DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown, the embodiment of the present utility model provides an anti-coagulation oil fume sampling tube, comprising:

[0023] The sampling tube body 1 is fixedly provided with a handle 15 on the outer side of the sampling tube 1, and the handle 15 is convenient for holding. A non-slip sleeve 16 is fixedly sleeved on the handle 15, and the non-slip sleeve 16 can play a role of anti-skid and heat insulation. A sealing cover 2 is sleeved on the front side of the sampling tube body 1 and is threadedly connected with the sealing cover 2. A heating pipe 8 and a collecting cylinder 3 are arranged in the sampling tube body 1. A heat insulation layer 14 is arranged on the inner wall of the sampling tube body 1. The heating pipe 8 is fixedly arranged on the heat insulation layer 14. The heat insulation layer 14 is made of heat insulation material and is used for blocking the heat of the heating pipe 8 and reducing heat loss.

[0024] A push-pull assembly is arranged between the collecting cylinder 3 and the sampling tube body 1. The push-pull assembly comprises a nut 9, a long rod 10, a screw rod 11 and a push-pull block 12. The nut 9 is fixedly arranged at the bottom of the collecting cylinder 3. The long rod 10 is slidingly arranged through the bottom of the sampling tube body 1. One end of the screw rod 11 is fixedly arranged at the inner end of the long rod 10. The screw rod 11 is threadedly connected with the nut 9. The push-pull block 12 is fixedly arranged at the outer end of the long rod 10. A heat insulation pad 13 is fixedly sleeved on the outer side of the push-pull block 12. The heat insulation pad 13 plays a role of heat insulation and avoids scalding of workers due to high-temperature transmission.

[0025] A piston 4 is arranged in the collecting cylinder 3 in a matched mode.
