Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an adapter for a rotary tool such as a wrench used for attaching and detaching a nut to fix a wheel such as an aluminum wheel for automobiles to a hub, and more specifically, to an adapter having a nut holding mechanism. is there.

[0002]

[Prior art]

 Wheels, such as aluminum wheels for automobiles, are designed so that the nut mounting position is deep in the nut mounting hole formed on the outer surface of the wheel, specifically, several tens mm to 100 mm, depending on the design and structure. Some are positioned.

[0003] The nut to be fastened at a position deep in the hole when viewed from the outer surface of the wheel, especially when the nut is to be removed, is rotated by a nut such as a wrench equipped with a long socket-type adapter. Although the nut is loosened using a tool, if the nut loosens and comes off the stud bolt of the hub, the nut tends to remain in the hole, making it difficult to remove it.

In view of the above, when an adapter is provided with a nut holding mechanism and the adapter is fitted to the nut, the nut is held by the action of the nut holding mechanism, and the nut detached from the stud bolt does not remain in the hole. That is what is being supplied to the market.

FIG. 6 shows an example of a conventional nut holding mechanism of an adapter. The holding mechanism is provided with a hole 12 formed in a socket main body 11 of the adapter for fitting a nut into a square hole 12. A ball holding hole 13 penetrating the inner surface of the socket body 11 is provided on the outer peripheral surface of the socket body 11, a ball 14 is put into the hole 13, and the ball 14 is pressed and held by a leaf spring 15 wound around the socket body 11. The nut is held in the square hole 12 by a spring force acting on the ball 14. In addition, although not shown, the conventional nut holding mechanism has a structure in which a magnet for sucking and holding the nut is embedded in a square hole for fitting the nut instead of the ball.

However, in the above-mentioned conventional product, it is necessary to form a ball hole 13 in the metal socket main body 11 and form a mounting groove for the plate spring 15 on the outer periphery of the main body 11. Since the work of caulking 15 into the mounting groove of the socket body 11 is also added, it takes time to manufacture and is therefore expensive. In addition, a magnet using a magnet requires a magnet having a large attraction force, and its mounting is not easy. In addition, there are the following inherent problems.

That is, in the adapter formed to cope with the case where the nut position is deep, the square hole 12 is formed long (deep), but when the magnet is embedded in the deep square hole, it is attracted to the magnet. It is extremely difficult or practically impossible to remove such foreign matter such as iron powder, which causes a problem that the foreign matter such as iron powder damages the surface of the nut.

[0008]

[Problems to be solved by the invention]

 In view of the current situation of the adapter with a nut holding function described above, the present invention can easily remove foreign matter such as iron powder even if it is attracted to the magnet, and damage the nut even if foreign matter such as iron powder is attached. It is an object of the present invention to provide an adapter having a nut holding mechanism using a magnet or a magnetic force that does not have any problem.

[0009]

[Means for Solving the Problems]

 The adapter of the present invention made to solve the above problem has a square hole or a prism for coupling to a tip of a tool body such as a wrench on one side and a square hole for nut fitting on the other side. In the formed adapter, a magnetic force is applied to the rear end face of the square hole or prism or in the vicinity of the rear end face, and when the loosened nut remains in the nut mounting hole, the prism or square hole side is used as the nut mounting hole. The present invention is characterized in that the nut remaining after insertion is sucked and taken out by the magnetic force.

[0010]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of an example of the adapter of the present invention, FIG. 2 is a cross-sectional view of a main part of another example, FIG. 3 is a side cross-sectional view of the adapter of FIG. FIG. 5 is a side sectional view of the adapter of FIG. 4, and FIG. 6 is a side sectional view of an example of the conventional adapter.

In FIG. 1, reference numeral 1 denotes a socket body of the adapter according to the present invention, in which the right side is formed on a connecting prism portion 2 for connecting to a tip connecting portion of a nut rotating tool such as a wrench, and the left side. A hexagonal square hole 3 for fitting to a wheel nut (not shown) is formed in the hole. The configuration from the socket body 1 to the nut fitting square hole 3 forms an example of a well-known socket type adapter As. When the tip of the nut rotating tool is a prism, the right side of the adapter As is fitted to the prism of the nut rotating tool in place of the prism 2 as illustrated in FIGS. It is formed in the square hole 21.

In the present invention, the magnet 4 is buried as an example in the prism portion 2 or the square hole portion 21 which is connected to the tip connecting portion (not shown) of the rotary tool in the adapter As described above. The magnet 4 is formed so as to function as a nut holding mechanism. It is preferable that the magnet 4 be formed in a concave shape in accordance with the shape (convex shape) of the head of the nut to be sucked because the suction surface can be enlarged.

The above-described nut holding mechanism is used as follows. That is, the adapter of the present invention is connected to the tip of the rotating tool at the prism 2 or the square hole 21. The socket body 1 is inserted into the nut mounting hole (not shown) of the wheel, and the nut is inserted into the square hole 3. (Not shown) and loosen the nut, but if the nut comes off the stud bolt of the hub, it will come off from the square hole 3 by pulling out the socket body 1 and it will remain in the nut mounting hole. When the socket body 1 pulled out is separated from the rotary tool and the side of the prism 2 or the square hole 21 of the main body is inserted into the nut mounting hole, the socket body 1 is provided in the prism 2 or square hole 21. The nut remaining in the hole is attracted by the attracting force of the magnet 4, so if the socket body 1 is pulled out from the nut mounting hole as it is, the nut will come out together.

In the present invention, the embedding form of the magnet 4 in the prism portion 2 or the square hole portion 21 is not limited to the illustrated example. That is, when the prism portion 2 or the square hole portion 21 is inserted into the nut mounting hole where the nut is left, the magnet may be arranged so as to attract the nut and draw out the magnet together. . The magnet to be buried is not limited to metal, but may be an elastic rubber or plastic material formed on the magnet, and furthermore, at least the rear end face of the prism 2 or the square hole 21 may be magnetized. No.

[0015]

[Effect of the invention]

 The present invention provides a socket-type adapter to be coupled to a rotary tool, in which a prism or square hole serving as a coupling portion is provided with magnetic force, and a nut remaining in a nut mounting hole in a state of being detached from a stud bolt is removed. Since the prism or square hole side of the adapter is inserted into the hole, the nut is sucked out and pulled out, so even if iron powder etc. adheres to the magnet part, it can be easily removed, and The unique effect is obtained that the nut is not damaged even if foreign matter such as powder is not removed.

If the end face of the magnet or the end face of the square hole or prism provided with magnetic force is made concave, or the magnet is made of an elastic rubber or plastic material, the adsorption area can be increased, The advantage of not scratching the nut head is obtained.
