Abstract
The utility model discloses a kind of damping device preventing man-made further destroy, comprise buffering sleeve 1, damping spring 2 and telescopically are arranged on the load-bearing stopper rod (3) in buffering sleeve (1), damping spring (2) is placed in and rushes in sleeve, its one end and load-bearing stopper rod are abutted against, it is characterized in that, one end of described load-bearing stopper rod (3) has boss (4), and boss is socketed in dynamic cooperation with buffering sleeve; Boss has the inner (9) on arcuation outer end (8) and straight edge; The inwall of described buffering sleeve is provided with spring pin (5); Buffering sleeve is provided with for stopping in when stretching out state the soft sleeve (6) that spring pin stretches out at load-bearing stopper rod; The end of described buffering sleeve has the spiral cover (7) that can take off.The man-made further destroy that the utility model can avoid damping device to produce in reseting procedure after clashing into generation, and have reusable, advantage easy for installation.
Description
Technical field
The utility model relates to the reusable damping device preventing large-scale utensil from clashing into.
Background technique
Crashproof facility at present for many large-scale utensils such as automobile, locomotive only slows down collision, the injury that the secondary collision after not considering to collide causes, and often there is the situation of man-made further destroy.
The content of model utility
In view of the deficiencies in the prior art, the purpose of this utility model is just to provide a kind of damping device preventing man-made further destroy, makes it man-made further destroy damping device being avoided to produce in reseting procedure after clashing into generation.
The means that the utility model reaches its object are:
A kind of damping device preventing man-made further destroy, comprise buffering sleeve 1, damping spring 2 and telescopically are arranged on the load-bearing stopper rod 3 on buffering sleeve 1, damping spring 2 is placed in and rushes in sleeve, its one end and load-bearing stopper rod 3 are abutted against, it is characterized in that, one end of described load-bearing stopper rod 3 has boss 4, and boss is socketed in dynamic cooperation with buffering sleeve 1; Boss has the inner 9 on arcuation outer end 8 and straight edge; The inwall of described buffering sleeve 1 is provided with spring pin 5; Buffering sleeve 1 is provided with for stopping in when stretching out state the soft sleeve 6 that spring pin stretches out at load-bearing stopper rod; The end of described buffering sleeve has the spiral cover 7 that can take off.
When shock does not occur, damping spring 2 and load-bearing stopper rod 3 stretch out naturally, and soft sleeve 6 blocks stretching out of spring pin 5; Clash into the instantaneous of generation, load-bearing stopper rod 3 and damping spring 2 are compressed by buffering sleeve 1, during certain position in compression process, soft sleeve 6 is destroyed, stretching out of spring pin 5, what the spring pin stretched out blocked the boss 4 of load-bearing stopper rod directly causes secondary pulse to destroy along inner 9 to stop that load-bearing stopper rod 3 acts on stretching next time at damping spring 2.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model embodiment stretches out state;
Fig. 2 is the structural representation of the utility model embodiment compressive state;
Fig. 3 is the A portion enlarged view of Fig. 1;
Fig. 4 is the B portion enlarged view of Fig. 2.
Embodiment
Composition graphs 1-4 can see, the utility model can prevent the damping device of man-made further destroy from comprising buffering sleeve 1, and damping spring 2 and telescopically are arranged on the load-bearing stopper rod 3 on buffering sleeve 1.Damping spring 2 is placed in buffering sleeve, and the boss end with load-bearing stopper rod 3 is withstood in one end of damping spring, and the external diameter of boss 4 is greater than load-bearing stopper rod 3 external diameter, and boss 4 stretches in buffering sleeve 1 and coordinates in dynamic with the internal face of buffering sleeve; The inwall radial direction of buffering sleeve 1 is provided with spring pin 5; Spring pin 5 is short range structure, and its spring function can be provided by metal or rubber and analog.Buffering sleeve 1 be provided with at load-bearing stopper rod in stopping when stretching out state that the soft sleeve 6 that spring pin stretches out, this soft sleeve can be aluminum tubular film (aluminium foil) or form; The end of described buffering sleeve has the spiral cover 7 that can take off.
As shown in figures 1 and 3, the utility model is when stretching out state, and soft sleeve 6 stops the stretching, extension of spring pin 5; But bearing shock in a flash, load-bearing stopper rod bounces back, its boss is by destroying soft sleeve during spring pin 5, the situation that spring pin 5 stretches pie graph 2 and Fig. 4 now spring pin 5 blocks the inner 9 on the straight edge of boss, block the reply impulse force that damping spring 2 pairs of load-bearing stopper rods are possible, avoid the generation of secondary damage.
Of the present utility model recovery uses the spiral cover 7 by unloading buffering sleeve ends to realize, and after unloading screwed lid, reset buffering spring again, can drop into new use after resetting soft sleeve.
When reality is implemented, spring pin 5 can be set up along the axial different depth many places of buffering sleeve in buffering sleeve 1.
Claims (3)
1. one kind can prevent the damping device of man-made further destroy, comprise buffering sleeve (1), damping spring (2) and telescopically are arranged on the load-bearing stopper rod (3) in buffering sleeve (1), damping spring (2) is placed in and rushes in sleeve, its one end and load-bearing stopper rod are abutted against, it is characterized in that, one end of described load-bearing stopper rod (3) has boss (4), and boss is socketed in dynamic cooperation with buffering sleeve; Boss has the inner (9) on arcuation outer end (8) and straight edge; The inwall of described buffering sleeve is provided with spring pin (5); Buffering sleeve is provided with for stopping in when stretching out state the soft sleeve (6) that spring pin stretches out at load-bearing stopper rod; The end of described buffering sleeve has the spiral cover (7) that can take off.
2. the damping device preventing man-made further destroy according to claim 1, is characterized in that, described spring pin (5) is set up along the axial different depth many places of buffering sleeve in buffering sleeve (1).
3. the damping device preventing man-made further destroy according to claim 1, is characterized in that, described soft sleeve (6) is aluminum tubular film.
