Specific embodiment
Below in conjunction with preferred embodiment and its accompanying drawing to a kind of syringe pump syringe clamping device according to the present invention
Technical scheme is further non-limitingly described in detail.
Refer to Fig. 1, shown in 2, an embodiment of the invention provides a kind of syringe pump syringe clamping device,
It includes short axle 1, pressing plate 2, short set 3, major axis 4, coupling sleeve 5, potentiometer 6, wiring board 7, fixed mount 8, spring 9,10, length of having strong market potential
Bar 11, short pin 12, housing 13.Wherein, described stock 11, short set 3, short pin 12 composition member structure, described short axle 1, major axis 4,
Coupling sleeve 5, the shafting structure of the rotary shaft composition of potentiometer 6.
Further, 6 parts such as described short axle 1, pressing plate 2, short set 3, major axis 4, coupling sleeve 5, potentiometer 6 are co-axially mounted
On housing 13, described wiring board 7 is fixed on described potentiometer 6, and described stock 11 passes through described short pin 12 with described short set 3
It is assembled together, described stock 11 can be freely rotatable around described short pin 12, and described fixed mount 8 is fixed on described housing 13, institute
State spring 9 to be arranged in the circular hole of described stock 11, simultaneously described have strong market potential 10 to pass through described stock 11 to compress described in circular hole
Spring 9, described having strong market potential 10 is fixedly mounted on described fixed mount 8.Now described stock 11 makes institute under the thrust of described spring 9
State short set 3 and be maintained at initial position, and then make entirely coaxial mounted shafting structure be maintained at initial bit by described short set 3
Put.
Refer to shown in Fig. 3, during use, pressing plate 2 described in Unscrew, described pressing plate 2 drives described short axle 1, major axis 4 same
Step rotates, and described major axis 4 drives described short set 3 around axis rotation, the described stock 11 being connected with short set 3 by described short pin 12
Around 10 rotations of having strong market potential being fixed on described fixed mount 8, the described spring 9 being now arranged on described stock 11 in the hole is further
Compression, after described stock 11 turns over the dead point with described short set 3, described short set 3 is limited by the limit rib 81 on described fixed mount 8
System, now, in the presence of described spring 9 compresses described stock 11, whole shafting structure is in self-locking state, now can so that
In the prompt groove placing a syringe in described housing 13 opposite side.
Refer to shown in Fig. 4, after described syringe 20 places, stir described pressing plate 2, described short set 3 is crossed and institute
After stating the dead point of member structure of stock 11 composition, under the thrust of described spring 9 acts on, described stock 11 is to described short set
The 3 certain torques of applying, so that described major axis 4, short axle 1, coupling sleeve 5, the rotary shaft of potentiometer 6 are maintained at fixing position.
Now, because the arm of force of described pressing plate 2 short set 3 more described with the arm of force of described syringe 20 application point is long, therefore the pressure of described spring 9
