Description
Technical field
This utility model relates to alarm technical field, is specifically related to a kind of explosion-proof alarm.
Background technology
In prior art, the structure of explosion-proof alarm is in enclosure interior perforate, by ventilative steel and alarm device from housing
Internal loading.There are the following problems for this installation method:
1, in housing, carry out perforate and add man-hour, for ensureing the installation reliability of ventilative steel, need to add from enclosure interior
Work, such cutter is with regard to bad entrance, and mould structure also cannot be accomplished, has accomplished mould structure the most at last also and complicated, cost
Of a relatively high.
2, ventilative steel and alarm device assemble in enclosure interior, because being to load from inside, three parts can be caused same
Heart degree deviation is excessive, causes the most concentric phenomenon to occur, simultaneously bonding agent also can uneven distribution, make alarm because defect occurs
And it is quick-fried to produce mistake, makes product not meet explosion-proof criteria, do not reach requirement of explosion proof.
Utility model content
The purpose of this utility model is, propose one processing, easy to assembly, cost-effective, and ensure assemble after product
The explosion-proof alarm of the explosion-proof performance of structure.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of explosion-proof alarm, including fixing lid, ventilative steel, housing and alarm device, described alarm device is arranged at shell
Internal portion, housing is provided with flame proof thread；Described fixing lid is hollow cylindrical, outer wall be provided with corresponding with housing every
Quick-fried screw thread；Described ventilative steel is cylindric, is arranged in fixing lid, the outer wall of ventilative steel and the contact internal walls of fixing lid, coordinates
Form cylinder type explosion suppresion surface.
It is provided with sealing gasket between the end of described ventilative steel and the end of fixing lid.
It is provided with sealing ring between described shell end and fixing lid.
It is provided with bonding agent between described alarm device and the inwall of housing.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
1, this utility model is by open-blind hole on housing, is first loaded in housing by alarm device, then equipped with ventilative steel
Fixing lid screw in housing, complete the installation of alarm.This programme simple in construction, processing, easy to assembly, processing cost is low,
And the explosion-proof performance of product is good after assembling.
2, sealing gasket and the setting of sealing ring, it is possible to of the present utility model sealing is effectively ensured, makes product more conform to
Explosive-proof grade.
3, bonding agent can effectively fix the position of alarm device, increases the stability of this programme.

Corresponding flame proof thread 8；Described ventilative steel 2 is cylindric, is arranged at fixing lid interior 5, the outer wall of ventilative steel 2 and fixing lid 5
Contact internal walls, cooperatively forms cylinder type explosion suppresion surface 9.
Embodiment 2
As a kind of preferred embodiment of the present utility model, with reference to Figure of description 1 to accompanying drawing 2, present embodiment discloses
A kind of explosion-proof alarm, the present embodiment includes:
A kind of explosion-proof alarm, including fixing lid 5, ventilative steel 2, housing 1 and alarm device 3, described alarm device 3 is arranged
Internal in housing 1, housing 1 is provided with flame proof thread；Described fixing lid 5 is hollow cylindrical, and outer wall is provided with and housing 1 phase
Corresponding flame proof thread 8；Described ventilative steel 2 is cylindric, is arranged at fixing lid interior 5, the outer wall of ventilative steel 2 and fixing lid 5
Contact internal walls, cooperatively forms cylinder type explosion suppresion surface 9.
It is provided with sealing gasket 4 between the end of described ventilative steel 2 and the end of fixing lid 5.
It is provided with sealing ring 6 between described housing 1 end and fixing lid 5.
It is provided with bonding agent 7 between described alarm device 3 and the inwall of housing 1.
Alarm device 3, by open-blind hole on housing 1, is first loaded in housing by this utility model, then equipped with ventilative steel 2
Fixing lid 5 screw in housing 1, complete the installation of alarm.This programme simple in construction, processing, easy to assembly, processing cost
Low, and after assembling, the explosion-proof performance of product is good.
Embodiment described above only have expressed the detailed description of the invention of the application, and it describes more concrete and detailed, but also
