Be that the utility model advanced optimizes above scheme below: the screw connection structure includes being sleeved on tracheae
The tracheae nut of elbow one end, tracheae nut are T-type structure.
It advanced optimizes: being provided with first annular slot on the tracheae nut.
It advanced optimizes: being equipped with washer in the first annular slot, washer is pressed in the internal screw thread of tracheae nut and shank body
Between hole.
Advanced optimize: the position in the tracheae nut close to one end offers the second annular groove, in the second annular groove
It is equipped with O-ring seal.
Advanced optimize: one end of the gas-pipe bend offers snap ring annular groove, offers deep hole in snap ring annular groove.
Advanced optimize: the limiting device includes the snap ring that one end is equipped with opening, and one end of snap ring is in bending.
Advanced optimize: the internal thread hole of the shank body is cylindrical structure.
In use, by O-ring seal in the second annular groove, tracheae nut installs curved mounted in tracheae after O-ring seal
On head, then by the snap ring annular groove of snap ring threading gas-pipe bend, the gas-tpe fitting component after installing puts into the interior spiral shell of shank body
In pit, by being threadedly engaged connection；
When rock drill works normally, air-flow is entered in shank body by gas-pipe bend.
The utility model realizes shank body and the reliable of gas-pipe bend connects by setting screw connection structure and limiting device
It connects, does not need operator and often replace and repair, improve safety coefficient, reduce operator's gas-pipe bend in use
The security risk that shank body out is hurted sb.'s feelings is collapsed, the labor intensity of worker is reduced, reduces the failure rate of rock drill, the tracheae of the present apparatus
Using being threadedly coupled between elbow and shank body, belong to stationary fit, connection is more firm more reliable, and original gas-pipe bend is in shank body
Belong to dynamic cooperation, moves, steel wire clamping ring is be easy to cause to wear.
The utility model is described in further detail with reference to the accompanying drawings and examples.
