Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of core storage equipment, in particular to a storage box for core sampling in geotechnical engineering survey. Background Art
[0002] Core sampling, also known as core drilling sampling, is a sampling work carried out on the core or mineral core obtained by drilling, and the core sampling is generally cylindrical. Because the geological core data is very important, it needs to be placed in the core storage box in order, and it takes a long time to transport it to the research institute.
[0003] In order to preserve the integrity of the core during transportation, that is, to prevent the core from colliding with the box, the distance between the two baffles of the existing core storage box is usually slightly larger than the diameter of the core. This makes it time-consuming and laborious for researchers to remove the core from the sampling storage device, and may also cause fingers to be pinched.
[0004] Based on the above situation, the utility model provides a storage box for rock core sampling in geotechnical engineering investigation, which is easy to take out the rock core. Utility Model Content

The storage box is rotatably connected to the dust cover, and the dust cover is fixedly connected to a pair of clamping blocks. It also includes a top block and a trigger mechanism. The storage box is rotatably connected to a plurality of axially distributed top blocks, and the storage box is provided with a trigger mechanism for rotating the top block.
[0007] Optionally, the trigger mechanism includes a pressure block, a connecting rod and a spring, the storage box is slidably connected to a pair of pressure blocks, a connecting rod is fixed between the pairs of pressure blocks, a spring is fixed between the storage box and the pressure blocks, and movement of the connecting rod will cause the top block to rotate.
[0008] Optionally, it also includes an expansion block, a connecting frame, an elastic member and a push block. The storage box is slidably connected to the expansion blocks that are axially distributed in pairs. An elastic member is fixedly connected between the storage box and the expansion block. The connecting rod is fixedly connected to the connecting frame. The connecting frame is fixedly connected to the push blocks that are axially distributed in pairs. The movement of the push block will squeeze the expansion block, causing the expansion block to move.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model uses components such as a pressing block, a lifting block and a spring, so that when researchers open the storage box and want to take out the core, the lifting block directly lifts one side of the core, making it convenient for researchers to take it out.
[0013] 2. The utility model uses the connecting frame, the elastic member and the expansion block and other components, so that when the researcher opens the storage box and wants to take out the core, the expansion block moves to both sides of the core, leaving space for the researcher's hands to grab the core and preventing the fingers from being pinched.

DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.
[0026] Example 1
[0027] A storage box for core sampling in geotechnical engineering investigation, such as Figure 1-Figure 5 As shown, it includes a storage box 1, a dust cover 11 and a clamping block 12. The dust cover 11 is rotatably connected to the top of the storage box 1. A pair of clamping blocks 12 are fixed to the front side of the dust cover 11. The clamping block 12 is used to fix the storage box 1 and the dust cover 11. It also includes a top block 2 and a trigger mechanism. A plurality of axially distributed top blocks 2 are rotatably connected inside the storage box 1. The storage box 1 is provided with a trigger mechanism for rotating the top block 2.
[0028] like Figure 4 and Figure 5 As shown, the trigger mechanism includes a pressure block 21, a connecting rod 22 and a spring 23. A pair of pressure blocks 21 are slidably connected on the left and right sides of the storage box 1. Closing the dust cover 11 will cause the pressure blocks 21 to move downward. A connecting rod 22 is fixed between the pair of pressure blocks 21. A spring 23 is fixed between the storage box 1 and the pressure blocks 21. The spring 23 is used to lift the pressure blocks 21. Movement of the connecting rod 22 will cause the top block 2 to rotate.
[0029] like Fig. 9 and Fig.10 As shown, it also includes a placement clamp 4, a rotating shaft 41 and a stop block 42. A plurality of axially distributed rotating shafts 41 are rotatably connected inside the storage box 1. The rotating shaft 41 enables the placement clamp 4 and the stop block 42 to rotate along with the core. The placement clamp 4 is fixedly connected to the top of the rotating shaft 41, and the stop block 42 is fixedly connected to the front side of the rotating shaft 41. The stop block 42 is used to prevent the core from sliding up and down and hitting the inner wall of the storage box 1.
[0030] After the researchers put the core on the top block 2 and the placement clamp 4, the presence of the stopper 42 can prevent the core from sliding back and forth during transportation and hitting the inner wall of the storage box 1, causing damage to the core. Then the dust cover 11 is covered, and the dust cover 11 presses down the pressure block 21, so that the pressure block 21 moves downward, the spring 23 is compressed, and the connecting rod 22 also moves downward, the top block 2 and the core are rotated to be parallel to the storage box 1, and then the clamping block 12 is moved to clamp the dust cover 11 and the storage box 1 to complete the storage; when the researchers want to take out the core, they first move the clamping block 12 to open the dust cover 11. Since the pressure block 21 is no longer restricted by the dust cover 11, the pressure block 21 moves upward under the action of the spring 23 resetting, and the connecting rod 22 also moves upward, lifting the top block 2 and the core therein together. Since the core rotates and tilts, the placement clamp 4 and the stopper 42 also rotate to tilt upward and correspond to the core, which is convenient for researchers to take out.
[0031] Example 2
[0032] On the basis of Example 1, Figure 6-Figure 8 As shown, it also includes an expansion block 3, a connecting frame 31, an elastic member 32 and a push block 33. The storage box 1 is slidably connected inside with a pair of axially distributed expansion blocks 3, and the expansion block 3 is used to prevent the core from moving left and right in the storage box 1. A pair of elastic members 32 are fixed between the storage box 1 and the expansion block 3. The bottom of the connecting rod 22 is fixedly connected to a connecting frame 31, and the top of the connecting frame 31 is fixedly connected to a pair of axially distributed push blocks 33. The top of the push block 33 is designed as a slope. The upward movement of the push block 33 will squeeze the expansion block 3, causing the expansion block 3 to move to both sides.
[0033] When the researchers want to take out the core, they first open the dust cover 11, and the pressing block 21 and the connecting rod 22 move upward under the action of the spring 23 returning to its original position, and the connecting frame 31 also drives the push block 33 to move upward. The upward movement of the push block 33 squeezes the expansion block 3 to move away from the core, and the elastic member 32 is immediately compressed, leaving space for the researchers to reach out and take the core; when the dust cover 11 is covered, the pressing block 21 and the connecting rod 22 move downward, and the connecting frame 31 also drives the push block 33 to move downward. When the push block 33 no longer squeezes the expansion block 3, the expansion block 3 moves toward the core direction under the action of the elastic member 32 returning to its original position, clamping the core left and right.
