Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cookware, especially to a double bottom pot. BACKGROUND

[0002] The Chinese patent with the publication number CN219438800U discloses a technical solution named double bottom pot, which comprises a pot body, a double bottom part formed at the bottom of the pot body for mounting a double bottom sheet, and a matching protrusion formed around the outer circle of the double bottom part. The double bottom sheet needs to be connected with the pot body through a riveting process. During the process of the die driving the double bottom sheet to be pressed down, the crimping surface will contact the matching protrusion. In the further pressing process, the matching protrusion will be flattened and deformed, and finally the double bottom sheet will be clamped on the double bottom part to form a fixed connection.

[0003] The above-mentioned double bottom pot relies on the deformation of the matching protrusion to clamp the double bottom sheet on the double bottom part. During the deformation process of the matching protrusion, the deformed force is transmitted from the edge of the double bottom sheet to the center, which will leave stress on the double bottom sheet. The main reason for the phenomenon of the double bottom sheet falling off is that the pot bottom expands after being heated, causing the protrusions on the surface of the double bottom sheet to separate from the pot body. However, the release direction of the stress is that the stress will concentrate on the center of the double bottom sheet to form a balance under normal circumstances. However, when the pot body expands and affects the double bottom sheet, the stress will concentrate on the micro protrusions to release, causing the double bottom sheet to deform rapidly. Therefore, the connection between the pot body and the double bottom sheet of the existing double bottom pot needs to be improved. SUMMARY

[0004] In view of the above-mentioned shortcomings of the double bottom sheet of the existing double bottom pot being easily deformed after being affected by the expansion of the pot body, the purpose of the utility model is to provide a double bottom pot with a more reliable connection between the double bottom sheet and the pot body.

[0005] In order to solve the above-mentioned technical problems, the utility model solves the problems through the following technical solutions:

[0006] A double bottom pot comprises a pot body and a double bottom part. The bottom of the pot body forms a mounting position for fixing the double bottom part. A buckle structure is arranged between the double bottom part and the mounting position. The buckle structure comprises a plurality of buckle petals protruding from the double bottom part towards the pot body and a plurality of accommodation grooves recessed on the mounting position for inserting the buckle petals. The side wall of the accommodation groove is recessed to form a buckle groove for buckling the buckle petals during the crimping process of the double bottom part and the pot body.

[0007] When the complex bottom part is slightly protruded due to the influence of the pot expansion, the residual stress in the complex bottom part is released to the slight protrusion, causing the complex bottom part to further protrude until it is separated from the pot. When the clamping lobe is inserted into the accommodation groove and touches the bottom of the accommodation groove, a pressing gap is left between the complex bottom part and the mounting position. When the complex bottom part is subjected to a downward pressure, the part of the clamping lobe close to the clamping groove is first deformed and clamped into the clamping groove. At this time, the complex bottom part is firmly clamped on the mounting position due to the deformation of the clamping lobe, and it is not easy to protrude. After the slight protrusion caused by the stress, the clamping lobe can still limit the further protrusion of the complex bottom part, making the complex bottom part not easy to separate from the pot bottom.

[0008] Preferably, the clamping groove is arranged on the side wall of the accommodation groove close to the bottom of the accommodation groove.

[0009] Preferably, the clamping lobe is vertically protruded on the complex bottom part and the end is bent towards the clamping groove.

[0010] With the above scheme, when the complex bottom part is pressed, the end of the clamping lobe is most likely to deform. The above scheme arranges the clamping groove at the position closest to the end of the clamping lobe, and the end of the clamping lobe is bent towards the clamping groove, so that the clamping lobe can accurately deform and bend into the clamping groove, and the clamping effect is achieved most effectively.

[0011] Preferably, a gap slot is arranged on the side wall of the accommodation groove to provide a gap for the clamping lobe to deform and clamp in when the complex bottom part is pressed with the pot.

[0012] With the above scheme, since the clamping lobe may have deviations in length or thickness during production, when the size is larger, the volume of the deformed clamping lobe will increase, and the complex bottom part surface will protrude due to excessive deformation of the clamping lobe. The gap slot in the present scheme provides a certain amount of deformation redundancy space for the clamping lobe. When the size of the clamping lobe is larger, it can continue to deform and enter the gap slot, reducing the possibility of protrusion of the complex bottom part surface and the requirement for size accuracy of the clamping lobe.

[0013] Preferably, the complex bottom part includes a plurality of complex bottom pieces in the form of a fan ring. Each complex bottom piece includes an inner arc edge, an outer arc edge, and two straight edges connecting the inner and outer arc edges. The complex bottom pieces are combined to form a circular ring. Each complex bottom piece is provided with a pair of clamping lobes on both sides of the straight edges.

[0014] With the above scheme, when the complex bottom part is an integral whole, the closer the clamping lobe is to the stress concentration, the greater the influence it will receive. Therefore, the part of the clamping lobe close to the stress concentration is more likely to fail than the part away from the stress concentration. When the complex bottom part is divided into a plurality of complex bottom pieces, the stress during pressing will be dispersed and will not be concentrated in a certain place, so the stress on each clamping lobe will be more uniform and less likely to fail locally.

[0015] As preferred, the accommodating grooves are distributed between two adjacent complex bottom sheets, and two buckling petals on the adjacent straight edges of the adjacent complex bottom sheets are inserted into the same accommodating groove, and the buckling grooves are arranged on the two side walls of the accommodating groove.

[0016] According to the above scheme, the adjacent buckling petals are extruded after deformation, and the extrusion can make the two buckling petals deform to the two sides. In the scheme, the buckling grooves are arranged on the two side walls of the accommodating groove, so that the buckling petals can be clamped after extrusion. The extrusion of the two buckling petals finally forms an interference fit in the accommodating groove, so that the connection effect is more stable.

[0017] As preferred, the complex bottom part and the mounting position are provided with a pressing assembly capable of pressing and fixing the complex bottom part on the mounting position.

[0018] As preferred, the pressing assembly comprises a pressing petal protruding at the inner arc edge and / or the outer arc edge of the complex bottom sheet, a pressing groove provided on the mounting position and used for placing the pressing petal, and a pressing ring arranged in the pressing groove and extruded with the pressing petal to form an interference fit.

[0019] According to the above scheme, the pressing ring further fixes the complex bottom sheet on the mounting position and forms an interference fit, so that the connection effect is reinforced.

[0020] The complex bottom part is affected by the expansion of the pot body to produce a slight protrusion, and the stress remaining in the complex bottom part is released to the slight protrusion, so that the complex bottom part is further protruded until it is separated from the pot body. When the buckling petal is inserted into the accommodating groove and touches the bottom of the accommodating groove, a pressing gap is left between the complex bottom part and the mounting position. When the complex bottom part is subjected to a downward pressure, the part of the buckling petal close to the buckling groove is first deformed and buckled into the buckling groove. At this time, the complex bottom part is firmly buckled on the mounting position due to the deformation of the buckling petal, and is not easy to protrude. After the slight protrusion is formed under the influence of stress, the buckling petal can still limit the further protrusion of the complex bottom part, so that the complex bottom part is not easy to separate from the pot bottom.

[0029] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0030] Example

[0031] A composite bottom pot, according to Figure 1 As shown, it includes a pot body 1 and a composite bottom component. The bottom of the pot body 1 forms a mounting position 2 for fixing the composite bottom component. The bottom component includes a plurality of fan-shaped composite bottom sheets 7. Each composite bottom sheet 7 includes an inner arc edge, an outer arc edge and two straight edges connecting the inner and outer arc edges. The composite bottom sheets 7 are assembled to form a ring. Figure 1 、 4 As shown, there are several snap-fitting flaps 3 protruding toward the pot body 1 on the composite bottom component, and a receiving groove 4 for the snap-fitting flaps 3 to be inserted into the mounting position 2. In this embodiment, each composite bottom film 7 is provided with a pair of snap-fitting flaps 3 on both sides of the straight edge, and an receiving groove 4 is distributed between every two adjacent composite bottom films 7. The two snap-fitting flaps 3 on the adjacent straight edges of adjacent composite bottom films 7 are inserted into the same receiving groove 4. The side walls on both sides of the receiving groove 4 are recessed to form snap-fitting grooves 5 for the snap-fitting flaps 3 to be deformed and snapped into when the composite bottom component and the pot body 1 are pressed together. The snap-fitting grooves 5 are provided on the side walls of the receiving groove 4 near the bottom of the receiving groove 4. The snap-fitting flaps 3 are vertically protruding on the composite bottom component and the ends are bent toward the snap-fitting grooves 5. The side walls of the receiving groove 4 are provided with a clearance groove 6 for the snap-fitting flaps 3 to be deformed and snapped into when the composite bottom component and the pot body 1 are pressed together to form an avoidance.

[0032] A pressing assembly is provided between the composite bottom component and the mounting position 2, which can press and fix the composite bottom component on the mounting position 2. Figure 6 、 7The compression assembly comprises a compression lobe 8 protruding at the inner arc edge and the outer arc edge of the complex bottom sheet 7, a compression groove 9 provided with the compression lobe 8 on the installation site 2, and a compression ring 10 arranged in the compression groove 9. When the compression ring 10 is pressed into the compression groove 9, it is in interference fit with the compression lobe 8.

[0033] In combination with the above structure, it can be known from the following description that Figures 1 to 7 It can be known that the complex bottom sheet 7 of the complex bottom pot in the embodiment is firmly buckled on the installation site 2 due to the deformation of the buckling lobe 3, and is not easy to protrude. After the buckling lobe 3 is slightly protruded due to stress, it can still limit the complex bottom part from further protruding, so that the complex bottom part becomes not easy to be separated from the pot bottom.

[0034] In the embodiment, the complex bottom part is split into several complex bottom sheets 7, so that the stress during compression is also dispersed and not concentrated in a certain place for release. Therefore, the stress of each buckling lobe 3 is more uniform, and the local failure is not easy to occur.

[0035] Finally, it should be noted that the above description is only the preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features.
