There are many types of outdoor fitness equipment, which can be roughly divided into strength equipment, rebound equipment, agility equipment, flexibility equipment, endurance equipment, etc.

[0003] After searching, a Chinese patent with publication number CN214286531U discloses a leg exercise device for internal medicine care of the elderly, including a support base and handrails connected to both sides of the top of the support base. Both ends of the support base are provided with locking mechanisms for avoiding injuries to the elderly's legs through self-locking ability when the elderly's legs suddenly become weak. This leg exercise device for internal medicine care of the elderly is different from the existing technology, so that when the elderly exercise, they will not be hit by the exercise bar when it falls due to sudden weakness of the legs, thereby avoiding accidental injuries to the elderly. Through the locking mechanism, under the control of the self-locking part to rotate, when the elderly feel that their legs are weak, they quickly press the clamping part to lock the rotating part, thereby ensuring the personal safety of the elderly when using the equipment for exercise.

[0004] However, in the above technical solution, the leg muscles of the human body are trained only by the deadweight of the exercise bar, and the weight required for the exercise comes from the deadweight of the exercise bar. Different people have different health conditions and leg strengths. The weight of the exercise bar cannot be adjusted according to the exercise requirements of different people, which brings certain limitations to the use of the equipment. Utility Model Content

[0005] The utility model aims to provide an outdoor strength training device in view of the problems existing in the background technology.

[0006] The technical solution of the utility model is an outdoor strength training device, comprising a support base, symmetrically arranged handles are connected to the two sides of the support base, a seat back is connected to the other side of the support base, and a training mechanism capable of training leg strength is provided on the support base;

[0007] The exercise mechanism comprises an exercise component and an adjustment component. The exercise component can rotate at a certain angle to exercise the leg strength of the human body. The adjustment component is symmetrically arranged on both sides of the exercise component and can adjust the resistance of the exercise component.

[0008] Preferably, the exercise assembly includes a rotating rod, a rotating shaft, a clamping plate, a steel cable, a pulley and a counterweight. A support seat is connected to a protrusion on the side away from the seat back, and a through hole is provided on the protrusion for rotatably connecting to the rotating shaft. The rotating rod is connected to one end of the rotating shaft, and the opposite side of the rotating rod is connected to an arc-shaped clamping plate. The rotating rod is connected to one end of the steel cable, and the other end of the steel cable is connected to the counterweight. The pulley connected to the support seat is used for winding the steel cable.

[0009] Preferably, the inner walls of the clamping plates are connected with protective pads.

[0010] Preferably, a receiving box for sliding connection with the counterweight is connected to the support seat, and a rubber pad is connected to the bottom surface of the receiving box.

[0011] Preferably, baffles are connected to both sides of the support seat, arc-shaped guide grooves are formed on the baffles, and the guide grooves are slidably connected to guide blocks connected to the rotating rod.

[0012] Preferably, the adjustment assembly includes a fixed cylinder, an adjustment handle, a threaded rod, a rotating disk and a friction plate. The fixed cylinder is connected to the protrusion. A threaded hole for connecting the threaded rod is provided on the fixed cylinder. One end of the threaded rod passes through the threaded hole and is connected to the friction plate. The friction plate is slidably connected to the rotating disk connected to the rotating shaft. The other end of the threaded rod is connected to the adjustment handle.

[0013] Preferably, a dial is adhered to the fixed cylinder, a connecting rod is connected to the friction plate, and the connecting rod passes through a through hole on the fixed cylinder to connect to the pointer.

[0014] Compared with the prior art, the above technical solution of the utility model has the following beneficial technical effects:

[0015] The utility model can adjust the exercise intensity required by different exercise equipment users. By rotating the adjusting handle, the friction plate installed on the threaded rod can be gradually brought close to the rotating disk. The friction force of the friction plate will cause the rotation of the rotating disk to be blocked by different resistances. The leg movement of the human body drives the rotating rod, the rotating shaft and the rotating disk to rotate along the rotating shaft to exercise the leg muscles. The resistance of the friction plate means that when the human leg is weak, the rotating disk is still restricted by the friction plate, thereby preventing the rotating rod from quickly recovering and colliding with the human body.

DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] like Figure 1-Figure 4 As shown, the utility model provides an outdoor strength training device, comprising a support base 1, symmetrically arranged handles 2 are connected to both sides of the support base 1, a seat back 3 is connected to the other side of the support base 1, and a training mechanism capable of training leg strength is provided on the support base 1;

[0023] The exercise mechanism comprises an exercise component and an adjustment component. The exercise component can rotate at a certain angle to exercise the leg strength of the human body. The adjustment component is symmetrically arranged on both sides of the exercise component and can adjust the resistance of the exercise component.

[0024] The utility model can adjust the exercise intensity required by different exercise equipment users. By rotating the adjusting handle 17, the friction plate 20 installed on the threaded rod 18 can be gradually brought close to the rotating disk 19. The friction force of the friction plate 20 will cause the rotation of the rotating disk 19 to be blocked by different resistances. The leg movement of the human body drives the rotating rod 4, the rotating shaft 5 and the rotating disk 19 to rotate along the rotating shaft 5 to exercise the leg muscles. The resistance of the friction plate 20 means that when the human leg is weak, the rotating disk 19 is still restricted by the friction plate 20, thereby avoiding the rotating rod 4 from quickly recovering and hitting the human body.

[0025] Embodiment 2

[0026] like Figure 1-Figure 3As shown, the utility model proposes an outdoor strength training device. Compared with the first embodiment, in this embodiment, the training assembly includes a rotating rod 4, a rotating shaft 5, a clamping plate 6, a steel cable 7, a pulley 8 and a counterweight 9. A support seat 1 is connected with a protrusion on the side away from the seat back 3. The protrusion is provided with a through hole for rotating and connecting the rotating shaft 5. The rotating rod 4 is connected to one end of the rotating shaft 5. The rotating rod 4 is connected to the arc-shaped clamping plate 6 on the opposite side of the rotating rod 4. The rotating rod 4 is connected to one end of the steel cable 7. The other end of the steel cable 7 is connected to the counterweight 9. The pulley 8 connected to the support seat 1 is used to wind the steel cable 7. When a person uses the device for exercise, the human body sits on the support seat 1, and the legs are placed in the arc-shaped clamping plate 6. The leg force drives the clamping plate 6 and the rotating rod 4 to rotate with the axis of the rotating shaft 5 as the center. The rotating rod 4 pulls the counterweight 9 to move through the movement of the steel cable 7 on the pulley 8. The leg muscle force drives the counterweight 9 to move, so that the leg muscle strength is exercised.

[0027] The inner wall of the clamping plate 6 is connected with a protective pad 10. The protective pad 10 is made of a softer material such as rubber or sponge to protect the legs during exercise and prevent the corners of the clamping plate 6 from injuring the human body.

[0028] The support seat 1 is connected with a storage box 11 for sliding connection with the counterweight 9, and a rubber pad 12 is connected to the bottom of the storage box 11. The counterweight 9 slides in the storage box 11 when pulled by the steel cable 7. The storage box 11 guides the counterweight 9 and can play a certain anti-theft role to prevent the metal counterweight 9 from being lost. The rubber pad 12 plays a buffering and noise reduction role when the counterweight 9 falls into the bottom of the storage box 11, avoiding excessive noise affecting the exercise experience.

[0029] Baffles 13 are connected to both sides of the support seat 1. Arc-shaped guide grooves 14 are provided on the baffles 13. The guide grooves 14 are slidably connected to guide blocks 15 connected to the rotating rod 4. When the rotating rod 4 rotates, the guide blocks 15 on it slide along the arc-shaped guide grooves 14, and the guide grooves 14 limit the rotation of the guide blocks 15.

[0030] Embodiment 3

[0031] like Figure 4As shown, the utility model proposes an outdoor strength training device. Compared with the second embodiment, in this embodiment, the adjustment component includes a fixed cylinder 16, an adjustment handle 17, a threaded rod 18, a rotating disk 19 and a friction plate 20. The fixed cylinder 16 is connected to the protrusion. The fixed cylinder 16 is provided with a threaded hole for connecting the threaded rod 18. One end of the threaded rod 18 passes through the threaded hole and is connected to the friction plate 20. The friction plate 20 is slidably connected to the rotating disk 19 connected to the rotating shaft 5. The other end of the threaded rod 18 is connected to the adjustment handle 17. When the adjustment handle 17 is rotated, the threaded rod 18 is driven to rotate. The friction plate 20 on the threaded rod 18 moves along the axis of the threaded rod 18. The friction plate 20 gradually approaches the rotating disk 19. The resistance of the friction plate 20 to the rotating disk 19 makes the counterweight 9 subject to additional restrictions when moving, thereby obtaining a stronger resistance so that the user of the device can exercise with a heavier weight.

[0032] A scale plate 21 is attached to the fixed cylinder 16, and a connecting rod 22 is connected to the friction plate 20. The connecting rod 22 passes through the through hole on the fixed cylinder 16 and is connected to the pointer 23. When the friction plate 20 rotates, the connecting rod 22 drives the pointer 23 to rotate, so that the condition of the friction plate 20 and the current corresponding weight can be viewed to adjust the subsequent exercise.

[0033] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
