Description

Technical Field

[0001] This utility model relates to the field of aviation lubricating oil filling technology, and more specifically, to an integrated device for opening and filling aviation lubricating oil cans. Background Technology

[0002] Aircraft engines require regular lubrication with lubricating oil to lubricate components and dissipate heat. However, due to the complex mechanical structure of aircraft engines, the lubricating oil filling port is relatively small. Furthermore, the metal cans used to store aviation lubricating oil do not have quick-release rings to ensure a tight seal. Before each use, two holes (one for venting) must be punctured on the top of the can using a can opener or flathead screwdriver. Due to the lack of specialized tools, the size and shape of the openings cannot be guaranteed to be standardized. During the lubricating oil filling process, oil may overflow from the filling port due to excessively large or irregularly shaped holes, resulting in resource waste and safety hazards. In addition, if the opening is too small, the oil flow may be unstable, reducing work efficiency. Furthermore, there is a risk of personal injury due to the worker's technique or physical condition while puncturing the opening. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated device for opening and filling aviation lubricating oil cans, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0005] An integrated device for opening and filling aviation lubricating oil cans includes:

[0006] Protective sleeve 100, wherein the protective sleeve 100 is constructed as a cylindrical component with an open bottom;

[0007] Can opener 200, which is vertically installed on the top surface inside the protective sleeve 100, has two blades 210 with pointed ends;

[0008] A limiting member 300 is installed on the inner top surface of the protective sleeve 100, and the lowest point of the limiting member 300 is higher than the lowest point of the cutter head 210.

[0009] A filling hose 400, one end of which is connected to the outer top surface of the protective sleeve 100 and communicates with the interior of the protective sleeve 100.

[0010] Furthermore, a handle 110 is provided on the outer top surface of the protective sleeve 100, and the filling hose 400 is inserted inside the handle 110.

[0011] Furthermore, the inner top surface of the protective sleeve 100 is configured as an upwardly tapered surface.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] See Figures 1 to 4 This embodiment provides an integrated device for opening and filling aviation lubricating oil cans, including: a protective sleeve 100, a can-opening blade 200, a limiting component 300, and a filling hose 400.

[0031] The protective sleeve 100 is a cylindrical component with an open bottom. The protective sleeve 100 is used to cover the outside of the tank. In this embodiment, the size of the open bottom of the protective sleeve 100 is adapted to the external dimensions of the tank. A vent hole 120 is provided on the bottom side wall of the protective sleeve 100. When the protective sleeve 100 is covered on the tank, it can balance the pressure difference inside and outside the protective sleeve 100 and improve the liquid injection speed.

[0032] The inner top surface of the protective sleeve 100 is configured as an upwardly tapered surface 130. When the protective sleeve 100 is flipped or tilted, the tapered surface 130 can ensure that the surrounding oil can gather at the center top and flow out from the top, thus preventing residual liquid from remaining inside the protective sleeve 100.

[0033] A handle 110 is provided on the outer top surface of the protective sleeve 100. The handle 110 has a hollow structure with a hollow cavity 111. The hollow cavity 111 is connected to the top of the inner top surface of the protective sleeve 100. The handle 110 facilitates the handling of the protective sleeve 100 during operation.

[0034] The can opener 200 is vertically installed on the top surface inside the protective sleeve 100. The can opener 200 has two blades 210 with pointed ends. Each blade 210 has a single-sided blade 211 with a triangular cutting edge. When pressed down, it can open a triangular hole in the top surface of the can.

[0035] In this embodiment, the blade 211 is also provided with a protruding part 212 that protrudes outward. The outer side of the protruding part 212 extends obliquely from bottom to top towards the outer side of the blade 211. The thickness of the protruding part 212 is greater than the thickness of the blade 211, which can increase the size of the opening to the tank and increase the air permeability and lubricating oil flow rate.

[0036] In this embodiment, the cutter head 210 is also provided with a vertical flow groove. When the cutter head 210 is inserted into the top skin of the tank, it can provide a channel for the lubricating oil in the tank to flow out, thereby accelerating the flow rate of the lubricating oil.

[0037] The limiting member 300 is installed on the inner top surface of the protective sleeve 100. The lowest point of the limiting member 300 is higher than the lowest point of the cutter head 210. When the cutter head 210 is pressed down, the cutter head 210 penetrates the tank skin. When the bottom of the limiting member 300 contacts the tank skin, the cutter head 210 cannot continue to move downward. The limiting member 300 can limit the penetration stroke of the cutter head 210 and ensure that the size and shape of the opening of the cutter head 210 to the tank skin are uniform.

[0038] In this embodiment, the limiting member 300 is disposed between the two cutting heads 210. The bottom of the limiting member 300 is set as a plane, which is in surface contact with the top skin of the tank to ensure the limiting effect.

[0039] One end of the filling hose 400 is connected to the outer top surface of the protective sleeve 100 and communicates with the interior of the protective sleeve 100. In this embodiment, the filling hose 400 is inserted into the hollow cavity 111 inside the handle 110. The handle 110 can prevent the root of the connection between the filling hose 400 and the protective sleeve 100 from bending or breaking. The filling hose 400 communicates with the top end of the conical surface 130 inside the protective sleeve 100. At the same time, the filling hose 400 and the hollow cavity 111 are sealed to prevent leakage during the injection process.

[0040] The working principle of the integrated aviation lubricating oil can opening and filling device provided in this embodiment:

[0041] In use, the protective sleeve 100 is placed on the outside of the tank body and pressed down forcefully. The two blades 210 penetrate the top skin of the tank body. Continue pressing until the bottom of the limiting member 300 contacts the top skin of the tank body, and the opening is completed. At this time, two marked holes are formed on the top skin of the tank body. One hole is used for adding oil, and the other hole is used for venting. Then, the filling hose 400 is inserted into the aircraft engine lubricating oil filling port. The tank body and the protective sleeve 100 are then flipped or tilted together, and the oil in the tank body enters the aircraft engine lubricating oil filling port through the filling hose 400.
