Description

Technical Field

[0001] This utility model relates to the field of pipe connection fittings technology, specifically a leak-proof hose connector. Background Technology

[0002] In many fields involving fluid transportation, hoses are widely used due to their advantages such as good flexibility and bendability. As a key component connecting hoses to other pipes or equipment, the sealing performance of hose fittings directly affects the normal operation of the entire fluid transportation system. Therefore, developing a leak-proof hose fitting is particularly important.

[0003] A hose connector with reference announcement number CN203656418U includes a threaded body and a nut fitted thereon. One end of the threaded body is provided with an external thread, and the other end of the threaded body is an arc-shaped end. A groove is provided between the external thread and the end. This hose connector is tightly locked when fitted, with good reliability and fitting performance, and a long service life. As can be seen from the above, although this hose connector can be well applied, it is usually not convenient to seal the connection area of ​​the hose, making it easy for leakage to occur during the fluid transportation process, which often troubles users.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4 One embodiment of this utility model is a leak-proof hose connector, which includes a connector body 1, a filling pipe 2 fixed at the center of the top of the connector body 1, and the bottom end of the filling pipe 2 connected to the top of the connector body 1.

[0022] In use, the purification liquid is filled into the inside of the connector body 1 through the filling pipe 2;

[0023] The inner wall of the filling pipe 2 is provided with internal thread 4, and a reinforcing ring 3 is installed at the connection position between the filling pipe 2 and the pipe body 1;

[0024] In use, the connection strength between the filling pipe 2 and the connecting pipe body 1 is improved by setting the reinforcing ring 3;

[0025] The outer wall of one end of the connector body 1 is provided with a first external thread 5, and the outer wall of the other end of the connector body 1 is provided with a second external thread 6. A first nut connector 7 is threadedly installed on the outer wall of the connector body 1 at the position of the first external thread 5. A first hose connector 8 is fixedly installed on one end of the first nut connector 7. The inner wall of one end of the first hose connector 8 is in contact with the outer wall of one end of the connector body 1. A mounting base 16 is fixed at the bottom end of the first hose connector 8. A hanging hole 18 is provided inside the mounting base 16. Both ends of the hanging hole 18 extend to the outside of the mounting base 16.

[0026] In use, the hose connector can be hung and carried as a whole via the mounting base 16 through the hanging hole 18.

[0027] The first hose connector 8 is fixedly installed at one end away from the first nut connector 7. The second nut connector 10 is threaded on the outer wall of the connector body 1 at the position of the second external thread 6. The second hose connector 11 is fixedly installed at one end of the second nut connector 10. The inner wall of one end of the second hose connector 11 is in contact with the outer wall of one end of the connector body 1. The outer walls on both sides of the second hose connector 11 are provided with a mounting seat 13. A connecting handle 14 is rotatably installed on the inner wall of the mounting seat 13.

[0028] In use, the handle 14 is provided to accommodate the handle hole 17.

[0029] The connecting handle 14 has a handle hole 17 inside at the end away from the mounting base 13. Both ends of the handle hole 17 extend to the outside of the connecting handle 14. A lifting ring 15 is installed on the outer wall of the connecting handle 14 at the location of the handle hole 17.

[0030] When in use, the lifting ring 15 allows for easy handling and carrying of the entire hose connector;

[0031] The second hose connector 11 is fixedly installed with the second hose body 12 at the end away from the second nut connector 10.

[0032] In this embodiment, the first nut connector 7 and the second nut connector 10 are screwed onto the outer walls of both ends of the connector body 1 at the positions of the first external thread 5 and the second external thread 6, respectively. This causes both ends of the connector body 1 to contact the inner walls of the first hose connector 8 and the second hose connector 11, thereby connecting the first hose body 9 and the second hose body 12 to both ends of the connector body 1. This facilitates quick installation of the first hose body 9 and the second hose body 12 and allows for sealing of the connection area between the first hose body 9 and the second hose body 12 and the connector body 1. Furthermore, both the first hose connector 8 and the second hose connector 11 consist of an outer tube and an inner rubber ring to ensure proper connection between the two ends of the connector body 1 and the first hose connector 8 and the second hose connector 11. To meet the sealing requirements between the pipe fittings 11, a filling pipe 2 is connected to the top of the connecting pipe body 1. An internal thread 4 is provided on the inner wall of the filling pipe 2, allowing the external threaded pipe to be installed and connected to the filling pipe 2 by threaded installation. Purification agents are then injected into the connecting pipe body 1 through the filling pipe 2 to improve the functionality of the hose fitting. Finally, a connecting handle 14 is movably mounted on the inner wall of the mounting base 13, and a lifting ring 15 is fitted on the outer wall of the connecting handle 14 at the handle hole 17 position, allowing the hose fitting to be picked up and carried from the left end. Since the hanging base 16 at the bottom of the first hose fitting 8 has a hanging hole 18 inside, the hose fitting can be hung and carried from the right end through the hanging hole 18, thus completing the use of the hose fitting.
