Property.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of self-locking dress of the fire resistant doorsets for cell interior architecture
Set, this self-locking device can be used in the self-locking operation of cell fire resistant doorsets, in the normal state fire resistant doorsets self-locking device effect under,
In normally off, only under manual operation, can just open, and then ensure that safety.
In order to realize above-mentioned technical characteristic, purpose of the utility model is realized as follows: a kind of in cell room
The fire prevention door self-locking device of building, it includes mounting base, and the mounting base is fixedly mounted on fire prevention gate flap, at installation bottom
It is fixed on plate on rectangle fixed block described in rectangle fixed block and locking hook plate, one end of the locking hook plate is hinged with by shaft
It is provided with gib head, the gib head is matched with U-shaped hook, and is hooked to it；The U-shaped hook is fixedly mounted on gusset, institute
State and be machined with through-hole far from the side of gib head on locking hook plate, the through-hole is connected with spring tensioning means, and make gib head with it is U-shaped
Hook hooks cooperation.
The gusset is fixedly mounted on the doorframe of fire resistant doorsets.
Operation post is fixedly installed at the top of the locking hook plate.
The spring tensioning means include tension spring, and one end of the tension spring is mutually hooked with through-hole, and the other end passes through fixed spiral shell
Mother's fixation is hooked on column, and the column is vertically installed on mounting base.
The gusset is bolted on doorframe.
The utility model has the advantages that:
1, by the fire prevention door self-locking device, it can be used in the self-locking of fire resistant doorsets, in general, fire resistant doorsets are
For closing self-locking state, the self-locking device of above structure, during the work time, under the pulling force effect of tension spring, so that locking
Gib head is caught on U-shaped hook always by hook plate, and then ensure that the gate flap of fire resistant doorsets is in close state always.
2, locking hook plate can be operated by the operation post, and then unlocked under the action of manually,
Fire resistant doorsets can be opened at this time.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the first visual angle of the utility model overall structure diagram.
Fig. 2 is the second visual angle of the utility model overall structure diagram.
Fig. 3 is the utility model third visual angle overall structure diagram.
In figure: mounting base 1, column 2, fixture nut 3, tension spring 4, shaft 5, locking hook plate 6, operation post 7, gusset 8, spiral shell
Bolt 9, U-shaped hook 10, gib head 11, rectangle fixed block 12, through-hole 13.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Referring to Fig. 1-3, a kind of fire prevention door self-locking device for cell interior architecture, it includes mounting base 1, the peace
Dress bottom plate 1 is fixedly mounted on fire prevention gate flap, is fixed on rectangle fixed block 12 described in rectangle fixed block 12 on mounting base 1
It is hinged with locking hook plate 6 by shaft 5, one end of the locking hook plate 6 is provided with gib head 11, the gib head 11 and U-shaped hook 10
It matches, and it is hooked；The U-shaped hook 10 is fixedly mounted on gusset 8, far from gib head 11 on the locking hook plate 6
Side be machined with through-hole 13, the through-hole 13 is connected with spring tensioning means, and hooks gib head 11 and U-shaped hook 10 and cooperate.
It can guarantee that fire resistant doorsets are in self-locking closed state always by using above-mentioned fire prevention door self-locking device, and then meet its use
It is required that.
Further, the gusset 8 is fixedly mounted on the doorframe of fire resistant doorsets.Installation process is facilitated by gusset 8.
Further, the top of the locking hook plate 6 is fixedly installed with operation post 7.It being capable of hand by the operation post 7
Dynamic operation locking hook plate 6 releases self-locking state in turn, facilitates unlatching gate flap.
Further, the spring tensioning means include tension spring 4, and one end and 13 phase of through-hole of the tension spring 4 hook, another
End is hooked on column 2 by the fixation of fixture nut 3, and the column 2 is vertically installed on mounting base 1.Under usual condition, institute
