Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, and more specifically to a multifunctional combined physical training sandbag. Background Technology

[0002] Physical training sandbags are formed by filling them with heavy materials such as sand, quartz sand, and granular cotton, and are covered with wear-resistant and leak-proof materials on the outside. Therefore, they can be used by vertically hitting them by hanging them on the ceiling of a gym or home to help improve the body's explosive power and physical fitness. In summary, the inventors have found that existing physical training sandbags have the following main defects: Due to the relatively simple structure of current physical training sandbags, which are only fixedly suspended from the ceiling at the top and can only be used to improve explosive power, they are difficult to play other roles. Therefore, they are difficult to match the characteristics of multi-functional combined physical training. Furthermore, when used for suspension and striking, the sandbag swings forward, and the swaying amplitude increases due to its own weight and inertia. This can easily cause the sandbag to hit the user during long training sessions, thus increasing the safety hazards during training. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is: a multifunctional combined physical training sandbag, the structure of which includes: a sandbag body, a load-bearing structure, a restraining base, a reinforcing top plate, and a suspension component. The edge of the sandbag body is fixed to the load-bearing structure, and the bottom is mutually restrained by the restraining base and the upper reinforcing top plate. The suspension component at the center of the reinforcing top plate is set in a vertical position.

[0004] As a further improvement of the present invention, the restraining base is provided with an anti-slip plate, a solid block, a center block, a rocker arm, and a weight adjuster. The anti-slip plate covers the lower end of the solid block, and the center block at the upper end of the solid block determines the position of the rocker arm. The weight adjuster on the upper edge of the solid block is spaced to match the rocker arm.

[0005] As a further improvement of the present invention, the load-bearing structure is provided with a flexible plate, a fusion block, a handrail, a groove, and a connecting block. The flexible plate is connected to the sandbag body through the fusion block, and the handrails at the upper and lower positions are fixed to the upper and lower positions of the sandbag body through the connecting block. The handrails and the groove are integrated.

[0006] As a further improvement of the present invention, the position of the center block is determined by the anti-slip plate and solid block of the restraining base of the sandbag body. The rocking rod of the center block is connected to the lower center of the sandbag body and restrains the upper suspension component. At the same time, the load-bearing structure contacts the back of the human body using a flexible plate after the sandbag body is detached from the suspension component and the restraining base, while the handrail is used for hand gripping.

[0007] As a further improvement of the present invention, the sandbag body is set in a vertical orientation and is installed on the ceiling by a suspension device with a reinforced top plate. The contact position between the load-bearing structure and the sandbag body is arc-shaped, and the restraining base is set in a vertical orientation.

[0008] As a further improvement of the present invention, a friction layer is provided at the contact position between the anti-slip plate and the ground to increase the friction with the ground, and an internal thread is provided inside the center block of the solid block to allow the rocking rod to be adjusted in height and to be disassembled from the lower end of the sandbag body. There are four sets of weight adjusters, which are set in four directions.

[0009] As a further improvement of the present invention, the flexible plate is made of silicone and is integrated with the sandbag body through a fusion block. There are two sets of handrails set in a symmetrical orientation, and the connecting block is in a protruding shape, so that the handrails are embedded inside the sandbag body.

[0010] As a further improvement of the present invention, the weight adjuster is also provided with a locking bolt, the upper end of the locking bolt is provided with a balance disc, a locking groove is opened at the center of the balance disc to allow the adjusting bolt to be inserted, the upper end of the adjusting bolt is provided with a rotating block, and the upper end of the rotating block is provided with an insert block.

[0011] As a further improvement of the present invention, the locking bolt is perpendicular to the balance disc and the locking groove extends into the interior of the locking bolt. The adjusting bolt is threadedly connected to the locking groove and the height is adjusted by rotating the insert block.

[0012] As a further improvement of the present invention, the flexible plate is also provided with a contact layer, the left and right ends of the contact layer are connecting ends, and a buckle and a positioning block are provided on the connecting ends. A restraining strap is connected to the positioning block, and a buckle is connected to the other end of the restraining strap.

[0013] As a further improvement of the present invention, the surface of the contact layer is polished and the buckles and positioning blocks at the connecting ends of the left and right ends are set in a symmetrical orientation. The binding strap of the positioning block is engaged with the buckle through the buckle.

[0014] As a further improvement of the present invention, the lower end of the sandbag body is also provided with a partition plate, and the partition plate has slots and edge grooves at the center and edge positions. Protective sleeves are also provided at the slots and edge grooves, and a bracket is connected through the protective sleeves.

[0015] As a further improvement of the present invention, the partition plate is circular in shape and the slots and edge grooves are set in a vertical orientation. The protective sleeve covers the edges of the slots and edge grooves and is positioned by a bracket.

[0016] As a further improvement of the present invention, the bracket is further provided with a vertical frame, an arc-shaped frame, and a clamping block. One end of the vertical frame is fixedly connected to the clamping block, and both ends of the arc-shaped frame are fixedly connected to the clamping block.

[0017] As a further improvement of the present invention, the other end of the vertical frame is connected to the protective sleeve of the slot, and the arc-shaped frame is distributed at the edge of the partition plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention is based on the restraint base and weight-bearing structure set on the main body of the sandbag. The solid block and anti-slip plate of the restraint base can make the shaking rod and weight adjuster vertically positioned. The shaking rod is connected to the bottom center of the main body of the sandbag and restrains the upper suspension, thus limiting the shaking range after the impact and increasing the limit of the rebound range, ensuring the safety factor during training. At the same time, after the main body of the sandbag is separated from the suspension and restraint base, the weight-bearing structure can be placed on the back of the human body for weight training. Therefore, a multi-functional combination safety training effect can be achieved.

[0019] 2. This invention improves upon the weight adjuster and flexible plate. The position of the adjusting bolt is determined by the locking bolt and balance disc. The adjusting bolt, through its upper rotating block, allows the insert to embed into the lower edge of the sandbag body. The insert can be embedded into the lower end of the sandbag body according to the actual strength training situation. The locking restraint at the center and edge allows the sandbag body to shake under impact of different forces, thus achieving the weight-increasing training effect. During weight training, after the flexible plate contacts the back of the user, the restraint straps on the contact layer can be pulled after the handrail contacts the hand, allowing the locking block to embed into the buckle, forming a stable connection with the user and preventing the sandbag from falling during training. This further improves the effectiveness of the training sandbag.

[0020] 3. This invention improves upon the bottom of the sandbag body by using a partition plate to cover the bottom of the sandbag body. The slots and edge grooves of the partition plate allow the rocking rod and weight adjuster to be inserted, avoiding the weight loss caused by the continuous falling of internal weights when directly inserted into the sandbag body. This improves the stability of the sandbag during use. At the same time, the protective sleeves set on the edges of the edge grooves and slots can be reinforced by a bracket. The bracket can be positioned vertically and along the edges to prevent the hole from enlarging and improve the connection accuracy with the weight adjuster and rocking rod.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 5 As shown: This invention provides a multifunctional combined physical training sandbag. Its structure includes: a sandbag body 1, a load-bearing structure 2, a restraining base 3, a reinforced top plate 4, and a suspension component 5. The edge of the sandbag body 1 is fixed to the load-bearing structure 2, and the bottom is restrained by the restraining base 3 and the upper reinforced top plate 4. The suspension component 5 at the center of the reinforced top plate 4 is set in a vertical position.

[0030] The restraint base 3 is provided with an anti-slip plate 31, a solid block 32, a center block 33, a rocking rod 34, and a weight adjuster 35. The anti-slip plate 31 covers the lower end of the solid block 32, and the center block 33 at the upper end of the solid block 32 determines the position of the rocking rod 34. The weight adjuster 35 on the upper edge of the solid block 32 is spaced to fit the rocking rod 34.

[0031] The load-bearing structure 2 includes a flexible plate 21, a fusion block 22, a handrail 23, a groove 24, and a connecting block 25. The flexible plate 21 is connected to the sandbag body 1 through the fusion block 22, and the handrail 23 at the top and bottom is fixed to the upper and lower edges of the sandbag body 1 through the connecting block 25. The handrail 23 and the groove 24 are integrated.

[0032] The position of the center block 33 is determined by the anti-slip plate 31 and solid block 32 of the restraining base 3 of the sandbag body 1. The rocking rod 34 of the center block 33 is connected to the lower center of the sandbag body 1 and restrains the upper suspension 5. At the same time, the load-bearing structure 2, based on the sandbag body 1 being separated from the suspension 5 and the restraining base 3, uses the flexible plate 21 to contact the back of the human body, while the handrail 23 is used for hand gripping.

[0033] The sandbag body 1 is set in a vertical orientation and is installed on the ceiling by the suspension part 5 of the reinforced top plate 4. The contact position between the load-bearing structure 2 and the sandbag body 1 is arc-shaped, and the restraining base 3 is set in a vertical orientation.

[0034] The anti-slip plate 31 has a friction layer at the contact point with the ground to increase the friction with the ground. The center block 33 of the solid block 32 has an internal thread to allow the rocker arm 34 to be adjusted in height and to be disassembled from the lower end of the sandbag body 1. The weight adjuster 35 has four sets and is set in four directions.

[0035] The flexible plate 21 is made of silicone and is integrated with the sandbag body 1 by means of the fusion block 22. The handrail 23 is provided in two sets in a symmetrical position. The connecting block 25 is in a protruding shape, so that the handrail 23 is embedded inside the sandbag body 1.

[0036] The weight adjuster 35 is also provided with a locking bolt 351. The upper end of the locking bolt 351 is provided with a balance disc 352. The locking groove 353 opened at the center of the balance disc 352 allows the adjusting bolt 354 to be embedded. The upper end of the adjusting bolt 354 is provided with a rotating block 355, and the upper end of the rotating block 355 is provided with an insert block 356.

[0037] The locking bolt 351 is perpendicular to the balance disc 352 and the locking groove 353 extends into the locking bolt 351. The adjusting bolt 354 is threadedly connected to the locking groove 353 and the height is adjusted by the rotating block 355 driving the insert block 356.

[0038] The flexible board 21 is also provided with a contact layer 211. The left and right ends of the contact layer 211 are connecting ends 212. A buckle 213 and a positioning block 214 are provided on the connecting ends 212. A restraint strap 215 is connected to the positioning block 214. A buckle 216 is connected to the other end of the restraint strap 215.

[0039] The contact layer 211 has a polished surface and the buckles 213 and positioning blocks 214 of the connecting ends 212 at the left and right ends are set in a symmetrical orientation. The binding strap 215 of the positioning block 214 is engaged with the buckle 213 through the buckle 216.

[0040] The specific functions and operation procedures of this embodiment are as follows: In this invention, the multifunctional combined physical training sandbag has a main body 1 as its core. The main body 1 can be mutually restrained by the restraining base 3 and the suspension part 5 of the top reinforced plate 4, avoiding the dangerous situation caused by the sandbag shaking over a wide range after being hit. The limited rebound range improves the safety factor during training. After the top reinforced plate 4 covers the upper part of the main body 1, it can improve the connection stability with the suspension part 5 and prevent quality problems such as peeling caused by the direct connection of the suspension part 5 to the upper part of the leather sandbag main body 1, thus improving the use effect of the main body 1. After the main body 1 is separated from the restraining base 3 and the suspension part 5 of the top reinforced plate 4, it can be carried on the body by the load-bearing structure 2. The sandbag is placed on the back for weight training, thus achieving a multi-functional combined physical fitness and safety training effect. After the solid block 32 of the base 3 contacts the ground via the bottom anti-slip plate 31, the upper center block 33 of the solid block 32 determines the position of the rocking rod 34, allowing the rocking rod 34 to connect with the bottom center of the sandbag body 1, thereby limiting the shaking range. When additional weight training is needed, the weight can be increased using the edge weight adjuster 35. The locking bolt 351 of the weight adjuster 35 positions the balance disc 352 at the edge of the solid block 33, and the locking groove 353 of the balance disc 352 allows the adjusting bolt 354 to carry the rotating block 355 for height adjustment (the overall length of the adjusting bolt 354 conforms to the sandbag). The distance between the main body 1 and the solid block 32 is consistent with the material of the rocking arm 34, which is also a rubber product. It can be bent and rocked due to its flexibility and can be easily replaced during subsequent maintenance. Then, the insert block 356 is embedded into the lower edge of the sandbag main body 1. Therefore, the lower end of the sandbag main body 1 is not only restrained by the rocking arm 34, but also pushed by the weight adjuster 35 to generate greater striking force. This can form a weighted striking training effect, thus improving the use effect of the training sandbag. After the sandbag main body 1 is removed from the fixed position of the restraint base 3 and the suspension 5, it can be used for weighted training through the weighted structure 2. The flexible plate 21 of the weighted structure 2 will be connected to the fusion block 22, and the two The handrail 23 is installed on the edge of the sandbag body 1 via the connecting block 25. After the flexible plate 21 comes into contact with the back of the human body, the hands can grip the handrail 23 through the groove 24 to carry the sandbag body 1 on the back, thus enabling weight training. At the same time, after the contact layer 211 of the flexible plate 21 comes into contact with the back of the human body, the connecting ends 212 on both sides can be connected by the buckle 213 to the locking block 216 at one end of the restraint strap 215 of the positioning block 214. Thus, after the upper body is restrained by the restraint strap 215, the stability of the weight training is improved, and the sandbag body 1 is prevented from falling off the back of the human body during the training process. Therefore, the intensity of the training sandbag is further improved.

[0041] Example 2: Figures 6 to 7 As shown: This invention provides a multifunctional combined physical training sandbag. Its structure includes a partition plate 11 at the lower end of the sandbag body 1, with slots 12 and edge grooves 13 opened at the center and edge of the partition plate 11, and protective sleeves 14 are provided at the slots 12 and edge grooves 13, and a bracket 15 is connected through the protective sleeves 14.

[0042] The partition plate 11 is circular in shape, and the slot 12 and edge groove 13 are both set in a vertical orientation. The protective sleeve 14 covers the edges of the slot 12 and edge groove 13 and is positioned by the bracket 15.

[0043] The bracket 15 is further provided with a vertical frame 151, an arc frame 152, and a clamping block 153. One end of the vertical frame 151 is fixedly connected to the clamping block 153, and both ends of the arc frame 152 are fixedly connected to the clamping block 153.

[0044] The vertical frame 151 is connected at one end to the protective sleeve 14 of the slot 12, and the arc-shaped frame 152 is distributed at the edge of the partition plate 11.

[0045] The specific functions and operation procedures of this embodiment are as follows: In this invention, the partition plate 11 at the lower end of the sandbag body 1 covers the lower end of the sandbag body 1. The slots 12 and edge grooves 13 on the partition plate 11 allow the rocking rod 34 and weight adjuster 35 to be embedded, preventing damage to the bottom of the sandbag body 1 caused by direct insertion. This avoids damage to the bottom of the sandbag body 1 caused by frequent adjustments and improves the overall quality of the sandbag body 1. At the same time, the protective sleeves 14 on the edges of the slots 12 and edge grooves 13 can be precisely positioned by the bracket 15, which also prevents the hole diameter from enlarging due to frequent insertion. This improves the strength of the sandbag body 1. The bracket 15 can support and clamp the edges of each protective sleeve 14 by the clamps 153 on the vertical frame 151 and the arc frame 152. The complete fixation effect avoids displacement and enlargement of the hole diameter, further improving the quality of the training sandbag.

[0046] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
