Description

철근결속용 회전구{ROTARY DEVICE FOR BINDING IRON ROD}ROTARY DEVICE FOR BINDING IRON ROD}

본 발명은 철근결속용 회전구의 개량에 관한 것으로서, 특히 결속봉과 손잡이의 조립이 신속용이하면서 견고하게 함과 동시에 손잡이를 다이캐스팅으로 성형하여 미려한 외관유지와 생산성 향상 효과를 기대할 수 있도록 한 것이다.The present invention relates to an improvement of a revolving fastener for reinforcing bars, and in particular, the assembly of the binding rod and the handle is quick and easy, and at the same time, the handle is formed by die casting so that a beautiful appearance and productivity improvement effect can be expected.

철근결속용 회전구에 대하여서는 본 고안의 출원인이 선출원하여 등록된 것들이 있다.Regarding the rotary ball for reinforcing bars, there are those registered in advance by the applicant of the present invention.

한예로서 실용신안등록 제286504호 "철근결속용 회전구"가 있다.As an example, there is a utility model registration No. 286504 "rotator for binding bars."

상기 철근결속용 회전구는 결속봉의 하부몸체 단부에 걸림부 및 요입홈을 구성하고, 상기한 구성의 결속봉을 손잡이의 내면중공부에 끼워 걸림부 및 요입홈이 확장공내에 위치되게 한 다음 와샤와 스톱링을 끼워 스톱링이 요입홈에 끼워져 결합되게 한 통상의 철근결속용 회전구를 구성함에 있어서, 손잡이의 내면 일측에 구성된 확장공의 벤딩부에 원형고리가 연결된 지지체를 끼워 지지체가 걸림턱에 걸려 고정되게 하고, 상기 벤딩부 외면을 가압벤딩하여 손잡이 일측에 원형고리가 형성된 지지체가 일체형으로 결속되게 하고, 또한 결속봉의 하부몸체 단부에 구성된 걸림부에는 경사면이 구성되게 하여 스톱링의 결속이 용이하게 이루어지도록 한 것이다.The reinforcing rod for the reinforcing bar constitutes the engaging portion and the recessed groove in the lower body end of the binding rod, and the binding rod of the above configuration is inserted into the inner hollow portion of the handle so that the engaging portion and the recessed groove are positioned in the expansion hole, and In constructing a conventional reinforcing bar for turning the stop ring by inserting the stop ring into the recessed groove, the support is connected to the locking jaw by inserting a support having a circular ring connected to the bending part of the expansion hole formed on one side of the inner surface of the handle. To be fixed, to bend the outer surface of the bending portion to form a unitary support with a circular ring formed on one side of the handle, and to engage the stopper formed at the lower body end of the binding rod so that the engagement of the stop ring is easy. It is to be done.

따라서 상기한 구성의 회전결속구는 손잡이내에 결속봉을 회전이 자유롭게 구성하되, 손잡이 일측 단부에 구성된 원형고리가 결속봉과는 분리되게 구성하여 결속봉의 회전에도 원형고리는 회전되지 않게 하여 작업자가 손잡이의 끝부분을 잡고 결속작업을 하더라도 작업에 아무런 불편이 없도록 함과 동시에 손잡이를 금속재질로 성형하여 결속된 철선의 마무리 절곡작업시 손잡이로 두드려 절곡가능케 하므로서 마무리 작업이 용이하게 이루어질 수 있게 되는 등의 효과가 있는 것이었으나 다음과 같은 작업상 어려움도 있는 것이었다.Therefore, the rotating fastener of the above configuration is configured to freely rotate the binding rod in the handle, the circular ring configured at one end of the handle is configured to be separated from the binding rod so that the circular ring does not rotate even when the binding rod is rotated so that the operator ends the handle. Even if you hold the parts and bind them, there is no inconvenience to work, and at the same time, the handles are made of metal, and the finishing work of the bound wire can be done by tapping on the handles to make the finishing work easier. However, there were difficulties in the following work.

즉 결속봉을 손잡이에 회전이 자유롭게 결속하기 위한 수단으로서 결속봉의 하부몸체단부에 요입홈과 경사면이 형성된 걸림부를 구성한 다음 상기한 구성의 결속봉을 손잡이의 중공부에 끼워 결속봉의 걸림부가 중공부 일측에 구성된 확장공내에 위치되게 한다.That is, as a means for freely binding the binding rod to the handle, a locking portion having a recessed groove and an inclined surface is formed at the lower body end of the binding rod. It is to be located in the expansion hole configured at.

상기한 상태에서 손잡이의 확장공에 스톱링을 끼워 걸림부에 구성된 경사면과 접하게 하고, 상기한 상태에서 스톱링을 타압하여 스톱링이 확장되면서 경사면을 따라 이동하여 결속봉의 요입홈에 끼워져 결합되게 하므로서 결속봉이 손잡이의 중공부내에 결속완료되게 한 것이다.In the above state, the stop ring is inserted into the expansion hole of the handle so as to be in contact with the inclined surface formed in the engaging portion, and in the above state, the stop ring is extended so that the stop ring is extended and moved along the inclined surface to be fitted into the recess groove of the binding rod. The binding rod is to be completed in the hollow portion of the handle.

그러나 상기에서와 같이 스톱링이 결속봉의 요입홈에 끼워지게 하기 위하여 스톱링을 한정된 공간으로 된 확장공에 위치하는 걸림부의 경사면에 위치시킨 다음 스톱링을 타압할 때 스톱링의 탄지력이 강하면 요입홈에 쉽게 결합되지 못하게 되므로 작업에 어려움이 있고, 상기와는 반대로 스톱링의 결합을 쉽게 하기 위하여 탄지력을 약하게 할 경우에는 사용 중 결속봉의 요입홈으로부터 스톱링이 이탈하게 되는 문제가 있는 것이었다.However, in order to make the stop ring fit into the recessed groove of the binding rod as described above, if the stop ring is strong when pressing the stop ring, It is difficult to work because it is not easily coupled to the mouth groove, contrary to the above, when weakened the grip force to facilitate the coupling of the stop ring, there was a problem that the stop ring is separated from the recess groove of the binding rod during use.

또한 결속봉의 일측 단부에 구성되는 요입홈이나 걸림부에 구성된 경사면의 작업은 선반으로 가공하여야 하므로서 선반가공작업에 많은 어려움이 따르게 되고 상기한 문제이외에도 손잡이 제조시 중공부의 내경이 동일하게 구성되어 있어 작업에 어려움이 따르게 되는 등의 단점이 있는 것이었다.In addition, the work of the inclined surface formed in the indentation groove or the engaging portion configured at one end of the binding rod must be processed into a lathe, which causes a lot of difficulties in lathe processing work, and in addition to the above problems, the inner diameter of the hollow part is the same when manufacturing the handle. There was a disadvantage, such as to be followed.

본 발명은 이러한 종래의 제반단점을 시정하고자 결속봉을 손잡이내에 회전이 자유롭게 결합구성된 철근결속용 회전구를 구성하되, 결속봉과 손잡이의 결속작업이 신속용이할 뿐 아니라 견고하게 하고 또한 손잡이를 금속다이캐스팅으로 제조하되, 중공부의 선단부와 후단부에 구성되는 내경이 달라지더라도 사용에 문제가 없도록 한 것이다.The present invention constitutes a reinforcing bar for fastening the binding rod freely coupled to the handle in order to correct the above-mentioned general disadvantages, the fastening operation of the binding rod and the handle is not only quick and robust but also the metal die casting handle It is manufactured as, but there is no problem in use even if the inner diameter consisting of the front end and the rear end of the hollow portion is different.

상기 목적을 달성하기 위하여 본 발명은 다이캐스팅으로 성형된 손잡이의 중공부내에 결속봉을 끼워 결속봉의 후단부가 손잡이 후단부에 구성된 확장부에 위치되게 하고, 동시에 확장부내에 위치하는 결속봉 후단부에 확장부의 내경과 일치하는 지지링을 끼운다음 지지링을 관통한 결속봉의 단부를 가압가공하여 리벳 머리형태의 걸림부를 구성하므로서 걸림부가 지지링에 걸려 이탈되지 않게 하고, 상기 지지링은 중공부의 단턱에 걸려 이탈되지 않게 하여서 된 것이다.In order to achieve the above object, the present invention inserts the binding rod into the hollow portion of the handle formed by die-casting so that the rear end of the binding rod is positioned at the extension configured at the rear end of the handle, and at the same time is extended to the rear end of the binding rod located in the extension portion. Insert a support ring that matches the inner diameter of the part, and pressurize the end of the binding rod that penetrates the support ring to form a rivet head-shaped locking part so that the locking part is not caught by the support ring, and the support ring is caught by the step of the hollow part. It was made so as not to stray.

이하 본 발명의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

먼저 손잡이(300)의 중공부(310)내에 결합되는 결속봉(200)은 절곡부(230)를 기준으로 하부몸체(210)와 상부몸체(220)로 구분 구성되며 상부몸체(220) 선단부에는 통상의 걸림고리부(221)가 구성되어 잇고 하부몸체(210)의 후단부(211)는 금속봉체가 절단된 상태로 구성되어 있다.First, the binding rod 200 coupled to the hollow portion 310 of the handle 300 is divided into a lower body 210 and an upper body 220 based on the bent portion 230, and an upper end of the upper body 220. The general hook ring portion 221 is configured and the rear end portion 211 of the lower body 210 is configured in a state where the metal rod is cut.

상기 결속봉(200)의 하부몸체(210)가 끼워져 결합되는 손잡이(300)는 다음과 같이 구성된다.The handle 300 to which the lower body 210 of the binding rod 200 is fitted is coupled as follows.

금속소재를 이용하여 다이캐스팅방법으로 손잡이(300)를 성형하되, 다이캐스팅작업이 용이하도록 내면에 구성되는 중공부(310)가 선단부(311)는 좁고 후단부(312)는 선단부(311)보다 조금 더 넓게 하여 다이캐스팅작업이 용이하게 하되, 상기 중공부(310)의 후단부(312) 일측에는 확장부(313)를 구성한다.Molding the handle 300 by a die casting method using a metal material, the hollow portion 310 is formed on the inner side to facilitate the die casting operation, the front end 311 is narrow and the rear end 312 is slightly more than the front end 311 The die casting operation is facilitated by making it wider, and an extension part 313 is formed at one side of the rear end part 312 of the hollow part 310.

상기 확장부(313) 내면에는 단턱(314)과 걸림턱(315)을 구성하되 걸림턱 (315) 외측면에는 벤딩부(316)가 구성되게 하고, 손잡이(300) 외면에는 요철부 (301)를 구성하여 손잡이(300)의 파지가 용이하도록 하였다.The expansion part 313 is formed on the inner surface of the stepped jaw 314 and the locking jaw 315 but the outer surface of the locking jaw 315 is configured to be a bending portion 316, the handle 300, the outer surface of the uneven portion 301 It was configured to facilitate the grip of the handle 300.

상기한 구성의 손잡이(300)내면 중공부(310)에 결속봉(200)의 하부몸체(210)를 끼워 하부몸체(210)의 후단부(211)가 확장공(313)내에 위치되게 한다.The rear end portion 211 of the lower body 210 is inserted into the expansion hole 313 by fitting the lower body 210 of the binding rod 200 to the inner surface hollow portion 310 of the handle 300.

확장공(313)내에 위치하는 결속봉(200)의 하부몸체(210) 외면에 지지링(317)을 끼운다.The support ring 317 is fitted to the outer surface of the lower body 210 of the binding rod 200 located in the expansion hole 313.

이때 지지링(317)의 내경은 결속봉(200)의 하부몸체(210)에 구성된 후단부 (211)의 외경과 거의 일치되게 하고, 외경은 확장부(313)의 내경과 일치되게 하므로서 지지링(317)이 확장부(313)의 단턱(314)에 걸려 고정되게 한다.At this time, the inner diameter of the support ring 317 is substantially matched to the outer diameter of the rear end 211 configured in the lower body 210 of the binding rod 200, the outer diameter is made to match the inner diameter of the expansion portion 313 while supporting ring 317 is hooked to the step 314 of the extension 313 to be fixed.

상기한 상태에서 결속봉(200)의 상부몸체(220) 부분을 선반에 고정시킨 다음 손잡이(300)의 확장부(313)내에 위치하는 결속봉(200)의 후단부(211)를 리벳머리작업방식으로 가압가공하여 원호형의 걸림부(222)를 구성하므로서 걸림부(222)에 의해 결속봉(200)의 하부몸체(210)가 지지링(317)에 걸려 이탈되지 않게 하고, 상기 지지링(317)은 다시 확장부(313)의 단턱(314)에 걸려 지지되게 하므로서 결속봉(200)이 손잡이(300)내에 회전이 자유롭게 결합고정되게 한다.In the above state, the upper body 220 of the binding rod 200 is fixed to a shelf, and then the rear end 211 of the binding rod 200 located in the extension 313 of the handle 300 is riveted to the head work. By pressurizing in a manner to configure the arc-shaped locking portion 222 so that the lower body 210 of the binding rod 200 is not caught by the support ring 317 by the locking portion 222 is not detached, the support ring 317 is to be supported by the step 314 of the expansion unit 313 again, so that the binding rod 200 is freely coupled and fixed in the handle 300.

이때 손잡이(300) 내면에 구성된 중공부(310)의 선단부(311) 내경은 결속봉 (200)의 외경과 거의 일치되게 하고, 후단부(312)의 내경은 결속봉(200)의 외경보다 크게 구성되어 있으나 후단부(211)가 끼워진 지지링(317)의 외경이 확장부(313)의 내경과 일치하고, 또한 지지링(317)의 내경이 결속봉(200)의 후단부 외경과 일치하게 구성되어 있어 손잡이(300) 내에서 결속봉(200)을 회전시키더라도 유동없이 원활한 결속작업이 가능하게 된다.At this time, the inner diameter of the distal end portion 311 of the hollow portion 310 formed on the inner surface of the handle 300 is substantially coincident with the outer diameter of the binding rod 200, and the inner diameter of the rear end portion 312 is larger than the outer diameter of the binding rod 200. Although the outer diameter of the support ring 317 into which the rear end 211 is fitted coincides with the inner diameter of the expansion part 313, the inner diameter of the support ring 317 coincides with the outer diameter of the rear end of the binding rod 200. It is configured so that even when the binding rod 200 is rotated within the handle 300, the smooth binding operation without flow.

상기에서와 같이 손잡이(300)의 중공부(310) 내에 결속봉(200)의 결합이 완료되면 확장부(313) 내측에 통상의 방법과 같이 고리(331)가 형성된 지지체(330)를 끼워 지지체(330)가 걸림턱(315)에 걸려 고정되게 하고, 동시에 벤딩부(316)를 벤딩하여 절곡하므로서 손잡이(300) 후단부에 지지체(330)가 결속고정되게 하여서 된 것이다.When the coupling of the binding rod 200 is completed in the hollow portion 310 of the handle 300 as described above, the support 330 is inserted into the extension 313 inside the support 330 in which the ring 331 is formed in a conventional manner. The support 330 is fixed to the rear end of the handle 300 by bending and bending the bending part 316 while the 330 is fixed to the locking jaw 315.

이와 같이 구성된 본 발명은 철근결속용 회전구(100)를 이용하여 철근결속작업을 하고자 할 때 작업자가 손잡이(300)를 잡고 철근결속작업을 위하여 결속봉(200)을 회전시킬 경우 손잡이(300) 후단부에 구성된 걸림고리(331)가 손잡이(300)와 일체형으로 체결고정되어 있고, 결속봉(200)의 하부몸체(210)와는 분리구성되어 있어 결속봉(200)만 회전이 되므로 철근의 결속작업이 용이하게 이루어지게 된다는 것은 종래와 같다.In the present invention configured as described above, the worker 300 grabs the handle 300 and rotates the binding rod 200 for the reinforcing bar binding operation when the reinforcing bar binding work is performed using the reinforcing bar 100 for the reinforcing bar handle 300. The hook 331 configured at the rear end is fastened and fixed integrally with the handle 300, and is separated from the lower body 210 of the binding rod 200 so that only the binding rod 200 is rotated, thereby binding the reinforcing bars. The operation is easily made as in the prior art.

그러나 본 발명에서 제공하고자 하는 철근결속용 회전구(100)는 손잡이(300)와 결속봉(200)의 결합작업이 신속용이하면서 견고하고, 또한 원활한 다이캐스팅작업을 위하여 손잡이(300) 내면에 구성되는 중공부(310)를 경사지게 구성하더라도 사용에 아무런 문제가 없도록 한 것이다.However, the reinforcing bar for the reinforcing bar 100 to be provided in the present invention is fast and easy to combine the handle 300 and the binding rod 200, and is configured on the inside of the handle 300 for a smooth die casting operation Even if the hollow part 310 is inclined, there is no problem in use.

즉 손잡이(300)와 결속봉(200)의 결합수단으로서 결속봉(200)의 하부몸체 (210)를 손잡이(300)의 중공부(310)에 끼워 하부몸체(210)의 후단부(211)가 손잡이 (300)의 확장부(313)내에 위치되게 하고, 확장부(313)에 위치한 하부몸체 (210)의 후단부(211)에 지지링(317)을 끼워 단턱(314)에 걸려지게 한 다음 결속봉(200)을 선반에 고정하고, 상기한 상태에서 후단부(211)를 리벳머리가공방식으로 가압가공하여 지지링(317) 외측에 걸림부(222)를 구성하는 간단한 작업으로 결속봉(200)이 손잡이(300)내에 회전이 자유롭게 결합된다.That is, the rear end portion 211 of the lower body 210 by inserting the lower body 210 of the binding rod 200 into the hollow portion 310 of the handle 300 as a coupling means of the handle 300 and the binding rod 200. Is positioned in the extension 313 of the handle 300, the support ring 317 is fitted to the rear end 211 of the lower body 210 located in the extension 313 to be caught on the step 314. Next, the binding rod 200 is fixed to the shelf, and in the above state, the rear end portion 211 is pressurized by a rivet head processing method to form a locking rod 222 on the outside of the support ring 317. Rotation 200 is freely coupled to the handle 300.

또한 손잡이(300)내에 구성되는 중공부(310)의 선단부(311) 내경보다 후단부 (312)의 내경이 좀더 크게 구성되어 있어 다이캐스팅작업이 원활하게 이루어지게 된다.In addition, since the inner diameter of the rear end portion 312 is larger than the inner diameter of the front end portion 311 of the hollow portion 310 formed in the handle 300, the die casting operation is performed smoothly.

이상 설명한 바와 같이 본 발명은 손잡이내에 결속봉의 회전이 자유롭게 구성된 철근결속용 회전구를 구성하되 결속봉과 손잡이의 결속작업이 신속용이하면서 견고하게 하므로서 생산성 및 상품성을 향상시키고, 또한 용이한 다이캐스팅 작업을 위하여 일측중공부의 내경이 좀더 크게 하더라도 확장부에 끼워진 지지링으로 결속봉의 후단부를 유동없이 지지되게 하므로서 사용에 아무런 장애가 되지 않게 되는 등의 효과가 있는 것이다.As described above, the present invention constitutes a reinforcing bar for rotating reinforcing bars freely configured to rotate the binding bar in the handle, thereby improving productivity and commerciality by making the binding work between the binding bar and the handle quick and easy, and also for easy die casting.
