Description

Technical Field

[0001] This utility model relates to the field of pipeline connection fittings technology, and relates to a connector that can quickly connect or disconnect pipelines. Background Technology

[0002] In industrial production, equipment cleaning, and fluid transportation, quick couplings are core components for rapidly connecting and disconnecting pipelines, and their performance directly affects operational efficiency and safety. Currently, traditional quick couplings on the market, in order to achieve unidirectional flow, generally integrate check valve structures (such as valve cores and valve discs) into their internal flow channels, leading to the following key technical defects: 1. The check valve structure and its supporting components (such as springs and seals) occupy the internal space of the flow channel, which reduces the actual flow diameter of the same model of quick connector. During media transmission, pressure loss is easily caused by the obstruction of the components, which cannot meet the high flow requirements of high-pressure flushing pipelines (such as industrial cleaning machines and high-pressure water guns), resulting in reduced flushing efficiency and increased energy consumption. 2. Traditional quick couplings have a large number of internal components (including check valve core, auxiliary seals, guide structure, etc.) and complex assembly relationships. Once a fault such as leakage or jamming occurs, the entire coupling must be disassembled for repair, which is cumbersome and time-consuming. Utility Model Content

[0003] This invention addresses the problems of existing technologies by providing a connector that can quickly connect or disconnect pipelines.

[0004] The purpose of this utility model can be achieved through the following technical solution: a connector that can quickly connect or disconnect pipelines, including a female connector and a male connector that cooperate with each other; The female connector is assembled from an outer ring, a female connector body, an O-ring, a steel ball, a retaining ring, and a spring. The outer ring is movably fitted on the outside of the female connector body. The spring is located between the outer ring and the female connector body. The O-ring is embedded in the inner sealing position of the female connector body. The female connector body has a mounting hole for receiving the steel ball. The retaining ring is located on the outside of the female connector body and inside the outer ring. One end of the male connector is provided with a plug end, and the outer circumferential surface of the plug end is provided with a trapezoidal snap-fit ​​surface. The outer circumferential surface of the trapezoidal snap-fit ​​surface is provided with a sealing surface and an annular groove in sequence. The sealing surface is used to fit and seal with the O-ring in the female connector, and the annular groove is used to cooperate with the steel ball in the female connector to achieve locking. The other end of the male connector is a pipeline connection end for connecting to an external pipeline.

[0005] As a further improvement, the outer surface of the outer ring is provided with a knurled structure and its shape is smooth.

[0006] In a further improvement, the steel balls are provided in multiple quantities, and the multiple steel balls are evenly distributed along the circumference of the female connector body.

[0007] As a further improvement, all metal surfaces in the female connector that come into contact with the O-ring are rounded.

[0008] In a further improvement, the male connector has a through-hole along its axial direction, and the through-hole cooperates with the internal flow channel of the female connector to form a through-diameter structure.

[0009] Further improvements include the outer ring, female connector body, steel ball, snap ring, and male connector all being made of 316 stainless steel.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The trapezoidal snap-fit ​​surface of the male connector of this utility model can guide the plug end to be accurately inserted into the female connector, avoiding misalignment and jamming. The knurled design of the outer ring increases the friction of the hand, so that it can be pushed stably even if the hand is covered with media, further improving the ease of operation. 2. The O-ring of this utility model fits tightly with the sealing surface of the male connector, and all metal surfaces in contact with the O-ring are rounded to avoid scratching the O-ring and extend its service life. At the same time, the O-ring is made of corrosion-resistant material and can be used with a variety of media (such as acid and alkali solutions, high-temperature fluids), reducing leakage caused by damage to the seal. 3. The internal flow channel of this utility model connector is designed with a through diameter, eliminating ineffective components such as the check valve structure of traditional connectors. The flow channel diameter is larger, and there are no extra parts to obstruct the flow of the medium, which can meet the high flow rate requirements of high-pressure flushing pipelines. 4. The O-ring replacement of this utility model does not require disassembling the entire connector. Only the outer ring needs to be pushed and the male connector pulled out, and the old O-ring can be directly removed and replaced with a new one, reducing maintenance labor costs. 5. The snap ring of this utility model is located on the outside of the female connector body and inside the outer ring, which can limit the sliding stroke of the outer ring, prevent the outer ring from falling off, and improve the safety of use. At the same time, the connector has a smooth shape design without sharp edges, which makes it less likely to scratch operators or surrounding equipment. Attached Figure Description

[0016] Example 1 A connector that can quickly connect or disconnect pipelines includes: a female connector 1 and a male connector 2 that cooperate with each other; The female connector 1 is assembled from an outer ring 11, a female connector body 12, an O-ring 13, a steel ball 14, a retaining ring 15, and a spring 16. The outer ring 11 is movably sleeved on the outside of the female connector body 12. The spring 16 is located between the outer ring 11 and the female connector body 12. The O-ring 13 is embedded in the inner sealing position of the female connector body 12. The female connector body 12 has a mounting hole 121 for accommodating the steel ball 14. The retaining ring 15 is located on the outside of the female connector body 12 and inside the outer ring 11. One end of the male connector 2 is provided with a plug end 21. The outer circumferential surface of the plug end 21 is provided with a trapezoidal snap-fit ​​surface 211. The outer circumferential surface of the trapezoidal snap-fit ​​surface 211 is provided with a sealing surface 22 and an annular groove 23 in sequence. The sealing surface 22 is used to fit and seal with the O-ring 13 in the female connector 1. The annular groove 23 is used to cooperate with the steel ball 14 in the female connector 1 to achieve locking. The other end of the male connector 2 is a pipeline connection end for connecting to an external pipeline.

[0017] As a further preferred embodiment, the outer surface of the outer ring 11 is provided with a knurled structure and its shape is smooth.

[0018] As a further preferred embodiment, there are multiple steel balls 14, which are evenly distributed along the circumferential direction of the female connector body 12.

[0019] As a further preferred embodiment, all metal surfaces of the female connector 1 that come into contact with the O-ring 13 are rounded.

[0020] As a further preferred embodiment, the male connector 2 has a through flow channel hole along its axial direction inside, and the flow channel hole cooperates with the flow channel inside the female connector 1 to form a through-diameter structure.

[0021] As a further preferred embodiment, the outer ring 11, the female connector body 12, the steel ball 14, the retaining ring 15, and the male connector 2 are all made of 316 stainless steel.

[0022] like Figures 1-3 As shown, in practical use, this utility model... When the pipeline is connected: First, manually push the outer ring 11 of the female connector 1 downwards. The outer ring 11 slides along the outside of the female connector body 12, squeezing the spring 16 located between the two, so that the spring 16 is compressed and stores elastic force. At the same time, the inner side of the outer ring 11 disengages from the steel ball 14, releasing the restriction on the steel ball 14. The steel ball 14 can move freely in the mounting hole 121 of the female connector body 12. Next, insert the male connector 2 with the opening end 21 aligned with the female connector 1 until the sealing surface 22 of the male connector 2 is fully fitted with the O-ring 13 inside the female connector body 12. At this time, the annular groove 22 of the male connector 2 is just aligned with the mounting hole 121 of the female connector body 12, which is a reserved position for locking the steel ball 14. Finally, release the hand that was pushing the outer ring 11, and the spring 16 releases the stored elastic force, pushing the outer ring 11 back to its original position along the female connector body 12; the inner side of the outer ring 11 presses the steel ball 14 again, pushing the steel ball 14 into the annular groove 22 of the male connector 2, thus achieving mechanical locking between the female connector 1 and the male connector 2; at the same time, the O-ring 13 fits tightly with the sealing surface 22 to form a pipeline seal, completing the connection between the two pipeline sections, and allowing the medium to be filled into the pipeline for transmission.

[0023] When the pipeline is disconnected: First, manually push the outer ring 11 of the female connector 1 downwards to compress the spring 16. The inner side of the outer ring 11 separates from the steel ball 14, and the steel ball 14 disengages from the annular groove 22 of the male connector 2, thus releasing the lock. Next, directly pull the male connector 2's insertion end 21 out of the female connector 1, the O-ring 13 separates from the sealing surface 22, the two sections of the pipeline are disconnected, the outer ring 11 is loosened, the spring 16 pushes the outer ring 11 to reset, and waits for the next connection.

[0024] This utility model has the following beneficial effects: 1. The trapezoidal snap-fit ​​surface 211 of the male connector 2 can guide the plug end 21 to be accurately inserted into the female connector 1, avoiding misalignment and jamming. The knurled design of the outer ring 11 increases the friction of the hand, so that it can be pushed stably even if the hand is covered with media, further improving the ease of operation. 2. The O-ring 13 fits tightly against the sealing surface 22 of the male connector 2, and all metal surfaces in contact with the O-ring 13 are rounded to avoid scratching the O-ring 13 and extend its service life. At the same time, the O-ring 13 is made of corrosion-resistant material and can be used with a variety of media (such as acid and alkali solutions, high-temperature fluids) to reduce leakage caused by damage to the seal. 3. The internal flow channel of the connector is designed with a through diameter, eliminating ineffective components such as the check valve structure of traditional connectors. The flow channel diameter is larger, and there are no extra parts to obstruct the flow of the medium, which can meet the high flow rate requirements of high-pressure flushing pipelines. 4. Replacing O-ring 13 does not require disassembling the entire connector. Simply push the outer ring 11 and pull out the male connector 2 to directly remove the old O-ring 13 and replace it with a new one, reducing maintenance labor costs. 5. The retaining ring 15 is located on the outside of the female connector body 12 and inside the outer ring 11. It can limit the sliding stroke of the outer ring 11, prevent the outer ring 11 from falling off, and improve the safety of use. At the same time, the connector has a smooth shape design without sharp edges, which makes it less likely to scratch operators or surrounding equipment.
