Height adjusting device for water inlet valve

Abstract

The invention discloses a height adjusting device for a water inlet valve. The device comprises a water inlet pipe, a water inlet valve body, a rotary clamping ring and a lifting rod, a pipe opening is formed in the bottom of the water inlet valve body, the water inlet pipe can penetrate through the pipe opening, and the rotary clamping ring is arranged on the inner circumference of the pipe opening; the inner wall of the rotary clamping ring is provided with at least one longitudinal column of transverse inner teeth arranged at intervals, the periphery of the water inlet pipe is provided with at least one longitudinal column of transverse outer teeth arranged at intervals and at least one longitudinal column of receding channels, the transverse outer teeth are meshed and matched with the transverse inner teeth, the receding channels are located beside the transverse outer teeth, and the receding channels allow the transverse inner teeth to move up and down; and the outer wall of the rotary clamping ring is provided with a longitudinally-inclined sliding groove, a sliding block is arranged in the sliding groove in a sliding mode, the sliding block is formed at the bottom of the lifting rod, the lifting rod is installed on the water inlet valve body in a sliding mode, and the top of the lifting rod extends out of the water inlet valve body. According to the scheme, height adjustment is more convenient during use, the structure is simpler and more compact, and user operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of water inlet valves, in particular to a height adjusting device for water inlet valves. Background technique [0002] The water storage capacity of the water tank can be controlled by controlling the height of the water inlet valve. Because the structure of the traditional water inlet valve is relatively fine and complex, the work of adjusting the height of the water inlet valve is usually performed by professionals, which is inconvenient for users and increases living expenses virtually. At present, there are mainly plug-type water inlet valve height adjustment devices on the market. Although the structure is greatly simplified compared with the traditional structure, it is still not convenient for users to ensure that the pin is inserted precisely at the card point to fix the height. Contents of the invention [0003] The object of the present invention is to provide a water inlet valve height adjustm...
