Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] A preferred embodiment of a sampling device for oil analysis provided by the present invention is as Figures 1 to 5 shown: A sampling device for oil analysis includes a cylinder 1. A rubber pad 2 is attached to the inside of the cylinder 1. A pull rod 3 is fixedly connected to the top of the rubber pad 2. A collection mechanism 4 is arranged below the cylinder 1. The collection mechanism 4 includes a receiving component 41 and a blocking component 42.

[0030] In this embodiment, the receiving component 41 includes a connecting ring 411, a storage cylinder 412, a connecting plate 413, a spring 414, and a cover plate 415. By setting the receiving component 41, the adsorbed oil can be stored.

[0031] In this embodiment, the connecting ring 411 is threadedly connected to the surface of the cylinder 1. The storage cylinder 412 is fixedly connected to the bottom of the connecting ring 411. Connecting plates 413 are fixedly connected to both sides of the storage cylinder 412. Springs 414 are fixedly connected to the surfaces of the two connecting plates 413. The tails of the two springs 414 are fixedly connected to a cover plate 415 that is slidably connected to the connecting plate 413.

[0032] In this embodiment, the blocking component 42 includes a threaded rod 421, a connecting rod 422, a rubber ring 423, a control plate 424, a sliding rod 425, a stress plate 426, a sealing plate 427, a telescopic rod 428, and a sealing ring 429. By setting the blocking component 42, the bottom of the storage cylinder 412 can be quickly sealed to prevent oil leakage.

[0033] In this embodiment, the threaded rod 421 is threadedly connected to the side of the storage cylinder 412. The tail of the threaded rod 421 is rotatably connected to a connecting rod 422 that is slidably connected to the inside of the storage cylinder 412. A rubber ring 423 fixedly connected to the storage cylinder 412 is attached to the surface of the connecting rod 422. The tail of the connecting rod 422 is fixedly connected to a control plate 424. A sliding rod 425 is fixedly connected to the surface of the control plate 424. A stress plate 426 is slidably connected to the surface of the sliding rod 425. A sealing plate 427 that is embedded in the storage cylinder 412 and closely fits with it is fixedly connected to the bottom of the stress plate 426. A sealing ring 429 fixedly connected to the storage cylinder 412 is attached to the bottom of the sealing plate 427. A telescopic rod 428 fixedly connected to the storage cylinder 412 is fixedly connected to the top of the sealing plate 427.

[0034] In this embodiment, the cylinder 1 and the storage cylinder 412 are designed to be interconnected. The top of the storage cylinder 412 is enclosed by two sets of cover plates 415, which facilitates sucking up the oil inside the oil barrel when pulling the pull rod 3.

[0035] In this embodiment, the connecting rod 422 and the cylinder 1 are in a tightly fitting state. The force-bearing plate 426 forms a left-right sliding structure through the connecting rod 422. When the threaded rod 421 is rotated, during its rotation, the connecting rod 422 is controlled to slide inward, and the sliding rod 425 moves together with it.

[0036] In this embodiment, the sliding rod 425 is embedded in the internal inclined groove of the force-bearing plate 426 and is slidably connected to it. The sealing plate 427 forms a lifting structure through the sliding rod 425 and under the action of the telescopic rod 428. When the sliding rod 425 moves, it slides along the internal inclined groove of the force-bearing plate 426 and exerts an upward thrust on the force-bearing plate 426. Under the limiting action of the telescopic rod 428, the force-bearing plate 426 drives the sealing plate 427 to move horizontally upward.

[0037] Embodiment 2

[0038] Based on Embodiment 1, a preferred embodiment of the sampling device for oil product analysis provided by the present utility model is as Figures 1 to 5 shown: In this embodiment, a baffle 5 is fixedly connected to the surface of the storage cylinder 412. Below the baffle 5, an inlet 6 threadedly connected to the bottom of the storage cylinder 412 is provided, and a rubber hose 7 is sleeved on the surface of the inlet 6.

[0039] In this embodiment, a detachable structure is formed between the inlet 6 and the storage cylinder 412. The rubber hose 7 is tightly attached to the surface of the inlet 6. Through the detachable design of the storage cylinder 412, it is convenient to transport the sampled oil without injecting the sucked oil back into the oil-containing container for transportation again, and at the same time, it is convenient to clean the inside of the storage cylinder 412 for storing oil.

[0040] The working principle and usage process of the present utility model: First, when sampling oil is required, the rubber hose 7 is sleeved on the inlet 6. After checking that the sleeve is firm, the rubber hose 7 is inserted into the oil-containing container. Then, the threaded rod 421 is rotated. During its rotation, the connecting rod 422 is controlled to slide inward, and the sliding rod 425 moves together with it. When the sliding rod 425 moves, it slides along the internal inclined groove of the force-bearing plate 426 and exerts an upward thrust on the force-bearing plate 426. Under the limiting action of the telescopic rod 428, the force-bearing plate 426 drives the sealing plate 427 to move horizontally upward to open the bottom of the storage cylinder 412. Then, the pull rod 3 is pulled upward to control the rubber pad 2 to rise inside the cylinder 1. At this time, the oil inside the oil barrel will be sucked into the inside of the storage cylinder 412 through the rubber hose 7.

[0041] After the sampling is completed, the threaded rod 421 can be rotated again to control the connecting rod 422 to slide sideways, and thereby drive the sealing plate 427 to descend through the slide rod 425 to closely fit with the sealing ring 429, so that the bottom of the storage cylinder 412 is closed. Then, the rubber hose 7 is taken out from the inside of the oil barrel, and the inlet 6 is disassembled from the bottom of the storage cylinder 412. Then, the connecting ring 411 is taken off from the cylinder 1. At this time, under the action of the spring 414, the two cover plates 415 will be controlled to approach each other to close the top of the storage cylinder 412. Through the detachable design of the storage cylinder 412, it is convenient to transport the sampled oil without injecting the sucked oil into the oil container again for transportation. At the same time, it is convenient to clean the inside of the storage cylinder 412 for storing oil. And by setting the baffle 5, when sampling, the baffle 5 can block the bottle mouth to prevent dust from entering the oil barrel.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
