The schematic diagram of 100 different visual angles of shaft type rotary damper of utility model.Referring to Fig. 1, the axis of the embodiments of the present invention
Formula rotary damper 100 includes shell 10, mandrel 20 and damping oil 30, and mandrel 20 is located in shell 10, shell 10 and mandrel 20
Between be formed with a storage chamber 40, damping oil 30 is stored in storage chamber 40, mandrel 20 be suspended in damping oil 30 and and shell
It is relatively rotated between 10.It is stored with damping oil 30 between shell 10 and mandrel 20, due to the viscosity property of damping oil 30, makes
The damping oil 30 that must be attached between shell 10 and mandrel 20 is sheared tearing, this destroys the tearing of 30 stability characteristic (quality) of damping oil
Power forms the resistance of damper, during hinge rotates, plays the role of slew buffer, can effectively avoid hinge and frame
The hard collision of frame, the effective service life for increasing hinge.
Further, the various pieces of the present embodiment central-axis type rotary damper 100 are described in detail：
Wherein, referring to Fig. 1, in the horizontal direction from left to right (according to Fig. 1 reality on the inside of 10 left end of shell of the present embodiment
Direction) it is extended with a positioning column 11, mandrel 20 is sheathed on positioning column 11, and one is formed with close to 20 one end of mandrel of positioning column 11
First positioning groove 21, positioning column 11 are set in the first positioning groove 21.Preferably, positioning column 11 be cylinder, then correspondingly,
Preferably, the first positioning groove 21 is also cylinder shape groove, and the radial diameter of the first positioning groove 21 is slightly larger than positioning column 11
Radial diameter, be inserted into the first positioning groove 21 convenient for positioning column 11 in this way.But the radial diameter of the first positioning groove 21
It is more that it is not preferably greater than 11 radial diameter of positioning column, mandrel 20 is avoided radially to be shaken in shell 10.
