Technical Field

The invention relates to the field of architectural decoration, in particular to a bolt capable of being installed quickly and tracelessly by utilizing magnetic force.

Background

In the existing commodity house, an entrance door is mostly provided with a safety door capable of preventing burglary and fire; in order to bring the furniture in and out conveniently, the safety door is made into a primary and secondary door, and becomes the standard of a plurality of commodity rooms.

The safety door is a complete door leaf formed by clamping fireproof materials between two metal stamping plates and then fixing the two metal stamping plates together. Security doors are often equipped with anti-theft locks, which are already equipped with anti-theft and internal counter-locking functions, and therefore security doors are usually no longer equipped with indoor bolts.

However, the theft with high technology can open and close the well-closed anti-theft lock by adopting a special method and a special key tool, and particularly after the coded lock is exposed by a video opened by an electronic master key, people always lift the inner container indoors with some care, so that the personal safety can not be guaranteed.

The best way to solve this problem is to add a bolt. However, the bolt is usually fixed by installing a screw on the door leaf, and the bolt is fixed by adopting a self-tapping screw when the bolt is installed on the iron sheet door.

Generally, an iron sheet on the indoor side of the safety door is thinner, the grasping degree of the self-tapping screw on the iron sheet is limited, and the self-tapping screw is easy to loosen and fall off when violent impact occurs; in the case of a renter's house, the homeowner usually does not intend to drill holes in the security door to install the door bolts, and the private installation of the renter may take the economic responsibility of door leaf restoration.
