Description

Air supply assembly Technical Field The utility model relates to the field of air supply equipment, in particular to an air supply assembly. Background The air supply device generally comprises an air supply end and an air source, an air supply pipe is arranged between the two. The air supply device is applied to aspects of production and life, such as rescuing patients in hospitals or supplying oxygen to severe patients, supplying oxygen when mining workers detect that the ore vein enters the ground, and supplying oxygen when divers dive. However, the existing air supply equipment is overlarge in size, inconvenient to store, troublesome to take in an integrated design, and inconvenient to maintain in a later period when the weight is large, so that when the air supply equipment is needed to be used, the air supply equipment is long in time, and the hidden danger of untimely air supply exists. Disclosure of utility model In order to solve the problems that the air supply equipment is inconvenient to be assembled and inconvenient to be maintained in the later period due to the integral design, the air supply assembly is provided with: an air supply assembly adopts the following technical scheme: the air supply assembly comprises an air supply pipe, wherein a first connecting piece and a second connecting piece are respectively arranged at two ends of the air supply pipe, the first connecting piece comprises a first guide pipe and a first insertion pipe which are connected through threaded fit, the first guide pipe is connected with the air supply pipe through a first connecting ring, and at least one protruding block is arranged on the outer surface of the first connecting ring; The second connecting piece comprises a second guide pipe and a second insertion pipe, the second guide pipe is provided with a connecting rod in a penetrating mode, two ends of the connecting rod are arranged outside the second guide pipe, a slideway used for guiding the connecting rod is arranged in the second insertion pipe, and the end point of the slideway is provided with a clamping groove matched with the connecting rod. Through adopting the technical scheme, the air supply pipe is connected with the air supply end through the first connecting piece, because the air supply end is often close to the human body, the first guide pipe is connected with the first insertion pipe through threads, the connection stability is guaranteed, the first connecting ring and the bulge play a role in saving force when the first guide pipe is screwed down, the air supply pipe is connected with the air source through the second connecting piece, and because the air source is often far away from the human body, the air supply pipe is matched with the slideway through the connecting rod, the quick installation is guaranteed to enable the air source to be linked as soon as possible to realize air supply, meanwhile, the problem of difficulty in unlocking after the air supply pipe is knotted is avoided through the split design, and the air supply end, the air duct and the air source are stored respectively and maintained at later stages conveniently. Further, the bump is provided with a protrusion for pointing to the first conduit. The protrusion is adapted to be directed towards the first conduit for ease of installation when under water or under low light conditions. Further, a first baffle is arranged at the bottom of the first cannula, and a filter screen matched with the inner diameter of the first catheter is arranged on the first baffle. The air supply pipe is inevitably mixed with ambient air in the installation process, the filter screen can effectively isolate ambient air from entering the air supply end, and meanwhile, air supply of an air source can be filtered, so that harm to a human body is avoided.
