Abstract
The invention relates to a standstill-locking connecting device and the application thereof; the standstill-locking connecting device is composed of a rope, core sandwiches, a sleeve and a connecting rotating shaft which are assembled in a connecting way; the two ends of the connecting rotating shaft is connected with a shaft head, and are arranged in the holes of two core sandwiches; the opening is penned for leading the rope to be clamped among the tooth bulges; the sleeve is respectively sheathed on the core sandwich along the rubber band direction, thus leading the ring-shaped lug bosses of the core sandwiches to be blocked in ring-shaped grooves; and the connecting rotating shaft can freely rotate along the axial direction in the holes. Working deformation generated in movement can be restored at the position of the connecting rotating shaft, therefore, the rope can not be wound and convenience is brought for sport persons.
Description
Technical field
The present invention relates to sporting goods, particularly a kind of coupling device for stopping rotation and application thereof.
Background technology
The tennis resilience device of people's use at present is the tennis that a bar rubber band connects, because tennis can rotate in the process of batting, under the rotation of tennis, will drive rubber band and twist, the rubber band strain can produce power, this power can not get discharging, rubber band will twine under the effect of this power, makes troubles to the user, and skipping rope simultaneously and shaking rope also is an independent rope, rope also can twine in the rope skipping process, brings inconvenience to the sportsman.
Summary of the invention
Technical problem to be solved by this invention provides a kind of coupling device for stopping rotation and application thereof, can overcome the defective that existing ball resilience device is easy to generate winding.Coupling device for stopping rotation of the present invention not only can be used as ball resilience device, and also useful application is to doing the rope skipping that is easy to generate winding, shaking in the exercise such as rope.
Solving the problems of the technologies described above the technical scheme that is adopted is coupling device for stopping rotation of the present invention, by rope (flexible rope or nonelastic rope), sandwich, sleeve, the connection rotating shaft connects to form and forms, wherein, the two ends that connect rotating shaft link to each other with spindle nose, connecting rotating shaft is the thin rotation body structure in big centre, two ends, and be installed in two sandwich holes, sandwich one end is inner for having detent projection, the other end is porose, and the side in the hole has opening, the opposite side imperforation, the outside is provided with annular boss, open opening, rope be sandwiched between the detent projection, sleeve be enclosed within respectively sandwich on.Sleeve is a tubulose, and there is annular groove its inboard.
Coupling device for stopping rotation of the present invention can be divided into one or more snippets with rope, and rope can seal or not seal, and that does not seal can at one end be connected with moving object, and the rope other end is connected with other fixtures.
Beneficial effect of the present invention is simple and practical, rope can not take place during motion twine, and helps the sportsman better to move.

The specific embodiment
Below in conjunction with specific embodiment, further set forth structure of the present invention.
A kind of coupling device for stopping rotation, be characterized in by rope (flexible rope or nonelastic rope) 1, sandwich 2, sleeve 3, connecting rotating shaft 4 connections combines, the two ends that wherein connect rotating shaft 4 link to each other with spindle nose 10 and are installed in the hole 8 of two sandwiches 2, opening opening 6 is sandwiched in rope 1 between the detent projection 5, sleeve 3 is set on the sandwich 2 along rope 1 direction respectively, make the annular boss 7 of sandwich 2 snap in the annular groove 9 of sleeve 3, an end of a rope 1 is connected with moving object therein, another root rope 1 is connected with fixed object, connecting rotating shaft 4 can freely rotate along axial in hole 8, the power that rope 1 passive movement object rotating band movable property is given birth to during motion will connect rotating shaft place release, and rope 1 just can not twine.
Embodiment one
Coupling device for stopping rotation of the present invention is applied on the tennis resilience device, one end of the rope 1 of coupling device for stopping rotation is connected with fixture, in motion process, because impacting tennis can produce rotation, rope will reverse, and rope is because strain and generation power, and the junction that this power reaches between the rope can obtain discharging, rope just can not tied a knot together, brings conveniently to the sportsman.
Embodiment two
Coupling device for stopping rotation of the present invention is applied in rope skipping, shakes on the rope, because a rope is easy to when shaking and can twines, use coupling device for stopping rotation, rope is divided into one or more snippets, the rope rotational deformation just can not produce or strengthen, rope can not twine, and its principle is identical with embodiment one.
