[0026] This utility model proposes a universal core box with multiple specifications.

[0027] As attached Figure 1 -Appendix Figure 4 As shown, the universal core box for multiple specifications proposed in this utility model includes a box body 1. The box body 1 is provided with a first partition 11, which divides the interior of the box body 1 into multiple sub-spaces. Each sub-space is detachably provided with an independent groove 3. The groove 3 has an elongated groove with an arc-shaped cross-section. Each elongated groove has a different inner diameter to accommodate cores of different sizes. The outer walls of the groove 3 on both sides abut against the inner walls of the sub-spaces. A clamping component is provided on the inner wall of one end of the groove 3. The clamping component includes a pressure plate 31 and an elastic rod 32. One end of the elastic rod 32 is connected to the inner wall of one end of the groove 3, and the other end of the elastic rod 32 is connected to the pressure plate 31. The pressure plate 31 is used to abut against one end of the rock core placed in the long groove.

[0028] This invention features a simple structure. By configuring detachable tanks 3 with various inner diameters within a standard box 1, it perfectly solves the problem in existing technologies where a single core box can only store cores of a single specification. Users no longer need to equip different core boxes for cores of different diameters, significantly reducing equipment procurement costs and warehouse management complexity. Furthermore, the tanks 3 can be replaced according to different situations.

[0029] Different sizes of rock cores can be mixed and stored in the same box 1 for transportation and storage, avoiding the waste of space inside the box caused by mismatched rock core sizes, and greatly improving space utilization efficiency and the number of rock cores transported in a single trip.

[0030] By setting up a special clamping component, the rock core placed in the tank 3 can be fixed at the end, effectively preventing the rock core from rolling and colliding in the box, which would cause damage and loss of geological information, and ensuring the integrity and authenticity of the rock core sample.

[0031] Since each trough 3 is independent and detachable, the trough 3 can be replaced according to actual needs, so that the inner diameter of the long troughs in the trough 3 is the same, so that the core box can carry cores of the same diameter or cores of different diameters.

[0032] Furthermore, the pressure plate 31 is perpendicular to the elastic rod 32.

[0033] The elastic rod 32 continuously provides clamping force towards the rock core, ensuring that the pressure plate 31 remains firmly attached to the end of the rock core. This design automatically adapts to minor displacements caused by slight differences in rock core length or vehicle bumps, maintaining a reliable fixation effect that is more effective than rigid fixation structures.

[0034] Moreover, the combination structure of the pressure plate 31 and the elastic rod 32 is simple, with few parts, low manufacturing cost, and is not prone to failure, ensuring the long-term stable operation of the clamping function.

[0035] Furthermore, the elastic rod 32 includes an outer rod, an inner rod, and an elastic element. The outer rod is a hollow tubular structure with one open end. The inner rod is slidably embedded in the inner cavity of the outer rod and can extend or retract from the open end of the outer rod. The elastic element is placed in the inner cavity of the outer rod, and its two ends abut against the bottom of the outer rod and the inner end of the inner rod, respectively. The elastic element is always in a compressed state.

[0036] In addition, the elastic element is a spring.

[0037] When a spring is used as an elastic element, it can provide a linear, uniform and controllable elastic clamping force, which can not only firmly fix the rock core, but also avoid the pressure damage to the end of the rock core that may be caused by excessive pressure.

[0038] In addition, a heightening frame 2 is detachably provided on the top of the box body 1; a second partition 21 is provided inside the heightening frame 2; the number of the second partition 21 and the first partition 11 are the same, and the second partition 21 and the first partition 11 correspond one-to-one; the second partition 21 is located above the corresponding first partition 11, and the position of the second partition 21 extending in the same direction as the corresponding first partition 11 corresponds one-to-one with the position of the first partition 11 in the vertical direction.

[0039] By adding the heightening frame 2, the vertical space of the core box can be flexibly increased to meet the storage needs of the core, greatly improving the product's applicability and flexibility.

[0040] In addition, the upper part of the two side walls of the box body 1 is provided with a drain outlet 12, and the bottom of the raised frame 2 is provided with a mounting protrusion 22. The shape of the mounting protrusion 22 is adapted to the drain outlet 12, so that when the raised frame 2 is installed on the box body 1, the mounting protrusion 22 is embedded in the drain outlet 12.

[0041] In addition, the drain outlet 12 is vertically arranged and penetrates through the box body 1, and the end of the trough body 3 is provided with a drain hole 33, and the drain outlet 12 is connected to the drain hole 33.

[0042] The mounting protrusion, in conjunction with the drain outlet, not only facilitates drainage but also acts as a positioning pin, ensuring that the raised frame can only be installed onto the box in the correct orientation. This enables quick and precise assembly, effectively preventing reverse or incorrect installation. Furthermore, the positioning is achieved using the structure of the drain outlet itself, eliminating the need for additional complex positioning components. This results in a more compact and concise overall structure, reducing mold complexity and production costs.

[0043] In addition, handles 5 are provided on both sides of the box 1; the handles greatly facilitate workers to lift and move the core box.

[0044] In addition, a core plate 6 is provided on the front of the box 1. The core plate 6 is used to record the core information inside the box 1. The core plate can clearly and intuitively record key information such as the core number, well number, depth, and core sampling date inside the box.

[0045] In addition, a scale 4 is provided on the upper surface of the raised frame 2, and the side wall of the scale 4 is parallel to the outer wall of the groove 3.

[0046] Staff can quickly read and record the length of the rock core directly using a ruler without moving the core, making the operation extremely simple and greatly improving work efficiency.

[0047] The scale sidewall is parallel to the outer wall of the tank, ensuring that the measurement reference is parallel to the core axis, thus guaranteeing the accuracy of the measurement results and providing reliable data support for geological analysis.

[0048] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
