Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a novel reagent rack. Background Technology

[0002] In biological and chemical experiments, reagent tubes are a very common piece of experimental equipment, and reagent racks are devices used to hold reagent tubes in an orderly manner. Usually, reagent racks have several placement holes arranged in a rectangular array, and reagent tubes are placed in these placement holes.

[0003] For example, Chinese utility model patent (CN220835694U) discloses a reagent rack, which states that: "It has the advantage of making it convenient for the operator to adjust the distance between the placement plate and the base plate according to different sizes of test tubes, thus facilitating the operator's operation."

[0004] Although the above-mentioned reagent rack can adjust the spacing of the placement plates, its basic frame structure is fixed. When placing the reagent rack, it is difficult to adjust the reagent rack according to the shape of the placement space, resulting in low space utilization. Therefore, this application proposes a new type of reagent rack. Utility Model Content

[0005] Therefore, it is necessary to provide a new type of reagent rack to address the above-mentioned technical problems. Through the overall structural design, the base rack, receiving rack, and top rack can be flexibly flipped and adjusted to accommodate different placement spaces and improve space utilization.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A novel reagent rack for laboratory applications;

[0008] The system includes a base frame, a receiving frame, and a top frame. Supports are fixed at the four corners of the base frame's bottom. Two rectangular brackets are fixed at the bottom of the top frame. A first bearing is fixed to the upper end of the base frame near the receiving frame. A first support is rotatably connected to the outer side of the first bearing, and the first support is fixed to the receiving frame. A second bearing is fixed to the bottom end of the receiving frame near the top frame. A second support is rotatably connected to the outer side of the second bearing, and the second support is fixed to the top frame.

A first spring is fixed between the outer side of the other side of the first pull rod and the first support block.

[0010] In a preferred embodiment of the novel reagent rack provided by this utility model, a mounting guide is fixed at the bottom end of the receiving rack away from the top frame. Sliders are symmetrically slidably connected to the inner side of the mounting guide. The sides of the two sliders that are far apart from each other are slidably connected to two rectangular card seats respectively. Two fourth springs are fixed on the sides of the two sliders that are close to each other. The side of each fourth spring that is far away from the slider is fixed to the mounting guide.

[0011] In a preferred embodiment of the novel reagent rack provided by this utility model, a guide post is fixed to the inner side of one side of the base frame, and a screw is rotatably connected to the inner side of the other side of the base frame. The first tube holder is slidably connected to the guide post, and the first tube holder is threadedly connected to the screw.

[0012] In a preferred embodiment of the novel reagent rack provided by this utility model, the upper end of the screw passes through the base frame and is fixed with a first flat gear. The first flat gear is located at the upper end of the base frame. A gear groove is provided inside the upper end of the base frame and outside the first flat gear. A second flat gear is slidably connected to the inner side of the gear groove. The second flat gear meshes with the first flat gear. A third spring is also provided inside the gear groove. The upper end of the third spring is fixed to the second flat gear, and the lower end of the third spring is fixed to the base frame.

[0013] In a preferred embodiment of the novel reagent rack provided by this utility model, a cross-shaped through hole is provided on one side of the second tube holder and outside the receiving frame. A second support block is fixed on one side of the receiving frame and outside the cross-shaped through hole. A second pull rod is slidably connected to the inner side of the second support block.

Detailed Implementation

[0025] As described in the background art, although the above-mentioned reagent rack can adjust the spacing of the placement plates, its basic frame structure is fixed. When placing the reagent rack, it is difficult to adjust the reagent rack according to the shape of the placement space, resulting in low space utilization.

[0026] To solve this technical problem, this utility model provides a novel reagent rack for use in laboratories;

[0027] The system includes a base frame 1, a receiving frame 2, and a top frame 3. Supports 4 are fixed at the four corners of the bottom of the base frame 1. Two rectangular brackets 5 are fixed at the bottom of the top frame 3. A first bearing 6 is fixed at the upper end of the base frame 1 near the receiving frame 2. A first support 7 is rotatably connected to the outer side of the first bearing 6 and is fixed to the receiving frame 2. A second bearing 24 is fixed at the bottom end of the receiving frame 2 near the top frame 3. A second support 25 is rotatably connected to the outer side of the second bearing 24 and is fixed to the top frame 3. A first tube-inserting seat 12 is slidably connected to the inner side of the base frame 1. A second tube-inserting seat 19 is rotatably connected to the inner side of the receiving frame 2. A third tube-inserting seat 29 is fixed to the inner side of the top frame 3.

[0028] The novel reagent rack provided by this utility model, through its overall structural design, allows for flexible flipping and adjustment of the base frame 1, the receiving frame 2, and the top frame 3 in both flat and stacked states. After adjustment, it facilitates the limiting and fixing of the base frame 1 and the receiving frame 2, and the receiving frame 2 and the top frame 3, ensuring overall stability to adapt to different placement space shapes and improve space utilization.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1:

[0032] Please refer to Figure 1-5 A novel reagent rack includes a base frame 1, a receiving frame 2, and a top frame 3. Supports 4 are fixed at the four corners of the bottom of the base frame 1. To facilitate the flexible flipping and adjustment of the base frame 1, the receiving frame 2, and the top frame 3 for flat laying and stacking, a first bearing 6 is fixed at the upper end of the base frame 1 near the receiving frame 2. A first bracket 7 is rotatably connected to the outer side of the first bearing 6. The first bracket 7 is fixed to the receiving frame 2. A second bearing 24 is fixed at the bottom end of the receiving frame 2 near the top frame 3. A second bracket 25 is rotatably connected to the outer side of the second bearing 24. The second bracket 25 is fixed to the top frame 3.

[0033] After the receiving frame 2 is flipped, in order to facilitate the limiting and fixing of the receiving frame 2, two locking blocks 11 are fixed at the upper end of the base frame 1 away from the receiving frame 2, and two first support blocks 8 are fixed at the upper end of the receiving frame 2 away from the base frame 1. A first pull rod 9 is slidably connected to the inner side of each first support block 8. One side of the first pull rod 9 passes through the locking block 11 and is slidably connected to the locking block 11. A first spring 10 is fixed between the outer side of the other side of the first pull rod 9 and the first support block 8.

[0034] After the top frame 3 is flipped, in order to facilitate the limiting and fixing of the top frame 3, two rectangular brackets 5 are fixed at the bottom of the top frame 3. A mounting guide 26 is fixed at the bottom of the support frame 2 away from the top frame 3. Slider 27s are symmetrically slidably connected to the inner side of the mounting guide 26. The two sliders 27s are slidably connected to the two rectangular brackets 5 on the side away from each other. Two fourth springs 28s are fixed on the side of the two sliders 27 that are close to each other. The side of each fourth spring 28 away from the slider 27 is fixed to the mounting guide 26.

[0035] The inner side of the base frame 1 is slidably connected to the first tube seat 12, the inner side of the receiving frame 2 is rotatably connected to the second tube seat 19, and the inner side of the top frame 3 is fixed to the third tube seat 29.

[0036] Example 2:

[0037] The novel reagent rack provided in Example 1 has been further optimized, specifically, as follows: Figure 1-5 As shown, before and after the receiving frame 2 is flipped, the second tube seat 19 is rotated to adapt to the flipping of the receiving frame 2, so that the placement hole in the second tube seat 19 always faces upward. After the second tube seat 19 is rotated, in order to limit and fix the second tube seat 19, a cross through hole 20 is opened on one side of the second tube seat 19 and outside the receiving frame 2. A second support block 21 is fixed on one side of the receiving frame 2 and outside the cross through hole 20. A second pull rod 22 is slidably connected to the inner side of the second support block 21. The lower end of the second pull rod 22 is slidably connected to the cross through hole 20. A second spring 23 is fixed between the outer side of the upper end of the second pull rod 22 and the second support block 21.

[0038] After the reagent tube is placed inside the first tube holder 12, in order to facilitate the adjustment of the height of the first tube holder 12 and thus drive the first tube holder 12 to move upward to press and limit the reagent tube, ensuring that the reagent tube will not fall, a guide post 13 is fixed on the inner side of one side of the base frame 1, and a screw 14 is rotatably connected to the inner side of the other side of the base frame 1. The first tube holder 12 is slidably connected to the guide post 13, and the first tube holder 12 is threadedly connected to the screw 14.

[0039] After the height of the first tube holder 12 is adjusted, in order to limit the rotation of the screw 14 and thus fix the height of the first tube holder 12, the upper end of the screw 14 passes through the base frame 1 and is fixed with a first spur gear 15. The first spur gear 15 is located at the upper end of the base frame 1. A gear groove 16 is provided inside the upper end of the base frame 1 and outside the first spur gear 15. A second spur gear 17 is slidably connected inside the gear groove 16. The second spur gear 17 meshes with the first spur gear 15. A third spring 18 is also provided inside the gear groove 16. The upper end of the third spring 18 is fixed to the second spur gear 17, and the lower end of the third spring 18 is fixed to the base frame 1.

[0040] The usage process of the novel reagent rack provided by this utility model is as follows: When it is necessary to adjust the reagent rack to a stacked state to adapt to the shape of the space, such as... Figure 2 As shown, the receiving frame 2 is first rotated around the first bearing 6 as the axis. During the rotation, the two first pull rods 9 are pulled. After the rotation is completed, the two first pull rods 9 are released. The elasticity of the first spring 10 is used to drive the two first pull rods 9 to return to their original position and slide into the inner side of the two locking blocks 11, thus completing the limiting and fixing between the base frame 1 and the receiving frame 2.

[0041] Then, the top frame 3 is flipped with the second shaft seat 24 as the axis. During the flipping, the two sliders 27 are pulled so that the two sliders 27 are close to each other and squeeze the fourth spring 28. After the flipping is completed, the two sliders 27 are released. The elasticity of the fourth spring 28 is used to drive the two sliders 27 to return to their original position and slide into the inside of the two rectangular card seats 5, thus completing the limiting and fixing between the receiving frame 2 and the top frame 3.

[0042] At this time, pull the second pull rod 22 to slide it out of the cross through hole 20, so as to facilitate the rotation of the second tube seat 19 by 180 degrees, so that the placement hole in the second tube seat 19 always faces upward. After the second tube seat 19 has been rotated, release the second pull rod 22 and use the elasticity of the second spring 23 to drive the second pull rod 22 to reset, so that the second pull rod 22 slides back into the cross through hole 20, thereby limiting and fixing the second tube seat 19.

[0043] After the reagent tube is placed into the first tube holder 12, press the second flat gear 17 to make it slide into the gear groove 16, thereby disengaging the second flat gear 17 from the first flat gear 15, making it easier to rotate the screw 14, which in turn drives the first tube holder 12 to be raised and lowered by the guide post 13, making it easier to move the first tube holder 12 upward, so that the upper end of the reagent tube placed in the first tube holder 12 is pressed against the top of the inner side of the base frame 1 to limit it, ensuring that the reagent tube will not fall off. After the first tube holder 12 is adjusted and the teeth of the second flat gear 17 and the first flat gear 15 are aligned, release the second flat gear 17 and use the elasticity of the third spring 18 to drive the second flat gear 17 to reset, so that the second flat gear 17 re-engages with the first flat gear 15, thereby completing the fixation of the first tube holder 12.
