[0002] When installing the elevator guide rail in the elevator shaft, in order to ensure the perpendicularity of the guide rail, the two sides of the guide rail need to be pressed by the angle code, so that the non-vertical section of the guide rail is pressed to be straight, usually the angle code is fixed on the wall of the elevator shaft or the bracket in the shaft, then the pressing block / plate is screwed on the angle code through the bolt, and the end of the pressing block / plate close to the guide rail presses the guide rail.

[0003] However, the bolt pre-tightening force of this conventional assembly method forms a local pressure at the fixed end (close to the elevator guide rail end) of the pressing block / plate, and the free end (far from the elevator guide rail end) forms a cantilever beam structure without constraint, and the maximum bending moment of the cantilever beam appears at the fixed end, which causes linearly distributed bending stress inside the pressing block / plate, and the free end deflects under the action of the bending moment, and the deflection is too large, which causes the pressing block to tilt obviously, weakening the uniformity of the pressing of the guide rail, and after the pressing block / plate tilts, the contact pressure between the guide rail and the angle code decreases from the bolt side to the free end.

[0004] The existing angle code and pressing plate for the elevator guide rail cause the contact pressure between them to decrease from the center bolt side to the free end, resulting in excessive pressure in the area near the bolt, accelerating material yield or fatigue, and the pressing plate away from the end of the elevator guide rail has a reduced contact area, reducing the anti-slippage ability and easily causing loosening, which causes the positioning stability of the elevator guide rail to be poor, therefore a kind of elevator guide rail angle code is proposed.
