Embodiment 1

[0029] Example 1. Figure 1-10 As shown, the plug-in square plastic ventilation duct is mainly composed of a plastic plate 1 and a plastic connector. The cylindrical structure is formed by the plastic plate 1 being plugged and fitted with the plastic connector, and the plastic plate 1 and the socket of the plastic connector are bonded together by glue.

[0030] The plastic plug-in connector is fitted with the two sides of the adjacent plastic plate 1 through two grooves provided thereon.

[0031] The plastic connector includes a right-angle profile connector 2 and an I-shaped connector 3 .

[0032] The right-angle profile connector 2 includes two first square grooves 21 perpendicular to each other, and two adjacent plastic plates 1 in the length direction of the ventilation duct are respectively inserted into the same first square groove 21 of the same right-angle profile connector 2 and The two plastic plates 1 and the plastic inserts are staggered in length so that one end...

Abstract

The invention discloses an inserting type square plastic ventilation duct which is characterized in that plastic sheets are inserted and matched through plastic inserting pieces to form a tubular structure, and the inserting parts of the plastic sheets and the plastic inserting pieces are bonded together through glue. The inserting type square plastic ventilation duct disclosed by the invention issimple and compact in overall structure, firm in connection, convenient in production and processing, low in use cost, good in sealing performance of the ventilation duct, high in ventilation efficiency and convenient in disassembly and maintenance.

Description

technical field [0001] The invention relates to a ventilation duct, in particular to a ventilation duct for heating and cooling of an air-conditioning system. Background technique [0002] In the central air-conditioning system, heat-insulating air ducts are mainly used to transport hot and cold air. Traditional combined ventilation ducts generally use iron sheet ducts, glass fiber reinforced plastic ducts and glass magnesium ducts. Iron sheet air ducts require technicians to manually beat and bite the iron sheet, which is costly, complicated construction, long cycle, and low work efficiency; FRP air ducts require mold making, glue coating, and maintenance. The construction process is complicated, the cycle is long, the work efficiency is low, and the quality is not easy to control In addition, the service life of the glass fiber reinforced plastic air duct is only ten years, and it is difficult to maintain; the air duct is composed of A-grade glass magnesium boards, such a...
