Referring to fig. 1-6, the present embodiment provides a multichannel pipettor 200, where the multichannel pipettor 200 includes a fixing base 210, a guide rod 220, a variable distance member 230, and a plurality of pipettors 240;
the guide rod 220 and the distance-changing piece 230 are both connected with the fixed seat 210, and at least one of the guide rod 220 and the distance-changing piece 230 is movably connected with the fixed seat 210; a plurality of pipettors 240 are slidably connected to the guide 220; the pitch-variable member 230 is provided with a plurality of sliding chutes 231, and each pipette 240 is correspondingly matched with one sliding chute 231; along the extending direction of the sliding slots 231, the interval between any two adjacent sliding slots 231 is gradually increased or gradually decreased;
when there is relative movement between the pipettes 240 and the pitch varying member 230 along the extending direction of the slide slot 231, the pitch varying member 230 is used to drive the pipettes 240 to slide relative to the guide rod 220, so as to adjust the distance between any two adjacent pipettes 240.
Referring to fig. 1-6, the multi-channel pipette 200 works according to the following principle:
the multichannel pipettor 200 includes a holder 210, a guide 220, a pitch piece 230, and a plurality of pipettors 240; the guide rod 220 and the distance-changing piece 230 are both connected with the fixed seat 210, and at least one of the guide rod 220 and the distance-changing piece 230 is movably connected with the fixed seat 210; a plurality of pipettors 240 are slidably connected to the guide 220; the pitch-variable member 230 is provided with a plurality of sliding chutes 231, and each pipette 240 is correspondingly matched with one sliding chute 231;
along the extending direction of the sliding slots 231, the interval between any two adjacent sliding slots 231 is gradually increased or gradually decreased; pitch varying element 230 is configured to drive a plurality of pipettors 240 to slide relative to guide 220, thereby adjusting a distance between any two adjacent pipettors 240.
Therefore, when there is relative movement between the pipettes 240 and the distance varying member 230 along the extending direction of the slide slot 231, each pipettor 240 is correspondingly engaged with one slide slot 231, so as to drive the pipettes 240 to slide relative to the guide rod 220 along with the movement of the pipettes 240 relative to the corresponding slide slot 231, and further adjust the distance between two adjacent pipettes 240 along with the change of the distance between two adjacent slide slots 231, that is, by such an arrangement, the distance between any two adjacent pipettes 240 can be adjusted, so that the multi-channel pipettor 200 can adapt to the interaction requirements of containers with different distances, that is, the application range of the multi-channel pipettor 200 can be expanded; moreover, due to the arrangement mode, the multichannel pipettor 200 can meet the container interaction requirements of various intervals, so that the multichannel pipettor 200 can be used instead of the pipettors 240 with various fixed intervals, and the use cost of the multichannel pipettor 200 can be reduced.
In summary, when the chutes 231 of the pitch-varying member 230 are disposed, the adjustable range of the pitch of the pipetter 240 may be adjusted by adjusting the pitch between two adjacent chutes 231, so that, in the embodiment of the present invention, the maximum pitch between two adjacent chutes 231 may be 16.3mm (see fig. 2 and 6), and the minimum pitch may be 9mm (see fig. 3 and 6).
It should be noted that, as can be seen from the above, at least one of the guide rod 220 and the distance varying member 230 is movably connected to the fixed seat 210, and when adjusting the distance between two adjacent pipettes 240, a manner is adopted in which the pipettes 240 and the distance varying member 230 move relative to each other along the extending direction of the chute 231, so that the pipettes 240 moving along the extending direction of the chute 231 can slide relative to the guide rod 220 along with the change of the distance between the chutes 231, thereby adjusting the distance between two adjacent pipettes 240, and therefore, during this process, when the guide rod 220 is movably connected to the fixed seat 210 and the distance varying member 230 is fixedly connected to the fixed seat 210, the pipettes 240 and the distance varying member 230 can move relative to each other through the movement of the guide rod 220 relative to the fixed seat 210; under the condition that the guide rod 220 is fixedly connected with the fixed seat 210 and the pitch-varying piece 230 is fixedly and movably connected with the fixed seat 210, relative movement between the pipettors 240 and the pitch-varying piece 230 can be realized through the movement of the pitch-varying piece 230 relative to the fixed seat 210; in the embodiment, the distance-changing element 230 is movably connected to the fixing base 210, and the guide rod 220 is connected to the fixing base 210.
It should be further noted that, referring to fig. 1 to fig. 6, in the present embodiment, a multi-channel pipette 200 is taken as an example of a four-channel pipette 240 including four pipettes 240, and correspondingly, four sliding grooves 231 are disposed on the pitch varying member 230, and each sliding groove 231 is correspondingly matched with one pipette 240; in other embodiments of the present invention, the number of pipettes 240 in the multichannel pipettor 200 may be adjusted as needed.
Further, as can be seen from the above, in the embodiment, the guide rod 220 is fixedly connected with the fixing seat 210, and the distance varying piece 230 is movably connected with the fixing seat 210, so that the distance between any two adjacent pipettes 240 is adjusted by driving the pipettes 240 to slide relative to the guide rod 220 through the movement of the distance varying piece 230 relative to the fixing seat 210, in this case, when the distance varying piece 230 is disposed, the distance varying piece 230 and the fixing seat 210 can be rotatably connected; that is, the distance varying member 230 rotates relative to the fixing seat 210 to drive the plurality of pipettors 240 to slide relative to the guide rod 220, so as to adjust the distance between any two adjacent pipettors 240.
In the case that the variable distance member 230 is rotatably connected to the fixing base 210, when the variable distance member 230 and the sliding grooves 231 are provided, the variable distance member 230 may be provided as a cylinder, and the plurality of sliding grooves 231 are provided on the outer circumferential surface of the variable distance member 230 around the axis of the variable distance member 230. Therefore, each pipettor 240 is matched with different positions of the slide groove 231 by rotating the distance varying piece 230 relative to the fixing seat 210, that is, each pipettor 240 and the corresponding slide groove 231 move relatively, so that along with the rotation of the distance varying piece 230, a plurality of pipettors 240 can be driven to slide relative to the guide rod 220, and the purpose of adjusting the distance between any two adjacent pipettors 240 is achieved.
When the pitch varying member 230 is rotatably connected to the fixing base 210, in order to enable the pipettors 240 to smoothly slide relative to the guide rod 220 along with the rotation of the pitch varying member 230, and the movements of the pipettors 240 are synchronized, the axis of the pitch varying member 230 rotating relative to the fixing base 210 is parallel to the sliding direction of the pipettors 240 relative to the guide rod 220.
When the variable pitch part 230 is driven to rotate, the multi-channel pipette 200 further includes a motor 250 and a transmission gear 260, the motor 250 is in transmission connection with the transmission gear 260, the transmission gear 260 is connected with the variable pitch part 230, and the motor 250 is used for driving the variable pitch part 230 to rotate. Therefore, with such an arrangement, the pitch varying piece 230 can be driven to rotate by the motor 250, and the rotating angle of the pitch varying piece 230 is controlled by controlling the motor 250, so that the purpose of adjusting the distance between two adjacent pipettes 240 is achieved.
Based on the above structural arrangement, when the slide slots 231 are arranged, the head end and the tail end of each slide slot 231 can be blocked, so that the arrangement mode can avoid the interference of the sliding of the two adjacent pipettors 240, and the adjustment range of the distance between the two adjacent pipettors 240 by the unidirectional rotation of the pitch-varying member 230 can be expanded.
Different from the above arrangement, in other embodiments of the present invention, the guide rod 220 or the distance-changing member 230 may also be slidably connected to the fixing base 210; in addition, in order to guide the sliding of the guide rod 220 or the distance-changing element 230, the fixing base 210 is provided with a guide groove in sliding fit with the guide rod 220 or the distance-changing element 230. Therefore, when the guide rod 220 or the pitch-varying member 230 is slidably connected to the fixing base 210, the pitch-varying member 230 is a plate, and the sliding grooves 231 are all strip-shaped grooves formed in the pitch-varying member 230.
In order to enable the pipettes 240 to slide smoothly relative to the guide 220 and synchronize the movement of the pipettes 240, the sliding direction of the pitch piece 230 or the guide 220 relative to the fixing base 210 is perpendicular to the sliding direction of the pipettes 240 relative to the guide 220.
Referring to fig. 1 to 6, when the distance between two adjacent pipettes 240 is adjusted by the above embodiments, in order to facilitate a user to read the distance between two adjacent pipettes 240, the multi-channel pipettor 200 further includes an indicator, the indicator is connected to the variable distance member 230, and an indication scale is disposed on an outer circumferential surface of the fixing base 210; the indicator is used to move synchronously with pitch change 230 to indicate the spacing between two adjacent pipettes 240 by an indication scale.
By this arrangement, the simultaneous movement of the indicator and the distance varying member 230 can be used to indicate the fitting position of each pipette 240 relative to the corresponding slide slot 231 at different positions of the distance varying member 230, so that the distance between two adjacent pipettes 240 can be shown according to the fitting position of each pipette 240 and the corresponding slide slot 231.
In the above reading method, when each pipette 240 is engaged with the corresponding slide groove 231 at different positions, the corresponding distance is determined, and the indication scale is created according to the obtained distance values.
Therefore, for example, in the above description, when the distance varying member 230 is rotatably connected to the fixing base 210, when the indication scale is set, each pipette 240 is matched with a different position of the corresponding chute 231 every time the distance varying member 230 rotates by a certain angle along with the rotation of the distance varying member 230, so that the distance between two adjacent chutes 231 is changed, and thus, each rotation angle of the distance varying member 230 corresponds to the distance value between two adjacent pipettes 240, and after the distance value corresponding to each rotation angle is obtained, the distance varying member is arranged on the fixing base 210 around the rotation axis of the distance varying member 230; then, after the indicator is connected to the distance piece 230 so that the distance piece 230 and the indicator move synchronously, and after the distance piece 230 and the indicating scale are calibrated, normal reading can be performed.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
