Example 1

The utility model provides a ladle that is used for laboratory volume to get, as shown in fig. 1 to fig. 3, including ladle body 100, ladle body 100 includes:

a spoon handle 10 for grasping;

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

In this embodiment, the spoon head 20 is improved by the spoon body 100, the spoon head 20 is designed to be step-shaped, the first step 21 located at the lowest position is provided with the first containing cavity 211, and the second step 22 higher than the first step 21 is provided with at least two second containing cavities 221. When the material is measured in the laboratory, firstly, the target object is dug through the first containing cavity 211 of the first step 21, the weighing device is adopted for weighing, the weight of the measured quantity is obtained, the experience of measuring the quantity of the experimenter is matched, the weight estimation and the size relation of the first containing cavity 211 and the second containing cavity 221 are obtained according to the residual quantity required to be measured, the service conditions of the first containing cavity 211 and the second containing cavity 221 during the subsequent digging are evaluated, the use times of the spoon body 100 are reduced, and the operation burden of the experimenter is reduced.

In an 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 higher step. That is, the number of the second cavities 221 of the second step 22 is two. When an experimenter gets the measured object, the measured object sequentially contacts the first step 21 and the second step 22 along with the deepening of the depth of the measured object inserted into the spoon body 100. The appearance chamber figure of different steps increases one in proper order from low level to high level, accords with the experimenter to ladle body 100's use habit, and the required appearance chamber that uses is got to the subsequent title of experimenter of being convenient for, even if be convenient for the experimenter to estimate the degree of depth that ladle body 100 inserted in the measured thing.

Further, the spoon head 20 is in a partially enlarged structure along the direction towards the spoon handle 10. Specifically, the arrangement of the number difference of the cavities of different steps facilitates the design of the spoon head 20 into a gradually widening structure from the end thereof far away from the spoon handle 10 toward the spoon handle 10, thereby facilitating the insertion of the end of the spoon head 20 into the object to be weighed.

In one embodiment, a third step 23 is included that is higher than the second step 22. Specifically, because ladle body 100 whole size is limited, the figure of step can not be too big, otherwise lead to spoon head 20 oversize or lead to the capacity of holding the chamber undersize, and then spoon head 20 sets up the stair structure of three steps, and spoon head 20 includes first step 21, second step 22, third step 23 promptly to increase the selectivity of the weight that spoon head 20 single can be got, reduce the influence to spoon head 20 whole size simultaneously.

In one embodiment, the cavities of different steps are of equal volume to facilitate a user in estimating the weight available from the spoon head 20. Specifically, taking the example that the capacity of the accommodating cavity is 5ml and the spoon head 20 comprises the first step 21, the second step 22 and the third step 23, the third step 23 is provided with three third accommodating cavities 231. When 20g of substances are required to be weighed, the first containing cavity 211 of the first step 21 is filled with the measured substances when the substances are weighed for the first time, the weighing is carried out, the weighed substances are weighed, the weight of the measured substances is 5g, the first containing cavity 211 and the second containing cavity 221 are required to be filled when the substances are weighed for the second time, the spaces of the two third containing cavities 231 of the third step 23 are filled with the measured substances, the weighing is carried out, and the second-time measuring and taking are adjusted according to the weighing result.

In one embodiment, each step is provided with at least one scraping plate for scraping the measured object in the corresponding containing cavity, so as to reduce the measured object when the same containing cavity is full in different measuring processes, and reduce the error of the measuring part in different measuring processes.

Further, the scraper is rotatably connected to the top wall of the step, so that the scraper can be operated conveniently. Specifically, in order to simplify the structure of the spoon body 100, when the scraper is scraped, the scraper is manually stirred by an experimenter. In a particular embodiment, the spoon head 20 includes a first step 21, a second step 22, a third step 23; the first step 21 is provided with a first scraping plate 241 for scraping the upper surface of the first cavity 211; the second step 22 is provided with two second scrapers 242 for scraping the upper surfaces of the two second cavities 221 respectively; the third step 23 is provided with two third scrapers 243 for scraping the upper surfaces of the three third cavities 231.

In an embodiment, the spoon body 100 has a symmetrical structure, and the structure is symmetrical and beautiful, thereby facilitating the processing and design.

In one embodiment, the spoon handle 10 is provided with a friction part 11 for gripping, so as to increase the friction force between the head of the experimenter and the grip of the spoon handle 10.

In an embodiment, each of the receiving cavities is oval and extends along the length direction of the spoon body 100, so that the plurality of receiving cavities are conveniently arranged on the corresponding step. 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 is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the utility model can be smoothly implemented by the ordinary technicians in the industry according to the drawings and the above description; however, those skilled in the art should understand that changes, modifications and variations made by the above-described technology can be made without departing from the scope of the present invention, and all such changes, modifications and variations are equivalent embodiments of the present invention; meanwhile, any changes, modifications, evolutions, etc. of the above embodiments, which are equivalent to the actual techniques of the present invention, still belong to the protection scope of the technical solution of the present invention.
