Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution：A kind of lift car with deceleration defencive function
Buffer unit, including mobile jib 1, extension spring 2, fixing axle 3, connecting rod 4, impact bar 5, silencer cover 6, axle center 7, compressed spring 8,
Dust plug 9, piston 10, reset spring 11, looping pit 12, flowing groove 13 and water inlet pipe 14, the two sides of mobile jib 1 are provided with stretching
Spring 2, and extension spring 2 is fixed to each other by the fixing axle 3 in outside with connecting rod 4, and the top of connecting rod 4 is connected with punching
Bar 5 is hit, while the top of impact bar 5 is provided with silencer cover 6, fixing axle 3 constitutes elastic construction by extension spring 2 and mobile jib 1,
And fixing axle 3 about mobile jib 1 center vertical line be symmetrical arranged there are two, enable the device to by being moved to fixing axle 3
Dynamic, so that the downside of connecting rod 4 be driven to be moved, impact bar 5 constitutes elastic construction by compressed spring 8 and mobile jib 1, and presses
The section shape of contracting spring 8, extension spring 2 and connecting rod 4 is triangle, makes the device while passing through compressed spring 8 and stretching
Spring 2 plays buffer function to impact bar 5, and axle center 7 is located at the middle and lower part of impact bar 5, and the outer surface of upper in axle center 7 is provided with
Compressed spring 8, and the center outer surface in axle center 7 is provided with dust plug 9, and the cross-sectional area of compressed spring 8 is less than under mobile jib 1
Side cross-sectional area, and the inside of mobile jib 1 is engraved structure, enables the device to guarantee that the installation of compressed spring 8 is more stable,
And the flowing of 1 internal liquid of mobile jib can more smoothly, and piston 10 is connected to the bottom in axle center 7, and the lower part of piston 10 connects
It is connected to reset spring 11, and the outside of reset spring 11 offers looping pit 12, while the outside of looping pit 12 is reserved with stream
Dynamic slot 13, piston 10 constitutes lifting structure by reset spring 11 and mobile jib 1, and the range maximum value of piston 10 is upper and lower
The spacing of two looping pits 12 enables the device to the lifting by piston 10, to change the flowing side of 1 internal liquid of mobile jib
Be to the section shape of, looping pit 12 it is trapezoidal, enable the device to the frictional force for increasing liquid flowing, the lower left quarter of flowing groove 13
Water inlet pipe 14 is installed.
Working principle：When using the lift car buffer unit with deceleration defencive function, it is first determined the device
It is whether intact, later can normal use, which is placed into the underface of lift car, is fixed later with ground,
When accident occurs for lift car, when falling downwards, can first be contacted with silencer cover 6, silencer cover 6 can press down on impact later
Bar 5, the compressed spring 8 of 5 lower part of impact bar has certain support force later, during impact bar 5 moves downward, passes through
Fixing axle 3 drives the top of connecting rod 4 to move downward, later because extension spring 2, connecting rod 4 and compressed spring 8 constitute triangle
Shape move the lower end of connecting rod 4 can outward, and extension spring 2 can play an inside layback to the lower end of connecting rod 4 later
Power during impact bar 5 declines, also will drive axle center 7 and move down to play the role of secondary alleviation, Zhi Houhui
Band piston 10 moves down, the movement of piston 10, can squeeze the air of the downside of piston 10, thus to from water inlet pipe 14
The liquid being added is squeezed, and two looping pits 12 that liquid can pass through downside enter the inside of flowing groove 13, Zhi Houyin
It is smaller than entrance for the outlet of looping pit 12, make the frictional force of liquid that can increase sharply, thus slow down the decrease speed in axle center 7,
Play the role of alleviating again, two looping pits 12 that the liquid having more can pass through upside enter the upside of piston 10, work as electricity
After ladder repairs completion, reset spring 11 can be by 10 pushed home of piston, convenient use next time, does not make in detail in this specification
