Description
Technical Field
The invention relates to the technical field of speed skating, in particular to a skating shoe capable of actively preventing spraining feet for speed skating beginners.
Background
The speed skating is sports on 400 m track with higher skating speed, and is helpful for improving physical and mental health, promoting human metabolism, improving cardiopulmonary function, enhancing cold-proof ability, and cultivating persistent willful quality.
If the Chinese invention discloses the number: CN107050832A is a speed skating boots, belongs to sports apparatus field. The problem that the lubrication effect obtained by the existing skates of the speed skating skates only depending on the pressure intensity of a human body is unreliable is solved. The shoe comprises a shoe body, a connecting frame and a knife body, wherein the knife body is fixed on the bottom surface of the shoe body through the connecting frame, the shoe further comprises a spray head, a connecting pipe, a water storage tank and a manual switch, the spray head is fixed on the upper surface of the front end of the knife body, a spray nozzle of the spray head points to the front of the front end of the knife body, a water inlet of the spray head is connected to a water outlet of the water storage tank through the connecting pipe, and the manual switch is arranged on the connecting pipe. When a skater is skating, the water is sprayed in front of the cutter body through the spray head, so that a water film is formed on the ice surface, the friction force between the cutter body and the ice surface is reduced, and the skating speed can be improved. The water sprayed out can not be instantly frozen, so that the problem that the human body pressure can not form a stable water lubricating effect after the temperature is reduced is solved.
Also, for example, the Chinese invention publication number is: the CN103357165A skates for skating comprise skate bodies, wherein the skate backs of the skate bodies are provided with mounting holes, the mounting holes comprise limiting holes arranged at the middle front parts of the skate backs, and the front and rear ends of the limiting holes are respectively provided with at least one waist-shaped connecting hole. The invention also discloses a pair of skates, which comprises a skate body, the skate blade and two connecting plates arranged on two sides of the skate blade through connecting components, wherein the top of each connecting plate is transversely provided with a positioning hole and an elongated hole which are used for being connected with the connecting hole at the bottom of the skate body, and the bottom of each connecting plate is provided with a screw hole corresponding to the limiting hole and the waist-shaped connecting hole of the skate body. The skate blade has a simple structure, can be quickly arranged at the bottom of the shoe body through the two connecting plates and the connecting assembly to form the skate, and can form a roller skate suitable for roller skating only by detaching the skate blade from the skate and arranging the pulley at the bottom of the shoe body through the connecting assembly and the connecting plates when the roller skating is needed, thereby being very flexible.
The speed is slided by beginner very easily to because the height of skating shoe is great, thereby appears spraining the foot phenomenon at the slip in-process, and traditional skating shoe ankle protectiveness is poor, can not initiatively protect the ankle, and fall the exposed skates of in-process and cut self or other personnel easily.
