Description

Technical Field

[0001] The invention relates to the technical field of boxing sandbags, in particular to a boxing sandbag suspension structure. Background Art

[0002] With the global popularity and development of boxing, punching bags have become indispensable training equipment, whether for high-intensity training for professional athletes or daily exercise for fitness enthusiasts. As a key component supporting the bag and ensuring proper training, the design and functionality of the boxing bag's suspension structure have been continuously optimized. Early simple suspension methods have gradually evolved into structures with high-strength load-bearing and adjustable functions. By utilizing higher-quality suspension materials and innovative connection designs, the bag maintains stability despite impact forces, adapts to different training scenarios and user needs, and provides reliable hardware support for boxing training.

[0003] The boxing sandbag suspension structure is mainly composed of high-strength suspension brackets, connecting components and shock-absorbing and buffering devices. The high-strength suspension brackets are firmly installed on the ceiling or wall to provide reliable support. The connecting components are composed of fixed rods and connectors, which are used to connect with the boxing sandbags. The shock-absorbing and buffering devices are composed of springs and rubber buffer pads, which are installed between the sandbags and the connecting components. When working, the impact force exerted on the sandbag is first absorbed and dispersed by the springs and rubber pads of the shock-absorbing and buffering devices to reduce the transmission of impact force. The connecting components ensure that the sandbag is at an appropriate height. The high-strength suspension bracket relies on a firm installation method to ensure the stability of the overall structure, so that the sandbag can quickly reset after being hit and swinging, and continue to provide stable support for training.

[0004] The shock-absorbing and buffering devices of some current boxing sandbag suspension structures lack multi-dimensional buffering mechanisms and adaptive adjustment functions when in use, resulting in poor shock absorption effect. On the one hand, traditional suspension structures mostly use a single spring or rubber pad for shock absorption. When the sandbag is hit and swings, the impact force can only be weakened in a single direction, and it is unable to effectively disperse the multi-directional force, which can easily cause local wear or even breakage of the chain. On the other hand, the buffering force of the existing shock-absorbing device is fixed, which is difficult to adapt to the striking power of different users. When those with greater strength are training, the shock-absorbing device has limited kinetic energy absorption and will transmit a large amount of impact force to the support frame and wall, affecting the structural stability and building safety. When used by those with less strength, there are problems of excessive shock absorption and sluggish swinging of the sandbag, which seriously reduce the training experience. Long-term use will also shorten the service life of the suspension structure and the sandbag. Therefore, a boxing sandbag suspension structure is proposed to solve the above problems. Summary of the Invention

[0017] The present invention provides a boxing sandbag suspension structure, which has the following beneficial effects:

[0018] 1. In the present invention, in terms of cushioning, shock absorption and adaptive adjustment, when the sandbag is hit and swings during training, the spherical hinge allows the sandbag to rotate freely in three-dimensional space, dispersing the impact force in multiple directions and avoiding excessive local force on the chain. The swing of the sandbag drives the fixed box to rotate, and the universal joint pushes the sliding ring to compress the spring. The spring absorbs and consumes the impact force through elastic deformation, effectively reducing the impact on the support frame and the wall. At the same time, the user can rotate the rotating ring and use the threaded transmission to drive the moving ring to slide up and down, and accurately adjust the spring preload. Whether it is a novice with less strength or a professional player with heavy punches, they can obtain the most suitable cushioning effect by adjusting the preload, significantly improving training comfort and equipment durability.

[0019] 2. In the present invention, in terms of quick disassembly and height adjustment, when installing the boxing sandbag, insert the chain into the bottom of the fixed box, pull the control lever to drive the moving block to slide, compress the spring to store force, and after releasing the control lever, the spring releases energy to push the moving block to reset, so that the limiting column is accurately stuck in the chain gap to achieve stable fixation. The entire installation process only takes a few seconds. When disassembling, pull the control lever again, the limiting column will be separated from the chain, and the sandbag can be easily removed. In addition, by selecting different insertion positions of the chain, the hanging height of the sandbag can be freely adjusted within a certain range. Whether it is a lower height for children's training or a standard height for adult training, it can be quickly adapted. This design greatly improves the convenience of sandbag installation, disassembly and height adjustment, making it convenient for users to replace sandbags or adjust training height according to needs.

[0020] 3. In the present invention, in terms of flexible position adjustment, the control handle at the bottom of the support frame is rotated, and the worm rotates and drives the turbine, which drives the threaded column to rotate. The rotational motion is converted into linear motion of the sliding rod through thread transmission. The sliding rod slides smoothly in the support frame, driving the mobile frame and the sandbag to move as a whole. The adjustment process is smooth and labor-saving. The sandbag can be moved back and forth to the ideal position. After the training, the sandbag can be pushed close to the wall, which greatly reduces the space occupied. During training, it can be flexibly adjusted according to needs. Whether it is the limited space of a family living room or a professional training venue, it can flexibly adapt to different venue layouts, effectively improving space utilization and training flexibility.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 3 、 Figure 4 and Figure 6 The present invention provides an embodiment of a boxing sandbag suspension structure, comprising a boxing bag 1 and a support frame 3. The boxing bag 1 serves as a core training carrier, and multiple chains 2 fixedly connected to the top of the boxing bag 1 serve as load-bearing components. The chains 2 are forged with high-strength alloy steel, and the chain links are precisely riveted, which can withstand huge tensile force and is responsible for stably transferring the weight of the sandbag to the fixing device. The support frame 3 is welded from high-strength carbon steel and is equipped with an anti-slip rubber pad at the bottom to provide stable support for the overall structure. The mobile frame 8 is connected to the support frame 3 by a sliding rail and can be slid and adjusted in the horizontal direction. The user can accurately control the position of the mobile frame 8 by rotating the adjustment knob. The buffer mechanism 6 set at the bottom end of the mobile frame 8 adopts a multi-component collaborative design, which can effectively absorb the impact force when the sandbag is hit and protect the support frame 3 and the wall. The external sliding connection of the chain 2 is connected to the fixed box 4. The fixed box 4 adopts a split opening and closing structure for fixing the chain 2 and realizing rapid installation and disassembly of the sandbag. The docking mechanism 5 set inside the fixed box 4 is the key structure for realizing rapid locking of the chain 2. The adjustment mechanism 9 set inside the support frame 3 is used to adjust the hanging height and position of the sandbag.

[0032] The buffer mechanism 6 includes a fixed column 67, the top of which is fixedly connected to the bottom end of the movable frame 8 by a high-strength bolt. As the main supporting structure of the buffer mechanism 6, the internal sliding connection of the fixed column 67 is connected to the movable ring 65, which can slide smoothly up and down in the fixed column 67. The bottom end of the moving ring 65 is fixedly connected with a spring 2 63. The spring 2 63 is made of a high-elastic alloy material and has excellent fatigue resistance. When the sandbag is hit, it absorbs energy through compression deformation. The bottom end of the spring 2 63 is fixedly connected with a sliding ring 62. The sliding ring 62 can slide in the fixed column 67 to guide the compression and reset of the spring 2 63 to ensure a smooth buffering process. The bottom end of the sliding ring 62 is rotatably connected with a universal joint 61 to adapt to the multi-angle swing of the sandbag after being hit. The top end of the fixed box 4 is rotatably connected with a spherical hinge 64. The spherical hinge 64 adopts a double-bearing structure to further enhance the flexibility of the sandbag's swing and disperse the impact force to avoid excessive local force. An adjustment component 66 is provided on the outside of the moving ring 65. The adjustment component 66 is used to adjust the preload force of the spring 2 63. The outside of the sliding ring 62 is slidably connected to the inside of the fixed column 67 to ensure smooth sliding.

[0033] The bottom end of the universal joint 61 is rotatably connected to the top of the fixed box 4, realizing flexible connection between the fixed box 4 and the buffer mechanism 6. The adjustment component 66 includes a rotating ring 662. The inner side of the rotating ring 662 is provided with a fine thread, which precisely matches the outer thread of the fixed column 67. The position can be adjusted by rotating the rotating ring 662. The bottom end of the rotating ring 662 is rotatably connected to the connecting ring 661. The connecting ring 661 converts the rotational movement of the rotating ring 662 into linear motion and transmits it to the moving ring 65. The inner side of the connecting ring 661 is fixedly connected to two connecting columns 663. A sliding groove is provided inside the fixed column 67. The outer side of the connecting column 663 is slidably connected to the inner side of the sliding groove. By sliding the connecting column 663 in the sliding groove, the moving ring 65 is adjusted up and down, thereby changing the preload force of the spring 2 63. The top end of the spherical hinge 64 is fixedly connected to the bottom end of the moving frame 8, and the outer sides of the two connecting columns 663 are fixedly connected to the outer side of the moving ring 65, ensuring a firm connection between the components.

[0034] Reference Figure 2 、 Figure 4 and Figure 5The docking mechanism 5 includes a moving block 51. The outer portion of the moving block 51 is slidably connected to the inner portion of the fixed box 4 to complete the locking and unlocking of the chain 2. The outer portion of the moving block 51 is fixedly connected to a limiting column 52. The limiting column 52 can tightly clamp the chain links of the chain 2 to prevent it from falling off. The end of the moving block 51 away from the limiting column 52 is fixedly connected to a telescopic column 53. The telescopic column 53 is composed of an inner and outer outer sleeve to provide guidance and support for the sliding of the moving block 51. The outer sleeve of the telescopic column 53 is provided with a spring 54. The spring 54 provides a restoring force during the fixing process of the chain 2. Its elastic coefficient has been strictly calculated, which can ensure rapid reset without damaging the chain 2 due to excessive elastic force. The outer fixed connection of the moving block 51 There is a control rod 55, and the end of the control rod 55 is provided with a non-slip rubber grip, which is convenient for the operator to manually control the sliding of the moving block 51. The outer sliding of the limiting column 52 is connected to the inside of the chain 2 to lock the chain 2. One end of the spring 1 54 is fixedly connected to the end of the moving block 51 away from the limiting column 52, and the other end is fixedly connected to the inside of the fixed box 4 to ensure that the spring 1 54 can effectively push the moving block 51 to reset. The end of the telescopic column 53 away from the moving block 51 is fixedly connected to the inside of the fixed box 4. The top of the support frame 3 is fixedly connected to the diagonal support rod 7. The diagonal support rod 7 and the support frame 3 form a triangular stable structure, which enhances the stability of the support frame 3 and prevents it from shaking or tipping over when the sandbag is hit.

[0035] Reference Figure 1 、 Figure 7 and Figure 8 The adjusting mechanism 9 includes a turbine 91. The outside of the turbine 91 is rotatably connected to the inside of the support frame 3 through a high-precision bearing. As a key transmission component of the adjusting mechanism 9, its tooth shape is specially designed. The internal rotation of the support frame 3 is connected with a worm 93. The worm 93 cooperates with the turbine 91 to realize power transmission. The two adopt an involute tooth shape, which has a smooth transmission and low noise. The outside of the worm 93 is fixedly connected with a control handle 94. The surface of the control handle 94 is provided with an anti-slip texture, which is convenient for the operator to manually adjust the turbine 91 and the worm 93. The outside of the turbine 91 is fixedly connected with a threaded column 92. The threaded column 92 is rotated The worm 93 and the turbine 91 are threadedly connected to each other to ensure the stability of power transmission. There is no slipping even after long-term use. The external sliding connection of the sliding rod 95 is connected to the inside of the support frame 3 to ensure smooth sliding. The external sliding connection of the sliding rod 95 is fixedly connected to the inside of the mobile frame 8. The position of the mobile frame 8 is adjusted by sliding the sliding rod 95 to meet the needs of different usage scenarios.

[0036] Working principle: When using a boxing sandbag, the user can insert the outer parts of the multiple chains 2 at the top of the boxing bag 1 from the bottom end of the fixed box 4, and at the same time pull the control rod 55 to make the outer part of the moving block 51 slide inside the fixed box 4. At this time, the spring 1 54 will be compressed. When the outer part of the chain 2 is inserted into the interior of the fixed box 4, the control of the control rod 55 is canceled. At this time, the compressed spring 1 54 will automatically push the moving block 51 to slide in the opposite direction, and at the same time make the outer part of the limiting column 52 slide into the interior of the chain 2, thereby fixing the position of the chain 2, thereby completing the quick hanging installation of the boxing bag 1. At the same time, the operator can lock different sections of the chain 2 inside the fixed box 4 as needed, thereby completing the adjustment of the hanging height of the boxing bag 1. When the boxing bag 1 needs to be disassembled, by pulling the control rod 55 again, the limiting column 52 will slide out from the inside of the chain 2, thereby canceling the restriction on the chain 2, and finally completing the disassembly of the boxing bag 1. The quick disassembly and assembly of the boxing bag 1 facilitates the replacement or adjustment of the boxing bag 1.

[0037] When the user uses the boxing bag 1 for training, the setting of the spherical hinge 64 ensures that the boxing bag 1 swings normally when hit, and disperses the impact force through the flexible connection to prevent the chain 2 from being worn or broken due to unidirectional force. At the same time, when the boxing bag 1 is hit, the fixed box 4 rotates, and the universal joint 61 pushes the sliding ring 62 to slide inside the fixed column 67. At this time, the spring 2 63 will be compressed, thereby weakening or offsetting the kinetic energy, thereby reducing the impact of the boxing bag 1 on the support frame 3 or the wall when it is hit. At the same time, the operator can rotate the rotating ring 662 so that the rotating ring 662 moves outside the fixed column 67, guiding the sliding of the connecting ring 661, so that the movable ring 65 slides as a whole inside the fixed column 67, thereby adjusting the initial preload force of the spring 2 63 to meet the usage needs of different users.

[0038] The operator can rotate the control handle 94 at the bottom of the support frame 3. The anti-slip knurled design on the surface of the control handle 94 provides a comfortable grip and reliable friction, so that the worm 93 rotates inside the support frame 3. The helical teeth of the worm 93 precisely mesh with the involute teeth of the turbine 91 to form a transmission pair with a self-locking function, which can not only ensure the smoothness of the adjustment process, but also reliably lock the position after the operation is stopped. The rotation of the turbine 91 drives the threaded column 92 coaxially fixed with it to rotate synchronously. The trapezoidal thread of the threaded column 92 cooperates with the threaded pair inside the sliding rod 95 to convert the rotational motion into linear motion. The sliding rod 95 performs precise linear sliding under the guidance of the linear bearing inside the support frame 3. As the sliding rod 95 slides, the movable frame 8 fixed to it moves synchronously to achieve precise adjustment of the position of the boxing bag 1.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
