Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
As shown in fig. 1-4, a safety handle in an elevator car comprises a car 1, wherein a handle groove 2 and two cavities 3 are formed in the side wall of the car 1, the two cavities 3 are symmetrically arranged on the two sides of the handle groove 2, a handle 4 is arranged in the handle groove 2, the handle 4 is in an inverted U shape, rotary elastic mechanisms are respectively arranged in the cavities 3, and the rotary elastic mechanisms are connected with the bottom ends of the handle 4;
rotatory elastic mechanism is including horizontal pole 5, horizontal pole 5 runs through the lateral wall of handrail groove 2, the one end of horizontal pole 5 and the bottom end-to-end connection of handrail 4, the other end of horizontal pole 5 is connected with atress piece 6, the cover is equipped with torsional spring 7 on horizontal pole 5, the one end of torsional spring 7 and the lateral wall fixed connection of cavity 3, the other end and the one side of atress piece 6 of torsional spring 7 are connected.
The cross rod 5 is fixedly connected with the side wall of the handrail groove 2 through a bearing 8.
The other side of the stress block 6 is bonded with sponge and is in contact fit with the side wall of the cavity 3, so that the handrail 4 is prevented from colliding with the side wall of the handrail groove 2 when being elastically recovered by the torsion spring 7.
The outer department of bottom still is provided with bearing seat 9 in handrail groove 2, be provided with a pair of support thing recess 10 on the bearing seat 9, support thing recess 10 and handrail 4 adaptation to the radian that handrail 4 pulled out has been restricted.
The middle part of the handrail 4 is sleeved with a handle sleeve 11, which is convenient for the hands to grasp.
