Abstract
The utility model relates to a hanging device of a scavenger fan, which mainly comprises a hanging spring which is connected with a scavenger fan and a pull rope which is connected with the hanging spring and a top wall. The utility model has simple structure. The hanging spring is fixedly clamped in a box body by proper elasticity. The disassembly and the assembly do not need a tool and are convenient and simple, and can not injure hands. The hanging device of a scavenger fan adopts the hanging form of a pyramid shape and is fixed by matching with a ceiling. The pressure to the ceiling is reduced. The installation is more firm and safe.
Description
Technical field
The utility model relates to a kind of ventilation fan, specifically a kind of lifting device of ventilation fan.
Background technique
The ventilation fan kind of people's use now is a lot, have vertically be installed on the wall, also have and be vertically fixed on the ceiling board, the mode that great majority are installed is to adopt the form of inlaying that the ventilation fan all around is fixed in wall or the ceiling board earlier, utilizes the screw that interts in wall or ceiling board vertically to be completely fixed again.The installation drawback of this form is more, particularly be installed in the ventilation fan on the ceiling board, need utilize instrument screw to be screwed on the plank on the ceiling board of fixing ventilation fan during installation from lower to upper, it is big and waste time and energy that screw is accurately hammered into difficulty, injure the operator easily, install cumbersome, and because the weight of ventilation fan all is pressed on the ceiling board, do not have other strong points, cause after long-time ceiling board distortion and noise to become problem such as big easily.
Summary of the invention
The purpose of this utility model provides a kind of ventilation fan lifting device simple, easy for installation of making.
According to the above-mentioned purpose requirement, the utility model is realized by the following technical solutions:
A kind of ventilation fan lifting device mainly comprises lifting spring that is connected with ventilation fan and the stay cord that connects lifting spring and top wall.
Lifting spring described in the utility model adopts resilient metal strip to be bent into, the intermediate portion bending of metal bar is the thin ellipticity in two ends broad in the middle, two end portions is bent into two semicircles respectively, two halves circular symmetry formation one circle in the same plane, and semicircular two end portions and elliptoid intermediate portion are perpendicular.This lifting spring can be pinched two semicircle places or pushed by external force at lifting spring ellipticity intermediate portion along diametric(al) with hand, and the ellipticity of lifting spring is partly dwindled, and utilizes the elasticity of metal self can recover again after unclamping.The lifting spring can be three or four, by be connected the size of erection opening partly being complementary with the thin of intermediate portion and circular adjoiner on the casing in the erection opening that interts on the ventilation fan casing with casing less than lifting spring ellipticity intermediate portion than coarse position; With the erection opening on the lifting spring aligning ventilation fan casing, press with hand one, lifting spring ellipticity intermediate portion will be subjected to the extruding of erection opening external force and the place is little, the pressure that adds left-hand seat, lifting spring ellipticity part is just exposed the erection opening of casing, lift spring simultaneously and utilize the elasticity of self to return to previous condition again, larger part and two semicircle places make the lifting spring clip in erection opening in the middle of the lifting spring ellipticity.Install on the middle room top wall in ventilation fan hole being fixed on; Expose casing erection opening part top at each lifting spring and all tie up a stay cord, the other end concurrent of every stay cord connects directly fixing or is fixed in the room top wall by a suspension hook, the free adjustment pulling rope length, making lifting device be pyramid shape is suspended in ventilation fan under the top wall, and by the room ceiling board to ventilation fan about, the location of fore-and-aft direction, ventilation fan is completely fixed.Above-mentioned stay cord can be iron wire or other analogs.
The utility model is simple in structure, and the lifting spring fixes in casing by the elasticity of self, and dismounting does not need tool using, convenient and simple and do not hinder hand, and adopt the lifting form of pyramid shape, be equipped with the fixing of ceiling board, reduced pressure, firm more, safety have been installed ceiling board.
Description of drawings
Accompanying drawing 1 is the general structure schematic representation of the utility model specific embodiment; Accompanying drawing 2 is the lifting spring scheme of installation of the utility model specific embodiment; Accompanying drawing 3 is the utility model lifting spring structure schematic representation.
Embodiment
For the ease of those skilled in the art's understanding, lift a specific embodiment below in conjunction with accompanying drawing the utility model structural principle be further described in detail:
Be the general structure schematic representation of the utility model one specific embodiment as shown in Figure 1, earlier suspension hook is fixed on and installs on the middle room top wall in ventilation fan hole, four lifting springs 2 are installed on the erection opening on four angles of ventilation fan casing 1, bind stay cord 3 respectively above the lifting spring 2, the other end concurrent of every stay cord 3 connects into an end and is fixed on the suspension hook 4, regulates stay cord 3 length and tighten.Simultaneously as shown in Figure 3, lifting spring 2 is bent into for the round and elastic metal bar for the cross section, the intermediate portion bending of metal bar is the thin ellipticity in two ends broad in the middle, two end portions is bent into two semicircles respectively, two halves circular symmetry formation one circle in the same plane, and semicircular two end portions and elliptoid intermediate portion are perpendicular.Again as shown in Figure 2, when lifting spring 2 is installed, with lifting spring 2 from ventilation fan casing 1 intake grill upwards through the erection opening 5 on 1 four jiaos of the casings, make the lifting spring clip in erection opening 5 by larger part and two semicircle places in the middle of lifting spring 2 ellipticities, even utilize the elasticity of lifting spring 2 that lifting spring 2 also can not dropped from casing under the situation that does not lift iron wire.
The foregoing description is a preferred version of the present utility model; the main invention thinking of the utility model is the fixing ventilation fan of the mode by lifting; under the situation that does not break away from the present utility model thinking, the replacement of any conspicuous replacement such as stay cord etc. all belongs within the utility model protection domain.
