Description

A kind of board-like security door

The utility model belongs to a kind of security door.

At present, the condition of public security is relatively poor, original paling form irony security door has been difficult to play its due antitheft effect, and old friends tend to install board-like security door one after another, and the board-like security door theftproof performance of selling on the market is better at present, but complex structure, its needs at least two cover locksets are controlled locking bolt separately, thereby use inconvenience, and manufacturing cost is also higher, particularly bad if the burglar turns round at the outdoor handle that will drive additional locking bolt, then owner also can't enter.

The purpose of this utility model is that existing board-like security door is improved, and designs a kind of general need one cover lockset, controls additional locking bolt simultaneously by this lockset, in the hope of reducing cost, simplifies open the door formality, particularly burglar and is difficult to board-like security door that lockset is destroyed.

Major technique measure of the present utility model is as follows:
