Abstract
The utility model discloses a kind of tracheae swivels, including outer tooth and fuse, flange is set on the fuse, the centre position limiting slot A of flange, the limiting slot A is polygonized structure, and O-ring milling limiting slot is arranged in the junction of the fuse and outer tooth, and O-ring milling limiting slot is arranged in the top of flange, the O-ring milling limiting slot is internally provided with O-ring, and lock pin is arranged in the lower part of the fuse；The utility model is simple in structure, the effectively locked O-ring of effect limited by O-ring, the utility model requirement on machining accuracy is low, be not in the case where O-ring tilts, effectively prevent gas leakage, and the utility model is rotated by the way that limiting slot A is designed to polygonized structure after placing hose buckling, it is easy to use, it is highly practical.
Description
Technical field
The utility model is related to a kind of connector, specifically a kind of tracheae swivel.
Background technology
Tracheae be for air gun, air compressor machine is mating, connection structures for pneumatic tools such as power drill, pneumatic drill, air guns, gas
Pipe fitting have advanced structure, it is functional, easy to use, do not have to welding, need not will piping flaring etc. series of advantages, because
This, ferrule-type compression joint is widely used in the hydraulic pressure of all kinds of machineries, pneumatic system.Gas-tpe fitting has advanced structure, property
Energy is good, easy to use, do not have to welding, need not will be piped the series of advantages such as flaring, and therefore, ferrule-type compression joint is answered extensively
For in the hydraulic pressure of all kinds of machineries, pneumatic system.But the cutting ferrule accuracy of manufacture of ferrule-type compression joint is higher, due to complex process,
It should not manufacture sporadicly or in small batches, need professional production.
But the lock airway dysfunction of existing gas-tpe fitting is not perfect, machining it is not perfect, not precisely, easy to produce gap
Disadvantage, it is therefore desirable to make improvements.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of tracheae swivel
Problem.
To achieve the above object, the utility model provides the following technical solutions：
Flange, the centre position limit of flange are arranged on the fuse for a kind of tracheae swivel, including outer tooth and fuse
Position slot A, the limiting slot A is polygonized structure, and O-ring milling limiting slot, O-ring milling is arranged in the junction of the fuse and outer tooth
Limiting slot is arranged in the top of flange, and the O-ring milling limiting slot is internally provided with O-ring, and the lower part setting of the fuse is inserted
Core.
As further program of the utility model：Outer nut is arranged in the bottom of the outer tooth, leads between outer tooth and fuse
The effect connection for crossing riveting, relatively rotates between outer tooth and fuse.
As further program of the utility model：External screw thread is set on the outer tooth, swivel passes through externally threaded
Effect is connect with pneumatic equipment.
As the utility model further scheme：Limiting slot B is set on the outer wall of the lock pin.
Compared with prior art, the utility model has the beneficial effects that：The utility model is simple in structure, is limited by O-ring
The effectively locked O-ring of the effect of position, the utility model requirement on machining accuracy is low, is not in the case where O-ring tilts, effectively shuts out
Exhausted gas leakage, and the utility model is rotated, user by the way that limiting slot A is designed to polygonized structure after placing hose buckling
Just, highly practical.

Specific implementation mode
The technical solution of this patent is described in more detail With reference to embodiment.
- 5 are please referred to Fig.1, a kind of tracheae swivel, including outer tooth 1 and fuse 2, the bottom setting of the outer tooth 1 are outer
Nut 4 is connected by the effect of riveting between outer tooth 1 and fuse 2, is relatively rotated between outer tooth 1 and fuse 2, on the outer tooth 1
External screw thread 3 is set, and swivel is connect by the effect of external screw thread 3 with pneumatic equipment, and flange 5, flange are arranged on the fuse 2
5 centre position limiting slot A6, the limiting slot A6 is polygonized structure, and O shapes are arranged in the fuse 2 and the junction of outer tooth 1
Milling limiting slot 7 is enclosed, O-ring is washed limiting slot 7 and is arranged in the top of flange 6, and the O-ring milling limiting slot 7 is internally provided with O-ring
8, lock pin 10 is arranged in the lower part of the fuse 2, limiting slot B9 is arranged on the outer wall of the lock pin 10, by limiting slot B9 to tracheae
It is limited.
The operation principle of the utility model：O-ring milling limiting slot is arranged with the junction of outer tooth 1 in the fuse 2 of swivel
7, O-ring 8 is limited by the effect of O-ring milling limiting slot 7, and the junction of the fuse of existing swivel and outer tooth
There is no this structure is arranged, during use, the position of O-ring 8 is easy to tilt, and causes lock airway dysfunction not perfect, this reality
O-ring 8 is limited with the novel effect by O-ring milling limiting slot 7, avoids the appearance of this phenomenon, and in limiting slot
At A6, the utility model is designed to polygonized structure, is the junction of tracheae and swivel at this, and existing limiting slot is round
Shape structure, this structure will appear rotation after tracheae connection is withheld, by the way that limiting slot A to be arranged to the structure of polygon,
Improve this disadvantage, the utility model is simple in structure, passes through the effectively locked O-ring 8 of effect of O-ring milling limiting slot 7, this reality
It is low with novel requirement on machining accuracy, be not in the case where O-ring 8 tilts, effectively prevent gas leakage, and the utility model passes through
Limiting slot A6 is designed to polygonized structure, is rotated after placing hose buckling, it is easy to use, it is highly practical.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, one skilled in the relevant art within the scope of knowledge, can also be under the premise of not departing from this patent objective
It makes a variety of changes.
