the waist-shaped hole comprises two screw holes, a baffle groove and an elastic baffle, the baffle groove is positioned between the two screw holes, the elastic baffle is arranged in the baffle groove, the bottom surface of the elastic baffle is connected with the waist-shaped hole and is integrally formed, two ends of the top surface of the elastic baffle are respectively provided with a stop block, and when the elastic baffle is in a stable state, the two stop blocks are positioned above the corresponding locking screws.
Furthermore, a gap is arranged between the elastic baffle and the blocking groove.
Furthermore, the distance between the elastic baffle and the edge of the adjacent screw hole is 2-3 mm.
Further, the number of the kidney-shaped holes is 8 or 16.
Furthermore, the stop block is positioned 1-8mm above the corresponding locking screw in a natural state of the elastic baffle.
A method for disassembling a detachable anti-drop terminal button box comprises the following steps:
loosening locking screw and binding post, applying the power of vertical direction to elastic baffle, elastic baffle warp and makes the dog of application of force direction avoid corresponding side locking screw's top, locking screw can the roll-off screw hole.
The invention has the beneficial effects that:
the box body and the plurality of locking screws have the effects of preventing the locking screws from falling off and normally disassembling the locking screws through the limit of the stop blocks and the deformation of the elastic baffle plates.
When the elastic baffle plate is installed, the elastic baffle plate and the baffle groove play a role of deformation but no fracture, thereby reducing the repair in the production process and the maintenance cost of the product after operation, realizing the assembly and maintenance of the product and reducing the comprehensive cost of the instrument.
Additional features and advantages of the invention will be set forth in the detailed description which follows.
