Rigidity rope section is slidably matched with hollow tube, and multistage rigidity rope section combination forms the core of hollow tube.
The length of every section of rigidity rope section is 10-30mm.
The rope body is provided with two counterweight points, and the distance of two counterweight points to its corresponding handle is equal, and each counterweight
Point at corresponding to rigidly restrict section quality be more than remaining rigidly rope section quality.
The counterweight point to the distance of its corresponding handle is 0.5-1.5m.
The hollow tube is pipe.
The rigidity rope section is middle cylindrical structure thick, both ends are thin, and two end faces of rigidity rope section are sphere.
The handle front end is provided with bearing, and grafting enters in corresponding bearing respectively at rope body both ends.
It is mounted on outwards inserting respectively corresponding in the tapered sleeve of shrink mouth shape, the rope body both ends at the inner ring of the bearing
It is connected in tapered sleeve and with its clamping.
The bearing is taper roll bearing.
The beneficial effects of the utility model are：
Rope body is flexible hollow tube in the utility model, is uniformly arranged along its length in hollow tube firm provided with multistage
Property rope section, rigidity rope section is the linear type structure that is engaged with the size of the hollow tube, and every section of rigidity rope section with it is hollow
Pipe is slidably matched, and rigidly rope section combines the core for forming hollow tube, the more conventional rope body of rope body structure that combinations thereof is formed to multistage
Architecture quality is heavier, and so as to avoid restricting during rope skipping, body wafts phenomenon, and multistage rigidly rope section and hollow tube
Coordinate, can prevent from restricting after body is stored produces knotting.
The length of every section of rigidity rope section is 10-30mm, to ensure to form the degree of flexibility of rope body.
The handle front end is provided with bearing, and grafting enters in corresponding bearing respectively at rope body both ends, to overcome rope skipping to make
The caused torsion between rope body and handle during.Also, the utility model middle (center) bearing selects taper roll bearing, and it is compared
Plain bearing can bear radial load and single direction axial load, strengthen service life.
It is mounted on outwards inserting respectively corresponding in the tapered sleeve of shrink mouth shape, the rope body both ends at the inner ring of the bearing
It is connected in tapered sleeve and with its clamping, is easy to connection installation of the body at bearing of restricting.
Hollow tube described in the utility model is pipe, and the rigidity rope section is middle cylindrical structure thick, both ends are thin, and
Two end faces of rigidity rope section are sphere, and the docking sections of two rigidity rope sections are sphere docking, are easy between the two relative
Rotate to simulate rope body, and also help assembling of the rigidity rope section in hollow tube, be easy to produce, it is easy to spread.
The rope body is provided with two counterweight points, and the distance of two counterweight points to its corresponding handle is equal, and each counterweight
The quality of section of rigidly being restricted corresponding at point is more than remaining rigidly rope section, and counterweight point is designed to further avoid in rope skipping process
Middle rope body wafts phenomenon.
The utility model is simple in construction, easy to use, and rope body wafts when not only avoiding using, and is beaten after preventing storage
Knot.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model；
Fig. 2 is the enlarged drawing at A in Fig. 1；
Fig. 3 is the enlarged drawing at B in Fig. 1.
Embodiment
Specific embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2 and Figure 3, the anti-rope skipping that knots of one kind of the present utility model, including rope and are respectively arranged at rope at body
Two handles 1 at body both ends, the body of restricting are uniform along its length in hollow tube 2 to arrange provided with more for flexible hollow tube 2
Section rigidity rope section 3, rigidity rope 3 linear type structure to be engaged with the size of the hollow tube 2 of section, and every section of rigidity rope section 3
It is slidably matched with hollow tube 2, rigidly rope section 3 combines the core for forming hollow tube 2 to multistage.
The more conventional rope body architecture quality of rope body structure that combinations thereof is formed is heavier, so as to avoid body of being restricted during rope skipping
Waft phenomenon, and the cooperation of multistage rigidly rope section and hollow tube, knotting is produced after the body storage that can prevent from restricting.
In the present embodiment, the length of every section of rigidity rope section is 20mm, to ensure to form the degree of flexibility of rope body.Also, institute
It is pipe to state hollow tube 2, and the rigidity rope section 3 is middle cylindrical structure thick, both ends are thin, and rigidity rope saves 3 two end faces
It is sphere, the docking section of two rigidity rope sections 3 is docked for sphere, is easy to relative rotation between the two to simulate rope body, and
And assembling of the rigidity rope section in hollow tube is also helped, and it is easy to produce, it is easy to spread.
In the present embodiment, the distance that rope body is provided with two counterweight points C, two counterweight point C to its corresponding handle 1 is equal,
And rigidly the quality of rope section 3 is more than remaining rigidity rope section corresponding at each counterweight point C, counterweight point is designed to further keep away
Body of exempting to restrict during rope skipping wafts phenomenon.In the present embodiment, counterweight point C to the distance of its corresponding handle is 1m, should
Numerical value is set according to the height of rope skipping user.
The front end of handle 2 is provided with taper roll bearing 4, be mounted at the inner ring of taper roll bearing 4 be in outwards
The tapered sleeve 5 of shrink mouth shape, rope body both ends are inserted in corresponding tapered sleeve 5 and are connected with its clamping respectively, to overcome rope skipping using
Caused torsion between rope body and handle in journey.Also, the utility model selects taper roll bearing, it compares plain bearing energy
Radial load and single direction axial load are enough born, strengthens service life.
The utility model is simple in construction, easy to use, and rope body wafts when not only avoiding using, and is beaten after preventing storage
Knot.
