Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of glassware drying equipment, specifically a laboratory drain rack with a receiving trough. Background Technology
[0002] Laboratories have a wide variety of glassware, with petri dishes and test tubes being essential items in most labs. These items need to be washed and drained after use. Due to budget constraints, some small and medium-sized laboratories typically wash them manually. To prevent contamination, all kinds of glassware used in laboratories are disinfected and washed after each use. Currently, washed glassware is dried using a draining rack, where test tubes or graduated cylinders are placed upside down on the rack to air dry. However, laboratories need to place other glassware, such as petri dishes, that are difficult to secure, in addition to test tubes and graduated cylinders. Test tubes also need to be placed on draining racks after washing. Currently, most commercially available test tube draining racks for testing laboratories are relatively small and unsuitable for draining large quantities of bottles. Furthermore, the drain tubes are often thin, which can easily lead to algae growth and blockage over time.
[0003] This case arose in order to resolve the aforementioned issues. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a laboratory drain rack with a receiving trough, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a laboratory drain rack with receiving trough, comprising a drain rack body, a storage layer, and storage columns. The drain rack body is provided with multiple storage layers, and multiple storage columns are provided at equal intervals on the storage layers. Each storage column is provided with a water passage trough. A displacement structure is provided on the rear side of the storage layer. The storage layer is slidably connected to the drain rack body.
[0006] Preferably, the displacement structure includes a connecting rod, a limiting groove, a moving block, a stop rod, and a spring. A fixing block is provided on the rear side of the main body of the drain rack, and a slide rail is fixedly connected to the fixing block. The moving block is slidably connected to the slide rail.
[0007] Preferably, the movable block is provided with a limiting groove, and a connecting rod is slidably connected to the limiting groove. One end of the connecting rod is fixedly connected to the fixed block, and one end of a spring is fixedly connected to the rear side of the movable block. The other end of the spring is fixedly connected to the front side of the fixed block.
[0008] Preferably, a stop rod is fixedly connected to the front side of the movable block, the end of the stop rod protrudes through the slide rail, a vertical plate is fixedly connected to the bottom surface of the slide rail, a fixed plate is connected to the bottom surface of the movable block, and a sliding groove is provided on the fixed plate.
[0009] Preferably, a cylindrical pin is slidably connected in the sliding groove, the cylindrical pin is connected to a lever, and the end of the lever is rotatably connected to the vertical plate.

[0011] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model provides a laboratory drain rack with a receiving trough. The multi-layer drawer design can increase the capacity of the drain rack. The bottom is equipped with a receiving trough with a valve to receive water and discharge it periodically, which is convenient and time-saving. In addition, a fixing structure is provided on the back side of the storage layer. By pushing the storage layer backward, the storage layer can be fixed and the support rod can be used to push the storage layer out, which can be easily stored and placed, and prevent glassware from being exposed to the outside and thus being contaminated.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0018] like Figure 1-4As shown: A laboratory drain rack with a receiving trough includes a main body 1, storage layers 2, and storage columns 3. The main body 1 has multiple storage layers 2, and multiple storage columns 3 are evenly spaced on the storage layers 2. Each storage column 3 has a water channel 4 at its location. The rear side of the storage layer 2 has a shifting structure. The storage layer 2 is slidably connected to the main body 1. When glassware is hung upside down on the storage column 3, the water inside will drip down and flow down the water channel 4. The bottom of the main body 1 is equipped with a receiving trough with a valve to collect water and discharge it periodically, which is convenient and time-saving.
[0019] The displacement structure includes a connecting rod 6, a limiting groove 7, a moving block 8, a stop rod 9, and a spring 10. A fixing block 5 is provided on the rear side of the drain rack body 1, and a slide rail is fixedly connected to the fixing block 5. The moving block 8 is slidably connected to the slide rail. In the normal state, the storage layer 2 is located inside the drain rack body 1, and the lever 16 is engaged with the locking block 11. When the storage layer 2 is pushed inward, the bottom of the storage layer 2 abuts against the stop rod 9 and pushes it inward. The moving block 8 is pushed inward as a whole, compressing the spring 10. The connecting rod 6 moves along the limiting groove 7 to its end as the moving block 8 moves. At this point, the moving block 8 is pushed forward, thereby driving the stop rod 9 forward. As the storage layer 2 is pushed forward, the sliding groove 13 moves forward. Since the sliding groove 13 itself is inclined with an arc, as the sliding groove 13 moves forward, the cylindrical pin 14 rotates, causing the lever 16 to rotate downward, so that the lever 16 is no longer stuck on the locking block 11. The storage layer 2 is popped out as a whole and can be pulled out. When fixing the storage layer 2, it is pushed inward, pushing the abutment 9 and the moving block 8 inward, so that the connecting rod 6 returns to its original position along the limiting groove 7. At this time, the sliding groove 13 moves backward, and the lever 16 rotates upward with the cylindrical pin 14 as the center to lock the locking block 11, thereby fixing and limiting the storage layer 2.
[0020] The movable block 8 is provided with a limiting groove 7, and a connecting rod 6 is slidably connected to the limiting groove 7. A buffer recess is provided at both ends of the limiting groove 7 to hold the connecting rod 6. One end of the connecting rod 6 is fixedly connected to the fixed block 5. One end of the spring 10 is fixedly connected to the rear side of the movable block 8, and the other end of the spring 10 is fixedly connected to the front side of the fixed block 5.
[0021] A stop rod 9 is fixedly connected to the front side of the movable block 8. The end of the stop rod 9 extends out of the slide rail. A vertical plate 15 is fixedly connected to the bottom surface of the slide rail. The vertical plate plays a fixed limiting role for the lever 16. Therefore, when the sliding groove 13 moves, the cylindrical pin 14 drives the lever 14 to rotate up and down while the lever 16 itself remains in the same position. A fixed plate 12 is connected to the bottom surface of the movable block 8. A sliding groove 13 is opened on the fixed plate 12. A cylindrical pin 14 is slidably connected in the sliding groove 13. The cylindrical pin 14 is connected to the lever 16. The end of the lever 16 is rotatably connected to the vertical plate 15.
[0022] A locking block 11 is fixedly connected to the bottom surface of the storage layer 2, and the locking block 11 has a downward protrusion near the position of the moving block 8.
[0023] The above-described embodiments are for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
