Description

Technical Field

[0001] This utility model belongs to the field of composite film technology, specifically relating to an anti-detachment composite film. Background Technology

[0002] A multi-layered bottom pot is a specially designed cooking utensil that can be used on gas stoves, induction cookers, and other heating devices. Its bottom is composed of two or more layers of materials, which can be metal. The purpose of this design is to improve the pot's heat conductivity, ensure even heat distribution, and thus improve cooking efficiency and even heating of food.

[0003] Stamping is a composite method of cold joining. During installation, a press is used to press the protrusion on the bottom of the pot into the through hole on the bottom plate. Because there is no locking structure between the through hole and the protrusion in this installation method, the gap between the protrusion and the through hole will increase during repeated thermal expansion and contraction, causing the bottom plate to fall off. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-detachment bottom sheet, whose flange is bent into the inside of the through hole, which can reduce the gap inside the through hole, thereby making the protrusion of the pot bottom more tightly pressed into the inside of the through hole, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment backing sheet, comprising a stainless steel disc and a perforated structure, wherein the surface of the stainless steel disc is provided with a perforated structure, and there are a plurality of perforated structures evenly distributed thereon. Each perforated structure includes a through hole and a flange, wherein the through hole is provided on the surface of the stainless steel disc, the flange is provided at the top of the through hole, and the sidewall of the flange is symmetrically provided with through grooves.

[0006] Furthermore, the flange and the stainless steel disc are an integral structure.

[0007] Furthermore, the cross-sectional shape of the through hole is circular, waist-shaped, or elongated.

[0008] Furthermore, the top of the flange is integrally connected with an arc-shaped protrusion.

[0009] Furthermore, the depth of the through hole is D, and the width of the flange is d, wherein the size of D is equal to the size of d.

[0010] Compared with the prior art, the beneficial effects of this utility model are: during pressing, the flange is squeezed by the bulge of the bottom of the pot and bends into the inside of the through hole. After the flange bends into the inside of the through hole, the gap inside the through hole can be reduced, so that the bulge of the bottom of the pot is pressed more tightly into the inside of the through hole, thereby improving the stability of the connection between the bulge and the through hole.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figure 1 and 2 As shown, an anti-detachment backing sheet includes a stainless steel disc 1 and a perforated structure 2. The surface of the stainless steel disc 1 is provided with the perforated structure 2. There are several perforated structures 2, which are evenly distributed. The perforated structure 2 includes a through hole 21 and a flange 22. The through hole 21 is provided on the surface of the stainless steel disc 1, and the flange 22 is provided at the top of the through hole 21. The sidewall of the flange 22 is symmetrically provided with through grooves 23.

[0020] According to the above structure, during installation, the stainless steel disc 1 is placed at the bottom of the pot, and then the bottom plate is pressed onto the bottom of the pot by a press. The protrusion of the bottom of the pot passes through the through hole 21, thereby fixing the bottom plate to the bottom of the pot. During pressing, the flange 22 is squeezed and bent into the inside of the through hole 21. After the flange 22 bends into the inside of the through hole 21, the gap inside the through hole 21 can be reduced, so that the protrusion of the bottom of the pot is pressed more tightly into the inside of the through hole 21, thereby improving the stability of the connection between the protrusion and the through hole 21.

[0021] like Figure 2 As shown, the flange 22 and the stainless steel disc 1 are an integral structure.

[0022] According to the above structure, the integral structure of flange 22 and stainless steel disc 1 is easy to stamp and form in one piece during production, which is convenient for production. Moreover, the integral structure can make the connection between flange 22 and stainless steel disc 1 more stable.

[0023] like Figure 3 As shown, the cross-sectional shape of the through hole 21 is circular, waist-shaped, or elongated.

[0024] Based on the above structure, different shapes can adapt to different shapes of protrusions under different pot bottoms, improving the adaptability of this composite bottom plate.

[0025] like Figure 2 As shown, the top of the flange 22 is integrally connected with an arc-shaped protrusion 3.

[0026] According to the above structure, when the protrusion squeezes the flange 22, the arc-shaped protrusion 3 can hold the protrusion tightly, thereby making the connection between the protrusion and the side wall of the flange 22 more stable.

[0027] like Figure 4 and 5 As shown, the depth of the through hole 21 is D, and the width of the flange 22 is d, with the size of D being equal to the size of d.

[0028] According to the above structure, during installation, the protrusion bends the flange 22 into the through hole 21 by squeezing the flange 22. The width of the flange 22 is equal to the depth of the through hole 21, which can ensure that the flange 22 is completely bent into the through hole 21, avoiding the flange 22 from penetrating the through hole 21 and forming a protrusion, which would affect the flatness of the bottom of the pot.

[0029] The working principle of this utility model is as follows: During installation, a stainless steel circular sheet 1 is placed at the bottom of the pot, and then the bottom sheet is pressed onto the bottom of the pot using a press. The protrusion of the bottom of the pot passes through the through hole 21, thereby fixing the bottom sheet to the bottom of the pot. During pressing, the flange 22 is squeezed and bent into the inside of the through hole 21. After the flange 22 bends into the inside of the through hole 21, the gap inside the through hole 21 is reduced, so that the protrusion of the bottom of the pot is pressed more tightly into the inside of the through hole 21, thereby improving the stability of the connection between the protrusion and the through hole 21. During installation, the protrusion bends the flange 22 into the inside of the through hole 21 by squeezing the flange 22. The width of the flange 22 is equal to the depth of the through hole 21, which ensures that the flange 22 can be completely bent into the interior of the through hole 21, preventing the flange 22 from penetrating the through hole 21 and forming a protrusion that would affect the flatness of the pot bottom. The integral structure of the flange 22 and the stainless steel disc 1 makes it easy to stamp and form in one piece during production, which is convenient for production. Moreover, the integral structure makes the connection between the flange 22 and the stainless steel disc 1 more stable. Different shapes can adapt to different shapes of protrusions under different pot bottoms, improving the adaptability of this composite bottom plate. When the protrusion squeezes the flange 22, the arc-shaped protrusion 3 can hold the protrusion tightly, thereby making the connection between the protrusion and the side wall of the flange 22 more stable.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
