Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, and in particular relates to a test tube rack with a protective structure. Background Technology

[0002] In laboratories, test tube racks are commonly used experimental equipment, mainly used to store and secure test tubes for various experimental operations. Existing test tube racks typically consist of a support frame and insert plates. The insert plates have an array of test tube insertion holes, into which the test tubes are inserted for fixation.

[0003] However, existing test tube racks have some shortcomings in use. On the one hand, existing test tube racks lack protective measures for the bottom of the test tubes. After the test tubes are inserted into the sockets, the bottoms are in direct contact with the insert plates or support frames. When placing heavy test tubes or conducting experiments with significant vibration, the bottoms of the test tubes are easily damaged by impact. On the other hand, when the test tube rack is impacted, shaken, or placed on uneven surfaces, the lack of restraint structures at the bottom of the test tubes makes them prone to tilting, falling over, or even detaching from the sockets, causing reagents to spill. This can not only affect experimental results but also pose safety hazards to experimental personnel and equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a test tube rack with a protective structure to solve the problems of test tubes easily tilting, falling over, falling off, easily breaking at the bottom, and inconvenient replacement of parts during the use of common test tube racks.

[0006] Furthermore, the support frame is an integrally formed structure consisting of a horizontal plate and two vertical plates. A clamping plate is fixedly provided on the inner side of the vertical plate, and several spherical snap-fit ​​protrusions are fixedly provided on the inner wall of the vertical plate above the clamping plate. Long through holes are opened on the two vertical plates to reduce weight.

[0007] Furthermore, the bottom of the square box is provided with a first slot, the horizontal plate is inserted into the first slot, the internal space of the square box has a structure with a raised middle and recessed sides at the corresponding position of the first slot, and the shape of the sponge block corresponds to the internal space structure of the square box.

[0008] Furthermore, the horizontal plate engages with the first slot without the need for screws, facilitating quick separation of the square box from the support frame for sponge block replacement.

[0009] Furthermore, the anti-tilt frame includes three-section slats, the bottom end of which is fixedly connected to the square box, and the other end of which is provided with an arc-shaped groove that connects to the outer wall of the test tube. The top of the sponge block is provided with several columnar grooves for the bottom of the test tube to be inserted into.

[0010] Furthermore, the anti-tipping brackets are divided into two groups and set on both sides of the square box. The arc-shaped grooves abut against the test tubes from the outside to prevent them from tilting and falling over. The shallow columnar grooves provide partial support for the test tubes to prevent them from slipping. The sponge blocks have a cushioning effect to prevent the test tubes from sinking under gravity and colliding with the bottom of the square box.

[0011] Furthermore, the lower part of both ends of the insert plate is provided with a second slot, the insert plate is inserted into the second slot, and a plurality of hemispherical slots are provided above the second slot, the spherical locking protrusions are engaged with the hemispherical slots.
