Embodiment
Embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
As Figure 1-10 shows, a kind of rotation spray arm mounting structure for water tank cleaner, including located at tank inner chamber
The rotation spray arm 1 of bottom, the lower end of rotation spray arm 1 is provided with vertical shaft 1.1, and it also includes vertically being fixed on tank bottom plate
The spray arm fixed column 6 that 3 bottom is installed for spray arm and the spray arm mounting seat 5 for being connected with spray arm fixed column 6, shaft
1.1 are installed in rotation in spray arm mounting seat 5 by installing nut 2；Shaft 1.1 and install between nut 2 by along week
It is relatively fixed to provided with limit assembly.
Shaft 1.1 is provided with snap ring 1.1.1, and snap ring 1.1.1 outer wall is circumferentially spaced to be provided with multiple limited blocks
1.1.2, the inwall of installation nut 2 is circumferentially correspondingly provided with multiple for being engaged to realize shaft 1.1 with limited block 1.1.2
With installing the relatively-stationary fixture block 2.1 between nut 2.The upper surface of fixture block 2.1 is the engaging being engaged with limited block 1.1.2
Guiding surface 1.1.3 is sequentially provided with face, snap-latch surface and recessed stopper slot 1.1.4, and stopper slot 1.1.4 width be more than etc.
It is limited in limited block 1.1.2 width with causing limited block 1.1.2 to enter after stopper slot 1.1.4 to prevent from reversing.So, i.e.,
Make because of variation in water pressure rotary speed can be caused unstable in washing process or certain amplitude vibrations will not also cause rotating shaft
The position skew dislocation in portion, structure is more stable, and using effect is more preferable.
Periphery of the movable sleeve of nut 2 together in spray arm mounting seat 5 be installed, and spray arm mounting seat 5 upper end provided with preventing spray arm
Bulge loop 5.2 of the top of mounting seat 5 from the abjection of installation nut 2 inner chamber.The bottom of inner chamber of nut 2 is installed circumferentially arranged with multiple
It is engaged for the lower surface with bulge loop 5.2 to form the small boss 2.2 of rotational plane, the upper surface of small boss 2.2 is in peace
Loading nut 2 remains the plane being in contact with the lower surface of bulge loop 5.2 during rotating.So, nut and spray arm are installed
The contact area of the rotational plane of mounting seat is small, rubs small, so as to keep rotating effect well.
Shaft 1.1 is used for the inner chamber with spray arm mounting seat 5 at the position of snap ring 1.1.1 bottoms provided with least one
Perisporium be engaged with so that confining force of the spray arm in rotation process between shaft 1.1 and spray arm mounting seat 5 is preferably limited
Position ring.In this specific embodiment, as shown in figure 5, including spaced first spacing ring 1.1.5 and the second spacing ring
1.1.6.So, in spray arm in rotation process the first spacing ring 1.1.5 and the second spacing ring 1.1.6 and spray arm mounting seat 5
The perisporium of inner chamber has good position-limiting action all the time, prevents to tilt.
The inner chamber of spray arm mounting seat 5 is vertically provided with limit base 5.4, and limit base 5.4 stretches into the interior of described shaft 1.1
Chamber, the inner chamber of shaft 1.1 is provided with the spacing hole for being used for coordinating with the gap of limit base 5.4.So, can be to turning using fulcrum bearing
Axle portion plays good supporting role, prevents shaft from jumping.
The lower end of spray arm mounting seat 5 is provided with external screw thread installation portion 5.1, and spray arm fixed column 6 is provided with being used for and external screw thread
The threaded interior hole 6.1 that installation portion 5.1 is engaged.So, installed using being threadedly coupled, installation operation is very convenient.
The integral type of spray arm fixed column 6 is connected on the integrated cup 7 of cleaning machine.So, the not only installation of spray arm fixed column
It is more firm, and the water stream channel that is supplied water of rotation spray arm is all integrated on integrated cup, not only save space, and water supply
Effect is more preferable.
Being provided between the lower end of spray arm fixed column 6 and tank bottom plate 3 is used for sealed sealing ring 4.It can prevent water from draining to water
Trench bottom, sealing effectiveness is more preferable.
Only most preferred embodiment of the present utility model is described above, but is not to be construed as the limit to claim
System.The utility model is not only limited to above example, and its concrete structure allows to change.It is all in the utility model independent right
It is required that protection domain in the various change made in the utility model protection domain.
