Description

Technical Field

[0001] The utility model relates to the technical field of crucibles, in particular to a crucible that can be stacked and accessed. Background Art

[0002] Crucibles are containers used for melting and refining liquid metals, as well as for heating and reacting solids and liquids. Crucibles are typically made of porcelain and come in sizes of 10, 15, 25, and 50 mL. They are available in porcelain, iron, and alumina crucibles. Crucibles are resistant to high temperatures and are used for burning precipitates, melting salts that don't react with the crucible, and dehydrating crystalline hydrates.

[0003] Generally, multiple crucibles of the same specification are prepared when in use, and when not in use, the multiple crucibles need to be stacked and stored to reduce the occupied space. However, the existing crucibles are easily stuck to each other when stacked together, making it difficult to take out the crucibles individually, making it inconvenient to take out the crucibles. Utility Model Content

[0004] In order to solve the problem that existing crucibles are easily stuck to each other when they are nested together, resulting in difficulty in taking out a single crucible, the utility model provides a crucible that can be stacked and taken out.

[0005] In order to solve the above technical problems, the utility model is realized through the following technical solutions: a stackable and accessible crucible, comprising a crucible body, the diameter of the upper end of the crucible body being larger than the diameter of the lower end face, and limiting blocks being fixed on both sides of the upper end of the crucible body, the upper end of the limiting block being higher than the upper end of the crucible body, a raised card platform being fixed on the upper end of the limiting block, and a card slot cooperating with the card platform being provided at the lower end of the limiting block.

[0006] As a preferred solution, a reinforcing rib is fixed to the outer side of the crucible body near the upper end, and a supporting base is fixed to the lower end of the crucible body.

[0007] As a preferred solution, the support base includes a reinforcement ring fixed to the lower end of the crucible body, and a plurality of support legs are fixed to the lower end of the reinforcement ring.

[0008] As a preferred solution, the crucible body includes an outer crucible body, an inner crucible body is arranged inside the outer crucible body, and a heat-resistant metal skeleton is arranged between the outer crucible body and the inner crucible body.

[0009] As a preferred solution, a taking groove is provided on the outward-facing side of the limit block, and the four corners of the limit block are rounded.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] When two crucible bodies are stacked, the upper and lower limit blocks support each other, and the positioning cooperation between the two limit blocks is achieved through the clamping cooperation between the clamping platform and the clamping slot, which can effectively prevent the two crucible bodies from being tightly fitted to each other, making it convenient to take the crucible body.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0021] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0022] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0023] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0027] like Figure 5 As shown, the crucible body 1 includes an outer crucible body 11, an inner crucible body 12 is arranged on the inner side of the outer crucible body 11, and a heat-resistant metal skeleton 13 is arranged between the outer crucible body 11 and the inner crucible body 12. By arranging the heat-resistant metal skeleton 13 between the outer crucible body 11 and the inner crucible body 12, the strength of the crucible body 1 is greatly enhanced, and the service life of the crucible body 1 is extended.

[0028] like Figure 3 As shown, a picking groove 32 is provided on the outward side of the limit block 3. When picking up the crucible body 1, the fingers are inserted into the picking groove 32 to facilitate picking up the crucible body 1. The four corners of the limit block 3 are rounded to avoid sharp corners causing harm to the operator.

[0029] In this embodiment, when stacking the crucible bodies 1, one of the crucible bodies 1 is placed on the inner side of the other crucible body 1, and the base 31 at the upper end of the lower limit block 3 is clamped in the slot 33 at the lower end of the upper limit block 3 to complete the stacking and storage of the crucible bodies 1.

[0030] The above is a preferred embodiment of the present invention. Technicians in the field of the present invention can also change and modify the above embodiment. Therefore, the present invention is not limited to the above specific embodiment. Any obvious improvements, replacements or modifications made by technicians in this field on the basis of the present invention are within the scope of protection of the present invention.
