Abstract
Description
Technical Field
[0001] This application relates to the field of water dispenser technology, and more specifically, to a leak-proof protection device for the external interface of a water dispenser. Background Technology
[0002] Currently, when water dispensers use tap water as their water source, the connection point between the dispenser and the tap water pipe can become loose and leak over time due to the vibration caused by water flowing through the connection. This can damage floors, furniture, and walls, making the dispenser less practical.
[0003] To address the aforementioned issues, this application provides a leak-proof protection device for the external interface of a water dispenser. Utility Model Content
[0004] One objective of this application is to provide a leak-proof protection device for the external interface of a water dispenser, comprising a water dispenser body, a water inlet installed on the water dispenser body, a water inlet pipe installed on the outside of the water inlet, a fixing ring fixedly sleeved on the outside of the water inlet pipe, a plurality of limiting rods fixedly connected to one side of the fixing ring, a baffle fixedly connected to the end of the limiting rod away from the fixing ring, a plurality of limiting plates fixedly connected to the outside of the water inlet, a sliding ring slidably sleeved on the outside of the water inlet, a plurality of moving plates fixedly connected to the side of the sliding ring near the water inlet pipe, a limiting component provided on the sliding ring, and a limiting groove formed on the outside of the water inlet.
[0005] Furthermore, multiple sliding grooves are provided on the outer side of the water inlet, and a matching sliding block is slidably connected inside the sliding groove. The outer surface of the sliding block is fixedly connected to the inner surface of the sliding ring.
[0006] Furthermore, the limiting component includes a cavity formed inside the sliding ring, a sliding plate slidably connected inside the cavity, a limiting block fixedly connected to one side of the sliding plate, a connecting rod fixedly connected to the other side of the sliding plate, and a spring provided inside the cavity.
[0007] Furthermore, the spring is sleeved on the outside of the connecting rod, one end of the spring is fixedly connected to the sliding plate, and the other end of the spring is fixedly connected to the inner wall of the cavity.
[0008] Furthermore, the end of the limiting block away from the sliding plate extends through the inner cavity of the sliding ring to the inside of the limiting groove, the end of the connecting rod away from the sliding plate extends through the inner cavity of the sliding ring to the outside of the sliding ring, and a carrying plate is fixedly connected to the end of the connecting rod away from the sliding plate.
[0009] Furthermore, the inner wall of the water inlet is provided with a first annular groove, the inner wall of the first annular groove is provided with a second annular groove, a first annular plate adapted to the first annular groove is fixedly connected to the water inlet pipe, a second annular plate adapted to the second annular groove is fixedly connected to the outer side of the first annular plate, and a sealing ring is provided on the surface of the water inlet, the inner bottom wall of the first annular groove and the second annular groove.
[0010] The beneficial effects of this application are:
[0011] When connecting the water inlet and the water pipe, this application rotates the water pipe to rotate the limiting rod into the inside of the limiting plate, and the baffle rotates to one side of the limiting plate to limit the limiting rod, thereby driving the sliding ring to move. At this time, the spring is in a contracted state, and the movement of the sliding ring drives the limiting block and the moving plate to move. When the sliding block moves to one side of the inner wall of the sliding groove, the limiting block corresponds to the limiting groove. At this time, the spring resets and generates a thrust, and the limiting block inserts into the inside of the limiting groove to complete the limiting and fixing of the sliding ring. At this time, the moving plate moves to one side of the limiting plate, thereby blocking the limiting rod and limiting one side of the limiting rod, thus firmly connecting the water inlet and the water pipe. The application also uses two annular grooves in conjunction with two annular plates and places three sealing rings between the water inlet and the water pipe to achieve a multi-level sealing effect and improve the connection sealing between the water pipe and the water inlet.
[0012] In summary, this application features a detachable installation structure at the water inlet and water pipe of the water dispenser to securely connect the water pipe and the water inlet. This structure also provides multi-level sealing at the connection between the water inlet and the water pipe to prevent the water dispenser interface from loosening and leaking.

[0024] Example:
[0025] Please see Figure 1 , Figure 2 and Figure 3This application discloses a leak-proof protection device for the external interface of a water dispenser, including a water dispenser body 1. A water inlet 2 is installed on the water dispenser body 1. A water inlet pipe 3 is installed on the outside of the water inlet 2. A fixing ring 8 is fixedly sleeved on the outside of the water inlet pipe 3. Multiple limiting rods 12 are fixedly connected to one side of the fixing ring 8. A baffle 10 is fixedly connected to the end of the limiting rod 12 away from the fixing ring 8. Multiple limiting plates 9 are fixedly connected to the outside of the water inlet 2. A sliding ring 4 is slidably sleeved on the outside of the water inlet 2. Multiple sliding grooves 5 are formed on the outside of the water inlet 2. A sliding connection is slidably made inside the sliding grooves 5. The sliding block 6 and sliding groove 5 are matched to limit the sliding of the sliding ring 4, preventing the sliding ring 4 from rotating outside the water inlet 2. The outer surface of the sliding block 6 is fixedly connected to the inner surface of the sliding ring 4. Multiple movable plates 7 are fixedly connected to the side of the sliding ring 4 near the water inlet 3. The water inlet 3 is inserted into the water inlet 2 and rotated to rotate the limiting rod 12 into the inside of the limiting plate 9. The baffle 10 is rotated to one side of the limiting plate 9 to limit the limiting rod 12. A limiting component is provided on the sliding ring 4 and a limiting groove 14 is opened on the outside of the water inlet 2.
[0026] Please see Figure 4 The limiting component includes a cavity 18 formed inside the sliding ring 4. A sliding plate 16 is slidably connected inside the cavity 18. A limiting block 15 is fixedly connected to one side of the sliding plate 16, and a connecting rod 13 is fixedly connected to the other side of the sliding plate 16. A spring 17 is provided inside the cavity 18. The spring 17 is sleeved on the outside of the connecting rod 13. One end of the spring 17 is fixedly connected to the sliding plate 16, and the other end of the spring 17 is fixedly connected to the inner wall of the cavity 18. The end of the limiting block 15 away from the sliding plate 16 extends through the inner cavity of the sliding ring 4 to the inside of the limiting groove 14. The end of the connecting rod 13 away from the sliding plate 16 extends through the inner cavity of the sliding ring 4 to the outside of the sliding ring 4.
[0027] A handle 11 is fixedly connected to the end of the connecting rod 13 away from the sliding plate 16, which drives the sliding ring 4 to move. At this time, the spring 17 is in a contracted state. The movement of the sliding ring 4 drives the limiting block 15 and the moving plate 7 to move. When the sliding block 6 moves to one side of the inner wall of the sliding groove 5, the limiting block 15 corresponds to the limiting groove 14. At this time, the spring 17 resets and generates a thrust. The sliding plate 16 moves to its original position, and the limiting block 15 is inserted into the inside of the limiting groove 14. In this way, the limiting block 15 is inserted into the inside of the limiting groove 14, thus completing the limiting and fixing of the sliding ring 4, thereby realizing the limiting of the four moving plates 7. At this time, the moving plate 7 moves to one side of the limiting plate 9, thereby blocking the limiting rod 12 and realizing the limiting of one side of the limiting rod 12.
[0028] Please see Figure 3 and Figure 4The inner wall of the water inlet 2 has a first annular groove, and the inner wall of the first annular groove has a second annular groove. A first annular plate that matches the first annular groove is fixedly connected to the water pipe 3. A second annular plate that matches the second annular groove is fixedly connected to the outer side of the first annular plate. Sealing rings are provided on the surface of the water inlet 2 and the inner bottom walls of the first and second annular grooves. When the water pipe 3 is inserted into the water inlet 2, the first annular plate is inserted into the first annular groove, and the second annular plate is inserted into the second annular groove. The two annular grooves work together with the two annular plates, and the three sealing rings are set on the water inlet 2 and the water pipe 3 to achieve a multi-level sealing effect, thereby improving the connection sealing between the water pipe 3 and the water inlet 2.
[0029] The implementation principle of this application embodiment is as follows: the water inlet pipe 3 is inserted into the water outlet 2, the first annular plate is inserted into the first annular groove, and the second annular plate is inserted into the second annular groove. In this way, the two annular grooves work together with the two annular plates, and three sealing rings are placed between the water outlet 2 and the water inlet pipe 3, thereby achieving a multi-level sealing effect and improving the connection sealing between the water inlet pipe 3 and the water outlet 2.
[0030] Then rotate the water inlet pipe 3, rotating the limiting rod 12 into the inside of the limiting plate 9. The baffle 10 rotates to one side of the limiting plate 9, forming a limit on the limiting rod 12, driving the sliding ring 4 to move. At this time, the spring 17 is in a contracted state. The movement of the sliding ring 4 drives the limiting block 15 and the moving plate 7 to move. When the sliding block 6 moves to one side of the inner wall of the sliding groove 5, the limiting block 15 corresponds to the limiting groove 14. At this time, the spring 17 resets and generates a thrust. The sliding plate 16 moves to its original position, and the limiting block 15 is inserted into the inside of the limiting groove 14. In this way, the limiting block 15 is inserted into the inside of the limiting groove 14, completing the limiting and fixing of the sliding ring 4. At this time, the moving plate 7 moves to one side of the limiting plate 9, thereby blocking the limiting rod 12 and limiting one side of the limiting rod 12, thus firmly connecting the water inlet 2 and the water inlet pipe 3, preventing the interface from loosening and causing leakage.
[0031] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and application concept of this application, should be included within the scope of protection of this application.
