[0022] The cover body 2 is provided with an extraction mechanism, a connecting port 21 is opened on the cover body 2, a sealing plug 4 is arranged in the connecting port 21, and the sealing plug 4 can be sealed and connected with the connecting port 21 when it is inserted into the connecting port 21. The extraction mechanism comprises an airbag 5, an air pipe 6, a connecting ring 7 and a feeding pipe 8. The airbag 5 is fixedly connected and communicated with the top end of the air pipe 6, the connecting ring 7 can extend into the connecting port 21 and be sealed and connected with the connecting port 21, the bottom end of the air pipe 6 passes through the connecting ring 7 and is fixedly connected with the sealing plug 4, and an air hole 61 is arranged below the air pipe 6, a connected feeding pipe 8 is arranged on one side of the tank body 1, a second valve 16 is fixed on the feeding pipe 8, and a connected discharge head 9 is arranged at the outer end of the feeding pipe 8. When a small amount of lubricating oil needs to be extracted, the second valve 16 is opened and the airbag 5 is pressed several times, so that the air in the airbag 5 is pressed into the tank body 1 through the air hole 61, and the pressure difference between the inside and outside of the tank body 1 presses the lubricating oil into the feeding pipe 8 on one side and flows out through the discharge head 9.

[0023] A placement groove 121 for placing the air bag 5 is provided on the support frame 12, and a dust cover 17 is provided on the cover body 2. A hinged movable plate 171 is provided on one side of the dust cover 17. A through groove 172 for the air pipe 6 to pass through is opened on the top of the dust cover 17.

[0024] The working principle of the embodiment of the utility model is as follows: after the lubricating oil to be stored is poured into the tank body 1, the handle 14 is operated to rotate the push rod 13 to push the cover body 2 downward to cover the tank body 1, the raised portion 22 of the cover body 2 extends into the tank body 1, and the rubber ring 10 abuts against the inner wall of the tank body 1 to make it sealed, so that the lubricating oil in the tank body 1 is sealed and preserved, the sealing plug 4 is placed in the connecting port 21 and is sealedly connected to the connecting port 21, the dust cover 17 is placed on the cover plate 2, the connecting ring 7, the air pipe 6 below and the connecting port 21 are all placed in the dust cover 17 to avoid dust accumulation; when a small amount of sampling is needed, the fixing plate 173 and the movable plate 171 are opened, the air pipe 6 is moved out along the through groove 172, the dust cover 17 is removed, and the rubber ring 10 is pressed downward. The rubber plug 10 allows the rubber plug 10 to enter the tank body 1 through the connecting port 21, the air pipe 6 below the connecting ring 7 extends into the tank body 1, the connecting ring 7 is inserted into the connecting port 21 and is sealed and connected to the connecting port 21, and the second valve 16 is opened to keep the material taking pipe 8 unobstructed. By pressing the airbag 5, the air in the airbag 5 is pressed out and enters the tank body 1, and an air pressure difference is generated inside and outside the tank body 1, so that the lubricating oil is pressed into the material taking pipe 8 and flows out from the discharge head 9. The airbag 5 can be pressed multiple times for collection according to the required sampling amount. When a large amount of lubricating oil is taken, the second valve 16 is closed, and the connecting ring 7 is pulled out upwards, so that the sealing plug 4 is re-inserted into the connecting port 21, and the first valve 15 is opened to take the lubricating oil out from the oil outlet 111.
