Abstract
The utility model discloses a kind of simple and easy expansion joint, its innovative point is: two adpting flanges comprising symmetrical distribution, be positioned at urceolus and the inner core of order arrangement in left and right between described adpting flange, to be positioned at immediately below described adpting flange, urceolus, inner core and to be all connected with three and substrate in tabular, described inner core welding is arranged on described urceolus, described adpting flange all have for be connected the hole passed, the diameter in the hole of described hole and urceolus and inner core core is consistent, and the diameter in described hole equals the diameter of link end to be worn.By the two ends of band link are each passed through in urceolus in the utility model expansion joint and inner core, diameter due to the hole supplying link to pass of opening in urceolus and inner core equals the diameter of link, thus two link joints add that expansion joint itself can be good at bearing certain axial tension and certain radial force, thus share the stressed of bolt on flange plate, ensure the connection reliability of two links.
Description
Technical field
The utility model relates to a kind of expansion joint, particularly relates to the reliable simple and easy expansion joint of a kind of connection.
Background technique
In the power transmission of link, be connected etc. often through by two link welding, bolt, flange plate, 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 link bulk strength; Flange plate be connected exist by two to be connected respectively with the anchoring of flange plate bolt, the stressed join strength relying on bolted-on completely of such link, when during flange plate connects, two links are stressed, bolt on flange plate needs to bear the power be parallel on link axial direction, will be there is the problem loosened with thread profile 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 join strength large and dismountable link is extremely urgent.
Model utility content
The purpose of this utility model is just to provide a kind of simple and easy expansion joint to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of simple and easy expansion joint, its innovative point is: two adpting flanges comprising symmetrical distribution, be positioned at urceolus and the inner core of order arrangement in left and right between described adpting flange, to be positioned at immediately below described adpting flange, urceolus, inner core and to be all connected with three and substrate in tabular, described inner core welding is arranged on described urceolus, described adpting flange all have for be connected the hole passed, the diameter in the hole of described hole and urceolus and inner core core is consistent, and the diameter in described hole equals the diameter of link end to be worn.
Further, away from the bottom surface of adpting flange side being provided with two for the external support board supported on described substrate, described two dunnages lay respectively at immediately below corresponding adpting flange.
Further, described external support board is hollow structure, and described hollow structure is communicated with the bottom surface of this external support board.
Further, the bottom surface of described external support board is provided with the insulating bush on the bottom surface being bonded in described dunnage.
The beneficial effects of the utility model are:
The utility model is by being each passed through in urceolus in the utility model expansion joint and inner core by the two ends of band link, diameter due to the hole supplying link to pass of opening in urceolus and inner core equals the diameter of link, thus two link joints add that expansion joint itself can be good at bearing certain axial tension and certain radial force, thus share the stressed of bolt on flange plate, ensure the connection reliability of two links.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of simple and easy expansion joint described in the utility model.
In figure: 1-adpting flange, 2-insulating bush, 3-urceolus, 4-inner core, 5-substrate, 6-overcoat.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of simple and easy expansion joint of the present utility model comprises two adpting flanges 1 of symmetrical distribution, be positioned at urceolus 3 and the inner core 4 of order arrangement in left and right between adpting flange 1, to be positioned at immediately below adpting flange 1, urceolus 3, inner core 4 and to be all connected with three and substrate 5 in tabular, inner core 4 welding is arranged on urceolus 3, adpting flange 1 all have for be connected the hole passed, the diameter in the hole of hole and urceolus 3 and inner core 4 core is consistent, and the diameter in hole equals the diameter of link end to be worn.
For the ease of expansion joint, the gravity of self is shared on miscellaneous part, to alleviate the downward shearing force of link joint, away from the bottom surface of adpting flange 1 side being provided with two for the external support board supported on substrate 5, two dunnages lay respectively at immediately below corresponding adpting flange 1.
In the stressed reliable situation of guarantee external support board, for reducing materials, external support board is hollow structure, and hollow structure is communicated with the bottom surface of this external support board.
For reducing scratch miscellaneous part when external support board is shelved on miscellaneous part, the bottom surface of external support board is provided with the insulating bush 2 be bonded on the bottom surface of dunnage.
The utility model is by being each passed through in urceolus 3 in the utility model expansion joint and inner core 4 by the two ends of band link, diameter due to the hole supplying link to pass of opening in urceolus 3 and inner core 4 equals the diameter of link, thus two link joints add that expansion joint itself can be good at bearing certain axial tension and certain radial force, thus share the stressed of bolt on flange plate, ensure the connection reliability of two links.
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 specifications and accompanying drawing content are done, is all contained within interest field of the present utility model.
