Specific embodiment
The technical solution of the utility model is further elaborated below with reference to examples and drawings.
Embodiment 1
Present embodiments provide a kind of safety cock comprising fixed bracket 5, rotary cylinder 7, active pivoted arm 11, from turn
Arm 10, drive sprocket 4, driven sprocket 3 and support column 2.
The fixed bracket 5 is fixed on device structure 6, and the device structure can be the bed piece of stamping line
Equal components.
The cylinder body of the rotary cylinder 7 is fixed on the fixed bracket 5, and in the present embodiment, the rotary cylinder 7 is band
180 ° of rotary cylinders of limit, and the rotation axis of rotary cylinder is vertically arranged.
One end of the active pivoted arm 11 is rotatablely arranged on the fixed bracket 5 by first rotating shaft, the master
Turn arm 11 is fixed in the first rotating shaft, such as is connected between the active pivoted arm and the first rotating shaft by key
It connects.In the present embodiment, the fixed bracket 5 includes upper bracket and lower bracket, and is existed between the upper bracket and lower bracket
Prepsetting gap;The both ends of the first rotating shaft pass through bearing respectively and are rotatablely arranged in the upper bracket and lower bracket, institute
One end of active pivoted arm 11 is stated between the upper bracket and lower bracket;At this point, the cylinder body of the rotary cylinder 7 also is secured to
On the lower bracket, and the rotation axis of the rotary cylinder 7 and the first rotating shaft are sequentially connected, to work as the rotary cylinder
When 7 work, it is able to drive the first rotating shaft rotation, and at the same time the active pivoted arm 11 is driven to rotate.
One end of the driven pivoted arm 10 is rotatablely arranged at the other end of the active pivoted arm 11 by the second shaft;
