Embodiment 1

[0023] Such as figure 1 , figure 2 with image 3 As shown, this embodiment includes a hollow hemispherical sealing cover 1 and a push rod 2 fixed on the bottom of the sealing cover 1. On the outer eaves of the sealing cover 1, an annular enlarged part 4 with the middle part sunken inward is fixed. The enlarged part 4 is elastic rubber, and a plurality of arc-shaped pieces 3 are embedded on the outer wall of the sealing cover 1. The plurality of arc-shaped pieces 3 are radial along the direction from the bottom of the sealing cover 1 to its outer circumference. The end of the arc-shaped piece 3 is connected with an arc-shaped elastic metal block 5, and the elastic metal block 5 is embedded in the depression of the enlarged part 4; it also includes an arc-shaped block 7 and an arc-shaped connecting plate 14 connected thereto , a positioning block 11 is installed on the movable end of the connecting plate 14, and the middle part of the positioning block 11 is provided with a s...

Abstract

The present invention discloses a tubing packer capable of rapidly implementing blocking. The tubing packer comprises a hollow hemispheric sealing cover and a push rod fixed at the bottom of the sealing cover; an annular expansion portion with the middle inwardly recessed is fixed on an outer edge of the sealing cover; a plurality of arc-shaped pieces are embedded into an outer wall of the sealing cover; the plurality of arc-shaped pieces are radially disposed in directions from the bottom of the sealing cover towards the outer circumference of the sealing cover; and the tail end of each arc-shaped piece is connected with an arc-shaped elastic metal block embedded in the recessed position of the expansion portion. Through self displacement changes of the hollow hemispheric sealing cover, air in a pipeline can be compressed and extruded, so that air pressure of the outside of the sealing cover is slightly greater than that of the inside of the sealing cover, the sealing cover can be fixed on an inner wall of the pipeline more stably, and the problem that a traditional blocking device is poor in practicability and inconvenient to use is solved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an oil pipe packer for rapidly realizing plugging. Background technique [0002] The oil tank and the engine are connected by an oil pipeline, but when the engine has equipment failure or needs to be repaired, the oil pipeline needs to be disconnected, that is, the opening and closing of the oil delivery is realized through the switch valve, but due to the existence of A certain distance, and there is still a certain amount of oil in the oil pipeline after the on-off valve is closed. After the oil leaks, it will easily cause pollution to the surrounding environment and cause a large waste; Plugging is carried out to prevent the staff from opening the pipeline without knowing it, causing leakage and affecting the maintenance progress. In the past, matching oil pipe end caps were generally used for sealing when plugging, but due to the poor sealing performance of the end cap...
