The Chinese utility model patent of CN201320453126.5 discloses a kind of adjustable anti-skidding positioning mechanism of reinforcing bar bender, fixed
The contact surface of plane plate and positioning seat is provided with mutually matched screw thread anti-skid structure or dentation anti-skid structure, prevents positioning panel
Sliding position is lost by thrust in bending reinforcing steel bar, can be used for fixing the reinforcing bar of different size, while backing pin is rotatably arranged, subtract
Few frictional resistance between reinforcing bar, protects rebar surface not easily damaged.But the structure of above-mentioned adjustable anti-skidding positioning mechanism still may be used
It is further improved, to reduce the cost of manufacture processing.
Utility model content
The purpose of this utility model is to provide one kind to have new structural stepless displacement backing pin plate, is used for moment reinforcement
When fixed steel bars.
Optimal technical scheme used by the utility model is mainly:
Stepless displacement backing pin plate, including

Line,
Backing pin, the backing pin are rotatably provided in backing pin front edge of board；
Adjusting nut, the adjusting nut are installed in cooperation positioning support fix stopper plate in flange shaft.
Further, arc groove is provided on the backing pin plate, the backing pin is cylindrical body, and backing pin is installed in arc groove
In.
Further, the side of the positioning support towards backing pin plate is provided with for the flange shaft to flange shaft positioning and guiding
Set, the flange shaft are connected on the axis hole of positioning support after passing through flange shaft sleeve.
Further, the side of the positioning support towards backing pin plate is provided with limit sliding rail, and the backing pin plate is removable to be set
It sets on limit sliding rail.
Further, the flange shaft sleeve and positioning support are wholely set or are weldingly fixed on positioning support.The limit
Sliding rail and positioning support are wholely set or are weldingly fixed on positioning support.The flange shaft is wholely set or passes through with backing pin plate
Bolt is fixed on backing pin plate.
The beneficial effects of the utility model are:
Stepless displacement backing pin plate in above scheme passes through the axis hole of positioning support by flange shaft, and uses adjusting nut
Fixed, rotating adjusting nut can easily adjust the front-rear position of backing pin plate, realize that stepless displacement is adjusted, be suitable for different size
The bending of reinforcing bar；Mistake sliding position will not be generated using fixation is threadedly coupled；Backing pin on backing pin plate is rotatably arranged, and works as bending
When reinforcing bar, backing pin can protect rebar surface not easily damaged by rotating the frictional resistance greatly reduced between reinforcing bar.With it is existing
Technology is compared, and the structure using flange shaft and shaft hole matching is easy to process, and cost is lower, and is easy to adjust, with bigger excellent
Gesture.
