[0003] When conducting stability tests on metal and mixed reference materials, they are usually stirred and mixed to ensure the accuracy of the tests. Although most existing metal and mixed reference materials can be easily stirred using a stirring mechanism, some can only be stirred by a single rotation. This method results in the inability to quickly change the stirring position during mixing, leading to problems such as low mixing efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stability testing device for metal and mixed series standard substances, comprising a testing mechanism, a base ring fixedly mounted on the surface of the testing mechanism, an elastic component fixedly mounted on the surface of the base ring, a positioning cup fixedly mounted on the end of the elastic component away from the base ring, an external guide plate fixedly mounted on the inner side of the testing mechanism, an external sliding plate slidably mounted on the inner side of the external guide plate, a motor body fixedly mounted on the surface of the testing mechanism, a gear body fixedly mounted on the output end of the motor body, and an extension rod fixedly mounted on the surface of the positioning cup.

[0006] Preferably, an internal guide rod is slidably installed on the inner side of the external sliding plate, and a second spring is slidably sleeved on the surface of the internal guide rod. The two ends of the second spring are respectively fixedly installed on the surface of the external sliding plate and the inner side of the external guide plate.

[0007] Preferably, teeth are fixedly installed on the surface of the gear body, and the teeth are arranged at one-quarter of the surface of the gear body.

[0008] Preferably, the surface of the external sliding plate is provided with tooth grooves, and the surfaces of the teeth are engaged with the inner wall of the tooth grooves.

[0009] Preferably, the shape of the external sliding plate surface is an inclined surface.

[0010] Preferably, a built-in spacer plate is slidably installed on the inner side of the positioning cup cylinder, and the surface of the built-in spacer plate is inclined.

[0011] Preferably, a positioning cup groove is provided on the inner side of the positioning cup cylinder, and a reagent testing cylinder is slidably installed on the inner wall of the positioning cup groove on the positioning cup cylinder.

[0012] Preferably, there are two sets of positioning cups, with auxiliary sliders rotatably mounted on the inner side of each set of positioning cups, and auxiliary guide rods fixedly mounted on the opposite sides of the two sets of auxiliary sliders.

[0013] Preferably, an internal slide rod is slidably installed on the inner side of the internal spacer plate, and one end of the internal slide rod away from the internal spacer plate is fixedly installed on the inner side of the positioning cup.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In the stability testing device for metal and mixed series standard substances, after the teeth on the gear body separate from the tooth groove on the external slide plate, the external slide plate is driven to reset by the tension of the second spring. At this time, the positioning cup is driven to reset by the elasticity of the bent elastic component. At this time, the metal and mixed series standard substances inside the reagent testing tube can also be shaken when they are stirred and mixed. This improves the effect of shaking and stirring when the metal and mixed series standard substances are tested, thereby ensuring the efficiency of the mixing operation of the metal and mixed series standard substances and the ease of shaking and stirring the metal and mixed series standard substances.

[0016] (2) The stability testing device for metal and mixed series standard substances is pushed by the elasticity of the compressed first spring to form a squeeze limit on the built-in distance plate. Then the stirring mechanism on the testing mechanism descends into the reagent testing cylinder for stirring and mixing. This stirring method is the existing method and will not be marked or explained in the figure.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-4This utility model provides a technical solution: a stability testing device for metal and mixed series standard substances, including a testing mechanism 1, a base ring 2 fixedly installed on the surface of the testing mechanism 1, an elastic component 3 fixedly installed on the surface of the base ring 2, a positioning cup 4 fixedly installed at the end of the elastic component 3 away from the base ring 2, a positioning cup groove 5 is opened on the inner side of the positioning cup 4, and a reagent testing tube 6 is slidably installed on the inner wall of the positioning cup groove 5 on the positioning cup 4.

[0028] Specifically, when it is necessary to perform stability testing on the metal and mixed series of standard substances inside the reagent testing cylinder 6, the elastic component 3 assists in shaking the reagent testing cylinder 6 inside the positioning cup cylinder 4, thereby improving the speed and completeness of mixing the metal and mixed series of standard substances inside the reagent testing cylinder 6.

[0029] Furthermore, an internal spacer plate 7 is slidably installed on the inner side of the positioning cup cylinder 4, and an internal slide rod 8 is slidably installed on the inner side of the internal spacer plate 7. One end of the internal slide rod 8 away from the internal spacer plate 7 is fixedly installed on the inner side of the positioning cup cylinder 4. A first spring 9 is slidably sleeved on the surface of the internal slide rod 8. The two ends of the first spring 9 abut against the surface of the internal spacer plate 7 and the inner side of the positioning cup cylinder 4, respectively. The surface of the internal spacer plate 7 is an inclined surface.

[0030] Specifically, when a reagent testing cylinder 6 containing metal and mixed series standard substances needs to be placed inside the positioning cup 4, the reagent testing cylinder 6 will press against the inclined surface of the built-in spacer plate 7 until the reagent testing cylinder 6 reaches the predetermined position inside the positioning cup 4. At this time, the reagent testing cylinder 6 will be pushed by the elasticity of the compressed first spring 9 to make the built-in spacer plate 7 press and limit it. Then, the stirring mechanism on the testing mechanism 1 descends into the reagent testing cylinder 6 to stir and mix. This stirring method is the existing method and will not be marked or explained in the figure. This ensures that reagent testing cylinders 6 of different sizes have convenient positioning effect when placed inside the positioning cup 4.

[0031] Furthermore, there are two sets of positioning cup cylinders 4. The inner side of the two sets of positioning cup cylinders 4 is rotatably installed with auxiliary sliders 10, and the opposite side of the two sets of auxiliary sliders 10 is fixedly installed with auxiliary guide rods 11. Thus, the two sets of positioning cup cylinders 4 are limited by the connection between the auxiliary sliders 10 and the auxiliary guide rods 11, thereby causing one set of positioning cup cylinders 4 to move, and the other set of positioning cup cylinders 4 will also move accordingly.

[0032] Furthermore, an external guide plate 12 is fixedly installed on the inner side of the inspection mechanism 1, an external slide plate 13 is slidably installed on the inner side of the external guide plate 12, an internal guide rod 14 is slidably installed on the inner side of the external slide plate 13, a second spring 15 is slidably sleeved on the surface of the internal guide rod 14, and the two ends of the second spring 15 are respectively fixedly installed on the surface of the external slide plate 13 and the inner side of the external guide plate 12. A motor body 16 is fixedly installed on the surface of the inspection mechanism 1, a gear body 17 is fixedly installed on the output end of the motor body 16, teeth 18 are fixedly installed on the surface of the gear body 17, and teeth 18 are set at a quarter position on the surface of the gear body 17. A tooth groove 19 is opened on the surface of the external slide plate 13, and the surface of the teeth 18 is meshed with the inner wall of the tooth groove 19. An extension rod 20 is fixedly installed on the surface of the positioning cup 4, and the shape of the surface of the external slide plate 13 is an inclined surface.

[0033] Specifically, when it is necessary to shake and stir the reagent testing cylinder 6 inside the positioning cup 4, the motor body 16 drives the gear body 17 to rotate. The gear body 17 then adjusts by meshing its teeth 18 with the tooth grooves 19 on the outer sliding plate 13, causing the outer sliding plate 13 to rise inside the outer guide plate 12. At this time, the outer sliding plate 13 pushes the extension rod 20 to move through its inclined surface, thus causing the extension rod 20 to tilt the positioning cup 4. After the teeth 18 on the gear body 17 separate from the tooth grooves 19 on the outer sliding plate 13... Therefore, the external sliding plate 13 is reset by the tension of the second spring 15. At this time, the positioning cup 4 is reset by the elasticity of the bending elastic component 3. At this time, the metal and mixed series standard substances inside the reagent testing cylinder 6 can also be shaken when they are stirred and mixed. This improves the effect of shaking and stirring when the metal and mixed series standard substances are tested, thereby ensuring the efficiency of the mixing operation of the metal and mixed series standard substances and the ease of shaking and stirring the metal and mixed series standard substances.

[0034] Working principle: A stability testing device for metal and mixed series standard substances. When the reagent testing cylinder 6 inside the positioning cup 4 needs to be shaken and stirred, the motor body 16 drives the gear body 17 to rotate. The gear body 17 adjusts by meshing its teeth 18 with the tooth grooves 19 on the outer slide plate 13, causing the outer slide plate 13 to rise inside the outer guide plate 12. At this time, the outer slide plate 13 pushes the extension rod 20 to move through its inclined surface. Therefore, the extension rod 20 causes the positioning cup 4 to tilt. When the teeth 18 on the gear body 17 separate from the tooth grooves 19 on the outer slide plate 13, the outer slide plate 13 is driven back to its original position by the tension of the second spring 15. At this time, the positioning cup 4 is driven back to its original position by the elasticity of the bending elastic component 3.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
