Description

Technical Field

[0001] The utility model relates to the technical field of reagent storage instruments, in particular to a reagent rack. Background Art

[0002] Traditional reagent racks are often designed with a planar layout and placed in a refrigerator. Although this design is simple, it has obvious defects in actual use. When there are many reagents on the rack, the reagents in the back row are easily blocked by those in the front row, and the remarks on the label paper in the back row cannot be seen, resulting in the user having to frequently move or remove the front-row reagents to find the reagents in the back row. This undoubtedly increases the working time and difficulty and reduces work efficiency. Secondly, the laboratory space is limited. If the reagent rack occupies too much space during non-use or transportation, it will pose challenges to the space management of the laboratory. Especially when it is necessary to move or store the rack, if its volume is large and it cannot be folded, it will bring a lot of inconvenience to the daily work of the laboratory. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems existing in the prior art, and to propose a reagent rack that can store a large number of reagents, facilitate users to quickly find the required reagents, and can be folded to reduce the occupied space.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A reagent rack includes a base and four racks arranged in the base. The four racks are evenly arranged and are provided with placement holes distributed at intervals along their lengths. The front side or top surface of each rack can be used to bond labels corresponding to the positions of the placement holes.

[0006] The frontmost rack is fixedly connected to the inner wall of the base. An adjusting component is arranged in the base, and the adjusting component is connected to the three rear racks. The three rear racks have a deployed state and a stored state, and the adjusting component controls the three rear racks to switch between the deployed state and the stored state.

[0007] Preferably, the adjusting component includes two screws symmetrically distributed with respect to the racks and rotatably connected to the base. Three moving blocks are threadedly connected to the outer wall of each screw from front to back. A connecting pin is fixedly connected to one side of each moving block facing the rack, and a fixing pin is fixedly connected to both sides of each rack. A connecting rod is hingedly installed between two adjacent connecting pins and fixing pins.

[0008] Preferably, an adjustment knob rotatably connected thereto is inserted through the front surface of the base. One end of the adjustment knob located inside the base is fixedly sleeved with a driving sprocket. Driven sprockets are fixedly sleeved on the outer walls of the two screws. A chain is arranged to drive between the driving sprocket and the two driven sprockets.

[0009] Preferably, chutes are formed on the back surfaces of the three front-side placement racks, and sliders are fixedly connected to the front sides of the three rear-side placement racks. The sliders are located in the chutes and slide up and down along the chutes.

[0010] Preferably, the slider is a "convex"-shaped member, and the shape of the chute is adapted to that of the slider.

[0011] Preferably, the lengths of the three connecting rods on the same side gradually increase from front to back, and the three connecting rods on the same side are staggered from left to right.

[0012] Preferably, a notch is formed on the front surface of the frontmost placement rack. The distance of the notch from front to back is less than the minimum distance between the front side of the placement rack and the placement hole. The chain can pass through the notch.

[0013] Preferably, a lid is further provided, and the lid has two heights, one adapted to the unfolded state of the placement rack and the other adapted to the stored state of the placement rack.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0015] 1. In the present utility model, in the use state, it presents a trapezoidal cross-sectional structure. The four placement racks are arranged from front to back, and the rear placement rack is higher than the front row. The stepped design ensures that the label paper on the rear placement rack will not be blocked by the front row. Without taking out the reagents in the front row, the label paper in the rear row can be directly recognized, so that the required reagent can be easily taken out. Compared with the traditional flat setting structure, it not only saves the user's time, but also improves the work efficiency, and greatly improves the use convenience.

[0016] 2. In the present utility model, by rotating the adjustment knob, the driving sprocket synchronously drives the two screws to rotate through the chain. The screw drives the moving block to move through the thread transmission, and pulls the corresponding placement rack through the connecting pin, the connecting rod and the fixing pin, so that it moves vertically downward and enters the base, so that it has a folding function, significantly reduces the occupied space, and makes it easier to place or carry.

[0017] 3. In the present utility model, the folding and unfolding operations are very simple. Just rotate the adjustment knob forward or backward, and the placement rack can be switched between the unfolded state and the stored state, which can meet the requirements of different occasions and improve its use flexibility.

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] As Figures 1-5 shown, the present utility model provides a reagent rack, including a base 1 and four racks 2 arranged in the base 1. The four racks 2 are evenly arranged and are provided with placement holes 21 distributed at intervals along their lengths. The front side or top surface of each rack 2 can be used for bonding labels corresponding to the positions of the placement holes 21;

[0027] The frontmost rack 2 is fixedly connected to the inner wall of the base 1. An adjustment component 3 is arranged in the base 1. The adjustment component 3 is connected to the three rear racks 2. The three rear racks 2 have a deployed state and a storage state. The adjustment component 3 controls the three rear racks 2 to switch between the deployed state and the storage state.

[0028] In this embodiment, the adjustment component 3 includes two screws 31 symmetrically distributed with the placement rack 2 and rotatably connected to the base 1. Three moving blocks 32 are threadedly connected from front to back on the outer wall of each screw 31. Each moving block 32 is fixedly connected with a connecting pin 33 on the side facing the placement rack 2. Each of the two sides of the placement rack 2 is fixedly connected with a fixing pin 34. A connecting rod 35 is hingedly installed between two adjacent connecting pins 33 and fixing pins 34.

[0029] In this embodiment, an adjustment knob 36 rotatably connected to the base 1 is inserted on the front side of the base 1, and a driving sprocket 37 is fixedly sleeved on one end of the adjustment knob 36 located inside the base 1. A driven sprocket 38 is fixedly sleeved on the outer walls of the two screw rods 31, and a chain 39 is provided for transmission between the driving sprocket 37 and the two driven sprockets 38.

[0030] In this embodiment, the back sides of the three placement racks 2 on the front side are all provided with sliding grooves 22, and the front sides of the three placement racks 2 on the rear side are all fixedly connected with sliders 23, and the sliders 23 are located in the sliding grooves 22 and slide up and down along the sliding grooves 22. The sliders 23 are "convex" shaped components, and the shapes of the sliding grooves 22 and the sliders 23 are adapted to each other. The sliders 23 slide along the sliding grooves 22 to limit the corresponding placement racks 2, so that when the connecting rod 35 pulls the placement rack 2, the placement rack 2 moves vertically up and down.

[0031] In this embodiment, the three connecting rods 35 on the same side gradually increase in length from front to back, and the three connecting rods 35 on the same side are staggered from left to right. When the device is turned to the storage state, there will be no interference between the three adjacent connecting rods 35.

[0032] In this embodiment, a notch 24 is provided on the front of the placement rack 2 at the frontmost side, and the distance from the front to the back of the notch 24 is smaller than the minimum distance between the front side of the placement rack 2 and the placement hole 21. The chain 39 can pass through the notch 24, so that the chain 39 will not affect the reagent placed in the placement hole 21 when working.

[0033] In this embodiment, a cover 4 is further provided, and the cover 4 has two heights. The high cover 4 is adapted to the unfolded state of the placement rack 2, and the low cover 4 is adapted to the storage state of the placement rack 2. When the three placement racks 2 in the rear row are in the storage state, the low cover 4 can be placed on the base and cover the placement rack 3. When storing reagents, multiple groups can be stacked.

[0034] How to use and working principle of this device:

[0035] When in use, the device is in an unfolded state and has an overall trapezoidal cross-section structure. The four placement racks 2 are arranged from front to back in the upper right front, and the rear row is higher than the front row. The label paper on the rear placement rack 2 will not be blocked by the front row, so that the label paper on the rear row can be directly identified without taking out the reagents in the front row, facilitating the extraction of the required reagents. Compared with the existing structure with a flat setting, the convenience of use is greatly improved;

[0036] When the device is not in use or during transportation, its unfolded state occupies a large space, causing inconvenience for shelving or transportation. At this time, the active sprocket 37 can be rotated by rotating the adjustment knob 36. The active sprocket 37 drives the rotation of the two screw rods 31 synchronously through the chain 39. The screw rods 31 drive the movement of the moving blocks 32 through screw transmission, and pull the corresponding placement racks 2 through the connecting pins 33, connecting rods 35 and fixing pins 34. The placement racks 2 move vertically downward and enter the base 1 through the cooperation of the sliders 23 and the chutes 22, realizing folding and reducing the occupied space, so as to facilitate shelving or transportation. When it is necessary to convert to the unfolded state, just reverse the adjustment knob 36.

[0037] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
