Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a weightlifting bed with an adjustable seat. Background Technology

[0002] Weightlifting benches are an important part of fitness equipment, specifically designed for strength training. Their sturdy structure ensures safety during training, while the adjustable surface caters to the needs of different trainees. On a weightlifting bench, whether it's squats, deadlifts, or bench presses, trainees can unleash their maximum power, helping them build a strong physique and achieve their fitness goals.

[0003] However, the adjustment mechanisms of most weightlifting beds on the market require adjusting one backrest or seat at a time, which is a segmented adjustment. The backrest and seat cannot be adjusted in a coordinated manner, making the operation rather cumbersome. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology mentioned in the background section by proposing an adjustable seat weightlifting bed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-seat weightlifting bed includes a weightlifting bed body. A bottom tube is provided at the bottom of the weightlifting bed body. A sliding tube is slidably installed on the outer side of the bottom tube. A large connecting piece is fixedly connected to the upper end of the sliding tube. A seat tube and a backrest tube are provided on both sides of the upper end of the large connecting piece. A small connecting piece is fixedly connected to the side of the backrest tube closest to the seat tube. The outer side of the backrest tube is also connected to the outer side of the bottom tube via a connecting rod. A slot communicating with the inner cavity is provided at the bottom of the seat tube. One end of the small connecting piece movably passes through the slot and extends to the inner wall of the seat tube. A bearing is also connected to this end of the small connecting piece. A bearing groove is provided laterally on the inner wall of the seat tube, and the bearing is slidably disposed in the bearing groove.

[0007] Preferably, multiple sets of positioning holes are evenly arranged on the outer side of the bottom tube, and a pull pin is movably inserted into the outer side of the sliding tube, with the inner end of the pull pin inserted into the positioning hole.

[0008] Preferably, the contact surfaces of the sliding tube and the bottom tube are both designed with smooth surfaces, and the upper end of the bottom tube is also fixedly connected to a support block that is connected to the bottom of the backrest tube.

[0009] Preferably, the upper ends of the seat tube and the backrest tube are provided with soft padding.

[0010] Preferably, the seat tube, backrest tube, and large connecting piece are rotatably connected by a rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model is based on the existing structural design of a fitness weightlifting bed and improves upon it. In use, the seat tube and backrest tube can be rotatably connected by a large connecting piece at the upper end of the sliding tube on the bottom tube. The bearing at the inner end of the small connecting piece slides in the bearing groove. Since the small connecting piece is fixedly connected to the backrest tube, the angles of the seat tube and backrest tube can be adjusted simultaneously. After adjusting to the appropriate angle, the pull pin on the sliding tube can be engaged with the positioning hole on the outside of the bottom tube. The operation is very convenient.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 An adjustable weightlifting bed includes a weightlifting bed body 1. A bottom tube 2 is provided at the bottom of the weightlifting bed body 1. A sliding tube 3 is slidably installed on the outer side of the bottom tube 1. Multiple sets of positioning holes 101 are evenly arranged on the outer side of the bottom tube 2. A pull pin 102 is movably inserted into the outer side of the sliding tube 3, with the inner end of the pull pin 102 inserted into the positioning hole 101. A large connecting piece 4 is fixedly connected to the upper end of the sliding tube 3. A seat tube 5 and a backrest tube 6 are provided on both sides of the upper end of the large connecting piece 4. The seat tube 5, backrest tube 6, and the large connecting piece 4 are rotated via a pivot 8. The backrest tube 6 is fixedly connected to a small connecting piece 9 on the side near the seat tube 5. The backrest tube 6 is also connected to the outside of the bottom tube 2 via a connecting rod 13. The connecting rod 13 is rotatably connected to both the backrest tube 6 and the bottom tube 2. The bottom of the seat tube 5 is provided with a slot 10 that communicates with the inner cavity. One end of the small connecting piece 9 moves through the slot 10 and extends to the inner wall of the seat tube 5. The end of the small connecting piece 9 is also connected to a bearing 11. The inner wall of the seat tube 5 is provided with a bearing groove 12, and the bearing 11 is slidably disposed in the bearing groove 12.

[0022] Based on the above structure, when using this device, the pull pin 102 on the outside of the sliding tube 3 is removed in advance, and then the sliding tube 3 on the bottom tube 2 is slid. When the sliding tube 3 slides, it drives the large connecting piece 4 at the upper end to rotate and connect the seat tube 5 and the backrest tube 6 to move synchronously. The bearing 11 at the inner end of the small connecting piece 9 on the outside of the backrest tube 6 slides in the bearing groove 12 on the inner wall of the seat tube 5. Since the backrest tube 6 is rotatably connected to the bottom tube 2 through the connecting rod 13, the angles of the seat tube 5 and the backrest tube 6 can be adjusted simultaneously. After adjusting to a suitable angle, the pull pin 102 on the sliding tube 3 is engaged with the positioning hole 101 on the outside of the bottom tube 2 to fix the adjusted angle. The operation is very convenient.

[0023] The contact surfaces of the sliding tube 3 and the bottom tube 2 are both designed with smooth surfaces, which facilitates the smooth sliding of the sliding tube 3 on the outside of the bottom tube 2. The upper end of the bottom tube 2 is also fixedly connected to a support block 201 that is connected to the bottom of the backrest tube 6. In the default state, that is, when the backrest tube 6 is horizontal, the support block 201 can play an auxiliary support role for the backrest tube 6.

[0024] The seat tube 5 and backrest tube 6 are both equipped with soft pads 7 at their upper ends, making it convenient for trainees to sit or lean back, thus improving overall comfort.

[0025] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
