Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a test tube rack with a protection component. Background Art

[0002] A test tube is a commonly used instrument in chemical analysis and is used as a reaction container for a small amount of reagents. It is used at normal temperature or when heated (preheating should be carried out before heating, otherwise the test tube is likely to burst). Test tubes are divided into various types such as ordinary test tubes, branched test tubes, and centrifuge test tubes. A test tube rack, that is, a test tube holder, is the most basic experimental instrument in a chemical laboratory used to place (sometimes the test tube can also be placed on the test tube rack to observe the phenomenon of a certain experiment) and dry test tubes.

[0003] For traditional test tube racks, test tubes are generally placed upright. By setting a collar to hold the upper port of the test tube, and the bottom of the test tube abuts against the base, the storage of test tubes is realized. Persons engaged in related fields have found in long-term work that if the staff does not handle them gently, this setting is likely to cause the bottom of the test tube to hit the base and be damaged, or the mouth of the test tube to hit the collar and cause damage to the tube mouth, greatly reducing the service life of the test tube. In addition, traditional racks do not have the function of collecting water, and the water droplets attached to the surface of the test tube will flow onto the workbench, bringing great trouble to the staff. Therefore, we propose a test tube rack with a protection component to solve the above problems. Summary of the Utility Model

[0004] The utility model specifically adopts the following technical solutions to achieve the above purposes:

[0005] A test tube rack with a protection component, comprising:

[0006] A water storage box, on both side walls of which circular channels are constructed at equal intervals, and buffer pads are arranged above the circular channels on the outer wall of the water storage box;

[0007] A placement plate, which is obliquely fixed on both sides of the water storage box. The placement plate is located below the buffer pad, and an arc-shaped groove communicating with the circular channels is constructed on its surface;

[0008] Test tubes, which are laid flat in the arc-shaped grooves, and the bottoms of the test tubes abut against the buffer pads;

[0009] A clamping mechanism, which is arranged on the top of the water storage box and is used for clamping and fixing test tubes.

[0010] Furthermore, a drain pipe is communicated with the bottom side of one end of the water storage box, and a valve is installed on the pipe body of the drain pipe.

[0011] Furthermore, the buffer pad is an elastic rubber pad.

[0012] Furthermore, the clamping mechanism includes guide rods fixed at equal intervals on both sides of the top of the water storage box, a pressure plate is slidably sleeved on the surface of the guide rod, the pressure plate corresponds to the position of the arc groove, a mounting plate is fixed on the top of the guide rod, a pull rod is slidably inserted through the surface of the mounting plate corresponding to the position of the pressure plate, the bottom end of the pull rod is connected to the pressure plate, a spring is connected between the bottom surface of the mounting plate and the top surface of the pressure plate, and the spring is sleeved on the surface of the pull rod.

[0013] Furthermore, both ends of the pressing plate are arranged to be inclined downward, and the ends are connected with abutment blocks.

[0014] Furthermore, the resistance block is an elastic rubber block, and a side thereof away from the pressure plate is configured with an arc-shaped notch.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The utility model constructs an arc groove on the inclined placement plate, and uses gravity to slowly slide the test tube to the bottom. The staff can quickly put the test tube in, which improves work efficiency. The design of the arc groove and the buffer pad reduces the impact force of the test tube during the placement process and reduces the possibility of damage. The clamping mechanism is used to fix the position of the test tube after it is in place to avoid shaking of the test tube during storage, which has a good protective effect on the test tube. It is highly practical and worthy of widespread application and promotion. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The present application provides a test tube rack with a protection component, which is mainly used to solve the problems in the prior art that it is easy to cause damage to the bottom of the test tube by hitting the base, or damage to the tube mouth by hitting the collar, greatly reducing the service life of the test tube. In addition, the traditional rack does not have the function of collecting water, and the water droplets attached to the surface of the test tube will flow onto the workbench, bringing great trouble to the staff, and provides the following technical solutions. The following will be combined with Figures 1-4 make a detailed description:

[0024] A test tube rack with a protection component, comprising:

[0025] A water storage box 1, on both side walls of which circular channels 101 are constructed at equal intervals, and buffer pads 2 are arranged above the circular channels 101 on the outer wall of the water storage box 1;

[0026] A placement plate 3, which is fixedly arranged obliquely on both sides of the water storage box 1. The placement plate 3 is located below the buffer pad 2, and an arc-shaped groove 301 communicating with the circular channel 101 is constructed on its surface;

[0027] Test tubes 4 are laid flat in the groove of the arc-shaped groove 301, and the bottom of the test tubes 4 abuts against the buffer pads 2;

[0028] A clamping mechanism 5 is arranged on the top of the water storage box 1. The clamping mechanism 5 is used to clamp and fix the test tubes 4. The clamping mechanism 5 includes guide rods 501 fixedly arranged on both sides of the top of the water storage box 1 at equal intervals. A pressing plate 502 is slidably sleeved on the surface of the guide rods 501. The pressing plate 502 corresponds to the position of the arc-shaped groove 301. An installation plate 503 is fixedly arranged on the top of the guide rods 501. A pull rod 504 is slidably inserted through the surface of the installation plate 503 corresponding to the position of the pressing plate 502. The bottom end of the pull rod 504 is connected to the pressing plate 502. A spring 505 is connected between the bottom surface of the installation plate 503 and the top surface of the pressing plate 502. The spring 505 is sleeved on the surface of the pull rod 504.

[0029] The specific implementation steps and principle description of the test tube 4 rack with the protection component:

[0030] During use, the staff first pulls the lever 504 upward, causing the end of the pressing plate 502 to disengage from the placement plate 3. At this time, the spring 505 is in a compressed state. When placing the test tube 4, the staff gently places the test tube 4 from the upper side of the placement plate 3. The test tube 4 slides down slowly along the inclined arc-shaped groove 301 until it completely enters the arc-shaped groove 301 and its bottom abuts against the buffer pad 2. This can significantly reduce the damage to the test tube 4 caused by direct impact on a hard surface. During this process, any water droplets dripping from the surface of the test tube 4 will flow into the water storage box 1 and will not wet the workbench surface. After confirming that the test tube 4 is stably placed at the bottom of the arc-shaped groove 301 and in contact with the buffer pad 2, release the hand. Under the action of the elastic force of the spring 505, the pressing plate 502 moves downward, and its end can press the tube body of the test tube 4, thereby achieving the purpose of fixing the test tube 4 and preventing the test tube 4 from shaking during storage, playing a better protective role for the test tube 4.

[0031] As Figure 1 shown, in some embodiments, a drain pipe 6 is connected to the bottom side of one end of the water storage box 1, and a valve is installed on the pipe body of the drain pipe 6. More specifically, the purpose of such a design is to facilitate the drainage of the accumulated water in the water storage box 1. By opening the valve on the drain pipe 6, the accumulated water in the water storage box 1 can be smoothly drained, ensuring that the test tube 4 placement rack always remains dry and clean. This design can reduce the possibility of water droplets dripping onto the workbench surface, improving the convenience of operation and work efficiency.

[0032] As Figure 2 shown, in some embodiments, the buffer pad 2 is an elastic rubber pad. More specifically, the elastic rubber pad has good shock absorption performance. When the test tube 4 collides with the rubber pad along the direction of the center of gravity axis, vibrations with a certain frequency will be generated. Due to the vibration damping characteristics of the rubber material, the vibrations excited when there is no external force in the system will gradually decay, which can reduce the impact and damage that the test tube 4 may suffer during placement. At the same time, the rubber pad also has the characteristics of waterproof and easy to clean. In a laboratory environment, it is often necessary to clean and disinfect the equipment. The surface of the rubber pad is relatively easy to clean, will not deform due to water absorption, and will not be corroded due to the use of cleaning agents, making the entire placement rack more durable and practical.

[0033] As Figure 2As shown, in some embodiments, both ends of the pressure plate 502 are arranged to be inclined downward, and the ends are connected to the resistance blocks 506, which are elastic rubber blocks, and the side away from the pressure plate 502 is constructed with an arc-shaped notch. More specifically, the elastic rubber resistance block 506 can provide flexible support when in contact with the test tube 4, reducing the risk of hard collision. This material has good impact resistance and durability, and can withstand repeated use without being easily worn or deformed. The arc-shaped notch of the resistance block 506 is to accommodate test tubes 4 of different diameters while reducing damage to the surface of the test tube 4. The arc-shaped edge of the notch allows the resistance block 506 to form an inclusive contact when clamping the test tube 4, thereby reducing local pressure and avoiding the test tube 4 from being crushed or leaving an indentation.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
