본 발명은 굴삭기 또는 불도저 등의 산업기계에 사용되는 패킹 조립체에 관 한 것으로, 더욱 상세하게는 절단 링 형태로 된 패킹의 각 단부에 연결부를 형성하되, 그 일측 연결부에는 체결공을 형성하고 타측 연결부에는 걸림돌조가 연속 형성된 체결밴드를 일체로 돌출 형성하여 별도의 결속수단 없이도 상기 체결밴드에 의해 견고한 체결이 이루어짐은 물론 진동이나 충격에 의한 느슨함이 예방되고, 이완상태에서는 용이하게 긴장력을 증대시킬 수 있는 것이며, 저면의 수밀돌조는 그 수밀성을 향상시키는 특징의 산업기계용 패킹 조립체에 대한 것이다.The present invention relates to a packing assembly used for an industrial machine such as an excavator or a bulldozer, and more particularly, to form a connection portion at each end of the packing in the form of a cutting ring, the connection portion on one side to form a fastening hole and the other connection portion In the protrudingly formed fastening band integrally formed with a fastening protrusion is securely fastened by the fastening band without a separate fastening means, as well as looseness due to vibration or shock is prevented, can easily increase the tension in the relaxed state. The watertight protrusions on the bottom face the packing assembly for industrial machines characterized by improving the watertightness.

일반적으로 굴삭기 또는 불도저 등의 버킷 힌지부분에는 상기한 버킷의 원활한 작동을 유도하게 하는 그리스 등의 윤활제가 투입되는데, 이와 같은 회전축은 작업중 흙이나 모래 등에 의해 노출되어 이들 간섭물에 의해 상기한 윤활제가 소실되는 문제점이 발생하므로 상기와 같은 회전축 부분에는 개방형 패킹 조립체를 결합함으로써, 이에 의해 내부 윤활제의 소실을 방지하면서도 그 힌지부 내측으로 이물질이 유입되는 것을 방지하고 있는 것이다.Generally, a lubricant such as grease is introduced into the bucket hinge portion of an excavator or a bulldozer to induce smooth operation of the bucket. Such a rotating shaft is exposed to soil or sand during operation, and the lubricant is prevented by these interferences. Since there is a problem of disappearance by combining the open packing assembly to the rotary shaft portion as described above, thereby preventing the loss of the internal lubricant while preventing foreign matter from flowing into the hinge portion.

이와 같은 패킹 조립체는 도 1의 도시와 같이 절단된 링 형태의 고무재로 성형된 패킹몸체(100)로 이루어져 있고, 그 절단 양단에는 각각 보다 확장된 크기의 연결부(101)(101')가 형성되어 있으며, 상기한 연결부(101)(101')는 횡상의 체결공(102)(102')이 관통 형성됨에 따라 별도의 체결볼트(103) 및 고정너트(104)(104')를 이용하여 이들 분리된 연결부(101)(101')를 견고하게 체결할 수 있는 구조를 갖고 있다.Such a packing assembly is composed of a packing body 100 formed of a ring-shaped rubber material as shown in Figure 1, the ends of the cutting are formed with connecting portions 101, 101 'of a more extended size, respectively. As the connection portion 101, 101 'is formed through the horizontal fastening holes 102, 102' through the use of separate fastening bolt 103 and fixing nuts 104, 104 '. It has a structure which can firmly fasten these separated connection parts 101 and 101 '.

따라서, 분리 가능한 상태의 패킹몸체(100)를 이용하여 이를 대상물에 결합 한 상태에서 상기한 체결볼트(103)와 이중의 고정너트(104)(104')를 이용하여 상기한 대상물에 그 패킹 조립체를 견고하게 수밀 장착하면 되는 것이다.Accordingly, the packing assembly 100 is attached to the object using the fastening bolt 103 and the double fixing nut 104 and 104 'in the state in which it is coupled to the object using the packing body 100 in a detachable state. It is to be firmly mounted watertight.

그러나, 상기한 바와 같은 패킹 조립체는 진동이나 빈번한 충격이 발생되는 산업기계에 주로 사용되는 것이므로, 상기와 같이 반복적이거나 간헐적인 진동 및 충격이 가해지는 경우에는 그 고정너트의 풀림 현상이 발생하게 되므로, 상기 고정너트가 풀리게 되면 분할된 양측의 연결부 사이가 벌어지며 이를 통해 내부의 윤활제가 흘러나오거나, 외부로부터 각종 이물질 등이 유입되는 문제가 발생하게 된다.However, the packing assembly as described above is mainly used in industrial machinery that vibration or frequent shocks occur, and thus, when repetitive or intermittent vibrations and shocks are applied as described above, loosening of the fixing nut occurs. When the fixing nut is released, there is a gap between the connection parts of the divided both sides, through which the lubricant flows out, or various foreign matters are introduced from the outside.

특히, 고무재로 된 패킹몸체와 금속재의 체결볼트 사이의 접촉부에는 그 패킹몸체에 상당한 부하가 작용하므로 상대적으로 내구성이 떨어지는 고무재의 패킹몸체가 쉽게 끊어지는 문제점을 갖고 있는 것이며,In particular, the contact portion between the packing body of the rubber material and the fastening bolt of the metal material has a problem that the packing body of the rubber material of relatively inferior durability is easily broken because a considerable load acts on the packing body.

상기와 같은 종래의 패킹 조립체는 금속재의 체결볼트와 고정너트를 이용하므로 이들을 이용하여 패킹을 설치하거나 분리 또는 교체하는 경우에는 상당한 번거로움이 뒤따르는 것이며, 이들이 이완되거나 느슨해지는 경우에도 스패너 등의 공구를 이용하여 이들을 견고하게 고정시켜 주어야 하므로 공구가 미처 마련되지 않은 상태에서는 신속한 초기 대응이 이루어지지 않아 매우 비효율적인 것이다.The conventional packing assembly as described above uses fastening bolts and fixing nuts of metal material, and thus, when installing, removing or replacing the packings using them, a considerable amount of cumbersome work is performed, and even when they are loosened or loosened, tools such as spanners are used. They must be firmly fixed using them, so that the initial response cannot be achieved without the tools already in place, which is very inefficient.

본 발명은 전기한 바와 같은 문제점을 개선하고자 안출된 것으로서, 절단링 형태로 된 패킹의 양단부에 각각 확대연결부를 형성하되, 일측 확대연결부에는 횡 상의 체결공을 형성하고, 타측 확대연결부에는 걸림돌조가 반복 형성된 체결밴드를 일체로 성형하여, 그 체결밴드가 체결공으로 삽입 결합됨에 따라 이들 연결부가 상호 체결되게 함으로서 별도의 체결수단 없이도 분리형 패킹의 견고한 결속이 가능한 것이며, 부품의 망실 위험이 없어 취급 및 관리가 용이한 것이며,The present invention has been made in order to improve the problems as described above, each of which is formed in each of the expansion connecting portion on the end of the packing in the form of a cutting ring, one side expansion connecting portion to form a horizontal fastening hole, the other expansion connecting portion is repeated hook As the formed fastening band is integrally formed and the fastening band is inserted into the fastening hole, these connecting parts are fastened to each other so that a solid packing of the separate packing is possible without a separate fastening means. Easy

진동 및 충격으로부터 보다 안정된 결속력을 유지하므로 내부 윤활제의 누출이나 외부 이물질의 유입이 방지됨은 물론 이완 상태에서는 용이하게 긴장력을 증대시킬 수 있는 것이며, 확대연결부의 저면 양측에 형성된 곡선상의 수밀돌조에 의해서는 대상물과의 접지면적을 확대시켜 수밀성을 크게 향상시킨 특징을 갖는 산업기계용 패킹 조립체를 제공함에 본 발명의 목적이 있는 것이다.By maintaining a more stable binding force from vibration and shock, it is possible to prevent leakage of internal lubricants and inflow of external foreign matters, and to increase tension in a relaxed state easily. The curved watertight protrusions formed on both sides of the bottom of the enlarged connection part SUMMARY OF THE INVENTION An object of the present invention is to provide a packing assembly for an industrial machine having a feature of greatly improving watertightness by enlarging the ground area with an object.

이하, 본 발명의 바람직한 실시예를 설명한다.Hereinafter, preferred embodiments of the present invention will be described.

도 2는 본 발명에 따른 패킹 조립체의 전개 사시도이고, 도 3은 본 발명에 따른 패킹 조립체의 체결 사시도이며, 도 4는 본 발명에 따른 패킹 조립체의 체결 상태의 단면도이다.2 is an exploded perspective view of a packing assembly according to the present invention, FIG. 3 is a fastening perspective view of the packing assembly according to the present invention, and FIG. 4 is a cross-sectional view of a fastening state of the packing assembly according to the present invention.

절단 링 형태로 된 패킹몸체(1)의 절단 양 단부에 확대연결부(2)(2')를 각각 형성하되,Expanding portions (2) (2 ') are formed on both ends of the cutting body of the packing body (1) in the form of a cutting ring,

일측 확대연결부(2)에는 횡상의 체결공(3)을 형성하고, 타측 확대연결부(2')에는 걸림돌조(4)(4')가 반복 성형된 봉 형태의 체결밴드(5)를 일체로 성형하여 그 체결밴드(5)가 상기 체결공(3)으로 삽입되어 상기한 걸림돌조(4)(4')에 의해 서로 결속되게 구성하고,On one side of the connecting portion (2) is formed a lateral fastening hole (3), and on the other side of the connecting portion (2 ') of the rod-like fastening band (5) in which the locking projection (4) (4') is repeatedly molded By molding, the fastening bands 5 are inserted into the fastening holes 3 so as to be bound to each other by the locking projections 4 and 4 '.

상기 확대연결부(2)(2')의 저면 양측으로는 곡선 형태의 수밀돌조(6)(6')를 돌출 형성하여 구성한 것이다.On both sides of the bottom surface of the enlarged connecting portion (2) (2 ') is formed by projecting the watertight protrusion (6) (6') of the curved form.

이상과 같은 구성에 의한 본 발명 산업기계용 패킹 조립체의 작용을 첨부도면에 의해 보다 상세히 설명하면 다음과 같다.Referring to the action of the packing assembly for an industrial machine of the present invention according to the configuration as described above in more detail as follows.

도시와 같이 산업기계용 패킹 조립체는 일반적인 밀폐 링 형태가 아닌 절단 단부를 갖는 개방형 링으로 이루어진 것으로서, 절단 단부를 갖는 패킹몸체(1)에는 그 절단 단부에 보다 확대 형성된 확대연결부(2)(2')가 각각 형성되어 있는 것이다.As shown in the figure, the packing assembly for an industrial machine is composed of an open ring having a cutting end rather than a general sealing ring. The packing body 1 having the cutting end has an enlarged connection portion 2 (2 ') formed at the cutting end. ) Are formed respectively.

이들 확대연결부(2)(2')는 상기한 패킹몸체(1)의 절단 단부 상측에 보강 성형되는 것으로서, 절단된 패킹몸체(1)를 연결하거나 분리하는 결속구의 역할을 하게 된다.These enlarged connecting portions (2) (2 ') is to be reinforced to the upper end of the cutting end of the packing body 1, and serves as a binding hole for connecting or separating the cut packing body (1).

이와 같은 확대연결부(2)(2')를 통해 종래에는 별도의 체결볼트나 고정너트 등을 이용하여 분리된 확대연결부를 결속하거나 분리되게 하였으나, 주지한 바와 같이 종래의 패킹 조립체의 경우에는 상당한 문제점을 갖고 있는 것으로서, 본 발명에 의해서는 종래의 패킹 조립체가 갖는 제반의 문제점을 극복한 것이다.Through the expansion connection (2) (2 ') as described above it is conventional to use a separate fastening bolt or a fixing nut to bind or separate the separated expansion connection, but as is well known in the case of the conventional packing assembly is a significant problem The present invention overcomes all the problems of conventional packing assemblies.

즉, 상기한 확대연결부(2)(2')에 있어 일측의 확대연결부(2)에는 횡상의 체결공(3)을 형성하고 타측의 확대연결부(2')에는 횡상의 체결밴드(5)를 상기 체결공(3)의 내경과 알맞도록 돌출 형성하되, 그 체결밴드(5)에는 쐐기형의 걸림돌 조(4)(4')를 일체로 반복 형성한 것이다.That is, in the enlarged connecting portion (2) (2 ') is formed a horizontal fastening hole (3) in the enlarged connecting portion (2) on one side, and a horizontal fastening band (5) in the enlarged connecting portion (2') on the other side Protrudingly formed to fit the inner diameter of the fastening hole (3), the fastening band (5) is formed integrally and repeatedly formed wedge-shaped locking jaw (4) (4 ').

따라서, 상기한 확대연결부(2)(2')가 분리된 상태에서 그 패킹몸체(1)를 대상물에 적용한 후, 상기한 체결밴드(5)의 단부를 체결공(3)으로 강제 삽입하게 되면 이를 통해 타측으로 체결밴드(5)의 단부가 노출되므로 노출된 체결밴드(5)를 잡아 당겨 이격된 확대연결부(2)(2')의 단부가 서로 긴밀하게 접지되게 하는 것이며, 상기한 체결밴드(5)를 지속적으로 잡아당기게 되면 고무재로 된 체결밴드(5)의 신축력에 의해 해당 위치의 걸림돌조(4)(4')가 체결공(3)을 통해 외부로 노출되므로 그 걸림돌조(4)(4')의 걸림력에 의해 이들 확대연결부(2)(2')는 탄력적으로 견고한 체결상태가 유지되는 것이다.Therefore, after the packing body 1 is applied to the object in the state in which the enlarged connecting portion 2, 2 'is separated, the end of the fastening band 5 is forcibly inserted into the fastening hole 3. As a result, the ends of the fastening bands 5 are exposed to the other side, so that the ends of the enlarged connecting parts 2 and 2 'spaced apart by pulling the exposed fastening bands 5 are closely grounded to each other. (5) is continuously pulled by the elastic force of the fastening band (5) made of rubber material because the locking protrusion (4) (4 ') of the corresponding position is exposed to the outside through the fastening hole (3) 4) By the locking force of (4 ') these expansion connection (2) (2') is to maintain the elastically secure fastening state.

이와 같은 체결 상태는 상기한 체결밴드(5)가 지속적으로 신축성을 갖고 있으므로 충격 및 진동으로부터 매우 적합한 체결 안정성을 유지하게 되는 것이며, 탄력적인 상태로 결속되어 있으므로 분리된 확대연결부(2)(2')는 서로 단부를 향하여 지속적으로 미는 힘이 작용하게 되므로 보다 긴밀한 상태의 체결이 유지되는 것이다.In this fastening state, the fastening band 5 is continuously stretched to maintain a very suitable fastening stability from shock and vibration, and is connected in an elastic state, so that the enlarged connection part 2 (2 ') is separated. ) Is a force that is continuously pushed toward the end of each other to maintain a tighter tightening state.

특히, 고무재 특유의 탄성이 저하되어 그 패킹몸체(1)의 결속력이 완화된 경우에는 상기와 같이 결속 상태에서 일측으로 노출된 체결밴드(5)를 잡아 당겨 그 체결공(3) 내의 걸림돌조(4)(4')가 외부로 한 단계 더 돌출되게 하면 그 체결부의 이완된 상태로부터 보다 증대된 긴장력을 제공하게 되는 것으로서, 도 5의 도시와 같이 굴삭기의 버킷 힌지부에 적용되는 경우 그 힌지부의 원활한 작동을 유도하는 그리스 등의 윤활제가 노출되는 것을 방지하면서도 작업시 이물질이 그 회전축이나 윤활부 내측으로 유입되는 것을 방지하는 역할을 하게 되는 것이다.In particular, when the elasticity peculiar to the rubber material is lowered and the binding force of the packing body 1 is relaxed, as shown above, the locking band 5 in the coupling hole 3 is pulled by pulling the fastening band 5 exposed to one side in the binding state. (4) If the 4 'is protruded to the outside one step to provide an increased tension from the relaxed state of the fastening portion, the hinge when applied to the bucket hinge portion of the excavator as shown in FIG. While preventing grease such as grease, which leads to smooth operation of the part, it prevents foreign substances from entering the rotating shaft or the lubrication part during operation.

따라서, 별도로 분리되는 부품이 전혀 없는 상태에서도 그 패킹 조립체의 사용이 가능하므로 부품의 망실 위험이 전혀 없어 취급이 매우 용이한 것이며, 단일 부품만으로도 제품을 완성할 수 있어 생산성 향상은 물론 생산 원가 절감에도 이바지할 수 있는 것이다.Therefore, the packing assembly can be used even when there are no separate parts, so there is no risk of loss of parts, and the handling is very easy. You can contribute.

특히, 본 발명 패킹 조립체는 확대연결부(2)(2')의 저면 양측에 곡선 형태의 수밀돌조(6)(6')를 돌출 형성함에 따라 그 수밀돌조(6)(6')에 의해 대상물과의 기밀 및 수밀성을 더욱 향상시킬 수 있는 것인데, 일반적인 개방형 패킹의 경우 수밀 취약부는 절단 단부일 것이므로 그 절단 단부에 해당하는 확대연결부(2)(2')의 저면에 그 대상물과 접촉하는 수밀돌조(6)(6')를 양측으로 돌출 성형함에 따라 그에 의해 상기 대상물과의 수밀 및 기밀성이 가일층 향상되게 한 것이다.In particular, the packing assembly of the present invention is formed in the watertight protrusion (6) (6 ') by protruding the watertight protrusion (6) (6') of the curved shape on both sides of the bottom of the enlarged connecting portion (2) (2 '). It is possible to further improve airtightness and watertightness with the object. In the case of a general open packing, the watertight weakness portion will be the cut end, so that the bottom of the enlarged connection part 2 (2 ') corresponding to the cut end is in contact with the object As the watertight protrusions 6 and 6 'are protruded to both sides, the watertightness and airtightness with the said object are further improved.

이상과 같은 본 발명 산업기계용 패킹 조립체는, 일체의 고무재로 된 밴드에 의해 그 연결부가 상호 체결되게 함으로서 별도의 체결수단 없이도 분리형 패킹의 견고한 결속이 가능한 것이며, 부품의 망실 위험이 없어 취급 및 관리가 용이한 것이며, 진동 및 충격으로부터 보다 안정된 결속력을 유지하므로 내부 윤활제의 누출이나 외부 이물질의 유입이 방지됨은 물론 이완 상태에서는 용이하게 긴장력을 증대시킬 수 있는 것이며, 수밀돌조에 의해서는 대상물과의 접지면적을 확대시켜 수밀성을 크게 향상시키는 효과가 있는 것이다.The packing assembly for industrial machines of the present invention as described above allows the connection parts to be fastened to each other by an integral band of rubber material, so that the solid packing of the separate packing is possible without a separate fastening means, and there is no risk of loss of parts. It is easy to manage and maintains more stable binding force from vibration and shock, which prevents leakage of internal lubricants and inflow of foreign substances, and can easily increase tension in the relaxed state. Increasing the ground area will greatly improve the watertightness.
