BACKGROUND OF THE PRESENT INVENTION
Field of Invention
A funnel assembly is placed in an oil fill hole and used for pouring motor oil into cars or motorcycles. Thus the motor oil is poured into containers with the oil fill hole smoothly, without being spilled.
Description of Related Arts
A funnel is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, the liquid may be spilled.
However, the positions of the oil fill holes on oil containers of various cars or motorcycles are different. The oil fill hole may be arranged at an upper or a lower place of the engine case. For users, it may be difficult to insert a stem of the funnel into the oil fill hole. The stem of the funnel is generally linear and there are various types of funnel, such as those revealed in Pat. No. ES1119986 and Pat. App. Pub. No. US2012152408.These funnels can be applied to oil fill holes at different positions. A flexible hose is connected to the funnel and a ball valve is arranged at the stem of the funnel so that the funnel can be rotated to different directions.
The shortcoming of the funnel revealed in Pat. App. Pub. No. US2012152408 is in that a flexible and bendable hose is used as the stem of the funnel However, the flexible hose is difficult to be fixed and positioned. The flexibility also causes trouble in use. The hose is easy to twist and is unable to be fixed. Once users don't hold the hose properly, the hose is easy to be released from the oil fill hole and the motor oil is spilled.
As to Pat. ES1119986, the ball valve on the stem is connected to a cap. After the cap being covered on the oil fill hole, the vector of phase of the funnel can be adjusted. The disadvantage of the device is in that the funnel is unable to be fixed at the position after adjustment. This is due to that there is no positioning member between the ball valve and the cap. Thus users need to hold the funnel with one hand while the other hand is used for pouring the motor oil. The funnel revealed in the Pat. US2012152408 also got the same problem.
SUMMARY OF THE PRESENT INVENTION
Therefore it is a primary object of the present invention to provide a funnel assembly able to be inserted into oil fill holes of various cars and allowing users to change assembly angle of the funnel assembly easily. Moreover, the funnel assembly is positioned right after the adjustment of the assembly angle. Thus the user can pour the motor oil conveniently, without spilling the motor oil out of the funnel assembly or the oil fill hole.
In order to achieve the above object, a funnel assembly used for adding motor oil into cars or motorcycles of the present invention includes a main body, a first sleeve, an extension tube, a second sleeve and a cover. All the components are detachable.
The main body (funnel) includes a receiving portion while the receiving portion having a first open end and a second open end.
The first sleeve consists of a first axial part and a second axial part.
The second sleeve is composed of a third axial part and a fourth axial part.
The extension tube includes a first opening and a second opening.
The cover includes a base and a threaded part. The base is arranged with a mounting hole.
The second open end of the main body (funnel) is connected to the first axial part of the first sleeve and the second axial part of the first sleeve is assembled with the first opening of the extension tube. The second opening of the extension tube is connected to the third axial part of the second sleeve while the fourth axial part of the second sleeve is assembled with the mounting hole of the cover.
The extension tube can be connected to and positioned with the first sleeve and the second sleeve at different angles for being adjusted to the direction required. The second sleeve and the cover can be connected to and positioned with each other at different angles.

By the above three-stage adjustment, the funnel assembly can be assembled at different angles and adjusted to various directions.
The funnel assembly of the present invention has following advantages.
1. As shown in FIG. 4, a schematic drawing showing the assembled funnel assembly. Refer to FIG. 5, when the first sleeve 2 and the extension tube 1 are aligned with each other at different angle so that the first axial part 21 is toward another direction. The first sleeve 2 includes the first axial part 21 and the second axial part 22 while the second sleeve 3 includes the third axial part 31 and the fourth axial part 32. By changing angles of the second axial part 22, the third axial part 31, the first axial part 21 and the fourth axial part 32 being assembled with the extension tube 1, a tube formed by the sleeves 2, 3 and the extension tube 1 is bent toward different directions.
2. By the stopping slots 221 on the second opening end 22a of the first sleeve 2 and the positioning slots 311 on the first opening ends 31a of the second sleeve 3, the long ribs 11a of the extension tube 1 are connected to and positioned with each other at different radial angles, without shaking or rotation.
