Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the perspective view of the utility model embodiment;
Fig. 4 is the symmetrical structural representation of radial hole that sleeve is arranged;
In figure: 1 screw rod; 11 cross recesses; 2 nuts; 3 resilient pads; 4 flat gaskets; 5 sleeves; 51 cross recesses; 52 through holes; 53 elongated slots; 6 nuts.
Embodiment
As shown in Figure 1, 2, 3, this dismountable expansion bolt mainly comprises screw rod 1, nut 6, sleeve 5, also comprises the flat gasket 4 be nested with on screw rod 1, compression spring 3, and with the nut 2 of screw rod 1 screw-thread fit.
This screw rod 1 is the screw rod of Full Thread FT, namely whole screw rod 1 all arranges screw thread.Screw rod 1 right side is provided with cross recess 11, and this cross recess inserts, to use screw-driver rotating screw bolt for the cutter head of cruciate flower screw-driver.As other mode of executions: the cutter groove of screw rod right side also can straight groove, and straight groove can coordinate with the cutter head of flat mouth screw-driver.
The left end of described nut 6 is cecum, and right-hand member is opening end, and cecum diameter is greater than opening end diameter.The screw thread matched with screw rod 1 is provided with in nut 6.
The internal diameter of described sleeve 5 is greater than the external diameter of screw rod 1.The left end of sleeve 5 is provided with elongated slot 53 vertically, elongated slot 53 be provided with many and many elongated slots 53 around the uniform setting of circumference of sleeve 5.The right side of sleeve 5 is provided with the cutter groove inserted for screw-driver head end; In this embodiment, the cutter groove on sleeve 5 right side is cross recess 51.As other mode of executions, the cutter groove on sleeve 5 right side also can be straight groove, and straight groove can coordinate with the cutter head of flat mouth screw-driver.
Sleeve 5 is disposed radially the radial hole 52 for hooking sleeve 5.In this dismountable expansion bolt, described radial hole is through hole.As further mode of execution, described radial hole 52 can arrange multiple, and multiple radial hole is arranged along the axially-aligned of sleeve 5.Like this can according to actual conditions, select suitable radial hole to coordinate with hook, and progressively go forward one by one move the position of hooking, can play laborsaving and protect the effect of EXPANSION ANCHOR BOLTS installation place.
In this embodiment, the external diameter of nut 6 right-hand member is less than the internal diameter of sleeve left end; The left end external diameter of described nut is greater than the internal diameter of sleeve, and the outer peripheral surface of such nut 6 is taper.
During use, first electricity consumption is drilled in the hole that body surface gets out corresponding size, the left end of screw rod 1 and nut 6 is assembled, and related for the left end of screw rod nut 6 is inserted in the hole of having bored together, is nested with by sleeve 5 on screw rod 1, and the right-hand member of nut 6 inserts the left end of sleeve 5.The object borehole jack will fixed again is on screw rod 1, successively flat gasket 4, resilient pad 3 are set on screw rod 1 again, last mounting nuts 2, rotate clockwise nut 2 with spanner, and tightened, moving axially of nut finally can make sleeve 5 move axially, the left end of sleeve 5 is set on the right-hand member of nut 6, outer peripheral surface due to nut 6 is taper, so nut 6 can strut the left end of sleeve 5 gradually, sleeve 5 is expanded locking in hole.
EXPANSION ANCHOR BOLTS is taken off if want, need first to unclamp nut 2, successively nut 2, elastic washer 3, plain washer 4 and institute's mounting article are taken off, the cross recess 11 of screw rod 1 end is rotated counterclockwise with screw-driver, screw rod 1 is taken off, by the cross recess 51 of sleeve 5 end, sleeve is unscrewed again, take off sleeve 5 with the radial hole 52 that the steel wire of one end buckle hooks on sleeve 5.Finally take out nut 6.
In order to ensure that sleeve is when pulling out, pulling force be along quill to power, vertical stress component can not be produced and to cause in sleeve pull-out process stuck, radial hole can be set to arrange in sleeve axis bilateral symmetry, corresponding drag hook is provided with two hooks, hold a radial hole respectively, can ensure that the direction of power can not offset like this.The setting of the radial hole of which as shown in Figure 4.
In the utility model, "left", "right" is the relative position relation adopted in order to aspect description scheme structure, the restriction that can not form the utility model protection domain as absolute position understanding.
Above-described embodiment is only preferred embodiment, and the utility model is not only confined to above-described embodiment.
