Medically mainly use at present ultrasonic emulsification instrument treatment cataract, by cornea or the scleral incision of 3-5mm size, using ultrasound ripple is pulverized nucleus lentis, makes it be chyle shape, then together with cortex sucking-off.Cataract ultrasonic emulsification is compared with traditional cataract operation mode, and cataract surgery has better surgical effect, has become the most advanced, the reliable cataract therapy method of generally acknowledging in the world at present.
But the display of existing ultrasonic emulsification equipment is generally stationary state, cannot adjusting position, operator can only just can see the information on display in the position limiting, and inconveniently from different positions and visual angle, carry out observation display.
Utility model content
In order to solve above-mentioned practical problem, the purpose of this utility model is to provide a kind of display trunnion axis rotary damping balanced controls, display can be adjusted and rest on optional position, and handled easily personnel are with different view display.
It is as follows that this utility model solves the problems of the technologies described above adopted technical scheme: a kind of display trunnion axis rotary damping balanced controls, comprise the display seat of honour, display bracket, deep groove ball bearing, shaft shoulder screw, described display bracket is two, is symmetrical arranged; The described display seat of honour is in the middle of two display brackets; Described display seat of honour lateral symmetry arranges installation shaft, and described display bracket upper end arranges the installing hole coordinating with installation shaft, and the described display seat of honour is connected on two display brackets by installation shaft, installing hole, deep groove ball bearing, shaft shoulder screw; In described installation shaft, set gradually torsion spring, locking plain cushion, external tooth anti-loosening locking packing ring, wear-resisting lubricated plastic packing ring.
Described installation shaft radially arranges locating piece, and installation shaft center arranges the screwed hole coordinating with shaft shoulder screw;
Described torsion spring is arranged between the display seat of honour and installation shaft locating piece, and torsion spring one end connects the display seat of honour, one end connects display bracket;
Described locking plain cushion arranges groove surface He Tu side;
Described external tooth anti-loosening locking packing ring arranges side with tooth and Fei Ya side;
The groove surface of described locking plain cushion contacts with installation shaft locating piece, the non-tooth side contacts of the protruding side of locking plain cushion and external tooth anti-loosening locking packing ring;
Described wear-resisting lubricated plastic packing ring one side and external tooth anti-loosening locking packing ring side contacts with tooth, a side contacts with display bracket;
In described support installing hole, deep groove ball bearing, jump ring are set;
Described shaft shoulder screw is connected by jump ring, deep groove ball bearing and installation shaft upper screwed hole successively.
Operation principle: when shaft shoulder screw is turned round while putting in place, the end face that counteracting force by locking plain cushion is stung at wear-resisting lubricated plastic packing ring the tooth of external tooth anti-loosening locking packing ring retrains the axial-rotation of wear-resisting lubricated plastic packing ring with this, thereby make wear-resisting lubricated plastic packing ring and display bracket remain close contact, the display seat of honour when rotated, by the frictional force between display bracket and wear-resisting lubricated plastic packing ring, the torsion of torsion spring is realized damping balance motion, the display seat of honour can be rotated to optional position and stop, display is arranged on the display seat of honour, thereby make display rotate arbitrarily and to stop.
Beneficial effect: this utility model is simple in structure, running is steady, can allow display rotation rest on optional position, and handled easily personnel are with different visual angles observation display.
