It can also uses several linear spiral springs with several corresponding annular tubes in side by side arrangement, made by linear spiral spring and annular tubes with various diameters and coaxial sleeves in the shape of L, Z, U or T. It can be used in all kinds of occasions for the change of force delivery action.
Description
The present invention relates to a kind of novel helical spring that can change the direction of transfer of power.
Spring has been penetrated into our production and life, and industrial production and daily life are all closely related with spring.Though the kind of spring has much now, these springs particularly straight line type helical spring can only transmit suffered power to a direction.Like this when much needing the direction of transfer of change power, particularly have destructive masterpiece and be used for launch vehicle for some, when bumping between the traffic tool, elevator out of control when high building falls downwards etc. a lot of situations all need to change the direction of transfer of power, at this moment we will feel simply helpless.
As everyone knows, present widely used straight line type helical spring has the excellent absorbing vibration power and the effect of impact force, but the linear helical spring of this class, generally be as weight press it or have external impacts it the time, this spring absorption pressure or impact force spring are compressed, but the non-direct force side of spring will be subjected to the power that passes over along compressed spring equally.Destroy and personnel in object are not had the direction of injury if the pressure that the straight line type helical spring can be subjected to or impact force absorb and be delivered to object do not had, so just can will drop to minimum even be zero to the destructiveness of objects such as launch vehicle, facility with to the extent of injury of personnel in this object under collision between the traffic tool, elevator a lot of situations such as fall out of control.
The objective of the invention is to provide a kind of direction of transfer that can change power, can efficient absorption and discharge a kind of novel helical spring of various striking forces and shaking force.
The object of the present invention is achieved like this:
Put sleeve pipe in the helical spring outside of straight line type, the straight line type helical spring is made the novel helical spring of the direction of transfer that can change power of shapes such as L shaped, Z-shaped, U-shaped or T shape with sleeve pipe, wherein the length of an end sleeve pipe is less than the length of this end sleeve pipe internal spiral spring, promptly there is the helical spring of an end will stretch out outer one section of sleeve pipe, so that the helical spring of this end can be accepted external active force, we are referred to as the force side this end, and we are referred to as force releasing end the other end.Force releasing end can be sealing or nonocclusive, and sealing surface is the force releasing end face during sealing, and can to have the diameter of a bit of sleeve pipe to be shrunk to smaller than the diameter of remaining part sleeve pipe for this end during non-sealing, also corresponding the dwindling of diameter of this section minor diameter sleeve pipe internal spiral spring.Sealing and the purpose of dwindling this a part of casing diameter are to make helical spring that the helical spring of opposite side force side is set back.When the force side was subjected to external active force, this power just helical spring in the sleeve pipe was delivered to force releasing end, and then discharges active force.
When adopting the structure of many straight line type helical springs and Duo Gen sleeve pipe, the straight line type helical spring of many sleeve pipes and Qi Nei can adopt the structure that is arranged side by side, and also can be that sleeve pipe with the straight line type helical spring of many different-diameters and different-diameter adopts the concentric suit to make the novel helical spring of the direction of transfer that can change power of shapes such as L shaped, Z-shaped, U-shaped or T shape.
The present invention also can be the outside that the straight line type helical spring is enclosed within rod, the straight line type helical spring is made the novel helical spring of the direction of transfer that can change power of shapes such as L shaped, Z-shaped or U-shaped with the cover rod, wherein the length of end cover rod is less than the length that this end overlaps excellent external spiral spring, promptly there is the helical spring of an end will stretch out outer one section of cover rod, so that the helical spring of this end can be accepted external active force, we are referred to as the force side this end, and we are referred to as force releasing end the other end.Force releasing end can be established the resetting block of a bit of diameter greater than the helical spring diameter.The purpose that resetting block is set is so that helical spring can make the helical spring of opposite side force side set back after external force is withdrawn from.When the force side was subjected to external active force, this power just helical spring outside the cover rod was delivered to force releasing end, and then discharges active force.
Can adopt to satisfy at said method middle sleeve and cover rod and use desired intensity and flexible metallic material or composite and make.
Special what propose is when adopting the U-shaped structure, and the helical spring of two stud end of U-shaped also can all stretch out outer one section of sleeve pipe or cover rod, promptly all is the force side.
In actual applications, the force side also can be fixed by the helical spring of mode such as bonding, welding and force side with the equal-sized dull and stereotyped stress surface of force side spring section area one, to better meet the practical application needs.The fixedly ear that this novel helical spring and various launch vehicle, bridge, sports shoes etc. can be fixed is arranged on the rod at sleeve pipe or cover.
The present invention can be widely used in all various objects, facility or the occasions that need absorb and change the direction of transfer of power, as: damping of various energy-absorbing vehicle bodies, chassis, bumper, elevator melt pit, bridge, vehicle seat, sports shoes or the like.
That the present invention has is simple in structure, easy for installation, with low cost, absorb and discharge force efficiency height such as collision and vibrations and effect remarkable, the characteristics that can have the power of destruction to absorb to objects such as launch vehicle, bridge, facility the overwhelming majority and discharge to the direction of object and facility not being had destruction, personnel and do not have injury.
