Embodiment
As in Figure 3-5, a kind of miniature whirlpool water pump rear end cap and fan housing mounting structure, including fan housing 1 and rear end cap 2.
Screwed hole 21 is provided with the top of the outer wall of rear end cap 2, the inwall top of fan housing 1 is provided with connecting hole 11, screwed hole 21 and company
Hole 11 is connect to connect by screw 3.
Some groups of buckle structures are provided between other positions of the outer wall of rear end cap 2 and fan housing 1 inwall.In the present embodiment
The buckle structure of middle setting is two groups, can be set as more multigroup card as needed in practice.
Every group of buckle structure includes the annular card article 41 being arranged on the inwall of fan housing 1 and is arranged on the outer wall of rear end cap 2
Opening slot 42, the annular card article 41 can be snapped onto when rotating fan housing 1 in corresponding slot 42 and realize fan housing 1 with
Rear end cap 2 is connected together.
The outer wall bottom of rear end cap 2 is provided with circumferentially distributed evagination segmented bead 22, each place of segmented flange 22
The maximum outside diameter of circumference is more than the minimum diameter of the annular place circumference of card article 41, so that annular snap when fan housing 1 assembles
Bar 41 realizes axial stop bit when being offseted with flange 22.When the top of flange 22 is set as plane to form the assembling of annular card article 41
Axial block end face 221.
The gap length of adjacent ribs 22 is less than the length of annular card article 41, and connection bump is provided with above the gap location
23, the only tail end of connection bump 23 is connected with a side flange 22 and forms the opening slot 42 in the gap location.The connection
Projection 23 is made up of guide part 231 and pretension portion 232, and the lower surface 2311 and the lower surface 2321 of pretension portion 232 of guide part 231 are equal
For plane and the former set height that height is set less than the latter, the downside of guide part 231 forms guide groove 24 and is used for annular card article
41 guiding is caught in, and the downside in pretension portion 232 forms the pretension groove 25 that annular card article 41 is locked；The guide groove 24 and pretension
Groove 25 combines to form a complete slot 42.
Here, to make annular card article 41 successfully enter pretension groove 25, the guide part lower surface by guide groove 24
It is connected between 2311 and pretension subordinate end face 2321 by arc-shaped transitional surface 2322.
The distance h of the pretension subordinate end face 2321 and the top end face of flange 22 is not less than the width of the annular card article 41,
Its preferable embodiment, which is pretension subordinate end face 2321, is equal to the width of the annular card article 41 with the distance h of the top end face of flange 22
Degree so that annular card article 41 realizes effective locking once pretension groove 25 is entered.
The fan housing 1 is setting the inwall indent 12 of the annular position of card article 41.
The fan housing 1 uses pp environmentally-friendly plastic materials.
When mounted, fan housing 1 is inserted in outer end cap 2, until annular card article 41 encounters axial block end face 221, then turned
Dynamic fan housing 1 makes annular card article 31 enter guide groove 24 and until the end of pretension groove 25 and stop bit.Here, because of adjacent ribs 22
Gap is less than the length of annular card article 41, and now whole annular card article 41 is only most of all enters in slot 42, also one
Exceptionally reveal and offset and be connected with axial block end face 221, the locking of engaging is realized with this.Finally in fan housing 1 and outer end cap 2
Top is screwed into screw 3 and can complete to assemble.And in dismounting, need to first dismantle screw 3, and then backwards rotation fan housing 3 can release
The engaging constraint of buckle structure.
To sum up, the utility model fan housing combines a screw realization and the company of outer end cap by some connection buckle structures
Connect, wherein requirement of the attachment structure of single screw to machining accuracy is low, and the connection of buckle structure has assembling simplicity, assembling effect
The characteristics of rate is high, and just the dismounting with the later stage is safeguarded.
It is described above, only it is better embodiment of the present utility model, not the utility model is made any formal
Limitation, every any simple modification made according to technical principle of the present utility model to embodiment of above, equivalent variations or
Modification, in the range of still falling within technical solutions of the utility model.
