Problems solved by technology

[0002] The air duct is generally made of phenolic material, and it is mainly used for the return air of the air conditioning system in the clean room of the building or workshop. When the air duct is installed, the air duct is made on site, and then the air duct is hoisted on the top, and the air duct is connected by the air duct joint. Connection. There are many kinds of existing air duct joints. Generally speaking, there are still many defects. The main performance is that because the branch pipes are generally made of phenolic material, the strength is low, and the joints are more likely to break and leak. Now Some air duct joints fail to make up for this defect of the air duct. In addition, the main structural form of the existing air duct joints is a strip-shaped plug-in connection. Although the four sides of the air duct are sealed butt joints, However, the four corners of the branch joint are easily leaked through right-angle buckles.

Embodiment 1

[0031] Such as Figure 1-6 As shown, a plug-in air pipe joint of the present invention includes a strip-shaped female buckle 1 and an L-shaped male buckle 2, such as image 3 As shown, one side of the bar-shaped female buckle 1 is provided with a U-shaped groove 5 stuck on the side plate 4 of the air duct end 3, and the other side of the strip-shaped female buckle 1 is provided with a Figure 4-6 As shown, the L-shaped chuck 6 docked with the L-shaped male buckle 2, the outer layer of the L-shaped male buckle 2 is an L-shaped supporting plate 7, and a sealing block 8 is arranged in the right angle of the L-shaped supporting plate 7, and the L-shaped The inner surface of the strip plate 9 of the supporting plate 7 is provided with a double-hook chuck 10 which cooperates with the L-shaped chuck 6 and engages with each other.

[0032] Such as Figure 4-6 As shown, the width B of the L-shaped pallet 7 is greater than or equal to four times the width A of the double-hook chuck 10...

Embodiment 2

[0040] Such as Figure 1-6 As shown, a plug-in air pipe joint installation method includes steps:

[0041] Step 1) According to the four unilateral lengths (F-2G) of the square air duct end 3, intercept the bar-shaped female buckle 1 of the same length; also intercept the length E of the matching L-shaped male buckle 2;

[0042] Step 2) Put the intercepted strip female buckle 2 through the U-shaped groove 5 and glue it on the side plate 4 of the air duct end 3, and then use rivets for riveting;

[0043] Step 3) Butt the two air duct ends 3 with the strip female buckle 1 installed with each other;

[0044] Step 4) Then insert the double-hook clamp head 10 of the L-shaped male buckle 2 into the L-shaped clamp head 6 of the strip-shaped female buckle 1 on the two air duct ends 3, and apply glue on the sealing block 8, and insert the L-shaped male buckle The buckle 2 is fully inserted, and then the remaining single-sided side panels 4 on the air duct end 3 are connected in turn ...

Abstract

The invention discloses an opposite inserting type air pipe joint and a mounting method thereof. The opposite inserting type air pipe joint comprises strip-shaped female buckles and L-shaped male inserting buckles. A U-shaped groove clamped in a side plate at the corresponding end of an air pipe is formed in one side of each strip-shaped female buckle, and an L-shaped chuck in butt joint with the corresponding L-shaped male inserting buckle is arranged on the other side of each strip-shaped female buckle. An L-shaped supporting plate is arranged on the outer layer of each L-shaped male inserting buckle. A sealing block is arranged in the right angle of each L-shaped supporting plate. A double-hook chuck matched and connected with the corresponding L-shaped chuck in a clamped manner is arranged in a long-strip plate of each L-shaped supporting plate. The L-shaped supporting plates are arranged on the outer layers of the L-shaped male inserting buckles, the width B of each L-shaped supporting plate is larger than or equal to four times of the width A of the corresponding double-hook chuck, the L-shaped supporting plates can achieve a certain supporting function on two air pipe joints, and therefore the problem that the two air pipe joints are broken due to the fact that a connector is mounted can be eliminated.
