Embodiment

Fig. 1 and Fig. 2 are refer to, for the choke device 10 of the first better embodiment of the invention.The choke device 10 includes a frame Frame 12, one first tumbler 14 and one second tumbler 16.

The framework 12 includes a cylindric main body 121 and the phase to be stretched out respectively by the rear and front end of the main body 121 Mutually two parallel plate bodys 125.It is circular that the middle part of the main body 121, which is provided with one through the cross section of the front and back end of the main body 121, Receiving space 124.Each plate body 125 is respectively equipped with a clamping hole 126 at neighbouring corner.The appearance and size of the framework 12 and should The appearance and size and flabellum receiving space 23 of the cross-sectional area of receiving space 124 and the fan board 21 of common standard fan 20 Cross-sectional area is identical.The mounting means of the framework 12 is also identical with the mounting means of standard fan 20.

First pivoting hole 122 being connected with the receiving space 124 is respectively equipped with the middle part of the both sides of the main body 121, The both sides of the main body 121 are respectively equipped with second pivoting hole 123 being connected with the receiving space 124 at neighbouring top. In present embodiment, two first pivoting hole 122 is with two second pivoting hole 123 in same vertical plane.

First tumbler 14 include one first wind-retarding plate 141 and from the top of first wind-retarding plate 141 middle to One first pivot rods 143 that both sides are stretched out.First wind-retarding plate 141 is the recurvate arc in one or two side, the top of arc Portion 145 is a horizontal plane, and bottom 147 is in middle downward projection of arc.First pivot rods 143 arrive the bottom 147 The vertical range of middle is less than or equal to vertical between the plate body 125 of two first pivoting hole 122 to the front end of framework 12 Distance.

Second tumbler 16 includes the recurvate one second curved wind-retarding plate 161 in both sides and by second choke One second pivot rods 163 that the middle at the top of piece 161 is stretched out to both sides.The bottom 165 of second wind-retarding plate 161 is horizontal, Top 167 is in the middle arc projected upwards.Second pivot rods 163 are less than or equal to the vertical range of the bottom 165 should The vertical range that two second pivoting holes 123 are arrived between the plate body 125 of the front end of framework 12.

Fig. 3 is refer to, when assembling the choke device 10, makes the flexural deformation of the first pivot rods 143 and is contained in collecting sky Between in 124.The both ends of first pivot rods 143 are respectively aligned to two first pivoting holes 122 of the framework 12, first pivot rods 143 elastic recoverys make the both ends of first pivot rods 143 be respectively clamped into two first pivoting hole 122, so as to which this first be rotated Part 14 is rotationally installed in the receiving space 124.First wind-retarding plate 141 sagging is barred from the receipts by Action of Gravity Field is vertical Hold the lower half in space 124, the both sides and bottom 147 of first wind-retarding plate 141 abut the lower half of receiving space 124 respectively Both sides and bottom.Make the flexural deformation of the second pivot rods 163 and be contained in the receiving space 124.By second pivot rods 163 Both ends be respectively aligned to two second pivoting holes 123 of the framework 12, the elastic recovery of the second pivot rods 163 makes second pivot rods 163 both ends are respectively clamped into two second pivoting hole 123, so as to which second tumbler 16 is rotationally installed in into collecting sky Between in 124.Second wind-retarding plate 161 is by the vertical sagging first half for being barred from the receiving space 124 of Action of Gravity Field, second resistance The both sides and top 167 of wind piece 161 abut the both sides and top of the first half of receiving space 124, second wind-retarding plate 161 respectively Bottom 165 abut first wind-retarding plate 141 top 145.By first, second wind-retarding plate 141,161, into the collecting The distinguished and admirable of space 124 can be blocked substantially.

Fig. 4 is refer to, when the choke device 10 is acted on by larger wind-force from the front to the back, first, second choke Piece 141,161 forward and is rotated up around corresponding first, second pivot rods 143,163.When wind-force is sufficiently large, this First, the second wind-retarding plate 141,161 rotatable 90 degree, now windage is minimum.In the process, first, second wind-retarding plate 141, 161 are all contained in the receiving space 124 all the time, will not stretch out framework 12.

When the failure of a standard fan 20 in the cabinet 30 of an electronic product and can not find replace fan when, can be by the standard Fan 20 is pulled down and loads the choke device 10 with identical mounting means, such as the choke in Fig. 1 between two standard fans 20 Shown in device 10.First, second wind-retarding plate 141,161 of the choke device 10 is in naturally vertical hang and can stopped distinguished and admirable Backflow.

If space allows, user can install a choke device 10 in the front end of a standard fan 20, such as the leftmost side in Fig. 1 Shown in choke device 10.When standard fan 20 runs well, first, second wind-retarding plate 141,161 of the choke device 10 is by sufficiently large Wind-force effect forward upward rotate 90 degree, do not influence the air-out of standard fan 20.During 20 failure of standard fan, this first, Two wind-retarding plates 141,161 return to natural vertical hang, so as to stop distinguished and admirable backflow.

Fig. 5 and Fig. 6 are refer to, for the choke device 50 of the second better embodiment of the invention.Compared with choke device 10, the resistance First wind-retarding plate 141 of the first tumbler 14 has been substituted for the first wind-retarding plate convex under flat semicircle arc by wind device 50 541。
