DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] Embodiment 1:

[0021] This embodiment provides a metal casting handle for compact shelving, such as Figure 1 , Figure 2 As shown, it includes a turntable 1 and a handle 2, one end of the handle 2 is connected to the turntable 1; the turntable 1 includes a first ring wall 3 and a second ring wall 4 arranged from the outside to the inside, the top of the first ring wall 3 is connected to the top of the second ring wall 4, and the second ring wall 4 extends from top to bottom in a stepped shape. The upper and lower distribution in this embodiment is based on the state when the metal casting handle for the compact shelving is placed horizontally, the direction from the turntable 1 to the handle 2 is the horizontal direction, and the radial direction of the turntable 1 is the vertical direction.

[0022] During the casting process, the thicker the wall thickness, the slower the cooling speed, and the greater the possibility of uneven internal structure. At the same time, the casting will shrink during the solidification process. The thicker the wall thickness, the greater the solidification shrinkage, which will cause uneven shrinkage inside and outside the casting and produce areas of stress concentration, thereby reducing the strength of the casting. Therefore, the design of the first annular wall 3 and the second annular wall 4 reduces the original large wall thickness, which is suitable for metal casting and forming, and adopts a double-layer design, and the overall structural strength is still high; the second annular wall 4 extends in a stepped manner from top to bottom, so that the second annular wall 4 is close to the center and can maintain uniform wall thickness.

[0023] In order to improve the strength, at least two first reinforcing plates 5 are provided between the first annular wall 3 and the second annular wall 4; the first reinforcing plates 5 are evenly distributed around the center; the top of the first reinforcing plate 5 extends to the top of the first annular wall 3, and the two sides of the first reinforcing plate 5 are respectively connected to the first annular wall 3 and the second annular wall 4; the bottom surface of the first reinforcing plate 5 is higher than the bottom surface of the first annular wall 3, and the bottom surface of the first reinforcing plate 5 is higher than the bottom surface of the second annular wall 4. The design of the first reinforcing plate 5 can improve the structural strength between the first annular wall 3 and the second annular wall 4. At the same time, during the casting process, the first reinforcing plate 5 can connect the first annular wall 3 and the second annular wall 4 to facilitate the flow of metal liquid during the casting process. The first reinforcing plates 5 are evenly distributed around the center to balance the structural strength and ensure that the metal liquid flows evenly during the casting process; the bottom surface of the first reinforcing plate 5 is high, which can reduce the metal material and reduce the weight, and the bottom surface of the first reinforcing plate 5 is not protruding and does not require further processing.

[0024] To increase the strength, Figure 3 As shown, the top of the first ring wall 3 is connected to the top of the second ring wall 4 through an inclined surface 6; the highest end of the inclined surface 6 is connected to the top of the first ring wall 3, and the lowest end of the inclined surface 6 is connected to the top of the second ring wall 4. The design of the inclined surface 6 can make the flow of the metal liquid more uniform during the casting process, and compared with the right-angle connection, the thickness of the connection is reduced, which helps to improve the strength.

[0025] For ease of processing, the bottom surface of the second annular wall 4 is higher than the bottom surface of the first annular wall 3.
