Example 1

The present invention provides a spoon for laboratory measurement, as shown in FIGS. 1 to 3 , comprising a spoon body 100 , and the spoon body 100 includes:

Spoon handle 10 for grasping;

The spoon head 20 is provided with at least a first step 21 and a second step 22 which are arranged in a high and low position in sequence; the first step 21 is located at the lowest position, and the first step 21 is provided with a first cavity 211; the The second step 22 is provided with at least two second cavities 221 .

In this embodiment, the spoon body 100 improves the spoon head 20 , the spoon head 20 is designed in a stepped shape, and the first step 21 located at the lowest position is provided with a first cavity 211 , and the second step higher than the first step 21 is provided 22 is provided with at least two second cavities 221 . When measuring substances in the laboratory, first dig out the target object through the first cavity 211 of the first step 21, and use a weighing device to weigh it to obtain the weight of this measurement, and then cooperate with the experimenter's measurement experience , according to the estimated weight of the remaining demand and the relationship between the dimensions of the first cavity 211 and the second cavity 221, evaluate the usage of the first cavity 211 and the second cavity 221 during subsequent excavation, thereby reducing the size of the spoon body 100. The number of times of use is reduced, thereby reducing the operational burden of the experimenter.

In one embodiment, the number of cavities of two adjacent steps differs by one, and the number of cavities of the lower step is smaller than the number of cavities of the upper step. That is, the number of the second cavities 221 of the second step 22 is two. When the experimenter measures, the spoon body 100 contacts the first step 21 and the second step 22 in sequence as the depth of the spoon body 100 into the object to be measured deepens. The number of cavities for different steps increases by one from low to high, which is in line with the experimenter's habit of using the spoon body 100, and it is convenient for the experimenter to estimate the required cavity for subsequent weighing, even if the experimenter estimates the spoon body 100 The depth of insertion into the measured object.

Further, the spoon head 20 is in a partially enlarged structure along the direction toward the spoon handle 10 . Specifically, the arrangement of the difference in the number of cavities in different steps facilitates the design of the spoon head 20 to be gradually relaxed from the end of the spoon head 20 away from the spoon handle 10 toward the spoon handle 10, thereby facilitating the insertion of the end of the spoon head 20 to be measured and taken. thing.

In one embodiment, a third step 23 higher than the second step 22 is further included. Specifically, since the overall size of the spoon body 100 is limited, the number of steps cannot be too large, otherwise the size of the spoon head 20 will be too large or the capacity of the cavity will be too small. The spoon head 20 includes a first step 21 , a second step 22 , and a third step 23 , so as to increase the selectivity of the weight that the spoon head 20 can take in a single time, and at the same time reduce the influence on the overall size of the spoon head 20 .

In one embodiment, the volumes of the chambers of different steps are equal, so that the user can estimate the weight condition that the spoon head 20 can take. Specifically, the volume of the cavity is 5ml and the spoon head 20 includes the first step 21 , the second step 22 , and the third step 23 as an example, and the third step 23 is provided with three third chambers 231 . When 20g of the substance needs to be weighed, the first chamber 211 of the first step 21 is filled with the substance to be weighed for the first time, and the weighed substance is weighed. The weight of the substance to be weighed is 5g, then the second time When weighing, the first cavity 211 and the second cavity 221 need to be filled up, and the space of the two third cavities 231 of the third step 23 should be filled into the object to be weighed, and weighed according to the weighing result. Adjust the amount taken for the second time.

In one embodiment, each step is respectively provided with at least one scraper, which is used to scrape the measured material in the corresponding cavity, so as to reduce the measured amount when the same cavity is full in different measuring processes, so that Reduce the error of the measuring part in different measuring processes.

Further, the scraper is rotatably connected to the top wall of the step to facilitate the operation of the scraper. Specifically, in order to simplify the structure of the spoon body 100 , when the scraper is scraping, the scraper can be manually moved by the experimenter. In a specific embodiment, the spoon head 20 includes a first step 21, a second step 22, and a third step 23; Scraping; the second step 22 is provided with two second scrapers 242 for scraping the upper surfaces of the two second chambers 221 respectively; the third step 23 is provided with two third scrapers 243, It is used to scrape the upper surfaces of the three third cavities 231 .

In one embodiment, the spoon body 100 has a symmetrical structure, and the structure is symmetrical and beautiful, which is convenient for processing and design.

In one embodiment, the spoon handle 10 is provided with a friction portion 11 for grasping, so as to increase the friction between the experimenter's head and the spoon handle 10 .

In one embodiment, each cavity is elliptical and extends along the length direction of the spoon body 100 to facilitate the arrangement of multiple cavities on the corresponding steps. In a specific embodiment, the plurality of cavities on the step are arranged in an array along the width direction of the step.

The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form; any person of ordinary skill in the industry can smoothly implement the present utility model as shown in the accompanying drawings and above; However, within the scope of the technical solution of the present invention, any changes, modifications and equivalent changes made by those skilled in the art using the technical contents disclosed above are equivalent to the present invention. At the same time, any alteration, modification and evolution of any equivalent changes made to the above embodiment according to the essential technology of the present invention still belong to the protection scope of the technical solution of the present invention.
