[0019] In other aspects, this embodiment also provides a fitness sandbag mounting frame based on big health, such as Figure 5-7As shown, two groups of control boxes 13 are fixedly connected to the side of a group of sleeves 3, and the control boxes 13 and the sleeves 3 are interconnected. A gear 14 is arranged inside the control box 13, and the central axis of the gear 14 is connected to the inner wall of the control box 13 through a bearing. The surface of the pillar 2 located inside the sleeve 3 is evenly provided with tooth grooves 15, and the tooth grooves 15 and the gear 14 are meshed with each other.

[0020] Further, the control box 13 is provided with a second gear 16 inside, the second gear 16 and the gear 1 14 are meshed with each other, the central axis of the second gear 16 is connected to the inner wall of the control box 13 through a bearing, the central axis of the back of the second gear 16 passes through the control box 13 and extends to the outside of the control box 13, the back of the control box 13 is provided with a third gear 17, the third gear 17 is fixedly connected to the central axis of the second gear 16, the back of the control box 13 is provided with a clamping rod 18, the side of the clamping rod 18 is fixedly connected with a pressing plate 19, and the top of the clamping rod 18 A counterweight block is fixedly connected, the weight of the counterweight block fixed on the surface of the clamping rod 18 is greater than the weight of the pressing plate 19, the clamping rod 18 and the pressing plate 19 have the same length, and the connection between the clamping rod 18 and the pressing plate 19 is connected to the control box 13 through a bearing. A plurality of groups of special-shaped tooth blocks are fixedly connected to the surface of the gear three 17, and the cross-section of the special-shaped tooth blocks is a right-angled trapezoid. The clamping rod 18 extends to conflict with the tooth blocks fixed on the surface of the gear three 17, and the special-shaped tooth blocks are all obliquely distributed on the surface of the gear three 17 in a circular trajectory, and the special-shaped tooth blocks are oriented in the counterclockwise direction.

[0021] In the specific implementation of this embodiment, when the user uses the device, the user can pull the pillar 2 above the sleeve 3 to drive the pillar 2, the mounting plate 8 and the hanging plate 9 to move upward, thereby adjusting the height of the sandbag. The pillar 2 drives the gear 1 14 to rotate clockwise through the tooth groove 15, and the gear 1 14 drives the gear 2 16 and the gear 3 17 to rotate counterclockwise. When the gear 3 17 rotates, the tooth block on the surface conflicts with the clamping rod 18, because the tooth block is distributed in the counterclockwise direction on the surface of the gear 3 17, and the tooth block is a right-angled trapezoid. When the tooth block conflicts with the clamping rod 18, the tooth block contacts the clamping rod 18. The tooth block drives the lever 18 to rotate upward, so that the lever 18 does not hinder the rotation of the gear three 17, and the lever 18 is always in contact with the tooth block by gravity, and the gear three 17 can rotate freely. When the user pulls the pillar 2 to a suitable position, gravity drives the pillar 2 to descend, and drives the gear one 14, the gear two 16 and the gear three 17 to rotate in the opposite direction through the tooth groove 15. At this time, the gear three 17 conflicts with the lever 18, so that the gear three 17 cannot rotate freely, thereby locking the gear two 16 and the gear one 14, and fixing the position of the pillar 2 through the tooth groove 15. When the user needs to store or adjust the position of the sandbag downward, the user presses the button 19 to drive the clamping rod 18 and the button 19 to rotate clockwise. At this time, the clamping rod 18 is no longer in contact with the gear 3 17 and the tooth block. Then the pillar 2, the mounting plate 8 and the hanging plate 9 can move freely, so that the user can adjust the sandbag downward or store the pillar 2 into the sleeve 3. Then the user releases the button 19. Because the weight of the clamping rod 18 and the accessory block on its surface is greater than the weight of the button 19, when the user releases the button 19, the clamping rod 18 is driven by gravity to rotate counterclockwise, so that The clamping rod 18 again conflicts with the tooth block on the gear three 17. This structure allows the user to adjust the height of the device through simple operation, thereby adjusting the height of the sandbag, so that the device can freely adjust the position of the sandbag according to the height of the user, so that the sandbag can be located in a suitable position for use, avoiding the situation where the position of the sandbag cannot be adjusted, resulting in the user being unable to fully and reasonably use his limbs for exercise during striking exercises. The adjustment method is simple, and after use, the upper and lower sets of pillars 2 can be retracted into the sleeve 3, which greatly reduces the space occupied by the device.

[0022] Working principle: In summary, when the user uses the device, the connecting rod between the handheld sleeve 3 is pulled upward, driving the sleeve 3 to move upward, and the sleeve 3 drives the end of the support rod 4 connected to the sleeve 3 to move upward, thereby driving the other end of the support rod 4 to move forward, and the support rod 4 drives the connecting sleeve 5 to move forward, and the connecting sleeve 5 drives the block 6 to slide inside the slot 7. When the block 6 slides to the front end of the slot 7, the sleeve 3 moves to the top of the pillar 2, and gravity drives the sleeve 3, the support rod 4, the connecting sleeve 5 and the block 6 to descend, and the block 6 and the inner wall of the slot 7 conflict with each other, fixing the support rod 4 and the connecting sleeve 5, so that the support rod 4, the bracket 1 and the sleeve 3 form a stable triangle. , thereby increasing the supporting stability of the bracket 1 and the sleeve 3, and then the user lifts the hanging plate 9. When the hanging plate 9 is lifted, the connecting rod 10 drives the shaft plate 1103 to rotate on the surface of the shaft rod 1102, driving the spring 1104 to deform until the connecting rod 10 is parallel to the mounting plate 8 and stops. Then the connecting rod 10 is rotated to both sides, driving the reset shaft 11 and the connecting rod 10 to move inside the slide groove through the slider. When the reset shaft 11 and the connecting rod 10 move to the inside of the bearing sleeve 12, the user lets go. At this time, the rebound force of the spring 1104 drives the connecting rod 10 and the hanging plate 9 to reset. The connecting rod 10 contacts the inner wall of the bearing sleeve 12, and the connecting rod 10 and the hanging plate 9 are fixed by the bearing sleeve 12, so that the hanging plate 9 and connecting rod 10 always maintain a state of being parallel to mounting plate 8, then the user hangs the sandbag under hanging plate 9 and starts boxing exercise. After the exercise, the user can gather connecting rod 10 to the middle, so that connecting rod 10 moves out of the inside of bearing sleeve plate 12, and then the resilience of spring 1104 drives shaft plate 1103, connecting rod 10 and hanging plate 9 to reset, so that connecting rod 10 and hanging plate 9 are attached to pillar 2, and then lift sleeve 3 to drive support rod 4, connecting sleeve 5 and block 6 to rise, and then press sleeve 3 down to drive connecting sleeve 5 and block 6 to move backward until support rod 4 is parallel to and attached to bracket 1. When the user uses the device, he can operate it in a few simple steps. The device is unfolded, and then the sandbag is hung under the hanging plate 9 to complete the installation. When not in use, the device can be folded and placed in an empty space at home. The structure is placed separately, and does not need to be installed with the wall through bolts and other parts, and does not need to damage the wall. After folding, it can be placed at any place in the home without obstruction, and the user can move it to other places for use according to their own needs or environment. Compared with the traditional bolt installation method, the structure can be flexibly moved to avoid being unable to move easily after installation, and avoid the external environment affecting the use of the device. The installation and folding are relatively convenient, and the triangular support structure is very stable and will not cause violent shaking or tipping when the user exercises. When the user uses the device, the user can pull the pillar 2 above the sleeve 3 to drive the pillar 2, the mounting plate 8 and the hanging plate 9 to move upward, so as to adjust the height of the sandbag. The pillar 2 drives the gear 1 14 to rotate clockwise through the tooth groove 15, and the gear 1 14 drives the gear 2 16 and the gear 3 17 to rotate counterclockwise. When the gear 3 17 rotates, the tooth block on the surface conflicts with the clamp rod 18, because the tooth block is distributed in the counterclockwise direction on the surface of the gear 3 17, and the tooth block is a right-angled trapezoid. When the tooth block conflicts with the clamp rod 18, the tooth block contacts the clamp rod 18 at an inclined surface. At this time, the tooth block The card rod 18 is driven to rotate upward, so that the card rod 18 will not hinder the rotation of gear three 17, and the card rod 18 is driven by gravity to keep in contact with the tooth block, and gear three 17 can rotate freely. When the user pulls the pillar 2 to a suitable position, gravity drives the pillar 2 to descend, and drives gear one 14, gear two 16 and gear three 17 to rotate in the opposite direction through the tooth groove 15. At this time, gear three 17 conflicts with the card rod 18, so that gear three 17 cannot rotate freely, thereby locking gear two 16 and gear one 14, and fixing the position of the pillar 2 through the tooth groove 15. When the sandbag is to be stored or adjusted downward, the user presses the button 19 to drive the lever 18 and the button 19 to rotate clockwise, and the lever 18 is no longer in contact with the gear 3 17 and the tooth block, and then the pillar 2, the mounting plate 8 and the hanging plate 9 can move freely, so that the user can adjust the sandbag downward or store the pillar 2 into the sleeve 3, and then the user releases the button 19. Because the weight of the lever 18 and the accessory block on its surface is greater than the weight of the button 19, when the user releases the button 19, the lever 18 is driven by gravity to rotate counterclockwise, so that the lever 1 8 again conflicts with the tooth block on the gear three 17. This structure allows the user to adjust the height of the device through simple operations, thereby adjusting the height of the sandbag, so that the device can freely adjust the position of the sandbag according to the height of the user, so that the sandbag can be located in a suitable use position, avoiding the situation where the position of the sandbag cannot be adjusted, resulting in the user being unable to fully and reasonably use the limbs for exercise during striking exercises, and the adjustment method is simple, and after use, the upper and lower groups of pillars 2 can be retracted into the sleeve 3, which greatly reduces the space occupied by the device.
