Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to an adjustable dumbbell support frame for placing adjustable dumbbells. Background Art

[0002] Dumbbells can be classified into fixed-weight dumbbells and adjustable-weight dumbbells according to their structures. Fixed-weight dumbbells need to be equipped with multiple dumbbells of different weights and matching dumbbell racks consistent with the weights of different dumbbells, which have the problems of large volume, low resource utilization rate, and high purchase cost. Adjustable-weight dumbbells can select different weights by adjusting the dumbbell handle in cooperation with a dumbbell base. A set of adjustable-weight dumbbells can replace multiple fixed dumbbells of different weights, having the advantages of small volume, high resource utilization rate, and low purchase cost. However, the following problems exist in the use process: First, when adjusting the weight of the adjustable-weight dumbbell, it must be used in cooperation with a dumbbell base. Since the dumbbell base is placed on the ground, when adjusting the weight and lifting the dumbbell for training, it is necessary to bend down and lower the head, which will not only cause damage to the waist but also bring inconvenience to the trainer. Second, in order to facilitate the use of adjustable-weight dumbbells, Chinese Patent Publication No. CN220276210U discloses a dumbbell rack. The dumbbell rack includes a base, a support rod, a support plate arranged on the support rod, and a fence around the support plate. When in use, the adjustable-weight dumbbell base is placed on the support plate and can be used. Its disadvantage is that the dumbbell base cannot be stably connected to the support plate; in order to be used in cooperation with adjustable-weight dumbbells of different structures, the support plate is often designed to be larger, and the dumbbell base will move back and forth and left and right during use, which is not conducive to weight adjustment. If the separation between the dumbbell and the dumbbell base is unreliable, the dumbbell base will be taken out from the support plate and hit the foot, posing a serious safety hazard. In view of the above problems, many manufacturers and people of insight have carried out development and research, but so far, no satisfactory products have been introduced. Summary of the Invention

[0003] In order to overcome the above-mentioned defects existing in the prior art, the purpose of the utility model is to provide an adjustable dumbbell support frame with simple structure, convenient operation, good stability and versatility, and safe use.

[0004] The technical solution adopted by the utility model to solve the above technical problems includes a support base and a support frame. There are two cross bars on the support frame, and dumbbell base support plates for placing dumbbell bases are correspondingly fixed on the cross bars. A dumbbell base backing adjustment device is arranged on the dumbbell base support plate. The dumbbell base backing adjustment device includes an adjustment slot arranged on the dumbbell base support plate, a backing adjustment block that can move back and forth and cooperate with the dumbbell base, an adjustment knob, and a rotation prevention piece arranged at the bottom of the dumbbell base support plate. The screw rod of the adjustment knob passes through the backing adjustment block and the adjustment slot and is connected to the screw hole of the rotation prevention piece; when the adjustment knob is tightened, the backing adjustment block is fixed on the dumbbell base support plate, and when the adjustment knob is loosened, the backing adjustment block can move back and forth relative to the dumbbell base support plate and closely adhere to the dumbbell base.

[0005] A further solution of the present utility model is that a belt buckle for fixing the dumbbell seat is provided on the dumbbell seat support plate, and the left and right sides of the belt buckle are correspondingly fixed on the left and right sides of the dumbbell seat support plate.

[0006] A further solution of the present utility model is that adjusting holes for adjusting the belt length are correspondingly provided on the left and right sides of the belt buckle.

[0007] A further solution of the present utility model is that a U-shaped groove frame matching with the cross bar is provided at the bottom of the dumbbell seat support plate. The U-shaped groove frame is buckled on the cross bar and fastened by bolts, and a reinforcing plate is provided between the U-shaped groove frame and the bottom surface of the dumbbell seat support plate.

[0008] After adopting the above structure, compared with the prior art, there are the following advantages and effects: First, the dumbbell seat can be stably connected to the dumbbell seat support plate through the belt buckle, and the backing adjustment block can be closely attached to the dumbbell seat through the dumbbell seat backing adjustment device, so as to ensure that the dumbbell seat will not move forward, backward, left or right, and the dumbbell weight adjustment is stable and reliable. Second, through the belt buckle and the dumbbell seat backing adjustment device, it can be ensured that adjustable dumbbells with different manufacturers and different specifications can be used in a matching manner, solving the problem of poor universality of existing dumbbell supports.

Detailed Embodiments

[0015] Figures 1 to 5As shown in the figure, this is the physical implementation of the adjustable dumbbell support of the present utility model. It includes a support base 1 and a support frame 2. There are two crossbars 6 on the support frame 2. Dumbbell seat support plates 4 for placing dumbbell seats 14 are correspondingly fixed on the crossbars 6. A dumbbell seat backrest adjustment device 3 is provided on the dumbbell seat support plate 4. The dumbbell seat backrest adjustment device 3 includes an adjustment slot 8 provided on the dumbbell seat support plate 4, a backrest adjustment block 10 that can move back and forth and cooperate with the dumbbell seat 14, an adjustment knob 11, and an anti-rotation piece 7 provided at the bottom of the dumbbell seat support plate 4. When the adjustment knob 11 rotates, the screw rod will not drive the anti-rotation piece 7 to rotate, mainly to solve the problem that the backrest adjustment block 10 cannot be fixed firmly. The screw rod of the adjustment knob 11 passes through the backrest adjustment block 10 and the adjustment slot 8 and is connected to the screw hole of the anti-rotation piece 7. When the adjustment knob 11 is tightened, the backrest adjustment block 10 is fixed on the dumbbell seat support plate 4. When the adjustment knob 11 is loosened, the backrest adjustment block 10 can move back and forth relative to the dumbbell seat support plate 4 and closely adhere to the dumbbell seat 14.

[0016] In order to ensure that the dumbbell seat 14 is convenient to disassemble and connect reliably with the dumbbell seat support plate 4, a belt buckle 5 for fixing the dumbbell seat 14 is provided on the dumbbell seat support plate 4. The left and right sides of the belt buckle 5 are correspondingly fixed on the left and right sides of the dumbbell seat support plate 4.

[0017] In order to cooperate with different weight-adjustable dumbbells, adjustment holes 9 for adjusting the belt length are correspondingly provided on the left and right sides of the belt buckle 5. The length of the belt buckle 5 is adjusted through the adjustment holes 9.

[0018] In order to ensure that the dumbbell seat support plate 4 is convenient to install and connect firmly with the crossbar 6, a U-shaped groove frame 12 that cooperates with the crossbar 6 is provided at the bottom of the dumbbell seat support plate 4. The U-shaped groove frame 12 is buckled on the crossbar 6 and fastened by bolts. A reinforcing plate 13 is provided between the U-shaped groove frame 12 and the bottom surface of the dumbbell seat support plate 4.

[0019] The above is only a specific embodiment of the present utility model, and does not impose any formal restrictions on the present utility model. Without departing from the technical solution of the present utility model, simple modifications, equivalent changes or decorations made all fall within the protection scope of the present utility model.
