Description

Technical Field

[0001] This utility model belongs to the technical field of laboratory weighing auxiliary tools, specifically relating to a funnel-shaped graduated weighing spoon. Background Technology

[0002] In routine laboratory operations, weighing spoons are a core auxiliary tool for measuring solid powders or granular samples, widely used in key steps such as sample pretreatment and experimental reaction preparation. Currently, most traditional weighing spoons used in laboratories are flat-bottomed spoons without graduation markings, which presents several shortcomings in practical operation: Traditional weighing spoons are "blind weighing" tools. Operators cannot directly judge the sample quantity by looking at the spoon. They need to repeatedly transfer the sample to the weighing pan of the balance for adjustment. This is especially time-consuming and labor-intensive in scenarios where a fixed amount of the same sample needs to be weighed repeatedly, such as batch testing experiments, which seriously reduces work efficiency.

[0003] Spillage is prone to occur during sample transfer. After weighing a sample with a traditional weighing spoon, the spoon must be inverted to pour the sample into a crucible or other container. During this inversion process, the sample is prone to spilling from the spoon opening, which not only leads to sample loss and requires reweighing and rework, but may also contaminate the lab bench or other samples, affecting the accuracy of the experimental results. If the sample is a toxic or corrosive substance, spillage can also pose a safety hazard.

[0004] After sample transfer, an additional leveling process is required. After the sample is poured into the crucible, it needs to be leveled using tools such as a glass rod to ensure the uniformity of subsequent experiments. This adds an extra step and further prolongs the experimental preparation time.

[0005] Therefore, developing a weighing spoon that can achieve accurate measurement, spill-free transfer, and simplified operation procedures has become a key requirement for solving the pain points of existing technologies and improving laboratory work efficiency. Utility Model Content

[0006] To address the problems of inaccurate measurement, spillage during sample transfer, and the need for additional leveling after sample transfer, traditional weighing spoons are designed to provide a funnel-shaped graduated weighing spoon. This spoon can replace traditional weighing spoons, enabling precise sample measurement, spill-free transfer, and rapid leveling, thereby improving the efficiency and accuracy of laboratory weighing operations.

[0007] The technical solution adopted by this utility model for a funnel-shaped graduated weighing spoon is as follows: A funnel-shaped graduated weighing spoon includes a spoon body and a spoon handle fixed to the outer wall of the spoon body. The spoon body includes a cylindrical storage part with graduated lines on its side wall along its height direction. A frustum-shaped discharge part is connected below the storage part. The large-diameter end of the discharge part is connected to the bottom of the storage part. A discharge plate is slidably provided at the connection between the discharge part and the storage part, which can close the bottom of the storage part and can be pulled along the spoon handle.

[0008] A further improvement of this utility model is that a pull-out opening adapted to the unloading plate is provided at the connection between the material discharge section and the material storage section, and the unloading plate is slidably disposed in the pull-out opening.

[0009] A further improvement of this utility model is that: the spoon handle is slidably connected to a slider that can move along the spoon handle, and one side of the unloading plate extends out of the spoon body and is connected to the slider, while the surface of the slider is provided with anti-slip texture.

[0010] A further improvement of this utility model is that sealing strips for sealing the pull-out opening are provided on the upper and lower sides of the unloading plate at positions corresponding to the pull-out opening.

[0011] A further improvement of this utility model is that: a hanging hole with a diameter of 5-8mm is provided at the end of the spoon handle away from the spoon body, and the edge of the hanging hole is provided with a rounded transition structure.

[0012] A further improvement of this utility model is that the edge of the feed inlet of the storage section is provided with an arc-shaped flange with a curvature radius of 3-5mm.

[0013] A further improvement of this utility model is that: the outer wall of the spoon handle is uniformly provided with multiple anti-slip protrusions along its length.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by this utility model includes: The scale lines on the spoon body of this invention can directly indicate the sample quantity, eliminating the need for operators to repeatedly adjust the balance. It is especially suitable for repeated weighing scenarios with fixed sample quantities, significantly shortening the weighing time.

[0015] In this invention, the funnel-shaped spoon body, combined with the pull-out unloading plate, allows for precise release of the sample from the outlet without inverting the spoon, completely solving the problem of spillage when transferring samples by inverting the traditional weighing spoon. At the same time, the sealing strip further prevents the sample from leaking through the gaps in the slide rail during the weighing process, reducing sample loss and the risk of cross-contamination.

[0016] When the sample is transferred to the crucible through the outlet of the funnel-shaped spoon, the operator can move the weighing spoon to make the sample fall evenly along the inner wall of the crucible, directly completing the sample leveling. This eliminates the need for the step of using a glass rod to level the sample in traditional operations, thus simplifying the experimental process.

[0017] The anti-slip protrusions on the handle and the anti-slip texture on the slider of this utility model can increase the friction between the hand and the tool and prevent slipping during use; the hanging hole makes it easy to store the weighing spoon and avoid loss; the arc-shaped flange of the feed port can prevent the sample from scratching the hand when picking up the material and improve the safety of use.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.

[0021] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a funnel-shaped graduated weighing spoon, comprising a spoon body 1 and a spoon handle 2 fixed to the outer wall of the spoon body 1. The spoon body 1 includes a cylindrical storage section 11, and a frustum-shaped discharge section 13 is fixed below the storage section 11. The storage section 11 and the discharge section 13 form a funnel-shaped structure. Both the storage section 11 and the discharge section 13 are integrally injection molded from a transparent, thickened PP material with a thickness of 2.5mm. This thickness ensures the structural strength of the spoon body 1, preventing deformation over long-term use, while also controlling the overall weight for easy hand operation.

[0022] In this embodiment, the feed inlet edge of the storage section 11 is integrally formed with an arc-shaped flange. The radius of curvature of the arc-shaped flange is 4mm, which can effectively prevent the operator's hand from being scratched by the spoon when picking up the material, and at the same time prevent the sample from spilling from the edge of the spoon during the picking process.

[0023] The outer wall of the spoon body 1 is printed with scale lines 12, which are evenly distributed along the height of the storage part 11. The range is 0-100mL. Operators can directly read the sample volume through the scale lines 12 and quickly determine the sample quantity after converting it according to the sample density. There is no need to repeatedly weigh with a balance. It is especially suitable for scenarios where a fixed amount of the same sample is weighed in batches, which greatly improves the efficiency of operation.

[0024] The handle 2 is fixedly connected to the middle of the outer wall of the spoon body 1 and is integrally formed with the spoon body 1. The outer wall of the handle 2 is evenly distributed with anti-slip protrusions. The anti-slip protrusions are hemispherical in shape, which can increase the friction between the hand and the handle 2 and prevent the weighing spoon from slipping when the hand is sweaty. A hanging hole is opened at the end of the handle 2 away from the spoon body 1. The diameter of the hanging hole is 6mm and the edge of the hanging hole is rounded to avoid the rope being cut when hanging. It is convenient to hang and store the weighing spoon when it is not in use, saving laboratory space.

[0025] In this embodiment, a pull-out opening is provided at the connection between the discharge section 13 and the storage section 11. A discharge plate 3, which can seal the bottom of the storage section 11 and can be pulled along the handle 2, is slidably disposed at the connection between the discharge section 13 and the storage section 11. This discharge plate 3 is also made of transparent PP material and is slidably disposed within the pull-out opening. In this embodiment, a slider 4, which can move along the handle 2, is slidably connected to the handle 2. One side of the discharge plate 3 extends outside the spoon body 1 and connects to the slider 4. The surface of the slider 4 is provided with anti-slip texture. Sealing strips for sealing the pull-out opening are provided on the upper and lower sides of the discharge plate 3 at positions corresponding to the pull-out opening. The sealing strips are made of silicone material and fit tightly against the two side edges of the discharge plate 3 to prevent sample powder from leaking from the gap between the discharge plate 3 and the pull-out opening.

[0026] In this embodiment, when the operator holds the spoon handle 2, aligns the feed port of the spoon body 1 with the sample container, scoops up the sample, and observes the scale line 12 at the same time. When the sample amount reaches the required scale, the scooping stops. At this time, the unloading plate 3 is in the closed state, and the sample is sealed in the storage section 11.

[0027] Align the discharge port of the discharge section 13 with the crucible, and the operator pulls the slider 4 with his finger to make the discharge plate 3 slide outward of the spoon body 1. Under the action of gravity, the sample slides down the inner wall of the spoon body 1 into the crucible.

[0028] During the sample drop, slowly rotate the weighing spoon to distribute the sample evenly along the inner wall of the crucible. Once the sample falls into the crucible, it will naturally form a flat accumulation surface without the need to use a glass rod to level it.

[0029] After weighing, push the unloading plate 3 back to the closed position and gently tap the spoon body 1 to remove any remaining sample from the outlet. After cleaning, hang the weighing spoon on the laboratory hook through the hanging hole for easy access next time.

[0030] In the above embodiments, this utility model provides a funnel-shaped graduated weighing spoon. The graduations on the spoon directly indicate the sample volume, eliminating the need for repeated adjustments using a balance. This is particularly suitable for repetitive weighing of fixed sample volumes, significantly reducing weighing time. The funnel-shaped spoon, combined with a pull-out discharge plate, allows for precise sample release from the outlet without inverting the spoon, completely solving the spillage problem associated with traditional inverted weighing spoons. Furthermore, the sealing strip further prevents sample leakage from the slide rail gaps during weighing, reducing sample loss. This invention reduces the risk of sample loss and cross-contamination. When the sample is transferred to the crucible through the outlet of the funnel-shaped spoon, the operator can move the weighing spoon to make the sample fall evenly along the inner wall of the crucible, directly leveling the sample. This eliminates the need for the traditional step of using a glass rod for leveling, simplifying the experimental process. At the same time, the anti-slip protrusions on the spoon handle and the anti-slip texture on the slider increase the friction between the hand and the tool, preventing slippage during use. The hanging hole facilitates the storage of the weighing spoon, preventing loss. The arc-shaped flange of the inlet prevents the sample from scratching the hand when picking up the material, improving safety during use.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
