Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 shown, the trampoline ball rope includes an elastic rope 10 and a ball head 20. Both ends of the elastic rope 10 are bent and knotted to form a knot so that the elastic rope 10 is in a loop shape. The elastic rope 10 is threaded through the through hole of the ball head 20 and the jumping mat in a double-strand form and is sleeved with the assistance of the auxiliary device for installing the trampoline ball rope;

[0024] However, when installing and fixing the trampoline ball rope in the trampoline structure, it is quite laborious and time-consuming, and the ball head hole diameters used for trampolines of different diameters are not the same. If the ball head hole diameter is larger, it will be more difficult to install.

[0025] Therefore, this embodiment discloses an auxiliary device for installing a trampoline ball rope, which includes a handle 1 and a working end 2 connected to the handle;

[0026] The working end 2 is of a cylindrical structure and can be telescoped and variable in diameter. The working end can be inserted into the ball head 20 to assist the loop of the elastic rope 10 to be sleeved from the outside to the other side of the ball head 20.

[0027] As Figures 2 to 4 shown, the working end 2 includes an outer shell 21 integrally connected to the handle and a multi-stage hollow rod 22. The multi-stage hollow rod 22 is placed inside the outer shell 21 and can extend out of the outer shell 21. When the multi-stage hollow rod 22 extends out of the outer shell 21, the outer side of the end of the multi-stage hollow rod 22 close to the outer shell 21 is threadedly connected to the inner side of the outer shell 21 close to the multi-stage hollow rod 22.

[0028] In this embodiment, the multi-stage hollow rod 22 includes a primary hollow rod 221 and a secondary hollow rod 222;

[0029] The primary hollow rod 221 is threadedly connected to the outer shell 21, and the secondary hollow rod 222 is placed in the primary hollow rod 221 and can extend out of the outer shell 21. When the secondary hollow rod 222 extends out of the primary hollow rod 221, the outer side of one end of the secondary hollow rod 222 close to the primary hollow rod 221 is threadedly connected to the inner side of the primary hollow rod 221 close to the secondary hollow rod 222.

[0030] In this embodiment, a hook 3 is also included, and the hook 3 is in a "J" shape. One end of the hook 3 bent outward is arranged inside the secondary hollow rod 221, and the other end can extend out of the secondary hollow rod 221. The end of the hook 3 bent outward is used to carry the secondary hollow rod 221 and the primary hollow rod 222 and / or the primary hollow rod 222 is rotationally locked with the outer shell 21 when rotating externally.

[0031] In this embodiment, a long strip-shaped groove is provided inside the primary hollow rod 221 along its axial direction, and the bent section of one end of the hook 3 bent outward is embedded in the long strip-shaped groove and can move along the long strip-shaped groove.

[0032] In this embodiment, a limiting ring 4 is further included. The limiting ring 4 is arranged inside the secondary hollow rod 221 and is located at one end of the long strip groove away from the primary hollow rod 222.

[0033] The hollow structure of the limiting ring of this embodiment allows the upper end of the hook 3 to pass through, while limiting the bent section of the outwardly bent end of the hook 3 to prevent the bent section of the outwardly bent end of the hook 3 from escaping from the long strip groove.

[0034] In this embodiment, the hook 3 is tilted out of the secondary hollow rod 221, and then pulled outward and rotated, so as to drive the secondary hollow rod 221 to rotate and be threadedly fixed to the primary hollow rod 222, and also drive the primary hollow rod 222 to rotate and be threadedly fixed to the outer shell 21; the fixation can also be released by rotation to achieve the change of the diameter of the multi-stage hollow rod 22, thereby ensuring that the trampoline ball rope installation auxiliary device can adapt to ball heads 20 of different diameters.

[0035] In this embodiment, the housing 21, the primary hollow rod 222, and the secondary hollow rod 221 are all made of steel with a thickness greater than or equal to 0.1 mm.

[0036] In this embodiment, a handle cover 5 is further included. The handle cover 5 is sleeved on the outer side of the handle 1. The handle cover 5 is provided with protrusions and depressions that fit with the hand when holding.

[0037] The trampoline ball rope installation auxiliary device is generally made of iron or steel materials. To ensure the holding comfort and reduce problems such as abrasion and blisters caused by the direct contact of iron or steel with people, a handle sleeve 5 can generally be added. The handle sleeve 5 is made of flexible materials such as rubber or sponge.

[0038] The present utility model provides a trampoline ball rope installation auxiliary device. The working end 2 that can be telescopic and variable in diameter is used to enable it to be inserted into the ball head 20 with different diameters. And through the lever principle, the elastic rope can be more conveniently sleeved on the other side of the ball head 20 with a smaller force, thereby accelerating the installation speed of the trampoline and reducing the labor intensity of personnel.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present embodiments. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present embodiments. Therefore, the present embodiments will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
