Description

Technical Field

[0001] The utility model relates to the technical field of electric stirrers, in particular to a fixing device for an electric stirrer. Background Art

[0002] An electric stirrer is a device that forces convection and uniform mixing of liquid and gaseous media. The type, size, speed, power and other parameters of the stirrer have an important influence on the effect of medium mixing. Different stirring processes require different stirring devices to operate. When designing and selecting, the type of stirrer, motor power, stirring speed, and then the reducer, frame, stirring shaft, shaft seal and other components must be determined according to the purpose and requirements of the stirring operation.

[0003] Some existing biological laboratories are also equipped with electric stirrers to facilitate mixing of various solutions. However, most of the existing electric stirrers are fixed by a C-shaped frame connected by threads. When in use, the C-shaped frame can only maintain the stability of the entire electric stirrer. When the electric stirrer stirs the solution, it will shake under the action of centrifugal force and the solution, causing the stirring blades to contact the beaker during the stirring process, which not only affects the stirring effect of the solution, but also causes the beaker to break.

[0004] At the same time, when the existing electric stirrer is in use, the beaker will also shake under the action of centrifugal force. When the beaker and the electric stirrer are used together, the staff usually limit the position of the beaker manually, which is not only inconvenient but also affects the applicability of the electric stirrer.

Under the cooperation of the positioning rod 6 and the positioning groove 4, the fixing rod 5 can be limited so that it can always apply pressure to the suction cup 3, effectively improving the fixing effect of the suction cup 3. A connecting groove 7 is provided on one side of the bottom of the inner cavity of the base 1. The connecting groove 7 is a U-shaped structure design. The connecting groove 7 is connected with the installation groove 2. A pushing mechanism 8 is installed in the inner cavity of the connecting groove 7. Under the cooperation of the pushing mechanism 8, when it is necessary to release the adsorption of the suction cup 3 on the desktop, the negative pressure state inside the suction cup 3 can be destroyed, so as to facilitate the movement of the device. Sliding blocks 9 are slidably connected to both sides of the inner cavity of the base 1, and one side of the sliding block 9 is fixed A tension spring 10 is connected, and the other side of the tension spring 10 is fixedly connected to the surface of the sliding block 9 on the other side. The middle part of the tension spring 10 is fixedly connected to the inner wall of the base 1. Under this action, after the sliding block 9 moves, the tension spring 10 can apply a reverse pulling force to the sliding block 9, so as to facilitate subsequent use. The top of the sliding block 9 is fixedly connected to a limiting frame 11. The limiting frame 11 is a U-shaped structure design. The limiting frame 11 is symmetrically designed with the center of the base 1. Under this action, it is convenient to fix the beaker, which effectively improves the stability of the beaker. Balls 12 are installed on both sides of the surface of the limiting frame 11. The ball 12 can facilitate the fixation of the beaker. Under this action, the beaker is placed on the two limiting frames. 11, with the cooperation of the tension spring 10 and the sliding block 9, the beaker can be fixed so that it will not easily shift in position. The inner cavity of the base 1 is fixedly connected with a guide rod 15, and the other end of the guide rod 15 passes through the other side of the sliding block 9 and is slidably connected to the inner wall of the penetration point. Under this action, the sliding block 9 can be guided when it moves, so that it can be more stable when moving, avoiding the sliding block 9 from being unstable when moving and having a large position shift, which affects the fixing effect of the ball 12 on the beaker. The guide rod 15 is located inside the tension spring 10. Under this action, the tension spring 10 can be guided when it is stretched or rebounded, so that it can be more stable when moving.

[0023] The pushing mechanism 8 includes a movable frame 81, the surface of the movable frame 81 is slidably connected to the inner wall of the connecting groove 7, and two places on one side of the movable frame 81 are fixedly connected with pushing rods 82. One side of the pushing rod 82 is designed as a semi-conical structure. The bottom of the pushing rod 82 is on the same horizontal line as the bottom of the base 1. One end of the pushing rod 82 is used in conjunction with the surface of the suction cup 3. With the cooperation of the shape of the pushing rod 82, the suction cup 3 can be squeezed by the pushing rod 82, thereby relieving the negative pressure state inside the suction cup 3, which is convenient for moving the device. One side of the movable frame 81 is fixedly connected with a connecting rod 83, and the other end of the connecting rod 83 penetrates to the outside of the base 1 and is slidably connected to the inner wall of the penetration point. The surface of 83 is fixedly connected with a compression spring 84, and the other end of the compression spring 84 is fixedly connected to the surface of the base 1. Under this action, when it is necessary to release the negative pressure of the suction cup 3, the connecting rod 83 can be pushed to make it contact with the suction cup 3 through the cooperation of the movable frame 81, thereby releasing the negative pressure state of the suction cup 3, which is more convenient. The two sides of the inner cavity of the connecting groove 7 are fixedly connected with a locking rod 14, and the other end of the locking rod 14 passes through the other side of the movable frame 81 and is slidably connected to the inner wall of the penetration point. Under this action, the movable frame 81 can be limited so that it will not be easily moved out from the inside of the connecting groove 7, effectively improving the stability of the movable frame 81 during movement.

[0024] Working principle: first, install the electric stirrer on the device through the fixing groove 13, then move the device to a suitable position, then press the fixing rod 5 to make the positioning rod 6 enter the interior of the positioning groove 4, and at the same time, the fixing rod 5 can squeeze the suction cup 3, so that the base 1 is fixed with the cooperation of the suction cup 3, then rotate the fixing rod 5 to drive the positioning rod 6 to rotate to the other side of the inner cavity of the positioning groove 4, so that the positioning rod 6 will not move easily, effectively improving the squeezing effect on the suction cup 3, and then place the solution to be stirred on the top of the base 1 through the beaker, and with the cooperation of the tension spring 10, the sliding block 9 can be driven to move, so that the limit frame 11 can drive the ball 12 to contact the beaker, thereby fixing the beaker, and then turn on the electric stirrer for stirring, and take out the beaker after stirring. When the device needs to be moved, the staff makes the positioning rod 6 correspond to the opening on one side of the positioning groove 4, and then pushes the connecting rod 83 to drive the push rod 82 through the movable frame 81 to cooperate with the negative pressure inside the suction cup 3.
