Description

Technical Field

[0001] This utility model relates to the field of dumbbell bench technology, and in particular to a dumbbell bench. Background Technology

[0002] A dumbbell bench is a fitness aid. It's commonly used to assist dumbbells in performing essential exercises such as incline dumbbell bench presses, decline dumbbell bench presses, and flat dumbbell flyes. Using dumbbells improves joint and muscle control in various parts of the body, works the smaller muscle groups surrounding the target muscle group, and effectively stimulates the muscle tissue at the junctions between different muscle groups. This leads to tighter connections between muscle groups, resulting in more coordinated and well-developed muscles. These targeted exercises cannot be performed without the assistance of a dumbbell bench, hence its name.

[0003] Existing technology, such as CN219896926U, discloses a multi-functional dumbbell bench, including a support base, a seat cushion assembly on the upper front side of the support base, a backrest assembly on the upper rear side of the support base, and a foot hook assembly on the support base in front of the seat cushion assembly. The seat cushion assembly includes a seat cushion frame, and an adjustment frame that can slide and be fixed along the seat cushion frame is provided on the seat cushion frame. The seat cushion is fixed on the adjustment frame, and the seat cushion can be fixed away from or closer to the backrest assembly through the adjustment frame. This multi-functional dumbbell bench has the advantages of comfortable use and convenient adjustment.

[0004] Regarding the above and existing related technologies, the inventor believes that the following defects often exist: When adjusting the dumbbell bench, the limiting device is fixed to the adjustment holes at different positions through multiple preset adjustment holes to adjust the angle of the seat on the dumbbell bench. Since there is a gap between the adjustment holes, the adjustable angle of the seat on the dumbbell bench is limited to a few preset commonly used angles with fixed settings. However, since people using dumbbell benches have different heights, the preset angles cannot fully adapt to different users.

[0005] Therefore, we propose a dumbbell bench. Utility Model Content

[0006] Given the gap between the existing adjustment holes, the adjustable angles of the dumbbell bench seat are limited to a few commonly used preset angles. However, since the height of users of the dumbbell bench varies, the preset angles cannot adequately accommodate different users. Therefore, this utility model was proposed.

[0007] Therefore, the purpose of this utility model is to provide a dumbbell bench, the purpose of which is that the angle of the seat cushion on the dumbbell bench can be adjusted arbitrarily to fully adapt to different users.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0027] Reference Figure 1-3 This is the first embodiment of the present utility model, which provides a dumbbell bench. This dumbbell bench includes a crossbeam plate 1, a side frame A2 welded to one side of the crossbeam plate 1, a side frame B3 welded to the other side of the crossbeam plate 1, a rotating mounting seat 6 welded to the top of the crossbeam plate 1 and the side near the side frame B3, a rotating shaft 7 rotatably mounted on both sides inside the rotating mounting seat 6 via bearings, a rotating bar A8 rotatably mounted on the rotating mounting seat 6 via the rotating shaft 7 on the side near the side frame A2, a soft pad A9 fixedly mounted on the top of the rotating bar A8, and a rotating bar B10 rotatably mounted on the rotating mounting seat 6 via the rotating shaft 7 on the side near the side frame B3, a soft pad B11 fixedly mounted on the top of the rotating bar B10;

[0028] A drive source B15 for driving the soft pad B11 to rotate is installed between side frame B3 and side frame A2, and the drive end of drive source B15 is connected to the bottom of rotating bar B10. A drive source A14 for driving the soft pad A9 to rotate is installed between side frame B3 and the bottom of crossbeam plate 1, and the drive end of drive source A14 is connected to the bottom of rotating bar A8. A hook leg assembly 16 is installed on side frame A2.

[0029] Both side frame A2 and side frame B3 have flat strip pads 4 welded to their bottom ends. Rubber pads 5 are glued to the bottom of the flat strip pads 4. The rubber pads 5 increase the friction coefficient with the ground to prevent slipping, but also prevent scratches on the ground.

[0030] The drive source A14 and drive source B15 have the same structure. Drive source B15 includes two vertical frame plates 153. The vertical frame plate 153 of drive source B15 is welded to the bottom of the side frame B3. The vertical frame plate 153 of drive source A14 is welded to the bottom of the crossbeam plate 1. A mounting shaft 154 is rotatably mounted between the opposite surfaces of the two vertical frame plates 153 via bearings. A gear 155 is sleeved on the outer wall of the mounting shaft 154. An arc-shaped rack 157 is meshed on the gear 155, and one end of the arc-shaped rack 157 is welded to the bottom of the rotating bar B10. One end of the arc-shaped rack 157 on A14 is welded to the bottom of the rotating bar A8. The top of the side frame B3 and the crossbeam plate 1 are both provided with a through-hole 12 for the arc-shaped rack 157 to pass through. The adjustment of the soft pads B11 and A9 is controlled by the meshing transmission of the gear 155 and the arc-shaped rack 157. When the angle of the soft pads A9 and B11 is adjusted, the start and stop can be controlled at any time. There is no gear setting. The soft pads A9 and B11 can be adjusted to any angle position to fit different users and can fit them completely.

[0031] The drive source B15 also includes a motor frame 151, which houses a servo motor 152 for driving the mounting shaft 154, and the drive end of the servo motor 152 is connected to one end of the mounting shaft 154.

[0032] The drive source B15 also includes an arc-shaped slide 156, which is welded between the side frame A2 and the side frame B3. The arc-shaped slide 156 on the drive source A14 is welded between the side frame B3 and the crossbeam plate 1. The inner wall of the arc-shaped slide 156 is provided with a groove 158. The arc-shaped rack 157 has a guide strip welded on its arc-shaped surface that slides inside the groove 158. The arc-shaped rack 157 slides inside the groove 158 on the arc-shaped slide 156 through the guide strip, which provides support and limits the arc-shaped rack 157 and ensures the stability of the arc-shaped rack 157 in the working state.

[0033] A chassis 13 is installed at the bottom of the side frame B3, between the drive source B15 and the drive source A14, and a battery is installed inside the chassis 13.

[0034] During use, the principle of adjusting the angle of the soft pad A9 by the drive source A14 is the same as that of adjusting the angle of the soft pad B11 by the drive source B15. Taking the adjustment of the soft pad B11 by the drive source B15 as an example, the process is as follows:

[0035] The mounting shaft 154 is driven to rotate by the servo motor 152, which in turn drives the gear 155 to rotate. Under the meshing transmission action of the gear 155 and the arc rack 157, the arc rack 157 will be driven to rotate and move.

[0036] When gear 155 rotates clockwise, it controls the arc-shaped rack 157 to rotate clockwise, lifting the soft pad B11 upwards. When gear 155 rotates counterclockwise, it controls the arc-shaped rack 157 to rotate counterclockwise, pulling the soft pad B11 downwards. By controlling the clockwise and counterclockwise rotation of gear 155, the arc-shaped rack 157 is controlled to rotate clockwise and counterclockwise, driving the soft pad B11 to rotate and move, thereby adjusting the angle of the soft pad B11. Example

[0037] Reference Figure 1-3 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0038] The leg hook assembly 16 includes a bracket 163 that slides on the outer inclined surface of the side frame A2, and leg hook foam 164 is installed on both the front and back of the bracket 163.

[0039] The leg hook assembly 16 also includes a linear motor 161 installed on the inclined surface inside the side frame A2, and the movable end of the linear motor 161 is connected to the bracket 163. The inclined end of the side frame A2 is provided with a connecting channel 162 through which the movable end of the linear motor 161 passes. The distance between the leg hook assembly 16 and the crossbeam plate 1 can be adjusted according to different users to make it in the most suitable position, suitable for users with different leg lengths, and improve the comfort of use.

[0040] During use, the linear motor 161 drives the bracket 163 to move on the inclined surface of the side frame A2, which in turn drives the hook leg foam 164 to move, thereby adjusting and controlling the distance between the hook leg foam 164 and the crossbeam plate 1.

[0041] The remaining structure is the same as that in Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
