The above-mentioned known technology of picture due to button bit 106 will be set in addition, so just needs to make in addition new die, and process butt-joint and the technique such as dust, and its cost is higher; And, in the time of on being fixed to the ventilation fan framework, there is problems such as wasting man-hour.
The model utility content
The object of the present invention is to provide a kind of ventilation fan, have simple joint structure.
For achieving the above object, the invention provides a kind of ventilation fan, comprise ventilation fan body, joint, electric component box, be provided with on ventilation orifice that air is passed, end face at framework in the one side of the ventilation fan framework that is provided with lower aperture and be provided with electric component box, it is characterized in that: be provided with the fastening structure that fastens with joint on electric component box.
Described fastening structure is to be provided with the tabs that fastens with joint on the base plate of electric component box.
Described fastening structure is that outer the covering at electric component box is provided with the tabs that fastens with joint.
Described tabs is outward-dipping setting.
Described tabs and electric component box are formed as one.
Be provided with joint and insert guide surface on the lid of electric component box.
The invention has the advantages that, simplified structure improves operability, reduces costs.
Description of drawings
Fig. 1 is the known technology schematic diagram;
Fig. 2 is first embodiment's schematic diagram;
Fig. 3 is the first embodiment's partial enlarged drawing;
Fig. 4 is second embodiment's schematic diagram.
Embodiment
As shown in Figure 2, be first embodiment's schematic diagram.Ventilation fan 100 comprises the ventilation fan body 110, joint 200, the electric component box 130 that are provided with flabellum 101 (not shown), motor 102, are provided with the framework 103 etc. of lower aperture.Electric component box 130 is positioned on the end face 115 of framework 103.One side 113 at ventilation fan framework 103 is provided with framework exhaust outlet 104 (not shown) that air is passed, one end 201 of described joint 200 is connected with framework exhaust outlet 104 (not shown), and the other end 202 is connected with the pipeline (not shown).Be provided with the tabs 132 integrally formed with this base plate 131 on the base plate 131 of electric component box 130, for making joint 200 and the ventilation fan outward-dipping tabs 132 that arranges that fastens, be provided with on joint 200 and opening 105 that tabs 132 engages mutually.
In the present embodiment, just need not as known technology, button bit 106 need to be set additionally.
When installing, first joint 200 is fixed on ceiling board, then ventilation fan 100 is aimed at joint 200 from bottom to top, after being about to opening 105 that tabs 132 integrally formed on the base plate 131 with electric component box 130 and joint 200 be provided with aligning engaging mutually, thereby it is mounted and fixed on ceiling board the most at last.
As shown in Figure 3, be the first embodiment's partial enlarged drawing.Due to above-mentioned tabs 132 for being obliquely installed, its toe angle β is arranged to comparatively mild, described its toe angle is arranged to refer to comparatively gently that the angle β that forms between the elongation line 135 of tabs 132 front ends 153 and electrical equipment component box plate is less, when from bottom to top this tabs 132 being snapped in the opening 105 of joint, it has guiding function, and tabs 132 can more smooth and easyly be snapped in the opening 105 of joint 200; The rear angle of this tabs 132
More be obliquely installed described rear angle than front end 153
More be obliquely installed the angle that forms between the elongation line 136 that refers to tabs 132 rear ends 163 and electrical equipment component box plate than front end 153
Larger, after being fixed in this tabs 132 buckles into the opening 105 of joint, can forming interference fit between the opening 105 of this tabs 132 and joint 200, thereby make it more firm with coordinating of joint 200.
As shown in Figure 4, be second embodiment's schematic diagram.Be with first embodiment's difference, the tabs 132 that fastens with opening 105 on joint 200 integrally formed, on the outward-dipping enclosing cover 133 that is arranged on electric component box 130, rather than on base plate 131.
In the present embodiment, equally also need not as known technology, extra button bit 106 need to be set.When installing, first joint 200 is fixed on ceiling board, then ventilation fan 100 is aimed at joint 200 from bottom to top, after being about to opening 105 that tabs 132 integrally formed on the enclosing cover 133 with electric component box 130 and joint 200 be provided with aligning engaging mutually, thereby it is mounted and fixed on ceiling board the most at last.
Again as shown in Figure 4, be provided with joint 200 on the enclosing cover 133 of electric component box 130 and insert guide surface 300.Described joint inserts guide surface 300 and is included in the wall 301 that the two ends, left and right 201 of clamping joint frame 210,202 position are provided with and the plane of inclination 302 that is connected with these walls 301.
During installation, the tabs 132 that ventilation fan is provided with need to be fixed on ceiling board on the opening 105 of joint 200 upper ends mutually aim at and engage.But when the downside from ceiling board lifted ventilation fan 100 and carries out installation exercise, the tabs 132 of ventilation fan 100 was difficult for aiming at the opening 105 of upper end of joint.After guide surface 300 was set, ventilation fan body 110 can be arranged on ceiling board along the upper end of joint 200 by making above-mentioned plane of inclination 302.At this moment, the wall 301 that inserts guide structure due to joint 200 is arranged at the position of clamping joint frame 210 from the right and left, so, butt joint 200, the dislocation of left and right directions can not occur in ventilation fan body 110 when mounted.Butt joint 200, the installation of ventilation fan 100 can be easy to carry out.
