Abstract
The utility model relates to a liquid transferring device, which comprises an air sac and a liquid guide pipe. The liquid transferring device is characterized in that the air sac and the liquid guide pipe are fixed into a whole by a device body; a suction pipe clamp is arranged on the liquid suction end of the liquid guide pipe, the other end of the liquid guide pipe is connected with the air sac, and the connecting position of the liquid guide pipe and the air sac is sealed and fixedly connected. A release spring is arranged on the periphery of the air sac, and is connected with a plunger.
Description
The utility model relates to a kind of chemical industry apparatus, i.e. pipettor.
At present, use suction pipe because of must bimanualness in its use very inconvenient, especially for chemical reaction than process faster, then feel in a rush and join and be too busy, even affect course of reaction adversely, cause failure, cause time and raw-material waste.
Its purpose of the utility model is: a kind of pipettor is provided, and it is provided with suction pipe folder suction pipe is fixed, and can one hand conveniently do and move liquid work, and another hand can be done its usefulness, and also convenient and strength-saving.
The utility model is achieved in that a kind of pipettor comprises: air bag, catheter is characterized in that: its air bag, catheter are solidified as a whole by body; The imbibition end of its catheter is provided with the suction pipe folder, and one end in addition links to each other with air bag, and its interface sealing also is fixedly connected; Its air bag periphery is provided with retracing spring and links to each other with plunger.
Elaborate below in conjunction with embodiment and accompanying drawing:
Fig. 1: the utility model structural representation
Its structure of the utility model pipettor is as shown in Figure 1: comprise air bag (4), catheter (2), it is characterized in that: its air bag (4), catheter (2) are solidified as a whole by body (1); The imbibition end of its catheter (2) is provided with suction pipe folder (3), and one end in addition links to each other with air bag (4), and its interface (24) seals and is fixedly connected; Its air bag (4) periphery is provided with retracing spring (41) and links to each other with plunger (43).
Its suction pipe folder (3) inwall and annulus (32) are fixedly connected, and its annulus (32) is solidified as a whole with arc spring leaf (31) one ends, its suction pipe folder (3) and body (1) thread connection, and its suction pipe (5) is fixing by arc spring leaf (31); Its suction pipe (5) connects by coupling arrangement (22).
Its coupling arrangement (22) is a fixed muffle, its upper and lower rubber cushion (21), (23) passed through link to each other with catheter (2), suction pipe folder (3) respectively, its catheter (2) is a vertebra shape annulus combination with rubber cushion (21) contact jaw, and rubber cushion (21), (23) establish mesopore and suction pipe (5) is combined closely.
The pipettor that the inventor produces is two types, and its suction pipe is movable and fixed two kinds, and it is movable plugged suction pipe for the time spent, need not then pull down and put well, and it is fixed to be fixedly connected for suction pipe and catheter.
Its suction pipe and catheter are provided with metering scale and can accurately show with the body of transparent organic glass and resin material metering display screen and move the liquid metering.
Its operating position:
If with movable: suction pipe is inserted the suction pipe folder connect with coupling arrangement, promptly available one hand is pressed plunger, finishes the liquid work that moves under the retracing spring effect very soon.
If with fixed: then the liquid that only need move connects suction pipe, only need press plunger gently and get final product.
Facts have proved: the utility model pipettor is easy to use, can one-handed performance, and can accurately measure thing liquid, and the operator is worked easily, improve the success ratio of work.
