Specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with the utility model reality
The attached drawing in example is applied, the technical solutions in the embodiments of the present invention are clearly and completely described.
As shown in Figs 1-4, a kind of switch cabinet shutter link mechanism, including crank mechanism 2, slide block mechanism 4, rocker device 3
With guide rail 7, slide block mechanism 4 includes sliding block 8, and sliding block 8 can be slided up and down along guide rail 7, and slide block mechanism 4 connects valve, thus real
Existing valve is slided up and down along guide rail 7.Crank mechanism 2 is the motive power that slide block mechanism 4 can be driven to drive valve mobile, when
When crank mechanism 2 carrys out back rotation, slide block mechanism 4 can be moved up and down along guide rail 7, to go the on and off of realization valve, be
Increase the mobile stroke of valve, crank mechanism 2 is equipped with the rocker device 3 for being capable of increasing slide block mechanism 4 and valve stroke.It is sliding
Block mechanism 4 and crank mechanism 2 are rotatablely connected by support plate 6;Slide block mechanism 4 and support plate 6 are rotated by being flexibly connected axis 44
Connection, crank mechanism 2 are rotatablely connected by the second concentric shafts 23 with rocker device 3.When crank mechanism 2 gives support plate 6 one
When upward active force, support plate 6 can give 4 one upward power of slide block mechanism so that slide block mechanism 4 moves up,
Since crank mechanism 2 and slide block mechanism 4 are rotatablely connected with support plate 6, under the effect of no rocker device 3,4 energy of slide block mechanism
The furthest travel of arrival, the angle that corresponding support plate 6 is formed with crank mechanism 2 is α, under the action of rocker device 3, really
The degree that angle is α is expanded, so that slide block mechanism 4 can obtain farther stroke.
Rocker device 3 include active plate 31, swivel plate 32 and rocking bar connecting plate 33, the both ends of swivel plate 32 respectively with
Active plate 31 and rocking bar connecting plate 33 are rotatablely connected, and are provided with waist-shaped hole 66 on active plate 31, slide block mechanism 4 passes through
It is flexibly connected axis 44 and increases stroke in sliding up and down for waist-shaped hole 66.Swivel plate 32 is rotated by rotary shaft 45 and support plate 6
Connection, the two sides of rotary shaft 45 are rotatablely connected with connecting plate 31 and rocking bar connecting plate 33 respectively.In rotating crank mechanism 2, rotation
Shaft 45 can also follow the rotation of crank mechanism 2 and rotate,
One end of crank mechanism 2 is rotatablely connected by shaft 5 and rack 1, and 2 other end of crank mechanism passes through the first concentric shafts
22 and second concentric shafts 23 be rotatablely connected respectively with rocker device 3 and mobile support plate 6；Preferably, the first concentric shafts 22
To shaft 5 distance less than the second concentric shafts 23 arrive shaft 5 distance.In order to enable stress is consistent, it is flexibly connected axis 44, second
Isosceles triangle arrangement is presented in concentric shafts 23 and rotary shaft 45, and the distance for being flexibly connected axis 44 to rotary shaft 45 is equal to second with one heart
Axis 23 arrives the distance to rotary shaft 45.For the ease of controlling the rotation of crank mechanism 2, being provided on crank mechanism 2 can control song
The axle sleeve 24 that handle mechanism 2 is rotated around shaft 5, preferably, being provided with two symmetrical axle sleeves 24 on crank mechanism 2.
In the initial state, it is flexibly connected the top that axis 44 is located at waist-shaped hole 66, it is sliding with the rotation of crank mechanism 2
Block mechanism 4 can be moved up under the action of support plate 6, at this time be flexibly connected axis 44 can along waist-shaped hole 66 move downward until
Run to the lowermost end of waist-shaped hole 66, be further continued for rotating crank mechanism 2, at this point, rocker device 3 can stress, in three fulcrums (the
One concentric shafts 22, rotary shaft 45 and the junction for being flexibly connected axis 44 and 66 lowermost end of waist-shaped hole) it can act on simultaneously, so that branch
The angle that fagging 6 and crank mechanism 2 are formed is that α expands, to increase the stroke of slide block mechanism 4.
Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
The range of the utility model protection all should belong in every other embodiment.
