It is characterized by easy removal by rotating the oil filter case even with a wrench. .

Description

A structure of oil filter case for easy fastening and loosening}

The present invention relates to a vehicle and a general oil filter case detachable device.

More specifically, a square key groove and an external polygon-shaped wrench coupling end are integrated into the oil filter case for automobiles and general oil filter cases so that they can be easily attached and detached with a square protrusion wrench commonly used as a general tool. It is about.

In the vehicle, oil is introduced into the engine so that the engine can operate smoothly, and the engine performs lubrication, cooling, cleaning, rust prevention, and stress dispersion. Impurities, such as carbide, powder, and moisture, are included in the oil, and these impurities must be removed from the oil filter. The oil filter becomes impurity after a certain period of time and must be replaced with new ones.

However, the interior of the car has become more complicated due to the development of its function, so that there is not enough space for replacing the oil filter. Therefore, it is not easy to replace the oil wheel. The polygon is formed so that the oil filter case can be detached by rotating this part, but the unevenness of the angled part is not clear, and the oil filter case is rotated by applying a force to the engine body using various wrenches. Since the slipping occurs frequently when detaching, the oil filter case is not easy to attach or detach and the oil leaks due to incomplete coupling, which causes difficulties in auto repair shops and general maintenance companies (car centers, industrial companies, etc.). It is true.

Publication No. 1998-061945 Publication Date 1998.11.16 Although various tools such as a semi-automatic oil filter wrench (Fig. 3d) have been developed, these detachable tools do not meet the expected effects, and most of the development tools are prepared exclusively for oil filter case replacement, and thus prepare these tools separately. And depending on the vehicle, Because the size of different device could also be challenged to prepare a large variety of tools.

The present invention aims to solve this problem. The oil rotor case can be conveniently rotated using a square projection wrench or a polygon keyway wrench that is generally used for any parts of the oil rotor case without using a separate tool for attaching or removing the oil rotor case. The purpose is to provide a new oil filter case.

In order to achieve this purpose, by integrating a wrench coupling end formed with a square inner groove (key home) and an outer polygonal projection at the center of the lower portion of a conventional oil filter case, the oil filter case can be easily rotated and detached with a general wrench. It is characterized by.

3: internal coupling hole 3 ': square protrusion

4: outer polygon protrusion 4 ': polygonal keyway

5: Square projection wrench 5 ': Polygon keyway wrench

Referring to the present invention in detail by the drawings as follows.

A wrench coupling end 2 is formed at the center of the lower portion of the conventional oil filter case 1, and an inner coupling hole 3, which is a square keyway corresponding to the square projection 3 'of the square projection wrench 5, is formed therein. Forming and turning the square projection (3 ') of the square projection wrench (5) into the inner coupling hole (3) to generate a strong torque (tork torque) can be rotated, the oil rotor case (1) A polygonal key groove formed with a hexagonal or polygonal outer polygonal projection 4 formed with a polygonal key groove 4 'corresponding to the outer polygonal projection 4 when the square projection wrench 5 is not used. By applying and rotating the wrench 5 '(spanner), the oil filter case 1 can be easily rotated and detached.

On the other hand, the inner coupling hole (3) formed inside the wrench coupling end (2) may be formed in a polygon, but a quadrangle that can exert the greatest torque force is suitable, and all can be commonly used in accordance with international standards. In addition, the outer polygon protrusion 4 formed outside the wrench coupling end 2 may be a polygon or more polygonal polygon polygon key groove (4 ') formed in accordance with this polygon key groove wrench (5') can be used in combination.

To replace the oil filter case, there is no need to provide a separate wrench, and use the general wrench that is commonly used by integrating the wrench coupling end of the oil filter case itself with a square keyway corresponding to the wrench inside and polygonal outer part. The oil filter case can be easily removed.

Claims (1)

In automobile and general oil filter, a wrench coupling end 2 is formed at the lower center of the oil filter case 1, and the inside of the wrench coupling end 2 is a square projection 3 'of the square projection wrench 5; The inner coupling hole (3) is formed in the corresponding square keyway and the outer side of the wrench coupling end (2) is a structure of the removable oil filter case, characterized in that the polygonal outer polygon projection (4) is formed.
