Description

Technical Field

[0001] This utility model belongs to the field of sampling and testing technology, specifically relating to a sampling device and a bone oil testing and sampling system using the device. Background Technology

[0002] Currently, bovine bones are used as raw materials for producing bone granules and bone oil. The resulting bone oil often requires sampling and testing. Traditional tools, such as glass pipettes, single-mouth sampling tubes, or simple metal spoons, are commonly used for sampling. While these methods can achieve the desired bone oil sample collection, they have the following drawbacks: First, due to its density characteristics and storage conditions, bone oil tends to stratify within the storage container. A small amount of impurities may float on the surface, while trace amounts of solid residue may accumulate at the bottom. Traditional tools can only achieve single-point sampling, making it difficult to obtain representative samples covering different depths and locations. This can easily lead to discrepancies between the test results and the actual quality of the bone oil, resulting in misjudgments of the raw material's quality. Second, bone oil residue often remains on the outer wall of the tool after sampling and is removed along with the sampling device. This residue tends to drip after removal, causing waste of raw materials and increasing subsequent cleaning costs. Utility Model Content

[0003] To address the problems existing in the prior art, a sampling device and a bone oil detection and sampling system using the device are proposed.

[0004] The technical solution to the technical problem solved by this utility model is as follows: On the one hand, a sampling device is proposed, including a housing, a sampling tube is slidably connected inside the housing, and the top of the sampling tube extends out of the housing and is connected to a pressure plate; several storage slots are vertically opened on the sampling tube; several through holes are opened on the side wall of the housing, and the through holes and storage slots are staggered. Pressing the pressure plate to move the sampling tube down can connect the through holes and storage slots to achieve oil inlet.

[0005] Preferably, a gripping plate is connected to the top of the housing, and a first spring is connected between the gripping plate and the pressure plate; a boss is also formed on the outer wall of the sampling tube, and the boss presses against the bottom of the gripping plate to limit the sampling tube.

[0006] Preferably, a limiting component is also connected between the sampling tube and the housing to limit the sampling tube during sampling.

[0007] Preferably, the limiting component includes a bracket connected to the top of the housing, with a square hole laterally opened on the bracket; a limiting rod is also rotatably connected to the top of the pressure plate, and the limiting rod passes through the square hole; a square block is connected to the upper part of the limiting rod, and when the square block is rotated to the horizontal position, it can pass through the square hole, and when the square block is rotated to the vertical position, it can press down on the limiting rod and lock it at the bottom of the bracket.

[0008] Preferably, the limiting component includes a vertical rod fixed to the bottom of the sampling tube, with an inverted trapezoidal first limiting block connected to the bottom of the vertical rod, and a regular trapezoidal second limiting block slidably connected to the vertical rod; a horizontal rod is slidably connected to the side wall of the housing, and the horizontal rod can slide laterally on the housing; a limiting plate is connected to the outer end of the horizontal rod, and a locking block is connected to the inner end of the horizontal rod, with a beveled surface on the locking block, which can be pressed outward by the first limiting block; a second spring is also sleeved on the horizontal rod, with the two ends of the second spring connected to the inner wall of the housing and the locking block, respectively.

[0009] Preferably, a third spring is also fitted on the vertical rod, with one end of the third spring connected to the bottom of the sampling tube and the other end connected to the second limiting block.

[0010] On the other hand, a bone oil testing and sampling system is also proposed, including the sampling device mentioned above, which can be inserted into the oil storage tank for sampling; the sampling device is covered with a baffle, which can slide along the outer wall of the sampling device; the baffle is placed on the mouth of the oil storage tank to block the mouth; the bottom of the baffle is connected to an oil collecting ring, which surrounds the sampling device and is placed inside the mouth of the tank when the baffle is placed on the mouth of the tank.

[0011] Preferably, the baffle includes two arc plates, the inner sides of the two arc plates are fitted together to form a baffle, and the two ends of the connecting hinge are respectively connected to the bottom of the two arc plates to realize relative rotation of the two arc plates; the bottom of the baffle is concave to form a groove, and the oil collecting ring is set in the groove to form an oil draining space.

[0012] Preferably, the oil collecting ring is an inverted trapezoidal shape that is wider at the top and narrower at the bottom, so that the oil dripping down the inner wall of the baffle can flow down the oil collecting ring, collect, and drip back into the oil storage tank.

[0013] Preferably, the inner side of the arc plate is also connected to a pull rope for easy retraction.

[0014] Compared with existing technologies, the above technical solution has the following advantages or beneficial effects: 1. The sampling tube of this utility model is vertically provided with several storage slots, which are misaligned with the through holes on the side wall of the shell. Pressing the pressure plate allows bone oil at different depths to enter the storage slots simultaneously, enabling the acquisition of bone oil samples from different positions in the oil storage tank at one time. This solves the problem of deviation between the test results and the actual quality caused by traditional single-point sampling, and improves the representativeness of the sampling and the accuracy of the test.

[0015] 2. The baffle and the oil collecting ring of this utility model form an oil-draining structure. The bone oil remaining on the outer wall of the sampling device flows to the oil collecting ring under the obstruction of the baffle.

[0016] 3. The sampling device of this utility model sampling system achieves rapid triggering and resetting of the sampling action through a gripping plate, a pressure plate and a first spring. The boss and the limiting component form a double limiting structure, which can accurately control the movement stroke of the sampling tube and ensure precise docking between the through hole and the storage tank. At the same time, the baffle adopts a foldable double arc plate design, which, together with the pull rope, makes it easy to open, close and store, adapting to the sampling needs of oil storage tanks of different specifications and improving the convenience of sampling operation.

[0028] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1: Please see Figures 1-2To address the difficulty of achieving multi-point sampling at different depths in liquid sampling, this embodiment proposes a sampling device. This device can be applied not only to the detection and sampling of bone oil but also to the detection and sampling of liquids such as gasoline and pharmaceutical solutions. It includes a cylindrical shell 1, which can be made of stainless steel. The shell 1 is hollow with a smooth inner wall. A sampling tube 2 is slidably connected inside the shell 1. The outer wall of the sampling tube 2 is tightly fitted to the inner wall of the shell 1 to achieve a sealed fit. The top of the sampling tube 2 extends vertically out of the shell 1 and is fixedly connected to a pressure plate 3. The diameter of the pressure plate 3 is larger than the diameter of the sampling tube 2 and facilitates manual pressing operation. Several vertically spaced openings are provided on the side wall of the sampling tube 2. The dry storage tank 21 has an opening facing the side wall of the shell 1 and a uniform depth. There is an equal distance between adjacent storage tanks 21. Several through holes 101 are opened at different height positions on the side wall of the shell 1. The number and diameter of the through holes 101 match the storage tanks 21 one by one. In the initial state, the through holes 101 and the storage tanks 21 are staggered, that is, the opening of the storage tank 21 is blocked by the side wall of the shell 1. When the pressure plate 3 is pressed to move the sampling tube 2 downward along the axial direction of the shell 1, it can drive the storage tanks 21 to move downward synchronously until the through holes 101 and the storage tanks 21 are precisely aligned and connected. At this time, the external bone oil can flow into the storage tanks 21 through the through holes 101 to achieve oil entry.

[0030] By using the sliding seal between the sampling tube 2 and the housing 1, combined with the staggered design of the through hole 101 and the storage tank 21, oil can be effectively blocked from entering the storage tank 21 when no sample is being taken, thus avoiding sample contamination or premature leakage. The setting of multiple storage tanks 21 and through holes 101 can obtain multiple samples of different heights at one time, meeting the needs of comparative testing. The press-driven operation is simple and direct, and the sampling action can be achieved without complex adjustment.

[0031] Example 2: Continue reading Figures 1-2 Based on Embodiment 1, in this embodiment, a gripping plate 4 is fixedly connected to the edge of the top of the housing 1. The gripping plate 4 has a U-shaped or annular structure. The inner side of the gripping plate 4 is fixedly attached to the outer wall of the housing 1. A first spring 5 is connected between the gripping plate 4 and the pressure plate 3. The first spring 5 is sleeved on the outside of the sampling tube 2. In its natural state, the first spring 5 is in a slightly stretched state, providing an upward restoring force for the pressure plate 3. The upper part of the outer wall of the sampling tube 2 also narrows inward to form an annular protrusion 22. The diameter of the protrusion 22 is larger than the diameter of the main body of the sampling tube 2 and smaller than the inner diameter of the housing 1. The top surface of the protrusion 22 can push upward against the bottom of the gripping plate 4 to limit the upward movement of the sampling tube 2 and prevent the sampling tube 2 from detaching from the top of the housing 1.

[0032] The gripper 4 is designed to provide a force point for the holding device, making it easy to accurately insert or remove the sampling device into the oil storage tank 10, thus improving operational stability. The first spring 5 can automatically drive the sampling tube 2 to reset after pressing the sampling, eliminating the need to manually lift the pressure plate 3 and simplifying the operation process. The limiting function of the boss 22 can prevent the sampling tube 2 from moving too high and causing the structure to detach, thus enhancing the structural safety and service life of the device.

[0033] Example 3: Please see Figures 1-9 Based on the above embodiments, this embodiment proposes a bone oil detection sampling system, including the above-mentioned sampling device. The sampling device can be guided into the oil storage tank 10 by a conical guide head 7 and inserted vertically for sampling. A baffle 8 is sleeved on the outer side of the housing 1 of the sampling device. The baffle 8 has a circular structure and a through hole 101 adapted to the outer wall of the housing 1 in its middle. The baffle 8 can slide up and down along the outer wall of the housing 1 of the sampling device. When the sampling device is inserted into the oil storage tank 10, the baffle 8 can be placed on the edge of the opening 11 of the oil storage tank 10. Its edge fits against the inner wall of the opening 11 to block the opening 11. An oil collecting ring 83 is fixedly connected to the bottom edge of the baffle 8. The oil collecting ring 83 has an annular structure and surrounds the outer side of the housing 1 of the sampling device. When the baffle 8 is placed on the opening 11, the oil collecting ring 83 is placed inside the opening 11, and its inner wall leaves a gap with the outer wall of the housing 1.

[0034] The baffle 8 can cover the opening 11 of the oil storage tank 10, which not only prevents external impurities from falling into the tank and contaminating the bone oil during the sampling process, but also prevents the bone oil inside from being carried out of the oil storage tank 10 when the sampling device is pulled out, thus avoiding waste; the oil collecting ring 83 can collect the oil flowing down the shell 1 when the sampling device is inserted and removed, preventing the oil from spilling outside the tank and causing waste and environmental pollution; the baffle 8 can slide to adjust its position to adapt to oil storage tanks 10 of different heights or different sampling depths.

[0035] Example 4: Continue reading Figures 1-9The baffle 8 includes two symmetrical arc plates 84. When the inner edges of the two arc plates 84 are fitted together, they can be spliced ​​to form a complete circular baffle 8. The bottom edges of the two arc plates 84 are respectively fixedly connected to the two ends of the hinge 81, allowing the two arc plates 84 to rotate relative to each other around the axis of the hinge 81. The bottom of the baffle 8 is recessed inward to form an annular groove 82. An oil collecting ring 83 is fixedly set in the groove 82. The depth of the groove 82 is adapted to the height of the oil collecting ring 83, forming a closed oil-draining space between the groove 82 and the oil collecting ring 83. The two arc plates 84 are connected by the hinge 81 to open and close, making it easy to store the baffle 8. At the same time, the inner side of the arc plate 84 is also connected to a pull rope 9 for easy folding. After sampling, the baffle 8 can be lifted directly by pulling the rope 9, which facilitates the use of the baffle 8. During the lifting process, the lower oil-blocking surface will automatically align to prevent the oily side from rubbing against people or the environment, avoiding cleaning.

[0036] Finally, the oil collecting ring 83 is an inverted trapezoidal shape, wider at the top and narrower at the bottom. Oil dripping down the inner wall of the baffle 8 can flow down the oil collecting ring 83, collect, and drip back into the oil storage tank 10. The combination of the inverted trapezoidal structure and the smooth, sloping inner wall accelerates the flow and convergence of oil, preventing oil residue in the oil collecting ring 83. The design of being wider at the top and narrower at the bottom expands the oil collection range, ensuring that all oil flowing down the shell 1 is collected. At the same time, the narrow opening at the bottom guides the oil to drip precisely back into the oil storage tank 10, further reducing oil waste.

[0037] Example 5: Continue reading Figures 1-4 In Example 2, sampling requires continuous downward pressure on the sampling tube 2, which is quite cumbersome. Therefore, this example further optimizes the process based on Example 2. A limiting component 6 is provided between the sampling tube and the housing. In this embodiment, the limiting component 6 includes a bracket 69, which is connected to the top of the housing 1. A square hole 612 is opened laterally on the bracket 69. A limiting rod 610 is rotatably connected to the top of the pressure plate 3, and the limiting rod 610 passes through the square hole 612. A square block 611 is connected to the upper part of the limiting rod 610. When the square block 611 is rotated to the horizontal position, it can pass through the square hole 612. When the square block 611 is rotated to the vertical position, it presses down on the limiting rod 610 and can lock it at the bottom of the bracket 69. In use, after pressing down the pressure plate 3 to the designated position, the limiting rod 610 is rotated to rotate the square block 611 from the horizontal to the vertical position, which can lock it at the bottom of the bracket 69 to achieve limiting, which facilitates the sampling of bone oil.

[0038] Example 6: Continue reading Figures 1-4This embodiment proposes another limiting component 6, which includes a vertical rod 61 fixed vertically to the bottom of the sampling tube 2. The vertical rod 61 extends along the axis of the sampling tube 2. An inverted trapezoidal first limiting block 62 is integrally connected to the bottom of the vertical rod 61. The cross-section of the first limiting block 62 is a trapezoidal structure that is narrower at the top and wider at the bottom. A regular trapezoidal second limiting block 63 is slidably connected to the vertical rod 61. The cross-section of the second limiting block 63 is a trapezoidal structure that is wider at the top and narrower at the bottom, and its inclined surface is adapted to the inclined surface of the first limiting block 62. A sliding hole is laterally opened on the side wall of the lower part of the housing 1. A cross rod 65 is slidably connected in the sliding hole. The cross rod 65 and the sliding hole are sealed together. The cross rod 65 can slide laterally along the radial direction of the housing 1. The outer end of the cross rod 65 A limiting plate 66 extends out of the housing 1 and is fixedly connected to it. The diameter of the limiting plate 66 is larger than the diameter of the sliding hole to prevent the crossbar 65 from fully extending into the housing 1. The inner end of the crossbar 65 is located inside the housing 1 and is fixedly connected to a locking block 67. The locking block 67 has a beveled surface on the side facing the vertical bar 61. The inclination angle of the beveled surface is the same as the inclination angle of the first limiting block 62. When the sampling tube 2 moves down and drives the first limiting block 62 to move, the inclination of the first limiting block 62 can squeeze the beveled surface of the locking block 67 and push the locking block 67 to move outward. A second spring 68 is also sleeved on the crossbar 65. The second spring 68 is located between the inner wall of the housing 1 and the locking block 67. In its natural state, the second spring 68 is in a compressed state and can push the locking block 67 to extend inward. By using the inclined surfaces of the first limiting block 62 and the locking block 67, the sampling tube 2 can be automatically triggered to limit the movement when it moves downward. Under the action of the second spring 68, the locking block 67 can lock the first limiting block 62, thereby positioning the sampling tube 2. In this way, the sampling tube 2 can be locked so that the liquid to be sampled can flow into the storage tank 21 through the through hole 101, making sampling more convenient. After sampling is completed, the sampling tube 2 is pressed down again, causing the locking block 67 to continue to move upward relative to the vertical rod 61. After passing the second limiting block 63, the pressure plate 3 is released, and the sampling tube 2 can be closed under the action of the first spring 5, thus completing the sampling.

[0039] In addition, a third spring 64 is also fitted on the vertical rod 61. One end of the third spring 64 is connected to the bottom of the sampling tube 2, and the other end is connected to the second limiting block 63. The third spring 64 can drive the second limiting block 63 to automatically reset to the initial position with a certain distance from the first limiting block 62, so that it can be easily reset and prevent the first limiting block 62 from sticking to the second limiting block 63 and failing to perform the limiting.

[0040] Finally, in this embodiment, the bottom of the housing 1 is also recessed to form a conical guide head 7 to reduce the agitation of the sampled liquid.

[0041] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
