Description

Technical Field

[0001] This utility model relates to the field of hose connector technology, specifically a hose connector with high sealing performance. Background Technology

[0002] In many fields of industrial production, fluid transportation, and daily life, hose fittings play a crucial role in the performance and applicability of connecting hoses to other components.

[0003] Currently, most hose fittings on the market are designed and manufactured for hoses of specific diameters. This means that a single type of hose fitting can generally only be used with hoses of one diameter. For example, in automobile manufacturing, hose fittings used for coolant delivery must be prepared in various sizes when connecting coolant hoses of different diameters. This not only increases the inventory management cost of parts but can also cause installation difficulties or poor sealing due to incorrect selection of the wrong size during installation.

[0004] Even those hose fittings that claim to be compatible with multiple pipe diameters often fall short of expectations in actual use. These so-called "multi-functional" fittings frequently employ complex adjustment structures, such as multi-layered nested pipe diameter adapters. During installation, operators need to perform tedious adjustments, such as rotating multiple threaded components to change the internal pipe diameter adaptation dimensions. This not only consumes a significant amount of time and effort but also, due to the complexity of the operation, is prone to human error during installation, leading to compromised sealing performance and potential safety hazards such as fluid leaks. Furthermore, the complex structure significantly increases the manufacturing cost of the fitting, and during long-term use, frequent adjustments accelerate wear, further reducing its sealing performance and service life.

[0005] Therefore, we propose a high-sealing-performance hose connector to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the shortcomings of the prior art, this utility model provides a high-sealing-performance hose connector to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a high-sealing-performance hose connector, comprising a first pipe, a second pipe disposed on one side of the first pipe, a tail piece sleeved on the second pipe, and a first through hole formed on the tail piece.

[0010] Preferably, a limiting piece is fixedly connected at equal intervals on the outer ring surface of the rear tail piece, and the limiting piece is provided with a hexagonal groove.

[0011] Preferably, a front cover is fitted onto the rear tail piece, and an auxiliary piece is fixedly connected to the front end of the front cover. Guide grooves are provided on the auxiliary piece at equal intervals.

[0012] Preferably, the auxiliary piece has a second through hole, and a retaining strip is fixedly connected to the inner ring wall of the front cover.

[0013] Preferably, a sliding column is slidably connected in the guide groove, a fastening piece is fixedly connected in the middle of the sliding column, and the bottom surface of the sliding column is slidably connected in the rear tail piece.

[0014] Preferably, the outer side of the fastening piece is provided with a recessed groove, the first pipe is provided with a plug ring, and the plug ring is provided with a third through hole.

[0015] Preferably, a magnetic ring is fitted and fixedly connected to the rear tail piece.

[0016] Preferably, the front cover is made of magnetic metal, which can be iron.

[0017] Preferably, the retaining strip is used in conjunction with the limiting plate, mainly to limit the rotation direction of the front cover and prevent it from rotating in the opposite direction, which would affect the tightness and sealing of the pipes.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a high-sealing-performance hose connector, which has the following beneficial effects:

[0020] 1. Through the design of the overall device, this utility model can flexibly adapt to multiple pipe diameters compared to traditional hose connectors that can only adapt to a single pipe diameter. In the coolant delivery pipeline system of automobile manufacturing and other fields, there is no need to store a large number of connectors of different specifications, which greatly reduces the inventory management cost of parts and avoids installation difficulties and poor sealing caused by incorrect specification selection. It also significantly improves production assembly efficiency and system stability.

[0021] Compared to those "multi-functional" fittings that claim to adapt to multiple pipe diameters but have inherent flaws, this fitting eliminates complex adjustment structures such as multi-layer nested pipe diameter adapters and cumbersome threaded adjustment components. Installation is more convenient, requiring less time and effort from operators and significantly reducing the probability of human error. The simple design of rotating the front cover on the rear end makes operation quick and easy, requiring no specialized tools or complex skills. The magnetic ring further enhances the stability of the device, saving significant time and labor costs on production lines and during emergency repairs, reducing production downtime and equipment interruptions. It fundamentally guarantees sealing performance, effectively eliminating safety hazards such as fluid leakage and ensuring the safe and reliable operation of the entire fluid transport system. Furthermore, the simple structural design not only reduces manufacturing costs but also minimizes wear caused by frequent adjustments during long-term use, effectively extending the sealing performance and service life of the fitting, and reducing equipment maintenance frequency and costs.

[0022] 2. This utility model further enhances its performance advantages and brings many significant benefits by creating recessed grooves on the fastening plate and adding a plug ring. First, based on the wide range of pipe diameter adaptability and convenient installation, the insertion of the plug ring greatly enhances the tightness of the connection between the second pipe and the joint assembly, effectively filling the tiny gaps that exist during fastening, greatly improving the sealing performance, and ensuring that there is no risk of leakage when transporting various fluids, including high-pressure liquids and corrosive gases. This effectively guarantees the safe and stable operation of the pipeline system and avoids environmental pollution, energy loss, and potential safety accidents caused by leakage. It is especially important in industries with extremely high sealing requirements, such as chemical, petroleum, and natural gas industries.

[0023] Secondly, this tight connection method enhances the reliability and stability of the connection structure between the joint assembly and the second pipeline, enabling it to maintain a stable connection even when subjected to significant external forces, vibrations, or pressure fluctuations. This reduces equipment failures and downtime caused by loose connections, improves production efficiency and equipment lifespan, and lowers maintenance costs and operational risks. Furthermore, the application of the plug ring further expands the applicability of the joint, allowing it to operate reliably in more complex and demanding working environments. Whether in high-temperature, high-humidity, or high-dust environments, it ensures excellent sealing and connection performance. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0034] Example

[0035] Please refer to Figures 1 to 6 As shown:

[0036] A high-sealing-performance hose connector includes a first pipe 1, a second pipe 2 disposed on one side of the first pipe 1, a rear tail piece 3 fitted onto the second pipe 2, a first through hole 4 on the rear tail piece 3, a limiting piece 5 fixedly connected at equal intervals on the outer ring surface of the rear tail piece 3, a hexagonal groove 6 on the limiting piece 5, a front cover 7 fitted onto the rear tail piece 3, an auxiliary piece 8 fixedly connected to the front end of the front cover 7, a guide groove 9 fixedly opened at equal intervals on the auxiliary piece 8, a second through hole 10 on the auxiliary piece 8, a retaining strip 11 fixedly connected to the inner ring wall of the front cover 7, a sliding post 12 slidably connected to the guide groove 9, a fastening piece 13 fixedly connected to the middle of the sliding post 12, the bottom surface of the sliding post 12 slidably connected to the rear tail piece 3, a recessed groove 14 on the outer side of the fastening piece 13, a plugging ring 15 inserted into the first pipe 1, a third through hole 16 on the plugging ring 15, and a magnetic suction ring 17 fixedly connected onto the rear tail piece 3.

[0037] in:

[0038] The front cover 7 is made of magnetic metal, which can be implemented as iron.

[0039] The retaining strip 11 is used in conjunction with the limiting piece 5, mainly to limit the rotation direction of the front cover 7, so as to prevent it from rotating in the opposite direction and affecting the tightness and sealing between the pipes.

[0040] The sliding column 12 is slidably fitted into the guide groove 9.

[0041] The outer circumferential surface of the plug ring 15 has slightly raised teeth that fit into the recessed groove 14, thereby enhancing the fixation of the second pipe 2.

[0042] The first through hole 4, the second through hole 10, and the third through hole 16 are mainly used for the flow of aqueous solutions.

[0043] The magnetic ring 17 is mainly used to magnetically attract the front cover 7, thereby assisting in the stable mounting of the front cover 7 on the rear tail piece 3.

[0044] Working principle:

[0045] Initial state: The front cover 7 with auxiliary plate 8 is magnetically attached to the rear tail piece 3 by magnetic ring 17.

[0046] In use, first insert the plug ring 15 into the second pipe 2, then place the second pipe 2 with the plug ring 15 into the second through hole 10 on the auxiliary piece 8. Then, rotate the front cover 7. At this time, the front cover 7 will rotate with the fixedly connected auxiliary piece 8. During this process, the retaining strip 11 fixedly connected to the inner ring wall of the front cover 7 and the limiting piece 5 fixedly connected at equal distances to the outer ring surface of the rear tail piece 3 serve as anti-reverse auxiliary. Furthermore, during the rotation of the auxiliary piece 8, the sliding column 12 in the guide groove 9 on the auxiliary piece 8 will move during the rotation of the auxiliary piece 8. With the assistance of the hexagonal groove 6, the sliding column 12 will move with the fastening piece 13 fixedly connected to it. That is, at this time, the fastening piece 13 will gradually approach the second pipe 2 located in the guide groove 9 under the interaction of the adjacent fastening pieces 13, and finally contact and fasten the second pipe 2. It should be noted that during this fastening process, the recessed groove 14 on the fastening piece 13 will cooperate with the plug ring 15 to achieve high sealing performance of this hose connector assembly.

[0047] Furthermore, through the design of the overall device, compared with the traditional hose fittings that only adapt to a single pipe diameter, this fitting can flexibly adapt to multiple pipe diameters. In the coolant delivery pipeline system of automobile manufacturing and other fields, there is no need to stock a large number of fittings of different specifications, which greatly reduces the inventory management cost of parts, avoids installation difficulties and poor sealing caused by incorrect specification selection, and significantly improves production assembly efficiency and system stability.

[0048] Compared to those "multi-functional" connectors that claim to adapt to multiple pipe diameters but have inherent flaws, this connector eliminates complex adjustment structures, such as multi-layer nested pipe diameter adapters and cumbersome threaded adjustment components. Installation is extremely convenient, requiring minimal time and effort from operators and significantly reducing the probability of human error. The simple design of rotating the front cover 7 on the rear tail piece 3 makes operation quick and easy, requiring no specialized tools or complex skills. Furthermore, the magnetic ring 17 magnetically attracts the front cover 7, increasing the stability of the device. This significantly saves time and labor costs during production assembly lines and emergency repairs, reducing production downtime and equipment interruptions. It fundamentally guarantees sealing performance, effectively eliminating safety hazards such as fluid leakage and ensuring the safe and reliable operation of the entire fluid transport system. Simultaneously, the simple structural design not only reduces manufacturing costs but also minimizes wear caused by frequent adjustments during long-term use, effectively extending the connector's sealing performance and service life, and reducing equipment maintenance frequency and costs.

[0049] Furthermore, by creating a recessed groove 14 on the fastening plate 13 and adding a plug ring 15, its performance advantages are further enhanced, bringing many significant benefits. First, based on the wide range of pipe diameter adaptability and convenient installation, the insertion of the plug ring 15 greatly enhances the tightness of the connection between the second pipe 2 and the joint assembly, effectively filling the tiny gaps that exist during fastening, greatly improving the sealing performance, ensuring no leakage risk when transporting various fluids, including high-pressure liquids and corrosive gases, effectively guaranteeing the safe and stable operation of the pipeline system, and avoiding environmental pollution, energy loss, and potential safety accidents caused by leakage. This is especially important in industries with extremely high sealing requirements, such as chemical, petroleum, and natural gas industries.

[0050] Secondly, this tight connection method enhances the reliability and stability of the overall connection structure between the joint assembly and the second pipe 2, enabling it to maintain a stable connection even when subjected to large external forces, vibrations, or pressure fluctuations. This reduces equipment failures and downtime caused by loose connections, improves production efficiency and equipment lifespan, and lowers maintenance costs and operational risks. Furthermore, the application of the plug ring 15 further expands the applicability of the joint, enabling it to operate reliably in more complex and demanding working environments. Whether in high-temperature, high-humidity, or high-dust environments, it ensures good sealing and connection performance.
