Specific embodiment
Embodiments of the invention are 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 for rotating spray arm 1 is provided with vertical shaft 1.1, and it also includes vertically being fixed on tank base plate
Spray arm fixed column 6 and the spray arm mounting seat 5 for being connected with spray arm fixed column 6 that 3 bottom is installed for spray arm, shaft
1.1 are installed in rotation in spray arm mounting seat 5 by installing nut 2；By along week between shaft 1.1 and installation nut 2
It is relatively fixed to limit assembly is provided with.
Shaft 1.1 is provided with snap ring 1.1.1, and the outer wall of snap ring 1.1.1 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 the relatively-stationary fixture block 2.1 between installation nut 2.The upper surface of fixture block 2.1 is the engaging being engaged with limited block 1.1.2
Face, is sequentially provided with guiding surface 1.1.3 and recessed stopper slot 1.1.4 on snap-latch surface, and the width of stopper slot 1.1.4 is more than
Width equal to limited block 1.1.2 is so that limited block 1.1.2 is limited preventing from reversing into after stopper slot 1.1.4.So,
Even if because of variation in water pressure rotary speed can be caused unstable in washing process or certain amplitude vibrations will not also cause and turn
The position skew dislocation of axle 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 is installed, and the upper end of spray arm mounting seat 5 is provided with and prevents spray arm
The top of mounting seat 5 is from the bulge loop 5.2 for installing the abjection of the inner chamber of nut 2.The bottom of inner chamber of nut 2 is installed circumferentially arranged with multiple
For being engaged the small boss 2.2 to form rotational plane with the lower surface of bulge loop 5.2, the upper surface of small boss 2.2 is in peace
Loading nut 2 remains the plane contacted 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 little, rubs little such that it is able to keep rotating effect well.
Shaft 1.1 is provided with least one for the inner chamber with spray arm mounting seat 5 at the position of snap ring 1.1.1 bottoms
Perisporium be engaged 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 all the time good position-limiting action, prevents to incline.
The inner chamber of spray arm mounting seat is vertically provided with limit base, and limit base seat stretches into the inner chamber of described shaft, rotating shaft
The inner chamber in portion is provided with the spacing hole for coordinating with limit base gap.So, using fulcrum bearing can countershaft portion play very well
Supporting role, prevent 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 be provided with for external screw thread
The threaded interior hole 6.1 that installation portion 5.1 is engaged.So, installed using threaded connection, installation operation is very convenient.
The integral type of spray arm fixed column 6 is connected on the integrated water tumbler 7 of cleaning machine.So, the not only installation of spray arm fixed column
It is more firm, and the water stream channel that rotation spray arm is supplied water all is integrated on integrated water tumbler, not only save space, and water supply
Effect is more preferable.
The sealing ring 4 for sealing is provided between the lower end of spray arm fixed column 6 and tank base plate 3.Can prevent water from draining to water
Trench bottom, sealing effectiveness is more preferable.
Below only highly preferred embodiment of the present invention is described, but is not to be construed as limiting the scope of the invention.This
Invention is not only limited to above example, and its concrete structure allows to change.All protection models in independent claims of the present invention
Enclose interior made various change in the scope of the present invention.
