DETAILED DESCRIPTION

[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0021] Example

[0022] See also Figure 1-3, the utility model provides a technical solution: a biological experiment tool;

[0023] This case aims to provide a biological experiment tool that is convenient for storing test tubes. The existing test tube openings are exposed and easily contaminated, and the reagent rack structure is fixed and cannot be adjusted.

[0024] Based on the above problems, the components in this case are mainly base 1, an adjustment structure is installed on the upper side of the base 1, and a limited position structure is set on the upper side of the base 1. The adjustment structure includes:

[0025] A worm 2, two turbines 3, two threaded rods 4, two fixing frames 5, two lifting rods 6, a limiting seat 7, a plurality of openings 8, four limiting slide blocks 9 and four limiting slide grooves 10;

[0026] The interior of the base 1 is set to be hollow, one end of the worm 2 is connected to the inner wall of one side of the base 1 through a bearing, and the other end penetrates the wall of the base 1, two turbines 3 are arranged inside the base 1, the bottom ends of the two threaded rods 4 penetrate the inner wall of the top of the base 1 and are connected to the two turbines 3, the bottoms of the two fixing frames 5 are connected to the top of the base 1, the bottoms of the two lifting rods 6 are threadedly connected to the tops of the two threaded rods 4, the bottom of the limit seat 7 is connected to the tops of the two lifting rods 6, four limit slide grooves 10 are opened on the inner sides of the two fixing frames 5, two limit sliders 9 are installed on the front and rear sides of the two lifting rods 6, and the four limit slide grooves 10 are slidably connected to the four limit sliders 9 respectively;

[0027] The limiting structure includes: a support seat 11, a plurality of arc-shaped grooves 12 and two rotating frames 13;

[0028] The support seat 11 is installed on the top of the base 1, a plurality of arc grooves 12 are opened on the top of the support seat 11, and the lower sides of two rotating frames 13 are rotatably connected to the two sides of the top of the support seat 11;

[0029] It should be noted that, during use, the worm 2 is first rotated according to the length of the test tube, and then the worm 2 cooperates with the turbine 3 and the threaded rod 4 to push the lifting rod 6 to move in the vertical direction, so that the distance between the limit seat 7 and the support seat 11 matches the test tube. At this time, the upper side of the test tube is inserted into the opening 8 at the front end of the limit seat 7, and the lower side of the test tube is inserted into the arc groove 12, and the rotating frame 13 is rotated to connect the two rotating frames 13 to become vertical, and the two rotating frames 13 are connected by four magnetic blocks 16, so that the lower side of the test tube can be clamped and fixed to prevent the test tube from shaking when the operator moves the device as a whole;

[0030] It should be emphasized that the limit slider 9 is slidably connected to the limit slide groove 10, which can increase the stability of the lifting rod 6 during the vertical movement of the lifting rod 6 and prevent the test tube from shaking during the movement of the device;

[0031] Furthermore, since the wall surface of the other end of the worm 2 is smooth, a knob 14 is installed at the other end of the worm 2 to facilitate the operator to rotate the worm 2;

[0032] Furthermore, after the upper side of the test tube is inserted into the opening 8, the upper side of the test tube is still exposed to the air. For this reason, a rubber sealing block 15 is provided on the inner wall of the upper side of the opening 8. After the test tube is inserted, the rubber sealing block 15 is squeezed and elastically deformed, thereby sealing the upper side of the test tube and preventing contamination of the sample reagent inside the test tube.

[0033] Furthermore, after the two rotating racks 13 are connected via the magnetic block 16 , the sponge protective layer will be in close contact with the lower side of the test tube, preventing the rotating rack 13 from contacting the test tube and causing damage to the test tube.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
