Description

Technical Field

[0001] The utility model relates to the field of air ducts, and particularly relates to a novel bayonet connection air duct with a gasket. Background Technique

[0002] The air duct is the main material in the process exhaust system. Its main function in the exhaust system is to exhaust, discharging harmful gases in areas such as factory workshops and production sites to the outside, so as to ensure that the internal environment of the above areas meets the production requirements.

[0003] After retrieval, a flexible air duct universal tee with the publication number CN214581728U includes: a first pipe section, both ends of which are provided with connection mechanisms detachably connected to adjacent flexible air duct segments. The two ends of the flexible air duct segment are respectively provided with a male chain of a zipper and a female chain of a zipper; the connection mechanism includes two inner and outer circles of zipper tapes arranged circumferentially along the first pipe section. The two circles of zipper tapes are respectively the male chain and the female chain of the zipper, and the pulling directions of the male chain and the female chain are opposite; a second pipe section, one end of which is connected to a through hole opened in the middle of the first pipe section. For the flexible air duct universal tee of the present application, the first pipe section does not need to distinguish between the male chain end and the female chain end during production and installation, and can be connected to adjacent flexible air duct segments. It can not only solve the connection problem in the production and installation process of flexible air duct system components, but also avoid the situation where docking cannot be achieved due to temporary adjustment of the pipe section.

[0004] For the existing connection air ducts in the above patents, most of them are connected and assembled by the method of flange thread connection. However, the flange connection method requires threaded connection through multiple bolts, and such an assembly method is too cumbersome. For the air ducts in the above comparative cases, a zipper method is used for assembly. However, the zipper method not only lacks tightness, but also has firmness problems during installation.

[0005] Therefore, it is necessary to invent a novel bayonet connection air duct with a gasket to solve the above problems. Content of the Utility Model

The bayonet connection is carried out between the first ferrule and the second ferrule at one end of the air duct main body. Then, press the pressing plate on one side to make the buckling block tilt up. When the tilted buckling block is stuck behind the second ferrule, release the pressing plate. Through the setting of the torsion spring, the pressing plate and the buckling block rebound and are stuck behind the second ferrule, thereby improving the firmness of the connection of the air duct main body, so as to solve the problems put forward in the above background technique.

[0007] In order to achieve the above purpose, the utility model provides the following technical solution: a novel bayonet connection air duct with a gasket, including an air duct main body;

A sealing groove is formed on one side surface of the second ferrule, and a sealing gasket is movably connected inside the sealing groove;

[0009] A buckle assembly is fixed to the upper and lower sides outside the first ferrule and is used for ferrule connection between air duct main bodies. The buckle assembly includes a connection seat, a connecting rod, a torsion spring, a pressing plate, and a buckle. The connection seat is fixed to the upper and lower sides of the first ferrule. A connecting rod is provided on one side of the connection seat. A torsion spring is provided on the outside of the connecting rod. One side of the torsion spring is fixedly connected to a pressing plate, and a buckle is fixedly installed below one side of the pressing plate;

[0010] A telescopic air duct is arranged inside the air duct main body and is used to adjust the length of the air duct.

[0011] Preferably, the pressing plate and the buckle are integrally provided. The pressing plate and the buckle are L-shaped. The second ferrule is movably clamped to the first ferrule through the buckle.

[0012] Preferably, a connection sleeve is fixedly installed at one end of the telescopic air duct. A sealing ring is provided on the outside of the connection sleeve. A limiting groove is formed inside the air duct main body.

The buckle assembly 8 includes a connection seat 801, a connecting rod 802, a torsion spring 803, a pressing plate 804, and a buckle 805. The connection seat 801 is fixed on the upper and lower sides of the first ferrule 2. A connecting rod 802 is provided on one side of the connection seat 801, a torsion spring 803 is provided outside the connecting rod 802, a pressing plate 804 is fixedly connected to one side of the torsion spring 803, and a buckle 805 is fixedly installed below one side of the pressing plate 804;

[0029] The telescopic air duct 9 is arranged inside the air duct main body 1 for adjusting the length of the air duct. The telescopic air duct 9 is connected to the second ferrule 4 at one end of another air duct main body 1 through the first ferrule 2 at one end of the air duct main body 1, and a sealing gasket 7 is provided between the two, providing a sealing effect and also facilitating the connection. After the first ferrule 2 and the second ferrule 4 are threadedly connected and fixed, press the pressing plate 804 on one side to make the buckle 805 tilt up. When the tilted buckle 805 is stuck behind the second ferrule 4, release the pressing plate 804. Through the setting of the torsion spring 803, the pressing plate 804 and the buckle 805 rebound and are stuck behind the second ferrule 4, thereby improving the firmness of the connection of the air duct main body 1.

When the first ferrule 2 rotates, the internal convex block 3 presses against the sealing gasket 7 on one side of the second ferrule 4, thereby enhancing the sealing performance between the two. When the first ferrule 2 and the second ferrule 4 are about to be sleeved together, press the pressing plate 804 on one side of the first ferrule 2 to make the buckle 805 tilt up. When the tilted buckle 805 is stuck behind the second ferrule 4, release the pressing plate 804. Through the torsion effect of the torsion spring 803, the pressing plate 804 and the buckle 805 rebound and are firmly stuck behind the second ferrule 4, thus improving the firmness of the connection of the air duct main body 1. After the air duct main bodies 1 are sleeved and connected, according to the required installation length, pull out the telescopic air duct 9 from the air duct main body 1.
