An adjustment structure suitable for the floating barrel of the water inlet valve of the toilet water tank

Abstract

The invention relates to an adjustment structure suitable for a toilet water tank inlet valve floating bucket. The adjustment structure comprises an inlet valve capable of being arranged in a toilet water tank, wherein the floating bucket is arranged on a water inlet pipe of the inlet valve in a sleeved mode, and a toothed groove with the arc length being 3 / 4 of the circumference is annularly arranged on the outer wall of the water inlet pipe. The floating bucket comprises a sleeve ring capable of being arranged on the water inlet pipe in a sleeved mode, a floating barrel is arranged on one side of the sleeve ring, an upper axle hole and a lower axle hole which are coaxial are convexly formed in one side, along the circle center line, of the inner wall of the sleeve ring, a groove is dug between the two axle holes, a pulling shank is provided with a handle, a cam is arranged on one side of the handle and provided with an eccentric circular shaft, the pulling shank is connected with the axle holes through the circular shaft and arranged in the groove, the wheel face of the cam is in contact with the outer wall face of the water inlet pipe, a clamping tongue is convexly arranged on the other side, along the circle center line, of the inner wall of the sleeve ring, two elastic pieces are symmetrically arranged on the two sides of the clamping tongue, the elastic pieces are in contact with the toothed face of the toothed groove, and the clamping tongue can be inserted in the toothed groove. The adjustment structure can achieve comprehensive adjustment by moving up and down and rotating around the shaft, and can be conveniently operated in a narrow space of the water tank.

Description

technical field [0001] The invention belongs to the field of matching valve fittings for water tanks, and in particular relates to an adjustment structure suitable for a floating barrel of a water inlet valve of a toilet water tank. Background technique [0002] The main function of the water inlet device of the toilet water tank is to automatically provide the water tank with an accurate amount of water. The purpose of the floating bucket is to adjust the working water level in the water tank when the water inlet valve automatically stops the water. At present, most of the structures used to adjust the structure of the floating bucket in the water tank on the market are to push the block into the gap between the teeth by plugging or rotating to lock it. For example, the Patent Office Publication No. CN2355009Y is called "Sanitary Ware Water Tank Floating Bucket Type Water Inlet Valve". When adjusting the water level, four clips are evenly distributed on the outer surface of...

AI Technical Summary

Problems solved by technology

[0003] Above these prior art structures, along with technological progress and design based on water-saving functions, the space inside the toilet tank becomes narrower, and the water inlet valve is usually contained on the corner position of the water tank, the first, adjust the floating bucket to loosen and When locking, it is not only necessary to accurately find the point of force, but also requires a lot of effort, which is difficult to operate in practice; second, the floating bucket can only be adjusted by moving up and down, and cannot realize the adjustment of rotating and swinging around the inlet pipe, which is not conducive to installation and use
