Gear adjusting type rear wheel locking device for ice skates

Abstract

The invention discloses a gear adjusting type rear wheel locking device for ice skates. The gear adjusting type rear wheel locking device comprises a fixed frame, a rotary adjusting rod, a gear, a limiting rack, a return spring and a locking block, wherein corresponding fixing parts are downwards arranged at two sides of the fixed frame; two ends of the rotary adjusting rod are respectively and correspondingly inserted in the two fixing parts, and an adjusting head exposing out the outer side surface of the corresponding fixing part is arranged on one end of the rotary adjusting rod; the gearis fixedly arranged on the rotary adjusting rod; the limiting rack is vertically arranged on the rotary adjusting rod; the return spring keeps providing a return force towards the adjusting head to the rotary adjusting rod; the locking block can be arranged between the two fixing parts in an up-and-down sliding way; a transmission rack in a vertical direction is arranged on the side wall of the locking block. When the rotary adjusting rod is inwards pressed through the adjusting head, the limiting rack and the transmission rack are staggered, and the gear is engaged with the transmission rack.The gear adjusting type rear wheel locking device disclosed by the invention is simple in operation, the stability of rear wheel locking is better, and the safety is increased.

Description

technical field [0001] The invention relates to a gear-adjustable rear wheel locking device for skates. Background technique [0002] Ice skating is loved by the public because of its speed and other characteristics, and the must-have item for skating is roller skates. The brakes of roller skates are completed by the brake pads at the rear end. For beginners, roller skates are also equipped with a pulley locking device. Part of the pulleys are locked during learning. By locking the pulleys, it is more convenient for beginners to complete exercises such as balanced walking. The pulleys of existing skates are usually locked by springs to provide locking force. Because the springs have fatigue life, instability and The problem of uneven force leads to insufficient locking force and low adjustment controllability due to errors in processing dimensions, which also makes it easy for beginners to fall during learning.
