In the prior art, people usually soak and scrub each experimental container with detergent, then rinse it with water continuously for several times, and then place each experimental container on a rack to dry or place it in a heating instrument to dry. The existing cleaning and drying devices need to fix and clamp the experimental containers when in use. Since the shapes of various experimental containers are different, the existing cleaning and drying devices need to set special clamps for experimental containers of different shapes.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0027] The present application embodiment provides an experimental container cleaning device, such as Figure 1 As shown, it includes a base 1, a top plate 5, a rotating platform 4, a clamping mechanism 2, and a telescopic device 3. The rotating platform 4 is rotatably arranged above the base 1, and a plurality of placement grooves 41 are arranged in a circular array on the outside of the rotating platform 4; the clamping mechanism 2 is arranged corresponding to the placement grooves 41 below the rotating platform 4; Figure 2As shown, the clamping mechanism 2 includes an annular structure clamping seat 24, the inner ring of which is provided with a plurality of clamping blocks 21 in a circumferential array, the side of the clamping block 21 facing the center of the clamping seat 24 is a front end face for clamping the experimental container, the inner wall of the clamping seat 24 is penetrated with a telescopic rod 23 arranged to move along the normal direction, the rear end face of the clamping block 21 is hinged to the end of the telescopic rod 23, and the axis direction of the hinge is perpendicular to the axis direction of the clamping seat 24; a reset spring 22 is provided between the clamping block 21 and the telescopic rod 23 or the clamping seat 24, and when the reset spring 22 is in a natural state, the front end face of the clamping block 21 is parallel to the axis of the clamping seat 24; as shown in FIG. Figure 1 As shown, the top surface of the base 1 is provided with a cleaning pipe 12 and a drying pipe 11 in sequence along the rotation direction of the rotating table 4. When the rotating table 4 rotates to a predetermined angle, there is a clamping seat 24 above the cleaning pipe 12 and the drying pipe 11. The base 1 and the top plate 5 are fixedly connected by a fixing plate 51, and a telescopic device 3 is provided below the top plate 5 at the position corresponding to the cleaning pipe 12 and the drying pipe 11, which is used to drive the clamping mechanism 2 to move up and down in a direction perpendicular to the base 1.

[0028] Specifically, several experimental containers are placed in the clamping mechanism 2 through the placement slots 41, and the experimental containers are clamped under the action of the clamping block 21, the reset spring 22, and the telescopic rod 23, with the opening of the experimental container facing downward during clamping; the front end face of the clamping block 21 is in close contact with the outer wall of the experimental container, and the clamping block 21 is adapted to the taper of the side wall of the experimental container through the hinged structure between the clamping block 21 and the telescopic rod 23, so that the clamping mechanism 2 can adapt to clamping experimental containers with different tapers. And after taking out the experimental container, the reset spring 22 is used to restore the clamping block 21 to its original position again, that is, the front end face of the clamping block 21 is parallel to the axis of the clamping seat 24. After that, the rotating table 4 rotates and drives the clamping mechanism 2. When the clamping mechanism 2 holding the experimental container rotates to the top of the cleaning pipe 12, it stops rotating. Under the action of the telescopic device 3, the clamping mechanism 2 is driven to move downward in the direction perpendicular to the base 1, so that the cleaning pipe 12 enters the interior of the experimental container to clean the interior of the experimental container. Because the opening of the experimental container faces downward, the liquid can be automatically discharged during cleaning and impurities are taken away. There is no need to dump the container again, which increases the cleaning strength and saves cleaning time. After the cleaning is completed, under the action of the telescopic device 3, the clamping mechanism is driven 2 moves upward to separate the clamping device 2 from the cleaning pipe 12; under the action of the rotating table 4, the clamping mechanism 2 rotates to the top of the drying pipe 11, and under the action of the telescopic device 3, the clamping mechanism 2 is driven to move downward in the direction perpendicular to the base 1, so that the drying pipe 11 enters the interior of the experimental container to dry the experimental container; after drying, the clamping mechanism 2 is separated from the drying pipe 11 under the action of the telescopic device 3 and continues to rotate, and this reciprocating process can be used to clean and dry the experimental container in each clamping mechanism 2 in turn, which can effectively improve the cleaning efficiency of the experimental container.

[0029] Specifically, in order to improve the stability during the clamping process and prevent the experimental container from falling out of the clamping mechanism 2, a movable rod 25 is swingably provided at the lower part of the clamping block 21, and its swing axis is parallel to the corresponding hinge axis between the clamping block 21 and the telescopic rod 23. An elastic member is provided between the clamping block 21 and the movable rod 25, and a stopper 26 is provided at the end of the movable rod 25; when the elastic member is in a natural state, the end of the movable rod 25 is vertical and faces the axis of the clamping seat 24, and the stopper 26 faces the upper part of the clamping seat 24. The clamping block 21 and the movable rod 25 can be hinged to one end of the movable rod 25 by the lower part of the clamping block 21, and a torsion spring 27 is provided at the hinge axis to realize the function of elastically swinging the movable rod 25 around its hinge axis; Figure 2 As shown, in this embodiment, a groove is provided at the lower part of the clamping block 21, and a torsion spring 27 is arranged in the groove. One end of the torsion spring 27 is connected to the inner wall of the groove, and the other end is connected to the movable rod 25 to realize the elastic swing function. When the experimental container is placed in the clamping mechanism 2, the clamping block 21 gradually clamps the outer wall of the experimental container, and at the same time, the opening of the experimental container pushes the movable rod 25 to swing downward around its swing axis. When the outer wall of the experimental container is clamped by the clamping block 21, the opening edge of the experimental container is just located at the angle formed by the movable rod 25 and the stopper 26, so that the experimental container is fixed in the clamping mechanism 2 and will not fall out of the clamping mechanism 2, thereby improving the stability during the clamping process; after the experimental container is removed, the torsion spring 27 returns to its natural state, and the movable rod 25 returns to the position where its end is vertical and facing the axis of the clamping seat 24.

[0030] Specifically, in order to improve the stability of the mounting structure of the clamping block 21 and prevent the clamping block 21 from swinging relative to the axis of the clamping seat 24, as shown in FIG. Figure 2 As shown, the clamping seat 24 is provided with two telescopic rods 23 corresponding to each clamping block 21 , and the two telescopic rods 23 are located in the same cross section of the clamping seat 24 in the axial direction.

[0031] Specifically, when the clamping block 21 adapts to the taper of different experimental containers, the clamping block 21 will rotate around the hinge axis of the end of the telescopic rod 23. After the experimental container is removed, the clamping block 21 needs to be restored to a state where its front end surface is parallel to the axis of the clamping seat 24 to prepare for clamping the next experimental container. To achieve the above function, Figure 2 As shown, a pair of return springs 22 are provided between the clamping block 21 and the clamping seat 24 . The two return springs 22 are along the axial direction of the clamping seat 24 , and the two return springs 22 are respectively located above and below the telescopic rod 23 .

[0032] Specifically, Figure 2As shown, the front end surface of the clamping block 21 is provided with a V-shaped groove along the axial direction of the clamping seat 24, and the angle between the two inner walls of the V-shaped groove is an obtuse angle. The two inner walls of the V-shaped groove are used to clamp the experimental container. The provision of the V-shaped groove can increase the contact area between the clamping block 21 and the experimental container, improve the clamping stability, and better adapt to experimental containers of different outer diameters.

[0033] Specifically, Figure 1 and Figure 3 As shown, guide rods 32 are vertically penetrated on both sides of the corresponding placement groove 41 of the rotating table 4, the upper ends of the guide rods 32 on both sides of the same placement groove 41 are connected by a movable plate 33, the lower ends of the guide rods 32 on both sides of the same placement groove 41 are connected to the clamping seat 24, the movable plate 33 is connected to the movable end of the telescopic device 3, and the telescopic device 3 drives the clamping mechanism 2 to move up and down in a direction perpendicular to the base 1 through the movable plate 33 and the guide rods 32.

[0034] More specifically, Figure 1 and Figure 3 As shown, a vertical spring 31 is sleeved on the guide rod 32 between the movable plate 33 and the rotating table 4. When the vertical spring 31 is in a natural state, the clamping mechanism 2 is away from the base 1. After the experimental container in the clamping mechanism 2 is cleaned or dried, the vertical spring 31 returns to the natural state, driving the movable plate 33 to move upward, thereby driving the clamping mechanism 2 away from the base 1, so that the experimental container is separated from the cleaning tube 12 or the drying tube 11.

[0035] More specifically, Figure 1 and Figure 3 As shown, a conical hole 34 is provided on the top of the movable plate 33, and a conical rod 35 is provided at the lower end of the movable end of the telescopic device 3, with its small end facing downward, for matching the conical hole 34. The conical rod 35 cooperates with the conical hole 34, which not only positions the movable plate 33 and the clamping mechanism 2 to improve the relative position accuracy of the experimental container and the cleaning tube 12 and the drying tube 11, but also pushes the guide rod 32 to move downward, and facilitates separation. In this embodiment, the telescopic device 3 is a linear cylinder.

[0036] Specifically, Figure 1 As shown, a column 14 is coaxially connected to the lower part of the rotating table 4, and the lower end of the column 14 is rotatably arranged on the base 1. A driving motor can be arranged at the bottom of the base 1 to drive the column 14 to rotate, thereby driving the rotating table 4 to rotate.

[0037] Specifically, Figure 1 As shown, drain grooves 13 are provided downwardly around the cleaning pipe 12, and guide holes are provided at the bottom of the drain grooves 13 to achieve rapid drainage and improve cleaning efficiency.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
