Abstract
The utility model discloses a car buffering chassis, including support, buffer and locking device, a plurality of buffer are installed to the support bottom, and buffer is located locking device's inside, and buffer includes piston rod and spring, and the spring mounting is on the piston rod, and locking device includes latch fitting, fastener and trip, and the latch fitting is located the piston rod outside, and the latch fitting is connected bottom the support, and the trip is installed on the lateral wall of fastener, and the bottom at the piston rod is installed to the fastener. The utility model discloses a buffer and the locking device cooperation of support bottom reach the mesh that prevents the elevator from to fall the back secondary rebounds to cause the injury to the passenger in the elevator once more after avoiding the elevator to fall, the utility model has the advantages of simple structure easily promotes.
Description
Technical field
The utility model is related to elevators field, and more particularly to a kind of car buffers chassis.
Background technology
Lift car is mounted in elevator, after lift car breaks down to fall, traditional lift car intelligence
Can be slowed down by the buffer of elevator bottom, but buffer after falling it is also possible to rebound, it is extremely easy right
Passenger in lift car produces secondary injury, accordingly, it would be desirable to a kind of buffering chassis that can prevent car from rebounding.
The content of the invention
The purpose of this utility model is to provide a kind of car that can prevent car from rebounding buffering chassis.
The purpose of this utility model is achieved through the following technical solutions：
A kind of car buffers chassis, including support, buffer unit and locking device, and frame bottom is provided with multiple buffering dresses
Put, and buffer unit is located at the inside of locking device, buffer unit includes piston rod and spring, and spring is installed on the piston rod,
Locking device includes latch fitting, fastener and snap fit, and latch fitting is located at piston rod outside, and latch fitting is connected with frame bottom, and fastener is installed
In the bottom of piston rod, snap fit is arranged on the side wall of fastener.
Snap fit groove is provided with the latch fitting.
The utility model is coordinated by the buffer unit and locking device of frame bottom, and reaching prevents secondary after used during elevator falling
The purpose of bounce-back, so as to avoid used during elevator falling after the passenger in elevator is damaged again, the utility model have structure letter
It is single, it is easy to the advantages of promoting.
Description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 uses schematic diagram for the utility model.
Reference：1- supports, 2- buffer units, 21- piston rods, 22- springs, 3- locking devices, 31- latch fittings, 32- are buckled
Part, 33- snap fit grooves, 34- snap fits.
Specific embodiment
As shown in figure 1, the utility model includes support 1, buffer unit 2 and locking device 3, the bottom of support 1 is provided with
Multiple buffer units 2, and buffer unit 2 is located at the inside of locking device 3, buffer unit 2 includes piston rod 21 and spring 22, bullet
Spring 22 is arranged on piston rod 21, and locking device 3 includes latch fitting 31, fastener 32, snap fit groove 33 and snap fit 34, and latch fitting 31 is located at lives
The outside of stopper rod 21, and latch fitting 31 is connected with the bottom of support 1, and snap fit groove 33 is provided with latch fitting 31, fastener 32 is arranged on piston
The bottom of bar 21, snap fit 34 is arranged on the side wall of fastener 32.
Operation principle of the present utility model is：When used during elevator falling is to elevator bottom, piston rod 21 is with spring 22 by certainly
The elastic force of body, makes elevator have the process of a continued deceleration, the snap fit 34 when extreme position is dropped to elevator, on fastener 32
Moment is snapped in the snap fit groove 33 on latch fitting 31, piston rod 21 is no longer ejected with spring 22, and so as to reach elevator bounce-back is prevented
Purpose, be effectively protected the safety of passenger in elevator.
The utility model is carried out for embodiment or embodiment to the purpose of this utility model, technical scheme and advantage
Further describe, should be understood that embodiment provided above or embodiment are only of the present utility model preferred
Embodiment is all new to this practicality within spirit of the present utility model and principle not to limit the utility model
Any modification, equivalent substitution and improvements that type is made etc., should be included within protection domain of the present utility model.
