Description

Technical Field

[0001] This application relates to the field of mixing device technology, specifically to a test tube fixing structure for a mixing device. Background Technology

[0002] Mixing reagent tubes is a routine operation in the medical and biological fields. Common mixing devices on the market include rotary sample mixers, vibratory sample mixers, and stirring sample mixers. Rotary sample mixers rotate the test tube to rotate the reagent inside, thereby creating a vortex that mixes the sample with the reagent.

[0003] Because test tubes come in various sizes on the market, some rotary sample mixing devices use a test tube fixing structure that can only limit and mix a single test tube. This means that when there is a large demand for certain reagents, a large number of test tubes need to be loaded in batches for mixing, resulting in low overall operating efficiency. If a large amount of the current reagent needs to be mixed, a mixing device corresponding to a large-capacity container needs to be purchased, which increases costs. Utility Model Content

[0004] Therefore, this application provides a test tube fixing structure for a mixing device to solve the problem that the prior art can only accommodate test tubes of a single size for positioning.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A test tube fixing structure for a mixing device, comprising:

[0007] The mounting block has a constraint band installed on its inner side and several limiting protrusions fixed at equal intervals on the outer side of the constraint band. A limiting rod is provided on one side of the mounting block. An mounting rod is installed on the inner side of the limiting rod and a limiting block is slidably connected to the outer side of the mounting rod. The limiting block and the limiting protrusions form a snap-fit ​​connection.

[0008] The middle part of the limiting rod is threadedly connected to a tightening rod, and one end of the tightening rod is rotatably connected to the mounting block;

[0009] The upper surface of the mounting block is also fixed with a lower placement plate, and the upper side of the lower placement plate is threaded with a connecting rod, and the upper end of the connecting rod is fixed with an upper limit plate.

[0010] Optionally, the mounting block has a hole-like structure corresponding to the constraint band on its inner side, and the inner side of the hole-like structure is inclined.

[0011] Optionally, both sides of the limiting protrusion are inclined, and the inclination directions of both sides are the same.

[0012] Optionally, the inclination direction of the outer side of the limiting block is the same as the inclination direction of the limiting protrusion.

[0013] Optionally, a gasket is also provided on the side of the mounting block facing the constraint band.

[0014] Optionally, the diameter of the upper limit plate is larger than the diameter of the lower plate.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] 1. By utilizing the cooperation between the constraint strap and the mounting block, the constraint strap can fit against the outer surface of containers of different sizes, thereby limiting the size of containers and facilitating the control of large-capacity containers for mixing.

[0017] 2. By using the tightening rod and the limiting rod, the constraint band can be tightened again, thereby avoiding poor adhesion between the constraint band and the outer wall of the test tube, which may cause the test tube to detach from the constraint band during the mixing process.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides a test tube fixing structure for a mixing device, including a mounting block 1. A constraint band 2 is installed on the inner side of the mounting block 1, and several limiting protrusions 3 are fixed at equal intervals on the outer side of the constraint band 2. A limiting rod 4 is provided on one side of the mounting block 1, and a mounting rod 5 is installed on the inner side of the limiting rod 4. A limiting block 6 is slidably connected to the outer side of the mounting rod 5. The limiting block 6 and the limiting protrusions 3 form a snap-fit ​​connection, so that after the constraint band 2 is inserted into the limiting rod 4, the limiting protrusions 3 and the limiting block 6 snap-fit, thereby positioning the constraint band 2. After adjustment according to test tubes of different sizes, the constraint band 2 fits the test tube. The constraint band 2 can fit the outer wall of test tubes of different shapes, increasing adaptability.

[0026] The middle part of the limiting rod 4 is threadedly connected to the tightening rod 7, and one end of the tightening rod 7 is rotatably connected to the mounting block 1;

[0027] Specifically, when the constraint band 2 is positioned using the interlocking structure between the limiting protrusion 3 and the limiting block 6, there will inevitably be a gap between the limiting protrusion 3 and the limiting block 6 for the insertion of the limiting block 6. This can easily lead to poor adhesion between the constraint band 2 and the outer wall of the test tube, which may cause the test tube to detach from the constraint band 2 during the mixing process.

[0028] Therefore, the tightening rod 7 is used to reinforce the adhesion between the constraint band 2 and the outer wall of the test tube. After the constraint band 2 is in contact with the outer wall of the test tube, the tightening rod 7 is rotated so that the limiting rod 4 continues to tighten the constraint band 2 while it is engaged with the constraint band 2, thereby increasing the adhesion between the constraint band 2 and the outer wall of the test tube and preventing it from falling off.

[0029] The mounting block 1 has a hole-like structure on its inner side that corresponds to the constraint band 2, and the inner side of the hole-like structure is inclined to accommodate the outward expansion of the constraint band 2 and prevent the contact position between the constraint band 2 and the mounting block 1 from breaking due to excessive bending.

[0030] Both sides of the limiting protrusion 3 are inclined, and the inclination direction of both sides is the same. The inclination direction of the outer side of the limiting block 6 is the same as the inclination direction of the limiting protrusion 3, which facilitates the insertion of the constraint band 2.

[0031] A gasket 8 is also provided on the side of the mounting block 1 facing the constraint band 2 to prevent the test tube from directly contacting the mounting block 1 and to provide a certain buffer.

[0032] The upper surface of the mounting block 1 is also fixed with a lower placement plate 9. The upper side of the lower placement plate 9 is threaded with a connecting rod 11, and the upper end of the connecting rod 11 is fixed with an upper limit plate 10. The diameter of the upper limit plate 10 is larger than the diameter of the lower placement plate 9.

[0033] Specifically, first insert the lower placement plate 9 into the slot originally reserved for test tube placement inside the mixing device. Then, rotate the connecting rod 11 into the lower placement plate 9 so that the upper positioning plate 10 fits into the reserved slot, preventing the lower placement plate 9 from moving downward and falling off. If the diameter of the lower placement plate 9 is larger than the diameter of the reserved slot, place the lower placement plate 9 under the reserved slot and then rotate the connecting rod 11 into the lower placement plate 9 so that the upper positioning plate 10 and the lower placement plate 9 clamp the placement frame of the mixing device.

[0034] The technical features of the above embodiments can be combined in any way as long as there is no contradiction in the combination of these technical features. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
