Description

Technical Field

[0001] This invention relates to the field of sealing connection equipment technology, specifically to a leak-proof sealing connection device for hose connection. Background Technology

[0002] Hoses are essential components in modern industry. Flexible hoses and rigid fittings are used to transport fluids such as oil, water, air, and gases. Flexible hoses are often connected to other components such as end fittings, devices, or pipework. Flexible hoses are typically made of composites of different materials, including plastics, elastomers, rubber, wires, metal wires, or the like. With continuous technological development and societal progress, the applications of hoses are increasing. Hoses are used in many scenarios; their flexibility allows for greater flexibility, facilitating changes in pipe direction within confined spaces. However, hoses lack sufficient rigidity, and under external pressure, their cross-section is prone to deformation, leading to leaks.

[0003] Currently, when hoses are used to transport fluids, they are easily subjected to fluid impact and external forces, which can cause the connections to loosen and leak, resulting in poor sealing and significant safety hazards. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a leak-proof sealing connection device for hose connection, comprising: The hose body and bolts have a flared opening on the outer surface of the hose body, and a retaining ring is fixedly connected to the outer surface of the hose body near the flared opening, with the hose body passing through the center of the retaining ring. Also includes: The first connector and the second connector have the same structure but opposite orientation and are fixedly connected by bolts. The first connector has a conical shell that fits over the outer surface of the hose body. An annular groove is provided at the center of the outer surface of the conical shell. A first connecting ear plate is fixedly connected to the right edge of the outer surface of the conical shell. A circular hole is opened on the side surface of the first connecting ear plate. The first connector and the second connector are fixed by bolts. The outer surface of the horn opening is in contact with the inner surface of the conical shell. At the same time, the conical surface at the end of the cylinder is inside the horn opening. The horn opening is subjected to pressure. The horn opening is made of rubber, which is flexible and has a sealing effect. The horn opening is subjected to pressure from the top pressure ring. The outer surface of the horn opening is in contact with the inner surface of the annular groove. At this time, the outer surface of the horn opening forms a curved shape, thereby achieving a labyrinth seal and a good sealing effect. The leak-proof assembly includes a cylindrical body disposed inside a first connector and a second connector. Diverting fins are fixedly connected to the inner surface of the cylindrical body. Conical surfaces are provided at the left and right ends of the outer surface of the cylindrical body. A pressure ring is fixedly connected to the center of the outer surface of each conical surface, and a positioning module is fixedly connected to the center of the outer surface of the cylindrical body. By utilizing the conical surface at the end of the cylindrical body, which is located inside the conical shell, and under the pressure of the first and second connectors, the cylindrical body self-centers. At this time, the axes of the cylindrical body, the first connector, and the second connector are on the same horizontal line. The end of the cylindrical body presses against the inner surface of the flared opening, and the retaining ring causes the end of the flared opening to deform, thus achieving a preliminary seal. Furthermore, the conical surface tightly fits against the inner surface of the flared opening, achieving a second seal through the mutual cooperation between the conical surfaces. Through the interaction between the structures, multiple seals are achieved, making leakage less likely.

[0005] When the hose body transports fluid, the fluid enters the cylinder. At this time, the fluid is divided into multiple groups by the diversion fins, which weakens the impact of the overall flow and reduces the fluid impact force.

[0006] Preferably, the hose body is made of rubber, the retaining ring has a perforation at its center through which the hose body passes, and the retaining ring is made of metal.

[0007] Preferably, the side surface of the horn opening is fitted with the inner surface of the conical shell, the annular groove and the conical shell are integrally formed, and four first connecting ear plates are provided, with the four first connecting ear plates evenly distributed on the right edge of the outer surface of the conical shell.

[0008] Preferably, there are six diversion fins, which are evenly distributed on the inner surface of the cylinder, and two conical surfaces are provided, which are symmetrically arranged along the positioning module.

[0009] Preferably, the positioning module includes an annular base ring. The inner surface of the annular base ring is fixedly connected to the center of the outer circular surface of the cylinder. A semi-circular groove is formed on the edge of the outer surface of the annular base ring away from the cylinder. A limiting slot is formed on the side surface of the annular base ring near the semi-circular groove. The annular base ring can be moved through the semi-circular groove, so that the cylinder is subjected to a moving force, causing the cylinder and the annular base ring to rotate together for adjustment. The position of the limiting slot is adjusted to the corresponding position of the spherical clamping block, which helps the subsequent structures to cooperate with each other and promotes the subsequent achievement of the limiting effect.

[0010] Preferably, four semicircular grooves are provided, and the four semicircular grooves are evenly distributed on the outer surface edge of the annular base ring, and the limiting grooves are evenly distributed on the side surface of the annular base ring.

[0011] Preferably, an auxiliary component is provided between the first connector and the second connector, near the positioning module. The auxiliary component includes a connecting ring, which is sleeved on the outer surface of the cylinder. A second connecting lug is fixedly connected to the outer edge of the connecting ring, and the position of the second connecting lug corresponds to the position of the first connecting lug. A through hole is opened on the side surface of the second connecting lug. A washer is fixedly connected to the side surface of the connecting ring. A sealing ring is fixedly connected to the side of the connecting ring away from the washer. A support spring is fixedly connected to the inner surface of the connecting ring. A clamping module is provided on the inner surface of the connecting ring near the support spring. When the bolts are fixed, the two symmetrical connecting rings move towards each other, and the support spring is compressed. By compressing and deforming the sealing ring and the washer, the connection between the first connector and the second connector can be sealed. When it is necessary to disassemble the first connector and the second connector, the bolts are loosened. At this time, under the elastic force of the support spring, the two symmetrical connecting rings together apply an outward pushing force to the first connector and the second connector, which helps to disassemble the whole device.

[0012] Preferably, both the washer and the sealing ring are made of rubber, the outer surface of the support spring is curved, and there are two connecting rings, which are symmetrically arranged along the width direction of the support spring.

[0013] Preferably, the clamping module includes a rectangular base block. The bottom of the outer surface of the rectangular base block is fixedly connected to the inner surface of the connecting ring. An elastic strip is fixedly connected to the outer surface of the rectangular base block on the side away from the inner surface of the connecting ring. A spherical clamping block is fixedly connected to the end of the elastic strip away from the rectangular base block. The elastic strip applies an elastic pressing force to the spherical clamping block. At this time, the annular base ring is limited, and the position of the cylinder is fixed, making it less susceptible to external forces and vibrations, and reducing shaking.

[0014] Preferably, the rectangular base blocks are evenly distributed on the inner surface of the connecting ring, and the elastic strip is set to a right angle.

[0015] This invention provides a leak-proof sealing connection device for hose connections. It has the following advantages: 1. The leak-proof sealing connection device for the hose connection uses bolts to fix the first connector and the second connector, and uses the outer surface of the horn opening to fit against the inner surface of the conical shell. At the same time, the conical surface at the end of the cylinder is inside the horn opening, and the horn opening is subjected to top pressure. The horn opening is made of rubber, which is flexible and has a sealing effect. The horn opening is subjected to top pressure from the top pressure ring, and the outer surface of the horn opening fits against the inner surface of the annular groove. At this time, the outer surface of the horn opening forms a curved shape, thereby achieving a labyrinth seal, resulting in a good sealing effect.

[0016] II. The leak-proof sealing connection device for this hose connection utilizes bolts for fixing. At this time, the conical surface at the end of the cylinder is inside the conical shell. Under the pressure of the first connector and the second connector, the axes of the cylinder, the first connector, and the second connector are on the same horizontal line. The end of the cylinder presses against the inner surface of the flared opening, causing the end of the flared opening to deform, thereby achieving a preliminary seal. Furthermore, the conical surface and the inner surface of the flared opening are tightly fitted together. Through the mutual cooperation between the cones, a second seal is achieved. Through the interaction between the structures, multiple seals are achieved, making leakage less likely.

[0017] 3. The leak-proof sealing connection device for the hose connection: when the hose body transports fluid, the fluid will enter the cylinder. At this time, multiple groups of fluid will be formed by the division of the flow divider fins, thereby weakening the impact of the overall flow and reducing the fluid impact force.

[0018] IV. The leak-proof sealing connection device for the hose connection allows the annular base ring to be moved through the semi-circular groove when the leak-proof component is positioned between the first connector and the second connector. This causes the cylinder to be subjected to a moving force, which in turn causes the cylinder and the annular base ring to rotate together for adjustment. The position of the limiting slot is adjusted to the corresponding position of the spherical clamping block, which helps the subsequent structures to cooperate with each other and promotes the subsequent achievement of the limiting effect.

[0019] 5. The leak-proof sealing connection device for the hose connection, under the fixation of the bolts, the two symmetrical connecting rings on both sides move towards each other, and the supporting spring is compressed. By using the compression deformation of the sealing ring and the gasket, the connection between the first connector and the second connector can be sealed. When it is necessary to disassemble the first connector and the second connector, the bolts are loosened. At this time, under the elastic force of the supporting spring, the two symmetrical connecting rings on both sides together apply an outward pushing force to the first connector and the second connector, which helps to disassemble the whole device.

[0020] VI. The leak-proof sealing connection device for the hose connection, when the two symmetrical connecting rings on both sides move towards each other, causes the spherical clamping block to be driven to move closer to the limiting groove until the spherical clamping block is embedded in the limiting groove. At this time, the elastic strip applies elastic pressing force to the spherical clamping block, and the annular base ring is limited, so that the position of the cylinder is fixed and not easily affected by external forces and vibrations, reducing the occurrence of shaking.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0024] First embodiment, such as Figures 1-3 As shown, the present invention provides a technical solution: a leak-proof sealing connection device for hose connection, comprising: The hose body 1 and the bolt 2 are provided with a flared opening 3 on the outer surface of the hose body 1 to facilitate the interoperability of the structures. A retaining ring 4 is fixedly connected to the outer surface of the hose body 1 near the flared opening 3, and the hose body 1 passes through the center of the retaining ring 4. Also includes: The first connector 5 and the second connector 6 have the same structure but opposite orientation, and are fixedly connected by bolts 2. The first connector 5 has a conical shell 51 that fits onto the outer surface of the hose body 1. An annular groove 52 is provided at the center of the outer surface of the conical shell 51. A first connecting ear plate 53 is fixedly connected to the right edge of the outer surface of the conical shell 51, and a circular hole 54 is opened on the side surface of the first connecting ear plate 53. The conical shell 51 is fitted onto the outer surface of the hose body 1, with the conical shell 51 close to the horn opening 3, and the second connector 6 is then... The first connector 5 and the second connector 6 are fixed by bolts 2, and the outer surface of the horn opening 3 is attached to the inner surface of the conical shell 51. At the same time, with the first connector 5 and the second connector 6 connected, the conical surface 73 at the end of the cylinder 71 is inside the horn opening 3, and the horn opening 3 is subjected to pressure. The horn opening 3 is made of rubber, which is flexible and has a sealing effect. The horn opening 3 is subjected to pressure from the top pressure ring 74, and the outer surface of the horn opening 3 is attached to the inner surface of the annular groove 52. At this time, the outer surface of the horn opening 3 forms a curved shape, thereby achieving a labyrinth seal and making the sealing effect good. The hose body 1 is made of rubber. The retaining ring 4 has a hole in the center through which the hose body 1 passes. The retaining ring 4 is made of metal, which has high strength and is convenient for supporting the end of the horn opening 3.

[0025] The side surface of the horn opening 3 fits against the inner surface of the conical shell 51, which facilitates the compression of the horn opening 3. The annular groove 52 and the conical shell 51 are integrated. Four first connecting ear plates 53 are provided, and the four first connecting ear plates 53 are evenly distributed on the right edge of the outer surface of the conical shell 51.

[0026] Second embodiment, such as Figures 1-6 As shown, based on the first embodiment: The leak-proof component 7 has a cylindrical body 71 disposed inside the first connector 5 and the second connector 6. Diverting fins 72 are fixedly connected to the inner surface of the cylindrical body 71. A tapered surface 73 is provided at both the left and right ends of the outer surface of the cylindrical body 71. A top pressure ring 74 is fixedly connected to the center of the outer surface of the tapered surface 73, and a positioning module 75 is fixedly connected to the center of the outer surface of the cylindrical body 71. The leak-proof component 7 is entirely located inside the first connector 5 and the second connector 6, and is fixed by bolts 2. Combined with the tapered shape of the tapered housing 51, the tapered surface 73 at the end of the cylindrical body 71... Inside the conical shell 51, and under the pressure of the first connector 5 and the second connector 6, the cylinder 71 self-centers. At this time, the axes of the cylinder 71, the first connector 5 and the second connector 6 are on the same horizontal line, and the end of the cylinder 71 presses against the end of the inner surface of the horn opening 3. Through the blocking of the retaining ring 4, the end of the horn opening 3 is deformed, thereby achieving a preliminary seal. The conical surface 73 fits tightly with the inner surface of the horn opening 3. By utilizing the mutual cooperation between the cones, a seal is achieved again. Through the interaction between the structures, multiple seals are achieved, making leakage less likely.

[0027] When the hose body 1 conveys fluid, the fluid enters the cylinder 71. At this time, the fluid is divided into multiple groups by the diversion fins 72, which weakens the impact of the overall flow and reduces the fluid impact force.

[0028] There are six diversion fins 72, which are evenly distributed on the inner surface of the cylinder 71 to facilitate the uniform division of the fluid transported in the cylinder 71. There are two conical surfaces 73, which are symmetrically arranged along the positioning module 75 to facilitate the sealing of both ends.

[0029] The positioning module 75 includes an annular base ring 751. The inner surface of the annular base ring 751 is fixedly connected to the center of the outer circular surface of the cylinder 71. A semi-circular groove 752 is provided on the edge of the outer surface of the annular base ring 751 away from the cylinder 71. A limiting groove 753 is provided on the side surface of the annular base ring 751 near the semi-circular groove 752. When the anti-leakage component 7 is placed between the first connector 5 and the second connector 6, and the annular base ring 751 is fixed on the outer circular surface of the cylinder 71, the annular base ring 751 can be moved through the semi-circular groove 752, so that the cylinder 71 is subjected to a moving force, causing the cylinder 71 and the annular base ring 751 to rotate together for adjustment. The position of the limiting groove 753 is adjusted to the corresponding position of the spherical clamping block 873, which helps the subsequent structures to cooperate with each other and promotes the subsequent achievement of the limiting effect.

[0030] There are four semicircular grooves 752, and the four semicircular grooves 752 are evenly distributed on the outer surface edge of the annular base ring 751. The limiting grooves 753 are evenly distributed on the side surface of the annular base ring 751, which facilitates the adjustment of the annular base ring 751.

[0031] The third embodiment, such as Figures 1-3 and Figures 7-8 As shown, based on the first embodiment: An auxiliary component 8 is provided between the first connector 5 and the second connector 6, near the positioning module 75. The auxiliary component 8 includes a connecting ring 81, which is sleeved on the outer surface of the cylinder 71. A second connecting ear plate 82 is fixedly connected to the outer edge of the connecting ring 81. The position of the second connecting ear plate 82 corresponds to the position of the first connecting ear plate 53. A through hole 83 is opened on the side surface of the second connecting ear plate 82. A washer 84 is fixedly connected to the side surface of the connecting ring 81. A sealing ring 85 is fixedly connected to the side of the connecting ring 81 away from the washer 84. A support spring 86 is fixedly connected to the inner surface of the connecting ring 81. A clamping module 87 is provided on the inner surface of the connecting ring 81 near the support spring 86. A bolt 2 passes through the through hole 83 and is fixed by the bolt 2. At this time, the two symmetrical connecting rings 81 move towards each other and the support spring 86 is compressed. The sealing ring 85 and the washer 84 are deformed by compression, which can seal the connection between the first connector 5 and the second connector 6.

[0032] When it is necessary to disassemble the first connector 5 and the second connector 6, the bolt 2 is loosened. At this time, under the elastic force of the supporting spring 86, the two symmetrical connecting rings 81 on both sides exert an outward pushing force on the first connector 5 and the second connector 6, which helps to disassemble the whole device.

[0033] Both the washer 84 and the sealing ring 85 are made of rubber, which is easy to deform under pressure, thus helping to seal. The outer surface of the support spring 86 is curved. There are two connecting rings 81, and the two connecting rings 81 are symmetrically arranged along the width direction of the support spring 86.

[0034] The clamping module 87 includes a rectangular base block 871. The bottom of the outer surface of the rectangular base block 871 is fixedly connected to the inner surface of the connecting ring 81. An elastic strip 872 is fixedly connected to the outer surface of the rectangular base block 871 away from the inner surface of the connecting ring 81. A spherical clamping block 873 is fixedly connected to the end of the elastic strip 872 away from the rectangular base block 871. When the two symmetrical connecting rings 81 move towards each other, the rectangular base block 871 drives the elastic strip 872 to move, which in turn drives the spherical clamping block 873 to move closer to the limiting groove 753 until the spherical clamping block 873 is embedded in the limiting groove 753. At this time, the elastic strip 872 applies an elastic pressing force to the spherical clamping block 873. The annular base ring 751 is limited, and the position of the cylinder 71 is fixed, making it less susceptible to external forces and vibrations, reducing shaking, and making full use of the interaction between the structures to connect the structures together.

[0035] Rectangular base blocks 871 are evenly distributed on the inner surface of the connecting ring 81. The elastic strip 872 is set in a right angle shape, which facilitates the support of the spherical clamping block 873 and helps to deform under force.

[0036] In use, first install the first connector 5 and the second connector 6 onto the end of the hose body 1, and then install the leak-proof component 7 into the inside of the connecting ring 81. Next, place the leak-proof component 7 and the auxiliary component 8 between the first connector 5 and the second connector 6. The annular base ring 751 can be moved through the semi-circular groove 752, causing the cylinder 71 to be rotated and adjusted along with the annular base ring 751. Adjust the position of the limiting slot 753 to the corresponding position of the spherical clamping block 873. Then, pass the bolt 2 through the circular hole 54 and the through hole 83 to fix the first connector 5 and the second connector 6. At this point, the two symmetrical connecting rings 81 move towards each other, and the supporting spring 86 is compressed. The sealing ring 85 and the washer 84 are deformed by compression, sealing the connection between the first connector 5 and the second connector 6. Simultaneously, the first... With the connector 5 and the second connector 6 connected in a cooperative manner, the tapered surface 73 at the end of the cylinder 71 is inside the horn opening 3, and the horn opening 3 is subjected to pressure, which causes the horn opening 3 to be pressed by the pressure ring 74. The outer surface of the horn opening 3 is in contact with the inner surface of the annular groove 52, and the outer surface of the horn opening 3 forms a curved shape, thereby achieving a labyrinth seal. The entire anti-leakage component 7 is located inside the first connector 5 and the second connector 6 and is fixed by the bolt 2. At this time, the tapered surface 73 at the end of the cylinder 71 is inside the tapered shell 51, and the end of the cylinder 71 presses against the end of the inner surface of the horn opening 3. Through the blocking of the retaining ring 4, the end of the horn opening 3 is deformed, thereby achieving a preliminary seal. The tapered surface 73 is tightly in contact with the inner surface of the horn opening 3. By utilizing the mutual cooperation between the tapered surfaces, a seal is achieved again, making it difficult for leakage to occur. After the entire device is installed, when the hose body 1 transports fluid, the fluid will enter the cylinder 71. At this time, multiple groups of fluid will be formed under the division of the diverting fins 72, thereby weakening the impact of the overall flow. When it is necessary to disassemble the entire device, the bolts 2 are loosened and removed. At this time, under the elastic force of the supporting spring 86, the two symmetrical connecting rings 81 on both sides will exert an outward pushing force on the first connector 5 and the second connector 6, which will help to disassemble the entire device.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
