Description

Technical Field

[0001] This utility model relates to the field of weighing technology, specifically to a container structure that facilitates the weighing of solids. Background Technology

[0002] In laboratory fields such as biology, chemistry, food processing, and pharmaceuticals, the accurate weighing of solid powders is a fundamental step in experimental operations, and its accuracy directly affects the reliability of experimental results. Currently, laboratories generally use electronic analytical balances in conjunction with weighing paper for powder weighing.

[0003] However, traditional weighing methods have the following significant drawbacks:

[0004] (1) Powder is easy to spill and scatter: Weighing paper lacks a fixed support structure. During the movement (such as when it is removed from the balance or transferred to the target container), powder or granular solids are easy to spill due to shaking, improper tilting angle or paper deformation. For powders with high fluidity, they may even be scattered due to slight airflow, which will increase the weighing error and may also pollute the experimental environment.

[0005] (2) Low operating efficiency and large residue: Traditional weighing paper has a planar structure, and it is difficult to concentrate the powder after it accumulates. When pouring, the edges of the paper need to be manually pinched to form a funnel shape, which is prone to spillage due to uneven force. The planar structure also causes the powder to adhere to the paper folds, resulting in residue and waste. The residue problem is more prominent, especially for trace or valuable samples.

[0006] (3) Difficulty in fixing weighing paper: In the current operation, the weighing paper is usually laid directly on the balance tray without a special fixing device. When the weighing amount is large, the paper is easy to shift. The folded weighing paper does not fit tightly with the container, and the powder may leak out from the gap between the paper and the container, affecting the weighing accuracy.

[0007] (4) Insufficient stability and inconvenient operation: Traditional weighing methods rely on two hands (such as holding the paper with one hand and pouring with the other), which makes it difficult to control accurately in the small space of the balance, especially when wearing gloves. There are no special grip parts, and the powder is easily spilled due to hand shaking during the movement.

[0008] While some improved weighing containers exist in the prior art (such as weighing bottles with pouring spouts and funnels with clamping structures), they generally suffer from problems such as complex structures, high costs, and difficulty in adapting to different specifications of weighing paper. For example, traditional funnels lack a weighing paper fixing device, requiring manual support of the paper when pouring; some containers with clamping functions use rigid fixing structures, which cannot adapt to changes in paper folding thickness, resulting in insecure fixing or damage to the paper.

[0009] Therefore, how to provide a weighing container that is simple in structure, low in cost, can effectively fix the weighing paper, reduce powder spillage and residue, and is easy to operate with one hand and move stably is a technical problem that urgently needs to be solved in the field of laboratory equipment. Utility Model Content

[0010] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a container structure that facilitates solid weighing. Through the coordinated design of the weighing cup, the handle, and the base, the scattering and spillage of powders and other solids during weighing can be effectively reduced, thereby improving weighing efficiency. It achieves the core functions of preventing spillage, stabilizing and controlling, and efficiently transferring powders during the weighing process.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0013] Optionally, the base adopts a circular and flat structure, the handle is fixedly installed at the center of the base, and multiple stabilizing rods are distributed in a circular array around the axis of the handle.

[0014] Optionally, the upper end of the handle is fixedly connected to the bottom end of the weighing cup, and the weighing cup adopts a four-sided funnel-shaped structure, while the handle adopts a cylindrical structure.

[0015] Optionally, a weighing paper folded at the four corners is embedded in the cavity of the weighing cup, and the outer side of the weighing paper is in contact with the inner wall of the cavity of the weighing cup.

[0016] Optionally, the weighing paper and the weighing cup are fixedly connected by a fixing clip, and the fixing clip is located at the flat upper part of the side wall of the weighing cup and the weighing paper.

[0017] Optionally, the fixing clamp includes a sleeve, the sleeve having an inner core inside, and after the inner core is bent and deformed, the inner side of the sleeve contacts the sidewalls of the weighing cup and the weighing paper respectively.

[0018] Optionally, the stabilizer bar is provided with three bars, and the included angle between two adjacent stabilizer bars is 120 degrees.

[0019] Optionally, a plurality of anti-slip pads are provided on the bottom surface of the base, and the plurality of anti-slip pads are arranged in a circumferential array around the axis of the base.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) In this utility model, the weighing cup is used to hold solid materials, the hand handle is convenient for the experimenter to pick up, and the base frame can provide stable support for the weighing cup and the hand handle. The three are designed together to effectively reduce the scattering and spillage of powder and other solids during weighing, improve weighing efficiency, and the structure is simple, lightweight, low cost, and can be reused for a long time.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. Example 1

[0033] like Figures 1-4 As shown, a container structure for facilitating solid weighing includes a weighing cup 1, a handle 2, a base frame, weighing paper 6, and a fixing clip 7. The weighing cup 1 is used to hold solid materials and is fixedly installed on the upper end of the handle 2 with its open end facing upwards. The base frame is used to stably support the container structure and is fixedly installed on the lower end of the handle 2. The weighing paper 6 is folded at its four corners and fitted into the cavity of the weighing cup 1, with the outer surface of the weighing paper 6 fitting against the inner wall of the cavity of the weighing cup 1. The fixing clip 7 is used to fix the folded weighing paper 6 inside the weighing cup 1.

[0034] As described above, the weighing cup 1 can hold more powder and other solids than the flat weighing paper 6, and prevents them from spilling or scattering; the handle 2 makes it easy for the operator to take out the weighing container with one hand from the analytical balance, preventing solids from spilling during movement; and the stable base ensures the stability of weighing. The coordinated design of the weighing cup 1, handle 2 and base can effectively reduce the scattering and spillage of powder and other solids during weighing, improve weighing efficiency, and the resulting container structure is simple, lightweight, low-cost, and can be reused for a long time.

[0035] Specifically, the base frame includes a base support 3 for supporting the handgrip 2. The base support 3 is perpendicular to the handgrip 2, and multiple stabilizing rods 4 are inclined between them. One end of the stabilizing rod 4 is fixedly connected to the handgrip 2, and the other end is connected to the base support 3 near the edge. The stabilizing rods 4 and the base support 3 form a triangular support structure, which can counteract the inertial shaking when the weighing cup 1 moves and prevent solid powder from spilling during movement.

[0036] The weighing cup 1 features a four-sided funnel-shaped structure, allowing users to easily fold the measuring paper 6 in half to form the inner lining of the cavity. The four-sided funnel shape of the weighing cup 1 also facilitates the accumulation of solids such as powder, and the angular structure guides the powder to fall in a concentrated manner, reducing residue after pouring. The handle 2 has a slender cylindrical structure and is fixedly connected to the funnel tip at the bottom of the weighing cup 1; that is, the upper end of the handle 2 is fixedly connected to the bottom end of the weighing cup 1. The base 3 has a flat, circular structure, with its center fixedly connected to the handle 2. The stabilizing rod 4 is a slender rod used to stabilize the base 3 and the handle 2.

[0037] For example, three stabilizing rods 4 are set here, made of stainless steel, and the angle between the orthographic projections of two adjacent stabilizing rods 4 on the top surface of the base 3 is 120 degrees, that is, multiple stabilizing rods 4 are arranged in a circular array around the axis of the handle 2; if the handle 2 tends to sway, its static force is transmitted to the base 3 along the stabilizing rods 4, which cancels out the reaction force, thereby effectively eliminating the inertial swaying of the weighing cup 1 when it moves.

[0038] To further improve the stability of the weighing container, multiple anti-slip pads 5 can be attached to the bottom surface of the base 3, arranged in a circumferential array around the axis of the base 3. The anti-slip pads 5 can be made of silicone or rubber, which not only increases the friction between the pad and the surface of the balance tray, but also absorbs vibrations during operation, preventing powder from spilling due to vibration.

[0039] In addition, the base 3 can be designed as a ring or disc with outward-expanding edges, with a diameter 1.5-2 times larger than the diameter of the upper opening of the weighing cup 1, forming a "wide-edge base". By expanding the support surface, the pressure per unit area is reduced, and the risk of the base tilting is reduced. Moreover, the wide-edge structure keeps the edge of the base away from the vertical line of the center of gravity. When the container is subjected to external forces (such as inertia during movement), the edge can provide a counter-torque to counteract the shaking.

[0040] like Figure 1 and Figure 5 As shown, the weighing paper 6 and the weighing cup 1 are fixedly connected by a fixing clip 7 with a certain degree of flexibility. The fixing clip 7 is located at the flat upper part of the side wall of the weighing cup 1 and the weighing paper 6. The flat upper part is that is, the non-corner part, which makes it convenient for the fixing clip 7 to fix the two together and ensure that the outer side of the weighing paper 6 fits the inner side of the weighing cup 1 after folding.

[0041] As described above, the fixing clip 7 includes an inner core 701 and a sleeve 702. The inner core 701 is embedded inside the sleeve 702. If there are multiple inner cores, they are arranged in parallel at equal intervals. The inner core 701 can be made of soft and tough materials such as titanium alloy wire and aluminum wire, and the sleeve 702 can follow the deformation of the inner core 701.

[0042] When the operator puts the weighing paper 6 into the weighing cup 1, the operator can choose to fix the weighing paper 6 with the fixing clip 7 or not fix it as needed. When fixing it with the clip 7, simply fold the fixing clip 7 in half so that its clamping opening fits over the side wall of the weighing paper 6 and the weighing cup 1. After the inner core 701 is bent and deformed, the inner side of the clip 702 contacts the side wall of the weighing cup 1 and the weighing paper 6 respectively.

[0043] Taking powder weighing as an example, the usage method of this utility model is explained as follows:

[0044] (1) Take out the weighing paper 6, fold it and put it into the weighing cup 1, and choose to use the fixing clip 7 to fix it or not fix it;

[0045] (2) Place the weighing container into the analytical balance to remove the tare, and then you can start weighing solids such as powders;

[0046] (3) When the weighing is finished, the weighing container can be taken out with one hand by holding the handle 2, which avoids spillage due to unsteady hand or strong solid fluidity when using the weighing paper 6 alone. Example 2

[0047] Based on Embodiment 1, this utility model also proposes another assembly method for the solid weighing container structure, which allows the weighing cup 1, hand handle 2, base 3 and stabilizing rod 4 to be disassembled and replaced, realizing the modular design of the container structure, facilitating production and assembly, and allowing timely replacement when one of the components is damaged.

[0048] Threaded holes are made at the bottom of the weighing cup 1 and the center of the base 3. External threads that cooperate with the internal threads of the threaded holes are provided at both ends of the handle 2, so that the two ends of the handle 2 can be screwed to the weighing cup 1 and the base 3 respectively.

[0049] The base 3 has slots corresponding to the number of stabilizer bars 4, and the multiple slots are arranged in a circular array around the axis of the threaded hole.

[0050] The lower end of the stabilizer bar 4 is fixed with a buckle that corresponds to the slot. The upper end of the stabilizer bar 4 is fixed with a support block. The support block and the buckle are set opposite to each other at the upper and lower ends of the stabilizer bar 4, respectively located on the inner and outer sides. The support block has a groove on the side closer to the handle 2 that matches the outer contour of the handle 2.

[0051] During assembly, first, the weighing cup 1 and the base 3 are fixedly installed at the upper and lower ends of the handgrip 2 by means of threaded connection; then, the buckle at the lower end of the stabilizer 4 is aligned with the embedded slot, and the support block at the upper end is aligned with the handgrip 2. Then, press down to drive the stabilizer 4 to flip, so that the handgrip 2 is inserted into the groove and coaxial with it.

[0052] Working principle:

[0053] The stabilizer bar 4 is firmly locked between the handgrip 2 and the base 3. The stabilizer bar 4 is a two-force bar and is in a mechanical dead point position, so it cannot rotate around the fulcrum, thus achieving self-locking fixation. The base 3 applies an upward preload to the lower end of the stabilizer bar 4 through the slot, which, together with the downward pressure generated by the handgrip 2 being locked into the groove, forms an axial force closed loop, counteracting the tendency of lateral swaying and improving overall stability. The preload of the base is transmitted along the axis, and the stabilizer bar 4 cannot rotate around the slot, thus forming a static balance.

[0054] Among them, the stabilizer bar 4 is distributed in a circumferential array, which can evenly distribute the radial force and avoid bending caused by the eccentric force on the hand grip; while the buckle can adopt a "barb + bevel" design (such as a trapezoidal buckle), which automatically aligns when inserted into the slot, and needs to be pulled upward to unlock when disassembling, to avoid accidental loosening.

[0055] In summary, the container structure for easy solid weighing proposed in this utility model integrates core functions such as paper bonding guidance, powder concentration and spill prevention, and one-handed operation and stable control through the coordinated design of the four-cornered funnel-shaped weighing cup 1, the flexible and adjustable fixing clamp 7, the hand handle 2 and the base frame (base support 3 and stabilizing rod 4 system), achieving a balance of high efficiency and reliability that traditional dispersed structures cannot achieve.
