The detector for fire alarm system structure of a kind of anti-battery neglected loading and slip-off preventing
Technical field
The utility model relates to fire alarm installation technical field, especially relates to a kind of detector for fire alarm system structure.
Background technology
Detector for fire alarm system is the physical quantity after fire is occurred, as temperature, smog etc. convert electric signal to, and a kind of automatic fire sniffer of reporting to the police to fire alarm control unit transmitted signal.In traditional detector for fire alarm system structure, when people install, often can forget assembling battery or in transportation, make mounted battery deviate from battery resettlement groove, cause whole detector to work, in the time that occurring, fire can not find in time dangerous situation.
Utility model content
The technical problems to be solved in the utility model is in order to overcome technological deficiency recited above, and the detector for fire alarm system structure of a kind of anti-battery neglected loading and slip-off preventing is provided.
In order to solve technical matters recited above, the utility model is taked following technical scheme:
The detector for fire alarm system structure of a kind of anti-battery neglected loading and slip-off preventing, include and coordinate upper cover and the lower cover installed, between upper cover and lower cover, there is the bearing for battery is installed, described bearing is placed in down and covers, on described bearing, be provided with battery resettlement groove, the periphery of described bearing offers post groove, described post groove is positioned at battery resettlement groove side, also include battery buckle device, described battery buckle device further includes the upper cover card handle that is designed to one, battery anticreep press strip and arrangement post, on described arrangement post, be provided with torsion spring, described arrangement post is placed in post groove, described battery anticreep press strip is placed in battery resettlement groove.
One end of described torsion spring is placed in post groove, and the other end of torsion spring acts on battery anticreep press strip.
The utility model is by setting up battery buckle device at battery resettlement groove side, in the time that battery is not installed, the effect of the torsion spring by battery buckle device, the outside that makes the upper cover card handle of battery buckle device expose lower cover, make upper cover can not coordinate installation with lower cover, play the effect of anti-battery neglected loading; Install after battery, the rotation of battery anticreep press strip is oppressed and driven to battery, and the upper cover card handle that drives battery buckle device rotates to lower cover inner side, make upper cover can coordinate smoothly installation with lower cover, simultaneously by the twisting force of torsion spring, make battery anticreep press strip push down the battery in battery resettlement groove always, effectively prevent the battery battery resettlement groove that comes off.
Detector for fire alarm system structure provided by the utility model, simple in structure, practical, can be widely used in various detector for fire alarm system.

Embodiment
See also Fig. 1 to Fig. 5, as shown in the figure, the detector for fire alarm system structure of a kind of anti-battery neglected loading and slip-off preventing, include and coordinate the upper cover 3 and lower cover 1 installed, between upper cover 3 and lower cover 1, there is the bearing 2 for battery is installed, bearing 2 is placed on lower cover 1, on bearing 2, be provided with battery resettlement groove 21, the periphery of bearing 2 offers post groove 22, post groove 22 is positioned at battery resettlement groove 21 sides, also include battery buckle device 4, battery buckle device 4 further includes the upper cover card handle 41 that is designed to one, battery anticreep press strip 42 and arrangement post 44, settle on post 44 and be provided with torsion spring 43, settle post 44 to be placed in post groove 22, battery anticreep press strip 42 is placed in battery resettlement groove 21.One end of torsion spring 43 is placed in post groove 22, and the other end of torsion spring 43 acts on battery anticreep press strip 42.
See also Fig. 3 and Fig. 5, as shown in the figure, in the time that battery is not installed, the effect of the torsion spring by battery buckle device, the outside that makes the upper cover card handle of battery buckle device expose lower cover, makes upper cover can not coordinate installation with lower cover, plays the effect of anti-battery neglected loading.
See also Fig. 1 and Fig. 4, as shown in the figure, install after battery, the rotation of battery anticreep press strip is oppressed and driven to battery, and the upper cover card handle that drives battery buckle device rotates to lower cover inner side, make upper cover can coordinate smoothly installation with lower cover, simultaneously by the twisting force of torsion spring, make battery anticreep press strip push down the battery in battery resettlement groove always, effectively prevent the battery battery resettlement groove that comes off.When unloading after battery, by the effect of torsion spring, upper cover card handle returns to again the state shown in Fig. 5.
