Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings. It should be noted that the present embodiment is illustrative, not restrictive, and the scope of the invention should not be limited thereby.
A rebound prevention limiting device for a falling detection testing machine of a frame front fork assembly is characterized in that the rebound prevention limiting device 4 penetrates through and is connected to a protective coaming 3 on the top surface of a base 5 of the falling detection testing machine 1 in a sliding mode along the horizontal direction, the rebound prevention limiting device is used for unidirectionally limiting a lifting frame 2 of the falling detection testing machine, and the rebound prevention limiting device comprises a rubber roller 10, a horizontal frame 11 and elastic inclined strut units symmetrically arranged in the vertical direction; one end of the horizontal frame is rotatably sleeved on the roll shaft 12 of the rubber roll, and the other end of the horizontal frame slides along the horizontal direction to penetrate through the protective coaming; the elastic inclined strut unit comprises a slide rail 6, a slide block 8, a top pressure spring 7 and an inclined strut frame 9, wherein one end of the inclined strut frame is rotatably sleeved on a roll shaft of the rubber roll, and the other end of the inclined strut frame penetrates through and is rotatably connected to the slide block; the slide rail is fixedly arranged on the side wall of the protective enclosing plate, the slide rail is connected with the slide block in a sliding guiding manner, and the inner wall of the slide rail is fixedly connected with a jacking spring; the other end of the jacking spring is fixedly propped on the side wall of the sliding block.
Moreover, the bottom edge of the lifting frame of the drop detection testing machine is made into an arc-shaped curved surface 15 which is in abutting fit with the rubber roller, and the top edge of the lifting frame is made into a right-angle edge 14.
And the inclined strut frame and the horizontal frame are both U-shaped supports, and the opening ends of the inclined strut frame and the horizontal frame are symmetrical and are rotationally bridged on the roller shafts extending out of the two ends of the rubber roller.
