Description

Technical Field

[0001] This utility model relates to the field of martial arts training technology, specifically a foldable martial arts flexibility auxiliary frame. Background Technology

[0002] In martial arts and gymnastics, the traditional teaching method for back handsprings and straight back somersaults is to train under the protection of a teacher. The teacher's protection and assistance result in a heavy workload in class, and students are prone to neck injuries when training outside of class without protection. Therefore, it is necessary to train the flexibility of the waist by using an auxiliary frame to assist in the training of waist flexibility.

[0003] A martial arts waist-lifting training frame is disclosed in CN208130385U, comprising a fixed base plate. The fixed base plate has slots at both ends of its upper surface and a screw thread at its center. Leg support plates are located inside the slots. An elastic element is located on one side of each leg support plate. A waist support plate is located between the leg support plates. A reinforcing plate is located at the lower end of the waist support plate. An arc-shaped support plate is located at the lower end of the reinforcing plate. A telescopic device is located at the lower end of the arc-shaped support plate. This utility model has a simple structure, is easy to manufacture, and is readily popularized and promoted. The development and practice of this auxiliary equipment can effectively prevent and reduce sports injuries, making extracurricular training safer and more reliable.

[0004] In the current field of martial arts training, auxiliary training equipment for waist flexibility generally adopts a design consisting of an arc-shaped plate and a mounting base. This arc-shaped plate, through its arched shape, can effectively support the user's waist, thereby helping them to better complete various waist movements during training. However, a significant drawback of this device is its large overall size, which causes inconvenience in transportation after training. Because this device lacks a foldable design, it needs to be moved entirely to one side of the training area when not in use. This is not only physically demanding, but also further restricts the space of the training area due to its large footprint. This spatial limitation may negatively impact the efficiency and comfort of martial arts training, especially in training environments with limited space.

[0005] Therefore, those skilled in the art have provided a foldable martial arts flexibility support frame to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a foldable martial arts flexibility support frame to solve the problem mentioned in the background art that the existing martial arts flexibility support frames are not conducive to folding during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A folding martial arts flexibility aid frame includes: a first folding frame, a second folding frame rotatably connected to the lower end of the first folding frame, a damping shaft for rotation provided between the first folding frame and the second folding frame, a screw hole provided on the inner wall of the first folding frame, and a clamping roller installed inside the first folding frame, a positioning roller fixedly connected to one end of the second folding frame, an arch plate installed between the positioning roller and the clamping roller, and a first grabber connected to the upper end of the arch plate, and a second grabber connected to the lower end of the arch plate.

[0009] As a further improvement of this utility model: the roller is connected to the screw holes on the surface of the first folding frame by bolts, and the screw holes are evenly distributed along the inner wall of the first folding frame.

[0010] As a further improvement of this utility model, the arch plate has an arc-shaped external structure.

[0011] As a further improvement of this utility model: the two ends of the arch plate are fixedly connected to gripper one and gripper two respectively, and the dimensions of gripper one and gripper two match the dimensions of the positioning roller and the clamping roller.

[0012] As a further embodiment of this utility model: the first folding frame and the second folding frame are rotatably connected by a damping pivot, and the outer wall of the second folding frame is rotatably connected to a connecting shaft.

[0013] As a further embodiment of this utility model: a card seat is fixedly connected to the outer wall of the first folding frame, a card is fixedly connected to the surface of the connecting shaft, and a slot is fixedly opened on the surface of the card. The card is rotatably connected to the second folding frame through the connecting shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Through a clever connection of damping shafts, the first and second folding frames are rotatably connected. Clamping rollers and positioning rollers are installed on the structure of the folding frames. These components are crucial, responsible for precisely positioning both ends of the arch plate, ensuring that the arch plate can be stably held in the proper position. To further enhance the reliability of positioning, two carefully designed clamps, one for clamping and one for clamping, are installed at each end of the arch plate. These clamps effectively hold the clamping rollers and positioning rollers, thus ensuring that the arch plate maintains its arched structure during use. The arch plate itself is made of a highly elastic plastic material, which not only provides sufficient... The support helps to arch the board and also provides good support for the user's waist. When the board needs to be disassembled, the operator only needs to open the grab buckle to disengage from the clamping roller and positioning roller. The elastic plastic board will quickly rebound and return to its original flat state using its own elasticity. In addition, the flexible rotating structure between the first and second folding frames can be used to fold the two frames together. This not only makes it convenient to store and carry the board, but also greatly reduces the space occupied in the training area after flexibility training, allowing the area to be quickly restored to a usable state and freeing up space for other training activities.

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a folding martial arts flexibility auxiliary frame, including: a first folding frame 1, a second folding frame 2 rotatably connected to the lower end of the first folding frame 1, a damping shaft 3 for rotation between the first folding frame 1 and the second folding frame 2, a screw hole 4 opened on the inner wall of the first folding frame 1, and a clamping roller 5 installed inside the first folding frame 1, a positioning roller 6 fixedly connected to one end of the second folding frame 2, the first folding frame 1 and the second folding frame 2 are rotatably connected through the damping shaft 3, and a connecting shaft 8 is rotatably connected to the outer wall of the second folding frame 2, a clamping seat 11 is fixedly connected to the outer wall of the first folding frame 1, a clamping member 9 is fixedly connected to the surface of the connecting shaft 8, and a clamping slot 10 is fixedly opened on the surface of the clamping member 9, and the clamping member 9 is rotatably connected to the second folding frame 2 through the connecting shaft 8;

[0023] Specifically, the damping shaft 3 facilitates the rotation and folding of the first folding frame 1 and the second folding frame 2 together. The damping shaft 3 consists of an inner shaft, an outer shaft, and a damping layer, which improves the durability of the rotation structure between the first folding frame 1 and the second folding frame 2 and extends its service life. The locking piece 9 rotates through the connecting shaft 8. After rotation, the locking slot 10 on the surface of the locking piece 9 is locked onto the locking seat 11, thereby locking the first folding frame 1 and the second folding frame 2 and preventing instability during use. After the first folding frame 1 and the second folding frame 2 are unfolded, the locking piece 9 further improves the stability of the first folding frame 1 and the second folding frame 2.

[0024] An arch plate 7 is installed between the positioning roller 6 and the clamping roller 5. The upper end of the arch plate 7 is connected to a first gripper 12, and the lower end of the arch plate 7 is connected to a second gripper 13. The clamping roller 5 is connected to the screw holes 4 on the surface of the first folding frame 1 by bolts. The screw holes 4 are evenly distributed along the inner wall of the first folding frame 1. The arch plate 7 has an arc-shaped structure. The two ends of the arch plate 7 are fixedly connected to the first gripper 12 and the second gripper 13, respectively. The dimensions of the first gripper 12 and the second gripper 13 match the dimensions of the positioning roller 6 and the clamping roller 5.

[0025] Specifically, the first folding frame 1 has screw holes 4 inside. The two ends of the positioning roller 6 are installed on the first folding frame 1 by screws. There are multiple sets of screw holes 4. The height of the arch plate 7 is adjusted according to the actual flexibility training situation. There are two sets of clamping rollers 5 to facilitate adjustment with the arch plate 7. The positioning roller 6 is installed on the second folding frame 2. The positioning roller 6 is also fixed in place by screws, which is convenient for installation and disassembly. The clamps at both ends of the arch plate 7 are set with the openings of the clamps being set in the opposite direction. They are clamped and pressed from the inside of the positioning roller 6 and the clamping roller 5. When the arch plate 7 bears the weight, it will press down on the arch plate 7, causing the clamps at both ends of the arch plate 7 to push outward, thereby pressing the two ends of the arch plate 7 against the positioning roller 6 and the clamping roller 5, thus completing the positioning of the arch plate 7.

[0026] The working principle of this utility model is as follows:

[0027] When using this utility model, firstly, the first folding frame 1 and the second folding frame 2 are unfolded via the damping shaft 3. According to actual usage requirements, the position of the arch plate 7 is adjusted. The clamping roller 5 is installed in the screw hole 4 on the inner wall of the first folding frame 1 using bolts, and the positioning roller 6 is installed in the screw hole 4 on the inner wall of the second folding frame 2 using bolts. One end of the arch plate 7, the second clamp 13, is engaged with the positioning roller 6, and the other end of the arch plate 7, the first clamp 12, is engaged via the clamping roller 5. The two ends of the arch plate 7 are respectively equipped with the first clamp 12 and the second clamp 13. The clamps adopt a reverse opening design; when the arch plate 7 is subjected to force, it will press downwards, causing the clamps at both ends to push outwards, thus engaging with the positioning roller 6. The positioning roller 6 and the clamping roller 5 are tightly pressed together to stabilize the position of the arch plate 7. At the same time, according to the needs of flexibility training, the position of the positioning roller 6 and the clamping roller 5 are adjusted by adjusting the position of the screw hole 4, thereby changing the position of the two ends of the arch plate 7 and shortening the distance between the two ends of the arch plate 7 after arching. This changes the height of the arch apex of the arch plate 7 to adapt to different training intensities. In addition, when disassembling, the first folding frame 1 and the second folding frame 2 are not in use. The clamping piece 9 is removed from the clamping seat 11, and the grabs at both ends of the arch plate 7 are pried open from the positioning roller 6 and the clamping roller 5. The arch plate 7 will elastically return to its original position and be folded by the damping pivot 3 to reduce the space occupied and facilitate carrying and storage.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
