Description
Technical Field
[0001] This utility model relates to the field of exercise equipment, specifically a multifunctional dumbbell bench. Background Technology
[0002] Dumbbell benches are a common auxiliary equipment in fitness training, mainly used to support users in performing various free weight training movements, such as dumbbell bench presses, dumbbell flyes, and sit-ups. Their simple and practical design helps trainees complete exercises targeting the chest, shoulders, back, arms, and core muscles more safely and efficiently.
[0003] To accommodate the various training movements mentioned above, existing dumbbell benches typically feature adjustable backrests. For example, patent CN204106939U discloses a multi-functional dumbbell bench, including a front support and a rear support. A seat and backrest are connected to the rear support, while the front support has upper and lower footrests. A backrest support is located at the rear end of the backrest, with one end movably connected to the rear support. An adjustment frame that slides relative to the rear support is located on the rear support. A connecting rod that can rotate relative to the backrest support is located between the adjustment frame and the backrest support. The connecting rod can rotate relative to the adjustment frame. Multiple adjustment holes are located on the rear support, and locking pins that engage with the adjustment holes are located on the adjustment frame. Although the aforementioned patent discloses an adjustable backrest for the dumbbell bench, its functionality, limited to accommodating existing training movements, does not allow for the addition of other training functions.

The rear end of the backrest support rod 8 is provided with an insert plate 34 that can be inserted into a slot 211, and the bottom surface of the backrest support rod 8 is provided with a support part 35.
[0030] Reference Figures 1 to 5 Both the seat cushion support frame 4 and the backrest support frame 6 are adjustable. When the angle of the seat cushion support frame 4 needs adjustment, first pull out the pin 20 from its original socket 22, then rotate the seat cushion support frame 4 to a suitable angle, and finally reinsert the pin 20 into the new socket 22. When the angle of the backrest support frame 6 needs adjustment, first pull out the insert plate 34 at the rear end of the backrest support rod 8 from its original slot 211, then rotate the backrest support frame 6 and the backrest support rod 8 to a suitable angle, and finally insert the insert plate 34 at the rear end of the backrest support rod 8 into the new slot 211. When the backrest support frame 6 rotates to be parallel to the rear support rod 2, the bottom surface of the support part 35 abuts against the top surface of the rear support rod 2, thereby increasing the supporting force of the backrest support rod 8.
[0031] Reference Figure 1 The bottom of the rear support rod 2 is fixedly connected to a rear bottom rod 36, and the bottom of the rear bottom rod 36 is connected to two rear support feet 361 arranged on the left and right. The front support foot 171 and the two rear support feet 361 are existing anti-slip support feet, which can increase the friction between the support and the ground.
[0032] Reference Figure 1 , Figure 3 and Figure 5 The connecting rod 13 is connected to two connecting plates 37 arranged to the left and right. The lower rod 15 is fitted with a fourth bushing 38, which can be fixedly connected to the lower rod 15 by welding. A fourth screw 39 is fitted through the rear ends of the two connecting plates 37, passing through the fourth bushing 38. One end of the fourth screw 39 is threadedly connected to a fourth nut 40. After the two connecting plates 37 are locked together by the fourth screw 39 and the fourth nut 40, they are rotatably connected to the fourth bushing 38, allowing the user to flex their feet when doing sit-ups.
[0033] Reference Figure 4 and Figure 5 It should be noted that the first screw 24, the second screw 29, the third screw 32 and the fourth screw 39 are only threaded at the ends that mate with the first nut 25, the second nut 30, the third nut 33 and the fourth nut 40 respectively, and the rest of the parts that pass through the corresponding bushings are smooth straight rods.
[0034] Reference Figures 1 to 5 The design principle of this utility model is as follows: The angles of the seat cushion 5 and the backrest 7 are adjustable to meet the normal usage needs of the dumbbell bench, such as dumbbell bench press, dumbbell flyes, sit-ups, etc. Simultaneously, when the exerciser sits up or sits on the dumbbell bench, their hands can punch the punching ball 12. When punching the punching ball 12, the elastic bar 11 will undergo elastic deformation, and the exerciser can repeatedly punch the punching ball 12. When the dumbbell bench is not in use, the insert plate 34 is inserted into the last slot 211, so that the backrest 7 is in the lowest position. The elastic bar 11 is then removed, and the hand screw 18 is loosened. After the hand screw separates from the threaded hole on the lower rod 15, the lower rod 15 can rotate and fold relative to the U-shaped connector 16, further reducing the space occupied by the dumbbell bench.
[0035] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
