Description
Technical field
The utility model relates to pipe fitting technical field, is specially a kind of Ventilated cap.
Background technique
The Main Function of Ventilated cap is communicated with air, large-sized solid is stoped to enter the effect of pipeline, facilitate pipeline internal drainage, traditional Ventilated cap complex structure, and Ventilated cap is with the process of adaptive Tube formation, support in Ventilated cap is easily disconnected by top, causes this Ventilated cap to lose the effect stoping large-sized solid thing to enter pipeline.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide the Ventilated cap that a kind of structure is simple, intensity is large.
For achieving the above object, the utility model provides following technological scheme: a kind of Ventilated cap, the ventilation part comprising grafting cylinder and be connected with grafting cylinder, the exterior contour of described ventilation part is round table-like, ventilation part comprise top cover and the first back-up ring, described top cover is connected by some supports with the first back-up ring, the joint of described ventilation part and grafting cylinder is provided with annular retaining ring, the internal diameter 0.2cm-0.4cm larger than the internal diameter of annular retaining ring of grafting cylinder, described support comprises the first cambered surface and the second cambered surface, second cambered surface comprises the first camber line and the second camber line, several first camber lines at same circle circumferentially, several second camber lines at same circle circumferentially.
Further, the maximum outside diameter of described first back-up ring is identical with the external diameter of grafting cylinder.
Further, the radical of described support is 16, and forms the air hole of isosceles trapezoid shape between two of arbitrary neighborhood supports.
Further, described grafting cylinder, ventilation part and annular retaining ring pass through injection moulding integrated molding.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: the 1. joint of ventilation part of the present utility model and grafting cylinder is provided with annular retaining ring, the internal diameter 0.2cm-0.4cm less of the internal diameter of grafting cylinder of annular retaining ring, make Ventilated cap in the process of assembling with adaptive pipe fitting, pipe fitting can not immediate roof to support, and then effectively prevent support from being pushed up disconnected or pushing up the phenomenon split and occur.2. support of the present utility model is tile, comprise the first cambered surface and the second cambered surface cambered surface, exterior contour because of ventilation part is round table-like, the design of the first cambered surface, the outer surface of ventilation part is made to reach seamless link, effectively add the surface stress of ventilation part, the intensity of ventilation part is increased, and the second cambered surface is as the internal surface of support, second cambered surface comprises the first camber line and the second camber line, and several first camber lines at same circle circumferentially, several second camber lines at same circle circumferentially, make support uniform force when support.

Embodiment
With reference to Fig. 1-Fig. 5, the utility model is described further.
A kind of Ventilated cap, the ventilation part 2 comprising grafting cylinder 1 and be connected with grafting cylinder 1, the exterior contour of described ventilation part 2 is round table-like, ventilation part 2 comprise top cover 21 and the first back-up ring 22, described top cover 21 is connected by some supports 23 with the first back-up ring 22, described ventilation part 2 is provided with annular retaining ring 3 with the joint of grafting cylinder 1, the internal diameter 0.2cm-0.4cm larger than the internal diameter of annular retaining ring 3 of grafting cylinder 1, described support 23 comprises the first cambered surface 231 and the second cambered surface 232, second cambered surface 232 comprises the first camber line 2321 and the second camber line 2322, several first camber lines 2321 at same circle circumferentially, several second camber lines 2322 at same circle circumferentially.
Ventilation part 2 is provided with annular retaining ring 3 with the joint of grafting cylinder 1, the internal diameter 0.2cm-0.4cm less of the internal diameter of grafting cylinder 1 of annular retaining ring 3, make Ventilated cap in the process of assembling with adaptive pipe fitting, pipe fitting can not immediate roof to support 23, and then effectively prevent support 23 disconnected or push up the phenomenon split and occur by top.
Support 23 is in tile, comprise the first cambered surface 231 and the second cambered surface 232 cambered surface, exterior contour because of ventilation part 2 is round table-like, the design of the first cambered surface 231, the outer surface of ventilation part 2 is made to reach seamless link, effectively add the surface stress of ventilation part 2, the intensity of ventilation part 2 is increased, and the second cambered surface 232 is as the internal surface of support 23, second cambered surface 232 comprises the first camber line 2321 and the second camber line 2322, and several first camber lines 2321 at same circle circumferentially, several second camber lines 2322 at same circle circumferentially, make support 23 uniform force when support.
Further, the maximum outside diameter of described first back-up ring 22 is identical with the external diameter of grafting cylinder 1.
Add the surface stress between the first back-up ring 22 and grafting cylinder 1 joint, make the structural strength of Ventilated cap large, durable in use.
Further, the radical of described support 23 is 16, and forms the air hole of isosceles trapezoid shape between two of arbitrary neighborhood supports 23.
The effect that air hole is mainly communicated with air, is set to 16 by the radical of support 23, and forms the air hole of isosceles trapezoid shape between two of arbitrary neighborhood supports 23, is to prevent large-sized solid material from entering in pipeline.
Further, described grafting cylinder 1, ventilation part 2 and annular retaining ring 3 pass through injection moulding integrated molding.
Employing Shooting Technique manufactures, and Ventilated cap is processed simple, and structure is simple.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
