Description

Technical Field

[0001] This utility model relates to the field of batch fixing technology for graduated straws, and more specifically, to a fixing device for drying graduated straws. Background Technology

[0002] Graduated pipettes, as core laboratory tools, are used for the precise transfer of trace amounts of liquids in chemical analysis and biological experiments, such as preparing standard solutions and dispensing cell culture media. After use, graduated pipettes need to be cleaned and dried before reuse. To facilitate batch draining and batch feeding into a dryer, multiple graduated pipettes are usually pre-inserted into a fixing device, which is then lifted into an oven for batch drying. For example, patent CN103512328A discloses a pipette drying bracket in which multiple graduated pipettes are fixed by inserting them into holes in a cylindrical shell. However, although this can fix multiple graduated pipettes, the various sizes of the pipettes (i.e., differences in thickness and length) make it easy for the graduated pipettes to fall off during transfer due to the cylindrical shell as the fixing device.

[0003] Based on the above description, there is an urgent need for a drying device suitable for straws with multiple sizes of graduations. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for drying graduated straws, which aims to solve the technical problem that existing fixing devices for drying graduated straws cannot stably insert graduated straws of multiple sizes.

Detailed Implementation

[0018] The specific implementation method is described below with reference to the accompanying drawings.

[0019] Example 1 Please see Figures 1 to 4 The present invention provides the following technical solution: a fixing device for drying graduated straws, which is suitable for fixing graduated straws of multiple sizes so as to send them into the drying oven for drying.

[0020] Specifically, such as Figure 1 and Figure 4 As shown, a fixing device for drying graduated straws includes a first upright plate 1, a second upright plate 2, a connecting horizontal plate 3, and a multi-row limiting component 4; the first upright plate 1 and the second upright plate 2 are disposed opposite each other at both ends of the connecting horizontal plate 3; the multi-row limiting component 4 is disposed at intervals between the first upright plate 1 and the second upright plate 2; the two ends of the limiting component 4 are respectively connected to the first upright plate 1 and the second upright plate 2.

[0021] In this embodiment, the first upright plate 1 and the second upright plate 2 are connected by a connecting horizontal plate 3, and the three together form a basic frame. Furthermore, the multi-row limiting components 4 are used to radially limit the graduated straws of different sizes. Combined with the connecting horizontal plate 3 located at the bottom of the first upright plate 1, the axial limiting of the graduated straws can be achieved. The two ends of the multi-row limiting components 4 are respectively connected to the first upright plate 1 and the second upright plate 2. Thus, it can not only fix the limiting components 4, but also reinforce the basic frame and improve its stability. Therefore, after batch limiting and fixing of multi-size graduated straws, the stability during the transfer to the oven can be guaranteed.

[0022] In this embodiment, each column of limiting components 4 can be set to different heights to accommodate straws of different lengths; in addition, for easy transfer, both the first upright plate 1 and the second upright plate 2 are provided with operating ear plates to facilitate the lifting and transfer by the staff with both hands.

[0023] Specifically, such as Figures 1 to 4As shown, the multi-row limiting components 4 each include multiple limiting perforated plates 41; the multiple limiting perforated plates 41 are arranged in layers along the vertical direction; each layer of limiting perforated plates 41 has multiple sets of perforation arrays; the corresponding perforations in the perforation arrays of each layer of limiting perforated plates 41 have their central axes coincident in the vertical projection direction. It also includes a third upright plate 5; the third upright plate 5 is perpendicular to the connecting horizontal plate 3; one end of the limiting component 4 away from the first upright plate 1 passes through the third upright plate 5 and extends towards the second upright plate 2. The third upright plate 5 has multiple open slots 51 parallel to the first upright plate 1; each pair of slot sidewalls of the open slots 51 is provided with multiple first locking slots spaced apart; one end of the limiting perforated plate 41 is connected to the first upright plate 1; the other end of the limiting perforated plate 41 passes through the open slots 51 and extends towards the second upright plate 2; the limiting perforated plate 41 is provided with multiple first elastic locking blocks 411 that are embedded in the first locking slots.

[0024] In this embodiment, in order to meet the requirements of batch insertion of graduated straws and ensure the stability of the frame, a third upright plate 5 is further set between the first upright plate 1 and the second upright plate 2 to reinforce the middle section of the limiting hole plate 41. In addition, multiple first elastic blocks 411 are protruding on both sides of the limiting hole plate 41 to be inserted into the first slot, which can not only play a reinforcing role, but also facilitate disassembly and assembly.

[0025] In this embodiment, the same limiting perforated plate 41 can be provided with multiple perforation arrays with different perforation diameters. The perforation arrays of the limiting perforated plates 41 in the same column but different layers correspond to each other to ensure that the graduated pipette can pass through vertically. In addition, in order to improve the drying rate of the graduated pipette, multiple drainage holes can be provided on the connecting horizontal plate. The diameter of the drainage hole is smaller than the constriction end opening of the graduated pipette. In addition, a supporting horizontal plate with the same structure as the limiting perforated plate 41 can be preferred. The supporting horizontal plate is connected to the first vertical plate 1 and the second vertical plate 2 in the same way. The difference is that the diameter of the drainage hole provided on the supporting horizontal plate is smaller than the perforation diameter of the limiting perforated plate 41, but the central axes of the two coincide in the vertical projection direction.

[0026] In this embodiment, the perforation diameters of the multiple perforated arrays are different, that is, the same column of limiting perforated plates 41 can simultaneously fix multiple sizes of graduated straws.

[0027] In this embodiment, the perforation diameters of the multi-row limiting perforated plates 41 are different, that is, the multi-row perforated plates 41 of different rows can also fix graduated straws of different sizes.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, a second elastic block 412 protrudes from one end of the limiting hole plate 41; a plurality of second slots 11 are recessed at the opposite ends of the first vertical plate 1 and the third vertical plate 5 for the second elastic block 412 to be inserted; the plurality of second slots 11 are distributed at intervals along the direction perpendicular to the connecting horizontal plate 3; the open end of the second slot 11 is opposite to the open slot body 51.

[0029] In this embodiment, multiple second slots 11 are distributed at intervals along a direction perpendicular to the connecting horizontal plate 3, thereby facilitating the adjustment of the number of limit hole plates 41 in the same row or the longitudinal interval distance according to different length scale suction tubes.

[0030] In this embodiment, the elastic blocks are made of materials such as fluororubber and polyurethane, which can achieve snap-fit ​​through deformation.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, the second vertical plate 2 is provided with a strip groove 21 at one end near the third vertical plate 5; the strip groove 21 is arranged opposite to the open groove 51; the limiting hole plate 41 is provided with a slider 413 at one end away from the first vertical plate 1; the slider 413 slides into the top opening of the strip groove 21.

[0032] In this embodiment, the end of the limiting hole plate 41 away from the first upright plate 1 can also be connected by a snap-fit ​​method. However, for ease of disassembly, it can be left unconnected. In order to ensure stability, in addition to providing a strip groove 21 for the slider to be embedded to limit the end of the limiting hole plate 41, it is also necessary to ensure that the distance between the third upright plate 5 and the second upright plate 2 is less than 1 / 2 of the length of the connecting horizontal plate 3. Then, the other end of the limiting hole plate 41 is fixed by snap-fitting it with the third upright plate 5. In addition, the limiting hole plate 41 can be lengthened and the number of third upright plates 5 can be increased according to the size of the oven and the number of graduated straws.
