Claims

1. A folding rowing machine characterized in that, include: Main framework; A slide rail frame is provided with a first hinge end, which is hinged to the main frame to form a hinge structure, so that the slide rail frame has an unfolded state and a folded state relative to the main frame through the hinge structure. A locking and unlocking mechanism is operably disposed on the hinge structure to lock or unlock, and the locking and unlocking mechanism further includes an operating element for performing the locking or unlocking action; The handle is fixedly connected to either the main frame or the slide rail frame; The operating component has an operating part, and the positional distance between the operating part and the handle part is configured such that the distance between them is sufficient for the operator to lift the handle part with one hand while simultaneously touching the operating part to perform locking or unlocking actions.

2. A folding rowing machine according to claim 1 wherein: Both the handle and the operating part are located on the upper side of the folding rowing machine when in use.

3. A folding rowing machine according to claim 2 wherein: Both the handle and the operating part are located on the upper side of the main frame.

4. A folding rowing machine according to claim 3 wherein: The locking and unlocking mechanism further includes an execution component, which includes a connecting frame, a limiting rod, and an elastic element. The connecting frame is hinged to the main frame via a hinge shaft, and the limiting rod is disposed on the connecting frame. The first hinge end of the slide rail frame is provided with an unfolding stop groove and a folding stop groove at intervals. The elastic element acts on the connecting frame and generates a restoring force that drives the limiting rod to swing around the hinge shaft in a first direction, so that the limiting rod can be engaged in the unfolding stop groove or the folding stop groove. The operating element can drive the limiting rod to swing around the hinge shaft in a second direction, so that the limiting rod can disengage from the unfolding stop groove or the folding stop groove.

5. A folding rowing machine according to claim 4 wherein: A connecting plate is fixedly provided at the first hinge end, and the unfolding stop groove and the folding stop groove are arranged at intervals along the edge of the connecting plate.

6. The folding rowing machine of claim 4, wherein: The main frame is hollow inside, and the execution component is arranged inside the main frame; the operating component includes an operating lever, which has a first end and a second end. The first end is located inside the main frame and abuts against the connecting frame, and the second end is located outside the main frame and serves as the operating part; force is applied to the connecting frame by pressing the operating part.

7. A folding rowing machine according to claim 6 wherein: A fixing sleeve is installed on the outer wall of the main frame, and a limiting cap is fitted on the operating part. The limiting cap is slidably connected to the fixing sleeve to limit the movement of the operating rod away from the connecting frame.

8. A folding rowing machine according to claim 7, wherein: The main frame has symmetrical arc-shaped holes on its two opposite side walls. The center of the arc-shaped hole is located on the axis of the hinge shaft. The limiting rod passes through the arc-shaped hole to limit the swing stroke of the limiting rod and limit the movement stroke of the operating rod toward the connecting frame.

9. The folding rowing machine of claim 4, wherein: The connecting frame includes a second hinge end and a free end. The second hinge end of the connecting frame is hinged to the main frame through a hinge shaft to form a swing rod structure. The limiting rod is disposed at the free end of the connecting frame.

10. The folding rowing machine of claim 4, wherein: The limiting rod and the unfolding stop groove are configured such that: when the slide rail frame is in the unfolded state, the groove opening direction of the unfolding stop groove deviates from the movement trajectory of the limiting rod swinging around the hinge axis, thereby interfering with the movement of the limiting rod toward the groove opening direction of the unfolding stop groove; the first hinge end and the main frame rotate relative to each other through the lifting handle, so that the groove opening direction of the unfolding stop groove is approximately the same as the movement trajectory of the limiting rod swinging around the hinge axis, thereby eliminating the interference of the limiting rod moving toward the groove opening direction of the unfolding stop groove; when the slide rail frame is in the folded state, the groove opening of the folded stop groove is approximately the same as the movement trajectory of the limiting rod swinging around the hinge axis.

11. A folding rowing machine according to claim 10, wherein: A seat cushion is slidably mounted on the slide rail frame. The operating part is configured such that when the slide rail is in a folded state, the operating part is located below the seat cushion in the vertical direction, and the vertical projection of the operating part is located within the projection plane of the seat cushion.

12. The folding rowing machine of claim 10, wherein: The unfolding stop groove includes a first groove wall, which is configured such that when the handle is pulled upward by an external force, the first hinge end rotates relative to the main frame, so that the first groove wall applies force to the limiting rod, thereby causing the limiting rod to swing around the hinge axis to the opening of the unfolding stop groove.

13. The folding rowing machine of claim 1, wherein: The positional interval is smaller than the maximum span between the thumb and index finger of a human hand; And / or, the main frame is provided with a first support seat and a second support seat at intervals, and the slide rail frame is provided with a third support seat; the second support seat is hinged to the first hinge end; And / or, the slide rail frame is provided with a handrail on its lower side when it is in the unfolded state.
