Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection technology, and in particular relates to a quick coupling assembly. Background Technology

[0002] A double-ended male threaded connector is a pipe fitting used for pipe connections. Both ends of the connector have external threads, allowing it to connect with other pipe fittings or equipment with internal threads. The connection is achieved through threaded rotation, requiring no complex tools or professional skills. It is simple to operate and can quickly complete pipe connection and disassembly. To increase the sealing and strength of the connection between the double-ended male threaded connector and the pipe, we have designed a quick-connect assembly. It uses a double-layer sealing ring to ensure the sealing of the connection, and the pipe end extends into the outer ring to improve the connection strength. Utility Model Content

[0003] The purpose of this invention is to provide a quick connector assembly that has the advantages of using a double-layer sealing ring to ensure the sealing of the connection and the pipe end extending into the outer ring to improve the connection strength, so as to solve the above-mentioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A quick connector assembly includes an external threaded tube connected between two pipe bodies. A hexagonal rotating block is fixedly connected to the middle of the surface of the external threaded tube. Both ends of the pipe body are provided with concave cavities. A sealing ring is installed in the inner cavity of the concave cavity. The surface of the external threaded tube is provided with an external thread. The inner cavity of the pipe body is provided with an internal thread that matches the external thread. A reinforcing ring is welded to the top and bottom of the hexagonal rotating block. A sealing ring is provided in the inner cavity of the reinforcing ring that fits against the hexagonal rotating block. One end of the pipe body near the external threaded tube extends into the inner cavity of the reinforcing ring and abuts against the sealing ring.

[0005] Preferably, a limiting ring is fixedly connected to the bottom of one surface of the sealing ring, and a limiting groove adapted to the limiting ring is provided at the bottom of the inner cavity of the concave cavity.

[0006] Preferably, both ends of the pipe body are provided with external bevels.

[0007] Preferably, the end of the pipe body near the external threaded tube is provided with an inner bevel.

[0008] Preferably, the outer diameter of the pipe body is the same as the inner diameter of the reinforcing ring.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model involves inserting a second sealing ring into a reinforcing ring and installing a first sealing ring in the inner cavity of a recess. The external threaded tube is then lifted and screwed between the two pipe bodies until the end of the pipe body extends into the inner cavity of the reinforcing ring, squeezing the second sealing ring. At this time, the first sealing ring at the end of the external threaded tube is squeezed against the inner wall of the pipe body, achieving a double-layer seal. The pipe body extends into the inner wall of the reinforcing ring, increasing the connection strength between the pipe body and the external threaded tube. This achieves the purpose of ensuring the sealing performance of the connection with a double-layer sealing ring and increasing the connection strength by extending the pipe end into the outer ring.

[0011] 2. In this utility model, by using the combination of the limiting ring and the limiting groove, when the sealing ring is installed in the inner cavity of the concave cavity, the limiting ring on the surface of the sealing ring will enter the inner cavity of the limiting groove to limit the sealing ring and prevent the sealing ring from falling out of the inner cavity of the concave cavity due to its own weight.

[0012] 3. By setting the external bevel, this utility model enables the end of the external threaded tube to enter part of the pipe body when it comes into contact with the pipe body, thereby making it easier for the external thread on the external threaded tube to engage with the internal thread on the pipe body.

[0013] 4. By setting the inner inclined surface, the inner inclined surface on the pipe body will cause the sealing ring two to gather and deform towards the center and be squeezed onto the surface of the external threaded pipe when the sealing ring two is squeezed, thus improving the sealing effect.

[0020] In the following description, embodiments of the quick connector assembly of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-3 This invention illustrates a quick-connect assembly according to an embodiment of the present invention. It includes an externally threaded tube 2 connecting two pipe bodies 1. A hexagonal rotating block 3 is fixedly connected to the middle of the surface of the externally threaded tube 2. Both ends of the pipe body 1 have recesses 4. A sealing ring 5 is installed inside the cavity of the recess 4. A limiting ring 10 is fixedly connected to the bottom of the surface of the sealing ring 5. A limiting groove 11 adapted to the limiting ring 10 is provided at the bottom of the cavity of the recess 4. Through the cooperation of the limiting ring 10 and the limiting groove 11, when the sealing ring 5 is installed in the cavity of the recess 4, the limiting ring 10 on the surface of the sealing ring 5 will enter the cavity of the limiting groove 11, limiting the sealing ring 5 and preventing it from falling out of the cavity of the recess 4 due to its own weight. The surface of the externally threaded tube 2 is provided with an external thread 6, and the cavity of the pipe body 1 is provided with an internal thread 7 adapted to the external thread 6. Both ends of the pipe body 1 are provided with... An outer bevel 12 is provided. By setting the outer bevel 12, when the end of the external threaded tube 2 contacts the pipe body 1, the end of the external threaded tube 2 will enter part of the pipe body 1, thereby making it easier for the external thread 6 on the external threaded tube 2 to engage with the internal thread 7 on the pipe body 1. The top and bottom of the hexagonal swivel block 3 are welded with reinforcing rings 8. The inner cavity of the reinforcing ring 8 is provided with a sealing ring 9 that fits against the hexagonal swivel block 3. The end of the pipe body 1 near the external threaded tube 2 extends into the inner cavity of the reinforcing ring 8 and abuts against the sealing ring 9. The outer diameter of the pipe body 1 is the same as the inner diameter of the reinforcing ring 8. The end of the pipe body 1 near the external threaded tube 2 is provided with an inner bevel 13. By setting the inner bevel 13, when the inner bevel 13 on the pipe body 1 compresses the sealing ring 9, the sealing ring 9 will be deformed and squeezed towards the center and pressed against the surface of the external threaded tube 2, thereby improving the sealing effect.

[0022] Working principle: When using this utility model, a second sealing ring 9 is inserted into the reinforcing ring 8 and a first sealing ring 5 is installed in the inner cavity of the recess 4. The external threaded tube 2 is picked up and screwed between the two pipe bodies 1. Due to the cooperation of the internal thread 7 and the external thread 6, the two pipe bodies 1 move towards each other until the end of the pipe body 1 extends into the inner cavity of the reinforcing ring 8 and squeezes the second sealing ring 9. At this time, the first sealing ring 5 at the end of the external threaded tube 2 is squeezed on the inner wall of the pipe body 1, achieving a double seal. At this time, the pipe body 1 extends into the inner wall of the reinforcing ring 8, and the outer side of the pipe body 1 is in contact with the inner wall of the reinforcing ring 8, which increases the connection strength between the pipe body 1 and the external threaded tube 2.

[0023] In summary, this quick-connect assembly achieves a double seal by inserting a second sealing ring 9 into the reinforcing ring 8 and installing a first sealing ring 5 inside the recess 4. The external threaded tube 2 is then lifted and screwed between the two pipe bodies 1 until the end of the pipe body 1 extends into the inner cavity of the reinforcing ring 8, compressing the second sealing ring 9. At this point, the first sealing ring 5 at the end of the external threaded tube 2 is pressed against the inner wall of the pipe body 1, achieving a double seal. The pipe body 1 extends into the inner wall of the reinforcing ring 8, increasing the connection strength between the pipe body 1 and the external threaded tube 2. This achieves the goal of ensuring a tight seal with double sealing rings and increasing connection strength by extending the pipe end into the outer ring.
