Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of simple fire alarm of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
As shown in Figure 1, a kind of simple fire alarm, including cabinet 1,1 side of cabinet offer blow vent 2, case
Bottom support plate 3 is provided in body 1,3 top two sides of bottom support plate are connected with cavity 5 and upright bar 14 respectively, are provided in cavity 5
Thermal expansion layer 6, thermal expansion layer 6 are chosen as polythene material.Movable plate 7 is provided on thermal expansion layer 6, the lower end of fixed pin 4 is solid
It is scheduled in bottom support plate 3, fixed pin 4 sequentially passes through thermal expansion layer 6 and movable plate 7, and electric bell 16, electric bell are fixed in upright bar 14
It is provided with touching switch 15 on 16, the lower end of rotor plate 11 is articulated in bottom support plate 3,11 side of rotor plate is connected with elasticity
One end of rope 10, the other end of elastic string 10 are connected with lantern ring 9,9 sets of the lantern ring upper ends in fixed pin 4, the other side of rotor plate 11
It is connected with one end of spring 13, the other end of spring 13 is connected with upright bar 14.
The shape of cavity 5 is cylinder.
The material of cavity 5 is stainless steel.
7 side of movable plate is connected with protrusion 8, and the groove slided up and down for protrusion 8 is offered on the inside of cavity 5.
The shape of cabinet 1 is cuboid.
Rotor plate 11 is provided with cushion 12 close to the side of upright bar 14.
The working principle of the utility model are as follows: normal condition traps ring set in the upper end of fixed pin, and elastic string is to rotor plate
There is a pulling force to the left, spring is stretched at this time.When encountering fire, air themperature is heated very high, and thermal expansion layer can be swollen
It is swollen, drive movable plate to move upwards, lantern ring is squeezed out the upper end of fixed pin, at this time under the left and right of spring, rotor plate by movable part
On cushion contacted with the touching switch on electric bell, electric bell work, realize alarm.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
