Abstract
The utility model discloses a kind of centrifugal fan of convenient disassembly, comprise fore shell and the back cover of blower fan, be provided with the first toothed surfaces on the left of described back cover upper end, the right-hand member of described back cover left side and the first toothed surfaces is respectively equipped with the first groove and the second groove; Described fore shell upper end is provided with the 3rd groove, is provided with and described first toothed surfaces can be had to connect the second toothed surfaces coordinated, be provided with the projection that can be connected with described second groove on the right side of lower end on the left of lower end; Described fore shell left end is connected with by the first roll pin one can embed the first groove the first curved profiled bar when fore shell and back cover are connected; Described back cover left end is connected with by the second roll pin one can embed the 3rd groove the second curved profiled bar when fore shell and back cover are connected.The utility model great advantage is: install fixing relatively more firm, dismantle also more simultaneously.
Description
Technical field
The utility model relates to a kind of wind energy facility, particularly relates to a kind of blower fan.
Background technique
The shell of blower fan is mostly adopted at present and is screwed, and its advantage is to be connected firmly, and deficiency is that dismounting is cumbersome, need more than, screw to remove, careless slightly screw is lost, and other places also will be gone to find screw, therefore, a kind of installation and removal all conveniently device is needed.
Model utility content
Technical problem to be solved in the utility model is, provides a kind of installation to fix relatively firmly, dismantles also conveniently centrifugal fan simultaneously.
For solving the problems of the technologies described above, the centrifugal fan of a kind of convenient disassembly that the utility model provides, comprise fore shell and the back cover of blower fan, be provided with the first toothed surfaces on the left of described back cover upper end, the right-hand member of described back cover left side and the first toothed surfaces is respectively equipped with the first groove and the second groove; Described fore shell upper end is provided with the 3rd groove, is provided with and described first toothed surfaces can be had to connect the second toothed surfaces coordinated, be provided with the projection that can be connected with described second groove on the right side of lower end on the left of lower end; Described fore shell left end is connected with by the first roll pin one can embed the first groove the first curved profiled bar when fore shell and back cover are connected; Described back cover left end is connected with by the second roll pin one can embed the 3rd groove the second curved profiled bar when fore shell and back cover are connected.
After adopting said structure mode, the utility model has the advantage of: after two toothed surfaces of fore shell and back cover are coordinated and by after projection and the second groove fit, be fixedly connected with by first, second curved profiled bar again, make the connection of fore shell and back cover very firm, dismantle also very convenient simultaneously.
Accompanying drawing explanation
Shown in Fig. 1 is surface structure schematic diagram of the present utility model.
Wherein: 1, fore shell; 2, back cover; 3, the first toothed surfaces; 4, the first groove; 5, the second groove; 6, the 3rd groove; 7, the second toothed surfaces; 8, projection; 9, the first roll pin; 10, the first curved profiled bar; 11, the second roll pin; 12, the second curved profiled bar.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, a kind of centrifugal fan of convenient disassembly, comprises fore shell 1 and the back cover 2 of blower fan, is provided with the first toothed surfaces 3 on the left of back cover 2 upper end, is respectively equipped with the first groove 4 and the second groove 5 at the right-hand member of back cover 2 left side and the first toothed surfaces 3; Be provided with the 3rd groove 6 in the upper end of fore shell 1, be provided with on the left of lower end and the first toothed surfaces 3 can be had to connect the second toothed surfaces 7 coordinated, on the right side of lower end, be provided with the projection 8 that can be connected with the second groove 5; Fore shell 1 left end is connected with by the first roll pin 9 one can embed the first groove 4 the first curved profiled bar 10 when fore shell 1 and back cover 2 are connected; Be connected with by the second roll pin 11 one can embed the 3rd groove 6 the second curved profiled bar 12 when fore shell 1 and back cover 2 are connected at back cover 2 left end.
The utility model is operation like this when concrete connection: after the second toothed surfaces 7 of fore shell 1 and the first toothed surfaces 3 of back cover 2 being coordinated and after projection 8 and the second groove 5 being coordinated, coordinated with the first groove 4 by the first curved profiled bar 10 again, the second curved profiled bar 12 is fixedly connected with the 3rd groove 6, make the connection of 1 fore shell and back cover 2 very firm, dismantle also very convenient simultaneously.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
