[0024] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0025] like Figures 1-6 As shown, this embodiment provides a height adjustment component for a press trainer, including a base 10, a movable plate 20, and a support block 30.

[0026] The base 10 is installed at an angle on the frame of the press trainer and fixed to the frame by common methods such as bolts or welding, as shown in the figure. The figure illustrates the application of the height adjustment component in a double-rail inclined seated chest press trainer. The base has an L-shaped structure consisting of a horizontal seat 11 and a vertical seat 12. The horizontal seat 11 serves two purposes: first, it is used to fix the base to the frame; second, it provides a support surface and adjustment space for the second end of the movable plate 20. The vertical seat 12 provides different positioning heights relative to the vertical direction. The vertical seat 12 of the base 10 has four sets of slots 101 arranged vertically and horizontally, and a transition groove 102 connecting the same side of each slot 101. The vertical seat 12 is composed of two side plates arranged at intervals. Each set of slots 101 consists of two through slots that are directly opposite each other on the two side plates. The space between the two side plates is used to move the movable plate 20, and the transition groove 102 provides a channel for the movable plate 20 to switch between different slots 101.

[0027] In this embodiment, the first end of the movable plate 20 is switched and positioned within one set of slots 101 via the transition groove 102. The movable plate 20 changes its tilt angle relative to the cross seat 11 by being positioned within slots 101 at different heights. The tilt angle difference of the movable plate 20 is 10° (the tilt angle difference is set between 8° and 15° depending on the number of slots 101 and height adjustment requirements). The support block 30 is fixedly installed on the top of the movable plate 20. The support height of the support block 30 changes with the tilt angle of the movable plate 20, and support blocks 30 at different support heights are all located on the moving arm movement path of the lifting trainer. The second end of the movable plate 20 abuts against the cross seat 11.

[0028] The first end of the movable plate 20 is provided with a locking post 21 at the position corresponding to the slot 101. The opening height of the slot 101, which connects to the transition groove 102, is higher than the locking height of the slot 101 and the locking post 21. The locking post 21 engages with the slot 101 and slides with the transition groove 102, allowing the movable plate 20 to move within the transition groove 102 and, after adjustment, to remain fixed to the base 10. In this embodiment, the height of the support block 30 can be adjusted simply by pulling the movable plate 20 and switching to different slot 101 positions. This is simple, quick, and requires no standing up; the trainee can adjust it themselves. The first end of the movable plate 20 is connected to an operating rod 23, which is used to adjust the movable plate 20.

[0029] The horizontal base 11 has transverse grooves 103 at corresponding positions on both sides. The second end of the movable plate 20 has a sliding block 22 at a position corresponding to the groove 103. The sliding block 22 slidably engages with the groove 103. Preferably, the sliding block 22 has a circular cross-sectional shape, allowing the second end of the movable plate 20 to rotate freely within the groove 103. Of course, the sliding block 22 can have other cross-sectional shapes to meet the angle adjustment requirements of the movable plate 20.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
