Description

Technical Field

[0001] The utility model belongs to the technical field of geological and mineral exploration equipment, and specifically relates to an engineering geological exploration sample storage device which has the advantages of reliable clamping and fixing of different samples, convenient operation, strong practicability and convenient access. Background Art

[0002] Engineering geological survey is a geological survey and research work that provides services for national economic construction based on the requirements of construction projects, with natural sciences and earth sciences as its theoretical basis, geological surveys, surveys and explorations of mineral resources, and engineering problems related to the geological structure and geological background of major projects as its main objects, and using geology, geophysics and geochemistry techniques, mathematical geological methods, remote sensing technology, testing technology, computer technology, etc. as means.

[0003] During the engineering geological survey, geological and mineral samples need to be collected and stored. At present, for engineering geological survey samples, they are generally put into plastic self-sealing bags after sampling, and then marked on the bag body, and then directly put into sample boxes or sample bags for storage and transportation, and finally sent back to the laboratory for sample analysis. The above-mentioned method of directly storing samples after being sealed in plastic bags is not only extremely inconvenient for later sample searches when the sampling area is large, the number of samples is large, and the sampling points are distinguished from different geological bodies, but also because the samples are not fixed, they are easily scattered and contaminated due to collisions during long-distance transportation, which has a greater impact on the later detection links.

[0004] In the prior art, in order to solve the problems of storage and transportation of engineering geological survey samples, a fixed plate is fixed on the upper part of a circular storage box, and a plurality of storage tubes are arranged circumferentially on the fixed plate to store the samples, and then a threaded rod is vertically arranged in the middle of the fixed plate to drive the lifting plate under the storage tube, so that the push rods extending upward into the storage tube through the rotating threaded rod are driven by the lifting plate, and the fixed rod at the bottom of the sealing cover that can extend downward into the storage tube can be clamped and fixed to effectively prevent the samples from shaking and being damaged during storage. However, the device clamps and fixes the samples through the movable push rod and the fixed rod. If the samples placed in different storage tubes are of different sizes, after the push rod and the fixed rod fix the largest sample in the storage tube, it is difficult to fix other smaller samples, which results in certain limitations in fixing the samples in different storage tubes. To this end, a number of mounting holes for inserting sample cups are provided in the sample storage box, and a clamping mechanism is provided in the side wall of the mounting hole of the box, and sponge pads are provided in the box and the box cover, respectively, so that the sample cup can be conveniently inserted into the mounting hole, and samples of different sizes can be loaded into the sample cup and filled with cushion pads inside, and fixed in the box by the clamping mechanism, and there is also a wrapping cushion of the sponge pad, which can ultimately prevent samples of different sizes from colliding during storage and transportation. However, since the sample cup needs to be provided with a structure connected with the clamping mechanism, and each sample cup needs to be provided with an independent clamping mechanism, the overall structure is relatively complicated, and the cup body and the cup cover are connected by a screw, and the sample needs to be rotated and separated to take and put, which makes the sample taking and putting relatively cumbersome.

[0040] The working principle and working process of this utility model:

[0041] like Figures 1 to 5 As shown, before use, the overall condition of the device needs to be checked to ensure that it can work normally. During operation, samples are placed in different storage boxes 4 and marked, and then the two sliding sleeves 512 are pressed at the same time to make the sliding sleeves 512 slide along the support rod 511 toward the side of the fixed sleeve 506. The movement of the sliding sleeve 512 drives the connecting rod 513 to rotate, and the limiting rod 507 is pulled by the bottom rod 509 to slide on the fixed sleeve 506 and stretch the telescopic spring 510, so that the limiting rod 507 is separated from the limiting groove 508 on the fixed rod 504, and the movable sleeve 505 loses its limit position, so that the movable sleeve 505 can be moved to drive the installation rod 502 to slide along the through groove I401 and the through groove II101 to drive the movable plate 501 to move, and the movable sleeve 505 can be moved. The plate 501 drives the sliding block 514 to slide in the sliding groove 402, so that the movable plate 501 drives the sample in the corresponding storage box 4 to fit with the fixed plate 201 on the top to achieve clamping and fixing. Then, the movable sleeve 505 can be slightly moved to align the limiting rod 507 with the adjacent limiting groove 508. Then, the sliding sleeve 512 is released, and the telescopic spring 510 restores its deformation to make the limiting rod 507 engage with the limiting groove 508, thereby limiting the movable plate 501 and completing the fixed positioning of the sample. The samples in different storage boxes 4 can be fixed one by one by moving the component 5, and some samples will not be unable to be fixed due to the size of the samples, thereby improving practicality.

[0042] The samples are fixed in different storage boxes 4. When the samples need to be taken out, the movable sleeve 702 can be pulled to slide along the rotating rod 701 to stretch the reset spring 703, so that the positioning block 705 on the mounting plate 704 is disengaged from the corresponding positioning groove 202 on the cover plate 2. Then, the mounting plate 704 is rotated to the outside of the cover plate 2 so that the cover plate 2 loses its limiting effect on the mounting plate 704. The cover plate 2 can be opened to facilitate the removal of samples from the storage box 4. Conversely, the positioning block 705 and the positioning groove 202 can be engaged to limit the cover plate 2. Under the pulling force of the reset spring 703, the cover plate 2 can be prevented from separating from the shell 1, thereby improving the reliability of sample clamping in the storage box 4.

[0043] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
