Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
As depicted in figs. 1 and 2, the friction self-locking connector between a kind of steel member, it includes inserted link 12, taper tenon
10th, sleeve 9, back-moving spring 8, safety spring 2, limited block 5, interior positioning tube 1, outer positioning tube 3, location-plate 7 and positioning screw 4.
For the self-locking connection between top steel member 11 and bottom steel member 6, inserted link 12 is fixed on down by screw thread or other modes
On portion's steel member 6, the side of inserted link 12 is provided with first annular tooth.The taper type for being shaped as split-type of taper tenon 10, cone
The second annular tooth is provided with the inner hole wall of shape tenon 10, the shape of the second annular tooth can be with the first ring on the side of inserted link 12
Shape tooth cooperates, and outer wall is circular conical surface.Sleeve 9 is overall annular, and its inner hole wall is circular conical surface, its angle and conic clamp
The outer wall of bamboo shoot 10 is identical, therefore can work in coordination.The contact surface of sleeve 9 and taper tenon 10 is circular conical surface, circular conical surface and circle
The angle of friction that the angle between axis direction is less than taper tenon and sleeve is bored, the principle for applying friction self-locking realizes connection.
Back-moving spring 8 is in compressive state, and certain extruding force is applied with to sleeve 9 makes the inwall of sleeve 9 and the outer wall of taper tenon 10 mutual
Mutually it is adjacent to.Before connection procedure, safety spring 2 is in compression or extended state, and applying certain power to limited block 5 protects limited block
Hold in opening position set in advance, avoid limited block 5 be given a shock or other factors influence and leave opening position set in advance,
So as to avoid taper tenon 9 receive influence and mistake is closed up.Location-plate 7 is fixed on apart from top steel member by positioning screw 4
Can be that back-moving spring 8 and safety spring 2 provide supporting surface at 11 certain position.Interior positioning tube 1 passes through welding or its other party
Formula is connected on location-plate 7, and outer positioning tube 3 is enclosed on the interior outside of positioning tube 1, and safety spring 2 is arranged on interior positioning tube 1 and outer positioning
Between cylinder 3.
Process when the utility model connector uses is as follows：
Before connection procedure, Fig. 3 is seen, the back-moving spring 8 in compressive state applies pressure to sleeve 9, and sleeve 9 passes through it
The circular conical surface extruding taper tenon 10 of inwall, makes taper tenon 10 have the trend closed up；Limit of the taper tenon 10 by limited block 5
System can not close up；Now taper tenon 10 is in open configuration, and the space of endoporus can allow for inserted link 12 to insert；
In connection procedure, Fig. 4 is seen, inserted link 12 is inserted in the endoporus of taper tenon 10, when close to precalculated position, inserted link 12
It is in contact with limited block 5 and promotes limited block 5；After limited block 5 releases the endoporus scope of taper tenon 10 by inserted link 12, place
Sleeve 9 is promoted to be moved along taper surface in the back-moving spring 8 of compressive state, sleeve 9 extrudes taper tenon 10 and closed up；In conic clamp
After bamboo shoot 10 are closed up, the second annular tooth of the inner hole wall of taper tenon 10 and the first annular tooth of the side of inserted link 12 are in contact and stung
Close, realize connection procedure；Connector disclosed in the utility model only needs inserted link 12 inserting taper tenon in connection procedure
In 10 endoporus, it is not necessary to extra operating process.
After the completion of connection procedure, Fig. 5 is seen, when two connected steel members produce the trend of separation, on inserted link 12
It is that pulling force passes to taper tenon 10 by first annular tooth and the second annular tooth, taper tenon 10 is produced the trend of separation,
But because the contact surface between taper tenon 10 and sleeve 9 is circular conical surface, the angle between this circular conical surface and circular cone axis direction
Less than the angle of friction between taper tenon 10 and sleeve 9, friction self-locking state, therefore sleeve 9 and cone are under centrifugation
Relative motion will not occur between shape tenon 10, sleeve 9 hinders the separation trend of taper tenon 10, it is therefore prevented that steel member it
Between separation.
The utility model is not limited to embodiments described above.The description to embodiment is intended to describe above
With explanation the technical solution of the utility model, above-mentioned embodiment is only schematical, is not restricted.
In the case of not departing from the utility model aims and scope of the claimed protection, one of ordinary skill in the art is in this practicality
The specific conversion of many forms can be also made under new enlightenment, these are belonged within the scope of protection of the utility model.
