[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a quick-connect device for a rubber hose includes a first hose 1 and a second hose 2. A quick-connect mechanism 3 is provided on the outer side of the first hose 1. The quick-connect mechanism 3 includes a fixing ring 31 fixedly connected to the outer side of the first hose 1. A spring 32 is sleeved on the outer side of the first hose 1 near the front of the fixing ring 31. A connecting ring 33 is slidably connected to the outer side of the first hose 1 near the front of the spring 32. A sliding ring 34 is slidably connected to the outer side of the first hose 1 near the front of the connecting ring 33. A limiting ring 35 is fixedly connected to the front end of the sliding ring 34. A limiting ring 36 is fixedly connected to the outer side of the second hose 2. A limiting groove 37 is formed on the outer side of the limiting ring 36. A limiting block 38 is slidably connected to the inner side of the limiting groove 37. A positioning pin 39 is fixedly connected to the front end of the limiting block 38.

[0021] In this embodiment, the rear end of the spring 32 is fixedly connected to the front end of the fixed ring 31, the front end of the spring 32 is fixedly connected to the rear end of the connecting ring 33, the rear end of the sliding ring 34 is fixedly connected to the front end of the connecting ring 33, the outer diameter of the connecting ring 33 is the same as the outer diameter of the fixed ring 31, the outer diameter of the connecting ring 33 is larger than the outer diameter of the sliding ring 34, the limiting ring 35 is located outside the limiting ring 36, the top view shape of the limiting groove 37 is T-shaped, the upper end of the limiting block 38 is fixedly connected to the inner wall of the limiting ring 35, the positioning pin 39 penetrates the interior of the limiting ring 36, the positioning pin 39 is slidably connected to the limiting ring 36, and the center lines of the first hose 1, the second hose 2, the fixed ring 31, the connecting ring 33, the sliding ring 34, the limiting ring 35, and the limiting ring 36 are located on the same straight line.

[0022] Specifically, pull the connecting ring 33 again, causing it to move towards the fixed ring 31 from the outside of the first hose 1. This causes the connecting ring 33 to compress the spring 32, which in turn causes the connecting ring 33 to move the limiting ring 35 via the sliding ring 34. At this point, the front end of the first hose 1 is exposed. Then, align the rear end of the second hose 2 with the front end of the first hose 1, and release the connecting ring 33. The spring 32, under its elastic action, pushes the connecting ring 33 to move in the opposite direction, and the sliding ring 34 moves the limiting ring 35. This causes the limiting ring 35 to move the limiting block 38 to the middle of the inner side of the limiting groove 37, and press the connecting ring 33 to stop it from moving. Then, slightly rotate the limiting ring 35, causing the connecting ring 33 to rotate from the outside of the first hose 1 and move the limiting block 38 to the other side of the limiting groove 37. Finally, release the connecting ring 33. Spring 32 continues to push the connecting ring 33 to move, causing the limiting block 38 to engage the positioning pin 39 inside the limiting ring 36. Under the elastic action of spring 32, the positioning pin 39 is always engaged inside the limiting ring 36, thus connecting hose 2 to hose 1. By pushing the connecting ring 33 to move under the elastic action of spring 32 and pushing the limiting ring 35 to the outside of the limiting ring 36, the limiting block 38 is positioned inside the limiting groove 37. Then, by rotating the limiting ring 35, the limiting block 38 is moved to the other side of the limiting groove 37, and spring 32 engages the positioning pin 39 inside the limiting ring 36. This achieves the purpose of quickly connecting hose 1 and hose 2, thereby improving the efficiency of workers in connecting hose 1 and hose 2.

[0023] In this embodiment, the second hose 2 is placed at the front end of the first hose 1, and the main body material of both the first hose 1 and the second hose 2 is rubber.

[0024] Specifically, place hose 1 and hose 2 together, apply waterproof material to the front end of hose 1 and the rear end of hose 2 respectively, and press the waterproof material between the front end of hose 1 and the rear end of hose 2 to seal hose 1 and hose 2, thus completing the work of connecting hose 1 to hose 2.

[0025] Working principle:

[0026] In use, first place hose 1 and hose 2 together, respectively. Apply waterproof material to the front end of hose 1 and the rear end of hose 2. Then pull the connecting ring 33, moving it from the outside of hose 1 towards the fixing ring 31. This causes the connecting ring 33 to compress the spring 32, which in turn moves the limiting ring 35 via the sliding ring 34. At this point, the front end of hose 1 is exposed. Then, align the rear end of hose 2 with the front end of hose 1, and then release... Open the connecting ring 33, causing the spring 32 to push the connecting ring 33 in the opposite direction under elastic action, and causing the sliding ring 34 to drive the limiting ring 35 to move. This causes the limiting ring 35 to move the limiting block 38 to the middle of the inner side of the limiting groove 37. Press down on the connecting ring 33 to stop it from moving. Then, slightly rotate the limiting ring 35 to make the connecting ring 33 rotate on the outside of the first hose 1, and move the limiting block 38 to the other side of the limiting groove 37. Then release the connecting ring 33, allowing the spring 32 to continue pushing the connecting ring 33. As the connecting ring 33 moves, the limiting block 38 engages the positioning pin 39 within the limiting ring 36. Furthermore, the elastic action of the spring 32 ensures that the positioning pin 39 remains engaged within the limiting ring 36, thus connecting the second hose 2 to the first hose 1. This causes the front end of the first hose 1 and the rear end of the second hose 2 to press against the waterproof material, sealing the two hoses and completing the connection between the first hose 1 and the second hose 2. The movement of the connecting ring 33 and the pushing of the limiting ring 35 to the outside of the limiting ring 36 bring the limiting block 38 into the limiting groove 37. Then, the limiting ring 35 is rotated to move the limiting block 38 to the other side of the limiting groove 37, and the spring 32 locks the positioning pin 39 into the limiting ring 36. This completes the connection between hose 1 and hose 2, thereby enabling a quick connection between hose 1 and hose 2 and improving the efficiency of workers in connecting hose 1 and hose 2.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
