Embodiment 1

[0036] Such as figure 1 , figure 2 with image 3 As shown, it includes a connecting pipe body 1, an internal thread 2 arranged on the inner wall of the connecting pipe body 1 and matched with the external thread of the oil pipeline interface, and both ends of the connecting pipe body 1 are provided with fastening devices 3 .

[0037] The fastening device 3 includes a ring fastener 31, a ring buckle 32 that is sleeved on the ring fastener 31 and threaded with the ring fastener 31; the two fastening devices 3 are symmetrically arranged, and the two A telescopic rod 4 is arranged between the buckles 32 on the fastening device 3 .

[0038] One end of the telescopic rod 4 is hinged on one of the buckles 32 , the other end is a free end, and the other buckle 32 is provided with a fixing device for fixing the free end of the telescopic rod 4 .

[0039] The fixing device includes a locking groove 5 arranged on the ring buckle 32 and a spring stopper 6 arranged in the locking groo...

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the structure of the gasket 34 is added in this embodiment, and the specific structure of the fastening rod is optimized, which is set as follows:

[0046] The fastening rod is a strip structure, and the cross section of the fastening rod is an arc trapezoidal structure. The fastening rod is provided with a washer 34 whose thickness gradually decreases along the direction of the fixed end. Through the above settings, a more stable connection can be effectively achieved.

Abstract

The invention discloses an oil pipeline connection part with a telescopic rod, which solves the problem that the existing oil pipelines connected at both ends cannot be effectively and freely rotated, and the installation of couplings cannot be well realized. The invention comprises a connecting pipe body, an internal thread arranged on the inner wall of the connecting pipe and matched with an external thread at the interface of the oil pipeline, fastening devices are arranged at both ends of the connecting pipe body; the fastening device It includes a ring fastener, a ring buckle that is sleeved on the ring fastener and threaded with the ring fastener; the two fastening devices are arranged symmetrically, and the ring buckles on the two fastening devices are provided with Telescopic rod; one end of the telescopic rod is hinged on one of the buckles, the other end is a free end, and the other buckle is provided with a fixing device for fixing the free end of the telescopic rod. The invention has the advantages of simpler installation, more stable connection between the collar and the oil pipeline, and the like.

Description

technical field [0001] The invention relates to a connecting pipe, in particular to an oil pipeline connecting part with a telescoping rod. Background technique [0002] Pipeline transportation is the most economical and reasonable transportation method for crude oil transportation. The pipeline transports crude oil, and the connection between the oil pipes is usually connected by the oil pipe coupling. The oil pipe coupling has a tubular coupling body, and the two ends of the coupling body have connecting internal threads. The threaded oil pipe is screwed into the internal thread of the oil pipe coupling to form a continuous oil transportation pipeline and realize continuous oil transportation. The connection seal between the oil pipe collar and the oil pipe in the above-mentioned prior art is generally to wrap glass filament or hemp rope on the outer thread of the oil pipe first, and then screw the oil pipe wrapped with glass silk or hemp rope into the oil pipe collar. T...
