Abstract

The utility model relates to a new prize-proof and sound insulating safety door, comprising a door leaf and a door frame. The utility model is characterized in that the end of the kink of the protecting edge extended from the outer side of the door leaf is 0-5mm away from the edge of the door leaf; the V-shaped groove is arranged opposite to the kink and on the door frame; a inner sound insulating strip is arranged on the inside surface of the edge of the door leaf, and an another outer sound insulating strip is arranged opposite to the inner edge of the door leaf and on the door frame. The utility model has the advantages of subtle conception, reasonable design, simple structure, high prize-proof and sound insulating performance, and higher safety, reliability and applicability, and with only a bender, the industrialized production of the utility model can be achieved.

Description

Novel pick-proof, sound insulation anti-theft safety door

One, technical field

The utility model relates to a kind of anti-theft safety door, is specifically related to improved steel anti-theft safety door with pick-proof, sound insulation function.

Two, background technology

Existing steel anti-theft safety door, aspect the pick-proof edge protection, generally the rim by steel security door outer surface position extends along the door leaf direction, blocks the slit between the Men Tiyu doorframe.This structure has certain pick-proof effect aspect pick-proof, but the robber can with door sled volume, thereby pry open the steel security door easily with between pry insertion (pouring) Men Bian and the doorframe.There is flanging its end, shutter limit of Chinese patent 99247949.5 disclosed " novel pick-proof shutter limit ", and the doorframe corresponding positions is equipped with the groove that cooperates with flanging.This structure improves to some extent than aforementioned techniques, but forms a supporting-point naturally owing to establish groove on the doorframe, and the robber still can insert pry between (pouring) Men Bian and the doorframe easily, with door sled volume, and the steel security door is pried open.And the groove on the doorframe also is not easy to processing.Aspect sound insulation, prior art all adopts single parting bead, has certain soundproof effect, but is subjected to the influence of the exposure level of size, door leaf and the doorframe of sound insulation bar and sound insulation bar, and the effect aspect sound insulation is many times unsatisfactory.

Three, summary of the invention

At the deficiency of above-mentioned prior art, the utility model provides a kind of novel pick-proof, sound insulation steel anti-theft safety door, and its technical scheme is as follows:

Novel pick-proof, sound insulation anti-theft safety door comprise door leaf and doorframe, it is characterized in that flanging end and doorframe limit that limit, door leaf outside extends to form edge protection differ 0-5mm, have " V " type groove with the corresponding doorframe of flanging position.The flanging end and doorframe limit of the edge protection that limit, door leaf outside extends to form preferably differ 0mm, promptly on a plane.

The angle of the flanging of described edge protection and door leaf outside is at 90 °～135 °.The angle of described " V " type groove is at 70 °～135 °.There is an inboard sound insulation bar sub-inboard, described door leaf limit, above the relative doorframe of door leaf inner edge another root outside sound insulation bar is arranged.

The utility model is skillfully constructed, reasonable in design, have simple in structure, as long as there is bending brake just can realize the industrialization operation.Its pick-proof, sound insulation effectively simultaneously has safety, reliability is higher, the characteristics that practicality is stronger.

Four, description of drawings

Fig. 1 is the utility model one embodiment structural representation.

Fig. 2 is the utility model second embodiment structural representation.

Five, the specific embodiment

Referring to Fig. 1, novel pick-proof, sound insulation anti-theft safety door comprise door leaf 1 and doorframe 5, and flanging 3 ends of the edge protection that limit, door leaf 1 outside extends to form and doorframe limit 6 have " V " type groove 7 with flanging 3 corresponding doorframe positions on a plane.The flanging 3 of edge protection is 90 ° with the angle of door leaf outside 2.The angle of " V " type groove is at 70 °.There is an inboard sound insulation bar 8 son 2 inboards in described door leaf limit, above the relative doorframe 5 of door leaf inner edge 4 another root outside sound insulation bar 9 are arranged.

See Fig. 2, the flanging 3 of edge protection is 135 ° with the angle of door leaf outside 2.The angle of " V " type groove is at 135 °.Other parts are with shown in Figure 1.

The utility model, because the sub-flanging 3 in door leaf outside is arranged above the door leaf of door leaf 1 outside 2, there is doorframe " V " type groove 7 at doorframe 5 corresponding positions, and doorframe limit 6 of door leaf flanging 3 outermost end in outside and doorframe 5 flushes, and promptly the end of the sub-flanging 3 in door leaf outside and doorframe limit 6 of doorframe 5 differ in 3 millimeters.So during sub-flanging 3, pry does not have supporting-point to the robber, even apply impact force on pry in the fan outside of forcing open the door with pry, pry inserts by force, owing on the doorframe 5 doorframe " V " type groove 7 is arranged, just in time allow the sub-flanging 3 in door leaf outside embed in doorframe " V " the type groove 7, form even at the cost of one's life or the locking shape.And the householder applies power at door leaf inner edge 4 positions to sub 2 directions in door leaf outside after opening door lock, and the steel security door can safe opening.Because there is an inboard sound insulation bar 8 sub 2 inboards, the interior outside of door leaf, an outside sound insulation bar 9 is arranged above the door leaf inner edge 4 corresponding doorframes 5 in addition, two dual sound insulations of sound insulation bar are promptly arranged.So the utlity model has superior pick-proof, sound insulation function.

Claims

1, novel pick-proof, sound insulation anti-theft safety door comprise door leaf and doorframe, it is characterized in that the flanging end and doorframe limit of the edge protection that limit, door leaf outside extends to form differs 0-5mm, with the corresponding doorframe of flanging position " V " type groove are arranged.
