Detailed Description
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to fig. 1 to 5
The utility model provides a three-dimensional elevator buffer based on metal rubber, includes base 10, the mid-mounting of base has impact-resistant metal rubber 11, and the top of base is provided with upper cover plate 20, install the leaf spring 30 that lower extreme and base are connected along the circumferencial direction interval on the downside of upper cover plate, put can elastically flexible link assembly 40 to one side between the adjacent two leaf springs, link assembly's upper and lower end is connected with upper cover plate, base respectively.
In this embodiment, in order to cooperate with the metal rubber that shocks resistance, reach the protecting against shock better, be provided with downward bellied boss 21 on the downside of upper cover plate, the boss is located the top of the metal rubber that shocks resistance.
In this embodiment, in order to place the anti-impact metal rubber, the middle portion of the base is provided with a circular clamping groove 12, and the anti-impact metal rubber is placed in the circular clamping groove to prevent the anti-impact metal rubber from shifting.
In this embodiment, in order to realize being connected of leaf spring and upper cover plate and base, the upper end of leaf spring is connected with the draw-in groove that sets up on the upper cover plate downside through the bolt, and the lower extreme of leaf spring is connected with the hole site that sets up on the base through the bolt. The plate spring is arc-shaped.
