Abstract

The utility model relates to a collision cushioning device, which belongs to safety protection devices for vehicles and elevators. The collision cushioning device is provided with a cylinder liner and a push rod, the left end of the push rod is inserted into the right cavity of the cylinder liner and in slide fit with the right cavity, a plurality of circular cushioning rings are installed in the left cavity of the cylinder liner, positioning rings are mounted among the cushioning rings, a shearing ring is installed in the inner chamber of each positioning ring, the diameter of the push rod is equal to the inside diameter of the positioning ring, the left end part of the cylinder liner is sealed by a cylinder cover, and air outlet holes are formed on the cylinder cover. Due to the use of the multiple-stage cushioning and absorbing structure, the utility model can effectively absorb energy from collision attack on vehicles, elevators and lifters, thereby ensuring the safety of vehicles, elevators, lifters and passengers on board.

Description

Buffer device for collision

Technical field

The utility model relates to the safety protection device field of automobile and elevator, says it is a kind of buffer device for collision in detail.

Background technique

As everyone knows: the automobile collision preventing measure mostly is the bumper that metal or other hard material are housed in automotive front end or rear end, and the bumper 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 lift 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 pressure installation all can not play the huge impact power that effective elimination is fallen and produced because of cab, cause the damage of lift, 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 time of collision, to discharge collision energy, thereby guarantees the safety of passenger and automobile, elevator, lift itself.

The technological scheme that its technical problem that solves the utility model adopts is, be provided with cylinder sleeve and push rod, be slidingly matched in the right cavity of the left end insertion cylinder sleeve of push rod and with right cavity, a plurality of circular buffering rings are housed in the left cavity of cylinder sleeve, positioning ring is installed between the buffering ring, and each positioning ring inner chamber is equipped with a shearing ring, and the diameter of push rod is identical with the internal diameter of positioning ring, the left part of cylinder sleeve is processed with air outlet hole 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 lift bump effectively the time guarantees the safety of automobile, elevator, lift 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. positioning ring, 4. buffering ring, 5. bolt, 6. cylinder sleeve, 7. right cavity, 8. boss, 9. bail wire, 10. push rod, 11. air outlet holes, 12. shearing rings.

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 on the push rod 10 is slidingly matched with right cavity 7, a plurality of circular buffering rings 4 are housed in the left cavity 2 of cylinder sleeve 6, positioning ring 3 is installed between the buffering ring 4, each positioning ring inner chamber is equipped with a shearing ring 12, the positioning 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 positioning ring 3, the left part of cylinder sleeve 6 is processed with air outlet hole 11 through cylinder cap 1 shutoff 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 automobile chassis; or be installed in elevator; the cab bottom of lift; when automobile bumps; or elevator; when lift 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; and promote shearing ring 12 forward with buffering ring 4 cut-outs that are adjacent; continue then to cut off through the next shearing ring 12 next buffering rings 4 of bump and with it forward; if the impact 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 lift are fallen is consumed gradually; in addition; gas in the process of punching in the left cavity 2 can be discharged through air outlet hole 11, so the automobile chassis crossbeam; elevator and lift can not be out of shape, whole automobile; elevator and lift are effectively protected.

Claims

1, a kind of buffer device for collision, be provided with cylinder sleeve and push rod, it is characterized in that: be slidingly matched in the right cavity of the left end insertion cylinder sleeve of push rod and with right cavity, a plurality of circular buffering rings are housed in the left cavity of cylinder sleeve, positioning ring is installed between the buffering ring, and each positioning ring inner chamber is equipped with a shearing ring, and the diameter of push rod is identical with the internal diameter of positioning ring, the left part of cylinder sleeve is processed with air outlet hole through the cylinder cap shutoff on the cylinder cap.
