Abstract
The utility model relates to a collision bumping device, which belongs to the safety protection devices of automobiles and lifts. The device is provided with a cylinder sleeve and a push rod, wherein the left end of the push rod is inserted into the right cavity of the cylinder sleeve and is in slide fit with the right cavity; a plurality of circular buffer rings are arranged in the left cavity of the cylinder sleeve; a positioning ring is arranged between the buffer rings; the diameter of the push rod is the same with the inner radius of the positioning ring; the left end of the cylinder sleeve is blocked by the cylinder cover; and the cylinder cover is processed with air outlet holes. As the multi-stage buffer absorbing structure is adopted, the utility model can effectively absorb the energy which is generated by the automobile, lift and elevator during collision, and ensure the safety of the automobile, lift, elevator and the passenger.
Description
Technical field
The utility model relates to the safety guard field of automobile and elevator, says it is a kind of buffer device for collision in detail.
Background technology
As everyone knows: the automobile collision preventing measure mostly is the bumper/spoiler that metal or other hard material are housed in automotive front end or rear end, and the bumper/spoiler of this metalloid or hard material is rigid components, when automobile bumps, can not play and eliminate the huge impact power that produces because of collision effectively, can not prevent to collide the accident of the car crash that causes to greatest extent because of traffic accident.Elevator and elevator are when falling downwards because of accident, produce lot of energy, and the impact energy that elevator and elevator cab can bear is limited, existing spring and hydraulic efficiency gear all can not play the huge impact power that effective elimination is fallen and produced because of cab, cause the damage of elevator, elevator cage and personnel's injury.
Summary of the invention
The purpose of this utility model just is, in order to overcome the deficiencies in the prior art, and provides a kind of buffer device for collision, prolonging collision time, to discharge collision energy, thereby guarantees the safety of passenger and automobile, elevator, elevator itself.
The technical scheme that its technical matters that solves the utility model adopts is, be provided with cylinder sleeve and push rod, the left end of push rod insert in the right cavity of cylinder sleeve and with right cavity bearing fit, a plurality of circular buffering rings are housed in the left cavity of cylinder sleeve, steady ring is installed between the buffering ring, the diameter of push rod is identical with the internal diameter of steady ring, and the left part of cylinder sleeve is processed with air gate through the cylinder cap shutoff on the cylinder cap.
The effect that the utility model is useful is, because of adopting the multi-buffer absorbing structure, thereby the energy can absorb automobile, elevator and elevator bump effectively the time guarantees the safety of automobile, elevator, elevator and passenger.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. cylinder caps among the figure, 2. left cavity, 3. steady ring, 4. buffering ring, 5. bolt, 6. cylinder sleeve, 7. right cavity, 8. boss, 9. bail wire, 10. push rod, 11. air gates.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
As shown in Figure 1, be provided with cylinder sleeve 1 and push rod 10, the left end of cylindrical push rod 10 inserts in the right cavity 7 of cylinder sleeve 6, round ring boss 8 and right cavity 7 bearing fits on the push rod 10, a plurality of circular buffering rings 4 are housed in the left cavity 2 of cylinder sleeve 6, steady ring 3 is installed between the buffering ring 4, the steady ring 3 of low order end is fixed on the cylinder sleeve 6 through bolt 5, the diameter of push rod 10 is identical with the internal diameter of steady ring 3, the left part of cylinder sleeve 6 is through cylinder cap 1 shutoff, be processed with air gate 11 on the cylinder cap 1, be set with bail wire 9 on the push rod 10 of cylinder sleeve 6 right-hand members.
During use the utility model buffer device for collision is installed in the crossbeam front end or the rear end of car chassis; or be installed in elevator; the cab bottom of elevator; when automobile bumps; or elevator; when elevator falls; because of the effect of impacting; push rod 10 moves forward; the left end of push rod 10 at first cuts off the buffering ring 4 of low order end; continue then to clash into next buffering ring 4 forward and it is cut off; if the impulsive force during automobile impacting is enough big; the buffering ring 4 of right-to-left is punched successively; thereby the impact energy when automobile impacting or elevator and elevator are fallen is consumed gradually, and in addition, the gas in the process of punching in the left cavity 2 can be discharged through air gate 11; so car chassis crossbeam; elevator and elevator can not be out of shape, whole automobile; elevator and elevator are effectively protected.
Claims (1)
