The utility model is intended to solve above-mentioned mentioned technical problem, provides the charging type electric fan of a kind of sound construction, long service life.
The utility model is realized by following technological scheme:
A kind of charging type electric fan, comprises base and is fixed on the Electric actuator on base, and base comprises housing, be installed in the control panel on housing and be arranged on the end cap of lower housing portion, the flange towards base that end cap comprises base plate and extends along bottom edge; End cap is connected with housing with securing means by limit structure, securing means comprises fastening screw trip bolt, is arranged at the through hole on end cap and is installed in the first fixing column in housing, the end of the first fixing column is provided with first counterbore coaxial with through hole, and fastening screw trip bolt coordinates with the first counterbore through through hole; First fixing column is fixed by the inwall of fixing frame and housing.
Further, described fixing frame comprises at least two blocks of side plates and connecting lateral plate end horizontally disposed transverse slat of being vertically fixedly arranged on inner walls, and the first fixing column is vertically fixedly arranged on transverse slat.
Further, the inwall of described housing extends the stiffening plate be connected with the first fixing column and side plate.
Further, the edge of described through hole extends second fixing column coaxial with the first fixing column towards the direction of housing, the end of the second fixing column is provided with the second counterbore being sleeved on the first fixing column end.
Further, described limit structure comprises the riser be arranged on end cap inwall and the restraining groove be arranged between riser and flange.
Further, described first fixing column, fixing frame and housing are integrated molding and forming structure.
Further, the base plate of described end cap and flange are provided with radiation hole.
Beneficial effect is: a kind of charging type electric fan of the present utility model, on the inwall of housing, is not only provided with the first traditional fixing column, on the first fixing column, also adds the structure of fixing frame and stiffening plate, significantly increase the intensity of the first fixing column; In addition, end cap also also add the second fixing column being sleeved on the first fixing column, second fixing column is provided with the counterbore be sleeved on the first fixing column, not only makes the assembling of end cap and housing more convenient, and make to be connected between end cap with housing more firm.Said structure not only adds the structural strength of electric fan, making electric fan not fragile when colliding, extending the working life of electric fan, and it is more convenient that electric fan is assembled.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is the schematic diagram of base in a kind of charging type electric fan in the utility model;
Fig. 2 is the cut-away view of Fig. 1 middle shell;
Fig. 3 is the worm's eye view of end cap in Fig. 1;
Fig. 4 is the schematic diagram of end cap in Fig. 1.
Embodiment
A kind of charging type electric fan as Figure 1-Figure 4, the Electric actuator comprising base 1 and be fixed on base 1, base 1 is for Electric actuator that is fixing and support top; Base 1 comprises housing 2, be installed in the control panel 3 on housing 2 and be arranged on the end cap 4 of housing 2 bottom, accommodates the electronic component controlling electric fan in housing 2.The flange 42 towards base 1 that end cap 4 comprises base plate 41 and extends along the edge of base plate 41, first the effect of end cap 4 is the electrical apparatus element in protective housing 2, be secondly make electric fan can firm placement in the plane; End cap 4 is connected with housing 2 with securing means by limit structure, securing means comprises fastening screw trip bolt, is arranged at the through hole 43 on end cap 4 and is installed in the first fixing column 21 in housing 2, first fixing column 21 is generally in cylindric, first counterbore 22 coaxial with through hole 43 is provided with in the end of the first fixing column 21, fastening screw trip bolt coordinates with the first counterbore 22 through through hole 43, is tightened together by end cap 4 with housing 2.
First fixing column 21 is installed on the inwall of housing 2 by fixing frame.Described fixing frame comprises at least two blocks of side plates 23 and connecting lateral plate 23 end being vertically fixedly arranged on housing 2 inwall and horizontally disposed transverse slat 24, first fixing column 21 is vertically fixedly arranged on transverse slat 24.The setting that side plate 23 can be parallel to each other, also can be arranged in a crossed manner; When considering that side plate 23 is arranged in parallel structural strength high, also easily make, so generally adopt the mode be parallel to each other to arrange side plate 23.
The inwall of described housing 2 extends the stiffening plate 25 be connected with the first fixing column 21 and side plate 23.Stiffening plate 25 makes housing 2, first fixing column 21 and side plate 23 three be fixed into an entirety, greatly improves the intensity of the first fixing column 21.
The edge of described through hole 43 extends on the end of the second fixing column 44, second fixing column 44 coaxial with the first fixing column 21 towards the direction of housing 2 and is provided with the second counterbore 45 being sleeved on the first fixing column 21 end.When installing end cap 4, the second counterbore 45 is first sleeved on the first fixing column 21, then tightens screw, such structure both ease of assembly, also strengthens the join strength of end cap 4 and housing 2 simultaneously.
Described limit structure comprises the riser 46 be arranged on end cap 4 inwall and the restraining groove 47 be arranged between riser 46 and flange 42.Housing 2 is snapped in the restraining groove 47 of end cap 4, avoids the mutual movement between end cap 4 and housing, meanwhile, also make the seam between end cap 4 and housing 2 attractive in appearance.
Described first fixing column 21, fixing frame and housing 2 are integrated molding and forming structure.Integrated formed structure not only simplifies processing technology, and make between end cap 4 and housing 2 connect more firm.
The heat produced to make the electronic component in housing 2 comes out in housing 2, and the base plate 41 and flange 42 of end cap 4 are provided with radiation hole 48.Certainly, end cap 4 can make base plate 41 have certain distance, so that the radiation hole 48 on base plate 41 better dispels the heat with the plane of placing electric fan.
