Limitation.
A kind of link mechanism that the safety cover plate convenient for wind-driven generator opens and closes, safety cover plate 1 are embedded in sliding slot 2,
It 2 rectilinear directions can horizontally slip along the chute under external force；The side of safety cover plate 1 is bolted in Ω type
Handle 3 directly can pull handle 3 with hand when necessary and open safety cover plate 1.
3 top of handle is fixed with L-shaped connector 4 via bolt, and the top of connector is connected by the first articulated section 6
Drag link 5, the end of Drag link 5 connect curved pull rod 7 by the second articulated section 8, curved pull rod 7 via security platform 133 gap
Middle stretching；7 middle and upper part of curved pull rod is articulated with the side of security platform 13 by third articulated section 10；The top of curved pull rod 7 passes through
Bolt is fixed with force handle 12；The handle 12 that exerts a force is in Y type, and the top of curved pull rod 7 is fixed on by cross screw bolt 1201.Connection
Body 4, Drag link 5, curved pull rod 7, force handle 12 4 form mechanical linkage, and force handle 12 is designed into cabin security platform
On 13, arc swinging is done using curved pull rod 7, easily closes safety cover plate 1.
The rear portion of force handle 12 is provided with detachable casing 14, and force handle 12 is inserted in 14 bottom end of casing when use
On, enlarging moment, folding safety cover plate 1 that can be more laborsaving.After safety cover plate 1 is closed, removes casing 14 and places at regulation,
Since the torque of force handle 12 itself is shorter, it can prevent staff from accidentally touching and open safety cover plate 1, cause accident.
10 side of third articulated section of security platform 13 is fixed with the indicator board 11 with graduation mark；By the way that indicator board is arranged
11, the scale at indicator board 11 is located at according to curved pull rod 7, can indirectly obtain the folding size of security platform 13, is not had to curved
Waist is bowed from gap, and use is more flexibly safe.
In addition to this, the front side at 1 closure of safety cover plate is equipped with the latch segment 9 in groove, when 1 closing of safety cover plate
Afterwards, the second articulated section 8 of Drag link 5 and curved pull rod 7 is protruded into just in the groove at 9 top of latch segment, and 9 band of latch segment is magnetic,
The second articulated section 8 of ferrous material is adsorbed, when latch segment 9 adsorbs the second articulated section 8, clear and melodious sound can be issued, remind work
Make personnel to close in place；Simultaneously as latch segment 9 has magnetic force, there is certain locking effect to safety cover plate 1, be safety
Performance is higher.
The utility model production when, it should be noted that accurately to determine connector 4, Drag link 5, curved pull rod 7,
Exert a force the size of handle 12, and whether the space length that the above-mentioned each swing arm of when operation needs to do arcuate movement needs is enough, if energy
Normally not by the light folding safety cover plate 1 of resistance.When safety cover plate 1 is closed, the fixing lock at the dead point of the second articulated section 8
Tight block 9.
Although the various embodiments described above are described, once a person skilled in the art knows basic wounds
The property made concept, then additional changes and modifications can be made to these embodiments, so the above is only the embodiments of the present invention,
It is not intended to limit the scope of patent protection of the utility model, it is made by using the description of the utility model and the drawings
Equivalent structure or equivalent flow shift is applied directly or indirectly in other relevant technical fields, and is similarly included in this reality
Within novel scope of patent protection.
