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； The driven pivoted arm 10 is fixedly connected with second shaft, such as passes through key between the driven pivoted arm and second shaft It is attached；In the present embodiment, the first rotating shaft and the second shaft are vertically arranged.

The drive sprocket 4 is fixed on the fixed bracket 5, more specifically, the drive sprocket 4 can be fixed on institute On the upper bracket for stating fixed bracket 5, and the drive sprocket 4 is coaxially disposed with first rotating shaft.

The driven sprocket 3 is fixed in second shaft, and driven sprocket 3 is coaxially set with second shaft It sets, is sequentially connected between the drive sprocket 4 and driven sprocket 3 by chain 12, and the number of teeth of drive sprocket and driven sprocket Than for 1:2.

The support column 2 is fixedly mounted on the other end of the driven pivoted arm 10, and the support column is vertically arranged, in institute When stating the rotation of driven pivoted arm, support column is enabled to be moved between stationary work-table 8 and movable part 1 from a position, from And the danger for preventing movable part 1 from falling suddenly and occurring.

The safety cock of the utility model when in use, controls 180 ° of rotary cylinders by pneumatic pilot line and makees rotation fortune It is dynamic, and drive active pivoted arm 11 to rotate, while because drive sprocket 4 and fixed bracket 5 are fixed, drive sprocket 4 passes through chain Transmission drives driven sprocket 3 and driven pivoted arm 10 to rotate, because gear ratio is 1:2, therefore when active pivoted arm 12 rotates 180 °, from Turn arm 10 rotates 90 ° relative to from rotation axis, and in the pneumatic pilot line, can realize gas by solenoid valve Road switching, realizes automation.
