Background

Along with the rapid development of economy in China, the living standard of people is continuously improved, the quantity of automobiles in China is continuously increased, the number of built gas stations is increased, in the process of building the gas stations, the connecting part of the oil pipes of the oiling machines needs to be sealed and subjected to anti-drop treatment, if the pipelines are not sealed tightly, leakage occurs, if the pipelines are not sealed tightly, the oiling metering is inaccurate, the environment is polluted, and if the pipelines are not sealed tightly, fire explosion is caused; therefore, the sealing and the anti-dropping of the pipeline of the oiling machine also become important technical problems to be solved in the process of building a gas station.

The connecting mechanism of the internal pipeline of the existing oiling machine and the joint comprises a joint, a sealing ring, a compression ring and a locking nut, when the connecting mechanism is connected, parts are sequentially assembled, connecting threads of the locking nut and the joint are screwed, and the internal compression ring compresses the sealing ring along the axial direction of an oil pipe to keep an oil way sealed (see fig. 1 and 2); the compression ring not only compresses the sealing ring, but also prevents the locking nut from twisting and deforming to the sealing ring, plays a certain sealing role along the circumference of the oil pipe, but does not play a great role in axial movement; the existing solution is that a snap ring is usually additionally arranged between a seal ring and a lock nut, the snap ring is provided with a pressing end and a clamping end, the pressing end presses against a compression ring, and the clamping end is arranged along the outer wall of an oil pipe; however, when the nut is screwed, the operation is usually performed according to the working experience of constructors, certain construction errors exist, the sealing is not tight due to too light screwing, the dropping situation is easy to occur, the oil filling pipe is deformed due to excessive screwing, and even the pipeline is damaged, so that the pipeline is broken.

Therefore, under the background of emphasizing the safety, environmental protection, greenness and high efficiency of the gas station, the research and development of the structure capable of solving the problems of poor sealing and pipeline falling of the existing oiling machine pipeline connection is particularly urgent.

Disclosure of Invention

The utility model aims to provide a pipeline sealing mechanism of an oiling machine, and aims to solve the technical problems that the existing pipeline connecting mechanism of an oil pipe cannot prevent an oil circuit from generating water hammer effect or impact force during vibration, and the pipeline sealing structure fails and is separated after a long time, so that oil leakage is generated.

In order to solve the technical problems, the utility model adopts the following technical scheme:

designing an oiling machine pipeline sealing mechanism, which comprises a joint, a sealing ring, a compression ring, a locking nut and an oil pipe, wherein a connecting part connected with the oil pipe is arranged at the joint; the oil pipe adopts a rib pressing pipe, when the locking nut is sealed, one end of a rib pressing part of the rib pressing pipe abuts against the compression ring, and the other end of the rib pressing part abuts against the locking nut.

Preferably, the bead pressing pipe is an aluminum pipe.

Preferably, the bead is axially arranged along the bead tube.

Preferably, the beading position can not make the insertion end of the beading pipe exceed the joint.

Preferably, the top end of the joint connecting part is obliquely arranged and forms an included angle with the rib pressing pipe, and the sealing ring is arranged in the included angle.

Compared with the prior art, the utility model has the main beneficial technical effects that:

1. the utility model improves the original pipeline sealing structure, carries out ribbing treatment on the oil pipe, solves the problem of oil leakage caused by the separation of an axial oil way and also protects the integrity of the oil pipe structure.

2. The utility model solves the problem of pipeline sealing, does not change the whole structure too much, and can be continuously matched with original accessories, thereby greatly saving the production cost, having no need of specially training workers, and solving the problems of poor oil circuit sealing, pipeline falling and oil leakage caused by the experience problem of the constructors.
