Description

TECHNICAL FIELD

[0001] The utility model is applied to the field of oil guide pipe installation, and particularly relates to a quick connection oil guide pipe structure. BACKGROUND

[0002] People often use oil guide pipes in cooperation with oil drums, and after connecting the oil guide pipe, oil in the oil drum can flow to a designated container or equipment under the action of gravity or pressure. For example, when refueling a car, the gasoline in the oil drum is delivered to the oil tank of the car through the connected oil guide pipe. At the same time, compared with directly pouring the oil drum, the connected oil guide pipe can better control the speed and amount of oil outflow.

[0003] At present, when connecting the oil guide pipe and the oil drum, a direct insertion type is often used, that is, the oil guide pipe is directly inserted into the oil drum opening. However, in this way, the connection is not sealed, the connection is not firm, the oil guide pipe is easy to accidentally fall off or the oil spills out during oil pouring, causing oil leakage. In order to stabilize the oil guide pipe, a person is needed to hold it, which not only occupies energy, but also is unhygienic. If a flange connection method is used, flanges are respectively installed on the oil drum and the oil guide pipe, and they are fastened together by bolts. However, the structure is complex to operate, more components are needed, and the installation and disassembly are relatively troublesome. SUMMARY

[0007] The quick connection structure comprises a bottom gland and a top gland, the bottom gland and the top gland are integrally connected, and the centers of the bottom gland and the top gland are on the same vertical line.

[0008] The outer ring surface of the bottom gland has a gland outer thread structure, the inner ring surface of the bottom gland has a gland inner thread structure, the gland outer thread structure is threadedly combined with the outer ring thread structure of the fixed threaded column, and the gland inner thread structure of the bottom gland is threadedly combined with the thread structure on the cover body.

[0009] The top plug is connected with an outer ring threaded convex, which is screwed together with the inner ring inner threaded structure of the fixed threaded column through threaded structure.

[0010] The oil bucket is connected with the quick connection structure through the fixed threaded column.

[0011] The top plug of the quick connection structure can be inserted into the oil port of the oil bucket.

[0012] The inner ring surface of the top plug is connected with a baffle.

[0013] The inner ring surface of the top plug is provided with an annular groove, and the annular groove is clamped with an elastic sheet.

[0014] The filter screen 10 is installed between the baffle and the elastic sheet.

[0015] The oil bucket is connected with the quick connection structure through the fixed threaded column.

[0016] The beneficial effects achieved by the utility model are as follows:

[0017] The oil bucket and the oil guide pipe can be detachably connected through the quick connection structure, the oil guide pipe can be directly inserted into the oil bucket through the quick connection structure, the oil buckets can be tightly stacked, the transportation and storage space is saved, the connection part can be prevented from being damaged due to collision during transportation, and the oil waste and safety risk caused by leakage can be avoided.

[0018] The utility model has high connection tightness: the connection between the oil guide pipe and the fixed threaded column above the oil bucket is relatively tight through the rotation and engagement of the threads, the splashing phenomenon does not occur during the oil discharge process, the oil leakage can be effectively prevented, and the artificial support is not needed.

[0019] The utility model is simple to install, compared with some complex connection modes, such as flange connection and threaded connection, too many additional tools and components are not needed.

[0020] When the oil body in the oil drum is poured out, the quick connecting structure is taken off from the fixed threaded column at the top of the oil drum, then is turned over by 180 degrees, the gland inner thread structure on the bottom gland of the quick connecting structure is screwed with the outer circle inner thread structure of the fixed threaded column, after screwing, the quick connecting structure is fixed with the fixed thread between the top of the barrel body, at this time, the oil guide pipe is arranged at the top of the oil drum, holds the handle, the oil body in the oil drum is transported to outside of the oil drum through the oil guide pipe.
