[0001] The present application belongs to the field of biological experiment technology, and in particular relates to a beaker clamping and transferring device. Background Art

[0002] During biological experiments, when the reagents need to be added, beakers are usually used as carriers of the reagents. The beakers are then placed in a heating furnace one by one and evenly distributed in the furnace. After heating, the beakers are taken out of the furnace one by one. The general heating furnace is a box structure with an opening at the top and a rotating cover. In order to avoid contamination of the reagents in the beaker, the experimenter usually uses a special clamp to put in and take out the beaker.

DETAILED DESCRIPTION

[0023] 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.

[0024] The present application embodiment provides a beaker clamping and transferring device, such as Figure 1 and Figure 2 As shown, including:

[0025] The mounting frame 1 comprises two rectangular frames 11, one of which is located inside the other, the two ends of the two rectangular frames 11 are abutted against each other and are cross-arranged, the projections of the two ends of the two rectangular frames 11 along the length direction are in an "X" shape, the middle parts of the two ends of the two rectangular frames 11 are hingedly connected, and one side of the two rectangular frames 11 is used for handholding; the clamping mechanism 2, the clamping mechanism 2 in this embodiment is set to three, and the number of the clamping mechanism 2 can also be reasonably set according to needs, the clamping mechanism 2 is installed on the other side of the two rectangular frames 11, and is used to clamp the beaker, and the adjacent clamping mechanisms 2 are separated by the same predetermined distance, and the predetermined distance is adjustable. When in use, before putting the beaker into or taking it out of the heating furnace, the operator can adjust the predetermined distance between the clamping mechanisms 2 according to the distance between the beakers; after the predetermined distance between the clamping mechanisms 2 is adjusted, the operator holds one side of the rectangular frame 11 to separate the one side of the two rectangular frames 11 from each other. Since the two rectangular frames 11 are hingedly connected at the middle of both ends, the other side of the two rectangular frames 11 will also be separated from each other. At this time, the clamping mechanism 2 installed on the other side of the two rectangular frames 11 is in an open state, and the clamping mechanism 2 is placed on the beaker; then the one side of the two rectangular frames 11 is brought close to each other, and the clamping mechanism 2 enters a clamping state. The operator needs to press against one side of the two rectangular frames 11 to prevent the one side of the two rectangular frames 11 from separating, thereby clamping the beaker, and then putting the clamped beaker into or taking it out of the heating furnace. Through the hinged arrangement of the two rectangular frames 11 and the arrangement of three clamping mechanisms 2 with adjustable spacing, the device can not only clamp and transfer beakers in batches, but also be adapted to clamp beakers with a predetermined spacing, thereby improving the applicability of the device and thus improving the experimental efficiency.

[0026] Specifically, Figures 1 to 3As shown, the middle parts of both ends of the two rectangular frames 11 are hingedly connected by the mounting shaft 12; the clamping mechanism 2 includes a pair of rotating plates 22, one end of the rotating plates 22 is slidably arranged on the mounting shaft 12 and is rotatably connected to the mounting shaft 12, and the other end is connected to a mounting plate 23, the other side of the rectangular frame 11 is a fixed shaft 13, the side surfaces of the two rotating plates 22 are provided with matching holes 221 along the length direction of the mounting shaft 12, and the two rotating plates 22 are respectively slidably penetrated on the fixed shafts 13 of different rectangular frames 11 through the matching holes 221; the two mounting plates 23 are arranged opposite to each other, and the mounting plates 23 and the corresponding rotating plates 22 are at a predetermined angle; a spring sheet 24 is rotatably arranged at one end of the two mounting plates 23 facing each other, the rotation axis of the spring sheet 24 is parallel to the mounting shaft 12, and the spring sheet 24 is in an arc shape. When one side of the two rectangular frames 11 is close to each other, the spring sheet 24 is used to contact the cup wall of the beaker, and the inner arc surface of the spring sheet 24 is provided with an anti-slip portion 241. When in use, when one side of the two rectangular frames 11 is brought together or separated, the rotating plate 22 is driven by the fixed shaft 13 to rotate one end of the rotating plate 22 around the mounting shaft 12. When one side of the two rectangular frames 11 is brought together, the two spring sheets 24 are driven to move together. The spring sheets 24 can adapt to beakers of different cup diameters. As the one side of the two rectangular frames 11 moves together, the spring sheets 24 gradually approach the beaker wall, and under the contact with the beaker wall, the spring sheets 24 start to rotate and automatically fit the wall, and the anti-slip part 241 acts to stably clamp the beaker. The structural design of the fixed shaft 13, the rotating plate 22 and the spring sheets 24 not only optimizes the structure of the device, but also improves the clamping effect of the clamping mechanism 2.

[0027] Specifically, Figure 1 As shown, the distance between the two spring sheets 24 on the clamping mechanism 2 and the mounting shaft 12 is always equal, ensuring that when one side of the two rectangular frames 11 is brought close together, the two spring sheets 24 can contact the beaker wall at the same time, so that both sides of the beaker are evenly stressed, thereby making the beaker clamped more stably and further improving the clamping effect of the clamping mechanism 2.

[0028] Specifically, Figures 1 to 3 As shown, the clamping mechanism 2 also includes a matching shaft 21, with annular stoppers 211 formed at both ends thereof, a through hole 212 is opened on the matching shaft 21 along its own axis, the matching shaft 21 is sleeved on the mounting shaft 12 through the through hole 212, and is movably arranged along the mounting shaft 12, and one end of a pair of rotating plates 22 is rotatably matched with the matching shaft 21. In the manner that the matching shaft 21 is sleeved on the mounting shaft 12, the clamping mechanism 2 is movably arranged along the mounting shaft 12.

[0029] Specifically, Figure 1 and Figure 3As shown, the matching hole 221 on the rotating plate 22 is located at a lower middle position of the rotating plate 22 to extend the force arm applied to one side of the two rectangular frames 11, so that when the operator brings the one side of the two rectangular frames 11 closer with a smaller force, the clamping mechanism 2 can obtain a larger clamping force, saving the operator's physical strength and improving the convenience of the device.

[0030] Specifically, Figures 1 to 4 As shown, springs 3 are provided between adjacent clamping mechanisms 2, and the stiffness coefficients of the springs 3 are equal. The two outermost clamping mechanisms 2 are provided with locking mechanisms 4, which include a support plate 41 arranged on the side of one end of the rotating plate 22 and parallel to the mounting shaft 12. The support plate 41 can also be installed on the annular limit platform 211 of the matching shaft 21. A through hole 42 is opened on the support plate 41, and a locking pin 43 is inserted in the through hole 42. A plurality of locking holes 44 for matching with the locking pin 43 are evenly distributed on the mounting shaft 12. When used, before clamping the beaker, the operator needs to adjust the predetermined distance between each clamping mechanism 2 according to the distance between each beaker, and the operation method is as follows: pull or push the support plate 41 installed on the side of one end of the transfer plate 22 of the two outermost clamping mechanisms 2 or the annular limit platform 211 of the matching shaft 21, and under the action of the spring 3, the predetermined distance between each clamping mechanism 2 is increased or decreased while being always equal; after adjusting the distance between the clamping mechanisms 2, select the corresponding locking hole 44 on the installation shaft 12, and insert the locking pin 43 through the through hole 42 on the support plate 41 and into the corresponding locking hole 44 to lock the position of the clamping mechanism 2. Under the action of the spring 3, and through the matching relationship between the locking hole 44 on the installation shaft 12 and the through hole 42 on the support plate 41, the operator can uniformly adjust the distance between each clamping mechanism 2 and lock the position of the clamping mechanism 2 in a simple way, which further simplifies the operation method of the device, improves the applicability of the device, and is conducive to improving the experimental efficiency.

[0031] 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.
