Description

Technical Field

[0001] This utility model belongs to the field of geotechnical engineering investigation and sampling, and specifically relates to a geotechnical investigation and sampling box. Background Technology

[0002] In the field of geotechnical engineering, geotechnical sampling boxes play a crucial role. They are used to properly store geotechnical samples, providing raw materials for subsequent experimental analysis, geological condition assessment, and other work. By studying the geotechnical samples inside the box, important information such as stratigraphic structure and geotechnical properties can be accurately obtained, thus providing data support for the design and construction of various projects.

[0003] Currently, the core component of common geotechnical sampling kits is the soil sample box, which is the main body for holding geotechnical samples. A label is usually affixed to the lid of the soil sample box, detailing key information such as the collection location, depth, time, and number of the geotechnical sample. This label is crucial for sample identification and traceability. To protect the label, it is commonly wrapped with plastic tape. The plastic tape maintains the integrity and readability of the label by isolating it from air, moisture, and physical friction.

[0004] However, in actual long-term use, after prolonged storage, the adhesive properties of plastic tape will gradually weaken. Once the adhesive properties are lost, the tape is prone to loosening, lifting, or even falling off, making it unable to maintain a tight fit to the label and thus failing to provide effective protection. Utility Model Content

[0005] This invention addresses the problem that existing plastic tapes cannot protect labels for a long time due to adhesive failure. It provides a geotechnical exploration sampling box that effectively protects labels through an independent label box, maintaining the integrity of the labels for a long period of time.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: a soil sampling box, including a soil sample box, with a sample box top cover and a sample box bottom cover installed at both ends of the soil sample box, and a label box installed on the outer top of the sample box top cover. The label box includes a base and a lid. The bottom of the base is fixedly connected to the outer top of the sample box top cover, and the top of the base is provided with an installation groove. A label is placed in the installation groove. The lid is located above the installation groove, and the lid and the base are rotatably connected. The lid is provided with a locking mechanism, which can lock the lid on the base and seal the installation groove.

[0007] In this technical solution, a top cover and a bottom cover are respectively installed at both ends of the soil sample box. A label box is installed on the outer top of the top cover. The label box includes a base and a lid. The bottom of the base is fixedly connected to the outer top of the top cover. The top of the base has a mounting groove for storing labels. The lid is located above the mounting groove. The lid and the base are rotatably connected. The lid has a locking mechanism that can lock the lid onto the base and seal the mounting groove. By encapsulating the labels in the label box, the labels are protected. Therefore, this sampling box effectively protects the labels through an independent label box, maintaining the integrity of the labels for a long time.

[0008] Furthermore, two bushings are fixed to the top of the base, and the two bushings are coaxially arranged. A hinge shaft is provided between the two bushings, and the outer surface of the hinge shaft is fixedly connected to the side of the lid. The hinge shaft is coaxial with the two bushings, and a pin is installed at each end of the hinge shaft, which is inserted into the inner hole of the corresponding bushing. Ensuring that the two bushings and the hinge shaft are coaxial effectively avoids jamming or wear caused by assembly deviations, ensuring even force distribution when the lid rotates and reducing component wear. The pins at both ends of the hinge shaft are inserted into the inner holes of the bushings, forming an axial limit, which prevents the hinge shaft from slipping out of the bushings during rotation, especially suitable for scenarios requiring frequent opening and closing. The bushings serve as a fixed base, and the hinge shaft and lid are fixed together, achieving a rotatable connection through the pins. The structure is simple and has low frictional resistance, allowing the lid to open and close easily and conveniently.

[0009] Furthermore, stepped holes are provided on the end faces of both ends of the hinge shaft. Each stepped hole includes an inner receiving section and an outer guide section. The centerlines of the receiving section and the guide section coincide, and the inner diameter of the receiving section is larger than that of the guide section. A stop block is provided within the receiving section, with the outer diameter of the stop block being the same as the inner diameter of the receiving section. A limit spring is provided between the stop block and the bottom of the stepped hole. One end of the limit spring is fixedly connected to the bottom of the stepped hole, and the other end is fixedly connected to one end face of the stop block. The other end face of the stop block is fixedly connected to one end of a pin. The other end of the pin passes through the guide section and is inserted into the inner hole of the bushing. The stepped design of the receiving and guide sections, combined with the limit spring and the stop block, gives the pin an elastic telescopic function. Axial retraction can be achieved by pressing the pin without additional tools, facilitating the quick assembly or separation of the hinge shaft and the bushing. Simultaneously, the restoring force of the limit spring ensures that the pin is stably inserted into the bushing hole. The matching design of the inner diameter of the receiving section and the diameter of the stop block not only provides sliding space for the stop block, but also prevents the stop block from shifting through radial constraint, ensuring the coaxiality of the pin during extension and retraction; the stepped surface of the stepped hole can limit the maximum extension distance of the stop block, preventing the pin from detaching from the guide section due to excessive extension of the limit spring force, forming a mechanical self-limiting and improving the structural reliability.

[0010] Furthermore, a sealing ring is fixed to the surface corresponding to the mounting groove on the lid, and the shape of the sealing ring is adapted to the mounting groove. This matching shape allows the sealing ring to fit tightly against the edge of the mounting groove when the lid is closed, filling any tiny gaps and effectively preventing external dust, moisture, oil, and other impurities from entering the mounting groove. This prevents the label from being contaminated, wetted, or worn, protecting the clarity and integrity of the label information. The sealing ring itself has a certain degree of elasticity; when the lid is closed, it is subjected to moderate compression, and the resulting rebound force ensures a tighter fit between the lid and the base, reducing loosening of the lid due to vibration or minor impacts, further solidifying the seal. This makes it particularly suitable for various environmental scenarios that soil sample boxes may encounter, such as outdoor and laboratory environments.

[0011] Furthermore, the top edge of the mounting groove is chamfered. The inclined transition surface formed by the chamfer can guide and correct the sealing ring during the closing of the lid. Even if the sealing ring is slightly misaligned during assembly or use, the beveled surface of the chamfer will guide it to the corresponding position on the edge of the mounting groove, ensuring a precise fit between the sealing ring and the mounting groove, and avoiding sealing failure due to misalignment. This is especially suitable for scenarios where the dimensions of the sealing ring and the mounting groove are precisely matched.

[0012] Furthermore, the locking mechanism includes a locking plate and a connecting plate. The locking plate is fixed to the side of the base and has a locking groove. The connecting plate is fixed to the side of the lid corresponding to the locking plate and has a connecting groove. A pull plate is installed in the connecting groove, and a locking spring is installed between the pull plate and the bottom of the connecting groove. One end of the locking spring is fixedly connected to the bottom of the connecting groove, and the other end is fixedly connected to one side of the pull plate. A locking rod is fixed to the other side of the pull plate and can be inserted into the locking groove. This achieves convenient automatic locking. When the lid is closed, releasing the pull plate allows the spring force of the locking spring to directly drive the pull plate to insert the locking rod into the locking groove, completing the locking process without additional operation. The locking state is stable and reliable. The locking spring continuously applies tension to the pull plate, keeping the locking rod and locking groove tightly engaged. This effectively resists minor vibrations, collisions, and other external forces, preventing accidental opening of the lid and ensuring the label in the mounting groove remains in a stable and sealed state. The structure is simple and the operation is flexible. Pulling the pull plate compresses the locking spring, causing the locking rod to disengage from the locking slot and unlocking the device. The entire process requires no tools and is easy to operate manually. At the same time, the corresponding setting of the locking plate and the connecting plate, as well as the guiding nature of the rod slot, ensures smooth locking and unlocking actions and prevents jamming.

[0013] Furthermore, a pull ring is fixed to the pull plate. The pull ring, with its protruding ring structure, provides a stable grip or hook position for the fingers. Compared to directly pulling the pull plate, it is easier to apply pulling force, reducing slippage or uneven force during operation, making the unlocking process more effortless and efficient.

[0014] Furthermore, both the base and the lid are made of highly transparent plastic. This high transparency allows users to clearly see the contents of the label inside the mounting slot from the outside, enabling quick identification without frequent opening of the lid. This saves operation time and reduces issues such as wear on the sealing ring and the entry of impurities caused by repeated opening and closing, making it particularly suitable for scenarios requiring rapid label information retrieval.

[0015] As can be seen from the above technical solution, the advantages of this utility model are as follows: In this technical solution, the soil sample box is equipped with a top cover and a bottom cover at both ends, with a label box located on the outer top of the top cover. The label box consists of a base and a lid: the bottom of the base is fixedly connected to the outer top of the top cover, and its top has an mounting groove for storing labels; the lid is rotatably connected above the mounting groove and equipped with a locking mechanism to lock the lid onto the base, thus sealing the mounting groove. In summary, by encapsulating the labels inside the label box, not only is independent protection of the labels achieved, but the integrity of the labels can also be effectively maintained for a long time.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] A type of geotechnical sampling box, such as Figure 1 As shown, the sample box includes a soil sample container 1 for holding soil samples. The upper and lower ends of the soil sample container 1 are respectively fitted with an upper cover 2 and a lower cover 3. A label box 4 for placing sample information labels 431 is fixedly installed on the outer top of the upper cover 2. The label box 4 consists of a base 42 and a cover 41. The bottom of the base 42 is fixed to the outer top of the upper cover 2 by a heat-fusion connection. The top of the base 42 is recessed inward to form an mounting groove 43 for placing the label 431. The cover 41 is fitted onto the mounting groove 43, and the cover 41 and the base 42 are connected by a rotatable structure. The cover 41 is also equipped with a locking mechanism 5, which can stably lock the cover 41 onto the base 42 and seal the mounting groove 43.

[0025] In this specific embodiment, the soil sample box 1 is made of stainless steel and is a cylindrical structure with openings at both ends. The cylinder wall has a uniform thickness and a smooth inner wall to reduce disturbance to the soil and rock samples during sampling. The upper cover 2 and the lower cover 3 are also made of stainless steel. The upper cover 2 is a cylindrical structure with an open bottom and a sealed top, and its inner diameter matches the outer diameter of the upper end of the soil sample box 1. The lower cover 3 is a cylindrical structure with an open top and a sealed bottom, and its inner diameter matches the outer diameter of the lower end of the soil sample box 1. During assembly, the upper cover 2 is fitted and fixed to the outer upper end of the soil sample box 1 with an interference fit, and the lower cover 3 is fitted and fixed to the outer lower end of the soil sample box 1 with the same interference fit. The tight fit of the metal surfaces achieves a seal at both ends of the soil sample box 1.

[0026] like Figure 2-3 As shown in this specific embodiment, both the base 42 and the lid 41 of the label box 4 are made of highly transparent plastic material, possessing good light transmittance and impact resistance. The base 42 has an overall rectangular structure, with its length and width slightly larger than the specifications of the label 431, and its height is adapted to the thickness of the label 431 and the closing requirements of the lid 41. Two cylindrical bushings 421 are symmetrically fixed near the edge of the top of the base 42. Both bushings 421 are fixed to the top surface of the base 42 as a whole by heat fusion connection, and their axis lines are collinear. The inner hole of the bushing 421 is cylindrical with a uniform diameter. A cylindrical hinge shaft 411 is provided between the two bushings 421. The length of the hinge shaft 411 is adapted to the distance between the two bushings 421. Its outer circular surface is fixedly connected to one side of the cover 41 by heat fusion connection. The axis of the hinge shaft 411 is collinear with the axis of the two bushings 421. A cylindrical pin 412 is installed at each end of the hinge shaft 411. The outer diameter of the pin 412 is adapted to the inner diameter of the bushing 421. The ends of the two pins 412 away from the hinge shaft 411 are respectively inserted into the inner holes of the two bushings 421 to form a rotatable fit.

[0027] like Figure 4-5 As shown, stepped holes 413 are provided axially on the end faces of both ends of the hinge shaft 411. Each stepped hole 413 consists of two parts: a receiving section 4132 near the interior of the hinge shaft 411 and a guide section 4131 near the end of the hinge shaft 411. The centerlines of the receiving section 4132 and the guide section 4131 coincide, and the inner diameter of the receiving section 4132 is larger than the inner diameter of the guide section 4131. The junction of the two forms an annular stepped surface. A circular stop 414 is installed inside the receiving section 4132. The outer diameter of the stop 414 is equal to the inner diameter of the receiving section 4132, allowing it to slide freely along the axial direction of the receiving section 4132 without significant radial wobble. A cylindrical spiral limiting spring 415 is installed between the side of the stop 414 away from the stepped surface and the bottom of the receiving section 4132. One end of the limiting spring 415 is welded to the center of the bottom of the receiving section 4132, and the other end is welded to the center of the corresponding side of the stop 414. The center of the side of the stop 414 near the stepped surface is welded to one end of a pin 412. The other end of the pin 412 passes through the guide section 4131 axially and extends to the outside of the hinge shaft 411, finally inserting into the inner hole of the corresponding bushing 421.

[0028] A chamfer is machined around the top edge of the mounting groove 43 on the top of the base 42, continuously distributed along the outer perimeter of the mounting groove 43, connecting the top of the inner sidewall of the mounting groove 43 to the top surface of the base 42. On the side surface of the cover 41 facing the mounting groove 43, a sealing ring 416 is fixedly attached to the outer perimeter of the mounting groove 43. The sealing ring 416 is made of elastic material, with a rectangular cross-section. Its outer diameter matches the outer diameter of the mounting groove 43, and its inner diameter is slightly smaller than the inner diameter of the mounting groove 43. It is fixedly connected to the surface of the cover 41 by adhesive bonding.

[0029] In this specific embodiment, the locking mechanism 5 consists of a locking plate 51 and a connecting plate 52. The locking plate 51 is a rectangular plate structure, fixed to the side of the base 42 away from the hinge axis 411 by heat fusion. A rectangular locking groove 511 is formed in the middle of the locking plate 51 along the thickness direction, and the depth of the groove is adapted to the length of the locking rod 55. The connecting plate 52 is also a rectangular plate structure, fixed to the side of the cover 41 corresponding to the locking plate 51 by heat fusion. A rectangular connecting groove 521 is formed in the middle of the connecting plate 52 along the thickness direction. The depth of the connecting groove 521 is adapted to the thickness of the pull plate 53, and the width is slightly larger than the width of the pull plate 53. A pull plate 53, adapted to the shape of the groove, is installed inside the connecting groove 521. The pull plate 53 can slide freely along the axial direction of the connecting groove 521. A cylindrical spiral locking spring 54 is installed between the side of the pull plate 53 away from the locking plate 51 and the bottom of the connecting groove 521. One end of the locking spring 54 is welded to the center of the bottom of the connecting groove 521, and the other end is welded to the center of the corresponding side of the pull plate 53. A locking rod 55 is welded to the center of the side of the pull plate 53 near the locking plate 51. The locking rod 55 can be inserted into the locking groove 511. In addition, a circular pull ring 56 is welded to the middle of the side of the pull plate 53 away from the locking rod 55 for easy finger hooking operation.

[0030] The specific usage process is as follows: First, place the completed label 431 flat into the mounting groove 43 at the top of the base 42, ensuring that the edge of the label 431 is not significantly offset from the inner wall of the mounting groove 43 and is completely flush with the bottom of the groove; then, hook the pull ring 56 with your finger and pull it away from the locking plate 51. The pull plate 53 slides outward along the axis of the connecting groove 521. At this time, the locking spring 54 between the pull plate 53 and the bottom of the connecting groove 521 is stretched synchronously, and the locking rod 55 moves outward with the pull plate 53, disengaging from the corresponding area of ​​the locking plate 51; next, with the hinge shaft 411 as the center of rotation, flip the box cover 41 towards the base 42 until the box cover 41 is completely fastened to the base 42. During this process, the sealing ring 416 on the inner side of the box cover 41 is embedded under the pressure. The chamfered transition surface of the top edge of the mounting groove 43 is gradually pressed into the mounting groove 43 as the cover 41 closes, and fits tightly with the outer periphery of the mounting groove 43 to form a sealed connection. Finally, the finger hooking the pull ring 56 is released, and the stretched locking spring 54 pulls the pull plate 53 back under the action of the return elastic force. The pull plate 53 drives the locking rod 55 to move synchronously towards the locking plate 51 until the locking rod 55 is accurately inserted into the locking groove 511 on the locking plate 51. At this time, the locking spring 54 still maintains a certain tension state, and continues to apply a pulling force to the pull plate 53 towards the bottom of the connecting groove 521, which is then transmitted to the locking rod 55 through the pull plate 53 to ensure that the locking rod 55 is always stably inserted into the locking groove 511, so as to achieve reliable locking between the cover 41 and the base 42.

[0031] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: In this specific embodiment, the soil sample box is equipped with a top cover and a bottom cover at both ends, with a label box located on the outer top of the top cover. The label box consists of a base and a lid: the bottom of the base is fixedly connected to the outer top of the top cover, and its top has an mounting groove for storing labels; the lid is mounted above the mounting groove via a rotatable connection and is equipped with a locking mechanism to lock the lid onto the base to achieve a seal on the mounting groove. In summary, by encapsulating the labels inside the label box, not only is independent protection of the labels achieved, but the integrity of the labels can also be effectively maintained for a long time.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
