Abstract
The utility model provides a peristaltic pump used for filling sample liquid, which comprises a grip ring, a roller, a rotor and a motor and also comprises a tube replacing wheel; wherein, the profile is provided with the tube replacing wheel of a spiral slot, which is installed at the upper end face of the rotor. The device does not disassemble other structures of the peristaltic pump and can replace a new pump pipe, which is very convenient for operating.
Description
Technical field
The utility model relates to biochemical analyzer, particularly a kind of application of sample liquid peristaltic pump.
Background technique
In biochemical analysis experiment, be to adopt peristaltic pump to draw, add the sample of liquid and reagent.Peristaltic pump is made up of pressure ring, roller, rotor and motor, when stepper motor drives the rotor rotation, is installed in epitrochanterian roller to hocket extruding and discharging of pump line, liquid quantitatively can be moved to the other end by pump line from an end.Because pump line is compressed by roller and pressure ring,, need often to change so wearing and tearing are bigger.Existing peristaltic pump will be changed pump line and comparatively bother, and pressure ring must be shed earlier, just can change pump line, then needs pressure ring to be loaded onto again, and need readjust the impacting force of pressure ring, can effectively and accurately work to guarantee peristaltic pump.
Summary of the invention
The utility model bothers existing technical problem in order to solve existing peristaltic pump replacing pump line, and a kind of application of sample liquid peristaltic pump that can change pump line automatically is provided.
According to above-mentioned purpose, the utility model provides a kind of application of sample liquid peristaltic pump, comprises pressure ring, roller, rotor, motor, also comprises the replace tubes wheel; Spiral fluted replace tubes wheel is wherein arranged on the profile, be installed in the upper end surface of rotor.
The utility model has been owing to taked above technical measures, other structures of not dismounting peristaltic pump, and the pump line that can more renew is automatically operated very easy.

Fig. 2 is the structural representation of former peristaltic pump rotor.
Fig. 3 is the structural representation of former peristaltic pump rotor and roller.
Fig. 4 is the structural representation of the utility model rotor.
Fig. 5 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of application of sample liquid peristaltic pump, comprise pressure ring 1, roller 2, rotor 3, and stepper motor or actuating motor (not drawing among the figure), wherein the rotor of motor is fixedlyed connected with the rotor 3 of peristaltic pump, several (4) rollers 2 are installed on the rotor 3 uniformly, and the gap that is installed between the pressure ring 1 in rotor 3 outsides can settle pump line 5, the two ends of pump line 5 are fixed.When motor when setting rotational speed, its rotor just drives rotor 3 rotations, the roller 2 that protrudes in rotor 3 also pushes pump line 5 and rotates.Form " pillow " shape liquid in one section pump line 5 between two rollers 2, with rotor 3 rotations, " pillow " shape liquid turns to from the suction side and adds end, and the roller 2 of front discharges pump line 5 earlier, makes " pillow " shape liquid produce pulsation.Go round and begin again like this, peristaltic pump just hockets by 2 pairs of pump lines 5 of roller and pushes and release, comes pumping liquid to move to the other end from an end.
As shown in Figure 2, the rotor 3 of I shape is made of upper-end surface 3-1, attachment post 3-2, lower end surface 3-3.
As shown in Figure 3, roller 2 is installed between upper and lower end face 3-1, the 3-2 of rotor 3, and attachment post 3-2 outer space can be rotated around the axle of self.
As shown in Figure 4, be the improved rotor of the utility model, wherein replace tubes wheel 4 substitutes the upper-end surface 3-1 of former rotor 3, and spiral chute 4-1 is arranged on its profile.
As shown in Figure 5, when peristaltic pump as will change pump line 5 time, as long as pump line 5 is enclosed among the spiral chute 4-1 of replace tubes wheel 4, rotor 3 rotations behind the starting electrical machinery, pump line 5 moves and clamp-ons automatically with spiral chute 4-1 in the space between roller 2 and the pressure ring 1, and it is very easy therefore will to change pump line.
Claims (1)
1, a kind of application of sample liquid peristaltic pump comprises pressure ring (1), roller (2), rotor (3), motor, it is characterized in that: also comprise replace tubes wheel (4); The replace tubes wheel (4) of spiral chute (4-1) is wherein arranged on the profile, and the upper-end surface (3-1) that is installed in rotor (3) is located.
