Description

Technical Field

[0001] The utility model relates to a bag hanging bracket, which is used for hanging reagent bags and can fix a liquid outlet pipeline. Background Art

[0002] During experiments in the fields of biology, chemistry, and medicine, when taking bagged liquid reagents, one hand is usually used to hold the bag, turn it upside down, and squeeze out the liquid, while the other hand holds the liquid outlet pipe. When holding the bag with one hand, the hand is prone to shaking due to continuous force, which can cause the liquid outlet pipe to become unstable, causing liquid to leak out and contaminating the reagents and the desktop. The operator's hands need to control the bag and the liquid outlet pipe separately, resulting in the inability to timely control the switch of the liquid outlet pipe and the liquid flow rate. Currently, most height-adjustable brackets are placed on the ground, with a height of more than 1m. Brackets of this height are not suitable for use on the desktop.

[0003] When transferring liquid reagents, the reagent bag and collection device are connected via a liquid outlet line. During this process, the collection device must be weighed to determine the weight of the transferred liquid reagent. Traditionally, the collection device is placed on a scale for weighing, leaving the liquid outlet line hanging naturally. The position, angle, and length of the liquid outlet line hanging on the scale vary between weighings, leading to errors in the weighing results. When an experiment involves multiple weighings, the cumulative error is significant, and the smaller the target liquid weight, the greater the relative error. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the present invention provides a bag-hanging stand. When transferring liquid reagents, the reagent bag and collection device are connected via a liquid outlet pipe. This stand secures both the reagent bag and the liquid outlet pipe, freeing both hands and facilitating experimental operations. Furthermore, when weighing transferred liquids, the stand secures the position, angle, and length of the liquid outlet pipe on the balance, minimizing the error associated with each weighing. This stand can be placed on a laboratory bench or in a biological safety cabinet.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A bag hanging bracket includes: a base, a first bracket fixed to the base, and a second bracket; the first bracket has a hook at the top; the second bracket includes: a main support rod, a serpentine hose connected to the main support rod, and a liquid outlet pipeline clamping device arranged at the end of the serpentine hose.

[0007] In this technical solution, the base is used to fix the first bracket and the second bracket. The base has a certain weight to keep it stable and prevent it from tilting. The hook at the top of the first bracket is used to hang the reagent bag. The second bracket is used to fix the liquid outlet pipeline. The main support rod is fixed on the base to play a supporting role. The serpentine hose is preferably a metal hose with good toughness. It can be adjusted and fixed 360° at will, so that the liquid outlet of the liquid outlet pipeline can be moved within a certain range and easily adjusted to the optimal position and angle. The liquid outlet pipeline clamping device is clamped at an appropriate position at the end of the liquid outlet pipeline to fix the liquid outlet pipeline.

[0008] Preferably, the first bracket includes a first column, a second column, a bolt and a nut; the first column is a hollow cylindrical structure, the lower end of which is fixed to the base, and a first slide groove and a second slide groove are provided on the side wall, and the first slide groove and the second slide groove are symmetrically distributed relative to the central axis; the second column is sleeved inside the hollow cavity of the first column, and the second column has a hook at the top and a through hole at the bottom; the bolt penetrates the first slide groove, the through hole and the second slide groove in sequence and is fixed with a nut.

[0009] In this technical solution, the height of the first bracket is adjustable. The second column can move up and down within the hollow cavity of the first column. When the second column is moved up and down to the desired height, a bolt is sequentially inserted through the first slot on the side wall of the first column, the through hole of the second column, and the second slot on the side wall of the first column. The head of the bolt is stuck outside the first slot, and the nut is stuck outside the second slot. When the nut is tightened, the nut and the head of the bolt are simultaneously pressed from the outside of the first column to the inside of the second column, thereby fixing the positions of the first and second columns.

[0010] Preferably, the widths of the first and second sliding grooves and the diameter of the through hole all match the diameter of the bolt.

[0011] In this technical solution, the widths of the first and second chute grooves and the diameter of the through hole allow the bolt to just pass through, and the side walls of the bolt are in close contact with the side walls of the first chute groove, the through hole, and the second chute groove.

[0012] Preferably, a rubber gasket is provided at the contact points between the head of the bolt, the nut and the outer side wall of the first column.

[0013] In this technical solution, the rubber gasket can increase the friction force at the contact point between the bolt head, the nut and the outer side wall of the first column, so that the fixation of the first column and the second column is more stable and firm.

[0014] Preferably, the number of the hooks is 1-5.

[0015] In this technical solution, according to experimental requirements, the first bracket can simultaneously hang 1, 2, 3, 4 or 5 reagent bags.

[0016] Preferably, the liquid outlet pipeline clamping device is a C-shaped clamp, and the inner diameter of the C-shaped clamp matches the outer diameter of the liquid outlet pipeline.

[0017] In this technical solution, the C-shaped clamp is in the shape of the letter "C", and the groove inside the C-shaped clamp is used to accommodate the liquid outlet pipeline. The inner diameter of the C-shaped clamp matches the outer diameter of the liquid outlet pipeline, so that the inner wall of the C-shaped clamp fits with the outer wall of the liquid outlet pipeline, preventing the liquid outlet pipeline from falling off from the opening of the C-shaped clamp. When in use, the liquid outlet pipeline is compressed and pushed hard from the opening of the C-shaped clamp into the groove, and it can enter the groove and be fixed; during the experiment, the liquid outlet pipeline returns to its normal state to facilitate liquid flow, and the liquid outlet pipeline will not fall off from the opening of the C-shaped clamp; after the experiment is completed, the liquid outlet pipeline is compressed again and pulled out from the opening of the C-shaped clamp groove, which is easy to operate.

[0018] Preferably, the distance between the two free ends of the C-shaped clamp opening is 1 / 4-3 / 4 of the inner diameter of the C-shaped clamp.

[0019] In this technical solution, the C-shaped clamp opening allows the liquid outlet pipeline to pass through in a radially compressed state, and prevents the liquid outlet pipeline in the groove from falling off from the C-shaped clamp opening.

[0020] Preferably, the inner side wall of the C-shaped clip is provided with anti-slip grooves.

[0021] In this technical solution, the anti-slip grooves can increase the friction between the contact surface between the inner side wall of the C-shaped clamp and the liquid outlet pipeline, preventing the liquid outlet pipeline from moving relative to each other, and ensuring that the liquid outlet pipeline is fixed more firmly.

[0022] Preferably, the two free ends of the C-shaped clip opening can be slightly deformed and can be restored to a closed state.

[0023] In this technical solution, the C-shaped clamp is made of a semi-rigid material, such as stainless steel, metal, or plastic, so the two free ends of the C-shaped clamp opening can be fine-tuned outward according to the outer diameter of the liquid outlet pipe. Normally, the two free ends of the C-shaped clamp opening are closed. To insert or remove the liquid outlet pipe, the two free ends can be manually pried apart to widen the opening and facilitate the passage of the liquid outlet pipe. After the liquid outlet pipe has passed, the hands are released, and the two free ends return to the closed state, preventing the liquid outlet pipe from falling out of the opening.

[0024] Preferably, the first support can be adjusted in height between 20 cm and 1 m, between 30 cm and 80 cm, between 30 cm and 60 cm, or between 30 cm and 50 cm. The height of the first column can be about 20 cm, about 30 cm, about 40 cm, about 50 cm, about 60 cm, about 70 cm, about 80 cm, about 90 cm, or about 1 m; the height of the second column can be about 20 cm, about 30 cm, about 40 cm, about 50 cm, about 60 cm, about 70 cm, about 80 cm, about 90 cm, or about 1 m.

[0025] Preferably, the height of the first column is about 30 cm, about 40 cm, or about 50 cm; the height of the second column is about 30 cm, about 40 cm, or about 50 cm.

[0026] Preferably, the height of the first column is the same as the height of the second column.

[0028] (1) Hang the reagent bag upside down on the hook and rely on gravity to transfer the liquid, freeing your hands.

[0029] (2) Fix the liquid outlet pipeline to prevent liquid splashing and contamination due to unstable hands, saving manpower.

[0030] (3) Fix the position, angle and length of the liquid outlet pipe when it is placed vertically on the balance to reduce weighing errors.

More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific implementation method.

[0039] For example, a description later in the specification of a first feature being formed above or on a second feature may include an embodiment in which the first and second features are directly connected, or an embodiment in which an additional feature is formed between the first and second features, thereby eliminating the need for a direct connection between the first and second features. Furthermore, when a first element is described as being connected to or coupled to a second element, the description includes embodiments in which the first and second elements are directly connected or coupled to each other, as well as embodiments in which the first and second elements are indirectly connected or coupled to each other using one or more other intervening elements.
