DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] like Figures 1 to 8 As shown, a dragon boat rowing exercise device of the present invention includes a dragon-shaped exercise frame 1, which is set on the ground. A pair of paddling exercise assemblies are symmetrically arranged on the left and right sides of the exercise frame 1. The paddling exercise assembly includes a seat 2 for a person to sit on, a crank rocker mechanism 3 arranged above the seat 2, a rocker 4 of the crank rocker mechanism 3 connected to the upper front end of the exercise frame 1, a crank 5 of the crank rocker mechanism 3 arranged at the rear end of the exercise frame 1, and a connecting rod 6 of the crank rocker mechanism 3 serving as a paddle. During use, the person sitting on the seat 2, holding the lower end of the connecting rod 6 of the crank rocker mechanism 3 with the inside hand and the upper end of the connecting rod 6 of the crank rocker mechanism 3 with the outside hand, performs a paddling action through the connecting rod 6 of the crank rocker mechanism 3. Each rotation of the crank 5 completes a complete paddling cycle, thereby achieving the paddling exercise of the dragon boat rowing sport. The device is easy to use and can be conveniently performed on land.

[0020] It should be noted that during the dragon boat rowing exercise, a complete rowing cycle consists of four parts: entering the water, pulling the oars, exiting the water and moving the oars in the air. By using a crank-rocker mechanism as the equipment for the rowing action, and utilizing the connecting rod of the crank-rocker mechanism to drive the crank and rocker movement, each rotation of the crank completes a complete rowing cycle, thereby effectively simulating the dragon boat rowing action.

[0021] In this embodiment, the crank-rocker mechanism 2 of each rowing exercise component includes a crank 5, a connecting rod 6 and a rocker 4. The connecting rod 6 is inclined with a high front end and a low rear end. The front end of the connecting rod 6 is hinged to the lower end of the rocker 4, and the upper end of the rocker 4 is rotatably connected to the upper front end of the exercise frame 1; the crank 5 is disc-shaped and rotatably mounted on the rear end side of the exercise frame 1 (that is, a pair of rowing exercise components are mounted on the left and right sides of the rear end of the exercise frame), the axis of the crank 5 extends in the left and right directions, and the inner side of the rear end of the connecting rod 6 is connected to a horizontally arranged connecting rod 7, and the connecting rod 7 is rotatably connected to the outer end face of the crank 5, and the rocker swings and the crank rotates through the connecting rod.

[0022] In this embodiment, the exercise frame 1 includes a dragon head 101, a dragon body 103 and a dragon tail 102 arranged in sequence from front to back, and the exercise frame is fixed with support rods 8 on the left and right end surfaces of the dragon head 101; a connecting through hole is opened at the upper end of the rocker 4, and the support rod 8 passes through the connecting through hole, and the rocker 4 is rotatably connected to the support rod 8 through the connecting through hole; the crank 5 is rotatably installed on the side of the dragon tail 102 of the exercise frame 1.

[0023] In this embodiment, the dragon body 103 of the exercise frame is V-shaped, and a pair of dragon boat drums 9 distributed on the left and right are provided between the front and rear sides of the dragon body 103 of the exercise frame. The dragon boat drum 9 has a planar structure, and the rear side of the dragon body 103 of the exercise frame 1 is provided with a pair of long grooves 10 distributed on the left and right. The position of the pair of long grooves 10 corresponds to the position of the pair of dragon boat drums 9. The long grooves 10 are inclined with a low front end and a high rear end. A drum rod 11 is provided in each long groove 10. The drum rod 11 is inclined with a low front end and a high rear end. The rear end of the drum rod 11 is The end of the crank 5 extends into the tail 102 of the exercise frame and is hinged to the tail 102 of the exercise frame 1, allowing the drumstick to swing up and down around the hinge. The front end of the drumstick 11 is spherical and rests against the surface of the dragon boat drum 9. The inner end surface of the crank 5 is fixed with a horizontally arranged driving rod 12, which is coaxial with the connecting rod 7 and rotates synchronously with the crank 5. When the driving rod 12 rotates with the crank 5, it pushes the drumstick 11 upward. After the driving rod 12 rotates and separates from the drumstick 11, the drumstick 11 swings downward and strikes the dragon boat drum 9, achieving the drumming. The driving rod is used to push the drumstick, and the drum is struck once after a complete rowing cycle (the crank drives the driving rod to rotate one circle). In traditional dragon boat racing, the frequency of the drum sound is often closely related to the rowing frequency and the speed of the boat. The user strikes the drum once every time he paddles, which reflects the speed of the rowing.

[0024] It should be noted that this exercise device features two paddling exercise components, allowing two people to perform paddling exercises simultaneously. Each person's paddling motion creates a separate drumming action. In dragon boat racing, coordination with team members is essential. When the drumming on both sides of the device is consistent, it reflects the consistent movement frequency of the "rowers" on both sides. This interactive sound system increases the fun of using the product and can also attract passers-by to experience and use it.

[0025] In the present embodiment, the drumming rod 11 can be a telescopic rod, comprising three rod bodies arranged in sequence, and adjacent rod bodies can be locked by set screws. When it is not necessary to beat the drum, the drumming rod is retracted so that the drumming rod does not beat the dragon boat drum, thereby avoiding the drum sound disturbing people.

[0026] In this embodiment, in order to facilitate the outer hand to grasp, a horizontally arranged hand grip 13 is fixed to the outer side of the upper end of the connecting rod 6. Further, the hand grip is located below the hinge of the rocker and the connecting rod.

[0027] It should be noted that dragon boat rowing itself places significant strain on the rower's waist and arm strength, and the movement itself is inherently difficult and dangerous. When paddling, the upper hand is often positioned above the head, and the upper torso is nearly parallel to the ground when pulling. This type of movement is unsuitable for fitness novices and elderly users, and can easily lead to strains and bumps. Therefore, the design integration should reduce the tilt of the crank arm. Specifically, the height of the hinge between the arm and the connecting rod and the upper grip (i.e., the hand grip) should be lowered to minimize the range of motion, achieving fitness without injury. Furthermore, if the crank arm is tilted too much to achieve a realistic movement, the upper grip will be close to the user's head, making it prone to bumps and bumps when the user stands up.

[0028] In this embodiment, an adjustment slot 14 is provided on the outer side of the upper end of the connecting rod 6 (i.e., the side facing away from the exercise frame). This slot 14 extends along the length of the connecting rod 3. The inner end of the grip bar 13 extends into and slidably engages with the adjustment slot 14. A plurality of locking bolts 15 are evenly spaced side by side at the top of the adjustment slot 14. These locking bolts 15 are used to lock the grip bar 13 after it slides along the adjustment slot 14. The grip bar is designed to slide along the adjustment slot to accommodate different forearm lengths. Furthermore, since forearm length ≈ height × 0.16, height can be roughly inferred from forearm length. In this case, a height scale can be provided on the outer side of the upper end of the connecting rod, above the adjustment slot. Each locking bolt corresponds to a height scale value, providing a reference for the user and reducing the trial-and-error process during use.

[0029] In this embodiment, the lower rear end of the exercise frame 1 (that is, the lower part of the dragon tail of the exercise frame) is provided with a horizontal U-shaped slot 16, the rear end, left end and right end of the slot are all open, and a pair of upper and lower stacked horizontal swing rods 17 are hinged between the top and bottom of the slot 16 through a vertical hinge shaft. The horizontal swing rod can swing left and right around the hinge, and a pair of horizontal swing rods 17 extend from the left and right sides of the slot 16 respectively; the seat 2 is a flat plate structure and is arranged horizontally, and the bottom of the seat 2 is at A support leg 18 is fixed to the end away from the exercise frame for support on the ground. An inverted T-bar 19 is fixed to the bottom of the seat 2 at the end closest to the exercise frame 1. The rear end of the inverted T-bar 19 is fixedly connected to a horizontal swing rod 17 located on the same side, connecting the seat 2 and the horizontal swing rod 17 on the same side as a whole. The horizontal swing rod 17 drives the seat 2 to rotate synchronously. The seats 2 on the left and right sides of the exercise frame 1 can be swung backward toward each other and close together via a pair of horizontal swing rods 17. When the seats on the left and right sides of the exercise frame are close together, it is a single-person mode. The user's role changes from "rower" to "drummer". The "drummer" sits on the seat, holds the connecting rod with both hands, and rotates the crank of the crank rocker mechanism through the connecting rod. The rotation of the crank drives the drum stick to strike the dragon boat drum, achieving drumming.

[0030] In this embodiment, an I-shaped base rod 20 is fixed to the lower end of the exercise frame 1. The base rod 20 is arranged in the front and rear directions, and the entire exercise frame is firmly supported by the base rod 20.

[0031] In this embodiment, a rear support foot block 21 is fixed to the front lower end of the inverted T-shaped rod 19 for the back foot to rest against. A pair of symmetrically distributed front support foot blocks 22 are fixed to the front end of the base rod 20. The front support foot blocks 22 facilitate the front foot to rest against each other. By providing the front and rear support foot blocks, when paddling, the user's back foot rests against the rear support foot block and the front foot rests against the front support foot block, and the user's sitting posture at this time is similar to that of a user sitting on a dragon boat.

[0032] In this embodiment, a pair of left-right symmetrically distributed support pads 23 are fixed to the rear end of the base rod 20 . The support pads 23 are cylindrical and sleeved on the outer side of the rear end of the base rod 20 .

[0033] In this embodiment, in the initial state, a pair of rowing exercise components are distributed on the left and right sides of the exercise frame. During exercise, two rowers sit on the seats 2 on the left and right sides of the exercise frame (this is a double-person mode), with their front feet resting on the front resting foot blocks 22 and their back feet resting on the back resting foot blocks 21. The inner hands hold the lower end of the connecting rod 6 of the crank rocker mechanism 3, and the inner hands hold the hand grip 13 at the upper end of the connecting rod 6. The rowers perform rowing movements through the connecting rod 6 of the crank rocker mechanism. Each time the crank 5 rotates one circle, a complete rowing cycle is achieved. During this process, the shifting rod 12 pushes the drum-beating rod 11 upward as the crank 5 rotates, and after the shifting rod 12 rotates to separate from the drum-beating rod 11, the drum-beating rod 11 swings downward and beats the dragon boat drum 9 to achieve drumming, that is, the drum is beaten once after a complete rowing cycle (the crank drives the shifting rod to rotate one circle) is completed. When the seats on the left and right sides of the exercise frame are close together, it is a single-person mode. At this time, the user's identity changes from a "rower" to a "drummer". The "drummer" sits on the seat, holds the connecting rod with both hands, and rotates the crank 5 of the crank rocker mechanism through the connecting rod 7. When the crank 5 rotates, it drives the drumming rod 11 to beat the dragon boat drum 9, thereby achieving drumming.

[0034] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integrated molding using a casting process) (except where it is obviously impossible to use an integrated molding process).

[0035] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the present invention to express positional relationships or shapes include states or shapes that are approximate, similar, or close thereto.

[0036] Any component provided by the present invention may be assembled from multiple separate components, or may be a separate component manufactured by an integral molding process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present invention.
