Portable four-wheel pendulum pin slide plate
Technical field
The present invention relates to a kind of slide plate, particularly a kind of portable four-wheel pendulum pin slide plate.
Technical background
The kind of existing market upper slide is also few; Also do not have portable four-wheel pendulum pin slide plate; " four-wheel wag the tail formula slide plate " that the design people formerly designs, though designed the four-wheel slide plate that the pendulum pin slides, folding more complete, still have deficiency aspect more portable after folding.
Summary of the invention
The object of the invention is to provide a kind of structure more perfect, is more convenient for folding, the portable four-wheel pendulum pin slide plate of being more convenient for carrying.The objective of the invention is to realize like this; Portable four-wheel pendulum pin slide plate; Comprise front running board, bumper step and universal wheel; It is characterized in that: a universal wheel is installed in the bottom of the front end of front running board; A universal wheel is respectively installed in the bottom on both sides, front running board rear portion; The rear end of front running board is equipped with bearing; The front end of bumper step bottom is fixedly connected a minor axis, and minor axis penetrates in the brearing bore that is installed on the front running board rear end, and a universal wheel is installed at the rear portion of bumper step bottom.
The invention has the beneficial effects as follows: bearing is installed in the rear end of front running board; The front end of bumper step is fixedly connected minor axis; The minor axis of bumper step and the bearing on the front running board match, and make the portable four-wheel slide plate not only have the good function that moves ahead, and have good folding portable function.
