Abstract
The utility model provides a vent connector, which has convenient installation, simple structure and saved space, and comprises an outer end air vent and an inner end air vent which are mutually communicated. The vent connector is characterized in that retaining clips are arranged around the inner end air vent.
Description
Technical field
This utility model relates to the ventilating joint that is used for instrument, and particularly a kind of convenient installation is simple in structure, saves spatial ventilating joint.
Background technology
The overall structure of existing sphygomanometer mainly is divided into two parts: sphygomanometer and the inflatable part (inflatable oversleeve) that is communicated with sphygomanometer.Be communicated with by steam hose and ventilating joint between sphygomanometer and the inflatable part.Ventilating joint is installed on the sphygomanometer shell by an installing hole on the sphygomanometer shell.The ventilating joint outer end is connected with inflatable part, and the inner is connected with sphygomanometer pressure inside measurement component.Existing ventilating joint great majority are to be fixed on the sphygomanometer shell by screw thread and nut, between the inwall of ventilating joint the inner and sphygomanometer shell, one section passage that engraves screw thread is arranged, nut, is fixed on ventilating joint on the sphygomanometer shell in the threaded passage of this section outside with regard to last.The threaded passage of this section has increased the length of ventilating joint the inner.Because ventilating joint need be fixed by nut in sphygomanometer inside, just need certain nut installing space and nut is installed in the inside of sphygomanometer.This volume control to small-sized sphygomanometer causes certain influence.And nut is installed also will be spent certain set-up time.
The utility model content
At defective that exists in the prior art or deficiency, the inventor studies ventilating joint, has invented a kind of convenient installation, and is simple in structure, saves spatial ventilating joint.
The inventor does not find the ventilating joint that this utility model provides as yet through retrieval.
Technical conceive of the present utility model: a kind of ventilating joint is provided, described ventilating joint has outer end blow vent and inner blow vent, described ventilating joint has clip, and described ventilating joint is fixed on the tool housing by described clip, thereby can avoid using screw thread to be connected with nut.
The technical solution of the utility model is as follows:
A kind of ventilating joint comprises: outer end blow vent that is interconnected and inner blow vent is characterized in that: described inner blow vent periphery is provided with clip.
The clip of described inner blow vent periphery is the four paws structure that comprises four claws.
Described claw has inclined-plane, top and lower bevel, and the bayonet socket between claw root and lower bevel.
Described clip is an elastic component.
Technique effect of the present utility model
Described ventilating joint is fixed on instrument by described clip and comprises on the sphygomanometer shell, need not to engrave screw thread on ventilating joint, has shortened the length of ventilating joint.So and owing to need not to fix by nut and saved certain nut installing space in instrument internal.While directly inserts the tool housing installing hole and gets final product because described ventilating joint is easy for installation, thereby has saved the set-up time of ventilating joint.

Fig. 2 is the structural representation of ventilating joint.
Reference numeral lists as follows:
The 1-ventilating joint, 2-tool housing, 3-clip, the inner blow vent of 4-, 5-outer end blow vent
Specific embodiments:
As shown in Figure 1, ventilating joint 1 of the present utility model comprises clip 3, and clip 3 has four claws, i.e. four paws structure, inner blow vent 4 and outer end blow vent 5.Claw has inclined-plane, top and lower bevel, and the bayonet socket between claw root and lower bevel.Described ventilating joint is used to connect the inside and outside fluidic component of tool housing, comprising: outer end blow vent and inner blow vent are arranged, and the outer end blow vent is connected with the external fluid parts of instrument; Inner blow vent is connected with the fluidic component of instrument internal; Described inner blow vent periphery has two clips at least.Described inner blow vent periphery has four claws.The top of described clip has the inclined-plane, and the root on described clip inclined-plane becomes the bayonet socket of tooth type structures.Described clip has elasticity, when the installing hole on the described ventilating joint insertion tool housing, is subjected to the described clip of extruding of the installing hole on the shell that strain can take place, and shrinks to central authorities.After described clip entered enclosure, described clip can reply original-shape, thereby the bayonet socket of described clip fastened the wall of tool housing owing to lose the extruding of the installing hole on the shell, and described ventilating joint is fixed on the tool housing.
As shown in Figure 2, ventilating joint 1 must will be subjected to the effect of external force from right to left as being installed on the tool housing 2, inserts the installing hole on the tool housing 2.After ventilating joint 1 inserted tool housing 2, outer end blow vent 5 was connected with the fluidic component of instrument outside; Inner blow vent 4 is connected with the fluidic component of instrument internal.Because the external diameter of the clip 3 on the ventilating joint 1 is greater than the internal diameter of installing hole on the tool housing 2.Therefore ventilating joint 1 can not be installed on the tool housing 2 separately under external force.But because the hardness of tool housing 2 is greater than the hardness of joint 1, and the top of the clip 3 of inner blow vent 4 peripheries has the inclined-plane, and ventilating joint 1 material has certain elasticity, therefore enter under external force in the process of tool housing 2 at ventilating joint 1, the clip 3 of inner blow vent 4 peripheries is subjected to the extruding of the installing hole on the tool housing 2 can produce the elastic deformation of shrinking to central authorities by all around.Thereby the reduced diameter of clip 3.The root of clip 3 also will touch the porch of tool housing 2 installing holes when installing hole by tool housing 2 of the chamfered portion of clip 3, stop ventilating joint 1 to continue to move forward.Because the internal diameter of the installing hole on the external diameter of the part that the chamfered portion of clip 3 is following and the tool housing 2 is identical, therefore after the chamfered portion of clip 3 passes through tool housing 2 fully, clip 3 is owing to lose the extruding of the installing hole on the tool housing 2, disappeared by the elastic deformation of shrinking to central authorities all around on the clip 3, ventilating joint 1 returns to original-shape.At this moment, because the chamfered portion external diameter of clip 3 is greater than the internal diameter of the installing hole on the tool housing 2, therefore, clip 3 can't be return backward.Simultaneously because clip 3 ramps are identical with the internal diameter of installing hole on the external diameter of lower part and the tool housing 2, thus ventilating joint 1 and up and down left and right sides four direction move.Thereby the bayonet socket of clip 3 fastens the wall of tool housing 2, and ventilating joint 1 is fixed on the tool housing 2.
When describing this utility model with illustrative scheme, this description is not limited on the limited meaning of being explained.To the difference transformation of illustrative approach, and other creationary scheme, be obvious for the people who grasps above-mentioned technology.Therefore, can expect that any transformation or specific scheme all will drop in the true scope of the present utility model.
