Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a seat adjustment structure for a fitness device. Background Technology

[0002] Most existing fitness equipment is equipped with a seat to facilitate users' training of specific movements. Since users have different heights and different needs for seat position when training specific movements, there is a need for convenient seat adjustment. This has led to the development of adjustable fitness equipment seat structures. However, the existing adjustment method involves a sliding rail and a sliding seat, with the seat cushion mounted on the sliding seat. The seat moves along the sliding rail via rollers on the sliding seat, and the seat position is fixed by a pin. In actual use, because the seat cushion assembly is relatively large, three rollers are needed on the same side. However, this structure requires multiple rollers to be coaxial and coplanar, requiring high precision in the roller and sliding rail fit. This is difficult to guarantee in actual manufacturing processes. Customers have also reported problems with the smooth movement between the seat cushion rollers and the sliding rail, resulting in a poor user experience. Therefore, there is a need to design a seat adjustment mechanism that improves the smoothness of the seat cushion and sliding rail fit and enhances the user experience without increasing the precision of the roller and sliding rail fit. Utility Model Content

[0003] The purpose of this utility model is to provide a seat adjustment structure for a fitness device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A seat adjustment structure for a fitness device, characterized in that it includes a base frame, a slide rail, a slide seat, and a seat cushion. The base frame is mounted on the fitness device and placed on the ground, and has two upright columns of different heights. The slide rail is mounted on the two upright columns at a certain angle. The slide rail has grooves on both sides, and a locking seat is provided in the groove. The locking seat has multiple slots. The slide seat is mounted on the slide rail, and two fixed rollers, a movable roller, and a locking device are rotatably mounted on both sides. The slide seat has multiple rotating holes, locking holes, and movable holes on both sides. The fixed rollers and the locking device are rotatably mounted in the rotating holes by screws. The locking device has a locking rod that moves in the locking hole. The locking rod engages with the slot to restrict the movement of the slide seat. The movable roller is movably mounted in the movable hole by an eccentric plate. When the slide seat moves up and down on the slide rail, the movable roller performs an eccentric circular motion on the eccentric plate.

[0006] Furthermore, the card holder has fixed holes on both sides of the movable hole, the eccentric plate has two arc-shaped openings, a mounting hole, and a turntable movably disposed in the movable hole, the turntable has an opening at the eccentric position that aligns with the mounting hole, the movable roller is rotatably mounted on the movable hole and the opening on the inner side of the turntable by a screw, and the eccentric plate is mounted in the fixed hole by two screws passing through the arc-shaped openings respectively. When the eccentric plate moves along the arc-shaped openings, it drives the turntable to rotate in the movable hole, thereby driving the movable roller to perform eccentric circular motion.

[0007] Furthermore, the slide is provided with a handle, which is mounted on the lock. By pulling the handle, the lock is rotated, causing the locking rod to move in the lock hole, engaging with the slot for locking or disengaging from the slot for unlocking.

[0008] Furthermore, the seat cushion is mounted on the slide by screws.

[0009] Furthermore, the card holder is mounted on the inner wall of the slide groove by screws.

[0010] Furthermore, the locking component has an L-shaped structure, and a reset spring is installed on its screw for rotating and resetting and driving the locking rod into the slot.

[0011] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This utility model uses a locking mechanism to lock and unlock the slide block. After the slide block is unlocked, it slides along the groove of the slide rail. The two fixed rollers move synchronously, while the moving roller moves in an eccentric circular motion. This achieves a seat adjustment mechanism that improves the smoothness of the seat cushion and slide rail and enhances the user experience without increasing the precision of the roller and slide rail fit.

[0022] Example

[0023] Cooperate Figures 1 to 5 As shown, this utility model discloses a seat adjustment structure for a fitness equipment, characterized by: a base frame 1, a slide rail 2, a slide seat 3, and a seat cushion 4. The base frame 1 is mounted on the fitness equipment and placed on the ground, and has two upright columns 11 of different heights. The slide rail 2 is mounted on the two upright columns 11 at a certain angle and is fixed by having aligned screw holes and connecting with screws. The slide rail 2 has sliding grooves 21 on the left and right sides, and a retaining seat 22 is provided in the sliding grooves 21. The retaining seat 22 has multiple retaining slots. The slide seat 3 is mounted on the slide rail 2, and two seats are rotatably mounted on both sides. The slide block 3 has a fixed roller 31, a movable roller 32, and a locking element 33. Multiple rotating holes 301, locking holes 302, and movable holes 303 are provided on both sides of the slide block 3. The fixed roller 31 and the locking element 33 are rotatably mounted in the rotating holes 301 via screws. The locking element 33 has a locking rod 331 that moves in the locking hole 302. The locking rod 331 engages with a slot to restrict the movement of the slide block 3. The movable roller 32 is movably mounted in the movable hole 303 via an eccentric plate 34. When the slide block 3 moves up and down on the slide rail 2, the movable roller 32 performs an eccentric circular motion on the eccentric plate 34.

[0024] The card holder 22 has fixed holes 304 on both sides of the movable hole 303. The eccentric plate 34 has two arc-shaped openings 341, a mounting hole 342, and a turntable 343 movably disposed in the movable hole 303. The turntable 343 has an opening at an eccentric position that aligns with the mounting hole 342. The movable roller 32 is mounted on the movable hole 303 and the opening on the inner side of the turntable by a screw. The eccentric plate 34 is mounted in the fixed hole 304 by two screws passing through the arc-shaped openings 341 respectively. When the slide 3 moves, the eccentric plate 34 moves because the fixed hole 304 and the screws are fixed. When the eccentric plate 34 moves along the arc-shaped openings 341, it drives the turntable to rotate in the movable hole 303, which in turn drives the movable roller 32 to perform eccentric circular motion.

[0025] The slide block 3 is provided with a handle 35, which is installed on the lock 33. By pulling the lock 33 with the handle 35, the lock rod 331 is driven to move in the lock hole 302, and can be locked by engaging with the slot or unlocked by disengaging from the slot.

[0026] The seat cushion 4 is mounted on the slide block 3 by screws.

[0027] The card holder 22 is installed on the inner wall of the slide groove 21 by screws.

[0028] The locking member 33 has an L-shaped structure, and a reset spring is installed on its screw for rotating and resetting and driving the locking rod 331 into the slot.

[0029] In this embodiment, the sliding block 3 is locked and unlocked by the locking element 33. After the sliding block 3 is unlocked, it slides along the slide groove 21 of the slide rail 2. The two fixed rollers 31 keep moving synchronously, and the moving roller 32 performs eccentric circular motion. This realizes a seat adjustment mechanism that can improve the smoothness of the fit between the seat cushion 4 and the slide rail 2 and improve the user experience without improving the matching accuracy of the rollers and the slide rail 2.

[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
