Description

New-type anti-theft safety door

Technical field

The utility model relates to security door technical field, relates in particular to a kind of anti-theft safety door with multiple safety function.

Background technology

Security door is a kind of anti-theft device of being furnished with, and can resist unnormal unlocking under certain condition within a certain period of time, has certain security protection performance and meets other door of corresponding anti-theft security level, and it and people's the security of the lives and property is closely bound up.Along with the improvement of living standard and habitat condition, people require also more and more higher to the security performance of security door.

The security door of prior art is generally comprised of doorframe, door leaf, and security door front and back panels adopts Integral bending pressing to connect.As shown in Figure 1, be a kind of architectural feature of existing security door, wherein, 1 is doorframe, and 2 is door leaf, and 3 is dead bolt, relies on dead bolt 3 to realize the combination of door leaf 2 and doorframe 1, and this project organization is single, and theftproof performance is very weak.And around dead bolt 3, between door leaf 2 and doorframe 1, will inevitably leave gap, the sound insulation air-tightness that so just causes security door is not fine, affects people's normal dwelling environment.

Utility model content

Technical problem to be solved in the utility model is: a kind of new-type anti-theft safety door is provided, and it has multiple pick-proof device, can effectively improve the security performance of security door.

For solving the problems of the technologies described above, the technical solution of the utility model is: new-type anti-theft safety door, comprise doorframe and door leaf, and described doorframe edge is stepped, described doorframe is provided with a plurality of projections that are positioned at step edges place, between described projection and described corresponding ladder, forms groove; Described door leaf is provided with a plurality of projections corresponding with ladder.

As the improvement to technique scheme, on described door leaf, between two projections, be provided with airtight, in described doorframe groove bottom, be also provided with airtight.

Adopted after technique scheme; the beneficial effects of the utility model are: because doorframe edge is set to stepped; at step edges place, be provided with a plurality of projections; on door leaf, be provided with a plurality of projections corresponding with ladder simultaneously; can make like this to form between door leaf and doorframe a plurality of pick-proof obstacle nodes; protect layer by layer lock body, be not destroyed and pry open, effectively improve the security performance of security door.

Owing to being provided with airtight between two projections on door leaf, in doorframe groove bottom, be also provided with airtight simultaneously, can pass through so airtight and fill the space of doorframe between door leaf, greatly improve the sound insulation airtight effect of security door.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is the structural representation of prior art security door;

Fig. 2 is a kind of embodiment of the new-type anti-theft safety door of the utility model;

Wherein: 1-doorframe; 2-door leaf; 3-dead bolt; The antitheft node of 4-first; The antitheft node of 5-second; 6-the 3rd antitheft node; 7-projection; Airtight of 8-.

The specific embodiment

As shown in Figure 1, be the structural representation of a kind of security door of prior art, it is described in detail in background technology part, does not repeat them here.

As shown in Figure 2, a kind of embodiment for the new-type anti-theft safety door of the utility model, it comprises the stepped doorframe in edge 1, on doorframe 1, be provided with a plurality of projections that are positioned at step edges place, shown in figure is two, be respectively the 3rd antitheft node 6 and projection 7, and lay respectively at two step edges places bottom, between each protruding and corresponding ladder, all form groove.

On door leaf 2, be provided with a plurality of projections corresponding with ladder on doorframe 1, on door leaf 2, be also provided with two projections, be respectively the first antitheft node 4 and the second antitheft node 5.Like this, between doorframe 1 and door leaf 2, be equivalent to form triple anti-theft features, be respectively the first antitheft node 5 of antitheft node 4, second and the 3rd antitheft node 6, greatly improved the security performance of security door integral body.

In addition, between the first antitheft node 4 and the second antitheft node 5, be also provided with airtight 8, in doorframe 1 groove bottom, be also provided with airtight 8, by this structure, the gap between doorframe 1 and door leaf 2 can be filled as far as possible, improve the sound insulation airtight effect of security door.

Each node shown in figure, comprises that the first antitheft node 5 of antitheft node 4, second and the 3rd antitheft node 6 all make thickness and the intensity that steel plate Overlap design improves steel plate, strengthens anti-theft feature simultaneously.For example, original steel plate thickness is 1.2mm, and after Overlap design, steel plate thickness can reach 2.4mm, has greatly improved the anti-theft feature of security door.

Certainly, in Fig. 2 and the not shown dead bolt that plays latch functions, but its basic structure principle is known technology in the art, does not repeat them here.

New-type anti-theft safety door of the present utility model not only can improve the security performance of security door effectively, but also has increased the sound insulation airtight effect of security door, has good practicality.

The utility model is not limited to the above-mentioned specific embodiment, and all are based on technical conceive of the present utility model, and the structural improvement of having done, all falls among protection domain of the present utility model.
