Detailed description of the invention
Fig. 1 is the main sectional view of first embodiment；
Fig. 2 is B-B cross-sectional view in Fig. 1；
Fig. 3 is the structure chart of thread bush；
Fig. 4 is the structure chart of tightening sleeve；
Fig. 5 is the main sectional view in second embodiment.
Specific embodiment
The utility model is described further below with reference to Fig. 1 to Fig. 5.
Embodiment one:
A kind of stud installation tool, including screw 10, the thread bush 20 that is disposed with tapped through hole, to be disposed with screw thread logical
The tapped through hole of the tightening sleeve 30 in hole and spanner for turning screw 10, thread bush 20 and tightening sleeve 30 be it is coaxially arranged,
Thread bush 20 is located at the top of tightening sleeve 30, and the bottom end that screw 10 passes through the tapped through hole of thread bush 20 and screw 10, which is located at, tightens
In the tapped through hole of set 30, the tapped through hole bottom end of tightening sleeve 30 is the screw terminal of stud, the bottom of screw 10 and double end
The top of bolt abuts.
In the present embodiment, to realize that stud is screwed in from the tapped through hole bottom end of tightening sleeve 30, the bottom end of screw 10 is answered
Higher than the bottom end of 30 tapped through hole of tightening sleeve.
The nut that the top layout of screw 10 has for spanner clamping, nut may be designed as hexagonal (hexagon)nut, i.e. nut is folder
Hold structure.
The distance between thread bush 20 and tightening sleeve 30 are at least a screw pitch, and herein thread bush 20 and tightening sleeve 30 it
Between distance be the threadingly shortest distance between the bottom end of through-bore axis direction thread bush 20 and the top of tightening sleeve 30.This reality
It applies in example, which is a screw pitch.
One end of thread bush 20 towards tightening sleeve 30 is shaped to inverted L shape structure, and thread bush 20 is towards one end of tightening sleeve 30
Including two first end faces 21, there is difference in height between two first end faces 21, form first between two first end faces 21
Drop face 22.One end of tightening sleeve 30 towards thread bush 20 is shaped to L-type structure, and tightening sleeve 30 is wrapped towards one end of thread bush 20
Two second end faces 31 are included, there is difference in height between two second end faces 31, form second between two second end faces 31 and fall
Poor face 32.First drop face 22 and the second drop face 32 are opposite, and there are gaps between the first drop face 22 and the second drop face 32.
In the present embodiment, the bottom end of thread bush 20 and the top of tightening sleeve 30 are disposed with interlocking structure, the first drop face 22
Interlocking structure is constituted with the second drop face 32.
The position of thread bush 20 and tightening sleeve 30 is well placed, screw 10 is screwed in the tapped through hole of both this, until
The lower end surface of nut is bonded with the top end face of thread bush 20, then stud is revolved from the tapped through hole bottom end of tightening sleeve 30
Enter, and abuts the top of stud and the bottom end of screw 10.In the present embodiment, position at the abutting of stud and screw 10
In the tapped through hole of tightening sleeve 30, i.e., the bottom end of screw 10 passes through thread bush 20 and enters in the tapped through hole of tightening sleeve 30.
When using the tool mounting stud, screw 10 is pulled by spanner, screw 10 can be with screw thread when just starting
Set 20 rotates together, but since there are gap, thread bush 20 and tightening sleeve 30 can be around between thread bush 20 and tightening sleeve 30
Screw 10 relatively rotate so that the first drop face 22 and the second drop face 32 are mutually withstood, and obviously thread bush 20 with
Less than one screw pitch of distance that tightening sleeve 30 relatively rotates, therefore the first drop face 22 and the second drop face by mutually withstanding
Interlocking is realized between 32 thread bush 20 and tightening sleeve 30.Threaded connection, tightening sleeve 30 i.e. between thread bush 20 and screw 10
Threaded connection between screw 10 the two be threadedly coupled between be staggered, i.e., the threaded connection at two cannot link.While because
Both hands bolt is withstood for screw 10, therefore can prevent stud from relatively rotating with tightening sleeve 30 during installation.Pass through
The above structure, the torque on spanner can reach tightening sleeve 30 through thread bush 20 from screw 10 and then stud is tightened on peace
It fills in object structure.
It screws stud to need to remove tool later, screw 10 is reversely pulled by spanner, by the first drop face
22 and second mutually withstand the interlocking structure to be formed between drop face 32, and screw 10 drives thread bush 20 and tightening sleeve 30 to revolve together
Turn, is detached from tightening sleeve 30 and stud, tool can be removed from stud.
In the present embodiment, to reduce the frictional force at the top of stud with 10 bottom of screw, screw 10 is designed as tip
Screw.
Embodiment two:
The difference between this embodiment and the first embodiment lies in: such as Fig. 5, if the diameter of the stud of installation and screw 10 is straight
Diameter is different, and can also design the tapped through hole in tightening sleeve 30 is stepped hole, so then screw 10 should be passed through thread bush 20 and entered
In the tapped through hole of tightening sleeve 30.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to
State embodiment, within the scope of knowledge possessed by those of ordinary skill in the art, can also do not depart from it is practical
Various changes can be made under the premise of novel objective.
