또한, 하기 실시예는 본 발명의 권리범위를 한정하는 것이 아니라 단지 예시로 제시하는 것이며, 본 기술 사상을 통해 구현되는 다양한 실시예가 있을 수 있다.In addition, the following examples are not intended to limit the scope of the present invention but merely presented by way of example, and there may be various embodiments implemented through the present invention.

도 1는 본 발명에 따른 보호캡이 구비된 차량용 휠 너트를 나타낸 사시도이고, 도 2는 본 발명에 따른 보호캡이 구비된 차량용 휠 너트를 나타낸 단면도이며, 도 3는 본 발명에 따른 보호캡이 구비된 차량용 휠 너트에 있어, 휠 너트에 보호캡이 체결되는 과정을 나타낸 도면이다.1 is a perspective view showing a vehicle wheel nut with a protective cap according to the present invention, Figure 2 is a cross-sectional view showing a vehicle wheel nut with a protective cap according to the present invention, Figure 3 is a protective cap according to the present invention In the wheel nut for a vehicle provided, a view showing a process of fastening the protective cap to the wheel nut.

도면에 도시된 바와 같이 본 발명인 보호캡이 구비된 차량용 휠 너트(10)(이하 차량용 휠 너트)는 휠 너트바디(20)와 보호캡(30)으로 구성된다.As shown in the figure, the vehicle wheel nut 10 (hereinafter, the vehicle wheel nut) provided with the protection cap of the present invention includes a wheel nut body 20 and a protection cap 30.

상기 휠 너트바디(20)는 금속재로 이루어지며 공구가 체결되도록 육각의 헤드(21)가 형성되고, 헤드(21)의 단부에는 공구를 지지하도록 걸림턱부(22)가 형성되며, 상기 걸림턱부(22)에는 조임에 의해 휠을 가압하는 테이퍼부(23)가 형성된다.The wheel nut body 20 is made of a metal material, and a hexagonal head 21 is formed to fasten a tool, and a locking jaw portion 22 is formed at an end of the head 21 to support a tool. 22, a taper 23 is formed to press the wheel by tightening.

상기 보호캡(30)은 스테인리스강으로 이루어지며 상기 헤드(21)와 상기 걸림턱부(22)를 감싸면서 상기 휠 너트바디(20)에 끼움되어 체결된다. 이러한 보호캡(30)은 상기 헤드(21)가 끼움되는 고정마개(31)와 상기 걸림턱부(22)가 지지고정되는 걸림부(32)로 이루어진다.The protective cap 30 is made of stainless steel and is fastened to the wheel nut body 20 while surrounding the head 21 and the locking jaw portion 22. The protective cap 30 is composed of a fixing stopper 31 to which the head 21 is fitted and a locking portion 32 to which the locking jaw portion 22 is fixed.

이때, 상기한 보호캡(30)은 도 3에 도시된 바와 같이 상기 휠 너트바디(20)에 끼움된 후 단부가 롤링에 의해 가압,절곡되어 상기 걸림부(32)를 형성시킴으로서, 상기 보호캡(30)이 빠지지않고 상기 걸림턱부(22)에 걸림되게 지지고정된다.At this time, the protective cap 30 is fitted to the wheel nut body 20, as shown in Figure 3, the end is pressed and bent by rolling to form the engaging portion 32, the protective cap 30 is fixed without being pulled out and supported by the locking jaw portion 22.

여기서, 상기 휠 너트바디(20)는 상기 보호캡(30)에 억지끼움되어 고정되게 하는 것도 가능하다.Here, the wheel nut body 20 may be fixed to the protective cap 30 by being fitted.

상기와 같이 구성된 차량용 휠 너트(10)는 휠 너트바디(20)가 아연도금되어 도금층과 휠 사이에 조임력이 점차 약해지지 않으며, 보호캡(30)을 스테인리스강으로 형성시켜 미려한 외관을 제공하고 휠 너트바디(20)의 부식을 방지하게 된다.The wheel nut 10 for the vehicle configured as described above has the wheel nut body 20 galvanized so that the tightening force is not gradually weakened between the plating layer and the wheel, and the protective cap 30 is formed of stainless steel to provide a beautiful appearance and the wheel. The corrosion of the nut body 20 is prevented.

상기에서는 상기 휠 너트바디에는 조임력이 약해지는 것을 방지하기 위해 아연도금하는 것으로 설명하고 있지만, 이에 한정되는 것은 아니며 아연도금 이외에 조임력이 약해 지는 것을 방지하고 휠 너트바디가 미세하게 풀리는 것을 방지하는 도금이면 어느것이 사용되어도 무방하다.
In the above, the wheel nut body is described as being galvanized to prevent the tightening force from being weakened. However, the present invention is not limited thereto, and the wheel nut body is plated to prevent the tightening force from being weakened and to prevent the wheel nut body from loosening. Which may be used.

도 4는 본 발명에 따른 보호캡이 구비된 차량용 휠 너트의 다른 실시예를 나타낸 단면도이다.Figure 4 is a cross-sectional view showing another embodiment of a wheel nut for a vehicle provided with a protective cap according to the present invention.

도 4를 참조하면, 상기에서는 휠 너트바디(20)의 헤드(21)와 걸림턱부(22)가 끼워지도록 보호캡(30)을 체결한 후 단부를 절곡하여 걸림되게 지지고정되는 것으로 설명 및 도면에 나타내고 있지만 이에 한정되는 것은 아니다.Referring to FIG. 4, in the above, after the protective cap 30 is fastened so that the head 21 and the locking jaw portion 22 of the wheel nut body 20 are fitted, the end portion of the wheel nut body 20 is fixed and supported to be locked. Although it is shown to but is not limited to this.

예를들면, 상기 고정마개(31)의 외벽부(311)를 상기 헤드(21)의 외면과 면접촉되도록 다각으로 형성시키되, 상기 외벽부(311)의 각각의 외벽(311a)은 상기 헤드(21)가 억지끼움된 후 가압고정되도록 내측으로 만곡지게 형성시킨다.For example, the outer wall portion 311 of the fixing stopper 31 is formed in a polygonal shape so as to be in surface contact with the outer surface of the head 21, each outer wall 311a of the outer wall portion 311 is the head ( 21) is formed to be curved inward to be pressurized after the interference fit.

즉, 상기 외벽(311a)을 탄성을 갖도록 내측으로 볼록하게 형성시킴으로서, 고정마개(31)에 억지끼움된 헤드(21)가 외벽(311a)의 탄성에 의해 가압고정된다.
That is, by forming the outer wall 311a convex inwardly to have elasticity, the head 21, which is forcibly fitted to the fixing stopper 31, is pressurized and fixed by the elasticity of the outer wall 311a.

도 5a 및 도 5b는 본 발명에 따른 보호캡이 구비된 차량용 휠 너트의 또 다른 실시예를 나타낸 도면이다.5a and 5b is a view showing another embodiment of a wheel nut for a vehicle provided with a protective cap according to the present invention.

도 5a 및 도 5b를 참조하면, 상기에서는 헤드(21)에 보호캡(30)을 끼운 후 걸림부(32)의 단부를 절곡시켜, 걸림턱부(22)에 걸림고정되게 하는 것으로 설명 및 도면에 나타내고 있지만 이에 한정되는 것은 아니다.5A and 5B, in the above description, the protection cap 30 is inserted into the head 21 and the end of the locking portion 32 is bent to lock the locking portion 22. Although shown, it is not limited to this.

예를 들면, 상기 보호캡(30)에 형성된 걸림부(32)의 외면을 가압롤러(도시생략)로 롤링하여 마찰부(321)를 형성시킴과 아울러 내부에 배치된 걸림턱부(22)가 압착고정되어, 휠 너트바디(20)가 보호캡(30)에 재차 가압 고정된다.For example, the outer surface of the locking portion 32 formed on the protective cap 30 is rolled by a pressure roller (not shown) to form a friction portion 321 and the locking jaw portion 22 disposed therein is crimped. It is fixed, the wheel nut body 20 is fixed to the protection cap 30 by pressing again.

이때, 상기 마찰부(321)는 다수의 돌기를 갖는 가압롤러(도시생략)에 의해 롤링되어 형성된 다수의 고정홈으로 이루어진다.
At this time, the friction part 321 is composed of a plurality of fixing grooves formed by rolling by a pressure roller (not shown) having a plurality of protrusions.
