In.
As with improvement, connecting and have crank on drive screw, one end of described crank rotates with the top of drive screw
Installing, the other end of described crank is fixed with the end of restrictor bar.
As with improvement, described rotary shaft is arranged in a casing, is provided with the case lid pushing down rotary shaft in the end of casing,
Bearing it is provided with between rotary shaft and casing.
As with improvement, described bearing includes upper bearing (metal) and lower bearing, lays respectively at the top and bottom of rotary shaft.
As with improvement, described casing is arranged in outer case by rotating shaft.
As with improvement, between motor output shaft and driving gear, it is provided with reduction box.
As with improvement, being provided with handle on motor, rotating handle can realize the rotating of motor output shaft.
As with improvement, described restrictor bar is single lever-type structure or is fence type structure.
As with improvement, the length of described restrictor bar can be more than 4 meters.
Compared with prior art, the beneficial effects of the utility model are:
Use the drive screw being connected with rotary shaft female thread as power drive mechanism, during work, pass through drive screw
Rotation realize restrictor bar on turn over or transfer, to reach to be turned on and off the purpose of passage；It is without extension spring structure so that whole
The restrictor bar weight that individual drive mechanism can bear is greatly improved, and rigidity is strong, power is sufficient, solves the outfit needed for big crossing
Security hidden trouble when overlength, overweight restrictor bar or fence type restrictor bar.

Detailed description of the invention
It is more fully understood that essence of the present utility model for convenience of those skilled in the art, new to this practicality below in conjunction with the accompanying drawings
The detailed description of the invention of type is described in detail.
As Figure 1-Figure 4, a kind of banister, it is made up of outer case 1, restrictor bar 2 and drive system, described drive system bag
Including: motor 8, the driving gear 11 being connected with motor 8 output shaft, the driven gear 14 being connected with driving gear 11, with driven tooth
The tapped rotary shaft 3 of wheel 14 connection, and the drive screw 17 being engaged with female thread and can moving up and down；Described restrictor bar
2 are connected with drive screw 17, and turn on carrying out under the drive of drive screw 17, transfer action, with realize passage unlatching or
Close.
Wherein, described restrictor bar 2 is more than the lengthening scale-up version single lever-type structure of 4 meters for length or is fence type structure.Described
Motor 8 is clockwise and anticlockwise motor, and motor 8 drives line shaft 10 rotating by reduction box 9, is fixed on the driving tooth on line shaft 10
