Description
Technical field
The utility model belongs to technical field of air purification, specifically a kind of extension wall construction for fresh air system.
Background technique
Fresh air system is according in closed indoor side sending fresh air to interior with special equipment, then from the other side by dedicated
Equipment will form " fresh air field of flow " to outdoor discharge indoors, to meet the needs of indoor fresh air ventilating.Embodiment
Be: using high wind pressure, big flow blower, by mechanical strength from a side to indoor air-supply, by the other side with the row specially designed
Wind blower forces the formation fresh air field of flow in system to the mode of outdoor discharge.Currently, host installation is both needed to backboard spiral shell
Silk is fixed, thus needs that backboard is separately configured, not only increases the difficulty of installation, while increasing cost.
Utility model content
In order to make up for the deficiencies of the prior art, the utility model proposes a kind of extension wall construction for fresh air system.This
Invention is inconvenient for solving the problems, such as host installation.
The technical scheme adopted by the utility model to solve the technical problem is as follows: described in the utility model a kind of for new
The extension wall construction of wind system, including host, the host back are provided with threaded hole, host by threaded hole with it is swollen on wall
Swollen screw is connected, and realizes the installation of host.When needing to install, expanding screw that three holes at host back are directly hung on a wall
On silk, cost is saved, it is easy for installation.
The host is provided with boss in the position of threaded hole.In the Position Design boss of host upper screwed hole, increase
Bonding strength between host and swell fixture ensure that the safety and reliability of host installation.
Reinforcing rib is provided on the inside of the host back.The presence of reinforcing rib further increases the whole knot inside host
Structure intensity ensure that the safety of connection.
The beneficial effects of the utility model are as follows:
1. a kind of extension wall construction for fresh air system described in the utility model will when the utility model needs to install
On the setscrew that three holes at host back are directly hung on a wall, cost is saved, it is easy for installation.
2. a kind of extension wall construction for fresh air system described in the utility model, the utility model pass through the spiral shell on host
The Position Design boss of pit, increases the bonding strength between host and swell fixture, ensure that the safety of host installation
And reliability.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the main view of the utility model；
In figure: host 1, threaded hole 11.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines specific embodiment, and the utility model is further described.
As shown in Figure 1, a kind of extension wall construction for fresh air system, including host 1,1 back of host are provided with spiral shell
Pit 11, host 1 are connected by threaded hole 11 with the swell fixture on wall, realize the installation of host 1.When needing to install,
On the setscrew that three holes at 1 back of host are directly hung on a wall, cost is saved, it is easy for installation.
The host 1 is provided with boss in the position of threaded hole 11.In the Position Design boss of 1 upper screwed hole 11 of host,
The bonding strength between host 1 and swell fixture is increased, ensure that the safety and reliability that host 1 is installed.
Reinforcing rib is provided on the inside of 1 back of host.The presence of reinforcing rib further increases the entirety inside host 1
Structural strength ensure that the safety of connection.
