Specific embodiment
Below by specific embodiment and cooperate attached drawing, the utility model is described further.
The present embodiment provides a kind of clamp devices of micro-fluidic chip, as shown in Fig. 2A, Fig. 2 B, Fig. 3 A, Fig. 3 B, cooperate from
Heart equipment uses, for the locking of micro-fluidic chip, especially suitable for round micro-fluidic chip.
Clamp device structure is specifically as shown in Figure 2 B.Clamp device 100 includes rotary-tray 110, fastening grooves 120, determines
Position groove 130, resilient plunger 121, location hole 140, fastener hole 150, fastening grooves 120 and positioning groove 130 are coaxial, and position
130 diameter of groove is greater than fastening grooves 120.The quantity of resilient plunger 121 can be 3-10, and quantity can be according to actual needs
It is chosen, this example is 6.
Wherein, rotary-tray 110, will be micro-fluidic when placing micro-fluidic chip 200 for placing micro-fluidic chip 200
The matched positioning groove 130 of the locating piece 210 of chip 200 is aligned, and is pulled down, and micro-fluidic chip 200 and fastening are prevented
Occur between groove 120 circumferential mobile.In practical applications, the shape of positioning groove 130 matches with locating piece 210, positioning
Block 210 may be stuck in positioning groove 130, and limitation micro-fluidic chip 200 moves in the face XY.In order to guarantee that fastening force is uniform,
