Description

Technical Field

[0001] The utility model relates to the technical field of test tube storage devices, and particularly relates to a test tube rack that is convenient to carry and move. Background Art

[0002] A test tube rack is an essential basic experimental instrument in a chemical laboratory, and its main function is to place and dry test tubes;

[0003] Test tube racks are usually made of materials such as wood, bamboo, or metal, and are designed in various specifications to meet different experimental needs. For example, the Chinese utility model patent disclosed under the publication number CN218012862U: A portable test tube rack. In this application, the annular platforms on the rotating rod cooperate with the clamping platforms and the inner annular grooves on the base respectively to fix the clamping platforms and the base. After a set of clamping platforms and the base are fixed, test tubes can be installed through the installation holes and fixing grooves, and clamping platforms and bases at different heights can be installed according to the height of the test tubes through annular platforms at different heights. At the same time, when not in use, the clamping platforms and the base can be disassembled respectively, reducing the overall occupied volume and being convenient to carry. Also, multiple groups of test tubes can be installed by rotating the angles between different groups of clamping platforms and bases, solving the problem that traditional test tube racks are not convenient to carry and not suitable for use when working outdoors. Although this application can fold and store the overall structure of the test tube rack, when storing and carrying test tubes, the overall unfolded structure size of this application is relatively large, which is not conducive to carrying. Additionally, when storing test tubes through this application, most of the tube bodies of the test tubes will be placed between the clamping platforms and the base, resulting in the tube bodies of the test tubes being directly exposed outside, and it is easy for the test tubes to collide with external objects during carrying, thus causing the test tubes to be damaged. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a test tube rack that is convenient to carry and move, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4 shown, a test tube rack that is convenient to carry and move provided by the present utility model includes a base 1. A top cylinder 2 is fixedly installed on the top of the base 1. An end cover 3 is movably installed on the top of the top cylinder 2. A plurality of protective sleeves 4 are arranged on the outside of the top cylinder 2. A fixing seat 5 is fixedly installed on the outside of the protective sleeve 4. The protective sleeve 4 is movably installed on the outside of the top cylinder 2 through the fixing seat 5.

[0022] A connecting groove 6 is opened in the base 1. A fixing block 7 is fixedly installed at the center of the bottom of the connecting groove 6. A screw groove 8 is opened at the top of the fixing block 7. By providing the fixing block 7 in the base 1 and opening the screw groove 8 at the top of the fixing block 7, it can provide a basic condition for installing the end cover 3 to the top of the top cylinder 2. A plurality of slots 9 are also opened in the base 1 at the peripheral position of the top cylinder 2. A rubber ring 10 is fixedly installed inside the slot 9. By opening the slot 9 and cooperating with the rubber ring 10 inside the slot 9, the lower half of the test tube can be stably inserted and installed in the slot 9;

[0023] As Figures 2-4As shown in the figure, a plurality of sliding grooves 11 are formed on the outer side of the top cylinder 2. The number of the sliding grooves 11 is equal to the number of the insertion slots 9. A jack 12 is formed at the bottom of the inner part of the sliding groove 11. A screw rod 13 is fixedly installed at the center of the bottom of the end cover 3. The bottom of the screw rod 13 passes through the top cylinder 2 and extends into the connecting groove 6 and is threadedly connected to the screw groove 8. The end cover 3 is placed on the top of the top cylinder 2. Through the arrangement of the end cover 3, the upward movement of the protective sleeve 4 can be limited. A pressing plate 14 is fixedly installed on one side of the protective sleeve 4 away from the fixed seat 5. A sliding block 15 is fixedly installed on one side of the fixed seat 5. A guide shaft 16 is fixedly installed at the bottom of the sliding block 15. The protective sleeve 4 is inserted and installed on the outer side of the top cylinder 2 through the fixed seat 5. The sliding block 15 is slidably installed in the sliding groove 11. The bottom of the guide shaft 16 is inserted into the jack 12. A compression spring 17 is sleeved on the guide shaft 16 between the sliding block 15 and the bottom of the inner part of the sliding groove 11. The bottom of the protective sleeve 4 is movably connected to the top of the base 1 of the test tube through a corrugated pipe 18. And the top of the insertion slot 9 is placed inside the corresponding corrugated pipe 18. Through the arrangement of the protective sleeve 4 that can be pressed and moved downward, it is convenient to expose the end of the test tube, so as to facilitate the extraction of the test tube from the protective sleeve 4 and the insertion slot 9. And the arrangements of the protective sleeve 4 and the insertion slot 9 can provide comprehensive protection for the stored test tubes.

[0024] It should be noted that the present utility model is a test tube rack that is convenient to carry and move. When storing test tubes, the bottom of the test tube can pass through the protective sleeve 4 and the corrugated pipe 18 and be inserted into the insertion slot 9, so as to use the rubber ring 10 in the insertion slot 9 to squeeze and fix the lower half of the test tube. And the top of the test tube is placed inside the protective sleeve 4. Thus, the test tube can be comprehensively protected by the protective sleeve 4, the corrugated pipe 18 and the insertion slot 9, preventing the test tube from being damaged by hitting external objects when storing and carrying the test tube through the base 1 and the top cylinder 2. When the test tube needs to be taken out, the pressing plate 14 on one side of the corresponding protective sleeve 4 can be pressed downward. Then, the pressing plate 14 drives the protective sleeve 4 and the fixed seat 5 to move downward synchronously, and the fixed seat 5 drives the sliding block 15 to move downward in the corresponding sliding groove 11. At the same time, the sliding block 15 moves the guide shaft 16 downward in the jack 12, and the sliding block 15 also compresses the compression spring 17 toward the bottom of the jack 12. Then, the protective sleeve 4 compresses the corrugated pipe 18 toward the top of the base 1, so that the top of the test tube can be exposed after the protective sleeve 4 moves downward. Thus, the test tube can be extracted from the insertion slot 9 through the top of the test tube. Then, when the pressing plate 14 is released, the sliding block 15 can be jacked up by the acting force of the compression spring 17 stretching and rebounding, so as to cooperate with the fixed seat 5 to make the protective sleeve 4 move upward and reset.

[0025] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
