Description

Variable-pitch joint with filtering function

Technical Field

The utility model relates to a displacement joint field for connecting cold and hot inlet tube and cold and hot tap especially relates to a take filtering capability's displacement to connect.

Background

In the current bathroom trade, because the inlet tube centre-to-centre spacing in each occasion wall body exists the difference, for simple to operate, universal shower faucet intakes the end and all can use the displacement to connect, and the effect that current displacement connects only has simple displacement function. In the process of using the shower faucet, the condition that a faucet assembly is damaged or the interior of the faucet is blocked and needs to be maintained may exist, in order to maintain the faucet conveniently, an angle valve is generally required to be installed on a water path at the water inlet front end of the faucet to serve as a switch valve of the water path, and a filtering device is required to be installed to filter impurities in water, so that the user cost is directly increased, installation steps are complex, and construction difficulty and time consumption are improved;

the 201620814269.8 patent solves the problem well, but it is somewhat cumbersome to remove the filter unit by shutting off the water feed first.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a take filtering capability's displacement to connect, it can intake by self-closing when wasing filter equipment, and does not need specialized tool.

In order to realize the above purpose, the utility model provides a take filtering capability's displacement to connect for cold and hot inlet tube and cold and hot tap's being connected, its characterized in that: a be connected for cold and hot inlet tube and cold and hot tap, its characterized in that: the filter comprises a main body, a fixed cylinder, a filter cylinder, a water sealing shaft, a filter screen, a first sealing ring, a second sealing ring and a third sealing ring;

the main body is provided with a water inlet, a water outlet, a first sealing position, a second sealing position, a first internal thread and a second internal thread, the fixed cylinder is provided with a first sealing groove, a first external thread, a third internal thread, a water through groove and a water through opening, the filter cylinder is provided with a filter frame, a second external thread, a second sealing groove, a transmission groove and a rotating groove, and the water sealing shaft is provided with a third external thread, a third sealing groove and a transmission part; wherein the second internal thread, the second external thread, the third internal thread and the third external thread have the same pitch;

the first seal ring is in the first seal groove, the second seal ring is in the second seal groove, and the third seal ring is in the third seal groove; the third male thread is in the third female thread with the third seal ring in the third seal groove in the water passage port; the first external thread is in the first internal thread with the first seal ring in the first seal groove in the first seal position; the filter screen is sleeved on the filter frame, the second external thread is arranged at the outer end of the second internal thread, and the transmission part is arranged in the transmission groove;

the rotating groove is rotated, the filter cartridge drives the water sealing shaft to rotate, so that the second sealing ring in the second sealing groove moves to the second sealing position, the third sealing ring in the third sealing groove leaves the water through opening, and the water through opening is opened.

The utility model has the advantages that: simple structure and convenient cleaning of the filter screen.
