Description

Technical Field

[0001] The utility model relates to the technical field of aircraft maintenance, in particular to an oil tank hole opener. Background Art

[0002] During line maintenance, the aircraft needs to be refilled with lubricating oil every day. Since the engine oil filling port is inside a small cover plate, it is impossible to add lubricating oil with other tools. The only way is to use tools to drill a hole in the oil tank, and then hold the oil tank by hand and put it into the cover plate to add oil.

[0003] The existing hole-opening method is to use a flat-blade screwdriver or a can opener with a catheter. When using a flat-blade screwdriver, the left hand needs to hold the lubricating oil tank and the right hand needs to hold the flat-blade screwdriver to smash it down. Improper force application may easily hurt people; the hole opening position is not fixed and the position may be too far from the side wall, so multiple holes need to be opened; the hole diameter needs to be enlarged after opening, which is troublesome to operate; the lubricating oil can opener with a catheter is easy to be contaminated due to the large amount of residual lubricating oil, and needs to be cleaned after each use, which is inconvenient.

The lower ends of the first cone head 202 and the second cone head 302 do not protrude from the accommodating groove 101. When the staff presses the first rod body 201 and the second rod body 301, the first cone head 202 and the second cone head 302 extend from the accommodating groove 101, thereby preventing the cone heads from being exposed and easily cutting the staff when the oil tank hole opener is not in use, thereby preventing safety problems.

[0034] More preferably, the main body 1 also includes a cover body 102, the cover body 102 includes a cover plate 1021 and a cover edge 1022 arranged on the outer periphery of the cover plate 1021 and extending downward, the cover plate 1021 is fixedly arranged at the lower end of the accommodating groove 101, and a first through hole 10211 and a second through hole 10212 are opened on the cover plate 1021, the first through hole 10211 and the second through hole 10212 are respectively located at the two ends of the cover plate 1021 along the first direction, the first cone head 202 is opposite to the first through hole 10211, and the second cone head 302 is opposite to the second through hole 10212. A cover plate 1021 and a cover edge 1022 are arranged to be installed and positioned in coordination with the end face and the tank body of the oil tank, so as to facilitate the hole opening operation and increase the stability of the hole opening; a first through hole 10211 and a second through hole 10212 are opened, and the first through hole 10211 and the second through hole 10212 are respectively located at the two ends of the cover plate 1021 along the first direction, so that the vent hole and the pouring hole opened on the end face of the oil tank are respectively located at the two ends of the same straight line direction, and are both close to the tank body, and when the oil is poured out, the oil only flows out from the pouring hole and is difficult to flow out from the vent hole, and after the oil is poured out, there is almost no residual oil in the oil tank.

[0035] More preferably, it further comprises a handle 6, which is detachably mounted on the first rod body 201 and the second rod body 301. The handle 6 is arranged to connect the first rod body 201 and the second rod body 301, and the pouring hole and the vent hole can be simultaneously opened on the oil tank by pressing the handle 6 once.

[0036] More preferably, the invention further comprises a first nut 7, a second nut 8, a third nut 9 and a fourth nut 10, the first rod 201 has a first threaded portion 203 at one end away from the first cone head 202, the second rod 301 has a second threaded portion 303 at one end away from the second cone head 302, the first nut 7, the handle 6 and the second nut 8 are sequentially sleeved on the first threaded portion 203 from top to bottom, the first nut 7 is fixedly connected to the upper end of the first spring 4, and the upper end of the first spring 4 is connected to the first threaded portion 203 through the first nut 7; the third nut 9, the handle 6 and the fourth nut 10 are sequentially sleeved on the second threaded portion 303 from top to bottom, the third nut 9 is fixedly connected to the upper end of the second spring 5, and the upper end of the second spring 5 is connected to the second threaded portion 303 through the third nut 9. The first nut 7 and the second nut 8 are meshed with the first threaded portion 203, and the third nut 9 and the fourth nut 10 are meshed with the second threaded portion 303. The elastic force of the spring can be adjusted by adjusting the first nut 7 and the third nut 9. When the first nut 7 and the third nut 9 are screwed downward, the first spring 4 and the second spring 5 are compressed and the elastic force increases, which can maintain the reset ability of the first cone rod 2 and the second cone rod 3 and offset the weakening of the elastic force of the first spring 4 and the second spring 5 after long-term use.

[0037] More preferably, both ends of the handle 6 have an extension portion 601 extending along the first direction. The extension portion 601 is provided to extend the handle 6, and the staff can assist in applying force by pressing the extension portion 601 of the handle 6, making the pressing operation more efficient.
