Description

Technical Field

[0001] This utility model relates to the field of core box technology, and specifically to a core box equipped with a fixing device. Background Technology

[0002] A core box is a device used to store rock samples, designed to maintain their integrity so that scientists can analyze, study, and make judgments. Core boxes are widely used in fields such as geological exploration, mineral exploration, and mining.

[0003] When conducting columnar soil sampling, the sample must first be extracted from the soil using a sampling machine. Then, the plastic sample tube is manually cut open and placed into a core box. This involves holding the plastic sample tube with one hand while using a cutting tool to cut it open and place the sample into the core box. The sampler then collects the required sample from the core box. This method is prone to hand cuts, and some sample may fall to the ground after cutting, reducing the actual sample volume and failing to meet sampling technical requirements. Furthermore, the multi-step process makes the sample highly susceptible to contamination, leading to inaccurate subsequent test results. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figures 1-6 As shown, in one embodiment, a core box equipped with a fixing device includes: a box body 1, and fixing devices 2 are symmetrically arranged inside the box body 1.

[0030] For example, the core box is 1600mm long, 100-120mm wide, and 80-100mm deep. The box body 1 has equidistant grooves 11, and the fixing devices 2 are symmetrically arranged inside the grooves 11. This allows the plastic sampling tube to be securely fixed to the fixing devices 2. When cutting open the plastic sampling tube, the operation can be performed directly inside the core box without holding the tube by hand. The overall structure is simple and easy to operate, improving sampling efficiency while preventing sample spillage and effectively reducing the number of repeated samplings and the risk of being scratched by a cutting tool.

[0031] Please continue reading. Figures 1-6 In this embodiment, the fixing device 2 includes a clamping plate 21 and a base 22. The clamping plate 21 and the base 22 are detachably connected by a connector 23 and together form an annular fixing cavity, so that the plastic sampling tube can be firmly fixed in the fixing cavity and will not slip off.

[0032] Furthermore, the clamping plate 21 includes a first clamping part 211, which protrudes outward into a semi-circular groove 11. First fixing parts 212 are symmetrically arranged at both ends of the first clamping part 211, and each fixing part 212 has a through-hole 2121. Similarly, the base 22 includes a second clamping part 221, which is recessed inward into a semi-circular shape. Second fixing parts 222 are symmetrically arranged at both ends of the second clamping part 221, and each fixing part 222 has a through-hole 2221. Specifically, the first clamping part 211 of the clamping plate 21 and the second clamping part 221 of the base 22 have equal curvature, ensuring that the two semicircles are symmetrical. When closed, they form a standard elliptical fixing cavity, thus stably fixing the plastic sampling tube and enabling the cutting and sampling operation within the core box.

[0033] For example, the clamping plate 21 has a main body length of 100mm, a width of 40mm, and a thickness of 2mm. The radius of curvature of the first clamping part 211 is 80mm, and the center distance between the two sets of first fixing holes 2221 is 90mm, symmetrically and centrally arranged. Similarly, the base 22 has a main body length of 100mm, a width of 40mm, and a height of 40mm. The radius of curvature of the second clamping part 221 is 80mm, and the center distance between the two sets of second fixing holes 2222 is 90mm, symmetrically and centrally arranged.

[0034] Furthermore, the connector 23 is a screw 231, which passes through the connecting clamp 21 and the base 22. A nut 232 is installed on the top of the screw 231 to adjust the clamping tightness of the clamp 21 and the pressure on the plastic sampling tube. A washer 233 is installed at the bottom of the screw 231 to distribute the pressure of the screw 231 on the base 22 and prevent damage to the base 22 due to excessive local pressure. In use, the screw 231 with the washer 233 passes through the second fixing hole of the base 22 and the first fixing hole of the clamp 21 in sequence, and then the nut 232 is installed. The plastic sampling tube is then tightened by adjusting the nut 232.

[0035] Through the above technical solution, this application uses the screw 231 to connect the clamping plate 21 and the base 22 to form a fixed structure. When in use, the adjusting nut 232 is used to tighten the plastic sampling tube. The structure is simple and easy to operate. It can improve the sampling efficiency while avoiding sample spillage, effectively reducing the number of repeated samplings and the risk of being scratched by the knife.
