Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

Referring to fig. 1-2, the present embodiment includes a screw 1 having a first guiding hole 11 and a nut 2 having a second guiding hole 21, the screw 1 is fixedly connected to the nut 2, and the first guiding hole 11 is communicated with the second guiding hole 21; the fast-assembling pipeline sampling device also comprises a switch member 3 which is arranged in the nut 2 and is in threaded connection with the nut 2 and used for separating or communicating the first guide hole 11 and the second guide hole 21.

The screw rod sealing device further comprises a sealing gasket 4 sleeved on the screw rod 1, wherein in the embodiment, the sealing gasket 4 is a fluorine rubber sealing gasket. The provision of the seal 4 prevents leakage of the liquid in the pipe.

One end of the screw 1 close to the screw cap 2 is a plastic screw 12, and the other end is a metal screw 13. The plastic screw 12 is provided with external threads, the metal screw 13 is provided with internal threads, the plastic screw 12 is in threaded connection with the metal screw 13, and the plastic screw 12 is favorable for reducing cost.
