Description

Technical Field

[0001] The utility model relates to the technical field of test tube racks, in particular to a sampling test tube rack. Background Art

[0002] The sampling test tube rack is a kind of laboratory equipment, which is mainly used to place and organize sampling test tubes for various experiments or tests.

[0003] However, the prior art has the following defects:

[0004] During laboratory sampling experiments, reagents are placed in different test tubes and placed in test tube racks. Different reagents are placed in different test tube racks for easy identification, while test tubes with the same reagent but different ratios can be placed in the same test tube rack. Because test tube racks have a fixed number of slots, inability to accurately count test tubes can result in many unused slots on the rack, reducing the rack's overall utilization. Utility Model Content

[0005] In order to solve the technical problem that during a sampling experiment, a test tube rack cannot provide a relatively accurate number of fixed grids according to the experimental conditions, resulting in a poor test tube utilization rate, the utility model provides a sampling test tube rack.

[0006] The utility model adopts the following technical solution: a sampling test tube rack, comprising a bottom frame and a top frame, wherein the bottom frame is provided with a first thread groove, the top frame is provided with a second thread groove, the bottom frame is provided with a plurality of arc grooves at equal intervals, and rubber pads are glued in the arc grooves, and the top frame is provided with a plurality of fixing openings at equal intervals and located directly above the arc grooves;

[0007] An adjustment mechanism comprising an outer cylinder, an inner cylinder, and an adjustment unit. One end of the outer cylinder is provided with a threaded slide rail 1, which forms a threaded structure with a threaded groove 1. One end of the inner cylinder is provided with a threaded slide rail 2, which forms a threaded structure with a top frame. The other end of the outer cylinder and the other end of the inner cylinder are connected via the adjustment unit.

[0008] The disassembly mechanism includes a magnet and a disassembly unit. The magnets are fixed around the bottom frame and can attract or repel each other. The disassembly unit is provided around the top frame.

[0009] Through the above technical solution, by adjusting the distance between the bottom frame and the top frame under the action of the adjustment mechanism, it is suitable for test tubes of different lengths in the laboratory, thereby increasing the practicality of the device during use.

[0010] A plurality of bottom racks and top racks can be assembled under the action of the disassembly mechanism so that they can be appropriately placed according to the number of test tubes.

[0011] Moreover, the inner cylinder and the outer cylinder are fixed to the top frame and the bottom frame respectively by means of bolts, and can be disassembled for easier cleaning.

[0012] As a further improvement of the above scheme, the adjustment unit includes a limit groove, a limit block, a storage groove, a spring 1 and a sliding unit, several limit grooves are opened in the outer cylinder, three storage grooves are opened on the inner cylinder, one end of the spring 1 is welded on the limit block, and the other end of the spring 1 is welded in the storage groove, and one end of the limit block can be clamped on the limit groove.

[0013] The above technical solution stabilizes the position between the inner and outer cylinders by inserting the stop block and different stop slots. Furthermore, the elastic potential energy of spring 1 enhances the stability of the inner cylinder within the outer cylinder. Furthermore, the arc-shaped end of the stop block and the arc-shaped stop slot enhance the smoothness of the stop block's movement.

[0014] As a further improvement of the above solution, the sliding unit includes a slider and a slide groove, the adjacent ends of the two sliders are fixed on the limit block, and the two slide grooves are both opened in the receiving groove, and the sliders slide in the slide groove.

[0015] With the above technical solution, the slider slides in the chute, so that the limit block can only move vertically up and down in the outer cylinder, thereby ensuring the stability of the limit block when moving in the outer cylinder and not pulling the spring beyond the deformation force.

[0016] As a further improvement of the above scheme, the disassembly unit includes a movable groove, a second spring, an insert block, a slot and a clamping unit. The movable groove is opened at one end of the top frame away from each other, and the slot is opened at the other end of the top frame away from each other. One end of the second spring is welded in the movable groove, and the other end of the second spring is welded to the insert block, and the insert block can be inserted in the slot.

[0017] With the above technical solution, the insert block can be accommodated in the movable slot, so that when the two top frames are not combined, one end of the top frame is smooth, which makes it easier to clean the outer surface of the top frame. At the same time, slide rails and slide bars are provided under the insert block, so that the insert block can only move along the predetermined wire. This makes the insert block more stable and easy to insert into the slot.

[0018] As a further improvement of the above scheme, the clamping unit includes an inclined groove, an inclined block, a pull plate, a spring three and a magnet. The inclined groove is opened on the insertion block, and the magnet is opened in the slot. Two spring plates are fixed in the magnet, and one end of the spring three is fixed on the spring plate, the other end of the spring three is fixed to one end of the inclined block, and the other end of the inclined block can be inserted in the inclined groove, and one end of the pull plate extends into the magnet and is fixed to the inclined block and is located between the two springs three.

[0019] The above technical solution ensures that the insert is stably inserted into the slot by positioning the inclined block in the inclined slot, thereby making the merging of the two top frames more stable. Furthermore, the configuration of springs three and two allows for merging and unmerging in just one step, enabling quick disassembly and assembly, which also reduces time for medical staff.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model can, through the action of the adjustment mechanism and the disassembly mechanism, on the one hand set the number of fixing ports according to actual needs, and on the other hand quickly realize the disassembly and assembly operations of the top frame, saving some time while improving practicality. Moreover, the outer cylinder and the inner cylinder are connected to the bottom frame and the top frame by means of threads, which also facilitates subsequent cleaning and disinfection operations.
