Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

referring to fig. 1 and 2, for the utility model discloses a toilet bowl inlet tube convenient to observe, include along the first joint 1 that the direction of intaking connects in order, weave hose 2, rotating-tube 3, transparent hose 4 and second joint 5. Wherein, the rotating pipe 3 is fixedly connected with the braided hose 2 through a flange, and the transparent hose 4 is a PVC steel wire hose. In addition, an annular gap is reserved between the end parts of the rotating pipe 3 and the transparent hose 4, the end part of the rotating pipe 3 extends outwards and forms a flange 31 which is abutted to the circumferential inner wall of the transparent hose 4 and seals the annular gap, and the rotating pipe 3 is rotatably connected to the transparent hose 4 through a rotating seal assembly 6 arranged in the annular gap.

Referring to fig. 2, in particular, the rotary seal assembly 6 includes a retainer ring 61, a retainer ring 62, an elastic member 63, a spring seat 64, a ferrule 65, a rubber support 66, a movable ring 67, and a stationary ring 68, which are arranged in sequence in the axial direction. The rubber mount 66 includes an axial connecting portion 661, an abutting portion 662, and a neck portion 663 connecting the axial connecting portion 661 and the abutting portion 662, so that the rubber mount 66 is in a zigzag shape. The transparent hose 4 is tightly sleeved on the retainer ring 62 and the stationary ring 68, and the retainer ring 61 and the coupling portion 661 are tightly sleeved on the rotating pipe 3. The axial end faces of the retainer ring 62 and the retainer ring 61 abut against each other, and the axial end faces of the movable ring 67 and the stationary ring 68 abut against each other.

The ferrule 65 is fitted over the coupling portion 661, and the spring retainer 64 is fitted over the ferrule 65 and the movable ring 67 and abuts against the circumferential outer wall and the axial side wall of the abutting portion 662. The elastic member 63 is a spring, and is sleeved outside the spring seat 64, and two ends of the elastic member axially abut against the retainer ring 62 and the spring seat 64, respectively. When the rubber support 66 rotates along with the rotating tube 3, the passing water flow can enable the rotating tube 3 to vibrate slightly, the shaft connecting part 661 tightly sleeved on the rotating tube 3 can provide compensation through pre-deformation, and the neck part 663 can rotate slightly relative to the rotating tube 3 in a tangential direction to the axis, so that the abutting part 662 can keep abutting against the spring seat 64 and the movable ring 67, and the sealing performance can be effectively guaranteed while the vibration is compensated between the shafts.

After the rotary seal assembly 6 is installed, the elastic member 63 provides pre-pressure, so that multiple sealing surfaces are formed between the baffle ring 61 and the baffle ring 62, between the rubber support 66 and the movable ring 67, and between the movable ring 67 and the fixed ring 68 in the axial direction, and multiple sealing surfaces are formed between the baffle ring 61 and the rotary tube 3, between the baffle ring 62 and the transparent hose 4, between the spring seat 64 and the ferrule 65, between the spring seat 64 and the movable ring 67, between the ferrule 65 and the rubber support 66, between the rubber support 66 and the rotary tube 3, and between the fixed ring 68 and the transparent hose 4 in the radial direction, so that a good pre-sealing effect is achieved, and water leakage in an annular gap can be avoided while relative rotation between the rotary tube 3 and the transparent hose 4 is not influenced.

In addition, the outer wall of the fixed ring 68 in the circumferential direction is provided with a side sealing groove 681, a sealing ring 69 abutting against the inner wall of the transparent hose 4 is embedded in the side sealing groove 681, and the cross section of the sealing ring 69 is circular or elliptical, preferably circular. The cambered surface that the surface formed outside sealing washer 69 is convenient for the cover of transparent hose 4 to establish, and can change into face contact because of contradicting between transparent hose 4 after establishing and sealing washer 69, further improve sealing performance.

The end of the rubber holder 66 is provided with a stopper 664 projecting in the radial direction, and the stopper 664 covers the axial end surface of the ferrule 65 to restrict the ferrule 65 from easily coming off the rubber holder 66.

The implementation principle of the embodiment is as follows: in actual installation, the second joint 5 is connected with a water inlet valve of a water tank of the toilet, and the first joint 1 is connected with other water inlet pipelines. When the toilet bowl water tank intake, its water intake state can directly observe through transparent hose 4, is convenient for in time feed back the water intake state of water tank to judge the running state of water tank. And transparent hose 4 and weave the mode that carries out the rotation connection through rotating tube 3 and rotation seal assembly 6 between the hose 2, not only make the rotation state between first joint 1 and the second joint 5 mutual noninterference, can guarantee the leakproofness of inlet tube again, the installation of the inlet tube of being convenient for is used.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
