Transmission properties of temporal inactive joints (TIJ) in multi linkage mechanisms were studied by analysing the self locking performance of 4 bar and 6 bar linkages using TIJ concept.
为推导多杆机构的瞬停节传递特性，利用瞬停节的概念分析了4杆机构和6杆机构的自锁性能。

The unique lockingbar system prevents the key on the output shaft from tipping in the keyway, eliminating the possibility for key and keyway damage that results in a loss of productivity.
Lockingbar system, for heavy doors the rod is supplied undivided. Both ends can be connected to the gear mechanism. This allows any positioning of the gear casing.
