Abstract
The utility model belongs to the field of medical apparatus and discloses a resistance type triaxial four-connecting rod lifting rotary platform in order to arrange a workbench which is convenient to operate and saves space on an ultrasonic emulsification device. The resistance type triaxial four-connecting rod lifting rotary platform comprises the workbench, a first connecting shaft, a four-connecting rod mechanism, a second connecting shaft and a third connecting shaft, wherein the upper end of the first connecting shaft is connected with the workbench; the lower end of the first connecting shaft is connected with the front end of the four-connecting rod mechanism; the rear end of the four-connecting rod is connected with the upper end of the second connecting shaft; the lower end of the second connecting shaft is connected with the front end of a connecting and supporting piece; the rear end of the connecting and supporting piece is connected with the upper end of the third connecting shaft. The resistance type triaxial four-connecting rod lifting rotary platform has the advantages that the use is convenient, the space is saved, the platform can be folded when not in use, objects can be placed on the workbench which is unfolded when in use, and the angle and height of the workbench can be adjusted by operators according to need during working.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly ultrasonic emulsification equipment.
Background technology
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 do not place the workbench of operational tool on existing ultrasonic emulsification equipment, when doctor performs an operation to patient, the general Operation trolley that uses is placed various operational tool, but Operation trolley relatively takes up space, and it is not very convenient using.
Utility model content
The purpose of this utility model is to provide a kind of can being accommodated in super newborn equipment, can conveniently launch and need to adjust according to operator the workbench of the placement operational tool of angle and height during use.
It is as follows that this utility model solves the problems of the technologies described above adopted technical scheme: a kind of resistance type three axle four connecting rods are stretched and fallen rotation platform, comprise workbench, the first connecting axle, quadric chain, the second connecting axle, the 3rd connecting axle, described the first connecting axle upper end is connected with workbench, the first connecting axle lower end is connected with quadric chain front end, described quadric chain rear end is connected with the second connecting axle upper end, described the second connecting axle lower end be connected support member front end and connect, described connection support member rear end is connected with the 3rd connecting axle upper end.
On described first, second, third connecting axle, be provided with plane roller bearing, bearing holder (housing, cover), locking nut;
Described the 3rd connecting axle lower end is fixed in work box by connection bearing part;
Described quadric chain is provided with two movable axis, two fixed axis, two supports, upper backup pad, lower link, cylinder, cylinder fixed axis;
Between described two movable axis, by upper backup pad, connected;
Between described two fixed axis, by lower link, connected;
Described upper backup pad is identical with lower link length;
Between the movable axis of described the same side and fixed axis, by support, be connected;
Described cylinder one end is fixed on upper backup pad below by cylinder fixed axis, and the other end is connected with the fixed axis near the second connecting axle.
Three connecting shaft operation principles: three connecting axles can 360 deg rotation, but in the locking situation of locking nut and connecting axle, also have certain drag effect during around the rotation of axle between connector, so need to change angle along with oneself when work.
Quadric chain operation principle: quadric chain is a parallelogram, when opening, cylinder can elongate or shorten, while closing, keep length constant, when workbench need to change height, open cylinder, the flexible drive upper backup pad of cylinder tilts mobile, parallelogramming deflection is tilted, before and after distortion, produce a difference in height, thereby change bench height, after changing to suitable height, shifter cylinder, cylinder can keep length constant, quadric chain locking position, akinesia, thus stationary work-table is at the height of needs.
Beneficial effect: this utility model is easy to use, saves space, after can folding, accepts in the time of no, launches on workbench, to put thing during use, can be according to the angle that need to adjust workbench of oneself and height when operator work.

The specific embodiment
Below in conjunction with accompanying drawing, this utility model is further illustrated.As shown in Figure 1,2,3, 4, a kind of resistance type three axle four connecting rods are stretched and are fallen rotation platform, comprise workbench 1, the first connecting axle 2, quadric chain 3, the second connecting axle 4, the 3rd connecting axle 5, described the first connecting axle 2 upper ends are connected with workbench 1, the first connecting axle 2 lower ends are connected with quadric chain 3 front ends, described quadric chain 3 rear ends are connected with the second connecting axle 4 upper ends, described the second connecting axle 4 lower ends be connected support member 6 front ends and connect, described connection support member 6 rear ends are connected with the 3rd connecting axle 5 upper ends.
On described first, second, third connecting axle 2,4,5, be provided with plane roller bearing 7, bearing holder (housing, cover) 8, locking nut 9;
Described the 3rd connecting axle 5 lower ends are fixed in work box 11 by connection bearing part 10;
Described quadric chain 3 is provided with two movable axis 31, two fixed axis 32, two supports 33, upper backup pad 34, lower link 35, cylinder 36; Cylinder fixed axis 37;
Between described two movable axis 31, by upper backup pad 34, connected;
Between described two fixed axis 32, by lower link 35, connected;
