Abstract
The utility model relates to door lifter field, especially a kind of position-limit mechanism of banister, it comprises baffle plate, limiting plate and limit switch, the outer casing inner wall that described baffle plate is arranged on banister is positioned at the top of the output shaft of banister, described limiting plate is set on the output shaft of banister, two side angulations that described limiting plate contacts with output shaft are 90 degree, and the quantity of described limit switch is two, and are separately positioned on two sides that limiting plate contacts with output shaft; The baffle plate of output shaft both sides is provided with gag lever post straight down, and the limit switch when position of gag lever post and the side of the limiting plate of this side are positioned at horizontal level is corresponding.The position-limit mechanism of this banister, structure is simple, is driven the rotation of limit switch by the rotation of gear output shaft, positioning bolt nut is utilized to locate, achieve to limit switch rotate spacing, ensure that the adjustable angle of restrictor bar, the limitation that its product is used is less.
Description
Technical field
The utility model relates to door lifter field, especially a kind of position-limit mechanism of banister.
Background technology
The spacing of position-limit mechanism on existing banister is all fixing, and banking stop can regulate, so the adjustment of switch angle need realize by regulating banking stop, this just causes the limitation of open angle, and regulates trouble relatively; In addition movement also has a protective device, but banking stop and protective device separate, and which increases cost of production.
Utility model content
The purpose of this utility model is deficiency in order to solve above-mentioned technology and provides a kind of structure simple, easy for installation, the position-limit mechanism of the banister that stability in use is good.
In order to achieve the above object, the position-limit mechanism of the banister designed by the utility model, it comprises baffle plate, limiting plate and limit switch, the outer casing inner wall that described baffle plate is arranged on banister is positioned at the top of the output shaft of banister, described limiting plate is set on the output shaft of banister, two side angulations that described limiting plate contacts with output shaft are 90 degree, and the quantity of described limit switch is two, and are separately positioned on two sides that limiting plate contacts with output shaft; The baffle plate of output shaft both sides is provided with gag lever post straight down, and the limit switch when position of gag lever post and the side of the limiting plate of this side are positioned at horizontal level is corresponding.
Technique scheme, in use, when restrictor bar is positioned at level, on limiting plate, wherein the limit switch of side contacts with gag lever post; And when restrictor bar in output shaft rotation process rotates equally, limiting plate rotates simultaneously, when limiting plate rotate cause that on limiting plate, the limit switch of opposite side contacts with gag lever post time, then output shaft stops operating, this structure can be carried out spacing to restrictor bar during restrictor bar rotation, and the power supply of motor time spacing, can be cut off, thus improve its stability used.
Described limiting plate becomes 90 degree of flat boards connected to form by two pieces, and junction is provided with axle sleeve, is provided with the keyway with the spline fitted on output shaft in axle sleeve.This structure can reduce the material of limiting plate, thus can effectively reduce total quality and the cost of production of banister.
Described gag lever post is made up of screw bolt and nut, and bolt is passed baffle plate and is fixed on baffle plate by nut.This structure is by making the change of bolt length under the baffle to the adjustment of nuts and bolt, and then the adjustment to restrictor bar rotational angle.
The position-limit mechanism of the banister that the utility model obtains, structure is simple, is driven the rotation of limit switch by the rotation of gear output shaft, positioning bolt nut is utilized to locate, achieve to limit switch rotate spacing, ensure that the adjustable angle of restrictor bar, the limitation that its product is used is less.
Accompanying drawing explanation
Fig. 1 is the structural representation of one of them limit switch of the present utility model when contacting with gag lever post;
Fig. 2 is the structural representation of another limit switch of the present utility model when contacting with gag lever post.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1 and Figure 2, the position-limit mechanism of the banister that the present embodiment describes, it comprises baffle plate 2, limiting plate 4 and limit switch 5, shell 1 inwall that described baffle plate 2 is arranged on banister is positioned at the top of the output shaft 3 of banister, described limiting plate 4 is set on the output shaft 3 of banister, two side angulations that described limiting plate 4 contacts with output shaft 3 are 90 degree, the quantity of described limit switch 5 is two, and is separately positioned on two sides that limiting plate 4 contacts with output shaft 3; The baffle plate 2 of output shaft 3 both sides is provided with gag lever post straight down, and the limit switch 5 when the position of gag lever post and the side of the limiting plate 4 of this side are positioned at horizontal level is corresponding; Described limiting plate 4 becomes 90 degree of flat boards connected to form by two pieces, and junction is provided with axle sleeve, is provided with the keyway with the spline fitted on output shaft 3 in axle sleeve.Described gag lever post is made up of bolt 6 and nut 7, and bolt 6 is passed baffle plate 2 and is fixed on baffle plate 2 by nut 7.
