Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of experimental tools, and in particular relates to a solid standard material sampling tool. Background Art
[0002] Standard substances used in food testing experiments, such as benzoic acid, triphosphate, and sodium saccharin, are stored in reagent bottles. Since the amount of standard substances used in testing is small, the specifications of the reagent bottles used are generally 10 mg / bottle. This type of reagent bottle has the following characteristics: small size, narrow bottle mouth, and arc-shaped structure inside the bottle. However, the sampling spoon used for weighing samples is generally large in size, which makes it difficult to remove the reagents and there is a lot of residual reagents on the inner wall of the bottle. Utility Model Content
[0003] The utility model provides a solid standard material sampling tool to solve the above technical problems.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] Furthermore, the width of the elastic strip is greater than the width of the arc-shaped plate.
[0007] Furthermore, the arc length of the arc plate is 0.4-0.7 times the arc length of the sampling head.
[0008] Furthermore, the longitudinal longitudinal line of the arc-shaped plate coincides with the longitudinal midline of the sampling head.

[0010] Furthermore, the length of the slot is preferably such that when the push rod is pushed forward, the arc-shaped plate can push the elastic strip into a convex strip.
[0011] Furthermore, a clamping hole is provided at the end of the grip rod not close to the sampling head, and the clamping hole is provided at the end of the slot close to the sampling head and the two are perpendicular to each other; a locking bead is provided on the push rod, and the locking bead can be clamped into the clamping hole.
[0012] Furthermore, the sampling head further comprises: a scraper with an arc-shaped structure, with two ends rotatably arranged outside the sampling head, so that the scraper can rotate up and down relative to the sampling head.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The spherical structure of the sampling head makes it easy to insert it into the reagent bottle; and the push rod of the scraping assembly can push the arc plate forward to push the elastic strip up to a convex strip shape.

[0023] In order to facilitate a better understanding of the present invention, the following examples are used to illustrate the present invention in conjunction with the accompanying drawings. These examples belong to the protection scope of the present invention, but do not limit the protection scope of the present invention.
[0024] Example 1
[0025] A solid standard material sampling device, such as Figure 1-Figure 3 As shown, it includes: a grip rod 1; a sampling head 2, which is a spherical structure and is arranged at the end of the grip rod 1; a cavity 21 is arranged in the sampling head 2; a scraping assembly 3, including: a push rod 31, one end of which extends into the cavity 21, a push rod 32, which is arranged at the end of the push rod 31 in the cavity 21, and an arc plate 33, which is arranged at the end of the push rod 32 not close to the push rod 31; the push rod 31 is arranged along the length direction of the grip rod 1; an elastic strip 22 is arranged at the position of the arc plate 33 relative to the sampling head 2.
[0026] How to use: first push the push rod forward to the appropriate position, so that the arc plate moves forward and the elastic strip is lifted up to form a convex strip; hold the grip and push rod, insert the sampling head into the reagent bottle, and use the convex strip to scrape out the residual reagent in the reagent bottle; after scraping, pull the push rod backward to move the arc plate backward, and the elastic strip returns to its initial position, flush with the outer surface of the sampling head; when different reagents need to be scraped, the sampling head should be cleaned after each use and dried before use.
[0027] Example 2
[0028] like Figure 1 , Figure 3 As shown, the width of the elastic strip 22 is greater than the width of the arc-shaped plate 33 .
[0029] like Figure 1 , Figure 3 As shown, the arc length of the arc plate 33 is 0.4-0.7 times the arc length of the sampling head 2.
[0030] like Figure 1 , Figure 3 As shown, the longitudinal longitudinal line of the arc-shaped plate 33 coincides with the longitudinal center line of the sampling head 2 .
[0031] To scrape the reagents remaining on the inner wall of the reagent bottle, the convex strips formed by the thrust of the elastic strips need to be used. Therefore, the sizes of the arc plate and the elastic strips need to be specified accordingly to ensure that they can meet the requirements of use; the arc plate coincides with the longitudinal midline of the sampling head, so that the arc plate corresponds to the top position of the sampling head (with Figure 1 As a reference), it is convenient for the top of the sampling head to perform scraping operations in the reagent bottle.
[0032] Example 3
[0033] like Figure 1-Figure 4As shown, a mounting hole 11 communicating with the cavity 21 is provided in the grip 1, and a slot 12 is provided at one end of the mounting hole 11 not close to the sampling head 2; the slot 12 is oriented in the same direction as the mounting hole 11 and the two are connected; a push rod 31 is provided in the mounting hole 11.
[0034] like Figure 1-Figure 4 As shown, the length of the slot 12 is preferably such that when the push rod 31 is pushed, the arc plate 33 can push the elastic strip 22 into a convex strip.
[0035] like Figure 1-Figure 4 As shown, a locking hole 13 is provided at the end of the grip 1 not close to the sampling head 2, and the locking hole 13 is provided at the end of the slot 12 close to the sampling head 2 and the two are perpendicular to each other; a locking ball 34 is provided on the push rod 31, and the locking ball 34 can be locked into the locking hole 13.
[0036] Placing the push rod in the installation hole can limit it and prevent the push rod from shaking too much during use due to the lack of restriction; the forward pushing distance of the push rod is limited by the length of the slot. If the push rod is pushed forward too far, the elastic strip will be deformed too much and its recovery will be affected; the set locking bead can be inserted into the card hole after the push rod is pushed to the appropriate position, so that the push rod can be clamped and limited to avoid shaking during use; when the locking bead is pressed, it will move down and away from the card hole, so that the push rod can continue to be pushed and pulled.
[0037] Example 4
[0038] like Figure 1 , Figure 3 , Figure 4 As shown, the sampling head 2 further includes: a scraper 23 with an arc-shaped structure, with two ends rotatably disposed outside the sampling head 2 so that the scraper 23 can rotate up and down relative to the sampling head 2.
[0039] The scraper provided can scrape the outer surface of the sampling head after the scraping is completed and the elastic strip is reset, so as to avoid the waste of the reagent adhered to the sampling head during the scraping process.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the statement "including an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
