Description

Technical Field

[0001] This invention belongs to the field of hose connector technology, and particularly relates to a waterproof hose connector based on a high-tightness interlocking structure. Background Technology

[0002] Pipe fittings, as an indispensable key component in piping systems, play a vital role in both industrial production and civil applications. They are essential connecting tools between pipes and detachable connection points between components and pipes, making the installation, maintenance, and modification of piping systems much more convenient. Among various pipe fittings, pipe fittings occupy a crucial position due to their high frequency of use and wide range of applications. As a common item in hardware products, pipe fittings have a huge market demand and are widely used in petrochemical, water supply and drainage, HVAC, and machinery equipment industries.

[0003] With the development of industrial technology, there are increasingly more types of pipe fittings on the market. According to the material, they can be divided into metal pipe fittings, plastic pipe fittings, and composite material pipe fittings; according to the function, they can be divided into ordinary pipe fittings, quick couplings, rotary couplings, etc.; according to the connection method, they can be divided into threaded connections, flange connections, compression fittings, and many other types.

[0004] Waterproof hose connectors based on a high-tightness interlocking structure have attracted much attention due to their special structural design, especially suitable for applications requiring waterproof sealing. However, traditional waterproof hose connectors have certain design limitations. Existing equipment often uses only a single-layer sealing structure between the connectors. While simple and easy to use, this can easily lead to incomplete sealing in practical applications, particularly under high pressure, vibration, or significant temperature variations. A single-layer sealing structure can easily create tiny gaps, resulting in media leakage. Therefore, designing waterproof hose connectors based on a high-tightness interlocking structure is essential. Summary of the Invention

[0005] This invention provides a waterproof hose connector based on a high-tightness interlocking structure, which aims to solve the problem that single-layer sealing structures are prone to generating tiny gaps, leading to media leakage.

[0006] The present invention is implemented as follows: a waterproof hose connector based on a high-tightness meshing structure includes a first connector and a second connector. One end of the first connector is connected to a first hose via a first fixing member, and one end of the second connector is connected to a second hose via a second fixing member. The other end of the first connector has an arc-shaped groove, and the other end of the second connector is fixedly connected to a sealing ring, which mates with the arc-shaped groove. The other end of the first connector has a toothed groove, and the other end of the second connector is fixedly connected to a toothed ring, which meshes with the toothed groove. Both the first and second connectors are fixedly connected to a protective mechanism. The protective mechanism includes a second groove frame, which is fixedly connected to the first connector. A movable ring is slidably connected inside the second groove frame. Two parallel limiting holes are opened on the second groove frame. An elastic limiting block is connected to the movable ring, and the elastic limiting block cooperates with the limiting holes.

[0007] Preferably, the first fixing member includes a first groove frame, which is fixedly connected to one end of the first connector. A first flexible tube is inserted into the first groove frame. A plurality of fixing tubes are connected at equal intervals along the axis of the first groove frame. A perforated plate is fixedly connected inside each fixing tube. A threaded rod is connected to the hole of each perforated plate. A handle sleeve is fixedly connected to the upper end of each threaded rod. Each handle sleeve is fitted onto a corresponding fixing tube. A compression ball is fixedly connected to the bottom end of each threaded rod. Each compression ball is in compression contact with the first flexible tube.

[0008] Preferably, a first sealing ring for sealing the gap between the first groove frame and the first hose is connected inside the first groove frame.

[0009] Preferably, the other end of the first connector has a groove, and the other end of the second connector is fixedly connected to a plug ring, wherein the groove and the plug ring cooperate.

[0010] Preferably, the outer side of the first connector is connected to a first external thread, the outer side of the second connector is connected to a second external thread, and a threaded sleeve is connected between the first external thread and the second external thread.

[0011] Preferably, an elastic compression mechanism is connected inside the toothed groove. The elastic compression mechanism includes a movable ring. An installation groove is formed inside the toothed groove. The movable ring is slidably connected to the installation groove. A spring is fixedly connected to the movable ring. One end of the spring is fixedly connected to the installation groove. A second sealing ring is fixedly connected to the movable ring. The second sealing ring is in contact with the toothed ring.

[0012] Preferably, the springs are provided in a plurality of portions and are evenly distributed along the axis of the movable ring.

[0013] Preferably, an air-pressing sealing mechanism is connected inside the arc-shaped groove. The air-pressing sealing mechanism includes a chamber that extends into the first connector. The chamber has several through holes that connect to the arc-shaped groove. A third sealing ring is provided inside the arc-shaped groove and contacts the several through holes. An air guide channel is provided on the chamber, and one end of the air guide channel connects to the arc-shaped groove.

[0014] Preferably, the second groove frame is coated with an anti-corrosion layer.

[0015] Compared with related technologies, the waterproof hose connector based on a high-tightness interlocking structure provided by the present invention has the following beneficial effects: 1. A preliminary seal is formed by the sealing ring and the arc groove, a secondary seal is formed by the toothed groove and the toothed ring, and a tertiary seal is formed by the first external thread, the second external thread and the threaded sleeve. Through multi-stage sealing, the sealing effect between the first joint and the second joint is improved, making it less prone to leakage after the first joint and the second joint are connected.

[0016] 2. The spring is compressed by the movable ring, and the spring generates elastic force. Under the action of the spring elastic force, the second sealing ring is compressed to seal the gap between the toothed ring and the toothed groove, thereby improving the sealing effect.

[0017] 3. After the gas in the chamber is released from the through hole, it squeezes the third sealing ring, causing the third sealing ring to come into contact with the sealing ring. Under the pressure of the gas, the third sealing ring seals the gap between the sealing ring and the arc groove, improving the sealing effect.

[0018] 4. By pulling the movable ring outward, the movable ring extends out of the second groove frame. After the movable ring extends a certain distance, the elastic limiting block is inserted into the limiting hole to limit and fix the movable ring. The extended movable ring covers the handle sleeve to prevent the handle sleeve from colliding with external objects and rotating. Attached Figure Description

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] A preferred embodiment of the waterproof hose connector based on a high-tightness interlocking structure provided by the present invention is as follows: Figures 1 to 11 As shown: The waterproof hose connector based on the high-tightness interlocking structure includes a first connector 1 and a second connector 2. One end of the first connector 1 is connected to a first hose 4 through a first fixing member 3, and one end of the second connector 2 is connected to a second hose 6 through a second fixing member 5. The other end of the first connector 1 is provided with an arc-shaped groove 7, and the other end of the second connector 2 is fixedly connected with a sealing ring 8, which cooperates with the arc-shaped groove 7. The other end of the first connector 1 is provided with a toothed groove 9, and the other end of the second connector 2 is fixedly connected with a toothed ring 10, which engages with the toothed groove 9.

[0024] Both the first connector 1 and the second connector 2 are fixedly connected to a protective mechanism 18. The protective mechanism 18 includes a second groove frame 181, which is fixedly connected to the first connector 1. The second groove frame 181 is coated with an anti-corrosion layer. A movable ring 182 is slidably connected inside the second groove frame 181. Two parallel limiting holes 183 are opened on the second groove frame 181. An elastic limiting block 184 is connected to the movable ring 182, and the elastic limiting block 184 cooperates with the limiting holes 183.

[0025] The other end of the first connector 1 is provided with a groove 11, and the other end of the second connector 2 is fixedly connected with a plug ring 12. The groove 11 and the plug ring 12 cooperate with each other. The outer side of the first connector 1 is connected with a first external thread 13, and the outer side of the second connector 2 is connected with a second external thread 14. A threaded sleeve 15 is connected between the first external thread 13 and the second external thread 14.

[0026] The first fixing component 3 includes a first groove frame 31, which is fixedly connected to one end of the first connector 1. A first flexible tube 4 is inserted into the first groove frame 31. Several fixing tubes 32 are connected at equal intervals along the axis of the first groove frame 31. A perforated plate 33 is fixedly connected inside each fixing tube 32. A threaded rod 34 is connected to the hole of each perforated plate 33. A handle sleeve 35 is fixedly connected to the upper end of each threaded rod 34. Each handle sleeve 35 is fitted onto the corresponding fixing tube 32. A compression ball 36 is fixedly connected to the bottom end of each threaded rod 34. Each compression ball 36 is in compression contact with the first flexible tube 4. A first sealing ring 37 for sealing the gap between the first groove frame 31 and the first flexible tube 4 is connected inside the first groove frame 31.

[0027] In use, the first hose 4 is inserted into the first groove frame 31. The handle sleeve 35 is rotated, which drives the threaded rod 34 to rotate. After the threaded rod 34 rotates, it moves downward under the limit of the hole in the perforated plate 33. The threaded rod 34 drives the extrusion ball 36 to move downward. After the extrusion ball 36 moves downward a certain distance, it contacts the first hose 4 and extrudes and fixes it, thereby fixing the first hose 4 to the first groove frame 31. The first sealing ring 37 seals the gap between the first groove frame 31 and the first hose 4. The second hose 6 is fixed by the second fixing member 5 in the same way.

[0028] When the first connector 1 is connected to the second connector 2, the second connector 2 is rotated, which drives the toothed ring 10 to rotate. During the rotation, the toothed ring 10 connects to the toothed groove 9. After the toothed groove 9 and the toothed ring 10 cooperate, the first connector 1 and the second connector 2 are connected and fixed. When the second connector 2 is fixed to the first connector 1, the sealing ring 8 is inserted into the arc-shaped groove 7. After the sealing ring 8 and the arc-shaped groove 7 cooperate, a seal is formed, which initially seals the gap between the first connector 1 and the second connector 2. The toothed groove 9 and the toothed ring 10 cooperate to form a seal, which provides a secondary seal for the gap between the first connector 1 and the second connector 2. The threaded sleeve 15 is rotated, and the threaded sleeve 15 gradually engages with the first external thread 13. The first external thread 13, the second external thread 14 and the threaded sleeve 15 cooperate to form a seal, which provides a tertiary seal for the gap between the first connector 1 and the second connector 2. Through multi-stage sealing, the sealing effect between the first connector 1 and the second connector 2 is improved, making it less prone to leakage after the first connector 1 and the second connector 2 are connected.

[0029] When it is necessary to rotate the handle sleeve 35, press down on the elastic limiting block 184 to separate the elastic limiting block 184 from the limiting hole 183, push the movable ring 182 to retract into the second groove bracket 181, expose the handle sleeve 35, and make it easy to rotate and fix. After fixing, pull the movable ring 182 outward, the movable ring 182 extends out of the second groove bracket 181. After the movable ring 182 extends a certain distance, the elastic limiting block 184 is inserted into the limiting hole 183 to limit and fix the movable ring 182. The extended movable ring 182 covers the handle sleeve 35 to prevent the handle sleeve 35 from colliding with external objects and rotating.

[0030] In this embodiment, when the toothed groove 9 and the toothed ring 10 cooperate to form a seal, a gap is easily generated between the toothed groove 9 and the toothed ring 10, reducing the sealing effect. (Refer to...) Figure 4 and Figure 7 In a further preferred embodiment of the present invention, an elastic compression mechanism 16 is connected inside the toothed groove 9. The elastic compression mechanism 16 includes a movable ring 162. An installation groove 161 is provided inside the toothed groove 9. The movable ring 162 is slidably connected to the installation groove 161. A spring 163 is fixedly connected to the movable ring 162. One end of the spring 163 is fixedly connected to the installation groove 161. A second sealing ring 164 is fixedly connected to the movable ring 162. The second sealing ring 164 is in contact with the toothed ring 10. Several springs 163 are provided and are evenly distributed along the axis of the movable ring 162.

[0031] When the toothed ring 10 is connected to the toothed groove 9, the toothed ring 10 compresses the second sealing ring 164, the second sealing ring 164 compresses the movable ring 162, and the movable ring 162 compresses the spring 163. The spring 163 generates elastic force after being compressed, and the spring 163 generates elastic force to push the movable ring 162. The movable ring 162 is in close contact with the toothed ring 10 through the second sealing ring 164. Under the action of the elastic force of the spring 163, the second sealing ring 164 is compressed to seal the gap between the toothed ring 10 and the toothed groove 9, thereby improving the sealing effect.

[0032] In this embodiment, when the sealing ring 8 and the arc-shaped groove 7 cooperate to form a seal, the sealing effect is reduced due to the rough surface of the arc-shaped groove 7. (Refer to...) Figure 4 and Figure 9 In a further preferred embodiment of the present invention, an air-pressing sealing mechanism 17 is connected inside the arc-shaped groove 7. The air-pressing sealing mechanism 17 includes a chamber 171, which is opened into the first connector 1. A plurality of through holes 172 are opened on the chamber 171, and the through holes 172 communicate with the arc-shaped groove 7. A third sealing ring 173 is provided inside the arc-shaped groove 7, and the third sealing ring 173 contacts the plurality of through holes 172. An air guide channel 174 is opened on the chamber 171, and one end of the air guide channel 174 communicates with the arc-shaped groove 7.

[0033] During the process of inserting the sealing ring 8 into the arc-shaped groove 7, the gas in the arc-shaped groove 7 is pushed into the gas guide channel 174. The gas in the gas guide channel 174 is introduced into the chamber 171, and the pressure in the chamber 171 increases. After the gas in the chamber 171 is released from the through hole 172, it squeezes the third sealing ring 173, so that the third sealing ring 173 and the sealing ring 8 are squeezed and contacted. Under the pressure of the gas on the third sealing ring 173, the third sealing ring 173 seals the gap between the sealing ring 8 and the arc-shaped groove 7, thereby improving the sealing effect.
