Arc sliding block 3 is slided to both sides.
Visibly, 63 lower end of three-level buffer body has and three-level buffer body 63 is connected as a single entity structure and in up big and down small reality
The level Four buffer body 64 of heart circular cone stage body shape, and the conical friction face contact of 64 outer circumferential of level Four buffer body and circular cone channel 4.
Level Four buffer body 64 also preferably pushes arc sliding block 3 to slide to both sides while further enhancing cushion effect.
It is apparent that buffer base 1 is in the form of annular discs, the quantity of arc sliding block 3 is four and arc sliding block 3 is to buffer
The center of device pedestal 1 is circumferentially uniformly distributed for the center of circle to be surrounded to form ring structure, and circular cone channel 4 is formed in ring structure.
Further, gliding movement targeting structure 2 includes that the sliding groove 21 on buffer base 1 is arranged in four circumferential directions, is slided
Slot 21 is circumferentially uniformly distributed setting as the center of circle using the center of buffer base 1, and 21 one end of sliding groove extends to buffer bottom
1 center of seat, the other end extend to 1 outer circumferential of buffer base, and 3 bottom of arc sliding block is equipped with and sliding groove 21 is corresponding
Sliding block 22, and sliding block 22 is connected with the mutually sliding of sliding groove 21.Sliding block 22 and sliding groove 21 allow arc sliding block 3 smooth
Sliding, avoid the phenomenon that arc sliding block 3 is not moved without playing buffer function under the extruding of elevator.
It is apparent that horizontal buffer structure 5 includes that several settings are arranged in 1 outer circumferential of buffer base and in vertical direction
Buffing pad 51, buffing pad 51 corresponds on the outside of arc sliding block 3 respectively, and 3 outer circumferential of arc sliding block is equipped with outside
Extend and be in horizontally disposed buffer bar 52, buffing pad 51 is equipped with mounting hole 53 corresponding with buffer bar 52, buffer bar 52
It is arranged in parallel with sliding groove 21, and mounting hole 53 weeks are equipped with linear bearing between 52 outer circumferential of jumper bar of easing up inwardly
56, buffer bar 52 is through in mounting hole 53 and being equipped on buffer bar 52 can make arc sliding block 3 retain towards buffer base 1
The elastic buffer member 54 of center movement trend.
Specifically, elastic buffer member 54 includes the buffer spring 55 that is set on buffer bar 52, and buffer spring 55 1
End is resisted against on buffing pad 51, and the other end acts on 3 outside of arc sliding block.Buffer spring 55 possesses good elasticity, in water
Square play very big buffering effect upwards.
Visibly, the stress end face 7 of first-level buffer body 61 is connected as a single entity structure equipped with several with first-level buffer body 61
Buffering protrusion 71.Carriage is contacted with buffering protrusion 71 actually.
Preferably, plating is equipped with damping layer 41, and the outer circumferential of three-level buffer body 63 and damping layer 41 on conical friction face
It is in contact, and 63 upper end of three-level buffer body is without departing from the outside of 4 upper end of circular cone channel.41 damping noise reduction of damping layer and anti-flammability are very
It is good, very big effect is also played in terms of buffering effect.
The principle of the present embodiment is: when lift car, which falls, is depressed into buffer, carriage can connect with multi-buffer component 6
Touching, i.e., carriage can press against the buffering protrusion 71 on the first-level buffer body 61 of the top, and first-level buffer body 61 can squeeze level 2 buffering
Body 62, level 2 buffering body 62 squeeze three-level buffer body 63 and level Four buffer body 64 again, due to the gravity of carriage, three-level buffer body 63
Moving down extruding arc sliding block 3 with level Four buffer body 64 follows sliding block 22 to move in sliding groove 21 to both sides, this process
In, pressure and vibration on inclined direction are slowed down between multi-buffer component 6 and with the inclined contact surface of arc sliding block 3,
Damping layer 41 is rubbed and damping noise reduction, and buffer bar 52 is moved to both sides makes buffer spring 55 shrink damping decompression.
