Description

A kind of reverse locking type security door

The utility model relates to the security door that is applicable to various buildings, specifically a kind of reverse locking type security door.

At present, the security door kind that provides on the market is a lot, have six select, eight select, coded electronic electric controlled door of the ten blinds windows of multiple spot locking door, luxurious plaque door, half-closed type such as selecting, canopy hurdle door, electric-controlled type, video intercom door or the like, although these functions are more, the style pattern is various, but all exists following weak point:

1, mechanical door lock on these or electric door lock all are the intraperitoneal that assembling is connected door leaf, the lock road is multidirectional up and down leading to, occupy and cut apart the door leaf intracavity space, make the layout of interior reinforcing rib design of door leaf and rigid member be subjected to very big restriction, can't realize desired desirable integral rigidity and intensity, simultaneously also can't be in door leaf filling winter protection fire proofing material uniformly, the winter protection fire-proof function also has been subjected to influence.

2, security door style, appearance and modeling and pattern all are that alteration of form and color change by door leaf realizes.Owing to the anti-lock in the door leaf and the lock road reason security door is restricted in style and shape-designing, especially the style of the semi-enclosed or open type security door that is adopted in the high temperature area designs, be subjected to unsurmountable restriction especially, made structure and style that some are desirable to realize.

The purpose of this utility model provides a kind of reverse locking type security door that can overcome above-mentioned weak point effectively, and it has good rigidly, intensity height, safe and reliable, can not be subjected to door lock restriction and is designed to the advantage of various styles.

To achieve these goals, technical design core of the present utility model is; Change the traditional structure that door lock in the past is assembled in door leaf intraperitoneal door lock frame, door lock is assembled in locks door leaf in the doorframe, eliminate obstacle and restriction that door lock causes,, develop the style and the pattern of security door to greatest extent with this integral rigidity and intensity of improving security door.Its technical essential is:

A kind of reverse locking type security door, it comprises door leaf, safe-guard door lock, hinge, it is characterized in that: linkage from top to bottom lock and safe-guard door lock are assembled in the doorframe, its tapered end is corresponding with lock box up and down and limit lock box on the door leaf respectively with dead bolt, long locking bar and the phase-locked moving limit of security door in the linkage from top to bottom lock, cross bar fulcrum shaft and tapered end support are connected with upper and lower frames in the doorframe.

Above-mentioned security door is characterized in that doorframe is to be made of lock frame, upper and lower frames, hinge frame, and each frame all is to be by two cross sections Preceding half frame of shape and the minor face overlaid of later half frame are composed of a fixed connection.

Above-mentioned security door, it is characterized in that linkage from top to bottom lock is made up of long locking bar, bearing pin, cross locking bar, cross bar fulcrum shaft, tapered end support, tapered end axle, tapered end, cross locking bar one end by bearing pin and long locking bar mutually axle connect, the other end connects with the tapered end axle is moving mutually, the tapered end axle is fixed on and is positioned on the tapered end that the tapered end support can slide up and down, and the cross bar fulcrum shaft is connected with cross locking bar axle.

The utility model has the advantages that:

1, doorframe is to adopt the two parts of half frame to welding combined, and intensity is good, indeformable, can assemble the automatically controlled product of all kinds of mechanical locks and electronic lock or other in the frame.Because door lock is assembled in the doorframe, alleviated the rotating load of door leaf, the door leaf inner-cavity structure can unrestricted reasonable Arrangement, and the coldproof material filling of preventing fires simultaneously is full, and fireproof heat insulating is good, linkage from top to bottom.Lock construction is reasonable, compact, the transmission sensitivity is connected combination with commercially available safe-guard door lock, the locking of multiple spot interlock, open and close synchronously, performance is safe and reliable, and doorframe door leaf integral rigidity is good, the intensity height, indeformable, shock resistance will be higher than door leaf by related standards regulation doorframe with the material standard simultaneously, so the anti-theft security performance of door lock further significantly improves.

2, can maximally utilise the space of door leaf, be designed to the security door of various styles and style, make the utility model both have the safety and reliability of security door, can fully show the colourful of modern door again.

The utility model has the following drawings:

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is that linkage from top to bottom lock and safe-guard door lock are assembled in structural representation in the doorframe among Fig. 1.

Fig. 3 is the left view of Fig. 2.

Fig. 4 is the vertical view of Fig. 2.

Fig. 5 is the cross-sectional structure schematic diagram that Fig. 2 lays down doorframe behind linkage from top to bottom lock and the safe-guard door lock.

The utility model is described in further detail below in conjunction with accompanying drawing.Shown in Fig. 1-5, door leaf 3 is hinged with doorframe 1 mutually by hinge 5.Doorframe 1 is to be made of lock frame 1A, upper and lower frames 1B, hinge frame 1C, and each frame all is to be by two cross sections
