Technical Field
[0001] The utility model relates to the field of transmission elements, and particularly to a novel structure of a special bearing for inline skates. Background Art
[0002] Bearings are used in inline skates, roller skates, etc. The existing bearing structure is to install an adapter wheel outside the bearing. After combining the axle center and other devices, fixing elements such as nuts are used to fix and prevent them from falling off.
[0003] However, the above structure is heavy, resulting in increased freight, or being cumbersome during movement, or lacking a sense of speed. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide a novel structure of a special bearing for inline skates to improve problems such as the heavy weight of the previous structure.
[0005] To this end, the utility model provides a novel structure of a special bearing for inline skates, which is characterized in that it includes:
[0006] A bushing, the center of which has a retaining wall;
[0007] Two sets of bearings, which are respectively pivotally connected to the bushing, and one side of each bearing is attached to the retaining wall;
[0008] Two sets of end caps, which include a covering surface and a pivot joint portion. The two sets of end caps are respectively connected to one end of the two sets of bearings opposite to the retaining wall through the pivot joint portion, so that the covering surface covers the end face of the bearing.
[0009] Wherein, a shaft tube is arranged inside the pivot joint portion, and the shaft tube is pivotally connected to the bushing.
[0010] A novel structure of a special bearing for inline skates, which is characterized in that it includes:
[0011] Two bearings;
[0012] Two sets of end caps, which sequentially include a covering surface, a pivot joint portion and a connecting section from the outside to the inside. The two sets of end caps are axially penetrated through the center of the bearing from one side of the connecting section, and the two bearings are sleeved on the pivot joint portion, and the covering surface covers the end face of the bearing. The connecting sections of each end cap are lap-jointed and combined concentrically.
[0013] Wherein, the connecting section is installed inside the pivot joint portion and is a metal tube body extending from the side opposite to the covering surface.
[0014] Through the above structural features, it can be understood that the utility model can reduce the weight of the bearing structure, and the operation is light when in use, increasing the sense of speed during use. Brief Description of the Drawings

Specific implementation manner
[0022] As Figures 1 to 2 shown, the new structure 100 of the inline skate special bearing in the first embodiment of the present utility model includes: a bushing 10, two groups of bearings 20, and two groups of end covers 30.
[0023] As Figure 1 , Figure 2 shown, the bushing 10 is used to axially connect the two groups of bearings 20, and a retaining wall 11 is provided at the center of the bushing 10.
[0024] As Figure 1 , Figure 2 shown, the two groups of bearings 20 are respectively axially connected to the bushing 10, and one side of each bearing 20 is attached to the retaining wall 11.
[0025] As Figures 1 to 2 shown, the two groups of end covers 30 include a covering surface 31 and a shaft connecting portion 32. The two groups of end covers 30 are respectively connected to the other ends of the two groups of bearings 20 opposite to the retaining wall 11 through the shaft connecting portion 32, so that the covering surface 31 covers the end face of the bearing 20.
[0026] The above is the structural introduction of the first embodiment of the present utility model. As Figure 3As shown, further, an axle tube 33 is provided inside the axle connecting portion 32. The two sets of axle tubes 33 are pivotally connected to the axle sleeve 10, so that the service life of the new structure 100 of the special bearing for inline skates can be increased.
[0027] As Figure 4 , Figure 5 shown, it is the new structure 200 of the special bearing for inline skates according to the second embodiment of the present invention, which includes: two sets of bearings 40 and two sets of end covers 50.
[0028] As Figure 4 , Figure 5 shown, the two sets of bearings 40 provide the combination of the two sets of end covers 50.
[0029] As Figure 4 , Figure 5 shown, the two sets of end covers 50 sequentially include a covering surface 51, an axle connecting portion 52 and a connecting section 53 from the outside to the inside; the two sets of end covers 50 are axially penetrated through the center of the bearing 40 from one side of the connecting section 53, and the two sets of bearings 40 are sleeved on the axle connecting portion 52, and the covering surface 51 covers the end face of the bearing 40, and the connecting sections 53 of each end cover 50 are lap-jointed and combined concentrically.
[0030] As Figure 6 shown, it is Figure 4 , Figure 5 the derived implementation method. The connecting section 53 is a metal pipe body installed inside the axle connecting portion 52 and extending from the side opposite to the covering surface 51.
[0031] From the above introduction, the advantages of the present invention will be introduced next.
[0032] 1. The weight of a set of the conventional bearing assembly is 21.99 grams. As for the new structure 100 of the special bearing for inline skates provided in the first embodiment, its weight is only 16.81 grams. The weight difference between the two is 5.11 grams. When used in roller skates or inline skates, 16 bearing assembly structures are required, and the overall weight is reduced by nearly 81.76 grams.
[0033] 2. As mentioned above, Figure 3 the bearing assembly structure is even only 15.08 grams, which is 110.56 grams less than that of the conventional bearing structure when used in inline skates or roller skates.
[0034] 3. Figure 4 The weight of the new structure 200 of the special bearing for inline skates provided by the second embodiment disclosed is only 16.3 grams, which is 91.04 grams less than that of the conventional bearing structure when used in inline skates or roller skates.
[0035] 4. Figure 6The structural weight is only 14.96 grams, which is 112.48 grams less than that of the conventional bearing structure used in roller skates or ice skates.
[0036] Therefore, when the present utility model is used, the movement is light and there will be no sense of heaviness in the legs, and the reduced effect can increase the sense of speed during use.
[0037] It should be noted that the above are specific embodiments of the present utility model and the technical principles applied. If changes are made based on the concept of the present utility model and the functions generated therefrom do not exceed the spirit covered by the description and the drawings, they should all be within the scope of the present utility model and are hereby noted.
