Lower connecting rod-shaped breaststroke sliding plate

Abstract

The invention discloses a lower connecting rod-shaped breaststroke sliding plate which comprises two bottom plates, two surface plates, a lower connecting rod and four universal wheels, wherein the two bottom plates are made of plastics through injection molding, wheel bases are respectively arranged at the front ends and the rear ends of the two bottom plates, bearings are respectively embedded on and under the inner sides of the bottom plates, upwards vertical edges are arranged on the edges of the two bottom plates, latticed reinforced ribs are arranged on the two bottom plates, anti-slip strips are connected to the reinforced ribs, the two surface plates are made of the plastics through injection molding, the outer diameters of the two surface plates correspond to the inner diameters of the upwards vertical edges on the edges of the two bottom plates, strip-shaped holes in the two surface plates correspond to the anti-slip strips on the reinforced ribs of the two bottom plates, the two surface plates are connected with the two bottom plates by using bolts, the lower connecting rod is a metal round rod, two ends of the metal round rod are bent by forming a right angle and the middle of the metal round rod is bent twice by forming obtuse angles, threaded holes are formed in two ends of the lower connecting rod, two ends of the lower connecting rod penetrate in inner holes in an upper bearing and a lower bearing at the front ends of the two bottom plates for being located, and the four universal wheels are arranged on the front wheel bases and the rear wheel bases of the two bottom plates.

Description

Technical field: [0001] The present invention relates to a skateboard, in particular to a frog-style skateboard in the form of a lower link rod that can move forward rapidly by standing on two boards of the skateboard with two feet and twisting the two feet or swinging the rear foot. technical background: [0002] Although the frog skateboard previously designed by the designer has achieved a certain expected effect, there will be an uncomfortable feeling when stepping on the front foot in the way of swinging the foot. Invention content: [0003] The object of the present invention is to provide a lower link-shaped frog skateboard with a low center of gravity and comfortable and natural sliding. The purpose of the present invention is achieved like this: the lower link-shaped frog skateboard comprises two bottom plates, two panels, a lower connecting rod and four universal wheels, and is characterized in that: the two bottom plates are formed by plastic injection molding, ...
