Description

Security door pick-proof structure

Technical field

The utility model belongs to the door lock assembly in the haberdashery and hardware series products.

Background technology

At present, four frames of widely used various security door doorframes and door leaf are torn open moldedly on the market by steel plate, and its rigidity is less; Although the lock that is provided with by the lock Synchronization Control in doorframe and door leaf junction directly is inserted between doorframe and the door leaf, but when the burglar is inserted into door leaf, the doorframe place of lockset dead bolt and lock keyed end with crowbar, be easy to make the distortion of doorframe and door leaf, cause the disengaging of the lock and the doorframe of dead bolt and circumferential arrangement, security door is pried open easily, has reduced theftproof performance.For this reason, some security door manufacturer takes to increase the lock way, and many persons even more than 20 lock arranged prize and steal time and the increase difficulty of forcing open the door in the hope of prolongation, but do not tackle the problem at its root yet, and complex structure, and cost improves.

Summary of the invention

The purpose of this utility model is exactly the problem at the pick-proof poor performance of existing various security doors existence, and design provides a kind of security door pick-proof structure, reaches the security door pick-proof ability that increases substantially, improves the purpose of safety.

Basic design of the present utility model is, security door circle inner edge is processed into notch doorframe Baltimore groove outwardly, on the inboard door face board of antitheft door leaf, be provided with notch door leaf Baltimore groove inwardly, doorframe Baltimore groove and door leaf Baltimore groove intersect the configuration that overlaps, be positioned at the doorframe Baltimore groove on the groove sidewall of door leaf Baltimore groove one side and be processed with the lock cylinder aperture that matches with lock, lock is inserted in the lock cylinder aperture, constitutes security door pick-proof structure.

The utility model is simple in structure, and is easily manufactured, with low cost, and the pick-proof ability is strong, and is safe and reliable.

The specific embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Security door pick-proof structure comprises anti-theft door frame 2, antitheft door leaf 3 and lock 1, anti-theft door frame 2 frame inner edges are processed into notch doorframe Baltimore groove 4 outwardly, on the inboard door face board of antitheft door leaf 3, be provided with notch door leaf Baltimore groove 5 inwardly, doorframe Baltimore groove 4 and door leaf Baltimore groove 5 intersect the configuration that overlaps, be positioned at doorframe Baltimore groove 4 on the groove sidewall of door leaf Baltimore groove 5 one sides and be processed with the lock cylinder aperture that matches with lock 1, lock 1 is inserted in the lock cylinder aperture.Different shapes such as the cross section of lock 1 can be rounded, rectangle, square, polygon, the lock cylinder aperture shape on its doorframe Baltimore groove 5, size and lock 1 are complementary.

When security door was shut, doorframe Baltimore groove 4 intersected to overlap with door leaf Baltimore groove 5 and cooperates, and forms pick-proof performance maze-type structure strongly, utilized in the lock cylinder aperture on door key driving lock 1 insertion two groove walls, and door lock is dead.When the burglar forces open the door,, dead bolt and anti-theft door frame 2 are broken away from, but because lock 1 still is inserted in two anti-pry notch, this door is not still opened even anti-theft door frame 2 and antitheft door leaf 3 produce distortion.
