Description

Technical Field

[0001] The invention relates to a freezing tube box, in particular to a freezing tube box with a convenient box cover to open and close. Background Art

[0002] At present, freezing boxes, as a device for fixing and storing cryotubes, are widely used in biological and medical experiments. However, the test tube boxes used for medical examinations in hospitals are all flat, which makes it inconvenient for doctors to take them, especially when medical services are busy. This not only wastes a lot of time and reduces work efficiency, but also due to the urgency of time, the cryotubes may break due to taking them too quickly. At the same time, during transportation, the cryotubes may also fall off due to shaking. In order to solve the problem of taking out the freezing box in the prior art, a plurality of lifting plates arranged in rows are arranged on the bottom wall inside the freezing box, and a shifting block is provided on the side wall of the freezing box, which is connected to the lifting plate. When taking out the freezing box, the shifting block is lifted to bring the lifting plate up so that the frozen tubes in this row are higher than other test tubes, so that the desired frozen tube can be taken out conveniently. However, in this way, each time the doctor extracts the frozen tubes, a row of frozen tubes must be raised in advance. This not only easily causes the risk of other frozen tubes falling when taking them out, but also makes it impossible to quickly and accurately get the frozen tubes you need. At the same time, it also cannot ensure the stability of the frozen tubes in the box body, which easily causes the problem of falling off. Summary of the invention

[0003] In view of the above problems, the present invention aims to provide a freezing tube box with a convenient box cover to open and close, which has a stable and reliable structure, a novel and unique way of opening and closing the box cover, and is easy to operate.

[0004] The technical solution of the present invention is a freezing pipe box with a convenient box cover for opening and closing, comprising a base and a box cover, wherein a series of positioning holes for inserting freezing pipes are arranged on the base in the horizontal and vertical directions, and the characteristics are as follows: positioning holes are arranged vertically on the left and right sides of the base, positioning blocks are extended downward from the inner sides of the bottom of the positioning holes, operating holes are arranged at the box cover corresponding to the positioning holes, a hook is extended downward from the inner sides of the operating holes, a handle is arranged at the operating hole, a pull rod inserted into the operating hole is extended downward from the bottom of the handle, a curved hook is extended downward from the outer sides of the bottom of the pull rod, the bottom of the curved hook is bent inwardly and extends to hook the bottom surface of the hook to prevent the handle from falling out, a hook head is extended from the inner side of the hook, and a protrusion is extended from the outer side; When the box cover is closed on the base, the handle is inserted downward into the operating hole and the inner wall of the pull rod abuts against the protrusion to cause the hook to deform inward so that the hook head hooks on the bottom surface of the positioning block to connect the box cover and the base together; Pull up the handle so that the protrusion is separated from the inner wall of the pull rod and enters the avoidance cavity of the hook, so that the hook returns to the initial state and ensures that the hook head is separated from the positioning block so that the box cover and the base are separated.

[0005] Preferably, two front and rear positioning holes are respectively provided on the left and right sides of the base, and two front and rear operating holes and hooks are also correspondingly provided on the left and right sides of the box cover. Two front and rear pull rods are correspondingly provided at the bottom of the handle. Each set of pull rods, hooks, and positioning blocks cooperate with each other, and the box cover and the base are separated or connected by lifting or pressing the handle.

[0006] Preferably, the freezing tube comprises a tube body and a tube cover which are threadedly connected, the tube body comprises a transparent base portion and a solid color identification portion, the tube body is formed by two-color injection molding, and the identification portion is provided with a barcode or a QR code of different colors.

[0007] Preferably, the base, lid, handle and freezing tube are all made of cold-resistant modified PP.
