylinder 5, the threaded rod 612 is rotated. Under the action of the threaded pair, the sliding sleeve 613 slides along the length of the threaded rod 612. When the sliding sleeve 613 slides, it pulls the connecting rod 614, thereby driving the sliding block 621 to move. The positioning block 622 on the side of the sliding block 621 engages with the annular groove 63, thereby limiting and fixing the storage cylinder 5.

[0043] When the sampling tube needs to be removed, the storage cylinder 5 is rotated in the opposite direction, causing the sliding sleeve 613 to slide upward. This, in conjunction with the connecting piece 64, causes the sliding block 621 to drive the positioning block 622 to separate from the annular groove 63, thereby releasing the restriction on the storage cylinder 5. Furthermore, under the elastic action of the reset piece 73, the movable ring 71 moves upward, causing the storage cylinder 5 to protrude above the first partition 3, making it convenient for personnel to retrieve the sampling tube.
