Description

Technical Field

[0001] This utility model relates to a construction clamp for simultaneous internal and external spraying of flat-bottomed cookware. Background Technology

[0002] Currently, there are three spraying processes used for surface coating of cookware on the market: 1. Inside-to-outside process, where the inner surface is sprayed first, followed by the outer surface; 2. Outside-to-inside process, where the outer surface is sprayed first, followed by the inner surface; 3. Simultaneous inside-outside spraying process, where both the outer and inner surfaces are sprayed at the same time. The simultaneous inside-outside spraying process is more efficient, so factories usually prefer to use this process.

[0003] The simultaneous internal and external coating process has a critical problem: the bottom of cookware is usually made of a metal-coated sheet, allowing it to be used on induction cooktops. However, during coating application, the paint gets sprayed onto this sheet, affecting its magnetic conductivity. Current technology typically involves attaching protective paper to the sheet for protection, but this primitive method is undeniably inefficient. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings of existing cookware that can be sprayed inside and out at the same time, this utility model provides a construction fixture for spraying flat-bottomed cookware inside and out at the same time, which can conveniently and effectively protect the bottom sheet of the pot during the coating process.

[0005] The technical solution of this utility model to solve its technical problem is: a construction clamp for simultaneous internal and external spraying of flat-bottomed cookware, including a column, a support base fixed at the upper end of the column, a raised ring provided on the upper end surface of the support base, and a magnet provided on the upper end surface of the support base, the magnet being located inside the raised ring.

[0006] The support base has an annular support plate for protecting the bottom of the flat-bottomed cookware. The support plate has a central hole with a diameter equivalent to the outer diameter of the convex ring. After the support plate is placed on the support base, the support plate extends outward on the support base, the convex ring is located in the central hole, and the thickness of the support plate is greater than or equal to the protrusion height of the convex ring. The magnet does not extend upward beyond the convex ring.

[0007] Furthermore, the magnet is flush with the convex ring, and the support plate is flush with the convex ring.

[0008] Furthermore, the support base and support plate are both made of aluminum, and the column is made of stainless steel; the support base and the column are fixed together by a first screw.

[0009] Furthermore, the support base has a first screw hole at its center, the column has a fixing plate inside, and the first screw passes through the first screw hole and further into the fixing plate.

[0010] Furthermore, the magnet is fixed to the support base by a second screw.

[0011] Furthermore, a second screw hole is provided in the center of the magnet, and the second screw passes through the second screw hole and further into the support base.

[0012] Furthermore, the support plate has an inwardly inclined bevel along its back edge.

[0013] The beneficial effects of this utility model are as follows: it provides a construction fixture for simultaneous spraying of coatings inside and outside flat-bottomed cookware, which can conveniently and effectively protect the bottom sheet of the cookware when the coating is sprayed inside and outside the cookware at the same time.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figures 1-6 A construction clamp for simultaneous internal and external spraying of flat-bottomed cookware includes a column 1, a support base 2 fixed at the upper end of the column 1, a raised ring 3 on the upper end surface of the support base 2, and a magnet 4 located inside the raised ring 3 on the upper end surface of the support base 2.

[0022] An annular support plate 7 for protecting the bottom of the flat-bottomed cookware 5 is placed on the support base 2. The support plate 7 has a central hole with a diameter equivalent to the outer diameter of the convex ring 3. After the support plate 7 is placed on the support base 2, the support plate 7 extends outward on the support base 2. The convex ring 3 is located in the central hole, thereby limiting and positioning the support plate 7. The thickness of the support plate 7 is greater than or equal to the protrusion height of the convex ring 3, and the magnet 4 does not extend upward beyond the convex ring 3, so that the flat-bottomed cookware 5 can be placed on the support plate 7.

[0023] In use, after the support plate 7 is placed on the support base 2, the flat-bottomed pan 5 can be placed on the support plate 7, with the bottom surface of the flat-bottomed pan 5 resting on the support plate 7. The bottom sheet 6 on the bottom surface of the flat-bottomed pan 5 is at least partially covered by the support plate 7, leaving only a small central portion of the bottom sheet 6 uncovered. This effectively protects the bottom sheet 5 when the inner and outer sides of the flat-bottomed pan 5 are sprayed with paint simultaneously. Simultaneously, since the bottom sheet 5 is made of iron, it can be attracted by the magnet 4, thus fixing the flat-bottomed pan in place on the support plate 7. To facilitate spraying and achieve uniform spraying, the column 1 can be connected to a drive system (e.g., a belt drive mechanism) to allow the column to rotate.

[0024] In one embodiment, the magnet 4 is flush with the convex ring 3, and the support plate 7 is flush with the convex ring 3, so that the bottom surface of the flat-bottomed cookware 5 can be flatly attached to the support plate 7, the convex ring 3, and the magnet 4, thus better protecting the bottom sheet 6. Of course, the aforementioned "flush" refers to being basically flush, because absolute flush is impossible; it is sufficient to achieve the effect that the bottom surface of the flat-bottomed cookware 5 can be flatly attached to the support plate 7, the convex ring 3, and the magnet 4.

[0025] In one embodiment, both the support base 2 and the support plate 7 are made of aluminum, while the column 1 is made of stainless steel. The reason for preferably using aluminum for the support base 2 and the support plate 7 is that, in production practice, the dimensions of the bottom plates of various flat-bottomed cookware differ, thus requiring different support plates 7 to protect the bottom plates. The aluminum support plate 7 is not affected by magnets during replacement, making it easy to remove or place. Furthermore, the aluminum support base 2 simplifies the installation of the magnet 4 and allows it to focus on attracting the bottom plate 6.

[0026] In one embodiment, the support base 2 and the column 1 are fixed together by a first screw 8. Specifically, the support base 2 has a first screw hole at its center, the column 1 has a fixing plate 9 inside, and the first screw 8 passes through the first screw hole and further into the fixing plate 9 to facilitate the fixing between the support base 2 and the column 1.

[0027] In one embodiment, the magnet 4 and the support base 2 are fixed together by a second screw 10. Specifically, the magnet 4 has a second screw hole in its center, and the second screw 1 passes through the second screw hole and further into the support base 2 to facilitate the fixing between the magnet 4 and the support base 2.

[0028] In one embodiment, the support plate 7 is inclined inward at its back edge to form a bevel 11. The advantage of this structure is that the support plate 7 is inclined inward at its back edge to form a bevel 11, making the support plate 7 very thin at its edge and forming a bevel. At this time, the sprayed paint is not easy to stay at the edge of the support plate 7, but is easy to leave the edge of the support plate 7 along the bevel 11, thereby preventing the paint from sticking between the bottom surface of the flat-bottomed cookware 5 and the support plate.
