A kind of cantilever as shown in Figure 1, Figure 2 and Figure 3 rotates resilient structures after resigning, including is hinged on by rotary shaft 9
Cursor 1 in frame, the outer end of the cursor 1 is connected by rotating drawstring 2 with frame, and described the inner of cursor 1 is provided with
The inner side of rotary shaft 9 is additionally provided with base 10 in push rod 5, the push rod 5 and the elastic connection of cursor 1, the frame, described to rotate
During 1 pull-up of arm, push rod 5 offsets with base 10.
The cursor 1 is provided with blind hole, the push rod 5 insertion blind hole, and be provided between push rod 5 and blind via bottom by
Pressing spring 3.One end that the push rod 5 is in contact with compression spring 3 is provided with limited block, the opening of the blind hole and is additionally provided with push rod
Fixed plate 4, the limited block is engaged push rod 5 is spacing in blind hole with push rod fixed plate 4.The structure is used to cause push rod not
Depart from cursor, push rod is lost during preventing transport or use.
Roller 6 is additionally provided with the base 10, the roller 6 is rotatably arranged on roller mount 8, the top by roller shaft 7
The one end of bar 5 away from compression spring 3 is additionally provided with end plates 51, during 1 pull-up of cursor, and end plates 51 offset with roller 6.
The side of the upper roller 6 of base 10 is additionally provided with bolt 12, and the bolt 12 is horizontally disposed with, and the cursor 1 is drawn
When rising, end plates 51 offset with bolt 12.The roller mount 8 be two, the bolt 12 be arranged on two roller mounts 8 it
Between.Limit switch 11 is additionally provided with the cursor 1, the driving lever of the limit switch 11 is located under the end plates 51 of push rod 5
Side.
The present invention increases spring and flexible push rod structure in cursor, and the end plates of push rod front end are plane steel plate,
Base increases roller and bolt arrangement with cursor spring relevant position, when bending angle increases to certain angle, top
Rod end panel is contacted with roller, and when angle increases again, push rod is retracted, and spring is pressurized, and suitable spring force is obtained from suitable spring,
Workover treatment to terminate back boom smoothly to turn back origin-location.Further, since cursor is tumbler, therefore base is set
Roller, as bending angle increases, push rod front plan steel plate is rolled relative to roller, is unlikely to hard friction.
Meanwhile, if spring force is inadequate, artificial top-hung arm can also be carried out by bolt, its bending is gone back.Separately
Outside, can by set cursor step down during motor current limit value go carry out bending angle control, it is to avoid bending angle
Spend and cause device damage greatly.Or can increase limit switch on cantilever, when push rod retract apart from it is long when touch limit
Bit switch, so that controlled motor is shut down.
The rotation drawstring two ends of the present invention are separately fixed in cursor front end and drive shaft, when being ready for rotary motion
When the rotation of arm is stepped down, now spring is in free state：
After drive shaft turns, rotate drawstring and pull cursor allow bit manipulation around the upward bending of rotary shaft, when resigning angle [alpha] compared with
When big, the end plates of push rod front end face are contacted with roller, and when α continues to increase, spring is pressurized, and push rod is retracted, and angle [alpha] is got over
Greatly, spring force is bigger, and push rod extension elongation is tapered into during angle becomes greatly, so that the elastic force of spring becomes larger, it is real
Border can normal resilience to meet cursor from suitable spring in using.
When bending angle is too big, usual equipment is got rusty or other reasonses due to rotary shaft, cause cantilever not can from
Own bending is gone back, it is necessary to loop wheel machine or other instruments are retracted, and is wasted time and energy, while probably due to misoperation, bending angle
Even more than 90 ° of degree, then cause to damage to equipment.
The advantage of this structure is that spring force is bigger, and the electric current of motor is bigger, can set in a control program when angle [alpha] is bigger
The electric current permissible value of motor when stepping down surely, alarms as more than if, or the placement limit switch at roller, once angle of rotation is spent
Greatly, limit switch works to cut off motor power.Certainly, this patent can also make if recoil of spring power is inadequate
Manually operated with bolt, cantilever top is returned.
It should be pointed out that above example is only the representative example of the present invention.The present invention can also have many deformations.It is every
Any simple modification, equivalent variations and modification that essence according to the present invention is made to above example, are considered as belonging to this
The protection domain of invention.
