Abstract
The utility model discloses a kind of face plate of smoke exhaust ventilator connecting rod lifting device, pitman shaft is provided with between two vertical beams in range hood shell, motor and speed reducer is provided with in vertical beam, vertical beam lower end is also provided with rotating shaft, motor via reducer is connected with pitman shaft, panel both sides are respectively provided with top panel pole and lower panel pole, top panel pole and lower panel pole are all connected with crank connecting link, be welded as a whole with pitman shaft in the middle part of crank connecting link on described top panel pole, be connected with rotating shaft in the middle part of crank connecting link on described lower panel pole, the described crank connecting link other end is connected on range hood shell, the stable elevation of face plate of smoke exhaust ventilator can be realized by enforcement of the present utility model, and sound construction, not fragile.
Description
Technical field
The utility model relates to range hood.
Background technology
In prior art, the lifting of face plate of smoke exhaust ventilator is generally that the mode combined by tooth bar and slide rail is realized, this mode has the following disadvantages: along with long use, easily there is de-tooth or wear phenomenon in tooth bar, effectively cannot drive the lifting of kitchen ventilator panel, and once there be foreign matter to snap in slide rail, the lifting of panel can be affected equally; On the other hand, due to the restriction of inner space, this structure is generally monolateral transmission, easily trembles, affect the stability of panel lifting during panel lifting.
Utility model content
The utility model object is to overcome above-mentioned the deficiencies in the prior art, provides a kind of firm and durable, the lowering or hoisting gear that the lifting of face plate of smoke exhaust ventilator is more stable.
The technical solution of the utility model is: a kind of face plate of smoke exhaust ventilator connecting rod lifting device, pitman shaft is provided with between two vertical beams in range hood shell, motor and speed reducer is provided with in vertical beam, vertical beam lower end is also provided with rotating shaft, motor via reducer is connected with pitman shaft, panel both sides are respectively provided with top panel pole and lower panel pole, top panel pole and lower panel pole are all connected with crank connecting link, be welded as a whole with pitman shaft in the middle part of crank connecting link on described top panel pole, be connected with rotating shaft in the middle part of crank connecting link on described lower panel pole, the described crank connecting link other end is connected on range hood shell.
The beneficial effects of the utility model are: bar linkage structure is relative to tooth bar rail structure firm stable more, and production cost is lower, during work, because crank connecting link two ends connect pole and panel respectively, the motion of crank connecting link affects four fulcrums simultaneously, makes the lifting of face plate of smoke exhaust ventilator more stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: range hood shell 1, vertical beam 2, pitman shaft 3, motor 4, reductor 5, panel 6, top panel pole 7, lower panel pole 8, crank connecting link 9, rotating shaft 10.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Shown in composition graphs 1 and Fig. 2, a kind of face plate of smoke exhaust ventilator connecting rod lifting device, pitman shaft 3 is provided with between interior two vertical beams 2 of range hood shell 1, motor 4 and reductor 5 is provided with in vertical beam 2, vertical beam 2 lower end is also provided with rotating shaft 10, motor 4 is connected with pitman shaft 3 by reductor 5, panel 6 both sides are respectively provided with top panel pole 7 and lower panel pole 8, top panel pole 7 and lower panel pole 8 are all connected with crank connecting link 9, be welded as a whole with pitman shaft 3 in the middle part of crank connecting link 9 on described top panel pole 7, be connected with rotating shaft 10 in the middle part of crank connecting link 9 on described lower panel pole 8, described crank connecting link 9 other end is connected on range hood shell 1.
During work, motor via reducer drivening rod axle rotates, and pitman shaft drives the rotation of the crank connecting link on top panel pole, because crank connecting link two ends connect pole and panel respectively, the motion of crank connecting link affects four fulcrums simultaneously, thus realizes the stable elevation of panel.
