Abstract

A ventilating anti-theft door comprises an outer door board and an inner door board which are provided with a plurality of lines of ventilating holes on the surface, between which an empty cavity is arranged. The empty cavity is provide with a movable sheltering board provided with a deflector rod next to the outer door board in the empty cavity, while the surface is provided with a plurality of lines of ventilating holes and a transverse through groove. A fixed bracket is arranged between the outer door board and the inner door board, between which a rolling pin is arranged in the transverse through groove to match and form a ventilating opening and closing mechanism. The utility model has the advantaged of compact structure, easy installation and production, fine anti-theft, fine ventilating, and convenient use.

Description

Ventilative security door

Technical field: the utility model relates to a kind of security door.

Background technology: general security door is closed, in order to increase gas permeability, can adopt paling form, but influence safety.Some adopts paling form to add the composite construction that seals wicket, but complex structure is produced the installation trouble, and use is inconvenient, and effect is undesirable.

Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of compact conformation, not only antitheft but also ventilative security door.

The utility model comprises that the surface all has the external door panel and the internal hilar plate of many row's air-vents, cavity is arranged between the two, in cavity, be equipped with the mobile shield of band driving lever near the external door panel place, the surface is also corresponding to have many row's air-vents and is provided with horizontal groove, and the roller bolt that fixed mount is located between external door panel and the internal hilar plate places horizontal groove to cooperate formation air-vent switching mechanism.

During use, the pulling driving lever, mobile shield is traversing under the cooperation of laterally groove and roller bolt, the air-vent on the mobile like this shield just and the air-vent on the inside and outside door-plate overlap or stagger, make the ventilative or sealing of security door.The utility model compact conformation is produced and installed easily, and is not only antitheft but also ventilative, easy to use, effective.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the front view of embodiment;

Fig. 2 is the front view of mobile shield;

Fig. 3 is that the A-A of Fig. 1 analyses and observe enlarged diagram;

Fig. 4 is that the B of jump ring and driving lever among Fig. 3 is to view.

Embodiment: as shown in the figure, external door panel 2 and internal hilar plate 1 surface all have many row's air-vents 6, be equipped with the mobile shield 3 of band driving lever 5 in the cavity 4 between external door panel 2 and internal hilar plate 1, these mobile shield 3 parallel close external door panel 2, the surface is also corresponding to have many row's air-vents 6 and is provided with horizontal groove 7, and the roller bolt 8 that fixed mount is located between external door panel 2 and the internal hilar plate 1 places horizontal groove 7 to cooperate formation air-vent switching mechanism.Present embodiment is with guide and limit cover 10 outside roller bolt 8, can guarantee that mobile shield 3 correct guiding do not rock, and moves more steady.Also can be connected with jump ring 9 on internal hilar plate 1, the driving lever 5 of mobile shield 3 and its cooperate formation chucking position-limit mechanism, and it is mobile to prevent that mobile shield 3 from being bumped by the external force mistake, improves safety.In practice, the air-vent 6 on the door-plate generally is arranged to two parts up and down, and mobile shield 3 can open and close respectively accordingly with two.
