Description
Technical field
Present invention relates particularly to one kind to move back pin mechanism.
Background technology
After axle sleeve as shown in Figure 1, coordinated by screw rod with it is embedded in wall, generally by manually or mechanically turning
Dynamic screw rod, pin is moved back in realization, but easily takes axle sleeve out of during screw rod revolution, causes work that can not be normally carried out.
The content of the invention
For above-mentioned technical problem, the present invention provides one kind and moves back pin mechanism.
One kind moves back pin mechanism, including：
The body of rod drives the rotation of its own by artificial or machine；
First end is fixedly connected with the body of rod, first end inner hollow, which is provided with one group it is axially symmetric on the body of rod
Strip hole；
One rotation section, including a threaded portion and a fixed part, the fixed part is placed in inside first end, by one simultaneously
Penetrate through above-mentioned strip hole and the axis pin realization rotation section of the fixed part and the connection of first end；The threaded portion is equipped with outer
Screw thread.
Preferably, first end is integrally formed or welds with the body of rod.
Preferably, the outer end face of the first end extends the second end, is formed between first end and the second end
One ring ladder.
Preferably, the strip hole is ellipticity；The long axis of strip hole and the axis of the body of rod form an acute angle；The length
The tooth in angle and threaded portion external screw thread that the long axis and body of rod axis in hole are formed is consistent with the angle that body of rod axis is formed.
The present invention provides one kind to move back pin mechanism, and rotation section is placed in first end by axis pin, and rotation section rotates,
By axle sleeve precession wall or other for carrying in the object of axle sleeve, when moving back pin, the second end withstands axle sleeve, rotation section convolution,
Pin is moved back in realization, will not take axle sleeve out of, and mechanism can be used for lathe manually, can disposably complete whole flow process, keep away
Exempt to do over again.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
Embodiment：
Shown in Fig. 2 to 4, the present invention includes：The body of rod 1 drives the rotation of its own by artificial or machine；The body of rod 1 is generally fixed
In on lathe or passing through manual rotation.
First end 2 is fixedly connected with the body of rod 1,2 inner hollow of first end, which is provided with one group on 1 axis of the body of rod
To symmetrical strip hole 22；First end 2 and the body of rod 1 can be integrally formed, and can also be welded together, and guarantee is fixedly connected i.e.
It can.
One rotation section 3, including a threaded portion 31 and a fixed part 32, fixed part 32 is equipped with through hole 34, described solid
Determine portion 32 to be placed in inside first end 2, penetrate through the pin of 32 through hole 34 of above-mentioned strip hole 22 and the fixed part simultaneously by one
Axis 33 realizes rotation section 3 and the connection of first end 2；The threaded portion 31 is equipped with external screw thread.
The outer end face of the first end 2 extends the second end 21, and one is formed between first end 2 and the second end 21
Ring ladder.
The strip hole 22 is ellipticity；The long axis of strip hole 22 forms an acute angle with the axis of the body of rod 1；The strip
The angle one that the tooth on 31 external screw thread of angle and threaded portion that the long axis and 1 axis of the body of rod in hole 22 are formed is formed with 1 axis of the body of rod
It causes.
Implementation principle：Axle sleeve is as shown in Figure 1, the threaded portion 31 of itself and rotation section 3 coordinates precession wall, the second end at this time
21 withstand axle sleeve, rotate backward the body of rod 1, and first end 2 is driven to circle round, and in the moment of rotation, the second end 21 withstands axle sleeve, turn
Dynamic portion 3 is moved in convolution, axis pin 33 in the body of rod 1 in strip hole 22, and mobile route is consistent with the route that rotation section 3 is turned round,
Realize that the threaded portion 31 of rotation section 3 and the loosening of axle sleeve, rotation section 3 can easily depart from rotation section 3 and axle sleeve after loosening,
Pin is moved back in realization.
The present invention provides one kind to move back pin mechanism, rotation section 3 is placed in first end 2 by axis pin 33, rotation section 3
Rotate, by axle sleeve precession wall or other for carrying in the object of axle sleeve, when moving back pin, the second end 21 withstands axle sleeve, rotates
Portion 3 circles round, and pin is moved back in realization, will not take axle sleeve out of, and mechanism can be used for lathe manually, can disposably complete entire
Flow avoids doing over again.
A variety of modifications of these embodiments will be apparent for those skilled in the art, herein
Defined General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.
