Embodiment
Fig. 1 ~ 6 are most preferred embodiments of the present utility model, and 1 ~ 6 pair of the utility model is done furtherly below in conjunction with the accompanying drawings
It is bright.
As shown in Figure 1 and 2, a kind of setscrew for being easy to remove, including expansion sleeve 4, expansion sleeve 4 are the circle of both ends open
Tubular.One end of the self-expanding of inner conical drogue 5 set 4 is fitted into expansion sleeve 4, and one end that expansion sleeve 4 is loaded to inner conical drogue 5 is defined as this easily
In the lower end of the setscrew of dismounting.Fastening cone 6 is fitted into inner conical drogue 5 from the bottom of inner conical drogue 5.At the top of expansion sleeve 4
Opening wash down successively and on be sequentially placed pad 3 and clamp nut 2, fastening bolt 1 coordinates with clamp nut 2 to be installed, tightly
The inner chamber for entering expansion sleeve 4 after clamp nut 2 and pad 3 is sequentially passed through at the upper port of the Self-fastening nut 2 of fixing bolt 1 downwards,
Then the sequentially enter inner conical drogue 5 after be connected with fastening cone 6.
As shown in figure 3, expansion sleeve 4 includes expansion sleeve body 7, in the bottom border of expansion sleeve body 7 along expansion sleeve body 7
Axial direction uniformly offer a plurality of opening, after opening is opened up finishes, the expansion sleeve that remains between adjacent two openings
Body 7 forms a plurality of expansion sleeve expansion piece.Opened up in the both sides of each expansion sleeve expansion piece with the junction of expansion sleeve body 7 scarce
Mouthful forming expansion sleeve cuts root groove 8, and expansion sleeve is cut after root groove 8 opens up and finish, and is more beneficial for expansion sleeve expansion piece and is squeezed it
After deform.
As shown in figure 4, inner conical drogue 5 includes inner conical drogue body 9, inner conical drogue body 9 is up-thin-low-thick taper tubular, inside
The bottom border of tapered sleeve body 9 uniformly offers a plurality of opening along the axial direction of inner conical drogue body 9, and it is finished opening is opened up
Afterwards, the inner conical drogue body 9 remained between adjacent two openings forms a plurality of inner conical drogue expansion piece.Expanded in each inner conical drogue
The both sides of piece and the junction of inner conical drogue body 9, which open up breach and form inner conical drogue, cuts root groove 10, and inner conical drogue, which is cut root groove 10 and opened up, to be finished
Afterwards, it is more beneficial for deforming after inner conical drogue expansion piece is squeezed.In fastening cone 6 opens up from inner conical drogue body 9
One end that tapered sleeve cuts root groove 10 loads inner conical drogue 5.Thinner one end self-expanding covers 4 bottoms and loaded in it in inner conical drogue 5.Inner conical drogue
5 can also be set with successively as needed it is multiple, to increase tensioner effect.
As shown in Fig. 5 ~ 6, fastening cone 6 is up-thin-low-thick conical section including one, and the outer ring of conical section is clamping cone
Body taper surface 11, fasten one end thinner in cone 6 and load from the bottom of inner conical drogue 5 in it.It is downward on the top of fastening cone 6
Offer and run through its axial through hole, and the internal thread coordinated with fastening bolt 1 is offered on the inwall of the through hole.Clamping cone
The internal thread of internal thread and clamp nut 2 inside body 6 is in opposite direction, i.e., does not open up two in two parts up and down of fastening bolt 1
Section respectively with clamp nut 2 and fastening cone 6 simultaneously cooperation and external screw thread in opposite direction.
It is specific to install and use process as described below：
The bottom that clamp nut 2 is coordinated into the self-tightening fixing bolt 1 after the top of fastening bolt 1 first loads pad 3,
Then the lower end of fastening bolt 1 is fitted into expansion sleeve 4 from top to bottom, then takes the bottom loading of the self-expanding of inner conical drogue 5 set 4 swollen
Expansion set 4 is interior and is sleeved on the outer ring of fastening bolt 1.Cone 6 will finally be fastened from the loading of the bottom of inner conical drogue 5 and and fastening bolt
The external screw thread of 1 bottom coordinates installation, completes originally to be easy to the assembling of the setscrew of dismounting.
When in use, the drilling coordinated with the setscrew for being originally easy to remove is formed using rig first on working face,
Then the setscrew for being originally easy to remove is loaded in drilling, and clamp nut 2 is screwed outside working face, in the process screwed
The fastening cone taper surface 11 of middle fastening cone 6 constantly extrudes inner conical drogue 5, while 5 continuous extrusion expansion of inner conical drogue set 4.Inner cone
Set 5 and after expansion sleeve 4 is squeezed, the inner conical drogue expansion piece of its inner conical drogue 5 and the expansion sleeve expansion piece of expansion sleeve 4 are to extending out
, the external diameter of the bottom of expansion sleeve 4 is become big, setscrew and the drilling for being most originally easy to dismounting at last are reliable fixed.
When the setscrew for being originally easy to remove does not use, the reverse rotational fastener nut 2 first outside working face,
Fastening bolt 1 is rotated using instrument after clamp nut 2 is released, now in bore inner due to fastening cone 6 and inner cone
Set 5 is located in expansion sleeve 4 in whole or in part, that is, the border of the inwall to drill by expansion sleeve 4, inner conical drogue 5 and fastens cone 6
Extrude simultaneously and larger frictional force be present, therefore in external rotating fastening bolt 1, fastening cone 6 is due to the extruding of outside
Power rotates without the rotation with fastening bolt 1, and most fastening bolt 1 is taken out from drilling at last, expansion sleeve 4, the and of inner conical drogue 5
Cone 6 is fastened due to not protruding from working face, therefore can be remained in inside working face, so as to ensure that the smooth of working face.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model
Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
Protect scope.
