The gimbal isolation device 1 comprises a lower seat 4, a upper seat 5 and a spherical body 6. Between the upper and lower seats 45, the lower seat 4 has a first concave surface 7'. The upper seat 5 has: a point contact with the first side of the Wei 1st surface 7 and a second concave surface 8 The highest point F' is when the earthquake occurs to cause the ground 3 to vibrate horizontally. 'This: the seat 4 drives the ball 6 to roll repeatedly between the upper and lower seats 4, 5' and by the upper and lower seats 4 The relative movement of 5 prevents the building 2 from vibrating with the ground 3, and achieves the effect of isolation. However, the ball 6 will leave the lowest point 该 of the first concave surface 7 and the highest profit of the second concave surface 8 when rolling, so that the upper and lower seats 4 are hanged 2 and 2 are lifted up, in other words, the conventional isolation device Therefore, how to carry out the structure of the universal isolation device 3 = : to achieve better isolation effect, has become an industry waiting for = [Summary] The main purpose of the present invention is to provide a kind of universal in view of the above-mentioned shortcomings, 4 1308187 == price; the vibration of the horizontal direction, the smaller vertical 兮^ has a lower seat, a seat, an umbrella and a sphere. The umbrella system is located between the upper and lower seats, and The point contact is in contact with the upper seat, and the ball system is disposed between the umbrella body and the lower seat, and is in contact with the umbrella body and the lower seat in a point contact manner, when the earthquake occurs, the sphere and The light body can roll and oscillate back and forth between the upper and lower seats respectively, so that the universal spacer can not only vibrate in the horizontal direction, but at the expense of a small vertical vibration. BRIEF DESCRIPTION OF THE DRAWINGS In order to better understand the structure and features of the present invention, a preferred embodiment and the accompanying drawings are as follows, wherein: 15 is a side view of a preferred embodiment of the present invention; 1 is a cross-sectional view of a first preferred embodiment of the present invention; the fourth diagram is similar to the third diagram, but shows an active state: Please refer to the second to third figures, the universal direction provided by the preferred embodiment of the present invention The vibration isolation device 2 is embedded in a structure 22 and the ground 24. The isolation device 20 includes a lower seat 3, a tens of thousands, and a sphere 60. Captain 40, - Umbrella 5. The lower seat 3 is disposed on the floor 24, and has a top end concave surface 32, and the second concave surface 32 is spherical and has a lowest point a. Zhuoyi The upper seat 40 is disposed on the bottom side of the structure 22, and the bottom end of the upper cymbal 40 forms 20 l3 〇 8l87 and a second concave surface 42. 5 10 15 The umbrella body 50 is disposed between the upper and lower seats 3〇, 4〇, and has a convex surface 52′ on the top side of the upper side. The convex surface 52 is a spherical surface and the highest point thereof The two concave surfaces 42 are connected to each other, and the bottom side of the umbrella body 50 forms a third four surface 54'. The third concave surface 54 is a spherical surface and has a highest point c, wherein the curvature of the first convex surface 52 is greater than the The curvature of the third concave surface 54 is such that the thickness of the umbrella body 50 is the largest at the center (i.e., at point B or c) and gradually decreases toward the circumferential side. The ball 6 is interposed between the lower seat 30 and the umbrella body 5〇, and abuts against the lowest point A of the first concave surface 32 and the highest point of the third concave surface 54 from the point contact manner. c. Referring to the fourth figure, when the earthquake occurs, if the ground 24 moves to the right, the ball 6G will be driven to roll counterclockwise, and then the bottom end is connected with the first concave surface 32 of the lower seat 30; the sphere 60 The top end and the umbrella body 5 〇 the third concave surface 5 妾 the umbrella body 50 _ sway in the direction of the reverse sun, so that ', meet, the top of the special foot with a contact B, and the upper seat Then, due to the special shape of the umbrella ^), the following inequalities between the B and C points and B :: whmc' will be full 5C > Ψσ At this time, the upper seat 40 and the sphere are relatively stationary (―) Small, Lai will increase the height of the sphere 60 when the point is reached, but the point is rolled from A to A, and the difference between the sphere and the 6G is: ^, the height difference of the ^ can be reduced by the upper seat 40 and the vertical of the building 22 is reduced. Bit 6 20 1308187 = to reduce its seismic purity, and even to keep the building 22 stationary; thereby, the universal isolation device can not only effectively block the transmission of horizontal Wei, but also = construction 22. Thus produced a vertical record. When the earthquake stops, in order to restore the state of the purest and most stable, the city of the building 22 is minimized, and the universal isolation device 2G automatically returns to the position shown in the second and third figures. According to the spirit of the present invention, the universal isolation device 2 has various changes in structure, wherein the first concave surface 32, the second concave surface 42u surface 52, and the second concave surface 54 may also be ellipsoidal or other depending on the position. The replacement of the rounded curved surface of the curvature is not limited to the spherical surface, and any such imaginable changes are covered by the scope of the patent application of the present invention. 1308187 BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is a side view of a conventional universal isolation device; the second drawing is a side view of a first preferred embodiment of the present invention; and the third drawing is a first preferred embodiment of the present invention. The cross-sectional view; the fourth figure is slightly the same as the third figure, but shows the active state.
