Description

Technical Field

[0003] Currently, the preparation of reagents in the laboratory mainly relies on manual pipetting and mixing operations. Although manual pipetting and mixing can achieve the configuration of experimental reagents, the experimenters are required to perform repeated shaking operations during the mixing process, which will greatly increase the labor intensity of the experimenters. At the same time, there is a risk of secondary contact between the experimenters and the shaking process, resulting in poor safety during the configuration of experimental reagents.

[0007] The utility model is implemented through the following technical scheme: the utility model proposes a liquid reagent preparation device, including a configuration box, six placement slots are opened at equal intervals on the upper end of the configuration box, a configuration bottle with a bottle cap is placed in each of the placement slots, and an automatic shaking mechanism is installed in the configuration box just below the placement slots, wherein the automatic shaking mechanism includes a sliding rod installed in the middle of the bottom end of each placement slot, a fixing plate installed at the top end of the sliding rod, a rubber clamping ring installed on the periphery of the upper end of the fixing plate, a pulley installed at the lower part of one side wall of the sliding rod, a cam in contact with the bottom of the pulley, a linkage shaft passing through the cam, and a servo motor installed outside the configuration box for driving the linkage shaft to rotate.

[0008] Furthermore, the bottle cap is threadably connected to the configuration bottle, and the configuration bottle is an opaque structure. A rubber stopper for allowing an external syringe to pass through is also fixed in the middle of the bottle cap.

[0012] Furthermore, the inner diameter of the rubber clamp ring matches the outer diameter of the configuration bottle, and the rubber clamp ring is bonded and fixed to the fixing plate.

[0013] By adopting the above technical solution, the rubber clamp ring is mainly used to clamp the configuration bottle to ensure that the configuration bottle shakes up and down together with the fixing plate.

[0014] Furthermore, the pulley is rotatably mounted on the slide rod, and the bottom of the pulley is always in contact with the outer wall of the cam.

[0015] By adopting the above technical solution, the sliding rod can be lifted and lowered reciprocatingly during the contact between the pulley and the outer wall of the cam, thereby achieving the shaking of the liquid in the configuration bottle.

[0016] Furthermore, the linkage shaft passes through the cam and is welded to the cam, and the cam corresponds to the pulley one by one.

[0017] By adopting the above technical solution, the linkage shaft can ensure that the cams rotate synchronously, thereby achieving synchronous shaking and configuration of the reagents in the configuration bottles.

[0018] Furthermore, the servo motor is key-connected to the linkage shaft, and the linkage shaft is rotationally connected to the configuration box.

[0019] By adopting the above technical solution, the servo motor is mainly used to provide power for the rotation of the linkage shaft.

[0020] Furthermore, an operation panel for controlling the convenient opening and closing of the automatic shaking mechanism is installed in the middle of one side wall outside the configuration box.

[0021] By adopting the above technical solution, the operation panel mainly controls the on-demand operation of the automatic shaking mechanism by controlling the on-off of the circuit.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] In order to solve the problem that the preparation of reagents in the laboratory currently mainly relies on manual pipetting and mixing operations, although manual pipetting and mixing can realize the preparation of experimental reagents, since the experimenter needs to perform repeated shaking operations during the mixing process, this will greatly increase the labor intensity of the experimenter. At the same time, since there is a risk of secondary contact between the experimenter and the shaking bottle during the manual shaking process, the safety of the experimental reagents during preparation is poor. When the utility model is used, after the prepared liquid is added to the closed preparation bottle, the servo motor in the automatic shaking mechanism is used to rotate the linkage shaft and the cam, so that the pulley and the slide bar are repeatedly moved up and down during the rotation of the cam, so as to realize the repeated up and down shaking and mixing of the preparation bottle together with the top plate. Since in this shaking mode, after the prepared liquid is added to the preparation bottle, the entire shaking process is automatically carried out, which not only effectively reduces the labor intensity of the experimenter when preparing the experimental reagents, but also avoids the risk of secondary contact between the experimenter and the reagents in the preparation bottle during the shaking process, making the preparation process of the experimental reagents safer.

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] like Figure 1-Figure 3As shown, a liquid reagent preparation device in this embodiment includes a configuration box 2, six placement slots 1 are evenly spaced at the upper end of the configuration box 2, and a configuration bottle 6 with a bottle cap 5 is placed in each placement slot 1. An automatic shaking mechanism 7 is installed in the configuration box 2 just below the placement slot 1, wherein the automatic shaking mechanism 7 includes a slide bar 706 installed in the middle of the bottom end of each placement slot 1, a fixing plate 707 installed at the top of the slide bar 706, a rubber clamp 702 installed on the outer periphery of the upper end of the fixing plate 707, and a rubber clamp 702 installed on the slide bar 706. The pulley 705 at the lower part of one side wall 706, the cam 704 in contact with the bottom of the pulley 705, the linkage shaft 703 passing through the cam 704, and the servo motor 701 installed outside the configuration box 2 for driving the linkage shaft 703 to rotate, the rubber clamping ring 702 is mainly used to clamp the configuration bottle 6 to ensure that the configuration bottle 6 swings up and down with the fixed plate 707. In the process of the pulley 705 contacting the outer wall of the cam 704, the slide rod 706 can be lifted and lowered reciprocatingly, thereby achieving the shaking of the liquid in the configuration bottle 6.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, the bottle cap 5 is threadedly connected to the configuration bottle 6, and the configuration bottle 6 is an opaque structure. At the same time, a rubber stopper 4 for allowing an external syringe to pass through is fixed in the middle of the bottle cap 5. The configuration bottle 6 is the main place for realizing liquid reaction configuration. With the help of a rubber clamp 702, the bottle cap 5 can be automatically closed after the configuration liquid is injected.

[0033] like Figure 1-Figure 3 As shown, in this embodiment, the slide bar 706 passes through the bottom of the placement groove 1 and slides with the bottom of the placement groove 1, so that the slide bar 706 can slide up and down conveniently relative to the placement groove 1. The inner diameter of the rubber clamp 702 matches the outer diameter of the configuration bottle 6. The rubber clamp 702 is bonded and fixed to the fixing plate 707. The pulley 705 is rotatably installed with the slide bar 706, and the bottom of the pulley 705 is always in contact with the outer wall of the cam 704.

[0034] like Figure 1-Figure 3 As shown, in this embodiment, the linkage shaft 703 passes through the cam 704 and is welded to the cam 704. The cam 704 corresponds to the pulley 705 one by one. The linkage shaft 703 can ensure that the cams 704 rotate synchronously, thereby realizing the synchronous shaking configuration of the reagents in each configuration bottle 6. The servo motor 701 is key-connected to the linkage shaft 703, and the linkage shaft 703 is rotatably connected to the configuration box 2. The servo motor 701 is mainly used to provide power for the rotation of the linkage shaft 703. An operation panel 3 for controlling the convenient opening and closing of the automatic shaking mechanism 7 is installed in the middle of the outer side wall of the configuration box 2. The operation panel 3 mainly controls the on-demand operation of the automatic shaking mechanism 7 by controlling the on-off of the control circuit.

[0035] The specific implementation process of this embodiment is as follows: during configuration, the device is first moved to the use position, and the device is connected to an external power supply, and then the configuration bottle 6 is placed in the corresponding placement slot 1, and the liquid to be mixed is added to each configuration bottle 6 through the rubber stopper 4 with the help of an external syringe, and then the linkage shaft 703 is rotated under the action of the servo motor 701. After the linkage shaft 703 rotates, it will drive the cam 704 to rotate, so that during the rotation of the cam 704, the pulley 705 and the slide bar 706 can be repeatedly moved up and down, so as to achieve the configuration bottle 6 to be shaken up and down along with the top plate. Because in this shaking method, when the prepared liquid is added to the configuration bottle 6, the entire shaking process is automatically carried out, which not only effectively reduces the labor intensity of the experimenter when preparing the experimental reagent, but also avoids the risk of secondary contact between the experimenter and the reagent in the configuration bottle 6 during the shaking process, making the configuration process of the experimental reagent safer.
