Detailed implementation manners

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0028] Embodiment 1

[0029] As Figure 1As shown in the figure, an auxiliary training device for sphere connection includes a carabiner 1 and an extension member 2. The carabiner 1 is used to connect force training equipment such as a gantry. The extension member 2 is used to extend the usage length of the carabiner 1 to suit different scenarios. The extension member 2 can be a chain or a high-strength rope with stainless steel rings at both ends. A suspension member 3 is suspended below the extension member 2, and multiple ropes 4 are suspended below the suspension member 3. The ropes 4 are folded in half, and their material is high-strength and can withstand the pulling force generated when the user uses them.

[0030] Among them, a restraint member 5 is slidably connected to the outer surfaces of the multiple ropes 4. The restraint member 5 is used to hold the sphere and lock the ropes 4 at the same time, preventing the sphere from rolling inside the multiple ropes 4 during use. Multiple elastic bands 6 are fixed to the lower sides of the outer surfaces of the multiple ropes 4. The elastic bands 6 are used to fix the position of the sphere wrapped by the multiple ropes 4 to prevent the sphere from leaking out through the gaps between the ropes 4. Two cooperating limiting members 7 are fixed to the lower ends of the multiple ropes 4. The two limiting members 7 can be opened to place different types of balls inside the multiple ropes 4.

[0031] Furthermore, as Figure 2 shown, the suspension member 3 includes a suspension ring 30. The suspension ring 30 is connected to the extension member 2 through a carabiner. A mounting circular plate 31 is fixed to the lower end of the suspension ring 30. Multiple suspension hooks 32 are slidably connected to one side of the upper end of the mounting circular plate 31 away from the center of the circle. The upper and lower sides of the suspension hooks 32 are arc-shaped. Fixed blocks 33 are fixed to the outer surfaces of the vertical parts of the multiple suspension hooks 32 on the side away from the center of the mounting circular plate 31. First springs 34 fixedly connected to the mounting circular plate 31 are fixed to the lower ends of the multiple fixed blocks 33. The first springs 34 are fixed between the fixed blocks 33 and the mounting circular plate 31. The first springs 34 are compression devices in the normal state, so that the fixed blocks 33 drive the suspension hooks 32 to receive a downward force.

[0032] In addition, a limiting ring 35 that cooperates with the multiple suspension hooks 32 is rotatably connected to the upper end of the mounting circular plate 31. Multiple card slots adapted to the suspension hooks 32 are opened on the upper end of the limiting ring 35. The suspension hooks 32 receive a downward force, causing the suspension hooks 32 to be stuck in the notches at the upper end of the limiting ring 35, so that the suspension hooks 32 will not slide on the upper surface of the limiting ring 35, ensuring the stability of the ropes 4 suspended below the suspension hooks 32.

[0033] Then, multiple mating grooves 36 are opened on the upper surface of the limiting ring 35. Second springs 37 are fixed to the bottom walls of the inner cavities of the multiple mating grooves 36. Multiple mating blocks 38 aligned with the upper surface of the limiting ring 35 are fixed to the upper ends of the multiple second springs 37. In the normal state, the upper surface of the mating block 38 is aligned with the upper surface of the limiting ring 35, as Figure 3As shown, when it is necessary to hang the rope 4, just rotate the limit ring 35 so that the corresponding hanging hook 32 is located inside one of the mating grooves 36, and then press down the mating block 38, so that the notch of the hanging hook 32 is exposed for hanging the rope 4.

[0034] Furthermore, as Figure 4 and Figure 5 shown, the restraint member 5 includes a frustum block 50. The inclined surface of the frustum block 50 is used to support the rope 4 to prevent multiple ropes 4 from being entangled. A connecting column 51 is fixed at the lower end of the frustum block 50. A pressing block 52 is slidably connected to the outer surface of the connecting column 51. A plurality of positioning blocks 53 are fixed on the outer surface of the pressing block 52. Two holes for installing the rope 4 are opened on the positioning blocks 53. The folded rope 4 passes through these two holes, which can limit the position of the rope 4. A plurality of triangular blocks 54 are fixed at the lower end of the pressing block 52. A connecting block 55 is fixed at the lower end of the pressing block 52. The upper side of the connecting block 55 is a cylinder and the lower side is a frustum;

[0035] Next, a rope-locking member 56 is fixedly connected to the outer surface of the connecting block 55. The rope-locking member 56 is used to lock the rope 4 so that the rope 4 can wrap the sphere. A plurality of springs 59 for supporting the pressing block 52 are fixed at the upper end of the rope-locking member 56. The springs 59 fix the position of the pressing block 52 in the normal state, so that the triangular blocks 54 do not affect the components in the rope-locking member 56;

[0036] Among them, as Figure 5 shown, a ball-catching block 57 is fixed to the lower side of the outer surface of the connecting block 55. The ball-catching block 57 is a frustum-shaped tube, and its outer surface is arc-shaped. The ball-catching block 57 is adapted to spheres of different diameters. The lower side of the ball-catching block 57 is a circular opening, which can be adapted to the surface of different spheres and is used to cover the outer surface of the sphere. A rope-passing ring block 58 is fixed to the outer surface of the ball-catching block 57. The rope-passing ring block 58 is used for the rope 4 to pass through, so that the restraint member 5 can slide on the surface of the rope 4.

[0037] Furthermore, as Figure 6 shown, the rope-locking member 56 includes an installation ring 5601, which is fixed to the outer surface of the upper cylinder of the connecting block 55. A plurality of groups of installation grooves 5602 are opened at the upper end of the installation ring 5601. Each group of installation grooves 5602 includes two symmetrically opened installation grooves 5602. A group of semi-cylindrical grooves 5602 are opened on the side wall of the inner cavity of each group of installation grooves 5602 away from the center of the installation ring 5601. Each group of semi-cylindrical grooves 5602 includes two. The diameter of the semi-cylindrical grooves 5602 is adapted to the diameter of the rope 4 for installing the rope 4. A group of installation springs 5603 are fixed to the side wall of the inner cavity of each group of installation grooves 5602 close to the center of the installation ring 5601. The two installation springs 5603 are respectively located in the inner cavities of the two installation grooves 5602 in the same group;

[0038] Next, at one end of each set of mounting springs 5603 away from the center of the mounting ring 5601, a set of rope clamping blocks 5604 is fixed. The two rope clamping blocks 5604 of each group slide in the inner cavities of the two mounting grooves 5602 of the same group. At one end of each set of rope clamping blocks 5604 away from the mounting spring 5603, a set of semi-cylindrical grooves II is provided. The semi-cylindrical groove I and the semi-cylindrical groove II are adapted to each other and can be used together to clamp the rope 4. A set of clamping posts 5605 is fixed in the inner cavity of each set of semi-cylindrical grooves II. A triangular block II 5606 is fixed at the upper end of each set of rope clamping blocks 5604. The triangular block II 5606 is jointly fixed at the upper ends of the two rope clamping blocks 5604 of the same group;

[0039] Among them, as Figure 7 shown, the triangular block II 5606 cooperates with the triangular block I 54. The cross-sections of the triangular blocks 5607 and the triangular block I 54 are right-angled triangles. The inclined surfaces of the triangular blocks 5607 and the triangular block I 54 are in contact. During the downward movement of the triangular block I 54, the triangular block I 54 moves downward along the inclined surface of the approaching triangular block 5607, causing the triangular block 5607 to move towards the center of the mounting ring 5601. As a result, the two rope clamping blocks 5604 of the same group connected to the triangular block II 5606 move towards the center of the mounting ring 5601, causing the semi-cylindrical groove I and the semi-cylindrical groove II to separate and no longer clamp the rope 4. The restraint member 5 can move on the surface of the rope 4, enabling the restraint member 5 to adapt to different types of balls.

[0040] Furthermore, as Figure 8 and Figure 9 shown, the limiting member 7 includes a semi-circular ring block 70. The outer surface of the semi-circular ring block 70 is fixedly connected to both ends of the rope 4, enabling the rope 4 to be hung on the hanging hook 32 after being folded in half. The connection between the rope 4 and the semi-circular ring block 70 is fixed with screws. If one of the ropes 4 is damaged, it can be replaced. A sliding groove 71 is provided on the outer surface of the semi-circular ring block 70. Two symmetric L-shaped clamping blocks 72 are fixed at the lower end of the semi-circular ring block 70. The two L-shaped clamping blocks 72 are respectively located at positions close to the two end faces of the sliding groove 71. A locking block 73 adapted to the L-shaped clamping blocks 72 is slidably connected in the inner cavity of the sliding groove 71. A groove adapted to the horizontal part of the L-shaped clamping block 72 is provided at the lower end of the locking block 73, enabling the locking block 73 to slide on the upper end of the horizontal part of the L-shaped clamping block 72.

[0041] It should be noted that the carabiner 1, the extension member 2, and the rope 4 in the present invention are all prior arts, and their installation methods and control methods are also conventional designs. The present invention will not be elaborated in detail.

[0042] The specific implementation manner of this device: This device is an auxiliary training device for sphere connection, mainly used to combine spheres of different diameters with a strength training device, facilitating the user to conduct training. At the same time, the spheres used in different sports can be replaced to improve the applicability of the device;

[0043] Specifically, when the device is in use, first slide the locking blocks 73 on the outer surfaces of the two semi-circular blocks 70 so that the two locking blocks 73 correspond to the end faces of the two semi-circular blocks 70 respectively. As Figure 8 shown, separate the two semi-circular blocks 70, stretch open the multiple elastic bands 6, place the sphere inside the multiple ropes 4, then align the end faces of the two semi-circular blocks 70, and rotate the locking blocks 73 on the outer surfaces of the two semi-circular blocks 70 so that the two locking blocks 73 slide into the inner cavities of the chute grooves 71 at the joints of the two semi-circular blocks 70 respectively. At the same time, the two L-shaped clamping blocks 72 on the same side are clamped, so that the two semi-circular blocks 70 form a ring, as Figure 10 shown, to support the lower side of the outer surface of the sphere;

[0044] Next, it is necessary to tighten the multiple ropes 4 to tightly wrap the sphere. By pressing the pressing block 52, the pressing block 52 drives the multiple triangular blocks one 54 at the lower end to move downward. During the downward movement of the multiple triangular blocks one 54, they will push the triangular blocks two 5606 that cooperate with them to move towards the center of the mounting ring 5601, as Figure 7 shown, so that the two rope clamping blocks 5604 connected to the triangular blocks two 5606 in the same group move towards the center of the mounting ring 5601. The two rope clamping blocks 5604 move away from the semi-cylindrical groove two, so that the semi-cylindrical groove one and the semi-cylindrical groove two are separated. The positioning posts 5605 in the inner cavity of the semi-cylindrical groove one no longer squeeze the rope 4, so that the rope passing ring block 58 can slide on the surface of the rope 4;

[0045] By sliding the rope passing ring block 58 to change the position of the ball clamping block 57, the ball clamping block 57 can cover the upper side of the outer surface of the sphere. Then release the pressing block 52, and the pressing block 52 resets under the action of the spring three 59, so that the multiple positioning posts 5605 clamp the rope 4 in the inner cavities of the semi-cylindrical groove one and the semi-cylindrical groove two again. In this way, the ball clamping block 57 cooperates with the limiting component 7 on the lower side of the outer surface of the sphere to clamp the sphere;

[0046] Next, as Figure 3 shown, hang the rope 4 on the hanging hook 32. By rotating the limiting ring 35 at the upper end of the mounting circular plate 31, the corresponding hanging hook 32 is located in the inner cavity of one of the mating grooves 36. Then press down the mating block 38, and the notch of the hanging hook 32 can be exposed to hang the rope 4. After the hanging is completed, push the hanging hook 32, and rotate the limiting ring 35 again so that the hanging hook 32 is located at the card slot at the upper end of the limiting ring 35. Then use the climbing buckle to hang the hanging ring 30 and the extension piece 2, and then connect the climbing buckle 1 to the cable of the strength training, and the device can be used for training.
