Because the frame of the frame type cabinet is formed by assembling and welding the cold-formed steel with fixed length, the thickness of a material belt before cold-forming is not enough to punch a hole and tap the tooth on the material belt, and the fastening connection between the accessory and the frame can be realized only by matching the standard fastening screw and the reserved screw hole of the accessory arranged on the frame. Such an assembly connection is generally implemented in two ways: firstly, the frame is used as a boundary to be installed from inside to outside, and a screw passes through a modulus groove or a hole on the section steel to be connected with a reserved screw hole on an accessory; and the other is directly locked into the pre-punched hole on the frame by using a self-tapping screw. The first mode only supports the installation of the external hanging accessory from inside to outside at present, and in the second mode, the mode of fixing the cabinet accessory by the tapping screw can not bear the load and can not bear the complex load caused by factors such as impact vibration or elastic deformation, and the like, so that the defect is large.
