Description

Technical Field

[0001] This utility model belongs to the technical field of experimental instruments, and in particular relates to a weighing spoon. Background Technology

[0002] Weighing spoons are a commonly used tool in chemical, biological, and other experiments, used to add various powdered and crumbly reagents, fluxes, or materials during the experiment. However, the volume of existing weighing spoons is usually not adjustable, making it unsuitable for accurately weighing different amounts of material. Experimenters must repeatedly add and remove material to obtain the required quantity, resulting in low work efficiency.

[0003] Weighing spoons are essential for weighing samples on a balance, especially for very small quantities (e.g., 10mg-1000mg). Weighing must be done within a specified range, generally ±10%. For example, to weigh 50mg, the allowable sample size is 45-55mg; otherwise, the test data will be affected. When weighing, gently hold the weighing spoon with one hand and gently tap it with the other to make the sample vibrate and fall. Inexperienced weighers often overweigh samples. After zeroing a precision balance, it's generally possible to add sample, not subtract it, as this will cause inaccurate weighing. Overweighing requires re-weighing, which is very time-consuming. Therefore, we urgently need a weighing spoon that can solve these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a weighing spoon to solve the problem mentioned in the background that when weighing samples on a balance, multiple weighings are caused by the user's subjective error, requiring recalibration and weighing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A weighing spoon includes a handle, characterized in that a spoon head is connected to the front end of the handle, a groove is provided at the upper end of the spoon head, a pusher plate is slidably fitted in the groove, and the pusher plate is connected to a pusher structure disposed inside the handle.

[0006] Preferably, the pushing structure is an elastic pushing structure, including a push rod connected to one side of the push plate. The push rod is laterally slidably fitted inside the handle and its end extends out of the other end of the handle. The other end of the push rod is connected to a pressing part, and a spring wrapped around the push rod is connected between the pressing part and the handle.

[0007] Preferably, the pressing part is a circular pressing plate, and the outer side of the pressing plate is provided with anti-slip protrusions.

[0008] Preferably, the groove is a groove structure with a semi-circular cross-section, and the push plate is a semi-circular structure that matches the cross-section of the groove, with the groove and the push plate fitting tightly together.

[0009] Preferably, the spoon head and the push plate are both made of stainless steel.

[0010] Preferably, the front end of the groove of the spoon head has a smoothly transitioned converging groove structure.

[0011] Preferably, the push rod has a rectangular cross-section, and the push rod slides in conjunction with the hand handle to ensure that the push rod can only move laterally.

[0012] Preferably, the upper end of the spoon head is connected to a baffle plate placed on one side of the groove. The length of the baffle plate, when the spring is in its natural state, can block the groove area between the push plate and the side wall of the groove.

[0013] Preferably, the handle is provided with auxiliary gripping parts on both sides, and the gripping parts are finger grips made of elastic material.

[0014] The beneficial effects of this utility model are as follows: This utility model includes a hand handle, with a spoon head connected to the front end of the hand handle. A groove is provided at the upper end of the spoon head, and a pusher plate slides within the groove. The pusher plate is connected to a pusher structure located inside the hand handle. This utility model makes the weighing spoon into a semi-circular groove with a pusher rod inside. The front of the pusher rod has a push head that fits tightly into the groove, and a spring behind the pusher rod provides a reaction force to slowly push the rod. This design eliminates concerns about excessive force causing samples to fall during weighing, thus saving time. During the thumb-pressing and pushing process, a finger grip ensures the stability of the entire spoon body during use, allowing for single-handed operation while maintaining stability. After weighing, the spring automatically resets. This structure is simple in construction, convenient to use, highly practical, and suitable for widespread application. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0023] Example 1: A weighing spoon includes a handle 1, with a spoon head 2 connected to the front end of the handle 1. A groove 3 is provided on the upper end of the spoon head 2, and a pusher plate 4 is slidably fitted inside the groove 3. The groove 3 has a semi-circular cross-section, and the pusher plate 4 has a semi-circular structure that matches the cross-section of the groove 3. The groove 3 and the pusher plate 4 fit tightly together, so that the pusher plate 4 can completely push the sample towards the front end. Both the spoon head 2 and the pusher plate 4 are made of stainless steel to avoid contamination of the sample during secondary use. The front end of the groove 3 of the spoon head 2 is a smoothly transitioned converging groove structure 10, which facilitates the smooth outward movement of the sample from the converging groove structure 10 during sample feeding, preventing it from concentrating in the groove 3 within the spoon head 2. The extreme position of the push plate 4 is the length of the groove 3. The push plate 4 is connected to a push structure 5 located inside the handle 1. By holding the handle 1 and then using the push structure 5, the sample can be slowly dropped to the desired weighing position, thus avoiding weighing errors. The operation is simple, convenient, and highly practical.

[0024] In Example 2, based on Example 1, the pushing structure 5 is an elastic pushing structure 5, including a push rod 6 connected to one side of the pushing plate 4. The push rod 6 is laterally slidably fitted within the handle 1 and its end extends beyond the other end of the handle 1. The cross-section of the push rod 6 is rectangular. The push rod 6 and the handle 1 are slidably fitted, ensuring that the push rod 6 can only move laterally, allowing it to move only in the handle 1 along the lateral direction. This allows the pushing plate 4 to move only within the groove 3, completing the sample pushing operation. The other end of the push rod 6 is connected to a pressing part 7, which is a circular pressing plate. The outer side of the pressing plate is provided with anti-slip protrusions 9 to prevent the user's hand from slipping during the pushing process. A spring 8 is connected between the pressing part 7 and the handle 1, wrapped around the push rod 6. The spring 8 provides a reaction force to provide a certain resistance during the pushing process. After the pushing is completed, the push rod 6 and the pushing plate 4 return to their initial positions. This embodiment uses an elastic pushing structure 5, which can effectively push the sample slowly and avoid excess sample falling onto the balance, causing weighing failure.

[0025] In Example 3, based on Example 2, a baffle plate 11 is connected to the upper end of the spoon head 2 and placed on one side of the groove 3. When the spring 8 is in its natural state, the length of the baffle plate 11 can block the groove 3 area between the push plate 4 and the side wall of the groove 3. That is to say, when scooping the sample, since the spring 8 is in its natural state, the baffle plate 11 can prevent the sample from entering the groove 3 area formed by the push plate 4 and the groove 3, so that this part of the sample cannot be pushed by the push plate 4.

[0026] In Example 4, based on Example 1, auxiliary gripping parts 12 are provided on both sides of the handle 1. The gripping parts 12 are made of elastic material and have a structure that can hold two fingers of the user to ensure stability during use. Since the user usually operates with one hand during the pushing process, the gripping parts ensure the stability of the entire spoon body during use, so that the user can operate with one hand while ensuring stability.

[0027] In use, the user holds their index and middle fingers in the grip, then scoops the sample into the groove 3 using the spoon. The user then pushes the pressing plate at the end with their thumb, compressing the spring 8. This spring 8 contracts, pushing the pusher plate 4 within the groove 3, causing the sample to slowly fall onto the balance through the constricted groove structure. This avoids re-weighing due to multiple weighings. The weighing spoon is designed as a semi-circular groove 3 containing a pusher 6. The pusher 6 has a push head that fits snugly into the groove 3, and a spring 8 at the back that provides a reaction force, allowing the pusher 6 to slowly move. This design eliminates the worry of excessive force causing multiple weighings and saving time. After weighing, the spring 8 automatically returns to its original position. This structure is simple, easy to use, and highly practical, making it suitable for widespread adoption.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
