Abstract

The present invention relates to a device capable of utilizing rotary frictional force of ceramic plate to implement time delay. Said device can be used in the work required fro time delay. It is characterized by that said invention can utilize rotary frictional force produced between plane of ceramic moving plate and plate of ceramic static plate by means of atmospherical pressure to implement time delay, and its time delay is stable, and its service life is long.

Description

Utilize ceramic wafer rotary friction to realize the device of time-delay

Technical field

The present invention needing to be used for the mechanism of delay working.

Background technique

Traditional automatic delay function water tap mostly adopts rubber piston formula time-delay method, and delay function lost efficacy easily.The present invention seeks to: utilize atmospheric pressure that ceramic moving plate (hereinafter to be referred as moving plate) and ceramic still (hereinafter to be referred as still) are compressed, when moving plate rotates, produce spin friction power between moving plate and the still and realize time-delay, have the characteristics stable, the life-span long (more than 100,000 times) of delaying time, not only can be used for the automatic delay function water tap, needing in other mechanism of delay working also to can be used for.

Summary of the invention

The present invention is achieved in that the front of circular still is the plane that polishes on request, polishes, and circle centre position has a via hole, in order to by rotating shaft, a groove is arranged on the circumference, in order to still is positioned on the device.Circular moving plate front also is the plane that polishes, polishes, and circle centre position has a through hole, in order to by rotating shaft, at the moving plate reverse side, through hole is surrounded by a cylindrical wall less than the moving plate diameter, and an end of wall has two grooves along diametric(al), pin is by rotating shaft and fall in the groove, so that moving plate and rotating shaft interlock.Open one 90 ° of fan grooves along the moving plate circumference, in order to control moving plate corner.One torsion spring set is arranged outside wall, the one head is stuck on the moving plate, and the other end is stuck on the crust of the device, in order to hold power, stirs moving plate and rotates.Rotating shaft one end is outside moving plate, still, device bottom outlet extending apparatus, and this end has a groove, the axle head of water tap is made flat embed in it, so that the axle interlock of rotating shaft and water tap, the rotating shaft the other end outside the extending apparatus of top cover hole, in order to stressed, top cover with the device between with being threaded.When external force made rotating shaft rotate 90 °, the axle and the moving plate that drive water tap also rotated 90 °, and water tap is opened, and torsion spring holds power simultaneously.After external force is cancelled, torsion spring holds power and discharges, stir the moving plate backward rotation, because the effect of the spin friction power that atmospheric pressure produces between the positive and still front moving plate, torsion spring holds power and can only slowly discharge, the axle that makes moving plate, rotating shaft, water tap is backward rotation slowly, the water tap time-delay closing, and device returns original state.

Embodiment

Describe working principle of the present invention and working condition in detail below in conjunction with accompanying drawing.

The front 2 of still 1 polishes, polishes (in technology and the traditional ceramics sheet seal tap used ceramic plate technology identical), and there is via hole 3 at the center, so that rotating shaft 5 is passed through, locating slot 4 is stuck on the rib 6 of crust of the device 15, and still 1 is positioned.The front 2 of moving plate 7 also polishes, polishes, and circle centre position has a through hole 9, and in order to by rotating shaft 5, pin 10 runs through rotating shaft 5 and drops in the groove 11 of wall 8, makes moving plate 7 and rotating shaft 5 interlocks, opens one 90 ° of fan grooves 12 along moving plate 7 circumference, with control moving plate 7 corners.18 1 of torsion springs are stuck on the moving plate 7, and the other end is stuck on the crust of the device 15.The front 2 of moving plate 7 sticks together with the front 2 of still 1, and the centre is coated with very thin grease, gets rid of therebetween air and obtains suitable friction factor to remove the end.Rotating shaft 5 overcoats one stage clip 13 turns top cover 14 and changes 13 pairs of moving plates of stage clip, 7 additional pressure sizes, to reconcile time-delay.Axle 17 ends of water tap embed in the groove 16, make axle 17 and rotating shaft 5 interlocks.When external force made rotating shaft 5 rotate 90 °, the axle 17 and the moving plate 7 of water tap also rotated 90 °, and water tap is opened, and torsion spring 18 holds power simultaneously.After external force is cancelled, torsion spring 18 holds power and discharges, stir moving plate 7 backward rotation, because atmospheric pressure is to the effect of the spin friction power of generation between the front 2 of the front 2 of moving plate 7 and still 1, torsion spring 18 holds power and can only slowly discharge, the axle 17 that makes moving plate 7, rotating shaft 5, water tap is backward rotation slowly, the water tap time-delay closing, and device returns original state.

In different mechanisms, the corner of rotating shaft 5 can be different, and positive 2 geometrical shape also can be different (as fan-shaped etc.).Requiring under the less situation of moving plate 7 and still 1 diameter, can be designed to the form of multi-disc combination.

Claims

1, utilize ceramic wafer rotary friction to realize the device of time-delay, comprise rotating shaft (5), stage clip (13), it is characterized in that: when torsion spring (18) holds power and discharges, utilize the spin friction power that produces between the plane (2) of atmospheric pressure to the plane (2) of moving plate (7) and still (1) to realize delaying time.
