[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1
[0026] Existing water dispenser valves are prone to breakage at the handle due to excessive force during use. Replacing them with new valves is overly complicated, thus affecting the normal operation of the water dispenser. Please refer to... Figures 1-5 This embodiment provides an installation structure for a drain valve, solving the technical problem of cumbersome drain valve replacement. The device includes a connecting pipe 1 serving as a supporting base, a docking limiting component 2 for limiting the drain valve, and a limiting release component 3 for limiting the drain valve by contacting the docking limiting component 2. The docking limiting component 2 enables the drain valve to dock with the connecting pipe 1, and the limiting release component 3 releases the limiting effect of the docking limiting component 2.
[0027] The existing water dispenser's drain valve may break or be damaged at the switch wrench due to excessive force during use. However, replacing the drain valve with a new one is too cumbersome, thus affecting the normal use of the water dispenser. In order to solve this problem, the docking limit component 2 is proposed. The docking limiting assembly 2 includes a docking threaded tube 21 fixedly connected to the end of the docking tube 1. A limiting threaded groove 22 is opened at the end of the docking tube 1 away from the docking threaded tube 21. A fitting groove 23 is opened on the inner side of the docking tube 1. A buffer groove 24 is opened on the inner side of the docking tube 1 away from the fitting groove 23. A plurality of locking limiting grooves 25 are opened at equal intervals on the inner side of the docking tube 1 away from the buffer groove 24. A sealing gasket 26 is fixedly connected to the fitting groove 23 near the pipe wall of the docking tube 1. A spring-loaded support frame 27 is fixedly connected to the inner side of the buffer groove 24. A limiting return bend 28 is fixedly connected to the end of the spring-loaded support frame 27. A plurality of limiting anti-slip patterns 29 are fixedly connected to the outer side of the end of the docking tube 1 near the fitting groove 23. An inclined groove is opened on the inner side of the spring-loaded support frame 27, and the end of the spring-loaded support frame 27 is fitted with the limiting anti-slip pattern 29. A water outlet pipe 4 is slidably connected to the inner side of the docking tube 1. The fitting groove 23 is fitted with the end of the water outlet pipe 4. By inserting the water outlet pipe 4 into the inner side of the connecting pipe 1, the end of the water outlet pipe 4 will be embedded in the fitting groove 23. During this time, the rebound support frame 27 inside the buffer groove 24 will support the limiting bending piece 28 and abut against the middle of the limiting anti-slip texture 29 on the outer side of the end of the water outlet pipe 4, thereby achieving the limiting.
[0028] Example 2
[0029] Based on Example 1, Example 1 solved the technical problem of the cumbersome process of replacing the drain valve, but it still has the problem of complex limiting contact process of the docking limiting component 2. Figures 1-5As shown, the specific implementation process is as follows: In actual use, the contact and limiting process of the docking limit component 2 is very cumbersome. In order to solve this problem, the limit release component 3 is proposed. The limit release component 3 includes a limit tube 31 set on the outside of the docking pipe 1. Several connecting brackets 32 are fixedly connected at equal intervals on one side of the inside of the limit tube 31. A docking ring 33 is set on the inside of the limit tube 31. A connecting groove 34 is opened on the outside of the docking ring 33, which is slidably connected to the several connecting brackets 32. Several docking slides 35 are fixedly connected at equal intervals on the end of the docking ring 33 near the limit tube 31. An abutting slide 36 is fixedly connected on the end of the docking slide 35 away from the docking ring 33. A water outlet valve 5 is installed in the middle section of the water outlet pipe 4. A sealing rubber ring 6 is placed inside the fitting groove 23. The docking screw tube 21 is spirally connected to the limit tube 31. The abutting slide 36 is fitted into the inclined groove opened on the rebound support frame 27. The limiting tube 31 is spirally connected to the outside of the connecting tube 1. As the limiting tube 31 rotates, the connecting bracket 32 connected to it will rotate inside the connecting groove 34 opened on the outside of the connecting ring 33, and drive the connecting ring 33 to move. This will drive the connecting slide 35 and the abutting slide 36 connected to it to move until the abutting slide 36 is inserted into the limiting return bend 28. This will drive the limiting return bend 28 to straighten, so that the limiting return bend 28 loses its limitation with the limiting anti-slip texture 29, and the limiting tube 31 can be pulled out.
