Connected with right guiding voussoir 12, left guiding voussoir 7 and right guiding voussoir 12 brake voussoir 6 and right braking voussoir 11 1 with left respectively
One it is corresponding be slidably matched, it is left and right braking voussoir top be connected to rope 5.
Further described flexible member is spring.
Further described left guiding voussoir 7 and right guiding voussoir 12 brake voussoir 6 and right braking voussoir with left respectively
11 modes being slidably matched correspondingly are to set inclined slip muscle on guiding voussoir, and its thickness subtracts gradually from top to bottom
Small, the one side being engaged on braking voussoir with being oriented to voussoir is provided with chute, and the runner position is corresponding with sliding muscle, both
Angle of inclination it is identical.
Compared with prior art, the utility model is improved existing elevator safety gear, and its advantage is：In electricity
When ladder occurs dropping or rushed to summit, outside shift mechanism is lifted by governor rope, outside shift mechanism drives the braking of guide rail both sides
Voussoir is moved upwards so that both sides are oriented to the direction movement of voussoir promotion braking voussoir direction guiding rail and it is clamped and realized and rub
Wipe braking, and be arranged on the sliding axle with the shaft shoulder that both sides are oriented on voussoir and voussoir is braked to both sides by spring respectively
Frictional force is automatically adjusted, and realizes gradual braking, the effect to elevator brake process with buffering, and reduction collision is damaged
Lose, improve elevator brake effect, security and stability and service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Mark in accompanying drawing for：1- frames, 2- guide rails, 3- grooves, the left fixed seats of 4-, the right fixed seats of 13-, 5- ropes,
The left braking voussoirs of 6-, the right braking voussoirs of 11-, the left guiding voussoirs of 7-, the right guiding voussoirs of 12-, the left sliding axles of 8-, the right sliding axles of 14-,

Embodiment
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
As shown in figure 1, the elevator in the present embodiment includes frame 1, guide rail 2, groove 3, left fixation with double friction safety pincers
Seat 4, right fixed seat 13, rope 5, left braking voussoir 6, right braking voussoir 11, left guiding voussoir 7, right guiding voussoir 12, left cunning
Moving axis 8, right sliding axle 14, spring 9,10, the wherein middle part of frame 1 are provided with the groove 3 coordinated with guide rail 2；In the both sides of frame
Left fixed seat 4 and right fixed seat 13 are symmetrically fixedly installed, left and right fixed seat is the hollow cavity that front and back walls are provided with through hole,
Left and right sliding axle 8,14 of the middle part provided with the ring-type shaft shoulder runs through left and right fixed seat along axis respectively, before the shaft shoulder and fixed seat
