Description

Oil core removal tool

The present invention relates to the field of vehicle maintenance, and in particular to a tool for performing a disassembly operation on the oil core of a car or motorcycle.

In order to lubricate and regulate the operating temperature, the car or motorcycle usually adds oil to an oil core. The oil core is removed by a removal tool. After the oil is changed, the oil core is installed in its original position.

Known disassembly tools, such as Taiwan Patent No. 294200, disclose that an actuation groove is formed at the bottom of a sleeve, and the actuation groove fits the appearance and functional shape of an oil core, so that the oil core rotates together with the sleeve. A protrusion is formed at the top of the sleeve, and an actuation hole is penetrated in the center of the protrusion, and the actuation hole receives a drive part. The drive part is part of a wrench, and transmits a torque of the wrench to the sleeve, which is applicable to the disassembly operation of the oil core.

Because the sleeve is formed in one piece, it is suitable for oil cores of a single size. If you want to remove oil cores of different specifications, you need to prepare sleeves of different sizes. The large number of sleeves not only takes up space, but is also inconvenient to carry around. Moreover, the production of the sleeve generates a cost, which is expensive and disadvantageous to market competition.

Therefore, how to improve the structure of the disassembly tool becomes an urgent problem to be solved by the present invention.

In view of this, the inventor of this case proposed a new disassembly tool, the main purpose of which is: adopting a modular structure, which can reduce the volume and be convenient to carry. The manufacturing cost is lower than the previous technology, which is highly competitive in the market. It can also assemble appropriate disassembly tools according to the size specifications of the oil core to perform disassembly operations.

In order to achieve the above purpose, the present invention includes: a cover, a first tube and a second tube. The cover has a wall, and the wall encloses a chamber. The first tube and the second tube are suitable for disassembling oil cores of different sizes and specifications. The first tube or the second tube is combined with the wall to form a disassembly tool with the cover.

In order to make the purpose, features and advantages of the present invention easy to understand, one or more preferred embodiments are given below with detailed descriptions in conjunction with the attached drawings.

For technicians in the field of this case, they can understand the specific meanings of the above terms in various embodiments and even this case based on their general knowledge or experience.

Unless otherwise specified, in the following descriptions, "plurality" means two or more.

In Figure 1, the first embodiment of a disassembly tool 10 of the present invention includes: a cap 11 and a set of cylinders.

In Figure 3, the cover 11 is inverted. The downward side of the cover 11 is defined as the top surface 12 and has a bulging force-bearing structure. The upward side of the cover 11 is considered as the bottom surface 13 and has a wall 20.

As shown in FIG. 4, in this embodiment, the force-bearing structure is a corner 14 with a hole 15. The corner 14 is a hexagonal design. In some embodiments, the corner 14 is a polygonal column. The hole 15 passes through the center of the corner 14, for example: a square hole. In some embodiments, the hole 15 is a polygonal groove, which is also within the allowable range of the present invention.

In FIG. 2, the wall 20 is annular in design, and has an inner side 21 and an outer side 22. The outer side 22 of the wall 20 is a circumferential surface, and three protrusions 26 are raised in equal parts. In some embodiments, the number of the protrusions 26 is one or more. The inner side 21 of the wall 20 is a multi-faceted structure formed by connecting multiple planes 25, which together form a chamber 23. One end of the chamber 23 is an opening facing the outside, and the other end leads to the end surface of the corner 14 through the hole 15 (see FIG. 7).

Looking back at Figure 1, it can be seen that the number of the set of cylinders is two, namely a first cylinder 18 and a second cylinder 19, which are suitable for disassembly or assembly of two oil cores 40 (see Figures 10 and 11) of different specifications. In some embodiments, the number of the set of cylinders is more than two.

In Figure 5, the first tube 18 is a toroidal body, the outer side of the toroidal body has a single diameter, and the inner side has two diameters 37 of different sizes, thereby extending a shoulder 34 in the circumferential direction. The shoulder 34 is used as a boundary to divide the first tube 18 into a thick-walled part and a thin-walled part (see Figures 1 and 7). Three grooves 35 are formed on the inner side of the thin-walled part, and each groove 35 is directly opposite to the corresponding protrusion 26.

As shown in FIG. 6 , the thin-walled portion is sheathed on the wall 20, or the wall 20 enters the thin-walled portion, and the cover 11 is combined with the first tube 18 to become the disassembly tool 10. At this moment, the groove 35 receives the protrusion 26, or the protrusion 26 slides into the groove 35, so that the cover 11 and the first tube 18 cannot move relative to each other. In other words, the cover 11 rotates with the first tube 18.

In FIG. 7 , the end of the first tube 18 contacts the bottom surface 13 of the cover 11, so that the first tube 18 is flush with the outer surface of the cover 11. The end of the wall 20 contacts the shoulder 34, preventing the wall 20 from continuing to penetrate into the first tube 18.

As shown in Figure 8, the cover 11 and the first tube 18 can be combined in other ways. The outer side 22 of the wall 20 forms a set of grooves 35' to receive a set of protrusions 26' of the thin-walled portion of the first tube 18, so that the cover 11 can rotate together with the first tube 18.

In Figure 9, the cover 11 and the first tube 18 are combined in another way. An L-shaped groove 35" forms the outer side 22 of the wall of the cover 11, receiving a protrusion 26" on the inner side of the thin-walled portion of the first tube 18, so that the cover 11 can rotate together with the first tube 18. In some embodiments, the protrusion 26" bulges the outer side 22 of the wall of the cover 11 and slides into the L-shaped groove 35" recessed in the thin-walled portion of the first tube 18, so that the cover 11 rotates together with the first tube 18.

As shown in Figure 10, when in use, the disassembly tool 10 covers an oil core 40. The corner portion 14 is inserted into one end of a sleeve 42, and the other end of the sleeve 42 is sleeved with a driving portion 43 of a wrench 41. The wrench 41 is subjected to force and rotates around the driving portion 43, transmitting a torque to the corner portion 14, allowing the disassembly tool 10 to remove the oil core 40.

Looking back at Figure 1, the second tube 19 is divided into two parts: a cylindrical part and a conical part. The inner side of the cylindrical part also has three grooves 35, which are respectively opposite to the protrusion 26.

As shown in FIG. 11, whether the cylindrical portion is sleeved on the wall 20 or the wall 20 enters the cylindrical portion, the cover 11 can be combined with the second cylinder 19 to become the disassembly tool 10. The groove 35 receives the protrusion 26, or the protrusion 26 slides into the groove 35, and the cover 11 is combined with the second cylinder 19 to rotate together.

One end of the cylindrical portion contacts the bottom surface 13 of the cover 11, preventing the wall 20 from further penetrating into the second tube 19. The outer surfaces of the cylindrical portion and the conical portion both extend beyond the outer surface of the cover 11. A diameter 38 on the inner side of the conical portion is larger than the diameter 37 of the first tube 18 (see FIG. 5 ), so the oil core 40 removed by the disassembly tool 10 through the second tube 19 is larger in size or volume than the oil core 40 removed by the disassembly tool 10 through the first tube 18.

Of course, there are other ways to combine the cover 11 and the second tube 19. The grooves 35' on the outer side 22 of the wall 20 respectively receive the protrusions 26' of the cylindrical portion of the second tube 19, so that the cover 11 rotates together with the second tube 19 (refer to Figure 8).

In some embodiments, the L-shaped groove 35" forms the outer side 22 of the wall of the cover 11, receiving the protrusion 26" on the inner side of the cylindrical portion of the second tube 19, so that the cover 11 rotates together with the second tube 19 (refer to Figure 9).

In some embodiments, the protrusion 26" protrudes from the outer side 22 of the wall of the cover 11 and slides into the L-shaped groove 35" recessed in the cylindrical portion of the second tube 19, so that the cover 11 rotates together with the second tube 19 (see Figure 9).

If possible, a driving end (not numbered) of a screwdriver 44 is inserted into the hole 15 to apply torque to the removal tool 10, which can also perform the removal operation of the oil core 40.

As shown in Figures 12 and 13, the second embodiment of the disassembly tool 10 includes: the cover 11, the first tube 18 and a sleeve 16.

In this embodiment, the number of the liner 16 is single. In some embodiments, the number of the liner 16 is multiple, and each has a different size. The liner 16 is a ring, and the outer side of the ring is a multi-faceted structure 31. The inner side of the liner 16 is a multi-faceted structure formed by connecting multiple planes 32. The plane 32 maintains a thickness 33 to the multi-faceted structure 31, so the volume of the space enclosed by the multi-faceted structure is smaller than the volume of the chamber 23.

The bushing 16 is inserted into the interior of the wall 20, and the multi-faceted structure 31 fits each of the planes 25, so that the disassembly tool 10 passes through each of the planes 32 of the bushing 16 to disassemble the oil core 40 which is smaller in volume than the aforementioned one (see Figure 10).

Therefore, the disassembly tool 10 of the present invention has the following advantages:

1. The cap 11 is a common component (assembly). The disassembly tool 10 formed by the cap 11 and the first barrel 18 can disassemble the oil core 40 of moderate size. The disassembly tool 10 formed by the cap 11 and the second barrel 19 can disassemble the oil core 40 of larger volume. The disassembly tool 10 formed by the cap 11 and the bushing 16 can disassemble the oil core 40 of smaller volume.

Second, the volume of the entire disassembly tool 10 is smaller than that of the previous technology, which is convenient for carrying around and for immediately carrying out the disassembly operation of the oil core 40.

3. The manufacturing cost of the whole set of disassembly tools 10 is low, and it is more competitive in the market than the previous technology.

Without departing from the broad concept of this case, those familiar with this technology can understand and make changes to the above-mentioned embodiments. Therefore, this case is not limited to the specific embodiments disclosed in the specification. All modifications made according to the spirit and technical scope of this case should be covered and protected by the text content defined in the scope of the patent application.
