Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to a water inlet valve locking device. Background Technology

[0002] Because toilet tanks come in a wide variety of types and sizes, inlet valves are typically height-adjustable to accommodate different tanks. Existing inlet valve adjustment mechanisms include an inlet body, an inlet pipe fitted onto the inlet body, and a retaining ring at the junction of the inlet body and the inlet pipe. The height of the inlet valve is adjusted by regulating the length of the inlet pipe extending into the inlet body. The bottom of the inlet body has multiple elastic sections along its circumference. During installation, the retaining ring is first moved upwards along the inlet body to allow the inlet pipe to fit inside. Once the inlet pipe is adjusted to the desired position, the retaining ring is moved downwards to tighten the elastic sections inwards, thus limiting the inlet pipe's axial movement. However, during use, when the water pressure on the inlet body is high, the retaining ring may move axially with the inlet body, causing the inlet body to detach from the inlet pipe, posing a significant safety hazard. Utility Model Content

[0003] This utility model discloses a water inlet valve locking device, which aims to improve the problem that the existing water inlet valve adjustment structure is prone to loosening.

[0004] The present invention adopts the following solution: A water inlet valve locking device includes an inlet body, an adjusting pipe, a retaining ring, and a buckle.

The adjusting pipe is inserted into the mounting hole formed by each of the elastic parts and is threadedly connected to the inner wall of the elastic part. The retaining ring is sleeved on the inlet body to drive each of the elastic parts to clamp towards the adjusting pipe. The buckle is adapted to the retaining ring and is inserted into or locked on the limiting part so that the retaining ring is axially limited, thereby locking the inlet body and the adjusting pipe.

[0005] As a further improvement, the outer wall of the buckle is provided with an assembly groove communicating with its inner wall, the buckle is inserted into the assembly groove, and has a locking part for engaging with the limiting part.

[0006] As a further improvement, the limiting part is a groove recessed along the outer wall of the elastic part, and the locking part is inserted into the groove so that the buckle is axially limited.

[0007] As a further improvement, the assembly slot is provided with a first guide portion, and the buckle is provided with a second guide portion for adapting to the first guide portion, so that the buckle can move along the first guide portion.

[0008] As a further improvement, the buckle has a handle position that is positioned above the top of the mounting slot.

[0009] As a further improvement, the locking part is located in the middle of the buckle, the buckle has hook parts on both sides, and the side wall of the assembly groove has a positioning groove for matching the hook parts.

[0010] As a further improvement, an assembly groove is provided vertically along the outer wall of the buckle, and the buckle is inserted into the assembly groove, and has a locking part for engaging with the limiting part.

[0021] Combination Figures 1 to 10 This embodiment provides a water inlet valve locking device, including a water inlet body 1, an adjusting pipe 2, a retaining ring 3, and a buckle 4. The bottom of the water inlet body 1 is provided with a plurality of elastic parts 11 along the circumferential direction, and at least one of the elastic parts 11 has a limiting part 111 formed on its side wall. The adjusting pipe 2 is inserted into the mounting hole 12 formed by each elastic part 11 and is threadedly connected to the inner wall of the elastic part 11. The retaining ring 3 is sleeved on the water inlet body 1 to drive each elastic part 11 to hug towards the adjusting pipe 2. The buckle 4 is adapted to the retaining ring 3 and is inserted or locked on the limiting part 111 so that the retaining ring 3 is axially limited, thereby locking the water inlet body 1 and the adjusting pipe 2.

[0022] It should be noted that in this embodiment, by providing a limiting part 111 on the elastic part 11 and a buckle 4 for connecting with the limiting part 111 on the buckle 3, the buckle 3 is axially limited, ensuring the clamping force of the elastic part 11, thus locking the water inlet body 1 and the regulating pipe 2. This prevents the water inlet body 1 from loosening from the regulating pipe 2 under water pressure, thereby improving the safety and stability of the product. Simultaneously, the buckle 4 ensures reliable connection of the water inlet valve during transportation, preventing parts from being lost. During installation, first move the retaining ring 3 upwards along the inlet body 1. At this time, the elastic part 11 opens outwards to allow the adjusting tube 2 to be inserted into the mounting hole 12. After adjusting to the desired height, move the retaining ring 3 downwards along the inlet body 1. At this time, the elastic part 11, under the action of the retaining ring 3, grips the adjusting tube 2 inwards, so that the external thread 21 on the adjusting tube 2 is screwed into the internal thread 121 on the inner wall of the elastic part 11. Then connect the buckle 4 to the limiting part 111 to lock the adjusting tube 2 to the inlet body 1, ensuring the firmness and safety of the inlet valve connection. In addition, the threaded connection between the elastic part 11 and the adjusting tube 2 allows for stepless adjustment of the inlet valve height, enabling the inlet valve to be compatible with more types of toilet tanks.

[0023] In a preferred embodiment, the outer wall of the buckle 3 is provided with a mounting groove 31 communicating with its inner wall. The buckle 4 is inserted into the mounting groove 31 and has a locking part 41 for engaging with the limiting part 111. For example, the mounting groove 31 is configured to extend laterally through the side wall of the buckle 3, the limiting part 111 is a groove recessed along the outer wall of the elastic part 11, and the locking part 41 is inserted into the groove to limit the buckle 3 axially. During installation, the buckle 4 is inserted into the mounting groove 31 and the locking part 41 is inserted into the groove.

[0024] In one embodiment, a locking part 41 is located in the middle of the buckle 4, and hook parts 42 are provided on both sides of the buckle 4. A positioning groove 311 is provided on the side wall of the mounting groove 31 to fit the hook parts 42. During installation, the hook parts 42 engage with the positioning groove 311 to limit the buckle 4, while the locking part 41 extends into the groove to limit the buckle 3 axially. Preferably, two positioning grooves 311 are provided, one for locking and one for unlocking, to prevent the buckle 4 from being lost.

[0025] Furthermore, the assembly groove 31 is provided with a first guide portion 312, and the buckle 4 is provided with a second guide portion 43 for matching the first guide portion 312, so that the buckle 4 can move along the first guide portion 312, ensuring that the buckle 4 moves smoothly in the assembly groove 31 and preventing the buckle 4 from shifting.

[0026] In other embodiments, the buckle 4 has a handle position 44, which is positioned above the top of the mounting groove 31. Users or operators can pull the buckle 4 through the handle position 44 to engage or disengage the locking portion 41 from the groove, facilitating unlocking and locking operations.

[0027] Reference Figures 11 to 17 In another embodiment, an assembly groove 31 is vertically provided along the outer wall of the buckle 3, and the buckle 4 is inserted into the assembly groove 31. The buckle 4 has a locking part 41 for engaging with the limiting part 111. The buckle 4 and the assembly groove 31 can be fixed by adhesive or welding. For example, the outer wall of the elastic part 11 has a protruding limiting part 111 arranged horizontally, and the locking part 41 engages with the limiting part 111 for limiting. The limiting part 111 is located at the bottom of the elastic part 11. When the buckle 3 is pushed downwards, the elastic part 11 tightens inwards, and simultaneously the locking part 41 on the buckle 4 engages with the limiting part 111 for limiting, thus keeping the elastic part 11 in a tightened state and locking the water inlet body 1 and the regulating pipe 2. Operation is convenient; when the height of the water inlet valve needs to be adjusted, simply pull the buckle 3 upwards to disengage the locking part 41 from the limiting part 111. The locking part 41 is preferably an elastic hook, but it is not limited thereto and is not specifically limited thereto.

[0028] Based on the above embodiments, in an optional embodiment of this utility model, the inner wall of the buckle 3 is provided with a guide rail 32 or a guide groove 33, and the water inlet body 1 is provided with a positioning part 13 that engages with the guide rail 32 or the guide groove 33, so that the buckle 3 is limited in the circumferential direction, ensuring that the buckle 4 on the buckle 3 can be aligned with the limiting part 111, so that the engagement is smooth. It should be noted that in this embodiment, both the buckle 3 and the buckle 4 are plastic parts, which are small and simple in structure. This saves material costs and also saves labor assembly costs. The method of using the buckle 4 to engage with the limiting part 111 allows for quick operation, and users can accurately lock and unlock the buckle based on common sense, making it less likely to mis-install.

[0029] Reference Figures 18 to 23 In other embodiments, an assembly groove 31 is provided laterally along the outer wall of the buckle 3, and a limiting part 111 is provided on the outer wall of the elastic part 11, which is arranged vertically. The buckle 4 is inserted into the assembly groove 31, and its locking part 41 engages with the limiting part 111 for limiting. During installation, the buckle 3 is moved downward so that the buckle 4 located in the assembly groove 31 moves downward synchronously. After the buckle 3 is moved into place, the buckle 3 is rotated so that the locking part 41 engages with the limiting part 111 for limiting. For example, the limiting part 111 is a rib that protrudes along the outer wall of the elastic part 11, and the locking part 41 is an elastic hook. The elastic hook is locked on the rib so that the buckle 3 is limited axially. When the height of the inlet valve needs to be readjusted, rotate the retaining ring 3 in the direction that the retaining part 41 is disengaged from the limiting part 111 so that the retaining part 41 is disengaged from the limiting part 111. Then push the retaining ring 3 upward so that the elastic part 11 opens outward, thereby facilitating the adjustment of the length of the regulating pipe 2.
