Abstract
The utility model discloses a kind of hinge type expansion joint, comprise two connectors be symmetrical set, the face that two connectors face is respectively arranged with the brace be fixedly installed on corresponding connector, also comprise: be positioned at the middleware in the middle of two connectors, the core of this middleware be provided with central axis and this middleware axis being parallel and with the expansion tube of middleware interference fit, the two ends of this expansion tube respectively screw connect on the brace of corresponding side; Brace is the projection be welded as a whole with connector, and bump diameter is much smaller than the diameter of connector; Screwed pipe is respectively arranged with between middleware and two connectors.By being provided with the middleware of expansion tube between two connectors, middleware is utilized to be connected with two connectors, because middleware and expansion tube are interference fit, thus ensure expansion tube and middleware together stressed, another because brace diameter is much smaller than the diameter of connector, thus reduce the impact on the intensity of connector own as far as possible.
Description
Technical field
The utility model relates to a kind of expansion joint, particularly relates to a kind of hinge type expansion joint.
Background technology
In the power transmission of connector, be connected etc. often through by two connector welding, bolt, ring flange, damage as welding also exists certain a connection piece the problem that must overall scrap; Bolt also exists high strength occasion and works long hours and need regularly fastening problem and reduce the problem of connector bulk strength; Ring flange is connected to also exist to be needed on connector, to open one perpendicular to the hole on connector length direction, and adopt bolt or screw to connect, thus weaken the bonding strength of connector itself, another ring flange connects the machining accuracy also needing to ensure ring flange, and when in ring flange connection, two connectors are stressed, bolt on ring flange needs to bear the power be parallel on connector axis direction, will be there is the problem loosened with form of thread wearing and tearing in the bolt that therefore works for a long time, the screw just needing periodic maintenance for this reason or more renew; In view of the above circumstances, provide a bonding strength large and dismountable connector is extremely urgent.
Utility model content
The purpose of this utility model is just to provide a kind of hinge type expansion joint to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of hinge type expansion joint of the present utility model, comprise two connectors be symmetrical set, the face that two connectors face is respectively arranged with the brace be fixedly installed on corresponding connector, its innovative point is also to comprise: be positioned at the middleware in the middle of described two connectors, the core of this middleware be provided with central axis and this middleware axis being parallel and with the expansion tube of described middleware interference fit, the two ends of this expansion tube respectively screw connect on the brace of corresponding side; Described brace is the projection be welded as a whole with described connector, and described bump diameter is much smaller than the diameter of described connector; Screwed pipe is respectively arranged with between described middleware and two connectors.
Further, the two ends of described expansion tube and the link position of described brace are all positioned at described screwed pipe, and the diameter in the hole supplying described expansion tube and described brace to pass in screwed pipe equals the diameter of described expansion tube.
Further, the expansion tube outer wall between described expansion tube and described middleware is provided with insulating barrier.
Further, the length of described insulating barrier equals the length of described expansion tube.
Further, centered by described projection, axis being parallel is in the cylindrical structure of described expansion tube axis, and described bump diameter equals expansion tube diameter.
The beneficial effects of the utility model are:
The utility model by being provided with the middleware of expansion tube between two connectors, middleware is utilized to be connected with two connectors, because middleware and expansion tube are interference fit, thus ensure expansion tube and middleware together stressed, another because brace diameter is much smaller than the diameter of connector, thus reduce the impact on the intensity of connector own as far as possible.
In addition, for ensureing the bonding strength between brace and expansion tube further, by setting up screwed pipe between connector and middleware, thus ensure the connection reliability at link position place.
One layer insulating is set between expansion tube and middleware, prevents both phase mutual friction and damage expansion tube.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of hinge type expansion joint described in the utility model.
In figure: 1-connector, 2-screwed pipe, 3-middleware, 4-expansion tube, 5-screw, 6-brace, 7-insulating barrier.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of hinge type expansion joint of the utility model comprises two connectors 1 be symmetrical set, the face that two connectors 1 face is respectively arranged with the brace 6 be fixedly installed on corresponding connector 1, its innovative point is also to comprise: be positioned at the middleware 3 in the middle of two connectors 1, the core of this middleware 3 be provided with central axis and this middleware 3 axis being parallel and with the expansion tube 4 of middleware 3 interference fit, the two ends of this expansion tube 4 respectively screw 5 connect on the brace 6 of corresponding side; Brace 6 is the projection be welded as a whole with connector 1, and bump diameter is much smaller than the diameter of connector 1; Screwed pipe 2 is respectively arranged with between middleware 3 and two connectors 1.
In order to can the power that brace 1 and expansion tube 4 junction are subject to be transmitted on screwed pipe 2, the two ends of expansion tube 4 and the link position of brace 6 are all positioned at screwed pipe 2, and the diameter in the hole supplying expansion tube 4 and brace 6 to pass in screwed pipe 2 equals the diameter of expansion tube 4.
In order to prevent phase mutual friction between expansion tube 4 with middleware 3 from damaging expansion tube 4, expansion tube 4 outer wall between expansion tube 4 and middleware 3 is provided with insulating barrier 7, and the length of insulating barrier 7 equals the length of expansion tube 4.
In order to be transmitted on screwed pipe 2 by the power that brace 1 and expansion tube 4 junction are subject to greatest extent, centered by projection, axis being parallel is in the cylindrical structure of expansion tube 4 axis, and bump diameter equals expansion tube 4 diameter.
By being provided with the middleware 3 of expansion tube 4 between two connectors 1, middleware 3 is utilized to be connected with two connectors 1, because middleware 3 and expansion tube 4 are interference fit, thus ensure that expansion tube 4 and middleware 3 are together stressed, another because brace 6 diameter is much smaller than the diameter of connector 1, thus reduce the impact on the intensity of connector 1 own as far as possible.
Those skilled in the art do not depart from essence of the present utility model and spirit, various deformation scheme can be had to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby interest field of the present utility model is limited to, the equivalent structure change that all utilization the utility model descriptions and accompanying drawing content are done, is all contained within interest field of the present utility model.
