Description

Technical Field

[0001] The utility model relates to the technical field of toilet water tanks, in particular to a toilet water tank lever. Background Art

[0002] With the improvement of modern living standards, toilets, as essential sanitary fixtures in homes and public spaces, are receiving increasing attention for their functionality and design. One of the core components of a toilet is the water tank system, which is responsible for storing and releasing water for flushing. Within the water tank system, the lever is a key component that the user directly operates. It mechanically pulls the drain valve to release water. Therefore, the design of the lever not only affects the proper use of the toilet but also directly impacts the user experience and the durability of the entire system.

[0003] Traditional toilet tank levers have a simple structure, typically relying solely on basic mechanical connections to transmit operating force. This simple design often meets basic flushing needs in the early stages of use. However, over time, due to frequent operation or exposure to humidity, the lever components can become loose, worn, or corroded. These issues not only reduce operational feel and affect flushing effectiveness, but can also lead to a range of problems, including tank leaks and operational failures, increasing maintenance costs and user dissatisfaction.

[0030] Example

[0031] See also Figure 1-6 The utility model provides a technical solution: a toilet water tank lever, comprising a water tank lever 1, a steering block 9 and a pull rod 11, a fixing rod 2 is inserted into the interior of the water tank lever 1, a tightening screw 4 is inserted into the surface of the fixing rod 2, a No. 1 through-hole 14 is opened inside the tightening screw 4, and the tightening screw 4 is sleeved on the surface of the fixing rod 2 through the No. 1 through-hole 14, ensuring a close fit between the tightening screw 4 and the fixing rod 2, reducing the risk of loosening, making it easier to fit the tightening screw 4 on the fixing rod 2, simplifying the installation process, and improving maintenance. The spring 3 is located at the pressing part between the fixing rod 2 and the tightening screw 4. The spring 3 allows the water tank lever 1 to automatically return to its initial position after the operation is completed, thereby improving the convenience and smoothness of use. The surface of the tightening screw 4 is threadedly connected with a tightening nut 6. A silicone gasket 5 is installed between the tightening nut 6 and the tightening screw 4. The silicone gasket 5 can absorb vibration, avoid loosening between parts, and improve the stability of the connection. A spline groove 17 and a through hole 18 are respectively provided at both ends of the steering block 9. The rod 11 is fixedly connected to the through hole 18 of the steering block 9 by a fixing screw 10. A spline block 16 is fixedly installed on the surface of the fixing rod 2. The spline block 16 is inserted into the inside of the spline groove 17. A second through hole 15 is opened inside the fixing rod 2. A flat-type long screw 8 is inserted into the inside of the second through hole 15. An open gasket 7 is provided between the tightening screw 4 and the steering block 9, and the open gasket 7 is sleeved on the surface of the fixing rod 2 to reduce the friction between the tightening screw 4 and the steering block 9 and extend the service life of the parts. In addition, the use of a flat-type long screw The long screw 8 is more flexible in tightening the screw 4, the fixing rod 2 and the steering block 9, which is convenient for the operator to adjust the tightness of the lever. A groove 12 is provided inside the water tank lever 1, and a screw hole 13 is provided inside the groove 12. The flat-head screw 8 is threadedly connected inside the screw hole 13. The shape of the end of the fixing rod 2 matches the shape of the groove 12, and the end of the fixing rod 2 is inserted into the inside of the groove 12, which ensures the stability of the fixing rod 2 in the groove 12, is not easy to be displaced, and improves the accuracy of assembly.

[0032] Working principle: When the user pulls the water tank lever 1, the external mechanical force is transmitted to the internal pull rod 11 and steering block 9 through the lever. A spline groove 17 is provided at one end of the steering block 9, which meshes with the spline block 16 on the surface of the fixed rod 2, ensuring that the steering block 9 maintains precise matching with the fixed rod 2 during rotation, avoiding slipping or misalignment during rotation, thereby ensuring the stability of the water tank lever 1. As the steering block 9 rotates, the pull rod 11 will also move and pull the drain valve to complete the drainage operation. The pull rod 11 and the steering block 9 are connected by a fixing screw 10, ensuring effective force transmission and avoiding displacement or loosening during use. The water tank lever 1 structure uses a tightening screw 4 to cooperate with a compression nut 6, which not only enhances the overall stability of the lever, but also absorbs vibrations during operation through the surface-mounted silicone gasket 5 to avoid looseness between components, and an open gasket 7 is installed between the tightening screw 4 and the steering block 9, which can reduce the friction between the tightening screw 4 and the steering block 9, ensuring smooth operation of the lever during use, while also reducing wear between components and extending the service life of the water tank lever 1. A group of springs 3 are installed at the press-fit between the fixing rod 2 and the tightening screw 4. The spring 3 can not only automatically reset the lever after the operation is completed, but also provide additional buffering force during operation to reduce the wear of components caused by impact. Through the elastic force of the spring 3, the lever can quickly and accurately return to its initial position, providing users with a smooth and natural use experience. The fixing rod 2 and the lever are also reinforced by screw holes 13 and a flat-length screw 8 to ensure a close connection between the components. When necessary, the operator can fine-tune the tightness of the lever by adjusting the flat-length screw 8 to adapt to different usage needs and maintenance requirements.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
