Meshed gears 9, and there are two the vortexs being limited on the horizontal interior wall 7 for the directly fixation of the upper and lower two sides of the gear 9
Spring 10, the gear 9 and volute spring 10 are fixed on the steel plate 3 for having rack gear by the support frame by stretching out on the horizontal interior wall
Corresponding thereto and between the inner wall of parallel constraint outer sleeve 6, the support frame, including two be fixed on it is described it is parallel in
The crossbearer 11 of wall is located at the top and one of two volute springs 10 through crossbearer 11, volute spring 10 and gear 9
Vertical pivot 12, the volute spring 10 are limited in 7 on the horizontal interior wall by limit card slot 13.Above scheme is interior to consume energy as a result,
Core is center line, and gear, volute spring, the rack gear of two sides are respectively symmetrical installation, central symmetry setting, so that two vortexs
The reaction force of plane is more consistent, for distortion correction and the equal better effect of vortex plane energy consumption.In this embodiment
In, nearby space all has the possibility for installing gear spring to entire energy consumption inner core, however, in practice, it has been found that lean on
The initial position of nearly load transmission, and correspond to the end position of position in fact, i.e. space near two terminals of energy consumption inner core,
Twisted planar is formed using volute spring, needs the correction demand to energy consumption inner core stronger, also, grasp two positions,
It can start to correct in source, not make displacement transfer as far as possible, so as to further decrease the section of deformation, inhibit deformation
Ability is stronger, thus we select using junction steel plate as inner core both ends, and the mode shape of rack gear is installed on junction steel plate
At above scheme.
Further, in general, energy consumption inner core is understood some and is in outside constraint outer sleeve, should be partially due to straight
Exposed unfettered and support is connect, the energy consumption inner core compared inside constraint outer sleeve is more weak, easily destroys.It uses
Steel plate, rack gear, is combined with the limit of volute spring gear, the exposed part in constraint outer sleeve, using in steel plate substitution energy consumption
Core, and the mode being bolted to connection will have the steel plate and Interal fixation of rack gear, to rack gear be fixed, although should
Part is not covered by energy consumption inner core, but also enhances the intensity of the exposed part to a certain extent；Volute spring to consume
The displacement of the lines of energy inner core is changed into angular displacement, also, it is in end nearby (being close to exposed sheet steel sections), so that
Volute spring, meshed gears and the rack gear of limit and support frame can form frame in the exposed steel plate, have certain
Supporting role, and the twisting resistance by volute spring greatly reduce the exposed part and act in load on the basis of support

In inevitably damage, influence the service life；Secondly marmem recoverable strain value is very big, and ordinary metallic material is difficult
With realization；Finally, due to which Ovshinsky bulk modulus is greater than geneva bulk modulus, shape memory alloy elastic modulus is with temperature
It increases and increases (opposite with common metal), this makes it still keep high elastic modulus at relatively high temperatures.Therefore, remembered using shape
Recall the spring section that alloy can be fabricated to the device.
Under geological process, energy consumption inner core is by the load come from building transmitting, and energy consumption inner core is deformed, one
In load range, energy consumption inner core deformation causes its two side gear to engage with the rack gear on steel plate, deform make gear band carry-over bar to
Energy consumption inner core deformation opposite direction movement, so that shape and position time when energy consumption inner core connect with gear is to nature
It is multiple；When being more than the load range (restoring force of gear can not reply energy consumption inner core), it is fixed on the upper and lower two sides of gear
Volute spring causes deformation by the deformation of energy consumption inner core and planar generates torque, and volute spring is limited in horizontal interior wall
On, the restoring force that volute spring generates moves gear band carry-over bar to energy consumption inner core deformation opposite direction, so that and gear
Shape and position when the energy consumption inner core of connection is to nature are replied.
As a result, disclosure main purpose be in order to mitigate vibration to structure function, for the design of the anti-buckling support of tradition,
A kind of device of Self-resetting is provided, the impaired of inner core is slowed down.In the case of seismic events, enabling capabilities are improved.It is made into vortex bullet
Spring is added in gear, and anti-buckling support energy consumption inner core, gear, volute spring, outer sleeve upper limit card are worked together,
The displacement of the lines integrally generated is converted into angular displacement, and it slows down the impaired of inner core with certain runback bit function.Gear solution
Certainly spring corner is too small is not able to satisfy inner core route problem.
Volute spring deforms material torque, generation elasticity of flexure deformation by bending after square, thus spring is flat at itself
Face generates torsion.The size and torque of its deformation angle are directly proportional, have high torsion, with the twisting resistance of multi-angle away from thus apply to grow
