DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figure 1-8 The utility model provides a technical solution: a biological reagent mixing device, including an installation box 1, and also including:

[0039] A fixing unit 4, arranged at the upper end of the installation box 1, for fixing the sample tube;

[0040] The fixing unit 4 comprises:

[0041] A fixing seat 41 is arranged at the upper end of the installation box 1;

[0042] A clamping block 44 is arranged on the fixing seat 41 and can be adjusted at an equal angle to fix the test tube;

[0043] An adjusting device 42, which is disposed on the fixing seat 41 and connected to the clamping block 44, and is used to adjust the installation position of the clamping block 44;

[0044] The power unit 2 is arranged on the installation box 1 and connected to the fixing base 41, and is used for driving the fixing base 41 to shake.

[0045] It should be noted that, when working, the test tube containing the detection liquid is placed on the fixing seat 41, and then the adjusting device 42 is rotated. Since the adjusting device 42 is meshed and connected with the clamping block 44, the adjusting device 42 can drive the multiple clamping blocks 44 to move inward during the rotation to clamp and fix the test tube. After the test tube is installed, the power unit 2 is turned on, so that the power unit 2 drives the fixing seat 41 to shake. By setting up this device, test tubes of different sizes can be fixed conveniently, so that test tubes of different sizes can be mixed and used, thereby improving the practicability of the entire device, and can improve the mixing efficiency of the detection liquid and reduce labor costs.

[0046] In one embodiment, the adjusting device 42 includes a rotating block 423 rotatably inserted into the fixed seat 41, an inserting block 421 inserted into the rotating block 423, a rotating disk 422 fixed to a side of the inserting block 421 away from the rotating block 423, and a transmission member for transmission arranged on a side of the rotating block 423 located in the fixed seat 41, and the transmission member is connected to the clamping block 44;

[0047] A plug hole 415 for the rotating block 423 to rotate is formed at a position of the fixing seat 41 corresponding to the rotating block 423 .

[0048] In this design, the turntable 422 is rotated so that the inserting block 421 drives the rotating block 423 to rotate inside the inserting hole 415, and then the transmission member drives the clamping block 44 to move on the fixing seat 41, and then the clamping block 44 fixes the test tube.

[0049] In one embodiment, the transmission member includes a transmission gear 424 fixed on the rotating block 423, a gear plate 43 rotatably inserted into the fixed seat 41, a connecting gear 432 fixed at the lower end of the gear plate 43, and a helical gear 431 fixed at the upper end of the gear plate 43, and the transmission gear 424 is meshed and connected with the connecting gear 432;

[0050] A mounting groove 412 for the gear plate 43 to move is formed at a position of the fixing seat 41 corresponding to the gear plate 43 .

[0051] With this design, the rotating block 423 rotates, causing the transmission gear 424 to mesh with the connecting gear 432, and driving the gear plate 43 to rotate inside the mounting groove 412. The spiral gear 431 at the upper end of the gear plate 43 is connected to the clamping block 44, driving the clamping block 44 to perform a gathering movement, thereby fixing the test tube. After the test tube is fixed, the insert block 421 is pulled out from the inside of the rotating block 423.

[0052] In one embodiment, an adjusting gear 442 meshing with the helical gear 431 is disposed at a position of the clamping block 44 corresponding to the helical gear 431, and a moving groove 411 for the clamping block 44 to move is opened at a position of the fixing seat 41 corresponding to the clamping block 44;

[0053] A positioning groove 414 for placing a test tube is provided in the middle of the upper end of the fixing seat 41;

[0054] A connecting groove 441 matching with the moving groove 411 is provided at a position of the clamping block 44 corresponding to the moving groove 411;

[0055] The upper end of the clamping block 44 is provided with a mixing tank 443 for placing the test tube;

[0056] A wear-resistant block 444 is disposed on one side of the clamping block 44 located inside the positioning groove 414 .

[0057] With such a design, when the diameter of the test tube is large, the test tube is placed inside the positioning groove 414, and when the rotating block 423 drives the gear plate 43 to rotate, the spiral gear 431 engages with the adjusting gear 442, driving the clamping block 44 to move toward the inside of the positioning groove 414, and fixes the test tube placed inside the positioning groove 414. The wear-resistant block 444 arranged on the inner side of the clamping block 44 can increase the friction between the clamping block 44 and the test tube, and can improve the stability of the test tube installation. When the diameter of the test tube is small, the test tube is placed inside the mixing groove 443, and the clamping block 44 collides with the test tube to mix the detection reagents inside the test tube. There are multiple mixing grooves 443, and multiple test tubes can be mixed at the same time, thereby improving the mixing efficiency of the detection reagents.

[0058] In one embodiment, a placement groove 413 is provided at the lower end of the fixed seat 41 for placing the rotating block 423 and connected to the installation groove 412. A support ring 45 is provided inside the installation groove 412 for supporting the rotating block 423. A limit ring 451 that is slidably connected to the rotating block 423 is provided at the position of the support ring 45 corresponding to the rotating block 423. A limit groove 4231 for the limit ring 451 to move is provided at the position of the rotating block 423 corresponding to the limit ring 451.

[0059] With this design, the limiting ring 451 is connected to the limiting groove 4231 on the rotating block 423 , so that the rotating block 423 can rotate inside the insertion hole 415 , and the rotating block 423 can be installed more stably inside the fixing seat 41 .

[0060] In one embodiment, the power unit 2 includes a motor 21 fixed inside the installation box 1, a rotating shaft 22 arranged at the power output end of the motor 21, and a connecting member 23 arranged on the installation box 1 and connected to the rotating shaft 22, and a connecting seat 3 for fixing the fixing seat 41 is arranged at the upper end of the connecting member 23;

[0061] The connecting member 23 includes a bearing seat 231 rotatably arranged on the installation box 1, a rotating disk 232 fixed to the upper end of the rotating shaft 22 and connected to the bearing seat 231, and an eccentric block 233 eccentrically arranged at the upper end of the rotating disk 232 and connected to the connecting seat 3. The outer side of the connecting seat 3 is connected to the installation box 1 through an elastic device 24.

[0062] The elastic device 24 includes a limiting bolt 241 fixed on the installation box 1 and an elastic member 242 sleeved on the limiting bolt 241 and fixed between the installation box 1 and the connecting seat 3. The elastic member 242 is made of a spring with a damper or an elastic gasket.

[0063] With this design, the motor 21 rotates, so that the rotating shaft 22 drives the rotating disk 232 to rotate, so that the eccentric block 233 drives the connecting seat 3 to rotate along the bearing seat 231, and so that the connecting seat 3 drives the fixed seat 41 to rotate, thereby mixing the detection reagents inside the test tube, and under the action of the limit bolt 241 and the elastic member 242, the connecting seat 3 can be elastically shaken during the movement, thereby increasing the swing amplitude of the fixed seat 41, thereby improving the mixing efficiency of the sample.

[0064] In addition, if there are descriptions involving "first", "second", etc. in the embodiments, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying the importance of the relative description or implicitly indicating the number of the indicated technical features.
