Abstract
The utility model discloses a kind of row's fan blade device, comprise air draft leaf and lazy-tongs; Described air draft leaf is provided with two, the adjacent setting of rotating shaft of two air draft leaves; Described lazy-tongs are controlled two air draft leaves and are synchronously rotated.The utility model is controlled two air draft leaves by lazy-tongs and is synchronously rotated, overcome air draft leaf be affected by gravity can not synchronous on-off drawback, make the utility model arbitrarily angled work in space, air draft leaf can be realized synchronous on-off, thereby guarantee that two air draft leaves can open and close the air outlet of exhaust outlet adapter smoothly, under the prerequisite that does not affect machine operation, effectively prevent that foreign material from entering machine intimate by exhaust outlet, guarantee machine safe operation.
Description
Technical field
The utility model relates to a kind of row's fan blade device.
Background technology
Mobile air conditioners etc. need the machine of air draft, its exhaust duct is arranged on window or body of wall by exhaust outlet adapter, because the air outlet of existing exhaust outlet adapter is all open design, therefore the foreign material such as rainwater, leaf, mouse likely enter machine by the air outlet of exhaust outlet adapter, thereby the safe operation of machine is impacted.In order to prevent that the foreign material such as rainwater, leaf, mouse from entering machine by the air outlet of exhaust outlet adapter, applicant is thought of as a kind of row's fan blade device of exhaust outlet adapter design, by resetting means, provide reset force, can when machine does not use, close in time the air outlet of exhaust outlet adapter.Angle during due to the installation of exhaust outlet adapter need to be set according to actual conditions, under some angle, the impact that air draft leaf is subject to gravity can not realize synchronous on-off, arranges in this case fan blade device and just can not successfully open and close the air outlet of exhaust outlet adapter.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of air draft leaf assembly that can synchronously rotate, and guarantees that the air outlet of exhaust outlet adapter can successfully be opened and closed.
In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of row's fan blade device, comprises air draft leaf and lazy-tongs; Described air draft leaf is provided with two, the adjacent setting of rotating shaft of two air draft leaves; Described lazy-tongs are controlled two air draft leaves and are synchronously rotated.
Described lazy-tongs comprise at least one group of synchromesh gear assembly; Described synchromesh gear assembly by two be separately fixed on two air draft leaves, and the identical gear of intermeshing structure form.
Described synchromesh gear assembly is provided with upper and lower two groups.
Gear in described air draft leaf and synchromesh gear assembly mounted thereto is integral type structure.
Adopted after technique scheme, the utlity model has following beneficial effect: (1) the utility model is controlled two air draft leaves by lazy-tongs and synchronously rotated, overcome air draft leaf be affected by gravity can not synchronous on-off drawback, make the utility model arbitrarily angled work in space, air draft leaf can be realized synchronous on-off, thereby guarantee that two air draft leaves can open and close the air outlet of exhaust outlet adapter smoothly, under the prerequisite that does not affect machine operation, effectively prevent that foreign material from entering machine intimate by exhaust outlet, guarantee machine safe operation.
(2) synchromesh gear assembly of the present utility model by two be separately fixed on two air draft leaves, and the identical gear of intermeshing structure form, by two pitch wheel transmissions, two air draft leaves can be remained synchronously, simple in structure, cost is low, easy for installation.
(3) synchromesh gear assembly of the present utility model is provided with upper and lower two groups, can guarantee stability when two air draft leaves open and close.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is:
Air draft leaf 1, synchromesh gear assembly 2.
The specific embodiment
(embodiment 1)
See Fig. 1, row's fan blade device of the present embodiment, comprises air draft leaf 1 and lazy-tongs.
Air draft leaf 1 is provided with two, the adjacent setting of rotating shaft of two air draft leaves 1.Lazy-tongs are controlled two air draft leaves 1 and are synchronously rotated.Lazy-tongs comprise at least one group of synchromesh gear assembly 2.Synchromesh gear assembly 2 by two be separately fixed on two air draft leaves 1, and the identical gear of intermeshing structure form.Synchromesh gear assembly 2 preferably arranges upper and lower two groups.Air draft leaf 1 is integral type structure with the gear in synchromesh gear assembly 2 mounted thereto.
The principle of row's fan blade device of the present embodiment is: in the process of two air draft leaf 1 opening and closing, pass through two pitch wheel transmissions, make two air draft leaves 1 can remain synchronous, overcome air draft leaf 1 be affected by gravity can not synchronous on-off drawback, make row's fan blade device arbitrarily angled work in space of the present embodiment, air draft leaf 1 can be realized synchronous on-off, thereby guarantee that two air draft leaves 1 can open and close the air outlet of exhaust outlet adapter smoothly, under the prerequisite that does not affect machine operation, effectively prevent that foreign material from entering machine intimate by exhaust outlet, guarantee machine safe operation.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
