Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to an inclined test tube culture rack. Background Art

[0002] Inclined test tube culture medium is mainly used for strain expansion and transfer and strain preservation. The sealing effect of the test tube inclined culture medium is better than that of the flat surface. It is not easy for miscellaneous bacteria to enter, and it can be used for the long-term preservation of pure bacteria. The culture area of ​​the inclined culture medium is large, and the number of microorganisms cultured in a test tube can be effectively increased. Chinese patent document CN103769260A discloses a test tube inclined display rack with adjustable inclination, which includes a plate body, a base frame and a bracket. The two ends of the upper surface of the plate body are provided with test tube placement grooves, and the two sides of the two ends of the plate body are provided with holes. The base frame is hinged on the two holes at one end of the plate body, and the bracket is hinged on the two holes at the other end of the plate body. The base frame is provided with a serrated protrusion, and the bracket can slide on the protrusion to change the inclination of the plate body; the display rack realizes the change of the inclination of the plate body by sliding the bracket on the protrusion, thereby changing the inclination of the test tube inclined surface as needed. However, the rack only fixes the test tubes by the friction between the silicone layer on the inner wall of the test tube placement groove and the test tubes. The test tubes have low stability and are prone to shaking or rolling during angle adjustment, which in turn causes leakage of the culture medium in the test tubes, external environment affecting the culture conditions in the test tubes, and failure in making the inclined surface. At the same time, the placement groove of the rack has a fixed shape and cannot adapt to test tubes of different sizes, so it has low adaptability. Utility Model Content

The lifting plate 30 is arranged on the upper side of the sliding plate 20 through the support rod 40, and the support rod 40 is evenly arranged on the end surface of the base 10 and located at the outer circle of the sliding plate 20 (combined with Figure 2 and Figure 3 As shown, in this embodiment, there are four support rods 40 and the four support rods 40 are respectively arranged at the four corners of the outer circle of the sliding plate 20), and a lifting sleeve 31 is arranged on the outer circle of the lifting plate 30 corresponding to the support rod 40, and the lifting sleeve 31 is slidably connected to the outer wall of the corresponding support rod 40.

[0023] The end surface of the sliding plate 20 is rotated by the rotating support 22 to set the positioning seat 23, such as Figure 2 As shown: the rotating support 22 is composed of two parallel support blocks (the bottom end of the support block is fixedly set on the end face of the sliding plate 20), and the corresponding positioning seat 23 is set between the two support blocks, and the outer walls on both sides of the positioning seat 23 are rotatably connected to the corresponding support block through the first rotating shaft 232, and the central axes of the two first rotating shafts 232 are collinear. The positioning seats 23 are evenly distributed on the end face of the sliding plate 20, and a placement groove 231 is opened in the middle of the end face of each positioning seat 23, and a buffer layer is set on the inner wall of the placement groove 231 (the buffer layer can be made of sponge material, rubber material or silicone material and other elastically deformable materials to adapt to the support and clamping of test tubes of different sizes; in addition, the placement groove 231 can also be set to a conical structure with an inner diameter gradually decreasing from top to bottom). The lifting plate 30 has a rotating groove 32 corresponding to the positioning seat 23, and a positioning cylinder 33 is rotatably set in the rotating groove 32, and both sides of the positioning cylinder 33 (i.e. Figure 1 Front and rear sides shown or Figure 2 The outer walls of the left and right sides (shown in FIG. 1 ) are rotatably connected to the corresponding inner walls of the rotating groove 32 through the second rotating shaft 320, and the second rotating shaft 320 and the corresponding first rotating shaft 232 are parallel to each other (as shown in FIG. Figure 2As shown); In addition, in order to ensure the reset between the positioning seat 23 and the positioning cylinder 33 and facilitate the insertion and placement of the test tube (i.e., to avoid the positioning seat 23, the positioning cylinder 32, etc. from rotating at will, causing the test tube to be unable to be accurately inserted), a torsion spring is set on the outer wall of the connection between the first rotating shaft 232 and the rotating support 22, and the outer wall of the connection between the second rotating shaft 320 and the rotating groove 32 (the torsion spring is respectively collinear with the corresponding first rotating shaft 232 and the second rotating shaft 320 center axis, and the torsion spring can be a conventional product in the field). The inner diameter of the positioning cylinder 33 is collinear with the center line of the corresponding placement groove 231 (in the initial state, it is ensured that the initial center axis of the inserted culture test tube 50 is vertical, as shown in FIG. Figure 1 or Figure 2 As shown), an elastic clamping mechanism is provided on the inner wall of the positioning cylinder 33, and the test tube is firmly clamped by the elastic clamping mechanism of the positioning cylinder 33 and the placement groove 231; Figure 4 As shown, the elastic clamping mechanism includes a telescopic spring 331 and an arc-shaped clamping block 332. There are two arc-shaped clamping blocks 332 in the same positioning cylinder 33, and they are symmetrically arranged about the central axis of the positioning cylinder 33 (refer to Figure 4 As shown, the two arc-shaped clamping blocks 332 are respectively arranged at Figure 4 The left and right sides and the second rotating shaft 330 shown in the figure are arranged on the upper and lower sides, that is, the arc-shaped clamping block 332 is in a different orientation from the second rotating shaft 330, ensuring that the arc-shaped clamping block 332 supports and fixes the culture test tube 50 in the rotating direction during the rotation of the positioning cylinder 33 around the second rotating shaft 330; the two arc-shaped clamping blocks 332 protrude in the direction away from each other) and the center line of the two arc-shaped clamping blocks 332 is perpendicular to the corresponding central axis of the second rotating shaft 330, and the ends (end faces) of the arc-shaped clamping blocks 332 that are away from each other are fixedly connected to the corresponding inner wall of the positioning cylinder 33 through the telescopic spring 331 (the number of the telescopic springs 331 can be set according to actual conditions, combined with Figure 1 and Figure 4 As shown, in this embodiment, two rows of telescopic springs 331 are arranged on the same arc-shaped clamping block 332, with two telescopic springs 331 in each row).

[0024] like Figure 3 , Figure 4 As shown, the length of the rotating groove 32 is greater than its width, thereby ensuring that the angle of the test tube slope can be adjusted in a wide range.

[0025] Embodiment 2:

[0026] As a further optimization of the solution of the utility model, in order to simultaneously ensure the positioning and adjustability of the lifting plate 30, on the basis of the solution of Example 1, a plurality of positioning holes are evenly arranged on the support rod 40 and along its axial direction, and a through hole is correspondingly provided in the lifting sleeve 32, and the positioning of the lifting plate 30 in the height direction is achieved by inserting the positioning pins into the through holes and the corresponding positioning holes in sequence; in addition, a limit block is coaxially arranged at the top of the support rod 40, and the outer diameter of the limit block is larger than the outer diameter of the lifting sleeve 32, thereby preventing the lifting plate 30 from sliding out of the support rod.

[0027] Working principle:

At this time, the positioning cylinder 33 rotates in the corresponding rotating groove 32 through the second rotating shaft 330, and the positioning seat 23 rotates in the corresponding rotating support 22 through the first rotating shaft 232 (in this process, the torsion springs on the first rotating shaft 232 and the second rotating shaft 330 are compressed), thereby realizing the inclination of the culture test tube 50 to ensure the formation of the test tube inclined surface, see Figure 5 As shown; when the culture tube 50 reaches a certain angle, the movement of the sliding plate 20 and the lifting plate 30 is stopped, and the positioning pin is inserted into the corresponding through hole of the lifting sleeve 32 and the corresponding positioning hole of the support rod 40 to achieve the fixed positioning of the lifting plate 30 and ensure the stability of the angle of the test tube slope. The setting of the telescopic spring 331 and the arc-shaped clamping block 332 can firmly clamp the culture tubes 50 of different diameters.

[0029] Embodiment 3:

[0030] As a further optimization of the solution of the utility model, on the basis of the solution of Example 1, in order to ensure the stability of clamping, the inner side wall of the arc-shaped clamping block 332 is provided with criss-crossing rubber ridges, thereby increasing the friction between the arc-shaped clamping block 232 and the outer wall of the culture tube 50.
