Abstract

The utility model relates to the rollers of roller skates, comprising a roller hub and a polyurethane plastic roller body which are formed into integration. The roller body is composed of an inner and an outer two layers of ring bodies with different softness and hardness, an inner ring body is made of polyurethane foamed plastics with safe quality and is coated on the peripheral face of the roller hub, an outer ring body is made of polyurethane plastic with hard quality, the center of the inner peripheral face of the outer ring body forms a concave shape, both sides of the outer ring body are respectively extended with a side edge which is covered and fixed on the peripheral face of the inner ring body, and the inner and the outer ring bodies coats the roller hub through an integral forming to form a roller body. The utility model has high strength and good shockproof effect.

Description

Skating shoe pulley

The utility model relates to a kind of ice skate, particularly relates to a kind of have shock-proof effect and high-intensity skating shoe pulley.

General ice skate are divided into the ice skate of being with skates and the ice skate of being with pulley, the ice skate of band pulley more are not subjected to the restriction in place, so long as the level land is just movable, so being subjected to general masses likes, in order on the level land, to slide, normally to have pulley, and cooperate the activity of foot, the user can be slided on the level land, reach as the effect and the enjoyment of skating.

Skating shoe pulley directly influences the contact of ice skate to ground, so structurally suitable intensity need be arranged, so general skating shoe pulley normally is made into integration with PU (polychlorostyrene base Ethyl formate) plastics, as shown in Figure 1, general skating shoe pulley 10 is to be made of a wheel hub 11 and a PU plastics wheel body 12, wheel hub 11 centers are run through and are provided with one wheel and connect hole 111, shaft-jointed hole 111 can penetrate for skating shoe shoe rack, pulley 10 is coupling on shoe rack, wheel hub 11 outside line side faces are convexly equipped with a bead 112, PU plastics wheel body 12 is coated on the bead 112, and forms a complete wheel body with wheel hub 11.

Though, above-mentioned pulley 10 can reach the purpose that ice skate slide, but still have shortcoming to exist in the use, general ice skate pulley 10 is in order to have intensity and pliability, PU plastics wheel body 12 is normally made with the PU plastics than hard, but this hard PU plastics are hard because of quality, can't make wheel body 12 have preferable shock-absorbing ability, so when sliding, can be because of uneven or little road surface of jolting that has of passing through, 12 reception and registration are vibrated to ice skate itself through PU plastics wheel body, and have influence on foot's nerve of user, and especially general ice skate have several PU plastics wheel bodys 12 usually, and what influenced is wider, the user is through after the strenuous exercise, the phenomenon that foot may occur aching.

Main purpose of the present utility model is to provide a kind of skating shoe pulley, makes whole pulley have intensity height and the good advantage of shock-proof effect.

The skating shoe pulley of the utility model, comprise a wheel hub and a PU plastics wheel body and one-body molded, it is characterized in that: this PU plastics wheel body is made of the ring body of inside and outside two-layer different soft and hard degree, this inner ring body is to make with the PU foamed plastic of softer, and being coated on the outer peripheral face of this wheel hub, this outer ring body is made with the PU plastics than hard, and is coated on the outer peripheral face of this inner ring body, should coat wheel hub by inside and outside ring body, and form intensity height and the good complete wheel body of shock-absorbing.

Described skating shoe pulley is characterized in that: the inner peripheral surface central authorities of described outer ring body are recess, respectively stretch out a lateral margin in both sides, and described lateral margin is coated and fixed on the side face of described inner ring body.

Below by most preferred embodiment and accompanying drawing the skating shoe pulley of the utility model is elaborated, in the accompanying drawing:

Fig. 1 is the sectional axonometric drawing of general ice skate pulley.

Fig. 2 is the sectional axonometric drawing of the utility model preferred embodiment.

Fig. 3 is the flat assembly drawing of the above-mentioned preferred embodiment of the utility model.

Fig. 4 is the combination schematic diagram of above-mentioned preferred embodiment of the utility model and ice skate shoe rack.

Shown in Fig. 2,3, the profile of the skating shoe pulley of the utility model and general skating shoe pulley are similar, comprise a wheel hub 20 and a PU plastics wheel body 30, the center of wheel hub 20 is run through and is provided with a shaft-jointed hole 21, shaft-jointed hole 21 can supply skate frame (the figure end shows) to be inserted in the pulley that is coupling, and shaft-jointed hole 21 outer rim side face epireliefs are established a bead 22, and bead 22 can coat for PU plastics wheel body 30 and be fastened on the wheel hub 20.

PU plastics wheel body 30 of the present utility model is that the ring body by inner ring body 31 and outer ring body 32 two-layer different soft and hard degree constitutes, inner ring body 31 is to make with the PU foamed plastic of softer, and be coated on the bead 22 of wheel hub 20 outer peripheral faces, outer ring body 32 is to make with the PU plastics than hard, the centre of inner circumferential surface is recess, and respectively stretch out a lateral margin 321 in both sides, can limit outer ring body 32 is coated and fixed on the outer peripheral face of inner ring body 31, make inner ring body 31 between wheel hub 20 and outer ring body 32, inner ring body 31 is all made by the PU plastics with outer ring body 32, both have good compatibility, so in,

outer ring body

31,32 is can one fastening and be coated on the wheel hub 20, and form complete pulley.

The utility model compared with prior art has following effect:

Cooperate shown in Figure 4, the utility model ice skate pulley is to be coupling on skating shoe shoe rack 1, in the present embodiment, this ice skate shoe rack 1 is the in-line arrangement ice skate, when putting on ice skate, the user passes through when jolting the road surface, the outer ring body 32 of PU plastics wheel body 30 directly contacts with ground, because of outer ring body 32 is to be made by the PU plastics than hard.So have higher intensity, pliability is then lower, after being subjected to ground shock, vibration is conveyed on the inner ring body 31, inner ring body 31 is to be made by the PU foamed plastic of softer, has higher resiliency, because be expanded material, so have good damping capaicty, when vibration was communicated to inner ring body 31, inner ring body 31 is absorbing vibration power effectively, can reduce the vibrational energy that is communicated on the shoe rack 1.

In sum, PU plastics wheel body 30 of the present utility model constitutes with the inner and outer ring body structure of two-layer different soft and hard degree, outside outer ring body 32 has higher intensity, can bear impact from the road surface, and inner inner ring body 31 has higher pliability, can eliminate the vibration that the ground injustice is brought,, make to the utlity model has the high and good shock-proof effect of intensity with inside and

outside ring body

31,32 Overmolded complete pulleys.
