The construction principle of double-row roller skates and Toe covers roller skates
Double-row roller skates are mainly composed of four parts: upper shoe, axle frame, bearing, and wheel.
All parts are connected into a hole through the axle frame.
Toe covers roller skates have a certain protective effect on roller skates, to a certain extent, reduce wear, scratch resistance, anti-collision, and better protect the toe cap.
The main items of double-row roller skating are figure skating, speed skating, roller skating, and free skating. Some people use roller skates for parades or team blocking games outdoors.
Speed skating double-row roller skates are all short uppers so that athletes can squat to better complete the skating action. Low-top shoes can also meet the requirements because the wheel diameter is small and the angle of attack is small. The common materials for upper shoes are plastic plus upholstery, artificial leather, and leather. High-end shoes basically use cowhide soles and use cowhide or artificial leather materials to make upper shoes, which are light and comfortable.
The axle frame of double-row shoes is completely different from that of single-row shoes. The basic structure is that many mounting holes are made on a large base plate. Some of the mounting holes are used to connect the axle frame to the shoe. Generally, there will be left at the head of the base plate. A mounting hole is used to install the brake. The four most important mounting holes on the axle frame are used to install the shock absorber. The material of the shock absorber is soft rubber or soft resin. Because the double-row roller skates are in the corner when sliding, the inner and outer wheels are grounded most of the time, so the deformation of the shock absorber must be relied on to provide the centripetal force. Above the shock absorber, there is an axle rod for mounting wheels.
The base plate of the pedestal is very wide and has multiple mounting holes to connect with the upper shoe. This is why the upper shoe does not require too much strength. The brakes of speed skating shoes are usually very small.
Damping pads are usually relatively soft so that they can provide a large amount of inclination to generate sufficient centripetal force.
