Description

Technical Field

[0001] This utility model belongs to the field of rowing machine technology, specifically relating to a new type of multi-functional rowing machine. Background Technology

[0002] In the field of fitness equipment, rowing machines, as devices that simulate rowing, are highly favored by fitness enthusiasts because they can effectively improve cardiovascular function and physical strength.

[0003] Existing rowing machines are usually based on the principle of mechanical transmission. They use the user to push the handles to drive the resistance device to generate motion resistance, thereby simulating the exercise effect of rowing. The user operates the handles and pedals, and through the transmission components such as ropes and linkages, in conjunction with the resistance system, the upper and lower limbs move in a coordinated manner to achieve muscle training, mainly in the arms and legs. However, the movement pattern is relatively fixed.

[0004] Currently, rowing machines mostly focus on a single rowing motion, which can only perform routine exercises on specific muscle groups. They cannot flexibly switch training modes, making it difficult to meet users' diverse training needs for different muscle groups throughout the body, resulting in low flexibility of use. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a novel multi-functional rowing machine, comprising a body, a first handle, a support block, a foot extender, and a fixing plate. The inner surface of the support block has a slot, and a connecting rod is slidably connected to the inner surface of the slot. A second handle is fixed to the side surface of the connecting rod. The support block has a first threaded hole inside, and the connecting rod has a second threaded hole inside. A screw is threaded to the inner surface of the first threaded hole. A support frame is fixedly connected to the side surface of the fixing plate. A seat cushion is provided inside the body, and a third handle is fixedly connected to the side surface of the seat cushion.

[0006] Through the above technical solution, the structure achieves a modular design for chest press function through the connecting rod and the second handle, and can perform lower limb training through the third handle and the leg extender. Compared with the traditional rowing machine, this structure adds chest press and leg press, expanding the specialized training functions for the upper and lower body. It can complete the training of multiple parts such as chest, shoulders, arms and legs on the same equipment, and achieve the full-body exercise effect of one machine. The rowing machine can flexibly switch training modes to meet the diverse training needs of users for different muscle groups of the whole body. The rowing machine is highly flexible in use.

[0007] The present invention is further configured such that the inner surface of the second threaded hole is threadedly connected to the screw, and a nut is threadedly connected to the side surface of the screw.

[0008] Through the above technical solution, the second handle can be quickly installed and removed through the slot and screw. When the second handle is not in use, it can be placed on the back side, keeping the overall equipment simple and compact, improving its adaptability to small space scenarios, and eliminating the need for users to reserve space separately for storing additional components. The double locking of the screw and nut ensures the structural rigidity of the second handle during training, preventing the threads from loosening and causing safety hazards.

[0009] The present invention is further configured such that a sliding groove is provided inside the body, a slider is slidably connected to the inner surface of the sliding groove, and a movable seat is fixedly connected to the upper surface of the slider.

[0010] Through the above technical solution, in the mechanical structure system of the rowing machine, the slide and the slider are the basic components. The slide and the slider form a sliding pair, providing a movable track for the foot extension and the moving seat of the rowing machine.

[0011] The present invention is further configured such that the side surface of the movable seat is fixedly connected to the foot extender, and a fixing column is fixedly connected to the side surface of the movable seat.

[0012] Through the above technical solution, the sliding pair design of the slide groove and the slider enables the foot extender to be adjusted in position; the fixed column provides support for the support block.

[0013] The present invention is further provided with a pull rope inside the body, a resistance magnetic control wheel inside the body, and a locking handle inside the body.

[0014] Through the above technical solution, the combination of the resistance magnetic control wheel and the pull rope realizes the damping adjustment of the rowing motion. The locking handle is used to lock the magnetic control wheel, providing a static resistance source for the leg press. The same magnetic control wheel can switch between dynamic rowing mode and static leg press mode resistance through the locking handle.

[0015] The present invention is further configured such that a support column is provided inside the body, the side surface of the support column is fixedly connected to a fixing plate, a support rod is fixedly connected to the lower surface of the support column, and a mobile phone holder is fixedly connected to the side surface of the support block.
