Abstract
The utility model discloses an automatic flush bolt structure for a fire-proof door. The automatic flush bolt structure includes a flush bolt main body fixedly mounted on the second leaf of the fire-proof door. The automatic flush bolt structure also includes a resilient device fixed on the flush bolt main body, wherein the resilient device comprises a base and a bolt, the base and the bolt are connected via a spring, and the end of the bolt is of a slope shape. By adopting the above structure in the utility model, the automatic flush bolt structure for the fire-proof door can automatically lock the second leaf of the fire-proof door fast, thus preventing casualties and property losses caused by the spread of fire.
Description
Technical field
The utility model relates to a kind of labeled door Hardware fitting, especially relates to the automatic mortise bolt structure of a kind of labeled door.
Background technology
Along with the raising of people's awareness of the importance of fire prevention, labeled door has obtained increasing application in present building field.Present labeled door generally is to make door-plate by wooden or metal material, fills fire-proof heat-insulating material then in the middle of door-plate, thereby plays the effect of the slow intensity of a fire of inner heat insulation resistance.Under the situation of breaking out of fire, labeled door master fan is closed under the effect of door closer, and the mortise bolt up and down of secondary fan need be by manually opened and locking door leaf, in the urgent moment, the escape personnel will lock the fire prevention mortise bolt again after door closer shuts up the door carefully, realize biparting locking, do not meet the actual conditions of emergency escape, cause casualties easily and property loss.
The utility model content
The purpose of this utility model provides the automatic mortise bolt structure of a kind of labeled door, can automatic locking labeled door pair fan when fire takes place, and makes things convenient for the personnel escape, avoids causing casualties and property loss.
For achieving the above object, the utility model provides a kind of labeled door automatic mortise bolt structure, comprise the mortise bolt main body, described mortise bolt main body is fixedly mounted on the secondary fan of labeled door, the utility model also comprises the elastic device that is fixed on the described mortise bolt main body, described elastic device comprises base and dead bolt, connects by spring between described base and the described dead bolt, and the end of described dead bolt is inclined plane shape.
Preferably, be provided with lead between described base and the described dead bolt.
Preferably, also be provided with the latch hand push button on the described mortise bolt main body, described latch hand push button and described mortise bolt main body are structure as a whole.
Therefore, the utility model adopts the automatic mortise bolt structure of labeled door of said structure, can automatic locking labeled door pair fan when fire takes place, and makes things convenient for the personnel escape, avoids causing casualties and property loss.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings

Fig. 2 is the locking state structural representation of the automatic mortise bolt structure of the utility model labeled door embodiment.
The specific embodiment
Embodiment
Fig. 1 is the open mode structural representation of the automatic mortise bolt structure of the utility model labeled door embodiment, Fig. 2 is the locking state structural representation of the automatic mortise bolt structure of the utility model labeled door embodiment, the left side is the front view of present embodiment, the right side is the lateral view of present embodiment, as depicted in figs. 1 and 2, comprise mortise bolt main body 1, mortise bolt main body 1 is fixedly mounted on the secondary fan of labeled door, present embodiment also comprises the elastic device that is fixed on the mortise bolt main body 1, described elastic device comprises base 2 and dead bolt 3, connect by spring 4 between base 2 and the dead bolt 3, the end of dead bolt 3 is inclined plane shape.At labeled door when closing, labeled door master fan is closed automatically by door closer, when the secondary fan of manual-lock labeled door, because the end of dead bolt 3 is inclined plane shape, when dead bolt 3 contacts gradually with fireproof door frame, dead bolt 3 with the effect of the contact force of fireproof door frame under extrusion spring 4 gradually, enter the pin hole of reserving on the fireproof door frame fully until dead bolt 3, finishing mortise bolt main body 1 is that the elastic device on inclined-plane is plugged the process of the pin hole of reserving on the fireproof door frame automatically by end, thereby closes and lock the secondary fan of labeled door.
For preventing that dead bolt 3 from departing from orbit, be provided with lead 5 between base 2 and the dead bolt 3, dead bolt 3 fully along lead 5 operations, has guaranteed the reliability of present embodiment work in the process of extrusion spring 4.
Also be provided with latch hand push button 6 on the mortise bolt main body 1, latch hand push button 6 is structure as a whole with mortise bolt main body 1, when opening the secondary fan of labeled door, only need stir latch hand push button 6, dead bolt 3 is left in the pin hole of reserving on the fireproof door frame, and the stroke A of latch hand push button 6 is greater than the stroke B of dead bolt 3, to guarantee the reliability of present embodiment work.
Therefore, the utility model adopts the automatic mortise bolt structure of labeled door of said structure, can when taking place, fire avoid locking door leaf by labeled door mortise bolt about manually stirring again, only need the secondary fan of manual-lock labeled door, the labeled door mortise bolt can automatic locking labeled door pair be fanned, make things convenient for the personnel escape, avoid causing casualties and property loss.
It should be noted that at last: above embodiment is only in order to the technical solution of the utility model to be described but not limit it, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
