Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
Detailed description of the invention one
The formation of the utility model Handle of skipping rope is described below in conjunction with accompanying drawing, especially describes the bearing arrangement as the utility model key point in detail.This bearing-type Handle of skipping rope comprises handle body, turning cylinder 3 and the multiple spheroid 4 that handle leading portion 2 is formed with handle back segment 1, wherein, forms bearing arrangement by handle leading portion, turning cylinder and the multiple spheroids as rolling element.
For cylindrical structural that the handle back segment grasped is inner hollow during use.Its hollow length not necessarily needs to run through whole handle back segment, but, at least need to ensure that the junction with handle leading portion is hollow.
Handle leading portion is detachably fixed on handle back segment.In the present embodiment, the external screw thread 1a being located at handle back segment can be adopted to be connected and fixed with the internal thread 2a being located at handle leading portion.
The first half of handle leading portion is dome-shaped structure, be shaped with in the crown center position of dome-shaped structure for the cord insert port 2b through rope skipping cord, and the rolling element being shaped with a circle depression on the cavity inner wall of handle leading portion near the position of cord insert port supports kerve 2c.The section that this rolling element supports kerve is crescent or semilune.
Turning cylinder is the cylindrical cavity that centre is provided with through rope skipping cord, and front is thin, and rear is thick.Further, the rolling element outer wall of turning cylinder being shaped with a circle depression supports inverted draw cut 3a.
As shown in Figure 1, turning cylinder enters fixing from the handle back segment installation nose end of handle leading portion to cord insert port side pressure.Now, rolling element supports kerve and rolling element and supports and form rolling element between inverted draw cut and lay chamber, and lay around multiple spheroid in chamber at this rolling element, spheroid can roll in this space.
The number of spheroid is at least 2, and in the present embodiment, spheroid is 6, and these spheroids play the effect of rolling element in bearing arrangement.
In addition, the diameter of spheroid is greater than the degree of depth that the rolling element be located on handle leading portion inwall supports kerve, ensures that spheroid supports kerve from rolling element and upwards leans out.
Handle back segment, handle leading portion, turning cylinder and spheroid all adopt resin material to make.Easily volume production is realized by extrusion forming process, and lightweight.Further, the bearing arrangement be made up of resin material, operationally, the Contact of each parts (i.e. handle leading portion, turning cylinder and spheroid), can produce certain resistance, thus avoids producing sideslip and idle running.
Further, the resin that on handle leading portion, rolling element supports near kerve adopts transparent or semitransparent structure, Bearning mechanism can be very clear from the outside, can provide good visual experience.Painted by spheroid, can create and adopt various design more.
The assemble method of Bearning mechanism is described below in conjunction with Fig. 2.
First, as shown in Fig. 2-1, at the multiple spheroid of cord insert port place circle distribution of handle leading portion; Then the internal cavities side direction cord insert port direction of turning cylinder from handle back segment is inserted, in the process inserted, the protruding 3b of jaw on rolling element support inverted draw cut and the outer rim of each spheroid abut against, when continue by direction from turning cylinder to arrow A press-in time, spheroid can give the power in a turning cylinder head B direction, when jaw projection exceedes spheroid, as shown in Fig. 2-2, the rolling element that spheroid is squeezed into handle leading portion supports in kerve, and the stressed of turning cylinder head is eliminated.
Under the state of Fig. 2-2, jaw is protruding is lived by each sphere constraint, and turning cylinder can not come off.Meanwhile, multiple spheroid is scrolled body and supports rolling element that kerve and rolling element support, top formed and lay chamber and retrain, and also can not come off.Adopt the structure that this turning cylinder and each spheroid retrain mutually, a small amount of parts of use just can realize the structure of bearing.
Through rope skipping cord 5 on this bearing-type Handle of skipping rope, and cord is fixed on cord folder 6, namely completes the assembling of rope skipping.
Fig. 3 is the structural representation be installed on by cord on handle body.Cord mounting board is contained on cord, by cord folder force, can realize cord and be clipped in movement on cord, so, just can realize the adjustment of cord length, facilitate the user of different occupation mode or different height to use.
In addition, the width of cord folder is less than the width of handle back segment cylindrical hollow configuration, avoids cord to press from both sides the contact internal walls with handle back segment.
When utilizing the handle rope skipping with structure shown in Fig. 3 to carry out rope skipping, owing to rotating the centrifugal force produced with cord, cord in figure 3, by toward towards the direction pull-up of cord insert port.And the cord folder of fixing cord also pulls to the direction of cord insert port, turning cylinder is pushed to the front portion of handle leading portion.Therefore, ensure that turning cylinder can not come off in rope skipping.
As mentioned above, under the present embodiment, describe the optimum structure of Handle of skipping rope, but the utility model is not limited only to this example.Such as, form the handle back segment 1 of handle body and the method for attachment of handle leading portion 2, be not limited to screw, can be realized by assembling, the retaining mechanism from outside also can be set, also can utilize the adhesion of magnet, in a word, as long as removably fixing means is just passable.
In addition, handle leading portion and handle back segment also can be designed to the structure of integral type by handle body, and turning cylinder is pressed into by the rear portion of handle body.But due to the structure of integral type, the stroke causing turning cylinder to be pressed into is longer, is not easy to the assembling of turning cylinder, so, the utility model handle body is designed to split type structure for optimum.
Detailed description of the invention two
Handle of skipping rope about the utility model detailed description of the invention two is formed, and illustrates below in conjunction with accompanying drawing.
Be with the difference of the Handle of skipping rope of embodiment one, the spheroid as rolling element is replaced by cylindrical rolling element 4a, and other formations, assemble method and action are identical.
In addition, rolling element also can be designed to the various shape that can rotate, and such as, Fig. 5-1 is cylindrical rolling element, and Fig. 5-2 is conical rolling element, and Fig. 5-3 is barrel-shaped rolling element.
Turning cylinder and multiple rolling element adopt the structure mutually retrained, and compared with the degree of depth supporting kerve, need the maximum gauge increasing rolling element spin with rolling element, ensure that jaw projection contacts with rolling element with this.In addition, the Breadth Maximum of rolling element refers to as shown in the dotted arrow in Fig. 5, perpendicular to the maximum gauge in the plane of rotating shaft.If the spheroidal spheroid shown in embodiment one, it is the diameter of spheroid perpendicular to maximum gauge in the plane of rotating shaft.
Other structure is with detailed description of the invention one.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
