Embodiment
Fig. 1-Fig. 2 is please referred to, in a first aspect, the embodiment of the present application provides a kind of Self-resetting shock isolating pedestal 101, including first
Support 110, the second support 120 and sliding shoe 130.The top surface of first support 110 is recessed with the first sliding groove 111, the second support
120 bottom surface is recessed with the second sliding groove 121, and sliding shoe 130 is sliding for being slidably received in the first sliding groove 111 and second
Between dynamic slot 121.
Referring to Fig. 3, in embodiments herein, the first sliding groove 111 be cup depth from the center to its
The arc groove that circumferential edge is gradually reduced, that is, refer to, the first sliding groove 111 is the curved slot arrangement of similar spherical cap.It is sliding
It, can be under gravity after motion block 130 is slided between the first sliding groove 111 and the second sliding groove 121 by shock effect
It returns at the center of the first sliding groove 111, realizes automatically reseting for sliding shoe 130.
Fig. 4-Fig. 5 is please referred to, illustratively, the bottom of sliding shoe 130 is provided with for being bonded with the first sliding groove 111
First protrusion, when so that sliding shoe 130 sliding in the first sliding groove 111, the bottom of sliding shoe 130 can be preferably with
The state of one sliding groove, 111 retaining surface fitting, contacts that good, stress is equal between the bottom of sliding shoe 130 and the first sliding groove 111
It is even, load performance is good, while sliding shoe 130 also being enabled more steadily to slide in the first sliding groove 111.
Referring to Fig. 6, in some optional embodiments, the second sliding groove 121 be cup depth from the center to
Its arc groove being gradually reduced in circumferential edge refers to that the second sliding groove 121 is similarly the arc groove of similar spherical cap
Structure.After sliding shoe 130 is slided between the first sliding groove 111 and the second sliding groove 121 by shock effect, the second sliding groove
121 above-mentioned arc setting can promote sliding shoe 130 to return at the center of the second sliding groove 121, be conducive to improve sliding shoe
130 effects to automatically reset.Second sliding groove 121 and the first sliding groove 111 constitute double pendulum structure, so that isolating affection is also more
It is good.
Illustratively, when the second sliding groove 121 is set as the arc groove of above-mentioned form, the top of sliding shoe 130 is arranged
There is the second protrusion for being bonded with the second sliding groove 121, it is sliding when so that sliding shoe 130 sliding in the first sliding groove 111
The state that the top of motion block 130 equally can be preferably bonded with 121 retaining surface of the second sliding groove, the top of sliding shoe 130 and
It is good that good, uniform force, load performance are contacted between second sliding groove 121, while also making sliding shoe 130 in the first sliding groove
The stability slided in 111 is further enhanced.
It is understood that the second sliding groove 121 needs be only configured to opposite with the top of sliding shoe 130 to slide
, in other embodiments, the second sliding groove 121 is for example set as the constant flat-bottom slot of cup depth, at this time sliding shoe
130 top is optionally also configured as planar structure, so that the top of working condition downslide motion block 130 can be with the second sliding groove
121 keep preferable face paste conjunction state.
Further, the recess radian of the first sliding groove 111 is greater than the recess radian of the second sliding groove 121, the i.e. arc
Slot from the center to it on the direction of circumferential edge, such as along the first preset direction and on the second preset direction,
The variation degree of first cup depth in unit distance of sliding groove 111 is greater than the second sliding groove 121 and is recessed in unit distance
The variation degree of depth.The recess radian of second protrusion is bigger, so that the sliding shoe 130 and second in sliding of sliding shoe 130
Relative displacement is bigger in the vertical direction for sliding groove 121, and relative motion is more unstable.Such as when sliding shoe 130 is provided with first
When protrusion and the second protrusion, the recess radian of the second sliding groove 121 is bigger, sliding shoe 130 be more intended on the whole it is spherical,
Sliding shoe 130 is caused to be easy to roll between the first sliding groove 111 and the second sliding groove 121.The recess arc of second sliding groove 121
The set-up mode for spending the recess radian less than the first sliding groove 111, avoids the radian of the second sliding groove 121 excessive and influences sliding
The stability that block 130 slides between the first sliding groove 111 and the second sliding groove 121.
In embodiments herein, optionally, the first sliding groove 111 is set as the concave shape of arc groove, sliding shoe
130 are provided with convex shape when the first protrusion, and the second sliding groove 121 is set as concave shape when arc groove, sliding shoe
130 are provided with convex shape when the second protrusion, are in the corresponding curve shape of even curvilinear equation, such as 2 equation of n th order n, 4
Equation of n th order n, 6 equation of n th order n etc..Even equation curve is more convenient in structural dynamical model, can be more convenient according to demand, quasi-
It really determines curvilinear equation appropriate, guarantees the stability of work.
Sliding shoe 130 includes two first sides 131 being oppositely arranged on the first preset direction, and the first preset direction is
Refer to direction shown in arrow a in Fig. 1 and Fig. 2, so that sliding shoe 130 is by shock effect in the first sliding groove 111 and the second sliding
It can be slided along the first preset direction when being slided between slot 121.Sliding shoe 130 further includes being oppositely arranged on the second preset direction
Two second sides 132, the second preset direction refers to direction shown in arrow b in Fig. 1 and Fig. 2, so that sliding shoe 130 is shaken
Movement is used in when sliding between the first sliding groove 111 and the second sliding groove 121 and can slide along the second preset direction.It is understood that
, the first preset direction and the second preset direction refer to two different directions of intersection, the first preset direction and second pre-
Set direction non-parallel relation nor collinear relationship.
