[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model;
[0021] Please refer to Figures 1 to 4, in the present utility model, a reagent rack for laboratory use includes a base plate 1. Equally spaced horizontal grooves 2 are formed in the base plate 1. A bottom plate 3 is slidably connected inside the horizontal grooves 2. A support 4 is fixedly connected to the bottom plate 3. The top of the support 4 is fixedly connected with an upper shelf 5. Tube holes 6 are arranged at equal intervals on both the upper shelf 5 and the bottom plate 3. A positioning mechanism 7 is installed between the right side of the bottom plate 3 and the base plate 1. Suction attachments 8 are installed at the four corners of the base plate 1.
[0022] In the present utility model, with the base plate 1 serving as the support of the device, during use, place the base plate 1 flat on a flat and clean place on the laboratory tabletop. First, rotate the suction attachments 8 at the four corners so that a low-pressure area is formed between the bottom of the suction attachments 8 and the laboratory tabletop, thereby adsorbing and fixing the base plate 1 on the laboratory tabletop, making the device stable in placement and having good support. Then, place the reagent tubes on the upper tube holes 6 in sequence for storage. When taking the reagent tubes in the central area, the positioning mechanism 7 can be pulled open and then the bottom plate 3 can be horizontally pulled to the right to synchronously bring out the upper shelf 5 on the support 4, directly pulling out a row of reagent tubes, which is convenient for operation and effectively avoids bumping. Thus, the device realizes the advantages of being able to independently operate the movement of a row of test tubes, facilitating access and operation, being more flexible in use, and effectively avoiding bumping to protect the reagent tubes, solving the problem in the prior art that due to the dense arrangement of the hole positions, during the experiment, the gaps between more reagent tubes are small, resulting in obstacles during access and easy bumping and damage to the reagent tubes.
[0023] Please refer to Figure 2 , wherein: The positioning mechanism 7 includes a first ear plate 71, a second ear plate 72, a clamping rod 73, and a spring 74. One side of the first ear plate 71 is fixedly connected to the right end of the bottom plate 3. One side of the second ear plate 72 is fixedly installed on the base plate 1. The bottom end of the clamping rod 73 penetrates through the first ear plate 71 and is clamped with the second ear plate 72 downward. The spring 74 is sleeved outside the clamping rod 73. The top end of the spring 74 is fixedly connected to the outside of the clamping rod 73, and the bottom end of the spring 74 is fixedly connected to the first ear plate 71.
[0024] In the present utility model, by pulling up the clamping rod 73 to stretch the spring 74, at this time, the clamping rod 73 slides upward along the first ear plate 71 and separates from the second ear plate 72 at the bottom to release the limit on the bottom plate 3, and then the bottom plate 3 can be horizontally pulled to the right to realize the movement of the entire row of test tubes, facilitating selection and placement.
[0025] Please refer to Figure 2 , wherein: The top end of the clamping rod 73 is fixedly connected with a pulling block 731, and a pulling groove 732 is formed in the pulling block 731.
[0026] In the present utility model, the pulling block 731 facilitates pulling up the clamping rod 73, and the pulling groove 732 facilitates horizontally pulling the bottom plate 3 to move, facilitating operation.
[0027] Please refer toFigure 2 , wherein vertical rods 711 are fixedly connected to both sides of the first ear plate 71, and rollers 712 are rotatably installed at the bottom ends of the vertical rods 711.
[0028] In the present utility model, the rollers 712 at the bottom of the vertical rods 711 roll along the tabletop of the experimental table to achieve movable support for the first ear plate 71, making the movement of the bottom plate 3 more stable.
[0029] Please refer to Figure 1 , Figure 3 and Figure 4 , wherein the adsorbing member 8 includes a screw rod 81, a connecting column 82, a piston block 83, and a conical rubber sleeve 84. The bottom end of the screw rod 81 penetrates into the inside of the substrate 1 and is threadedly connected thereto. The top end of the connecting column 82 is rotatably connected to the screw rod 81. The bottom end of the connecting column 82 is fixedly connected to the piston block 83. The outer side of the conical rubber sleeve 84 is fixedly connected to the inner side of the substrate 1 and extends downward to the bottom of the substrate 1. The outer side of the piston block 83 is slidably connected to the inner side of the upper half of the conical rubber sleeve 84.
[0030] In the present utility model, by rotating the screw rod 81 to move it vertically upward along the substrate 1, the connecting column 82 and the piston block 83 are driven to slide upward along the inner side of the conical rubber sleeve 84. Since the conical rubber sleeve 84 is in contact with the tabletop of the experimental table, as the piston block 83 rises, a negative pressure space is formed between the conical rubber sleeve 84 and the tabletop of the experimental table to achieve adsorption, so as to achieve positioning and stabilization of the substrate 1 and make its use more stable.
[0031] Please refer to Figure 1 , wherein flexible rubber sleeves 61 are fixedly connected to the inner sides of the test tube holes 6.
[0032] In the present utility model, the flexible rubber sleeves 61 provide better support for the reagent tubes on the inner sides of the test tube holes 6, and at the same time reduce bumps and protect the reagent tubes.
[0033] The above is only a preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improvement concept of the present utility model, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present utility model.
