Description

Technical Field

[0001] This utility model relates to a hip thrust trainer, belonging to the technical field of training equipment. Background Technology

[0002] The hip thrust is an excellent exercise for developing the glutes and stimulating the hamstrings, front thighs, and adductor muscles. It helps develop overall strength in the glutes and legs. Throughout the movement, the glutes are constantly engaged, and back strength is not a limiting factor. In other popular exercises for training the glutes, the ability of the back to support the load is often a limiting factor in the training load, but the hip thrust does not have this limitation, so it allows the glutes to bear the maximum load.

[0003] An existing patent (CN218516049U) describes a hip thrust trainer. This device adjusts the height of the limiting plate according to different user body parameters to prevent the user's lower back from protruding upwards during hip thrust exercises, thus solving the problem of excessive compensation of the lower back muscles caused by incorrect hip thrust movements. The position, height, and weight of the dumbbell bench are all adjustable to meet different user needs. However, while this device allows adjustment of the dumbbell bench, the adjustment method using only the limiting mechanism is not precise enough or convenient. Furthermore, the dumbbell bench used in this device, as well as in existing technologies, is fixed and cannot automatically adjust according to changes in the body shape during hip thrusts, which can easily cause compression of the lower back during hip thrusts, affecting lower back health. In addition, the method of adjusting the training intensity by the number of weight plates in this device is not convenient enough, and the weight variation of the weight plates is limited, making effective weight adjustment impossible. Utility Model Content

[0004] The purpose of this invention is to provide a hip thrust trainer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hip thrust trainer includes a base, a dumbbell bench, and a fixed frame. A threaded shaft is rotatably connected to the middle of the left inner side of the base. A sliding support is spirally connected to the outer side of the threaded shaft. A lifting support is slidably connected to the upper end of the sliding support. A dumbbell bench is rotatably connected to the upper end of the lifting support. The front and rear ends of the upper right side of the base are fixedly connected to the fixed frame. A weight plate is slidably connected to the middle of the inner side of the fixed frame. A push rod is connected to a rotating wheel on the inner side of the weight plate. An adjusting pull plate is provided below the weight plate. The adjusting pull plate is slidably connected to the fixed frame. A weight spring is provided between the adjusting pull plate and the weight plate.

[0007] Furthermore, a first turntable is rotatably connected to the middle position of the left end of the base, and the first turntable is fixedly connected to the threaded shaft. Limiting slide rails are fixedly connected to the front and rear ends of the upper left side of the base, and the limiting slide rails are slidably connected to the sliding support.

[0008] Furthermore, a second turntable is rotatably connected to the middle position of the lower inner side of the lifting support frame. A first adjusting screw is fixedly connected to the lower end of the second turntable. A fixed sleeve is screwed to the outer side of the first adjusting screw. The fixed sleeve is fixedly connected to the sliding support frame. Limiting plates are fixedly connected to the front and rear sides of the upper end of the sliding support frame. The limiting plates are slidably connected to the lifting support frame.

[0009] Furthermore, the rotating shaft surface between the dumbbell bench and the lifting support is covered with a torsion spring, and the outer torsion arm of the torsion spring is fixedly connected to the lifting support and the dumbbell bench respectively.

[0010] Furthermore, the upper left and upper right ends of the inner side of the fixed frame are fixedly connected to limit rods, which are slidably connected to the load-bearing plate. A second adjusting screw is screwed to the middle position of the upper end of the fixed frame, and an adjusting limiting plate is rotatably connected to the lower end of the second adjusting screw. The adjusting limiting plate is slidably connected to the limit rod.

[0011] Furthermore, a bidirectional screw is rotatably connected inside the lower end wall of the fixed frame, a third turntable is fixedly connected to the left end of the bidirectional screw, a transmission block is helically connected to the outer side of the bidirectional screw, the transmission block is slidably connected to the fixed frame, a transmission rod is rotatably connected to the upper end of the transmission block, and the transmission rod is rotatably connected to the adjusting pull plate.

[0012] Furthermore, hooks are fixedly connected to the lower end of the load-bearing plate and the upper end of the adjusting pull plate, and the hooks are slidably connected to the load-bearing spring.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a first turntable to rotate a threaded shaft, allowing the sliding support to move left and right along the limiting rail. The rotation of a second turntable rotates a first adjusting screw, which, under the limiting action of a limiting plate, allows for vertical adjustment of the lifting support. This enables rapid and precise adjustment of the dumbbell bench's horizontal position and height, ensuring effective hip thrust training. Furthermore, a torsion spring allows the dumbbell bench to rotate according to body movement during hip thrust exercises, preventing single-line compression of the back caused by a fixed bench. The design utilizes a weight spring that can be hooked between the weight plate and the adjusting plate, allowing the weight spring to replace the barbell plates. Rotation of the third turntable causes the bidirectional screw to rotate, which in turn drives the transmission rod, stretching the weight spring through the adjusting plate. This allows for adjustment of the weight intensity, preventing the addition or removal of individual barbell plates from affecting the weight adjustment effect and improving the ease of weight adjustment. Rotation of the second adjusting screw allows the adjusting limit plate to be adjusted up and down, thus limiting the movement during hip lifts and ensuring the effectiveness of hip thrust training.

[0023] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0024] A hip thrust trainer includes a base 1, a dumbbell bench 5, and a fixed frame 6. A threaded shaft 2 is rotatably connected to the middle of the left inner side of the base 1. A sliding support 3 is helically connected to the outer side of the threaded shaft 2. A lifting support 4 is slidably connected to the upper end of the sliding support 3. The dumbbell bench 5 is rotatably connected to the upper end of the lifting support 4. A first turntable 11 is rotatably connected to the middle of the left inner side of the base 1 and is fixedly connected to the threaded shaft 2. Limiting slide rails 12 are fixedly connected to the front and rear ends of the upper left side of the base 1, and are slidably connected to the sliding support 3. A second turntable 13 is rotatably connected to the middle of the lower inner side of the lifting support 4. A first adjusting screw 14 is fixedly connected to the lower end of the second turntable 13, and a fixed sleeve 15 is helically connected to the outer side of the first adjusting screw 14. The fixed sleeve 15 is fixedly connected to the sliding support 3. The upper front and rear sides of the sliding support 3 are fixedly connected to the lifting support 4. A limiting plate 16 is fixedly connected to the lifting support frame 4. The rotating shaft surface between the dumbbell bench 5 and the lifting support frame 4 is covered with a torsion spring 17. The outer torsion arm of the torsion spring 17 is fixedly connected to the lifting support frame 4 and the dumbbell bench 5 respectively. The rotation of the first turntable 11 enables the threaded shaft 2 to rotate, thereby allowing the sliding support frame 3 to move left and right along the direction of the limiting slide rail 12. The rotation of the second turntable 13 enables the first adjusting screw 14 to rotate, and under the limiting action of the limiting plate 16, the lifting support frame 4 can be adjusted up and down. This allows for quick and precise adjustment of the horizontal position and height of the dumbbell bench 5, ensuring the effectiveness of hip thrust training. The torsion spring 17 also allows the dumbbell bench 5 to rotate according to body shape changes during hip thrust training, thus avoiding single-line compression of the back caused by the dumbbell bench 5 being fixed.

[0025] Please refer to Example 2 Figure 1 , Figure 2 and Figure 5The difference between this embodiment and Embodiment 1 is as follows: A fixed frame 6 is fixedly connected to the front and rear ends of the upper right side of the base 1. A load-bearing plate 7 is slidably connected to the inner side of the fixed frame 6 near the middle position. A push rod 8 is connected to the inner rotating wheel of the load-bearing plate 7. An adjusting pull plate 9 is provided below the load-bearing plate 7, and the adjusting pull plate 9 is slidably connected to the fixed frame 6. A load-bearing spring 10 is provided between the adjusting pull plate 9 and the load-bearing plate 7. Limiting rods 18 are fixedly connected to the upper left and upper right ends of the inner side of the fixed frame 6, and the limiting rods 18 are slidably connected to the load-bearing plate 7. A second adjusting screw 19 is spirally connected to the middle position of the upper end of the fixed frame 6. An adjusting limiting plate 20 is rotatably connected to the lower end of the second adjusting screw 19, and the adjusting limiting plate 20 is slidably connected to the limiting rod 18. A bidirectional screw 21 is rotatably connected to the inner wall of the lower end of the fixed frame 6. A third turntable 22 is fixedly connected to the left end of the bidirectional screw 21. A transmission block 23 is spirally connected to the outer side of the bidirectional screw 21. The transmission block 23 is slidably connected to the fixed frame 6. The upper end of the transmission block 23 is rotatably connected to the transmission rod 24. The transmission rod 24 is rotatably connected to the adjusting plate 9. The lower end of the weight plate 7 and the upper end of the adjusting plate 9 are both fixedly connected to the hooks 25. The hooks 25 are slidably connected to the weight spring 10. The weight spring 10 can be hung on the hooks 25 between the weight plate 7 and the adjusting plate 9, so that the weight spring 10 can replace the barbell plates. By rotating the third turntable 22, the bidirectional screw 21 can be rotated, which in turn allows the transmission block 23 to drive the transmission rod 24 to rotate, so that the adjusting plate 9 can stretch the weight spring 10, thereby adjusting the load intensity. This avoids the effect of load adjustment caused by adding or removing barbell plates individually, and improves the convenience of load adjustment. By rotating the second adjusting screw 19, the adjusting limit plate 20 can be adjusted up and down, thereby limiting the movement when lifting the hips and ensuring the effect of hip thrust training.

[0026] The working principle of this utility model is as follows: When in use, the rotation of the first turntable 11 causes the threaded shaft 2 to rotate, allowing the sliding support 3 to move left and right along the limiting slide rail 12. The rotation of the second turntable 13 causes the first adjusting screw 14 to rotate, and under the limiting action of the limiting plate 16, the lifting support 4 can be adjusted up and down. This allows for rapid and precise adjustment of the horizontal position and height of the dumbbell bench 5, ensuring the effectiveness of hip thrust training. Furthermore, the torsion spring 17 allows the dumbbell bench 5 to rotate according to body shape changes during hip thrust training, thus preventing single-line compression of the back caused by a fixed dumbbell bench 5. The weight spring 10 is used to hang on the hook 25 between the weight plate 7 and the adjusting plate 9, allowing it to replace the barbell plates. The rotation of the third turntable 22 causes the bidirectional screw 21 to rotate, which in turn causes the transmission block 23 to drive the transmission rod 24 to rotate, so that the adjusting plate 9 can stretch the weight spring 10. This allows for adjustment of the load intensity, preventing the addition or removal of individual barbell plates from affecting the load adjustment effect and improving the convenience of load adjustment. The rotation of the second adjusting screw 19 allows the adjusting limit plate 20 to be adjusted up and down, thus limiting the movement during hip lifts and ensuring the effectiveness of hip thrust training.
