Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to an anti-bending structure for a squat trainer. Background Technology

[0002] Squats are a fitness exercise, a top-notch movement for building thigh muscles, and consistent practice can also aid in weight loss. Squats are considered essential for increasing leg and glute strength and size, as well as developing core strength, while squat trainers are training devices used to assist users in performing squat exercises.

[0003] Currently, on squat trainers, the main frame's hanging posts and dumbbells are generally not on the same vertical line. When the dumbbells are freely suspended from the main frame's hanging posts, they exert a downward pulling force on the guide rod. This force, acting on the guide rod for a long time, can easily cause the guide rod to bend and deform. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed anti-bending structure for a squat trainer in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A bending prevention structure for a squat trainer includes a support structure. A rotating arm is rotatably connected to the support structure via a suspension column. A weighted dumbbell is mounted on the end of the rotating arm away from the suspension column. A guide rod body is connected to one side of the support structure. A sliding sleeve is slidably fitted onto the guide rod body. The middle section of the rotating arm is fixed to the outer wall of the sliding sleeve via an adjustment component. A limiting rod is fixedly inserted through the end of the rotating arm near the suspension column. One end of the limiting rod extends to the outside of the support structure, and the other end of the limiting rod is fixedly connected to a support rod. A slot is formed on the bottom end of the support rod. A support column is welded and fixed to the support structure below the suspension column. When the weighted dumbbell is not under load, the support rod is engaged with the support column through the slot.

[0007] As a further optimization of this utility model, the support structure includes two symmetrically arranged support plates, the bottom ends of the two support plates are fixedly connected to the same base, the top ends of the two support plates are fixed together by a crossbeam, and the suspension column is installed on the side wall of the adjacent side of the two support plates.

[0008] As a further optimization of this utility model, each of the two support plates is provided with a diagonal brace on the side away from the guide rod body, and the diagonal brace is welded and fixed to the support plate.

[0009] As a further optimization of this utility model, a mounting hole is provided on one end of the rotating arm near the suspension column, and a bearing is embedded inside the mounting hole. The rotating arm is rotatably connected to the suspension column through the bearing.

[0010] As a further optimization of this utility model, the adjustment component includes an oblong hole opened on the middle section of the rotating arm, a connecting rod slidably passing through the oblong hole, and one end of the connecting rod being fixed to the outer wall of the sliding sleeve near the rotating arm.

[0011] As a further optimization of this utility model, the slot has an arc-shaped structure, the inner diameter of the slot is larger than the diameter of the support column, and a rubber buffer pad is fixedly connected to the inner wall of the slot.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When the user finishes training and releases the weighted dumbbells, the dumbbells rotate downwards under their own weight. Before the dumbbells exert an oblique pulling force on the guide rod body, the limiting rod will first fit against the side wall of the support plate to prevent the dumbbells from continuing to rotate. At the same time, the support rod 13 at the other end of the limiting rod will be engaged with the support column through the slot, providing double support for the dumbbells and minimizing the oblique pressure exerted by the dumbbells on the guide rod body, which can easily lead to bending and deformation of the guide rod body over time.

[0014] 2. A sliding sleeve is slidably fitted onto the main body of the guide rod. A waist-shaped hole is opened in the middle section of the rotating arm, and a connecting rod slides through the waist-shaped hole. One end of the connecting rod is fixed to the outer wall of the sliding sleeve near the rotating arm. When the user performs weighted squat training, the connecting rod will drive the sliding sleeve to slide along the height direction of the main body of the guide rod. When the user is exhausted and cannot support the weighted dumbbell, the downward rotation of the weighted dumbbell will be subject to a horizontal component force on the sliding sleeve, increasing the friction between the sliding sleeve and the main body of the guide rod, thus preventing the weighted dumbbell from sliding down directly and easily causing injury to the user.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example

[0022] like Figure 1 - Figure 4 As shown, a squat trainer anti-bending structure for a guide rod includes a support structure, which includes two symmetrically arranged support plates 1. The bottom ends of the two support plates 1 are fixedly connected to the same base 2, and the top ends of the two support plates 1 are fixed together by a crossbeam 3 to form a bracket for support.

[0023] Two support plates 1 are fixedly connected to a suspension column 6 on one side of each other. A rotating arm 7 is installed on the suspension column 6. A mounting hole is opened on the end of the rotating arm 7 near the suspension column 6. A bearing is embedded in the mounting hole. The rotating arm 7 is rotatably connected to the suspension column 6 through the bearing. The bearing not only reduces the frictional resistance when the rotating arm 7 rotates around the suspension column 6, but also reduces the wear of the suspension column 6 and the inner wall of the mounting hole, thereby improving the service life of the suspension column 6 and the rotating arm 7.

[0024] A weighted dumbbell 8 is installed on the end of the rotating arm 7 away from the suspension column 6. When using it, the user can push the weighted dumbbell 8 upward by supporting the weight bar in the middle of the weighted dumbbell 8 with their shoulder to perform weighted squat training.

[0025] A guide rod body 5 is provided on one side of each of the two support plates 1. The bottom end of the guide rod body 5 is fixed to the base 2, and the top end of the guide rod body 5 is bent towards the support plate 1 and fixed to the side wall of the support plate 1. A sliding sleeve 9 is slidably fitted on the guide rod body 5. A waist-shaped hole 10 is opened on the middle section of the rotating arm 7. A connecting rod 11 is slidably inserted into the waist-shaped hole 10. One end of the connecting rod 11 is fixed to the outer wall of the sliding sleeve 9 near the rotating arm 7. When the user is performing weighted squat training, the connecting rod 11 will drive the sliding sleeve 9 to slide along the height direction of the guide rod body 5. When the user is exhausted and cannot support the weighted dumbbell 8, the weighted dumbbell 8 will rotate downward and will be subjected to a horizontal component force on the sliding sleeve 9, increasing the friction between the sliding sleeve 9 and the guide rod body 5, thus preventing the weighted dumbbell 8 from sliding down directly and easily causing injury to the user.

[0026] Both support plates 1 are provided with inclined bracing plates 4 on the side away from the guide rod body 5. The inclined bracing plates 4 are welded and fixed to the support plates 1. The inclined bracing plates 4 are used to reinforce the connection between the support plates 1 and the base 2, and can also improve the bending resistance of the support plates 1.

[0027] A limiting rod 12 is fixedly inserted at one end of the rotating arm 7 near the suspension column 6. One end of the limiting rod 12 extends to the outside of the support plate 1. When the user finishes training and releases the weighted dumbbell 8, the weighted dumbbell 8 drives the rotating arm 7 to rotate downward under its own weight. Before the weighted dumbbell 8 exerts an oblique pulling force on the guide rod body 5, the limiting rod 12 will first fit against the side wall of the support plate 1 to prevent the weighted dumbbell 8 from continuing to rotate. This is to avoid the weighted dumbbell 8 from exerting oblique pressure on the guide rod body 5 through the sliding sleeve 9 when it is stationary. This pressure acting on the guide rod body 5 for a long time can easily lead to the problem of bending and deformation of the guide rod body 5.

[0028] The other end of the limiting rod 12 is fixedly connected to a support rod 13. A slot 14 is provided on the bottom end of the support rod 13. The slot 14 has an arc-shaped structure and its inner diameter is larger than that of the support column 15. A rubber buffer pad is fixedly connected to the inner wall of the slot 14. The support column 15 is welded and fixed to the support structure below the suspension column 6. When the weighted dumbbell 8 is not under force, the support rod 13 is engaged with the support column 15 through the slot 14. Before the limiting rod 12 rotates with the rotating arm 7 to fit with the support plate 1, the buffer rubber pad set in the slot 14 will first fit with the support column 15 to buffer, so as to avoid the limiting rod 12 being deformed by impact. At the same time, the buffer effect can also reduce noise and facilitate user use.

[0029] It should be noted that this squat trainer uses an anti-bending structure for the guide rod. When using it, the user can support the weighted dumbbell 8 by using the lifting bar in the middle of the dumbbell 8 with their shoulders to push the dumbbell 8 upwards for weighted squat training. After finishing the training and releasing the dumbbell 8, the dumbbell 8 will rotate downwards under its own weight. Before the dumbbell 8 exerts an oblique pulling force on the guide rod body 5, the limiting rod 12 will first fit against the side wall of the support plate 1 to prevent the dumbbell 8 from continuing to rotate. At the same time, the slot 14 on the support rod 13 at the other end of the limiting rod 12 will engage with the support column 15. Through the double support of the limiting rod 12 and the support rod 13, the oblique pressure exerted on the guide rod body 5 through the sliding sleeve 9 when the dumbbell 8 is stationary is avoided as much as possible. This pressure acting on the guide rod body 5 for a long time can easily lead to the problem of bending and deformation of the guide rod body 5.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
