Technical Field
[0001] The utility model relates to the field of abdominal wheels, in particular to an abdominal wheel with adjustable extension. Background Art
[0002] An abdominal wheel is a fitness equipment for exercising the human abdomen. With the increasing emphasis on health by people, the demand for using abdominal wheels is also growing day by day. Among the applicable population, there are users of various physiques and ages, so the shoulder widths of users are different. However, the length of the elbow support part on the traditional abdominal wheel is fixed and unchanged, resulting in that the abdominal wheel cannot match the shoulder widths of some users. When users use an abdominal wheel that does not match their shoulder widths, it is extremely easy to cause sports injuries such as muscle strains and muscle overstrains, and there is a safety risk of falling and colliding. In order to reduce the occurrence of sports injuries and reduce this safety risk, the structure of the elbow support part on the abdominal wheel is optimized, and the elbow support part is adjusted into an extensible structure that can be extended and retracted to match the shoulder widths of different users. However, most elbow support parts are connected to the main body of the abdominal wheel on one side only, that is, only one side is fixed to the main body of the abdominal wheel, and the connection part between the elbow support part and the main body of the abdominal wheel forms a lever fulcrum, while the elbow support part forms a lever. As the elbow support part extends and moves, the vertical acting force to be borne at the lever fulcrum is greater, resulting in that this part is extremely easy to be damaged and broken during use. At the moment of damage and breakage, it is easy for the user to lose balance. After the user loses balance, in addition to being prone to falling and getting bruised, it is also easy for their head or chest to hit the main body of the abdominal wheel. If sharp structures such as pointed teeth appear after the lever fulcrum is damaged, it will also cause secondary injuries, and there are relatively large safety hazards. Summary of the Utility Model

[0023] The following further elaborates on the technical solution of the present utility model in conjunction with the specific embodiments, but does not constitute any limitation to the present utility model.
[0024] Example 1:
[0025] As Figures 1-4 shown, an adjustable ab wheel includes a main bracket 1, a handle 2 provided on the main bracket 1, and a main roller 3 for supporting the load. Elbow support parts 5 are respectively provided on two opposite sides of the main bracket 1. The elbow support parts 5 are slidably engaged with the main bracket 1 in a manner that the distance therebetween can be adjusted. A locking structure is provided between the elbow support parts 5 and the main bracket 1. The locking structure includes a locking member 7 and a mating part. The locking member 7 is detachably connected to the mating part. When the elbow support part 5 moves relative to the main bracket 1 to a set distance, the elbow support part 5 and the main bracket 1 are relatively fixed through the locking structure. Side rollers 4 for supporting the load are respectively provided on the two elbow support parts 5.
[0026] The working principle is that in this technical solution, a locking structure is provided between the main bracket 1 and the elbow support part 5. The elbow support part 5, the locking structure and the main bracket 1 are connected in sequence. The locking structure is equivalent to a physically lockable connector, providing a structure that can achieve real-time relative fixation for the relatively sliding elbow support part 5 and the main bracket 1. When the elbow support part 5 needs to perform an extended movement or a retracted movement, the locking member 7 is separated from the mating part and the two are no longer connected, making the elbow support part 5 and the main bracket 1 in a relatively sliding state. The elbow support part 5 can adjust its position on the ab wheel in real time according to requirements, that is, the position where the elbow support part 5 is located after completing the extended movement or the contracted movement; when the elbow support part 5 moves relative to the main bracket 1 to a set distance, that is, the elbow support part 5 moves to the required position on the ab wheel, the locking member 7 of the locking structure is connected to the mating part, making the elbow support part 5 and the main bracket 1 change from relative sliding to relative fixation. At this time, the elbow support part 5 is re-fixed on the main bracket 1. And no matter how far the elbow support part 5 moves relative to the main bracket 1 to different positions, the side rollers 4 will move synchronously with the elbow support part 5. The side rollers 4 always support the elbow support part 5, and the pressure received by the elbow support part 5 is directly applied to the plane through the side rollers 4, avoiding the elbow support part 5 from receiving a vertical force at the connection with the main bracket 1, realizing that the elbow support part 5 can be used after adjusting the distance in an extended movement manner on the ab wheel, and can also avoid being damaged by the force at the connection with the ab wheel main body due to the extended movement of the elbow support part 5.
[0027] In actual use, the locking member 7 can be provided on the main bracket 1 or on the elbow support part 5. When the locking member 7 is provided on the main bracket 1, correspondingly, the mating part is provided on the elbow support part 5. Conversely, when the locking member 7 is provided on the elbow support part 5, the mating part is provided on the main bracket 1.
[0028] In this embodiment, the locking member 7 is provided on the main bracket 1 and the mating part is provided on the elbow support part 5.
[0029] In some embodiments, the locking member 7 is a jacking member, which is connected to the main bracket 1 in a manner that can be adjusted by movement, and is connected to the mating portion in a separable manner through movement adjustment.
[0030] To implement the above solution, bolts or pins are often selected as the jacking member. In addition, in addition to bolts and pins, components such as screw rods and ejector rods can also be selected, and the embodiments do not impose too many restrictions on this.
[0031] When the ejector rod is a bolt, the bolt is threadedly connected to the main bracket 1 in an axially adjustable manner. Correspondingly, the mating portion is an abutting surface provided on the elbow support portion 5. By rotating the bolt on the main bracket 1, the bolt is tightened against the abutting surface, and the two are mutually pressed to form a frictional force, which prevents the elbow support portion 5 from sliding relative to the main bracket 1; conversely, by reversing the rotation of the bolt on the main bracket 1, the bolt is separated from the abutting surface, and the elbow support portion 5 and the main bracket 1 are in a relative sliding state; in addition, in addition to the abutting surface, a recess 8 can also be used for substitution. After the adjustment of the bolt on the main bracket 1 is completed, the bolt is inserted into the recess 8 to form a snap connection with the recess 8, thereby preventing the elbow support portion 5 from sliding relative to the main bracket 1; similarly, by controlling the knocking-in depth or pulling-out length of the pin on the main bracket 1, the pin abuts against the abutting surface (or is inserted into the recess 8), so that the elbow support portion 5 and the main bracket 1 are relatively fixed. Conversely, when the pin is separated from the abutting surface (or the recess 8), the elbow support portion 5 and the main bracket 1 are relatively slidable.
[0032] Preferably, the locking member 7 is a telescopically movable plug-in member. One end of the plug-in member is fixed on the main bracket 1, and the mating portion is a recess 8 provided on the elbow support portion 5. The opposite end of the plug-in member is connected to the recess 8 in a pluggable manner.
[0033] To implement the above solution, the plug-in member is often selected as a ball screw or a damper rod. In addition, spring telescopic components such as shock absorbers can also be used for substitution, and the embodiments do not impose too many restrictions on this.
[0034] Combined with Figure 2 、 Figure 3 and Figure 4As shown in the figure, when the ejector rod is a ball screw, the screw end of the ball screw is fixed on the main bracket 1, and the ball end abuts against the elbow. At this time, the balls on the ball end roll relative to the elbow support portion 5, and the elbow support portion 5 and the main bracket 1 are also in a relative sliding state; when the elbow support portion 5 moves to a preset distance, that is, the ball end of the ball is directly opposite to the concave portion 8, the balls are no longer squeezed, and the balls are pushed out by the spring inside the ball screw. Some of the balls enter the concave portion 8, and at this time, a clamping connection is formed, so that the elbow support portion 5 and the main bracket 1 are relatively fixed; when the elbow support portion 5 needs to be adjusted on the main bracket 1, by pulling the elbow support portion 5 with an external force, while driving the concave portion 8 to move, the inner side surface of the concave portion 8 squeezes the balls back into the ball screw, completing the separation of the balls from the concave portion 8. At this time, the elbow support portion 5 and the main bracket 1 are again in a relative sliding state; similarly, the movable ends of the damping rods all have buffer components such as rubber blocks. When the movable end of the damping rod is directly opposite to the concave portion 8, the movable end is no longer squeezed, and the restored deformation drives the buffer component to be squeezed into the concave portion 8. When the elbow support portion 5 needs to be adjusted on the main bracket 1, by pulling the elbow support portion 5 with an external force, while driving the concave portion 8 to move, the inner side surface of the concave portion 8 squeezes the buffer component to drive the movable end to retract, completing the separation of the balls from the concave portion 8.
[0035] As Figure 4 shown, in another preferred embodiment, the concave portion 8 is provided with a plurality of them, and they are arranged at intervals along the moving path of the elbow support portion 5. The plug is connected to any one of the concave portions 8 in a pluggable manner.
[0036] The setting of the plurality of concave portions 8 enables the elbow support portion 5 to have multiple set distances to choose from, enriching the selectivity of the stretching and moving distance of the elbow support portion 5. At the same time, it improves the coverage range of users with different shoulder widths, and enhances the diversification and practicality of the product.
[0037] As Figure 2 shown, in this embodiment, the main bracket 1 is provided with a guide rail 6 extending outward, the elbow support portion 5 is arranged on the guide rail 6, and is slidably matched with the guide rail 6 along the extending direction of the guide rail 6. The locking member 7 is arranged on the guide rail 6, and the mating portion is arranged on the elbow support portion 5.
[0038] The locking member 7 is arranged on the guide rail 6, which is convenient for hiding the locking member 7, improving the ornamental value, and at the same time avoiding the locking being exposed outside and being damaged by direct external force impact.
[0039] In some embodiments, the guide rail 6 is arranged on the elbow support portion 5, and the locking member 7 arranged on the guide rail 6 is detachably connected to the main bracket 1. This embodiment does not limit the setting position of the guide rail 6 too much.
[0040] As Figure 3As shown in the figure, the specific connection between the guide rail 6 and the elbow support part 5 is that a sliding cavity 51 matching the guide rail 6 is formed on the elbow support part 5. The guide rail 6 is arranged in the sliding cavity 51 and is slidably matched with the sliding cavity 51 along its length direction. A guide groove 61 extending along the axial direction of the guide rail 6 is formed on the guide rail 6. A slider 511 is arranged on the sliding cavity 51. The slider 511 is arranged in the guide groove 61 and is slidably matched with the guide groove 61 along the extending direction of the guide groove 61.
[0041] In some embodiments, the guide rail 6 is arranged on the elbow support part 5. Correspondingly, the sliding cavity 51 is formed on the main bracket 1. The embodiments are not overly limited in this regard.
[0042] As Figure 3 shown in the figure, in another preference, rib strips 62 are further arranged on the side surface of the guide rail 6. The rib strips 62 are in the same extending direction as the guide rail 6. A strip-shaped groove 512 matching the rib strips 62 is formed on the inner side of the sliding cavity 51. The rib strips 62 are arranged in the strip-shaped groove 512 and are slidably matched with the strip-shaped groove 512 along its extending direction.
[0043] There are two rib strips 62, which are respectively arranged on the opposite sides of the guide rail 6 and correspond to the side surfaces on the opposite sides of the guide rail 6. Correspondingly, two strip-shaped grooves 512 are formed on the inner side surface of the sliding cavity 51. The two strip-shaped grooves 512 correspond to the two rib strips 62 respectively, and the rib strips 62 are arranged in the corresponding strip-shaped grooves 512.
[0044] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
