Preferably, when rotating to be able to achieve revolving part 30, lifting disk 40, which is only gone up and down, does not rotate movement, the present embodiment Overflow cascade washers use such as flowering structure: revolving part 30 includes rotating disk 31 and rotary shaft 32, and rotary shaft 32 is set to rotating disk 31 On rotation axis, rotating disk 31 makes rotating motion with respect to cover 50；Rotary shaft 32 is equipped with chuck 321 close to one end of cover 50, Side of the chuck 321 far from cover 50 is the first chuck plane, and the disk of lifting disk 40 close to 50 side of cover abuts the first chuck Plane；When rotating rotating disk 31, rotary shaft 32 is located remotely from each other or approaches with cover 50, but lifting disk 40 is gone up and down in rotary shaft 32 When, it can be driven and be gone up and down by the first chuck plane.Wherein, settable through-hole among lifting disk 40, is set in rotary shaft 32 to facilitate On.

It is had the benefit that using the above structure through rotation rotating disk 31 to realize the stepless changing in the form of spray, rotation Turntable 31 or rotary shaft 32 can be by being threadedly coupled, with (the angle when rotating rotating disk 31 with the formation of overflow cascade washers other component About 30~120 degree) realize that rotary shaft 32 infinitely, is gently gone up and down, be conducive to the adjustment of spray form, and pass through user Rotating disk 31 is rotated to adjust spray form, is more conform with use habit of the user using overflow cascade washers when.Simultaneously as with It is set on the rotation axis of rotating disk 31 in the rotary shaft 32 for providing chuck 321, when so that rotating disk 31 rotating, rotary shaft 32 Eccentric rotary will not occur, to avoid rotary shaft 32 push lifting disk 40 occur excessive radial displacement, to avoid adjustable column 10 with It is discharged between hole section 20 and excessive radial displacement occurs, influence the normal use of overflow cascade washers.

On the basis of above structure, it can be taken about " how passing through the lifting of the driving lifting disk 40 of revolving part 30 " as follows When two kinds of embodiments are to implement rotation revolving part 30, driving lifting disk 40 is gone up and down:

(1) structure that the revolving part 30 in one embodiment is fixedly connected using rotating disk 31 with rotary shaft 32, rotating disk 31 can rotate and go up and down simultaneously with rotary shaft 32.

Specifically, fixed rotary shaft 32, the two can be an integral molding structure in rotating disk 31, rotating disk 31 and cover 50 Between be connected through a screw thread, user rotate rotating disk 31 so as to produce relative rotation between rotating disk 31 and cover 50, at this time Rotating disk 31 is under the guiding of screw thread, while close to or away from cover 50, rotary shaft 32 due to being fixedly connected with rotating disk 31, therefore Rotary shaft 32 also rotates movement and elevating movement, and lifting disk 40 can take the intermediate through-hole that is equipped with to be sheathed on rotary shaft 32 On, 40 disk of lifting disk is blocked under the effect of gravity stops being connected to the first chuck plane, and when rotary shaft 32 rises, lifting disk 40 is revolved Shaft 32 pushes rising, and when rotary shaft 32 declines, lifting disk 40 can be declined by gravity.

(2) secondly the revolving part 30 in embodiment uses structure (such as Figure 10 of the connection seperated with rotary shaft 32 of rotating disk 31 It is shown, therebetween for circumference connection or star-like be connected), due to the utility model be by the rotation of driving rotating disk 31 with Realize adjustable column 10 lifting, but in order to enable rotating disk 31 rotate when, the flowing water cavity space between rotating disk 31 and cover 50 Constant, in order to keep the overall appearance of overflow cascade washers not change, rotating disk 31 in the present embodiment makes rotating motion but not It moves up and down, rotary shaft 32 makes rotating motion and moves up and down.

Specifically, rotating disk 31 is equipped with first through hole 311, and rotary shaft 32 is inserted in first through hole 311；32 edge of rotary shaft Axis body length direction successively includes the first shaft part, the second shaft part, third shaft part；First shaft part periphery is equipped with screw thread, rotary shaft 32 Each shaft part between have connection pipelined channel；First aperture 301 is set to the first shaft part, the second shaft part periphery and first 311 inner wall of through-hole is mutually twisted, and chuck 321 is arranged on third shaft part；As shown in figures 8 and 11, overflow cascade washers further includes upper cover part With fixing piece 70, upper cover part includes upper cover part ontology 61 and the guide through hole 62 on upper cover ontology, and the first shaft part is bolted in In guide through hole 62, the second sandwiched space is formed between upper cover part ontology 61 and cover 50,31 disk of rotating disk is set to the second folder If in space；It is fixedly connected between upper cover part and cover 50 by fixing piece 70；Due to 311 inner wall of first through hole and rotary shaft 32 are attached by way of the odd-shaped cross sections occlusion such as circumference connection or star-like connection (as shown in Figure 10), so that rotating disk 31 When rotation, first through hole 311 can transfer torque to rotary shaft 32 to drive rotary shaft 32 to rotate；Again due to rotating disk 31 with It is that fission connects and the first shaft part of rotary shaft 32 is spirally connected with the guide through hole 62 of upper cover part ontology 61 between rotary shaft 32, makes When obtaining the rotation of rotary shaft 32, rotary shaft 32 is by the rotation and lifting power that screw thread guides and then goes up and down greater than first through hole 311 to second The bite force of shaft part, rotary shaft 32 62 rises or falls in guide through hole, suitable for being risen or fallen in guide through hole 62, this When rotary shaft 32 the second shaft part 311 inner wall of wall surface and first through hole between relative position occur certain dislocation, but due to 32 heave amplitude of rotary shaft is smaller, and the skew range is smaller, does not influence structure use.Meanwhile if user is loose to rotating disk 31 Rotary force is unloaded, then rotating disk 31 can also be automatically replied is engaged with rotary shaft 32.

As noted previously, as the setting of fixing piece 70, is fixedly connected so that generating between upper cover part ontology 61 and cover 50. In addition, due to the limitation in the second sandwiched space, when rotating disk 31 is located in the second sandwiched space, can make rotary shaft 32 by After driving rotation, steadily gone up and down along guide through hole 62, and lifting moving does not occur for rotating disk 31, to guarantee subsequent rotating disk The further driving of 31 pairs of rotary shafts 32.Wherein, fixed column can be connected by screw to upper cover part ontology 61, cover 50.Together When, if user to 31 loose unloading rotary force of rotating disk, rotating disk 31 can also steadily, smoothly in the second sandwiched space Limitation under, automatically reply and be engaged with rotary shaft 32.
