In preferred embodiment, in described only liquid pedestal, open up the space holding described liquid stopping clamp and rotate, and the bottom surface of described only liquid pedestal and side are unlimited to ensure that described liquid stopping clamp can freely rotate.
In preferred embodiment, described pipeline groove is U-lag, and be arranged on described only liquid pedestal end face.
In preferred embodiment, a side of described only liquid pedestal is also provided with sliding eye vertically downward.
In preferred embodiment, described only liquid pedestal is also provided with self-lock rod, and described self-lock rod is L-type, and one end of described self-lock rod is through described sliding eye, and the other end is arranged in the side of described pipeline groove, and described self-lock rod can slide up and down in described sliding eye.
In preferred embodiment, described liquid stopping clamp comprises self-locking side and stops liquid side, described self-locking side and only liquid side be arranged in parallel and one-body molded by connecting portion, be also provided with the transverse axis connecting self-locking side and only liquid side above described connecting portion, described transverse axis be arranged with torsion spring.
In preferred embodiment, described self-locking side offers outwardly open locating slot, and the peristome of described locating slot tilts slightly upward.
In preferred embodiment, described only liquid side is roughly square.
In preferred embodiment, a reverse arm of described torsion spring and described connecting portion offset, and another reverse arm and described self-lock rod offset.
In preferred embodiment, the end face of described only liquid pedestal is provided with the breach holding described only liquid side and self-locking side, described when only liquid side turns over described breach, described pipeline groove can be closed, to reach the object of only liquid.
The beneficial effects of the utility model are: when needs stop liquid, press self-lock rod, make self-lock rod be in the locating slot of self-locking side, and now liquid stopping clamp is along rotating clockwise under the pulling force of extension spring, makes only liquid side close pipeline groove, to reach the object of only liquid.When liquid stopping clamp opened by needs, only need to stir liquid stopping clamp counterclockwise, now under the restoring force of torsion spring, self-lock rod is pushed out locating slot, and liquid stopping clamp is blocked can not rotate by self-lock rod, also just can not close pipeline groove.Total is simple to operate, and when not needing to stop liquid, can automatically locking the state for opening, need not take out tube for transfusion, very convenient.

Detailed description of the invention
Below in conjunction with accompanying drawing, describe wherein a kind of detailed description of the invention of the present utility model in detail.
Consult Fig. 1, a kind of infusion pump stops liquid device, comprise only liquid pedestal 1, liquid stopping clamp 2, rotating shaft 3, extension spring 4 and extension spring holder 5, described only liquid pedestal 1 is connected with described liquid stopping clamp 2 by rotating shaft 3, one end of liquid stopping clamp 2 is connected with described extension spring 4 one end, and the other end of extension spring 4 is connected with described extension spring holder 5, and wherein said only liquid pedestal 1 is provided with the pipeline groove 11 settling infusion pipeline, described liquid stopping clamp 2 can close described pipeline groove 11 by rotation, to reach the object of only liquid.
Consult Fig. 2 in the lump, described liquid stopping clamp 2 is inclusive in described only liquid pedestal 1 inside, open up the space holding described liquid stopping clamp 2 and rotate in described only liquid pedestal 1, and the bottom surface of described only liquid pedestal 1 and side are unlimited to ensure that described liquid stopping clamp 2 can freely rotate.
Described pipeline groove 11 is U-type groove, is used for placing infusion pipeline, and pipeline groove 11 is arranged on the end face of only liquid pedestal 1.
A side of described only liquid pedestal 1 is also provided with sliding eye 12 vertically downward.Described only liquid pedestal 1 is also provided with self-lock rod 13, and described self-lock rod is L-type, and one end of described self-lock rod 13 is through described sliding eye 12, and the other end is arranged in the side of described pipeline groove 11, and described self-lock rod 13 can slide up and down in described sliding eye 12.
Described liquid stopping clamp 2 comprises self-locking side 21 and stops liquid side 22, described self-locking side 21 and only liquid side 22 be arranged in parallel and one-body molded by connecting portion 23, also be provided with the transverse axis 24 connecting self-locking side and stop liquid side above described connecting portion 23, described transverse axis be arranged with torsion spring 25.
On described self-locking side, 21 offer outwardly open locating slot 211, and the peristome of described locating slot tilts slightly upward.
Described only liquid side 22 is roughly square.
When installation, a reverse arm 251 and the described connecting portion 23 of described torsion spring 25 offset, and another reverse arm 252 is positioned at the below of described self-lock rod 13 and vertically offsets with it.
The end face of described only liquid pedestal 1 is provided with the breach holding described only liquid side 22 and self-locking side 21, described when only liquid side 22 turns over described breach, described pipeline groove can be closed, to reach the object of only liquid.
It should be noted that, when installation should stop liquid device, cooperatively interact between described self-lock rod 13, locating slot 211 and torsion spring 25 and realize this only state of being out of liquid device of locking, for arriving this purpose, locating slot 211 opening on liquid stopping clamp 2 is acclivitous, and the initial position of described self-lock rod 13 is just positioned at the upper edge of the opening part of locating slot 211, in an initial condition, self-lock rod 13 blocks liquid stopping clamp 2 and stops it to rotate.
Below in conjunction with accompanying drawing 3, illustrate that this infusion pump stops the operation principle of liquid device: in an initial condition, stop it to rotate because self-lock rod 13 blocks liquid stopping clamp 2, stop the state that liquid device is out, now only liquid device can use as tubing clamp.When needs stop liquid, stir self-lock rod 13 downwards, now self-lock rod 13 is to the reverse arm 252 pressing down torsion spring 25, self-lock rod 13 aims at locating slot 211, all the time the trend that the pulling force effect and keeping being subject to extension spring 4 due to liquid stopping clamp rotates clockwise, and the position of self-lock rod 13 moves down in locating slot 211 and can not continue to stop liquid stopping clamp to rotate, only the only liquid side 22 of liquid folder 2 closes pipeline groove 11, compresses the object that infusion pipeline reaches only liquid.
