Abstract
The invention discloses an anti-theft unequal double leaf door. The anti-theft unequal double leaf door comprises a first door leaf and a second door leaf. A door lock is arranged in the middle of the matching face of the first door leaf, and a lock position is arranged on the matching face of the second door leaf. An anti-pry folded edge is arranged on the outer lateral side of the matching face of the first door leaf, an anti-pry concave position is arranged on the outer lateral face of the second door leaf, and an anti-pry convex edge capable of being clamped to the anti-pry folded edge is arranged in the position, close to one side of the first door leaf, of the anti-pry concave position. The anti-theft unequal double leaf door is ingenious and reasonable in structural design; after the door is closed, the anti-pry folded edge and the anti-pry convex edge are buckled with each other and can restrict each other so that an anti-pry structure can be formed, a pry bar cannot directly enter a door crevice to damage the door lock, meanwhile, the force applying direction of the pry bar is also limited, so that the force applying direction of the pry bar and the door crevice are not located in the same straight line, and thus damage to the door lock is eradicated. The safety performance is greatly promoted, and the anti-theft unequal double leaf door is high in overall structural strength, good in anti-theft effect, simple and compact in overall structure, easy to machine and manufacture, low in cost, attractive and elegant in appearance and favorable for wide population and application.
