[0002] A horizontal shaker, also known as a horizontal rotary shaker, is primarily driven by a motor to rotate the shaker base horizontally. This rotational motion allows for uniform mixing and decolorization of laboratory samples within the shaker's container, resulting in widespread applications in biology, medicine, and chemical engineering. Flasks, common laboratory vessels, feature a spherical body and a narrow cylindrical neck. They can be used for holding and heating reagents. Their structure effectively prevents spillage and controls volatilization of reagents.

[0027] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] A kind of horizontal shaking table's fixing device, as shown in Figure 1 、 2 It includes: installation component, guide pillar 1 and limiting component, in the embodiment, installation component is used to fix the flask needing to be shaken, simultaneously installation component is also the moving part of horizontal shaking table, installation component is arranged on the drive base 10 of horizontal shaking table, drive base 10 can move installation component in horizontal direction, and reagent in flask fixed on installation component is shaken evenly. It needs to be explained that, in existing horizontal shaking table, installation component on drive base 10 is replaced according to the container to be fixed, and the connection mode between drive base 10 and installation component is the common connection mode familiar to those skilled in the art, therefore not described in this application.

[0029] A guide column 1 is arranged on the top of the mounting assembly, and the bottom end of the guide column 1 is connected with the top of the mounting assembly. A limiting assembly is arranged on the guide column 1 and can move up and down along the guide column 1. The limiting assembly comprises a center disc 5 and a plurality of locking members 2. The center disc 5 is sleeved on the guide column 1 and can slide up and down along the guide column 1. The center disc 5 can be sleeved on the guide column 1 at the axial center, so that the axial center of the center disc 5 is always on the axis of the guide column 1 during the sliding up and down. Since the outer diameter of the bottle body of the flask is large and the outer diameter of the neck is small, a plurality of accommodating grooves 6 are arranged on the side wall of the center disc 5, and the plurality of accommodating grooves 6 are arranged in a ring shape on the side of the guide column 1. Each of the accommodating grooves 6 can accommodate the neck of a flask. The flask can be moved in a vertical posture to the direction of the guide column 1 to place the neck of the flask in the accommodating groove 6, and the bottle body of the flask has a space for placement. At this time, the part of the bottle body of the flask close to the guide column 1 is located between the center disc 5 and the mounting assembly.

[0030] A locking member 2 is arranged on the side wall of the center disc 5, and the plurality of locking members 2 and the plurality of accommodating grooves 6 are arranged in one-to-one correspondence. The structure of the locking member is shown in Figure 3 Each of the accommodating grooves 6 is provided with a locking member 2 opposite thereto. Each of the locking members 2 is provided with a limiting groove 3 on the side wall of the accommodating groove 6. The opening of the limiting groove 3 is arranged opposite to the opening of the accommodating groove 6. One side of the limiting groove 3 is rotationally connected with the side wall of the center disc 5. When the locking member 2 is closed on the side wall of the center disc 5, the limiting groove 3 and the accommodating groove 6 form a locking gap 14 for accommodating the neck of the flask. The neck of the flask can be clamped and fixed by the limiting groove 3 and the accommodating groove 6. The ring-shaped accommodating grooves 6 and the limiting grooves 3 are matched one by one, and the necks of a plurality of flasks can be fixed in a ring shape on the side of the guide column 1. For example, a rotating shaft 15 is arranged on one side of the limiting groove 3. The locking member 2 is connected with the side wall of the center disc 5 through the rotating shaft 15. The locking member 2 can be opened and closed on the accommodating groove 6 by rotating around the rotating shaft 15, so that the locking gap 14 formed by the accommodating groove 6 and the limiting groove 3 is opened or closed. This facilitates the flask neck to be placed or taken out. After the locking gap 14 is closed, the flask neck can be fixed. In order to keep the locking member 2 in a fixed state of the flask neck, an insertion buckle 11 is arranged on the other side of the limiting groove 3. An insertion hole is arranged on the side wall of the center disc 5 for accommodating the end of the insertion buckle 11. When the locking member 2 is closed on the accommodating groove 6, the end of the insertion buckle 11 can be inserted into the insertion hole. The locking member 2 is locked so that it cannot be opened. The closing state of the locking gap 14 is maintained. The flask neck is stably fixed, and the flask neck is prevented from being taken out of the locking gap 14.

After the neck of the flask is placed in the locking gap 14, the center disc 5 is operated to be lowered on the guide column 1, so that the limiting arc surface and the accommodating arc surface can be pressed on and attached to the outer surface of the flask body. The accommodating arc surface and the limiting arc surface have a large contact area with the flask body, so that the pressure on the flask body can be dispersed, and the flask body can be stably fixed through the shape of the attached arc surface.

[0032] Since the center of gravity of the flask is close to the bottom of the flask after the reagent is filled, in order to fix the flask near the center of gravity, a plurality of fixing grooves 7 for accommodating the bottom of the flask are arranged on the top surface of the mounting seat, and the fixing grooves 7 are opposite to the locking gap 14. In use, the bottom of the flask can be placed in the fixing groove 7, and the limiting assembly is pressed on the flask body. At this time, the accommodating arc surface, the limiting arc surface and the fixing groove 7 cooperate together, the accommodating arc surface and the limiting arc surface press the flask body from the top of the flask body into the fixing groove 7, and the fixing groove 7 can limit the flask bottom in the horizontal direction, so that the flask body close to the center of gravity can be fixed, so that better fixing effect can be obtained, and the shaking caused by the fixing position being too far from the center of gravity of the flask is avoided, and the breakage of the flask made of glass caused by uneven stress is avoided.

It should be noted that the working mode of the horizontal shaking table is to move in the horizontal direction, so the rotating disc needs to be locked to prevent the rotation of the rotating disc from affecting the mixing effect during the working of the horizontal shaking table. Common locking devices such as pins and dampers can be used, so they will not be described in detail in this application.

[0034] Optionally, in order to make the center disc 5 can stably on the guide post 1 up and down movement, the center disc 5 is provided with a guide sleeve 4, the axis of the guide sleeve 4 coincides with the axis of the center disc 5, the center disc 5 is connected with the guide post 1 through the guide sleeve 4.

A plurality of pin holes are arranged in the guide groove 13 for accommodating the positioning pin 12. The plurality of pin holes are uniformly arranged along the length direction of the guide groove 13. The height position of the guide sleeve 4 is locked by inserting the end of the positioning pin 12 into the pin hole, and then the height position of the center disc 5 is locked. The containing curved surface on the center disc 5 and the limiting curved surface on the locking piece 2 can be kept in contact and press the flask body, so that the flask is stably fixed.

[0036] In order to adapt to the cylindrical shape of the flask neck, the containing groove 6 is an arc-shaped groove with an opening facing the outside of the center disc 5, and the limiting groove 3 is an arc-shaped groove with an opening facing the containing groove 6.
