Abstract
The utility model discloses a positive-pressure air supply opening which consists of a shell, a panel door and an actuator, wherein a plurality of embedded bolts and tension spring type connecting pieces are arranged on the two sides inside the shell; the embedded bolts are fixedly arranged inside a mounting wall body by passing through embedded bolt holes formed in the two sides of the shell; the embedded bolts are arranged on the two sides of the upper part of the rear side of the panel door. By embedding the expansion bolts inside the shell of the positive-pressure air supply opening without using an electric tool, great convenience is provided for the installation work of an installer, the installation of the positive-pressure air supply opening can be independently implemented with only one operator, and during connection of the panel door and the shell, the installer can connect hooks of the tension spring type connecting pieces to the embedded bolts of the panel door so as to implement the installation of a fireproof door, so the positive-pressure air supply opening has the advantages of being simple in structure, convenient to install, time-saving and labor-saving.
Description
Technical field
The utility model relates to structural fire protection equipment technical field, is specifically related to a kind of forced draft mouth of being convenient to installation.
Background technology
Forced draft mouth is a kind of fire-fighting equipment that must install in urban architecture, conventionally be arranged on cup, elevator cup, share cup, staircase, normally off at ordinary times, during fire, fire signal is received at fire-fighting center, the forced draft mouth of opening conflagration area, starts to send new wind.Forced draft mouth is mainly comprised of housing and actuator, during installation, housing is embedded in body of wall, installation personnel need to switch on power wall drilling installation expansion bolt is fixed, and the panel door of hull outside also needs personnel to punch to be connected and fixed with housing, whole installation process wastes time and energy, need at least two installation personnel operations, cause installation cost high, installation effectiveness is also very low simultaneously.
Utility model content
The utility model provides a kind of forced draft mouth, to solve the loaded down with trivial details and low problem of installation effectiveness of installation that prior art exists.
The utility model is mainly comprised of housing, panel door and actuator, solving the technical scheme that its technical problem adopts is that enclosure interior both sides arrange some pre-embedded bolts and Extension Spring-type connector, pre-embedded bolt is fixed on and installs in body of wall through the pre-embedded bolt hole of housing both sides, and both sides, top arrange pre-embedded bolt after panel door.
Above-mentioned panel door top arranges access door, and hand hole is set on access door, and access door below arranges air hole.
Above-mentioned Extension Spring-type connector comprises the pedestal and the extension spring being connected with pedestal that is fixed on enclosure interior both sides, and the other end of extension spring, corresponding to the pre-embedded bolt on panel door, is connected with hook.
The utility model passes through at the pre-buried expansion bolt of forced draft mouth enclosure interior, needn't use electric tool simultaneously, greatly facilitate the installment work of installation personnel, only need the installation that operating personnel just can complete independently forced draft mouth, panel door is connected on the hook connecting of Extension Spring-type connector the installation that can complete fireproof door on the pre-embedded bolt of panel door with only needing installation personnel being connected of housing, has advantages of simple in structure, the easy for installation and less manpower that saves time.
