Sliding slot 311 is extended with certain length along the glide direction of sliding block 30, slides eccentric shaft 51 in sliding slot 311, to drive
Movable slider 30 can slide in slideway 14 along the extending direction of slideway 14.It should be noted that the extending direction of sliding slot 311 with
The direction of motion of sliding block 30 be it is orthogonal, when horizontally slipping in 51 sliding slot 311 of eccentric shaft, also drive sliding block 30 in cunning
It is slided up and down in road 13.
Referring to Fig. 2, in an embodiment of the present invention, the only liquid device 100 further includes axle sleeve 90, and the axle sleeve 90 is arranged
In the eccentric shaft 51, the lateral wall of the axle sleeve 90 is abutted with 311 side wall of sliding slot.
In the scheme of the embodiment of the present invention, the sleeve-shaped that axle sleeve 90 is connected in both ends, and the internal diameter of axle sleeve 90 and bias
The outer diameter of axis 51 matches.Axle sleeve 90 is set in the end of eccentric shaft 51, when eccentric wheel 50 drives sliding block 30 to slide, axle sleeve 90
Lateral wall is abutted with 311 side wall of sliding slot, and the sliding friction of former eccentric shaft 51 and 311 side wall of sliding slot is converted into rolling friction, is subtracted
The frictional resistance of small eccentricity axis 51 and sliding block 30.
Referring to Fig. 4, in an embodiment of the present invention, the bottom wall of the slideway 14 is also provided with holding tank 15, the bias
Wheel 50 is rotatably set in the holding tank 15.
In the scheme of the embodiment of the present invention, holding tank 15 is arranged by the bottom wall in slideway 14 and is used to place eccentric wheel 50,
In this way, the installation space of eccentric wheel 50 can be saved by eccentric wheel 50 directly in the inside of mounting base 10, to make only liquid dress
Set 100 the occupied space of entirety it is small.
Referring to Figure 2 to Figure 4 and Fig. 6, in an embodiment of the present invention, the eccentric wheel 50 is towards 15 bottom wall of holding tank
Surface be also recessed with connecting hole 53, the only liquid device 100 further includes motor 70, and the motor 70 is installed on the mounting base
10 bottom outside, the output shaft 71 of the motor 70 run through the bottom wall of the holding tank 15 and are inserted in connecting hole 53, with
The eccentric wheel 50 is driven to rotate.
In the scheme of the embodiment of the present invention, only liquid device 100 is driven by motor 70, and motor 70 is set to the outer of mounting base 10
The output shaft 71 of side, motor 70 is connect with eccentric wheel 50.Specifically, defeated for power supply machine 70 in offering for 15 bottom wall of holding tank
Pass through 153 mouthfuls of resigning button of shaft 71, eccentric wheel 50 is also recessed with connecting hole 53, motor 70 towards the surface of 15 bottom wall of holding tank
Output shaft 71 pass through connection and step down 153 mouthfuls of button, and be inserted in connecting hole 53,70 output shaft 71 of motor rotation, to drive
Inner rotation of the eccentric wheel 50 in holding tank 15.In the present embodiment, connecting hole 53 is arranged to D profile shaft hole, accordingly, output shaft 71
Be also provided with into shape compatible with D profile shaft hole, so set, can be prevent it is mutual between output shaft 71 and eccentric wheel 50
Sliding, it is ensured that the stability that 70 output shaft 71 of motor is connect with eccentric wheel 50.Eccentric wheel 50 is driven to rotate using motor 70
Mode convenient for control sliding block 30 direction, it is only necessary to control motor 70 rotate and reverse can be achieved with driving sliding block 30 towards or
Away from peace pipeline 20 move, in order to liquid in pipeline 20 circulation or disconnect easily controlled.
It should be noted that motor 70 is positive and negative rotation of the control panel (not shown) to motor 70 by connecting with motor 70
It is controlled.Specifically, control panel can also detect 70 current value of motor, and after motor 70 is powered, output shaft 71 is just
Turn, output shaft 71 drives sliding block 30 to move towards the pipeline 20 in pipeline installation passage 13 by eccentric wheel 50, when sliding block 30 will
After pipeline 20 compresses, sliding block 30 cannot be further continued for moving, at this point, the electric current by motor 70 increases, control panel detects motor
70 electric current raising reaches certain value, and control motor 70 stops rotating movement, at this point, sliding block 30 is in the shape of the pipeline 20 of compression
State, the liquid in pipeline 20 are blocked flowing, to have achieved the purpose that only liquid.It is defeated when the reversion of 70 energization rear output shaft 71 of motor
Shaft 71 drives sliding block 30 to move far from pipeline installation passage 13 by eccentric wheel 50, when sliding block 30 is connected to deviating from for slideway 13
When the side wall of pipeline installation passage 13, sliding block 30 cannot be further continued for moving, at this point, the electric current by motor 70 increases, control panel
Detect that the electric current raising of motor 70 reaches certain value, control motor 70 stops rotating movement, at this point, sliding block 30 is in pipeline
20 states loosened, the state that the liquid in pipeline 20 is on.
Referring to Figure 2 to Figure 4, in an embodiment of the present invention, 15 bottom wall of holding tank is equipped with mounting hole 155, the electricity
Machine 70 is equipped with fixation hole 73 towards the surface of 10 bottom of mounting base, and the motor 70 passes through the connector and the installation
The mounting base 10 is fixed in the cooperation of hole 155 and the fixation hole 73.
In the scheme of the embodiment of the present invention, motor 70 is connect with mounting base 10 by connector.Specifically, connector can be with
It is screw, in this way, the fixation hole 73 on surface of the motor 70 towards 10 bottom of mounting base is threaded hole, the mode connected using screw
It can guarantee the fastness that the motor 70 of connection is connect with mounting base 10.It is understood that connector can also be pin or
Bolt, it is numerous to list herein as long as being able to achieve being fixedly connected between motor 70 and mounting base 10.
Referring to Fig. 4, in an embodiment of the present invention, the side wall positioned at 14 side of slideway of the holding tank 15 is also convex
Equipped with limit rib 151, the limit rib 151 is extended along the depth direction of the holding tank 15, and the limit rib 151 deviates from
The end of 15 bottom wall of holding tank is abutted with the sliding block 30.
In the scheme of the embodiment of the present invention, the limit rib 151 of the side wall projection of holding tank 15 is used to support sliding block 30, avoids
There is the case where sinking towards holding tank 15 during sliding in sliding block 30, influences the stationarity of the sliding of sliding block 30, limit rib 151
Away from the surface of the end abutment sliding block 30 of 15 bottom wall of holding tank, it is ensured that sliding block 30 can in slideway 14 held stationary sliding,
To ensure the effect of the extruding to pipeline 20.It should be noted that limit rib 151 extends along the depth direction of holding tank 15
Setting, so set, facilitating the demoulding in the production process of mounting base 10 when mounting base 10 is injection molding.Further, it limits
Position muscle 151 can be spaced multiple, so may further ensure that the stationarity of sliding block 30.
Referring to Fig. 5, in an embodiment of the present invention, the sliding block 30 includes slider body 31 and press section 33, the cunning
Block body 31 is slidingly disposed in the slideway 14, the press section 33 be convexly equipped in the slider body 31 towards the pipe
The surface of road installation passage 13；When the sliding block 30 is moved toward and away from the pipeline 20 for being installed on the pipeline installation passage 13
When, the press section 33 compresses away from the end of the slider body 31 or loosens the pipeline 20.
In the scheme of the embodiment of the present invention, slider body 31 is substantially square, and slightly narrower than the width of slideway 14, sliding slot
311 be set to slider body 31, the setting of 33 strip of press section, and deviate from slider body 31 the tapered setting in end, so as to
In squeezing pipeline 20, in this way, the whole volume of sliding block 30 reduces.Also, when eccentric wheel 50 connect and drives with slider body 31
When movable slider 30 slides, as long as enabling the end of press section 33 to squeeze pipeline 20, in this way, sliding block 30 can also be reduced
Sliding distance.
