Speed skate

Technical field

The present invention relates to a kind of speed skates, belong to sports apparatus field.

Background technique

There are mainly three types of the skating boots of existing skating: speed skate, figure-skating boots, ice hockey skating boots.Ice-sports are not from Skating boots are opened, and the key of skating boots is the skates of that two-edged benefit.For speed skate, its most important parameter is to slide Speed, and the frictional force for reducing skates and ice face is to improve a key factor of sliding speed.

Generally acknowledged theory thinks that for skater in skating, skates and ice face contact position pressure are very big, so that ice at this Fusing point reduce, the ice under the edge of a knife is fused into water, and the very thin one layer water of thawing is equivalent to lubricant, thus reduce skates with Frictional force between ice face, improves sliding speed.

The cutting edge of skates on skating boots is very narrow, and the blade of common skates only has 2mm wide, and the blade of figure skate is only 4mm wide, therefore, the contact area of skates and ice face are smaller.People be to the pressure on ground it is certain, after putting on skating boots, ice face Forced area reduce, the pressure that it is subject to will increase, and quality is that the people of 60kg puts on skating boots, his pressure to ice face About 46 or so standard atmospheric pressures, at this time the fusing point of ice can reduce 0.34K.Nevertheless, at present or it has been proposed that query, The reduction of ice fusing point caused by human body pressure, if under all temperature environments skater can obtain rapidly and stable Whether lubricant effect, this lubricant effect are also reliable under conditions of dropping at ambient temperature.It is analyzed from the angle of science, it is this Query is reasonable.There is the people of practical skating experience to can also be observed that under conditions of temperature is relatively low, skates more hold Ice face is easily scratched, and generates the ice bits to fall off, this proves that the frictional force of skates and ice face is increasing；And the condition slightly higher in temperature Under, it is easier to the trace observed after occurring water lubrication in the ice face just slipped over and build-up ice, this proves skates and ice face Frictional force is weakening.Therefore, in order to obtain higher skating speed, it should provide more stable lubrication and help.

Summary of the invention

The purpose of the present invention is to solve the skates of existing speed skate, the simple lubricant effect obtained by human body pressure Insecure problem.

The technical solution adopted by the present invention to solve the above problem is as follows: the present invention includes shoe body 1, connection frame 2 and cutter hub 3, Cutter hub 3 is fixed on the bottom surface of shoe body 1 by connection frame 2, it further includes spray head 4, connecting tube 5, water tank 6 and manual switch 7, Spray head 4 is fixed at the front end upper surface of cutter hub 3, and the spout of spray head 4 is directed toward at 1.5 to 5.5 millimeters of the front of 3 front end of cutter hub, The water inlet of spray head 4 is connected on the water outlet of water tank 6 by connecting tube 5, and manual switch 7 is provided in connecting tube 5.

The beneficial effects of the present invention are: 1, speed skater sprays water in skating, through spray head 4 in the front of cutter hub 3, thus Moisture film is formed in ice face, advantageously reduces the frictional force of cutter hub 3 Yu ice face, so as to improve sliding speed.In water tank 6 Water sprays tiny water flow by spray head 4 with determining direction, can play lubricating action and save the usage amount of water.2, due to The water of ejection cannot instantaneously build-up ice, after solving temperature decline, the problem of human body pressure cannot form stable water lubrication effect. 3, due to improving lubricant effect, skates are not easy to injure ice face, objectively improve the service life of ice face.It sprays water simultaneously Help to solve the problems, such as ice face injustice.4, the present invention both can be used for training of skating, and can be used for competing.
