Description of drawings:

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model.

Detailed ways:

As shown in Figure 1, a long-distance pipeline nozzle plugging device includes a baffle 1 capable of blocking the nozzle; Connect the connecting lever 10, the front end of the connecting lever 10 is provided with a push plate 3, the threaded push rod 7 is threaded on the push plate 3, the tail end of the threaded push rod 7 is connected with the connecting lever 10 in rotation, and the threaded push rod 7 rotates along the threaded hole on the push plate 3 The connecting puller 10 can be pushed to move, and the two ends of the push plate 3 are provided with pull plates 4, and the two pull plates 4 are located on both sides of the blocked pipeline and are fixed on the blocked pipeline by a fixing mechanism.

The sealing layer on the baffle plate 1 adopts the elastic rubber layer 2, and the sealing effect is good.

An anti-skid plate 12 is arranged around the side of the baffle plate 1 in contact with the mouth of the pipe, and the anti-skid plate 12 is bell-shaped to prevent the baffle plate 1 from slipping off from the pipeline.

The front end of the threaded push rod 7 is provided with a swivel 8, which is convenient for rotating the threaded push rod 7.

The fixing mechanism includes a screw 5 and a pressure plate 6, the screw 5 is threadedly connected with the pull plate 4, the bottom of the screw 5 is connected with the pressure plate 6 in rotation, the bottom surface of the pressure plate 6 is provided with a non-slip rubber layer 13, the bottom surface of the pressure plate 6 matches the side wall surface of the blocked pipeline, Rotating the screw 5 can fix the pressing plate 6 on the side wall of the blocked pipeline. The anti-slip rubber layer 13 increases the frictional force and prevents the pipeline from being squeezed.
