Description

Sports training rings

technical field

The utility model belongs to the technical field of sporting goods, and relates to a lifting ring for sports training.

Background technique

The rings can exercise the muscles of the arms, shoulders and abdomen at the same time, and are gradually popularized in physical education. Different athletes have different heights, and hanging the rings in the same position is obviously not conducive to the stretching of all athletes' bodies. To this end, the Chinese patent discloses a sports lifting ring [authorized announcement number CN209500628U], when the length of the braid needs to be adjusted, the sealing plate can be rotated by the handle, so that the second screw is unscrewed from the second thread groove, At this time, there is a gap between the sealing plate and the inner wall of the flared groove. At this time, the braided belt can be pulled to adjust its length. After adjustment, the braided belt can be pressed between the sealing plate and the flared groove, so as to adjust the position of the braided belt. fixed.

Although the height of the above-mentioned lifting ring can be adjusted, there are still the following problems: the braided belt is limited by the pressing force of the sealing plate, which is easy to loosen and has a potential safety hazard; the two sides of the braided belt are independently adjusted, and the two sides cannot be guaranteed. The adjustment lengths of the sides are equal, which will cause uneven stress on both sides of the braided belt during use, which will affect the service life.

Preferably, the distance from the second regular polygonal prism to the rear end surface of the rotating shaft is greater than the length of the second through hole.

In the above-mentioned lifting ring for sports training, an annular baffle is arranged on the rotating shaft, and the annular baffle is against the front side of the connecting seat when the regular polygonal column 1 is fitted in the hole 1; There is a limit hole arranged perpendicular to the slot on the rotating shaft of the device, and a limit rod is arranged in the limit hole. When the annular blocking edge abuts on the front side of the connecting seat, the limit rod abuts on the rear side of the connecting seat . The shaft is axially limited by the annular baffle and the limit rod, so as to ensure the stability of the lifting ring during use and improve the safety. When the length of the sling needs to be adjusted, take the limit rod out of the limit hole, pull the rotating shaft forward, make the regular polygonal prism 1 separate from the perforation 1, and make the regular polygonal prism 2 separate from the perforation 2, and then rotate the shaft to adjust the length of the sling. After adjusting to an appropriate length, push the rotating shaft backwards, so that the regular polygonal column 1 fits into the hole 1, and the regular polygonal column 2 fits into the hole 2, and inserts the limit rod.

In the above-mentioned lifting ring for sports training, the distance from the rotating shaft to the left side of the connecting seat is equal to the distance from the rotating shaft to the right side of the connecting seat, and the central axis of the rotating shaft and the center line of the opening 1 are located on the same horizontal plane.

In the above-mentioned lifting ring for sports training, the regular polygonal prism 1 has 4-10 edges.

The lower end of the sling 1 is provided with a connecting seat 2 with a cavity inside, the connecting seat 2 is a cube, the left side of the connecting seat 2 is provided with an opening 1 3, the right side is provided with an opening 2, and the opening 1 3 and the opening 2 are flat. The two are arranged opposite each other and are on the same horizontal line. The width of opening 1 3 and opening 2 is slightly larger than the thickness of sling 1 , and the length of opening 1 3 and opening 2 is equal to the width of sling 1 . The front side of the connecting seat 2 is provided with a perforation 1 4, the rear side has a perforation 2 coaxially arranged with the perforation 1 4, a cylindrical rotating shaft 5 is pierced in the through hole 1 4, and the rear end of the rotating shaft 5 is pierced by the perforation 2, The rotating shaft 5 is provided with a slot 6 penetratingly provided along the radial direction of the rotating shaft 5 . Specifically, as shown in FIG. 5 , the slot 6 extends from the middle of the rotating shaft 5 to the rear end of the rotating shaft 5 .

As shown in Figures 1-3, one end of the sling 1 is inserted through opening 1 3, and after passing through the slot 6, it is pierced through opening 2. After the locking structure is used to lock the rotating shaft 5 in place, the bottom of the connecting seat 2 is connected with the lifting ring body 8 through the connecting belt 7 . When it is necessary to adjust the length of the sling 1, loosen the locking structure, rotate the rotating shaft 5 along its own central axis, and the rotating shaft 5 winds the sling 1 to make the distance between the beam and the connecting seat 2 smaller. The rotating shaft 5 is locked by the locking structure. Reverse rotation of the shaft 5 can make the suspender 1 longer.

When the regular polygon 1 9 is separated from the hole 1 4, the regular polygon 2 10 is separated from the hole 2. A certain distance is reserved at the rear end of the rotating shaft 5. After the rotating shaft 5 moves forward in the axial direction, the reserved section can also pass through the second hole. Preferably, the distance from the second regular polygonal prism 10 to the rear end surface of the rotating shaft 5 is greater than the length of the second through hole.

As shown in FIG. 4 and FIG. 5 , the rotating shaft 5 is provided with an annular baffle 11 , and the annular baffle 11 abuts on the front side of the connecting seat 2 when the regular polygonal column 1 9 is fitted in the through hole 1 4 . The rotating shaft 5 has a limit hole 12 arranged perpendicular to the slot 6, and a limit rod 13 is arranged in the limit hole 12. When the annular baffle 11 abuts against the front side of the connection seat 2, the limit rod 13 abuts against the connection seat 2 on the rear side. The shaft 5 is axially limited by the annular blocking edge 11 and the limit rod 13, so as to ensure the stability of the hoisting ring in use and improve the safety. When it is necessary to adjust the length of the sling 1, take the limit rod 13 out of the limit hole 12, pull the rotating shaft 5 forward, make the regular polygonal prism one 9 separate from the perforation one 4, and make the regular polygonal prism two 10 separate from the perforation two, and then rotate Rotate shaft 5 to adjust the length of the sling 1. After adjusting to a suitable length, push the rotating shaft 5 backward to make the regular polygonal prism 1 9 fit into the through hole 1 4, so that the regular polygonal prism 2 10 fits into the through hole 2, and insert the limit rod 13.

As shown in FIG. 1 , the distance from the rotating shaft 5 to the left side of the connecting base 2 is equal to the distance from the rotating shaft 5 to the right side of the connecting base 2 , and the central axis of the rotating shaft 5 is on the same horizontal plane as the center line of the opening 1 3 .
