Abstract

The utility model provides a nylon straight-through. The nylon straight-through is composed of a nylon straight-through body and a round silica gel strip. The whole nylon straight-through body is T-shaped and is formed by integral injection molding through a mold, a semicircular groove is formed in the end face, and a round silica gel strip is pressed into the semicircular groove. Four hollow cavities are formed in the opposite sides of the semicircular groove, and a plurality of barbs are additionally arranged outside cavity bodies of the hollow cavities; only one bolt hole is reserved in the top of the nylon straight-through body; and a plurality of through grooves are formed in the bottom of the frame and are matched with the cold-bridge-preventing double-cavity frame aluminum upper cutter grooves. Four-cavity plug-in connection and anti-cold-bridge middle aluminum stable and reliable connection are adopted, and the overall strength of the unit frame is improved; through the through groove and the round silica gel strip, the installation and positioning of the aluminum frame and the anti-cold-bridge double-cavity frame are more accurate, the sealing is tighter, and the air leakage phenomenon is completely eradicated.

Description

TECHNICAL FIELD

[0001] The utility model relates to combined air conditioning unit in the field of air conditioning equipment, in particular to a kind of nylon straight-through for the frame of combined air conditioning unit with cold bridge prevention middle aluminium and cold bridge prevention double-cavity frame aluminium connection. BACKGROUND

[0002] Combined air conditioning unit frame structure with cold bridge prevention middle aluminium profile is mostly full aluminium material, and cold bridge prevention middle aluminium is connected with cold bridge prevention double-cavity frame aluminium of unit frame, and simple straight-through is generally used, which is inserted into single cavity or directly overlapped and connected by screw fastening.Combined air conditioning unit frame has poor overall strength, is prone to deformation, and has large fitting gap, so air leakage phenomenon is prone to occur, and on-site replacement is also cumbersome. SUMMARY

[0003] In order to solve the drawbacks of the existing combined air conditioning unit frame connection simple tee, the utility model provides a nylon straight-through, which is stably and reliably connected with the cold bridge prevention middle aluminium by four-cavity insertion type connection, and increases the overall strength of the unit frame.The through grooves and round silicone strips make the installation and positioning of the nylon straight-through and the cold bridge prevention double-cavity frame aluminium more accurate and sealed, and prevent air leakage.

[0004] The utility model discloses the technical scheme adopted to solve the technical problems is: provide a kind of nylon straight-through, by nylon straight-through body and round silicone strip composition.Nylon straight-through body is overall T-shaped, by mould integral injection moulding, end face is equipped with semicircular groove, and round silicone strip is pressed into semicircular groove inside, and extrusion seal between the cold bridge prevention double-cavity frame aluminium, prevent air leakage phenomenon;Semicircular groove opposite side has four hollow cavities, and hollow cavity cavity is additionally provided with multiple barbs outside, is tightly combined with the cold bridge prevention middle aluminium, and increases overall strength;Only one bolt hole is reserved at the top of nylon straight-through body, and installation is more convenient;Multiple through grooves are provided at the bottom, and cooperate with the knife groove on the cold bridge prevention double-cavity frame aluminium, so that positioning is more accurate and sealed.

[0005] In practical application, the nylon straight-through is first connected with the cold bridge prevention middle aluminium firmly, and then installed and fixed on the cold bridge prevention double-cavity frame aluminium by bolt.

[0006] The utility model has the advantages that a nylon straight-through is provided, which is stably and reliably connected with the cold bridge prevention middle aluminium by four-cavity insertion type connection, and increases the overall strength of the unit frame.The through grooves and round silicone strips make the installation and positioning of the nylon straight-through and the cold bridge prevention double-cavity frame aluminium more accurate and sealed, and prevent air leakage phenomenon.
