Abstract
The utility model belongs to new wind devices accessory, specifically a kind of multi-functional lengthening section, including the upper half and lower half, and the upper half is equipped with internal screw thread, and outer surface is smooth surface, and the upper half is adapted to installation end in fresh air canyon；Lower half is equipped with external screw thread, inner surface is smooth surface, lower half is adapted to the outer connecting pin of fresh air canyon, this multi-functional lengthening section can individually take the upper half or lower half, it may also use as a whole, the problem of being used in duct length deficiency, can effectively solve wall pipe curtailment, influencing equipment installation.
Description
Technical field
This programme belongs to new blower technical field, and in particular to a kind of blast cap extension through walls.
Background technique
New blower is the air regenerating device that most of families use, and cabinet type new blower belongs to no duct type fresh air system, because
For it is compared to duct type fresh air system, project amount is small, does not destroy finishing.It only needs to open a through hole on common wall,
The ventilation duct and outdoor blast cap through walls of new blower are installed.Many families select new blower and breathing treasured to be applied in combination now,
They need to only open an aperture when installing on wall, be connected to new wind devices with outdoor by air hose, can will own in family
The air in room is quickly swapped with outdoor.
The precious structure of breathing is divided into two parts of indoor body and outdoor body.Two parts are connected by wall pipe.Production
Breathing it is precious when, the connecting tube of indoor section and outdoor section is produced by a full-length, therefore in actual installation
When connecting tube is mounted in wall hole frequent occurrence, length and the unmatched embarrassment of thickness of wall body.
Likewise, new assembling also often has similar installation question, new blower ventilation duct and setting are in wall hole
The blast cap in outside is connected, and usually the air hose of blast cap is fitted into wall hole, and air hose protrudes into indoor end and ventilation duct is solid
It connects, but the air hose of blast cap is also make by fixed metal tube in production, length and actual installation scene are also not necessarily
It can match.
Problem is mainly two kinds of situations: 1) wall has exceeded the precious script of breathing and sets since the factors such as interior decoration thicken
The connection length of tube of meter；2) new blower body shows installation site limitation, needs to be placed on from remote position in wall hole, ventilation
Length of tube is just insufficient to be connect with air hose.
The case where installation wall is greater than for connecting tube, as long as air hose, which is cut out a section, in the prior art can be solved, and such as
All factory parts of fruit all press overlength design, can waste lot of materials.When for connecting tube curtailment, in the prior art not yet
Very good solution method.
Utility model content
The utility model mainly solves duct length deficiency, and fresh air equipment indoor section and outdoor section is caused to can not be successfully
The problem of connecting together.
To solve this problem, the utility model provides a kind of extension, the specific scheme is that
A kind of multi-functional lengthening section, including the upper half and lower half, the upper half are equipped with internal screw thread, and outer surface is smooth surface, on
Half portion is adapted to installation end in fresh air canyon；Lower half is equipped with external screw thread, and inner surface is smooth surface, lower half and fresh air canyon
Outer connecting pin adaptation.
This multi-functional lengthening section can individually take the upper half or lower half, it is also possible to use as a whole, in air hose
The problem of being used when curtailment, can effectively solve wall pipe curtailment, influencing equipment installation.
Detailed description of the invention
Fig. 1 is this extension overall diagram；
Fig. 2 is this extension cross-sectional view；
Fig. 3 is this extension top view.
Specific embodiment
Extension provided by the utility model is exclusively used in the installation of blast cap outside cabinet type new blower room and the installation that breathing is precious, newly
The ventilation duct of blower, the air hose of the air hose for breathing precious indoor section and blast cap, the precious outdoor section air hose of breathing are typically all unified
Specification, so not need design too many for the caliber of the extension of the utility model, only selection standard caliber.
The structure of multi-functional lengthening section provided by the utility model specifically:
A kind of multi-functional lengthening section, including the upper half 1 and lower half 2, the upper half 1 are equipped with internal screw thread 3, and outer surface is light
Face, the upper half 1 are adapted to installation end in fresh air canyon；Lower half 2 is equipped with external screw thread 4, and inner surface is smooth surface, lower half 2 with
The outer connecting pin adaptation of fresh air canyon.
The utility model is attached to by installation personnel, is not fitted in the product of sale, if mounting portion when equipment is installed
Curtailment is selected to use, avoids waste of material to greatest extent by installation personnel.In use, this extension both can be under
Half portion 2 or the upper half 1 individually intercept use, can also be used as an entirety and use, application method multiplicity.
A) when being applied to cabinet type new assembling, when outdoor blast cap length is inadequate, can cooperate with outdoor blast cap makes
With the lower half portion of extension is intercepted, is screwed into outdoor blast cap air hose, extends air hose.
It b) is that wall is installed when breathing is precious when being applied to breathing Bao'an dress, when wall pipe curtailment, sanction goes this lengthening
One section for saving lower half portion, residue is suitably sized, then the internal screw thread of the top half of this extension and the precious outdoor of breathing
The external screw thread divided matches, and the external screw thread of lower half portion is matched with the internal screw thread for breathing precious indoor section.
This extension material is identical as wall-punching wind tube material.
1 outer surface of the upper half is equipped with two slots 5 parallel with in-between line.This extension is for adopting in extension wind
Pipe is manually tightened when installing, and the structure of the slot 5 can increase the frictional force of hand Yu extension surface, more in installation.
The utility model structure is simple, vdiverse in function, is selectively used according to installation situation, reusable, convenient for tearing open
It unloads, installation effect is beautiful, effectively solves the problems, such as wall pipe curtailment.
