[0071] As Figure 1 With Figure 2 As shown in some embodiments, the trainer further comprises a connecting member 11, one end of the connecting member 11 is connected with the pull rope 10, and the other end is detachably connected with the connecting hole 7, so that the user can connect the pull rope 10 with any connecting hole 7 on the carriage assembly through the connecting member 11, so as to change the connection position of the pull rope 10 and the carriage assembly.

[0072] In some embodiments, the connecting member 11 further comprises a fixed part and a movable part, one end of the fixed part is connected with the pull rope 10, and the other end is bent and extended to pass through the connecting hole 7, one end of the movable part is rotatably arranged on the fixed part, and the other end is rotatably connected with the fixed part to form a closed ring, or is rotatable to open the closed ring.

[0073] Specifically, one end of the fixed part is connected with the pull rope 10, and the other end is bent and extended to pass through the connecting hole 7 to form a ring member with a notch, and the notch is located between the two ends of the fixed part.

[0074] The movable part is arranged at the notch of the fixed part, one end of the movable part is rotatably arranged on the fixed part as a rotating end, and the other end is rotatable relative to the rotating end, and is connected with the fixed part to form a closed ring when rotated to a certain position, at which time the pull rope 10 is connected with the connecting hole 7 through the connecting member 11.

[0075] Alternatively, the other end of the movable part is rotatable relative to the rotating end to open the closed ring, and the connecting member 11 is detached from the connecting hole 7 through the notch, at which time the pull rope 10 is disconnected from the connecting hole 7 through the connecting member 11.

[0076] In some embodiments, the trainer further comprises a reset member arranged between the fixed part and the movable part to push the movable part to rotate under the elastic force, so as to connect the fixed part to form a closed ring.

[0077] Specifically, the reset member includes but is not limited to a spring, a rubber, and a spring piece, and the reset member is arranged between the fixed part and the movable part, one end of the reset member abuts against the fixed part, and the other end abuts against the movable part.

[0078] When an external force pushes the movable part to rotate relative to the fixed part based on the movable end thereof, the reset member is compressed to store elastic potential energy, and the closed ring is opened, at which time the user can detach the connecting member 11 from the connecting hole 7 through the notch.

[0079] When the external force is unloaded, the reset member releases the stored elastic potential energy to push the movable part to rotate relative to the fixed part based on the movable end thereof until a certain position at which the fixed part is connected to form a closed ring, at which time the pull rope 10 is connected with the connecting hole 7 through the connecting member 11.

[0080] The reset member is used to push the movable part to rotate relative to the fixed part, so that the reset process of the movable part does not need external force interference, and the disassembly efficiency of the connecting member 11 is improved.

[0081] As shown in Figures 1 to 4 some embodiments, the trainer further comprises a clamping member 12, which is arranged between and connected with the connecting member 11 and the pull rope 10, and is used to adjust the connection position of the connecting member 11 and the pull rope 10.

[0082] Specifically, the clamping member 12 further comprises a mounting part and two rotating parts, the two rotating parts are arranged on the mounting part in meshing and rotating manner, and the relative rotating directions of the two rotating parts are opposite and are one-way locked, that is, one of the rotating parts is only allowed to rotate in the counterclockwise direction, and the other rotating part is only allowed to rotate in the clockwise direction; conversely, one of the rotating parts is only allowed to rotate in the clockwise direction, and the other rotating part is only allowed to rotate in the counterclockwise direction.

[0083] The pull rope 10 is arranged between the two rotating parts, and the two rotating parts control the passing of the pull rope 10 through the position of meshing contact. When the pull rope 10 moves in the first direction, the two rotating parts rotate relatively to allow the pull rope 10 to pass; however, when the pull rope 10 moves in the opposite direction of the first direction, the two rotating parts cannot rotate relatively due to one-way locking, thereby locking the pull rope 10 and not allowing it to move in the opposite direction of the first direction.

[0084] The clamping member 12 is used to adjust the connection position of the pull rope 10 and the connecting member 11, thereby further accurately adjusting the connection position of the pull rope 10 and the carriage assembly, so that the length of the pull rope 10 is kept at a position most suitable for the user's body data.

[0086] Specifically, the two transmission arms 13 are oppositely arranged on the base 1, one end of the transmission arm 13 is arranged on the base 1, the other end extends along the length direction of the slide rail 2 and is rotatably connected with the rope winding member 14, and the rope winding member 14 is used to wind the pull rope 10.

[0087] The first motor is arranged in the base 1, the output end of the first motor is connected with the two rope winding members, and the first motor is turned on to drive the two rope winding members to rotate relative to the transmission arm 13, thereby winding the pull rope 10.

[0088] It should be noted that when the resistance assembly includes the controller and the second motor, the first motor is electrically connected with the controller, and when the controller closes the second motor, the controller sends an electrical signal to the first motor, and the first motor starts to drive the rope winding member to wind the rope until it stops running after a predetermined period of time, thereby improving the storage efficiency of the rope 10.

[0089] In some embodiments, the trainer further includes an adjusting assembly disposed on the stand 8 and connected with the direction-changing member 9, for adjusting the distance between the direction-changing member 9 and the base assembly.

[0090] Specifically, the direction-changing member 9 includes but is not limited to a roller or a drum, and is used to provide a direction-changing point to change the direction of the pulling force of the rope 10, thereby supporting the user to pull the rope 10 at different angles for training.

The locking member 16 is disposed inside the stand 8, and the locking member 16 is provided with at least two locking holes 20. The two locking holes 20 are communicated. One end of the adjusting member 17 is provided through the mounting seat 15, and the other end is provided through the opening on the side wall of the stand 8 to extend into or out of the locking hole 20, so as to correspondingly lock or release the relative position of the mounting seat 15 and the stand 8. One end of the pushing member 18 is slidingly disposed in the adjusting member 17, and the other end is provided through the other opening on the side wall of the stand 8 and connected with the mounting seat 15. The resilient member 19 is disposed between the pushing member 18 and the adjusting member 17.

[0093] Specifically, the stand 8 is hollow inside for mounting the locking member 16. The locking member 16 is provided with at least two locking holes 20. The two locking holes 20 are communicated through the avoiding opening. The inner diameter of the locking hole 20 is greater than the transverse inner diameter of the avoiding opening.

[0094] The mounting seat 15 is slidingly sleeved on the outside of the stand 8, and the direction-changing member 9 is disposed on the mounting seat 15 to slide relative to the stand 8 in the direction away from or close to the base 1.

[0096] When the positioning part extends into the locking hole 20, the mounting seat 15 is locked relative to the stand 8 because the outer diameter of the positioning part is greater than the transverse inner diameter of the avoiding hole.

[0097] When the positioning part is pulled out of the locking hole 20, the mounting seat 15 and the stand 8 are relatively slid through the connecting part between the pressing part and the positioning part sliding in the avoiding hole through the opening in the side wall of the stand 8, until the positioning part extends into another locking hole 20.

[0098] The pushing member 18 comprises a stabilizing part, a pushing part and an extension part, wherein one end of the extension part is slidably arranged in the connecting part, and the other end is connected to the stabilizing part, the stabilizing part is arranged on the mounting seat 15, and the pushing part is fixed on the extension part and located between the stabilizing part and the positioning part.

[0099] The elastic member 19 is sleeved on the extension part and located between the pushing part and the positioning part, and the elastic member 19 includes but is not limited to a compression spring, rubber and a spring sheet. The elastic member 19 is used to push the adjusting member 17 to reset and save the reset action.

[0100] When the pressing part is pushed by an external force to make the positioning part extend out of the locking hole 20, the extension part slides into the connecting part, the distance between the positioning part and the pushing part becomes smaller, the elastic member 19 is compressed to store elastic potential energy, and at this time, the connecting part is allowed to slide into the avoiding hole, so that the sliding seat 3 can slide along the stand 8 in the direction away from or close to the base 1, so as to change the distance between the direction-changing member 9 on the sliding seat 3 and the base 1.

[0101] When the external force is unloaded, the elastic member 19 releases the elastic potential energy, the extension part slides out of the connecting part, the distance between the positioning part and the pushing part is pushed apart by the elastic member 19 to make the positioning part extend into the locking hole 20, at this time, the connecting part is not allowed to slide into the avoiding hole, the mounting seat 15 is locked relative to the stand 8, so as to lock the distance between the direction-changing member 9 and the base 1.

[0102] In summary, the application provides a trainer. A plurality of connecting holes 7 are arranged on the sliding assembly, and the connecting holes 7 are arranged based on the direction close to or away from the stand 8.
