Change the accurate telescoping mechanism of efficiency high, movement locus.
Utility model content
The purpose of this utility model is to overcome technical problem present in above-mentioned motion telescoping mechanism, there is provided one kind is flexible
Stroke reaches the controllable adjustment telescoping mechanism of priming stroke several times.
To achieve these goals, the utility model provides following technical scheme：
A kind of controllable adjustment telescoping mechanism, including underframe and the drive device for being fixed on underframe one end, the underframe are another
End is connected with chute framework, and the chute framework both sides offer symmetrical chute, guiding movable pulley is provided between the chute,
Multistage retractable rod is connected with the chute framework, the drive device is built up on underframe by rear fixed seat, the driving
Device includes cover of driver and the driving rolls being built up in cover of driver, and the driving rolls surface wrap is flexible flexible
Piece, is not exclusively surrounded with multiple return idlers around the driving rolls, the return idler center is provided with return idler axle.
Preferably, being additionally provided with driving piece stopping means in the drive device, the driving piece stopping means is by limiting
Position lower module and the spacing upper module cooperated with it are constituted.
Preferably, the flexible concertina piece stretches out from driving piece stopping means being docked with chute framework, the flexibility
Stretchable sheet section is arc-shaped.
Preferably, gap between the driving rolls outside and return idler more than flexible concertina piece it is vertical away from
From.
Preferably, the expansion link is connected by fixture with the port of chute framework.
The beneficial effects of the utility model are：This controllable adjustment telescoping mechanism is controlled by the type of drive of rotation forces
Stretch out and the indentation of expansion link processed, can reach under small priming stroke space limitation, and flexible stroke reaches priming stroke
Several times, and hydraulic pressure is not needed, the mode such as air pressure, it is only necessary to which machine driving can just provide power, and flexible concertina piece has
There is the cross sectional shape of arc-shaped, ensure that stretchable sheet keeps certain rigidity after extending apparatus mechanism, and then can push away
Dynamic end load.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only used to explain this
Utility model, is not used to limit the utility model.
With reference to Fig. 1 and Fig. 2, a kind of controllable adjustment telescoping mechanism, including underframe 4 are filled with the driving for being fixed on the one end of underframe 4
Put, the other end of the underframe 4 is connected with chute framework 3, the both sides of chute framework 3 offer symmetrical chute, the chute
Between be provided with guiding movable pulley 9, multistage retractable rod 1 is connected with the chute framework 3, the drive device is by rear fixed seat
7 are built up on underframe 4, and the drive device includes cover of driver 6 and the driving rolls 13 being built up in cover of driver 6, described
The flexible stretchable sheet 12 of the surface wrap of driving rolls 13, is not exclusively surrounded with multiple return idlers around the driving rolls 13
10, the center of the return idler 10 is provided with return idler axle 11.
Driving piece stopping means is additionally provided with the drive device, the driving piece stopping means is by spacing lower module 8
And the spacing upper module 5 cooperated with it is constituted, the flexible concertina piece 12 stretches out and chute from driving piece stopping means
Framework 3 is docked, and the section of flexible concertina piece 12 is arc-shaped, between the outside of the driving rolls 13 and return idler 10
Gap is more than the vertical range of flexible concertina piece 12, and the expansion link 1 is connected by fixture 2 with the port of chute framework 3.
