Detailed Description

The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the utility model, but are not intended to limit the utility model in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the utility model. All falling within the scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a buffering docking device, which includes a bracket body 10, a positioning column 20, a mounting seat 40 and an elastic washer 30. The bracket body 10 is a square frame of aluminum alloy or carbon steel; the positioning column 20 comprises a conical section 21, a mounting step 22 and a connecting section 23 which are sequentially connected, the tip end of the conical section 21 is arranged upwards, the connecting section 23 is arranged on the bracket body 10, and the mounting step 22 is provided with a connecting hole; the mounting seat 40 comprises a connecting plate 41, a waist-shaped hole 42 arranged in the middle of the connecting plate 41, a side plate 43 extending from the edge of the waist-shaped hole 42 to one side, and a first flange 44 extending inwards from the side plate 43, and the mounting seat 40 is arranged on the upper surface of the bracket body 10 and distributed along the edge of the bracket body 10; the elastic pad 30 comprises a waist-shaped pad 31 and a second flange 32 extending outwards from the side edge of the waist-shaped pad 31; the connecting plate 41 is disposed on the bracket body 10, and the bracket body 10, the side plate 43 and the first flange 44 form an accommodating space for accommodating the second flange 32.
