Beneficial effect
A kind of intelligent building fire alarm installation based on networking of the invention, when fiery residence occurs, staff is logical
Crossing pressing Fire Alarm Button mechanism makes fire alarm pedestal report fire signal outward, and concrete operations are as follows, to button cover
Plate force, so that the guide groove on button ontology drives pressing lever to stretch into hollow cylinder under the guide and limit effect of gib block,
Insulation board drives signal to touch passive normally opened output terminal displacement of the plate into fire alarm pedestal simultaneously, thus the 4th spring by
Original state is stretched, until the second card bead is passed through the second limit due to be resetted the power of offer by compression by the 5th spring
Hole, output contact constitutes closure signal at this time, to be sent out fire signal；Fire Alarm Button mechanism is resetted
When, it is exerted a force by the T-type pressing lever to both ends, so that T-type pressing lever forces in second spring, so that second spring is by original state quilt
Compression, so that T-type pressing lever drives the first spring, the first card bead, longitudinal spacing under the effect of the guide and limit of sliding block and sliding slot
Plate is mobile to the first limit hole direction, until the first card bead is not limited by shell and to be answered by the first spring due to being compressed
Position and the power provided is released while shifting in T-type pressing lever by traction rope so that the first card bead passes through the first limit hole
To the pulling force of interior bar, so that third spring is become smaller by the pressure of interior bar, the pressure to become smaller is third spring due to be answered by compression
Position provides power, so that interior bar is overhanging to outer cylinder, since the length of traction rope is fixed and nonelastic, therefore moved in T-type pressing lever
Distance is that the length that traction rope is released also is the overhanging distance of interior bar, extends to outside interior bar and provides pressure to the second card bead, so that
5th spring is compressed by pressure by original state, until the 4th spring is not by the second card bead when the second card bead is detached from the second limit hole
Limitation and due to be stretched to reset and drive insulation board, signal touch plate far from the normally opened output terminal in source, thus fire report
Alert button mechanism is resetted, and after reset, disengages it from the first limit hole to the first card bead force, and second spring due to
It to be resetted by compression and provide thrust to T-type pressing lever, so that T-type pressing lever generates pulling force to interior bar, so that interior bar is far from second
Limit hole, comprehensive and push-button reset power mechanism, push-button reset actuating mechanism are resetted, push-button reset power mechanism, button are multiple
When fiery residence can occur again for the operation that position actuating mechanism resets, the operation of Fire Alarm Button mechanism is not by the obstruction of interior bar；
Compared with prior art, the beneficial effects of the invention are as follows：Intelligent building fire alarm installation by dust cover body,
The combination setting of push-button reset power mechanism, push-button reset actuating mechanism, spring retainer group, Fire Alarm Button mechanism, without
Using using dedicated key, so that it may so that button is resetted, push-button reset can be carried out at the first time after fire, is resetted
Stablize, speed is fast, reduces the maintenance cost of fire alarm installation.

Pedestal 1 reports fire signal outward, and concrete operations are as follows, exerts a force to push button panel 2508, so that leading on button ontology 25081
It drives pressing lever 2509 to stretch into hollow cylinder 2507 under the guide and limit effect of gib block 2104 to slot 25082, insulate simultaneously
Plate 2502 drives signal to touch passive normally opened output terminal displacement of the plate 2501 into fire alarm pedestal 1, thus the 4th spring
2402 are stretched by original state, until the second card bead 2503 by the 5th spring 2505 due to by compression to reset offer power and
Across the second limit hole 2506, output contact constitutes closure signal at this time, to be sent out fire signal；It will be to fire alarm
When button mechanism 2 is resetted, exerted a force by the T-type pressing lever 2201 to both ends, so that T-type pressing lever 2201 forces in second
Spring 2207, so that second spring 2207 is compressed by original state, so that T-type pressing lever 2201 is in sliding block 2208 and sliding slot 2105
Guide and limit effect is lower to drive the first spring 2202, the first card bead 2203, longitudinal spacing plate 2204 to 2107 side of the first limit hole
To movement, until the first card bead 2203 not by shell 2101 limited and by the first spring 2202 due to being resetted by compression and
The power of offer passes through traction while shifting in T-type pressing lever 2201 so that the first card bead 2203 passes through the first limit hole 2107
Rope 2302 releases the pulling force to interior bar 2305, so that third spring 2303 is become smaller by the pressure of interior bar 2305, the pressure to become smaller
Power is provided due to be resetted by compression for third spring 2303, so that interior bar 2305 is overhanging to outer cylinder 2304, due to traction rope
2302 length is fixed and nonelastic, therefore the distance moved in T-type pressing lever 2201 is that the length that traction rope 2302 is released also is
The overhanging distance of interior bar 2305, interior bar 2305 extends to outside provides pressure to the second card bead 2503, so that the 5th spring 2505 is pressurized
Power is compressed by original state, until the 4th spring 2402 is not by the second card bead when the second card bead 2503 is detached from the second limit hole 2506
2503 limitation and due to be stretched to reset and drive insulation board 2502, signal touch plate 2501 far from the normally opened output end in source
Son after reset, disengages it from the first limit to the first card bead 2203 force so that Fire Alarm Button mechanism 25 is resetted
Position hole 2107, and second spring 2207 provides thrust to T-type pressing lever 2201 due to be resetted by compression, thus T-type pressing lever
2201 pairs of interior bars 2305 generate pulling force, so that interior bar 2305 is far from the second limit hole 2506, comprehensive and push-button reset power mechanism 22,
Push-button reset actuating mechanism 23 is resetted, the operation energy that push-button reset power mechanism 22, push-button reset actuating mechanism 23 reset
When enough fire residences of generation again, the operation of Fire Alarm Button mechanism 25 is not by the obstruction of interior bar.
The technological progress that the present invention obtains compared with the prior art is：Intelligent building fire alarm installation passes through dustproof cover sheet
The combination setting of body, push-button reset power mechanism, push-button reset actuating mechanism, spring retainer group, Fire Alarm Button mechanism, nothing
It must be using using dedicated key, so that it may so that button is resetted, push-button reset can be carried out at the first time after fire, it is multiple
Position is stablized, and speed is fast, reduces the maintenance cost of fire alarm installation.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
