[0002] In water quality testing experiments, test tubes are commonly used laboratory equipment, and test tube racks are used to hold test tubes for convenient experimental operations. Currently, most existing test tube racks have a simple structure, typically consisting of multiple holes in a base for placing test tubes. However, this traditional test tube rack has several shortcomings. Because test tubes of different sizes vary in diameter, the fixed hole size of traditional test tube racks makes it difficult to accommodate test tubes of various sizes, significantly limiting their usability. Furthermore, the lack of effective fixation after the test tubes are placed in the holes makes them prone to shaking during movement or collisions, potentially leading to tipping over, breakage, and disruption of the experiment, possibly even resulting in the loss of experimental samples. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Please see Figures 1-5 The diagram shows a test tube rack for water quality testing, comprising a base 1. The base 1 serves as the fundamental support component of the entire test tube rack, providing an installation and load-bearing platform for all other components. The stability of its overall structure directly affects the performance of the test tube rack. The base 1 has multiple cylindrical countersunk holes 2, which are the main spaces for placing test tubes. Their number and layout are set according to actual usage requirements. The multiple countersunk holes 2 allow for the simultaneous placement of multiple test tubes.

[0029] A set of springs 3 is installed in the countersunk hole 2. The springs 3 are the key components that provide elastic clamping force. The set of springs 3 are symmetrically fixed on the inner wall of the countersunk hole 2. This symmetrical arrangement can ensure that the clamping force applied to the test tube is balanced. Each spring 3 is equipped with a test tube clamp 4. The elastic force of the spring 3 is transmitted to the test tube through the test tube clamp 4. The test tube clamps 4 installed on the two springs 3 are symmetrically arranged and work together on both sides of the test tube to achieve clamping of the test tube.

[0030] The test tube clamp 4 includes a connecting part 401, an enlarged bending part 402, and an upper protective part 403. These three parts are integrally molded, ensuring the overall structural strength of the test tube clamp 4 and preventing damage. The outer wall of the connecting part 401 is fixedly connected to the end of the spring 3 away from the inner wall of the countersunk hole 2. The connecting part 401 acts as a bridge between the spring 3 and the test tube clamp 4, effectively transmitting the force of the spring 3 to the entire test tube clamp 4. The side of the connecting part 401 away from the inner wall of the countersunk hole 2 is arc-shaped. This arc-shaped design allows for better contact with the arc-shaped outer wall of the test tube, increasing the contact area, improving clamping stability, and preventing damage to the test tube due to excessive local pressure during clamping. The side of the upper protective part 403 away from the inner wall of the countersunk hole 2 is arc-shaped. The upper protective part 403 is located at the top of the test tube. In addition to assisting in clamping, it also protects the upper part of the test tube during placement and removal, preventing the test tube from colliding with the edge of the countersunk hole 2 or other objects. The diameter-expanding bending part 402 connects the connecting part 401 and the upper protective part 403. Its outward bending structure forms a guide channel with a gradually widening entrance. When the test tube is placed, it can guide the test tube smoothly into the clamping area of ​​the connecting part 401, avoiding jamming or displacement when the test tube is placed.

[0031] A buffer pad 5 is provided at the bottom of the countersunk hole 2. When the test tube is placed into the countersunk hole 2 and falls to the bottom, the buffer pad 5 can absorb the impact force of the test tube falling, avoid the bottom of the test tube from directly colliding with the hard bottom of the countersunk hole 2 and causing the test tube to break, and play an effective protective role for the bottom of the test tube.

[0032] The countersunk holes 2 are arranged in a rectangular array on the base 1. This arrangement makes the multiple countersunk holes 2 neatly and orderly distributed on the base 1, which not only makes it convenient for the experimenters to number and manage the test tubes, but also makes it easy to quickly find the required test tubes during the experiment, thus improving the efficiency of the experiment.

[0033] A ventilated groove 6 is provided between two adjacent countersunk holes 2. The depth of the ventilated groove 6 is greater than the depth of the countersunk hole 2, and the ventilated groove 6 provides the main channel for air circulation. The outer wall of the countersunk hole has multiple ventilated holes 7 that communicate with the ventilated groove 6. The ventilated holes 7 connect the internal space of the countersunk hole 2 with the ventilated groove 6, allowing external air to enter the interior of the countersunk hole 2 through the ventilated groove 6 and the ventilated holes 7. At the same time, the air inside the countersunk hole 2 can also be discharged through the ventilated holes 7 and the ventilated groove 6, realizing the circulation of air inside and outside the countersunk hole 2. This is beneficial for the ventilation and drying of samples in the test tube, and is especially suitable for experimental scenarios that require sample ventilation.

[0034] A set of sliding components 8 is symmetrically arranged at the bottom of the base 1, providing convenient structural support for the movement of the test tube rack. The sliding components 8 include an upper U-shaped channel steel 801, a lower U-shaped channel steel 802 disposed in the external storage cabinet, and rollers 803 with shafts. The bottom end face of the upper U-shaped channel steel 801 is rigidly connected to the lower end face of the base 1, allowing the upper U-shaped channel steel 801 to firmly drive the base 1 to move. Multiple rollers 803 are arranged in an array in the grooves of the upper U-shaped channel steel 801. The rollers 803 can rotate flexibly, converting sliding friction into rolling friction, greatly reducing friction during movement. The groove width of the lower U-shaped channel steel 802 is greater than the outer wall width of the upper U-shaped channel steel 801, and the upper U-shaped channel steel 801 is nested into the groove of the lower U-shaped channel steel 802. The lower U-shaped channel steel 802 provides a track for the upper U-shaped channel steel 801 and the roller with shaft 803 to move, and also plays a guiding and limiting role to prevent the test tube rack from shifting during movement. At the same time, the roller on the roller with shaft 803 contacts the bottom end face of the groove of the lower U-shaped channel steel 802. When the test tube rack is pushed or pulled, the roller with shaft 803 rolls on the bottom end face of the groove of the lower U-shaped channel steel 802, driving the upper U-shaped channel steel 801 and the base 1 to move smoothly along the track of the lower U-shaped channel steel 802, making it convenient to push the test tube rack into or pull out of the external storage cabinet.

[0035] A handle groove 9 is provided on one side of the base 1. The handle groove 9 provides storage space for the pull-out handle 10. When the pull-out handle 10 is not in use, it can be stored in the groove, preventing the pull-out handle 10 from protruding and causing bumps or taking up extra space. A pull-out handle 10 is provided in the handle groove 9. When it is necessary to move the test tube rack, the pull-out handle 10 can be pulled out from the handle groove 9. Experimenters can easily carry or move the test tube rack by holding the pull-out handle 10, which improves the convenience of moving the test tube rack.

[0036] Working principle:

[0037] When placing the test tube, insert it from above the countersunk hole 2. The test tube first contacts the enlarged-diameter bend 402 of the test tube clamp 4. Due to the structural design of the enlarged-diameter bend 402, it guides the test tube, facilitating its smooth entry. As the test tube moves downward, it presses against the connecting parts 401 on both sides. The pressure on the connecting parts 401 compresses the spring 3, and the reaction force generated by the spring 3 acts on the test tube through the test tube clamp 4, thus clamping and fixing the test tube to prevent it from shaking. The bottom of the test tube contacts the buffer pad 5 at the bottom of the countersunk hole 2. The buffer pad 5 acts as a cushion, preventing damage caused by hard contact between the bottom of the test tube and the countersunk hole 2.

[0038] In terms of ventilation, the vent holes 7 on the outer wall of the counterbore 2 are connected to the vent grooves 6 between adjacent counterbores 2. Air can circulate inside and outside the counterbore 2 through the vent grooves 6 and vent holes 7, thereby achieving ventilation and air exchange for the sample in the test tube, which is beneficial for the drying or ventilation treatment of the sample.

[0039] When the test tube rack needs to be moved, the pull handle 10 in the handle groove 9 can be pulled out, and the test tube rack can be moved conveniently by pulling the handle 10. If the test tube rack is to be pushed into or pulled out of the external storage cabinet, the sliding component 8 at the bottom of the base 1 will come into play. The upper U-shaped channel steel 801 is nested in the groove of the lower U-shaped channel steel 802, and the roller 803 with shaft rolls on the bottom end face of the groove, reducing the friction during movement and making the push and pull of the test tube rack smoother and less effort.

[0040] The embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
