Description
Technical field
This utility model belongs to technical field of mechanical, further relates to the fixing device of a kind of plug.
Background technology
Plug blocks up mouth unwanted in pipeline exactly, plays sealing process.In modernization industrial part and plasthetics, pressurizing window place of a lot of pipelines, plug is all adopted to carry out plug stifled, such as, the water tank of solar water heater and the water tank of electric heater in process of production, due to adopt sheet material be welded into cylindrical tube shape, it is necessary to its water sealing property is tested, and be typically all employing plug in testing and the jack being arranged on water tank is blocked, in water tank, then pass into the water setting pressure again.
Existing plug is generally easy rigid plastics plug, under the effect of external force, tightly gets lodged on the jack of water tank.This plug meets instructions for use to a certain extent, but its poor sealing, and plug is outer generally circular in cross section, and when having bigger external force, plug is susceptible to rotate and loosens the effect departing from jack and lose plug.
Summary of the invention
In view of this, this utility model is for overcoming above-mentioned technological deficiency, it is provided that the fixing device of a kind of plug, by being arranged to insert the U-shaped claw of the plate that plug round platform two is symmetrically extended, can effectively be fixed by plug, it is to avoid it departs from jack and lost efficacy；Described plate is provided with projection, and described U-shaped claw side is provided with the U-shaped breach corresponding with described projection, and the projection on described plate snaps in the U-shaped breach of described U-shaped claw side, can effectively prevent plug from rotating, secure plug further.
This utility model solves the problems referred to above by techniques below means:
A kind of fixing device of plug, described fixing device includes the jack inserting described plug, described jack two ends are symmetrically extended and are provided with U-shaped claw, the plate that described plug includes round platform and round platform two is symmetrically extended, described round platform is cylindrical shape, its external diameter and described jack internal diameter match, and the round platform of described plug cylindrical shape inserts described jack, and described plate inserts in described U-shaped claw；
Described plate is provided with projection, and described U-shaped claw side is provided with the U-shaped breach corresponding with described projection, and the projection on described plate snaps in the U-shaped breach of described U-shaped claw side.
Further, the round platform of described plug is provided with sealing ring with the junction of described jack.
Further, described sealing ring is rubber ring.
Further, the bossing on described plate snaps in the U-shaped breach of described U-shaped claw side.
The beneficial effects of the utility model are as follows:
1, this utility model is applicable to plug round platform both end extension and forms the plug of plate, by being arranged to insert the U-shaped claw of the plate that plug round platform two is symmetrically extended, can effectively be fixed by plug, it is to avoid it departs from jack and lost efficacy.
2, described in this utility model, plate is provided with projection, described U-shaped claw side is provided with the U-shaped breach corresponding with described projection, projection on described plate snaps in the U-shaped breach of described U-shaped claw side, can effectively prevent plug from rotating, avoid causing plug to come off jack because plug rotates and causing plug effect to be lost efficacy, secure plug further.

Detailed description of the invention
In description of the present utility model, it will be appreciated that, orientation or the position relationship of the instruction such as term " " center ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", " outward " be based on orientation shown in the drawings or position relationship; be for only for ease of description this utility model and simplifying and describe; rather than instruction or imply indication device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.
Term " first ", " second " only for descriptive purposes, and it is not intended that instruction or hint relative importance or the implicit quantity indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can express or implicitly include one or more these features.In description of the present utility model, except as otherwise noted, " multiple " are meant that two or more.
Below with reference to accompanying drawing, this utility model is described in detail, as shown in Figure 1 to Figure 3: the fixing device of a kind of plug described in the present embodiment, described fixing device includes the jack 2 inserting described plug 1, described jack 2 two ends are symmetrically extended and are provided with U-shaped claw 3, in this utility model, the plate 5 that described plug 1 includes round platform 4 and round platform 4 two is symmetrically extended, described round platform 4 is in cylindrical shape, its external diameter and described jack 2 internal diameter match, the round platform 4 of described plug 1 cylindrical shape inserts described jack 2, and described plate 5 inserts in described U-shaped claw 3；By described plug 1 is inserted described jack 2, it is achieved the sealing process of plug 1.This utility model, by arranging the plate 5 of plug 1 extension and being inserted in the U-shaped claw 3 that described jack 2 extends, fastens the connection of plug 1 and jack 2, effectively prevent plug 1 coming off when stress is bigger.
Described plate 5 is provided with protruding 6, and described U-shaped claw 3 side is provided with and described protruding 6 corresponding U-shaped breach 7, and the projection 6 on described plate 5 snaps in the U-shaped breach 7 of described U-shaped claw 3 side.This utility model by snapping in the U-shaped breach 7 of U-shaped claw 3 side by the projection 6 of plate 5, when plug 1 is subject to bigger external force, plug 1, without rotation, blocks plate 5 in combination with U-shaped claw 3, and plug 1 effect was lost efficacy effectively to prevent plug 1 side-to-side movement from causing.
