[0001] The utility model relates to an abdominal training device. Background Art

[0002] The Chinese patent document with the announcement number CN218980363U discloses a double-wheel elbow-supported abdominal wheel, including a connecting frame, wheels and a support rod, and there are two wheels arranged on the front and rear sides of the connecting frame, and the bottoms of the two wheels are located in the same plane, the support rod is U-shaped, and the two sides of the inner wall of the support rod opening are connected to the left and right sides of the connecting frame; elbow support pieces are arranged on both sides of the outer wall of the support rod opening, and the abdominal exercise can be started by placing the elbow on the elbow support piece and holding the support rod with the hand. Therefore, the utility model makes the overall operation more stable through the arrangement of two wheels, and secondly, the arrangement of the elbow support piece increases a fulcrum, so that when exercising, the strength of the arm can be reduced and the strength can be converted to the elbow, thereby reducing the difficulty of exercise, and making it easier for beginners to do it. The scheme also specifically discloses: the wheel is provided with a mounting rod, and both ends of the mounting rod are connected to the connecting frame, an elastic member for increasing resistance is sleeved on the outer side of the mounting rod, and one end of the elastic member is connected to the inner wall of the wheel, and the other end of the elastic member is connected to the mounting rod, and both ends of the elastic member are expanded as the wheel rotates counterclockwise, and are compressed as the wheel rotates clockwise, and the elastic force is changed by setting the elastic member and cooperating with the rotation of the wheel to balance the force on the wheel.

[0003] However, the above solution cannot change the elastic force of the elastic member, and the resistance of the elastic member to the abdominal wheel when it slides forward and the assisting force when the abdominal wheel slides backward cannot be controlled, so the controllability is poor. Utility Model Content

[0004] The utility model aims to provide an abdominal training device with adjustable power-assistance.

[0005] The purpose of the utility model is achieved through the following technologies:

[0006] The adjusting mechanism is arranged on the rear supporting component, one end of the elastic rope is connected to the front supporting component, and the other end is connected to the adjusting mechanism, and the adjusting mechanism is used to adjust the length of the elastic rope between the front supporting component and the rear supporting component. The user can place the upper limbs on the front supporting component and the lower limbs on the rear supporting component, and operate the front supporting component to do abdominal exercises of leaning over and sliding forward and backward. When sliding forward, the front supporting component can stretch the elastic rope to make the elastic rope elastically deformed. By adjusting the length of the elastic rope between the front supporting component and the rear supporting component, the resistance of the elastic rope to the front supporting component when sliding forward can be increased or decreased, and the assistance provided by the elastic rope to the front supporting component when sliding backward can also be increased or decreased. By adjusting the length of the elastic rope between the front supporting component and the rear supporting component, it can also adapt to exercisers with different body shapes.

[0007] The adjusting mechanism includes a storage component, which can be rotatably or locked on the rear supporting component. The other end of the elastic rope is connected to the storage component. When the storage component rotates, the elastic rope can be stored on the storage component or released from the storage component. When the length of the elastic rope on the front supporting component and the rear supporting component needs to be increased, the storage component can be rotated to release the elastic rope. When the length of the elastic rope on the front supporting component and the rear supporting component needs to be shortened, the storage component can be rotated in the opposite direction to store the elastic rope on the storage component. The operation is convenient.

[0008] The adjusting mechanism further comprises an elastic member, wherein the top of the roll storage member is provided with a plurality of positioning grooves arranged at intervals around a circle, and the rear support member is provided with a plurality of positioning protrusions arranged at intervals around a circle which are matched with the positioning grooves. The roll storage member can be arranged on the rear support member to move up and down between a locking position and a rotatable position, and the elastic member drives the roll storage member to move upward to the locking position. When the roll storage member is in the locking position, the positioning groove and the positioning protrusion engage with each other to prevent the roll storage member from rotating. When the roll storage member is in the rotatable position, the positioning groove and the positioning protrusion separate from each other to prevent the roll storage member from rotating. In this way, when it is necessary to adjust the length of the elastic rope, it is only necessary to press the roll storage member downward to compress the elastic member, and the positioning protrusion disengages from the positioning groove, so that the roll storage member can be rotated. When the length of the elastic rope is adjusted to the desired length, the force applied to press down the roll storage member is cancelled, and the roll storage member is driven to the locking position by the elastic force of the elastic member, and the positioning protrusion and the positioning groove can engage with each other to restrict the roll storage member from rotating, so that the effect of quick adjustment can be achieved and the operation is convenient.

[0009] An operating portion is formed at the center of the top of the roll storage component, and an operating hole opposite to the operating portion is formed at the top of the rear support component. The operating hole allows a user to conveniently control the operating portion to operate the roll storage component.

[0010] The roll storage component includes a vertically extending limit rod, and the rear support component is formed with a limit hole for the lower end of the limit rod to pass through. The lower end of the limit rod is provided with a limit structure to prevent the limit rod from upwardly detaching from the limit hole, so that the roll storage component will not be driven by the elastic force of the elastic part to detach upward from the rear support component during installation, and the limit rod can also play a certain degree of guiding role when moving in the limit hole.

[0011] The elastic member is a coil spring, the coil storage component includes a positioning sleeve, the coil spring is sleeved on the positioning sleeve and is compressed between the coil storage component and the rear support component. The coil spring is sleeved on the positioning sleeve to facilitate product installation and prevent the coil spring from falling off.

[0012] The storage component includes a storage sleeve with an installation notch formed on the storage sleeve. One end of the elastic rope is connected to the front support component, and the other end passes through the installation notch and is provided with an anti-slip component larger than the installation notch, so that the elastic rope can be stored on the storage sleeve, and the anti-slip component can prevent the elastic rope from detaching from the storage sleeve.

[0013] The rear support component is provided with an annular positioning portion sleeved on the lower end of the storage sleeve. The annular positioning portion can play a positioning role when the product is installed, and can also limit the elastic rope on the storage sleeve.

[0014] It also includes two gripping handles, and the rear supporting component is provided with two adjusting mechanisms spaced apart on the left and right sides. A plurality of recessed portions corresponding to the positioning protrusions are formed on the top of the rear supporting component, and two plug-in portions that can be embedded in the recessed portions are formed on the bottom of the gripping handles. The gripping handles can be grasped by the user to perform push-up exercises, and the two plug-in portions can be embedded in the recessed portions at different angles to adjust the angles of the two gripping handles and perform different push-up exercises. The correspondence between the recessed portions and the positioning protrusions can make the structure more reasonable, more compact, and have lower production costs.

[0029] One end of the elastic rope 4 is connected to the front support component 2, and the other end is connected to the adjustment mechanism. A first installation notch 27 is formed at the rear end of the front support component 2, and two elastic ropes 4 are arranged at intervals. The elastic rope 4 is tubular, and the two ends of the elastic rope 4 are respectively provided with a first anti-slip component and a second anti-slip component 42. The size of the first anti-slip component is larger than the first installation notch 27. The first anti-slip component and the second anti-slip component 42 are specifically cylindrical wooden plugs, and the diameter of the wooden plugs is larger than the elastic rope 4. After installation, the first anti-slip component passes through the first installation notch 27 and is blocked by the first installation notch 27 to prevent the elastic rope 4 from detaching from the front support component 2.

[0030] The adjustment mechanism includes two symmetrically arranged ones. The adjustment mechanism is arranged on the rear support component 1. The adjustment mechanism is used to adjust the length of the elastic rope 4 between the front support component 2 and the rear support component 1. During the abdominal exercise, the front support component 2 slides forward to stretch the elastic rope 4 to make it elastically deformed. By adjusting the length of the elastic rope 4 between the front support component 2 and the rear support component 1, the resistance of the elastic rope 4 to the front support component 2 when sliding forward can be increased or decreased, and the assistance of the elastic rope 4 to the front support component 2 when sliding backward can also be increased or decreased. The adjustment mechanism includes a winding storage Part 3, the storage part 3 can be rotatably or locked on the rear support part 1, and the other end of the elastic cord 4 is connected to the storage part 3. When the storage part 3 rotates, the elastic cord 4 can be stored on the storage part 3 or released from the storage part 3. When it is necessary to increase the length of the elastic cord 4 on the front support part 2 and the rear support part 1, the storage part 3 is rotated to release the elastic cord 4. When it is necessary to shorten the length of the elastic cord 4 on the front support part 2 and the rear support part 1, the storage part 3 is rotated in the opposite direction to store the elastic cord 4 on the storage part 3. The operation is convenient.

[0031] The adjusting mechanism also includes an elastic member 36. A plurality of positioning grooves 31 arranged at intervals in a circumference are provided on the top of the roll storage component 3. The rear support component 1 includes a detachable cover plate 11 and a bottom plate 12. An operating portion 32 is formed at the top center of the roll storage component 3, and an operating handle 321 is formed at the center of the operating portion 32. The cover plate 11 is formed with an operating hole 114 opposite to the operating portion 32. The operating hole 114 is circular, and the operating portion 32 is also circular to match the operating hole 114. The operating hole 114 can be used to conveniently control the operating handle 321 to rotate the roll storage component 3. The operating hole 114 and the operating portion 32 are set to be circular to facilitate rotation. The cover plate 11 is formed with a plurality of positioning protrusions 112 arranged at intervals in a circumference to match the positioning grooves 31. The storage component 3 can be arranged between the cover plate 11 and the bottom plate 12 so as to be movable up and down between a locked position and a rotatable position. The elastic member 36 drives the storage component 3 to move upward to the locked position. When the storage component 3 is in the locked position, the positioning groove 31 and the positioning protrusion 112 are engaged with each other so that the storage component 3 cannot be rotated. When the storage component 3 is in the rotatable position, the positioning groove 31 and the positioning protrusion 112 are separated from each other so that the storage component 3 can be rotated. In this way, when it is necessary to adjust the length of the elastic rope 4, it is only necessary to press down the storage component 3 to compress the elastic member 36, and the positioning protrusion 112 is separated from the positioning groove 31, so that the storage component 3 can be rotated. When the length of the elastic rope 4 is adjusted to the desired length, the force applied to press down the storage component 3 is cancelled, and the storage component 3 is rotated by the elastic member 36. When the storage part 3 is driven to the locking position by elastic force, the positioning protrusion 112 and the positioning groove 31 can engage with each other to prevent the storage part 3 from rotating, which can achieve the effect of quick adjustment and is easy to operate. The elastic member 36 is a coil spring, and the storage part 3 is formed with a positioning sleeve 34.

One end of the elastic rope 4 passes through the first mounting notch 27 and the front support part The storage component 3 includes a limiting rod 37 extending vertically, and the rear support component 1 is formed with a limiting hole 124 for the lower end of the limiting rod 37 to pass through. The lower end of the limiting rod 37 is provided with a limiting structure to prevent the limiting rod 37 from upwardly escaping from the limiting hole 124. The limiting structure is a bolt 38 and a gasket 39. The limiting rod 37 is formed with a screw hole. After the limiting rod 37 is inserted into the limiting hole 124, the bolt 38 is connected to the limiting rod, and the gasket 39 is used to prevent the limiting rod 37 from upwardly escaping from the limiting hole 124. In this way, the storage component 3 will not be driven by the elastic force of the elastic member 36 to detach upward from the rear support component 1 during installation.Furthermore, the movement of the limiting rod 37 in the limiting hole 124 can also play a guiding role to a certain extent.

[0032] An annular positioning portion 121 is formed on the bottom plate 12 and is sleeved on the lower end of the winding sleeve 35 . The annular positioning portion 121 can play a positioning role when the product is installed, and can also limit the elastic rope 4 on the winding sleeve 35 .
