[0003] The sliding part of the above solution is set on the base. When in use, the force exerted by the user on the sliding part directly acts on the base. The base may be easily deformed or worn after long-term use, and the sliding part cannot directly contact the ground when moving back and forth, and the stability is not strong enough. Utility Model Content

[0004] The purpose of the utility model is to provide a track abdominal fitness device with a more stable structure and a long service life.

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

[0006] A track abdominal fitness device includes an abdominal fitness mechanism and a track frame, and is characterized in that: the abdominal fitness mechanism includes a walking part and a supporting part, the walking part includes a rotatable walking wheel, the walking wheel enables the abdominal fitness mechanism to be movably supported on the ground, and the track frame includes a track for guiding the abdominal fitness mechanism to move back and forth on the ground. In this way, when the user uses the abdominal fitness mechanism to move along the track, because the walking wheels can be supported on the ground, the user's weight will not generate downward pressure on the track frame or only generate a small pressure on the track frame. The track frame will not be deformed or damaged due to the user's long-term downward pressure on the abdominal fitness mechanism. The structure is more reasonable and the service life is long. In addition, the movement of the walking wheels on the ground can make the back and forth movement of the abdominal fitness mechanism more stable and smooth.

[0007] The walking component includes a wheel frame and the walking wheel. The walking wheel is rotatably set on the wheel frame through a wheel axle, the wheel axle is fixed on the wheel frame, and the walking wheel is rotatably set on the wheel axle. An assist torsion spring is provided in the walking wheel, one end of the assist torsion spring is fixed on the wheel axle and the other end is fixed on the walking wheel. When the user uses the abdominal fitness mechanism to exercise, pushing the abdominal fitness mechanism forward will provide a certain resistance to the walking wheel, and will provide rebound assistance when retracting the abdominal fitness mechanism backward, thereby achieving the effect of assisting recovery and improving a certain degree of safety.

[0008] The walking component includes two wheel frames spaced apart on the left and right sides, each wheel frame is provided with at least one walking wheel, and the supporting component includes two elbow support components provided on the top of the two wheel frames.

[0009] The track frame includes two tracks, and the two tracks are used to guide the two wheel frames to move forward and backward respectively. The movement of the abdominal fitness mechanism can be more stable through the track.

[0011] Removable pins are provided at both ends of the connecting rod, and pin holes for the pins to pass through are formed at both ends of the connecting rod. The pins pass through the pin holes in a direction perpendicular to the length of the connecting rod to limit the connecting rod from being separated from the wheel frame. The use of pin connection can facilitate disassembly and assembly, and the user only needs to pull out the pins to pull out the connecting rod.

[0012] The support component also includes a connecting component that is detachably connected between the two elbow support components. The connecting component can connect the two elbow support components together so that the two support components can move synchronously. The connecting component can also be removed to allow the two support components to move asynchronously, and the user can choose different exercise methods.

[0013] The elbow support component is provided with a slot extending forward and backward, an insertion port is formed at one end of the slot, and the other end is closed, and an avoidance port is formed on the side of the slot, and the avoidance port is a necked structure. The connecting component is provided with an insertion portion that can be inserted into the slot and adapted to the shape of the slot. When connecting, it is only necessary to insert the insertion portion of the connecting component into the slot from the insertion port. This makes the disassembly and assembly of the connecting component more convenient and the connection strength is high. The closure of one end of the slot can prevent the insertion portion from detaching from the slot from the other end.

[0014] The slots are provided on both the left and right sides of the elbow support component, and the front and rear ends of the elbow support component are provided with front plug-in holes and rear plug-in holes for installing armrests. The support component also includes an armrest provided in the front plug-in hole or the rear plug-in hole. When the user's elbow is supported on the elbow support component, the hand can grasp the armrest. In this way, there is no need to distinguish the direction of the elbow support component when connecting the elbow support component to the connecting component and when installing the armrest, which reduces the difficulty of installation and speeds up the installation.

[0015] The support component further comprises an armrest provided on the elbow support component. When the user supports his elbow on the elbow support component, his hands can grasp the armrest.

[0016] The wheel frame includes two side frames arranged at intervals on the left and right sides, and the running wheel is rotatably arranged between the two side frames. The structure of the two side frames can facilitate the installation of the running wheel.

[0017] The wheel frame is provided with a clearance opening for the track to pass through, and the abdominal strengthening mechanism is provided with at least two guide wheels located on both sides of the track. The guide wheels are rotatably set on the abdominal strengthening mechanism and in rolling contact with the track, so that the wheel frame can move well on the track, and the guide wheels are used to guide the track to pass through the clearance opening to reduce wear.

[0018] The track is composed of multiple track sections that can be detachably connected, so that the abdominal fitness mechanism can be detached from the track and used independently.

[0019] The track split is a tubular structure.

[0033] Reference Figures 1 to 12As shown, a track abdominal fitness device includes an abdominal fitness mechanism 1 and a track frame 6. The abdominal fitness mechanism 1 is used for the user to bend over and drive it to move forward and backward to exercise the abdominal muscles. The abdominal fitness mechanism 1 includes a walking part and a supporting part. The walking part includes a rotatable walking wheel 22. The walking wheel 22 enables the abdominal fitness mechanism 1 to be movably supported on the ground. The track frame 6 includes a track for guiding the abdominal fitness mechanism 1 to move forward and backward on the ground. The track frame 6 specifically includes a track, two support rods 62 arranged at intervals front and back and extending laterally, and a transition rod 64 connected between the two ends of the track and the support rods. The track is specifically two circular tubes 61 arranged in parallel and at intervals. The support rods 62 are used to support the two circular tubes 61 on the ground. The transition rods 64 can keep the two circular tubes 61 away from the ground and not in contact with the ground. Two reinforcing rods 63 are also provided between the two circular tubes 61 to strengthen the strength of the track frame 6. The circular tubes 61, the support rods 62, the transition rods 64 and the reinforcing rods 63 are connected by welding, and anti-slip sheets 65 are also provided at the bottom of the two support rods 62. When the user uses the abdominal fitness mechanism 1 to move along the track, because the walking wheels 22 can be supported on the ground, the user's weight will not produce downward pressure on the track frame 6 or only produce a small pressure on the track frame 6. The track frame 6 will not be deformed or damaged due to the user's long-term downward pressure on the abdominal fitness mechanism 1. The structure is more reasonable and has a long service life. In addition, the movement of the walking wheels 22 on the ground can make the forward and backward movement of the abdominal fitness mechanism 1 more stable and smooth. The track is composed of multiple sections of detachable tracks, specifically as follows: Figure 5 and Figure 6 As shown, the circular tube body 61 is composed of multiple detachable tube segments, an insertion segment is provided at the end of one of the two adjacent tube segments, and a splicing segment is provided at the end of the other side for the insertion segment to be inserted, a retractable spring buckle is provided on the side of the insertion segment, and the splicing segment is provided with a buckle hole for the spring buckle to be embedded. When connecting, it is only necessary to connect the insertion segment and the splicing segment of the two tube segments, and snap the spring buckle into the buckle hole. The disassembly and assembly are quick and convenient. The spring buckle is a prior art and will not be described in detail here. The purpose of setting the circular tube body 61 as a multi-section detachable structure is that the user can choose to disassemble the abdominal fitness mechanism 1 from the track frame 6 according to his own wishes, and use the abdominal fitness mechanism 1 alone for exercise without being restricted by the track.

[0034] The walking part includes two wheel frames 21 spaced apart on the left and right sides. Each wheel frame 21 is provided with two walking wheels 22 arranged front and back. The walking wheels 22 are rotatably arranged on the wheel frame 21 through the wheel axle 221. The wheel frame 21 includes two side frames 213 spaced apart on the left and right sides. The two side frames 213 are detachably connected by screws. The walking wheels 22 are rotatably arranged between the two side frames 213. The structure of the two side frames 213 can facilitate the installation of the walking wheels 22. Mounting holes 215 are formed on both side frames 213. A detachable connecting rod 5 is provided between the two wheel frames 21 in a direction perpendicular to the length of the track. The connecting rod 5 passes through the mounting holes 215 on the two side frames 213 of the two wheel frames 21 to connect the two wheel frames 21 together, so that the overall connection strength of the abdominal fitness mechanism 1 is stronger. Figure 9 As shown, both ends of the connecting rod 5 are formed with latch holes 52 and are provided with latches 51. The latches 51 pass through the latch holes 52 in a direction perpendicular to the length of the connecting rod 5 to limit the connecting rod 5 from being separated from the wheel frame 21. A pull ring 53 is also provided on the latch 51 to facilitate the user to pull the latch 51. The use of the latch 51 for connection can facilitate disassembly and assembly. The user only needs to pull out the latch 51 to pull out the connecting rod 5. The outer peripheral surface of the wheel frame 21 is formed with a latch installation groove 218, which can play a certain guiding role in the installation of the latch 51 and also increase a certain aesthetics.

[0035] The walking wheel 22 is a cylindrical structure, and an assist torsion spring 222 is provided inside thereof, and one end of the assist torsion spring 222 is fixed to the wheel axle 221 and the other end is fixed to the walking wheel 22. Both ends of the wheel axle 221 are fixedly connected to the wheel frame 21 by fastening nuts. A positioning rod 223 is fixedly provided on the wheel axle 221, and one end of the assist torsion spring 222 is fixed to the positioning rod 223, and the other end is fixed to the inner wall of the walking wheel 22. When the user uses the abdominal fitness mechanism 1 for exercise, the abdominal fitness mechanism 1 is pushed forward, and one end of the assist torsion spring 222 will rotate with the walking wheel 22. Because the other end is fixed to the wheel frame 21, the assist torsion spring 222 will deform, providing a certain resistance to the walking wheel 22, and providing rebound assistance when the abdominal fitness mechanism 1 is retracted backward, thereby achieving the effect of assisting recovery and improving a certain degree of exercise safety.

[0036] The supporting member includes two elbow support members 3 arranged on the top of the two wheel frames 21 and a connecting member 4 detachably connected between the two elbow support members 3, such as Figure 10 As shown, the connecting member 4 can connect the two elbow support members 3 together, so that the support members can move synchronously, as shown in FIG. Figure 11 As shown, the connecting member 4 and the connecting rod 5 can also be removed to separate the supporting member into two parts for asynchronous movement, and the user can operate the left and right elbow support members 3 to move back and forth alternately, as shown in FIG. Figure 12As shown, the wheel frame 21 on one side, the two walking wheels 22 provided on the wheel frame 21, and the connecting rod 5 can also be removed and used separately. The connecting rod 5 is inserted into the installation hole 215 of the wheel frame 21 and extends from both sides of the wheel frame 21 to serve as a grip rod. In this way, it can also be used as a traditional grip-type abdominal wheel. Users can choose different exercise methods, and it is more functional and practical.

[0037] A protrusion 33 is formed on the opposite side of the two elbow support parts 3, and a slot 331 extending forward and backward is formed on the protrusion 33. One end of the slot 331 has an insertion opening and the other end is closed. The slot 331 is a T-shaped slot with a lateral avoidance opening. Both ends of the connecting part 4 are formed with an insertion part 41 with a T-shaped cross-section that can be inserted into the slot 331 and adapted to the slot 331. When connecting, it is only necessary to insert the insertion parts 41 at both ends of the connecting part 4 into the slot 331 of the two elbow support parts 3. There is no need to distinguish the front and back directions of the elbow support parts 3 when connecting the elbow support parts 3 and the connecting part 4, which reduces the difficulty of installation, speeds up the installation speed, and makes disassembly and assembly more convenient. The support component also includes armrests 31 provided on the two elbow support components 3. When the user supports his elbows on the elbow support components 3, his hands can grasp the armrests 31. Buffer pads 32 are provided on the tops of the two elbow support components 3. The buffer pads 32 can make the user's exercise more comfortable. A front plug-in hole is formed at the front end of the elbow support component 3, and a rear plug-in hole is formed at the rear end. In this way, when installing the armrests 31, there is no need to distinguish the front and rear directions of the elbow support component 3, and the installation is simple and convenient.

[0038] The wheel frame 21 is formed with a clearance opening 211 for the circular tube 61 to pass through. The wheel frame 21 is a hollow structure with a reinforced rib plate. Four guide wheels 212 are provided in this hollow structure, symmetrically arranged on both sides of the track. This allows the wheel frame 21 to move smoothly on the track. The guide wheels 212 are used to guide the circular tube 61 through the clearance opening 211 to reduce wear. The wheel frame 21 is formed with a guide wheel mounting portion 216. The guide wheel mounting portion 216 is provided with a rotating shaft 214. The rotating shaft 214 is arranged vertically. The guide wheel 212 is sleeved on the rotating shaft 214 and is horizontally arranged in the guide wheel mounting portion 216 through the rotating shaft 214 to guide the circular tube 61. The toggle support component 3 and the wheel frame 21 are integrally injection molded for easy production.

[0039] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention.
