Abstract
The utility model relates to the technical field of ventilation ducts, in particular to an assembling type ventilation duct part suitable for a central air conditioner and a ventilation system of a laboratory. A quick-mounted insertion type ventilation duct is of a cylinder structure formed by inserting foam plastic plates through connector clips and fasteners, the connector clips are respectively arranged at the connection positions of the adjacent foam plastic plates, and the connector clips are in insertion matched with two longitudinal edges of the adjacent foam plastic plates through two grooves arranged on the connector clips. The fasteners are arranged at the end ports of the ventilation duct and comprise hoop parts with the cross-shaped sections, the hoop parts are respectively installed on the horizontal edges of the foam plastic plates, and hoop parts respectively abut against corresponding foam plastic plates through connectors at the included angle positions of the adjacent foam plastic plates. The quick-mounted insertion type ventilation duct is light in weight, small in size, good in thermal insulation and noise elimination performance, convenient to install and transport and widely applied to the central air conditioners and the ventilation systems of the laboratories.
Description
Technical field
The utility model relates to the ventilation duct technical field, is specifically related to a kind of fast-assembling plug-in type ventilation duct that is applicable to central air-conditioner and laboratory ventilation system.
Background technique
Central air-conditioning system and the common airduct of laboratory ventilation system mainly adopt PP material, pvc material and glass steel material at present, above-mentioned several types airduct Heavy Weight, insulation and acoustic attenuation performance are poor, therefore in the process that airduct is installed, also to install separately silencing apparatus and thermal insulation layer additional, waste time and energy, and increased installation cost.In addition, at present existing ventilation duct has plenty of by the binding agent moulding, also have plenty of by the assembly unit straight forming, but existing a lot of airduct assembly unit step is complicated, waste time and energy, sometimes also will be by special tool, so this type of airduct is normally transported to the scene after the assembly unit well in factory, but the airduct after the moulding is not easy to transportation because weight is large, volume is large very much.
The model utility content
The purpose of this utility model is the defective for existing airduct, and a kind of lightweight, insulation and acoustic attenuation performance fast-assembling plug-in type ventilation duct good and easy for installation are provided.
The utility model adopts the manufacturer's standard part, then forms ventilation duct by on-site consolidation, specifically is achieved through the following technical solutions: fast-assembling plug-in type ventilation duct is pegged graft to cooperate by plug connector and fastening piece by foam plastic plate and is formed tubular structure; Wherein plug connector is installed in respectively the joint of adjacent foam plastic plate, and by two grooves which is provided with respectively with adjacent foam plastic plate longitudinal tubule (L tubule) to both sides peg graft and cooperate; Fastening piece is positioned at the port of ventilation duct, comprises that being installed on respectively the foam plastic plate transverse tube is criss-cross hoop spare to the sectional area on each limit, and each hoop part reclines with corresponding foam plastic plate by the link that is installed on adjacent foam plastic plate angle respectively; Link comprise with the outside of adjacent hoop spare on one side against fan-shaped junction surface, connect the two ends consistent with adjacent foam plastic plate angle angle on it, every end is respectively equipped with and binds round the upper and lower both sides of part cooperates two the in opposite directions grooves of pegging graft, Yi Bian be provided with and bind round the slit that is slidingly matched outside the part between the groove.
In order to improve the join strength of plug connector and foam plastic plate, prevent that foam plastic plate from skidding off from the plug connector groove, the internal surface of plug connector groove outer end also is provided with pawl, can tighten foam plastic plate when assembly unit.
Foam plastic plate, plug connector, hoop spare and link are four, and two grooves are mutually vertical on the described plug connector, and the both sides of described link are mutually vertical; The cross section that namely becomes by inlaying grafting assembly is the ventilation duct of rectangle.
Than prior art, the utlity model has following advantage:
(1) standard piece can board-like packed and transported, and Assembling, volume are little.
(2) same specification pipeline weight ratio PP material, pvc material are light by 75%, lighter by 90% than glass steel material, easy for installation.
(3) heat insulation: central air-conditioning pipe no longer needs thermal insulation layer.
(4) noise reduction: reduce ventilation noise about 50%.
(5) low cost of manufacture 50%, cost of transportation low 80%.
