It relates to a length adjusting device for the pipe member that can be fixed by adjusting the length of the pipe.

통상 파이프 부재로 이루어진 등산용 지팡이, 낚싯대, 커튼 및 빨래 건조대 행거, 그밖에 산업용 장치의 지지대 등은 다단으로 직경이 다른 원통형 파이프를 연속하여 결속시킨 다음 내부에 결합된 길이조절수단에 의해 각각 그 길이를 신장/축소시키면서 사용하도록 되어 있다. Climbing canes, fishing rods, curtains and clothes rack hangers, and other supports of industrial devices, which are usually made of pipe members, are continuously joined by length-adjusting means coupled to each other by continuously binding cylindrical pipes of different diameters in multiple stages. It is intended to be used while shrinking.

상기와 같은 길이조절수단은, 통상 고정봉에 길이를 신장할 수 있는 신장봉이 삽입결합되며, 이 신장봉의 선단에는 고정수단이 결합되어 소정 길이로 조정 후 조절나사를 회전시키게 되면 고정수단이 고정봉의 내주면에 지지고정됨으로써 그 길이를 조절할 수 있게 된다. The length adjustment means as described above, the extension rod that can be extended to the fixed rod is usually inserted and coupled to the tip of the extension rod is fixed to the fixed length after the adjustment means are coupled to the fixed length of the fixing rod is fixed rod By fixing to the inner circumferential surface it is possible to adjust the length.

일 예로써, 한국 등록특허공보 제10-0687175호(낚싯대용 길이조절장치)에서 상기 고정수단은 일측에 신장봉과 결합되는 지지부를 가지는 조절나사를 구비하며 다른 일측으로 조절나사의 작동에 따른 상호 결합에 의해 일단의 절개편이 확개되며 고정봉의 내주면에 밀착고정되는 구조가 개시된 바 있다. As an example, in the Republic of Korea Patent Publication No. 10-0687175 (length adjusting device for fishing rods), the fixing means is provided with a control screw having a support coupled to the extension rod on one side and mutual coupling according to the operation of the adjustment screw to the other side By one end of the cut piece is expanded and has been disclosed a structure that is fixed close to the inner peripheral surface of the fixed rod.

그러나, 이러한 길이조절장치는 상기 고정수단의 고정봉에 지지되는 면이 가압부재의 일단부 외주면으로만 편중되어 고정시에 그 지지력이 견고하지 못해 충격이 여러 번 가해지면 고정이 해제되어 버리는 문제가 있으며, 또한 고정 후에는 고정봉 내 지지면적이 아주 작기 때문에 고정봉 및 신장봉의 결합공차 유격에 의한 신장봉의 결합되지 않은 단부가 좌우 유동이 있는 문제가 있었다.However, such a length adjusting device has a problem that the surface supported by the fixing rod of the fixing means is biased only to the outer peripheral surface of one end of the pressing member, so that the holding force is not firm at the time of fixing, and the fixing is released when the impact is applied several times. In addition, since the fixing area in the fixed rod is very small after the fixing, there is a problem that the left and right ends of the extension rod are not coupled by the clearance gap between the fixing rod and the extension rod.

또한, 상기 고정수단의 조임시 가압부재는 외면이 밋밋한 면으로 되어 고정봉과 조립되는 공차에 의해 헛도는 문제가 있으며, 이에 조임시 고정이 원활하지 못한 단점이 있다. In addition, the pressing member when tightening the fixing means has a flat outer surface, there is a problem in vain due to the tolerance to be assembled with the fixing rod, there is a disadvantage that the fixing is not smooth when tightening.

본 발명은 상기 문제점을 해소하기 위해 발명한 것으로, 상기 고정수단의 양단에 절개편을 구성하여 고정봉 내 길이방향 소정구간에 걸쳐 두 곳에 확개 지지되도록 함으로써 견고한 지지력을 얻을 수 있으며, 고정수단에 결합되는 신장봉도 고정봉과의 공차 유격에 상관없이 좌우 유동이 전혀 없도록 하고 또 고정수단의 외면에 고정봉 내면과 밀착되는 접촉날개를 형성하여 조임시 헛도는 일이 없이 안정된 조임을 이룰 수 있도록 하는 파이프 부재용 길이조절장치를 제공함에 그 목적이 있다.The present invention has been invented to solve the above problems, by forming a cut piece on both ends of the fixing means to be securely supported in two places over a predetermined length in the fixed rod in the fixed rod can be obtained a firm holding force, coupled to the fixing means The extension rod also has no left and right flow, regardless of the clearance gap with the fixed rod, and a contact wing that is in close contact with the inner surface of the fixed rod is formed on the outer surface of the fixing means to achieve a stable tightening without waste. The object is to provide a length adjusting device for the member.

상기 목적을 달성하기 위해 본 발명의 파이프 부재용 길이조절장치는 아래의 구성을 갖는다.In order to achieve the above object, the length adjusting device for a pipe member of the present invention has the following configuration.

고정봉 및 고정봉에 삽입결합되어 길이를 신장할 수 있는 신장봉, 신장봉 선단에 결합되며 신장봉과 결합된 조절나사의 회전작동에 의해 일단에 형성된 절개편이 확개되며 고정봉 내면에 지지토록 된 고정수단을 구비한 파이프 부재용 길이조절장치에 있어서,It is coupled to the fixed rod and the fixed rod, which can be extended to the extension rod and the extension rod, and the cut pieces formed at one end by the rotation of the adjusting screw combined with the extension rod are expanded and fixed to support the inside of the fixed rod. In the length adjusting device for pipe members provided with a means,

상기 고정수단은 상하 관통홀을 가진 몸체 양단에 대칭형의 내주 경사면 및 외측으로부터 절개된 절개편이 형성되고 상측 경사면에는 가이드 돌기, 관통홀의 중간부에는 제1나사산이 형성된 가압부재와,The fixing means has a symmetrical circumferential inclined surface and an incision cut out from the outside on both ends of the body having upper and lower through holes, a guide protrusion on the upper inclined surface, and a pressing member having a first screw thread formed in the middle of the through hole;

외면을 하향 경사지게 형성하여 상기 가압부재의 상측 경사면에 결합시키되 중앙 관통된 내주면에 제2나사산이 형성되고 외면에 상기 가이드 돌기와 결합되는 수직의 가이드 홈이 형성된 하강부재와,A descending member having an outer surface inclined downward to be coupled to an upper inclined surface of the pressing member, wherein a second screw thread is formed on the inner circumferential surface of the center and a vertical guide groove formed on the outer surface to be coupled to the guide protrusion;

중앙관통홀을 가지며 외면을 상향 경사지게 형성하여 상기 가압부재의 하측 경사면에 결합시키는 승강부재와,An elevating member having a central through hole, the outer surface of which is inclined upwardly and coupled to the lower inclined surface of the pressing member;

하부는 신장봉에 결합되는 지지부가 형성되며 상부는 상기 승강부재 및 가압부재를 관통하되 상기 제1,2나사산에 차례로 결합되는 조절나사로 이루어진다.A lower portion is formed with a support portion coupled to the extension rod, and an upper portion is formed of an adjustment screw which passes through the elevating member and the pressing member and is coupled to the first and second screw threads in turn.

이때, 상기 가압부재의 상하 절개편 사이 외주면에는 수직으로 형성된 접촉날개가 방사형으로 다수 배열된다.At this time, the outer peripheral surface between the upper and lower incision piece of the pressing member is arranged in a plurality of radially formed contact wings.

또한, 상기 가압부재에 형성되는 제1나사산의 직경은 제2나사산보다 크게 형성하되 이에 결합되는 조절나사의 직경도 이에 대응되게 2단으로 구성하여 결합하고, 조절나사의 회전시 하강부재가 승강부재보다 회전비가 높게 한다.In addition, the diameter of the first screw thread formed on the pressing member is formed larger than the second screw thread, but the diameter of the control screw coupled thereto is also configured in two stages corresponding to this, and the lowering member is a lifting member when the adjustment screw is rotated. The turn ratio is made higher.

또한, 바람직하게 상기 승강부재는 조절나사의 지지부 상측에 일체로 형성한다.In addition, the lifting member is preferably formed integrally on the upper side of the support of the adjustment screw.

상기 구성에 의해 본 발명은, 고정수단의 양단에 형성된 절개편이 조절나사의 회동에 의해 동시에 확개되며 고정봉 내에 고정되므로써 고정봉에 신장봉을 견고하게 지지 고정시킬 수 있는 효과가 있다.According to the above configuration, the present invention has the effect that the cutting pieces formed at both ends of the fixing means are simultaneously expanded by the rotation of the adjusting screw and fixed in the fixing rod so that the extension rod can be firmly supported and fixed to the fixing rod.

또한, 상기 절개편이 고정봉의 내주면 길이방향 소정구간에 걸쳐 지지력을 확보할 수 있으므로 고정수단에 결합된 신장봉은 고정봉과의 공차유격에 관계없이 좌우 유동이 전혀 없게 되는 효과가 있다.In addition, since the incision piece can secure the bearing force over a predetermined section in the longitudinal direction of the inner circumferential surface of the fixing rod, the extension rod coupled to the fixing means has no effect of left and right flow at all regardless of the clearance gap with the fixing rod.

또한, 상기 접촉날개를 구성함으로써 신장봉의 회전시 고정수단이 고정봉 내에서 고정되어 있게 되므로 원활한 조임을 할 수 있는 효과가 있다.In addition, since the fixing means is fixed in the fixed rod during rotation of the extension rod by configuring the contact wing has an effect that can be smoothly tightened.

또한, 상기 조절나사를 2단으로 구성하여 하강부재가 승강부재보다 회전비가 높게 함으로써 빠른 조임과 풀림을 유도할 수 있는 효과가 있다. In addition, by configuring the adjusting screw in two stages, the lowering member has a higher rotation ratio than the elevating member, thereby inducing fast tightening and loosening.

상기와 같은 본 발명이 적용된 실시예를 첨부된 도면을 참조하여 상세히 설명한다.An embodiment to which the present invention as described above is applied will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 의한 파이프 부재용 길이조절장치의 분해사시도, 도 2는 본 발명에 의한 파이프 부재용 길이조절장치의 분해단면도, 도 3은 도 2의 결합단면도를 각각 도시하고 있다.1 is an exploded perspective view of a pipe member length adjusting device according to the present invention, FIG. 2 is an exploded cross-sectional view of a pipe member length adjusting device according to the present invention, and FIG.

도면을 참조하면, 고정봉(10) 및 고정봉(10)에 삽입결합되어 길이를 신장할 수 있는 신장봉(20), 신장봉 선단에 결합되며 신장봉과 결합된 조절나사(70)의 회전작동에 의해 일단에 형성된 절개편이 확개되며, 고정봉 내면에 지지토록 된 고정수단(30)을 구비한 파이프 부재용 길이조절장치는 종래의 구성과 유사하다.Referring to the drawings, the fixed rod 10 and the rod 10 is inserted and coupled to the extension rod 20 that can be extended in length, coupled to the extension rod tip and rotation operation of the adjustment screw 70 coupled to the extension rod The cutting piece formed at one end is expanded, and the length adjusting device for the pipe member having the fixing means 30 supported on the inner surface of the fixing rod is similar to the conventional configuration.

그러나 본 발명은 이에 대한 기존 구성의 문제를 해결하기 위한 것으로, 특히 상기 고정수단(30)에 있어서 견고한 지지력을 확보할 수 있고, 또한 이에 따른 조임 고정시 안정성 및 조임 고정 후 견고한 지지력 및 지지면적에 따른 고정봉에서의 신장봉의 유동을 전혀 없도록 하는데 그 주안점을 둔 것이다.However, the present invention is to solve the problem of the existing configuration for this, in particular, it is possible to secure a solid support force in the fixing means 30, and accordingly to the stability and tightening capacity and tightness after tightening fastening accordingly The main focus is to ensure that there is no flow of the extension rod in the fixed rod.

이를 위한, 본 발명의 상기 고정수단(30)은 크게 가압부재(40)와 하강부재(50)와 승강부재(60)와 조절나사(70)로 대별되어 진다.To this end, the fixing means 30 of the present invention is largely divided into a pressing member 40 and the lowering member 50, the elevating member 60 and the adjustment screw 70.

상기 가압부재(40)는 상하 관통홀(41)을 가진 몸체 상하 양단에 대칭형의 내주 경사면(42a,42b)을 가지며, 외측으로부터는 절개된 절개편(43a,43b)이 형성되어 있고, 상측 경사면(42a)에는 가이드 돌기(44)가 형성되며, 상기 관통홀(41)에는 제1나사산(45)이 형성되어 있다.The pressing member 40 has symmetrical inner circumferential inclined surfaces 42a and 42b at upper and lower ends of the body having upper and lower through-holes 41, and incisions 43a and 43b cut out from the outside are formed, and upper inclined surfaces. A guide protrusion 44 is formed at 42a, and a first screw thread 45 is formed at the through hole 41.

이때, 상기 상측 경사면(42a)은 상광하협의 경사면을 이루며 하측 경사면(42b)은 하광상협의 경사면을 가지게 되며, 상기 상하 절개편(43a,43b)은 상하단에서 일정길이 절개되어 바람직하게 각 4개의 편을 이루고 있다. At this time, the upper inclined surface (42a) forms an inclined surface of the upper light lower narrow, and the lower inclined surface (42b) has an inclined surface of a lower light upper narrow, the upper and lower cut pieces (43a, 43b) are preferably cut at a predetermined length from the upper and lower ends, respectively Is on the side.

한편, 상기 가압부재(40)의 상하 절개편(43a,43b) 사이 외주면에는 수직으로 형성된 접촉날개(46)가 방사형으로 다수 배열되어 있다.On the other hand, on the outer circumferential surface between the upper and lower cutting pieces 43a, 43b of the pressing member 40, a plurality of vertical contact wings 46 are arranged radially.

여기에서 상기 고정봉(10)에 내입 결합되는 절개편(43a,43b)의 외경은 고정봉(10)과의 끼움에 따른 직경이 작게 공차를 이루지만, 상기 접촉날개(46)는 그 외경이 고정봉(10)과는 공차가 없는 것으로 상호 결합시 접촉날개(46)가 고정봉(10) 내측에 밀착 결합된다. Here, the outer diameters of the cutting pieces 43a and 43b that are in-coupled to the fixing rod 10 have a smaller diameter due to the fitting with the fixing rod 10, but the contact wing 46 has an outer diameter. As there is no tolerance with the fixing rod 10, the contact wings 46 are tightly coupled to the inside of the fixing rod 10 at the time of mutual coupling.

이를 원활히 하기 위해 상기 접촉날개(46)의 각 상단 외측면은 하향경사지게 모따기를 해주는 것이 바람직하다 할 것이다.In order to facilitate this, it is preferable that each top outer surface of the contact wing 46 be chamfered downwardly.

상기 하강부재(50)는 외면을 하향 경사지게 형성하여 상기 가압부재(40)의 상측 경사면(42a)에 결합시키되, 중앙 관통된 내주면에 제2나사산(51)이 형성되고 외면에 상기 가압부재(40)의 가이드 돌기(44)와 결합되는 수직의 가이드 홈(52)이 형성된다. The lower member 50 is formed to be inclined downward to the outer inclined surface (42a) of the pressing member 40, the second screw thread 51 is formed on the inner circumferential surface through the center and the pressing member 40 on the outer surface The vertical guide groove 52 is coupled to the guide protrusion 44 of the) is formed.

이에 상기 가이드 홈(52)에 가이드 돌기(44)가 체결됨으로서 추후 나사조임에 따라 하강부재(50)는 자체 회전하지 않고 가압부재(40)의 하측으로만 이동하며 절개편(43a)을 확개시키게 된다.Accordingly, the guide protrusion 44 is fastened to the guide groove 52 so that the lowering member 50 does not rotate by itself and moves only to the lower side of the pressing member 40 as the screw is tightened later, thereby expanding the cutting piece 43a. do.

상기 승강부재(60)는 중앙 관통홀(61)을 가지며 외면을 상향 경사지게 형성하여 상기 가압부재의 하측 경사면(42b)에 결합되며, 상향시 가압부재의 하측 절개 편(43b)을 확개시키게 된다.The elevating member 60 has a central through hole 61 and is formed to be inclined upwardly on the outer surface thereof to be coupled to the lower inclined surface 42b of the pressing member, thereby expanding the lower cutting piece 43b of the pressing member when upward.

한편, 상기 조절나사(70)는 하부는 신장봉(20)에 결합되는 지지부(71)가 형성되며 상부는 상기 승강부재(60) 및 가압부재(40)를 관통하되 상기 제1,2나사산(45,51)에 차례로 결합되어, 회전 조임에 따라 승,하강부재를 가압부재의 중심쪽으로 조여주게 된다.On the other hand, the adjustment screw 70 is formed in the lower portion is the support portion 71 is coupled to the extension rod 20 and the upper portion passes through the elevating member 60 and the pressing member 40, the first and second screw thread ( 45, 51) in turn, tighten the lifting and lowering member toward the center of the pressing member in accordance with the rotational tightening.

이때, 상기 가압부재(40)에 형성되는 제1나사산(45)의 직경은 상기 하강부재(50)의 제2나사산(51)보다 크게 형성하되, 이에 결합되는 조절나사의 직경도 이에 대응되게 2단의 나사산(72a,72b)으로 구성하여 결합하고, 조절나사의 회전시 하강부재(50)가 승강부재(60)보다 회전비가 높게 하는 것이 더 바람직하며, 또한 상기 승강부재(60)는 조절나사의 지지부(71) 상측에 일체로 형성되는 것이 바람직하다.At this time, the diameter of the first screw thread 45 formed in the pressing member 40 is larger than the second screw thread 51 of the lowering member 50, but the diameter of the adjusting screw coupled thereto is also corresponding thereto. It is more preferable that the lower end member 50 has a higher rotational ratio than the elevating member 60 when the adjusting screw is rotated by combining the screw threads 72a and 72b of the end, and the elevating member 60 is the adjusting screw. It is preferable to be formed integrally on the upper side of the support portion 71.

이에, 조절나사(70)의 회전시 승하강부재의 체결력에 따라 고정수단의 조임 및 해제를 빠르게 수행할 수 있다. Thus, according to the fastening force of the elevating member when the adjustment screw 70 rotates can be fastened and released fastening means.

이하, 본 발명의 사용상태를 설명하면 다음과 같다.Hereinafter, the use state of the present invention will be described.

도 4는 본 발명에 따른 파이프 부재용 길이조절장치의 사용상태단면도이다.Figure 4 is a cross-sectional view of the use state of the length adjusting device for pipe members according to the present invention.

먼저, 도 3을 참조하면, 가압부재(40)의 상하 양측에 각각 하강부재(50) 및 승강부재(60)를 구비한 다음, 하측으로부터 조절나사(70)를 관통하여 결합시킨다.First, referring to FIG. 3, a lowering member 50 and an elevating member 60 are provided on both upper and lower sides of the pressing member 40, and then the penetrating screw 70 is coupled from the lower side.

이때 하강부재(50)는 가이드 홈(52)을 가압부재(40)의 가이드 돌기(44)에 끼워 결합하며, 2단의 나사산으로 된 조절나사(70)의 피치에 따른 회전비를 고려해 하측의 승강부재(60)보다 하강부재(50)가 덜 체결된 상태에서 조절나사를 결합시킨다. 이에 조절나사(70)의 회동에 따른 빠른 체결력과 각각의 절개편을 동일하게 확개시킬 수 있게 된다. At this time, the lower member 50 is coupled to the guide groove (52) by inserting the guide groove (44) of the pressure member (40), the lower lifting in consideration of the rotational ratio according to the pitch of the adjustment screw 70 made of two-stage thread. The adjusting screw is coupled in a state where the lower member 50 is less engaged than the member 60. In this way, the fastening force and the respective cutting pieces according to the rotation of the adjustment screw 70 can be expanded in the same way.

상기 조절나사의 후단 지지부(71)에는 신장봉(20)을 결합한다.The extension rod 20 is coupled to the rear end support portion 71 of the adjusting screw.

이후, 고정수단(30)이 결합된 신장봉(20)은 고정봉(10)의 내부로 삽입하여 결합하게 되며, 이때 고정수단(30)의 외면에 형성된 방사형의 접촉날개(46)에 의해 가볍게 밀착되어 신장봉(20)을 회동시키더라도 가압부재(40)는 회동하지 않게 되며 나사조절에 따른 조임작동만 수행된다. Thereafter, the extension rod 20 to which the fixing means 30 is coupled is inserted into and coupled to the inside of the fixing rod 10, and at this time, lightly by the radial contact wings 46 formed on the outer surface of the fixing means 30. Even when the extension rod 20 is rotated in close contact, the pressing member 40 is not rotated and only the tightening operation according to the screw adjustment is performed.

이에 따라 신장봉(20)을 회동시키면 그 회동력이 하강부재 및 승강부재에 그대로 전달되어 조임 또는 해제 작동을 원활히 수행할 수 있게 된다. Accordingly, when the extension rod 20 is rotated, the rotational force is transmitted to the lowering member and the lifting member as it is, so that the tightening or releasing operation can be smoothly performed.

이때, 가압부재(40)의 양단 절개편은 고정봉(10)의 내면에 길이방향 소정구간 2곳에 각각 지지되므로 그 지지력은 아주 견고하며, 이 지지구간이 신장봉(20)과 고정봉(10)의 공차 유격을 보상해 주게 됨으로써 지지된 하측의 신장봉(20)을 고정봉(10)에서 좌우로 잡고 흔들어도 유동이 전혀 없게 된다. At this time, both ends of the pressing member 40 is supported on the inner surface of the fixed rod 10 in two predetermined sections in the longitudinal direction, so the supporting force is very solid, and this support section is the extension rod 20 and the fixed rod (10). By compensating for the clearance gap of), even if the lower extension rod 20 supported by the fixed rod 10 to the left and right to shake, there is no flow at all.
