Fixed pin be mounted on shell inside round platform on, two nuts further through moving pin be set to outer casing end turntable connect,
End cap is mounted on turntable top；Handle is set to the outside of shell.
Turntable is an annular slab, and annular slab both ends, which are arranged with, stirs bar, using the center of circle as symmetrical centre on turntable, is equipped with two
A arc groove is arranged with straight-line groove in each arc groove clockwise；Arc groove and fixed pin top groove coordinate, straight-line groove with
Moving pin coordinates.
Screw thread in each nut cuts away half in clockwise, and rest part forms two sections together after two nuts fasten
Heart circular arc.
Back-moving spring is equipped between end cap and turntable.
End cap top is equipped with the counter sink for placing spring catch；Turntable is equipped with spring pin hole.
Handle is three, is distributed on the same circumference of shell exterior.
Shell is cylindrical shape, and inside has round platform.
Screw thread longitudinal cross-section is trapezoidal in nut.
The invention has the advantages that and advantage：
1. a kind of fast lifting nut of the present invention, when nut rotate to it is concentric with outer casing bottom hole when, nut is matched with screw rod
It closes, can be lifted in leading screw upper edge threaded line, when being rotated outwardly to tangent with shell, nut is detached from screw rod to be coordinated, at this time
Nut can on screw rod fast lifting, achieve the purpose that save operating personnel's time.
Description of the drawings

Fig. 2 is nut structure diagram in the present invention；
Fig. 3 is turntable structural schematic diagram of the present invention；
Fig. 4 is structure of the invention perspective view；
Fig. 5 is use state diagram of the present invention.
Wherein, 1 is end cap, and 2 be shell, and 3 be handle, and 4 be turntable, and 5 be moving pin, and 6 be nut, and 7 be fixed pin, and 8 are
Arc groove, 9 be U-type groove, and 10 be spring jack, and 11 be spring pin hole, and 12 be fixed pin holes, and 13 be outer casing bottom hole, and 14 be silk

Specific implementation mode
The present invention is further elaborated with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of fast lifting nut of the present invention, including shell 2, handle 3, moving pin 5, nut 6 and solid
Rationed marketing 7, wherein nut 6 is the separate structure of two two halves cylinder halfnuts, and nut 6 is equipped with fixed pin 7 and moving pin 5,
Two nuts 6 respectively by respective fixed pin 7 be mounted on shell 2 inside round platform on, two nuts 6 further through moving pin 5 with
Turntable 4 set on 2 end of shell connects, and end cap 1 is mounted on 4 top of turntable；Handle 3 is set to the outside of shell 2.
Screw thread in each nut 6 cuts away half in clockwise, and rest part forms two sections after two nuts 6 fasten
Isocentric circular arc.Screw thread longitudinal cross-section is trapezoidal in nut 6.As shown in Fig. 2, in the present embodiment, in order to avoid two nuts 6 are being beaten
It opens (non-obvolvent) state with screw rod to interfere, the tooth of nut is cut away into a part, and the tooth of rest part is to be maintained at same
Non-conterminous two sections of stepped tooths on circle.
As shown in figure 3, turntable 4 be an annular slab, annular slab both ends, which are arranged with, stirs bar, on turntable 4 with the center of circle be pair
Title center is arranged with straight-line groove if there are two arc grooves in each arc groove clockwise；Arc groove and 7 top of fixed pin
Slot coordinates, and straight-line groove coordinates with moving pin 5.
In the present embodiment, in order to make fast lifting nut be in normally off, i.e., in normal state nut always with silk
Thick stick coordinates, and back-moving spring is equipped between end cap 1 and turntable 4, while 1 top of end cap is equipped with the countersunk head for placing spring catch
Hole, turntable 4 are equipped with spring pin hole 11.When two 6 obvolvents of nut, spring catch is inserted into counter sink and spring pin hole 11 simultaneously
In, it is ensured that turntable 4 is axial not to be rotated.
As shown in figure 4, handle 3 is three, it is distributed on the same circumference outside shell 2.Shell 2 is cylindrical shape, internal
With round platform, round platform is equipped with fixed pin holes 12.
Fixed pin 7 is located on nut 6, and passes through nut 6, and both ends are lifted one's head, one end and the fixed pin on 2 inside round platform of shell
Hole coordinates, and the other end coordinates with the arc groove on turntable 4.Moving pin is fixed on nut 6, can be transported in straight-line groove with nut 6
Row.
As shown in figure 5, in the use of the present invention, two trapezoidal nuts 6 being connected in shell 2 on round platform are matched with screw rod
It closes, firmly rotary motion turntable 4 stirs bar, and two nuts 6 are dynamic for shaft rotation with respective fixed pin 7 respectively, work as nut outer wall
When being rotated outwardly to tangent with outer casing inner wall, nut is detached from screw rod to be coordinated, and two nuts is made to be transformed into opening by obvolvent state
State is detached from leading screw, and fast lifting nut can axially be fast moved along leading screw at this time, to achieve the purpose that fast lifting；It arrives
Up to after assigned work position, unclamp turntable 4 stir bar, spring-return power (tightening force) effect under, two moving pins 5 respectively with
The fixed pin 7 of respective nut is that axis rotates in straight-line groove, when the rotation of nut 6 is extremely concentric with outer casing bottom hole 13, two ladders
Shape nut 6 coordinates with leading screw (screw rod) again to be held tightly, can continue to rotate along what threads of lead screw one was detained again at this time.
The present invention have it is safe and reliable, be convenient for carrying, be easy to operate, it can be achieved that fast lifting of the nut on screw rod, reaches
To the purpose for saving operating personnel's time.
