Title:
CONNECTING APPARATUS FOR OIL CYLINDER AND SLIDING BLOCK
Document Type and Number:
WIPO Patent Application WO/2016/201883
Kind Code:
A1
Abstract:
A connecting apparatus for an oil cylinder (1) and a sliding block (4). The connecting apparatus for an oil cylinder (1) and a sliding block (4) comprises an oil cylinder (1), a piston rod (2), a spherical washer (3), a sliding block (4), and a connecting mechanism, wherein the piston rod (2) is a part of the oil cylinder (1); the spherical washer (3) is disposed between the piston rod (2) and the sliding block (4); and the connecting mechanism connects the oil cylinder (1) and the sliding block (4) by means of the piston rod (2). The connecting mechanism comprises a pin shaft (5), square pins (6), and connecting bolts (7). The connecting apparatus for an oil cylinder and a sliding block adopts four connecting bolts and two square pins. Compared with a connecting apparatus adopting a single thick screw rod or two bolts plus a pin shaft, the connecting apparatus reduces the stress on a single bolt, and reduces the processing difficulty and cost of the connecting mechanism.
