Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, 2, the present invention provides a kind of link mechanism comprising: connecting rod rack 1, hypophysis component 2, compression bullet
Spring 3, rope sheave 4.
The connecting rod rack 1 is for connecting two hypophysis components 2, and specifically, the connecting rod rack 1 is able to carry out pivot fortune
Dynamic, the connecting rod rack 1 is to pass perpendicularly through the axis of center as shaft.Meanwhile connection is offered on the connecting rod rack 1 and is hung down
The kidney slot 11 of body component 2.Preferably, the kidney slot 11 is two, and two kidney slots 11 are in center pair around the center
Claim distribution.In addition, the circumferential edges holding of the relatively described connecting rod rack 1 of any kidney slot 11 is obliquely installed.
The hypophysis component 2 is used in 4 high speed rotation of rope sheave, does centrifugal movement, when it reaches trigger position, can be touched
Electrical action and pawl action are sent out, realizes braking.In two hypophysis components 2, any hypophysis component 2 include: hypophysis 21,
The pin shaft 22 being connected on the hypophysis 21.
Wherein, in any hypophysis component 2, the hypophysis 21 is a cylindrical body pouring weight, in order to when rotating at high speed,
Hypophysis 21 can be thrown out of.The hypophysis 21 is connected in the kidney slot 11 accordingly slidingly by its pin shaft 22.In addition, being
It is slided convenient for hypophysis component 2 along the kidney slot 11, in any hypophysis component 2, is also set on the pin shaft 22
The deep groove ball bearing for thering is an auxiliary pin shaft 22 to slide along the kidney slot 11.
The compressed spring 3 is for guaranteeing moving synchronously for two hypophysis components 2.Specifically, the compressed spring 3 is set with
In on a rod piece 5, being further sleeved with a fixing gasket 6 on the rod piece 5, the fixing gasket 6 is located at the one of the compressed spring 3
End.Meanwhile the edge of the connecting rod rack 1 has gap, the fixing gasket 6 extends in the gap.To when even
When bar bracket 1 is together with hypophysis 2 high speed rotation of component thereon, it is opposite that one is generated with the compressed spring 3 and fixing gasket 6
Angular speed, 6 compressible spring 3 of fixing gasket, makes spring-compressed at this time, keeps hypophysis component 2 slowly mobile, it is ensured that two hypophysis
The synchronism of component 2.
The rope sheave 4 for being bypassed for wirerope, and provide the connecting rod rack 1, hypophysis component 2, compressed spring 3 peace
Dress basis.Specifically, the rope sheave 4 includes: annulus 41 and the cross reinforcing rib 42 that is connected to inside the annulus 41.Its
In, the center of the connecting rod rack 1 is pivotally connected to the crossover location of the cross reinforcing rib 42.
The pivoting action of the connecting rod rack 1 for convenience leads between the connecting rod rack 1 and the cross reinforcing rib 42
Ball bearing is crossed to be connected.Meanwhile the sliding slot 421 of two center symmetric settings, institute are also provided on the cross reinforcing rib 42
Hypophysis component 2 is stated to be slidingly arranged in corresponding sliding slot 421.
Further, the fixing gasket 6 is fixedly arranged on the cross reinforcing rib 42, the sliding slot and the kidney slot 11
Between have an angle, when such hypophysis component 2 does centrifugal movement, kidney slot 11 straight line of the hypophysis component 2 on connecting rod rack 1
Mobile, two hypophysis components 2 apply active force to connecting rod rack 1, rotate connecting rod rack 1 under the active force of two hypophysis components 2,
And opposite rope sheave 4 generates an opposite angular speed.At this point, gap on the connecting rod rack 1 can with 6 phase separation of fixing gasket,
Make spring-compressed, it is slowly mobile to keep hypophysis component 2, and trigger electric switch and pawl action.
In conclusion link mechanism of the invention connects two hypophysis components by connecting rod rack, and pass through compressed spring
It is further ensured that the synchronism of hypophysis component movement, structure is simple, and synchronism is good, and cost is relatively low.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
