In other words, the steel frame is separated from the switch main body after installation deformation, and the stroke of the switch button is not affected.

Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of assembly structure of switch steel frame. BACKGROUND

[0002] The existing steel frame, face frame, key panel are composed of. Traditional switch structure, screw hole installation deformation warp deformation occurs on both sides of steel frame, lead to the face frame assembled with it warp deformation. So as to lead to the stroke of button becomes small, lead to switch feel change or switch failure. SUMMARY

[0003] The utility model aims at providing a kind of assembly structure of switch steel frame of optimization button stroke.

[0004] The above object is realized as follows.

[0005] A kind of assembly structure of switch steel frame, including face frame, steel frame, the steel frame is arranged in face frame back, the face frame back is equipped with installation platform, and the lower end of installation platform is equipped with sink cavity, when steel frame is installed on installation platform, there is gap between the lower end of steel frame and sink cavity.

[0006] The purpose of the utility model can also be optimized using the following technical measures.

[0007] Preferably, the left and right sides of the installation platform are provided with accommodating grooves, the left and right sides of the steel frame are provided with supporting pieces corresponding to the accommodating grooves, and when the steel frame is installed on the installation platform, the supporting pieces are embedded in the accommodating grooves and contact the bottom surfaces of the accommodating grooves.

[0008] Further, the depth of the accommodating groove is consistent with the depth of the sink cavity.

[0009] Preferably, a buckle ear is arranged on the frame at the sink cavity, a buckle groove is arranged on the steel frame corresponding to the buckle ear, and when the steel frame is installed on the installation platform, the buckle ear engages the buckle groove.

[0010] Further, the buckle groove is a convex edge protruding towards the sink cavity, and when the steel frame is installed on the installation platform, the buckle groove contacts the surface of the sink cavity.

[0011] After adopting the above technical scheme, the utility model optimizes the assembly gap in the height direction between the face frame and the two sides of the steel frame, so that when the steel frame is deformed, the face frame will not warp and deform. It ensures that the stroke of the button will not change. It ensures the switch feel and performance, that is, the steel frame is separated from the switch body after deformation, and will not affect the stroke of the switch button.

[0019] The utility model will be further described below in combination with the drawings and specific embodiments.

[0020] In combination with Figures 1-2 , the assembly structure of the switch steel frame comprises a face frame 1 and a steel frame 2, the steel frame 2 is arranged at the back of the face frame 1, the back of the face frame 1 is provided with a mounting platform 11, the lower and upper ends of the mounting platform 11 are provided with sunken cavities 12, in combination with Figure 7 , when the steel frame 2 is installed on the mounting platform 11, there is a gap 3 between the lower and upper ends of the steel frame 2 and the sunken cavities 12, wherein the gap 3 is caused by the height difference between the sunken cavities 12 and the mounting platform 11.

[0021] In combination with Figure 3 and Figure 4 , the left and right sides of the mounting platform 11 are provided with accommodating grooves 13, the left and right sides of the steel frame 2 are provided with supporting pieces 21 corresponding to the accommodating grooves 13, when the steel frame 2 is installed on the mounting platform 11, the supporting pieces 21 are embedded in the accommodating grooves 13 and contact the bottom surfaces of the accommodating grooves 13, and the supporting pieces 21 support the steel frame 2, and the mounting platform 11 also supports the steel frame 2, and further, the depth of the accommodating grooves 13 is consistent with the depth of the sunken cavities 12.

[0022] In combination with Figures 3-5 , the edge frame at the sunken cavities 12 is provided with a buckling lug 14, the steel frame 2 is provided with a buckling groove 22 corresponding to the position of the buckling lug 14, when the steel frame 2 is installed on the mounting platform 11, the buckling lug 14 engages the buckling groove 22 and limits the steel frame 2, so that the steel frame 2 cannot be separated from the mounting platform 11. The buckling groove 22 is a convex edge of the steel frame 2 stamped in the direction of the sunken cavities 12, the shape of the convex edge is similar to a trapezoid, when the steel frame 2 is installed on the mounting platform 11, the buckling groove 22 contacts the surface of the sunken cavities 12 and provides a supporting action on the steel frame 2.
