Technical field
This utility model relates to a kind of armarium, the respirator joint that especially links to each other with respirator.
Background technology
Respirator is respiratory tract critical patient and the visual plant of operation back monitor patients in order to support to breathe; link to each other with patient's mouth and nose from pipeline of end connection of respirator; but patient through regular meeting's rotation head, stand up or other actions; need certain closure with patient's connecting portion; bring inconvenience with a pipeline to patient; limited patient's activity greatly; a little a bit action just need be taken off respirator or from new adjustment lower angle; operate cumbersome; also dangerous, reveal in the middle of taking place easily.
The CN2280527Y patent documentation that Patent Office of the People's Republic of China and on May 6th, 1998 are announced, name is called universal joint of trachea cannula, and this universal joint is formed with a flexible pipe, straight tube and tee T can the free activity of three bit spaces.Adopt corrugated tube as flexible pipe, corrugated tube is a flexible pipe, reverts back to original-packly when adjusting angle easily, and the restoring force of generation affacts on the parts with contact patients, easily patient is produced certain compressing, causes patient's discomfort.
Summary of the invention
This utility model has solved flexible pipe in the prior art and has been easy to generate restoring force patient is caused the shortcoming of certain compressing, provides a kind of and can directly locate the respirator joint that can not cause patient's discomfort after adjusting angle.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of respirator joint, comprise body and the guide way of being located on the body, be provided with crooked passage in the body, guide way is inserted into an end of passage, wherein, guide way and body are matched in clearance, guide way has the first straight portion that inserts passage and is the second straight portion that an angular bend is connected with the first straight portion, the outer circumference surface of the first straight portion is provided with two seals groove at least, be covered with sealing ring in the seal groove, the external diameter of sealing ring is greater than the diameter of the channel end that cooperates with the first straight portion on the body, the upper end of the first straight portion is provided with the angle stopper slot one, has a spacing hole with the corresponding position of angle stopper slot on the body.Guide way and body are matched in clearance, therefore can produce relative rotation between guide way and the body, and guide way itself has certain angle of bend, the needs that can adapt to different angles in conjunction with guide way around the anglec of rotation of body, in the first straight portion of guide way, be provided with seal groove and sealing ring, form by the passage on sealing ring and the body and to closely cooperate, both played the effect of sealing, simultaneously again certain positioning action can be arranged, after rotating to certain angle, elastic force and the pressure between the vias inner walls by sealing ring make guide way be fixed on the body, unrestrictedly rotate in order to prevent simultaneously, also in order to prevent that guide way from deviating from, guide way is provided with the angle stopper slot, and still be spacing hole on the body sidewall, insert spacer pin in the spacing hole, the end of spacer pin snaps onto in the angle stopper slot.
As preferably, passage is at right angles crooked, and first of passage brings out mouthful and the first straight portion matched in clearance, and second to bring out mouthful be the step connector, and the passage in the first end exit is straight wall.The first end exit inner surface make straight wall make sealing ring with can play the better seal effect after straight wall contact, when guide way rotates simultaneously, also can not produce damage to sealing ring.
As preferably, first brings out a mouthful bottom has the step that diameter diminishes, the intermediary aperture of step is less than the external diameter of the first straight portion, first outer wall that brings out mouth is a cambered surface, spacing hole is opened in first and brings out on the sidewall of mouth, the axis of spacing hole and first brings out a mouthful axis normal, also with second to bring out mouthful axis perpendicular.First brings out mouthful the bottom is step, cooperates the degree of depth too big in the time of can placing guide way and cooperates with body, influences use, and first to bring out mouthful outer wall be that cambered surface makes the appearance of body and the appearance transitions smooth of guide way.
As preferably, the outside of spacing hole is a taper hole.Spacing hole is a screwed hole, and its outer end is a taper hole, makes the tail end of spacer pin can sink in the taper hole, can not reach first outer wall that brings out mouthful, prevents scraping.
As preferably, the both sides of body have the installation portion of outstanding body, and the outer surface of installation portion is semicircle, and the centre of installation portion has counterbore, is provided with the handle that an end is a frustum with the equidirectional passage extended spot of installing hole axis on the body.Body is fixed on the installation portion when being connected with respirator.
As preferably, the external diameter of the first straight portion is less than the external diameter of the second straight portion, the shared central angle of angle stopper slot is 178 ° 182 °, the both ends of the surface of angle stopper slot tilt, the inclination angle of end face is 5 °, and the angle stopper slot is arranged on the bearing of trend of the second straight portion centrage and the centrage symmetry of the relative second straight portion.The shared angle of angle stopper slot is 178-182 °, is commonly used with 180 °, makes guide way adjust in an angular range, without the multi-angle rotation, thereby has simplified operation.
As preferably, the bent angle between the first straight portion and the second straight portion is 32 °-38 °, and the second straight portion and the first straight portion external diameter difference are 2-4mm, and first external diameter that brings out mouthful matches on the external diameter of the second straight portion and the body.External diameter difference between the first straight portion and the second straight portion forms a ladder, and this ladder contacts with first end face that brings out mouth on the body, and the external diameter that the external diameter of the second straight portion and first brings out mouth matches, and guarantees that guide way cooperates the back appearance to seamlessly transit with body.
The beneficial effects of the utility model are: guide way and body matched in clearance, rotation is convenient, sealing ring is set on the guide way, carry out the connecting portion sealing by sealing ring, the external diameter of sealing ring is greater than the internal diameter of body channel link, makes can play positioning action after the guide way rotation, and spacing hole on the body and the angle stopper slot on the guide way match, can limit the angle of guide way rotation, thereby simplify adjustment work.
