Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reagent racks, in particular to a reagent rack for laboratories. Background Art
[0002] Reagent racks are generally installed on the countertops of laboratory tables, laboratory cabinets, and central laboratory tables. Their main function is to place glassware, test tubes, and medicines to facilitate experimental operations. They are generally divided into all-wood reagent racks and steel-wood reagent racks. The main body of the reagent rack is made of 1.0mm aluminum alloy profiles that are cut, positioned, and punched before forming.
[0003] The Chinese patent CN219540358U was retrieved and disclosed a laboratory reagent rack. Through the coordinated use of a motor, a screw rod, a slide rod, a first adjustment block, a second adjustment block, a first placement plate and a second placement plate, the use height can be flexibly adjusted according to the use situation, thereby reducing the use limitations. Through the use of a clamping groove and a clamping block, the height between the first placement plate and the second placement plate can be adjusted. The Chinese patent CN218854365U was retrieved and disclosed a laboratory functional combination reagent rack. The rotating block rotates the rotating column to drive the gear to rotate, thereby driving the two moving rods to move toward each other. The positioning pin is moved to separate from the fixing plate, and the position of the support plate and the distance between the plurality of support plates can be adjusted according to actual use requirements, so that laboratory items of different heights can be placed. The above-mentioned patent documents retrieved all adjust the distance or height to store laboratory items of different sizes to increase the flexibility of placement, and the spacing between the placement holes left between the manufactured reagent racks is small, so that the spacing between the test tubes is also very small, resulting in the fingers being hindered by other test tubes when taking the test tubes, and the test tubes themselves are slippery, which causes inconvenience in taking the test tubes. In view of this, a laboratory reagent rack is proposed. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a laboratory reagent rack, which has the advantage of being convenient for taking test tubes and solves the problem of being inconvenient for taking test tubes.
[0005] In order to achieve the above-mentioned purpose of facilitating the taking of test tubes, the utility model provides the following technical solution: a laboratory reagent rack, comprising a casing and a test tube, the casing being provided with a cover plate, a tube being fixedly mounted on the top of the cover plate, the test tube being located in the tube tube, and the casing and the cover plate being provided with ejection components for facilitating the taking out of the test tube.
[0006] Furthermore, the ejection assembly includes a movable shaft, a cam, an ejection rod and an ejection block, the movable shaft is rotatably connected to the housing, the cam is fixedly installed on the outer surface of the movable shaft, the ejection rod is slidably connected in the cover plate, the ejection rod is in contact with the outer surfaces of the movable shaft and the cam, and the ejection block is fixedly installed on the top of the ejection rod.
[0007] Furthermore, the cams are staggeredly distributed on the outer surface of the movable shaft, the cams are distributed at three positions on the outer surface of the movable shaft, and the top view shape of the tube is a square shape.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-3 A laboratory reagent rack includes a casing 1 and a test tube 2. The casing 1 is provided with a cover plate 3, which is fixed to the top of the casing 1 with mounting screws. A tube 4 is fixedly installed on the top of the cover plate 3. The top view of the tube 4 is a square shape. The test tube 2 is located in the tube 4. The outer surface of the test tube 2 is provided with a reagent label 8, and the content of the label can be checked to know which reagent is stored.
[0020] See also Figure 1-4 The casing 1 and the cover plate 3 are provided with an ejection assembly 5 for taking out the test tube 2 for use. The ejection assembly 5 includes a movable shaft 51, a cam 52, an ejection rod 53 and an ejection block 54. The movable shaft 51 is rotatably connected to the casing 1. A handle 6 is fixedly installed at one end of the movable shaft 51. A positioning screw 7 threadedly connected to the outer surface of the casing 1 is inserted into the handle 6. The positioning screw 7 can be used to fix the handle 6, and then the movable shaft 51 is positioned to avoid the test tube 2 from continuing to rotate when the test tube 2 is not in use as much as possible, thereby playing a limiting role. The cam 52 is fixedly installed on the outer surface of the movable shaft 51. The rotation of the movable shaft 51 can drive the cam 52 to rotate accordingly. The cams 52 are staggered on the outer surface of the movable shaft 51. The cams 52 are distributed on three directions of the outer surface of the movable shaft 51, so that the test tube 2 can be staggered up and down, thereby facilitating the taking out of the test tube 2.
[0021] The ejector rod 53 is slidably connected in the cover plate 3, and the ejector rod 53 can move up and down in the cover plate 3. The lower surface of the ejector rod 53 is arc-shaped. The ejector rod 53 contacts the outer surface of the movable shaft 51 and the cam 52, so that the ejector rod 53 can be driven by the movable shaft 51 and the cam 52 to move upward, and can also fall due to gravity. The ejector block 54 is fixedly installed on the top of the ejector rod 53, and the test tube 2 is combined on the top of the ejector block 54. The test tube 2 is combined on the top of the ejector block 54 in a plug-in manner. When the ejector block 54 moves upward, the test tube 2 can be pushed out. The ejector block 54 is in the shape of a quadrangular prism. The ejector block 54 is slidably connected to the inner side wall of the tube 4, so that the ejector block 54 can only move up and down, which plays a limiting role. The ejector block 54 contacts the cover plate 3. When it contacts the cover plate 3, the ejector block 54 no longer moves downward.
[0022] When using this embodiment, first select the required test tube 2, then find the movable shaft 51 of the corresponding column, unscrew the positioning screw 7, turn the corresponding handle 6, and the movable shaft 51 and the cam 52 will rotate accordingly. The cam 52 gradually pushes the ejection rod 53 and the ejection block 54 upwards, thereby pushing the test tube 2 out. At this time, the required test tube 2 can be easily taken out.
[0023] The beneficial effects of the above embodiments are:
[0024] The laboratory reagent rack is provided with an ejection assembly 5. After the ejection assembly 5 is used, the movable shaft 51 and the cam 52 can be rotated. After the cam 52 contacts the ejection rod 53, the ejection block 54 can be pushed to move upward, and the test tube 2 on the ejection block 54 is gradually ejected. After the height of the test tube 2 to be taken is higher than the adjacent test tube 2, the test tube 2 can be easily taken out, ensuring that the test tube 2 is convenient and quick to take. By providing the handle 6 and the positioning screw 7, the rotation position of the movable shaft 51 is conveniently fixed, and the test tube 2 is prevented from continuing to rotate when the test tube 2 is not in use. This plays a limiting role and solves the problem of inconvenience in taking the test tube.
