However, the heat insulation column is just a simple cavity. After the screw passes through and is threadedly connected and fixed, the assembly can be completed. Furthermore, during use at this time, a screwdriver and screws need to be added, and the increase of materials makes the assembly process cumbersome. Summary of the Utility Model

Detailed Embodiments

[0027] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0028] See attached Figure 1 As shown, in the prior art, the base 200 and the heat preservation cover 300 are first inserted through the heat insulation column 100, and then the screws 400 are inserted and fastened together using a screwdriver to complete the assembly, which requires two components and two operating steps to complete.

[0029] See attached Figure 1-4 As shown, the heat-insulating column for assembling cooking utensils in this embodiment utilizes extrusion force during assembly so that the guide portion passes through the assembly cavity and then resets to complete the assembly.

[0030] In this embodiment, a base 200 is provided, in which an assembly cavity 210 is formed; the bottom of the assembly cavity 210 is a heat preservation cover 300. In this embodiment, the base 200 is recessed inward to form a protective cavity, and the assembly cavity 210 is arranged at a position of the protective cavity close to the heat preservation cover, thereby performing local protection by using the protective cavity.

[0031] In the present embodiment, a heat-insulating column 100 whose end forms an insertion portion 110 is selected, and then the heat-insulating column 100 directly passes through the insertion portion 110 and the guide portion 120 on the insertion portion 110 to complete the entire assembly. In the present embodiment, a gap 500 is formed between the guide portions 120, and the guide portions 120 are elastic members. At the same time, a containment cavity is formed between the guide portions 120, and a deformation avoidance space is formed in the containment cavity. When subjected to force, the containment cavity shrinks, and the guide portions 120 all move toward the deformation avoidance space, so that the insertion portion 110 becomes smaller, and then it is easy to pass through the smaller assembly cavity 210. After the assembly is completed, the guide portion 120 at the insertion portion 110 has passed through the assembly cavity 210. After there is no external force squeezing, it returns to its original state to form a larger containment cavity to support the thermal insulation cover to complete the assembly.

[0032] In this embodiment, the guide part 120 is changed, and the insertion part 110 guides the insertion to complete the assembly, and then the assembly is completed in one step, without installing the heat insulation column first and then adding screws. The whole assembly process and steps are simple. At the same time, the utility model replaces the original double combination assembly of the heat insulation column and the screws with a heat insulation column, which has a simple structure and saves more raw materials.

[0033] Furthermore, to facilitate the assembly of the heat insulation column into the guiding part 120, a guiding inclined surface 121 that faces the heat preservation cover 300 and inclines inward is formed on the surface of the guiding part 120. By forming an inward-inclined inclined surface, it is easier to pass through the assembly cavity, enabling the guiding inclined surface to drive the entire guiding part to complete the assembly and insertion process.

[0034] In this embodiment, for the convenience of production and processing, the inner wall of the guiding part 120 is an arc structure, and a frustum structure that inclines inward is formed between adjacent guiding parts 120 from top to bottom. In this embodiment, the guiding part 120 forms a frustum structure, making the outer surface also an arc structure. During contact and assembly, it is not only easy to pass through but also has little wear.

[0035] To ensure the firmness after assembly and prevent detachment after long-term use, in this embodiment, a clamping part 130 that abuts against the inner wall of the heat preservation cover 300 is provided on the outside of each guiding part 120. By using the clamping part 130, the other end of the heat insulation column 100 that passes through the assembly cavity clamps the heat preservation cover 300 and the base 200 tightly, thereby achieving a non-detachable and firm assembly.

[0036] For the convenience of production and to simplify the mold, in this embodiment, the outer side surface of the clamping part 130 is located at the extension line of the guiding part 120. In this embodiment, it is directly set on the extension line, so that the mold structure is symmetrical and simple, facilitating production.

[0037] Specifically, to form a stable support and clamping, the clamping part 130 is a triangular prism structure, and a limiting surface 131 that abuts against the inner wall of the heat preservation cover 300 is formed above the triangular prism structure. In this embodiment, the limiting surfaces abut against each other, thereby completing a good limiting and clamping to prevent detachment during later assembly. Here, the limiting surface can be a quadrilateral surface, and its contact width with the heat preservation cover is not less than 10 mm.

[0038] In this embodiment, the number of guiding parts 120 can be 3, 4, or 6. Since the entire structure is relatively small, 4 is preferably selected. A cube-shaped gap is formed between the 4 guiding parts, which is not only beautiful but also stable during deformation and force application.

[0039] In this embodiment, a pressing cover 140 for pressing the base is provided above the heat insulation column 100, and the projection of the pressing cover 140 covers the limiting surface 131. In this embodiment, the width of the pressing cover is greater than the width of the limiting surface 131. After assembly, the bottom is firmly assembled with the base 200. By selecting more contact surfaces, the purpose is that the base is below, and sufficient consideration needs to be given to contact fixation.

[0040] Compared with a simple gap, the heat insulation column 100 includes a heat insulation column body 150, and the gap 500 at the insertion end 110 extends to the bottom of the heat insulation column body 150, and the extension length is two-thirds to 1.5 times the length of the end gap 500. In this embodiment, compared with simply setting a gap at the inclined guiding portion 120, in this embodiment, the gap also extends to the cylindrical body, so that the deformed or inwardly retracted part is increased, and thus the assembly can pass through the assembly cavity 210 to achieve better assembly.

[0041] In order to further complete the assembly, an external thread is formed on the outer periphery of the heat insulation column 100, and a matching internal thread is formed on the inner wall of the assembly cavity 210. Thus, in the whole assembly, a better assembly tooling is completed through the process of rotating and assembling at the same time.

[0042] In the present utility model, through the arrangement of the insertion portion and the like, the use of materials is reduced, and the operation method is faster.

[0043] Referring to the attached drawings, in this embodiment, a cross slot is directly opened at the end of the heat insulation column 100 and the middle is hollowed out, which can increase the deformation amount to achieve assembly. At the same time, a clamping portion for forming a limit by extending is arranged on the side portion. The assembly portion of the base and the heat preservation cover is clamped and fixed by opening the tail and the gland, improving the assembly efficiency and stability. In this embodiment, the width of the gap is at least one-half of the width of the guiding portion, so as to provide enough space for deformation and facilitate the inward retraction of the guiding portion to pass through the entire assembly cavity.

[0044] In actual use, the heat preservation cover and the base can also be first assembled in cooperation, and then the heat insulation column is used to first pass through the heat preservation cover and then be fixed to the base. The assembly sequence at this time is from bottom to top, which can be replaced with the top-to-bottom in the previous embodiment.
