Virgin suction sputum needs that the knocking for carrying out back, the suction sputum in knocking, both sides is coordinated to be carried out at the same time the operation for being unfavorable for doctor, therefore,
How instead of doctor automatically in children's suction sputum knocking children back, facilitate doctor carry out suction sputum operation, become tired
Problem in the industry is disturbed, this is in place of the deficiencies in the prior art.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of medical automatic knocking back sputum aspirator of paediatrics, convenient pair
Back knocking is carried out by the children of suction sputum.
The utility model adopts the following technical solution realizes goal of the invention：
A kind of automatic knocking back sputum aspirator of medical paediatrics, including fixed plate, it is characterized in that：It is fixed in the middle part of the fixed plate
The first rotary shaft is connected, first rotary shaft is hinged the lower end of the upper end and knocking bar of oscillating rod, the lower end of the oscillating rod
One end of the hinged spring of protrusion, the other end of the spring hang over the protrusion at the middle part of the knocking bar, the top of the knocking bar
Portion both sides are fixedly connected with one end of one group of connecting rod, and the other end of the connecting rod is fixedly connected with knocking ball, the fixed plate
Top both sides are fixedly connected with blocking column, and the fixed postlaminar part is hinged the second rotary shaft, and second rotary shaft passes through fixed connect
The output revolving shaft of the catch bar connection stepper motor connect, the stepper motor are fixedly connected with supporting rack, and support frame as described above is fixed on
In the fixed plate, baffle is arranged in the fixed plate bottom, and the baffle is fixedly connected with seat.
As further limiting for the technical program, the catch bar is V-type.
The advantages of prior art is compared, the utility model and good effect are：It allows and the children of suction sputum is wanted to be sitting in fixed plate two
On the seat of side, setting stepper motor is to rotate forward reversing mode, opens stepper motor, and the output revolving shaft of stepper motor passes through fixation
Second rotary shaft of connection drives catch bar to swing back and forth, while the cylindrical protrusions in catch bar branch push knocking bar back and forth
It swings, because the top and bottom of spring are respectively articulated with the protrusion of knocking bar and oscillating rod, under the active force of spring tension, band
Dynamic knocking bar and oscillating rod swing back and forth around the second rotary shaft, and the lower end of oscillating rod is limited when swinging by baffle, is kowtowed
It hits bar to swing back and forth by stopping that column is limited in fixed plate, therefore knocking ball is driven when knocking bar swings back and forth to swing back and forth knocking
Complete back knocking repeatedly in the back of children.The utility model is to be driven with motor by children's knocking back of suction sputum
Apparatus work has liberated the both hands of people, realizes automatic knocking, reliable and stable, and doctor is facilitated to carry out suction sputum operation to children, and
And easy to operate, structure novel, it is of low cost, convenient for universal.

Specific implementation mode
Below in conjunction with the accompanying drawings, a specific implementation mode of the utility model is described in detail, it is to be understood that this
The protection domain of utility model is not restricted by specific implementation.
As Figure 1-Figure 5, the utility model includes fixed plate 3, and 3 middle part of the fixed plate is fixedly connected with the first rotary shaft
8, first rotary shaft 8 is hinged the lower end of the upper end and knocking bar 9 of oscillating rod 6, and the lower end protrusion of the oscillating rod 6 is hinged bullet
One end of spring 7, the other end of the spring 7 hang over the protrusion at the middle part of the knocking bar 9, the top both sides of the knocking bar 9
It is fixedly connected with one end of one group of connecting rod 12, the other end of the connecting rod 12 is fixedly connected with knocking ball 1, the fixed plate 3
Top both sides are fixedly connected with blocking column 10, and 3 rear portion of the fixed plate is hinged the second rotary shaft 13, and second rotary shaft 13 passes through
