Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 1 to 3. Control panel with turn-up structure, including shell 1 and base plate 2, the cladding of shell 1 is in the base plate 2 outside, and the shape of base plate 2 is unanimous with the shape of shell 1, and the upper and lower both sides of base plate 2 are equipped with first hem 21 and second hem respectively, and the left and right sides of base plate is equipped with the third hem and turns over the hem with the fourth respectively. When the base plate is turned over to the left side and the right side, the third turning edge and the fourth turning edge are positioned on the left side and the right side of the shell 1, so that the plane of the base plate 2, two faces which are turned over and stretched upwards or downwards and two sides which are wrapped on the two sides after stretching are achieved, the total five faces are visible faces, and the use requirements of the existing control panel are met through the reverse wrapping of the base plate 2.

The substrate 2 is made of a sheet 3 through molding, the upper side and the lower side of the sheet 3 are both provided with first hanging lugs 31, and the two top points below the sheet 3 are both provided with second hanging lugs 32. The first hanging lugs 31 can be a plurality of, three, four, five or six or more, and are uniformly distributed according to the length of the sheet 3, so that when the sheet 3 is folded and stretched, external force can act on the first hanging lugs 31 to stretch the sheet 3 outwards. In order to facilitate the action of external force, the first hanging lug 31 is provided with a through hole, so that the first hanging lug can be hooked on the through hole when the external force is stretched. In the actual use process, the top edge of the sheet 3 is turned smoothly, and the flat turning and stretching can be realized through the first hanging lug 31, so that hanging lugs do not need to be arranged at two top points of the top edge; since the lower folded angle of the sheet 3 is large, the second hanging lug 32 is provided to avoid the occurrence of wrinkles at the lower vertex.

The second hanging lug 32 comprises a body 33, a through hole 34 is formed in the middle of the body 33, a first inclined edge 39 and a second inclined edge 35 are arranged on two sides of the body 33 respectively, one end of the first inclined edge 39 is connected with one end of the second inclined edge 35 through an arc-shaped edge 36, and the radius of the arc-shaped edge 36 is 6 mm. Through-hole 32, external corresponding structure can be used in through-hole 32, stretches body 31 to realized the tensile to sheet 3 apex, prevented that the below of sheet 3 from turning over when rolling over in the tensile, the material from piling up, prevented the fold phenomenon from appearing.

The other end of the first inclined edge 39 is connected to the bottom edge of the sheet by a first arc-shaped portion 37, the other end of the second inclined edge 35 is connected to the side edge of the sheet by a second arc-shaped portion 38, the radius of the first arc-shaped portion 37 is 1mm, and the radius of the second arc-shaped portion 38 is 0.5 mm.
