Specific embodiment

Description is made to the preferred embodiment of the utility model below with reference to the Figure of description provided.

As shown in Figure 1 and Figure 2, the utility model provides a kind of connection plugging device, is set between equipment 1 and pipeline 2, with Play the role of connection, closure.Have in equipment 1 interface that be inserted into for pipeline 2, pipeline 2 and interface for clearance fit not It is directly fixed with pipeline 2.Connection plugging device includes rotating ring 3 and fixed structure, and fixed structure is fixed on equipment around interface 1, rotating ring 3 is placed on pipeline 2 and can be embedded in fixed structure with radially sliding.

Specifically, fixed structure includes two stationary rings 4, several distance pieces 5, several connectors 6 and washer 7.The pad of annular Circle 7 is simultaneously posted by equipment 1 around interfaces, and the quantity of washer 7 can be one or more, in the present embodiment there are five.Two Stationary ring 4 is placed on pipeline 2, and the internal diameter of stationary ring 4 is significantly greater than the outer diameter of pipeline 2 therefore does not contact with pipeline 2, and distance pieces 5 is located at Between two stationary rings 4 therefore make to be formed between two stationary rings 4 at regular intervals.The thickness of distance pieces 5 is equal or slightly larger than rotating ring 3 Thickness, therefore be embedded into rotating ring 3 can in the spacing between two stationary rings 4.Multiple distance pieces 5 along stationary ring 4 it is circumferential uniformly between Every arrangement, and distance pieces 5 is hollow tubular structure.Connector 6 is bolt, and the quantity of the quantity of connector 6 and distance pieces 5 It is equal, every a connection piece 6 successively pass through after a stationary ring 4, corresponding distance pieces 5, another stationary ring 4 and washer 7 with 1 screw thread of equipment It connects and locks, so that the entirety of fixed structure can be fixed with equipment 1.Certainly, the effect of distance pieces 5 is only for determining that two is quiet The distance between ring 4 is made into non-hollow shape, such as cylindrical body, can also realize this effect.

The two sides of rotating ring 3 and two stationary rings 4 face opposite with rotating ring 3 are polished surface, rotating ring 3 and two stationary rings 4 it Between be equal or slightly greater than for gap 0 clearance fit, it is ensured that rotating ring 3 can be fitted closely with two stationary rings 4, prevent foreign matter logical It crosses, and can make rotating ring 3 that can radially slide with respect to stationary ring 4.When rotating ring 3 be close proximity to one of stationary ring 4 and between another one between When gap is 1.6mm, then the foreign matter greater than 1.6mm can not just pass through this connection plugging device.Rotating ring 3 is also matched with pipeline 2 for gap It closes, i.e., rotating ring 3 can be locked on pipeline 2, can also have certain minim gap between 2 outer peripheral surface of pipeline.

As shown in figure 3, first plugging plate 31 and second plugging plate 32 of the rotating ring 3 including arc, the two of the first plugging plate 31 It is separably docked with the both ends of the second plugging plate 32 respectively at end.Preferably, being respectively equipped with one at the both ends of the first plugging plate 31 Groove 33 and a holding section 34 are also respectively equipped with a groove 33 and a holding section 34 at the both ends of the second plugging plate 32, pass through Holding section 34 is caught in opposite groove 33 can be realized the first plugging plate 31 and fixes with the second docking for plugging plate 32.Equally , holding section 34 can be separated from each other from the first plugging plate 31 after abjection in groove 33 with the second plugging plate 32.By the dynamic of annular Ring 3 is designed as the structure of this two semicircles composition, can have determined in pipeline 2 and the relative position of equipment 1 at the construction field (site) In the case where rotating ring 3 is set on pipeline 2, no longer need to movement pipeline 2 and be inserted in from end, facilitate operation.Likewise, above-mentioned Structure made of this two semicircles dock can also be used with washer 7 in stationary ring 4.

Multiple groovings are equipped on first plugging plate 31 and the second plugging plate 32, these groovings are radially extended along rotating ring 3 And it is divided into the first grooving 35 for extending to inward flange and extends to outer peripheral second grooving 36.The two of every one second grooving 36 Side is respectively equipped with one first grooving 35, therefore three groovings including one second grooving 36 and two first groovings 35 can be considered one Group, multiple groups grooving are circumferentially spaced on rotating ring 3.

By the way that the first grooving 35, the second grooving 36 are arranged on rotating ring 3, so that the structure of rotating ring 3 has certain flexibility, it can Occur a certain range of flexible deformation in radial directions, therefore rotating ring 3 is adapted to the actual size error of pipeline 2, makes this The live adaptability for connecting plugging device is stronger.

One, the rotating ring 3 being placed on pipeline 2 is embedded in the fixed structure for being fixed on interface, makes fixed structure and rotating ring 3 It is formed and is blocked in pipeline 2 and interface connection, can prevent a certain size foreign matter from entering；

Two, pipeline 2 is no longer directly fixed with equipment 1, and the vibration on pipeline 2 can be by the relatively fixed structure of rotating ring 3 It slides and is weakened, play certain vibration isolation effect, be conducive to keep 1 structural intergrity of equipment.

Three, this connection plugging device may be provided at any position on pipeline 2, be not limited to the end of pipeline 2, flexible arrangement Property it is high；

Four, the structure of this connection plugging device is simple, is only bolted, convenient for disassembly and assembly, easy to replace, maintain.

Above disclosed is only the preferred embodiments of the utility model, and effect is to facilitate those skilled in the art Understand and implement accordingly, the interest field of the utility model cannot be limited with this certainly, therefore special according to the present utility model application Equivalent variations made by sharp range still falls within the range that the utility model is covered.
