Description

Technical Field

[0001] This utility model relates to the field of oil filter housing technology, and in particular to a dual-filter quick-connect oil filter housing structure. Background Technology

[0002] The oil filter in a model aircraft is a key component used to filter fuel, which is essential for ensuring the normal operation of the model aircraft engine.

[0003] Currently, some model aircraft oil filters are made of all-plastic one-piece molding, with the plastic filter element injected into it. The disadvantage of one-piece molding is that it is not possible to quickly insert and remove the oil pipes, the installation is time-consuming and labor-intensive, and the production requires injection molds, so it is only suitable for mass production. Others use metal oil filters with threaded connections to the connectors on both sides. Metal oil filters are more expensive, and it is not possible to observe whether the filter element is clogged. Filters that allow observation of the filter element are more expensive, and it is not easy to quickly insert and remove the oil pipes. Utility Model Content

[0004] The purpose of this invention is to provide a dual-filter quick-connect oil filter housing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-filter quick-connect oil filter housing structure includes a transparent tube and two quick-connect connectors. The transparent tube has a through hole in the middle, and the two ends of the through hole are connected to the outer wall of the transparent tube with an arc surface and a flat surface. The quick-connect connector includes an end cap, a first conical tube, and a second conical tube connected in sequence. The end cap has an oil pipe interface, and the second conical tube has an annular boss with an inlet and outlet connected to the annular boss. The oil pipe interface passes through the end cap, the first conical tube, the second conical tube, and the annular boss in sequence and is connected to the inlet and outlet. The connection between the first conical tube and the second conical tube forms a connecting ring surface. The two quick-connect connectors are inserted into the through hole through the second conical tube and are positioned on both sides of the transparent tube, with the connecting ring surface fitting against the flat surface of the tube.

[0007] Preferably, the end cap is movably mounted on the tapered tube, and a retaining spring is provided inside the end cap for fixing the oil pipe.

[0008] Preferably, the transparent tube is a plastic transparent tube, the quick-connect fitting is made of plastic, and the quick-connect fitting is assembled with the transparent tube by a tight-fitting heat fitting method.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This utility model achieves a split design by cutting a PU or PG type quick plug in the middle. The cut quick plug is finely processed to ensure a tight fit with the middle transparent tube, preventing oil leakage and ensuring an aesthetically pleasing appearance. The plastic quick-connect fittings at both ends allow for easy insertion and removal of the oil pipe, and are compact and lightweight. The middle transparent tube is made of transparent plastic, allowing observation of the filter element's oil condition.

[0011] This invention is low in cost, can be customized in small quantities, and does not require mass production; the product is beautiful and lightweight, easy to use, and can achieve instant insertion and removal of oil pipes; the pipe body is transparent, allowing for observation of oil stains at any time.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] like Figure 1-4 As shown, a dual-filter quick-connect oil filter housing structure includes a transparent tube 1 and two quick-connect connectors 2. The transparent tube 1 has a through hole 11 in the middle, and the two ends of the through hole 11 are provided with tube arc surface 12 and tube plane 13 connected to the outer wall of the transparent tube 1.

[0020] The quick-connector 2 includes an end cap 21, a first tapered tube 23, and a second tapered tube 24 connected in sequence. The end cap 21 is provided with an oil pipe interface 22, and the second tapered tube 24 is provided with an annular boss 26. An oil inlet and outlet port 27 are connected to the annular boss 26. The oil pipe interface 22 passes through the end cap 21, the first tapered tube 23, the second tapered tube 24, and the annular boss 26 in sequence and is connected to the oil inlet and outlet port 27. The end cap 21 is movably mounted on the first tapered tube 23. A retaining spring is provided inside the end cap 21 to fix the oil pipe. The internal structure and principle of the quick-connector 2 are existing technologies and will not be described in detail here.

[0021] The connection between tapered tube 1 23 and tapered tube 24 forms a connecting ring surface 25. Two quick-connect fittings 2 are inserted into the through hole 11 through tapered tube 24, so that they are located on both sides of the transparent tube body 1, and the connecting ring surface 25 is in contact with the tube body plane 13. The transparent tube body 1 is a plastic transparent tube, and the quick-connect fittings 2 are made of plastic. The quick-connect fittings 2 are assembled with the transparent tube body 1 by a tight-fitting heat fitting method. The filter screen is set between the oil inlet and outlet ports 27 of the quick-connect fittings 2 on both sides of the through hole 11 of the transparent tube body 1 to filter fuel.

[0022] This invention achieves a split design by cutting a PU or PG type quick-connect plug in the middle. The cut quick-connect plug is finely processed to ensure a tight, heat-fitted fit with the central transparent tube 1, preventing oil leakage and ensuring an aesthetically pleasing appearance. The plastic quick-connect fittings 2 at both ends facilitate easy insertion and removal of the oil tubing, and are compact and lightweight. The central transparent tube 1 is made of transparent plastic, allowing observation of the filter element's oil condition. This invention is low-cost, can be customized in small quantities, and does not require mass production. The product is aesthetically pleasing, lightweight, and easy to use, allowing for quick insertion and removal of the oil tubing. The transparent tube allows for easy observation of the oil condition at any time.
