The specific embodiment
Fig. 1 is the structural representation of the scaffold fastening devices that provides of a pair of the utility model.In use, can connect by bolt between the fastening devices.As shown in the figure, semicircle connecting ring 1 one ends are provided with the ear 2 of a semicircle, and this ear 2 is provided with a hole 11, this hole 11 is circular ports, be made up of different hole, two apertures, the radius both sides of the diameter line in less hole add two grooves 18 in the aperture, and the periphery through bigger hole aligns.End at connecting ring 4 also is provided with an ear 3, and this ear 3 also is provided with a hole 12, and this hole 12 also is a circular port.Also have a screw 7 on connecting ring 4, it is used to lay bolt, so that be fixedly connected with other scaffold fastening devices.End at the close ear 2 of connecting ring 1 is provided with two sun pins 8, and is provided with the cloudy groove 9 of two correspondences at an end of the close ear 3 of connecting ring 4.Two connecting rings are made by metal material or harder nonmetals, and they flexibly connect by a latch 6, and can rotate mutually.
Referring to Fig. 2, can further understand the detailed structure in hole 11 and hole 12.The hole 11 of connecting rod 1 is a trapezoidal hole, is made up of the hole 8,11 of two different-diameters.End near sun pin 8 is relatively little hole, an aperture, and this aperture is a bit larger tham the diameter of the screw portion of hold-down screw 5.The other end in hole is relatively large hole, an aperture, and the diameter in this hole is a bit larger tham the length dimension of the arresting lever 10 of hold-down screw 5.In addition, the hole 12 of connecting rod 4 is the maximum size that a diameter is a bit larger tham the hex nut of hold-down screw 5.Like this, the nut of hold-down screw 5 all can be placed in this hole 12.When laying hold-down screw 5, in hole 12, can add proper lubrication oil, get rusty to prevent nut.The middle part in hole radially be provided with two apertures 13 and 19, in the time of in hold-down screw 5 sinks to hole 12, flexible material is poured in the gap in the nut portion of hold-down screw 5 and hole 12 as plumbous 15, under external force, this lead 15 can be squeezed in above-mentioned aperture 13 and 19.Like this, hold-down screw 5 just can be fixed in the hole 12.In the hole 11 of connecting ring 1, because its inner trapezium structure, the joint face in the hole of two different diameters forms a step surface like this, is provided with several for example 2 wedges 14 on step surface, it is used for stoping the past back rotation of arresting lever of hold-down screw 5, thereby prevents that hold-down screw 5 is toward back rotation.
See figures.1.and.2, when connecting ring 1 and 4 rotated mutually, hold-down screw 5 was near hole 11, and arresting lever 10 passes two grooves 18 on the both sides of hole 11 and little bore portion thereof, and enters the macropore part.At this moment, rotational fixation screw 5, arresting lever 10 also rotates and slips over the step of wedge 14.At this moment, because the width of arresting lever 10 is greater than the diameter of the little bore portion in hole 11, like this, hold-down screw 5 just can not come out from hole 11, thereby two connecting rings are interfixed; Simultaneously, because wedge 14 also can suitably prevent the arresting lever 10 of hold-down screw 5 toward back rotation, like this, two connecting rings just can firmly fix together mutually.
In addition, when two connecting rings rotate near the time, the sun pin 8 of connecting ring 1 enters in the cloudy groove 9 of connecting ring 4.Sun pin 8 has the head of a hook-type, and cloudy groove 9 also has a corresponding hook-shaped groove.When the head of hook-type enters hook-shaped groove, can prevent further that two connecting rings from unclamping.
When the size design of two connecting rings, two connecting rings can be designed near semicircle.Like this, when two connecting rings 1 with 4 during mutually near (contact), when hold-down screw 5 enters in the hole 11, can produce pretightning force (tension force), when the arresting lever 10 of trip bolt 5 rotates and after entering wedge, this pretightning force can prevent that arresting lever 10 is free to slide and toward revolution, thereby has further guaranteed the safety of fastener of the present utility model.
Fig. 3, Fig. 4 and Fig. 5 are the schematic diagrames of another embodiment of the present utility model.As shown in the figure, in use, can connect by bolt between two fastening devicess.One end 28 of semicircle connecting ring 1 is provided with the opening 33 of a semicircle.One end 22 of semicircle connecting ring 2 also is provided with an opening.The hold-down screw device comprise an inner nut 21 with one with its screw rod 26 that links to each other by screw thread, one coupled rotating jacket 39 links to each other with described inner nut 21, the afterbody of screw rod 26 is provided with an arresting lever 29, described rotating jacket 39 is positioned at a wherein connecting ring, be rotationally connected mutually by the end 22 of pin 37 with this connecting ring 2, like this, whole hold-down screw device can be around pin 37 about rotations.One end of inner nut 21 links to each other by screw thread, and this part is arranged in rotating jacket 39, and the other end is a hex nut head, and it is positioned at outside the opening of an end 22 of semicircle connecting ring 2.The other end of screw rod 26 is provided with the axial vertical arresting lever 27 with screw rod.28 the both sides with arresting lever 27 corresponding openings respectively are provided with a locking groove 32 in the end, and described arresting lever 27 can be arranged in this groove 32.
Referring to Fig. 4 and Fig. 5, whole hold-down screw device can rotate around pin 37 again.When fixing scaffold, at first rotate the hex nut head of inner nut 21, screw rod 26 is moved upward, like this, when connecting ring 1 near connecting ring 2, screw rod 26 will embed in the opening 33 of connecting ring, at this moment, the hex nut head of reverse rotation inner nut 21 moves downward screw rod 26 again, thereby the part of arresting lever 27 can be embedded in this groove 32.Like this, arresting lever 27 just can not unclamp, thereby makes connecting ring 1 and connecting ring 2 keep interfixing.If loosening two connecting rings, the hex nut head of then rotating inner nut 21 moves upward screw rod 26, makes the part of arresting lever 27 leave groove 32.Inner nut 21 is positioned at rotating jacket 39, and the position that combines with screw rod 26 also is positioned at rotating jacket 39.
It is to be noted, embodiment of the present utility model can make multiple variation, but its essence is owing to adopt described trip bolt device to make two connecting rings fastening, and the fixing trip bolt device of control connection ring is positioned at the hole or the groove of connecting ring, thereby realizes the purpose of this utility model.
