Specific embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
Such as the elevator car safety that a kind of Fig. 1~band shown in Fig. 2 buffers, including guide rail 1 and car 2, car 2 is in guide rail
Lifting is slided on 1, it is characterised in that：Locker 3 is equipped between the guide rail 1 and car 2, several lockings are equipped on guide rail
Position when elongated slot 11, locking 11 position of elongated slot and locker 3 rest on each layer is corresponding, and locker 3, which has, to be locked
Lock the first state of elongated slot 11 and car 2 and the second state of unlock locking elongated slot 11 and car 2, the locker 3 and
Equipped with for slowing down the buffer unit 4 of the impact force generated when car drops between car 2, because the reason for being elongated slot, latch
There is device 3 time enough can be inserted into advance in locking elongated slot 11, increases its accuracy rate, and with buffer unit 4, can protect
Shield locker is hardly damaged it.
As preference, the buffer unit 4 includes fixed block 41, guide rod 42, elastic component 43 and limited block 44, it is described solid
Determine block 41 and be fixedly connected with car 2,42 one end of guide rod is fixedly connected with fixed block 41, and the other end is fixedly connected with limited block 44, lock
Device 3 is arranged between fixed block 41 and limited block 44 and is slidably connected with guide rod 42, and elastic component 43 is arranged on 3 He of locker
Between fixed block 41, in the elevator emergency stopping time, locker 3 is locked with guide rail 1, and car 2 is because of the distance and the weight of itself fallen
Continue to move down, be sprung back after the buffering of elastic component 43, alleviate the stress of locker 3 and ensure that personnel in car 2
Safety.
As preference, the elastic component 43 is the elastic components such as spring or elastic rubber, but the durability degree of spring
It is more preferable than other elastic components in the case of long-term use with deformation extent.
As preference, the locker 3 includes mounting base 31,31 both ends of mounting base are equipped with positioning pin 32 and driving member
Part 33, mounting base 31 are slidably connected with buffer unit 4, the driving element 33 drive the insertion of positioning pin 32 locking elongated slot 11 or
Extraction departs from locking elongated slot 11, can make the uniform force when bearing to come impact force of locker 3.
As preference, the positioning pin 32 and 1 corresponding one end of guide rail are equipped with ball, the guiding direction of bowl with
Guide rail 1 corresponds to and is close to guide rail 1, and when car 2 falls positioning pin 32 can be more easily inserted in locking elongated slot 11.
As preference, the driving element 33 is electric pushrod or cylinder.
As preference, the locker 3 is separately mounted to the top and bottom of car 2, and on one side
3 sequence of a pair of catches device, guide rail is equipped with corresponding locking elongated slot 11, increases stress point, and ensure that car is fallen
