Description

Technical Field

[0001] This utility model relates to the field of quick connector technology, and in particular to a quick connector that facilitates positioning and connection. Background Technology

[0002] The biggest advantage of quick couplings lies in their design for quick connection and disassembly. Compared to traditional threaded connections, they can be connected and disassembled much faster, thus greatly improving the efficiency of pipe repair and replacement. In pipe repair, the male and female connectors are usually installed on two pipes and then connected by snapping them together. However, due to the weight of the pipes connected to the connectors, the alignment of the male and female connectors is very inconvenient when snapping them together.

[0003] Therefore, a quick connector that facilitates positioning and connection is proposed. Utility Model Content

[0004] The purpose of this invention is to address the inconvenience of alignment in existing technologies by proposing a quick connector that facilitates positioning and connection.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A quick connector for easy positioning and connection includes a first upright plate and a second upright plate. A locking ring is rotatably mounted on the top of the first upright plate. A male head is mounted on the inner wall of the locking ring. A first positioning plate is fixedly mounted on one side of the male head. A common connecting rod is rotatably mounted between the first and second upright plates. A connecting plate is slidably connected to the circumference of the connecting rod. Positioning rings are fixedly mounted on both ends of the connecting plate. A female head is mounted on the inner wall of one of the positioning rings. The female head and the male head are inserted into each other. A fixing ring is fixedly mounted inside the male head. A sealing ring is provided on one side of the fixing ring. Sealing is achieved by the female head pressing against the sealing ring.

[0007] In one possible design, a second positioning plate is fixedly mounted on the circumference of the female connector. The second positioning plate works in conjunction with the first positioning plate to fix the male and female connectors together with bolts.

[0008] In one possible design, two sliding rods are fixedly installed on the circumference of the female head, and two symmetrical sliding grooves are provided on the circumference of the male head. The sliding grooves are arc-shaped, and the sliding rods slide inside the sliding grooves.

[0009] In one possible design, a fixing block is fixedly mounted on one end of the connecting rod, and the same spring is installed on the side of the fixing block that is close to the connecting plate. The spring is used to drive the connecting plate to reset.

[0010] In one possible design, a handwheel is rotatably mounted on the side of the second upright plate. The handwheel passes through the second upright plate and is fixedly connected to the connecting rod, and is used to drive the connecting rod to rotate.

[0011] In one possible design, a flange is fixedly installed on one side of both the male and female connectors for connecting water pipes.

[0012] In this application, two pipes to be connected are connected to a male and a female connector respectively via flanges. After connection, the male connector is placed in the locking ring and fixed with bolts. Then, the female connector is installed in the positioning ring. After installation, the handwheel is turned, which drives the connecting rod to rotate. The connecting rod drives the connecting plate and the female connector to rotate. When the rotation reaches a certain angle, the outer wall of the female connector touches the inner wall of the first positioning plate. At this point, the handwheel is stopped, and the connecting plate is pushed. The two sliding rods around the circumference of the female connector slide in the two grooves of the male connector. After moving a short distance, the female connector is rotated, and the sliding rods continue to move along the slope of the grooves. At the same time, one end of the female connector begins to press the sealing ring on the side of the fixing ring. Through compression, a good sealing effect is achieved between the two connectors. When the sliding rods slide to the end of the groove, the second positioning plate is exactly in contact with the first positioning plate. At this point, the first positioning plate and the second positioning plate are fixed with bolts. If it is necessary to separate the male and female connectors, the bolts between the first and second positioning plates are removed, and the connecting plate is reset by a spring. There is no need to manually pull it back, saving time.

[0013] Beneficial effects:

[0014] In this utility model, the quick connector that facilitates positioning and connection is provided by installing a first positioning plate on one side of the male connector. When the connecting plate rotates at a certain angle, the outer wall of the female connector comes into contact with and fits against the inner wall of the first positioning plate. At this time, the male and female connectors can be plugged in.

[0015] In this invention, the quick connector that facilitates positioning and connection has a groove with a certain slope. When the female head is rotated, the slide rod rotates along the slope of the groove and moves forward at the same time, pressing the sealing ring to improve the sealing effect between the male and female heads.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1

[0023] Reference Figure 1-Figure 4 A quick connector includes: a first upright plate 1 and a second upright plate 17. A locking ring 2 is rotatably mounted on the top of the first upright plate 1. A male head 3 is mounted on the inner wall of the locking ring 2. A first positioning plate 5 is fixedly mounted on one side of the male head 3. A common connecting rod 6 is rotatably mounted between the first upright plate 1 and the second upright plate 17. A connecting plate 7 is slidably connected to the circumference of the connecting rod 6. Positioning rings 8 are fixedly mounted on both ends of the connecting plate 7. A female head 9 is mounted on the inner wall of one of the positioning rings 8. The female head 9 and the male head 3 are inserted into each other. A fixing ring 15 is fixedly mounted inside the male head 3. A sealing ring 16 is provided on one side of the fixing ring 15. A seal is achieved by the female head 9 pressing the sealing ring 16.

[0024] In this embodiment, positioning rings 8 are installed at both ends of the connecting plate 7. When a female head 9 is installed in one of the positioning rings 8, the other positioning ring 8 can also act as a handle. People can rotate the empty positioning ring 8 to make the connecting rod 6 rotate. When the female head 9 is inserted into the male head 3, the female head 9 rotates and squeezes the sealing ring 16 with increasing pressure, so that a good sealing effect is formed between the male head 3 and the female head 9, and there will be no leakage at the connection.

[0025] Reference Figure 1-Figure 2 A second positioning plate 10 is fixedly installed around the circumference of the female head 9. The second positioning plate 10 is used in conjunction with the first positioning plate 5 to fix the male head 3 and the female head 9 by bolts.

[0026] Reference Figure 1-Figure 2 Two sliding rods 11 are fixedly installed on the circumference of the female head 9, and two symmetrical sliding grooves 4 are provided on the circumference of the male head 3. The sliding grooves 4 are arc-shaped, and the sliding rods 11 slide inside the sliding grooves 4.

[0027] In this embodiment, the front half of the slide groove 4 is a straight groove and the rear half is an arc-shaped groove. When the female head 9 moves, the slide rod 11 first contacts and slides with the straight groove of the front half of the slide groove. When the female head 9 needs to be rotated, the slide rod 11 contacts and slides with the arc-shaped groove of the rear half of the slide groove 4, and continues to move while sliding. When the slide rod 11 slides to the end of the slide groove 4, the first positioning plate 5 just releases its contact with the second positioning plate 10. At this time, the first positioning plate 5 and the second positioning plate 10 are fixed by bolts to prevent the female head 9 from sliding out of the male head 3.

[0028] Reference Figure 1 A fixing block 14 is fixedly installed on one end of the connecting rod 6. The fixing block 14 and the connecting plate 7 are close to each other and are equipped with the same spring 12. The spring 12 is used to drive the connecting plate 7 to reset.

[0029] In this embodiment, when it is necessary to separate the male head 3 and the female head 9, it is only necessary to remove the bolt between the first positioning plate 5 and the second positioning plate 10. The spring 12 pulls the slide rod 11 out of the slide groove 4, and then drives the connecting plate 7 to reset.

[0030] Reference Figure 2 A handwheel 13 is rotatably mounted on the side of the second upright plate 17. The handwheel 13 passes through the second upright plate 17 and is fixedly connected to the connecting rod 6, and is used to drive the connecting rod 6 to rotate.

[0031] In this embodiment, the handwheel 13 is made of a non-slip material to prevent the hand from slipping when rotating.
