ABSTRACT:
FIELD OF THE INVENTION
The present invention is related to a register incorporating a toggle-joint mechanism between open and closed position. More particularly, in the present invention, air guide plates are easy to be pivotally connected on the base portion and the base portion is easy to configure to the outlet of the fan.
BACKGROUND OF THE INVENTION
The conventional large-sized cooling fan assembly (as shown in
FIG. 5
) includes: a case
5
with an outlet
51
in one end, wherein at least one fan
52
is disposed in the case
5
. The fan
52
could be a centrifugal blower. The fan
52
is corresponding to the outlet
51
in one end of the case
5
so as to blow the air generated by the fan
52
out from the outlet
51
. The fan
52
can be operated alone or together, depending on the heat dissipation needs. The conventional large-sized cooling fan assembly can operate the fan
52
alone or together with other fans. It will be fine to operate the fan
52
together with other fans. However, when single fan
52
in the case
5
is operated, the sir generated by the fan
52
usually will blow back to the case
5
and the hot air will cycle in the case
5
, which would be undesirable.
In another conventional large-sized cooling fan assembly (as shown in FIG.
6
), the cooling fan assembly includes: a case
6
with an outlet
61
in one end, wherein an air guide plate
62
is pivotally connected in the outlet
61
to work as a shelter. At least one centrifugal blower
63
is disposed in the case
6
. The fan
63
is corresponding to the outlet
61
in one end of the case
6
so that air generated by the fan
63
can output from the outlet
61
. The fan
63
can be operated alone or together, depending on the heat dissipation needs. Although the air guide plate
62
can prevent the shortcomings mentioned above, since the air guide plate
62
is a one-piece plate, the single fan
63
in the case
6
will lack air power to push the air guide plate
62
when being operated alone. The air guide plate
62
can not be opened. Therefore, the above conventional structures are not able to meet real needs.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide air guide plates easy to be pivotally connected on the base portion and make the base portion easy to configure to the outlet of the fan.
To achieve the above objective, the register incorporating a toggle-joint mechanism between open and closed position in the present invention is provided, which is configured to an outlet of an fan, including: a base portion, having a first pivoted joint and a second pivoted joint respectivety disposed on two ends and a third pivoted joint disposed between the first pivoted joint and the second pivoted joint, wherein the third pivoted joint is larger than the first pivoted joint and the second pivoted joint, a lock portion is disposed on the base portion; two air guide plates, each of them having a recess on its corresponding side for engaging each other, wherein each of the air guide plates has a pivoted axis respectively disposed at two edges of one end. By the pivoted axis, two air guide plates are pivotally connected with the first pivoted joint, the second pivoted joint and the third pivoted joint. Therefore, the air guide plates are easy to be pivotally connected on the base portion and the base portion is easy to configure to the outlet of the fan.
