Description

Technical Field

[0001] This utility model relates to the field of fitness equipment testing technology, and more specifically, to a barbell strength testing device. Background Technology

[0002] The barbell bar is one of the key pieces of equipment used in weightlifting and fitness training. It is typically made of high-strength steel and has specific length, diameter, and weight specifications. The barbell bar is designed to withstand heavy loads and remain stable during training.

[0003] Patent CN217526232U discloses a barbell bar, including a bar body and a weight support mounted on the bar body. It also includes a sleeve and two gripping sleeves for the user to hold. The sleeve is fitted onto the outside of the bar body and is rotatably mounted relative to the bar body and the weight support. The outer side of the sleeve has threaded grooves, the rotation directions of which are opposite to those of the bar body's midpoint. The gripping sleeves are fitted onto the two threaded grooves with opposite rotation directions and move along the bar body through these grooves. This invention reduces the force required by the user to adjust the distance between their hands, ensuring training intensity while avoiding unnecessary muscle exertion; it also increases the contact area for rotational friction during use, improving the barbell's flexibility and overall lifespan.

[0004] While the device offers numerous benefits, it still presents the following challenges: Although the barbell bar can prevent unnecessary muscle exertion, as a crucial component of fitness equipment, its strength directly impacts user safety and training effectiveness. During exercise, the barbell bar must withstand significant loads; insufficient strength can lead to bending, breakage, and other accidents, causing injury to the user. Furthermore, the barbell bar's strength may vary depending on the location under stress, requiring multiple displacements for multi-directional testing. These multiple displacements necessitate more time and operation to complete the entire testing process, increasing not only the total testing time but also potentially affecting the smoothness of the testing procedure.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A barbell strength testing device includes a base plate 1, a connecting frame 2 fixedly connected to the top of the base plate 1, a connecting plate 3 on the outer side of the connecting frame 2, and a load-bearing block 10 on the outer surface of the connecting plate 3. The device also includes:

[0029] A movable component, located on the outer surface of the connecting frame 2, is used to drive the load-bearing block 10 to move laterally;

[0030] The detection component, located on the outer surface of the connecting plate 3, is used to drive the load-bearing block 10 to detect the barbell bar.

[0031] The placement component, located on the outer surface of the base plate 1, is used to support the barbell bar. The weight block 10 contacts the barbell bar and applies pressure, thereby enabling the strength testing of the barbell bar.

[0032] Furthermore, the moving component includes pulleys 4, belt 5, first motor 6, and locking block 14. The connecting frame 2 is arranged in a T-shape. Two pulleys 4 are rotatably connected to the outer surface of the connecting frame 2, and belt 5 is sleeved between the two pulleys 4. The first motor 6 is fixedly installed on the rear outer surface of the connecting frame 2. The output end of the first motor 6 is fixedly connected to the adjacent pulley 4. Locking block 14 is fixedly connected to the outer surface of belt 5 and is fixedly connected to connecting plate 3. The output end of the first motor 6 drives one pulley 4 to rotate. Through the transmission of belt 5, the other pulley 4 also rotates synchronously. Locking block 14 on the outer surface of belt 5 moves with belt 5.

[0033] Furthermore, two symmetrically distributed first guide rails 7 are fixedly connected to the front outer surface of the connecting frame 2. Two first sliders 15 are slidably connected to the outer surfaces of the two first guide rails 7. The four first sliders 15 are fixedly connected to the connecting plate 3. The connecting plate 3 and its detection components (including the load-bearing block 10) will move laterally along the first guide rails 7 and the first sliders 15 of the connecting frame 2 until the load-bearing block 10 is aligned with the position of the barbell bar that needs to be detected.

[0034] Furthermore, the detection components include a cylinder 8, a second guide rail 9, a pressure sensor 11, and a second slider 13. The cylinder 8 is fixedly installed on the top of the connecting plate 3, and the output end of the cylinder 8 is fixedly connected to the load block 10. Two symmetrically distributed second guide rails 9 are fixedly connected to the outer surface of the connecting plate 3, and the outer surfaces of the two second guide rails 9 are slidably connected to the second sliders 13. The two second sliders 13 are fixedly connected to the load block 10, and the pressure sensor 11 is fixedly installed on the outer surface of the load block 10. The output end of the cylinder 8 pushes the load block 10 downward until the load block 10 contacts the barbell and applies pressure. During this process, the pressure sensor 11 monitors and records the pressure value applied by the load block 10 to the barbell in real time. At the same time, the load block 10 is slidably connected to the second guide rail 9 and the second slider 13, ensuring its stability and accuracy when applying pressure. Based on the data recorded by the pressure sensor 11, the deformation or fracture point of the barbell under specific pressure can be analyzed, thereby assessing whether its strength meets the standard.

[0035] Furthermore, a groove 22 is provided on the top of the base plate 1. A threaded rod 20 is rotatably connected inside the groove 22, and a moving block 21 is slidably connected inside the groove 22. The threaded rod 20 and the moving block 21 are threadedly connected. A second motor 12 is fixedly installed on the outer surface of the base plate 1. The end of the threaded rod 20 at the output end of the second motor 12 is fixedly connected. When the second motor 12 is started, its output end drives the threaded rod 20 to rotate. Since the moving block 21 is threadedly connected to the threaded rod 20, the moving block 21 will move laterally along the groove 22 on the base plate 1. This movement drives the base 19 and the snap ring 16 connected to the moving block 21, so that it can be used for barbell bars of different lengths.

[0036] Furthermore, the placement assembly includes elastic locking rings 16, connecting seats 17, springs 18, and bases 19. The tops of the moving block 21 and the base plate 1 are all fixedly connected to the bases 19. The tops of the two bases 19 are each fixedly connected to two connecting seats 17. Elastic locking rings 16 are rotatably connected between the two connecting seats 17. The two elastic locking rings 16 are both arranged in an Ω-shaped structure. Springs 18 are elastically connected between the two sides of the elastic locking rings 16 and the bases 19. Then, the barbell bar to be tested is placed in the placement assembly. The barbell bar is placed in the two Ω-shaped elastic locking rings 16. These locking rings 16 are connected to the bases 19 through the springs 18, ensuring stable support for the barbell bar, while allowing a certain degree of adaptive adjustment to accommodate barbell bars of different diameters.

[0037] Working principle: When the operator needs to use the barbell strength testing device, the second motor 12 is started, and its output end drives the threaded rod 20 to rotate. Since the moving block 21 is threadedly connected to the threaded rod 20, the moving block 21 will move laterally along the slide groove 22 on the base plate 1. This movement drives the base 19 and the locking ring 16 connected to the moving block 21, so that it can be used for barbell bars of different lengths. Then, the barbell bar to be tested is placed in the placement assembly. The barbell bar is placed in two Ω-shaped elastic locking rings 16. These locking rings 16 are connected to the base 19 by springs 18, ensuring stable support of the barbell bar, while allowing a certain degree of adaptive adjustment to accommodate barbell bars of different diameters. Then, the first motor 6 is started, and the output end of the first motor 6 drives one pulley 4 to rotate. Through the transmission of the belt 5, the other pulley 4 also rotates synchronously. The locking block 14 on the outer surface of the belt 5 moves with the belt 5. Since the locking block 14 is fixed to the connecting plate 3, The connection is such that the connecting plate 3 and its detection components (including the load-bearing block 10) move laterally along the first guide rail 7 and the first slider 15 of the connecting frame 2 until the load-bearing block 10 is aligned with the barbell bar at the position to be tested. When the load-bearing block 10 reaches the designated position, the cylinder 8 is activated, and the output end of the cylinder 8 pushes the load-bearing block 10 downward until the load-bearing block 10 contacts the barbell bar and applies pressure. During this process, the pressure sensor 11 monitors and records the pressure value applied by the load-bearing block 10 to the barbell bar in real time. At the same time, the load-bearing block 10 is slidably connected to the second guide rail 9 and the second slider 13 to ensure its stability and accuracy when applying pressure. Based on the data recorded by the pressure sensor 11, the deformation or fracture point of the barbell bar under a specific pressure can be analyzed to assess whether its strength meets the standard. If the barbell bar can withstand the predetermined pressure without significant deformation or fracture, its strength is considered qualified; otherwise, further inspection or replacement is required.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
