Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): referring to fig. 1-2, the present application provides a mounting hole of a security door, including a cylindrical side wall 112 and a bottom wall 111 formed by bending and extending inward from a terminal of the side wall 112, the side wall 112 and the bottom wall 111 together form a bore 11, an opening of the bore 11 is provided with a plugging port 12, the plugging port 12 includes a transition connection portion 121 formed by bending and extending outward from a head of the side wall 112, one side of the transition connection portion 121 far away from the cavity is provided with a surrounding portion 123, the transition connection portion 121 and the surrounding portion 123 are connected by an arc-shaped section 122 in a smooth transition manner, the surrounding portion 123 is provided with a plugging port opening 14, different from the existing mounting hole 1, a transverse cross section of the plugging port 12 is in a rectangular frame structure, that is, the whole is in a structure with an outer side and an inner circle, thereby reducing bending difficulty in processing of the transition connection portion and the surrounding portion.

The arc-shaped segment 122 is an arc segment, and the corresponding radius of the arc-shaped segment is 1-1.5mm, preferably 1.2mm, and the corresponding central angle of the arc-shaped segment is 90 °.

In addition, the bottom wall 111 is provided with a through hole 13 for fixing the door frame 3 by an expansion bolt; the mounting hole 1 and the doorframe 3 of the security door are made of the same material.

Referring to fig. 1, the present application further provides a plugging structure 2 applied to the mounting hole, which includes a plugging body 21 corresponding to the contour of the opening 14 of the plugging opening, a clamping connection portion 23 is bent from the peripheral edge of the plugging body 21 to one side thereof, the clamping connection portion 23 is fixed with the opening 14 of the plugging opening in an interference fit manner, and one end of the clamping connection portion 23, which is far away from the plugging body 21, is bent outward to extend to form a protrusion 22 for preventing the protrusion from coming off.
