Technical field
The utility model relates to a kind of synchronous expansion retracting structure, relates in particular to a kind of fan synchronous expansion retracting structure of spreading the wings.
Background technique
Because the evolution in epoch and lifestyle change, people have adapted to daily life life and the work in semi-enclosed building lived in.Building only has gate, window that outdoor gas and indoor gas circulation are provided, people treat for a long time indoor have sultry, sweat or slight malaise symptoms such as dizziness, regulate machine, ventilating fan, ceiling fan or fan etc. so central air-conditioning system, pocket all can be installed at present in building, so as in the augmenter with outdoor air exchange, circulation.And ceiling fan is one kind of being widely used in the middle of the building, and ceiling fan has the characteristics that do not account for people's activity space and be installed on ceiling board, and cool house effect was more notable under collocation air-conditioning system, air conditioner used.
Apply for a patent application case case number No. 097209269 " the fan leaf structure improvement of spreading the wings " as TaiWan, China and be existing a kind of fan of spreading the wings, comprise a flabellum shelf structure and a fan leaf, this flabellum shelf structure is to have a housing and a supporting frame, this housing is to establish for this fan leaf group, be provided with a curling shape elastic component in the housing, and this elastic component one end and housing are fixed, housing is provided with at least one perforation, the housing bottom is provided with at least one groove, and this supporting frame one end is provided with a fixed base and establishes for the housing group, this fixed base also has and the corresponding positioning block of housing groove, make housing do the several angle turn along fixed base, fixed base convexes with one and screws togather groove and pass housing perforation and elastic component, and this screws togather groove and is provided with caulking groove and can fixes for the elastic component the other end;
Whereby, make supporting frame when rotation, housing can be borrowed the elastic component accumulation of energy, and borrows this elastic component oppositely to promote housing and fan leaf turn, and by fan leaf back and forth turn to increase the mobile effect of air.
Above-mentioned for having a kind of fan of spreading the wings now, because being subjected to elastic component elastic force respectively, each fan leaf promotes, therefore each fan leaf is starting between the normality running, and the normality running is central to collapse state, can't do synchronously to launch or folding because of elastic component elastic force factor causes each fan leaf, under this situation, cause the fan motor shaft of spreading the wings easily because of driving beat running under the blade center of gravity inequality, have noise under long-time the use and produce, and quicken its abrasion damaged condition.
The model utility content
Technical problem underlying to be solved in the utility model is, overcoming prior art can't synchronous expansion or fold the running noise that brought, quicken defective such as abrasion damage, and provide a kind of spreading the wings to fan the synchronous expansion retracting structure, fan leaf is operated by collapse state synchronous expansion to normality, and the normality running is down synchronously to folding halted state.
In order to reach above-mentioned purpose, the utility model fan synchronous expansion retracting structure of spreading the wings includes a drive unit, several housings, several connecting rods and several fan leafs composition, wherein:
This drive unit is provided with several supporting frames, and this supporting frame is provided with a pivot post;
This housing, it is provided with a pivot hole that supplies the pivot post to wear pivot;
This connecting rod is hubbed at two adjacent housings respectively with two ends;
This fan leaf, the one end is provided with the combination section of this housing of assembly, and this combination section is provided with the through hole that a confession pivot is worn pivot.
This connecting rod is integrally formed in crooked linkage section two ends by two crooked joining sections.
In view of the above, this housing pivots to supporting frame with the connecting rod locking phase, and this blade and this housing are synchronous expansion or fold simultaneously, and avoiding in the past, fan leaf can't fold defectives such as the acceleration that is brought wears away, running noise by synchronous expansion.
Above-mentioned this housing is provided with several perforation around the pivot hole, and corresponding each perforation in the combination section of this fan leaf is provided with a screw fixed hole, and the corresponding perforation of this connecting rod joining section is provided with a perforation, screws togather perforation, perforation and screw fixed hole linking rod, housing and fan leaf with a screw tightening in addition.
This connecting rod is integrally formed in crooked linkage section two ends by two crooked joining sections, and this joining section and linkage section bending direction are not in the same way, during this fan leaf collapse state, this bending joining section pivot post of being dodged, when making the fan leaf collapse state near drive unit.
The beneficial effects of the utility model are fan leaf is operated by collapse state synchronous expansion to normality, and the normality running to be down synchronously to folding halted state.
