Description
The utility model relates to a kind of improvement invention of steel security door front and back panel syndeton.
In the prior art, front and back panels in reveal in butt joint, middle adopt spot welding, in order to protect outward appearance, reveal pastes a strip of paper used for sealing again and prevents that weld seam from exposing.Another kind of situation be front and back panels in reveal in butt joint, a steel plate is pasted on the reveal limit, adopts screw or rivet to connect, its shortcoming is that manufacture craft is loaded down with trivial details, profile is not attractive in appearance, the while is time-consuming, the cost of production height.
At the problem that prior art exists, the utility model aims to provide a kind of steel security door front and back panels bridging arrangement, realizes the simple purpose of security door manufacture craft.
The utility model is finished as follows, comprise front panel, fixedly inner frame, rear board, described front and back panel connected mode is a bridging arrangement, the edge of described front panel is provided with an elongated slot, its cross section is the back-shaped shape of opening, the edge of described rear board is a right angle type, and a right-angle side embeds in the elongated slot, and the security door overlapping part is left and right, last three positions.
The steel security door front and back panels bridging arrangement of the utility model theme design, manufacture craft is simple, has reduced cost of production.Simultaneously, the edge of protrusion can block crack between a door and its frame and doubt, and lock is had certain pick-proof effect.
The utility model has following accompanying drawing
Fig. 1 is a cross-sectional view of the present utility model
Accompanying drawing has been represented structure of the present utility model, further describe embodiment below more in conjunction with the accompanying drawings: comprise front panel (1), fixedly inner frame (2), rear board (3), described front and back panels connected mode is a bridging arrangement, the edge of described front panel (1) is provided with an elongated slot (4), its cross section is the back-shaped shape of well head, the edge of described rear board (3) is a right angle type, one right-angle side embeds elongated slot (4) lining, normally left and right, last three positions of security door overlapping part guarantee its firmness.Its annexation can once be suppressed and be formed, and omits many technologies, and the edge of protrusion can block the slit between doorframe and the door, prevents that stealer from destroying dead bolt in crack between a door and its frame.
