Abstract
Description
Technical Field
[0001] This utility model relates to the field of geotechnical engineering technology, specifically a sample storage box for geotechnical engineering. Background Technology
[0002] Geotechnical exploration is a crucial part of construction project design. By exploring and analyzing soil and rock layers, design schemes can be optimized and construction safety improved. Therefore, after collecting soil and rock samples, specialized equipment is needed for collection and storage. The quality of soil samples is paramount. During drilling and soil extraction, the soil structure is easily disturbed. Using disturbed soil samples for testing will inevitably lead to erroneous conclusions, potentially causing engineering accidents or wasting construction funds.
[0003] After soil and rock samples are collected, they are generally stored in sampling tubes and transferred to testing institutions for analysis. During transportation, it is necessary to avoid deformation or scattering of the soil and rock samples due to vibration and impact as much as possible to reduce the impact of movement on the test results. Currently used storage boxes can generally hold multiple samples at the same time, and the internal shock-absorbing structure can buffer some impact. However, the shock-absorbing effect of this type of structure is limited and cannot independently protect each sample, resulting in the problem of excessive disturbance and interference to the samples. Utility Model Content
[0004] The purpose of this invention is to provide a sample storage box for geotechnical engineering, thereby solving the problems mentioned in the background art. It provides a storage box capable of independently protecting each geotechnical sample, improving shock absorption, enhancing stability, and reducing the impact of transportation on sample accuracy.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A sample storage box for geotechnical engineering includes a box body and storage structures. An installation base is installed inside the box body, and multiple storage structures are installed on the installation base. Each storage structure includes an installation cylinder opened on the installation base, and a primary shock-absorbing component and a fixing component are installed inside the installation cylinder. An extension cylinder protruding from the installation cylinder is installed on the surface of the installation base, and a cylindrical sealing cap is threaded onto the extension cylinder. A secondary shock-absorbing component is slidably installed inside the sealing cap, and a sample tube is installed inside the installation cylinder.
[0007] As a further embodiment of this utility model: the primary shock absorption component includes a primary spring installed inside the mounting cylinder, and a primary washer is installed on the primary spring, the primary washer being made of a flexible material.
[0008] As a further improvement of this utility model: the secondary shock absorption component includes a secondary spring installed inside the sealing cover, and a secondary gasket is installed at one end of the secondary spring near the mounting cylinder. The secondary gasket is made of a flexible material.
[0009] As a further embodiment of this utility model: a pad is installed at the end of the secondary spring away from the secondary washer, a protruding display post is installed on the pad, a through hole is opened on the sealing cover, the display post is inserted into the through hole, and a limiting ring is installed inside the sealing cover between the pad and the secondary washer.
[0010] As a further embodiment of this utility model: the mounting cylinder has an annular mounting groove in the middle, and a fixing component is installed in the mounting groove. The fixing component includes multiple baffles that are rotatably connected to the mounting groove. A torsion spring is installed at the connection between the baffle and the mounting groove. The edge of the baffle is smooth, and the baffle is in pressure contact with the side wall of the sample tube.
[0011] As a further embodiment of this utility model: a lid is rotatably mounted on the box body, a latch connects the box body and the lid, and a pull ring is installed on the lid.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] Using the aforementioned geotechnical engineering sample storage box, this device has multiple mounting cylinders on the mounting base. Each mounting cylinder is used to independently store sample tubes, and each mounting cylinder is equipped with an extension cylinder connected to a sealing cap. Therefore, after the sample tube is placed in, each sample tube is independently sealed. Through the cooperation of the primary and secondary shock absorption components, buffering and shock absorption are provided from both ends, providing sufficient protection and shock absorption for the sample tubes. At the same time, each sample tube is fully fixed. When encountering external shaking or other problems, it avoids shaking caused by voids inside the box and prevents mutual interference between sample tubes. Even if the box is passively opened, the independent fixing effect of each sample tube will not be affected.
[0014] By using the above-mentioned geotechnical engineering sample storage box, this device effectively improves the protection and shock absorption effect, avoids the geotechnical samples from being moved around due to various unforeseen reasons during transportation, reduces sample errors, and improves the sample preservation effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-3 In Embodiment 1 of this utility model, a sample storage box for geotechnical engineering includes a box body 14 and a storage structure 13; a mounting base 12 is installed inside the box body 14, and multiple storage structures 13 are installed on the mounting base 12; the storage structure 13 includes a mounting cylinder 24 opened on the mounting base 12, and a primary shock absorption component 11 and a fixing component 10 are installed inside the mounting cylinder 24; an extension cylinder 8 protruding from the mounting cylinder 24 is installed on the surface of the mounting base 12, and a cylindrical sealing cap 3 is threadedly connected to the extension cylinder 8; a secondary shock absorption component 7 is slidably installed inside the sealing cap 3; and a sample tube 18 is installed inside the mounting cylinder 24.
[0021] The device features a mounting base 12 inside the housing 14. Multiple mounting cylinders 24 for placing sample tubes 18 are located on the mounting base 12. Extended cylinders 8 protrude from the mounting cylinders 24 to connect to sealing caps 3. The sealing caps 3 can be rotated open. After the sample tubes 18 are placed inside, the sealing caps 3 are rotated and tightened, allowing the primary shock-absorbing assembly 11 and the secondary shock-absorbing assembly 7 to support the sample tubes 18 from both ends, providing fixation, protection, and shock absorption. Simultaneously, a fixing assembly 10 is installed in the middle of the mounting cylinders 24 to clamp and fix the inserted sample tubes 18 from the middle, further preventing internal shaking of the sample tubes 18.
[0022] It should be noted that this device mainly uses springs for shock absorption. The purpose is not to counteract external shaking, but to allow the sample tube 18 to shake gently to avoid rigid collisions. Therefore, using springs directly is sufficient to meet the requirements. Using other resistance structures may reduce the buffering effect.
[0023] This device provides ample protection and shock absorption for the sample tubes 18, and protects each sample tube 18 independently to avoid mutual interference during transportation. Even if the box cover 1 is opened, it will not affect the protection of each sample tube 18, minimizing the impact of movement during transportation and improving the accuracy of the test.
[0024] As another embodiment of this utility model, please refer to Figures 1-3 The main difference between Example 2 and Example 1 is that:
[0025] Please see Figures 1-3 In Embodiment 2 of this utility model, the primary shock absorption component 11 includes a primary spring 19 installed inside the mounting cylinder 24. A primary washer 21, made of flexible material, is mounted on the primary spring 19. The primary spring 19 supports the primary washer 21. After the sample tube 18 is inserted, the primary spring 19 is compressed, clamping the sample tube 18 and providing cushioning to prevent the sample tube 18 from being subjected to direct impact.
[0026] Please see Figures 1-3 The secondary damping assembly 7 includes a secondary spring 16 installed inside the sealing cover 3. A secondary gasket 17, made of flexible material, is installed at one end of the secondary spring 16 near the mounting cylinder 24. The secondary spring 16, in conjunction with the secondary gasket 17, applies pressure from the bottom to the sample tube 18 to protect it.
[0027] Please see Figures 1-3 A pad 6 is installed at the end of the secondary spring 16 away from the secondary gasket 17. A protruding display post 5 is installed on the pad 6. A through hole 4 is opened on the sealing cover 3, and the display post 5 is inserted into the through hole 4. A limiting ring 22 is installed inside the sealing cover 3 between the pad 6 and the secondary gasket 17. The pad 6 is locked above the limiting ring 22 to prevent the secondary shock absorption assembly 7 from detaching from the sealing cover 3. The display post 5 protruding from the through hole 4 is installed on the pad 6. When the secondary shock absorption assembly 7 is compressed, the display post 5 extends upward outside the sealing cover 3. When it is not compressed, the secondary shock absorption assembly 7 moves downward to the limiting ring 22, and the display post 5 does not protrude. By observing the display post 5, it is possible to determine whether the sample tube 18 has been placed in the corresponding mounting cylinder 24 without opening the sealing cover 3 to check.
[0028] Please see Figures 1-3The mounting cylinder 24 has an annular mounting groove 9 in the middle. A fixing component 10 is installed in the mounting groove 9. The fixing component 10 includes multiple baffles 20 rotatably connected to the mounting groove 9. A torsion spring 23 is installed at the connection between the baffles 20 and the mounting groove 9. The baffles 20 have smooth edges and make pressure contact with the side wall of the sample tube 18. The fixing component 10, which consists of multiple annularly distributed baffles 20, is installed in the mounting groove 9. The baffles 20 are kept horizontal under the action of the torsion spring 23. During the insertion of the sample tube 18, the baffles 20 rotate downward at a certain angle and clamp the sample tube 18 under the action of the torsion spring 23, thus fixing the sample tube 18 and preventing it from colliding with the side wall of the mounting cylinder 24 due to external force. This further fixes and protects the sample tube 18.
[0029] Please see Figure 1 and Figure 2 A lid 1 is rotatably mounted on the housing 14, and a latch 2 connects the housing 14 and the lid 1. A pull ring 15 is installed on the lid 1. The lid 1 is used to seal and protect the housing 14, the latch 2 is used to close the lid 1, and the pull ring 15 facilitates the user's movement of the entire device.
[0030] The working principle of this utility model is as follows:
[0031] This device features a mounting base 12 within the housing 14. Multiple mounting cylinders 24 are located on the mounting base 12. The top of each mounting cylinder 24 is sealed via an extended tube 8 connected to a sealing cap 3. The sample tube 18 is placed inside the mounting cylinder 24. The primary shock-absorbing component 11 at the bottom, the secondary shock-absorbing component 7 at the top, and the fixing component 10 in the middle work simultaneously to secure and protect the sample tube 18, preventing impacts from sudden changes in external forces on the soil sample. This device significantly improves the protection and shock absorption of soil samples, avoiding the problem of increased disturbance to the soil sample caused by various shaking during transportation, thus ensuring the accuracy of soil sample testing.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention.
