Described top plate, ratchet and bottom plate is connected for fixing with described bearing pin.
In the damping unit that four groups of described structures are identical, first group of mesosphere board connects handle by connecting what bearing pin can rotate Being connected between second group of top plate and the connection handle of bottom plate, the connection handle of second group of mesosphere board is by connecting bearing pin energy Enough rotate be connected to the 3rd group between top plate and the connection handle of bottom plate, the connection handle of the 3rd group of mesosphere board is by even What pin axle can rotate be connected to the 4th group between top plate and the connection handle of bottom plate, the connection handle of the 4th group of mesosphere board Hands is connected between first group of top plate and the connection handle of bottom plate by what connection bearing pin can rotate.
The maximum angle that the connection handle of described top plate, mesosphere board and bottom plate rotates against is 60 degree.
Described ratchet is provided with the gear teeth of more than 5.
The diameter of described roller is more than or equal to the distance between gear teeth nook and the described extruding lead inner side edge of ratchet.
Described roller uses steel cylindrical roller.
Described extruding lead uses machining lead.
Described top plate and bottom plate are provided with non-cohesive material layer between the contact surface of described mesosphere board.
Described helical spring is arranged on the nook of the gear teeth on described ratchet.
A kind of two dimension spacing-type lead extrusion damper of the present invention, is arranged in building structure as dissipative cell, and displacement dimension increases Add, can realize alone being subjected to displacement in two-dimensional space.Having limit function, roller is only in the scope of ratchet gear teeth Motion, the maximum angle that corresponding handle can be turned through is 60 degree, reaches limit function.There is certain initial stiffness and can resist wind Load and little shake effect, when exceeding fortification intensity, this dissipative cell enters duty, dissipation seismic energy.The present invention can It is widely used in the energy-dissipating and shock-absorbing of building and spacing control.
