Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, needs are understood, " big nut ", " primary nut " and " intermediate nut " are for ease of describing the utility model and simplified characterization, and can not be interpreted as instruction or hint relative importance or imply the quantity indicating indicated technical characteristic.
Refer to Fig. 1-3, the connector 100 that the utility model preferred embodiment provides, comprise big nut 10, primary nut 20, and for the intermediate nut 30 that connects big nut 10 and primary nut 20 and inserted link 40.The connector 100 of the present embodiment is for being connected and fixed two pile tubes, particularly, in the process preparing pile tube, first the big nut 10 in this connector 100 and primary nut 20 are set on prestressed steel bar 101, and prepare two pile tubes to be acted on by other preparation technology, then realize being connected and fixed two prestressed steel bars 101 by external intermediate nut 30 and inserted link 40, that is realize being connected and fixed two pile tubes.Bonding strength between being appreciated that in order to be acted on two pile tubes, can between to be acted on two pile tubes the connector 100 of the multiple the present embodiment of annular array.
Wherein, described intermediate nut 30 is applied in this connector 100, is specifically assemblied in the side opening part of big nut 10 towards primary nut 20, and is be connected and fixed threadably between this intermediate nut 30 and big nut 10.For the ease of the assembling of intermediate nut 30, the end of the intermediate nut 30 of the present embodiment side is wherein provided with flange 31, and the external diameter of described flange 31 is greater than the aperture of described big nut 10, like this when intermediate nut 30 is assembled on big nut 10, by this flange 31 by spacing for this intermediate nut 30 openend at big nut 10, and can judge whether be seated between intermediate nut 30 and big nut 10 intuitively.
Described inserted link 40 is applied in this connector 100, is on the one hand fix the intermediate nut 30 being assembled to big nut 10, is fix with primary nut 20 on the other hand, and then realizes being connected and fixed big nut 10 and primary nut 20.Particularly, the outer peripheral face of described inserted link 40 wherein side is offered as flank, to match with the flank on primary nut 20 inside wall, realizes being connected being threadedly fixed between this inserted link 40 with primary nut 20.Further, the external diameter of described inserted link 40 is greater than the aperture of described primary nut 20, can know whether inserted link 40 and primary nut 20 are seated so intuitively.The outer peripheral face of described inserted link 40 opposite side offers annular groove 41, and described annular groove 41 matches with intermediate nut 30, its length is slightly larger than the height of intermediate nut, and offer groove 42 in a side end face of the contiguous annular groove 41 of this inserted link 40, to make inserted link 40 when plugging in fitting has on the big nut 10 of intermediate nut 30, deformation can be there is in the end of this inserted link 40 by the extruding of intermediate nut 30, that is can successfully insert in intermediate nut 30 in order to this inserted link 40, then to be coordinated with abutting between intermediate nut 30 by annular groove 41 that inserted link 40 offers and realize spacing for the opposite side of this inserted link 40 in intermediate nut 30, and intermediate nut 30 is assemblied on big nut 10, so just achieve the effect be fixed on by inserted link 40 on big nut 10.
As from the foregoing, successfully intermediate nut 30 is inserted in order to realize this inserted link 40, the inserted link 40 of the present embodiment is in the process inserting intermediate nut 30, suitable deformation can be there is in its extruding being subject to intermediate nut 30, this connector 100 needs when specifically selecting inserted link 40 to be prepared from elastomeric material like this, and spring steel material specifically can be had to be prepared from.
Wherein, the groove 42 that the end face of described inserted link 40 offers is cross recess, and in described cross recess, its separation of part of contiguous inserted link 40 end face is equal, and the separation of remainder reduces gradually from the end face direction away from inserted link.Further, the center of circle line of described cross recessed center line and described inserted link 40 coincides.
As preferred version of the present utility model, described inserted link 40 is provided with rounding 43 in the end of the side of contiguous annular groove 41, inserts intermediate nut 30 more swimmingly to make inserted link 40.And, the annular groove 41 that described inserted link 40 side outer peripheral face offers its for abutting against with intermediate nut 30 inclined plane that the end face coordinated is set to match with intermediate nut 30.Be appreciated that in inserted link 40 and be set to inclined plane for the contact surface abutted against with intermediate nut 30, bonding strength when inserted link 40 interacts with intermediate nut 30 can be improved like this.
In sum, connector provided by the utility model, by the vibrational power flow of inserted link and intermediate nut, this connector is applied in pile tube use, be connected and fixed threadably by the side of inserted link and primary nut, opposite side abuts against with intermediate nut and coordinates, and intermediate nut is fixed on big nut threadably, achieve by spacing for the opposite side of inserted link on big nut, and then realize being connected and fixed of large and small nut; And inserted link and primary nut and intermediate nut, abut setting mutually between intermediate nut with big nut, this addresses the problem when two pile tubes being connected and fixed with this connector, between two pile tubes, there is the technical problem of rocking; Simultaneously inserted link and primary nut, and being connected and fixed threadably respectively between intermediate nut and big nut, is not only convenient to assembling, and bonding strength is between any two high.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
