Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in further detail.
As depicted in figs. 1 and 2, the retractable blades on a kind of blower fan, it is used for being arranged on axial fan hub 1, its quantity is excellent
Electing three as, and be distributed in hexagonal angle, this blade 2 includes, the fixed part 20 being connected with wheel hub 1 is slidably connected with fixed part 20
Pars contractilis 21, and drive pars contractilis 21 longitudinal sliding motion power set.Bolt and wheel are passed through in one end of described fixed part 20
Hub 1 is fixing to be connected, and the other end is open ports, and one end of described pars contractilis 21 is arranged on the inside of fixed part 20 through open ports,
And be slidably connected with the inner chamber of fixed part 20, the length of described fixed part 20 stretch not less than blade 2 after three points of greatest length
One of, it is preferable that the length of fixed part 20 is more than the length of pars contractilis 21, so that its internal die cavity can accommodate pars contractilis 21.
As it is shown on figure 3, specifically, described pars contractilis 21 includes one-level pars contractilis 211 and two grades of pars contractilis 212, described one
One end of level pars contractilis 211 stretches to the inside of fixed part 20, and is slidably connected with fixed part 20, and the other end is open ports, and
Being slidably connected with two grades of pars contractilis 212, the end of two grades of pars contractilis 212 is blade tip.At fixed part 20, one-level pars contractilis 211, two
Level pars contractilis 212 inside be provided with scalable steel pipe, described scalable steel pipe is three joints, and the most successively with fixed part 20,
211, two grades of pars contractilis 212 of one-level pars contractilis connect.Preferably, the length of fixed part 20 is more than the length of one-level pars contractilis 211
Length more than two grades of pars contractilis 212.
Owing to one-level pars contractilis 211 is positioned at the middle part of blade 2, its change of shape is less, it is simple to shrink, and uses multi-stage expansion
The setting in portion makes blade 2 shrink scope greatly, i.e. blade 2 area change is big, and subject range is wider.
As shown in Figure 4, described scalable steel pipe is rectangular tube, is positioned at blade 2 internal, and fixing with blade 2 inner chamber is connected,
Being effectively increased the intensity of blade 2, scalable steel pipe includes, the fixing steel pipe 10 being connected with fixed part 20, with one-level pars contractilis
The 211 fixing one-level steel pipes 11 connected, two grade steel pipes 12 being connected fixing with two grades of pars contractilis 212.Fixing steel pipe 10, one-level steel
11, two grades of steel pipes 12 of pipe are sequentially connected with, and can relatively slide.
As it is shown in figure 5, described power set are hydraulic cylinder, be arranged in scalable steel pipe, including with fix steel pipe 20 even
The cylinder body 3 connect and the push rod 4 being connected with two grades of steel pipes 12, when push rod 4 is to cylinder body 3 movement outside, will promote scalable steel pipe
Elongated, and then make blade 2 elongated, when push rod 4 is retracted in cylinder body 3, scalable steel pipe shortens, and blade 2 length diminishes.
The length of described fixing steel pipe 10 is less than the length of fixed part 20, and the open ports certain distance away from fixed part 20 sets
Putting, this distance is the move distance of one-level pars contractilis 211；It is outside that described one-level steel pipe 11 one end extends to one-level pars contractilis 211,
And be inserted in fixing steel pipe 10, it is internal that the other end is positioned at one-level pars contractilis 211, and away from one-level pars contractilis 211 port one spacing
From setting, this distance is the move distance of two grades of pars contractilis 212.Described two grades of steel pipe 12 one end extend to two grades of pars contractilis 212
Outside, and be inserted in one-level steel pipe 11, it is internal that the other end is positioned at two grades of pars contractilis 212.One-level pars contractilis 211 is to fixed part
When 20 inside are mobile, owing to the outer wall of fixing steel pipe 10 is connected with the inner chamber of fixed part 20, when the end of one-level pars contractilis 211 is touched
When contacting the end face of fixing steel pipe 10, now, one-level pars contractilis 211 will be unable to be further continued for moving to fixed part 20 inside, this position
It is set to the extreme position of the one-level pars contractilis 211 indentation in fixed part 20.In like manner, when the end and of two grades of pars contractilis 212
Level steel pipe 11 end contact time, this position is two grades of pars contractilis 212 extreme positions of indentation in one-level pars contractilis 211.
Preferably, the junction of described fixed part 20 and one-level pars contractilis 211 is provided with the first sealing member 31, described first close
Sealing 31 is arranged on the inside of fixed part 20 open ports, and is formed with the surface of one-level pars contractilis 211 and be in sealing contact.First seals
Part 31 enters the inside of fixed part 20 and one-level pars contractilis 211 for preventing air-flow.
Preferably, the junction of described one-level pars contractilis 211 and two grades of pars contractilis 212 is provided with the second sealing member 32, described
Second sealing member 32 is arranged on the inside of one-level pars contractilis 211 port, and forms sealing with the surface of two grades of pars contractilis 212 and connect
Touch.Second sealing member 32 enters one-level pars contractilis 211 and the inside of two grades of pars contractilis 212 for preventing air-flow.
The above is embodiment of the present utility model, it is noted that for the ordinary skill in the art,
Without departing under this utility model principle premise, it is also possible to making various deformation and improvement, this also should be considered as this utility model
Protection domain.
