Abstract
The utility model discloses a structure for sealing a detachable connection portion of a dust collector. A connection head is provided with a sealing ring in a sleeved mode, and the middle of the sealing ring is an arc-shaped protruding portion. Due to the fact that the section of the sealing ring is arc-shaped, when an external arc is stressed, the sealing ring moves towards the center of a circle in an allowable range, flexible matching is formed instead of rigidity matching, and accordingly, sealing performance is improved, reliable sealing is guaranteed and meanwhile, the service life of the sealing ring is long.
Description
Technical field
the utility model relates to a kind of structure that is applied to realize the sealing of the dust catcher place of removably connecting.
Background technology
well-known dust catcher often adopts hard tube to realize air channel docking, in order to prevent that leaking appears in air-flow in the docking of air channel, need to adopt sealing ring to realize the place's of removably connecting sealing, and existing sealing ring is because be that rigidity coordinates through repeatedly easily losing efficacy after plug, cause flow leakage, impact is used.
Utility model content
the utility model object is: a kind of structure that is applied to realize the sealing of the dust catcher place of removably connecting is provided.
the technical solution of the utility model is: a kind of structure that is applied to realize the sealing of the dust catcher place of removably connecting, connector is arranged with sealing ring, and the centre of sealing ring is an arc protuberance.
on the basis of technique scheme, further comprise following attached technical scheme:
the even thickness of sealing ring.
sealing ring has POM material.
connector is provided with the annular groove of accommodating sealing ring, and has gap between the inner side of arc protuberance and annular groove.
the utility model advantage is:
the utility model is arc by sealing ring cross section, and when externally circular arc is stressed, there is surplus displacement at Xiang Yuan center, and cooperation has just become flexible cooperation like this, rather than rigidity cooperation, improves thus sealing property and guarantees that sealing is reliable, and the life-span is longer simultaneously.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is cutaway view of the present utility model;
fig. 2 is the partial schematic diagram of Fig. 1;
fig. 3 is the stereogram of sealing ring in the utility model;
wherein: 10, connector; 20, sealing ring; 22, arc protuberance; 30, handle; 40, flexible pipe.
The specific embodiment
embodiment: as Figure 1-3, the utility model provides a kind of specific embodiment that is applied to realize the structure of the dust catcher place of removably connecting sealing, and it comprises connector 10, is set in the sealing ring 20 on connector 10, the flexible pipe 40 that is fixed on the handle 30 on connector 10 and is connected with connector 10.The centre of sealing ring 20 is arc protuberances 22.The even thickness of sealing ring 20.Sealing ring 20 has POM material.Connector 10 is provided with the annular groove of accommodating sealing ring 20, and has gap between the inner side of arc protuberance 22 and annular groove.
the utility model is arc by sealing ring cross section, and when externally circular arc is stressed, there is surplus displacement at Xiang Yuan center, and cooperation has just become flexible cooperation like this, rather than rigidity cooperation, improves thus sealing property and guarantees that sealing is reliable, and the life-span is longer simultaneously.
certainly above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, within all should being encompassed in protection domain of the present utility model.
